Description

  The present invention relates to a slot machine capable of generating a predetermined winning according to a display result of a variable display device capable of variably displaying a plurality of types of symbols each identifiable.

  Conventionally, as this type of slot machine, an internal lottery is performed to determine whether or not a winning is allowed, and when winning is won in this internal lottery, for example, a variable display device composed of a plurality of reels is won. Controls to match the combinations of symbols corresponding to winnings, and controls not to match the combinations of symbols corresponding to winnings that are not won in the internal lottery. Is common.

  As described above, there are mainly a control method and a table method as a method for controlling the combination of symbols corresponding to winning according to the result of the internal lottery so as not to be aligned or aligned. In the control method, when a stop operation is performed, it is determined whether or not the symbol corresponding to the lottery result is located within the drawing range to the winning line, and if the symbol is within the drawing range, the symbol is drawn into the winning line. If the symbol that does not correspond to the lottery result is located on the winning line, the symbol corresponding to the lottery result is stopped on the winning line. The kick control is performed so as not to occur (see, for example, Patent Document 1). Further, in the table system, a reel table that defines a symbol to be stopped on the winning line at each stop operation timing is stored in advance, and when the stop operation is performed, a reel table corresponding to the lottery result of the game is stored. With reference to the timing at which the stop operation is performed, the above-described pull-in control and kick-off control are realized by performing control to stop the symbols determined on the reel table on the winning line (for example, Patent Documents) 1)

  On the other hand, in order to increase the expectation for winning a special prize that triggers the transition to a special gaming state (for example, a big bonus) advantageous to the player, together with the display result of the variable display device, As a result of the display, a specific display result (so-called chance item) that may be derived, whether or not a special prize is won, is derived on the condition that it is derived. One that executes a specific effect (so-called chance notice) that notifies the possibility of winning a special prize has been proposed (see, for example, Patent Document 2).

  As described above, in the case of using the control method as the control for deriving the display result of the variable display device, the pull-in control and the kicking control are uniquely performed according to the result of the internal lottery. It became monotonous and lacked interest. On the other hand, with the table method, by preparing a plurality of reel tables for one lottery result, it is possible to derive different display results even if the lottery result is the same. Although the display results can be diversified, it is necessary to perform a lottery for selecting one table from a plurality of reel tables with respect to one lottery result, and the control process increases. There was a problem of becoming complicated.

  Further, in the slot machine of Patent Document 2, for example, when the control method is used as the control for deriving the display result of the variable display device as described above, the design of the specific display result that triggers the specific effect is obtained. By limiting the number, it is necessary to adjust the appearance rate of a specific display result, but it is always variable when the specific display result is difficult to be derived (the timing at which the design result of the specific display result does not exist in the drawing range) When the stop operation of the display device is performed, the rate at which the specific effect is executed becomes extremely low, and there is a problem that the player's expectation that a special prize has occurred cannot be sufficiently increased. It was.

  On the other hand, when the table method is used, a lottery result is the same by preparing a first reel table that draws a specific display result and a second reel table that does not draw a specific display result. Even so, it is possible to adjust the appearance rate of a specific display result by selecting the first reel table and the second reel table with a certain probability. There is a problem that the lottery for selecting one table from a plurality of reel tables needs to be performed on the lottery result, and the control process increases, so that the control becomes complicated.

  The present invention has been made paying attention to such problems, and provides a slot machine that can effectively enhance interest by the display result and effect of the variable display device without complicating the control. For the purpose.

In order to solve the above-described problem, a slot machine according to claim 1 of the present invention provides:

With
The derivation control means includes
In a situation where a display result has already been derived in any one of the plurality of variable display areas and a display result has not yet been derived in another variable display area, a display result has not yet been derived. for unresolved variable display area, derived for unresolved operation timing which is the timing of deriving operating means is operated corresponding to the unresolved variable display area among the plurality of the predetermined timing for one cycle From the plurality of control patterns that uniquely specify the display result, the determination result of the pre-determining means and the already derived variable display of the plurality of timings in the already derived variable display area where the display result has already been derived A control pattern for uniquely selecting a control pattern corresponding to an already derived operation timing that is a timing at which the deriving operation means corresponding to a region is operated. Including turn selection means,
When deriving operation means corresponding to the unresolved variable display region is operated, the control pattern selected for the unresolved variable display area by the control pattern selecting means is uniquely identified from the unresolved operation timing Control to derive the display result as the display result of the variable display area,
The control pattern selection means includes
When the already derived operation timing is a first timing and a predetermined display result is derived in the already derived variable display area, the underived operation timing in the underived variable display area is a specific timing, and the already derived operation timing The predetermined display result is similarly derived in the already derived variable display area at a second timing that is different from the first timing, and the underived operation timing in the underived variable display area is also the specific timing. And different control pattern selection means for selecting control patterns with different display results specified from the specific timing , and
Wherein as the control pattern unresolved variable display area, the when determining the result of the pre-determination means is a first determination result, the specific display results from at least one of the timing of the unresolved operation timing specified The first specific control pattern to be selected, and when the determination result of the prior determination means is a second determination result that is more advantageous to the player than the first determination result , Among these, the specific control pattern selecting means for selecting the second specific control pattern in which the specific display result is specified from the number of times higher than the number of timings in which the specific display result is specified in the first specific control pattern. When,
Including
The specific effect executing means is
A first specific effect execution means for executing the specific effect when a combination of display results of the plurality of variable display areas becomes a specific combination including the specific display result;
It is means for determining whether or not to execute the specific effect, and when the determination result of the prior determination means is the second determination result, the probability is higher than when the determination result is the first determination result. Specific production determining means for determining to execute the specific production;
When the specific effect determining means determines to execute the specific effect, the specific effect is executed regardless of whether or not the combination of the display results of the plurality of variable display areas is the specific combination. Two specific performance execution means;
It is characterized by including.
According to this feature, in the situation where the display result has already been derived in any one of the plurality of variable display areas and the display result has not yet been derived in the other variable display areas, the display result has not yet been derived. For a non-derived variable display area from which no derivation has been derived , a plurality of items that uniquely identify a display result derived with respect to an underived operation timing that is a timing at which the derivation operation means corresponding to the underived variable display area is operated From the control pattern, the derivation operation means corresponding to the already derived variable display area among the plurality of timings is operated in the determination result of the predetermination means and the already derived variable display area from which the display result has already been derived. selected control pattern is uniquely corresponding to the already derived the operation timing is a timing, to derive the displayed results to unresolved variable display area corresponding Control is performed. That is, there is only one control pattern applied to the already derived operation timing corresponding to the already derived variable display area from which the display result has already been derived as a result of the determination by one predetermining means, and any one of a plurality of control patterns can be selected. There is no need to further select one control pattern, and the control for deriving the display result of the variable display device is not complicated.
Also, according to the display result of the variable display area for which the display result has already been derived, the control result of the underived variable display area for which the display result has not yet been derived is not selected, but the display result has already been derived. The control pattern of the underived variable display area for which the display result has not yet been derived is uniquely selected according to the already derived operation timing at which the derivation operation means corresponding to the already derived variable display area is operated. A predetermined display result is derived in the already derived variable display area with the already derived operation timing being a first timing, and the underived operation timing in the underived variable display area is a specific timing; The predetermined table is also displayed in the already derived variable display area at a second timing when the already derived operation timing is different from the first timing. Results are derived, and when said unresolved operation timing in the unresolved variable display area is equally the specific timing, in such display result identified from the specific timing is different control patterns each of which is selected It has become . That is, the control pattern of the underived variable display area where the display result has not yet been derived can be changed according to the timing at which the derivation operation means for deriving the derived display result is operated. The display results of the variable display device can be diversified as compared with the case of selecting the control pattern of the underived variable display area for which the display result has not yet been derived according to the derived display result.
Further, as the control pattern of the underived variable display area, when the determination result of the predetermination means is the second determination result, the control pattern is larger than the first specific control pattern selected when the determination result is the first determination result. Since the second specific control pattern in which the specific display result is specified is selected from the timing of and the control for deriving the display result in the corresponding underived variable display area is performed, the determination result of the predetermining means is the second When the result is the determination result, the specific display result is derived at a higher rate than when the determination result is the first determination result, and the specific display result is derived. Can increase the player's expectation that the second determination result is more advantageous to the player than the first determination result.
Further, the specific effect is executed when the combination of the display results of the plurality of variable display areas becomes a specific combination including the specific display result. That is, since the specific effect is executed in relation to the derivation of the specific display result that may be the second determination result, the determination result of the predetermining means is related to the display result of the variable display device and the display result. It is possible to enhance the player's expectation that the determination result of the prior determination means is a second determination result that is more advantageous to the player than the first determination result by both effects.
In addition, when the control for deriving the display result based on the control pattern uniquely selected corresponding to the determination result of the predetermining means is performed, the ratio of deriving the specific display result is extremely reduced. However, when execution of the specific effect is determined by the specific effect determination means, the specific effect is executed regardless of whether or not the specific effect including the specific display result is obtained. Even if the ratio at which the specific display result is derived is extremely reduced, the specific effect is appropriately executed, so that the determination result of the predetermining means is more advantageous for the player than the first determination result. It is possible to effectively increase the player's expectation for being a result.

Note that the predetermined number of bets is at least one bet number, and a game can be started by setting a bet number of two or more or setting a maximum bet number. good. Further, the game may be started by setting a bet amount determined according to a plurality of game states.
Further, the display result derived with respect to the non-derivation operation timing that is the timing at which the derivation operation means corresponding to the non-derivation variable display area among a plurality of timings predetermined for one period is operated is uniquely determined. The control pattern to be identified is a control pattern in which the same display result is always specified as the derived display result when the underived operation timing, which is the timing at which the derivation operation means is operated, is the same. individual for each timing, display results from the variation amount table fluctuation amount until the stipulated derived uniquely identified control pattern display results derived for deriving operation means is operated timing, The timing at which the derivation operation means is operated from the priority table in which the priority of the derived display result is determined for each timing. This corresponds to a control pattern for uniquely specifying a display result derived with respect to the derivation operation timing . In addition, from the non-derivation operation timing that is the operation timing of the derivation operation means, pull-in control is performed so that the display result to be pulled in is maximized within a predetermined pull-in range, and the display result is not prohibited from being derived. Thus, in the case of performing the kicking control that draws the display result other than the display result for which the derivation is prohibited, the display result derived from the non-derivation operation timing that is the timing when the derivation operation means is operated is uniquely specified. If it is a thing, it corresponds to the control pattern of this invention.
Further, the predetermination means determination result, and previously timing the derived operating means is operated corresponding to 該既derived variable display area of the plurality of timing in the previously derived variable display area displays the results derived The unique selection of the control pattern corresponding to the already derived operation timing is that the determination result of the predetermining means is the same, and the derivation corresponding to the already derived variable display area from which the display result has already been derived This is to always select the same control pattern when the already derived operation timing, which is the operation timing of the operation means, is the same, and when the determination result of the predetermining means is different or the already derived display result has already been derived. This does not prevent the selection of a common control pattern when the already derived operation timing corresponding to the variable display area is different.
In addition, when the control pattern corresponding to the already derived operation timing , which is the timing at which the derivation operation means corresponding to the already derived variable display area for which the display result has already been derived is operated , is selected, the display result is already derived. When the derived operation timing corresponding to the already derived variable display area is the same when the derived operation timing is the same, the same control pattern is always selected, for example, corresponding to each timing The control pattern to be selected may be uniquely selected.
Further, the control pattern selection means may be configured such that a display result has already been derived in any one of the plurality of variable display areas and a display result has not yet been derived in another variable display area. for unresolved variable display area not yet displayed results are derived, unique display results derived for unresolved operation timing which is the timing of deriving operating means is operated corresponding to the unresolved variable display area The derivation corresponding to the already derived variable display area of the plurality of timings in the already derived variable display area in which the determination result of the predetermination means and the display result have already been derived from the plurality of control patterns specified in While the operating means are those uniquely selecting the corresponding control pattern already derivation operation timing at which is operated, said control pattern In a situation where the display selection result has already been derived in any two or more variable display areas of the plurality of variable display areas and the display results have not yet been derived in other variable display areas. A plurality of controls for uniquely specifying a display result derived with respect to an underived operation timing that is a timing at which a derivation operation means corresponding to the variable display region is operated for a variable display region for which a display result is not derived. A control pattern corresponding to the combination of the determination result of the prior determination means and the already derived operation timing corresponding to two or more already derived variable display areas from which the display result has already been derived is selected from the pattern. may be in, in such a case, the determination result of the one pre-determining means, corresponding to the two or more previously derived variable display area already displayed result is derived That already derive operating only one control pattern is applied to one of a combination of timing, further there is no need to select one of the control patterns from a plurality of control patterns, deriving a display result of the variable display device It does not complicate the control when making it.
Further, the control pattern selection means has already derived a display result in any two or more variable display areas of the plurality of variable display areas, and has not yet derived a display result in other variable display areas. In the situation, for the underived variable display area for which the display result has not yet been derived , the determination result of the predetermining means and the already derived variable display area for which the display result has already been derived from the plurality of control patterns. The already derived operation timing that is the timing when the derivation operation means corresponding to the already derived variable display area is operated , and the other variable display of the already derived variable display area from which the display result has already been derived A control pattern corresponding to the display result derived in the area may be uniquely selected. In this case, one pre-determining means Determination result, already displayed results already derived the operation timing corresponding to at least one already derived variable display area among the already derived variable display area derived, and already displayed results already derived variable display area of the derived There is only one control pattern applied to one display result derived in another already derived variable display area, and there is no need to further select any one control pattern from a plurality of control patterns. Control for deriving the display result of the apparatus is not complicated.
Further, the specific control pattern selecting means, when the determination result of said predetermination means is a first determination result, still one of the unresolved among the unresolved variable display area where the display result is not derived The first specific control pattern is selected for any two or more variable display areas of the one that selects the first specific control pattern only for the variable display area or the underived variable display area for which the display result has not yet been derived. The first specific control pattern may be selected for all of the underived variable display areas for which display results have not yet been derived , and furthermore, the already derived variable display areas for which display results have already been derived. to display the results on condition that derived in a particular order, the unresolved variable display area not yet displayed result is derived, also selects the first specific control pattern It may be. Similarly, the advance when determining means determines the result is the second determination result, still display result is not derived unresolved variable display second only one of the unresolved variable display area in the region of and used to select a particular control pattern, which selects the second specific control patterns for any two or more unresolved variable display area of the unresolved variable display area not being derived is still displayed results, yet display The second specific control pattern may be selected for all of the underived variable display areas for which results have not been derived . Further, the display results of the already derived variable display areas for which the display results have already been derived are identified. The second specific control pattern may be selected for an underived variable display area for which a display result has not yet been derived on the condition that the display result has been derived in this order.
Also, the out of unresolved operation timing, the second specific control said specific display results from a number of timing than the number of the timing of identifying the particular display results in the first particular control pattern is a specific pattern If the control pattern is based on the variation amount table, the variation amount table in which the variation amount resulting in a specific display result is determined at more timings than the variation amount table applied in the first specific control pattern. If it is a control pattern to be applied and the control pattern is based on the priority table, a priority table in which the priority of the specific display result is set relatively higher than the priority table applied in the first specific control pattern is applied If the control pattern is a control pattern based on the pull-in control and the kick-off control, the first specific control pattern There is a control pattern for performing pull-in control to draw specific display results in a wide pull-in range than when it is selected.
The specific combination including the specific display result may be a combination of display results including a specific display result for any one variable display area, or about any two or more variable display areas. A combination of display results including specific display results may be used, or a combination of display results including specific display results for all variable display areas.
The first specific effect executing means executes the specific effect when a combination of display results of the plurality of variable display areas becomes a specific combination including the specific display result. The specific effect may be executed when the specific display result is derived, and even in this case, the specific effect is executed when the specific combination is derived. That is, since the specific effect is executed in relation to the derivation of the specific display result that may be the second determination result, the determination result of the predetermining means is related to the display result of the variable display device and the display result. It is possible to enhance the player's expectation that the determination result of the prior determination means is a second determination result that is more advantageous to the player than the first determination result by both effects.
Further, the second determination result that is more advantageous to the player than the first determination result is a determination result that can be expected to acquire more game value than the first determination result. The decision result corresponds to a result indicating that a special prize accompanying the transition to a gaming state in which a large number of gaming values can be expected is not allowed, and the second decision result includes the above-mentioned special For example, a result indicating that a winning is permitted is applicable. In addition, as a first determination result, a result indicating that the occurrence of a first special prize accompanying a transition to a gaming state in which a first amount of gaming value can be expected is allowed is applied, As a result of the determination of 2, a result indicating that the occurrence of a second special prize accompanied by a transition to a gaming state in which a second amount of gaming value greater than the first amount can be expected is permitted. It may be applied.

A slot machine according to claim 2 of the present invention is the slot machine according to claim 1,
The specific control pattern selection means includes
When the determination result of said predetermination means is a first determination result, corresponding to at least one timing out of the already derived the operation timing of the already-derived variable display predetermined display results in the area is derived the addition to selecting the first specific control pattern, the unresolved operation timing in response to other timing of the already derived the operation timing of the already-derived variable display said display result which is determined in advance region is derived Te A non-specific control pattern that specifies a display result other than the specific display result from any timing ,
When the determination result of said predetermination means is the second determination result, wherein among the already derived the operation timing, the first of the previously derived variable display area said predetermined display results are derived The second specific control pattern is selected corresponding to more timings than the number of timings when the first specific control pattern is selected when it is a determination result.
According to this feature, when the determination result of the prior determination means is the second determination result, the display result has already been derived in at least one variable display area among the plurality of variable display areas, and the other variable in situations that are not derived is still displayed result on the display area, already a first determination result of the previously derived operating timing already deriving display result was derived variable display predetermined display results in the area is derived Since the second specific control pattern is selected corresponding to more timings than the number of timings at which the first specific control pattern is selected at a certain time, the determination result of the predetermining means is the second determination result. In some cases, the specific display result is derived at a higher rate than in the case of the first determination result. By deriving the specific display result, It is possible to increase the player's expectation for that decision result is an advantageous second determination result for the player than the first determination result.
The specific control pattern selection unit is configured to determine the first derivation operation timing from which the predetermined display result is derived when the determination result of the prior determination unit is the second determination result. determination result in which the first specific control patterns corresponding to the number of timing than the number of timing is selected when selecting the second specific control pattern, said predetermined display result derivation of It said to correspond to the other timing among the already derived the operation timing may be selected to the non-specific control pattern, the other of the previously derived operating timing at which the display result predetermined is derived of it may also be in response to the timing for selecting the first specific control pattern, the previously derived operating timing of said predetermined display result is derived In response to the hand it may be to select the second specific control patterns.
Further, the control pattern selection means has already derived a display result in any two or more variable display areas of the plurality of variable display areas, and has not yet derived a display result in other variable display areas. In the situation, for the underived variable display area for which the display result has not yet been derived , the determination result of the pre-determining means and the two or more already derived variable displays for which the display result has already been derived from the plurality of control patterns When a control pattern corresponding to a combination of already derived operation timings , which is the timing when the deriving operation means corresponding to the region is operated , is selected, or the determination result of the prior determination means and the display result are already derived already derive steering a timing at which the derivation operation means is operated is operated corresponding to at least one variable display area in the variable display area that is Timing, and already when uniquely selects a control pattern corresponding to another previously derived variable display area derived displayed results of the already derived variable display area displays the results derived, the particular control pattern The selection means, when the determination result of the prior determination means is the first determination result, at least one already derived variable display of two or more already derived variable display areas from which the display result has already been derived a timing deriving operating means is operated corresponding to the region, the variable display predetermined display result area corresponding to at least one timing out of the already derived the operation timing which is derived the first specific with selecting a control pattern, the unresolved steering in response to other timing of the already derived the operation timing of the display results predetermined it is derived Select nonspecific control pattern display result other than the specific display result is identified from any of the timing of the timing, when the determination result of said predetermination means is the second determination result, the The first corresponding control pattern is derived in response to more timings than the number of timings when the first specific control pattern is selected when the first determination result among the already derived operation timings at which a predetermined display result is derived . Two specific control patterns may be selected. Even in this case, the specific display result is derived at a higher rate when the determination result of the prior determination means is the second determination result than when the determination result is the first determination result. Thus, by deriving a specific display result, the player's expectation that the determination result of the prior determination means is the second determination result that is more advantageous to the player than the first determination result is increased. Can do.

It becomes a state. In this embodiment, as the specified number of bets, three are determined in the normal gaming state described later and the small bonus game during the big bonus, and one is determined in the regular bonus described later. Yes. If medals are inserted beyond the prescribed number corresponding to the gaming state, the amount is added to the credit.

  When the start switch 7 is operated in a state where the game can be started, the reels 2L, 2C, and 2R rotate, and the symbols of the reels 2L, 2C, and 2R continuously vary. When any one of the stop switches 8L, 8C, 8R is operated in this state, the rotation of the corresponding reels 2L, 2C, 2R is stopped, and the display result is derived and displayed on the fluoroscopic window 3.

  Then, when all the reels 2L, 2C, 2R are stopped, one game is completed, and a predetermined symbol combination on each of the activated pay lines L1-L5 is a reel 2L, 2C, 2R. When the display result is stopped, a winning occurs, and a predetermined number of medals are awarded to the player and added to the credit. Further, when the credit reaches the upper limit number (50 in this embodiment), medals are paid out directly from the medal payout opening 9 (see FIG. 1). In addition, when a combination of symbols accompanying the transition of the gaming state is stopped as a display result of each reel 2L, 2C, 2R on any of the activated pay lines L1 to L5, a game corresponding to the combination of symbols Transition to the state.

  FIG. 3 is a block diagram showing the configuration of the slot machine 1. As shown in FIG. 3, the slot machine 1 is provided with a game control board 40, an effect control board 90, and a power supply board 100. The game state is controlled by the game control board 40, and the game state is controlled by the effect control board 90. The power supply board 100 generates drive power for the electrical components constituting the slot machine 1 and supplies the drive power to each unit.

  The power supply board 100 is supplied with AC100V power from the outside, and from this AC100V power supply, a DC voltage necessary for driving electrical components constituting the slot machine 1 is generated, and the game control board 40 and the game control board 40 are generated. It is supplied to the production control board 90 connected through the. Further, the above-described hopper motor 34, payout sensor 35, stop switch 36, setting key switch 37, reset / setting switch 38, and power switch 39 are connected to the power supply substrate 100.

  Connected to the game control board 40 are the above-described one-sheet BET switch 5, MAXBET switch 6, start switch 7, stop switches 8L, 8C, 8R, settlement switch 10, reset switch 23, insertion medal sensor 31, and reel sensor 33. In addition, the above-described payout sensor 35, stop switch 36, setting key switch 37, and reset / setting switch 38 are connected via the power supply substrate 100, and detection signals of these connected switches are input. It is like that.

  Further, the game control board 40 includes the credit display 11, the game auxiliary display 12, the payout display 13, 1 to 3 BET LEDs 14 to 16, the insertion request LED 17, the start valid LED 18, the waiting LED 19, the replaying LED 10, and the BET. The switch effective LED 21, left, middle, and right stop effective LEDs 22L, 22C, and 22R, the set value display 24, the flow path switching solenoid 30, and the reel motors 32L, 32C, and 32R are connected to each other, and are described above via the power supply board 100. The hopper motor 34 is connected, and these electric components are driven based on control of a main control unit 41 described later mounted on the game control board 40.

  The game control board 40 is composed of a microcomputer having a CPU 41a, ROM 41b, RAM 41c, and I / O port 41d. The main control unit 41 for controlling the game, random numbers in a predetermined range (0 to 65535 in this embodiment) are used. A random number generation circuit 42 for generating, a sampling circuit 43 for acquiring a random number from the random number generation circuit, and a switch detection circuit 44 for detecting a detection signal input from switches connected to the game control board 40 directly or via the power supply board 100 , A motor driving circuit 45 that controls the driving of the reel motors 32L, 32C, and 32R, a solenoid driving circuit 46 that controls the driving of the flow path switching solenoid 30, and a driving control of various displays and LEDs connected to the game control board 40. The power supply voltage supplied to the LED drive circuit 47 and the slot machine 1 to be monitored is monitored. An interruption detection circuit 48 that outputs a voltage drop signal indicating that to the main control unit 41 when a drop is detected. When the power is turned on or when an initialization command from the CPU 41a is not inputted, a reset signal is sent to the CPU 41a. A reset circuit 49 to be applied and other various devices and circuits are mounted.

  The CPU 41a has an interrupt function (including an interrupt prohibition function) such as a timekeeping function and a timer interrupt, and executes a program (described later) stored in the ROM 41b to perform processing related to the progress of the game. Each part of the control circuit mounted on the control board 40 is controlled directly or indirectly. The ROM 41b stores fixed data such as programs executed by the CPU 41a and various tables. The RAM 41c is used as a work area when the CPU 41a executes a program. The I / O port 41d inputs / outputs a control signal to / from each circuit connected via a signal input / output terminal included in the main control unit 41.

  The main control unit 41 includes a signal input terminal DATA, and detection states of various switches connected to the game control board 40 are input to the input port via the signal input terminal DATA. The input states of these signal input terminals DATA are monitored by the CPU 41a, and the CPU 41a executes a basic process that shifts in stages according to the input states of the signal input terminals DATA, that is, the detection states of various switches.

  In addition, the CPU 41a has an interrupt function as described above, and can execute an interrupt process by interrupting the basic process when an interrupt occurs. In this embodiment, four types of interrupts of interrupts 1 to 4 can be executed. For each interrupt, a counter mode (signal input from a trigger terminal CLK / TRG provided separately from the signal input terminal DATA) is provided. Can be selected and set between an interrupt mode that generates an external interrupt according to the number of times) and a timer mode (an interrupt mode that generates an internal interrupt according to the number of clock inputs of the CPU 41a).

  In the present embodiment, among the interrupts 1 to 4, interrupt 2 is set to the counter mode, interrupt 3 is set to the timer mode, and interrupts 1 and 4 are unused. The trigger terminal CLK / TRG is connected to the above-described power failure detection circuit 48, and the CPU 41a generates an interrupt 2 in response to the input of the voltage drop signal output from the power failure detection circuit 48, and the power failure described later. Execute interrupt processing. Further, the CPU 41a executes a timer interrupt process to be described later by generating an interrupt 3 every time the number of clock inputs reaches a certain number, that is, every certain interval. Moreover, although the interrupts 1 and 4 are set to unused, the interrupts 1 and 4 may generate | occur | produce by noise etc. For this reason, when interrupts 1 and 4 occur, the CPU 41a executes an unused interrupt process that immediately returns to the original process.

  The CPU 41a is set to prohibit other interrupts during execution of interrupt processing based on the occurrence of any one of interrupts 1 to 4, and a plurality of interrupts occurred simultaneously. In this case, interrupts to be executed with priority in the order of interrupts 2, 3, 1, 4 are set. In other words, when interrupt 2 and other interrupts occur simultaneously, interrupt 2 is prioritized and when interrupt 3 and interrupt 1 or 4 occur simultaneously, interrupt 3 is prioritized. To run.

  Further, the CPU 41a temporarily stores the data in use stored in the register in a later-described stack area provided in the RAM 41c at the start of interrupt processing based on the occurrence of any of the interrupts 1 to 4. The data saved in the stack area at the end of the interrupt process is returned to the register.

  As the RAM 41c, a DRAM (Dynamic RAM) is used, and a refresh operation is required to maintain the stored data contents. The CPU 41a is provided with a refresh register 41R (see FIG. 34) for performing this refresh operation. The refresh register 41R is composed of 8 bits, and the lower 7 bits are automatically incremented every time the CPU 41a fetches an instruction from the ROM 41b. The value is updated every execution time of one instruction. Is called.

  The main control unit 41 is also supplied with backup power even during a power failure, and while the backup power is being supplied, the CPU 41a performs a refresh operation to hold the data stored in the RAM 41c. It is like that.

  The random number generation circuit 42 is configured by a counter that counts up and updates the value every time a predetermined number of pulses are generated, as will be described later, and the sampling circuit 43 acquires the numerical value counted by the random number generation circuit 42. . The random number generation circuit 42 defines a range of numerical values to be counted for each type of random number. In this embodiment, 0 to 65535 is defined as the range. The CPU 41a sends an instruction to the sampling circuit 43 in accordance with the processing to acquire the numerical value indicated by the random number generation circuit 42 as a random number (this function is hereinafter referred to as a hardware random number function). Random numbers for internal lottery, which will be described later, are not used as they are extracted by the hardware random number function, but are processed and used by software. Details thereof will be described in detail. The CPU 41a also has a function of updating the numerical value of the specific address in the RAM 41c by the above-described timer interrupt processing and acquiring the updated numerical value as a random number (hereinafter, this function is referred to as a software random number function).

  The CPU 41a transmits various commands to the effect control board 90 via the I / O port 41d. A command transmitted from the game control board 40 to the effect control board 90 is sent in only one direction, and no command is sent from the effect control board 90 to the game control board 40. The transmission line of the command transmitted from the game control board 40 to the effect control board 90 is composed of a strobe (INT) signal line, a data transmission line, and a ground line, and is connected via the effect relay board 80. The game control board 40 and the effect control board 90 are not directly connected.

  Electrical components such as a liquid crystal display 51 (see FIG. 1), a rendering effect LED 52, speakers 53 and 54, and a reel LED 55 disposed on the front door of the slot machine 1 are connected to the rendering control board 90. The components are driven based on control by a later-described sub-control unit 91 mounted on the effect control board 90.

  Similar to the main control unit 41, the effect control board 90 includes a microcomputer having a CPU 91a, ROM 91b, RAM 91c, and I / O port 91d. The effect control board 90 includes a sub control unit 91 for effect control and an effect control board 90. A liquid crystal driving circuit 92 that controls the driving of the connected liquid crystal display 51, a lamp driving circuit 93 that controls the driving of the effect LED 52 and the reel LED 55, an audio output circuit 94 that controls audio output from the speakers 53 and 54, and a power source A reset circuit 95 that gives a reset signal to the CPU 91a when it is turned on or when an initialization command is not input from the CPU 91a, and other circuits are mounted. The CPU 91a receives a command transmitted from the game control board 40. In addition to performing various controls for production, mounted on production control board 90 Directly or indirectly controls each unit of the control circuit.

  Similar to the CPU 41a of the main control unit 41, the CPU 91a has an interrupt function (including an interrupt prohibition function) such as a timer interrupt. An interrupt terminal (not shown) of the sub-control unit 91 is connected to a strobe (INT) signal line that is output when the main control unit 41 transmits a command among command transmission lines. An interrupt is generated based on the input to acquire a command from the main control unit 41 and execute a command reception interrupt process to be stored in the buffer. The CPU 91a executes a timer interrupt process (sub) to be described later by generating an interrupt every time the number of clock inputs reaches a certain number, that is, every certain interval. Also, when an unused interrupt occurs in the CPU 91a, an unused interrupt process for immediately returning to the original process is executed.

