Description

  The present invention relates to a slot machine.

  A slot machine generally includes three reels, a display window provided on the front surface of each reel, three reel stop buttons corresponding to each reel, and a start lever for starting a game. A plurality of symbols are arranged on each reel, and an area where one symbol is arranged is called a frame. In the display window, three symbols stop at symbol stop positions such as an upper stage, a middle stage, and a lower stage. A set of symbol stop positions of each display window is a winning position. Generally, the position of the winning position is as follows: the middle of each display window, the top of each display window, the bottom of each display window, the top of the left display window, the middle of the middle display window, the bottom of the right display window, and the left display window. There are the lower and middle display windows, the middle and right display windows, and each winning position is called a winning line.

  When the player depresses the start lever, all the reels rotate at the same time, and each reel stops at the timing when the player depresses each reel stop button. Of the combinations of symbols arranged on the winning line in a state where the reels are stopped, a combination of symbols that gives a game value is called a role. When a combination of symbols composing a combination on the effective winning line is completed, a winning is made, and the player can obtain the number of medals corresponding to the winning combination. That is, when the state where the reels are stopped is a state (predetermined state) that is a combination of symbols constituting the winning combination, the winning combination is awarded and a game value corresponding to the winning winning combination is given.

  Here, the winning is generally determined by two steps. The first step is called internal lottery. In the internal lottery, the lottery is executed at the operation timing of the start lever to determine which prize is won or lost, and internal lottery information indicating the lottery result is generated.

  In the second step, the reel stop position is controlled in accordance with the operation of the reel stop button. If the internal lottery information indicates a loss, even if the player operates the reel stop button at the timing when the symbol that constitutes a certain role reaches the valid winning line, the reel stop operation timing is delayed. Then, the reel is controlled so that the symbols constituting the combination do not stop on the effective winning line. The same applies to the combination corresponding to the prize that was not won in the internal lottery. Such control is called kicking control. On the other hand, if the prize which is an internal lottery is won, the drawing control is performed so that the symbols constituting the combination corresponding to the prize stop on the winning line even if the operation timing of the reel stop button is slightly early. The number of frames (hereinafter referred to as the number of advanced frames) that is required until the reel moves and stops after the reel stop button is operated is limited to four frames at the maximum. Here, if the operation timing of the reel stop button is greatly deviated, no prize is won. In other words, in order for a player to win a prize, it is necessary to win a prize by an internal lottery and align the winning combination on an effective prize line.

  As a reel stop control method, one using a stop table is known. The stop table stores a symbol number at the reference position and stop position information indicating the stop position in association with each other. The symbol number is assigned to each symbol arranged on the reel, and indicates the position of the reel at the reference position. An example of the stop position information is the number of advance frames. If the symbol number PN of the symbol at the reference position (middle stage) at the timing when the reel stop button is operated is the stop operation symbol number, the stop operation symbol number and the number of advance frames are stored in association in the stop data table. . For example, in the stop table shown in FIG. 29A, the number of advance frames of a maximum of 4 frames is recorded in association with the symbol number. In this case, when the reel stop button is operated at a certain timing, if the symbol number PN at the reference position (for example, the middle stage of the display window) is “5”, the advance frame number is “4”. If the reel rotates from top to bottom, the symbol 7 on the four frames stops at the middle stage of the display window. Similarly, if the symbol number PN = 6, 7, 8, 9, the advance frame number is “3, 2, 1, 0”, and the symbol 7 stops at the middle of the display window.

  As another mode of the stop position information, the data value is “1” at the stop position. Patent Document 1 discloses a 0/1 designation method in which a data value is “1” at a non-stop position. The stop table shown in FIG. 29B employs a 0/1 designation method. In this case, when the symbol number PN = 5 to 8, “0” is recorded. If the symbol number PN at the reference position is “5” when the reel stop button is operated, the data value “1” is obtained. The reel is rotated until the symbol number PN = 9 and stopped.

If the maximum number of advance frames is “4”, 3 bits must be assigned to one symbol number in the frame number designation method, but 1 bit is assigned to one symbol number in the 0/1 designation method. Therefore, there is an advantage that the amount of data can be reduced.
Japanese Patent Laid-Open No. 11-178987 (see FIG. 2)

  However, with the conventional 0/1 designation method, it is not possible to avoid unfair winnings or to freely derive the reach. This point will be described with reference to FIG. In this example, it is assumed that the BB prize (winning symbol 7-7-7) is won by internal lottery and the left reel and the middle reel have already stopped. At this time, the watermelon award (winning symbol watermelon-watermelon-watermelon) and the re-game award (winning symbol plum-plum-plum) are in temper. Assume that the symbol number PN at the reference position is 4 when the reel stop button corresponding to the right reel is depressed in this state. In the frame number designation method shown in FIG. 29A, since the number of advance frames is “2”, the plum of the symbol number PN = 6 is drawn to the middle as shown in FIG. 30 to win the watermelon prize and the plum prize. It can be avoided.

  On the other hand, in the 0/1 designation method, since the data value of the symbol number PN = 4 is “1”, the watermelon prize is not won. That is, in the 0/1 designation method, the symbols within the pull-in range where the data value is “0” cannot be stopped at the reference position. However, if the data value of PN = 4 is set to “0”, it is possible to avoid an unfair win, but in this case the number of leads will be “5”. There is a certain limit to the time from when the reel stop button is pressed down until the reel stops. For this reason, in a slot machine, the maximum number of pull-ins is generally set to “4”. Therefore, the conventional 0/1 designation method has a drawback that it cannot avoid an unfair win and the degree of freedom of the derived game is small.

  The present invention has been made in view of the above-described problems, and it is an object of the present invention to provide a slot machine that can increase the degree of freedom of the derived outcome while reducing the amount of stop data. To do.

  The present invention will be described below. In addition, in order to make an understanding of this invention easy, the reference sign of an accompanying drawing is appended as an example in the parenthesis writing, However, This invention is not limited to the form of illustration by it.

In order to solve the above-described problem, the slot machine according to the present invention has a plurality of display columns (R1, R2, R3) each having a plurality of frames, and symbols arranged in each frame, and capable of variable display of symbols. Corresponding to each of the start operation means (12) for the player to input the start of variable display of the display columns (R1, R2, R3) and each of the plurality of display columns (R1, R2, R3). And a plurality of stop operation means (13a, 13b, 13c) for allowing a player to input a variable display stop of the display columns (R1, R2, R3), and the plurality of display columns (R1 , R2, R3) in a state in which the variable display is stopped, a game corresponding to the winning prize is awarded when any of the symbols arranged on the winning line (L1 to L5) is in a predetermined mode. Value is added, and the stop operation means (13a, 13 , 13c), the maximum number of frames that are advanced until the variable display of the display row (R1, R2, R3) is stopped is set to the maximum number of frames, and a plurality of prizes and loses are selected by lottery. The lottery means (101, S103 to S105) for executing lottery as a target and generating lottery information indicating the lottery result, and the plurality of symbols arranged in each of the plurality of display columns (R1, R2, R3) Symbol numbers are assigned to the display columns (R1, R2, R3) corresponding to the stop operation means (13a, 13b, 13c) at the timing when the stop operation means (13a, 13b, 13c) is operated. A plurality of symbol number acquisition means (101, S109b) for acquiring the symbol number of the symbol corresponding to the reference position and the display columns (R1, R2, R3) are provided to stop variable display or A stop table (TBL101 to TBL103) that stores stop data indicating stop in 1 bit in association with the symbol number, and the lottery information indicates winning of any one of the plurality of prizes, and the stop operation At the timing when the means (13a, 13b, 13c) is operated, within the range of the maximum advance frame number from the winning line (L1 to L5) of the display row (R1, R2, R3) subject to stop control. In the case where there is no symbol constituting the prize, the display column (in order to prevent the lottery information from winning a prize other than the prize indicating winning based on the symbol number acquired by the symbol number acquisition means (101, S109b)). Selecting means (101, S109d to S109f) for selecting one from a plurality of stop tables (TBL101 to TBL103) corresponding to R1, R2, R3); Referring to the stop table (TBL101 to TBL103) selected by the selection means (101, S109d to S109f), the number of frames for generating the number of frames until the display row (R1, R2, R3) is stopped is acquired. Means (101, S109g) and stop control means for stopping variable display by advancing variable display of the display columns (R1, R2, R3) by the number of frames generated by the frame number acquisition means (101, S109g). 101, S109h), and when the symbol number is given by the symbol number acquisition means, the data corresponding to the symbol number is acquired with reference to a specific table, and the data value is “1” or “0”. If one of them is predetermined, it is stored in the table in the direction in which the symbol number at the reference position changes as the variable display progresses. Data retrieved until the data value is changed, and a analysis means for generating a number of retrieved data, wherein the selection circuits are provided corresponding to each of the plurality of stop table, the corresponding stop table A plurality of determination tables storing 1-bit determination data indicating whether the lottery information is not allowed to win a prize other than a prize indicating winning, in association with the symbol number, In the determination data stored in the determination table, the determination data indicating the permission among the determination data corresponding to a certain symbol number is stored in only one determination table, and the specific table is stored in the analysis unit. When the number of the retrieved data output from the analysis means is “0”, the stop table corresponding to the determination table is designated. When the number of the retrieved data is “1” or more, it is determined that the stop table corresponding to the determination table is invalid, and the symbol acquired by the symbol number acquisition unit Based on the number, the stop table is selected according to the determination data obtained by referring to the plurality of determination tables, and the frame number acquisition means sets the stop table as the specific table to the analysis means. The stop control means is controlled by designating and acquiring the number of searched data as the number of frames by the analysis means .

  According to the present invention, since stop data indicating stop or non-stop of variable display by 1 bit is stored in the stop table, the storage capacity can be reduced as compared with the case of storing the number of advance frames. . Even if winning in the internal lottery, if the winning operation is not performed due to the operation timing of the stop operation means, it is necessary to control the display row so as not to win other prizes. In this regard, in the conventional 0/1 system, the number of stop tables is limited to one, so that an unfair winning prize cannot be avoided. In the present invention, since a plurality of stop tables are prepared in advance and the table is selected based on the stop operation symbol number, it is possible to avoid an unfair win. Furthermore, when a winning flag such as a BB prize or an RB prize is carried over, it is possible to inform a player that a specific outcome such as a so-called reach eye has been derived and missed.

