Abstract

<P>PROBLEM TO BE SOLVED: To realize stop control of variably displaying which suppresses a loss of a player in a slot machine having a special game state where a maximum delay time from the instruction of stopping of variably displaying of identification information to actual stop is controlled to be shorter than that in a normal game state. <P>SOLUTION: Fifteen tokens are put out by stopping with "cherry" at the upper stage or the lower stage of a left reel, and eight tokens are put out by stopping with "bell"s on an effective line. In CT (challenge time), the maximum stoppage delay time of a right reel is shortened from 190 ms to 75 ms to change normal 4-frame pulling-in to 1-frame pulling-in. For example, in the case of stopping the left reel as a third reel, "bell" is made into TENPAI (a state of requiring only one required pattern for finish) to the utmost extent in the range of the maximum stoppage delay time of each about a middle reel and the right reel. However, when leading out of a display result which cannot be led out in CT becomes inevitable by making "bell" into TEMPAI, if "cherry" can be stopped at the upper stage or the lower stage of the left reel in the range of 4-frame pulling-in, "bell" is not made into TEMPAI. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention provides a slot machine having a special gaming state in which the maximum delay time from the instruction to stop the variation display of the identification information to the actual suspension is controlled to be shorter than the normal gaming state, so that the variation display is stopped in the special gaming state. Regarding control.

  A slot machine generally includes a variable display device having a plurality of (usually three) reels having a plurality of types of symbols as identification information drawn on the outer periphery, and each reel has a start lever by a player. Rotation is started by operating, and when the player operates a stop button provided corresponding to each reel, the rotation is stopped within a range of a predetermined maximum delay time from the operation timing. . Then, a prize is generated according to the display mode derived when the rotation of all the reels is stopped.

  In order for a winning of each combination determined for each slot machine to occur, generally, a winning flag must be set by winning an internal lottery performed in advance (usually when the start lever is operated). . However, some slot machines reduce the maximum delay time from stop button operation timing to stop for at least one reel in each game, but if the stop button operation timing is appropriate, it is possible to win a small role Some have a gaming state called CT (Challenge Time).

  As a concrete example of CT, there is one that stops the reel stop control according to the random number value for a predetermined number of times when a specific condition is achieved (for example, see Patent Document 1). . In addition, the first reel that is stopped first among the three reels constituting the variable display device is subjected to the same stop control as that in the normal gaming state, but the second and third reels have the maximum delay time until the stop. Some have performed stop control to be shortened (see Non-Patent Document 1, for example).

  By the way, in the slot machine, it is usual that a plurality of types of small roles that are determined as only a medal payout are prepared with different medal payout numbers due to winning. If the timing of operating the stop button is appropriate in the CT gaming state, you can always win a small role if you can win a small role with a larger number of payouts than a small role with fewer payouts. However, a big profit can be obtained for the player.

  However, for example, even if there is still a possibility of winning a small role with a large number of payouts before the third reel stops, the stop button is operated to stop the third reel so as to win this It is not always possible. At this time, if there is no possibility of winning a small combination with a small number of payouts before the second reel stops, a small combination with a large number of payouts when the third reel stops is dropped. As a result, even a small role with a small number of payouts cannot be won. In this case, the CT is supposed to be in a gaming state that is advantageous to the player, and the player loses as much as the bet number set in the game.

  On the other hand, in the slot machine of Patent Document 1, only the stop control of the reel according to the random number value is considered, and such a loss of the player is not considered at all. It was. On the other hand, in the slot machine of Non-Patent Document 1, the maximum delay time of the stop control of the second and third reels is shortened to a state in which there is no drawing at all, especially according to the operation order of the stop buttons. Until the third reel was stopped, the idea of continuing to win the possibility of winning a small role with a small number of payouts as much as possible did not arise.

  In the slot machine having a special gaming state in which the maximum delay time from the instruction to stop the fluctuation display of the identification information to the actual suspension is controlled to be shorter than the normal gaming state, the present invention stops the fluctuation display that suppresses the loss of the player. The purpose is to realize control.

In order to achieve the above object, a slot machine according to the first aspect of the present invention includes:
By setting a predetermined number of bets for one game, the game can be started, and a plurality of variable display units (reels 3L, 3C, 3R) that display a plurality of types of identification information that can be distinguished from each other are variably displayed. In a slot machine in which one game is completed when a display result is derived to a variable display device (variable display device 2) including), and a winning can be generated according to the display result derived to the variable display device.
Derivation permitting means for allowing a predetermined lottery to be performed before the display result of the variable display device is derived and allowing a winning display result to be derived as a display result of the variable display device according to the result of the predetermined lottery. (Step S3, Steps S505 to S523),
Fluctuating display control means (step S4) for fluctuating and displaying identification information in each of the plurality of variable display portions;
Stop operation means (stop buttons 12L, 12C, 12R) for instructing to stop the variable display of the identification information on the plurality of variable display sections by the player's operation,
Stop operation detection means (stop switches 42L, 42C, 42R) for detecting the operation of the stop operation means corresponding to each of the plurality of variable display sections;
When the stop operation detecting means detects the operation of the stop operation means for each of the plurality of variable display portions, a predetermined maximum delay time (190 milliseconds (right reel 3R during CT) from the detection of the operation is detected. Is a variable stop control means (step S5, steps S701 to S711) for stopping the variable display of the identification information in the variable display unit corresponding to the detection of the operation within the range of 75 milliseconds)),
When a predetermined transition condition is satisfied, the maximum delay time from the detection of the operation of the stop operation means to the stop of the variation display of the identification information in the special variable display unit among the plurality of variable display units is set in the normal gaming state. Special gaming state control means for shifting the gaming state to a special gaming state (CT) that is shortened to a second maximum delay time (75 milliseconds) shorter than the first maximum delay time (190 milliseconds);
In the game controlled to the special gaming state, the derivation permitting means includes a first small combination display result (bell) accompanied by at least a first predetermined number of valuable values and a second larger than the first predetermined number. Allowing a second small role display result (cherry) with a predetermined number of valuable values to be derived as a display result of the variable display device;
The variable stop control means is defined for a variable display unit corresponding to the detection of the operation when the stop operation detection means detects an operation of the stop operation means while being controlled to the special gaming state. Performing control to preferentially derive identification information capable of deriving the second small role display result within the range of the maximum delay time,
When the identification information that can derive the second small combination display result cannot be derived within the range of the maximum delay time determined for the variable display section, the identification information that can derive the first small combination display result is derived. To stop the variable display in the variable display section,
When the display mode is such that the second small role display result can be derived even if the identification information that can derive the first small role display result is derived to the variable display portion, the first small role display result is displayed. It is characterized in that identification information capable of both derivation and derivation of the second small combination display result is derived and the variable display on the variable display unit is stopped.

  In the slot machine according to the first aspect, in the special gaming state, the maximum delay time in the special variable display unit is shortened, but at least the first small role display result and the second small role display result are always allowed to be derived. Has been. Here, although it becomes difficult to perform a stop operation at an appropriate timing within the range of the shortened maximum delay time, if the stop operation at an appropriate timing is performed, the first small combination display result or the second small combination display Since the result can be derived, the technical intervention of the player is enhanced, and the game performance can be improved.

  Here, the number of valuable values given by deriving the second small combination display result is larger than the number of valuable values given by deriving the second small combination display result. However, when controlled to the special gaming state, priority is given to identification information that can be used to derive identification information that can be used to derive the second small role display result on the variable display unit corresponding to the detection of the operation of the stop operation means. Therefore, the first small combination display result is more preferentially derived than the second small combination display result, and the player does not suffer a loss.

  In addition, as long as the display mode is such that both the first small combination display result and the second small combination display result can be derived, the first small combination display is displayed on the variable display unit corresponding to the detection of the operation of the stop operation means. Since the identification information capable of both the derivation of the result and the derivation of the second small combination display result is derived, the profit for the derivation of the first small combination display result is not lost until the final display result is derived. . In addition, even when it is not possible to derive the identification information that can derive the second small combination display result in the variable display unit corresponding to the operation of the stop operation means, the identification information that can derive the first small combination display result is provided. Thus, even if it is impossible to derive the second small combination display result, the profit for deriving the first small combination display result is not lost.

  It is to be noted that all of the plurality of variable display units are specially configured such that the maximum delay time from the detection of the operation of the stop operation means to the stop of the variation display of the identification information is reduced to the second maximum delay time in the special gaming state It may be a variable display portion. In addition, the display result of the variable display device refers to the final display mode when all the variable displays in the plurality of variable display units are stopped, and the simple display mode includes other than the final display result. Also, the display mode when the variable display in some of the variable display units is stopped and the variable display in the other partial variable display units is continued.

In the slot machine according to the first aspect,
The variable stop control means is provided in a last variable display section (first and second reels) that is stopped before a final variable display section (third reel) to be finally stopped among the plurality of variable display sections. It is also possible to include a last stop control means for stopping the variation display of the identification information. In this case,
The final pre-stop control means includes
When a display mode (bell temper) constituting a part of the first small role display result is derived as the display mode of the pre-final variable display unit, the display mode derives the second small role display result. When the variable display in the final variable display unit is stopped, the display result determined to be not derived in the special game state can be unavoidable (FIGS. 10A to 10C). Impossible pattern determination means for determining whether or not
When it is determined by the disabling pattern determination means that the disabling pattern does not occur, the first small combination display result within the range of the maximum delay time determined for the variable display unit corresponding to the detection of the operation of the stop operation means A non-impossible stop control means for deriving the first small combination display mode constituting part of
When the disabling pattern determining means determines that the disabling pattern is obtained, the first variable display section is stopped regardless of the operation timing of the stop operation means corresponding to the final variable display section when stopping the variable display on the final variable display section. And a disabling stop control means for deriving a display mode (FIG. 10 (d)) other than the disabling pattern to the pre-final variable display section on the condition that the small combination display result can be derived. be able to.

  Here, when deriving the identification information to the pre-final variable display unit, it is determined whether or not the display pattern constituting a part of the first small combination display result is an impossible pattern. Here, when it is determined that the disabling pattern does not occur, the first small combination display mode is derived to the pre-final variable display section. Therefore, until the final display result is derived, There is no loss of derivation benefits. On the other hand, when it is determined that the non-impossible pattern is not obtained, display modes other than the impossible pattern are derived to the pre-final variable display unit. For this reason, the inconvenience that the display result determined not to be derived in the special gaming state is finally derived cannot occur. However, since the display mode other than the impossible pattern is derived on the condition that the second small role display result can be finally derived, the display mode other than the impossible pattern is derived. Even if the profit for the derivation of the first small combination display result is lost, the derivation of the second small combination display result can obtain a profit larger than this, so that the player is not disadvantaged.

In the slot machine according to the first aspect,
The derivation permitting means is capable of playing a game without using a valuable value that can be used for setting the wager number according to the result of the predetermined lottery when the special gaming state is controlled. It is allowed to allow a replay display result (replay) accompanied by a game to be derived as a display result of the variable display device. here,
The special variable display unit re-enters within a range that can be derived in the second maximum delay time from the identification information arranged next to the position where the re-game identification information (JAC) constituting the re-game display result is arranged. The game identification information is not arranged, and the small combination identification information (bell) constituting the first small combination display result or the second small combination display result can be arranged,
The variation stop control means allows the derivation permission means to permit the derivation of the replay display result, and the special variable display section does not stop the variable display, and the special variable display section recognizes the regame identification. The replay display result can be derived by deriving information, and the identification information from which the first small role display result or the second small role display result can be derived by deriving the small role identification information. When the replay display result is derived in the range of the second maximum delay time in the special variable display unit when the variable display unit is derived to the variable display unit that has stopped the variable display, the regame display result is obtained. When the re-game identification information is derived, the re-game identification information is derived, and when the re-game display result cannot be derived by deriving the re-game identification information, the first combination identification information is derived. When the useful display result or the second Small Win display result is derivable may be made to derive the small role identity.

  Here, since the special game state is terminated by the number of valuable values paid out, even if it is allowed to derive the re-game display result, the bet number is simply set in the next game. In other words, it is possible to avoid spending valuable value and not to lose and gain, and only to extend the time controlled in the special gaming state. On the other hand, even if derivation of the replay display result is permitted, the special game state will be terminated earlier by deriving the small role display result without deliberately deriving this, so the regame display result The game is also caused by not letting out. For this reason, technical intervention by the player is enhanced, and the interest of the game can be improved.

In order to achieve the above object, a slot machine according to the second aspect of the present invention provides:
By setting a predetermined number of bets for one game, the game can be started, and a plurality of variable display units (reels 3L, 3C, 3R) that display a plurality of types of identification information that can be distinguished from each other are variably displayed. In a slot machine in which one game is completed when a display result is derived to a variable display device (variable display device 2) including), and a winning can be generated according to the display result derived to the variable display device.
Derivation permitting means for allowing a predetermined lottery to be performed before the display result of the variable display device is derived and allowing a winning display result to be derived as a display result of the variable display device according to the result of the predetermined lottery. (Step S3, Steps S505 to S523),
Fluctuating display control means (step S4) for fluctuating and displaying identification information in each of the plurality of variable display portions;
Stop operation means (stop buttons 12L, 12C, 12R) for instructing to stop the variable display of the identification information on the plurality of variable display sections by the player's operation,
Stop operation detection means (stop switches 42L, 42C, 42R) for detecting the operation of the stop operation means corresponding to each of the plurality of variable display sections;
A plurality of types of tables (FIG. 11: reel control table) in which the relationship between the identification information displayed on the variable display unit corresponding to the detection of the operation of the stop operation means and the identification information to be derived to the variable display unit is registered. A table selecting means (step S524) for selecting a table corresponding to the type of winning display result permitted to be derived by the derivation permitting means until the stop operating means can be operated;
When the stop operation detection unit detects an operation of the stop operation unit for each of the plurality of variable display units, identification in the variable display unit corresponding to the detection of the operation according to the table selected by the table selection unit Fluctuation stop control means (step S5, steps S701 to S711) for stopping fluctuation display of information,
When a predetermined transition condition is satisfied, the maximum delay time from the detection of the operation of the stop operation means to the stop of the variation display of the identification information in the special variable display unit among the plurality of variable display units is set in the normal gaming state. Special gaming state control means for shifting the gaming state to a special gaming state (CT) that is shortened to a second maximum delay time (75 milliseconds) shorter than the first maximum delay time (190 milliseconds);
In the game controlled to the special gaming state, the derivation permitting means includes a first small combination display result (bell) accompanied by at least a first predetermined number of valuable values and a second larger than the first predetermined number. Allowing a second small role display result (cherry) with a predetermined number of valuable values to be derived as a display result of the variable display device;
When the table selection means is controlled to the special gaming state, the maximum delay determined for the variable display section from the identification information displayed on the variable display section when the operation of the stop operation means is detected. When there is no identification information that can be derived within the time range and the second small role display result can be derived within the maximum delay time range, the first small role display result can be derived. If there is identification information that can derive both the first small combination display result and the second small combination display result within the range of the maximum delay time, the first small combination display result and the It is characterized by selecting a table in which identification information that can derive both of the two small combination display results is registered.

  In the slot machine according to the second aspect, in the special gaming state, the maximum delay time in the special variable display unit is shortened, but at least the first small role display result and the second small role display result are always allowed to be derived. Has been. Here, although it becomes difficult to perform a stop operation at an appropriate timing within the range of the shortened maximum delay time, if the stop operation at an appropriate timing is performed, the first small combination display result or the second small combination display Since the result can be derived, the technical intervention of the player is enhanced, and the game performance can be improved.

  Here, in the table selected in the special gaming state, the identification information that can derive both the first small combination display result and the second small combination display result within the range of the maximum delay time for each variable display unit. When there is, the identification information that can derive both the first small combination display result and the second small combination display result is the identification information that can derive the second small combination display result within the range of the maximum delay time. When there is not, identification information from which the first small combination display result can be derived is registered. In this way, the possibility of deriving the first small combination display result is continued as much as possible while giving priority to deriving the second small combination display result. Since the number of valuable values given by deriving the second small combination display result is larger than the number of valuable values given by deriving the second small combination display result, the first small combination is more than the second small combination display result. The display result is preferentially derived and the player does not suffer a loss.

  In addition, in the table selected here, the variable corresponding to the detection of the operation of the stop operation means is possible as long as the display mode is such that both the first small combination display result and the second small combination display result can be derived. Since the display unit derives identification information that allows both the first small role display result and the second small role display result to be derived, the first small role display result is displayed until the final display result is derived. There is no loss of derivation. Even if there is no identification information from which the second small combination display result can be derived, the identification information from which the first small combination display result can be derived is registered, so that the second small combination display result cannot be derived. However, the profit for deriving the first small combination display result is not lost.

  Also in the slot machine according to the second aspect, all of the plurality of variable display units have a maximum delay time from the detection of the operation of the stop operation means to the stop of the variation display of the identification information in the special game state. It may be a special variable display section that is shortened to the second maximum delay time. In addition, the display result of the variable display device refers to the final display mode when all the variable displays in the plurality of variable display units are stopped, and the simple display mode includes other than the final display result. Also, the display mode when the variable display in some of the variable display units is stopped and the variable display in the other partial variable display units is continued.

  Further, the table shows the operation of the stop operation means as a relationship between the identification information displayed on the variable display unit corresponding to the detection of the operation of the stop operation unit and the identification information to be derived to the variable display unit. The identification information to be derived in the variable display unit, such as the number of sliding frames from the identification information displayed on the variable display unit corresponding to the detection to the identification information to be derived, the number and ID unique to the identification information to be derived, etc. It can be assumed that registered positions and the like are registered. Regardless of which method is registered in the table, the information registered in the table indicates the identification information to be derived, which is the same as that in which the identification information to be derived is registered.

In the slot machine according to the second aspect,
When the table selection means is controlled to the special gaming state, the table selection means is stopped before the last variable display portion (third reel) to be finally stopped among the plurality of variable display portions. As the identification information to be derived to the display unit (first and second reels), when the variable display in the final variable display unit is stopped, regardless of the operation timing of the stop operation means corresponding to the final variable display unit, It is a display mode capable of deriving a second small combination display result, and identification information constituting a first small combination display mode (bell temper) constituting a part of the first small combination display result is registered A special table can be selected. here,
The special table inevitably derives a display result that is determined not to be derived in the special game state when the variable display in the final variable display unit is stopped to derive the second small combination display result. Registered as identification information to be derived in the pre-final variable display section in the display mode other than the impossible patterns (FIGS. 10A to 10C) that constitute the first small role identification information It can be.