  Further, unlike the CPU 41a, when an interrupt is generated based on the input of the strobe signal (INT), the CPU 91a interrupts the process even when an interrupt process based on another interrupt is being executed. The command reception interrupt process is executed at the top, and even if another interrupt occurs at the same time, the command reception interrupt process is executed with the highest priority.

  The sub-control unit 91 is also supplied with backup power at the time of a power failure, and while the backup power is supplied, the CPU 91a performs a refresh operation so that the data stored in the RAM 91c is retained. It has become.

  In the slot machine 1 of this embodiment, the medal payout rate changes according to the set value, and the winning probability of the internal lottery described later is determined according to the set value. Hereinafter, the setting value changing operation will be described.

  In order to change the setting value, it is necessary to turn on the power of the slot machine 1 after the setting key switch 37 is turned on. When the power is turned on with the setting key switch 37 in the ON state, 1 is displayed as the initial value of the setting value on the setting value display 24, and the setting change mode in which the setting value can be changed by operating the reset / setting switch 38 is set. Transition. When the reset / setting switch 38 is operated in the setting change mode, the setting value displayed on the setting value display 24 is updated one by one (when further operation is performed from the setting 6, the setting value is returned to the setting 1). . When the start switch 7 is operated, the set value is confirmed, and the confirmed set value is stored in the RAM 41c of the main control unit 41. Then, when the setting key switch 37 is turned off, the state shifts to a state in which the game can proceed.

  In the slot machine 1 of the present embodiment, when the CPU 41a of the main control unit 41 detects a voltage drop signal, a power interruption interrupt process is executed. In the power interruption processing, the register is saved in a stack of a RAM 41c, which will be described later, and data for destructive diagnosis (5A (H) in this embodiment) in which any bit is 1 in the RAM 41c of the main control unit 41, that is, In addition to storing specific data other than 0, the RAM parity adjustment data is calculated so that the RAM parity based on the data stored in all areas of the RAM 41c becomes 0, and stored in the RAM 41c. ing. The RAM parity is a value calculated as an exclusive OR of values stored in each bit of the corresponding area (all areas in this embodiment) of the RAM 41c. Therefore, if the RAM parity based on the data stored in all areas of the RAM 41c is 0, the RAM parity adjustment data is 0, and the RAM parity based on the data stored in all areas of the RAM 41c is 1. In this case, the RAM parity adjustment data is 1.

  The CPU 41a calculates the RAM parity based on the data stored in all areas of the RAM 41c at the time of activation, confirms the value of the destructive diagnosis data, the RAM parity is 0, and the destructive diagnosis On the condition that the data value is also correct, the processing state of the CPU 41a is restored to the state before the power interruption based on the data stored in the RAM 41c. If the data value is not correct, it is determined that the RAM is abnormal, and a RAM abnormal error code is set in the register to control the RAM abnormal error, thereby disabling the progress of the game. Unlike the other error states, the RAM abnormal error state is not canceled even if the reset switch 23 or the reset / setting switch 38 is operated, and a new set value is set in the setting change mode described above. It will not be released until

  In the slot machine 1 according to the present embodiment, the prescribed number of bets that can be set according to the gaming state is determined as described above, and the prescribed number of bets that are determined according to the gaming state is set. It becomes possible to start the game on the condition. In this embodiment, as will be described later, there are a regular bonus, a small role game in a big bonus, and a normal gaming state as a gaming state. Among these, 1 is defined as the prescribed number of bets corresponding to the regular bonus. The prescribed number of bets corresponding to the small role game and the normal gaming state is set to 3. Therefore, when the gaming state is a regular bonus, the game can be started when 1 is set as the bet number, and when the gaming state is the small role game or the normal gaming state, 3 is set as the bet number. Then, the game can be started. In this embodiment, when a specified number of bets corresponding to the gaming state is set, all winning lines L1 to L5 are activated, and the specified number corresponding to the gaming state is If it is 1, all winning lines L1 to L5 are activated when 1 is set as the bet number, and if the specified number is 3 according to the gaming state, 3 is set as the bet number. All winning lines L1 to L5 are activated.

  In the slot machine 1 of this embodiment, when all the reels 2L, 2C, and 2R are stopped, if a combination of symbols called “combinations” is arranged on the activated winning line (hereinafter referred to as an effective line), Become. The type of winning combination is determined according to the game state, but it can be roughly divided into a small role with payout of medals and a replay that can start the next game without the need to set the number of bets. There are a game combination and a special combination with a transition of the game state. In order for each winning combination determined according to the gaming state to occur, it is necessary to win an internal lottery to be described later and set a winning flag for the winning combination.

  Of the winning flags for each of the winning combinations, the winning flag for the small role and the replaying role is valid only in the game in which the flag is set and is cleared at the end of the game. Is valid until a combination of combinations permitted by the flag is completed, and is cleared in a game having a combination of combinations permitted. In other words, once the winning flag for the special role is won, even if the combination of the characters allowed by the flag cannot be aligned, the winning flag is not cleared and it is carried over to the next game. Become. However, as will be described later, the combination of JACIN among the special roles will always be aligned with the winning game, so it will not be carried over to the next game, only the winning flags of other special roles will be If the combination of allowed combinations is not complete, it will be carried over to the next game.

  FIG. 4A is a diagram showing a winning combination table by gaming state. The gaming state winning combination table is stored in advance in the ROM 41b of the main control unit 41 and is used to determine the combination determined to be winning in the internal lottery. The combination determined according to the game state is shown. In this slot machine 1, JAC, Cherry, and Bell as small roles are replayed as re-playing roles, and special bonuses include a big bonus (1), a big bonus (2), a regular bonus (1), and a regular bonus (2 ), JACIN is defined.

  In the regular bonus game state, JAC, cherry, and bell, which are small roles, are determined as winning combinations, and are subject to lottery in the internal lottery in the regular bonus. In the small bonus game described later of Big Bonus, the small bonuses Cherry and Bell, the special bonus Regular Bonus (2), and JACIN are determined as winning roles. It is said. In the normal gaming state, cherry and bell as small roles, replay as replaying roles, big bonus (1), big bonus (2) and regular bonus (1) as special roles are defined as winning roles. In the normal game state, the lottery is a lottery target.

  In the present embodiment, in the regular bonus game state, JAC is determined as a small winning combination in addition to cherry and bell. However, in the regular bonus gaming state, the small bonus game and the normal gaming state Similarly, only the cherry and the bell may be determined as winning small roles.

  JAC wins when the combination of “Replay-Replay-JAC” is aligned on the active line in the regular bonus, but in the gaming state other than the regular bonus, even if this combination is aligned, JAC is not awarded. Cherry is awarded when the symbol “cherry” is derived to any of the active lines for the left reel 2L in any gaming state. A bell is awarded when a combination of “bell-bell-bell” is arranged on any of the active lines in any gaming state. The payout of medals when these small roles are won will be described later.

  Replay is awarded when a combination of “Replay-Replay-Replay” is aligned on any of the active lines in the normal gaming state, but this combination is used for regular bonuses and big bonuses (small-games and regular bonuses). Even if it is complete, it will not be a replay prize. When a replay is won, the medals will not be paid out, but the next game can be started without setting the number of bets again, so the number of bets no longer required to be set in the next game (the regular bonus will not be replayed and will always be 3) This is substantially the same as when three corresponding medals are paid out.

  The big bonus is awarded when a combination of “BAR-BAR-BAR” or a combination of “7-7-7” is arranged on any of the active lines in the normal gaming state. When the big bonus is won, the gaming state shifts to the big bonus. In the big bonus, a game called a small role game can be played. While the game state is the big bonus, the big bonus medium flag is set in the RAM 41c. The big bonus ends when the total number of medals paid out to the player in the big bonus reaches 465.

  In addition, when it is necessary to distinguish the big bonus by “BAR-BAR-BAR” and the big bonus by “7-7-7”, they shall be referred to as big bonus (1) and big bonus (2), respectively. . The big bonuses (1) and (2) are further subdivided according to the order in which the winning is determined in the internal lottery. When these are distinguished, the big bonus (1) -A, These are referred to as big bonus (1) -B, big bonus (2) -A, and big bonus (2) -B.

  The regular bonus is awarded when a combination of “7-7-BAR” is arranged on any of the active lines in the small role game and the normal gaming state. When the regular bonus is won, the gaming state shifts from the small role game or the normal gaming state to the regular bonus. The regular bonus ends when 12 games are consumed, or when 8 games are won (any kind of combination is possible), whichever comes first. While the game state is in the regular bonus, the regular bonus medium flag is set in the RAM 41c. In particular, when a regular bonus is won in the small role game, a regular bonus is provided during the big bonus, and the regular bonus medium flag is also set in the RAM 41c in addition to the big bonus medium flag. When the total number of medals paid out to the player in the big bonus reaches 465 with the regular bonus in the big bonus, the regular bonus is terminated together with the big bonus.

  When it is necessary to distinguish between the regular bonus due to “7-7-BAR” in the normal gaming state and the regular bonus due to “7-7-BAR” in the small role game in the big bonus, the regular bonus (1) respectively. This is called regular bonus (2). In addition, the above-described big bonus (1) and big bonus (2), regular bonus (1) and regular bonus (2) may be collectively referred to as “bonus”.

  JACIN wins when a combination of “Bell-Bell-JAC” is found on any of the active lines in the small role game, but in a gaming state other than the small role game, even if this combination is available, JACIN wins. Not. When winning JACIN, the above-described regular bonus is provided during the big bonus, and the regular bonus medium flag is also set in the RAM 41c of the main control unit 41 in addition to the big bonus medium flag. When the total number of medals paid out to the player in the big bonus reaches 465 with the regular bonus in the big bonus, the regular bonus is terminated together with the big bonus.

  Hereinafter, the internal lottery will be described. In the internal lottery, it is determined whether or not the winning of each winning combination is allowed before the display results of all the reels 2L, 2C and 2R are derived and displayed (actually, when the start switch 7 is detected). Is. In the internal lottery, first, as will be described later, a random number for internal lottery (an integer from 0 to 65535) is acquired. Then, for each combination determined according to the gaming state, the acquired internal lottery random number, the bet number set by the player, and the set value set by the reset / setting switch 38 It is performed according to the number of judgment values for the combination. In this embodiment, since the lottery for the small role and the re-playing role and the lottery for the special role are performed separately in the normal gaming state, the winning in the internal lottery is not exclusive, Special roles may be won at the same time.

  In the regular bonus and the small bonus game in the big bonus, the reference of the combination according to the gaming state is performed based on the winning combination table according to the gaming state shown in FIG. 4 (a). It is performed based on both the winning combination table according to gaming state shown in 4 (a) and the combination table for special roles described later shown in FIG. 4 (c).

  When the gaming state is a regular bonus (including the case where the bonus is provided during the big bonus), the JAC, cherry, and bell are sequentially read out as target lots for internal lottery by referring to the winning combination table by gaming state. Is in the small bonus game during the big bonus, cherry, bell, regular bonus (2), and JACIN are sequentially read out as the internal lottery target roles. However, when the regular bonus winning flag (2) is set in the game before the previous time and the game is carried over without winning based on the flag, the regular bonus (2) and JACIN are not subject to the internal lottery.

  When in the normal gaming state, first, a lottery of a small combination and a re-playing combination is performed, and then a lottery of a special combination is performed. In the lottery for the small role and the re-playing role, the winning combination table according to the game state is referred to, and the target small role and the re-playing role in the normal gaming state, that is, cherry, bell, and replay are sequentially read out as the targets for the internal lottery. .

  In the lottery of special roles, refer to the winning status table for each gaming state and the special role table for the special role. It is read in the order registered in another table.

  In addition, in the lottery for special roles, it is determined whether or not the special role is lost while winning is determined for a plurality of special roles. The roles and special roles are registered in the order in which they are judged. For this reason, in the special role lottery, the special combination and the special combination losing are read out in the order registered in the special-function-specific table.

  As shown in FIG. 4 (c), in the special role-specific table, the big bonus (1) -A, the big bonus (2) -A, and the big bonus are shown as special bonuses to be selected in the normal gaming state. (1) -B, Big Bonus (2) -B, Regular Bonus (1) are registered and Loss is registered between Big Bonus (2) -A and Big Bonus (1) -B Therefore, in the special role lottery, Big Bonus (1) -A, Big Bonus (2) -A, Loss, Big Bonus (1) -B, Big Bonus (2) -B, Regular Bonus (1) It will be read out.

  However, if the winning flag of the regular bonus (1), big bonus (1) or big bonus (2) is set in the game before the previous time and the game is carried over without winning based on the flag, the regular bonus (1 ) And big bonuses (1) and (2) are not subject to the internal lottery, so the special role lottery itself is not performed.

  In the internal lottery, the number of determination values determined for the internal lottery target combination is sequentially added to the internal lottery random number, and when the addition result overflows, it is determined that the winning combination is won. When the winning is determined, the winning flag of the combination is set in the RAM 41c of the main control unit 41. The determination value number is read according to the storage address of the determination value number registered in the role-specific table stored in advance in the ROM of the main control unit 41.

  Also, especially in the normal gaming state, when the number of judgment values determined for the small role and the re-playing role that are the target in the normal gaming state is sequentially added to the random number for internal lottery, and the result of the addition overflows It is determined that the winning combination has been won, and the winning flag of the winning combination is set.

  Furthermore, regardless of whether or not the result of the addition of the random numbers for internal lottery overflowed, the number of judgment values determined for the special role that is the target in the normal gaming state (the judgment value that was determined in response to the special role lost) Is added to the random number for internal lottery (the first acquired random number) before addition, and when the result of addition overflows, it is determined that the winning combination is won, and the winning flag of the winning combination is determined. Is set (this is not the case when the result of adding the number of judgment values determined corresponding to the special role loses overflows). That is, in the normal gaming state, both the lottery for the small combination and the re-game combination and the lottery for the special combination are performed based on the same random number for internal lottery.

  As described above, if the winning flag of regular bonus (1), big bonus (1) or big bonus (2) is carried over from the previous game to the previous game, There will be no lottery.

  FIG. 4B is a diagram illustrating an example of a role-specific table for a small role and a re-playing role, and FIG. 4C is a diagram illustrating an example of a role-specific table for a special role (and lose). is there. The number of determination values may be 256 or more, and cannot be stored in one byte. Therefore, each determination value number is registered using a storage area of two bytes.

  The number of determination values for each combination (and lose) is registered corresponding to the number of bets (BET) set by the player in the game. This is because even with the same combination, the winning probability in the regular bonus may differ from other combinations. In addition, the number of determination values corresponding to the number of bets for each combination (and lose) is common regardless of the set value, and is different depending on the set value. If the number of determination values is common regardless of the set value, a common flag is set (value is set to “1”).

  As shown in FIG. 4B, in the role-specific table for the small role and the replaying role, the storage addresses of the judgment value numbers of JAC, cherry, bell, and replay are registered in the order of reference.

  The JAC is a role that is subject to internal lottery only with the regular bonus, and the storage address of the number of determination values corresponding to the bet number 1 with the regular bonus is registered. The common flag of this combination is 0, and the storage address of the judgment value number is registered individually according to the set value corresponding to each bet number.

  Cherry and Bell are the targets that are subject to internal lottery in any gaming state, the storage address of the number of judgment values corresponding to the number of bets 1 in the regular bonus, and the number of bets 3 in the normal gaming state or small role game And the storage address of the number of judgment values corresponding to. For cherry, the common flag is 1, and the storage address of the common number of determination values is registered corresponding to the number of bets regardless of the set value. For the bell, the common flag is 0, and the storage address of the number of determination values is individually registered according to the set value corresponding to each bet number.

  Replay is a role that is subject to internal lottery only in the normal gaming state, and a storage address for the number of determination values corresponding to the bet number 3 in the normal gaming state is registered. The common flag for this combination is 1, and a common storage address for the number of determination values is registered regardless of the set value.

  As shown in FIG. 4C, the special role (and lose) role-specific table includes big bonus (1) -A, big bonus (2) -A, lose, big bonus (1) -B, The storage addresses for the number of determination values for each combination are registered in the order of big bonus (2) -B, regular bonus (1), regular bonus (2), and JACIN.

  The big bonus (1) -A and the big bonus (2) -A are roles that are subject to internal lottery only in the normal gaming state, and the storage address of the number of determination values corresponding to the bet number 3 in the normal gaming state is Each is registered. For these combinations, the value of the common flag is 1, and the storage address of the common determination value number is registered regardless of the set value.

  Loss, Big Bonus (1) -B, Big Bonus (2) -B, Regular Bonus (1) are only eligible for internal lottery in the normal gaming state and correspond to 3 bets in the normal gaming state. The storage addresses for the number of judgment values to be registered are registered. For these combinations, the value of the common flag is 0, and the storage address of the number of determination values is individually registered according to the set value.

  Regular bonus (2) and JACIN are internal lottery targets only in the small bonus game in the big bonus, and the storage address of the number of judgment values corresponding to the bet number 3 in the small bonus game is registered. . The value of the common flag for this combination is 1, and a common storage address for the number of determination values is registered regardless of the set value.

  Also, the number of medals to be paid out when winning each winning combination is registered in the role-specific table. However, only the JAC, Cherry, and Bell, which are small roles, are the targets for which medals are paid out when winning. Cherry and bell can be awarded when the bet number is 1 (regular bonus) or 3 (game state other than the regular bonus), but for the bell, when the bet number is 1, that is, the game When the state is a regular bonus, 15 medals are paid out more than the other seven.

  The big bonus (1), the big bonus (2), the regular bonus (1), the regular bonus (2), and the winning of JACIN are accompanied by a transition of the gaming state and are not eligible for payout of medals. Replay does not involve the payout of medals. However, since it is not necessary to insert medals used for setting the number of bets in the next game, it is substantially the same as paying out 3 medals. Of course, losing special roles are not eligible for medal payout.

  FIG. 5 is a diagram illustrating a storage area for the number of determination values acquired based on addresses registered in the role-specific table. The storage area for the number of determination values is provided in the RAM 41c of the main control unit 41 in the development model, and in the address area allocated to the ROM 41b in the main control unit 41 in the mass production model.

  For example, addresses ADD + 40, ADD + 42, ADD + 44, ADD + 94, and ADD + 96 are set when the internal lottery target is replay, big bonus (1) -A, big bonus (2) -A, regular bonus (2), JACIN, respectively. The addresses are referenced regardless of the value, and 8978, 27, 57, 85, and 23500 are acquired as the number of determination values, respectively, regardless of the set value.

  The address ADD is an address that is referred to when the target role of the internal lottery is JAC and the setting value is 1, and at this time, 51, which is a value stored here, is acquired as the number of determination values. Addresses ADD + 2, ADD + 4, ADD + 6, ADD + 8, and ADD + 10 are addresses that are referred to when the target role of the internal lottery is JAC and the set value is 2 to 6, respectively. For JAC, the same values are registered in addresses ADD, ADD + 2, ADD + 4 and ADD + 6, and ADD + 8 and ADD + 10. Therefore, the winning probabilities of JACs with setting values 1 to 4, setting values 5 and 6 are set. Are the same.

  The addresses ADD + 82, ADD + 84, ADD + 86, ADD + 88, ADD + 90, and ADD + 92 are addresses that are referred to when the internal lottery target is the regular bonus (1) and the set value is 1 to 6, respectively. As for regular bonus (1), the number of judgment values is individually stored according to the set value, but since the same number of judgment values is stored, the winning of regular bonus (1) at any set value Probabilities are the same.

  Addresses ADD + 58, ADD + 60, ADD + 62, ADD + 64, ADD + 66, and ADD + 68 are addresses that are referenced when the internal lottery target is the big bonus (1) -B and the set value is 1-6. Addresses ADD + 70, ADD + 72, ADD + 74, ADD + 76, ADD + 78, and ADD + 80 are addresses that are referenced when the internal lottery target is a big bonus (2) -B and the set value is 1-6. For the big bonuses (1) -B and (2) -B, the number of determination values is individually stored according to the set value, and different determination value numbers are stored. The winning probabilities of 1) -B and (2) -B will be different.

  The address ADD + 12 is an address that is referred to regardless of the set value when the bet number is 1, that is, when the target character of the internal lottery is cherry in the regular bonus. The address ADD + 14 is an address that is referred to regardless of the set value when the bet number is 3, that is, when the target lot of the internal lottery is cherry in the normal gaming state or the small role game. Since different values are registered for the number of cherries according to the number of bets, the winning probability of cherries differs according to the number of bets.

  The addresses ADD + 16, ADD + 18, ADD + 20, ADD + 22, ADD + 24, and ADD + 26 are addresses that are referred to when the bet number is 1, that is, when the target character of the internal lottery is the bell and the set value is 1 to 6 in the regular bonus. is there. Since the same values are registered in the addresses ADD + 16, ADD + 18, ADD + 20 and ADD + 22, and ADD + 24 and ADD + 26, respectively, at the regular bonus, the set values 1 to 4, the set values 5 and 6 are Winning probability is the same.

  Addresses ADD + 28, ADD + 30, ADD + 32, ADD + 34, ADD + 36, and ADD + 38 are each when the number of bets is 3, that is, when the target lot of the internal lottery is a bell and the set value is 1 to 6 in the normal game state or the small role game The address to be referenced. Since the same values are registered in the addresses ADD + 28, ADD + 30, ADD + 32 and ADD + 34, and ADD + 36 and ADD + 38, respectively, in the normal game state or the small role game, the set values 1 to 4, the set value 5 and the set value 6 Thus, the winning probability of Bell is the same.

  Addresses ADD + 46, ADD + 48, ADD + 50, ADD + 52, ADD + 54, and ADD + 56 are addresses that are referred to when the target combination of the internal lottery is lost and the set value is 1 to 6, respectively. Since the same value is registered in each of the addresses ADD + 46, ADD + 48, ADD + 50, ADD + 52, and ADD + 54, ADD + 56, the winning probability of the loss is the same for the setting values 1 to 4, the setting value 5 and the setting value 6. .

  FIGS. 6A, 6B, 7A, 6B, 8A, and 8B are diagrams showing examples of the relationship between the value of the random number for internal lottery and the number of determination values of each combination and the winning combination. . 6 (a), (b) and FIG. 7 show an example when the player is in a normal gaming state, FIG. 8 (a) shows a case in a small role game, and FIG. 8 (b) shows an example in a regular bonus. Yes. 6A, 6B, 7A, and 8B show examples in which the set value is 6, and in FIGS. 6B and 7, regular is shown. An example in which neither a bonus nor a big bonus winning flag is set is shown.

  In the normal gaming state, the roles that are the targets of the internal lottery are regular bonus (1), big bonus (1), big bonus (2), cherry, bell, and replay. Since the lottery for the small role and the re-playing role and the lottery for the special role are performed separately for the same random number for the internal lottery, here, the random value for the internal lottery in the lottery for the small role and the re-playing role and For the internal lottery based on the relationship between the number of judgment values for each role and the winning role, the random value for internal lottery in the lottery for special roles, the relationship between the number of judgment values for each role and the winning role, and the combination of both lotteries The relationship between the value of the random number and the number of determination values for each combination and the winning combination will be described.

  For example, as shown in FIG. 6 (a), the winning roles in the lottery of the small role and the replaying role in the normal gaming state are cherry, bell, and replay. Becomes 655, 13600, and 8978. When the cherry that is the target of the lottery of the small combination and the re-playing combination is added as a random number for internal lottery, the addition result overflows by adding 655 of the judgment value number Will be won.

  Next, the bell that is the subject of the lottery for the small role and the re-playing role adds 14255, which is the sum of the cherry judgment value number 655 and the bell judgment value number 13600, and the addition result overflows 51281. Wins when ˜64880 is acquired as a random number for internal lottery. Similarly, the replay is determined to be a win when 42303 to 51280 are acquired as random numbers for internal lottery.

  The approximate winning probabilities of the small combination and re-playing combination calculated based on the number of determination values are 1 / 100.06, 1 / 4.82, 1 / 7.30 for cherry, bell, and replay, respectively. It becomes. When 0 to 42302 are acquired as random numbers for internal lottery, all the small combinations and re-playing combinations are lost.

  On the other hand, as shown in FIG. 6 (b), in the lottery of special roles in the normal gaming state, the target roles are Big Bonus (1) -A, Big Bonus (2) -A, Loss, Big Bonus (1) -B, Big Bonus (2) -B, Regular Bonus (1). With the set value 6, the number of determination values is 27, 57, 23149, 54, 113, 84, so 65509 to 65535 65, 4552 to 65508, 42303 to 65451, 42249 to 42302, 42136 to 42248, and 422052 to 42135 are determined as random numbers for internal lottery, it is determined that the winning combination (special role is lost). In addition, the approximate winning probabilities of the respective combinations are 1 / 2427.26, 1 / 1149.75, 1 / 2.83, 1 / 1121.63, 1 / 579.96, and 1 / 780.19. Note that when 0 to 42051 are acquired as random numbers for internal lottery, all special roles are lost.

  Then, a random number range (64881 to 65535) for the internal lottery in which the cherry is determined to be won in the lottery of the small role and the replaying role, and the big bonus (1) -A and the big bonus (2)-in the special lottery Since the range of random numbers for internal lottery (65509 to 65535, 65452 to 65508) in which A is determined to be winning overlap, when the values of these overlapping ranges are acquired as random numbers for internal lottery, It is determined that 1) and cherry, and big bonus (2) and cherry are won at the same time.

  Therefore, in the normal gaming state, as shown in FIG. 7, when 65509 to 65535 and 65452 to 65508 are acquired as random numbers for internal lottery, the big bonus (1), cherry, and big bonus (2) are obtained. When it is determined that cherries were won at the same time and 64881 to 65451 were acquired as random numbers for internal lottery, it was determined that only cherries were won by themselves, and 51281 to 64880 were acquired as random numbers for internal lottery On the other hand, when it is determined that only the bell has been won alone and 42303 to 51280 are acquired as random numbers for internal lottery, it is determined that only replay has been won alone, and 42249 to 42302 are used as random numbers for internal lottery. When acquired, it is determined that only the big bonus (1) has been won alone, and 42136 When 42248 is acquired as a random number for internal lottery, it is determined that only the big bonus (2) is won, and when 42052-42135 is acquired as a random number for internal lottery, the regular bonus (1) Only will be determined to have won alone.

  And the approximate probability of winning big bonus (1) and cherry at the same time is 1 / 2427.26, the approximate probability of winning big bonus (2) and cherry at the same time is 1 / 1149.75, and cherry wins alone. The approximate probability of winning is 1 / 1114.77, and the approximate probability of winning the bell, replay, big bonus (1), big bonus (2), and regular bonus (1) alone is 1 / 4.82, 1 /7.30, 1 / 1213.63, 1 / 579.96, 1 / 780.19. In addition, when 0 to 42051 are acquired as random numbers for internal lottery, all combinations are lost.

  As described above, in this embodiment, the number of judgment values stored in the address area registered in the role-specific table for the small role and the re-playing role and the address value registered in the role-specific table for the special role are stored. From the determined number of judgment values, it is possible to specify the range of judgment values that each of the small role, replaying role, and special role wins independently, and the range of judgment values that the small role and special role will win In the internal lottery, the value obtained as a random number for internal lottery is included in the range of judgment values that each of the small role, replaying role, and special role specified by the number of judgment values wins independently. If it is determined that the small role, the replaying role, and the special role are each elected alone, and if the small role and the special role are included in the range of determination values to be won, the small role and the special role Both of them are judged to have won.

  In the normal gaming state, when either the regular bonus or the big bonus winning flag is already set, that is, when these winning flags are set in the previous game and carried over, Since only the re-game winning lottery is performed, the random number value for determining that each winning combination is won and the winning probability for each winning combination are as shown in FIG.

  Further, as shown in FIG. 8A, in the small role game, cherry, bell, regular bonus (2), and JACIN are subject to internal lottery, and the number of determination values is 655, 13600, 85, and 23500, respectively. Therefore, when 64881 to 65535, 51281 to 64880, 51196 to 51280, and 27696 to 51195 are acquired as random numbers for internal lottery, it is determined that the winning is made. In addition, the approximate winning probabilities of the respective roles are 1 / 100.06, 1 / 4.82, 1 / 771.01, and 1 / 2.79. When 0 to 27695 is acquired as a random number for internal lottery, all combinations are lost.

  Further, as shown in FIG. 8B, in the regular bonus, JAC, cherry, and bell are subject to internal lottery, and the numbers of determination values are 51278, 656, and 13601, respectively, so 14258 to 65535 and 13602. When 14257 and 1-13601 are acquired as random numbers for internal lottery, it is determined that the winner is won. In addition, the approximate winning probabilities for each combination are 1 / 1.28, 1 / 99.90, and 1 / 4.82. When 0 is acquired as a random number for internal lottery, all combinations are lost.

  Next, acquisition of random numbers for internal lottery will be described in detail with reference to FIG. The random numbers for the internal lottery are acquired by extracting random numbers from the random number generation circuit 42 by the hardware random number function and processing them by software by the CPU 41a. Note that the least significant bit of the random number extracted from the random number generation circuit 42 or the processed random number is called the 0th bit, and the most significant bit is called the 15th bit.

  FIG. 9A is a block diagram showing the configuration of the random number generation circuit 42 in detail. As shown in the figure, the random number generation circuit 42 includes a pulse generation circuit 42a, a lower counter 42b, and an upper counter 42c. The lower counter 42b and the upper counter 42c are both 8-bit (1 byte) counters, the lower counter 42b is the 0th to 7th bits, and the upper counter 42c is a total of 16 bits from the 8th to 15th bits. The data signal is output.

  The pulse generation circuit 42a outputs a pulse signal at a frequency that is higher than the frequency of the operation clock of the CPU 41a and is not an integral multiple thereof (preferably relatively prime). The pulse signal output from the pulse generation circuit 42a is clocked into the lower counter 42b.

  The lower counter 42b alternately inverts the 0th bit data signal between the H level and the L level every time a pulse signal is input from the pulse generation circuit 42a. Assuming that positive logic is applied, a logical value of H level corresponds to 1 and a logical value of L level corresponds to 0. In the case of negative logic, a logic value of 1 may be read as L level, and a logic value of 0 may be read as H level. When the level of the 0th bit data signal is inverted from H level to L level, that is, whenever the logic value of the 0th bit data signal changes from 1 to 0, the level of the 1st bit data signal is changed to H level. Inverted alternately with L level.

  Similarly, when the level of the (m−1) th bit data signal is inverted from the H level to the L level, that is, whenever the logic value of the (m−1) th bit data signal changes from 1 to 0, the mth bit data The signal level is alternately inverted between the H level and the L level. The carry signal is output every time the level of the seventh bit data signal changes from H level, that is, the logical value of the seventh bit data signal changes from 1 to 0. The carry signal output from the lower counter 42b is clocked into the upper counter 42c.

