  However, in the above-mentioned gaming machine, the internal lottery table is determined according to the type of bonus combination won, so that the winning probability of the small combination / replay during the bonus game can be changed according to the player's own action. I could not. Also, since the symbol corresponding to the bonus combination is displayed when shifting to the bonus game, the player knows which bonus game state to shift to among the multiple types of bonus game states, I couldn't provide games that kept my interest. For this reason, the above-described conventional technique has a problem that the game performance during the bonus game becomes poor.

  Therefore, the present invention has been made to solve the above-described problems of the prior art, and an object thereof is to improve the game performance during the bonus game.

  The present invention has been made to solve such a problem, and a plurality of reels each having a plurality of symbols arranged on each peripheral surface, and a part of the plurality of symbols arranged on the peripheral surface of the reel. A symbol display means (for example, reels 3L, 3C, and 3R described later, display windows 21L, 21C, and 21R described later) having a symbol display area for displaying and a predetermined start condition is satisfied, By rotating the reel, a symbol changing means (for example, a main control circuit 71 described later) that changes the symbol displayed in the symbol display area, a general gaming state (for example, a RT1 gaming state described later), A plurality of types of high-probability re-gaming states (for example, an RT2 gaming state or RT3 gaming state described later) having a higher probability of winning a re-gamer than the general gaming state are advantageous to the player compared to the general gaming state. Game An internal lottery table provided corresponding to a plurality of gaming states including at least a bonus gaming state (for example, a BB gaming state or an MB gaming state described later) and a gaming state to be switched with a predetermined condition as a trigger An internal state for determining an internal winning combination from a plurality of combinations by referring to a game state switching means (for example, a main control circuit 71 described later) and an internal lottery table corresponding to the current gaming state and the number of inserted game media. A plurality of stop operation means (stop buttons 7L, 7C, etc.) provided corresponding to each of the winning combination determining means (for example, a main control circuit 71 described later) and the plurality of symbol display means, respectively, for accepting a player's stop operation. 7R), a stop operation information notifying means (sub control circuit 72) for notifying information of a stop operation advantageous to the player, and the stop operation means being operated by the player. And a stop command means (stop switch 7S) for outputting a stop command signal for commanding the stop of the symbol to be variably displayed on the symbol display means corresponding to the operated stop operation means, and the stop command signal is output. In response to this, the reel stop control means (for example, a main control circuit 71 described later) for stopping the fluctuation of the symbol displayed in the symbol display area by stopping the rotation of the reel, and the reel Winning determination means (for example, a main control circuit 71 to be described later) for determining whether or not the internal winning combination determined by the internal winning combination determining means has won when the change of the symbol is stopped by the stop control means; A profit granting means (for example, a main control circuit 71 described later) for giving a profit according to a combination of symbols determined to have won the internal winning combination by the winning determination means; The combination of symbols corresponding to the bonus combination is stopped and displayed by the symbol display means on condition that the bonus combination that triggers switching to the bonus game state is determined as an internal winning combination by the internal winning combination determination means. Until there is a carry-over means (for example, a main control circuit 71 to be described later) carrying over the bonus combination as the internal winning combination and a plurality of symbols corresponding to the internal winning combination within the pull-in range, A winning combination, a game medium winning combination relating to the provision of the game medium, and a pulling-in control means (for example, a main control circuit 71 described later) for controlling the drawing so as to pull in the winning combination in order. The first bonus combination that triggers switching to the first bonus gaming state (for example, BB1 gaming state and BB2 gaming state described later) and the second bonus game state An internal lottery corresponding to the first bonus gaming state in the first bonus gaming state, having at least a second bonus combination (for example, an MB gaming state to be described later) that triggers switching to the eggplant gaming state. An internal winning combination is determined by referring to the table, and in the second bonus game state, only the re-game player is lottery with reference to the internal lottery table corresponding to the gaming state at the time of the second bonus game operation. Regardless of the determination result of the internal winning combination determining means, the game medium winning combination is determined as an internal winning combination, and the internal lottery table corresponding to the high-probability re-playing state corresponds to the symbol corresponding to the second bonus combination. According to the number of game media inserted when the combination is stopped and displayed by the symbol display means, the winning probability of the re-gamer is set differently, The part winning combination determining means refers to the internal lottery table corresponding to the number of game media inserted when the combination of symbols corresponding to the second bonus combination is stopped and displayed by the symbol display means, It is characterized in that lottery of the re-game player is performed during the second bonus game.

  Further, according to the present invention, as the high-probability replaying state, a first high-probability replaying state (for example, which will be described later) has a higher probability of winning a re-gamer as compared to the general gaming state (for example, the RT1 gaming state described later). RT2 gaming state) and a second high-probability replaying state (for example, RT3 gaming state described later) which is a more advantageous gaming state for the player compared to the first high-probability replaying state. The internal lottery table corresponding to the first high-probability re-playing state is such that the game medium inserted when the symbol combination corresponding to the second bonus combination is stopped and displayed by the symbol display means is the first. The re-game during the second bonus game is more when the number of game media is the second number (for example, two inserted numbers) than when the number is the number of inserted games (for example, three inserted sheets). The winning probability of the role is set high, The internal lottery table corresponding to the second high-probability replay state has the number of game media inserted when the symbol combination corresponding to the second bonus combination is stopped and displayed by the symbol display means. The winning probability of the re-gamer in the second bonus game is set higher when the number of game media is the first number than when the number is two. .

  Further, the present invention is a case where the second bonus combination is not won by the internal winning combination determination means in the general gaming state or the first high probability re-playing state, and the gaming state is When a combination of symbols corresponding to a special combination (for example, a watermelon to be described later) that is a trigger for changing is stopped and displayed by the symbol display means, the state shifts to the second high-probability re-playing state. In addition, in the first high probability replay state or the second high probability replay state, when a specific game medium winning combination (for example, a bell combination of 5 selections described later) is internally won, It further comprises a game state transition means for transitioning to a general game state on condition that a combination of symbols displayed when a specific game medium winning combination is missed is displayed.

  According to the present invention, when a combination of symbols corresponding to the second bonus combination (for example, MB combination to be described later) (for example, the later described MB symbol (red 7-red 7-BAR)) is stopped and displayed. With reference to the internal lottery table corresponding to the number of game media played, lottery of re-game players in the second bonus game is performed. For this reason, it is possible to create a state that is advantageous for the player by changing the number of inserted medals when the player prepares a combination of symbols corresponding to the second bonus combination. It is possible to improve.

  In addition, according to the present invention, there is only one type of symbol combination (for example, an MB symbol (red 7-red 7-BAR) to be described later) corresponding to a second bonus combination (for example, an MB symbol to be described later). Since the winning probability of the re-playing role can be changed according to the number of inserted symbols when the symbol corresponding to the second bonus role is displayed on the active line, a plurality of symbols corresponding to the second bonus role can be changed. As a result of diversifying the game characteristics during the bonus game without preparing the types, the game characteristics of the bonus game can be improved.

  In addition, according to the present invention, a first high-probability regame state (for example, RT2 described later) and a second high-probability regame state (for example, RT3 described later) are prepared as the high-probability replay state. . In the case of the first high-probability replaying state, the number of medals inserted when aligning the symbol combinations corresponding to the second bonus combination (for example, MB combination described later) is set to the first number (for example, 3) is set so that the winning probability of the replaying player (for example, replay (2) described later) in the second bonus game is increased, while the second high probability replaying state In this case, when the number of medals inserted when aligning the symbol combination corresponding to the second bonus combination (for example, MB combination described later) is set to the second number (for example, two), It is set so that the winning probability of a re-playing role (for example, replay (2) to be described later) during the bonus game is high. For this reason, at the time of MB game operation, the player guesses whether the gaming state is the first high-probability re-gaming state or the second high-probability re-playing state, and the second bonus is obtained by multiplying two by two. As a result of selecting whether to match the combination of symbols corresponding to the combination or to combine the combination of symbols corresponding to the second bonus combination with 3 cards, it is possible to provide a game that maintains the interest of the player and It is possible to improve playability.