  In this case, the special table has a display mode in which the second small combination display result can be derived regardless of the operation timing of the stop operation means corresponding to the final variable display section, and the first small combination display result is displayed. The identification information which comprises the 1st small combination display aspect which comprises a part is registered. Therefore, until the final display result is derived, neither the profit for deriving the first small combination display result nor the profit for deriving the second small combination display result is lost. However, since such a display mode is supposed to be a display mode other than the impossible pattern, there is an inconvenience that a display result determined not to be derived in the special gaming state is finally derived. It can't happen.

  When the second small combination display result is derived according to the identification information derived to the final variable display unit irrespective of the display mode derived to the pre-final variable display unit. The pre-final stop control means can cause the pre-final variable display unit to derive any display mode other than the disabling pattern (which may be a part of the first small combination display result).

  On the other hand, when the second small combination display result is derived according to the identification information derived to the final variable display unit by a combination with the display mode derived to the pre-final variable display unit The previous stop control means stops the variable display in the last variable display unit corresponding to the detection of the operation of the stop operation means by deriving identification information which is a display mode constituting the second small combination display result. It can be made to. However, in the pre-final variable display unit corresponding to the detection of the operation of the stop operation means by deriving identification information which is a display mode constituting the second small combination display result and which is a display mode other than the impossible pattern The variable display is stopped.

In the slot machine according to the second aspect,
The derivation permitting means is capable of playing a game without using a valuable value that can be used for setting the wager number according to the result of the predetermined lottery when the special gaming state is controlled. It is allowed to allow a replay display result (replay) accompanied by a game to be derived as a display result of the variable display device. here,
The special variable display unit re-enters within a range that can be derived in the second maximum delay time from the identification information arranged next to the position where the re-game identification information (JAC) constituting the re-game display result is arranged. The game identification information is not arranged, and the small combination identification information (bell) constituting the first small combination display result or the second small combination display result can be arranged,
When the table selection means is controlled to the special gaming state and the derivation permitting means permits the derivation of the replay display result, the replay within the range of the second maximum delay time. The replay identification information is derived when the display result can be derived, and the first small role display result or the second small role display result is derived when the regame display result is not derivable. When a possible display mode is selected, a table in which the small role identification information is registered as identification information to be derived by the special variable display unit may be selected.

  Here, since the special game state is terminated by the number of valuable values paid out, even if it is allowed to derive the re-game display result, the bet number is simply set in the next game. In other words, it is possible to avoid spending valuable value and not to lose and gain, and only to extend the time controlled in the special gaming state. On the other hand, even if derivation of the replay display result is permitted, the special game state will be terminated earlier by deriving the small role display result without deliberately deriving this, so the regame display result The game is also caused by not letting out. For this reason, technical intervention by the player is enhanced, and the interest of the game can be improved.

The slot machine according to the first and second aspects is as follows.
A plurality of types of permissible stages having different percentages in which the winning display result is derived by the predetermined lottery by the deriving permission unit based on an operation of a predetermined setting operation unit (setting key switch 92, setting switch 91). (Step S201 to S210) an allowable stage setting means (step S201 to S210) for selecting and setting one of the allowable stages from the set value;
Before the predetermined lottery by the derivation permitting means, the slot machine includes numerical data updated within a predetermined range at a predetermined timing as determination numerical data (random number for internal lottery) for each game. Numerical data input means (step S601) for inputting into the determination area provided in the storage means;
A determination indicating the number of determination values that are allowed to be derived by the predetermined lottery by the deriving permission means for the determination numerical data input to the determination area for any one or more types of winning display results Stores the value data (number of judgment values) in common for the plurality of types of allowable stages (common flag is set),
About two or more types of winning display results for which determination value data is not stored in common in the permission stage, the determination numerical data input to the determination area is derived by the predetermined lottery by the derivation permission means. Determination value data storage means for storing determination value data indicating the number of determination values to be allowed individually (common flag is not set) according to the type of the allowable stage (FIG. 6 (c): role classification A judgment value number table, FIG. 7: a judgment value number storage area). In this case,
The derivation permitting means receives the judgment numerical data input to the judgment area in accordance with the judgment value data stored in the judgment value data storage means corresponding to the tolerance stage set by the tolerance stage setting means. The predetermined lottery can be performed by determining whether or not derivation is permitted for each type of winning display result (steps S505 to S551, S515 to S521).
The determination value data storage means includes different number determination value data (a big bonus, a challenge bonus, a bet of 3 bells) indicating the number of different determination values as determination value data to be stored individually according to the type of the permissible stage. The same number determination value data (cherry with 3 bets) indicating the number of the same determination values as the determination value data stored separately according to the type of the permissible stage is stored according to the type of the winning display result. Can be.

  In the slot machine according to the first and second aspects, the determination value data storage means stores determination value data in common with a plurality of types of allowable stages for any one or more types of winning display results. Thus, for one or more types of winning display results in which determination value data is stored in common for a plurality of types of allowable stages, the storage capacity required for storing the determination value data may be small.

  On the other hand, the determination value data storage means stores determination value data individually for the other two or more types of winning display results according to the types of allowable stages. This includes the same number of determination value data indicating the number of the same determination values as the determination value data individually stored according to the type of the permissible stage. Judgment value data determines the probability that the pre-determining means decides to allow the derivation of each winning display result according to the allowable stage. In general, the simulation is performed while adjusting to (the initial judgment value data may be different or may be the same). Appropriate judgment value data obtained as a result of simulation is applied to a model for mass production.

  Here, even if the determination value data becomes the same regardless of the allowable stage as a result of performing the simulation while changing the determination value data according to the allowable stage, such a type of winning display result is not changed. The judgment value data may be stored individually according to the type of the allowable stage. In addition, when the judgment value data is initially stored as the same number of judgment value data indicating the same judgment value individually according to the type of the permissible stage, the judgment value data that is initially registered according to the simulation result remains unchanged. If so, it can be stored in the determination value data storage means as it is as the same number of determination value data. When there is a problem with the judgment value data initially registered as a result of the simulation, the judgment value data can be changed in accordance with the allowable stage and stored in the judgment value data storage means as different number judgment value data. For this reason, since the storage mode of the judgment value data in the development model can be used as it is in the mass production model, development from the initial design stage to the mass production model can be easily performed.

  Note that storing the judgment value data individually according to the types of allowable stages does not necessarily mean that the judgment value data is stored individually for the number of types of allowable stages. If the judgment value data is not stored in common, the data is included in this. For example, when there are six types of allowable stages (first stage to sixth stage), the determination value data is also allowed in the cases where the first to third stages are common and the fourth to sixth stages are common. Depending on the type, it is stored separately.

The slot machine according to the first and second aspects is as follows.
Game control means (game control board 101 (especially CPU 111)) for controlling the progress of the game by program control,
A pulse generation circuit (pulse generation circuit 115a) for generating a pulse signal of a predetermined frequency;
An n-bit (n is an integer greater than or equal to 2) array data signal is inverted alternately between the first level and the second level every time a pulse signal is input from the pulse generation circuit, and Each time the level of the (m-1) th bit (m is an integer of 2 or more: m ≦ n) from the lower level is inverted from the first level to the second level, the level of the mth bit from the lower level is changed to the first level. Counter circuits (lower counter 115b and upper counter 115c) that alternately invert and output at two levels can be further provided.

  In the fourth pattern, the numerical data for determination used for the predetermined lottery of the derivation permitting means does not use the numerical data corresponding to the data signal generated by the counter circuit as it is, but first the data generated by the counter circuit. The numerical data in which the order of the lower n bits of the signal is changed is set as the specified upper numerical data, and the numerical data in which the order of the upper n bits is changed is stored as the specified lower numerical data in the specified upper area and the specified lower area, respectively. Yes. Then, an exclusive OR operation of the numerical data stored in the specific lower area is performed as a predetermined operation on the numerical data stored in the specific upper area.

  By the way, the numerical data corresponding to the data signal generated by the counter circuit has a continuous value every time the pulse signal is input. In the numerical data in which the upper n bits and the lower n bits of the data signal generated by the counter circuit are exchanged, the value is more varied than the numerical data corresponding to the data signal generated by the counter circuit. The value will be periodic. Furthermore, even in numerical data in which the order of bits is different, the periodicity remains in the change in value.

  On the other hand, as in the numerical data for determination in the slot machine of the present invention, the exclusive OR operation with the numerical data stored in the specific lower area for the numerical data stored in the specific upper area, By using this as the upper n-bit data in particular, it is possible to eliminate the periodicity remaining in the numerical data composed of the specific upper numerical data and the specific lower numerical data. Thereby, even if the determination value that determines that the derivation of the winning display result is allowed is set in a range in which the value is continuous over two or more, the player does not aim for the determination of the predetermining means. Can be prevented.

  Depending on the configuration of the game control means, it may not be possible to perform an operation such as an exclusive OR operation using the specific upper area and the specific lower area provided in the storage means as they are. For example, in the case where the game control means is constituted by a microcomputer having a one-address instruction set, the numerical data input means loads numerical data of a specific upper area into an accumulator (general-purpose register), and the numerical data of the accumulator Is subjected to an exclusive OR operation with the numerical data in the specific lower region, and the numerical data obtained as a result of the operation is stored in the accumulator, and the numerical data stored in the accumulator is input to the upper n bits of the determination region. Here, when the numerical data of the specific upper area is loaded into the accumulator, the accumulator acts as the specific upper area.

  In the storage unit, the specific upper area and the specific lower area may be the same as the determination area. For example, when the numerical data of the specific lower area is exclusive ORed with respect to the numerical data of the specific upper area for each bit, and the numerical data of the result is stored in the specific upper area, the specific upper area is That is, the upper n bits of the determination area.

The slot machine according to the first and second aspects is as follows.
A plurality of types of permissible stages having different percentages in which the winning display result is derived by the predetermined lottery by the deriving permission unit based on an operation of a predetermined setting operation unit (setting key switch 92, setting switch 91). (Step S201 to S210) an allowable stage setting means (step S201 to S210) for selecting and setting one of the allowable stages from the set value;
Data storage means (RAM 112) for storing data for controlling the progress of the game including data indicating the allowable stage set by the allowable stage setting means in a readable and writable manner;
Stored data determination means (steps S104 and S105) for determining whether or not the data stored in the data storage means is normal;
Disabling means for disabling the progress of the game when the stored data determining means determines that the data stored in the data storing means is not normal (step S106 (NO), step S301),
In a state where the progress of the game is disabled by the disabling means, the progress of the game is performed on the condition that the allowable stage is newly set by the allowable stage setting means based on the operation of the setting operation means. It is possible to further include disabling canceling means (step S111, FIG. 11) for canceling the disabled state and allowing the game to proceed.

  In this case, when the data stored in the data storage means is not normal, the game cannot be progressed properly because the proper game cannot be progressed. It is necessary to initialize the data stored in the data storage means in order to cancel the state where the game cannot be progressed here. In this case, the data indicating the allowable stage is also initialized. End up. However, in the slot machine, the state in which the game cannot be progressed based on the data in the data storage means being normal is canceled unless a new allowable stage is set based on the operation of the setting operation means. There is nothing. For this reason, since it is ensured that the game is played based on the newly set allowable stage, the fairness of the game can be achieved.

Here, when the predetermined lottery is performed, the derivation permission unit reads data indicating the allowable level stored in the data storage unit, and the data indicating the read allowable level is read by the allowable level setting unit. It is possible to include an allowable level data determination unit (steps S502 and S503) for determining whether or not the data is appropriate data indicating the allowable level that can be set. In this case,
The disabling means can disable the progress of the game even when the allowable stage data determination means determines that the data indicating the allowable stage read from the data storage means is not appropriate data ( Step S503 (NO), step S301).

  Here, even when the determination is made by the range determination means included in the prior determination means, the allowable stage stored in the data storage means is read out to determine whether the allowable stage is appropriate. If the allowable stage is not appropriate, the game cannot be progressed properly because the game cannot be progressed properly. Here, in a state where the progress of the game is disabled based on the fact that the allowable stage stored in the data storage means is not within an appropriate range, a new allowable stage must be set based on the operation of the setting operation means. It will not be released. For this reason, since it is ensured that the game is played based on the newly set allowable stage, the fairness of the game can be achieved.

In the slot machine according to the first and second aspects,
The plurality of variable display units include a reel (reels 3L, 3C, and 3R) in which the plurality of types of identification information are arranged on an outer peripheral surface, and a stepping motor (reel motors 3ML, 3MC, and 3ML (stepping motors) that rotate the reel. Each including a motor 3M)). in this case,
The variation display control means applies a predetermined driving voltage to the stepping motor and excites a plurality of excitation phases (φ1 to φ4) of the stepping motor in a predetermined order, thereby driving the stepping motor in units of the driving step. The reel is rotated (FIG. 13 (until timing ta)),
The fluctuation stop control means performs two-phase excitation control in which a first drive voltage is applied to the stepping motor to excite both the first excitation phase and the second excitation phase adjacent to each other among the plurality of excitation phases of the stepping motor. (FIG. 13 (timing ta to tb), FIG. 20: Step S706), a second drive voltage higher than the first drive voltage is applied to the stepping motor, and the second excitation phase, Three-layer excitation control is performed to excite the third excitation phase adjacent to the second excitation phase and the fourth excitation phase at a position opposite to the second excitation phase and the rotor of the stepping motor (FIG. 13). (Timing tb to tc), FIG. 20: Step S708), the rotation of the reel can be stopped.

  According to such a configuration, the first driving voltage is applied to the stepping motor to perform the two-phase excitation control, and then the second driving voltage higher than the first driving voltage is applied to the stepping motor. Phase excitation control is performed. As a result, it is possible to shorten the time for performing the three-phase excitation control, suppress the vibration when the reel is stopped, and improve the accuracy of the reel stop control.

  The power supply board 100 sets a winning probability for an internal lottery to be described later, and a setting switch 91 and a setting switch 91 for changing setting values (setting 1 to setting 6) of medal payout rates calculated based on the probability. Are connected to a setting key switch 92 for enabling the operation, a second reset switch 93 for resetting the internal state (RAM 112), and a main switch 94 for switching the power ON / OFF, and detection of these switches. A signal is sent to the game control board 101. These switches 91 to 94 are provided inside the slot machine 1.

  The game control board 101 is a control board on the main side that controls the overall flow of the game in the slot machine 1, and includes a control unit 110 including a CPU 111, a RAM 112, a ROM 113, and an I / O port 114. It is installed. Further, a random number generation circuit 115, a sampling circuit 116, a power supply monitoring circuit 117, a reset circuit 118, and other circuits are mounted.

  The CPU 111 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 113 to perform processing related to the progress of the game, and in the slot machine 1 Control each part of the control circuit directly or indirectly. One word of data handled by the CPU 111 is 8 bits (1 byte), and the addresses of the RAM 112 and the ROM 113 are also assigned in units of 8 bits.

  The RAM 112 is used as a work area when the CPU 111 executes a program. The ROM 113 stores programs executed by the CPU 111 and fixed data. The allocation of the addresses of the RAM 112 and the ROM 113 is different between the development model in the manufacturer and the mass production model delivered to the hall. The I / O port 114 inputs and outputs control signals to and from each circuit connected to the game control board 101.

  The RAM 112 uses a DRAM (Dynamic RAM), and requires a refresh operation to maintain the stored data contents. The CPU 111 is provided with a refresh register for performing this refresh operation. The refresh register is composed of 8 bits, which is the size of one word, and the lower 7 bits are automatically incremented every time the CPU 111 fetches an instruction from the ROM 113, and the value is updated by 1 instruction. It is performed at every execution time. The configuration of the RAM 112 area will be described later.

  The random number generation circuit 115 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 116 acquires the numerical value counted by the random number generation circuit 115. . The random number generation circuit 115 is provided for each type of random number used for the progress of the game, and a range of numerical values to be counted for each type of random number is determined. The CPU 111 sends an instruction to the sampling circuit 116 according to the processing to acquire the numerical value indicated by the random number generation circuit 115 as a random number (hereinafter, this function is referred to as a hardware random number function). As a random number for internal lottery described later, a numerical value obtained by processing a numerical value extracted by the hardware random number function by software is used.

  The power monitoring circuit 117 monitors the power supply voltage supplied from the power supply substrate 100, and outputs a voltage drop signal to the control unit 110 when detecting a voltage drop. Although not particularly shown, the control unit 110 includes an interrupt input terminal connected to the power supply monitoring circuit 117, and an external interrupt is generated in the CPU 111 when a voltage drop signal is input to the interrupt input terminal. The CPU 111 executes a power interruption process described later.

  The reset circuit 118 outputs a reset signal when the voltage rises to a level at which the control unit 110 can be activated when the power is turned on to start the control unit 110, and generates a signal periodically output from the control unit 110. When the count is incremented without being cleared based on the reset counter, that is, when the control unit 110 does not operate for a certain time, a reset signal is output to the control unit 110 and the control unit 110 is restarted. .

  The CPU 111 also has a function of updating the numerical value of the specific address in the RAM 112 by 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 111 transmits various commands to the effect control board 102 via the I / O port 114. Each of these commands consists of 8 bits. Note that information (commands) is sent from the game control board 101 to the effect control board 102 only in one direction, and no information (commands) is sent from the effect control board 102 to the game control board 101.

  Connected to the game control board 101 are a single BET switch 45, a MAXBET switch 46, a start switch 41, stop switches 42L, 42C, 42R, a settlement switch 47, a first reset switch 48, and a throw-in medal sensor 44. Detection signals from the switches / sensors are input. In addition, detection signals of the reel sensors 3SL, 3SC, and 3SR are input via the reel relay substrate 103. In accordance with the detection signals of these switches / sensors input via the I / O port 114 or the detection signals of various switches input via the power supply board 100 as described above, the CPU 111 on the game control board 101 Processing is in progress.