  The upper counter 42c alternately inverts the eighth bit data signal between the H level and the L level every time a carry signal is input from the lower counter 42b. Each time the level of the 9th bit data signal is inverted from H level to L level, the level of the 9th bit data signal is alternately inverted between H level and L level. Similarly, every time the level of the m−1th bit data signal is inverted from the H level to the L level, the level of the mth bit data signal is alternately inverted between the H level and the L level.

  The logic value of a 16-bit data signal in which the data signal of the lower counter 42b is the lower 8 bits and the data signal of the upper counter 42c is the upper 8 bits is 0 (0000h) every time the pulse generation circuit 42a outputs the pulse signal. ) → 1 (0001h) → 2 (0002h) →... → 65535 (FFFFh) The values are updated so as to be continuous every update, and the maximum value 65535 (FFFFh) is next to the initial value 0 (0000h). The value circulates and is output from the random number generation circuit 42.

  The sampling circuit 43 includes a latch circuit, and latches and latches a 16-bit data signal output from the random number generation circuit 42 at that time based on a sampling command (when the start switch 7 is operated) from the CPU 41a. Output the data signal. The CPU 41a extracts numerical data corresponding to the data signal input from the sampling circuit 43 via the I / O port 41d as a random number generated by the random number generation circuit. In the following description, the data signal output from the random number generation circuit 42 is described as a random number corresponding to the logical value.

  FIG. 9B is an explanatory diagram until the CPU 41a processes the random number extracted from the random number generation circuit 42 into a random number for internal lottery by software. The random number extracted from the random number generation circuit 42 is stored in a 16-bit general-purpose register 41GR included in the CPU 41a.

  When the random number extracted from the random number generation circuit 42 is stored in the general-purpose register 41GR, the CPU 41a uses the other general-purpose register or the work area of the RAM 41c to lower-order the bytes of the general-purpose register 41GR (value extracted from the lower-order counter 42b). And the value of the upper byte (the value extracted from the upper counter 42c) are exchanged. Then, the CPU 41a obtains the value stored in the general-purpose register 41GR at this time as a random number for internal lottery and stores it in a predetermined area of the RAM 41c. It will be going.

  Note that interrupts to the CPU 41a are prohibited from the extraction of random numbers from the random number generation circuit 42 to the end of processing. This is to prevent the contents of the general-purpose register 41GR from being rewritten in the interrupt processing routine when an interrupt is generated to the CPU 41a.

  Next, stop control of the reels 2L, 2C, 2R will be described.

  The CPU 41a refers to the table index and table creation data stored in the ROM 41b when the reel starts rotating and when the reel stops and the reel that is still rotating still remains. Create a stop control table for each reel. When any of the stop switches 8L, 8C, and 8R corresponding to the rotating reel is effectively detected, the stop control table of the corresponding reel is referred to, and the referred stop control table is drawn. Based on the number of frames, control is performed to stop the rotation of the reels 2L, 2C, 2R corresponding to the operated stop switches 8L, 8C, 8R.

  As shown in FIG. 10, the table index stores the start address of the area in which the data for creating the table is stored for each game state according to the winning status of the combination. Specifically, in the normal gaming state, cherry, bell, replay, big bonus (1) (+ lose), big bonus (1) + cherry, big bonus (1) + bell, big bonus (1) + replay Big Bonus (2) (+ Loss), Big Bonus (2) + Cherry, Big Bonus (2) + Bell, Big Bonus (2) + Replay, Regular Bonus (1) (+ Loss), Regular Bonus (1) For each of + Cherry, Regular Bonus (1) + Bell, Regular Bonus (1) + Replay, Loss, the top address of the area where the data for table creation is stored is stored. Cherry, Bell, JACIN, Regular Bonus (2) (+ Loss), Regular Bona (2) + Cherry, Regular Bonus (2) + For each of Bell and Loss, the top address of the area where the data for table creation is stored is stored. For Regular Bonus, each of Cherry, Bell, JAC and Loss The head address of the area where the table creation data is stored is stored. In addition, even when the gaming state is different or the winning situation of the combination is different, the same control is applied (for example, the same in the cherry winning in the small role game and in the cherry winning in the regular bonus) When applying control, or when applying the same control for Big Bonus (1) + Replay Winning, Big Bonus (2) + Replay Winning, Regular Bonus (1) + Replay Winning, etc.) In this case, the same address is stored as the start address of the area where the table creation data is stored. In such a case, the stop control table is created by referring to the same table creation data. It will be.

  The table creation data is composed of drawn-in frame number data indicating the number of drawn-in frames corresponding to the stop operation position, and an address of drawn-in frame number data to be referred to in accordance with the reel stop status.

  The number-of-drawing frame data referenced according to the reel stop status is whether all reels are rotating, only the left reel is stopped, only the middle reel is stopped, only the right reel is stopped, or left Depending on whether the middle reel is stopped, the left and right reels are stopped, the middle and right reels are stopped, and in the situation where any one of the reels is stopped, Since it may differ depending on the stop position of the stopped reel (in this embodiment, the stop operation position of the stopped reel), the address of the drawing frame number data to be referred to for each of these situations is the rotating reel. It is registered separately, and based on the top address of the table creation data, it is possible to specify the address of the number of frames data to be referred to according to each situation, From a particular address, and to be able to identify the attraction frame number data required for each situation. Even if the reel stop status and the stopped position (stop operation position) of the reel that has been stopped are different, the same address is registered as the address of the drawn frame number data when the same number of drawn frame data is applied. In such a case, the same data for the number of drawn frames is referred to.

  The drawn frame number data is data that can specify the number of drawn frames for each timing at which the stop operation is performed. In this embodiment, stepping motors that make one turn at a cycle of 168 steps (0 to 167) are used for the reel motors 32L, 32C, and 32R. That is, when the reel motors 32L, 32C, and 32R are driven for 168 steps, the reels 2L, 2C, and 2R make one round. As shown in FIG. 11, 42 areas (frames) divided every four steps are defined for one reel, and these areas have area numbers 1 to 42 from the reel reference position. Assigned. On the other hand, the number of symbols arranged on one reel is 21, and symbol numbers 1 to 21 are assigned to the symbols of each reel from the reel reference position. Each of the area numbers 1 to 42 is assigned in order of two. The number of drawn frames by area number is compressed and stored according to a predetermined rule in the number of drawn frames data so that the number of drawn frames by area number can be acquired by expanding the number of drawn frames data. It has become.

  As described above, the stop control table created by referring to the table index and the table creation data as described above corresponds to the area number, and the area corresponding to each area number corresponds to the stop reference position (this In the embodiment, the stop switches 8L, 8C, and 8R are positioned at the timing (the timing at which the number of steps from the reel reference position is included in the range of the number of steps of each region number) positioned in the lower half region in the lower design of the see-through window 3. This is a table in which the number of frames to be drawn in when an operation is detected is set.

  Next, the procedure for creating the stop control table will be described. First, at the start of reel rotation, the top address of the table creation data corresponding to the game state of the game and the winning status of the combination is acquired. Then, the table creation data is specified based on the acquired head address, and the address of the number of frames to be drawn for each reel corresponding to the state in which all the reels are rotating is acquired from the specified table creation data, and the acquired address The drawing frame number data of each reel stored in is developed and a stop control table is created for all reels.

  Also, when any one reel stops or when any two reels stop, the table creation data corresponding to the start address acquired at the start of reel rotation, that is, the game state of the game and the winning status of the combination The table creation data is specified based on the head address of the table, and the stopped reels are drawn from the identified table creation data and the unstopped reels corresponding to the area number (stop operation position) where the stop operation of the reels is performed. The address of the frame number data is acquired, the drawing frame number data of each reel stored at the acquired address is expanded, and a stop control table is created for the unstopped reel.

  Next, when the CPU 41a effectively detects any one of the stop switches 8L, 8C, 8R corresponding to the rotating reel, the control for deriving the display result to the corresponding reel will be described. If any of the stop switches 8L, 8C, and 8R corresponding to the rotating reel is detected effectively, the area number of the stop operation position is based on the number of steps from the reel reference position when the stop operation is detected. And the number of drawn frames corresponding to the area number of the specified stop operation position is acquired by referring to the stop control table of the reel where the stop operation is detected. Then, control is performed to rotate and stop the reel by the number of acquired frames. Specifically, from the number of steps from the reel reference position at the time when the stop operation is detected, the number of steps from the acquired number of drawn frames until it is stopped is calculated, and the reel is rotated and stopped by the calculated number of steps. Take control. As a result, an area (stop point in the figure) corresponding to the area number corresponding to the stop position ahead of the number of frames to be drawn in from the area (stop operation point in the figure) corresponding to the area number of the stop operation position where the stop operation is detected. It will stop at the stop reference position (in this embodiment, the lower half region in the lower symbol of the see-through window 3).

  Further, the table index of this embodiment stores only one address as the top address of the table creation data storage area corresponding to the winning situation of one role in one gaming state. In the table creation data, only one address is stored as the address of the storage area for the number of drawn frame data corresponding to the stop status of one reel (and the stop operation position of the stopped reel). That is, the table creation data corresponding to the winning status of each combination for each gaming state, and the number-of-drawing frame data corresponding to the reel stop status (and the stop operation position of the stopped reel) are uniquely determined. The stop control table created with reference to these is also unique for the winning combination status and the reel stop status (and the stop operation position of the stopped reel) for each gaming state. For this reason, when all of the gaming state, winning combination status, and reel stop status (and stop operation position of a stopped reel) are the same, the same stop control table, that is, the same control pattern is used. Thus, reel stop control is performed.

  Further, in this embodiment, a value of 0 to 9 is determined as the number of drawn frames, and it is possible to stop the reel by drawing a maximum of nine symbols after detecting a stop operation. In other words, the symbol stop position can be designated from a range of up to 10 frames including the stop operation position at which the stop operation is detected. In addition, since it is necessary to move two frames to move the reel for one symbol, it is possible to stop the reel by pulling up to four symbols after detecting the stop operation, and stop when the stop operation is detected. The symbol stop position can be designated from a range of up to five symbols including the operation position.

  In this embodiment, when an area with an odd area number is stopped at the reference stop position, the design will stop with a half frame shift from the winning line. In order for the area to stop at the reference stop position, an odd number is always set for the number of drawn frames corresponding to an odd area number, and an even number is always set for the number of drawn frames corresponding to an even area number. It has been established. That is, as the number of frames to be drawn corresponding to each area number, a value at which the symbol always stops at the upper, middle, and lower positions of the see-through window 3 is determined.

  In addition, the table index stores the address of the data for table creation in which the number of frames to be drawn is determined so that the combination of the winning combinations is drawn to the maximum within the range of 9 frames when any of the roles is won. If no winning combination is won, an address of data for table creation in which the number of frames to be drawn is determined so that no combination of any winning combinations is stored. For this reason, when any of the winning combinations is won, a stop control table in which the number of frames to be drawn is determined so that the combination of winning combinations is drawn within a range of 9 frames is created, and the reel stop control is performed. On the other hand, if none of the winning combinations is won, a stop control table in which the number of drawn frames that do not have any combination of the winning combinations is created, and reel stop control is performed. As a result, when the stop operation is performed, if the symbols of the winning combination can be stopped on the winning line within the draw range of 9 frames, the control is performed to align and stop the winning combination. The symbol of the role that is not performed is controlled to be stopped in the drawing range of 9 frames.

  Here, as shown in FIG. 2, “bell”, “replay”, and “JAC” are all arranged within 5 symbols, that is, within 10 frames, for each of the reels 2L, 2C, and 2R. It can be stopped at any position within the 9-frame pull-in range. In other words, when the winning flags of bell, replay, JAC, and JACIN are set, the winning combination can always be won regardless of the operation timing of the stop switches 8L, 8C, and 8R by the player.

  Next, the chance eyes will be described. In this embodiment, a chance is a case where any bonus (Big Bonus (1) (2), Regular Bonus (1)) is won in the normal gaming state, and no role is won. In this embodiment, “watermelon-watermelon-watermelon”, “watermelon-watermelon-7” and “watermelon-watermelon-BAR” are displayed on the winning line. Apply as eyes. In the present embodiment, since chance chances are not determined as roles, no medal payout or game state transition is involved.

  Also, in this embodiment, when any bonus is won in the normal gaming state and no other combination is won, and when no combination is won in the normal gaming state, It is possible to stop on condition that each reel has been stopped in the middle and right order, and control is performed so that chances are not derived when stop operations are performed in other order. Is done.

  Here, the reel stop control when the chance is derived will be described with reference to FIGS.

  FIGS. 11 to 13 show that when one of the bonuses is won in the normal gaming state and the other combination is not won (Big Bonus (1) + Loss, Big Bonus (2) + Loss, Regular Bonus) It is a figure which shows the stop control table created when (1) + losing) and any combination is not won (losing).

  First, in a case where no combination is won in the normal gaming state (losing), a stop control table corresponding to the item of losing in FIG. Is done. In this stop control table, 0 and 1 are determined as the number of frames to be drawn in the area numbers 16 and 17, respectively. When a stop operation of the left reel is detected at these timings, the number 8 “watermelon” The symbol stops at the bottom. In addition, 0 to 5 are determined as the number of frames to be drawn in the area numbers 18 to 23, respectively, and when the left reel stop operation is detected at these timings, the “Watermelon” symbol of No. 8 stops in the middle. To do. In the normal gaming state, when neither of the winning combinations is won (losing), the stop operation of the left reel is detected at the timing of the area numbers 16 and 17, and the “Watermelon” symbol of No. 8 is displayed at the bottom. When the stop operation of the left reel is detected at the timing of the area numbers 18 to 23, the “Watermelon” symbol of No. 8 stops in the middle stage, but among these, the left reel at the timing of the area number 17 No. 8 “Watermelon” symbol stops at the lower stage by detecting the stop operation of No. 8, or No. 8 “Watermelon” by detecting the stop operation of the left reel at the timing of the area numbers 19, 21, 23 On the condition that the symbol has stopped in the middle, a stop control table capable of finally stopping the chance eye is created as a stop control table for the middle and right reels. Even if the “watermelon” symbol stops at the lower or middle level, if it stops when the stop operation of the left reel is detected at the timing of the area numbers 16, 18, 20, and 22, the final chance Never stop. In this embodiment, when a stop operation of the left reel is detected at the timings of the area numbers 16, 18, 20, and 22, a stop control table in which the “watermelon” symbol does not stop as a middle reel stop control table. However, for example, a stop control table in which the “watermelon” symbol stops at the middle stage is created as a middle reel stop control table. When the “watermelon” symbol stops in the middle, the “watermelon” symbol “BAR” “7” symbol does not stop on the winning line where the “watermelon” symbol is tempered as a stop control table for the right reel By creating it, it is possible to finally prevent the chance eye from stopping.

  Next, when the stop operation of the left reel is detected at the timing of the region numbers 17, 19, 21, and 23, when the eighth “watermelon” symbol stops at the lower or middle stage of the left reel, the middle reel stop control is performed. As the table, a stop control table corresponding to the items of the lost and left region numbers 17, 19, 21, and 23 in FIG. 12 is created. In this stop control table, when a stop operation of the middle reel is detected at the timings of the area numbers 4 and 5, the “watermelon” symbol of No. 1 stops at the middle stage, and at the timing of the area numbers 12 and 13, the middle reel When a stop operation is detected, the “Watermelon” symbol of No. 5 stops in the middle stage, and when a stop operation of the middle reel is detected at the timing of the area numbers 20, 21, and 23, the “Watermelon” of No. 9 When the symbol stops in the middle stage and the stop operation of the middle reel is detected at the timing of the area numbers 34 to 37, the “watermelon” symbol of No. 16 stops at the middle stage and at the timing of the area numbers 38, 39, and 41. When the stop operation of the middle reel is detected, the 18th “watermelon” symbol stops at the middle stage. If none of the roles is won in the normal gaming state (losing), the middle reel stop operation is detected by detecting the middle reel stop operation at the timing of area number 23. As a stop control table for the right reel, the stop control table for the right reel is finally obtained on condition that the “watermelon” symbol No. 18 has stopped in the middle stage when the stop operation of the middle reel is detected at the timing of area number 41. A stop control table capable of stopping chances is created, and even if the “Watermelon” symbol of No. 9 or the “Watermelon” of No. 18 stops in the middle, the region numbers 23 and 41 If a stop operation is detected when a middle reel stop operation is detected at a time other than the above timing, the winning reel with the “watermelon” symbol is used as the stop control table for the right reel. Symbol "watermelon", "BAR", "7" is not stopped on the emissions are adapted to stop control table is created, ultimately chances eyes will not be stopped.

  Next, when the stop operation of the left reel is detected at the timing of the area number 17, the “watermelon” symbol of No. 8 stops at the lower stage of the left reel, and the stop operation of the middle reel at the timing of the area number 23 or 41 Is detected, the 9th or 18th “watermelon” symbol stops in the middle stage of the middle reel, and the “watermelon” symbol is tempered on the left, middle reel winning line L5 (winning line L5). If any of the symbols “watermelon”, “BAR”, and “7” stops, it will be a chance), as the stop control table on the left side of FIG. Loss, left-middle area numbers 17-23, 17-41, BB (1) (2) Loss, RB loss, left-middle stop symbol: A stop control table corresponding to the item of the watermelon rising upward template is created. . In this stop control table, when the stop operation of the right reel is detected at the timing of the area numbers 2 to 9, the “watermelon” symbol of No. 20 stops at the upper stage, and at the timing of the area numbers 10 to 19 When the stop operation is detected, the “Watermelon” symbol of No. 3 stops at the upper stage, and when the stop operation of the right reel is detected at the timing of the area numbers 20 to 25, the “BAR” symbol of No. 7 is When the stop operation of the right reel is detected at the timing of the area numbers 26 to 35, the 11th “watermelon” symbol stops at the upper stage, and the right reel at the timing of the area numbers 36 to 42, 1 When the stop operation is detected, the “7” symbol of No. 16 stops in the upper stage. That is, in this stop control table, the symbol “watermelon”, “BAR”, or “7” always stops at the upper stage of the right reel regardless of the timing of the stop operation of the right reel.

  In addition, the stop operation of the left reel is detected at the timing of the area numbers 19, 21, 23, the “watermelon” symbol of No. 8 stops in the middle stage of the left reel, and the stop of the middle reel at the timing of the area numbers 23 or 41 When the operation is detected, the 9th or 18th “watermelon” symbol stops in the middle stage of the middle reel, and the “watermelon” symbol is on the left, middle reel winning line L1 (winning line) When one of the symbols “watermelon”, “BAR”, and “7” stops on L1, there is a chance, the stop control table on the right side of FIG. That is, lose, left-middle area numbers 19, 21, 23-23, 19, 21, 23-41, BB (1) (2) lose, RB lose, left-middle stop symbol: corresponding to the item of watermelon middle stage pie Stop Your table is created. In this stop control table, when the stop operation of the right reel is detected at the timings of the region numbers 24 to 33, the “watermelon” symbol of No. 11 stops in the middle. That is, in this stop control table, “watermelon” stops at the middle stage of the right reel on condition that the stop operation of the right reel is performed at a timing at which the No. 11 “watermelon” symbol can be drawn, and at other timings , “Watermelon”, “BAR” or “7” does not stop in the middle.

  Next, when the big bonus (1) is won in the normal gaming state and the other combination is not won (big bonus (1) + lose), the left reel is stopped at the start of the reel rotation. As the control table, a stop control table corresponding to the item BB (1) loss in FIG. 11 is created. In this stop control table, when the stop operation of the left reel is detected at the timing of the area numbers 16 and 17, the “Watermelon” symbol of No. 8 stops at the lower stage, and the timing of the left reel at the timing of the area numbers 18 to 27 When a stop operation is detected, the 8th “watermelon” symbol stops in the middle. In the normal gaming state, when the big bonus (1) is won and the other combination is not won (big bonus (1) + lose), the left reel is stopped at the timing of area numbers 16 to 23. Is detected, the No. 8 “Watermelon” symbol stops at the lower or middle stage, and among these, the No. 8 “Watermelon” symbol is displayed regardless of the timing of the left reel. Stop control that can finally stop the chance as a stop control table for the middle and right reels, provided that the symbol stops at the lower stage or the No. 8 "watermelon" symbol stops at the middle stage A table is created.

  Next, when the stop operation of the left reel is detected at the timing of the area numbers 16 and 17, and when the “Watermelon” symbol of No. 8 stops in the lower stage of the left reel, the stop control table of FIG. A stop control table corresponding to the items of BB (1) loss and left region numbers 16 and 17 is created. In this stop control table, when the stop operation of the middle reel is detected at the timing of the area numbers 4 to 7, the first “watermelon” symbol stops at the middle stage, and the timing of the middle reel is reached at the timing of the area numbers 26 to 29. When the stop operation is detected, the 9th “watermelon” symbol stops in the middle, and when the middle reel stop operation is detected at the timing of the area numbers 34 to 37, the 16th “watermelon” symbol is displayed. When a middle reel stop operation is detected at the timing of area numbers 38 to 42 and 1 to 3, the 18th “watermelon” symbol stops at the middle stage. When the big bonus (1) is won in the normal gaming state and the other combination is not won (big bonus (1) + losing), the region numbers 4-7, 26-29, 34-42 When the middle reel stop operation is detected at the timings 1 to 3, the “watermelon” symbol is stopped at the middle stage, and it is related to which region number timing of the middle reel stop operation is detected. First, on the condition that the “watermelon” symbol has stopped in the middle, a stop control table capable of finally stopping the chance eye is created as the stop control table for the right reel.

  Further, when the stop operation of the left reel is detected at the timing of the area numbers 18 to 27, when the “watermelon” symbol of No. 8 stops in the middle stage of the left reel, the stop control table of FIG. A stop control table corresponding to the items of BB (1) loss and left region numbers 18 to 27 is created. In this stop control table, when the stop operation of the middle reel is detected at the timing of the area numbers 4 to 7, the “watermelon” symbol of No. 1 stops at the middle stage, and the timing of the middle reel at the timing of the area numbers 28 and 29 When the stop operation is detected, the 9th “watermelon” symbol stops in the middle, and when the middle reel stop operation is detected at the timing of the area numbers 34 to 37, the 16th “watermelon” symbol is displayed. When a middle reel stop operation is detected at the timing of area numbers 38 to 42 and 1 to 3, the 18th “watermelon” symbol stops at the middle stage. In the normal gaming state, when the big bonus (1) is won and the other combination is not won (big bonus (1) + losing), the area numbers 4-7, 28, 29, 34-42 When the middle reel stop operation is detected at the timings 1 to 3, the “watermelon” symbol is stopped at the middle stage, and it is related to which region number timing of the middle reel stop operation is detected. First, on the condition that the “watermelon” symbol has stopped in the middle, a stop control table capable of finally stopping the chance eye is created as the stop control table for the right reel.

  Next, when the stop operation of the left reel is detected at the timing of the region numbers 16 and 17, the “Watermelon” symbol of No. 8 is stopped at the lower stage of the left reel, and 4 to 7, 26 to 29, and 34 to 42 are stopped. When the middle reel stop operation is detected at the timings 1 to 3, the “watermelon” symbol stops at the middle stage of the middle reel, and the “watermelon” symbol appears on the left, middle reel winning line L5. When the symbol “watermelon”, “BAR”, or “7” stops on the winning line L5, it becomes a chance, and the left reel of FIG. 13 is used as a stop control table for the right reel. Stop control table, ie, lost, left-middle region numbers 17-23, 17-41, BB (1) (2) lost, RB lost, left-middle stop symbol: stop control corresponding to the item of watermelon rising to the right Table created It is. In the stop control table, as described above, the symbol “watermelon”, “BAR”, or “7” always stops at the upper stage of the right reel regardless of the timing of the right reel stop operation.

  In addition, the stop operation of the left reel is detected at the timing of the area numbers 18 to 27, the “Watermelon” symbol of No. 8 stops in the middle stage of the left reel, and the area numbers 4 to 7, 28, 29, 34 to 42, When the stop operation of the middle reel is detected at the timing of 1 to 3, the “watermelon” symbol stops in the middle stage of the middle reel, and the “watermelon” symbol is tempered on the left, middle reel winning line L1. Time (when one of the symbols “watermelon”, “BAR”, “7” stops on the winning line L1 is a chance), the right reel in FIG. Stop control table, that is, lost, left-middle region numbers 19, 21, 23-23, 19, 21, 23-41, BB (1) (2) lost, RB lost, left-middle stop Stop corresponding to the item Your table is created. In this stop control table, “watermelon” stops in the middle of the right reel, provided that the stop operation of the right reel is performed at the timing at which the 11th “watermelon” symbol can be pulled in as described above. At this timing, any of the symbols “watermelon”, “BAR” or “7” does not stop at the middle stage.

  Next, in the normal gaming state, when the big bonus (2) or the regular bonus (1) is won and the other role is not won (the big bonus (2) + losing or the regular bonus (1) + At the time of the start of reel rotation, a stop control table corresponding to the items BB (2) loss and RB loss in FIG. 11 is created as the stop control table for the left reel. In this stop control table, when the stop operation of the left reel is detected at the timing of the area numbers 22 to 25, the “Watermelon” symbol of No. 8 stops at the lower stage, and the timing of the left reel at the timing of the area numbers 26 and 27 When a stop operation is detected, the 8th “watermelon” symbol stops in the middle. In the normal gaming state, if you win the Big Bonus (2) or Regular Bonus (1) and you have not won any other role (Big Bonus (2) + Loss or Regular Bonus (1) + Loss) When the stop operation of the left reel is detected at the timing of the area numbers 22 to 27, the “Watermelon” symbol of No. 8 stops at the lower or middle stage, and among these, the stop of the left reel is performed at the timing of which area number Regardless of whether or not an operation has been detected, the stop control table for the middle and right reels, on condition that the number 8 “watermelon” symbol stops at the bottom or the number 8 “watermelon” symbol stops at the middle, A stop control table capable of finally stopping the chance is created.

  Next, when the stop operation of the left reel is detected at the timing of the area numbers 22 to 27, when the “watermelon” symbol of No. 8 stops at the lower or middle stage of the left reel, A stop control table corresponding to the items of 12 BB (1) loses, RB loses, and left region numbers 22 to 27 is created. In the stop control table, when the stop operation of the middle reel is detected at the timing of the area numbers 4 to 11, the “watermelon” symbol of No. 1 stops at the middle stage, and the timing of the middle reel at the timing of the area numbers 12 to 19 When a stop operation is detected, the “Watermelon” symbol of No. 5 stops in the middle stage, and when a stop operation of the middle reel is detected at the timing of the area numbers 20 to 29, the “Watermelon” symbol of No. 9 is displayed. When the middle reel stops and the middle reel stop operation is detected at the timing of area numbers 34 to 37, the 16th “watermelon” symbol stops at the middle stage and at the timing of area numbers 38 to 42, 1 to 3. When the stop operation of the middle reel is detected, the 18th “watermelon” symbol stops at the middle stage. In the normal gaming state, if you win the Big Bonus (2) or Regular Bonus (1) and you have not won any other role (Big Bonus (2) + Loss, Regular Bonus (1) + Loss) , When the stop operation of the middle reel is detected at the timing of the area numbers 4 to 29, 34 to 42, 1 to 3, that is, the timings other than the area numbers 30 to 33, the “watermelon” symbol stops at the middle stage. Regardless of the region number timing at which the middle reel stop operation is detected, the chances of the right reel as a stop control table are finally determined on the condition that the “watermelon” symbol has stopped in the middle. A stop control table that can be stopped is created.

  Next, when the stop operation of the left reel is detected at the timing of the area numbers 22 to 25, the “Watermelon” symbol of No. 8 stops at the lower stage of the left reel, and the middle reel at a timing other than the area numbers 30 to 33 Is detected, the “watermelon” symbol is stopped at the middle stage of the middle reel, and the “watermelon” symbol is tempered on the winning line L5 of the left and middle reels (“ When one of the symbols “watermelon”, “BAR”, and “7” stops, it becomes a chance)), the stop control table on the left side of FIG. -Middle area numbers 17-23, 17-41, BB (1) (2) Loss, RB loss, left-middle stop symbol: A stop control table corresponding to the item of watermelon rising upward temper is created. In the stop control table, as described above, the symbol “watermelon”, “BAR”, or “7” always stops at the upper stage of the right reel regardless of the timing of the right reel stop operation.

  In addition, the stop operation of the left reel is detected at the timing of the area numbers 26 and 27, the “watermelon” symbol of No. 8 stops at the middle stage of the left reel, and the stop operation of the middle reel at the timing other than the area numbers 30 to 33 Is detected, the “watermelon” symbol stops in the middle stage of the middle reel, and when the “watermelon” symbol is tempered on the left, middle reel winning line L1 (“watermelon” on the winning line L1, When one of the symbols “BAR” and “7” stops, it becomes a chance), as the right reel stop control table, the stop control table on the right side of FIG. No. 19.21.23-23, 19.21.23-41, BB (1) (2) Loss, RB loss, left-medium stop symbol: a stop control table corresponding to the item of watermelon middle stage temper is created.In this stop control table, “watermelon” stops in the middle of the right reel, provided that the stop operation of the right reel is performed at the timing at which the 11th “watermelon” symbol can be pulled in as described above. At this timing, any of the symbols “watermelon”, “BAR” or “7” does not stop at the middle stage.

  As described above, when no winning combination is won in the normal gaming state (losing), the reels are stopped in the order of left, middle, and right, and the left reel is processed at the timing of area number 17. Stop operation is performed at the timing of the area number 23 or 41, or the operation of stopping the left reel is performed at the timing of the area numbers 19, 21, 23, and the area number 23 or “Watermelon-Watermelon-Watermelon”, “Watermelon-Watermelon-BAR” are provided on the condition that the operation of stopping the middle reel is performed at the timing of 41 and the operation of stopping the right reel is performed at the timing of the area numbers 24-33. ”Or“ Watermelon-Watermelon-7 ”stops on the winning line, and the chance is derived as a display result.

  The probability that the stop operation of the left reel is performed at the timing of the area number 17, the stop operation of the middle reel is performed at the timing of the area number 23 or 41, and the stop operation of the right reel is performed at any timing is 1 / 882 (1/42 × 2/42 × 42/42), the left reel is stopped at the timing of the area numbers 19, 21, and 23, and the middle reel is stopped at the timing of the area numbers 23 or 41 The probability that the operation is performed and the right reel stop operation is performed at the timing of the region numbers 24 to 33 is 1 / 11234.8 (3/42 × 2/42 × 10/42). For this reason, the probability that a chance eye is derived in the case of not winning any combination in the normal gaming state (losing) is 1 / 514.5 (1/882 + 1 / 1234.8).