  In addition, according to the present invention, the special bonus that triggers the transition of the gaming state when the second bonus combination (for example, an MB combination described later) is non-winning and corresponds to (for example, a watermelon described later) corresponds to When a combination of symbols to be stopped is displayed, the game state shifts to a game state advantageous to the player, and a specific game medium winning combination (for example, a bell combination of 5 selections to be described later) is missed. In this case, the gaming state shifts to a gaming state that is disadvantageous for the player. For this reason, when the combination of symbols corresponding to the above special combination is stopped and displayed, for example, when the second bonus combination and the special combination are simultaneously won and the special combination is stopped and displayed, the gaming state is If no change is made and only the special combination wins and the special combination is stopped and displayed, the gaming state is shifted. As a result, it is possible to make it difficult for the player to understand the current gaming state, and whether it is advantageous if the combination of symbols corresponding to the second bonus combination is multiplied by 2 or 3 is advantageous. The enjoyment of reasoning increases, it is possible to provide a game that maintains the interest of the player, and it is possible to improve the gameability of the bonus game.

  In addition, according to the present invention, it is possible to provide a gaming machine capable of improving the game performance during the bonus game.

  Embodiments of a gaming machine according to the present invention will be described below in detail with reference to the accompanying drawings.

[Functional flow of pachislot]
Embodiment 1 according to the gaming machine of the present invention will be described below with reference to the drawings. First, with reference to FIG. 1, the functional flow of the gaming machine (hereinafter referred to as “pachislot” as appropriate) 1 in the first embodiment will be described.

  When a medal is inserted by the player and the start lever 6 is operated, one value (hereinafter referred to as a random value) is extracted from random numbers in a predetermined numerical range (for example, 0 to 65535).

  The internal lottery means (main CPU 31 described later) performs lottery based on the extracted random number value and determines an internal winning combination. By determining the internal winning combination, a combination of symbols that permits display along a winning determination line described later is determined. The types of symbol combinations include those related to “winning” in which merits such as paying out medals, re-games, bonuses, etc. are given to players, and other so-called “loses”. Is provided.

  Subsequently, after the plurality of reels 3L, 3C, 3R are rotated, when the player presses the stop buttons 7L, 7C, 7R, reel stop control means (a motor drive circuit 39 described later, a stepping described later) The motors 49L, 49C, 49R) perform control to stop the rotation of the corresponding reel based on the internal winning combination and the timing when the stop button is pressed.

  Here, in the pachi-slot 1, basically, control is performed to stop the rotation of the corresponding reels 3L, 3C, 3R within a specified time (190 msec) from when the stop buttons 7L, 7C, 7R are pressed. In the present embodiment, the number of symbols that move with the rotation of the reels 3L, 3C, and 3R within the specified time is referred to as “the number of sliding symbols”, and the maximum number is defined as four symbols.

  The reel stop control means displays the symbol combination as much as possible along the winning determination line using the specified time when an internal winning combination permitting display of the symbol combination related to winning is determined. Then, the rotation of the reels 3L, 3C, 3R is stopped. On the other hand, for combinations of symbols that are not permitted to be displayed by the internal winning combination, the reels 3L, 3C, and 3R are used so as not to be displayed along the winning determination line using the specified time. Stop rotation.

  Thus, when the rotation of the plurality of reels 3L, 3C, 3R is all stopped, the winning determination means (for example, a main CPU 31 described later) indicates that the combination of symbols displayed along the winning determination line is related to winning. It is determined whether or not. When it is determined that the prize is related to a prize, a bonus such as a medal payout is given to the player. A series of flows as described above is performed as one game in the pachislot 1.

  Further, in the pachislot 1, in the above-described series of flows, video display performed by the liquid crystal display device 5, light output performed by various lamps, sound output performed by the speakers 9L and 9R, or a combination thereof is used. Various productions are performed.

  When the start lever 6 is operated by the player, an effect random number value (hereinafter referred to as effect random number value) is extracted separately from the random number value used for determining the internal winning combination. When the effect random number is extracted, the effect content determination means (sub control circuit 72 described later) determines by lottery what is to be executed this time from among a plurality of types of effect contents associated with the internal winning combination.

  When the production contents are determined, the production execution means (speakers 9L and 9R, the liquid crystal display device 5 described later), when the rotation of the reels 3L, 3C, and 3R is started, the rotation of the reels 3L, 3C, and 3R is started. When each is stopped, the execution of the performance is advanced in conjunction with each opportunity such as when the determination of the presence or absence of a prize is made. As described above, in the pachislot 1, the player has an opportunity to know or predict the determined internal winning combination (in other words, the combination of symbols to be aimed at) by executing the production contents associated with the internal winning combination. It is provided and the player's interest is improved.

[Game state transition]
Here, in the first embodiment, even if the extracted random number values are the same, if the gaming state is different, the determined internal winning combination may be different. In the first embodiment, RT (replay time) 1 gaming state, RT2 gaming state, BB (big bonus) internal hit state, BB RB gaming state, MB (middle bonus) gaming state gaming state are provided as gaming states. In the following, the RT1 gaming state may be referred to as a “general gaming state”.

  In the present embodiment, an internal lottery table (see FIG. 7 to be referred to later) corresponding to each gaming state is provided, and the probabilities that a privilege such as re-game operation is given to the player are different. That is, the probabilities that the replay (1) and the replay (2) in which a privilege such as re-game activation is given to the player are determined as internal winning combinations are different. When replay (1) is won internally, the winning operation flag of replay 1 (the combination of symbols is replay-replay-replay replay) is turned on. Also, when Replay (2) is won internally, Replay 1, Replay 2 (the combination of symbols is white 7-white 7-cherry) and Replay 3 (the combination of symbols is white 7-white 7-BAR) ) Winning operation flag is turned on.

  In the present embodiment, the probability that replay (one of replay (1) and replay (2)) is determined as an internal winning combination is set higher in the RT2 gaming state than in the RT1 gaming state. ing. That is, it can be said that the RT2 gaming state is a more advantageous gaming state for the player than the RT1 gaming state.

  As shown in FIG. 2, in the pachi-slot 1, after the end of the BB gaming state, the pachislot 1 transitions to the RT2 gaming state. Thereafter, in the RT2 gaming state, when the bell spilling eyes (Bell 1-Cherry-Replay or Bell 1-Cherry-Cherry) are displayed on the active line, the gaming state is shifted to RT1. Here, at the time of displaying the bell spilled eyes, the bell is displayed on the upper stage of the active line ("up / up / up" on the active line) and the bell spilled eyes (Bell 1-Cherry-Replay or Bell 1-Cherry) Cherry) is displayed at the same time on the lower right of the active line ("Up / Middle / Down" on the active line).

  Here, “bell removal” will be described in detail. First, when the bell wins internally and the push order is correct, the bell is displayed in the middle middle of the reel, and the bell is paid out most (the display is “up / middle”・ It is displayed in “below”). On the other hand, if the bell wins internally and the push order is incorrect (ie, if the bell is missed), the bell spills to the lower right ("up / middle / down” on the active line) (Bell 1-Cherry-Replay or Bell 1-Cherry-Cherry) is displayed, and a bell is displayed on the “upper / upper / upper” on the active line, and the payout of the bell is minimized. The state in which the bell is not paid out is called the state in which the bell is dropped (when the bell is dropped).

  Also, in the RT1 gaming state, when the combination of symbols corresponding to the watermelon role (watermelon-watermelon-watermelon) is displayed on the active line and the MB is non-winning, the gaming state is shifted to the RT2 gaming state. To do. For this reason, in the RT1 gaming state, even when the combination of symbols corresponding to the watermelon role (watermelon-watermelon-watermelon) is displayed on the active line, the MB is simultaneously won together with the watermelon. Does not enter the RT2 gaming state.

  In addition, when the MB is won internally and a combination of symbols corresponding to the MB (red 7-red 7-BAR) is displayed, the MB game is carried over by taking over the winning probability of the replay of RT1 and 2 at the time of MB game operation. Transition to the state. Here, in the MB gaming state, regardless of the result of the internal lottery, the bells 1 to 7 and the watermelon, which are small roles relating to the medal grant, are determined as the internal winning combination. That is, in the MB gaming state, the winning action flags of the bells 1 to 7 and the watermelon are turned on every game, and the internal lottery table is referred to determine whether or not only replay has been won internally.

  In the MB gaming state, a part of the symbol combination constituting the replays 2 and 3 (the left reel and the middle reel are white 7) and the bell 7 (white 7 bell) configured by the same symbol combination overlap. May win. The MB gaming state inherits the winning probability of replays RT1 to RT3 when the MB game is activated, and the white 7-bell display probability varies depending on the succeeding replay winning probability. When this white 7 bell is stopped and displayed, the number of ART games is added. For this reason, in the MB gaming state, the higher the winning probability of the re-gamer, the higher the possibility of increasing the number of ART games, and the gameability in the MB gaming state can be improved.