  The game control board 101 also includes a flow path switching solenoid 49, a game number display 51, a credit display 52, a payout display 53, a loading instruction lamp 59, a single betting lamp 54, two betting lamps 55, 56, Three betting lamps 57 and 58, a game over lamp 63, a start lamp 60, a replay lamp 62, BET button lamps 70a and 70b, and operation valid lamps 63L, 63C, and 63R are connected, and the CPU 111 follows the progress of the game. These operations are controlled.

  The game control board 101 is connected to reel motors 3ML, 3MC, and 3MR via a reel relay board 103. The CPU 111 controls the reel motors 3ML, 3MC, 3MR via the reel relay substrate 103 and stops the reels 3L, 3C, 3R with reference to a winning flag set in the RAM 112 by an internal lottery described later. The configuration and stop control of the reel motors 3ML, 3MC, 3MR will be described in detail later. An effect control board 102 is further connected to the game control board 101 via an effect relay board 106.

  The effect relay board 106 is a board provided to ensure one-way information transmitted from the game control board 101 to the effect control board 102. The effect relay board 106 does not check the game control board 101 and the effect control board 102 by checking this state, and an illegal signal (especially an external input to the effect control board 102 is input to the control unit 110 of the game control board 101). It is possible to check whether or not a modification has been made such that a signal is input).

  The effect control board 102 is a sub-side control board that controls the execution of effects in the slot machine 1, and is equipped with a control unit 120 including a one-chip microcomputer including a CPU 121, a RAM 122, a ROM 123, and an I / O port 124. Yes. In addition, the random number generation circuit 125 and the sampling circuit 126 are mounted, and the CPU 121 obtains the value counted by the random number generation circuit 125 by the sampling circuit 126, so that the hardware random number function similar to that of the game control board 101 is obtained. Is forming. It also has a software random number function by interrupt processing.

  The CPU 121 executes a program (described later) stored in the ROM 123 to perform processing related to the execution of the effect, and controls each circuit in the effect control board 102 and each circuit connected thereto. The performance is performed based on a command received from the game control board 101 via the I / O port 124. The RAM 122 is used as a work area when the CPU 121 executes a program. The ROM 123 stores programs executed by the CPU 121 and fixed data. The I / O port 124 inputs and outputs control signals to and from each circuit connected to the effect control board 102.

  The effect control board 102 is connected with game effect lamps 75A to 75M, a liquid crystal display 4, speakers 7L, 7R, and 7U, a fluorescent lamp 6, a weight lamp 61, and a bonus notification lamp 66. A reel lamp 3LP is connected via a reel lamp relay substrate 104. The control unit 120 of the effect control board 102 performs these effects by controlling these parts.

  The reel relay board 103 relays between the game control board 101, the external output board 105 and the reel unit 3. The reel relay substrate 103 is also connected with a full sensor 90, and its detection signal is input. The full tank sensor 90 is provided inside the slot machine 1 and detects that the medals in the overflow tank storing the medals overflowed from the hopper 80 are full.

  The reel lamp relay board 104 relays between the effect control board 102 and the reel unit 3. The external output board 105 is connected to an external device such as a hall management computer and receives a big bonus medium signal, regular bonus medium signal, reel control signal, stop signal input from the game control board 101 via the reel relay board 103. The switch signal, medal IN signal, medal OUT signal, and winning status signal are output to the external device.

  Next, the configuration of the RAM 112 of the game control board 101 will be described. FIG. 4 is a diagram showing the configuration of the storage area of the RAM 112. As shown in the figure, the RAM 112 stores an important work 112-1, a general work 112-2, a special work 112-3, a set value work 112-4, a non-saved work 112-5, a stack area 112-6, and a parity storage. A plurality of storage areas including the area 112-7 are provided.

  Among these storage areas, in particular, the set value work 112-4 is an area for storing a set value for determining a winning probability of internal winning to be described later, and the parity storage area 112-7 is a RAM parity at the time of power-off. Is an area for storing An area for setting a winning combination flag to be described later is provided in the general work 112-2. The RAM 112 is supplied with power from a backup power source even in the event of a power failure, and stores stored data.

  In the slot machine 1, 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, a setting value changing operation using the setting switch 91 will be described. In order to change the setting value, it is necessary to turn on the power of the slot machine 1 by the main switch 94 after the setting key switch 92 is turned on. When the slot machine 1 is started without changing the setting value, the setting key switch 92 may be turned off and the power may be turned on by the main switch 94.

  When the setting key switch 92 is turned on and the power is turned on, a setting change mode in which a setting value can be changed is entered. When the setting switch 91 is operated in the setting change mode, the setting value is updated one by one (when further operation is performed from the setting 6, the setting is returned to the setting 1). Then, when the setting key switch 92 is turned OFF after the start lever 11 is operated, the determined setting value after the change is stored in the setting value work 112-4. Then, when the setting key switch 92 is turned off, the state shifts to a state in which the game can proceed.

  When the game can be progressed, the games in the slot machine 1 progress one game at a time, but the set value stored in the set value work 112-4 in the internal lottery performed in each game is within the normal range (1 -6) is determined. When the set value is not within the normal range, it is determined that the RAM is abnormal, and a RAM abnormal error code is set and controlled to a RAM abnormal error state to disable the progress of the game.

  Further, when the CPU 111 of the game control board 101 detects the voltage drop signal, the power interruption processing is executed. In the power interruption processing, the RAM parity is calculated based on all data other than the data stored in the parity storage area 112-7 of the RAM 112, and stored in the parity storage area 112-7. ing. Here, the RAM parity is the least significant bit of the sum total of data strings (bits at the same position in each address).

  When the control unit 110 of the game control board 101 is activated, the RAM parity is calculated based on all data other than the data stored in the parity storage area 112-7 among the data stored in the RAM 112. Compared with the RAM parity stored in the parity storage area 112-7. If the comparison results match, the state before power-off is restored based on the state stored in the RAM 112.

  On the other hand, if the comparison result of the RAM parity does not match, it is determined that the RAM is abnormal again, and the RAM abnormal error code is set to control the RAM abnormal error state, thereby making the progress of the game impossible. ing. Unlike the other error states, the RAM abnormal error state is not canceled even if the first reset switch 48 or the second reset switch 93 is operated, and a new set value is set in the setting change mode. It comes to be canceled by this.

  Next, the configuration of the reel motors 3ML, 3MC, 3MR will be described. Each of the reel motors 3ML, 3MC, 3MR is constituted by a stepping motor. FIG. 5 is a diagram showing the configuration of this stepping motor. The stepping motor 3M (reel motors 3ML, 3MC, and 3MR) is a hybrid stepping motor, and includes a stator 3c and a rotor 3b facing the stator 3c. The rotor 3b has a large number of gear-like projections, and permanent magnets magnetized in the same direction as the rotary shaft 3a are incorporated therein.

  The stepping motor 3M receives a pulse signal (excitation pulse) from the CPU 111 of the game control board 101, and an excitation current sequentially flows in each excitation phase φ1 to φ4 of the stator 3c, and these excitation phases φ1 to φ4 follow a predetermined order. The rotor 3b is rotationally driven by being excited, and the reels 3L, 3C, and 3R are rotated by the rotation of the rotating shaft 3a. As a control method for rotationally driving the stepping motor 3M, a 1-2 phase excitation method is applied here. In the 1-2 phase excitation method, the excitation phases for inputting a pulse signal among the excitation phases φ1 to φ4 are (φ1, φ2), (φ1), (φ4, φ1), (φ4), (φ3, φ4), (Φ3), (φ2, φ3), (φ2), (φ1, φ2)... Are sequentially switched, and the excitation phase for inputting the pulse signal is alternately switched to one phase or two phases. Yes.

  Thus, each time a pulse signal for applying an excitation current to the excitation phases φ1 to φ4 is input, the rotating shaft 3a of the stepping motor 3M rotates by one step. For each of the symbols of the reels 3L, 3C, and 3R shown in FIG. 2, the number of steps of the stepping motor 3M is equally assigned by 16 steps. Therefore, the total number of steps of the stepping motor 3M for rotating the reels 3L, 3C, 3R once is 336 steps.

  The rotation step of the stepping motor 3M is counted by a counter provided in the RAM 112 for each of the reel motors 3ML, 3MC, and 3MR. Further, when the reference position is detected by the reel sensors 3SL, 3SC, 3SR as the reels 3L, 3C, 3R rotate, the counter value is cleared. Therefore, the rotation angles of the reel motors 3ML, 3MC, and 3MR, that is, the symbol positions of the reels 3L, 3C, and 3R can be understood by referring to the counter value (number of steps) counted by the rotation step.

  When stopping the rotation of the stepping motor 3M, the rotor 3b is suddenly braked by two-phase excitation control to be described later in detail according to the target stop position, and then the rotor 3b is stopped by three-phase excitation control to be described later. . As a result, the rotation of the reels 3L, 3C, 3R integrally coupled with the rotors 3b of the reel motors 3ML, 3MC, 3MR is stopped.

  In the slot machine 1, a winning is awarded when the symbols are arranged on the active line set according to the betting number of the variable display device 2. The types of winning combinations are determined according to the gaming status, but can be broadly divided into special roles that involve the transition of gaming status, small roles that involve the payout of medals, and no need to set the number of bets. There is a re-player who can start the next game. 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.

  FIGS. 6A and 6B are diagrams showing a lottery object combination table by gaming state. The lottery target table according to gaming state is stored in advance in the ROM 113 and is used to determine the winning combination determined in the internal lottery. The combination determined as the lottery target according to the is shown. As the lottery target tables by game state, there are a special combination table shown in FIG. 6A and a small combination table shown in FIG.

  In this slot machine 1, special bonuses include big bonus (BB), regular bonus (RB), challenge bonus (CB), single CT (SCT), and small roles such as cherry and bell. Replay is defined as a re-playing role. The special role table is used to determine whether or not to win a special role, and only when the special role winning flag is not set in the normal gaming state or when the gaming state is in CT. Used. The small role table is used to determine whether or not to win a small role and replay, and is used in any gaming state.

  In games where the special role winning flag is not set in the normal gaming state, the special role table and the small role table are used, and the big bonus, regular bonus, challenge bonus, single CT, bell, cherry and replay are eligible for lottery. It becomes. In a game in which the special combination winning flag is set in the normal gaming state, only the small combination table is used, and only the bell, cherry, and replay are targeted for the lottery. In a game in a gaming state of a regular bonus (including a case where it is provided during a big bonus as will be described later), only the small role table is used, and bells and cherries are subject to lottery.

  In a game in the CT gaming state, both the special role table and the small role table are used, and the regular bonus, bell + cherry + replay, and bell + cherry are subject to lottery. However, when a regular bonus is won based on a determination method in a lottery process as will be described later, a bell + cherry is always won. For the winning combination among the winning combinations, the winning flag of the winning combination is set in the RAM 112.

  The regular bonus is awarded when the combination of “BAR-BAR-BAR” is aligned on either the active line in the normal gaming state or CT. When the regular bonus is won, the gaming state shifts from 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 112 (including the case where it is provided during the big bonus described below), and 1 different from the usual bet number is set. The game will be started.

  The big bonus is awarded when a combination of “red 7-red 7-red 7” is aligned 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, the regular bonus is repeatedly provided until the following big bonus termination condition is satisfied. While the gaming state is the big bonus, the big bonus medium flag is set in the RAM 112. The big bonus ends when the number of medals paid out to the player exceeds 345. Here, since the maximum payout number per game is 15, the upper limit of the payout medal number in the big bonus is 360. When the regular bonus in the big bonus exceeds the above-mentioned 345, the regular bonus is terminated together with the big bonus.

  The challenge bonus is awarded when a combination of “white 7-white 7-white 7” is arranged on any of the active lines in the normal gaming state. When a challenge bonus is won, a challenge bonus flag is set in the RAM 112, and the gaming state shifts to CT until the number of payout medals exceeds 238. In the CT gaming state by the challenge bonus winning, the maximum payout number per game is 15, so the upper limit of the payout medal number in the challenge bonus is 253.

  The single CT is awarded when a combination of “JAC-Bell-Cherry” is arranged on any of the active lines in the normal gaming state. When a single CT is won, the SCT flag is set in the RAM 112, and the gaming state shifts to CT for the next one game. Regardless of whether it is a challenge bonus prize or a single CT prize, when the gaming state is CT, 1 is set different from the normal bet number and the game is started. Further, the maximum stop delay time for the right reel 3R is shortened from the normal 190 milliseconds to 75 milliseconds, and the range of the symbols that can be drawn from the symbol position when the stop button 12R is operated is only one frame.

  A bell is awarded when a combination of “bell-bell-bell” is arranged on any of the active lines in any gaming state. Cherry is awarded when the symbol “cherry” is derived to any of the active lines for the left reel 3L in any gaming state. Replay is awarded when a combination of “JAC-JAC-JAC” is available on any of the active lines in the normal gaming state, but this combination is available for regular bonuses (including those offered as big bonuses). Even if you get all of them, you won't get a replay prize. When a replay is won, there is no payout of medals, but the next game can be started without setting the number of bets again. Therefore, the number of bets that became unnecessary in the next game (regular bonus, CT will not be replayed and will always be 3 That is, it is substantially the same as paying out three medals corresponding to the bet number 3 set in the previous game in which the replay winning was generated.

  The only medals to be paid out when winning are the small roles Cherry and Bell. Big bonuses, regular bonuses, challenge bonuses, and single CT winnings are accompanied by a shift in gaming state and are not eligible for payout of medals. When winning the bell, 8 medals are paid out. When winning a cherry, 5 medals are paid out per effective line. That is, when the symbol “cherry” is stopped at the upper or lower stage of the left reel 3L, since the upper or lower stage is included in the three active lines, 15 medals are paid out. When the “cherry” symbol stops in the middle stage, only one medal is paid out because there is only one active line including the middle stage.

  By the way, in a game in which the gaming state is CT, a winning flag of bell or cherry is always set. When the regular bonus or replay winning flag is set in addition to the bell or cherry winning flag, the regular bonus or replay winning is given priority. Thus, the reels 3L, 3C, 3R are controlled to be stopped. Here, “cherry” is arranged at intervals of 7 frames for the left reel 3L, and “cherry” can be stopped at either the upper stage or the lower stage.

  However, when the regular bonus or replay winning flag is set, the reels 3L, 3C, and 3R are controlled to stop as much as possible so that the regular bonus or replay winning is achieved. When the possibility of winning a regular bonus or replay is lost (including the case where these winning flags are not set), the bell should be awarded as much as possible until the left reel 3L is stopped. The reels 3C and 3R are controlled to stop. This has an exception in the case of a forbidden eye to be described later, the details of which will be described later.

  Hereinafter, the internal lottery will be described. The internal lottery is to determine whether or not the winning of each of the above combinations is permitted before the display result of the variable display device 2 is derived and displayed (actually, when the start lever 11 is operated). . In the internal lottery, a random number for internal lottery (an integer from 0 to 16383) is acquired from the random number generation circuit 115. Then, for each combination determined according to the gaming state, the acquired random number for internal lottery, the number of bets set by the player, and each combination determined according to the set value set by the setting switch 91 This is performed according to the number of judgment values.

  The reference of the combination according to the gaming state is performed according to the lottery target table according to gaming state shown in FIGS. 6 (a) and 6 (b). In games where the special role winning flag is not set in the normal gaming state, the special role table and the small role table are used, and the big bonus, regular bonus, challenge bonus, single CT, bell, cherry and replay are eligible for lottery. Are read in order as In a game in which the special combination winning flag is set in the normal gaming state, only the small combination table is used, and only the bell, cherry, and replay are sequentially read out as the combinations to be selected.

  In a game in the regular bonus game state, only the small role table is used, and the bell and cherry are sequentially read out as the lottery target. In the game in the CT gaming state, both the special role table and the small role table are used, and the regular bonus, bell + cherry + replay, and bell + cherry are sequentially read out as the lottery target. Other than the game in the CT gaming state, if it is determined that the read role has been won, other roles will not be read out as the lottery target, but in the game in the CT gaming state, Even if it is determined that the regular bonus is won, Bell + Cherry + Replay and Bell + Cherry are also read out as the draw target.

  In the internal lottery, the number of judgment values determined for the role read as the lottery target is sequentially added to the random number for the internal lottery, and when the result of addition overflows, the winning role is won. It is determined to be a thing. If the winning combination is determined, the winning flag of the combination is set in the RAM 112. The number of determination values is read in accordance with the storage address of the number of determination values registered in the role table stored in advance in the ROM 113. FIG. 6C is a diagram illustrating an example of the role-specific table. The number of determination values may be 256 or more, and cannot be stored for one word. Therefore, each determination value number is registered using a storage area for two words.

  The number of determination values of the combination to be a lottery object is registered corresponding to the number of bets set by the player in the game for each combination. This is because even if the winning combinations are the same, the winning probability in the regular bonus may be different from the winning probabilities in other gaming states. In addition, the number of determination values according to the number of bets of the combination to be a lottery object may be common regardless of the set value, and 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”).

  Since the big bonus is a lottery target in the normal gaming state when the special combination winning flag is not set, the storage address of the number of determination values corresponding to the bet number here is registered. The value of the common flag for this combination is 0, and the storage address for the number of determination values is individually registered according to the set value corresponding to the number of bets. The storage addresses of the determination values for the big bonus with 3 bets are ADD + 0, ADD + 2, ADD + 4, ADD + 6, ADD + 8, and ADD + 10 for the set values 1 to 6, respectively.

  The regular bonus is a lottery target when the special combination winning flag is not set in the normal gaming state and when the gaming state is CT. The value of the regular bonus common flag when the bet number is 3 corresponding to the normal gaming state is 1, and the value of the regular bonus common flag is 1 when the bet number corresponding to CT is 1, both of which are set values. Regardless of the number, the common storage address for the judgment value is registered. The storage address of the regular bonus judgment value number with 3 bets is ADD + 12, and the storage address of the regular bonus judgment value number with 1 bet is ADD + 14.

  Since the challenge bonus is a lottery target when the special game winning flag is not set in the normal gaming state, the storage address of the judgment value number corresponding to the bet number 3 here is registered. . The value of the common flag for this combination is 0, and the storage address for the number of determination values is individually registered according to the set value corresponding to the number of bets. The storage addresses of the determination value number of challenge bonuses with 3 bets are ADD + 16, ADD + 18, ADD + 20, ADD + 22, ADD + 24, and ADD + 26 for the set values 1 to 6, respectively.