  In addition, the “watermelon” symbol on the left reel stops at the lower or middle level when the left reel is stopped at the timing of area numbers 16 to 23, so the “watermelon” symbol stops at the lower or middle level of the left reel. The probability of playing is 1 / 5.25 (8/42), but the chance is finally derived on the condition that the stop operation of the left reel is performed at the timing of the area numbers 17, 19, 21, and 23. Therefore, the probability that the “watermelon” symbol stops at the lower or middle of the left reel by performing the stop operation of the left reel at a timing satisfying the chance derivation condition is 1 / 10.5 (4 / 42). In addition, when the left reel is stopped at the timing of the region numbers 17, 19, 21, and 23, which are the conditions for deriving the chance eye, and the “watermelon” symbol stops in the lower or middle stage, the region numbers 4, 5, Since the “watermelon” symbol is stopped at the middle stage when the stop operation of the middle reel is performed at the timing of 12, 13, 20, 21, 23, 34 to 39, 41, the timing of the region numbers 17, 19, 21, 23 In the state where the stop operation of the left reel is performed and the “watermelon” symbol is stopped at the lower or middle stage, the probability that the “watermelon” symbol stops at the middle stage of the middle reel and the chance eyes are on the winning line is 3 (14/42), but the chance chance is finally derived on the condition that the operation of stopping the middle reel is performed at the timing of the area numbers 23 and 41. "Watermelon" symbol is stopped in the middle of the reel by the reel stop operation is performed at satisfying timing, the probability of chance th to Tenpai on the pay line becomes 1/21 (2/42).

  In addition, the “watermelon” symbol on the left reel stops at the lower or middle level when the left reel is stopped at the timing of area numbers 16 to 23, so the “watermelon” symbol stops at the lower or middle level of the left reel. The average number of drawn frames (the total number of drawn frames for each area number / number of area numbers) is 2 (16/8), but the left reel stops at the timing of area numbers 17, 19, 21, and 23. Since the chance chance is finally derived on the condition that the operation has been performed, the average number of frames to be drawn in the left reel when the chance eye is derived is 2.5 (10/4). . In addition, when the stop operation of the left reel is performed at the timing of the area numbers 17, 19, 21, and 23 which are the derivation conditions for the chance eye, and the “watermelon” symbol stops at the lower or middle stage of the left reel, the area number 1 Since the middle reel is stopped at the timing of ~ 15, 20-27, 34-42, the "watermelon" symbol stops at the middle stage of the middle reel, and the chance is on the winning line. The average number of frames to be drawn is 1.14 (16/14), but the chance is finally derived on the condition that the middle reel has been stopped at the timings of the area numbers 23 and 41. Therefore, the average number of frames drawn on the middle reel when the chance is derived is 3 (6/2).

  Further, in the case of not winning any combination in the normal gaming state (losing), the left reel stop operation is detected at the timing of area number 17 by detecting the stop operation of the left reel at the timing of area number 16. As in the case where the operation is detected, the number 8 “watermelon” symbol stops at the lower stage, and when the stop operation of the left reel is detected at the timing of the region numbers 18, 20, 22, the region numbers 19, 21, As in the case where the stop operation of the left reel is detected at the timing of 23, the “Watermelon” symbol of No. 8 stops in the middle stage, but when the stop operation of the left reel is detected at the timing of the area number 17, the No. 8 The "watermelon" symbol of No. 8 stops at the lower stage, or when the stop operation of the left reel is detected at the timing of area numbers 19, 21, and 23, the No. 8 "watermelon" symbol stops at the middle stage As the final display result, chances are derived, so when the “watermelon” number 8 stops at the lower or middle of the left reel, that is, when the left reel is stopped, Even if the stop position is the same as the stop position from which the chance eyes are finally derived, the chance eyes may not be finally derived due to the different stop operation positions.

  Further, when the stop operation of the left reel is detected at the timing of the area numbers 17, 19, 21, 23, and the “watermelon” symbol of No. 8 stops at the lower or middle stage, the area numbers 20-22, 24- When the middle reel stop operation is detected at timing 27, the 9th “watermelon” symbol stops at the middle stage in the same manner as when the middle reel stop operation is detected at timing area number 23. By detecting the middle reel stop operation at the timing of 38 to 40, 42, and 1 to 3, the 18th “watermelon” symbol is the same as when the middle reel stop operation is detected at the timing of the region number 41. Stops at the middle stage, but when the stop operation of the middle reel is detected at the timing of area number 23, the 9th “watermelon” symbol stops at the middle stage, or the operation of stopping the middle reel at the timing of area number 41 As a result of the detection, chances are derived as the final display result on the condition that the 18th “watermelon” symbol has stopped in the middle stage. When the "watermelon" symbol of Fig. 9 stops and the 9th or 18th "watermelon" symbol stops in the middle of the middle reel, that is, when the left reel and middle reel are stopped, the stop position of the left reel and middle reel is Even if it is the same as the stop position where the chance chance is finally derived, the chance chance may not be finally derived.

  On the other hand, when the big bonus (1) is won in the normal gaming state and other roles are not won (Big Bonus (1) + Loss), the reels are stopped in the order of left, middle and right. As the operation is performed, the left reel is stopped at the timing of the area numbers 16 and 17, and the middle reel is stopped at the timing of the area numbers 4 to 7, 26 to 29, 34 to 42, and 1 to 3. Left reel stop operation is performed at the timing of area numbers 18 to 27, and middle reel stop operation is performed at the timing of area numbers 4 to 7, 28, 29, 34 to 42, and 1 to 3. And any one of “watermelon-watermelon-watermelon”, “watermelon-watermelon-BAR”, and “watermelon-watermelon-7” on the condition that the stop operation of the right reel is performed at the timing of the area numbers 24 to 33 of Seen together is stopped on the winning line, chance eyes is derived as a result display.

  The stop operation of the left reel is performed at the timing of the region numbers 16 and 17, and the stop operation of the middle reel is performed at the timing of the region numbers 4 to 7, 26 to 29, 34 to 42, and 1 to 3, and either The probability that the right reel stop operation will be performed at the timing of 1/44 (2/42 × 20/42 × 42/42), and the left reel stop operation will be performed at the timing of area numbers 18 to 27. In addition, there is a probability that the middle reel stop operation is performed at the timings of the region numbers 4 to 7, 28, 29, 34 to 42, and 1-3, and the right reel stop operation is performed at the timings of the region numbers 24 to 33. 1 / 41.16 (10/42 × 18/42 × 10/42). For this reason, in the normal gaming state, when the big bonus (1) is won and the other combination is not won (big bonus (1) + losing), the probability that the chance eye is derived is 1/21. 29 (1 / 44.1 + 1 / 41.16).

  In addition, the “watermelon” symbol on the left reel stops at the lower or middle level when the left reel is stopped at the timing of area numbers 16 to 27, so the “watermelon” symbol stops at the lower or middle level of the left reel. The probability of doing is 1 / 3.5 (12/42). In addition, when the “watermelon” symbol stops in the lower stage of the left reel, the “watermelon” symbol is displayed in the middle stage by performing the stop operation of the middle reel at the timing of the area numbers 1 to 7, 26 to 29, and 34 to 42. Since the “watermelon” symbol is stopped at the lower stage of the left reel, the “watermelon” symbol is stopped at the middle stage of the middle reel, and the probability that the chance eye is tempered on the winning line is 1 / 2.1 (20 / 42). In addition, when the “watermelon” symbol stops in the middle of the left reel, the “watermelon” symbol is displayed in the middle by performing the stop operation of the middle reel at the timing of the area numbers 1 to 7, 28, 29, and 34 to 42. Since it stops, the probability that the “watermelon” symbol stops in the middle stage of the middle reel while the “watermelon” symbol stops in the middle stage of the left reel, and the chance of the tempering on the winning line is 1 / 2.33 (18 / 42).

  In addition, the “watermelon” symbol on the left reel stops at the lower or middle level when the left reel is stopped at the timing of area numbers 16 to 27, so the “watermelon” symbol stops at the lower or middle level of the left reel. The average number of frames drawn in, that is, the average number of frames drawn in the left reel when a chance is derived is 3.83 (46/12). In addition, when the “watermelon” symbol stops in the lower stage of the left reel, the “watermelon” symbol is displayed in the middle stage by performing the stop operation of the middle reel at the timing of the area numbers 1 to 7, 26 to 29, and 34 to 42. Since the “watermelon” symbol is stopped at the lower row of the left reel, the “watermelon” symbol is stopped at the middle row of the middle reel, and the average number of frames to be drawn when the chance eyes are tempered on the winning line, that is, left When the chance chance is derived in a state where the “watermelon” symbol is stopped at the lower stage of the reel, the average number of frames drawn in the middle reel is 3.5 (70/20). In addition, when the “watermelon” symbol stops in the middle of the left reel, the “watermelon” symbol is displayed in the middle by performing the stop operation of the middle reel at the timing of the area numbers 1 to 7, 28, 29, and 34 to 42. Since it stops, the “watermelon” symbol stops in the middle of the left reel, the “watermelon” symbol stops in the middle of the middle reel, and the average number of draws when the chance is tempered on the winning line, that is, The average number of frames drawn on the middle reel when the “watermelon” symbol is stopped in the middle of the left reel and the chance reel is derived is 3.17 (57/18).

  Also, in the normal gaming state, when the big bonus (2) or regular bonus (1) is won and no other role is won (Big Bonus (2) + Loss or Regular Bonus (1) + Loss) In this case, the reels are stopped in the order of left, middle, and right, the left reel is stopped at the timing of the area numbers 22 to 25, and the middle reel is operated at timings other than the area numbers 30 to 33. A stop operation is performed, or a stop operation of the left reel is performed at the timing of the area numbers 26 and 27, and a stop operation of the middle reel is performed at a timing other than the area numbers 30 to 33, and the area numbers 24 to 33 are "Watermelon-Watermelon-Watermelon", "Watermelon-Watermelon-BAR", "Watermelon-Watermelon" Any combination of -7 "is stopped on the winning line, chance eyes is derived as a result display.

  The stop operation of the left reel is performed at the timing of the area numbers 22 to 25, the stop operation of the middle reel is performed at the timing other than the area numbers 30 to 33, and the stop operation of the right reel is performed at any timing. The probability is 1 / 1.61 (4/42 × 38/42 × 42/42), the left reel is stopped at the timing of the region numbers 26 and 27, and at timings other than the region numbers 30 to 33 The probability that the middle reel stop operation is performed and the right reel stop operation is performed at the timing of the region numbers 24 to 33 is 1 / 97.48 (2/42 × 38/42 × 10/42). For this reason, in the normal gaming state, when the big bonus (2) or regular bonus (1) is won and no other role is won (big bonus (2) + lose or regular bonus (1) + lose ) Is a probability of deriving a chance eye is 1 / 1.37 (1 / 11.61 + 1 / 97.48).

  In addition, the “watermelon” symbol on the left reel stops at the lower or middle level when the left reel is stopped at the timing of area numbers 22 to 27, so the “watermelon” symbol stops at the lower or middle level of the left reel. The probability of doing is 1/7 (6/42). In addition, when the “watermelon” symbol is stopped at the lower or middle stage of the left reel, the “watermelon” symbol is stopped at the middle stage by performing the stop operation of the middle reel at the timings of the area numbers 1 to 29 and 34 to 42. Therefore, the probability that the “watermelon” symbol stops in the middle stage of the middle reel while the “watermelon” symbol stops in the lower or middle stage of the left reel, and the chance eye is tempered on the winning line is 1 / 1.11 (38 / 42).

  In addition, the “watermelon” symbol on the left reel stops at the lower or middle level when the left reel is stopped at the timing of area numbers 22 to 27, so the “watermelon” symbol stops at the lower or middle level of the left reel. The average number of frames drawn in, that is, the average number of frames drawn in the left reel when a chance is derived is 7.83 (47/6). In addition, when the “watermelon” symbol is stopped at the lower or middle stage of the left reel, the “watermelon” symbol is stopped at the middle stage by performing the stop operation of the middle reel at the timings of the area numbers 1 to 29 and 34 to 42. So, when the “watermelon” symbol is stopped at the lower or middle of the left reel, the “watermelon” symbol stops at the middle of the middle reel, and the average number of frames to be drawn when the chance eyes are tempered on the winning line, that is, the left When the chances are derived with the “watermelon” symbol stopped at the lower or middle stage of the reel, the average number of frames to be drawn in the middle reel is 3.55 (135/38).

  As described above, in this embodiment, the probability that a chance eye is derived is 1 / 514.5 when none of the roles is won (losing) in the normal gaming state, and the big bonus (1) in the normal gaming state. If the player has been won and the other role has not been won (Big Bonus (1) + Loss), the probability that the chance will be derived will be 1 / 21.29, and the Big Bonus (2) in the normal gaming state Or if the regular bonus (1) is won and no other role is won (Big Bonus (2) + Loss or Regular Bonus (1) + Loss), the probability that the chance is derived is 1 / 10.37. In other words, chances are higher when you win one of the bonuses in the normal gaming state and do not win any other role than when you do not win any of the roles in the normal gaming state. The eyes are derived.

  In addition, if none of the roles is won in the normal gaming state (losing), the probability that the “watermelon” symbol will stop in the middle or lower part of the left reel is 1 / 5.25, which is a big difference in the normal gaming state. If the bonus (1) has been won and no other role has been won (Big Bonus (1) + Loss), the probability that the “watermelon” symbol will stop in the middle or lower part of the left reel is 1 / 3.5. In other words, it is more probable that the player has won the big bonus (1) in the normal gaming state and has not won the other role than the player who has not won in any normal role. The "watermelon" symbol that constitutes the chance eye is derived on the left reel.

  In addition, in the normal gaming state, when any of the roles is not won (losing), the left reel is stopped at the timing that satisfies the derivation condition of the chance, so that “watermelon” The probability that the symbol will stop will be 1 / 10.5, and if the player wins the Big Bonus (2) or Regular Bonus (1) in the normal gaming state and does not win any other role (Big Bonus (2 ) + Loss or Regular Bonus (1) + Loss), the probability that the “watermelon” symbol stops at the lower or middle of the left reel is 1/7 (6/42). In other words, the probability that the “watermelon” symbol constituting the chance eye is derived by performing the stop operation of the left reel at the timing that satisfies the chance eye derivation condition is not won in any role in the normal gaming state. It will be higher if you win one of the bonuses in the normal gaming state and not win another role.

  In addition, when none of the winning combinations is won in the normal gaming state (losing), the operation of stopping the left reel is performed at the timing of the area numbers 17, 19, 21, and 23, which are the derivation conditions for the chances. If the “watermelon” symbol stops at the lower or middle level, the “watermelon” symbol stops at the middle level of the middle reel, and the chance that the chance will be tempered on the winning line is 1/3. In case of winning 1) and not winning other roles (Big Bonus (1) + Loss), if the “watermelon” symbol stops at the lower or middle of the left reel, The probability that the “watermelon” symbol stops in the middle and the chance will be tempered on the winning line is 1 / 2.1, which is a big bonus (2) or regulation in the normal gaming state -If you have won the bonus (1) and have not won any other role (Big Bonus (2) + Loss or Regular Bonus (1) + Loss) When the symbol stops, the probability that the “watermelon” symbol stops at the middle stage of the middle reel and the chance eye is tempered on the winning line is 1 / 1.11. In other words, when the chance eyes stop on the left reel and the middle reel, the probability that the chance eyes are tempered on the winning line is higher in the normal gaming state than in the case where no role is won in the normal gaming state. It is higher if you have won the bonus and have not won other roles.

  In addition, in the normal game state, when any of the roles is not won (losing), the average number of frames drawn when the “watermelon” symbol stops at the lower or middle of the left reel is 2, and the chance When the left reel is stopped at a timing satisfying the derivation condition, the average number of frames to be drawn when the “watermelon” symbol stops at the lower or middle of the left reel is 2.5. In addition, when the big bonus (1) is won in the normal gaming state and other roles are not won (Big Bonus (1) + Loss), the “Watermelon” symbol is displayed at the lower or middle of the left reel. The average number of draws at the time of stopping is 3.83. In the normal gaming state, when winning the big bonus (2) or regular bonus (1) and not winning other roles (big bonus (2 ) + Loss or Regular Bonus (1) + Loss), the average number of frames drawn when the “watermelon” symbol stops at the lower or middle of the left reel is 7.83. In other words, when the “watermelon” symbol that constitutes the chance eye in the left reel is derived, any bonus is won in the normal gaming state than in the case where no role is won in the normal gaming state. If the winning combination has not been won, the average number of draws will be higher, and the “watermelon” symbol that constitutes the chance will be derived on the left reel. The amount of fluctuation until it stops is increased.

  In addition, when none of the winning combinations is won in the normal gaming state (losing), the left reel is stopped at the timings of the area numbers 17, 19, 21, and 23, which are the derivation conditions for the chances. Or if the “Watermelon” symbol stops in the middle row, the “Watermelon” symbol stops in the middle row of the middle reel, and the average number of draws when the chance item is tempered on the winning line is 1.14. When the operation of stopping the middle reel is performed at a timing satisfying the derivation condition of the eyes, the average number of frames to be drawn when the “watermelon” symbol stops at the middle stage of the middle reel is 3. In addition, when the big bonus (1) is won in the normal gaming state and other roles are not won (Big Bonus (1) + Loss), the “Watermelon” symbol stops at the bottom of the left reel. If the “watermelon” symbol stops in the middle row of the middle reel, the average number of draws when the chance is tempered on the winning line is 3.5, and the “watermelon” symbol stops in the middle row of the left reel In addition, the “watermelon” symbol stops in the middle of the middle reel, and the average number of draws when the chance item is tempered on the winning line is 3.17. In the normal gaming state, the big bonus (2) or regular bonus (1 ) And not in any other role (Big Bonus (2) + Loss or Regular Bonus (1) + Loss) If other you stop the "watermelon" symbol in the middle, in the middle of the middle reel stops "watermelon" symbol, the average number of lead-frame of when the opportunity first to Tenpai on the pay line will be 3.55. In other words, when the “watermelon” symbol constituting the chance eye is derived on the middle reel and the chance eye is tempered on the winning line, the normal gaming state is more than the case where no role is won in the normal gaming state. If you have won one of the bonuses and have not won any other role, the average number of draws will be larger and the stop operation will be performed when the chance is tempered on the winning line. The amount of change from when it is broken until the reel stops is large.

  Next, commands that the CPU 41a of the main control unit 41 transmits to the effect control board 90 will be described.

  In this embodiment, the CPU 41a of the main control unit 41 sends a plurality of types of commands to the effect control board 90 including an internal winning command, a reel rotation start command, a reel stop command, a winning determination command, a gaming state command, and a standby command. Send.

  The internal winning command is a command that can specify the winning status of the internal winning flag and the type of the internal winning flag that has been established, and is transmitted when the start switch 7 is operated to start the game.

  The reel rotation start command is a command for notifying the start of reel rotation, and is transmitted when rotation of the reels 2L, 2C, and 2R is started.

  The reel stop command is a command that can specify whether the reel to be stopped is the left reel, the middle reel, or the right reel, the area number of the corresponding reel stop operation position, and the area number of the corresponding reel stop position. And is transmitted each time stop control of each reel is performed.

  The winning determination command is a command that can specify the presence / absence of winning, the type of winning, and the number of medals to be paid out at the time of winning, and is transmitted after all the reels are stopped and the winning determination is performed.

  The gaming state command is a command that can specify the gaming state of the next game (whether it is a normal gaming state, a big bonus, a regular bonus, etc.), and is transmitted at the end of the game.

  The standby command is a command indicating a transition to the standby state, and is transmitted when the transition to the standby state is made after a certain time has elapsed without setting the bet amount after the end of one game.

  These commands are generated in a startup process and a game process described later, temporarily stored in a command queue provided in the RAM 41c, and transmitted in the timer interrupt process described above.

  Next, the control of the effect performed by the sub control unit 91 based on the command transmitted from the CPU 41a of the main control unit 41 to the effect control board 90 will be described.

  When the CPU 91a of the sub control unit 91 receives a command transmitted by the CPU 41a of the main control unit 41, the CPU 91a refers to the control pattern table stored in the ROM 91b, and displays the liquid crystal display based on the control content registered in the control pattern table. The various effect devices such as the device 51, the effect LED 52, the speakers 53 and 54, and the reel LED 55 are controlled.

  In the control pattern table, the display pattern of the liquid crystal display 51 corresponding to the type of command, the lighting mode of the lighting effect LED 52, the output mode of the speakers 53 and 54, the lighting mode of the reel LED, etc. The control patterns of these effect devices are registered, and when the CPU 91a receives a command, the CPU 91a receives among the control patterns registered corresponding to the effect patterns set in the RAM 91c in the game of the control pattern table. The control device corresponding to the type of the command is referred to, and the rendering device is controlled based on the control pattern. Thereby, the production according to the production pattern and the progress of the game is executed.

  Further, the CPU 91a of the sub-control unit 91 continuously executes over a plurality of games, and executes a continuous effect for notifying whether or not a bonus has been won.

  FIG. 14A is a flowchart showing the flow of the continuous effect, and FIG. 14B is a diagram showing the winning probability in the continuous effect lottery.

  As shown in FIG. 14A, the CPU 91a executes a continuous effect lottery that determines whether or not to execute a continuous effect every time an internal winning command is received in the normal gaming state, that is, every time an internal lottery is performed. To do. Then, when the continuous effect lottery is won, the continuous effect is executed. On the other hand, even when the continuous effect lottery is not won, if the chance stops, the continuous effect is executed. In addition, when the chance eyes are stopped during the execution of the continuous performance, the chance sales are invalidated, and the continuous performance is not newly executed. Further, after winning one of the bonuses, the continuous effect is executed even once, and if the bonus is announced, the continuous effect lottery is not performed thereafter. That is, after winning one of the bonuses, the continuous effect is executed even once, and when the bonus is announced, the continuous effect is not further executed.

  Further, a chance eye counter indicating the chance eye appearance rate is set in the RAM 91c of the sub-control unit 91, and the CPU 91a performs a process of updating the game chance eye counter according to the presence or absence of the chance eye. .

  The CPU 91a initializes (updates to 0) the value of the chance eye counter when the sub control unit 91 is activated. Then, when the display result is derived for all the reels in each game in the normal gaming state, it is determined whether or not the chance eye is derived. If the chance eye is not derived, the value of the chance eye counter is set to 1. If the chance eye is derived, the value of the chance eye counter is incremented by 300. Thereby, when the appearance rate of the chance eye from the time of starting the sub-control unit 91 exceeds 1/300, the value of the chance eye counter exceeds 0, and when it is 1/300 or less, the chance chance counter The value of the eye counter is 0 or less. That is, the value of the chance eye counter can specify whether the appearance rate of chance eyes from the time of activation exceeds 1/300 or 1/300 or less.

  In the continuous effect lottery, as shown in FIG. 14B, the winning probability varies depending on whether or not any bonus is won in the normal gaming state, and furthermore, when any bonus is not won. Is a probability of winning depending on whether the appearance rate of the chance eye in the normal gaming state exceeds 1/300 or 1/300 or less, that is, whether the value of the above-mentioned chance eye counter exceeds 0 or 0 or less. Is different.

  Specifically, in the case where no bonus is won in the normal gaming state, and the chance rate of appearance in the normal gaming state exceeds 1/300, the winning probability of 3/1993 (1 / 664.33) In the case where the execution of the continuous production is determined and no bonus is won in the normal game state, and the chance rate of appearance in the normal game state is 1/300 or less, 10/1993 (1 / If the execution of the continuous performance is decided with the winning probability of 199.3) and any bonus is won in the normal gaming state, the continuous performance is performed with the winning probability of 350/1993 (1 / 5.69). Decide on execution.

  As described above, in this embodiment, the continuous performance is executed when the chance is derived in the normal gaming state. In addition, the continuous effect lottery is executed in each game in the normal gaming state, and the continuous effect is also executed when winning the continuous effect lottery. That is, even when the chance is not derived, if the continuous production lottery is won, the continuous production is executed.

  In addition, when none of the bonuses is won in the normal gaming state, when the chance rate of appearance is a predetermined rate (1/300) or less, the chance rate of appearance is a predetermined rate (1 / The execution of the continuous performance is determined with a higher probability than in the case of exceeding 300).

  Further, in this embodiment, the winning probability (1 / 664.33) of the continuous performance when the appearance rate of chance chances exceeds 1/300 in the normal gaming state is won for any role in the normal gaming state. If there is no chance (losing), it is lower than the probability that the chance is derived (1 / 514.5), and if a bonus is won in a normal gaming state, the winning probability of continuous production (1 / 5.69) ) Is a chance that a chance is derived when one of the bonuses is won in the normal gaming state and the other combination is not won (1 when the big bonus (1) is won) /21.29, higher than 1 / 1.37 when the big bonus (2) or regular bonus (1) is won, so the chance rate of appearance in the normal gaming state is 1/30 In situations where the number of bonuses is over, the bonus will be won when the continuous production is executed without the appearance of the chance, rather than when the continuous production with the appearance of the chance is executed. There is a high possibility of being.

  The CPU 91a of the sub-control unit 91 performs control to output a reel stop sound every time a reel stop command is received, that is, every time the reel stops.

  The reel stop sound includes a stop sound A and a stop sound B, and the CPU 91a performs a control to always output the stop sound A in a game state (small role game, regular bonus) other than the normal game state.

  In the normal gaming state, control is performed to output one of the stop sounds A and B. Specifically, if no winning combination is won in the normal gaming state, a stop operation of the left reel is detected at the timing of area numbers 17, 19, 21, and 23 while all reels are rotating. When a reel stop command indicating that the number “watermelon” symbol has stopped in the lower or middle stage is received, that is, when the stop operation position of the left reel satisfies the chance derivation condition, a stop sound is generated at a ratio of 20/31. Control for outputting A is performed, and control for outputting stop sound B at a ratio of 11/31 is performed. On the other hand, when a stop operation of the left reel is detected at the timing of the area numbers 16, 18, 20, 22 and a reel stop command is received indicating that the number 8 “watermelon” symbol has stopped at the lower or middle level, that is, left When the reel stop operation position does not satisfy the chance eye derivation condition, but the display result is such that the chance eye can be derived, control is performed to output the stop sound A at a ratio of 29/31. Control is performed to output stop sound B at a rate.

  In the state where only the left reel has been stopped and the stop operation of the left reel has been detected at the timing of the area numbers 17, 19, 21, 23, and the “Watermelon” symbol of No. 8 has stopped in the lower or middle stage, the area number When a middle reel stop operation is detected at timings 23 and 41, and a reel stop command is received indicating that the 9th or 18th “watermelon” symbol has stopped in the middle stage, that is, the left reel and middle reel stop operation When the position satisfies the derivation condition for the chance, control is performed to output the stop sound A at a ratio of 15/31, and control is performed to output the stop sound B at a ratio of 16/31. On the other hand, in a state where only the left reel has been stopped and the stop operation of the left reel is detected at the timing of the area numbers 17, 19, 21, and 23, and the “watermelon” symbol of No. 8 is stopped at the lower stage or the middle stage, When a stop operation of the middle reel is detected at a timing other than the area numbers 23 and 41 and a reel stop command is received indicating that one of the “watermelon” symbols has stopped in the middle stage, or only the left reel has been stopped. In addition, when the stop operation of the left reel is detected at the timing of the area numbers 16, 18, 20, and 22, and the “watermelon” symbol of No. 8 is stopped at the lower stage or the middle stage, the stop operation of the middle reel is detected. When the “watermelon” symbol is received in a reel stop command indicating that it has stopped in the middle, that is, the stop operation position of the left reel or the middle reel is the chance Control that outputs stop sound A at a ratio of 30/31 and outputs stop sound B at a ratio of 1/31 when a display result that does not satisfy the output condition but a chance chance can be derived. I do.

  In a situation where the left reel and the middle reel have been stopped, and the stop operation position of the left reel and the middle reel satisfies the chance eye derivation condition, the right reel stop operation is detected and the chance eye is established. When a reel stop command indicating that the “watermelon”, “7”, and “BAR” symbols have stopped is received, that is, when a chance is derived when all reels stop, a ratio of 10/31 The control for outputting the stop sound A is performed at, and the control for outputting the stop sound B at a ratio of 21/31 is performed.

  Further, if any bonus is won in the normal gaming state and no other combination is won, a stop operation of the left reel is detected while all reels are rotating, and the number “8” When a reel stop command indicating that the “watermelon” symbol has stopped at the lower or middle stage is received, that is, when the left reel stop position satisfies the chance derivation condition, the stop sound A is output at a ratio of 15/31. Control is performed to output stop sound B at a ratio of 16/31.

  When only the left reel has been stopped and the number 8 “watermelon” symbol is stopped at the lower or middle level, a stop operation of the middle reel is detected and one of the “watermelon” symbols has stopped at the middle level. When the reel stop command shown is received, that is, when the stop positions of the left reel and the middle reel satisfy the chance derivation condition, control is performed to output the stop sound A at a ratio of 10/31, and a ratio of 21/31. The control for outputting the stop sound B is performed.

  In a situation where the left reel and the middle reel have been stopped, and the stop operation position of the left reel and the middle reel satisfies the chance eye derivation condition, the right reel stop operation is detected and the chance eye is established. When a reel stop command indicating that the “watermelon”, “7”, and “BAR” symbols have stopped is received, that is, when chances are derived when all reels stop, a ratio of 5/31 The control for outputting the stop sound A is performed at, and the control for outputting the stop sound B at a ratio of 26/31 is performed.

  As described above, in this embodiment, every time the reels stop, whether the reel to be stopped is any one of the left reel, the middle reel, and the right reel, the area number of the stop operation position of the corresponding reel, and the stop of the corresponding reel. Since a reel stop command capable of specifying the position area number is transmitted to the sub-control unit 91, the CPU 91a of the sub-control unit 91 stops the reel when the reel stops. Different effects can be performed depending on not only the position but also the stop operation position.

  In particular, in this embodiment, when no combination is won in the normal gaming state, when the left reel and the middle reel are stopped, the stop position of the left reel and the middle reel is finally derived as a chance. Even if it is the same as the stop position, if the stop operation position of the left reel and the stop operation position of the middle reel do not satisfy the chance eye derivation condition, the chance eye is not finally derived. When the reel stop command is received and the stop operation position satisfies the chance derivation condition, the stop operation position does not satisfy the chance derivation condition, but the display result is such that the chance eye can be derived. Control for outputting the stop sound B at a higher rate is performed. For this reason, when the left reel and the middle reel are stopped, even if the same display result is obtained, there is a possibility that the chance chance is finally derived when the stop sound B is output rather than the stop sound A is output. Rise.