  In other words, the selection means selects one of the plurality of stop tables so that the lottery information does not win a prize other than the prize indicating winning by executing the selection based on the symbol number. A plurality of symbol stop positions at which symbols stop when the display columns are stopped are set for each display column, and a combination of symbol stop positions selected for each display column is a winning line. When a predetermined symbol is arranged on the winning line, a winning is achieved. In order to avoid winning, a symbol that does not constitute a prize within the range of the maximum advance frame number may be stopped on the winning line after the stop operation means is operated. The position of the display row at the timing when the stop operation is performed is specified by the symbol number. Therefore, by selecting the stop table based on the symbol number, it is possible to bring a symbol that does not constitute a prize within the range of the maximum advance frame number onto the winning line and stop it. A plurality of stop tables prepared in advance are preferably provided corresponding to a plurality of symbol stop positions provided for each display row. For example, if a predetermined prize is tempered on a certain winning line, the selection means may execute the selection of the stop table so that the symbols constituting the predetermined prize do not stop at the symbol stopping position on the winning line. Good.

Further, one of the plurality of symbol stop positions is specified by the stop table selected by the selection means, and a predetermined symbol is stopped at the specified symbol stop position. If a predetermined symbol is determined in one display row, the relative positional relationship of other symbols is also determined. Therefore, the function by which the selection means selects the stop table determines at which symbol stop position the symbols constituting the prize whose winning information is determined by the lottery information are stopped. Thereby, the determination of the symbol stop position conventionally required can be omitted.
The analysis means can be used to determine the validity of the stop table and can be used to generate the number of advance frames. As a result, the processing can be simplified. For example, when the analyzing means is composed of a computer program and a CPU, the analyzing means can be used as a shared module.

  The selection means may select from a plurality of stop tables when there is a possibility of winning by internal lottery and winning. Further, for example, there are three display columns, and in the first stop, stop control is executed using the selection means described above, and when there is no possibility of winning in the second stop, a predetermined stop table is displayed. The display row may be stopped without using the selection means described above. Further, the selection means may select one from a plurality of stop tables when the internal lottery is lost. Even in such a case, if there is no possibility of winning in the game won in the internal lottery, there is no change in selecting one from a plurality of stop tables. Of course included.

The slot machine according to the present invention includes a plurality of display columns each of which has a plurality of frames, and symbols are arranged in each frame, and the player can start variable display of the display columns. Start operation means for inputting, and a plurality of stop operation means provided corresponding to each of the plurality of display columns, for a player to input stop of variable display of the display columns, In the state where the variable display of the display column is stopped, if the arrangement of the symbols stopped on the winning line is in a predetermined mode, the player wins one of the prizes, and gives the game value according to the winning prize, and the stop A slot machine having the maximum number of frames that are advanced from the time when the operation means is operated until the variable display of the display row is stopped as a maximum number of frames, and a lottery is performed for a plurality of prizes and loses. Lottery information showing lottery results A lottery means for generating a symbol number and a plurality of symbols arranged in each of the plurality of display columns are respectively assigned symbol numbers, and corresponds to the stop operation means at a timing when the stop operation means is operated. Symbol number acquisition means for acquiring the symbol number of the symbol located at the reference position of the display column, a plurality of symbol numbers provided for each display column, stop data indicating stop or non-stop of variable display in one bit, and the symbol number A plurality of stop tables stored in association with each other and each of the plurality of stop tables is provided, and the selection of the corresponding stop table is permitted so that the lottery information does not win a prize other than a prize indicating winning. A plurality of determination tables storing 1-bit determination data indicating whether or not the symbol numbers are associated with each other, and winning of any one of the plurality of prizes as the lottery information The symbol number acquisition is performed when there is no symbol constituting the prize within the range of the maximum number of advance frames from the winning line of the display row to be stopped at the timing when the stop operation means is operated. Selection means for selecting one from a plurality of stop tables corresponding to the display row so that the lottery information does not win a prize other than the prize indicating winning based on the symbol number acquired by the means; With reference to the stop table selected by the selection means, a frame number acquisition unit that generates the number of frames until the display column is stopped, and the display column is variable by the number of frames generated by the frame number acquisition unit. Stop control means for advancing display and stopping variable display, and in the determination data stored in the plurality of determination tables, the determination data among the determination data corresponding to a certain symbol number The determination data indicating allowance is stored in only one determination table, and the plurality of stop tables and the plurality of determination tables are a plurality of data tables in which data indicated by 1 bit is stored in association with the symbol number. The determination data obtained by referring to the data table managed as the plurality of determination tables among the plurality of data tables based on the symbol number acquired by the symbol number acquisition unit. The data table managed as the plurality of stop tables among the plurality of data tables is selected as the stop table, and some of the data tables out of the plurality of data tables are It is managed as a table and the determination table.
According to the present invention, the stop table and the determination table are stored with 1-bit data associated with the symbol number. Therefore, the data structure is the same, and the stop table and the determination table can be shared. As a result, the amount of data can be greatly reduced.

Further, in the slot machine described above, when the final stop operation is performed, the lottery information indicates winning of any prize, and the symbols constituting the winning prize are displayed from the winning lines (L1 to L5). When the determination condition is affirmed by the determination means (101, S109v) for determining whether or not the number is within the maximum advance frame number, and the determination means (101, S109v), the display sequence corresponding to the last stop operation ( The frame number determining means for determining the number of frames by referring to the layout data indicating the layout of the symbols for R1, R2, and R3) so as to stop the symbols constituting the winning prize on the winning line (L1 to L5). When the determination condition is denied by (101, S109y) and the determination means (101, S109v), the symbol number and the number of advance frames are stored in association with each other so as not to win. Referring to the non-winning stop tables (TBL311a to TBL313a), the frame number specifying means (101, S109x) for specifying the corresponding advance frame number based on the symbol number acquired by the symbol number acquiring means (101, S109b) The stop control means (101, S109h) includes a lottery information indicating winning of any one of the plurality of prizes in a stop operation immediately before the last from the beginning , and the stop operation means operates Is acquired by the frame number acquisition means (101, S109g) when there is no symbol constituting the award within the range of the maximum advance frame number from the winning line of the display row subject to stop control at the determined timing. The variable display of the display row (R1, R2, R3) is advanced by the number of frames that have been made to stop the variable display. The variable display of the display row (R1, R2, R3) is advanced by the number of frames obtained by the frame number determining means (101, S109y) or the frame number specifying means (101, S109x) to stop the variable display. It is preferable.

  According to the present invention, if there is a possibility of winning in the final stop operation, it is possible to stop by drawing a predetermined symbol on the winning line by so-called control control without using a stop table. On the other hand, in the case of non-winning, the display row is stopped by table control. Therefore, as a stop table, it is possible to store stop data that does not allow other prizes to be awarded or that leads to specific outcomes such as reach eyes, assuming there is no possibility of winning. It becomes. When there is a possibility of winning, the symbols constituting the prize can be drawn on the winning line and stopped.

<2: Configuration of variable reel display device>
FIG. 2 is an explanatory view showing the structure of the reel variable display device RL of the slot machine 1. 2A shows the entire structure of the reel variable display device RL, and FIG. 2B shows the detailed structure of the right reel R3. FIG. 2A shows a state in which the right reel R3 is removed to show the inside of the variable reel display device.

  The reels R1 to R3 are made of transparent ABS resin or the like, and are affixed to the reel frames 56a to 56c composed of a plurality of spoke portions and an annular frame extending radially from the shaft portion, and the peripheral surfaces of the reel frames 56a to 56c. It is composed of reel bands 58a to 58c on which 21 various symbols (symbol numbers PN = 1 to 21) are printed. The reels R <b> 1 to R <b> 3 are inserted along guide rails 51 a to 51 c corresponding to the respective reels provided above and below the case body 50 of the reel variable display device RL, and are accommodated in the case body 50. The reel R3 will be described with reference to FIG. 2B, but the reels R1 and R2 have the same structure. The reel R3 is fixed to the stepping motor 54c and rotates. For the rotation operation of the reel R3, a stepping motor 54c that rotates once by supplying a pulse of 400 steps is used, and a predetermined symbol can be displayed on the reel window 20 by supplying a predetermined pulse. Further, a backlight device 53c provided with LEDs (not shown) is provided so that light can be irradiated from the inside of the reel band 58c. Thus, by irradiating light from the inside of the reel band 58c by the backlight device 53c, the player can make the symbols on the reel band 58c stand out.

  A detection plate 57c is attached to one of the spoke portions, and a reel position detection signal 55c can be output by the reel position detection sensor 55c every time the reel R3 rotates once. The position of the detection plate 57c and the reel band 58c is set so that the symbol number PN = 1 is positioned on the winning line L1 at the center of the reel window 20 when 10 steps are advanced after detecting the reel position detection signal 155c. It is set.

  The reel R3, the stepping motor 54c to which the reel R3 is fixed, the backlight device 53c, and the reel position detection sensor 55c are fixed to the base plate 52c to form one unit. Further, the reel variable display device RL is configured such that the base plate 52c is inserted along the guide rail 51c provided on the case body 50 of the reel variable display device RL and accommodated in the case body 50. Although the stepping motor 54c, the backlight device 53c, the detection plate 57c, the reel position detection sensor 55c, and the reel position detection signal 155c are not shown, in the reel R1, the stepping motor 54a, the backlight device 53a, the detection plate 57a, the reel The reel R2 corresponds to the position detection sensor 55a and the reel position detection signal 155a, and the reel R2 corresponds to the stepping motor 54b, the backlight device 53b, the detection plate 57b, the reel position detection sensor 55b, and the reel position detection signal 155b.

  FIG. 3 is an explanatory diagram showing the arrangement of symbols printed on the reel bands 58a to 58c. On the left, middle, and right reels, 21 symbols are printed at equal intervals. Since stepping motors 54a to 54c that rotate once by supplying pulses of 400 steps are used, when 21 symbols are arranged, the interval between symbols is 19 steps. Further, since the symbol number PN = 1 is positioned on the winning line L1 at the center of the reel window 20 when 10 steps are advanced after the reel position detection signals 155a to 155c are detected, the reel position detection signal 155a. If the process proceeds 29 steps after detecting ~ 155c, the symbol number PN = 2 is positioned on the winning line L1, and if the step 48 is advanced, the symbol number PN = 3 is positioned on the winning line L1, and if the step is advanced 390 The symbol number PN = 21 is positioned on the winning line L1. If the processing proceeds beyond step 390, reel position detection signals 155a to 155c are detected again. Thereby, a predetermined symbol can be positioned on the winning line L1 by the number of steps to be advanced based on the timing at which the reel position detection signals 155a to 155c are detected. The symbol arrangement on the reel band is stored as symbol code PC data such as “01” for red 7 symbols and “07” for plum symbols as described in parentheses in FIG. ing.

<4-2: Slot machine awards and roles>
FIG. 6 is an explanatory diagram for explaining a prize and a combination in the slot machine 1, and shows a configuration of a prize type and its combination (a combination of symbols). In the slot machine 1, a prize is awarded when a predetermined symbol combination is aligned on the activated prize line, and a small prize is awarded with a maximum of 15 medals based on the number of prizes determined by the combination. There are also prizes for starting other types of games from regular games.