  The single CT is a lottery target when the special game winning flag is not set in the normal gaming state, and therefore the storage address of the judgment value number corresponding to the bet number 3 here is registered. . The value of the common flag for this role is 0, and a storage address for the common number of judgment values is registered regardless of the set value. The storage address of the number of determination values for a single CT with 3 bets is ADD + 28.

  The bell is a lottery target when in a normal gaming state and when in a regular bonus gaming state. The common flag value of the bell when the bet number corresponding to the normal gaming state is 3 is 0, but the common flag value of the bell when the bet number corresponding to the regular bonus is 1 is 1. The storage address of the determination value number of the bell with 3 bets is ADD + 30, ADD + 32, ADD + 34, ADD + 36, ADD + 38, and ADD + 40 for each of the setting values 1 to 6. The storage address of the determination value number of the bell with the bet number 1 is ADD + 42.

  The cherry is a lottery target when in a normal gaming state and when in a regular bonus gaming state. The value of the cherry common flag when the bet number corresponding to the normal gaming state is 3 is 0, but the value of the cherry common flag when the bet number corresponding to the regular bonus is 1 is 1. The storage addresses of the determination value number of the cherry with 3 bets are ADD + 44, ADD + 46, ADD + 48, ADD + 50, ADD + 52, and ADD + 54 for each of the set values 1 to 6. The storage address of the determination value number of the bell with the bet number 1 is ADD + 56.

  Since replay is a lottery target in the normal gaming state, the storage address of the number of determination values corresponding to the bet number 3 here is registered. The value of the common flag for this role is 1, and the storage addresses for the common number of judgment values are registered regardless of the set value. The storage address of the replay determination value number with 3 bets is ADD + 58.

  Since Bell + Cherry + Replay is a lottery target in the CT gaming state, the storage address of the number of determination values corresponding to the bet number 1 here is registered. The value of the common flag for this role is 1, and the storage addresses for the common number of judgment values are registered regardless of the set value. The storage address of the determination value number of bell + cherry + replay with 1 bet is ADD + 60. Since Bell + Cherry is also a lottery target when in the CT gaming state, the storage address of the number of determination values corresponding to the bet number 1 here is registered. The value of the common flag for this role is 1, and the storage addresses for the common number of judgment values are registered regardless of the set value. The storage address of the judgment value number of bell + cherry with 1 bet is ADD + 62.

  FIG. 7 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 112 for the development model and in the address area allocated to the ROM 113 for the mass production model.

  For example, the addresses ADD + 0, ADD + 2, ADD + 4, ADD + 6, ADD + 8, and ADD + 10 are addresses that are referred to when the target character of the internal lottery is a big bonus at the set values 1 to 6, respectively, and the winning of the special character in the normal gaming state When the flag is not set, 40, 41, 42, 43, 44, and 45 are acquired as the number of determination values according to the set value, respectively. Similarly, with respect to the challenge bonus, when the special combination winning flag is not set in the normal gaming state from the addresses ADD + 16, ADD + 18, ADD + 20, ADD + 22, ADD + 24, and ADD + 26, 10, 11, 12, 13, 14, and 15 are acquired as the number of determination values.

  The address ADD + 12 is an address that is referred to when the target part of the internal lottery is a regular bonus and the bet number is 3, and is set to a set value when the special part winning flag is not set in a normal gaming state. Regardless, 30 is acquired as the number of determination values. Similarly, for the regular bonus and single CT when the bet number is 1, when the special combination winning flag is not set in the normal gaming state from the addresses ADD + 14 and ADD + 28, respectively, 15, 184 regardless of the set value. Is obtained as the number of judgment values.

  Addresses ADD + 30, ADD + 32, ADD + 34, ADD + 36, ADD + 38, and ADD + 40 are addresses that are referenced when the internal lottery is a bell, the number of bets is 3, and the set value is 1-6. Here, for the bell when the bet number is 3, the number of determination values is individually stored according to the set value, and a different value is stored for each set value. Therefore, in the end, the winning probability of the bell when the bet number is 3 differs depending on the set value. The address ADD + 42 is an address that is referred to regardless of the set value when the target combination of the internal lottery is a bell and the bet number is 1.

  Addresses ADD + 44, ADD + 46, ADD + 48, ADD + 50, ADD + 52, and ADD + 54 are addresses that are referred to when the internal lottery is a cherry, the number of bets is 3, and the set value is 1-6. Here, for the cherries when the bet number is 3, the number of determination values is individually stored according to the set value, but all of the values are 324. Therefore, the winning probability of cherries when the number of bets is 3 is the same regardless of the set value. The address ADD + 56 is an address that is referred to regardless of the set value when the target part of the internal lottery is cherry and the bet number is 1.

  The address ADD + 58 is an address that is referred to when the target role of the internal lottery is replay and the bet number is 3, and 2225 is acquired as the determination value number regardless of the set value in the normal gaming state. The address ADD + 60 is an address that is referred to when the subject of the internal lottery is Bell + Cherry + Replay and the bet number is 1, and 2225 is acquired as the determination value number in CT regardless of the set value. The address ADD + 62 is an address that is referred to when the subject of the internal lottery is Bell + Cherry and the bet number is 1, and 14139 is acquired as the determination value number in CT regardless of the set value.

  FIGS. 8A to 8D 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. FIG. 8A shows an example in which the set value is 6 when the special game winning flag is not set in the normal gaming state. FIG. 8B shows an example in which the set value is 6 when the winning flag for the special combination is set in the normal gaming state. FIG. 8C shows an example when the player is in a regular bonus game state. FIG. 8D shows an example in the CT gaming state.

  For example, as shown in FIG. 8 (a), when the winning flag of the special combination is not set in the normal gaming state, the combination that is the target of the internal lottery is a big bonus, a regular bonus, a challenge bonus, Single CT, bell, cherry, replay. In the set value 6, the number of determination values is 45, 30, 15, 184, 3460, 324, 2245.

  First, the big bonus that is the target of the internal lottery is won when 16339 to 16383, in which the addition result overflows by adding 45 as the determination value number, is acquired as a random number for internal lottery. Next, the regular bonuses that are the subject of the internal lottery add 16309 to 16338, where the addition result overflows by adding 75, which is the sum of 45 big bonus judgment values and 30 regular bonus judgment values. Wins when it is acquired as a random number for internal lottery.

  Similarly, the challenge bonus is determined to be winning when 16294 to 16308 are acquired as internal random numbers and when the single CT and 16110 to 16293 are acquired as internal random numbers. Further, when Bell is acquired as a random number for internal lottery, 12650-16109, Cherry is acquired as a random number for internal lottery, 12326-12649, and replay is performed for internal lottery, 10081-12325. Each is determined to be a winning prize. When 0 to 10080 not corresponding to the above is acquired as a random number for internal lottery, all combinations are lost.

  The approximate winning probabilities calculated for each combination based on the number of judgment values are 1 / 364.1 and 1/546 for each of Big Bonus, Regular Bonus, Challenge Bonus, Single CT, Bell, Cherry, and Replay. .1, 1 / 1092.2, 1 / 89.0, 1 / 4.7, 1 / 50.6, 1 / 7.3.

  Further, as shown in FIG. 8B, when the winning flag for the special combination is set in the normal gaming state, the bell, cherry, and replay are read as the target combinations for the internal lottery. Since Bell, Cherry, and Replay each have 3460, 324, and 2245 decision values, 12924 to 16383, 12600 to 12923, and 10355 to 12599 are acquired as random numbers for internal lottery, and are determined to be winning. The When 0-10354 is acquired as a random number for internal lottery, all the combinations are lost. In addition, the approximate winning probabilities for each combination are 1 / 4.7, 1 / 50.6, and 1 / 7.3.

  In addition, as shown in FIG. 8C, in the regular bonus game state, bells and cherries are read out as internal lottery target roles. Since the determination values of Bell and Cherry are 11424 and 324, when 4960 to 16383 and 4636 to 4959 are acquired as random numbers for internal lottery, they are determined to be winning. When 0 to 4635 are acquired as random numbers for internal lottery, all combinations are lost. In addition, the approximate winning probabilities for each combination are 1 / 1.4 and 1 / 50.6.

  Further, as shown in FIG. 8D, in the CT gaming state, the regular bonus, bell + cherry + replay, and bell + cherry are read out as target roles for internal lottery. Since the regular bonus has a determination value of 15, when 16369 to 16383 are acquired as random numbers for internal lottery, it overflows and is determined to be winning. Since the next bell + cherry + replay has a determination value number of 2245, it is determined that 14124-16368 is won as a random number for internal lottery.

  Bell + Cherry has a determination value of 14139 and is determined to be winning when 0-14125 is acquired as a random number for internal lottery. When 16369-16383 is acquired as a random number for internal lottery, first, the number of regular bonus judgment values is added to overflow the first time and win the regular bonus, but excluding the overflowed carry When the number of determination values of bell + cherry + replay is further added with 14 bits and the determination value of bell + cherry is added, the second overflow occurs here, and it is determined that the bell + cherry is also won. That is, when the gaming state is CT, whatever value is used for the random number for internal lottery, it is determined that at least the bell and cherry are won.

  For a combination determined to be won in the internal lottery, a winning flag for the combination is set in the RAM 112. The big bonus winning flag, the regular bonus winning flag, or the challenge bonus winning flag is carried over after the next game if no winning is generated based on these flags. In other cases, the winning flags for each combination are deleted only for the game. The replay in the CT gaming state may not be won depending on the operation timing of the stop button 12R even if the winning flag is set, but this is also erased only for the game concerned. Since the single CT is not missed depending on the operation timing of the stop buttons 12L, 12C, and 12R, unlike the winning flags of other special roles, the single CT is erased as far as the game concerned.

  Also, even if the Big Bonus Winning Flag, Regular Bonus Winning Flag, or Challenge Bonus Winning Flag is carried over in the normal gaming state, the lottery of the bell, cherry and replay is still held. When winning, the big bonus winning flag, regular bonus winning flag, challenge bonus winning flag and bell, cherry or replay winning flags are set in duplicate.

  Next, acquisition of random numbers for internal lottery will be described in detail. The random numbers for the internal lottery are acquired by extracting random numbers from the random number generation circuit 115 by the hardware random number function and processing them by software by the CPU 111. The least significant bit of the random number extracted from the random number generation circuit 115 or processed from the random number generation circuit 115 is referred to as the 0th bit, and the most significant bit is referred to as the 15th bit.

  First, extraction of random numbers from the random number generation circuit 115 will be described. FIG. 9A is a block diagram showing the configuration of the random number generation circuit 115 in detail. As shown in the figure, the random number generation circuit 115 includes a pulse generation circuit 115a, a lower counter 115b, and an upper counter 115c. The lower counter 115b and the upper counter 115c are both 8-bit (1 byte) counters, the lower counter 115b is the 0th bit to the 7th bit, and the upper counter 115c is a total of 16 bits from the 8th bit to the 15th bit. The data signal is output.

  The pulse generation circuit 115a outputs a pulse signal at a frequency that is higher than the frequency of the operation clock of the CPU 111 and is not an integral multiple thereof (preferably relatively prime). The pulse signal output from the pulse generation circuit 115a is clocked into the lower counter 115b.

  The lower counter 115b 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 115a. 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 115b is clocked into the upper counter 115c.

  The upper counter 115c 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 115b. 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 the 16-bit data signal in which the data signal of the lower counter 115b is the lower 8 bits and the data signal of the upper counter 115c is the upper 8 bits is 0 (0000h) every time the pulse generation circuit 115a 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 115.

  The sampling circuit 116 is configured by a latch circuit, and latches the 16-bit data signal output at that time from the random number generation circuit 115 based on a sampling command from the CPU 111 and outputs the latched data signal. The CPU 111 extracts numerical data corresponding to the data signal input from the sampling circuit 116 via the I / O port 114 as a random number generated by the random number generation circuit 115. Hereinafter, the data signal output from the random number generation circuit 115 will be described as a random number corresponding to the logical value.

  Next, processing of random numbers extracted from the random number generation circuit 115 by software will be described. FIG. 9B is an explanatory diagram until the CPU 111 processes the random number extracted from the random number generation circuit 115 into a random number for internal lottery by software. The random number extracted from the random number generation circuit 115 is stored in a 16-bit general-purpose register 111GR included in the CPU 111.

  When the random number extracted from the random number generation circuit 115 is stored in the general-purpose register 111GR, the CPU 111 uses the other general-purpose register or the work area of the RAM 112 to lower byte of the general-purpose register 111GR (value extracted from the lower counter 115b). And the value of the upper byte (the value extracted from the upper counter 115c) are exchanged.

  Next, the CPU 111 performs an AND operation on the value of the random number obtained by exchanging the upper byte and the lower byte for the extracted random number with 8080h. Since the processing word of the CPU 111 is 1 byte, the logical product operation is actually performed sequentially on the upper byte and the lower byte. The 15th bit and the 7th bit are always 1 by this logical product operation. Further, the CPU 111 shifts the upper 1 byte (8th bit to 15th bit) to the lower bit by bit, and inserts 1 into the empty 15th bit.

  The CPU 111 acquires the value stored in the general-purpose register 111GR at this time as a random number for internal lottery, stores it in a predetermined area of the RAM 112, and determines the determination value (actual value) of each combination registered in the winning determination table. Are sequentially compared with the upper limit judgment value only). Since the 15th and 14th bits of the random number for internal lottery are always 1, the random number for internal lottery is a random number having a size of 14 bits (16384), which is substantially 0 to 16383. It takes a value.

  Note that interrupts to the CPU 111 are prohibited during the period from the extraction of random numbers from the random number generation circuit 115 to the end of processing. This is to prevent the contents of the general-purpose register 111GR from being rewritten in the interrupt processing routine when an interrupt occurs to the CPU 111.

  Next, the forbidden items will be described. When the gaming state is a regular bonus (including a case where the bonus is provided in the big bonus), a big bonus, a regular bonus, a challenge bonus, and a single CT cannot be derived as a display result of the variable display device 2. However, in this gaming state, only the bell or cherry is won, and both are not won at the same time. If the cherry (upper or lower stop) is better than the bell, you can get more payouts, but the left reel 3L will stop last when the cherry win flag is set In addition, since it is not necessary for the middle and right reels 3C and 3R to be in a tempered state where “bells” are aligned on the active line, even if there is a display result that cannot be derived when the gaming state is a regular bonus, it is prohibited. The problem does not occur.

  When the gaming state is CT, a big bonus, a challenge bonus, or a single CT cannot be derived as a display result of the variable display device 2. When the gaming state is CT, at least the bell and cherry winning flags are set at the same time. Therefore, when the left reel 3L is to be stopped at the end, the regular bonus or replay winning flag is also set redundantly. In 3R, the “bell” must be tempered, and in this case, the problem of forbidden eyes arises.

  FIG. 10 is a diagram for explaining prohibited items in the gaming state of CT. As shown in FIG. 10 (a), the left reel 3L is still rotating, "bell" in the middle stage of the middle reel 3C, and "bell", "JAC", " The display mode in which the symbol “cherry” is stopped is forbidden, and this display mode is considered as described below.

  In this case, as shown in FIG. 10B, if the stop button 12L is operated when the “cherry” is positioned at the lower stage of the left reel 3L, the display result of the variable display device 2 is stopped. The symbols that can be displayed are the currently displayed symbol and the four symbols above this symbol. Therefore, in order to win the cherry, the “cherry” located in the lower row must be stopped as it is, but then the symbol combination “JAC-Bell-Cherry” will appear on the diagonal line from the upper left to the lower right. In addition, since the derivation of the single CT display result is inevitable, the display result cannot be derived.

  On the other hand, as shown in FIG. 10 (c), when one frame is drawn, the symbol combination “Bell-Bell-Bell” is aligned on the valley-shaped effective line, and the Bell can be awarded. However, the number of medals to be paid out in the Bell winning is only 8, and it becomes impossible to obtain 15 medals for paying out when “Cherry” is stopped at the upper or lower stage of the left reel 3L. This display result cannot be derived.

  Therefore, control is performed so as not to derive the prohibition as shown in FIG. 10A when the reel 3C being stopped before the left reel 3L or the right reel 3R is stopped. Here, as shown in FIG. 10 (d), when the middle reel 3C is stopped with "white 7" in the upper stage and "bell" in the middle stage, one frame from the upper stage of the variable display device 2 is stopped. It is assumed that the stop button 12C is stopped with the “bell” positioned above. In this case, if the right reel 3R is stopped by drawing one frame within the range of the maximum stop delay time of 75 milliseconds, the “bell” can be tempered on the effective line, as shown in FIG. The forbidden eyes will be derived.

  In this case, it is assumed that the rotation of the right reel 3R is stopped without pulling in the “bell” one frame above the upper stage and without causing the “bell” to be tempered. Even in this case, when the left reel 3L is finally stopped, as shown in FIG. 10 (f), it is guaranteed that “cherry” is stopped at the upper or lower stage and finally 15 payouts are obtained. Therefore, such control that does not cause the “bell” to be tempered becomes possible.

  Next, the reel control table will be described in detail. When the winning flag is set according to the result of the internal lottery described above, when the rotation of the reels 3L, 3C, 3R is stopped according to the setting state of the winning flag (including those carried over from the previous game) A reel control table for selecting a stop symbol is selected. When the gaming state is in CT, the maximum stop delay time of the right reel 3R is shortened to 75 milliseconds, so that stop control different from that in other gaming states is inevitably performed. However, when the gaming state is CT, at least the bell winning flag and the cherry winning flag are set at the same time, and the setting status of such a winning flag is not seen in other gaming states, so according to the setting status of the winning flag A reel control table may be selected.

  Taking the control content related to the left reel 3L as an example of the control content of the reel control table, when the operation of the stop button 12L is detected, the step number (described later) of the reel 3L located in the middle stage of the variable display device 2 is detected. Among the symbols that can be stopped within the drawing range of the symbol and the four frames, a stop step number (described later) of the symbol that should be stopped in the middle stage is registered according to the setting status of the winning flag. In the reel control table applied to the right reel 3R during CT, the registered stop step number is the symbol located in the middle stage of the variable display device 2 or the next one when the operation of the stop button 12R is detected. This is the stop step number of the frame symbol.