  Also, in this embodiment, when each reel is stopped, the stop sound is played at a higher rate when one of the bonuses is won in the normal gaming state than when no combination is won. Since B is output, it is more likely that one of the bonuses is won when the stop sound is output than when the stop sound A is output when each reel is stopped. The more reels that are output, the higher the chance that one of the bonuses has been won.

  Next, various control contents executed by the CPU 41a of the main control unit 41 in the present embodiment will be described below with reference to FIGS.

  When the reset signal is input from the reset circuit 49, the CPU 41a performs a startup process shown in the flowchart of FIG. Since the reset signal is a signal output when the power is turned on and when the operation of the main control unit 41 is stagnant, the activation process is performed when the CPU 41a is activated when the power is turned on and when the CPU 41a is activated due to a malfunction. This is a process to be performed.

  In the start-up process, first, the built-in device, peripheral IC, interrupt mode, stack pointer, etc. are initialized (Sa1), then the voltage drop signal detection data is acquired from the input port, and whether or not the voltage drop signal is input. That is, it is determined whether or not the voltage is stable (Sa2), and if the voltage drop signal is input, any processing is performed except for determining whether or not the voltage drop signal is input. There is no loop processing.

  If it is determined in step Sa2 that the voltage drop signal is not input, the values of the I register and IY register are initialized (Sa3), the state of the stop switch 36 is acquired, and a specific register of the CPU 41a is acquired. The valid / invalid of the stop function is set in (Sa4). By the initialization of the I register and the IY register, the address of the interrupt table to be referred to when an interrupt occurs is set in the I register, and the reference address for referring to the storage area of the RAM 41c is set in the IY register. . These values are fixed values and are always initialized at startup.

  Next, access to the RAM 41c is permitted (Sa5), and it is determined whether or not the setting key switch 37 is in an ON state (Sa6). If the setting key switch 37 is not in the ON state in step Sa6, the RAM parity of all storage areas (including the unused area and the unused stack area) of the RAM 41c is calculated (Sa7). Is determined (Sa8). If the power interruption interrupt processing is normally performed, the RAM parity should be 0. If the RAM parity is not 0 in the step of Sa8, the data stored in the RAM 41c is not normal. An error code indicating abnormality is set in the register (Sa10), and the process proceeds to error processing shown in FIG.

  If the RAM parity is 0 in step Sa8, it is further determined whether or not the destructive diagnosis data is normal (Sa9). If power interruption interrupt processing is performed normally, the data for destruction diagnosis should be set. If the data for destruction diagnosis is not normal in step Sa9 (the data for destruction diagnosis is stored at the time of power interruption. In the case other than 5A (H), the data in the RAM 41c is not normal, so an error code indicating a RAM abnormality is set in the register (Sa10), and the process proceeds to the error processing shown in FIG.

  In the error processing, as shown in FIG. 16, the current display state of the game auxiliary display 12 is saved in the stack (Sb1), and the error code set in the RAM 41c is displayed on the game auxiliary display 12 (Sb2). .

  Next, the error code set in the register is confirmed, it is determined whether the error code is an error code indicating a RAM abnormal error (Sb3), and an error code indicating an error code indicating a RAM abnormal error is set. If it is determined that the error code is an error code indicating a RAM abnormality error, the process proceeds to a loop process in which no process is performed except for the determination.

  If an error code indicating a non-RAM error is set in step Sb3, it is determined whether an operation of the reset / setting switch 38 is detected (Sb4). If the operation is not detected, it is further determined whether or not the operation of the reset switch 23 is detected (Sb5). If the operation of the reset switch 23 is not detected, the process returns to the step Sb4. That is, the game waits in a state where the progress of the game is impossible until the operation of the reset / setting switch 38 or the reset switch 23 is detected.

  When the operation of the reset / setting switch 38 is detected in the step Sb4 or when the operation of the reset switch 23 is detected in the step Sb5, the error code set in the register is cleared (Sb6 ), The display state of the game auxiliary display 12 is returned to the display state saved in the stack in step Sb1 (Sb7), and the process returns to the original process.

  As described above, in the error processing, if the error processing is other than the RAM abnormality error, the reset / setting switch 38 or the reset switch 23 is operated to return to the original processing even if the error state is canceled. In the case of error processing due to a RAM abnormality error, the error state is not canceled even if the reset / setting switch 38 or the reset switch 23 is operated.

  Returning to FIG. 15, if it is determined in step Sa9 that the data for destructive diagnosis is normal, the data in the RAM 41c is normal, so the non-saved work, the unused area, and the unused stack area in the RAM 41c are initialized. After performing initialization 3 (Sa11), the destruction diagnosis data is cleared (Sa12). Next, each register is restored to the state before the power interruption, that is, the state saved in the stack (Sa13), the interrupt is permitted (Sa14), and the process that was executed last before the power interruption is returned.

  If the setting key switch 37 is in the ON state in the step of Sa6, after executing initialization 1 for initializing all storage areas in the storage area of the RAM 41c except the used stack area (Sa15), The value (0 at this time) stored in the set value work is corrected to 1 (Sa16). Next, interruption is permitted (Sa17), and the setting change process shown in FIG. 17, ie, the setting change mode is entered (Sa18). After the setting change process is completed, the process proceeds to the game process.

  In the setting change process, as shown in FIG. 17, the setting value stored in the setting value work of the RAM 41c (the value of the setting value work is corrected to 1 before shifting to the setting changing process. Is read out (Sc1).

  Thereafter, the operation waits for detection of the operation of the reset / setting switch 38 and the start switch 7 (Sc2, Sc3). When the operation of the reset / setting switch 38 is detected in the step of Sc2, the setting value read in the step of Sc1. 1 is added (Sc4), and it is determined whether or not the set value after addition is 7, that is, whether or not the settable range is exceeded (Sc5). If the set value after addition is not 7, After returning to the detection waiting state for the operation of the reset / setting switch 38 and the start switch 7 in the steps Sc2 and Sc3 again, if the setting value after addition is 7 in the step Sc5, the setting value is corrected to 1 (Sc6). ), The process returns to the detection waiting state for the operation of the reset / setting switch 38 and the start switch 7 in the steps Sc2 and Sc3.

  When the operation of the start switch 7 is detected in the step of Sc3, the changed set value selected at that time is stored in the set value work of the RAM 41c and the set value is confirmed (Sc7). Wait until the setting key switch 37 is turned off (Sc8). If it is determined in step Sc8 that the setting key switch 37 is OFF, the process returns to the flowchart of FIG.

  As described above, in the startup process, when the setting key switch 37 is not in the ON state, it is stored in the RAM 41c by determining whether or not the RAM parity is 0 and whether or not the destructive diagnosis data is normal. It is determined whether or not the stored data is normal. If the data in the RAM 41c is not normal, the process proceeds to an abnormal error process. In the error processing due to the RAM abnormal error, an error code indicating the RAM abnormal error is displayed on the game auxiliary display 12, and then the process proceeds to a loop process in which no processing is performed, so that the progress of the game is disabled. If the data in the RAM 41c is not normal, interrupts are not permitted. Therefore, once the process shifts to error processing due to a RAM error, the setting key switch 37 is activated and interrupts are permitted. Until it is interrupted, no power interruption processing is performed even if the power is interrupted. That is, the RAM adjustment data is not calculated and stored so that the RAM parity is newly set to 0 in the power interruption interrupt process, and the destruction diagnosis data is not newly set. Even if the game is started, the game cannot be resumed even if the CPU 41a is restarted except when the setting key switch 37 is turned on.

  Once the process shifts to error processing due to a RAM abnormality error, the setting key switch 37 is activated in the ON state, and after all the areas except the used stack area of the RAM 41c are initialized, a setting change process is performed. The game cannot be progressed until a new set value is selected and set by operating the reset / setting switch 38. In other words, in the state where the error processing due to the RAM abnormality error is started, the state in which the game cannot be progressed is canceled and the game is resumed on the condition that a new set value is selected and set by operating the reset / setting switch 38. It becomes possible to make it.

  FIG. 18 is a flowchart showing the control contents of the game process executed by the CPU 41a.

  In the game process, a BET process (Sd1), an internal lottery process (Sd2), a reel rotation process (Sd3), a winning determination process (Sd4), a payout process (Sd5), and a game end process (Sd6) are sequentially executed. When the end-time process ends, the process returns to the BET process again.

  In the BET process in the step of Sd1, the process waits in a state where the bet number can be set, sets a predetermined number of bets according to the gaming state, and executes a process of determining the bet number when the start switch 7 is operated. To do.

  In the internal lottery process in step Sd2, a random number for internal lottery is extracted simultaneously with the start of the game by the detection of the start switch 7 in step Sd1, and the winning of each above-described combination is permitted based on the extracted random number value. Process to determine whether or not. In this internal lottery process, a winning flag is set in the RAM 41c based on the respective lottery results.

  In the reel rotation process in the step of Sd3, the process of rotating each reel 2L, 2C, 2R and the operation of the corresponding reel 2L, 2C, 2R in response to the operation of the stop switch 8L, 8C, 8R detected by the player are detected. A process for stopping the rotation is executed.

  In the winning determination process in the step Sd4, when it is determined in the step Sd3 that the rotation of all the reels 2L, 2C, and 2R is stopped, the winning is determined according to the display result derived for each reel 2L, 2C, and 2R. A process of determining whether or not it has occurred is executed.

  In the payout process in step Sd5, when it is determined that a prize is generated in step Sd4, processing such as addition of credits and payout of medals is performed based on the number of payouts according to the win.

  In the game end process in the step of Sd6, a process of setting a gaming state in preparation for the next game is executed.

  FIGS. 19-21 is a flowchart which shows the control content of the internal lottery process which CPU41a performs in the step of Sd2.

  In the internal lottery process, first, a random number acquisition process whose details will be described later is performed (Sg1). In this random number acquisition process, a random number value for internal lottery is acquired based on a random number generated by a random number generation circuit (not shown).

  Then, the set value stored in the set value work of the RAM 41c is read (Sg2), and whether or not the read set value is in the range of 1 to 6, that is, the set value stored in the set value work is an appropriate value. If the read set value is not in the range of 1 to 6, an error code indicating RAM abnormality is set in the register (Sg4), and the process proceeds to the error process shown in FIG.

  Further, if the set value read in the step of Sg4 is in the range of 1 to 6, it is determined whether or not the current gaming state is the normal gaming state (Sg5), and if it is the normal gaming state, the normal gaming state Correspondingly, the small combination and re-game combination are read out in the order registered in the winning combination table according to gaming state shown in FIG. 4A (Sg6). The BET number (the number of bets) set in the step of Sd1 is read, and the common flag of the combination corresponding to the combination and the combination of the replaying combination shown in FIG. The setting status is acquired (Sg7). As a result, it is determined whether or not a common flag is set for the combination and the BET number (Sg8).

  If the common flag is set, the number of determination values stored at the address registered in the role-specific table for the small combination and re-playing combination in FIG. (Sg9). Then, the process proceeds to Sg11. If the common flag is not set, the number of judgment values stored at the address registered in the role-specific table for the small combination and re-playing combination corresponding to the set value read for the combination and the BET number Obtain (Sg10). Then, the process proceeds to Sg11.

  In the step of Sg11, the number of determination values acquired in the step of Sg9 or Sg10 is added to the random number value for internal lottery, and the result of the addition is used as a new random number value for internal lottery. Here, it is determined whether or not an overflow has occurred when the number of determination values is added to the random number for internal lottery (Sg12). If an overflow occurs, the winning flag for the combination is set in the RAM 41c (Sg13). Then, the process proceeds to Sg15 shown in FIG.

  If no overflow has occurred in the step of Sg12, it is determined whether or not there is a combination that has not yet been set as a processing target among the small combination and re-playing combination defined for the normal gaming state (Sg14). If there is a combination that has not yet been processed, the process returns to the processing of Sg6, and the processing continues with the next combination from the small combination and re-playing combination defined for the normal gaming state as the processing target. If there is no combination not to be processed, the process proceeds to Sg15 shown in FIG.

  In step Sg15, it is determined whether a regular bonus or a big bonus winning flag has already been set in the RAM 41c in the previous game or not, and the game is carried over without winning based on the winning flag. If the winning flag for the regular bonus or the big bonus has already been set, the internal lottery process is terminated and the process returns to the flowchart of FIG. If neither the regular bonus winning flag nor the big bonus winning flag is set, the random number for internal lottery is returned to the value before addition, that is, the value acquired in the random number acquisition process of Sg1 (Sg16).

  Next, with reference to the winning combination table according to gaming state shown in FIG. 4A and the special role combination table shown in FIG. 4C, lottery of the normal gaming state registered in the winning combination table according to gaming state The target special combination is read out in the order registered in the special combination table for special combination (Sg17). At this time, if the special role lose is registered in the special role-specific table, the special role loses are also read in the registered order. Furthermore, the setting state of the common flag is acquired from the role-specific table for special roles in FIG. 4C (Sg18). As a result, it is determined whether or not a common flag is set for the combination (Sg19).

  If the common flag is set, the number of judgment values stored in the address registered in the special role-specific table of FIG. 4C for the role is acquired (Sg20). Then, the process proceeds to Sg22. If the common flag is not set, the number of determination values stored in the address registered in the special role-specific table corresponding to the set value read for the corresponding role is acquired (Sg21). Then, the process proceeds to Sg22.

  In the step of Sg22, the number of determination values acquired in the step of Sg20 or Sg21 is added to the random number value for internal lottery, and the result of the addition is used as a new random number value for internal lottery. Here, it is determined whether or not an overflow has occurred when the number of determination values is added to the random number for internal lottery (Sg23). When an overflow occurs, it is determined whether or not the combination is lost (Sg24). If the winning combination is lost, the internal lottery process is terminated and the process returns to the flowchart of FIG. If the winning combination is not lost, the winning flag for the winning combination is set in the RAM 41c (Sg25). Then, the internal lottery process is terminated, and the process returns to the flowchart of FIG.

  If no overflow has occurred in the step of Sg23, it is determined whether or not there is a combination that has not yet been processed (Sg26). If there is a combination that has not yet been processed, the process returns to the processing of Sg17, and the processing is continued with the next combination from the special combination (including the special combination lost) determined for the normal gaming state as the processing target. If there is no combination not to be processed, the internal lottery process is terminated and the process returns to the flowchart of FIG.

  In the step of Sg5, if the current gaming state is not the normal gaming state, it is determined whether or not it is a small role game (Sg27). If it is a small role game, corresponding to the small role game, the combinations registered in the winning combination table by gaming state in FIG. 4A are sequentially read (Sg28), and the process proceeds to Sg30. If it is not a small role game in the step of Sg27, it is a regular bonus. Therefore, in correspondence with the regular bonus, the roles registered in the winning combination table according to the gaming state in FIG. Proceed to the process.

  In step Sg30, it is determined whether or not the type of the combination read in steps Sg28 and Sg29 is regular bonus (2) or JACIN. In the case of regular bonus (2) or JACIN, whether the winning flag of regular bonus (2) has already been set in the RAM 41c in the previous game or not, and it is determined whether it has been carried over without winning based on the winning flag (Sg31). If the type of the read combination is neither regular bonus (2) nor JACIN, the process proceeds to Sg32.

  If the winning flag for the regular bonus (2) has already been set, the internal lottery process is terminated, and the process returns to the flowchart of FIG. 18 (Regular bonus (2) and JACIN are selected by gaming state as described above) Since it is registered after the small role in the table, the internal lottery process is completed.) Even if the type of the read combination is regular bonus (2) or JACIN, if the winning flag for regular bonus (2) is not set, the process proceeds to Sg32.

  In step Sg32, the number of BETs (number of bets) set in step Sd1 is further read, and the combination corresponding to the combination and the read number of BETs is obtained from the corresponding role-specific table in FIGS. 4B and 4C. Get the setting status of the common flag. As a result, it is determined whether or not a common flag is set for the combination and the BET number (Sg33).

  If the common flag is set, the number of judgment values stored in the address registered in the corresponding role-specific table in FIGS. 4B and 4C is acquired for the role and the BET number (Sg34). . Then, the process proceeds to Sg36. If the common flag is not set, the determination stored in the address registered in the corresponding role table shown in FIGS. 4B and 4C corresponding to the set value read for the role and the BET number. The number of values is acquired (Sg35). Then, the process proceeds to Sg36.

  In the step of Sg36, the number of determination values acquired in the step of Sg34 or Sg35 is added to the random number value for internal lottery, and the result of addition is used as a new random number value for internal lottery. Here, it is determined whether or not an overflow has occurred when the number of determination values is added to the random number value for internal lottery (Sg37). If an overflow occurs, the winning flag for the combination is set in the RAM 41c (Sg38). Then, the internal lottery process is terminated, and the process returns to the flowchart of FIG.

  If no overflow has occurred in the step of Sg37, it is determined whether or not there is a combination that has not yet been processed among the combinations determined for the gaming state (Sg39). If there is a combination that has not yet been processed, the process returns to Sg27, and the process continues with the next combination defined for the gaming state as the processing target. If there is no combination not to be processed, the internal lottery process is terminated and the process returns to the flowchart of FIG.

  As described above, in the internal lottery process, it is confirmed whether or not the set value stored in the set value work of the RAM 41c is an appropriate value. An error code indicating an error is set, and the process proceeds to error processing. As in the case where it is determined that the data in the RAM 41c is not normal at the time of startup, an error state due to a RAM abnormality error occurs and the progress of the game is disabled. It has become.

  Also, in the normal gaming state, since the random number for the same internal lottery is drawn separately for the small role and the re-playing role and the special role, the random number to be won in the normal gaming state A small combination (cherry in the present embodiment) and a special combination (big bonus (1) (2) in the present embodiment) with overlapping ranges may be won simultaneously.

  Next, the random number acquisition process in step Sg1 will be described in detail based on the flowchart of FIG. In the random number acquisition process, first, interrupts are prohibited (Sh1). Next, a sampling command is output to the sampling circuit 43, the random number generated by the random number generation circuit 42 is latched, and the value of the latched random number is input from the I / O port 41d and extracted. The random number value extracted from the random number generation circuit 42 is stored in the general-purpose register 41GR (Sh2).

  Next, the lower byte value and upper byte value of the random number stored in the general-purpose register 41GR are exchanged with each other using the work area of the RAM 41c (Sh3). At this time, the value stored in the general-purpose register 41GR is acquired as a random number for internal lottery and stored in a predetermined area of the RAM 41c (Sh4). Then, after permitting the interrupt prohibited in the step of Sh1 (Sh5), the random number acquisition process is terminated and the process returns to the flowchart of FIG.

  FIG. 23 is a flowchart showing the control contents of the reel rotation process executed by the CPU 41a in step Sd3.

  In the reel rotation process, first, it is determined whether or not a wait time (about 4.1 seconds in this embodiment) has elapsed since the reel rotation start time of the previous game (Si1), and the wait time must have elapsed. For example, it waits until the wait time elapses.

  If the wait time has elapsed in the Si1 step, a new wait time is set (Si2).

  Next, the work initialization code at the start of the rotation of the reel motor is set in the register, and the rotation of the reel is started (Si3). Then, referring to the table index, the table creation data is specified, and the stop control table corresponding to the game state of the game, the winning combination status of the game, and the stop status of other reels based on the specified table creation data Is created for each rotating reel (Si4), and the work initialization code at the time of completion of stop preparation is set in the register (Si5). As a result, the stop operation can be validated, and then the stop operation becomes valid when a constant-speed rotation of the reel is detected in the process at the time of passing through the origin of the timer interrupt process described later.

  Next, it is determined whether or not an operation of any one of the stop switches 8L, 8C and 8R is detected (Si6). If no operation of any stop switch is detected, a reel rotation error (over a certain period of time). Then, it is determined whether or not an error determined when the reel reference position is not detected by the reel sensor 33 (Si7). If no reel rotation error has occurred, an insertion error (medal insertion) is further performed. Whether or not a medal insertion was detected outside the permitted period, and whether or not a payout error (medal payout was detected outside the medal payout period) It is determined whether or not an error has occurred (Si8, Si9), and any error occurs in steps Si7 to Si9. If it is not determined, the flow returns to step Si6.

  Further, when it is determined that a loading error has occurred in the Si8 step, or when a dispensing error is determined in the Si9 step, an error code indicating a loading / dispensing error during reel rotation is set in the register (Si10 ), The process proceeds to the error process shown in FIG. 12 (Si11). When the error is released, the process returns to the Si6 step again.

  If it is determined in step Si7 that a reel rotation error has occurred, an error code indicating a reel rotation error is set in the register (Si12), and the process proceeds to error processing shown in FIG. 12 (Si13). Along with this, the rotation of the reels is also temporarily stopped. When the error is released, the process returns to the Si3 step again and the reel rotation is resumed.

  If any stop switch operation is detected in the Si6 step, the number of steps from the reel reference position at that time (the number of steps to be the stop operation position) in the reel motor corresponding to the stop switch is calculated. After obtaining and setting the workpiece corresponding to the stop reel (Si14), the process waits until the rotation of the reel corresponding to the stop operation stops (Si15).

  When the rotation of the reels corresponding to the stop operation stops, it is determined whether or not all the reels have stopped (Si16). If all the reels have not stopped, the process returns to the Si4 step, and all the reels are If stopped, the reel rotation process is terminated and the process returns to the flowchart of FIG.

  As described above, in the reel rotation processing, after the rotation of the reels 2L, 2C, and 2R is started, the rotation of the reels for which the stop operation has not been detected is continued until the operation of the stop switches 8L, 8C, and 8R is detected. Then, on the condition that the operation of the stop switches 8L, 8C, and 8R is detected, control is performed to stop the display result on the corresponding reel. Even if the reel rotation temporarily stops due to the occurrence of a reel rotation error, the stop operation is still detected until the operation of the stop switches 8L, 8C, and 8R is detected after the reel rotation is restarted. Control is performed to stop the display result of the corresponding reels on the condition that the rotation of the reels that have not been continued is continued and the operation of the stop switches 8L, 8C, and 8R is detected.

  24 and 25 are flowcharts showing the control contents of the timer interrupt process executed by the CPU 41a by interrupting the start process or the game process in response to the occurrence of the interrupt 3, that is, at an interval of 0.56 ms.

  In the timer interrupt process, interrupts are first prohibited (Sj1). That is, the execution of another interrupt process during the execution of the timer interrupt process is prohibited. Then, the register in use is saved in the stack area (Sj2).

  Next, the branch counter for identifying the timer interrupt to be executed in the timer interrupt process is advanced by 1 from the four types of timer interrupts 1 to 4 (Sj3). In step Sj3, 1 is added when the branch counter value is 0 to 2, and is updated to 0 when the counter value is 3. That is, the branch counter value loops in the order of 0 → 1 → 2 → 3 → 0... Each time the timer interrupt process is executed.

  Next, the branch counter value is referred to determine whether it is 2 or 3, that is, timer interrupt 3 or timer interrupt 4 (Sj4). If it is not timer interrupt 3 or timer interrupt 4, that is, timer interrupt In the case of 1 or timer interrupt 2, it is checked whether the reel motors 32L, 32C, 32R are started or whether they are rotating at a constant speed, and whether the reel motors 32L, 32C, 32R are started or are rotating at a constant speed. For example, the motor phase signal output process for outputting the phase signal data changed in the motor step process of Sj8 described later and the phase signal data changed in the final stop process of Sj23 described later is executed (Sj5).

  Next, it is determined whether or not it is 1 (ie, timer interrupt 2) by referring to the minute counter value (Sj6). If it is not timer interrupt 2 (ie, timer interrupt 1), the reel motor Reel start processing (Sj7) for controlling the step time interval when starting 32L, 32C, 32R, motor step processing (Sj8) for changing phase signal data of the reel motors 32L, 32C, 32R, reel motors 32L, 32C After the stop of 32R, the motor phase signal standby process (Sj9) for changing the phase signal to one-phase excitation after a certain time has been sequentially executed, and then the register saved in the stack area in Sj2 is restored (Sj20). The interrupt prohibited in the step is permitted (Sj21), and the process returns to the process before the interrupt.

  In the case of timer interrupt 2 in step Sj6, LED dynamic display processing (Sj10) for dynamically lighting various indicators, and output processing for control signals and the like for outputting data such as lighting signals for various LEDs to the output port (Sj11), random number update processing for updating various software random numbers (Sj12), time counter update processing for updating various time counters (Sj13), command transmission for transmitting commands stored in the command queue to the effect control board 90 After the processing (Sj14) and the external output signal update processing (Sj15) for updating the external output signal are sequentially executed, the register saved in the stack area in Sj2 is restored (Sj20), and the interrupts prohibited in the step of Sj1 are permitted. (Sj21), and the process returns to the state before the interruption.

  If it is timer interrupt 3 or timer interrupt 4 in step Sj4, it is further determined whether or not it is 3, that is, timer interrupt 4 by referring to the counter value for occurrence (Sj16). If it is not interrupt 4, that is, timer interrupt 3, port input processing (Sj17) for inputting detection data of various switches from the input port, passing the origin of the reels 2L, 2C, 2R during rotation (reel reference) Pass position), detect the occurrence of a reel rotation error, check whether the initialization code at the time of stop preparation completion is set, the initialization code at the time of stop preparation completion is set, and If it is rotating at a constant speed, the process at the time of passing through the origin (Sj18) for performing the process of enabling the operation of the stop switch corresponding to the rotating reel, based on the detection signals of various switches After sequentially executing the switch input determination process (Sj19) for determining whether or not these various switches satisfy the detection condition, the register saved in the stack area in Sj2 is restored (Sj20), and the index prohibited in the step of Sj1 is restored. The interrupt is permitted (Sj21), and the process returns to the state before the interrupt.

  If the timer interrupt is 4 in step Sj16, the stop position is determined from the stop operation position when it is determined that the stop switches 8L, 8C, and 8R are detected, and the number of steps after which the stop should be calculated is calculated. Stop switch process (Sj22), the number of steps until the stop calculated in the stop switch process is counted, stop process (Sj23) to start braking by two-phase excitation when it is time to stop, brake in the stop process After executing the final stop process (Sj24) for three-phase excitation after a certain time from the start, the registers saved in the stack area in Sj2 are restored (Sj20), and the interrupts prohibited in the step of Sj1 are permitted. (Sj21), the process returns to the state before the interruption.

  FIG. 26 is a flowchart showing the control content of the stop switch process executed by the CPU 41a in the timer interrupt 4 of the timer interrupt process described above.

  In the stop switch process, first, it is determined whether or not a stop operation has been detected for all reels in the order of left, middle and right (Sk1, Sk2). If no stop operation has been detected for all reels, The stop switch process is terminated, and the process returns to the flowchart of FIG.

  If a stop operation of any reel is detected in the step of Sk1, the stop control position corresponding to the reel is referred to and the stop operation position set for the work corresponding to the stop reel is determined. The area number to be the stop position is specified from the area number including the number of steps (Sk3), and the number of steps required from the current reel reference position to the stop position specified in the Sk3 step is calculated. After the set number of steps is set (Sk4), the stop switch process is terminated and the process returns to the flowchart of FIG.

  FIG. 27 shows the control contents of the interruption interrupt process executed by the CPU 41a in response to the occurrence of the interruption 2, that is, when the voltage drop signal from the interruption detection circuit 48 is inputted, and interrupting the execution process or the game process. It is a flowchart which shows.

  In the power interruption interruption process, first, interruption is prohibited (Sm1). That is, other interrupt processing is prohibited from being executed at the start of the power interruption interrupt processing. Next, all registers that may be in use are saved in the stack area (Sm2). Note that the values of the I register and IY register described above are used, but are not saved here because the same fixed value is always set with the initialization at the time of startup.

  Next, the detection data of the voltage drop signal is acquired from the input port, and it is determined whether or not the voltage drop signal is input (Sm3). At this time, if the voltage drop signal is not inputted, the register saved in the stack area in Sm2 is restored (Sm4), the interrupt prohibited in the step of Sm1 is permitted (Sm5), and the process before the interrupt is performed. Return.

  If a voltage drop signal is input in step Sm3, destruction diagnosis data (5A (H) in this embodiment) is set (Sm6), and all output ports are initialized (Sm7). . Next, RAM parity adjustment data is calculated and set so that the exclusive OR of all storage areas (including unused areas and unused stack areas) of the RAM 41c becomes 0 (Sm8), and access to the RAM 41c is performed. It is prohibited (Sm9).

  Then, except for the determination of whether or not the voltage drop signal is input (Sm10, where Sm10 is the same process as Sm3), a loop process in which no process is performed is entered. That is, when the voltage decreases as it is, the operation is stopped internally. Therefore, the CPU 41a reliably stops operation when the power is interrupted. Further, in this loop processing, when the voltage recovers and the voltage drop signal is not input, the above-described startup processing is executed, and if the RAM parity is 0 and the destructive diagnosis data is normal, the original processing is performed. It will return to.

  In this embodiment, after the access to the RAM 41c is prohibited, the output state of the voltage drop signal is monitored, and when the voltage drop signal is not input, it is determined that the voltage is restored, and the process proceeds to the startup process. However, no processing is performed in the loop processing, and the voltage is recovered while the loop processing is being performed, and the process proceeds to the start-up processing based on the input of the reset signal from the reset circuit 49. You may make it do.

  Next, various control contents executed by the CPU 91a of the sub-control unit 91 mounted on the effect control board 90 will be described based on the flowcharts of FIGS.

  In the startup process (sub), after initialization of the built-in device, peripheral IC, interrupt mode, stack pointer, etc. (Sn1), access to the RAM 91c is permitted (Sn2). Then, the RAM parity of all the storage areas of the RAM 91c is calculated (Sn3), and it is determined whether or not the RAM parity is 0 (Sn4). If the data in the RAM 91c is normal, the RAM parity should be 0. If the RAM parity is 0 in the Sn4 step, the data stored in the RAM 91c is normal, so the process proceeds to the Sn5 process. The production state before power interruption is restored. In the step of Sn5, the control pattern executed before the power interruption is set, and the value of the chance counter set in the RAM 91c is initialized (updated to 0) (Sn6). Then, according to the control pattern set in the step of Sn5, an effect control process for controlling various effect devices such as the liquid crystal display 51, effect effect LED 52, speakers 53 and 54, and reel LED is executed (Sn7) and interrupted. Is permitted (Sn8) and the process proceeds to loop processing.

  Further, if the RAM parity is not 0 in the step of Sn4, the data stored in the RAM 91c is not normal. Therefore, after the RAM 91c is initialized (Sn9), the standby pattern is set as the control pattern (Sn10). The value of the chance eye counter set in the RAM 91c is initialized (updated to 0) (Sn6), and according to the control pattern set in the step of Sn10, the liquid crystal display 51, effect effect LED 52, speakers 53 and 54, reel An effect control process for controlling various effect devices such as LEDs is executed (Sn7), an interrupt is permitted (Sn8), and the process proceeds to a loop process.