  As a prize for starting another type of game, a BB1 award consisting of a combination of symbols “red 7-red 7-red 7” (also referred to as a BB1 role) for starting a BB1 game, and “white 7- for starting a BB2 game” There is a BB2 award consisting of a combination of symbols “White 7-White 7” (also referred to as a BB2 role) and an RB award consisting of a combination of symbols “BAR-BAR-BAR” (also referred to as an RB role) for starting an RB game. Each content of the BB1 game and the BB2 game can be arbitrarily set as long as the definition of the BB game is followed. In addition, the BB1 game and the BB2 game may be games with different winning roles for the small role prize, may be games with different numbers of medals as end conditions, or may be the same game. . Hereinafter, when it is not necessary to distinguish between BB1 and BB2, they are collectively referred to simply as BB.

<4-3: Explanation of various games in the slot machine>
FIG. 7 is an explanatory diagram showing the types of games played in the slot machine 1.
(1) Start and end of the BB game In FIG. 7A, the slot machine 1 wins the BB prize by the internal lottery during the normal game, and when the BB role is established and the prize is won, the BB game starts from the next game. Is done. The BB game is ended when the acquired number of sheets in the BB game exceeds the specified number.
(2) BB inside game Even if the BB prize is won in the internal lottery during the normal game, if the BB role is not established, the BB prize winning flag will be carried over until the next game is won. Become. When the BB combination is established in the BB1 internal game and a prize is won, the BB game is started from the next game.
(3) Start and end of the RB game When the RB prize is won by the internal lottery during the normal game and the RB combination is established and won, the RB game is started from the next game. A maximum of 12 RB games are played, and when the RB game is won eight times, the RB game is terminated.
(4) RB inside game When the RB prize is won by an internal lottery during a normal game, if the RB role is not established, the winning flag of the RB prize is carried over until the next game is won and Become. When the RB combination is established and a prize is won in the RB inside game, the RB game is started from the next game.

(5) Modified Example of BB FIG. 7B is a modified example of the BB game performed in the slot machine 1. When the BB prize is won by the internal lottery during the normal game and the BB role is established and won, the BB game is started from the next game, and the BB normal game is started first. The BB normal game is a game in which the lottery probability of the RB prize varies as compared with the normal game. During the BB regular game, the RB prize is won by internal lottery. When the RB role is established and won, the RB game (RB game during BB) is started from the next game, and when the RB game is won eight times during the RB game, the RB game is ended. . The BB game is terminated when the number obtained in the BB game reaches the prescribed number or exceeds the prescribed number in the next payout.

<5: Operation of slot machine>
Next, details of the overall operation of the slot machine 1 will be described. The CPU 101 performs an initialization process after turning on the power, and executes the process of the flowchart shown in FIG.

<5-1: 1 game flow>
FIG. 8 is a flowchart showing the contents of the flow of one game. First, based on the medal insertion signal 160 or the bet operation instruction signals 111a to 111c, the CPU 101 determines whether or not an insertion bet operation by inserting a medal or a storage bet operation by pressing the bet button 11 has been performed. Wait until it is detected (S100). When the signal is detected, the process proceeds to the next, and it is determined whether or not the start lever operation has been performed based on the start operation instruction signal 112, and waits until the signal is detected (S101). When the signal is detected, the betting operation is prohibited (S102). More specifically, the solenoid of the medal selector device is turned off by the medal block signal 161, the passage route of the medal selector device is switched, and the game medal is discharged to the medal tray 40 even when it is inserted from the medal insertion slot 10. Also, bet operation instruction signals 111a to 111c are not accepted.

  Next, the CPU 101 sequentially increments every 10 nanoseconds in the range of 0000H to 3FFFH, acquires a counter value from the counter circuit that makes one round in about 1.6 milliseconds via the input / output port 107, and makes it a random value. (S103). Next, referring to the game type data, a prize lottery table corresponding to the type of the game is selected (S104). Using the selected prize lottery table, it is determined which numerical range set for each prize on the prize lottery table the acquired random number value belongs to, and a winning flag for the prize is set (S105). . Next, a stop link table to be referred to in stop control is selected based on the winning flag set in step S105 (S106). The detailed data structure of the stop link table will be described later (see FIG. 13).

  In this embodiment, since the minimum consumption time of one game is 4.1 seconds, the timer value that counts down to 0 every 2 milliseconds indicating the elapsed time of one game is referred to until the timer value reaches 0. Wait (S107). When the timer value reaches 0 to start rotation of the reel as a starting point for measuring the elapsed time of one game, the timer value is set to an initial value (2050) corresponding to 4.1 seconds, and three reels To drive the reel drive signals 154a to 154c to rotate the stepping motor simultaneously or sequentially (S108). Specifically, each of the reel drive signals 154a to 154c includes a plurality of drive signal lines for exciting a plurality of winding phases, and a reel is supplied by supplying a pulse signal to each drive signal line in a predetermined phase pattern. Rotate. Also, even if the start lever is operated in step S101, if 4.1 seconds have not elapsed since the start of rotation of the reel of the previous game, the reels R1 to R3 immediately enter a standby state without rotating and enter a standby state. Inform the player of this by a lamp or sound.

  Next, the CPU 101 detects that the three reels R1 to R3 have reached a constant rotational speed after all the three reels R1 to R3 have reached a constant rotational speed through an acceleration period of 10 steps. Is used as a reference time, and measurement of the remaining time from the reference time until the automatic stop time elapses is started, and an LED incorporated in the stop button is lit to notify that the stop buttons 13a to 13c can be received. Specifically, it is detected that the pulse width of the reel drive signals 154a to 154c supplied to the drive signal line of the stepping motor is constant, and this detection time is used as a reference time, and counts down to 0 every 2 milliseconds. A value indicating a predetermined automatic stop time (for example, 30 seconds) is set as an initial value of the timer value. At this time, the LED built in the stop button corresponding to each reel is turned on.

  In addition, as a method of detecting that the three reels R1 to R3 have reached a constant rotation speed, after a predetermined number of steps have elapsed from the start of rotation, or after a predetermined time has elapsed from the start of rotation (a predetermined number of interruptions have occurred) A method of assuming that a constant rotational speed has been reached by outputting pulses at regular intervals to the stepping motor, or after a predetermined number of steps have elapsed since the start of rotation, or after a predetermined time has elapsed since the start of rotation (a predetermined number of interruptions have occurred) There is a method of determining that a predetermined rotational speed has been reached when a predetermined time has elapsed, a predetermined number of steps have elapsed, a stepping motor has made one revolution, or an index has been detected. That is, in this embodiment, the time point at which the constant rotational speed is detected is set as the reference time point, but the time point at which it is considered that the constant rotational speed is reached may be set as the reference time point.

  Then, the CPU 101 performs a reel stop process for stopping the three reels R1 to R3 (S109). As will be described in detail later, in the reel stop process, when stop operation instruction signals 113a to 113c are detected and the stop button is operated, the position of the stop button operation based on the stop link table selected in step S106. The symbol number PN to be stopped is determined from the stop data in the stop data table, the braking force is applied by all-phase excitation that simultaneously excites all winding phases, and the inertia corresponding to 15 steps is started after starting all-phase excitation. While the reel stop process for rotating and stopping at each of the reels is performed, when the automatic stop time elapses from the reference time point (when the remaining time runs out), the reels that have not been stopped are automatically stopped. .

  Next, when all reels are stopped, the CPU 101 determines whether or not a winning combination is established on a valid winning line (S110), and if winning, a game value set for each winning combination is given. To do. Next, a game end determination process is performed (S111), and then a winning flag clear process is performed (S112). Here, if the winning flag established in the game is a start prize that the flag can be carried over, the winning flag is cleared only when winning, and the winning flag is not cleared if it is missed without winning. . On the other hand, if the winning flag established in the game is a start prize or a small part prize that the flag cannot carry over, the winning flag is cleared regardless of winning or missing. Subsequently, the prohibition of the bet operation performed in step S102 is canceled (S113), so that the insertion of a game medal or the input of the bet button 11 can be performed, and the process returns to step S100 to prepare for the start of the next game.

<5-2: Prize lottery table determination process>
FIG. 9 is an explanatory diagram showing an example of lottery using the prize lottery table selected in the prize lottery table determination process in step S104. During the regular game, the lottery probabilities for determining either the small role C prize, the small role B prize, the small role A prize, the RB prize, the BB2 prize, the BB1 prize, the replay prize, or the loss are determined by lottery. 200/16384 "," 910/16384 "," 300/16384 "," 200/16384 "," 75/16384 "," 75/16384 "," 2250/16384 "," 12374/16384 " The lottery is performed using the prize lottery table TBL11 in which data indicating the lottery probability is stored, and the winning flag of the winning prize is set.

  In the prize lottery table TBL11, the lottery classification data “200” of the small role C prize is stored in the first memory area of the prize lottery table indicated by the table storage address ADR11, and the obtained random number value belongs to the range of 0 to 199. The case indicates that the small role C prize has been won. In the storage area offset 02H from the top of the prize lottery table, the lottery B prize lottery classification data “910” is stored, and if the obtained random number value is in the range of 200 to 1109, the prize is assigned to the small role B prize. Shows that you have won. In the storage area offset by 04H from the top of the prize lottery table, the lottery A prize lottery classification data “300” is stored, and if the obtained random number value falls within the range of 1110 to 1409, the prize is assigned to the small role A prize. Shows that you have won. The storage area offset by 06H from the top of the prize lottery table stores the RB prize lottery classification data “200”. If the obtained random number value is in the range of 1410 to 1609, it means that the RB prize is won. Show. The storage area offset by 08H from the beginning of the prize lottery table stores the lottery classification data “75” for the BB2 prize. If it belongs to the range of 1610 to 1684, it indicates that the BB2 prize is won. In the storage area offset by 0 AH from the top of the prize lottery table, the lottery classification data “75” of the BB1 prize is stored, and if the acquired random number value belongs to the range of 1685 to 1759, it means that the BB1 prize is won. Show. The re-game award lottery classification data “2250” is stored in the storage area offset by 0 CH from the top of the award lottery table. If the obtained random number value is in the range of 1760 to 4009, the re-game award is won. It shows that. In addition, the data of the range of the numerical value belonging to the lose is not stored, and the obtained random number value is sequentially compared with the lottery classification data from the small role C prize to the re-game prize, and determined not to belong to any range. If you're lost. The prize lottery tables TBL12 to 16 described later are the same as the prize lottery table TBL11 except that the prizes to be lottery and the range of numerical values are different.