  FIG. 11 is a diagram illustrating an example of a reel control table selected for each winning flag setting status and the control contents. In FIG. 11, the control content of the reel control table indicates that the priority of derivation is higher in the display mode shown on the left. For example, “Big Bonus> Lost” in the table selected when only the big bonus winning flag is set is a range of a maximum stop delay time of 190 milliseconds from the operation of the stop buttons 12L, 12C, 12R ( In other words, if the display mode of the big bonus can be derived in the range of 4 frames), the control content for deriving the display mode of the big bonus is written in the table, and if the display mode of the big bonus cannot be derived The control content for deriving the display mode of the loss is always written in the table.

  For example, in the table selected when the cherry winning flag is set at the same time as the big bonus winning flag, the “cherry” finally stops at either the upper or lower stage of the left reel 3L. It will be a thing and you will win a cherry prize. However, when the left reel 3L is the third reel to be finally stopped, the display mode when the inner reel 3C and the right reel 3R serving as the first and second reels are stopped is shown in FIG. The control contents that are not prohibited are written in the reel control table.

  In the reel control table selected at the time of CT, for the left reel 3L and the inner reel 3C, there is a control content in which the symbols positioned at the time of operating the stop buttons 12L and 12C or the symbols up to four frames ahead are stopped symbols. Although written, for the right reel 3R, the control content with the symbol positioned at the time of operation of the stop button 12R or the symbol from this point to one frame ahead as the stop symbol is written.

  Here, in the reel control table that is selected when the replay winning flag, the bell winning flag, and the cherry winning flag are set at the same time, first, the control content that gives priority to the replay winning is written. When the display mode is such that no replay can be won when the left reel 3L is not stopped (here, the right reel 3R is at least stopped), “cherry” is displayed on the upper or lower stage of the left reel 3L. Control details to be stopped are written. When the display mode is such that neither the replay nor the cherry can be won (here, the left reel 3R is at least stopped), the right reel 3R is 75 milliseconds and the middle reel 3C is 190 millimeters. If there is still a possibility of winning a bell in seconds, the control details for winning the bell are written. If it is impossible to win a bell, the control contents for deriving the display result of the loss are written.

  Further, in the reel control table selected when the bell winning flag and the cherry winning flag are set at the same time, the final display result is a control for stopping “cherry” at the upper or lower stage of the left reel 3L. The contents are written. However, when the left reel 3L becomes the third reel, the "bell" is placed on the effective line as much as possible within the range of 75 milliseconds for the right reel 3R and 190 milliseconds for the middle reel 3C. The contents of control to be tempered are written. Of course, if the display mode of the inner reel 3C and the right reel 3R is the prohibition shown in FIG.

  In FIG. 11, the reel control table selected for each winning flag setting situation has been described as having one type for each winning flag setting situation. However, the reel control table is different even if the winning flag setting situation is the same. A type of reel control table may be selected. However, among reel control tables selected when the setting status of the winning flag is the same, even if the symbol combination corresponding to the set winning flag is derived on a different effective line, whether or not there is a win or wins The type of combination needs to be the control content as shown in FIG.

  However, the reel control table selected when the big bonus winning flag, regular bonus winning flag or challenge bonus winning flag and the bell winning flag, cherry winning flag or replay winning flag are set at the same time is a special role. It may be a table in which control contents for deriving a big bonus, regular bonus, or challenge bonus in preference to a bell, cherry, or replay that is not a special role is written. In this case, when the display mode of the big bonus, regular bonus or challenge bonus cannot be derived within the maximum stop delay time of 190 milliseconds from the operation of the stop buttons 12L, 12C, 12R, the bell, cherry or replay When the display mode can be derived, a table in which the control content for deriving the display mode is written may be used.

  The symbols to be stopped by the reels 3L, 3C, 3R are determined according to the reel control table selected according to the setting status of the winning flag, and as a result, the gaming state, the setting status of the winning flag, and the stop buttons 12L, 12C, It is selected according to the operation timing of 12R. However, the actual control of the reels 3L, 3C, and 3R is performed according to the number of rotations of the reel motors 3ML, 3MC, and 3MR to which the reels 3L, 3C, and 3MR are coupled, and is written in the reel control table shown in FIG. The data is also written according to the number of steps, not the symbol number.

  FIG. 12 is a diagram for explaining the relationship between symbols corresponding to symbol numbers “6” to “11” arranged on the outer periphery of the reel 3L and steps for driving the reel motor 3ML. Although only the left reel 3L is shown in FIG. 12, the symbol of the inner reel 3C and the step of the reel motor 3MC and the symbol of the right reel 3R and the step of the reel motor 3MR have the same relationship. It becomes a thing.

  Referring to FIG. 12, when the step number of the reel motor 3ML is “1”, the “cherry” No. 6 out of the symbols put on the reel 3L is on the middle effective line which is the judgment reference position. To position. The step number of the reel motor 3ML corresponds to the number of steps counted by the counter of the RAM 112 when the position corresponding to the step number is on the middle effective line. Further, 16 steps are assigned to each symbol corresponding to the symbols arranged on the reel 3L.

  For example, the symbol “Cherry” of No. 6 is arranged in the range of step numbers 329 to 8 (329, 330,..., 336, 1, 2,..., 8) of the reel motor 3ML. Since the stop step number is 1, by stopping the rotation of the reel motor 3ML so that the number of steps of the counter of the RAM 112 becomes 1, the “Cherry” of No. 6 can be stopped in the middle stage. In addition, the 7th “white 7” symbol is arranged in the range of step numbers 9 to 24 of the reel motor 3ML and the stop step number is 17, so that the number of steps of the counter of the RAM 112 is set to 16. By stopping the rotation of the motor 3ML, No. 7 “White 7” can be stopped in the middle stage.

  Next, the drawing of the reels 3L, 3C, 3R will be described. When a stop signal from the stop switches 42L, 42C, 42R is input to the CPU 111 (that is, when the stop buttons 12L, 12C, 12R are operated), any of the corresponding reels 3L, 3C, 3R is within a retractable range. The symbol of is stopped. For example, as described above, when 4 frames can be drawn, a total of 5 symbols, that is, 16 × 5 = 80 steps or less, including the symbols currently located and the 4 symbols that can be drawn. The symbol corresponding to the step can be stopped. Here, the left reel 3L will be described as an example.

  More specifically, when the number of steps counted for the reel 3L when the stop signal is input from the stop switch 42L is, for example, any of 321 to 336, step number 65 (= 321 + 80-336) Can be pulled in. In the reel control table, one of steps 1, 17, 33, 49 or 65 should stop the symbol in association with step numbers 321 to 336 when the stop signal from the stop switch 42L is inputted. Registered as a number.

  Similarly, when the number of steps counted for the reel 3L when the stop signal is input is any one of 1 to 16, it is possible to pull in the step number 81 (= 1 + 80), and the stop signal from the stop switch 42L. When the number of steps counted for the reel 3L when any of the numbers is 17 to 32, the number up to step number 97 (= 1 + 80) can be drawn.

  Here, the data written in the reel control table will be described in more detail. For example, when the fifth “JAC” is located in the middle stage (that is, the number of steps counted for the left reel 3L is 313 to 313). In the case of 328), the number of steps to be stopped is registered for the number of steps 313 to 328 to be registered in the control content for stopping the seventh “white 7” in the middle.

  As described above, the symbols to be stopped on the reels 3L, 3C, 3R are selected according to the operation timing of the stop buttons 12L, 12C, 12R and the setting status of the winning flag. Actually, the stop positions of the reels 3L, 3C, and 3R are the number of steps registered in the reel control table selected based on the setting status of the winning flag according to the number of steps counted by the counter of the RAM 112. It will be determined at the position of. Hereinafter, a method for controlling the reel motors 3ML, 3MC, and 3MR when the rotation of the reels 3L, 3C, and 3R is stopped with the target number of steps will be described.

  FIG. 13 is a timing chart illustrating a method for controlling the reel motors 3ML, 3MC, and 3MR. The reel motors 3ML, 3MC, and 3MR have the same control method for rotating and the control method at the time of stopping, and here, description will be made as the stepping motor 3M. For example, when the stepping motor 3M corresponds to the reel motor 3ML, this is control for rotating and stopping the reel 3L.

  As shown in the drawing, the reel is rotated by driving the stepping motor 3M by the 1-2 phase excitation method until the condition for stopping the rotating reel is satisfied (until timing ta in the figure). During the period in which the stepping motor 3M is controlled by the 1-2 phase excitation method, the pulse signals for exciting φ1 to φ4 are turned ON / OFF at the timing shown in the figure, as indicated by the circled numerals 1 and 2 in FIG. Along the rotation direction of the rotor 3b, (φ2, φ3), (φ3), (φ3, φ4), (φ4), (φ4, φ1), (φ1) in this order, one phase, two phases, The excitation phase is excited alternately with 1 phase and 2 phase.

  In this 1-2 phase excitation method, for example, (φ1, φ2), (φ2, φ3), (φ3, φ4), (φ4, φ1)... Compared to the method of always exciting only one phase in the order of φ2, φ3, φ4, φ1,..., the step angle can be made finer and fine control can be performed. Also, the 1-2 phase excitation method has fewer signals than other excitation methods, and can shift to a more stable and smooth stop control.

  When a condition for stopping the rotating reel is satisfied (for example, the detection signal from the stop switches 42L, 42C, 42R is received and the stop step specified from the reel control table selected in advance is the middle effective line) When a position where it can be stopped upward is reached), the process shifts to the reel stop control from the state where the two phases are excited. For example, when the condition for stopping the reel is satisfied in the period indicated by the circled numeral 1 in FIG. 13, the process proceeds to stop control after waiting until timing ta at which the two phases are excited.

  The reel stop control is performed in two stages as shown by “T1” and “T2” in FIG. Control performed at “T1” is referred to as “2-phase excitation control”, and control performed at “T2” is referred to as “3-phase excitation control”.

  In the two-phase excitation control, the stepping motor 3M is controlled by the 1-2 phase excitation method from the stage where only one phase is excited to the state where two phases are excited (timing ta in FIG. 13). This control is started and holds the state of exciting the two phases for a predetermined hold time T1. For example, in the case of FIG. 13, the ON state of (φ1, φ2) is held for the hold time T1. Since only the two phases (φ1, φ2) are excited for a predetermined time, the rotor 3b of the stepping motor 3M that has been rotating at high speed is suddenly braked as shown in the graph A. In the two-phase excitation control, the two phases are excited by the first voltage V1 having the same height as the voltage when the stepping motor 3M is controlled by the 1-2 phase excitation method.

  The hold time T1 is determined according to “the amount of overshoot that will cause a step-out”. The amount of overshoot varies depending on the magnitude of the holding torque of the stepping motor 3M, the reel inertia, the spring constant, and the like. For this reason, it is necessary to actually measure (for example, laser measurement) the “overshoot amount that will cause the step-out” after confirming the transient operation.

  In this embodiment, description will be made assuming that the amount of overshoot is four steps of the stepping motor 3M. In this case, the hold time T1 is set as a time required for the reel motor 3M to drive for 3 steps. Then, the target stop angle position of the rotor 3b is set three steps ahead of the stage where the “two-phase excitation control” is started in accordance with the hold time.

  For this reason, at the timing tb when the hold time T1 has elapsed, the rotor 3b is in a position immediately before the target stop angle and the rotational speed is braked. Therefore, the excitation pattern is repeated at timing tb to start “three-phase excitation control”. That is, φ1 is demagnetized, and a stop phase (φ3) corresponding to the stop angle position and two brake phases (φ2, φ4) at opposite positions across the stop phase are excited during the period T2. In the three-phase excitation control, the three phases are excited with the second voltage V2 that is higher than the first voltage V1. As a result, as shown by the solid line in graph A, the rotor 3b stops at the holding torque stable point of the stop phase φ3 while obtaining a brake by the brake phases φ2 and φ4. As a result, the reel integrally coupled with the rotor 3b stops at the target position accurately and without vibrating. Further, by exciting the three phases with the second voltage V2 that is higher than the first voltage V1, the period T2 can be shortened as compared with the case where the voltage is not changed.

  The broken line in graph A shows the transient response operation of the rotor 3b when the two-phase excitation control is continued after timing ta. As shown in the figure, when the two-phase excitation control is continued, the rotor 3b eventually converges to the equilibrium point, but it is unavoidable that the reel vibrates unpleasantly until then.

  After the three-phase excitation control is executed during T2, the brake phases φ2 and φ4 are demagnetized, and the motor voltage is set to the third voltage V3 lower than the first voltage V1 while maintaining the excitation state of the stop phase φ3. The reason why the excitation phase of the stop phase φ3 is maintained even after the rotor 3b is stopped is to prevent the rotor 3b from deviating from the holding torque stable point of the stop phase φ3 due to a phase difference between the holding torque and the detent torque or a shift due to friction. It is to do. As a result, it is possible to prevent the reel from moving finely after being temporarily stopped and from shifting the starting position when starting the reel motor next time.

  Hereinafter, processing in the slot machine 1 according to this embodiment will be described. In the slot machine 1, the game is progressed by repeatedly performing the game process one game at a time. For this purpose, the game must be in a state where the game can be progressed. In order to be able to advance the game, the setting value of the normal range is stored in the setting value work 112-4 with the control unit 110 including the CPU 111 activated, and the data stored in the RAM 112 is stored in the data stored in the RAM 112. The condition is that there is no more.

  FIG. 14 is a flowchart showing a startup process executed by the CPU 111 of the game control board 101. This activation process is a process performed when the reset signal is input from the reset circuit 118 and the control unit 110 is activated. Since the reset signal is a signal that is output when the power is turned on and when the operation of the control unit 110 is stagnant, the activation process is accompanied by the activation of the control unit 110 that accompanies power-on and a malfunction of the control unit 110. This process is performed when restarting.

  In the startup process, first, the built-in device, peripheral IC, stack pointer, and the like are initialized (step S101), and access to the RAM 112 is permitted (step S102). Then, it is determined whether or not the setting key switch 92 is in an ON state (step S103). If the setting key switch 92 is not ON, the RAM parity is calculated based on all the data stored in the RAM 112 except the parity storage area 112-7 (step S104).

  Next, the RAM parity calculated here is compared with the RAM parity stored in the parity storage area 112-7, that is, the RAM parity calculated and stored at the previous power-off (step S105). Whether or not the data stored in the RAM is normal (step S106). In this embodiment, whether or not the RAM 112 is normal based on the RAM parity is determined only in the startup process.

  If the RAM parities do not match in step S106, the data stored in the RAM 112 is not normal, and the routine proceeds to the RAM abnormality error processing shown in FIG. If the RAM parities match, the data stored in the RAM 112 is normal, so the register stored in the stack area 112-6 is restored (step S107), and the interrupt prohibition is canceled (step S107). S108), the process returns to the state before the power is turned off.

  If the setting key switch 92 is ON in step S103, all the data stored in the RAM 112 is initialized except for the area in use in the stack area 112-6 (other than the setting value work 112-4). Is rewritten to 0, and the set value work 112-4 is rewritten to 1) (step S109), the prohibition of interruption is canceled (step S110), and the process proceeds to the setting change process shown in FIG. 15 (step S111). Then, after the setting change process is completed, the game can be progressed and the process proceeds to the game control process.

  FIG. 15 is a flowchart showing in detail the setting change process executed by the CPU 111 in step S111. In the setting change process, first, a setting changing flag indicating that the setting changing mode is being set is set in a predetermined area of the RAM 112 (step S201), and the setting value (setting change) stored in the setting value work 112-4 is set. Before shifting to the processing, the value of the set value work 112-4 has been rewritten to 1, so it is 1 here) (step S202).

  Thereafter, the operation waits for detection of the operation of the setting switch 91 and the start switch 41 (steps S203 and S204). When the operation of the setting switch 91 is detected in step S203, 1 is added to the setting value read in step S202 (step S205), and whether or not the setting value after the addition is 7, that is, whether the normal range has been exceeded. It is determined whether or not (step S206). If the set value after addition is not 7, the process returns to the state of waiting for detection of the operation of the setting switch 91 and the start switch 41 in steps S203 and S204. If the set value after addition is 7, the set value is corrected to 1 (step S207), and the process returns to the state of waiting for detection of the operation of the setting switch 91 and the start switch 41 in steps S203 and S204.

  When the operation of the start switch 41 is detected in step S204, the changed set value selected at that time is stored in the set value work 112-4 and the set value is confirmed (step S208). Thereafter, the process waits until the setting key switch 92 is turned off (step S209). If it is determined in step S209 that the setting key switch 92 has been turned off, the setting changing flag set in step S201 is cleared (step S210). Then, when returning to the flowchart of FIG. 14, the game can be progressed and the game control process is started.

  FIG. 16 is a flowchart showing in detail the RAM abnormality error process executed by the CPU 111 of the game control board 101. In the RAM abnormality error process, the game number display unit 51 is controlled to display the RAM abnormality error code on the game number display unit 21 (step S301), and then the process proceeds to a loop process in which no process is performed.

  As described above, in the startup process, when the setting key switch 92 is not in the ON state, the data stored in the RAM 112 is compared by comparing the RAM parity calculated at the time of power-off with the RAM parity calculated at the time of startup. It is determined whether or not it is normal, and the routine proceeds to RAM abnormality error processing. In the RAM abnormality error process, since the RAM abnormality error code is displayed on the game number display unit 21, the process proceeds to a loop process in which no process is performed, so that the progress of the game is disabled.

  If the RAM parity does not match, the interrupt is not permitted. Therefore, once the process proceeds to the RAM abnormality error process, the setting key switch 92 is activated in the ON state until the interrupt prohibition is canceled. Even if the power is cut off, no power interruption processing is performed. In other words, since no new RAM parity is calculated and stored in the power interruption process, the RAM parity is always set except when the setting key switch 92 is activated even when the control unit 110 is activated. Since they do not match, the control unit 110 cannot be activated to start (resume) the game.