  FIG. 29 is a flowchart showing the control contents of the timer interrupt process (sub) executed by the CPU 91a at intervals of 1.12 ms based on the count of the internal clock.

  In the timer interrupt process (sub), first, it is determined whether or not a command is stored in the buffer, that is, whether or not a command is received from the main control unit 41 (Sp1). If no command is stored in the buffer, the process proceeds to step Sp8. If a command is stored in the buffer, the command is acquired from the buffer (Sp2), and the process proceeds to step Sp3.

  In the step of Sp3, a continuous effect process for executing a continuous effect is executed in accordance with the received command, and the process proceeds to the step of Sp4.

  In the step of Sp4, when the received command is a reel stop command, the stop sound A, the winning status of the game, the winning status of the combination, the stop reel indicated by the reel stop command, the stop operation position, and the stop position are determined. A stop sound setting process for setting a control pattern for outputting either one of the stop sounds B in the RAM 91c is executed, and the process proceeds to step Sp5.

  In step Sp5, it is determined whether or not an effect pattern for continuous effects is set in the RAM 91c. If an effect pattern for continuous effects is not set, the effect table stored in the ROM 91b is referred to, An effect pattern is selected at a selection rate corresponding to the result of the internal lottery indicated by the winning command, an effect pattern selection process is performed in which the selected effect pattern is set in the RAM 91c as the effect pattern of the game, and the process proceeds to step Sp6.

  In the step of Sp6, referring to the control pattern table stored in the ROM 91b, the control pattern setting for reading the effect pattern set in the RAM 91c and the control pattern registered corresponding to the acquired command and setting it in the RAM 91c The process is executed, and the process proceeds to step Sp7.

  In the step of Sp7, in accordance with the control pattern set in the steps of Sp4 and Sp6, an effect control process for controlling various effect devices such as the liquid crystal display 51, effect effect LED 52, speakers 53 and 54, and reel LED is executed. Proceed to step Sp8.

  In the step of Sp8, after updating the values of various counters such as a random number counter of the RAM 91c, the process proceeds to the step of Sp9. In the step of Sp9, the content of data backed up in the RAM 91c at the time of activation is normal. Thus, the RAM parity adjustment data is calculated and set so that the exclusive OR of all the storage areas of the RAM 91c becomes 0, and the timer interrupt process (sub) is terminated.

  That is, the CPU 91a does not set the RAM parity adjustment data when the power interruption is detected like the CPU 41a of the main control unit 41, but the RAM parity adjustment data for each timer interrupt process (sub) that is periodically executed. Even if the power is cut off, it is possible to determine whether or not the content of the data backed up in the RAM 91c at the time of recovery is normal.

  30 and 31 are flowcharts showing the control contents of the continuous effect process executed by the CPU 91a in the step Sp3 of the timer interrupt process (sub).

  In the continuous effect process, first, it is determined whether or not the received command is a game state command (Sq1). When the game state command is received, the game state of the next game is set (Sq2), and the continuous effect process is performed. Then, the process returns to the flowchart of FIG.

  If it is not a game state command in the step of Sq1, it is determined whether or not the game state of the game is a normal game state (Sq3). Returning to the flowchart, if it is the normal gaming state, it is determined whether or not the continuous effect is being executed based on whether or not the continuous effect flag indicating that the continuous effect is being executed is set (Sq4).

  If the continuous effect is being executed in step Sq4, it is determined whether or not the received command is a winning determination command (Sq5). If it is not the winning determination command, the continuous effect process is terminated, and the flowchart of FIG. If it is a winning determination command, it is determined whether or not any bonus has been won based on the contents of the command (Sq6). If any bonus has not been won, the continuous effect process is terminated. Returning to the flowchart of FIG.

  If any bonus has been won in step Sq6, the continuous effect flag is cleared (Sq7), the continuous effect process is terminated, and the process returns to the flowchart of FIG.

  If the continuous effect is not being executed in step Sq4, it is determined whether or not the received command is an internal winning command (Sq8). If the command is an internal winning command, 1 is subtracted from the value of the chance eye counter ( Sq9) It is determined whether or not the bonus has already been notified (Sq10). If the bonus has not been notified, whether or not the value of the chance eye counter exceeds 0, that is, the appearance rate of the chance eye in the normal gaming state is It is determined whether or not 1/300 is exceeded (Sq11). If the chance rate in the normal gaming state exceeds 1/300, a low probability flag is set (Sq12). If the chance rate in the normal gaming state is 1/300 or less, a high probability flag is set. A probability flag is set (Sq13).

  Next, a continuous effect lottery for determining whether or not to execute a continuous effect is executed (Sq14). In the continuous effect lottery, when no bonus is won and the low probability flag is set in the step of Sq12, that is, when the appearance rate of chance chances in the normal gaming state exceeds 1/300, 3 When the winning probability of 1993 is applied and none of the bonuses are won, and when the high probability flag is set in the step of Sq13, that is, the appearance rate of chance eyes in the normal gaming state is 1/300 or less The winning probability of 10/1993 is applied, and if any bonus is won, the winning probability of 350/1993 is applied.

  Next, it is determined whether or not the continuous production lottery is won (Sq15). If the continuous production lottery is won, the continuous production lottery flag is set (Sq16), and the continuous production process is terminated. Returning to the flowchart of FIG. If the continuous effect lottery is not won in step Sq15, the continuous effect process is terminated as it is, and the process returns to the flowchart of FIG.

  If the received command is not an internal winning command in step Sq8, or if it is determined in step Sq10 that a bonus notification has been made, it is determined whether the received command is a reel stop command (Sq17). If it is not a reel stop command, the continuous effect process is terminated and the process returns to the flowchart of FIG. 29. If it is a reel stop command, it is further determined whether or not all reels are stopped (Sq18). Even if is not stopped, the continuous effect process is terminated and the process returns to the flowchart of FIG.

  If all the reels are stopped in step Sq18, it is determined whether or not the continuous effect is won based on whether or not the continuous effect winning flag is set (Sq19). If it is won, the process proceeds to step Sq23.

  If the continuous effect is not won in step Sq19, it is determined whether or not the chance eye has stopped (Sq20). If the chance eye has not stopped, the continuous effect processing is terminated, Returning to the flowchart of 29, if the chance eye has stopped, 300 is added to the value of the chance eye counter (Sq21), and it is determined whether or not the bonus has already been announced (Sq22). If the bonus has been notified, the continuous effect process is terminated, and the process returns to the flowchart of FIG. 29. If the bonus has not been notified, the process proceeds to step Sq23.

  In step Sq23, one of the continuous production patterns is selected from a plurality of continuous production patterns at a ratio according to whether or not the bonus is won. Then, the selected continuous effect pattern is set as an effect pattern over a plurality of games (Sq24), and after setting a continuous effect in-process flag indicating that the continuous effect is being executed (Sq25), the continuous effect process is terminated. Return to the flowchart. The continuous effect flag is cleared when the continuous effect is ended by the bonus winning or when the continuous effect of the number of games corresponding to the continuous effect pattern is ended.

  As described above, in the slot machine 1 of the present embodiment, a plurality of control tables in which stop positions are uniquely determined with respect to stop operation positions (areas assigned to the number of steps from the reel reference position). Among them, when all the reels are rotating, a stop control table uniquely determined for the winning situation of each role in each gaming state is selected, and the reel stop control is performed according to the selected stop control table. When one of the reels is already stopped, a stop control table uniquely determined for the winning status of each of the game states and the stop operation position of the stopped reel The reel stop control is performed according to the selected stop control table, and the gaming state, winning status of the combination, reel stop When all of the situations (and stopping operation positions of the stopped reels) are the same, the reel stop control is performed based on the same stop control table, that is, the same control pattern. There is no need to further select any one of the control patterns, and the control for stopping the reel does not become complicated.

  In addition, when any bonus is won in the normal gaming state, more stop operation positions are defined as conditions for deriving chance chances than when no combination is won in the normal gaming state. Since the reels are controlled according to the stop control table, if any bonus is won in the normal gaming state, the chance is higher than when no combination is won in the normal gaming state. Since the eyes are derived, and the chance eyes are derived, it is possible to increase the player's expectation for winning the bonus. For this reason, the interest by the display result of a reel can be heightened, without complicating the control at the time of stopping a reel.

  In this embodiment, the chance that is established when the display result is derived for all reels is applied, but it is established when the display result is derived for any one reel or two reels. Opportunities may be applied, for example, a display mode that is established only by deriving a “watermelon” symbol at a specific position on the left reel, or on a specific winning line when the left reel and the middle reel are stopped A display mode that is established only by deriving the “watermelon” symbol may be applied as an opportunity.

  In addition, when applying the chance that is established when the display result is derived for any one reel, if any bonus is won in the normal gaming state, any role in the normal gaming state is selected. In the normal gaming state, by selecting a stop control table in which more stop operation positions are set as stop positions where chances are established than when not winning, and performing control to stop the reels according to this stop control table If one of the bonuses is won, chances will be derived at a higher rate than if no combination is won in the normal gaming state. Can increase the player's expectation of winning. Even in such a case, it is possible to enhance the interest by the display result of the reel without complicating the control when stopping the reel.

  In this embodiment, the chances are derived on the condition that the reel stop operation is performed in the order of left, middle, and right, but other orders, for example, left, middle, etc. The chances may be derived on the condition that the reel stop operation is performed in the order of left, right, and center in addition to the order of the right, or in the order in which the reel stop operation is performed. Regardless of the chance, the chance may be derived.

  Further, in this embodiment, when any of the reels is already stopped, the stop determined uniquely with respect to the winning situation of each combination in each gaming state and the stop operation position of the stopped reel Reel stop control is performed according to the control table, even if the game status and winning status of the combination are the same, and the stop position (stop symbol) of the stopped reel is the same, stop Since different stop control tables may be applied when the stop operation positions of the reels are different, the display results of the reels can be made more diverse.

  In particular, when none of the roles is won in the normal gaming state (losing), the left reel is configured even if a stop operation is performed in any of the area numbers 16 to 23. The “watermelon” symbol stops at the lower or middle stage, and the stop operation was performed in any of the area numbers 4, 5, 12, 13, 20, 21, 23, 34 to 39, 41 on the middle reel. Even in this case, the “watermelon” symbol constituting the chance eye stops in the middle, but on the left reel, the stop operation was performed in the area numbers 17, 19, 21, and 23 of the area numbers 16 to 23. On the condition, a stop control table capable of deriving a chance is selected as the stop control table for the rotating reel. For the middle reel, the region numbers 4, 5, 12, 13, 20, 21, 23, 34 to 39 are selected. 41, a stop control table capable of deriving a chance is selected as a stop control table for the spinning reel, on condition that a stop operation has been performed in the regions of region numbers 23 and 41. When the stop position of the left reel when the left reel is stopped, or the stop position of the left reel and the middle reel when the left reel and the middle reel are stopped is the same as the stop position from which the chance chance is finally derived Even if the stop operation position is different, however, the chances may not be derived in the end, so the reel display result is monotonous when none of the roles are won in the normal gaming state (losing). Can be prevented.

  Further, in this embodiment, the stop operation position of the stopped reel is determined in an area in which the 1/2 symbol varies, that is, in a unit less than the range in which one symbol varies, and is unique to the stop operation position. The reel stop control is performed in accordance with the stop control table defined in (1). That is, it is possible to select different stop control tables for different number of steps within the range in which one symbol fluctuates from the number of steps where a certain symbol is located at the reference position, and the stopped position of the stopped reel is the same. Even if the timing at which the stop operation is performed is within the range in which one symbol fluctuates, the stop control table applied to other reels can be changed, so that the display results of each reel are further diversified. be able to.

  In this embodiment, at the time of starting the rotation of the reels, a stop control table uniquely determined with respect to the winning situation of each game state is selected for all the reels, and the selected stop control table is selected. The reel stop control is performed according to the following, and each time the reel is stopped, for each spinning reel, the winning status of each of the game states and the stop operation position of the stopped reel, that is, any one of the reels A stop control table uniquely defined for a combination of stop operation positions of stopped reels when the reels are stopped, and stop operation positions of two stopped reels when any two reels are stopped The reel stop control is performed according to the selected stop control table. For example, any one of them is controlled. When the reels of the reels are stopped, for the spinning reels, a winning control status for each of the gaming states is selected, and a stop control table uniquely determined for the stop operation position of the stopped reels is selected. The reel stop control is performed according to the selected stop control table, and when one of the reels stops (when two reels stop), no new stop control table is selected and all the reels rotate. The remaining reels may be controlled to stop according to the stop control table selected when any one of the reels is stopped in this state.

  Further, when any one reel is stopped, for the spinning reel, a winning control for each game state, a stop control uniquely determined for the stop operation position of the stopped reel Select a table, perform reel stop control according to the selected stop control table, and when one of the reels stops (when two reels stop), the winning status of each of the game states Alternatively, a stop control table uniquely determined for the stop operation position of the reel that has stopped last may be selected, and the reel stop control may be performed according to the selected stop control table.

  In addition, in this embodiment, when any two reels are stopped, the winning combination of each game state for each spinning reel is unique to the combination of the stop operation position of the stopped reel. The stop control table defined in (1) is selected, and the reel stop control is performed according to the selected stop control table.For example, when any two reels stop, Uniquely with respect to the winning status of each role in each gaming state, the stop operation position of any one of the stopped reels, and the stop position (display result) of the remaining reels of the stopped reels A predetermined stop control table may be selected, and reel stop control may be performed according to the selected stop control table.

  Further, when any one reel is stopped, a stop control table uniquely determined with respect to the spinning reels for the winning status of each of the game states and the stop operation position of the stopped reels When any two reels are stopped, the stop control uniquely determined for the combination of the winning combination of each game state and the stop position (display result) of the stopped reels A table may be selected, and reel stop control may be performed according to the selected stop control table.

  In addition, when any one reel is stopped, it is uniquely determined with respect to the spinning reel, with respect to the winning situation of each combination in each gaming state, and the stop position (display result) of the stopped reel. When a stop control table is selected and any two reels stop, the winning control uniquely determined for the combination of winning combination status of each gaming state and stop operation position of the stopped reel A table may be selected, and reel stop control may be performed according to the selected stop control table.

  Further, when any one reel is stopped, a stop control table uniquely determined with respect to the spinning reels for the winning status of each of the game states and the stop operation position of the stopped reels When any two reels are stopped, the winning status of each combination in each gaming state, the stop operation position of one of the stopped reels, the remaining of the stopped reels A stop control table uniquely determined for the stop position (display result) of the reel may be selected, and the reel stop control may be performed according to the selected stop control table.

  In addition, when any one of the reels is stopped, a stop control table uniquely determined with respect to the spinning reel is determined for the winning status of each of the game states and the stop position of the stopped reel. When any two reels are stopped, the winning status of each combination in each gaming state, the stop operation position of one of the stopped reels, the remaining of the stopped reels A stop control table uniquely determined for the reel stop position (display result) may be selected, and the reel stop control may be performed according to the selected stop control table.

  In these cases, when a stop control table uniquely determined for a stop operation position or a combination of stop operation positions is selected, a unit less than the range in which one symbol fluctuates (for example, a step number unit) ) To determine the stop operation position of the stopped reel, and to perform the stop control of the reel according to the stop control table uniquely determined for the stop operation position or the combination of the stop operation positions. By doing so, it is possible to select different stop control tables for different number of steps within the range in which one symbol fluctuates from the number of steps at which a certain symbol is positioned at the reference position, and the stop position of the stopped reel Even if the timing when the stop operation is the same is within the range where one symbol fluctuates, the stop control table applied to other reels It is possible to change, it is possible to further diversify the display result of the reels.

  Further, in this embodiment, when any of the reels has already stopped, the winning combination status for each gaming state, the stop operation position of the stopped reel, or a combination of the stop operation positions is unique. The reel stop control is performed in accordance with the stop control table that is determined in a specific manner, but when any one of the reels is already stopped, the spinning reel is A stop control table uniquely determined for the winning status of the combination and the stop position (display result) of the stopped reel is selected, and the stop control of the reel is performed according to the selected stop control table. Is already stopped, for the spinning reel, the winning status of each role in each gaming state, the stop position of the stopped reel (Display result) combining select uniquely stop control table defined with respect to the, may be performed reel stop control in accordance with the stop control table selected. As a result, if the gaming state and the winning status of the combination are the same and the stop position of the stopped reel is the same, the same stop control table is always applied. The capacity of table creation data for creation can be reduced.

  In addition, when any one reel stops, it is uniquely determined with respect to the spinning reel with respect to the winning status of each game state and the stop position (display result) of the stopped reel. The selected stop control table is selected, and reel stop control is performed according to the selected stop control table. When one of the reels stops (when two reels stop), a new stop control table is selected. Instead, stop control of the remaining reels may be performed according to the stop control table selected when any one of the reels is stopped while all the reels are rotating.

  In addition, when any one reel stops, it is uniquely determined with respect to the spinning reel with respect to the winning status of each game state and the stop position (display result) of the stopped reel. The selected stop control table is selected, and reel stop control is performed in accordance with the selected stop control table. Further, when one of the reels stops (when two reels stop), the role for each game state is selected. It is also possible to select a stop control table that is uniquely determined for the winning status and the stop position (display result) of the last stopped reel, and to perform the reel stop control according to the selected stop control table.

  Even in these cases, if any bonus is won in the normal gaming state, the stop position that is a condition from which a chance is derived compared to the case where no combination is won in the normal gaming state If a stop control table with a large number of stop operation positions to be selected is selected and control is performed to stop the reels according to the stop control table, and if any bonus is won in the normal gaming state, the normal game In the state, chances are derived at a higher rate than when no combination is won, and the chances are derived, so that the player's expectation for winning the bonus can be enhanced. Even in such a case, it is possible to enhance the interest by the display result of the reel without complicating the control when stopping the reel.

  Also, in this embodiment, when no combination is won in the normal gaming state, a stop control table that defines a stop operation position from which chance chances can be derived is selected. In the state, when a specific small role has been won and other roles have not been won, in addition to the stop operation position that draws the symbol corresponding to the selected small role, a stop operation position that is a derivation condition for the chance ( For example, by selecting a stop control table that defines the “stop operation position that draws the“ watermelon ”symbol that constitutes the chance eye”, a specific small role is won and a stop corresponding to the small role cannot be drawn When a stop operation is performed at the operation position and a stop operation is performed at the stop operation position that is a condition for deriving the chance, that is, when a specific small role is won and the small role is missed (example) For example, if you win the cherry and the left reel is stopped at the stop position where the “cherry” symbol cannot be drawn on the winning line of the left reel, the “cherry-cherry-cherry” combination is also reduced. When a winning combination is applied, the winning combination is won, and the “Cherry” symbol is not drawn on the winning line with one of the reels, etc.) In this way, when a specific small role is elected and when the small role is missed, a chance item is derived, and the appearance of the chance item is a specific small item. Since it depends on the winning of the role, the appearance of the chance eyes can be dispersed moderately. In addition, since the chance rate of chances in the situation where the bonus is not won in the normal gaming state can be lowered, the possibility that one of the bonuses has been won increases when the chance is derived. Deriving the eyes can increase the player's expectation for winning the bonus.

  In addition, in a normal gaming state, when a specific small combination is won and no other combination is won, the symbol corresponding to the selected small combination does not stop for at least one of the reels. By selecting a stop control table that defines a stop operation position (for example, a stop operation position for drawing a “watermelon” symbol constituting the chance eye) as a chance eye derivation condition for a reel that is still rotating, When a small role is elected and a stop operation is performed at a stop operation position where one of the reels cannot withdraw the symbol corresponding to the small role, that is, a specific small role is won and the small role is missed. The chance result may be established based on the display result derived on the other reels. Even in this case, a specific small role is won and the small role is selected. In the event of a spill, chances will be derived, and the appearance of chances will depend on the winning of a specific small role. The chances of appearing in a gaming state where a bonus is not won can be lowered, so when a chance is derived, the chance of winning one of the bonuses increases and the chance is derived By doing so, it is possible to increase the player's expectation for winning the bonus.

  Further, in this embodiment, the number of frames to be drawn (a stop position when a stop operation is detected in the range) for each of a plurality of consecutive step number ranges (in this embodiment, four steps each having a 1/2 symbol change). Since the stop control of the reel is performed using the stop control table uniquely determined), the capacity of the table creation data for creating the stop control table can be greatly reduced.

  Furthermore, in the present embodiment, a stop control table in which the number of frames to be drawn (stop position) is uniquely determined for each region of the range where the 1/2 symbol fluctuates, that is, the unit less than the range where one symbol fluctuates, is used. The reel stop control is performed. That is, it is possible to perform reel stop control using a stop control table in which different stop positions are set for different number of steps within a range in which one symbol varies from the number of steps at which a certain symbol is located at the reference position. 1 Even if it is within the range where the symbol fluctuates, the display result derived by the timing of the stop operation can be changed, so the display result of the reel in various modes depending on the timing of the stop operation Can be derived.

  Further, in this embodiment, when neither bonus is won in the normal gaming state, when the left reel and the middle reel are stopped, the range in which the 1/2 symbols change (in the left reel, Rotating on condition that the stop operation was performed at the timing within the range where the area numbers 17, 19, 21, 23, and the area of the middle reel are the area numbers 23 and 41), that is, one symbol fluctuates. A stop control table from which chances can be derived is selected as the reel stop control table. That is, when the stop operation of the left reel and the middle reel is performed, the control for deriving the chance is performed on the condition that the stop operation is performed at a timing within a range where one symbol fluctuates. When no bonus is won in the normal gaming state, it is possible to reduce the rate at which chances are derived as much as possible, and when the chance is derived, either bonus is won. Since the chance is derived, it is possible to effectively increase the player's expectation for the bonus.

  In this embodiment, when no bonus is won in the normal gaming state, when the left reel and middle reel are stopped, the stop operation is performed at a timing within the range where one symbol fluctuates. However, when the stop operation is performed on at least one reel, the stop operation is performed at a timing within a range where one symbol fluctuates. If the control for deriving the chance is performed on the condition, the same effect can be obtained, and the stop operation is performed at a timing within a range where one symbol fluctuates for any one reel. On the condition that the chance is derived, or for any two or more reels, the stop operation is performed at a timing within a range where one symbol fluctuates. The chances are derived on the condition that the control for deriving the chance is performed on the condition that the operation is performed, and that the stop operation is performed at the timing within the range where one symbol fluctuates for all reels. Even if the control is performed, the same effect as described above can be obtained.

  Further, in this embodiment, when neither bonus is won in the normal gaming state, when the left reel and middle reel are stopped, the stop operation is performed at a timing within a range where one symbol fluctuates. By selecting a stop control table that can derive chances for the remaining reels on the condition that the failure has occurred, the chances are obtained on the condition that the stop operation has been performed at a timing within the range where one symbol fluctuates. For example, for at least one of the reels, a chance operation established at the time when the reel is derived, or a stop operation position for drawing in a symbol constituting the chance eye, By selecting a stop control table that is determined so as not to continue beyond the range where one symbol fluctuates, the timing within the range where one symbol fluctuates is selected. Control may be made to derive chances on the condition that a stop operation is performed in the game, and even in such a case, in the case where no bonus is won in the normal gaming state , It is possible to reduce the rate at which chances are derived as much as possible and increase the chances of winning one of the bonuses when chances are derived. By doing so, it is possible to effectively increase the player's expectation for the bonus.

  Also, different stop control tables are used for cases where no combination is won in the normal gaming state and when any bonus is won in the normal gaming state and other combinations are not won. When deriving chances for the left reel and the middle reel to be used, one of the bonuses is won in the normal gaming state and other than in the case where no role is won in the normal gaming state If you are not selected for the role, the average number of draws will be larger, and when deriving chances, the amount of fluctuation from when the stop operation is performed until the corresponding reel stops will be larger When a chance is derived, the bonus can be chosen as the amount of change from the reel stop operation to the actual stop increases. Since the increases, it is possible to increase the interest associated with that chance eyes is derived more.

  In this embodiment, when deriving a chance, the player wins any bonus in the normal gaming state and wins other bonuses than when no role is won in the normal gaming state. If you do not win, you use a stop control table that has a larger average number of draws, but if you do not win any role in the normal gaming state or in the normal gaming state If you use a stop control table with a different average draw-in number when you win the bonus of the other and you do not win for any other role, you can use the reel stop operation when deriving the chance Since the possibility of winning the bonus varies depending on the amount of change from when it is actually performed to when it stops, it is possible to further enhance the interest associated with the chances being derived.

  In the present embodiment, the continuous performance is executed when the chance is derived. In other words, since the continuous performance is executed in relation to the derivation of the chances that are likely to be won by the bonus, the player's expectation for the bonus is expressed by both the reel display result and the performance related to the display result. Can be increased.

  In addition, according to the stop control table uniquely determined for the winning status of the combination for each game state and the stop status of the reel (and the stop operation position of the stopped reel or the stop position of the reel) When performing stop control, for example, when the player performs a stop operation at a timing other than the stop operation position at which a chance eye can be derived, and the game is performed by performing a stop operation, the rate at which the chance eye is derived is extremely reduced. However, in this embodiment, a continuous effect lottery is executed in each game in the normal gaming state, and a continuous effect is also executed when winning the continuous effect lottery. That is, even when the chance is not derived, if the continuous production lottery is won, the continuous production is executed. For this reason, even when the rate at which chance chances are derived is extremely reduced, a continuous effect is appropriately executed, so that a player's expectation on the bonus can be effectively increased.

  Further, in this embodiment, when no bonus is won in the normal gaming state, the chance rate of appearance is predetermined when the chance rate of appearance is less than a predetermined ratio (1/300). The continuous production lottery is performed with a higher win probability than when the ratio exceeds (1/300), and the appearance rate of chances, that is, the frequency of execution of continuous productions when the chances are derived If the number is extremely reduced, the continuous effect is executed with a high probability, and therefore, the continuous effect can be executed at an appropriate rate in the appearance history of the chances until then.

  In this embodiment, when the chance chance is derived, that is, when the combination of the display results of all reels becomes the chance eye, a continuous effect, that is, a specific effect is executed. When applying the chance that is established when one of the reels is stopped, if any one of the reels is stopped and the chance is established, the specific effect is executed from that point. Anyway.

  Further, in this embodiment, a continuous effect over a plurality of games is applied as a specific effect to be executed when a chance item is derived. It is also possible to apply as a specific effect. An effect executed between the time when the chance is derived and the start of the next game may be applied.

  In this embodiment, each time the reels stop, the reel to be stopped is any one of the left reel, the middle reel, and the right reel, the area number of the stop operation position of the corresponding reel, and the stop position of the corresponding reel. Since the reel stop command capable of specifying the area number is transmitted to the sub-control unit 91, the CPU 91a of the sub-control unit 91 stops the reel when the reel stops. In addition, it is possible to perform different effects according to the stop operation position.

  In particular, in this embodiment, when no combination is won in the normal gaming state, when the left reel and the middle reel are stopped, the stop position of the left reel and the middle reel is finally derived as a chance. Even if it is the same as the stop position, if the stop operation position of the left reel and the stop operation position of the middle reel do not satisfy the chance eye derivation condition, the chance eye is not finally derived. When the reel stop command is received and the stop operation position satisfies the chance derivation condition, the stop operation position does not satisfy the chance derivation condition, but the display result is such that the chance eye can be derived. Control for outputting the stop sound B at a higher rate is performed. For this reason, when the left reel and the middle reel are stopped, even if the same display result is obtained, there is a possibility that the chance chance is finally derived when the stop sound B is output rather than the stop sound A is output. As the stop sound B is output, it is possible to effectively increase the player's expectation for the derivation of the chance and the bonus winning.

  Also, in this embodiment, when each reel is stopped, the stop sound is played at a higher rate when one of the bonuses is won in the normal gaming state than when no combination is won. Since B is output, it is more likely that one of the bonuses is won when the stop sound is output than when the stop sound A is output when each reel is stopped. As the number of reels to which is output increases, the possibility of winning one of the bonuses increases. Therefore, the expectation of winning the bonus can be more effectively enhanced by the change in the stop sound.

  In this embodiment, when the reel stop command is received, that is, when the reel is stopped, either the stop sound A or the stop sound B is output, and the stop operation position is satisfied when the stop operation position satisfies the chance derivation condition. Although the operation position does not satisfy the derivation condition of the chance eye, the control is performed to output the stop sound B at a higher rate than the display result that the chance eye can be derived. When receiving, that is, when the reel is stopped, when the stop operation position satisfies the chance derivation condition, the stop operation position does not satisfy the chance derivation condition, but the display result is that the chance eye can be derived. However, the production mode other than the stop sound (for example, the lighting mode of the lamp or LED, the display mode of the liquid crystal display 51) is different from the usual. That in the case of the control to change the representation embodiment, the same effect as changing the reel stop sound is obtained.

  In the present embodiment, the reel stop sound output when the reel is stopped, that is, the type of effect performed when the reel is stopped, is selected at a different rate depending on the stop operation position. The type of effect performed at the time of stoppage may be selected at a different rate depending on the stop operation position of the reel that has already stopped before the reel stops. Different effects can be performed depending on not only the position but also the stop operation position.

  Further, in this embodiment, when the player operates the stop switches 8L, 8C, 8R, the symbol to be stopped is selected according to the winning status of the combination and the timing of the stop operation, and the display result is derived on the reel. Is done. In other words, winning is generated not only by the winning situation of the role but also by the player's technical intervention of operation of the stop switches 8L, 8C, 8R, so that the winning is prevented only by the chance factor. Security of sex will be secured. In addition, regardless of the time that the player has not operated the stop switches 8L, 8C, 8R, the rotation of the reels for which the stop operation has not yet been detected is detected until the operation of the stop switches 8L, 8C, 8R is detected. Since the display result is derived to the corresponding reel on condition that the operation of the stop switches 8L, 8C, and 8R is detected, the player does not operate the stop switches 8L, 8C, and 8R. Thus, the display result is not derived only by the contingency element that time has passed, and it is possible to ensure the suppression of shooting characteristics.

  Further, in this embodiment, when an abnormality occurs in the data stored in the RAM 41c, the error state due to the RAM abnormality error is controlled, the progress of the game is disabled, and the error state once caused by the RAM abnormality error. If it is controlled, the state in which the progress of the game is disabled will not be released unless the setting change mode is entered and the setting value is newly selected and set based on the setting changing operation. That is, even if an abnormality occurs in the data stored in the RAM 41c, it is not the setting value automatically set by the slot machine, but the setting value selected and set based on the setting change operation (generally, the setting change Since the operation is performed by an employee of the amusement store, it is ensured that the game is performed based on the setting value selected by the amusement store side), so that the fairness of the game can be achieved.