  FIG. 10 is an explanatory diagram showing the relationship between the prize lottery table selected in the prize lottery table determination process in step S104 and the type of game being executed. During the normal game, the prize lottery table TBL11 indicated by the ADR 11 is selected. During the BB internal game, the prize lottery table TBL12 indicated by the ADR 12 is selected, and during the RB internal game, the prize lottery table TBL13 indicated by the ADR 13 is selected. During the BB1 game, the prize lottery table TBL14 indicated by ADR14 is selected, during the BB2 game, the prize lottery table TBL15 indicated by ADR15 is selected, and during the RB game, the prize lottery table TBL16 indicated by ADR16 is selected.

  The winning probabilities of the small role C prize, the small role B prize, the small role A prize, and the replay prize in the BB internal game and the RB internal game are set to be the same as in the normal game. Also, the RB prize, BB2 prize, and BB1 prize lottery probabilities in the BB inside game and RB inside game are each “0/16384” and are not subject to lottery.

  During the BB game and the RB game, the lottery probabilities for determining any one of the small role C prize, the small role B prize, the small role A prize or the loser by lottery are “200/16384” and “15800/16384”, respectively. , “300/16384” and “84/16384”, and the winning flag of the winning prize is set. Thus, during the BB game and during the RB game, the lottery probability of the small role B prize is higher than that during the normal game and the inside game. In this embodiment, in the BB game, only the small role B prize has a high probability of lottery, but the small role A prize, the small role B prize and the small role C prize are all high probability, or the small role A prize, The B prize and the small part C prize may have the same lottery probability as that of the base game or the internal medium game, and a small part prize dedicated to the BB game or the RB game may be provided. In any case, during the BB game, the combination probability of the small role award (the sum of the lottery probabilities of a plurality of small role awards) is higher than that during the normal game and the internal middle game.

<5-3: Winning flag set processing>
FIG. 11 is a flowchart showing the contents of the winning flag setting process in step S105. In this winning flag setting process, a winning flag effective for the game is set from the acquired random number value and the prize lottery table corresponding to the type of game determined in step S104. If the prize lottery table is different, the winning flag to be set is also different, and even if the random number value is different even in the same prize lottery table, the winning flag to be set is also different. In addition, when there is a carry-over flag that is a win flag carried over from the previous game, at least one win flag is set by combining the carry-over flag and the random value acquired in the game.

  First, the CPU 101 determines whether or not the small role C prize has been won based on whether or not the acquired random number value belongs to the range indicated by the lottery division data of the small role C prize in the prize lottery table (S105a). If it is determined, the small combination C winning flag of bit 3 of the winning information 2 data is set to “1” (S105a1).

  Next, the CPU 101 determines whether or not the small role B prize has been won based on whether the acquired random number value belongs to the range indicated by the lottery division data of the small role B prize in the prize lottery table (S105b). If it is determined, the small combination B winning flag of bit 2 of the winning information 2 data is set to “1” (S105b1).

  Next, the CPU 101 determines whether or not the small role A prize is won based on whether or not the acquired random number value belongs to the range indicated by the lottery classification data of the small role A prize in the prize lottery table (S105c). Is determined, the small combination A winning flag of bit 1 of the winning information 2 data is set to “1” (S105c1).

  Next, the CPU 101 determines whether or not the normal game is being played by checking whether any of the bits 0 to 7 of the game type data is set to “1” (S105d). If it is set to “1” and it is determined that the base game is not being played, the process proceeds to step S105j. When it is determined in step S105d that the base game is being played, whether or not the RB prize is won is determined based on whether or not the acquired random number value belongs to the range indicated by the lottery classification data of the RB prize in the prize lottery table ( If it is determined that it belongs, the RB winning flag of bit 3 of the winning information 1 data is set to “1” (S105e1).

  Next, the CPU 101 determines whether or not the BB2 prize has been won based on whether or not the acquired random number value belongs to the range indicated by the lottery classification data of the BB2 prize in the prize lottery table (S105g). In such a case, the BB2 winning flag of bit 1 of the winning information 1 data is set to “1” (S105g1).

  Next, the CPU 101 determines whether or not the BB1 prize has been won based on whether or not the acquired random number value belongs to the range indicated by the lottery classification data of the BB1 prize in the prize lottery table (S105h). In such a case, the BB1 winning flag of bit 0 of the winning information 1 data is set to “1” (S105h1).

  Next, the CPU 101 determines whether or not the BB game or the RB game is in progress by checking whether any of the bits 0 to 3 of the game type data is set to “1” (S105j). If it is determined that the game is being played or the RB game is being played, this process is terminated. If it is determined in step S105j that the BB game or the RB game is not being played, whether the re-game prize is won or not is included in the range indicated by the lottery division data of the re-game prize in the prize lottery table. (S105k), and if it is determined that it belongs, the re-game winning flag of bit 0 of the winning information 2 data is set to “1” (S105k1), and the process is terminated.

  In addition, in the flowchart shown in FIG. 11, when there is a carry-over flag from the previous game, it is clearly indicated that when a new prize is won in this game, a plurality of winning flags are set simultaneously. However, when a new prize is won, a bit corresponding only to the prize is set to “1” without affecting other bits, so that a plurality of bits may be set to “1” at the same time. . In this example, the winning information 1 data is divided as the storage device for storing the winning flag corresponding to the start prize, and the winning information 2 data is stored as the storing device for storing the winning flag corresponding to the replay prize and the small role award. You may make it memorize | store with the memory | storage device. The plurality of bits being “1” means that the plurality of bits are “1” considering the winning information 1 data and the winning information 2 data together. In addition, as winning information, a flag is managed as information indicating whether or not a prize is assigned to each bit. However, if it is “01H”, a re-game prize is won, and if it is “02H”, a small role A prize is won. You may make it manage with.

<5-4: Stop data selection process>
FIG. 12 is a flowchart showing the contents of the stop link table selection process in step S106. In this stop link table selection process, stop data that selects stop link tables TBL21 to TBL29 set for each award used in stop control from the winning flag set in step S105, and specifies the stop position according to the stop operation order. Stop display while sequentially selecting tables. FIG. 13 is an explanatory diagram showing the data structure of the stop link table. The stop link table is classified for each prize to be a lottery target of the internal lottery. FIG. 13A shows the stop link table TBL21 for replay, FIG. 13B shows the stop link table TBL23 for small role B, FIG. (C) shows the stop link table TBL27 for BB1. The stop link tables TBL21 to TBL29 are classified when the first stop operation is the left reel R1, the middle reel R2, and the right reel R3, and the symbols constituting the award are displayed in the upper, middle, and lower stages. It is classified according to which one is stopped, and further classified according to the type of winning line.

  The stop link table has a function of associating stop data used in the first stop, the second stop, and the third stop. For example, paying attention to the replay stop link table TBL21 shown in FIG. 13A, the stop data table TBL102 for pulling the plum symbol to the upper stage for the left reel is associated with the following table. 1) TBL102-TBL202, 2) TBL102-TBL302, 3) TBL102-TBL201, 4) TBL102-TBL303.

  The structure of the table will be described using the replay stop link table TBL21 shown in FIG. The stop link table is divided into three data groups (a) to (c) depending on whether the first stop operation is the left reel R1, the middle reel R2, or the right reel R3. That is, when the re-game prize is won and the first stop operation is the left reel R1, the data group (a) of the TBL 21 is selected, and when the first stop operation is the middle reel R2. The data group (b) of TBL21 is selected, and when the first stop operation is the right reel R3, the data group (c) of TBL21 is selected.

  Next, the stop data table to be used for the first left reel R1 is selected depending on whether the plum symbol constituting the combination related to the replay prize is stopped at any one of the upper, middle and lower stages. The selection of whether the symbol is to be stopped at the upper, middle or lower level will be described in detail later, but the symbol to be stopped at the reference position (middle level) at the player's stop operation timing is displayed on which level. There are a method of previously setting for each stop operation symbol position, a method of determining at which stage the stop operation symbol position can be stopped, and a method of determining by lottery when there are a plurality of candidates. In the case of a game in which only one winning line (L1 line) is valid, it is determined as the middle stage.

  In the present embodiment, a method is adopted in which a stage in which a symbol to be stopped is displayed in advance for each stop operation symbol position in accordance with the stop operation symbol position at the stop operation timing of the player. More specifically, the CPU 101 selects the upper stop data table TBL102, the middle stop data table TBL101, and the lower stop data table TBL103 according to the stop operation symbol number. For this selection, a validity determination data table is used. FIG. 21 shows rejuvenation validity determination data tables 101L to 103L. The validity determination data tables 101L, 102L, and 103L are associated with the stop data tables 101, 102, and 103, respectively. In addition, when it is necessary to select a plurality of stop data tables to be used for stop control, a validity determination data table is prepared in advance for each of the plurality of stop data tables to be selected. These validity determination data tables are stored in the ROM 104. Note that the validity determination data table only needs to be associated with the stop data table, and does not necessarily have to be associated one-to-one. That is, one validity determination data table may be shared by a plurality of stop data tables.

  Each validity determination data table 101L to 103L stores a symbol number PN and 1-bit determination data in association with each other. Here, when the data value of the determination data is “1”, the corresponding stop data table is valid, and when the data value is “0”, it is invalid. For example, it is assumed that the symbol number of the symbol located at the reference position (for example, the middle stage) at the timing when the reel stop button is pressed is PN = 21. In this case, the data values of the determination data recorded in the validity determination data tables TBL101L to 103L are “0”, “0”, and “1”. Therefore, the stop data tables TBL101 and TBL102 are invalid, and the stop data table TBL103 is valid. In this example, in the plurality of validity determination data tables 101L to 103L associated with the plurality of stop data tables TBL101 to TBL103 to be selected, the data value of the determination data corresponding to a certain symbol number is “1”. There is only one validity determination table. Therefore, it is possible to select one from a plurality of stop data tables by referring to the data value.

  Note that a plurality of validity determination tables in which the data value of the determination data corresponding to a certain symbol number is “1” may be provided. In this case, one of the plurality of stop data tables corresponding to the validity determination table with the data value “1” may be selected by lottery, or may be selected according to a predetermined rule. For example, if the re-game prize is won by internal lottery, if the plum symbol may be stopped at either the upper or lower level, determination data corresponding to a certain symbol number in the validity determination data tables 102L and 103L The data value of “1” may be “1”.