  Here, in the pachi-slot 1 according to the first embodiment, the internal lottery table (see FIG. 7) used during the MB game is selected according to the number of medals inserted when the MB symbol is displayed on the active line. . Specifically, the pachislot 1 has a gaming state (RT1 gaming state or RT2 gaming state) when the MB is won internally when the number of inserted symbols is two (two) and the MB symbols are aligned on the effective line. ) And an internal lottery table corresponding to the inserted number “2” is selected. Further, the pachislot 1 is an internal lottery table corresponding to the gaming state when the MB is won internally when the inserted number is 3 (3) and the MB symbols are aligned on the active line, and The internal lottery table corresponding to the inserted number “3” is selected.

  For example, referring to the example of FIG. 7, when the gaming state when the MB is won internally is the RT2 gaming state, the internal lottery table corresponding to the inserted number “2” has the inserted number “3”. The winning probability of replay is set higher than the internal lottery table corresponding to. In particular, since the internal lottery table corresponding to the inserted number “2” is set to have a high probability of winning the replay (2), the white 7-bell display probability is high, and the number of ART games is as described above. Since the possibility of being added increases, it is possible to create a state that is advantageous for the player by changing the number of inserted symbols when displaying the MB symbol on the active line. When the gaming state when the MB is won internally is the RT1 gaming state, the internal lottery table corresponding to the inserted number “3” is the internal lottery table corresponding to the inserted number “2”. However, the winning probability of replay is the same.

  In this way, the internal lottery table in the MB game is changed according to the number of inserted symbols when displaying the MB symbol on the active line, and the winning probability of the replay is changed, so that when the player aligns the MB symbol, By changing the number of inserted medals, it is possible to create a state that is advantageous to the player. Also, although there is only one type of MB symbol, the winning probability of replay can be changed according to the number of inserted symbols when displaying the MB symbol on the active line, so without preparing multiple types of MB symbols, As a result of diversifying the game characteristics of MB games, the game characteristics of MB games can be improved.

(Not shown).

[Design arrangement table]
The symbol arrangement table will be described with reference to FIG. The symbol arrangement table defines the position of each symbol in the rotation direction of each reel 3L, 3C, 3R and data (hereinafter, symbol code) specifying the type of symbol arranged at each position.

  In the symbol arrangement table, when the reel index is detected, each symbol position in the middle of the symbol display areas 21L, 21C, and 21R is set to “0”, and the symbols are arranged in the order of advance in the rotation direction of the reels 3L, 3C, and 3R. “0” to “20” are assigned to the positions of symbols, respectively. Therefore, by managing the number of symbols that have been rotated since the reel index was detected, by referring to the symbol arrangement table, the positions of symbols that exist mainly in the middle of the symbol display areas 21L, 21C, and 21R. And it is possible to always manage the kind of design.

[Design combination table]
The symbol combination table will be described with reference to FIG. In the present embodiment, when the symbol combination displayed by the reels 3L, 3C, and 3R along the winning line matches the symbol combination specified by the symbol combination table, it is determined that the winning combination is given. Benefits such as paying out a game, re-game operation, and bonus game operation are given to the player. FIG. 6 is a diagram showing a symbol combination table.

  The symbol combination table defines a symbol combination predetermined according to the type of privilege, a winning operation flag, a storage area type, and data indicating the number of payouts. The display combination is data for identifying a combination of symbols displayed along the winning line. The storage area type is data provided for the main CPU 31 to identify a display combination storage area (to be described later) that stores a winning action flag. The winning operation flag is represented as 1-byte data in which a unique symbol combination is assigned to each bit.

  Further, when a numerical value of 1 or more is determined as the payout number, medals are paid out. In this embodiment, medals are paid out when either the bell 1 to 7 or the watermelon is determined as the display combination. The number of payouts is defined according to the number of input, and is paid out up to a predetermined upper limit. If the symbol combination displayed along the winning line does not match any of the symbol combinations defined by the symbol combination table, it is a so-called “losing”.

  Further, when any one of the replays 1 to 3 is determined as the display combination, the replay operation is performed. When one of BB1, BB2, and MB is determined as the display combination, the bonus game is activated. The bonus game for BB1 and BB2 ends with a payout exceeding 300, and the bonus game for MB ends with a payout exceeding 120. After the end of the bonus game for BB1 and BB2, the game proceeds to the RT2 gaming state. In addition, when the watermelon is won internally and the watermelon is displayed on the active line, the game is shifted to the RT2 gaming state.

  Also, if the bells 1 to 6 are won internally and the order of the player's stop operation (pushing order) is not correct, the bell will be on the upper line of the active line ("Up / Up / Up" on the active line). At the same time, the bell spilled eyes (Bell 1-Cherry-Replay or Bell 1-Cherry-Cherry) are displayed on the lower right of the active line ("Up, Middle, Down" on the active line) Transition to the state. For example, when Bell 1 (ANY-Bell 1-ANY) wins internally, if the correct order is pressed, the design of Bell 1 is stopped and displayed in the middle of the middle reel, and the number of payouts is 3 x 3 lines. “9”. On the other hand, if Bell 1 (ANY-Bell 1-ANY) wins internally and the push order is incorrect, the bell spilled eyes will be displayed on the lower right and the bell will be displayed on the upper line of the active line. In the case of 3 sheets × 1 line, the payout number is “3”.

[Internal lottery table]
The internal lottery table will be described with reference to FIG. FIG. 7 shows an internal lottery table. The internal lottery table defines a data pointer and a lottery value according to the winning number. The data pointer is data acquired as a result of lottery performed with reference to the internal lottery table, and is data for designating an internal winning combination defined by an internal winning combination determination table described later. The data pointer is provided with a small role / replay data pointer and a bonus data pointer.

  In the present embodiment, the random number for lottery extracted from the predetermined numerical range “0 to 65535” is sequentially subtracted by the lottery value corresponding to each winning number, and whether or not the result of the subtraction becomes negative An internal lottery is performed by determining whether or not a so-called “digit” has occurred.

  Therefore, the larger the numerical value defined as the lottery value, the higher the probability that the data (that is, the data pointer) to which it is assigned will be determined. The winning probability of each winning number can be represented by “the lottery value corresponding to each winning number / the number of all random numbers that may be extracted (65536)”. Unless otherwise indicated in the figure, the lottery range is “0 to 65535”, that is, the probability denominator is “65536”.

  In this embodiment, depending on the current gaming state and the number of inserted medals, a plurality of types of internal lottery tables are selectively used to vary the type of internal winning combination determined and the winning probability. As a result, the player Undulations occur in the expectations of

  In the example of FIG. 7, an internal lottery table for game states corresponding to the number of inserted “2” and an internal lottery table for game state corresponding to the inserted number of “3” are provided. In addition, as the gaming state, “RT1” which is the RT1 gaming state, “RT2” which is the RT2 gaming state, “BB internal winning” which is a state where BB has won internally, or “RB gaming state which is during BB gaming” An internal lottery table corresponding to each “RB in each BB” is provided.

  As shown in FIG. 7, when the gaming state is the RT2 gaming state, the internal lottery table corresponding to the inserted number “2” is replayed (replayed) than the internal lottery table corresponding to the inserted number “3”. The winning probability of (1) and replay (2) is set high, and the internal lottery table corresponding to the inserted number “3” when the gaming state is the RT2 gaming state wins the replay (2). Since the probability is set high, the display probability of white 7 bell is increased, and as described above, there is a high possibility that the number of ART games will be added, so that the input when displaying the MB symbol on the active line It is possible to create a state that is advantageous to the player by changing the number of games, and if the gaming state is RT1 gaming state, BB internal winning, or RB in each BB, Be an internal lottery table corresponding to the number "2", even in the internal lottery table corresponding to the insertion number "3", winning probability of replay small role is the same.

[Internal winning combination determination table]
The internal winning combination determination table will be described with reference to FIGS. The internal winning combination determination table defines an internal winning combination in accordance with the data pointer. When the data pointer is determined, the internal winning combination is uniquely acquired.