  Once the RAM abnormal error state is entered, the setting key switch 92 is turned on, the setting key switch 92 is turned on, setting change processing is performed, and a new set value is selected and set by operating the setting switch 91 until the game It becomes impossible to progress. That is, in the state that has shifted to the RAM abnormal error mode state, the state in which the game cannot be progressed is canceled and the game is started (resumed) on condition that a setting value is newly selected and set by operating the setting switch 91. ). In the error state other than the RAM abnormal error, there is no problem of the RAM parity mismatch, so that the state where the game cannot be progressed is canceled only by the operation of the first reset switch 48 or the second reset switch 93, and the game is resumed. Can be made.

  As described above, when the game can be progressed, the game processing is repeated one by one in the slot machine 1. Hereinafter, each game in the slot machine 1 will be described. The “game” in the slot machine 1 is, in a narrow sense, from the operation of the start lever 11 to the stop of the reels 3L, 3C, 3R. Since the bet number before the operation is set, the medals are paid out and the game state is shifted after the reels 3L, 3C, and 3R are stopped, these accompanying processes are also included in the “game” in a broad sense. . It should be noted that the transmission of commands from the game control board 101 to the effect control board 102 will be described only for those necessary for the description of the present invention, and the description of the transmission of other commands will be omitted.

  FIG. 17 is a flowchart showing a game control process performed by the CPU 111 of the game control board 101 for each game. This process is also executed after the power is turned on and a predetermined boot process is performed, or immediately after the setting is changed by operating the setting switch 91. When the process of one game is started, first, an initial process including a process of clearing a predetermined area of the RAM 112 is performed (step S401).

  Next, the number of bets is set by operating one BET button 14 or MAXBET button 15 or by inserting medals from the medal insertion slot 13, and operating the start lever 11 to substantially change the game. BET processing for instructing start is performed (step S402).

  Here, when the gaming state is a regular bonus (including a regular bonus in a big bonus) or CT, if the bet number is set to 1 (a bet number larger than this is not set), the start lever 11 is operated effectively. It becomes. In other game states, the start lever 11 becomes effective after 3 is set as the bet number. Further, if the player has won a replay in the previous game, the same number of bets as in the previous game (3 in this embodiment) is automatically set by the replay flag (the replay flag is erased at this stage) and remains as it is. The start lever 11 becomes effective.

  When the number of bets is set by the BET process and the start lever 11 is operated, a random number for internal lottery is extracted, and winning to each combination determined according to the gaming state is allowed based on the extracted random number value A lottery process for determining whether or not to perform is performed (step S403). In this lottery process, a winning flag is set in the RAM 112 based on each lottery result, and a reel control table is selected. Details of the lottery process will be described later.

  When the lottery process is completed, a reel fluctuation start process is performed (step S404). In the reel fluctuation start process, the reels 3L, 3C, and 3R in the previous game are processed on the condition that a predetermined time (for example, 4.1 seconds) has elapsed from the start of rotation of the reels 3L, 3C, and 3R. The motors 3ML, 3MC, and 3MR are driven to start rotation of all the left, middle, and right reels 3L, 3C, and 3R. Thereby, the symbols are variably displayed on the variable display device 2. Here, when a predetermined time has not elapsed since the start of rotation in the previous game, the rotation is awaited for rotation, and the weight display unit 31 is notified by lighting the weight lamp 61. Also, the timing of one game timer for the next game is started.

  Thereafter, reel fluctuation stop processing is performed (step S405). In the reel fluctuation stop process, after a predetermined condition is established from the start of reel rotation (the reference position is detected by the reel sensors 3SL, 3SC, 3SR after the rotation speed reaches a certain speed), the stop buttons 12L, 12C , 12R are made effective, and each is operated by a player to stop driving the reel motors 3ML, 3MC, 3MR with reference to a reel control table preselected according to the setting status of the winning flag, The rotation of 3C and 3R is stopped. Details of the reel fluctuation stop process will be described later.

  When the driving of each of the reels 3L, 3C, 3R is stopped, in the display mode at the time of stopping, whether any of the above-mentioned role symbols is derived and displayed on the active line according to the bet number set in the BET process in step S402 A winning determination process for determining whether or not is performed (step S406). If it is determined in this winning determination process that a winning combination has been won, various processes corresponding to the winnings generated on the game control board 101 are performed.

  When the winning determination process ends, a payout process is performed (step S407). In the payout process, the credit is increased by the number of payouts set in the winning determination process. However, when the number of credits accumulated as data reaches 50, the hopper motor 82 is driven to pay out an excess number of medals from the medal payout slot 71. In addition, various processes that are not related to winning (for example, a process related to the end control of the big bonus and the deletion of a winning flag that does not carry over) are also performed. Then, the process for one game ends, and the process for the next one game starts.

  Next, the lottery process in step S403 will be described in detail. FIG. 18 is a flowchart showing in detail the lottery process executed by the CPU 111 in step S403. In the lottery process, a random number acquisition process is performed, and a random number generated by the random number generation circuit 115 is output by the sampling circuit 116 by outputting a sampling command, and the extracted random number is processed into a random number for internal lottery. It is stored in a random number storage area for internal lottery (step S501). Details of the random number acquisition process will be described later.

  Next, the set value stored in the set value work 112-4 of the RAM 112 is read (step S502), and it is determined whether or not the read set value is in the range of 1 to 6 that is a value that should be originally taken. (Step S503). If the read set value is not in the range of 1 to 6, a RAM abnormality error occurs, and the RAM abnormality error process shown in FIG. 16 is performed.

  If the read set value is in the range of 1 to 6, the big bonus medium flag or regular bonus medium flag is not set in the RAM 112, and the big bonus winning flag, regular bonus winning flag, and challenge bonus winning flag are also set. Whether or not the current gaming state is the normal gaming state and the bonus winning flag is not carried over is determined according to whether or not there is a CT (step S504). If the bonus winning flag is not carried over in the normal gaming state and is not a CT, the process proceeds to step S515 as it is.

  In the normal gaming state, when the bonus winning flag is not carried over, or in the case of CT, the lottery role corresponding to the gaming state registered in the special role table of FIG. Are read in order (step S505). Next, the number of BETs set in the current game is read, and the setting status of the common flag in the role-specific table of FIG. 6C is acquired corresponding to the number of BETs read for the lottery target (step) S506). As a result, it is determined whether the common flag is set (step S507).

  If the common flag is set, the number of determination values stored in the address registered in the role-specific table of FIG. 6C corresponding to the number of BETs for the lottery target role is acquired (step S508). ). Then, the process proceeds to step S510. If the common flag is not set, the setting value set in the RAM 112 is read out and stored in the address registered in the role-specific table corresponding to the BET number and the read setting value for the lottery target role. The number of determination values that are present is acquired (step S509). Then, the process proceeds to step S510.

  In step S510, the number of determination values acquired in step S508 or S509 is added to the random number value for internal lottery stored in the determination area of the RAM 112, 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 (step S511). If no overflow has occurred, it is determined whether or not there are any special roles that are not yet processed among the special roles that are the lottery targets in the gaming state (step S512). If there is something that has not yet been processed, the process returns to step S505, and the processing is continued with the next lottery target registered in the special combination table as the processing target. If there is no special combination not to be processed, the process proceeds to step S515.

  If it is determined in step S511 that an overflow has occurred, a winning flag (in this case, only one type) for the lottery target is set in the RAM 112 (step S513). Thereafter, whether or not the current gaming state is in CT is determined based on whether or not the challenge bonus flag or the SCT flag is set in the RAM 112 (step S514). If the current gaming state is in CT, the process proceeds to step S515. If the current gaming state is not in CT, the process proceeds to step S524 as it is.

  In step S515, the lottery target combination corresponding to the gaming state registered in the small combination table of FIG. Next, the number of BETs set in the current game is read, and the setting status of the common flag in the role-specific table of FIG. 6C is acquired corresponding to the number of BETs read for the lottery target (step) S516). As a result, it is determined whether the common flag is set (step S517).

  If the common flag is set, the number of determination values stored in the address registered in the role-specific table of FIG. 6C corresponding to the number of BETs for the lottery target role is acquired (step S518). ). Then, the process proceeds to step S520. If the common flag is not set, the setting value set in the RAM 112 is read out and stored in the address registered in the role-specific table corresponding to the BET number and the read setting value for the lottery target role. The number of determination values that are present is acquired (step S519). Then, the process proceeds to step S520.

  In step S520, the number of determination values acquired in step S518 or S519 is added to the random number value for internal lottery stored in the determination area of the RAM 112, 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 (step S521). If no overflow has occurred, it is determined whether or not there is a small combination that is not yet a processing target among lotteries that are to be selected in the gaming state (step S522). If there is something that has not yet been processed, the process returns to step S515, and the processing continues with the next lottery target registered in the small role table as the processing target. If there is no small combination not to be processed, the process proceeds to step S523.

  If it is determined in step S521 that an overflow has occurred, a winning flag for the winning combination is set in the RAM 112. Here, if an overflow occurs when the combination of bell + cherry + replay is used as a lottery target, a bell winning flag, a cherry winning flag, and a replay winning flag are set. If an overflow occurs when Bell + Cherry is used for the lottery, a bell winning flag and a cherry winning flag are set. At this time, if the regular bonus winning flag is also set in step S513, the bell winning flag and the cherry winning flag are also set on top of the regular bonus winning flag. Also, when the big bonus winning flag, regular bonus winning flag or challenge bonus winning flag is carried over from the previous game and set in the RAM 112 in the normal gaming state, when the bell, cherry or replay is selected as a lottery target When an overflow occurs, a bell winning flag, a cherry winning flag or a replay winning flag is set in addition to the big bonus winning flag, regular bonus winning flag or challenge bonus winning flag (step S523). Then, the process proceeds to step S524.

  In step S524, a reel control table corresponding to the setting status of the winning flag in the RAM 112 is selected. Then, the lottery process is terminated, and the process returns to the flowchart of FIG.

  Next, the random number acquisition process in step S501 will be described in detail. FIG. 19 is a flowchart showing in detail the random number acquisition process executed by the CPU 111 in step S501. In the random number acquisition process, first, an interrupt to the CPU 111 is prohibited (step S601). Next, a sampling command is output to the sampling circuit 116, the random number generated by the random number generation circuit 115 is latched, and the value of the latched random number is input from the I / O port 114 and extracted. The random number value extracted from the random number generation circuit 115 is stored in the general-purpose register 111GR (step S602).

  Next, the lower byte value and upper byte value of the random number stored in the general-purpose register 111GR are exchanged with each other (step S603). Next, the value of the random number stored in the general-purpose register 111GR is ANDed with 8080h (step S604). Further, the upper byte (15th to 8th bits) is shifted downward by 1 bit, and 1 is inserted into the empty 15th bit. At this time, the value stored in the general-purpose register 111GR is acquired as a random number for internal lottery and stored in a predetermined area of the RAM 112 (step S605). Then, after permitting the interrupt prohibited in step S601 (step S606), the random number acquisition process is terminated, and the process returns to the flowchart of FIG.

  Next, the reel fluctuation stop process in step S405 will be described in detail. FIG. 20A is a flowchart showing in detail the reel fluctuation stop processing executed by the CPU 111 in step S405. The reel fluctuation stop processing is performed by combining the stop switch 42L, the reel motor 3ML, and the reel sensor 3SL, the combination of the stop switch 42C, the reel motor 3MC, and the reel sensor 3SC, and the stop switch 42R, the reel motor 3MR, and the reel sensor 3SR. It is executed corresponding to the combination.

  First, it is determined whether or not the detection signal of the stop switch 42L, 42C, or 42R has been input by operating the stop button 12L, 12C, or 12R (step S701). Until the detection signal of the stop switch 42L, 42C or 42R is input, the determination as to whether the detection signal is input is repeatedly performed. When the detection signal of the stop switch 42L, 42C or 42R is input, the processing of the next steps S702 to S710 is performed for the reel motor 3ML, 3MC or 3MR corresponding to the detection signal. The description will be continued assuming that the detection signal of the switch 42L is input.

  When the detection signal of the stop switch 42L is input, the value of the counter for counting the number of steps of the reel motor 3ML stored in the RAM 112 is read (step S702). The value of this counter is a value updated by the timer interrupt process of FIG.

  Next, referring to the reel control table selected in step S524 based on the value of the counter read here, the stop step of the reel motor 3ML according to the position where the rotation of the reel 3L is stopped is specified, and temporarily stored in the RAM 112. (Step S703). Here, by designating the stop step with reference to the reel control table, the symbols corresponding to the number of bets and the setting status of the winning flag are stopped on the left reel 3L.

  Next, when stopping the set stop step symbol, it is determined whether it is time to start the stop control of the reel 3L. For example, the stop step symbol has arrived at a position where it can stop at the stop position. It is determined whether or not (step S704). At the time when this determination is made, the excitation phases φ1 to φ4 of the reel motor 3ML are excited by the 1-2 phase excitation method. The process of step S704 is repeatedly executed until it is determined that it is time to start the stop control.

  If it is determined that it is time to start the stop control, it is determined whether or not it is a period in which only one phase is excited among the excitation phases φ1 to φ4 of the reel motor 3ML (step S705). If it is a period during which two phases are excited, the process waits until switching to one-phase excitation. If it is determined that it is the one-phase excitation period, for example, if the excitation phase excited in the one-phase excitation period is φ1, only the excitation phases φ1 and φ2 are excited with the first voltage V1 to “2”. Phase excitation control "is performed (step S706).

  When two-phase excitation control is performed by exciting the excitation phases φ1 and φ2 in this way, the stop phase is φ3 and the brake phases are φ2 and φ4 in the three-phase excitation control described later. To explain. Thereafter, it is determined whether or not the hold time T1 has elapsed since the start of the two-phase excitation control (step S707). If the hold time T1 has not elapsed, the process returns to step S706 and “two-phase excitation control” is continued until the hold time T1 elapses. Thereby, the rotor 3b of the reel motor 3ML is rapidly braked.

  When the hold time T1 has elapsed, in order to start “three-phase excitation control”, for example, φ1 is demagnetized, and the stop phase φ3 and the two brake phases φ2 and φ4 are set to a second voltage higher than the first voltage V1. A process of exciting at V2 is performed (step S708). By performing the three-phase excitation control with the second voltage V2 higher than the first voltage V1, the hold time T2 shown below is shortened in a shorter time than when the three-phase excitation control is performed with the first voltage V1. Thereafter, it is determined whether or not the hold time T2 has elapsed since the start of the three-phase excitation control (step S709). If the hold time T2 has not elapsed, the process returns to step S708 and “three-phase excitation control” is continued until the hold time T2 elapses. Thereby, the rotor 3b of the reel motor 3ML stops at the holding torque stable point of the stop phase φ3.

  When the hold time T2 elapses, the two excitation phases φ1 and φ2 that function as the brake phase are demagnetized, and only the stop phase φ3 is excited by the third voltage V3. As a result, the state in which the rotor 3b of the reel motor 3ML is stopped at the holding torque stable point of the stop phase φ3 is maintained, and the position of the stop step specified in step S703 for the left reel 3L is stopped on the middle effective line. State is maintained. Further, since unnecessary excitation of the brake phases φ2 and φ4 does not continue, heat generation of the reel motor 3ML can be suppressed.

  After only the stop phase φ3 is energized with the third voltage V3, all the reels 3L, 3C, 3R constituting the variable display device 2 are stopped including the reels stopped in steps S702 to S710 this time. It is determined whether or not there is (step S711). If all the reels 3L, 3C, and 3R have not stopped yet, the process returns to step S701 to wait for the input of a stop switch detection signal corresponding to the reel that has not stopped. When all the reels 3L, 3C, 3R are stopped, the reel fluctuation stop processing is ended and the process returns to the flowchart of FIG.

  FIG. 20B is periodically executed by the CPU 111 of the game control board 101 (at least at a time interval shorter than the time for one step when the stepping motor 3M is driven by 1-2 phase excitation). 4 is a flowchart showing a part related to updating of a counter that counts the number of steps of the reel motors 3ML, 3MC, and 3MR in the timer interrupt processing. The counting of the number of steps is executed corresponding to the combination of the reel motor 3ML and the reel sensor 3SL, the combination of the reel motor 3MC and the reel sensor 3SC, and the combination of the reel motor 3MR and the reel sensor 3SR. Here, a case where the counter value is updated in correspondence with the combination of the reel motor 3ML and the reel sensor 3SL will be described as an example.

  First, it is determined whether or not the notch provided as the reference position of the reel 3L has been detected by the reel sensor 3SL (step S751). When the cutout is not detected, the process proceeds to step S753 as it is. When a notch is detected, that is, when no step-out has occurred, the counter value has reached 336, which is the total number of steps of the reel motor 3ML, and therefore the step number corresponding to the step of the reel motor 3ML is specified. The counter value for resetting is reset to 0 (step S752). Then, the process proceeds to step S753.

  In step S753, it is determined whether the excitation state of the excitation phases φ1 to φ4 of the reel motor 3ML has changed from one-phase excitation to two-phase excitation, or has changed from two-phase excitation to one-phase excitation. For this determination, the state of the excitation states φ1 to φ4 of the excitation phase of the reel motor 3ML is stored in the RAM 112. If it is determined that the state has changed since the previous determination, the stored contents are updated. It is supposed to be. When the excitation state has not changed, the timer interrupt process is terminated without updating the counter value. When the excitation state is changing, the counter value is incremented by 1 (step S754), and the timer interrupt process is terminated.

  In the repetition of the game as described above, the CPU 111 of the game control board 101 shifts the game state between the normal game state, the regular bonus, the big bonus, and the CT, and issues a command according to the progress of the game. It is transmitted to the production control board 102. On the other hand, the CPU 121 of the effect control board 102 performs an original effect based on the command received from the game control board 101. The effect when receiving a command from the game control board 101 is not directly related to the present invention, and thus the description thereof is omitted.

  As described above, in the slot machine 1 according to this embodiment, when the gaming state is CT, the winning flag of at least the small role bell and cherry is set in the RAM 112 according to the result of the internal lottery. . In CT, the maximum stop delay time of the right reel 3R is shortened from the usual 190 milliseconds to 75 milliseconds, and the number of drawn frames is reduced from 4 frames to 1 frame, so it is useful in accordance with the set winning flag. It becomes difficult to operate the stop button 12R at an appropriate timing when a winning is possible. However, as long as the operation of the stop button 12R is appropriate, the medal can be paid out by the small role winning. Increasing the player's technical intervention in this way increases the gameability.