  Returning to FIG. For example, when the left reel R1 is selected by the first stop operation and the data group (a) of TBL21 is selected, the stop data table TBL102 is selected to stop at the upper stage of the left reel R1, and stopped at the middle stage. Sometimes the stop data table TBL101 is selected, and when stopping at the lower stage, the stop data table TBL103 is selected. Here, when the stop data table TBL103 is selected and the plum symbol is displayed in the lower stage of the left reel R1, the lower stage of the left reel R1 includes the L3 line and the L5 line included in the winning line in the second stop operation. Be a candidate. Further, stop data to be selected depending on whether the second stop operation is the middle reel R2 or the right reel R3 is determined by the stop operation order. That is, when the middle reel R2 is selected in the second stop operation, the stop data table TBL203 displayed in the lower row or the stop data table TBL201 displayed in the middle row is selected. On the other hand, when the right reel R3 is selected in the second stop operation, the stop data table TBL303 displayed in the lower row or the stop data table TBL302 displayed in the upper row is selected. For example, when the stop data table TBL201 is selected and the plum symbol is displayed in the middle row of the middle reel R2, the plum symbol is arranged on the winning line L5 so that it becomes the upper row of the remaining right reel R3 in the third stop operation. Is displayed. As will be described later, in the stop control of the third stop, is there a possibility that the symbols related to the prize won in the internal lottery will be awarded in the range of 4 frames ahead of the stop operation symbol position at the operation timing? If a determination function (steps S109u to S109v) for determining whether or not there is a possibility of winning, stop control is performed so that the winning symbols are aligned on the winning line. However, all the symbols on the display line are included in the maximum number of symbols that can be drawn in the Plum symbols that make up the re-game prize, and the Plum symbols can always be displayed on the winning line by the pull-in control. Therefore, since the re-game prize is always determined to be a win by the determination function, a stop data table dedicated to non-wins is not provided. In the case of a small role A prize that is awarded based on an array of watermelon symbols that have been missed, if there is no possibility of winning, a stop data table dedicated to non-winning is selected, and combinations of symbols related to all winning prizes are awarded. Stop control is performed so that they are not aligned on the line.

  When the middle reel R2 is selected by the first stop operation and the data group (b) of the TBL 21 is selected, only the TBL 201 to be stopped at the middle stage of the middle reel R2 can be selected and stopped at the upper stage and the lower stage of the middle reel R2. Since it is not possible, the plum symbol is displayed in the middle. Next, when the second stop operation is the left reel R1 and the right reel R3, TBL101 or TBL301 is selected and displayed so that the plum symbols are arranged only on the pay line L1.

  Similarly, when the right reel R3 is selected by the first stop operation and the data group (c) of the TBL 21 is selected, only the TBL 301 to be stopped at the middle stage of the right reel R3 can be selected. Since it cannot be stopped at the bottom, the plum symbol is displayed in the middle. Next, when the second stop operation is the left reel R1 and the middle reel R2, TBL101 or TBL201 is selected and displayed so that the plum symbols are arranged only on the pay line L1.

  In the small link B stop link table TBL23 shown in FIG. 13 (B), when the data group (a) of TBL23 is selected, the bell symbol is displayed according to the stop operation symbol position of the player's stop operation timing. Display on either the top, middle or bottom. On the other hand, when the data group (b) of TBL23 or the data group (c) of TBL23 is selected, the bell symbols are displayed so as to be arranged on the winning line L3 or L5. Further, since the bell symbol of the small role B prize is a 100% pull-in symbol as in the case of the plum symbol, the small role B award is always determined to be a winning by the determination function, and therefore a stop data table dedicated to non-winning is provided. Absent.

  In the stop link table TBL27 for BB1 shown in FIG. 13C, even if the data group of (a) of TBL27, (b) of TBL27, or (c) of TBL27 is selected, the stop operation at the stop operation timing of the player Depending on the symbol position, the red 7 symbols are displayed on every winning line.

  As described above, the stop link table stores the table number indicating the stop data table to be selected according to the operation sequence of the stop operation and the display position of the upper, middle or lower stage, the address storing the table, or the like. An example of a stop data table group TBL31 storing a plurality of stop data tables is shown in FIG. This stop data table group TBL31 is divided into reels R1 to R3, and is a stop data table TBL101 set so that the symbol arrangement corresponding to each prize in the first to second stop control shown in (A) is aligned on the winning line. Stop data tables TBL111a to TBL163a to TBL211a to TBL163, TBL201 to TBL263, TBL301 to TBL363, and symbols arranged in accordance with all prizes in the third stop control shown in FIG. Consists of TBL263a, TBL311a to TBL363a ("a" at the end of the table number) and stop data tables TBL171 to TBL179, TBL271 to TBL279, TBL371 to TBL379 common to the first to third stop controls according to the loss The To have. The watermelon symbol constituting the small role A prize, the cherry symbol constituting the small role C award, and the like are provided with stop data tables TBL131a to TBL333a and TBL111a to 313a dedicated to non-winning prizes. On the other hand, since the symbols constituting each of the re-game award and the small role B award are 100% drawn-in symbols, the symbols are stopped on a predetermined winning line in the game in which those awards are won. Can do. Therefore, it is not necessary to provide a stop data table dedicated to non-winning (the one having “a” at the end of the table number). Although the stop data table group TBL31 in this embodiment is divided according to each prize or loss, it is not always necessary to make such a division, and when the same stop data table is used, the award data table group TBL31 is not necessarily divided. Even if they are different, they can be used together.

  As described above, the validity determination data tables 101L to 103L shown in FIG. 21 have a 1-bit data structure of “0” and “1” similarly to the stop data table shown in FIG. And the validity determination data table indicate the same data, they can be shared. For this reason, conventionally, it has been necessary to prepare the stop data table and the validity determination data table separately, but the data amount can be reduced by sharing them. FIG. 32 shows a part of a plurality of shared data tables that share the stop data table having a 1-bit data structure of “0” and “1” stored in the ROM 104 and the validity determination data table. For example, the data table indicated by “No00” is “02H, 05H, 00H (hexadecimal)”, and is stored as a table referred to by the validity determination data table 102L. The data table indicated by “No02” is “02H, 21H, 11H (hexadecimal number)”, and is stored as a table to which the stop data tables 101 and 303 refer. The data table indicated by “No 04” is “04H, 51H, 11H (hexadecimal)”, and is stored as a table to which the stop data table 221 and the validity determination data table 201L refer. That is, the data tables shown in “No01”, “No02”, “No03”, “No05”, “No08”, “No10”, “No11”, and “No12” shown in FIG. The data tables indicated by “No00”, “No07”, “No08”, “No09”, and “No13” are used as validity determination data tables. The data tables indicated by “No 04” and “No 06” are used for both the stop data table and the validity determination data table. Thus, some of the plurality of shared data tables are shared by the stop data table and the validity determination data table.

  The code data such as “No00” and “No01” for specifying each data table of the plurality of data tables may be stored together. However, even if there is no code data, the data table to be selected can be selected. Can be identified. That is, since each data table is fixed data having a length of 3 bytes, when a plurality of shared data tables are sequentially stored from a predetermined address of the ROM 104, 3 is assigned to the number for specifying the data table from the predetermined address. The contents stored in the 3-byte storage area indicated by the address obtained by offsetting the value obtained by multiplication can be specified as data. That is, the control for selecting the stop data table and the validity determination data table may be managed by numbers. Therefore, the stop link table shown in FIG. 13 may store a number specifying the data table as shown in FIG. That is, “02” is stored as the replay stop data table 101, “03” is stored as the replay stop data table 102, and “11” is stored as the replay stop data table 103. Yes. In addition, the validity determination link table stores a number for identifying the validity determination data table as shown in FIG. That is, “00” is stored as the replay valid data table 101L, “07” is stored as the replay valid data table 102L, and “09” is stored as the replay valid data table 103L. Yes.

  Returning to FIG. First, the CPU 101 determines whether or not the re-game winning flag is set with reference to bit 0 of the winning information 2 data (S106a). If it is determined that the re-game winning flag is set, the re-game stop link table TBL21 is determined. Is selected (S106a1).

  Next, the CPU 101 refers to bit 3 of the winning information 2 data to determine whether or not the small role C winning flag is set (S106b). The link table TBL22 is selected (S106b1).

  Next, the CPU 101 refers to bit 2 of the winning information 2 data to determine whether or not the small role B winning flag is set (S106c). The link table TBL23 is selected (S106c1).

  Next, the CPU 101 refers to bit 1 of the winning information 2 data to determine whether or not the small role A winning flag is set (S106d). The link table TBL24 is selected (S106d1), and this process ends.

  Next, the CPU 101 refers to bit 3 of the winning information 1 data to determine whether or not the RB winning flag is set (S106e). If it is determined that the RB winning flag is set, the CPU 101 stores the RB stop link table TBL25. Selection is made (S106e1), and this processing is terminated.

  Next, the CPU 101 refers to bit 1 of the winning information 1 data to determine whether or not the BB2 winning flag is set (S106g). If it is determined that the BB2 winning flag is set, the CPU 101 stores the BB2 stop link table TBL26. Select (S106g1), and the process is terminated.

  Next, the CPU 101 refers to bit 0 of the winning information 1 data to determine whether or not the BB1 winning flag is set (S106h). If it is determined that the BB1 winning flag is set, the CPU 101 stores the BB1 stop link table TBL27. Selection is made (S106h1), and this processing is terminated.

  Finally, if one winning flag is not set, the CPU 101 selects the stop link table for losing TBL29 (S106p) and ends the process.

  FIG. 15 is an explanatory diagram showing a data structure of a stop data table for replaying used to stop the right reel R3 and displaying a plum symbol at the middle position. FIG. 15A shows the symbol arrangement of the right reel band. FIG. 15B shows the number of advance frames from “0” to “4” instructing to stop from the stop operation symbol position at the timing when the stop operation instruction signal 113c is detected to the number of symbols ahead. The stored conventional method is shown. In this method, the values “0” to “4” indicating the number of advance frames are stored in the RAM 105 by 3-bit information. Therefore, when storing stop data for 21 frames per reel, a storage amount of 3 × 21 = 63 bits (7 bytes) is required. That is, when the stop data table group TBL31 shown in FIG. 13 is configured, a large amount of storage is required. In this example, 1-bit information indicating “1” or “0” shown in FIG. 15C is stored instead of “0” to “4” indicating the conventional advance frame number. Therefore, as shown in FIG. 15D, the stop data for one reel can be 1 × 21 = 21 bits (3 bytes). This “1” or “0” is determined by determining whether the data bits (b7 to b0) corresponding to the symbol position nearest to the stop position where the stop operation instruction signal 113c is detected are “1” or “0”. When “1” is “1”, it indicates that the frame stops at the symbol position. When the data bit is “0”, it indicates that the number of bits up to the bit position indicating “1” is advanced and stopped. .