  The internal winning combination is data for identifying a combination of symbols of each reel 3L, 3C, 3L that is permitted to be displayed along the winning line. When the data pointer is “0”, the content of the internal winning combination is “losing”, which indicates that display of any combination of symbols defined by the above-described symbol combination table is not permitted.

  FIG. 8 is an internal winning combination determination table for a small combination / replay, and defines an internal winning combination relating to the payout of medals and an internal winning combination relating to the replay operation. FIG. 9 is a bonus internal winning combination determination table, which defines internal winning combinations related to the operation of the bonus.

  For example, as shown in FIG. 8, when the replay (1) is determined as the internal winning combination, the winning operation flag of the replay 1 is turned on. When replay (2) is determined as an internal winning combination, the winning operation flags of replays 1 to 3 are turned on. For example, when the bell (5 choices) 1-2-3 (1) is determined as the internal winning combination, the winning operation flags of the bells 1 to 3 are turned on.

  In addition, the bell (5 choices) is awarded when the order of pushing is correct, and a bell spill is displayed when the order of pushing is incorrect. For example, when the bell (5 choices) 1-2-3 (1) is determined as the internal winning combination, if the stop operation is performed in the order of the left reel 3L → the middle reel 3C → the right reel 3R, the pushing order If the answer is correct, and the other stop operation is performed, the push order is incorrect.

  In addition, as shown in FIG. 9, the internal winning combination determination table for bonus includes BB1 (single), BB2 (single), MB (single), MB + watermelon, MB + all bells as internal winning combinations related to the operation of the bonus. It is prescribed.

[Internal lottery table determination table]
With reference to FIG. 10, the internal lottery table determination table used when the main CPU 31 determines the internal lottery table and the number of lotteries will be described.

  The internal lottery table determination table defines information indicating the internal lottery table and information indicating the number of lotteries corresponding to the gaming state.

  The gaming state is the type of internal winning combination that may be determined in the internal lottery process in which the internal winning combination is determined, the probability that the internal winning combination is determined in the internal lottery process, the maximum number of sliding symbols, and the bonus game It is in a state distinguished depending on whether or not the operation is being performed. The number of lotteries is the maximum number of times that the main CPU 31 subtracts a lottery value described later from one random number value (random number value for lottery) extracted by the sampling circuit 37.

  As shown in FIG. 10, in the MB gaming state, the winning operation flags of all the small roles are turned on, and the number of lotteries is “2”. Therefore, only the replay (1) and the replay (2) are subjected to internal lottery. Do. In the RB 1 and 2 gaming states, the number of lotteries is “1”, and “all bells” are internally won in each game.

[Pull-in priority table]
The priority table will be described with reference to FIG. In the present embodiment, when it is determined whether or not the symbol may be displayed for each symbol position during the rotation of the reels 3L, 3C, and 3R, the priority table has a symbol that can be displayed within the pull-in range. This is used when deciding which symbol should be preferentially drawn when there are multiple.

  The priority order table defines pull-in data indicating the pull-in priority order between symbol combinations related to the winning action flag (display combination). The pull-in priority data is information provided for the main CPU 31 to identify all the replays, all small combinations, BBs, and MBs corresponding to the pull-in priorities. Retraction basically stops the rotation of the reels 3L, 3C, 3R so that the symbols constituting the combination of symbols related to the internal winning combination are displayed along the winning line within the range of the maximum number of sliding symbols. Say.

  Here, in the MB gaming state, when replay (2) is won, a process for controlling the bell 7 (white 7 bell) to be drawn with priority using the draw priority table will be described. As described above, in the MB gaming state, the internal winning combination storage areas of the bells 1 to 7 and the watermelon are turned on in every game, and the internal lottery table is referenced to determine whether or not only the replay has been won internally. decide.

  Further, in the MB gaming state, a pull-in priority table with a pull-in priority table number “01” is used. Here, a case where the replay (2) is won and the 7C stop button is pressed at the timing when the cherry-white 7-watermelon (design positions 9 to 7) is displayed on the middle reel will be described as an example. In this case, since the combination corresponding to the symbol “white 7” is “replay 2, 3” and “bell 7”, the pull-in rank data “008H” and “006H” of both are added to obtain “014H”. To do. Further, there is a bell 1 (symbol position 5) within four sliding pieces, and the pull-in rank data of the bells 1 and 2 corresponding to the symbol “bell 1” is “009H”. Here, the pull-in rank data “014H” and “009H” are compared, and since “014H” has a higher value, the symbol “white 7” is given priority over the symbol “bell 1”. Control. The remaining reels are controlled to be displayable when a stop operation is performed within a range where white 7 can be displayed by a display combination storing area and a symbol code storing process which will be described later.

[Configuration of storage area provided in main RAM]
Next, the configuration of various storage areas provided in the main RAM 33 will be described with reference to FIGS. Various storage areas may be provided not only in the main RAM 33 but also in the sub RAM of the sub control circuit 72.

[Internal winning combination storage area]
FIG. 12 shows an internal winning combination storing area 1 and an internal winning combination storing area 2 in which data indicating the internal winning combination (winning request flag) is stored. The internal winning combination determined in the internal lottery process is stored in the corresponding area.

[Coverage storage area]
FIG. 13 shows a carryover combination storage area in which data relating to a carryover combination is stored. For example, when BB is determined as the internal winning combination in the internal lottery process, “1” is stored in bit 0 of the carryover combination storing area. Here, when the carryover combination is permitted over one or a plurality of games that a combination of symbols corresponding to the data pointer determined in the internal lottery process described later is allowed to be displayed along the winning line, the data pointer Is provided for the main CPU 31 to identify.

[Game state flag storage area]
FIG. 14 shows a game state flag storage area in which data indicating the game state flag is stored. The value of the gaming state flag is used by the main CPU 31 to identify the current gaming state. For example, “1” is stored in bit 0 in the RT0 gaming state. Here, the internal lottery table shown in FIG. 7 described above is set by the main CPU 31 in accordance with the data indicating the game state flag stored in the game state flag storage area. For example, when “1” is stored in bit 0, the internal lottery table for RT0 is set by the main CPU 31.

[Multiple storage area when MB is operating]
FIG. 15 shows a storage area for storing the number of medals during MB operation in which the number of medals to be stored is stored. For example, when the MB symbol is displayed on the active line and the MB is activated, if the number of medals inserted by the player is “3”, the bit 1 is updated to “1”, and the player If the number of inserted medals is “2”, bit 0 is updated to “1”. The data stored in the multiplied number storage area during MB operation is data read to the main CPU 31 when setting the internal lottery table during the MB game.

[Push order storage area]
FIG. 16 shows a pressing order storage area in which data indicating the order of stop operations is stored. For example, when the left stop button 7L is operated in the first stop operation, “1” is stored in bits 0 and 1. After that, when the middle stop button 7C is operated as the second stop operation, among the bits 0 and 1 storing “1”, bit 1 is updated to “0”, and bit 0 is set to “1”. Keep it.

[Operation stop button storage area]
FIG. 17 shows an operation stop button storage area in which data indicating stop buttons 7L, 7C, and 7R that have been pressed this time, so-called operation stop buttons, are stored. In the operation stop button storage area, data indicating stop buttons 7L, 7C, and 7R that are effective to be pressed, that is, so-called effective stop buttons are also stored. In the present embodiment, the main CPU 31 identifies the currently pressed stop buttons 7L, 7C, 7R based on the data stored in bits 0-2 of the operation stop button storage area. Further, the main CPU 31 identifies stop buttons 7L, 7C, and 7R that have not been pressed, based on data stored in bits 4 to 6 of the operation stop button storage area.

[Retrieve priority data storage area]
FIG. 18 shows a pull-in priority data storage area in which preferential pull-in rank data is stored corresponding to each symbol position data. The pull-in priority data storage area includes a pull-in priority data storage area for the left reel, a pull-in priority data storage area for the middle reel, and a pull-in priority data storage area for the right reel. Each drawing priority order data storage area stores priority drawing order data for each of the symbol position data of the reels 3L, 3C, 3R corresponding to the drawing priority order data storage area. The priority pull-in order data is displayed when the symbol located in one symbol position data is displayed at the center line position, or the combination of symbols related to any display combination or a part thereof is displayed along any of the winning lines. It is data indicating whether or not

[Program flow executed in pachislot]
Next, contents of a program executed by the main CPU 31 of the main control circuit 71 will be described with reference to FIGS.