  Further, in this embodiment, when determining whether or not winning is allowed in the internal lottery process, the set value stored in the set value work of the RAM 41c is an appropriate value (a value in the range of 1 to 6). If not, it is not determined whether or not the winning is allowed with the probability based on the default setting value (for example, setting 1). If the progress is disabled, the mode is changed to the setting change mode, and the setting value is not newly selected / set based on the setting change operation, the state where the progress of the game is disabled is not released. In other words, it is guaranteed that the game will be played based on the setting value selected and set based on the setting change operation even when it is not possible to properly determine whether or not the winning is allowed in the internal lottery process. Therefore, the fairness of the game can be achieved.

  Further, the data stored in the RAM 41c is abnormal in most cases when the control cannot be continued due to a malfunction such as a power failure or the CPU 41a running out of control. For this reason, in this embodiment, since it is determined whether or not the data is normal only when the CPU 41a is activated after recovering from these states, it is determined whether or not the data stored in the RAM 41c is normal. The determination can be made only in a situation where there is a high possibility that an abnormality has occurred in the data. That is, in a situation where there is a low possibility that an abnormality has occurred in the data, it is not necessary to perform the determination, and the load on the CPU 41a can be reduced.

  In this embodiment, the RAM parity adjustment data is calculated and stored so that the result of the exclusive OR operation is 0 based on all the data in the RAM 41c in the power interruption processing, that is, Since it is determined whether or not the data in the RAM 41c is normal by determining whether or not the RAM parity calculated based on the data stored in all the areas in the RAM 41c at the time of recovery is 0, the determination is made as follows. It can be performed accurately and conveniently.

  Further, in this embodiment, in the power interruption interrupt processing, destruction diagnosis data (in this embodiment, 5A (H)) in which any bit is 1, that is, specific data other than 0 is stored in the RAM 41c according to a predetermined data. After storing in the address, adjustment data based on all the RAM 41c data including the destructive diagnosis data is stored so that the RAM parity becomes 0. In addition to determining whether or not the RAM parity is 0 at the start, It is determined whether or not the diagnostic data is stored normally, and it is determined that the data in the RAM 41c is normal on the condition that the RAM parity is 0 and the destructive diagnostic data is also stored normally. The control state is restored based on the data stored in the RAM 41c. As a result, when 00 (H) is stored in all areas, that is, when the data in the RAM 41c is cleared to 0 even if the data in the RAM 41c is not normal, the determination of the RAM parity at the time of startup is performed. However, if the data in the RAM 41c has been cleared to 0, the area in which the destructive diagnosis data is to be stored is also 0, and it is determined that the data in the RAM 41c is not normal. Since it can be prevented that the data in the RAM 41c is erroneously determined to be normal, it is possible to further increase the accuracy of determining whether or not the data in the RAM 41c has the correct contents at the time of activation.

  Further, when the CPU 41a determines that the RAM parity is 0 at startup and the data for destructive diagnosis is also normally stored, and determines that the data in the RAM 41c is normal, the destructive diagnosis stored in the RAM 41c. Since the data for destruction diagnosis is still stored in the RAM 41c even after the activation, the data in the RAM 41c is not normal at the next activation, but the data is destroyed. Since diagnostic data is stored, it is possible to prevent erroneous determination as normal.

  Further, in this embodiment, when an abnormality occurs in the data in the RAM 41c and the progress of the game is disabled, a setting value changing operation as a condition for canceling the disabled state of the game is effective. As a result of the transition to the setting change mode (setting change processing), all the areas except the used stack area of the RAM 41c are initialized, so that the initial data of the RAM 41c due to the occurrence of an abnormality And initialization of data associated with selection / setting of set values can be performed at once, and unnecessary processing can be omitted. Further, when the CPU 41a is activated, it is determined whether or not the setting key switch 37 is ON before determining whether the data in the RAM 41c is normal. At that time, the setting key switch 37 is ON. If it is determined that there is, the determination as to whether the data in the RAM 41c is normal is not performed, and the mode shifts to the setting change mode, where a new setting value is selected and set. It can be omitted.

  In this embodiment, initialization 1 for initializing all areas except the used stack area of the RAM 41c is performed before shifting to the setting change process. However, along with the shift to the setting change process. Initialization 1 may be performed, for example, after the setting change process is completed, or may be performed when the setting value is confirmed in the setting change process. In this case, since the inconvenience arises when the determined set value is changed, in initialization 1, all areas except the used stack area and set value work of the RAM 41c are initialized. Become.

  Further, in this embodiment, once the error state due to the RAM abnormality error is controlled, the game is disabled until the setting change process is performed, but the error state due to the RAM abnormality error occurs. When initialization is performed, all areas except the used stack area of the RAM 41c are initialized, and a set value is set to an initial value (for example, set value 1), and a reset operation is performed in this state. Thus, the game may be restarted.

  Further, in this embodiment, when determining whether or not winning is allowed in the internal lottery process, the set value stored in the set value work of the RAM 41c is an appropriate value (a value in the range of 1 to 6). If not, the RAM abnormal error state is also controlled in this case, but the setting value stored in the setting value work of the RAM 41c is not an appropriate value (a value in the range of 1 to 6). In this case, it may be determined whether or not the winning is allowed with the probability based on the initial value of the set value (for example, the set value 1).

  In this embodiment, the CPU 41a transmits a command corresponding to the progress of the game to the effect control board 90, and the sub-control unit 91 mounted on the effect control board 90 receives the command transmitted from the game control board 40. Since the CPU 41a does not need to control the presentation only by sending a command, the processing load on the CPU 41a can be reduced and the presentation can be made various. .

  Further, a command transmission line for transmitting a command from the game control board 40 to the effect control board 90 is connected between the game control board 40 and the effect control board 90 via the effect relay board 80, and the game control board Since the production control board 90 is not directly connected to 40, it is possible to prevent an illegal signal from being input from the command transmission line to the CPU 41a from the outside and affecting the control of the game.

  Further, in this embodiment, when the voltage drop signal is input to the trigger terminal CLK / TRG, the CPU 41a interrupts the process being executed and executes the power interruption process. In the process including the process for setting the data for destructive diagnosis and the process for calculating and setting the data for adjusting the RAM parity, the process for making it possible to determine whether the data in the RAM 41c is normal at the time of recovery or the initial setting of the output port Before performing the conversion, it is determined whether or not a voltage drop signal is input to the signal input terminal DATA. If the voltage drop signal is also input to the signal input terminal DATA, the data in the RAM 41c is normal at the time of recovery. If the voltage drop signal is not input to the signal input terminal DATA, the original processing is performed. It is adapted to return.

  That is, the voltage drop signal is input to the two systems of the input unit to the main control unit 41, and the CPU 41a does not perform the power interruption interrupt process when the voltage drop signal is input to one of the input units. Before the process for enabling determination of whether the data in the RAM 41c is normal, the initialization of the output port, or the like is performed, it is determined again whether or not the voltage drop signal is input to the other input unit. These processes are executed only when a voltage drop signal is also input to the input section of this, and when power failure is detected by mistake, whether or not the data in the RAM 41c is normal at the time of recovery is detected. Since it is possible to prevent the process for enabling the determination and the process such as the initialization of the output port from being performed, the control of the CPU 41a may be interrupted for an unnecessarily long time due to erroneous detection of power interruption. More than necessary Possible to prevent the load is applied to.

  In addition, other interrupts are prohibited during power interruption interrupt processing and timer interrupt processing. For example, when a voltage drop signal is input during execution of timer interrupt processing. However, double interruptions do not occur, and it is possible to prevent the processing load of the CPU 41a from increasing and data consistency from being lost. In particular, even if a voltage drop signal is input during the transmission of a command, no interruption occurs and the transmission of the command is not hindered, and the transmission can be completed normally before the CPU 41a stops driving. .

  Also, if the interrupt timing for power interruption interrupt processing and the interrupt timing for timer interrupt processing are simultaneous, that is, if interrupt 2 and interrupt 3 occur simultaneously, priority is given to interrupt 2 In addition to executing the interruption interrupt process, if an interruption 2 occurs during the execution of the timer interruption process, the interruption interruption process is executed after the timer interruption process ends. Therefore, the power interruption interrupt process is performed as early as possible while preventing multiple interruptions, so that the power interruption interrupt process can be reliably performed before the driving of the CPU 41a is stopped.

  Further, the CPU 41a can execute four types of interrupts of interrupts 1 to 4, and when interrupts 1 and 4 that are set to unused are generated, the CPU 41a immediately returns to the original process. The unused interrupt processing to be executed is executed. For this reason, even if unused interrupts 1 and 4 occur, the process immediately returns to the process before the interrupt. Therefore, even if an unused interrupt occurs due to noise or the like, the CPU 41a runs out of control. It is possible to prevent such troubles.

  In this embodiment, the CPU 91a of the sub-control unit 91 calculates and sets the RAM parity adjustment data every time the timer interrupt process is executed. In other words, the process for making it possible to determine whether or not the content of the data backed up in the RAM 91c at the time of restoration is performed periodically without depending on the command transmitted from the game control board 40. Even when the command is transmitted with a delay, the CPU 91a does not stop before calculating and setting the RAM parity adjustment data due to the delayed transmission of the command. The CPU 91a can accurately determine whether the data backed up in the RAM 91c is normal.

  Further, in the slot machine 1 of the present embodiment, as a type of winning combination, a small role accompanied by paying out medals, a re-playing role that does not require consumption of medals for the number of bets in the next game, and a transition of the gaming state. A special role is provided. The special role is accompanied by a transition of the gaming state and depends on the gaming state at that time, so it cannot be said to be a basic role. The playability of slot machines is not just playing a game, but the player earns medals based on the game results, so the small role that involves paying out medals by winning a prize is the most basic role. It can be said. Here, there are JAC, cherry, and bell as types of small roles, but in addition to JAC that wins with a small probability in the regular bonus, it is determined as a type of winning combination in any gaming state. . In this way, by defining the basic small combination as a winning combination regardless of the gaming state, the gameability becomes easy for the player to understand.

  When a big bonus is won in the normal gaming state, the gaming state is shifted to a big bonus that wins JACIN with a transition to a regular bonus with a relatively high probability (winning because there is no missing). The big bonus is ended when the total number of medals paid out to the player in the big bonus reaches 465 regardless of the number of digest games. Here, in a game with a big bonus (including a small role game and a regular bonus), since replay is not defined as a target character for internal lottery, no replay is won. Replay does not reduce the number of medals held by the player, but does not accompany the payout of medals, and therefore does not affect the number of payout medals, which is a condition for ending the big bonus. In other words, even if you make a replay win during the big bonus, it will only increase the number of big bonus games unnecessarily, so by not defining the replay as a target for internal lottery in the big bonus, The game can be efficiently advanced without unnecessarily prolonging the state.

  In addition, in the regular bonus game state, a small role (especially JAC) is won with a high probability and a large number of medals can be obtained, so the player has high expectations for this. This regular bonus is transferred not only when winning a JACIN in a small role game but also when winning a regular bonus in a normal gaming state. For this reason, even when the player is in the normal gaming state, the player can be given a sense of expectation for the regular bonus, so that the interest of the game can be improved. Furthermore, in the regular bonus, JAC is also defined as a small role in addition to cherry and bell that are also defined in a normal gaming state and a small role game. Thereby, the player's sense of expectation in the regular bonus can be further increased, and the interest of the game can be improved.

  In addition, the display mode of JACIN for shifting the gaming state from the small role game to the regular bonus in the big bonus is configured by a combination of “Bell-Bell-JAC” and is not used as a display mode of other roles. It is. In the regular bonus, the display mode of JAC determined to be a winning in addition to the small role of cherry or bell is also composed of a combination of “replay-replay-JAC” and is not used as a display mode of other roles. . For this reason, the relationship between the display mode derived as the display result of the reels 2L, 2C, and 2R and the winning combination is clarified, and the gameability becomes easy for the player to understand.

  The rotation of the reels 2L, 2C and 2R is stopped within a maximum of 9 frames after the operation of the stop switches 8L, 8C and 8R is detected, and the symbols to be stopped are selected from the range of 5 symbols. Can do. Here, the symbols “BELL”, “REPLAY”, and “JAC” are always arranged at intervals of 4 symbols or less for each of the reels 2L, 2C, and 2R. Replay, JAC, and JACIN will not be missed when they are selected. In particular, the JAC in the regular bonus will be won with a very high probability of approximately 1 / 1.28, but since this can not be missed, the player will effectively hold on to the regular bonus. It becomes unnecessary, and it becomes possible to advance the game easily.

  As described above, the types of winning combinations that are subject to internal lottery for each gaming state are registered in the winning combination table by gaming state, but the number of judgment values that determine the winning probability of each combination is referred to from the determining table. Stored in the address. In the role table, the number of medals when a winning of each role occurs is also registered.

  In the role-specific table, the number of medals is registered according to the number of bets, and when a winning of cherry or bell occurs, the number of medals is set according to the number of bets (although the result is the same medal for cherry) Number is set). Here, the bet number in the regular bonus is fixed at 1, but the bet number in the gaming state other than the regular bonus is fixed at 3. As a result, an appropriate number of medals can be paid out according to the gaming state simply by acquiring the payout number according to the number of bets. Further, since it is not necessary to determine the gaming state when setting the number of medals, the processing steps in the winning determination process are simplified. In addition, the number of bets 1 corresponding to the regular bonus has a higher number of medals at the time of winning the bell than the number 3 of bets, so the player's expectation in the regular bonus is further enhanced, and the interest of the game is enhanced. Can be improved.

  For the cherries and bells defined as winning combinations in any gaming state in the role-specific table, the storage address of the determination value number is registered for each bet number, and the determination value number is determined according to the bet number. Will be acquired. Here, the bet number in the regular bonus is fixed at 1, but the bet number in the gaming state other than the regular bonus is fixed at 3. Thereby, the internal lottery of cherries and bells can be performed with the winning probability corresponding to the gaming state only by acquiring the number of determination values according to the number of bets. In addition, since it is not necessary to determine the gaming state when acquiring the determination value number, the processing steps in the internal lottery are simplified. In addition, the bet number 1 corresponding to the regular bonus has a higher probability of winning bells and cherries than when the bet number is 3, so the player's expectation in the regular bonus is further enhanced and the interest of the game is improved. Can be made.

  In addition, the storage address of the judgment value number of each combination registered in the combination table may differ depending on the set value, but the winning probability is the same regardless of the set value. For the winning combination, the number of determination values is stored in common regardless of the set value. By storing the number of determination values in common in this way, the storage capacity required for that is reduced. However, in the role-specific table, even if the target number of the internal lottery is the same as the set bet number and the address storing the number of judgment values referenced according to the set value is different, it is stored at a different address. In some cases, the number of determination values is the same.

  In general, in the development stage, the simulation is performed while adjusting the number of determination values according to the set values for at least some of the combinations (that is, adjusting the winning probability of internal lottery). As the initial number of determination values, a different number of determination values is registered according to the set value. However, as a result of adjustment by simulation, the number of determination values when the set values are different may be the same. Although the same number of judgment values was registered as the initial number of judgment values according to the set value, the number of judgment values registered from the beginning may be used as it is depending on the result of simulation (result of simulation). The number of judgment values different from the initial value, that is, the number of judgment values may differ depending on the set value). Then, the number of determination values obtained with an appropriate result in the simulation in each case is selected as the number of determination values to be set in the mass production model.

  Here, even if the number of determination values adjusted by the simulation is the same regardless of the set value, the number of determination values is stored in the ROM 41b with the same address assignment as that in the development stage. It can be used as a model for mass production. For this reason, it is not necessary to change the method for storing the number of judgment values in the model for mass production from the model for development, so that development from the initial design stage to the model for mass production can be easily performed. Become.

  Further, the storage address of the determination value number of each combination registered in the combination table is different depending on the number of bets (1 or 3). For example, the number of determination values stored at different addresses May be the same.

  In the development model, it is normal to perform simulation while finely adjusting the judgment value data according to the number of bets (the same as when the initial number of judgment values is different) There may be cases). Here, even if the number of decision values adjusted by the simulation becomes the same regardless of the number of bets, the number of decision values is stored in the ROM 41b with the same address assignment as the address assignment in the development stage. It can be used as a model for mass production. For this reason, it is not necessary to change the method for storing the number of judgment values in the model for mass production from the model for development, so that development from the initial design stage to the model for mass production can be easily performed. Become.

  In addition, the internal lottery adds the number of judgment values of each role referred from the role-specific table to the acquired random number for internal lottery, and depending on whether or not the result of the addition overflows, Judgment is made on whether or not there is a win. For this reason, an internal lottery can be performed using the number of determination values of each combination as it is. In addition, when generating the winning determination table before the actual winning determination is performed, the loop processing is required twice. However, according to this embodiment, the loop processing in the lottery processing may be performed only once. Thus, the processing efficiency in the entire lottery process is high.

  Further, in the internal lottery in the normal gaming state, the lottery for the small combination and re-playing combination and the lottery for the special combination are separately performed based on the same random number for internal lottery. Then, after the special combination is established, that is, in a state where the special combination winning flag is carried over, only the small combination and the re-playing combination are drawn. For this reason, a plurality of special roles will not be won in duplicate. In addition, since the lottery of the small role and the re-playing role can be shared before and after the special role is established, the internal lottery in the normal gaming state can be simplified, and in the state that is carried over after the special role is established. Since it is only necessary to perform the lottery of the small combination and the re-playing combination, the processing efficiency of the internal lottery in the state where the winning of the special combination is carried over becomes high.

  In the present embodiment, the lottery for the small role and replaying role and the lottery for the special role are separately performed based on the same random numbers for internal lottery. In the state where the winning flag is carried over, only the small role and the re-playing role are drawn, but even after the special role is established, If a special role is won by a special role lottery, the winning may be treated as invalid. Even in this case, multiple special roles may be won in duplicate. Absent.

  In addition, from the number of determination values stored in the address area registered in the role-specific table for the small role and the re-playing role and the number of determination values stored in the address area registered in the role-specific table for the special role It is possible to specify the range of judgment values for winning a small role, replaying role, and special role independently, and the range of judgment values for winning a small role and special role in duplicate. If the value obtained as a random number for internal lottery is included in the range of judgment values for each of the small role, replaying role, and special role specified by these judgment value numbers, It is determined that the re-playing role and the special role are each elected independently, and if both the small role and the special role are included in the range of judgment values to be won, both the small role and the special role are elected. It comes to judge. For this reason, if the value within the range in which the winning of both the special role and the small role is determined is obtained as a random number for internal lottery, the special role and the small role will be won at the same time. When the value of the range in which only the winning is determined is acquired as a random number for internal lottery, only the special combination or the small combination will be selected. As a result, even if a small role winning is generated as a result of the game, it is not denied that the occurrence of a special role with a higher advantage than the small role is allowed. A player's expectation can be maintained.

  In this embodiment, the number of judgment values stored in the address area registered in the role-specific table for the small role and the re-playing role and the address area registered in the role-specific table for the special role are stored. Based on the number of judgment values, it is possible to specify the range of judgment values for winning a small role, replaying role, and special role independently, and the range of judgment values for winning a small role and special role in duplicate. However, the number of judgment values stored in the address area registered in the role-specific table for the small role and the re-playing role and the judgment value stored in the address area registered in the role-specific table for the special role From the number, it may be possible to specify only the range of the judgment value that the re-playing role is won alone, and the range of the judgment value that the small role and the special role are won in duplicate. According to such a configuration, the game As a result of a small role winning as a result of Expected for that you have selected haves. In addition, from the number of determination values stored in the address area registered in the role-specific table for the small role and the re-playing role and the number of determination values stored in the address area registered in the role-specific table for the special role In addition, it may be possible to specify only the range of the judgment value that the re-playing role and the special role will be won alone, and the range of the judgment value that the small role and the special role will be won, and according to such a configuration, Even if the small role is not won as a result of the game, it is not denied that the special role is won, so the player's expectation for the special role can be maintained even in such a situation. In addition, from the number of determination values stored in the address area registered in the role-specific table for the small role and the re-playing role and the number of determination values stored in the address area registered in the role-specific table for the special role In addition, it may be possible to specify only a range of judgment values for winning a re-playing role and a small role alone, a range of judgment values for winning a small role and a special role, and according to such a configuration, Even if a small role wins as a result of the game, it is not denied that the special role has been won. Therefore, even in such a situation, the player's expectation for winning the special role can be maintained.

  In this embodiment, only the big bonuses (1) and (2) and the cherry are duplicated and can be won. For example, the big bonuses (1) and (2) and the cherry and the big bonuses (1) and (2) You may be able to win a bonus and multiple types of small roles such as bells. Further, in this case, the range of determination values for winning the big bonus (1) (2) and cherry is more than the range of determination values for winning the big bonus (1) (2) and bell. Is set to be larger so that the probability of winning Big Bonus (1) (2) and Cherry at the same time is higher than the probability of winning Big Bonus (1) (2) and Bell at the same time. In this way, the chance of winning a small bonus will be higher when Cherry wins than when Bell wins, because it is more likely to be won at the same time as Big Bonus (1) (2). When winning a prize, the expectation of winning the big bonus (1) and (2) can be changed depending on the type of the small role, so that interest can be enhanced.

  In the present embodiment, the random number for internal lottery acquired by the random number acquisition process is not used as it is from the random number generation circuit 42 by the sampling circuit 43 but is used after being processed by software. Yes. The random number generation circuit 42 generates a random number by updating at a high speed at the frequency of the pulse signal of the pulse generation circuit 42a. However, in the random number for internal lottery after processing by software, the periodicity of the update is increased by the processing. It will be lost.

  On the other hand, in the internal lottery, since the number of determination values corresponding to each combination is sequentially added to the random number value for internal lottery, each combination is determined as a winning combination as shown in FIGS. The random number value for the internal lottery to be set will be hardened. On the other hand, it is possible to prevent the player from aiming as much as possible by losing the periodicity of the random numbers for internal lottery by processing by software and varying the values.

  Moreover, the frequency of the pulse signal generated by the pulse generation circuit 42a for updating the values of the counters 42b and 42c of the random number generation circuit 42 is higher than the frequency of the operation clock of the CPU 41a, and is not an integral multiple. For this reason, it becomes difficult for the update of the random number generated by the random number generation circuit 42 to be synchronized with the process performed by the CPU 41a. In addition, by increasing the frequency of the pulse signal of the pulse generation circuit 42a, the update speed of the random number generated by the random number generation circuit 42 can be made extremely fast.

  On the other hand, the processing of the random number by software only needs to replace the upper byte and the lower byte of the random number extracted from the random number generation circuit 42 by the sampling circuit 43. Therefore, even a relatively large random number of 16 bits does not increase the load required for processing necessary to lose periodicity and can be easily acquired. Since a large random number can be acquired in this way, the probability setting in the internal lottery can be finely performed.

  Although the embodiments of the present invention have been described with reference to the drawings, the present invention is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. Needless to say.

  For example, in the above embodiment, when the rotation of the reel is started and when the reel is stopped and the reel that is still rotating still remains, the table index and the table creation data stored in the ROM 41b are referred to. Then, the stop control table is created for each spinning reel. However, the winning control status for each gaming state and the stop control table for each reel stop status are registered in the ROM 41b in advance. Based on the index, it is possible to specify the necessary stop control table according to the winning status of the role for each gaming state and the stop status of the reel, when the reel starts to rotate and when the reel stops, and still When the rotating reel remains, refer to the table index and stop control table for each rotating reel It may be set.

  Further, in the above embodiment, 42 areas (frames) divided every 4 steps (every 1/2 symbol) are defined for one reel, and each area (area number) is defined as a stop control table. Corresponding to the stop control table in which the number of frames to be drawn (stop position) is uniquely determined, that is, the stop control table in which the stop position is uniquely determined corresponding to an area less than the range in which one symbol fluctuates. The reel stop control is performed by using a stop control table in which the number of drawn symbols (stop position) is uniquely set for each symbol. By doing so, the capacity of the table creation data for creating the stop control table can be further reduced.

  In addition, the number of frames to be drawn (stop position) is uniquely determined corresponding to the area less than one symbol only in a specific area such as a stop operation position that satisfies the chance derivation condition. Further, the stop control of the reel may be performed using a stop control table in which the number of drawn symbols (stop position) is uniquely determined, and in this way, the stop position with respect to the stop operation position can be diversified. Furthermore, the capacity of the table creation data for creating the stop control table can be reduced.

  In addition, stop control in which the number of drawing steps and the number of drawing frames (stop position) are uniquely determined for each area subdivided from the 1/2 symbol, for example, one step, that is, every minimum unit when the reel motor is driven. Reel stop control may be performed using a table, and in this way, the stop position can be changed in units of steps of the reel motor, and the stop position relative to the stop operation position can be further diversified. it can.

  In addition, only for a specific area such as a stop operation position that satisfies the chance derivation condition, the number of steps to be drawn and the number of frames to be drawn (stop position) are uniquely determined corresponding to one step. The number of drawn symbols (stop position) is uniquely determined every time, or the reel stop control is performed using a stop control table in which the number of drawn frames is uniquely determined for each range of a plurality of consecutive steps. In this way, the stop position with respect to the stop operation position can be further diversified, and the capacity of the table creation data for creating the stop control table can be reduced.

  Hereinafter, a modified example of the reel control using the stop control table in which the stop position is determined in units of steps will be described with reference to FIGS. In the case of Big Bonus (1) + Loss, Big Bonus (2) + Loss, Regular Bonus (1) + Loss, BB (1) Loss, BB (2) Loss, RB shown in FIGS. The case where the stop control table of the loss item is applied as it is, and here, a case where no combination is won will be described.

  In this modified example, when no combination is won in the normal game state, and all reels are still rotating, the number of drawn frames in the area numbers 17, 19, 21, 23, 25, 27 A stop control table in which (stop position) is determined in units of steps is selected as a left reel stop control table. In this stop control table, the first step number in the area numbers 17, 19, 21, 23, 25, 27 (for example, 64 steps in the case of the area number 17) is the first area, the area number 17, The range of the number of steps from the second to the last in 19, 21, 23, 25, 27 (for example, 65 to 67 steps in the case of region number 17) is set as the second region of the region number, and region numbers 17, 19 , 21, 23, 25, and 27, the number of frames to be drawn (stop position) is determined for each of the first area and the second area.

  For the first area of area numbers 17, 19, and 21, the same number of drawn frames as the number of drawn frames determined for area numbers 17, 19, and 21 of the BB (1) loss item shown in FIG. The number of frames is determined, and for the first area of area numbers 23, 25, and 27, it is determined for area numbers 23, 25, and 27 of the BB (2) loss and RB loss items shown in FIG. The number of frames to be drawn is the same as the number of frames to be drawn. For the second areas having the area numbers 17, 19, 21, 23, 25, and 27, the area numbers 17, 19, and 21 of the loss item shown in FIG. , 23, 25, and 27, the same number of drawn frames is determined.

  In this modified example, when no combination is won in the normal gaming state and all the reels are rotating, the above-described area numbers 17, 19, 21, 23, For 25 and 27, a stop control table in which the number of frames to be drawn (stop position) is determined for each of the first area and the second area is selected, the left reel is stopped first, and area numbers 17, 19, and 21 are selected. , 23, 25, 27 when the left reel is stopped at the timing of the first area, that is, the number of steps from the reel reference position is 64, 72, 80, 88, 96, 104. As the stop control table, the stop control table corresponding to the items of BB (2) loss and RB loss shown in FIG. 12 is selected. When the middle reel is stopped and the “watermelon” symbol is tempered on the winning line L5, the stop control table on the left side corresponding to the item of the watermelon upward rising template shown in FIG. 13 is used as the stop control table for the right reel. When the “watermelon” symbol is selected on the winning line L1, the right stop control table corresponding to the item of the watermelon middle stage shown in FIG. 13 is selected as the right reel stop control table.

  That is, in this modified example, when no combination is won in the normal gaming state, the reels stop in the order of left, middle, and right, and the area numbers 17, 19, 21, 23, 25, 27 A chance chance is derived on the condition that the left reel is stopped at the timing of the first area, that is, the number of steps from the reel reference position is 64, 72, 80, 88, 96, 104. It becomes.

  As described above, in the above modified example, when the left reel is set to the first stop when no winning combination is won in the normal gaming state, the region numbers 17, 19, 21, 23, 25, 27 In one area, that is, in the area numbers 16 to 17, the left reel is stopped at a timing of 8 steps (the number of steps moved by one symbol) at an interval of 1 step. , Big Bonus (2) + Loss, Regular Bonus (1) + Loss Control The same number of frames as the stop control table applied in case of loss, and stop operation of the left reel at these timings As a result, even if none of the roles are won in the normal gaming state, the same number of draws is the same as when the bonus is won. Since the display result is to be derived, even if you usually do not win in any of the roles in the gaming state, it is possible to effectively increase the player's expectation for the bonus of winning. In addition, since the same display result is derived with the same number of drawn frames as when the bonus is won for only one step with respect to the number of steps moved by one symbol, the left is aimed at a specific symbol. Even when a reel stop operation is performed, the rate at which the same display result is derived with the same number of drawn frames as when the bonus is won will not be extremely high, Since the same display result may be derived with the same number of drawing frames as when the bonus is won in a wide range, the player's expectation for winning the bonus is more effectively increased be able to.

  Further, in the embodiment, among the plurality of stop control tables that uniquely determine the number of frames to be drawn with respect to the stop operation position, the winning status of each role in each gaming state, the reel stop status (and the stop operation that has been stopped) The stop control table uniquely determined for the position) is selected, and the reel stop control is performed according to the selected stop control table, but a plurality of stop positions uniquely determining the stop position with respect to the stop operation position The reel stop control may be performed using a specific table instead of the stop control table. Specifically, when a stop operation is detected, control is performed to stop the reel at a stop position uniquely specified corresponding to the stop operation position with reference to the stop position specifying table.

  Even in this case, when one of the bonuses is won in the normal gaming state and no other winning combination is won, the stop operation position that is a condition for deriving the chance eye (the constituent symbol of the chance eye is the stop position) The specified stop operation position) is set to be larger than the stop operation position that is a derivation condition for the chance eye in the stop position specification table that is uniquely selected when no combination is won in the normal gaming state. By selecting the stop position specification table, it is possible to increase the rate at which chances are derived when any bonus is won, so the player who wins the bonus as the chance is derived Can raise the sense of expectation.

  Further, by defining a stop priority for the stop position, a plurality of stop priority tables that uniquely determine the stop position with respect to the stop operation position (the number of steps from the reel reference position) are used instead of the stop control table. Reel stop control may be performed. Specifically, when a stop operation is detected, the stop priority table is referred to, the stop priorities of all stop positions within the retractable range (up to 10 frames) from the stop operation position are compared, and the highest stop priority. The reel is stopped at a high stop position.

  Even in this case, when one of the bonuses is won in the normal gaming state and the other combination is not won, the priority of the stop position, which is the derivation condition for the chance, is any priority in the normal gaming state. By selecting a stop priority table that is set higher than the priority of the stop position, which is the derivation condition of the chance in the stop priority table that is uniquely selected when no role is won, either bonus will be Since the rate at which chances are derived when winning is increased, the player's sense of expectation for winning the bonus can be increased as the chances are derived.