  In the case where the stop operation symbol number PN at the player's stop operation timing is “7”, for example, a value of “0” is acquired, and the closest “ The bit position storing “1” is searched to obtain the data bit “1” corresponding to the symbol number PN = 10. Next, the number of bits from the bit position corresponding to the symbol number PN = 7 to the bit position corresponding to the symbol number PN = 10 is obtained to obtain “3”. Therefore, when the symbol number PN = 7 is stopped, it is only necessary to advance three frames from the stop operation symbol number and display the plum symbol having the symbol number PN = 10 in the middle stage.

  FIG. 16 is an explanatory diagram showing a data structure of a stop data table used for stopping the right reel R3. 16A shows the symbol arrangement of the right reel band, and FIGS. 16B, 16C, and 16D show the replay stop data table TBL301, the small role B stop data table TBL321, and the stop for BB1, respectively. The data table TBL361 is shown. These stop data tables are “1” and “0” for instructing to stop from a symbol position (stop operation symbol position) immediately before the stop position where the stop operation instruction signal 113c is detected to a number of symbols ahead. "Data is stored. “1” means stop at the stop operation symbol position, and “0” means stop at the symbol position where the latest “1” is stored.

  The replay stop data table TBL301 can stop the plum symbol in the middle regardless of the symbol number (stop operation symbol number) of the stop operation symbol position. Also, in the small role B stop data table TBL321, the bell symbol can be stopped at the middle stage regardless of the stop operation symbol number. In this way, if five of the 21 symbols are arranged within an interval of 4 frames, the symbol can always be stopped at the middle stage regardless of the symbol number. Such a plum symbol and bell symbol are called 100% retracted symbols.

  On the other hand, in the BB1 stop data table TBL361, the red 7 symbols can be stopped in the middle only at 5 locations where the stop operation symbol numbers are “5” to “9” (winning pull-in range). Stop operation symbol numbers “19” to “1” (winning pull-in range) and “10” to “13” (winning pull-in range), “2” to “4” (winning pull-in range), “14” to “18” "(Winning pull-in range), the cherry symbol, the BAR symbol, and the white 7 symbol are stopped in the middle.

  For example, when the stop operation symbol number PN at the stop operation timing of the player is “7”, when the re-game stop data table TBL301 is selected, the bit information “0” is acquired, and the latest Advance to the plum symbol of symbol number PN = 10 where bit information “1” is stored, display three frames, and display “1” when the small data B stop data table TBL321 is selected. Then, the bell symbol of the symbol number PN = 7 is displayed in the middle without proceeding from the stop operation symbol number. When the BB1 stop data table TBL361 is selected, the bit information “0” is acquired, and two frames are advanced to the red 7 symbol of the symbol number PN = 9 in which the latest bit information “1” is stored. Display in the middle. Depending on the stop data table selected in this way, even if the same stop operation symbol number is used, the symbols to stop in the middle stage are different.

<5-5: Reel stop processing>
17 to 18 are flowcharts showing the contents of the reel stop process in step S109. In this reel stop process, the first stop and the second stop stop the reels according to the stop data in the stop data table, and the third stop may be awarded within the range of the stop operation symbol position 4 frames ahead of the stop operation timing. Depending on whether or not there is an operation stop control process for branching whether to stop the reel according to the stop data in the stop data table or to search the symbol stop position constituting the role and stop the reel including. In general, the former is called a table control method, and the latter is called control control. In the present embodiment, at the time of the last stop operation, the presence / absence of a winning possibility is determined, and the table control method and the control control method are switched based on the determination result. The details will be described below.

  First, the CPU 101 determines whether or not the first stop button stop operation has been performed based on the stop operation instruction signals 113a to 113c (S109a). In step S109a, when any one of the stop operation instruction signals 113a to 113c is detected, it is determined that the first stop button stop operation has been performed. In this case, a stop button number indicating the type of the stop button is acquired from the detected stop operation instruction signals 113a to 113c, and a stop operation symbol number immediately after the stop operation is acquired (S109b). Specifically, the stop button number and the stop operation symbol number at the timing are acquired by detecting stop operation instruction signals 113a to 113c that are output when the stop buttons 13a to 13c are pressed. In this example, stop button numbers “1”, “2”, and “3” are assigned to the stop buttons 13a, 13b, and 13c, respectively.

  Next, the CPU 101 limits the data group of the stop link table that can be used from the stop button number among the stop link tables based on the winning flag selected in the reel stop link table selection process of step S106 (S109c). Specifically, from the acquired stop button number, which data group from the stop link table (a) for the left reel R1, the stop link table (b) for the middle reel R2, or the stop link table (c) for the right reel R3. Limit the use of

  Next, the CPU 101 sets the first validity determination data table to be analyzed (S109d). In this case, the CPU 101 refers to the stop link data selected in step S109c, limits the stop data table, specifies a plurality of validity determination data tables corresponding to the limited plurality of stop data tables, and specifies the specified plurality One validity judgment data table is set from among the validity judgment data tables. Thereafter, the CPU 101 performs data analysis processing (S109e). This data analysis process refers to the set validity determination data table and determines whether the determination data selected based on the stop operation symbol number is valid (valid table determination function) and the selected This is a process in which the function of acquiring the advance frame number from the stop data table (advance frame number acquisition function) is also used. Specifically, the processing performed as the valid table determination function is executed in step S109e and step S109n, and the processing performed as the advance frame number acquisition function is executed in step S109g, step S109q, and step S109x.

  FIG. 19 is a flowchart showing data analysis processing executed in step S109e, step S109n, step S109g, step S109q, and step S109x. The data to be analyzed in this data analysis process is the validity determination data table or the stop data table. When the data analysis process is set to the validity determination function, the data to be analyzed becomes the validity determination data table. In the case where the frame number acquisition function is performed, the data to be analyzed is a stop data table. The reason why two different functions can be executed as a common process in this way is that the data values stored in the table are both “1” and “0” information. Therefore, when executing the process, it is possible to perform the process without distinguishing which data is handled. As the output of this process, in the case of the advanced frame number acquisition function, values of “0” to “4” (maximum value) are acquired, and the acquired value becomes the advanced frame number. In the case of the valid table determination function, values “0” to “20” (maximum value) are acquired. In the case of this valid table determination function, when the value “0” is obtained, the corresponding stop data table is judged to be valid, and when the value other than “0” is obtained, the corresponding stop data table is invalid. to decide.

  First, the CPU 101 sets a validity determination data table or a stop data table as data to be analyzed, examines bit information corresponding to the stop operation symbol number, and if the bit information is “1”, it is “0”. A value is acquired, and when the bit information is “0”, the bit position corresponding to the symbol number where the bit information is “1” in the direction of adding the symbol number is searched (S200). When the symbol number to be searched exceeds “21”, the symbol number is returned to “1”. Thus, the search is performed, and the number of bits up to the bit position corresponding to the symbol number from which the value of the bit information “1” is acquired is set as the acquired value of the processing (S201).

  That is, when the stop operation symbol number is given, the CPU 101 refers to a specific table, acquires data corresponding to the stop operation symbol number, and the data value is predetermined between “1” and “0”. On the other hand (in this example, “0”), the data stored in the table in the direction in which the stop operation symbol number at the reference position (middle stage of the display window) changes as the variable display progresses is the data value. Until the value changes (until “1” in this example), and the number of retrieved data is used as an acquired value of the process. In order to make this data analysis process common, the number of searched data until the most recent data value changes is included as the acquired value of the process, but it is included in the stop operation symbol number of the data to be analyzed The process up to the corresponding position search process may be a common process, and the subsequent search process for the number of data at the change point of the most recent data value may be a separate process.

  FIG. 21 shows replay validity determination data tables TBL101L to 103L. FIG. 21A shows the symbol arrangement of the left reel band. A table TBL101L shown in FIG. 21B is a table describing data that is valid when a stop data table for stopping the plum symbol in the middle stage is selected. A table TBL102L shown in FIG. 21C is a table that describes data that is valid when a stop data table for stopping the plum symbol in the upper stage is selected. A table TBL103L shown in FIG. 21D is a table that describes data that is valid when selecting a stop data table for stopping the plum symbol in the lower stage. In the validity determination data tables TBL101L to 103L, “1” or “0” is stored as bit information indicating whether or not the validity determination data table is valid, and when the bit information is “1”, When “valid” and the bit information is “0”, “invalid” is indicated. In this example, one of the validity determination data tables TBL101L to 103L is always stored as “valid” according to the symbol number. Specifically, when the symbol number PN = 3, 4, 7, 13, 14, 15, 17, 19, and 20, the validity determination data table TBL101L is valid. In the case of symbol numbers PN = 9, 11, and 18, the validity determination data table TBL102L is valid. When the symbol numbers PN = 1, 2, 5, 6, 8, 10, 12, 16, and 21, the validity determination data table TBL103L is valid. In this way, when there are a plurality of validity determination data tables, it is determined using analysis data processing which validity determination data table is selected as valid.

  In this example, the validity determination data tables TBL101L to 103L stop the plum symbols at the middle, upper and lower stages, respectively, when the validity determination data table TBL101L is valid, stop data that stops the plum at the middle stage. When the table TBL101 is selected and the validity determination data table TBL102L is valid, the stop data table TBL102 for stopping the plum in the upper stage is selected, and when the validity determination data table TBL103L is valid, the plum is stopped in the lower stage. This is because the stop data table TBL103 is selected. Therefore, in the case of the stop operation symbol number PN = 3, 4, 7, 13, 14, 15, 17, 19, and 20 where the validity determination data table TBL101L is selected, the plum symbol is displayed in the middle stage, and the validity determination data table TBL102L When the stop operation symbol number PN = 9, 11, and 18 is selected, the plum symbol is displayed in the upper row, and the validity determination data table TBL103L is selected. The stop operation symbol number PN = 1, 2, 5, 6, 8 In the case of 10, 12, 16 and 21, the plum symbol is displayed in the lower part. In this example, the three validity determination data tables TBL101L to 103L are respectively defined as a middle stage stop, an upper stage stop, and a lower stage stop. However, it is not always necessary to correspond to the stop position, and the stop position for stopping the symbol is set. It is only necessary to provide a plurality for the purpose of dispersion.