[Main flowchart by control of main CPU of main control circuit]
With reference to FIG. 19, the main flowchart which showed the main processes which the main CPU31 performs is demonstrated.

  First, the main CPU 31 performs an initialization process (step S1), and proceeds to step S2. In this process, the main CPU 31 determines whether or not the backup is normal and whether or not the setting has been appropriately changed, and performs an initialization process according to the determination result.

  Subsequently, the main CPU 31 performs an initialization process at the end of one game (step S2). For example, the main CPU 31 clears data stored in an internal winning combination storage area, a display combination storage area, or the like. Then, the main CPU 31 performs a medal acceptance / start check process which will be described later with reference to FIG. 20 (step S3).

  Next, the main CPU 31 extracts the random number for lottery and stores it in the random value storage area (step S4). The random number for lottery extracted in the process of step S4 is used in the internal lottery process (FIG. 21 described later). Subsequently, the main CPU 31 performs an internal lottery process which will be described later with reference to FIG. 21 (step S5). In this process, the main CPU 31 determines an internal winning combination.

  Next, based on the result of the internal lottery process, the main CPU 31 performs a reel stop initial setting process (described later in detail with reference to FIG. 22) for storing information related to reel stop control (step S6). In this process, the main CPU 31 initializes an area related to control for stopping the rotation of the reels 3L, 3C, and 3R.

  Next, the main CPU 31 performs a start command transmission process (step S7). In this process, the main CPU 31 stores the start command in the communication data storage area of the main RAM 33. The start command includes information such as a game state and an internal winning combination, and is transmitted to the sub control board 72 in a command data transmission process of an interrupt process described later. Thereby, the sub control board 72 can produce an effect according to the start operation.

  Subsequently, the main CPU 31 performs a wait process (step S8). In this process, the main CPU 31 stands by until a predetermined time (for example, 4.1 seconds) elapses from the start of the previous game. Subsequently, the main CPU 31 performs a reel rotation start process (step S9). In this process, the main CPU 31 requests the start of rotation of the reels 3L, 3C, 3R and stores a reel rotation start command in the communication data storage area of the main RAM 33.

  Then, the main CPU 31 performs a drawing priority order storage process (detailed later using FIG. 23) (step S10). In this process, on the basis of the result of the internal lottery process, for each symbol position of the rotating reel, when the stop is permitted, the drawing priority data is stored, and when the stop is not permitted (that is, In the case where a winning combination is won, the suspension prohibition is stored.

  Next, the main CPU 31 performs a reel stop control process which will be described later with reference to FIG. 26 (step S11). Subsequently, the main CPU 31 performs a winning search process (step S12). In this process, the main CPU 31 compares the symbol combination displayed along the active line with the symbol combination table after the reels 3L, 3C, and 3R are stopped, determines the display combination, and determines the number of medals to be paid out. Do.

  Next, the main CPU 31 pays out medals based on the payout number of medals determined in step S12 (step S13). Subsequently, the main CPU 31 stores the display command in the communication data storage area of the main RAM 33. The stored display command is transmitted to the sub-control board 72 in a command data transmission process of an interrupt process described later (step S14).

  Subsequently, the main CPU 31 performs RT control processing which will be described later with reference to FIG. 29 (step S15). In this process, the RT gaming state flag is updated according to the display combination.

  Subsequently, the main CPU 31 performs a bonus end check process which will be described later with reference to FIG. 30 (step S16). In this process, the main CPU 31 ends the operation of the bonus game when a condition for ending the bonus game is satisfied. Subsequently, the main CPU 31 performs a bonus operation check process which will be described later with reference to FIG. 31 (step S17), and then performs a process of step S2. In this process, the main CPU 31 starts operation of the bonus game when the conditions for starting the bonus game are satisfied, and operates the regame when the conditions for replay are satisfied.

[Medal reception / start check processing]
With reference to FIG. 20, the medal acceptance / start check process will be described which shows the procedure of the process in which the main CPU 31 determines whether or not the start operation is possible based on the number of inserted sheets.

  First, the main CPU 31 determines whether or not there is a value of the automatic insertion counter, that is, whether or not it is “0” (step S31). Here, the value of the automatic insertion counter being “0” indicates that the replay is non-winning in the previous game. At this time, if there is a value of the automatic insertion counter, that is, if it is other than “0”, the main CPU 31 subsequently performs an automatic insertion process (step S32), and proceeds to step S39.

  Specifically, the main CPU 31 copies the value of the automatic insertion counter to the insertion number counter. The automatic insertion counter is a counter provided for the main CPU 31 to count the number of medals to be automatically inserted, and the insertion number counter is provided for the main CPU 31 to count the number of medals inserted. Counter. The automatic insertion counter and the insertion number counter are stored in predetermined areas of the main RAM 33.

  On the other hand, if the value of the automatic insertion number counter is not present, that is, “0”, the main CPU 31 permits medal reception (step S33), and then performs the process of step S34.

  In step S34, the main CPU 31 sets a maximum value of the number of inserted coins according to the gaming state. In this embodiment, the main CPU 31 sets “3” as the maximum value of the inserted number in all gaming states.

  Subsequently, the main CPU 31 determines whether or not medal acceptance is permitted (step S35). When this determination is YES, the main CPU 31 continues to perform the process of step S36, and when NO, the main CPU 31 continues to perform the process of step S39.

  In step S36, the main CPU 31 performs medal insertion check processing. In this process, the main CPU 31 checks the input from the medal sensor 42S. Subsequently, the main CPU 31 performs medal insertion command transmission processing (step S37). In this process, the main CPU 31 stores a medal insertion command in the communication data storage area of the main RAM 33. The stored medal insertion command is transmitted to the sub control board 72 in a command data transmission process of an interrupt process described later.

  Subsequently, the main CPU 31 determines whether or not the inserted number is a game start possible number (step S38). For example, the main CPU 31 determines whether or not the value of the insertion number counter is “2” or “3”. In the present embodiment, two or three are set as the number of games that can be started. This means that the number of medals inserted can be two or three and the game can be started. At this time, if the value of the inserted number counter is “2” or “3”, the main CPU 31 subsequently performs the process of step S39, and the value of the inserted number counter is not “2” or “3”. In that case, the main CPU 31 subsequently performs the process of step S35.

  In step S39, the main CPU 31 determines whether or not the start switch 6S is on. Specifically, the main CPU 31 determines whether or not there is an input from the start switch 6S based on the operation of the start lever 6. At this time, if there is an input from the start switch 6S, the main CPU 31 prohibits medal acceptance (step S40) and ends the medal acceptance / start check processing. On the other hand, when there is no input from the start switch 6S, the main CPU 31 subsequently performs the process of step S35.

[Internal lottery processing]
With reference to FIG. 21, an internal lottery process showing a procedure of a process in which the main CPU 31 determines an internal winning combination based on a random number value, a gaming state, and the like will be described.

  First, the main CPU 31 determines whether an MB game is being played (step S41). Specifically, the main CPU 31 determines whether or not the MB gaming state flag is on. As a result, when the MB gaming state flag is ON, an internal lottery table corresponding to the number-of-times storing area for MB operation is set (step S42), and the process proceeds to step S44.

  If the MB gaming state flag is not on, the main CPU 31 sets an internal lottery table corresponding to the gaming state and the number of pieces to be multiplied (step S43), and proceeds to step S44. Subsequently, the main CPU 31 acquires a random number value stored in the random value storage area (step S44).

  Next, the main CPU 31 refers to the internal lottery table, acquires a lottery value corresponding to the winning number, and subtracts the lottery value from the random number value (step S45). Subsequently, the main CPU 31 determines whether or not the subtraction result is less than “0” (negative) (step S46). At this time, if the subtraction result is negative, the main CPU 31 obtains the small role / replay data pointer and bonus data pointer corresponding to the winning number (step S50), and then performs the processing of step S51. Do. On the other hand, if the subtraction result is not negative, the main CPU 31 subsequently performs the process of step S47.

  In step S47, the main CPU 31 updates the random number and updates the winning number. Specifically, the main CPU 31 updates the random number value to the value after subtraction in step S45 and updates it to the winning number that has not been checked yet. Subsequently, the main CPU 31 determines whether or not all winning numbers have been checked (step S48). At this time, if all winning numbers are checked, the main CPU 31 sets “0” in the data pointer (step S49), and proceeds to step S51. On the other hand, if not all the winning numbers are checked, the main CPU 31 proceeds to step S45.