  Further, in the reel control table selected when the gaming state is CT and the bell winning flag and the cherry winning flag are set, the control for stopping the “cherry” symbol at the upper or lower stage for the left reel 3L. Will be won, not the bell from which 8 medals are obtained, but the bell from which 15 medals are obtained. In this way, winning of a combination with a large number of medals to be paid out is given priority, so that a player cannot receive a sufficient profit by receiving only a small number of medals.

  Of course, when the left reel 3L is the third reel, the symbol “bell” is displayed as much as possible as the display mode of the middle and right reels 3C and 3R serving as the first and second reels. It will be a thing. Therefore, before the left reel 3L, which is the third reel, stops, the player will not lose the profit for the winning of the bell.

  However, the control content for making the “bell” symbol on the middle and right reels 3 </ b> C and 3 </ b> R is written on the condition that it is not a prohibited item as shown in FIG. If the prohibition is led to the middle and right reels 3C and 3R, depending on the design displayed on the left reel 3L when the operation of the stop button 12L is detected, the upper or lower stage of the left reel 3L may be When “Cherry” is derived, the CT symbol combination is also derived at the same time. Here, since the control of the second reel is performed avoiding the derivation of the forbidden eyes, there is no inconvenience that the symbol combination that cannot be derived at the time of CT is derived. Also, in order to avoid symbol combinations that cannot be derived at the time of CT, the player will not lose the prize for the cherry that can obtain the most profits, so there is no loss to the player.

  By the way, when the gaming state is CT, the maximum stop delay time of the right reel 3R is shortened to 75 milliseconds, so that even a player with a low skill level can set the replay winning flag. In some cases, a replay prize cannot be awarded, and the amount of medals consumed increases by setting the number of bets. On the other hand, even if the replay winning flag is set in CT, even if the replay winning is impossible, there is a case where a small role is won, so the amount of medals reduced for setting the bet number is reduced. It can be recovered by winning a prize. As a result, even a player with a low skill level can sufficiently secure a profit in CT.

  As described above, the types of the roles that are subject to the internal lottery for each gaming state are registered in the lottery target table for each gaming state, but the number of judgment values that determine the winning probability of each role is referred from the table for each role. Is stored at the address. In the role-specific table, for the bells and cherries that can win according to the result of the internal lottery other than CT, the storage address of the judgment value number is registered for each bet number, and the judgment value number is acquired according to the bet number Will be. Here, the number of bets in the regular bonus and CT is fixed at 1, but the number of bets in the gaming state other than the regular bonus and CT is fixed at 3.

  As a result, it is possible to perform the internal lottery of the bell and the cherry with the winning probability corresponding to the gaming state only by acquiring the determination value number according to the betting number. 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. Moreover, the betting number 1 corresponding to the regular bonus has a higher probability of winning the bell than when the betting number is 3, so that the player's expectation in the regular bonus is further increased and the interest of the game is improved. Can do.

  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 number of bets set 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 for 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 determination value number is stored in the ROM 113 by 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. It should be noted that when the winning determination table is generated before the actual winning determination is made, the loop processing is required twice, but according to this embodiment, the loop processing in the lottery processing is only required once. Thus, the processing efficiency in the entire lottery process is high.

  By the way, in the slot machine 1 according to this embodiment, when the number of determination values corresponding to the combination to be selected for the lottery is sequentially added to the random number for the internal lottery according to the gaming state, and the result of the addition overflows It is determined that the winning combination has been won. When the internal lottery is performed in this way, the processing efficiency is high, but the determination value as to whether or not each winning combination is won is determined and determined for each winning combination.

  However, 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 115 by the sampling circuit 116 but is used after being processed by software. The random number generation circuit 115 generates a random number by updating at a high speed with the frequency of the pulse signal of the pulse generation circuit 115a. However, in the random number for internal lottery processed by software, the periodicity of the update is increased by the processing. It will be lost. Thereby, it is possible to prevent the player from hitting as much as possible by losing the periodicity of the random numbers for internal lottery and varying the values.

  Moreover, the frequency of the pulse signal generated by the pulse generation circuit 115a to update the values of the counters 115b and 115c of the random number generation circuit 115 is higher than the frequency of the operation clock of the CPU 111, and is not an integral multiple. For this reason, the update of the random number generated by the random number generation circuit 115 becomes difficult to synchronize with the processing performed by the CPU 111. In addition, by increasing the frequency of the pulse signal of the pulse generation circuit 115a, the update speed of the random number generated by the random number generation circuit 115 can be made extremely fast. For this reason, the effect of preventing aiming by the player is further enhanced.

  On the other hand, the processing of random numbers by software is performed by replacing the upper byte and lower byte of the random number extracted from the random number generation circuit 115 by the sampling circuit 116, masking the 15th and 7th bits, and then bit-shifting the upper byte. Good. Therefore, even for a relatively large random number of 16 bits (actually masked 14 bits), the load required for processing necessary to lose periodicity is not so large, and can be easily obtained. Can do. Since a large random number can be acquired in this way, the probability setting in the internal lottery can be finely performed.

  Further, in the slot machine 1 according to this embodiment, when an abnormality occurs in the data stored in the RAM 112, the RAM is controlled to an abnormal error state of the RAM, the progress of the game is disabled, and the setting change mode is set. If the setting value is not newly selected / set based on the setting change operation, the game disabled state is not released. That is, even if an abnormality occurs in the data stored in the RAM 112, the setting value selected and set based on the setting change operation (in general, the setting value) is not set automatically by the slot machine 1. Since the change operation is performed by an employee of the game shop, it is ensured that the game is played based on the setting value selected by the game shop), so that the game can be fair.

  In addition, when determining whether or not to win the winning combination in the internal lottery, the set value stored in the set value work 112-4 must be an appropriate value (a value in the range of 1 to 6). For example, instead of deciding whether or not to win based on a probability based on a default setting value (for example, setting 1), in this case as well, the game is controlled to a RAM abnormal error state and the progress of the game is disabled. If the setting change mode is entered and a new setting value is not selected or set based on the setting change operation, the state where the progress of the game is disabled is not released. In other words, even when it is not possible to properly determine whether or not to win the winning combination in the internal lottery, the game may be played based on the setting value selected and set based on the setting change operation. Since it is secured, the fairness of the game can be achieved.

  Further, the data stored in the RAM 112 is abnormal in most cases when the control cannot be continued due to a malfunction in the control such as a power failure or the control unit 110 running away. Since it is determined whether or not the data is normal only when the control unit 110 is activated after recovering from these states, the determination whether or not the data stored in the RAM 112 is normal is abnormal. Can only be done in situations where there is a high probability that That is, in a situation where there is a low possibility that an abnormality has occurred in the data stored in the RAM 112, it is not necessary to perform the determination, and the load on the control unit 110 can be reduced.

  In particular, in the power interruption interrupt process executed by the input of the voltage drop signal generated when the power is cut off, the RAM parity is calculated based on the data stored in the RAM 112 and stored in the parity storage area 112-7. At the next startup, the RAM parity obtained by the calculation is compared with the RAM parity stored in the parity storage area 112-7 to determine whether the data in the RAM 112 is normal. is doing. In this way, it is possible to determine whether or not the data in the RAM 112 is normal only by comparing the RAM parity at the time of input of the voltage drop signal generated when the power is shut off and at the time of startup, so that the determination is performed accurately and simply. Can do.

  In addition, when an abnormality occurs in the data of the RAM 112 and the progress of the game is disabled, a setting change mode in which a setting value changing operation that becomes a condition for releasing the disabled state of the game is enabled Along with the transition to (setting change process), the data stored in the RAM 112 is initialized. For this reason, the initialization of data associated with the occurrence of an abnormality in the data in the RAM 112 and the initialization of data associated with selection / setting of the set value can be performed at one time, so that useless processing can be omitted. .

  Further, when the rotation of the reels 3L, 3C, 3R is stopped, the first voltage V1 is applied to the stepping motor 3M (reel motors 3ML, 3MC, 3MR) to perform two-phase excitation control, and then the first voltage is applied. Higher second voltage V2 is applied to the stepping motor 3M to perform three-phase excitation control. As a result, the time for performing the three-phase excitation control can be shortened to suppress the vibration when the reels 3L, 3C, and 3R are stopped, and the accuracy of the stop control of the reels 3L, 3C, and 3R can be improved.

  Further, when the control unit 110 is activated, it is determined whether or not the setting key switch 92 is ON before determining whether or not the data in the RAM 112 is normal. At that time, the setting key switch 92 is If it is determined that the data is in the ON state, the process proceeds to the setting change mode without determining whether the data in the RAM 112 is normal. In this way, a new set value is selected and set without determining whether or not the data in the RAM 112 is normal, so that useless processing can be omitted.

  The present invention is not limited to the above-described embodiment, and various modifications and applications are possible. Hereinafter, modifications of the above-described embodiment applicable to the present invention will be described.

  In the above embodiment, in the gaming state of CT, if the bell + cherry + replay is won, the bell winning flag and the cherry winning flag are set in the RAM 112. If the bell + cherry is won, the bell winning flag and the cherry winning flag are set in the RAM 112. I was supposed to. On the other hand, the winning flag set in this case may be a common winning flag common to the bell and the cherry. When the common winning flag is set in the RAM 112, either the bell or the cherry can be won. It may be a thing. In the CT gaming state, no matter what the result of the internal lottery is, the bell and the cherry can be won, so the challenge bonus flag or the SCT flag is set as the bell winning flag and the cherry winning flag, Alternatively, it may be applied as a substitute for the common winning flag, and the bell winning flag and the cherry winning flag or the common winning flag may not be set again according to the lottery result.

  In the above embodiment, in the CT gaming state, only the right reel 3R is shortened to a maximum stop delay time of 75 milliseconds, and the maximum stop delay time for the left reel 3L and the middle reel 3C is the normal case. The same 190 ms. However, the reel whose maximum stop delay time is shortened in CT is not limited to the right reel 3R, but may be the left reel 3L or the inner reel 3C. For two or all of the reels 3L, 3C, and 3R, the maximum stop delay time may be shortened to 75 milliseconds in CT.

  In the above embodiment, “cherry” is arranged at intervals of 7 frames in the left reel 3L, and the maximum stop delay time of the left reel 3L is not shortened in CT, so regardless of the operation timing of the stop button 12L. The “cherry” must be stopped at the upper or lower stage to obtain 15 payouts. On the other hand, when the arrangement interval of “cherry” is 8 frames or more or the maximum stop delay time of the left reel 3L is shortened to 75 milliseconds, depending on the operation timing of the stop button 12L, In some cases, “cherry” cannot be stopped at the upper or lower stage of the left reel 3L.

  Even in such a case, when the inner reel 3C and the right reel 3R are stopped as the first and second reels, the maximum stop delay time is 190 milliseconds and 75 milliseconds, respectively. If the “bell” can be tempered, the “bell” can be tempered by pulling it. Thus, depending on the operation timing of the stop button 12L corresponding to the left reel 3L as the third reel, the cherry may not be won, but even in this case, eight payouts can be received by winning the bell. It is possible to give the player as much profit as possible until the rotation of all the reels 3L, 3C, 3R is finally stopped.

  In addition, when the left reel 3L is stopped as the first, even if the “cherry” cannot be stopped at the upper stage or the lower stage, the “bell” can be stopped at either the upper, middle, or lower stage. Stop this. Thereafter, if the “bell” can be tempered when the second reel is stopped, the “bell” can be tempered. When the left reel 3L is stopped as the third reel, the “bell” is stopped at one of the upper, middle and lower stages of the first reel, and the “bell” may be stopped on the same effective line. If possible, stop this. As a result, even if the winning of the cherry becomes impossible due to the operation timing of the stop button 12L corresponding to the left reel 3L, the possibility of winning the bell can be continued as much as possible, and the profit as much as possible can be obtained. Can be given to players.

  In addition, in such a symbol arrangement, a reel control table in which control details for stopping the rotation of the reels 3L, 3C, and 3R are prepared, and a bell winning flag and a cherry winning flag are set in CT. Should be selected when

  In the above-described embodiment, if “cherry” stops at the upper or lower stage of the left reel 3L, a cherry prize is awarded on the three effective lines and 15 medals are paid out. On the other hand, the small combination that can obtain the maximum payout in one game may be one in which three symbols are aligned on the active line as in the bell in the above embodiment and become a prize. When the symbol combination of winning combinations is determined in this way, in the CT gaming state, the maximum stop delay time determined for the first and second reels is set before the third reel is stopped. If a small combination with a large payout within the range can be tempered, the first and second reels may be controlled to stop when a small combination with a small payout is tempered.

  Depending on the arrangement of the symbols on the first and second reels, the maximum stop set for the first and second reels can be used if both the small payout and the small payout that can be paid out can be double-tempered. It is possible to double-temper as much as possible within the range of the delay time. Here, only when there is a possibility that a display result that cannot be derived during CT when the third reel is stopped can be unavoidable by double-tempering both small payouts and small payouts. If only a small combination with many payouts is made into a temper and it becomes possible to win the small combination regardless of the stop timing of the third reel, the shape of the double tempe is broken and the first and second reels are controlled to stop. do it.

  In the above embodiment, the entire high-order byte of the random number extracted from the random number generation circuit 115 is replaced with the low-order byte, and the whole low-order byte is replaced with the high-order byte. On the other hand, the data of a specific bit among the random number bits extracted from the random number generation circuit 115 is simply replaced with data of other bits (however, other than the masked seventh and fifteenth bits). Also good. Alternatively, the random number value extracted from the random number generation circuit 115 may be directly acquired as a random number for internal lottery. Furthermore, it may be processed into a random number for internal lottery by a method different from the above embodiment.

  FIG. 21 is an explanatory diagram of a first modification of the process (step S501) until the CPU 111 processes the random number extracted from the random number generation circuit 115 into a random number for internal lottery by software. Also in the first modification, the random number extracted from the random number generation circuit 115 is stored in the 16-bit general-purpose register 111GR included in the CPU 111.

  When the random number extracted from the random number generation circuit 115 is stored in the general-purpose register 111GR, the CPU 111 further extracts the value of the internal refresh register 111R as a processing random number. The CPU 111 adds the processing random number extracted from the refresh register 111R to the value of the upper byte of the general-purpose register 111GR (the value extracted from the upper counter 115c). The lower byte value of the general register 111GR (the value extracted from the lower counter 115b) is left as it is.

  Next, the CPU 111 performs an AND operation on the value of the general-purpose register 111GR, that is, a value obtained by adding a processing random number to the upper byte and 8080h. Further, the CPU 111 shifts the upper 1 byte (8th bit to 15th bit) to the lower bit by bit, and inserts 1 into the empty 15th bit. The CPU 111 acquires the value stored in the general-purpose register 111GR at this time as a random number for internal lottery, and sequentially adds the number of determination values to this.

  FIG. 22 is an explanatory diagram of a second modification of the process (step S501) until the CPU 111 processes the random number extracted from the random number generation circuit 115 into a random number for internal lottery by software. Also in this example, the random number extracted from the random number generation circuit 115 is stored in the 16-bit general-purpose register 111GR included in the CPU 111.

  When the random number extracted from the random number generation circuit 115 is stored in the general-purpose register 111GR, the CPU 111 further extracts the value of the internal refresh register 111R as a processing random number. The CPU 111 adds the processing random number extracted from the refresh register 111R to the value of the upper byte of the general-purpose register 111GR (the value extracted from the upper counter 115c). The processing random number extracted from the refresh register 111R is also added to the lower byte value (the value extracted from the lower counter 115b) of the general-purpose register 111GR.

  Next, the CPU 111 performs an AND operation on the value of the general-purpose register 111GR, that is, a value obtained by adding a processing random number to the upper byte and the lower byte, respectively, with 8080h. Further, the CPU 111 shifts the upper 1 byte (8th bit to 15th bit) to the lower bit by bit, and inserts 1 into the empty 15th bit. The CPU 111 acquires the value stored in the general-purpose register 111GR at this time as a random number for internal lottery, and sequentially adds the number of determination values to this.

  In the first and second modified examples described above, the value of the refresh register 111R 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 115 (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 111R, no special configuration is required as means for generating the processing random numbers. Moreover, since the value of the refresh register 111R is updated every time the CPU 111 fetches an instruction, and the update interval is not constant, 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 modified examples, the value extracted from the refresh register 111R is added to the upper byte (and the lower byte) of the random number extracted from the random number generation circuit 115. A value that is periodically updated by hardware or software may be added. Further, instead of adding a value extracted from the refresh register 111R (or a value replacing the refresh register 111R), 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, during the period from the extraction of the random number from the random number generation circuit 115 to the end of processing, the interrupt to the CPU 111 is prevented in order to prevent the contents of the general-purpose register 111GR from being rewritten. 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 115 may be separately extracted from the refresh register 111R 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 configured by the refresh register 111R.

  In both the above embodiment and the first and second modifications, the seventh and fifteenth bits are masked to generate a random number for internal lottery. That is, the random number value for internal lottery is represented by 14 bits and takes a range of 0 to 16383. However, the value represented by 16 bits can be directly applied as a random number for internal lottery without masking the 7th and 15th bits. In this case, the number of determination values for each target part of the internal lottery may be registered in the ROM 113 according to the range of values that the random numbers for internal lottery can take.

  On the other hand, if the random numbers for internal lottery are generated by masking the seventh and fifteenth bits as in the above embodiment and the first and second modifications, the masked two bits Can be applied as a random number for making a decision different from the internal lottery (for example, selection of the type of effect). Thereby, all the bits of the random number extracted from the random number generation circuit 115 can be used effectively.

  FIG. 23 is an explanatory diagram of a third modification of the process (step S501) until the CPU 111 processes the random number extracted from the random number generation circuit 115 into a random number for internal lottery by software. In this example, the signal wirings connecting the random number generation circuit 115 and the sampling circuit 116 are connected so that the order of bits is reversed for each of the upper 8 bits and the lower 8 bits. Accordingly, the data latched by the sampling circuit 116 is reverse in the order of bit arrangement for the upper 8 bits and the lower 8 bits with respect to the data signal output by the random number generation circuit 115.