  Returning to FIG. First, the CPU 101 sets the validity determination data table TBL101L as a data analysis target (S109d), and executes a data analysis process (S109e). In the case where the stop operation symbol number PN at the player's stop operation timing is “6”, for example, this data analysis process allows the closest bit information “1” on the upstream side of the symbol (the side with the larger symbol number PN). As a result of searching the bit position storing “”, the bit information “1” of the symbol number PN = 7 is obtained, and “1” which is the number of bits from the symbol number PN = 6 to PN = 7 is obtained, It is determined whether the stop link data 101L is valid data (S109e1). In step 109e1, since it is determined that the acquired value is valid when it is “0”, the process proceeds to step S109d2, the table TBL102L is set as the next validity determining data table, and the data analysis process is executed again (S109e). As a result of searching for the bit position storing the nearest bit information “1” on the upstream side of the symbol (the side with the larger symbol number PN) by this data analysis processing, the bit information “1” of symbol number PN = 9 is retrieved. Then, “3”, which is the number of bits from symbol number PN = 6 to PN = 9, is acquired, and it is determined whether the stop link data 102L is valid data (S109e1). Similarly, in step 109e1, since it is determined as valid when the acquired value is “0”, the process proceeds to step S109d2 again, the table TBL103L is set as the next validity determination data table, and the data analysis process is executed again (step 109e1). S109e). As a result of searching for the bit position storing the nearest bit information “1” on the upstream side of the symbol (the side with the larger symbol number PN), the data analysis process obtains “1” of symbol number PN = 6. Then, “0”, which is the number of bits from symbol number PN = 6 to PN = 6, is acquired, and it is determined whether stop link data 103L is valid data (S109e1). Similarly, in step 109e1, since it is determined that the acquired value is “0”, the stop link data 103L is set as valid stop link data.

  In this example, since the stop data tables corresponding to the validity determination data tables TBL101L to 103L are associated with the TBLs 101 to 103, the stop table obtained by the analysis result is set as the data analysis target for the TBL 103, and the data analysis process is performed. This is executed (S109g), the value acquired as a result of this analysis process is set as the advance frame number, and the reel that has been stopped is stopped based on the advance frame number (S109h).

  Next, the CPU 101 determines whether or not a second stop button stop operation has been performed based on the stop operation instruction signals 113a to 113c (S109j). In step S109j, when any one of the stop operation instruction signals 113a to 113c other than those already detected is detected, it is determined that the stop operation of the second stop button has been performed. In this case, a stop button number indicating the type of the stop button is acquired from the detected stop operation instruction signals 113a to 113c, and a stop operation symbol number immediately after the stop operation is acquired (S109k).

  Thereafter, data analysis is performed in the same manner as in the first stop process to obtain valid stop link data (S109m to S109n2). Next, the CPU 101 sets the stop table obtained from the analysis result as a data analysis target and executes the data analysis processing (S109q), sets the value acquired by the result of this analysis processing as the advance frame number, and advances. The reel that has been stopped is stopped based on the number of frames (S109r).

  Next, the CPU 101 determines whether or not the third stop button stop operation has been performed based on the stop operation instruction signals 113a to 113c (S109s). In step S109s, when any one of the stop operation instruction signals 113a to 113c other than those already detected is detected, it is determined that the stop operation of the third stop button has been performed. In this case, a stop button number indicating the type of the stop button is acquired from the detected stop operation instruction signals 113a to 113c, and a stop operation symbol number immediately after the stop operation is acquired (S109t).

  Next, the CPU 101 performs a winning determination process to be described later (S109u), determines whether or not there is a possibility of winning within the range of four frames ahead of the stop operation symbol position of the operation timing, and whether or not there is a possibility of winning Thus, the migration process is branched (S109v). If it is determined that there is a possibility of winning, the symbol position to be won is set as the number of frames to advance (S109y), and the reels are stopped so as to align the symbols related to the winning prize in the internal lottery (S109z). In this case, the reel stop control is not a stop data table, but is a control control in which a stop position is designated by judging a preceding symbol. That is, control control is used when winning.

  On the other hand, when it is determined in step S109v that there is no possibility of winning, it is set so that no combination is configured on the winning line regardless of the result of stopping two reels that have already stopped. The stop data table for the third stop shown in FIG. 14B is selected (S109w), and the data analysis process is executed (S109x). The value acquired in this analysis process is set as the advance frame number, and the reel that has been stopped is stopped based on the advance frame number (S109z). The stop data table used in step S109w is a non-winning stop data table. Even if the result of the internal lottery is lost due to the common process, steps S109u and S109v are executed. However, since the winning combination corresponding to the winning prize does not enter the tempering state, the process of step S109y is executed. There is no. Therefore, in the case of loss after step S109t, the process may proceed to step S109w.

  FIG. 20 is a flowchart showing the contents of the winning determination table creation processing in steps S109u and S110a. This winning determination table creation process creates a winning determination table for a plurality of stop position candidates (five) in order to determine the stop position of the third reel to be stopped. Create a judgment table. First, the CPU 101 determines whether all reels are stopped (S210), determines that it is not a case where all reels are stopped, sets the maximum advance frame number to 4 (S211), and proceeds to step S214.

  On the other hand, when it is determined in step S210 that all reels have stopped, the stop operation symbol number is acquired (S212). However, since all the reels R1 to R3 have stopped, the symbol number of the right reel that has stopped. And Subsequently, the maximum advance frame number is set to 0 (S213), and the process proceeds to step S214.

  In step S214, the stop operation symbol number acquired in step S109t or S212 is set as the temporary symbol number. The temporary symbol number is used to create a winning determination table. Next, the CPU 101 sets the number of provisional advance frames associated with the winning determination table to be created to 0 (S215). Thereafter, the winning determination table is created by the number obtained by adding 1 to the maximum advance frame number. Specifically, one winning determination table is created in association with the provisional advance frame number (S216), and it is determined whether or not the provisional advance frame number matches the maximum advance frame number (S217). In the case of a failure, the temporary symbol number and the temporary advance frame number are incremented (S218), and the process returns to step S216. If the provisionally advanced frame number matches the maximum advanced frame number, the winning determination table creation process is terminated.

  In step S216, first, one winning determination table is secured in the RAM 105 in association with the provisional advance frame number. The winning determination table secured here includes L1 to L5 lines corresponding to the winning lines L1 to L5, and each of the L1 to L5 lines is formed by arranging three storage areas for holding data. That is, the winning determination table has 5 × 3 = 15 storage areas. Next, for each of the winning lines L1 to L5, the CPU 101 displays the symbol number of the symbol displayed on the winning line by the left reel R1, the symbol number of the symbol displayed on the winning line by the middle reel R2, and the temporary symbol number. When the right reel R3 is stopped so that the symbol is positioned on the winning line L1, the symbol code PC of the symbol displayed on the winning line by the right reel R3 is applied to the corresponding line in the secured winning determination table. The process of writing in order is performed.

  This process will be specifically described. However, the maximum advance frame number is assumed to be four. That is, step S216 is repeated only five times. Further, it is assumed that three game medals are inserted and all of the five pay lines L1 to L5 are activated. Further, it is assumed that the winning flag for the BB1 prize is set and the symbol shown in FIG. 22 is displayed on the reel window 20. That is, a bell symbol (symbol number PN = 12) is displayed on the upper stage of the left reel R1, a red 7 symbol (symbol number PN = 11) is displayed on the middle stage, and a watermelon symbol (symbol number PN = 10) is displayed on the lower stage. Plum symbols (symbol number PN = 11) are displayed in the upper row, red symbols (symbol number PN = 10) are displayed in the middle row, bell symbols (symbol number PN = 9) are displayed in the lower row, and plum symbols (symbol number PN = 9) are displayed in the lower row. It is assumed that a red 7 symbol (symbol number PN = 9) is displayed in the middle row, and a watermelon symbol (symbol number PN = 8) is displayed in the lower row. Therefore, in step S214, the temporary symbol number PN = 9.

  In the first step S216, since the temporary symbol number PN = 9, the right reel R3 is displayed when the right reel R3 is stopped so that the symbol of the temporary symbol number PN = 9 is positioned on the winning line L1. As shown in FIG. 22, the symbols are symbols with symbol numbers PN = 8-10. Therefore, the symbol codes PC indicating the symbol combinations on the winning line L1 are “01”, “01”, and “01”. Similarly, the symbol codes PC indicating the symbol combinations on the winning lines L2 to L5 are “05” “07” “07”, “04” “05” “04”, “05” “01” “04”. ”And“ 04 ”“ 01 ”“ 07 ”. The CPU 101 secures a winning determination table TBL41 in association with the provisional advance frame count = 0, and writes the symbol code PC in the winning determination table TBL41. As a result, a winning determination table TBL41 having the contents shown in FIG. 23 is created.

  In the second step S216, since the temporary symbol number PN = 10 is obtained by the increment of step S218, when the right reel R3 is stopped so that the symbol of the temporary symbol number PN = 10 is positioned on the winning line L1. The symbols displayed by the right reel R3 are symbols having symbol numbers PN = 9 to 11 as shown in FIG. Therefore, the symbol codes PC indicating the symbol combinations on the winning line L1 are “01”, “01”, and “07”. Similarly, the symbol codes PC indicating the symbol combinations on the winning lines L2 to L5 are “05” “07” “05”, “04” “05” “01”, “05” “01” “01”. ”And“ 04 ”“ 01 ”“ 05 ”. The CPU 101 secures a winning determination table TBL42 in association with the provisional advance frame number = 1, and writes the symbol code PC in the winning determination table TBL42. As a result, a winning determination table TBL42 having the contents shown in FIG. 23 is created.

  Similarly to the above, in the third step S216, a winning determination table TBL43 having contents corresponding to the temporary symbol number PN = 11 is created in association with the temporary advance frame number = 2, and in the fourth step S216, the temporary symbol number PN. = 12 is created in association with the provisional advance frame number = 3, and the winning decision table TBL44 with the content corresponding to the temporary symbol number PN = 13 is provisionally advanced in step S216. Created in association with number = 4.

  In the above-described step S109y, the winning determination table TBL41 in which the winning combination is established is searched from the winning determination tables TBL41 to TBL45 created in this way. In this search, a winning combination data table TBL51 shown in FIG. 24 is used. The winning combination data table TBL51 shows, for each award, a combination of symbols constituting a combination related to the award in the arrangement of the symbol codes PC, and the arrangement order matches the arrangement order of the symbol codes PC in the winning determination table. ing. The arrangement of the symbol code PCs related to the small role C prize in the winning combination data table TBL51 is “06”, “FF”, and “FF”, but this “FF” means that any symbol may be used. .

  In the above search, the CPU 101 sequentially determines a winning determination having a line in which the arrangement (set) of the symbol codes PC matches the arrangement (set) of any of the symbol codes PC in the winning combination data table TBL51 in the order from the winning determination table TBL41. Until the table is found, it is determined whether or not the winning determination table has such a line. It is determined in the winning combination data table TBL51 whether or not the arrangement of the symbol codes PC in the line of the winning determination table matches any of the symbol codes PC in the winning combination data table TBL51. This is done by comparing the symbol code PC. However, in this comparison, “FF” is treated as a symbol code PC that matches any symbol code PC.

  Since the winning determination table TBL41 has a line in which the arrangement of the symbol codes PC matches any of the symbol codes PC in the winning combination data table TBL51, the CPU 101 adopts the winning determination table TBL41 as a search result. Then, the temporary advance frame number = 0 associated with the winning determination table TBL41 is acquired as the advance frame number.