  In step S51, the main CPU 31 refers to the small winning combination / replay internal winning combination determination table and acquires the internal winning combination based on the small winning combination / replay data pointer. Subsequently, the main CPU 31 stores it in the internal winning combination storing area corresponding to the acquired internal winning combination (step S52).

  Subsequently, the main CPU 31 determines whether the carryover combination storage area is “0” (step S53). As a result, when the carryover combination storage area is “0”, the internal winning combination determination table for bonus is referred to, and the internal winning combination is acquired based on the bonus data pointer (step S54).

  Subsequently, the main CPU 31 stores the internal winning combination storing area corresponding to the acquired internal winning combination (step S55), and proceeds to step S56. On the other hand, if the carryover combination storage area is not “0”, the main CPU 31 proceeds to step S56. In step S56, the internal symbol combination storing area is updated based on the internal symbol combination stored in the carryover combination storing area (step S56), and the internal lottery process is terminated.

[Reel stop initial setting process]
With reference to FIG. 22, the reel stop initial setting process in which the main CPU 31 shows the procedure of the process of storing each piece of information related to the reel stop control based on the result of the internal lottery process will be described.

  First, the main CPU 31 refers to the turning cylinder stop number selection table, and obtains the turning cylinder stop number based on the internal winning combination (step S57). The spinning cylinder stop number selection table is a table in which various information used for stop control is defined in association with the spinning cylinder stop number corresponding to the data pointer. Subsequently, the main CPU 31 refers to the reel stop initial setting table, and acquires each piece of information based on the rotation stop number (step S58). For example, the main CPU 31 acquires the pull-in priority table number and the like.

  Then, the main CPU 31 stores the rotating identifier in the symbol code storage area (step S59). That is, the main CPU 31 turns on the bits of all symbol code storage areas (excluding unused areas). Thereafter, the main CPU 31 stores 3 in the stop button non-operation counter (step S60), and ends the reel stop initial setting process. The stop button non-operating counter is used to determine the number of stop buttons 7L, 7C, 7R that are not stopped by the player, and is stored in a predetermined area of the main RAM 33.

[Retrieve priority storage processing]
Referring to FIG. 23, in accordance with the result of the internal lottery process, for each symbol position of the rotating reel, when the stop is permitted, the drawing priority data is stored, and when the stop is not permitted. (In other words, in the case where a winning combination is won, etc.), a drawing priority order storing process showing a procedure for storing stop prohibition will be described.

  First, the main CPU 31 stores the value of the stop button non-operating counter as the number of searches (step S61). Subsequently, the main CPU 31 performs a search target reel determination process (step S62). In this process, the reels to be searched are determined in order from the reel on the left side of the rotating reels 3L, 3C, and 3R.

  Next, the main CPU 31 performs a pull-in priority table selection process which will be described later with reference to FIG. 24 (step S63). Subsequently, the main CPU 31 sets “21” as the number of symbol checks and “0” as the search symbol position (step S64). Next, the main CPU 31 performs a symbol code storing process which will be described later with reference to FIG. 25 (step S65).

  Next, the main CPU 31 updates the display combination storing area based on the symbol code acquired in step S65 and the symbol code storing area (step S66). Subsequently, the main CPU 31 performs a pull-in priority data acquisition process (step S67). In this process, the main CPU 31 plays the role corresponding to the bit storing “1” in the display combination storing area, and corresponding to the bit storing “1” in the internal winning combination storing area. Referring to the pull-in priority table selected in step S63, pull-in priority data is acquired.

  Next, the main CPU 31 stores the acquired drawing priority data in the drawing priority data storage area corresponding to the search target reel (step S68). Subsequently, the main CPU 31 subtracts “1” from the number of symbol checks and adds “1” to the search symbol position (step S69).

  Next, the main CPU 31 determines whether or not the number of symbol checks is “0” (step S70). When the determination is YES, the main CPU 31 performs the process of step S71, and when the determination is NO, the main CPU 31 performs the process of step S65. In this process, it is determined whether all searches for symbol positions “0” to “20” have been performed. In step S71, the main CPU 31 determines whether or not the search has been performed for the number of times of search. When this determination is YES, the main CPU 31 ends the pull-in priority order storage process, and when NO, performs the process of step 62. In this process, it is determined whether or not a search has been performed for all reels.

[Pull-in priority table selection processing]
With reference to FIG. 24, a description will be given of a pull-in priority table selection process for selecting a pull-in priority table for selecting a pull-in priority.

  First, the main CPU 31 determines whether or not a pull-in priority table number is set (step S72). When this determination is YES, the main CPU 31 subsequently performs the process of step 73, and when NO, the main CPU 31 ends the pull-in priority table selection process.

  In step S73, the main CPU 31 refers to the pressing order storage area and the operation stop button storage area, sets the corresponding drawing priority table number (step S73), and ends the drawing priority table selection process.

[Design code storage processing]
With reference to FIG. 25, the symbol code storing process for acquiring the symbol code based on the set retrieved symbol position will be described.

  First, the main CPU 31 sets valid line data (step S74). In the present embodiment, since there are four effective lines, four lines (“upper stage-upper stage-upper stage, middle stage-middle stage-middle stage, upper stage-middle stage-lower stage, lower stage-middle stage-upper stage) are set. The main CPU 31 acquires the symbol code of the symbol position data for check (step S75), and ends the symbol code storage process.

[Reel stop control process]
With reference to FIG. 26, the reel stop control process in which the main CPU 31 stops the rotation of the reels 3L, 3C, 3R based on the internal winning combination or the timing of the stop operation by the player will be described.

  First, the main CPU 31 determines whether or not an effective stop button 7L, 7C, 7R has been pressed (step S81). At this time, if valid stop buttons 7L, 7C, and 7R are pressed, the main CPU 31 subsequently performs the process of step S82. On the other hand, when the effective stop buttons 7L, 7C, and 7R are not pressed, the main CPU 31 performs the process of step S81 again.

  In step S82, the main CPU 31 updates the pressing order storage area and the operation stop button storage area. Subsequently, the main CPU 31 subtracts “1” from the value of the stop button non-operating counter (step S83). Subsequently, the main CPU 31 determines a search target reel from the operation stop button (step S84).

  Subsequently, in step S85, the main CPU 31 stores the stop start position based on the symbol counter. Next, the main CPU 31 performs a sliding piece number determination process which will be described later with reference to FIG. 27 (step S86). In this process, the main CPU 31 refers to the stop table to determine the number of sliding piece determination data determined for the stop start position.

  Subsequently, the main CPU 31 performs a reel stop command transmission process (step S87). In this process, the main CPU 31 stores a reel stop command in the communication data storage area of the main RAM 33. The reel stop command includes information on the operation stop button and the like, and is transmitted to the sub control board 72 in a command data transmission process of an interrupt process described later. Thereby, the sub control board 72 can produce an effect according to the stop operation.

  Subsequently, the main CPU 31 determines and stores a scheduled stop position of the search target reel based on the stop start position and the number of sliding pieces (step S88). Subsequently, the main CPU 31 sets the planned stop position as a search symbol position (step S89), and performs the symbol code storage process described in FIG. 25 (step S90). Then, the main CPU 31 updates the symbol code storage area from the symbol code acquired in step S90 (step S91).

  Subsequently, the main CPU 31 performs a control change process for updating the reel stop control information group when the stop position is a specific stop position (step S92). Next, the main CPU 31 determines whether or not the value of the stop button non-operating counter is “0” (step S93). At this time, if the value of the stop button non-operation counter is not “0” (not at the time of the third stop), the main CPU 31 performs the pull-in priority storage process described with reference to FIG. 23 (step S94). Then, the process of step S81 is performed.

  That is, in the pachi-slot 1, before the process of stopping the rotation of the next reel 3L, 3C, 3R is performed, the process of storing the drawing priority data for each symbol position of the reels 3L, 3C, 3R still rotating Is done. On the other hand, when the value of the stop button non-operating counter is “0”, the main CPU 31 determines that the stop control at the time of the third stop has ended, and ends the reel stop control process. If the value of the button inactive counter is “0”, the reel stop control process is terminated as it is.

[Sliding piece number determination processing]
With reference to FIG. 27, the sliding piece number determination process will be described in which the main CPU 31 refers to the stop table and shows the procedure of the process of determining the sliding piece number determination data determined for the stop start position.