  The CPU 111 fetches numerical data corresponding to the data signal input from the sampling circuit 116 via the I / O port 114 from the sampling circuit 116 separately from the upper 8 bits and the lower 8 bits, and is provided in the RAM 112. Temporarily stored in the random number storage area for internal lottery. The random number storage area for internal lottery is provided for 2 bytes. The upper byte storage area is called the upper area, and the lower byte storage area is called the lower area.

  When the CPU 111 fetches numerical data from the sampling circuit 116, the upper 8 bits of the random number latched by the sampling circuit 116 is taken into the lower area, and the lower 8 bits of the latched random number are taken into the upper area. Therefore, the numerical data taken by the CPU 111 from the sampling circuit 116 into the internal lottery random number storage area is completely in reverse order to the data signal generated by the random number generation circuit 115.

  For the random number latched by the sampling circuit 116 or the random number processed by the CPU 111, the least significant bit is called the 0th bit and the most significant bit is called the 7th bit for each upper byte and lower byte. The data signal output from the random number generation circuit 115 is described as a random number corresponding to the logical value, and the numerical data latched by the sampling circuit 116 is also described as a random number corresponding to the value.

  As described above, when the random number generated by the random number generation circuit 115 is latched by the sampling circuit 116, the bit order of the latched random numbers is reversed for the upper 8 bits and the lower 8 bits ((a) To (b)). The CPU 111 captures the upper 8 bits of the random number latched by the sampling circuit 116 from the upper port into the lower area of the RAM 112 and the lower 8 bits from the lower port into the upper area of the RAM 112 ((b) to (d)). Thus, 16-bit numerical data composed of numerical data taken into the upper area and lower area of the RAM 112 is a random number before processing.

  The data in the lower area is rewritten by the subsequent processing. However, since the data in the lower area of the random number before the processing may be used after that, the data in the lower area before the processing is used as the save data. Save in the save area. Next, the CPU 111 subtracts 11h from the upper area data, and temporarily stores the resulting data in the upper area (e). Next, data in the upper area is read, the data is rotated bit by bit to the lower (right), and the resulting data is temporarily stored in the upper area (f).

  Next, an exclusive OR operation is performed on the upper area data and the lower area data bit by bit, and the resulting data is newly stored in both the upper area and the lower area (g). Further, the saving area data 78h is added, and the resulting data is temporarily stored in the saving area (h). Then, an exclusive OR operation is performed on the upper area data and the save area data for each bit, and the resulting data is newly stored in the upper area (i). At this time, numerical data in which the data stored in the upper area is the upper 8 bits and the data stored in the lower area is the lower 8 bits is acquired as a random number for internal lottery (j).

  Here, the random number for internal lottery finally generated here appears almost randomly every time a pulse signal is input. That is, both continuity and periodicity are eliminated. Here, it is assumed that a state in which values are completely continuous, such as the numerical value of the random number generation circuit 115, approaches a state in which discontinuous values appear randomly. For example, any one of the change from the numerical value of the random number generation circuit 115 to the numerical value of the sampling circuit 116, the change from the numerical value of the sampling circuit 116 to the random number before processing, and the change from the random number before processing to the random number for internal lottery. Corresponds to those whose values vary. The same is true for variations and variations.

  In this third modification, 11h is subtracted from the upper area data before the final exclusive OR operation (FIG. 23 (i)) of the upper area data and the lower area data (FIG. 23). 23 (e)), rotate 1 bit lower (FIG. 23 (f)), perform exclusive OR operation with lower area data (FIG. 23 (g)), and process upper area data in advance. However, not all of these are necessarily required, and any one or two of them can be applied, and there is no need to process the data in the upper area before the final exclusive OR operation. Good. The upper area data at this time may be the final upper byte data in the random number for internal lottery. The order in which the processes of FIGS. 23E to 23F are performed can be changed to an arbitrary order.

  Also, the value to be subtracted in FIG. 23 (e) is not limited to 11h, and any value other than 00h can be added or subtracted, and the rotation in FIG. 23 (f) is limited to 1 bit in the lower order. It can be rotated up or down by any number of bits up to 7 bits. In FIG. 23 (g), the data in the lower region subjected to the exclusive OR operation may be obtained by performing a predetermined operation on the data first input to the lower region from the random number generation circuit 115. As a calculation performed on the data in the upper area, a calculation by an arithmetic expression other than this can be applied. Furthermore, the data in the save area that is subjected to an exclusive OR operation on the data in the upper area in FIG. 23 (i) may be data that is first input to the lower area from the random number generation circuit 115. FIG. Data obtained by performing a predetermined calculation different from (e) to (g) may be used.

  Further, the final lower byte data in the random numbers for internal lottery may be the data that is first input from the random number generation circuit 115 to the lower area as it is. The data in the save area after adding 78h in FIG. 23 (h) may be the final lower byte data in the random number for internal lottery. Alternatively, 78h may be added to the data of the result of the exclusive OR operation stored in the lower area in FIG. 23G to obtain the final lower byte data. Furthermore, as a calculation to be performed on the data in the lower area, a calculation based on another calculation formula may be applied, and the calculation result may be the final lower byte data in the random number for internal lottery.

  When the instruction set of the CPU 111 is the 2-address system or the 3-address system, 11h is subtracted from the data stored in the upper area of the RAM 112, and the data of the subtraction result is stored in the upper area. The data stored in the upper area of the RAM 112 and the data stored in the lower area of the RAM 112 are exclusive ORed, and the data of the result of the exclusive OR operation is stored in the upper area. be able to.

  On the other hand, when the instruction set of the CPU 111 is the one-address method, for example, when subtraction as shown in FIG. 23 (e) is performed, the data stored in the upper area of the RAM 112 is first stored in an accumulator (general register). ), 11h is subtracted from the accumulator data, and the subtraction result data is stored again in the accumulator. Here, when the data stored in the upper area of the RAM 112 is loaded into the accumulator, the accumulator effectively acts as the upper area. Here, the accumulator still operates on the data in the upper area. It is not necessary to store the data in the upper area of the RAM 112 yet.

  In FIG. 23 (f), the accumulator data in which the result of the subtraction in FIG. 23 (e) is stored is rotated to the lower bit by bit, and the resulting data is stored again in the accumulator. In FIG. 23 (g), an exclusive OR operation is performed on the data stored in the lower area of the RAM 112 for each bit with respect to the accumulator data in which the result of the operation in FIG. 23 (f) is stored. Is stored in the accumulator. At this point, since the accumulator is still functioning as the upper area of the RAM 112, the accumulator data may be stored in the lower area of the RAM 112 in FIG. 23 (g) → (j).

  Further, in FIG. 23 (h), the data in the save area of the RAM 112 is loaded into the accumulator, but the accumulator functions as the save area here, and 11h is added to the accumulator data and stored in the accumulator. In FIG. 23 (i), the data of the accumulator is exclusive ORed with the data in the upper area of the RAM 112 for each bit, and the result is stored in the accumulator, but the result of the exclusive OR operation is stored. After that, the accumulator again acts as the upper region.

  Thus, the accumulator in the CPU 111 having a one-address instruction set acts as any of the upper area, the lower area, and the save area depending on the data stored in the calculation process (although as described above) In the random number processing method, the accumulator does not act as a lower region). Similarly, the stack in the CPU 111 having the instruction address t of the 0 address system also functions as any of the upper area, the lower area, and the save area depending on the data stored in the calculation process.

  Further, if the CPU 111 has a plurality of general-purpose registers, the RAM 112 may not be provided with an upper area and a lower area, but any two general-purpose registers may be applied as the upper area and the lower area. In particular, if the CPU 111 has a 2-byte general-purpose register in addition to the 1-byte general-purpose register, it may be used for the upper area and the lower area.

  In the RAM 112, the same upper area and lower area are used both for the area for storing the 2n-bit numerical data fetched from the sampling circuit 116 and for the area for storing the finally generated random numbers for internal lottery. However, separate areas may be used. For example, if a 2-byte random number area that stores the finally generated random numbers for internal lottery is provided separately from the upper and lower areas, the upper area data is stored in the lower bytes of the random area. Then, the result data of the exclusive OR operation of FIG. 23 (i) may be stored in the upper byte of the random number area.

  In the third modified example, the number of random numbers for internal lottery is 16 bits which is the same as the number of random numbers generated by the random number generation circuit 115 and takes a value of 0 to 65535. . In this case, the number of determination values for each combination may be a value corresponding to the size of the random number (for example, four times that in the above embodiment). Simultaneously with the generation of the random number in the above embodiment, a part of the 16 bits (in the above embodiment, the 7th bit and the 15th bit) are thinned, so that a random number for internal lottery can be obtained. The range of possible values may be smaller than this. The thinned 2-bit numerical value can be used for lottery of other processes (for example, effects for bonus notification). Thereby, the thinned bit value can also be used effectively.

  The method of generating random numbers for internal lottery in the third modification can change the processes in FIGS. 23A to 23D as shown in FIGS.

  In the example of FIG. 24, the random number generated by the random number generation circuit 115 is replaced with the upper 8 bits and the lower 8 bits in the same manner as in FIGS. (A) to (b). Next, the upper 8 bits of the random number taken by the sampling circuit 116 are taken into the upper area of the RAM 112 via the upper port, and the lower 8 bits are taken into the lower area of the RAM 112 via the lower port (b) to (d). Thereafter, the numerical data stored in the upper byte and the numerical data stored in the lower byte may be exchanged by software processing to obtain a random number before processing (e).

  Note that the connection order of the wiring between the random number generation circuit 115 and the sampling circuit 116 is reversed, and the arrangement order of the upper byte and the lower byte is not reversed for the random number that is first fetched into the RAM 112. The connection order of the wiring between the circuit 116 and the upper port: lower port is reversed, and the arrangement order of the upper byte and the lower byte of the random number that is first fetched into the RAM 112 is changed to the random number generated by the random number generation circuit 115. The order may be reversed. This point can also be applied to the example of FIG.

  In the example of FIG. 25, the connection of wiring between the random number generation circuit 115 and the sampling circuit 116 is not reversed. First, the random numbers generated by the random number generation circuit 115 are sampled in the order of the bits as they are. (A) to (b). Next, the upper 8 bits of the random number taken by the sampling circuit 116 are taken into the upper area of the RAM 112 via the upper port, and the lower 8 bits are taken into the lower area of the RAM 112 via the lower port (b) to (d).

  Thereafter, the numerical data stored in the upper byte and the numerical data stored in the lower byte are switched by software processing (e). Furthermore, the random number before processing may be obtained by switching the bit arrangement order of the numerical data stored in the upper byte and the numerical data stored in the lower byte in reverse order by software processing (f). Note that the numerical data stored in the upper byte and the numerical data stored in the lower byte are first changed to reverse the bit order of the numerical data stored in the upper byte and the numerical data stored in the lower byte. May be replaced later.

  In the example of FIG. 26, the wiring between the random number generation circuit 115 and the sampling circuit 116 is reversed between the upper byte and the lower byte, and is connected so that the bit order is not changed in each byte. . Here, the random number generated by the random number generation circuit 115 is taken into the sampling circuit by switching the upper byte and the lower byte (a) to (b). Next, the upper 8 bits of the random number taken by the sampling circuit 116 are taken into the upper area of the RAM 112 via the upper port, and the lower 8 bits are taken into the lower area of the RAM 112 via the lower port (b) to (d).

  Thereafter, the bit order of the numerical data stored in the upper byte and the numerical data stored in the lower byte may be reversed in a software process to obtain a random number before processing (e). Note that the arrangement order of the wiring between the random number generation circuit 115 and the sampling circuit 116 is not changed, and the upper byte of the sampling circuit 116 may be connected to the lower port of the CPU 111 and the lower byte may be connected to the upper port. .

  In the example of FIG. 27, the wiring between the random number generation circuit 115 and the sampling circuit 116 is completely connected in reverse order. Here, the sampling circuit 116 takes in the order of the random number bits generated by the random number generation circuit 115 in the reverse order (a) to (b). Then, the upper byte and lower byte of the random number fetched by the sampling circuit 116 may be fetched as they are into the upper area and lower area of the RAM 112 via the upper port and lower port as they are (b) to (d).

  In addition, the order of bits in each byte in the upper byte and lower byte of the random number for internal lottery in the third modification is not necessarily limited to the reverse order. For example, the highest order in each byte The bit and the least significant bit may be simply exchanged. However, in particular, it is preferable that as many bits as possible be replaced in the upper byte of the random number generated by the random number generation circuit 115 with a small change in value according to the difference in timing.

  In the above embodiment, the number of determination values is stored in common for all of the setting values 1 to 6 or individually stored for each of the setting values 1 to 6. 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.

  In the above embodiment, in the normal gaming state, the game can be started only by setting 3 as the bet number. On the other hand, even in a normal gaming state, the game can be started by setting 1 as the number of bets, and can be started by setting 2 as the number of bets. May be. In this case, the number of determination values may include not only the combination that is stored in common for all of the setting values 1 to 6 but also the combination that is stored in common for all of the betting numbers 1 to 3. . In this case, the storage area for the number of determination values can be reduced according to the number of bets, and the storage capacity can be further reduced.

  In the above embodiment, the RAM parity at power-off and the RAM parity at startup are compared to determine whether or not the data stored in the RAM 112 is normal. It may be determined whether or not the data is normal. For example, when a voltage drop signal is input due to power-off or the like, a checksum of the data in the RAM 112 (the sum total of the data strings) is created and the checksum area (area corresponding to the parity area 112-7) is created. At the same time as storing, a checksum of data in the RAM 112 may be created and compared with the checksum stored in the checksum area to determine whether or not the data in the RAM 112 is normal. In addition, a cyclic code such as CRC may be used.

  In the above embodiment, the RAM 112 is initialized before shifting to the setting change process. However, the RAM 112 may be initialized in accordance with the shift to the setting changing process. For example, the setting changing process is performed. It may be performed after the end of the process, or may be performed when the set value is confirmed in the setting change process.

  In the above embodiment, when the gaming state is the big bonus, the regular bonus is repeatedly provided, and the gaming state in the big bonus is always the regular bonus. However, the condition for controlling the gaming state in the big bonus to the regular bonus is not limited to this. For example, on the condition that a predetermined result (JACIN) is derived as the display result of the variable display device 2 in the big bonus, It is good also as what controls to a regular bonus. In this case, when the gaming state is controlled to the big bonus, JACIN is also selected as a lottery target in the internal lottery, and when JACIN is won, the JACIN winning flag may be set in the RAM 112. JACIN winning is subject to the setting of the JACIN winning flag.

  In the above embodiment, as the control contents of the reel control table, the symbol of the symbol to be stopped with respect to the step numbers of the reels 3L, 3C, and 3R positioned in the middle when the stop buttons 12L, 12C, and 12R are operated. The stop step number was to be registered. Of course, not the (stop) step number but the symbol number may be registered in the reel control table. The number of sliding symbols up to the symbol to be stopped is registered for the step number (or symbol number) of the reels 3L, 3C, 3R located in the middle when the stop buttons 12L, 12C, 12R are operated. It is good. For example, when the symbol number of the symbol located in the middle stage during the stop operation is 1 and the symbol number of the symbol to be stopped is 3, the number of sliding symbols to be registered is 2. Further, the control contents of the reel control table may be registered with reference to an arbitrary position (for example, the center position of the upper stage or the lower stage) instead of registering the control contents of the reel control table with the middle stage as a reference.

  In the above embodiment, the reel control table is selected in advance based on the setting status of the winning flag, the stop position of the symbol is determined with reference to the reel control table when the reels 3L, 3C, 3R are stopped, and the stop The slot machine that stops the rotation of the reels 3L, 3C, and 3R by the table system that stops the reel at the position has been described as an example. In contrast, based on the current symbol position when the stop condition is satisfied and the setting status of the winning flag, pull-in control is performed so that the symbol of the winning symbol is aligned, or the symbol of the symbol that is not winning The present invention can also be applied to a slot machine that stops the rotation of the reels 3L, 3C, and 3R by a control method in which the removal control is performed so as not to align.

  In the control method, when the operation of the stop buttons 12L, 12C, 12R is detected, the corresponding reels 3L, 3C, 3R are within the range of the maximum stop delay time of 190 milliseconds from the symbol displayed at that time ( It is determined whether or not there is a winning symbol having a winning flag set in a range of a total of five frames including the displayed symbol and the amount drawn. If there is a symbol for a role with a winning flag set (determined from the symbol of the role that is given priority for derivation in the case of duplicate winning), select the symbol for winning the winning combination and select the active line (already stopped) When there is a reel, the winning display mode can be derived together with the symbols on the reels that are stopped. Otherwise, a symbol for not winning any combination is selected and derived. That is, even when the stop of the reels 3L, 3C, 3R is controlled by this control method, it can be derived by stopping the symbols within the range of the maximum stop delay time after the operation of the stop buttons 12L, 12C, 12R is detected. The display mode corresponding to the setting status of the winning flag is derived as the display result of the variable display device 2.

  In the slot machine that stops the rotation of the reels 3L, 3C, and 3R by the control method, the CPU 111 of the game control board 101 sets the right and middle reels 3C and 3R to the first and first when the replay is not won in CT. In the case of two reels, it is determined whether or not the “bell” is tempered when the second reel is stopped, which results in the prohibition eye shown in FIG. Here, if it is determined that it is not prohibited, the “reel” can be tempered to stop the inner reel 3C or the right reel 3R that has become the second reel. On the other hand, if it is determined that the item is prohibited, the inner reel 3C or the right reel 3R that has become the second reel is displayed so that the display mode other than the prohibited item is displayed even if the “bell” is not tempered. It can be stopped.

  In the above embodiment, the variable display device 2 includes the three reels 3L, 3C, and 3R in which a plurality of symbols are arranged in a predetermined order on the outer periphery, and the symbols are driven by rotational driving of these reels 3L, 3C, and 3R. Was variably displayed. However, a device that virtually displays a symbol on a display device such as a liquid crystal display device may be used instead of the variable display device 2 described above.

  In the above-described embodiment, the slot machine to which medals are applied as a game medium used for setting a bet number or giving a valuable value associated with winning has been described as an example. However, the slot machine embodying the present invention may be a slot machine (so-called parrot) to which a game ball used in a pachinko gaming machine is applied as a game medium. When game balls are used as game media, one medal can correspond to five game balls. For example, when 3 is set as the bet number in the above embodiment, 15 game balls are used. This is equivalent to setting the number of bets using.