  In the specific example described above, the symbol code PC is written in all the L1 to L5 lines of the winning determination table because all the winning lines L1 to L5 are activated. When only the winning line L1 is activated or only the winning lines L1 to L3 are activated, the CPU 101 displays “ 00 "is written. Note that the winning determination table may be created so as to have only lines corresponding to the activated winning lines. That is, when only the winning line L1 is enabled, a winning determination table having only the L1 line is created, and when only the winning lines L1 to L3 are enabled, the L1 line, the L2 line, and the L3 line are created. It is also possible to create a winning determination table having only

<5-6: Winning determination process>
FIG. 25 is a flowchart showing the contents of the winning determination process in step S110. In this winning determination process, the combination of symbols arranged on the winning line after the reels are stopped is checked to determine whether or not a winning is achieved. If it is determined that a prize has been won, a process for starting another type of game is performed if the prize is a start prize, and a payout is awarded if the prize is a small prize.

  First, the CPU 101 creates the aforementioned winning determination table from the stop operation symbol numbers of all reels R1 to R3 (S110a). In the winning determination table creation process, a winning determination table TBL41 is created. For example, when the symbol shown in FIG. 22 is displayed on the reel window 20, a winning determination table TBL41 having the contents shown in FIG. 23 is created. Next, the CPU 101 performs a winning determination with reference to the winning determination table created in step S110a (S110b).

  Next, the CPU 101 determines whether or not a re-game prize has been won (S110c). If it is determined that a win has been won, the re-game win flag of bit 0 of the winning information 2 data is cleared (S110c1). Subsequently, an automatic bet process is performed (S100a in FIG. 8), and the process returns to step S101.

  Next, the CPU 101 determines whether or not a small role C prize has been won (S110d). If it is determined that a prize has been won, a payout process for two medals is performed (S110d1). Subsequently, it is determined whether or not the small role B prize has been won (S110e). If it is determined that the prize has been won, a payout process for 10 medals is performed (S110e1). Subsequently, it is determined whether or not a small role A prize has been won (S110f). If it is determined that a prize has been won, a payout process for 15 medals is performed (S110f1). In these payout giving processes, a payout credit process is performed in which the number of payouts is added to the credit up to the credit upper limit value (50), and a payout for paying out medals from the medal payout device to the medal tray 40 for the portion exceeding the credit upper limit value. Switch to processing.

  Next, the CPU 101 determines whether or not an RB prize has been won (S110g). If it is determined that a prize has been won, an RB game flag in bit 3 of the game type data is set to "1" (S110g1). . Subsequently, the maximum small part winning number (remaining winning number) in the RB game is set to 8, and the maximum game number (remaining maximum game number) is set to 12 (S110g2).

  Next, the CPU 101 determines whether or not the BB1 award to the BB2 award has been won (S110h). 1 ”(S110h1), and the acquired number counter is cleared (S110h2).

  Next, the CPU 101 further sets the RB game flag of bit 3 of the game type data to “1” (S110h3). Subsequently, the maximum small part winning number (remaining winning number) in the RB game is set to 8, and the maximum game number (remaining maximum game number) is set to 12 (S110h4). By the processing of steps S110h3 and S110h4, the RB game can be started from the first game of the BB game. If steps S110h3 to S110h4 are omitted, the RB game is not executed immediately after the start of the BB game, and the RB game can be started when winning the RB award. Thereafter, this process is terminated.

<5-7: Game end determination process>
26 to 27 are flowcharts showing the contents of the game end determination process in step S111. In this game end determination process, it is determined whether or not the end condition is satisfied in the game for which the end condition is set.

  First, the CPU 101 refers to bit 3 of the game type data to determine whether or not it is an RB game (S111a), and if it is determined that the RB game is not being performed, the process proceeds to step S111h.

  On the other hand, if it is determined in step S111a that the RB game is in progress, it is determined whether or not a prize has been awarded by winning the small role prize in this game (S111b). When a prize is awarded after winning the small role award, the remaining small role winning number is subtracted (S111c), and then it is determined whether the remaining small role winning number has reached 0 (S111d). If it is determined that the number of small part winnings has reached 0, the RB game flag in bit 3 of the game type data is cleared (S111g).

  On the other hand, if it is determined in step S111d that there is a remaining small role winning number, the remaining winning number is displayed on the acquired number display 23b, and the remaining game number is subtracted (S111e). Subsequently, it is determined whether or not the remaining number of games has reached 0 (S111f). If it is determined that the remaining number of games has reached 0, the RB game flag is cleared (S111g), and there is a remaining number of games. Is determined, the remaining number of games is displayed on the acquired number display 23b.

  Next, the CPU 101 refers to bits 0 to 1 of the game type data to determine whether or not the BB game is in progress (S111h), and when determining that the BB game is not in progress, the CPU 101 proceeds to step S111q.

  On the other hand, if it is determined in step S111h that the BB game is in progress, it is determined whether or not a small role prize is won and a dividend is awarded in this game (S111j). When the small prize is awarded and a payout is awarded, the payout is added to the acquired number counter value (S111k), and the acquired number is displayed on the acquired number display 23b (S111m).

  Next, the CPU 101 compares the acquired number counter value with the acquired number upper limit determination value determined in each BB game (S111n). The acquired number upper limit determination value is a value that is 15 smaller than the acquired number upper limit value that must not be exceeded during the game, determined in each BB game. If the acquired number upper limit determination value is exceeded in step S111n, the BB game flag and the RB game flag (bits 0 to 3 of the game type data) are cleared (S111p).

  Next, the CPU 101 refers to bits 0 to 3 of the game type data to determine whether the BB game is in progress and not in the RB game (S111q), and whether the BB game is in progress or the BB game is in progress. If it is determined that the game is in progress, the process is terminated.

  On the other hand, if it is determined in step S111q that the game is in the BB game but is not in the RB game, the RB game flag in bit 3 of the game type data is set to “1” again (S111r), and then in the RB game. The maximum small role winning number (remaining winning number) is set to 8 and the maximum game number (remaining maximum game number) is set to 12 (S111s). Through the processing of steps S111r and S111s, in the BB game, a new next RB game is started from the next game after one RB game is completed, and the RB game is continuously executed. If steps S111r to S111s are omitted, the RB game is not continuously executed, and the RB game can be started when the RB prize is won. The game that is in the BB game but not in the RB game is a game in which one RB game is completed by satisfying the end condition of the maximum number of small winnings or the maximum number of games in the game, as described above. The game in which the RB game flag is cleared in step S111g. Therefore, in this game, the RB game flag is once cleared in step S111g, and the RB game flag is set again in step S111r. Since the slot machine 1 outputs a game type signal synchronized with the RB game flag or the BB game flag to the hall computer connected to the outside, this RB game segment is clearly defined. The flag processing is performed.

<5-8: Winning flag clear process>
FIG. 28 is a flowchart showing the contents of the winning flag clear process in step S112. In this winning flag clearing process, the winning flag set by internal lottery or the like during one game is cleared at the end of one game based on the type of winning flag and the result of the game, or carried over to the next game without being cleared. Do things.

  First, the CPU 101 clears the winning information 2 data in order to clear the replay winning flag, the small role A winning flag, the small role B winning flag and the small role C winning flag regardless of winning, in one game (S112a).

  Next, the CPU 101 determines whether or not the RB winning flag is set with reference to bit 3 of the winning information 1 data (S112b). If it is determined that the flag is set, the CPU 101 further determines the RB prize. It is determined whether or not a prize has been won (S112c). If it is determined that the RB combination has been established and the prize has been won, the RB winning flag is cleared (S112d). If it is determined in step S112c that the game has not been won, the RB internal game flag in bit 7 of the game type data is set to “1” (S112e), and the RB internal game is set from the next game.

  Next, the CPU 101 refers to bit 1 of the winning information 1 data to determine whether or not the BB2 winning flag is set (S112k). If it is determined that the flag is set, the CPU 101 further determines the BB2 award. It is determined whether or not a prize has been won (S112m). If it is determined that the BB2 combination has been established and the prize has been won, the BB2 winning flag is cleared (S112n) and the process is terminated. If it is determined in step S112m that the game has not been won, the BB internal game flag in bit 6 of the game type data is set to “1” (S112p), and the BB internal game is set from the next game.

  Next, the CPU 101 refers to bit 0 of the winning information 1 data to determine whether or not the BB1 winning flag is set (S112q). If it is determined that the flag is set, the CPU 101 further determines the BB1 prize. It is determined whether or not a prize has been won (S112r). If it is determined that the BB1 combination has been established and the prize has been won, the BB1 winning flag is cleared (S112s), and the process ends. If it is determined in step S112r that the game has not been won, the BB internal game flag in bit 6 of the game type data is set to “1” (S112t), the next game is changed to the BB internal game, and this process is terminated. .

<Summary>
According to the above-described embodiment, as shown in FIG. 31, in the first stop and the second stop, an effective stop table is determined as a selection candidate using the validity determination data table, and one stop table is selected from among the stop tables. Selected. In the last stop operation, it is determined whether a winning or non-winning is made, and the control control and the table control are switched according to the determination result. If all stop control is executed by control control, the program becomes complicated and the processing load increases. However, if the game is not won as in this embodiment, the processing load of the CPU 101 is reduced by switching to table control. Can be reduced.

  In the above-described embodiment, the control control and the 0/1 table control are switched depending on the possibility of winning in the final stop operation. However, the present invention is not limited to this, and the final stop operation is performed. May be executed only by the 0/1 table control. In this case, the 0/1 table control is executed even when there is a possibility of winning. However, it is preferable to switch one or a plurality of stop tables depending on the possibility of winning. In other words, if there is a possibility of winning, that is, if the symbols that make up the winning prize in the internal lottery are within the range of the maximum number of draws from the win line, use the stop table for winning and use the maximum draw number If it is not within the range, a non-winning stop table may be used. Furthermore, in the above-described embodiment, the 0/1 table control is scheduled in each of the first stop operation from the beginning. However, the frame number table control may be adopted by proceeding to some of them.

  In the above-described embodiment, the determination data stored in the validity determination table is such that the data value “1” indicating validity is stored in one stop table so that one can be uniquely determined from a plurality of stop tables. However, the present invention is not limited to this, and the plurality of stop tables are determined to be valid by searching the plurality of validity determination data tables based on the stop operation symbol number. Determination data may be set. In this case, a plurality of stop tables are candidates for selection. The CPU 101 may select one from the selection candidates. In this case, the CPU 101 may select the stop positions of the symbols to be drawn in an order according to a predetermined rule such as upper stage → middle stage → lower stage, or may be selected by lottery.