  First, the main CPU 31 determines whether or not the random line mask change valid bit is on (step S95). When this determination is YES, the process proceeds to step S97, and when it is NO, the main CPU 31 performs the process of step S96.

  In step S96, the main CPU 31 performs a process of setting line mask data corresponding to the operation stop button. Then, the main CPU 31 determines whether or not it is the first stop time (the value of the stop button non-operation counter is 2) (step S97). At this time, if it is the time of the first stop, the main CPU 31 subsequently performs the process of step S99. If it is not the time of the first stop, the main CPU 31 subsequently performs the process of step S98.

  In step S98, the main CPU 31 performs second and third stop processing, and performs processing in step S100. In step S99, the main CPU 31 performs a first stop process and performs the process of step S100. In step 100, a priority pull-in control process described later with reference to FIG. 28 is performed (step S100).

[Priority pull-in control processing]
With reference to FIG. 28, the priority attraction-in control process showing the procedure of the process in which the main CPU 31 determines the number of sliding symbols will be described.

  First, the main CPU 31 sets a pull-in priority data storage area corresponding to the operation stop button (step S101). Subsequently, the main CPU 31 acquires a stop start position (step S102).

  Next, the main CPU 31 determines whether an MB game is being played (step S103). As a result, when it is determined that the MB game is being played, the main CPU 31 performs the process of step S106, and when it is determined that the MB game is not being played, the main CPU 31 performs the process of S104.

  In step S104, the main CPU 31 sets a priority order table corresponding to the number of sliding piece determination data. Then, the main CPU 31 sets 5 as the initial value of the priority order and the number of checks (step S105), and performs the process of step S108.

  In step S106, the main CPU 31 sets an MB gaming state priority order table corresponding to the number of sliding piece determination data. Then, the main CPU 31 sets “5” as the initial value of the priority order and sets “2” as the number of checks (step S107).

  Next, the main CPU 31 sets the sliding piece number determination data as the number of sliding pieces (step S108). Subsequently, the main CPU 31 extracts a stop search position based on the stop start position and the priority order (step S109). Next, the main CPU 31 acquires pull-in priority order data of the stop search position (step S110).

  Subsequently, the main CPU 31 determines whether or not it is equal to or more than the previously acquired pull-in priority data (step S111). At this time, if it is equal to or higher than the previously acquired priority pull-in order data, the main CPU 31 updates the number of sliding frames (step S112), and then performs the process of step S113. On the other hand, if it is less than the previously acquired priority pull-in order data, the main CPU 31 subsequently performs the process of step S113.

  In step S113, the main CPU 31 subtracts “1” from the priority order and the number of checks. Subsequently, the main CPU 31 determines whether or not the number of checks is “0” (step S114). At this time, if the number of checks is “0”, the main CPU 31 sets the updated number of sliding frames (step S115) and ends the priority pull-in control process. On the other hand, if the number of checks is not “0”, the main CPU 31 subsequently performs the process of step S109.

[RT control processing]
The RT control process will be described with reference to FIG. As shown in FIG. 29, the main CPU 31 determines whether or not BB1 or BB2 is winning internally (step S121). As a result, when BB1 or BB2 is internally winning, the main CPU 31 updates the gaming state to the BB internal winning combination (step S122), and ends the RT control process. Further, when the BB1 or BB2 is not internally won, the main CPU 31 determines whether or not the MB is not won and the display combination is a watermelon (RT2 transition symbol) (step S123).

  As a result, when the MB is not winning and the display combination is watermelon, the main CPU 31 updates the gaming state to the RT2 gaming state (step S124), and ends the RT control process. On the other hand, if the MB is not MB winning or the display combination is not a watermelon, the main CPU 31 determines whether or not the BB1 end flag is on (step S125). As a result, when the BB1 end flag is on, the main CPU 31 updates the gaming state to RT2 (step S126), and ends the RT control process. On the other hand, when the BB1 end flag is not on, the main CPU 31 determines whether or not the BB2 end flag is on (step S127).

  As a result, when the BB2 end time flag is on, the main CPU 31 updates the gaming state to RT2 (step S126), and ends the RT control process. On the other hand, if the BB2 end flag is not on, the main CPU 31 determines whether or not a bell spill is displayed (step S129). As a result, when the bell spill is displayed, the main CPU 31 updates the gaming state to RT1 (step S130) and ends the RT control process. On the other hand, when the bell spill is not displayed, the main CPU 31 ends the RT control process as it is.

[Bonus end check process]
With reference to FIG. 30, the priority attraction control process showing the procedure of the process of ending the operation of the bonus game when the main CPU 31 satisfies the condition for ending the bonus game will be described.

  First, if the BB or MB end flag is on, the main CPU 31 updates it to off (step S141), and determines whether the BB1 or BB2 is operating, that is, whether the BB in-game state flag is on. (Step S142). As a result, when the BB1 or BB2 is operating, the main CPU 31 performs the process of step S143. When the BB1 or BB2 is not operating, the main CPU 31 performs the process of step S146.

  In step S143, the main CPU 31 determines whether or not the value of the bonus end number counter is smaller than “0”. As a result, when the value of the bonus end number counter is not smaller than “0”, the main CPU 31 ends the bonus end check process. When the value of the bonus end number counter is smaller than “0”, the main CPU 31 performs a BB end process for turning off the BB gaming state flag during BB (step S144), and turns on the BB1 or BB2 end flag. In step S145, the process of step S150 is performed.

  In step S146, the main CPU 31 determines whether the MB is operating, that is, whether the MB gaming state flag is on. As a result, when the MB is not operating, the main CPU 31 ends the bonus end check process. Further, when the MB is operating, the main CPU 31 determines whether or not the value of the bonus end number counter is smaller than “0” (step S147). As a result, when the value of the bonus end number counter is not smaller than “0”, the main CPU 31 ends the bonus end check process.

  Further, if the value of the bonus end number counter is smaller than “0”, the main CPU 31 performs MB end processing for turning off the MB gaming state flag (step S148), and turns on the MB end time flag (step S148). S149).

  Then, the main CPU 31 performs a bonus end command transmission process for transmitting bonus end command data to the sub-control board 72 (step S150), performs a bonus end initialization process (step S151), and performs a bonus end check. The process ends.

[Bonus activation check process]
The bonus operation check process will be described with reference to FIG. First, the main CPU 31 determines whether or not an MB symbol is displayed, that is, whether or not an MB is won (step S161). As a result, when the MB symbol is displayed, it is determined whether or not the number of sheets to be multiplied is 3 (step S162). Bit 1 is turned on (step S163). On the other hand, if the number of sheets to be multiplied is not three, that is, if the number of sheets to be multiplied is two, bit 0 of the number-of-times-of-multiple storage area is turned on during MB operation (step S164). That is, the main CPU 31 stores the multiplier at the time of MB operation in the storage area for the number of times of MB operation.

  Then, the main CPU 31 performs MB operation processing (step S165). In the MB operation process, the MB gaming state flag is turned on and 120 is set in the bonus end number counter.

  Then, the main CPU 31 clears the value of the carryover combination storage area (step S166), performs a bonus start command transmission process (step S167), and ends the bonus operation check process. If the MB symbol is not displayed in step S161, the main CPU 31 determines whether the BB1 or BB2 symbol is displayed (step S168). As a result, when the BB1 or BB2 symbol is displayed, the main CPU 31 performs the process of step S169, and when the BB is not operating, performs the process of step S172.

  In step S169, the main CPU 31 performs an BB RB operation process of turning on the RB gaming state flag during BB and setting 300 in the bonus end number counter (step S169). Then, the main CPU 31 clears the value of the carryover combination storage area (step S170), performs a bonus start command transmission process for transmitting a bonus start command to the sub control board 72 (step S171), and ends the bonus operation check process. To do.

  If the BB1 or BB2 symbol is not displayed, it is determined whether or not the replay has been won (step S172). As a result, when the replay is won, the main CPU 31 makes an automatic insertion request for copying the value of the insertion number counter to the automatic insertion number counter (step S173), and ends the bonus operation check process. On the other hand, if the replay is not won, the main CPU 31 ends the bonus operation check process as it is.

[Interrupt processing under the control of the main CPU (1.1172 msec)]
With reference to FIG. 32, an interrupt process by the control of the main CPU 31 showing a procedure of an interrupt process executed by the main CPU 31 every predetermined time (for example, 1.1172 ms) will be described.