  Also, select the number of draws that is uniquely determined for the winning status of each role in each gaming state, the reel stop status (and the stop operation position of the stopped reel or the stop position of the stopped reel) However, if the target stop position is within the selected number of frames to be pulled when the stop operation is performed, pull-in control is performed to pull the stop position and stop, and the stop is prohibited. Alternatively, kick control (so-called control method control) may be performed in which another stop position is pulled in and stopped so as not to stop the stop position. Since the stop position is uniquely determined with respect to the stop operation position (number of steps from the reel reference position) by performing the pull-in control and the kick-off control in this way, the control for deriving the display result by the pull-in control and the kick-off control is It can be said that this is a control pattern for uniquely specifying the stop position with respect to the stop operation position.

  Even in this case, when any bonus is won in the normal game state and no other combination is won, the normal game state By selecting the number of drawn frames that is set more than when none of the roles are won in, you can increase the rate at which chances are derived when any bonus is won As the chances are derived, it is possible to increase the player's expectation for winning the bonus.

  In addition, the control pattern uniquely determined for the winning status of each role in each gaming state, the reel stop status (and the stop operation position of the stopped reel or the stop position of the stopped reel) is selected. If the reel stop control is performed according to the control pattern, the reel stop control by the stop control table, the reel stop control by the stop position specifying table, the reel stop control by the stop priority table, the pull-in control, and the kick-off control are performed. For example, only the reel that has stopped first is controlled by using the stop control table, and the other reels are controlled by pull-in control and kick-off control. The stop control may be performed.

  Further, in the above embodiment, a control pattern uniquely determined with respect to the winning status of each combination in each gaming state and the stop status of the reel (and the stop operation position of the stopped reel) is selected, Although the reel stop control is performed according to the control pattern, at least a control pattern uniquely determined for the winning situation of each role in each gaming state is selected, and the reel stop control is performed according to the selected control pattern. Anything you want to do.

  Further, in the above embodiment, in the normal gaming state, no role is won, that is, the winning situation is one role, but both the special role and the small role and re-playing role in the internal lottery. When the range of random values for internal lottery that causes a loss is multiple ranges, and the random number value for internal lottery is a value in each range, different types of loses are assigned, types of loses, and reel stop status A control pattern uniquely defined for (and a stop operation position of a stopped reel or a stop position of a stopped reel) may be selected, and stop control of the reel may be performed according to the control pattern. In this way, even when a random value for internal lottery that causes a loss is acquired, the display result derived by the difference in the range can be changed. In, it is possible to derive a display result of the reel in a more versatile manner even in the context of the same loss.

  Further, in the case of such a configuration, for example, in the case of a loss 2 in which two types of loss 1 and 2 are assigned to the loss in the normal gaming state and the range of random numbers is smaller than the loss 1 A control pattern that can be used to derive a chance is uniquely selected only when one of the bonuses is won and no other combination is won (bonus + losing). Well, by doing this, it is possible to increase the rate at which chances are derived when any bonus is won, so the player for winning the bonus as the chance is derived Can raise the sense of expectation.

  Further, in the above embodiment, when any bonus is won in the normal gaming state, the stop operation position is a condition from which a chance is derived compared to the case where no combination is won in the normal gaming state. By controlling the reels to stop according to the stop control table that defines a large number of points, when any bonus is won in the normal gaming state, it is higher than when no combination is won in the normal gaming state Opportunities are derived in proportion, but for example, when you win a big bonus, you reach a certain reach (when you win a bonus) than when you win a regular bonus The reels are stopped according to a stop control table in which many stop operation positions that are the conditions under which the display results derived under the conditions are derived. In this way, when a big bonus is won, a specific reach is derived at a higher rate than when a regular bonus is won. By deriving a specific reach, it is possible to increase the player's expectation for winning a big bonus that can be expected to win more medals than a regular bonus.

  In addition, when a bonus is won in a normal gaming state and a specific small role is won, a specific small role is more effective than when only a specific small role is won in a normal gaming state. In the normal gaming state, one of the bonuses is won, and a specific bonus is won by performing a control to stop the reels according to a stop control table in which a large number of stop operation positions that are conditions to be derived to a specific winning line are determined. When winning a small role, a specific small role may be led to a specific winning line at a higher rate than when only a specific small role is won in the normal gaming state. By doing so, if you win one of the bonuses and you win a specific small role, the specific small role will be at a higher rate than if only a specific small role is won. specific Will be led to the prize line, it is possible to increase the player's expectation for the bonus of winning by a particular small role is derived in specific winning line.

  Moreover, in the said Example, the determination value number storage area | region of RAM41c in which the determination value number used for an internal lottery is memorize | stored shall memorize | store the determination value number in each case using a 2 byte area | region. However, in a general slot machine, the number of judgment values for special roles is not often set to exceed 255 in any gaming situation. As described above, for those that do not need to set the number of determination values exceeding 255, the number of determination values may be stored using only a 1-byte area.

  Further, in the above-described embodiment, some of the determination values that are common regardless of the set value are stored in common for all of the set values 1 to 6, but the number of determination values is related to the set value. Even common items can be individually stored for each of the setting values 1 to 6. Further, if the number of determination values is common regardless of the set value, all of them can be stored in common for all of the set values 1 to 6.

  Moreover, in the said Example, it was whether it memorize | stored in common with the whole setting value 1-6, or it memorize | stored separately with respect to each of the setting values 1-6 in the said Example. However, it is assumed that the number of determination values is not stored in common for all of the setting values 1 to 6 (the common flag for the setting value is not set). About 4-6, the number of judgment values can also be made common. The same applies to the number of determination values for the bet number. For example, the bet numbers 1 and 2 may be common and the bet number 3 may be individual.

  In the above-described embodiment, the number of determination values referred to according to the number of bets for the same combination at the same set value is stored at a different address for each of the bets (1 or 3). That is, for the same combination at the same set value, even if the number of judgment values referred to according to the number of bets is the same, it is stored separately, but the combination with the same winning probability regardless of the number of bets For the role that makes the determination value number storage address common, or for the role that makes the winning probability the same regardless of the setting value and the number of bets, the address of the determination value number storage address is made common In this way, by storing the number of determination values in common, it is possible to reduce the storage capacity required for that purpose.

  In the embodiment, the number of determination values acquired according to the set value or the like is sequentially added to the random number value for internal lottery. Subtraction may be performed sequentially, and the result of the subtraction may be used as a new random value for internal lottery. When the number of determination values is subtracted from the random number value for internal lottery, it can be determined whether or not an overflow has occurred in the subtraction result (here, the subtraction result becomes negative).

  In the embodiment, in the internal lottery, the number of determination values of each combination according to the game situation is sequentially added to the acquired random number for internal lottery, and when the addition result overflows, the winning combination is won. It was supposed to be judged. On the other hand, a winning determination table in which a determination value for determining each combination as winning is determined for each game in accordance with the number of determination values for each combination according to the game situation, and the internal random number for internal lottery acquired It is good also as what performs an internal lottery by comparing this value with the determination value of each combination. In addition, a winning determination table in which determination values for determining each winning combination are stored in advance in the ROM 41b, and an internal lottery value is compared by comparing the acquired internal random number value with the determination value for each winning combination. It is good also as what performs.

  Further, in the above embodiment, the game can be started only by setting 3 as the bet number in the small role game in the normal gaming state and the big bonus. On the other hand, even in the small game in the normal gaming state and the big bonus, it is possible to start the game by setting 1 as the bet number, and further, by setting 2 as the bet number, You may be able to get started. As a result, when 1 or 2 is set as the bet number in the small game in the normal gaming state and the big bonus, the winning probability of the small role in the internal lottery is lower than when 3 is set as the bet number. In both cases, the number of medals to be paid out when winning a small role can be increased. For example, when 3 is set as the bet number in the small game in the normal gaming state and the big bonus, the winning probability of the bell is 1 / 4.82 and the payout number is 7, but the bet number is 1 or 2 Is set, the winning probability of the bell may be set lower than 1 / 4.82 and the payout number may be increased more than 7. Further, the winning probability of the bell and the number of payouts may be changed when 1 is set as the bet number and when 2 is set.

  In the embodiment, in the internal lottery in the normal gaming state, for the same random number for internal lottery, the lottery of the small role and the replaying role referring to the role-specific table for the small role and the replaying role, and the special role The special role lottery that refers to the role-specific table is separately performed, and the number of judgment values stored in the address area registered in the role-specific table for the small role and the replay role and the special role Based on the number of judgment values stored in the address area registered in the role-specific table, the range of judgment values that each small role, replaying role, and special role win independently, and the small role and special role are won in duplicate. The range of judgment values to be specified can be specified, so that special roles and small roles can be won at the same time, but in the role table, the storage address of the number of judgment values corresponding only to special roles , Both special and small roles In the internal lottery, the storage address of the corresponding determination value number, the storage address of the determination value number corresponding only to the small role, and the storage address of the determination value number corresponding only to the replaying role are registered respectively. If the number of judgment values for each role referenced from the role table is added to the acquired random number for internal lottery, and the result of addition with the number of judgment values corresponding to only the special role overflows, the special role If the result of addition with the number of judgment values corresponding to both the special role and the small role overflows, the winning of both the special role and the small role is determined, and the small role or replay role If the result of addition with the number of decision values corresponding to only overflows, the winning combination of only the small role or replaying role is judged, so that the special role and the small role can be won simultaneously. You can also. In other words, it is possible to specify a range of judgment values for winning a small role, a replaying role, and a special role separately from a single role-specific table, and a range of judgment values for winning a small role and a special role in duplicate. By doing so, it is possible to adopt a configuration in which a special role and a small role can be won simultaneously.

  FIG. 32 is a diagram showing a modified example of the role-specific table, and FIG. 33 is a flowchart showing a modified example of the internal lottery process.

  The role-specific table shown in FIG. 32 includes big bonus (1), big bonus (2), regular bonus (1), regular bonus (2), JACIN, JAC, big bonus (1) + cherry, big bonus (2 ) + Cherry, Cherry, Bell, Replay are stored in the order in which the storage addresses of the judgment value number are referred to.

  The number of determination values for each combination is registered corresponding to the number of bets (BET) set by the player in the game. This is because even with the same combination, the winning probability in the regular bonus may differ from other combinations. In addition, the number of determination values according to the number of bets for each combination may be common regardless of the set value, or may be different depending on the set value. If the number of determination values is common regardless of the set value, a common flag is set (value is set to “1”).

  Big Bonus (1), Big Bonus (2), Regular Bonus (1), Big Bonus (1) + Cherry, Big Bonus (2) + Cherry are roles that are subject to internal lottery only in the normal gaming state, A storage address of the number of determination values corresponding to the bet number 3 in the normal gaming state is registered. Among these combinations, the value of the common flag is 0 for the big bonus (1), the big bonus (2), and the regular bonus (1), and the storage address of the number of determination values is individually set according to the set value. Is registered. Further, for big bonus (1) + cherry and big bonus (2) + cherry, the value of the common flag is 1, and the storage address of the common determination value number is registered regardless of the set value. Regular bonus (2) and JACIN are internal lottery targets only in the small bonus game in the big bonus, and the storage address of the number of judgment values corresponding to the bet number 3 in the small bonus game is registered. . The value of the common flag for this combination is 1, and a common storage address for the number of determination values is registered regardless of the set value.

  The JAC is a role that is subject to internal lottery only with the regular bonus, and the storage address of the number of determination values corresponding to the bet number 1 with the regular bonus is registered. The common flag of this combination is 0, and the storage address of the common determination value number is registered regardless of the set value corresponding to each bet number. Replay is a role that is subject to internal lottery only in the normal gaming state, and a storage address for the number of determination values corresponding to the bet number 3 in the normal gaming state is registered. The common flag for this combination is 1, and a common storage address for the number of determination values is registered regardless of the set value.

  Cherry and bell are the targets that are subject to internal lottery in any gaming state, the storage address of the judgment value number corresponding to the number 1 bet in the regular bonus, and the number 3 bets in the normal gaming state or small role game And the storage address of the number of judgment values corresponding to. For cherry, the common flag is 1, and the storage address of the common number of determination values is registered corresponding to the number of bets regardless of the set value. For the bell, the common flag is 0, and the storage address of the number of determination values is individually registered according to the set value corresponding to each bet number.

  Next, based on the flowchart shown in FIG. 33, the modification of the internal lottery process which CPU41a performs is demonstrated.

  In this internal lottery process, a random number acquisition process is performed (Sg101). In this random number acquisition process, a random number value for internal lottery is acquired based on the random number generated by the random number generation circuit 42.

  Then, the setting value stored in the RAM setting value work is read (Sg102), and whether or not the read setting value is in the range of 1 to 6, that is, whether the setting value stored in the setting value work is an appropriate value. If the read set value is not a value in the range of 1 to 6, an error code indicating a RAM abnormality is set in the RAM 41c (Sg104), and the process proceeds to the error process shown in FIG.

  If the set value read in the step of Sg103 is in the range of 1 to 6, the combinations registered in the combination table of FIG. 32 corresponding to the current gaming state are sequentially read (Sg105). Whether the type of the role read here is a regular bonus (regular bonus (1), regular bonus (2)), big bonus (big bonus (1), big bonus (2) (+ not including cherry)) Is determined (Sg106). If it is one of the regular bonus, big bonus, or JACIN, is the regular bonus or big bonus winning flag already set in the RAM 41c in the previous game, and whether it has been carried over without winning based on the winning flag? It is determined whether or not (Sg107). If the type of the read combination is neither a regular bonus nor a big bonus, the process proceeds to Sg108.

  If the winning flag for the regular bonus or the big bonus has already been set, the process returns to the processing of Sg105, and further, the next role registered in the winning combination table according to the gaming state is read (regular bonus, big bonus and JACIN Is registered first in the role table, and this does not end the lottery process). Even if the type of the read combination is regular bonus, big bonus or JACIN, if neither the regular bonus winning flag nor the big bonus winning flag is set, the process proceeds to Sg108.

  In Sg108, the BET number set in the step Sd1 is further read, and the common flag setting status is acquired from the role-specific table of FIG. 32 for the role and the role corresponding to the read BET number. As a result, it is determined whether a common flag is set for the combination and the BET number (Sg109).

  If the common flag is set, the number of determination values stored in the address registered in the role-specific table of FIG. 32 for the role and the BET number is acquired (Sg110). Then, the process proceeds to Sg112. If the common flag is not set, the setting value set in the RAM 41c is read, and the determination stored in the address registered in the role-specific table corresponding to the setting value read for the role and the BET number The number of values is acquired (Sg111). Then, the process proceeds to Sg112.

  In the step of Sg112, the number of determination values acquired in the step of Sg110 or Sg111 is added to the random number value for internal lottery, and the result of the addition is used as a new random number value for internal lottery. Here, it is determined whether or not an overflow has occurred when the number of determination values is added to the value of the random number for internal lottery (Sg113). If an overflow occurs, it is determined whether or not the winning combination is big bonus (1) + cherry, big bonus (2) + cherry (Sg114). If the winning combination is not the big bonus (1) + cherry and the big bonus (2) + cherry, the winning flag of the winning combination is set in the RAM 41c (Sg114). Then, the internal lottery process is terminated, and the process returns to the flowchart of FIG.

  In the step of Sg114, if the combination is big bonus (1) + cherry, big bonus (2) + cherry, the regular bonus or big bonus winning flag is already set in the RAM 41c in the previous game, and the winning flag It is determined whether it is carried over without winning based on (Sg116). If neither the regular bonus winning flag nor the big bonus winning flag is set, the corresponding winning flags of the big bonuses (1) and (2) and the winning flag of the cherry winning flag are respectively set in the RAM 41c (Sg117). Then, the internal lottery process is terminated, and the process returns to the flowchart of FIG.

  If the winning flag for the regular bonus or the big bonus has already been set in the step of Sg116, the winning flag for cherry is set in the RAM 41c (Sg118). Then, the internal lottery process is terminated, and the process returns to the flowchart of FIG.

  If no overflow has occurred in the step of Sg113, it is determined whether there is a combination that has not yet been processed among the combinations determined for the gaming state (Sg119). If there is a combination that has not yet been processed, the process returns to Sg105, and the process continues with the next combination registered in the winning combination table according to gaming state as the processing target. If there is no combination not to be processed, the internal lottery process is terminated and the process returns to the flowchart of FIG.

  As described above, according to the modification applied with the role-specific table shown in FIG. 32 and the internal lottery process shown in FIG. 33, the value of the range in which the winning of both the special role and the small role is determined is the internal lottery value. If it is acquired as a random number, the special role and the small role will be elected at the same time, and if the value of the range where only the special role is determined is acquired as a random number for internal lottery, only the special role Will be elected. As a result, even if a small role winning is generated as a result of the game, it is not denied that the occurrence of a special role with a higher advantage than the small role is allowed. A player's expectation can be maintained. In addition, since it is not necessary to register the number of judgment values corresponding to the special role lose, it is possible to save the capacity of the ROM 41b and to share the internal lottery process regardless of the gaming state, thereby simplifying the program. it can.

  Note that, in the above configuration, the range of determination values that each of the small combination, replay combination, and special combination wins independently from the number of determination values stored in the address area registered in the combination table shown in FIG. And a range of judgment values for winning a combination of small and special roles, but it is possible to replay from the number of judgment values stored in the address area registered in the role-specific table. It may be possible to specify only a range of judgment values for winning a combination, and a range of judgment values for winning a combination of small roles and special roles. If you win a prize, you can expect to be elected for a special role. Also, from the number of judgment values stored in the address area registered in the role-specific table, the range of judgment values that the re-playing part and special part win independently, the judgment value that the small part and special part wins redundantly However, according to such a configuration, even if a small role is not won as a result of the game, it is not denied that a special role is won. Even in the situation, the player's expectation for winning the special role can be maintained. In addition, from the number of judgment values stored in the address area registered in the role-specific table, the range of judgment values that the re-playing part and small part wins alone, the judgment value that the small part and special part wins in duplicate However, according to such a configuration, even if a small role wins as a result of the game, it is not denied that a special role is won. Can maintain the player's expectation of winning special roles.

  In the above configuration, after the special role is established, that is, in the state where the special role winning flag is carried over, the value of the determination value range in which the special role is won alone is acquired as a random number for internal lottery. If the value of the range of judgment values for winning a combination of small roles and special roles is acquired as a random number for internal lottery, it is determined that only the small role is won, Even if multiple special roles are not won, it will be lost even when the value of the judgment value range in which small and special roles are won in duplicate is acquired as a random number for internal lottery. Even in this case, a plurality of special roles will not be won in duplicate. In addition, after the special role is established, the role-specific table in which data that can specify the range of the judgment value that the special role wins alone and the judgment value range that the small role and the special role wins are not registered, In other words, the internal lottery process may be performed by the role-specific table in which only data that can specify the range of the determination value that the re-game player wins and data that can specify the range of the determination value that the small role wins are registered. Well, even in this case, multiple special roles will never win.

  In the above embodiment, the entire high-order byte of the random number extracted from the random number generation circuit 42 is replaced with the low-order byte, and the entire low-order byte is replaced with the high-order byte. On the other hand, data of a specific bit out of random number bits extracted from the random number generation circuit 42 may be replaced with data of other bits. Alternatively, the random number value extracted from the random number generation circuit 42 may be directly acquired as a random number for internal lottery. Further, it may be processed into a random number for internal lottery by a method different from the above embodiment.

  FIG. 34 is an explanatory diagram of a first modification of the process until the CPU 41a processes the random number extracted from the random number generation circuit 42 into a random number for internal lottery by software. Also in the first modification, the random number extracted from the random number generation circuit 42 is stored in the 16-bit general-purpose register 41GR included in the CPU 41a.

  When the random number extracted from the random number generation circuit 42 is stored in the general-purpose register 41GR, the CPU 41a further extracts the value of the internal refresh register 41R as a processing random number. The CPU 41a adds the processing random number extracted from the refresh register 41R to the value of the upper byte of the general-purpose register 41GR (the value extracted from the upper counter 42c). The value of the lower byte of the general register 41GR (the value extracted from the lower counter 42b) is left as it is. Then, the CPU 41a obtains the value stored in the general-purpose register 41GR at this time as a random number for internal lottery, and sequentially adds the number of determination values thereto.

  FIG. 35 is an explanatory diagram of a second modification of the process until the CPU 41a processes the random number extracted from the random number generation circuit 42 into a random number for internal lottery by software. Also in this example, the random number extracted from the random number generation circuit 42 is stored in the 16-bit general-purpose register 41GR included in the CPU 41a.

  When the random number extracted from the random number generation circuit 42 is stored in the general-purpose register 41GR, the CPU 41a further extracts the value of the internal refresh register 41R as a processing random number. The CPU 41a adds the processing random number extracted from the refresh register 41R to the value of the upper byte of the general-purpose register 41GR (the value extracted from the upper counter 42c). The processing random number extracted from the refresh register 41R is also added to the lower byte value (the value extracted from the lower counter 42b) of the general-purpose register 41GR. Then, the CPU 41a obtains the value stored in the general-purpose register 41GR at this time as a random number for internal lottery, and sequentially adds the number of determination values thereto.

  In the first and second modified examples described above, the value of the refresh register 41R is extracted as a random number for processing, and this is extracted from the high-order byte of the random number extracted from the random number generation circuit 42 (in the second modified example, further lower byte) ) To process random numbers. The random number processing applied here includes at least processing for adding a processing random number to the upper byte. Thereby, the variation of the random numbers for internal lottery can be increased, and the player can prevent the aiming as much as possible.

  Further, since the processing random numbers are extracted from the refresh register 41R, no special configuration is required as means for generating the processing random numbers. Moreover, the value of the refresh register 41R is updated every time the CPU 41a fetches an instruction, and the update interval is not constant. Therefore, a random number with high randomness can be extracted as a processing random number. And since the randomness of the processing random number is high, the randomness of the random number for internal lottery generated using the random number is also high.

  In the first and second modifications, the value extracted from the refresh register 41R is added to the upper byte (and the lower byte) of the random number extracted from the random number generation circuit 42. A value that is periodically updated by hardware or software may be added. Further, instead of adding a value extracted from the refresh register 41R (or a value replacing the refresh register 41R), a logical operation such as subtraction, logical sum, or logical product may be performed.

  Further, bit replacement such as replacement of the upper byte and the lower byte shown in the above embodiment may be used in combination with the first and second modifications. Also in the first and second modified examples, the interrupt to the CPU 41a is prevented in order to prevent the contents of the general-purpose register 41GR from being rewritten between the extraction of the random number from the random number generation circuit 42 and the end of the processing. It will be prohibited.

  Further, in the second modification, processing random numbers to be added to the upper and lower bytes of the random number extracted from the random number generation circuit 42 may be separately extracted from the refresh register 41R at different timings. Separately prepare the processing random number to be added to the upper byte and the processing random number to be updated to the lower byte. Means for extracting may be provided. In this case, one of the means for updating the processing random number for the upper byte and the means for updating the processing random number for the lower byte can be constituted by the refresh register 41R.

  In the above embodiment, the case where the present invention is applied to the case where the random number generated by the random number generation circuit 42, that is, the random number extracted by the hardware random number function is processed by software has been described. However, the random number processing by the software described above may be applied to random numbers that are periodically updated by software. For example, the CPU 41a sends an instruction to the second microcomputer to extract a random number periodically updated by a timer interrupt or the like in a second microcomputer different from the microcomputer constituting the main control unit 41, and I The data can be input to the CPU 41a via the / O port 41d and stored in the general-purpose register 41GR. The function of the second microcomputer may be included in the microcomputer that constitutes the main control unit 41. Also in this case, the random number value obtained after processing can be varied, and the effect of preventing the player from aiming can be achieved.

  In the embodiment, the RAM parity adjustment data is stored so that the RAM parity of the RAM 41c becomes 0 in the power interruption processing, and it is determined whether or not the RAM parity of the RAM 41c is 0 at the time of restoration. Although it is determined whether or not the data in the RAM 41c is normal, of course, the RAM parity adjustment data is stored so that the RAM parity of the RAM 41c becomes 1 in the power interruption processing, and the RAM parity of the RAM 41c becomes 1 at the time of restoration. Whether or not the data in the RAM 41c is normal may be determined. Further, the checksum (exclusive OR of the data stored in the corresponding area) of all areas of the RAM 41c is calculated in the power interruption processing, and is stored in a specific area, and at the time of recovery, the RAM 41c is restored. The checksum of all the areas including the specific area where the checksum is stored is calculated. If the result is 00 (H), it is determined that the data in the RAM 41c is normal, and must be 00 (H). For example, it may be determined that the data in the RAM 41c is abnormal.

  If the checksum is stored normally in the power interruption processing, the checksum of the area excluding the specific area and the data stored in the specific area (the checksum calculated at the time of power interruption) ) Should take the same value, and if the checksum of the area excluding the specific area matches the data stored in the specific area, the result of calculating the exclusive OR of both data is Since the result of calculating the checksum of all areas including the specific area where the checksum of the RAM 41c is stored is 00 (H), it is determined that the data in the RAM 41c is normal. This is because it can.

  In this case as well, in the power interruption interrupt processing, before the checksum is calculated, the destructive diagnosis data (for example, 5A (H)) in which any bit becomes 1 is stored at a predetermined address and restored In addition to determining whether or not the checksum is 00 (H), it is also determined whether or not the data for destructive diagnosis is normally stored. The checksum is 00 (H) and the destructive diagnosis is performed. It is preferable to determine that the data in the RAM 41c is normal on the condition that the business data is also normal. Even if the data in the RAM 41c is not normal, if 00 (H) is stored in all areas, it will be determined to be normal by the checksum determination at the time of startup, After storing the destructive diagnostic data with the bit set to 1, calculate the checksum and store it in a specific area, and also check the destructive diagnostic data in addition to checking the checksum at startup, For example, even if all areas are cleared to 0 at startup, and the checksum is 00 (H) and determined to be normal, the destruction diagnosis data does not match the value stored at the time of power failure, Since the determination is made, it is possible to improve the accuracy of determining the abnormality of the data stored in the RAM 41c.

  In the above, the RAM parity or checksum of the RAM 41c is calculated in the power interruption processing and stored in the RAM 41c, and whether or not the RAM parity calculated based on all areas of the RAM 41c at the time of restoration is 0. Or whether the data in the RAM 41c is normal based on whether or not the checksum calculated based on all the areas of the RAM 41c is 00 (H). RAM parity or checksum of the RAM 41c is calculated and stored in a specific area, and the RAM parity or checksum excluding the specific area of the RAM 41c at the time of recovery is calculated, and the RAM parity or checksum stored in the specific area is calculated. The data in the RAM 41c depends on whether the comparison result matches It may be determined whether normal or not. In this case as well, as described above, before the RAM parity or checksum is calculated, the destructive diagnosis data in which any bit is 1 is stored at a predetermined address. In addition to determining whether or not the sums match, it is determined whether or not the data for destructive diagnosis is stored normally, the RAM parity and checksum match, and the destructive diagnostic data is also normal. It is preferable to determine that the data in the RAM 41c is normal under the above conditions.

  In the above-described embodiment, 5A (H) is stored in the RAM 41c as the failure diagnosis data in the power interruption processing. However, any data other than 0 may be stored and can be confirmed at the time of startup.

  In the above embodiment, when the CPU 41a is started, the RAM parity of the RAM 41c is calculated, it is determined whether or not the result is 0, and the destructive diagnosis data is normal on the condition that the RAM parity is 0. However, first, it is determined whether or not the data for destructive diagnosis is stored normally, and on condition that the data for destructive diagnosis is stored normally. The RAM parity of the RAM 41c may be calculated and it may be determined whether or not the result is 0. In this way, if the destructive diagnosis data is not normally stored, the RAM parity is calculated. Without calculation, it can be determined that the data in the RAM 41c is abnormal.

  In the embodiment, the main control unit 41 is activated based on a reset signal from a reset circuit 49 provided separately from the main control unit 41. The microcomputer which comprises may be mounted.

  In the above-described embodiment, the RAM 41c is mounted on the microcomputer constituting the main control unit 41. However, a RAM used as a work of the microcomputer may be mounted outside the microcomputer.

  In the embodiment, the power interruption detection circuit 48 monitors the DC voltage used in the slot machine 1 and detects the power interruption when the DC voltage becomes a certain voltage or lower. You may make it detect a power interruption, when the period when the said DC voltage became below a fixed voltage continued for a fixed period. Alternatively, the AC voltage supplied to the slot machine 1 may be monitored to detect a power interruption when a disturbance in the waveform of the AC voltage is detected or when the period continues for a certain period.

  In the above embodiment, the power interruption detection circuit 48 is mounted on the game control board 40. However, the power interruption detection circuit 48 may be mounted in other places. For example, the game control board 40 may be connected to the power supply board 100 or the power supply board 100. It may be mounted on a relay board or the like through which a power supply line is connected.

  In the embodiment, the slot machine for setting bets using medals and credits is used. However, the present invention is not limited to this, and the slot machine for setting bets using game balls. Alternatively, it may be a complete credit type slot machine that uses only credits to set the number of bets.

  Furthermore, as shown in FIG. 36, in addition to the medal insertion mechanism such as the flow path switching solenoid 30 and the insertion medal sensor 31, a ball capturing device 30 ′ and a ball capturing device 30 ′ for capturing game balls are used. In addition to a medal payout mechanism such as a hopper motor 34 and a payout sensor 35, a ball payout device 34 ′ for paying out a game ball, a ball payout, and the like are provided. A payout ball detection switch 35 ′ for detecting a game ball paid out by the device 34 ′ is provided, and it is possible to play a game by setting the number of bets using both medals and game balls, and generating a prize. The present invention may be applied to a slot machine from which medals and game balls are paid out.

With
The derivation control means includes
In a situation where a display result has already been derived in any one of the plurality of variable display areas and a display result has not yet been derived in another variable display area, a display result has not yet been derived. for unresolved variable display area, unresolved operation timing (1/2 symbols are timing deriving operating means is operated corresponding to the unresolved variable display area among the plurality of the predetermined timing for one cycle The predetermined number is determined from a plurality of control patterns (reel stop control by a stop control table) that uniquely specify a display result (stop position) derived with respect to a region number assigned for each step number of minutes). Determination result of means (result of internal lottery) and the already derived variable table of the plurality of timings in the already derived variable display area where the display result has already been derived Control pattern selection means for uniquely selecting a control pattern corresponding to an already derived operation timing (stop operation position) that is a timing at which the derivation operation means corresponding to the indicated area is operated (when any one reel stops) Including a process of selecting a data creation table corresponding to another reel and creating a stop control table corresponding to the reel that is changing from the selected data creation table),