  First, the main CPU 31 saves the register (step S201). Subsequently, the main CPU 31 performs input port check processing (step S202). In this process, the main CPU 31 confirms the presence / absence of a signal transmitted to the microcomputer 30. For example, the main CPU 31 stores the on-edge and off-edge of the start switch 14S, the stop switch 7S, etc. for each interrupt process. Further, the main CPU 31 stores an input state command including information on the on-edge and off-edge of various switches in the communication data storage area of the main RAM 33. The stored input state command is transmitted to the sub control board 72 in a communication data transmission process of an interrupt process described later. Accordingly, various effects can be executed using the operation means such as the start lever 6 and the stop buttons 7L, 7C, and 7R.

  Subsequently, the main CPU 31 performs a timer update process (step S203). Next, the main CPU 31 performs command data transmission processing (step S204). In this process, the command stored in the communication data storage area is transmitted to the sub control board 72. Subsequently, the main CPU 31 performs a reel control process (step S205). For example, the main CPU 31 controls the rotation of the reels 3L, 3C, 3R. More specifically, the main CPU 31 starts the rotation of the reels 3L, 3C, and 3R in response to a request for starting the rotation of the reels 3L, 3C, and 3R, that is, in response to the start operation. Control is performed so that 3L, 3C, and 3R rotate. Further, in accordance with the stop operation, control is performed so that the rotation of the reels 3L, 3C, 3R corresponding to the stop operation stops.

  Subsequently, the main CPU 31 performs a lamp / 7SEG drive process (step S206). For example, the main CPU 31 displays the number of credited medals, the number of payouts, etc. on various display units. Subsequently, the main CPU 31 restores the register (step S207), and terminates the interrupt processing that occurs periodically.

[Program flow executed by sub CPU of sub control board]
Next, the contents of the program executed by the sub control circuit 72 will be described with reference to FIGS.

  First, the sub CPU performs initialization processing (step S301), and proceeds to step S302. In this process, the sub CPU performs error check of the sub RAM 83 and the like, and initializes the task system. The task system includes a lamp control task, a sound control task, which are timer interrupt synchronization task groups, and a mother task, which is a VSYNC (Vertical Synchronization) interrupt synchronization task group.

  In step S302, the production control task is activated, and the process proceeds to step S303. The production control task will be described later with reference to FIG. 34, but it waits for the sub CPU to receive a timer interrupt event message transmitted every 2 ms to the sub CPU. In response to the reception by the CPU, the sub CPU performs a process for controlling the lighting state of various lamps and a process for controlling the sound output state from the speakers 9L and 9R.

  In step S303, the main board communication task is activated and the process is terminated. The main board communication task will be described later with reference to FIG. 35. This is a task group for VSYNC (vertical synchronization signal) interrupt synchronization, and a liquid crystal display is displayed when one frame of video is displayed on the liquid crystal display device 5. A vertical synchronization signal (VSYNC interrupt signal) sent from the device 5 is used.

[Direction control task]
With reference to FIG. 34, the production control task will be described. First, the sub CPU determines whether the control data has been updated (step S311). As a result, when the control data is updated, the sub CPU performs a control data output process (step S312), and proceeds to step S311. When the control data is not updated, the sub CPU directly performs step S311. Return to.

[Main board communication task]
The main board communication task performed by the sub CPU will be described with reference to FIG. First, the sub CPU initializes the communication messenger queue (step S321), and proceeds to step S322. In step S322, command reception is checked, and the process proceeds to step S323. In step S323, it is determined whether a command different from the previous command is received. When this determination is YES, the process proceeds to step S324, and when this determination is NO, the process proceeds to step S322.

  In step S324, game information such as an internal winning combination, gaming state, setting value, RT game number counter value and the like is created and stored from the received command parameters, and the process proceeds to step S325. In step S325, command analysis processing described later with reference to FIG. 36 is performed, and the flow proceeds to step S322.

[Command analysis processing]
A command analysis process performed by the sub CPU will be described with reference to FIG. First, the sub CPU determines whether or not it is time to receive an initialization command (step S331). If it is during initialization command reception, the sub CPU performs initialization command reception processing (step S332) and ends the command analysis processing. In this process, for example, setting value information is acquired. In addition, the type of stage for staying in the initial state is determined.

  On the other hand, if the initialization command is not received, the sub CPU subsequently determines whether or not it is a medal insertion command reception (step S333). When the medal insertion command is received, the sub CPU performs a medal insertion command reception process (step S334), and ends the command analysis process. In this process, for example, information on the presence / absence of medals and the values of the inserted number counter and the credit counter are acquired.

  On the other hand, if it is not at the time of receiving the medal insertion command, the sub CPU subsequently determines whether or not it is at the time of receiving the start command (step S335). When the start command is received, the sub CPU performs a start command reception process described later with reference to FIG. 44 (step S336), and ends the command analysis process.

  On the other hand, if it is not at the time of receiving the start command, the sub CPU subsequently determines whether or not it is at the time of receiving the reel rotation start command (step S337). If it is time to receive a reel rotation start command, the sub CPU performs a reel rotation start command reception process (step S338), and ends the command analysis process. In this process, for example, an effect accompanying the rotation of the reels 3L, 3C, 3R is performed.

  On the other hand, when the reel rotation start command is not received, the sub CPU subsequently determines whether or not it is a reel stop command reception (step S339). If it is time to receive a reel stop command, the sub CPU performs a process when a reel stop command is received (step S340), and ends the command analysis process. In this process, for example, an effect corresponding to the stop operation is performed.

  On the other hand, if it is not at the time of receiving the reel stop command, the sub CPU subsequently determines whether or not it is at the time of receiving the display command (step S341). If the display command is received, the sub CPU performs a display command reception process (step S342), and ends the command analysis process. In this process, for example, information on the display combination and the number of payouts is acquired.

  On the other hand, if the display command is not received, the sub CPU subsequently determines whether or not it is a bonus start command reception (step S343). When the bonus start command is received, the sub CPU performs a bonus start command reception process (step S344), and ends the command analysis process. In this process, for example, an effect for starting the bonus is performed.

  On the other hand, if it is not at the time of receiving the bonus start command, the sub CPU subsequently determines whether or not it is at the time of receiving the bonus end command (step S345). If it is time to receive a bonus end command, the sub CPU performs a bonus end command reception process (step S346) and ends the command analysis process. In this process, for example, an effect at the end of the bonus is performed.

  On the other hand, if it is not at the time of receiving the bonus end command, the sub CPU subsequently determines whether or not it is at the time of receiving the input state command (step S347). If the input state command is being received, the sub CPU performs an input state command reception process (step S348) and ends the command analysis process. In this process, for example, the types of the start lever 6 and stop buttons 7L, 7C, and 7R operated by the player are acquired. On the other hand, when the input state command is not received, the sub CPU ends the command analysis process.

[Start command reception processing]
With reference to FIG. 37, the process at the time of start command reception performed by the sub CPU will be described. First, the sub CPU determines whether or not the gaming state is the MB gaming state (step S351). When the gaming state is the MB gaming state, the sub CPU proceeds to the process of step S352, and when the gaming state is not MB, the sub CPU proceeds to the process of step S355.

  In step S352, the sub CPU determines whether the winning combination is replay (2). As a result, when the winning combination is replay (2), the sub CPU performs a notification effect process (step S353), turns on the AT flag (step S354), and ends the start command reception process. In the notification effect process, when the replay (2) is won in the MB, white bell winning is permitted, and therefore the sub CPU generates an effect such as “Aim at White 7!”. On the other hand, if the winning combination is not replay (2), the sub CPU proceeds to the process of step S355.

  In step S355, the sub CPU determines whether or not the winning combination is an AT lottery combination. As a result, when the winning combination is not the AT lottery combination, the process proceeds to step S358. If the winning combination is an AT lottery combination, the sub CPU determines whether or not the winning combination has been won (step S356). As a result, if it is determined that the AT is not won, the sub CPU proceeds to the process of step S358. If it is determined that the AT is won, the sub CPU turns on the AT flag (step S357) and ends the start command reception process. If the AT further wins during ART, the AT may be added.

  In step S358, the sub CPU determines whether or not the remaining number of ATs is 0 or more. As a result, if the remaining AT count is not equal to or greater than 0, the sub CPU ends the start command reception process. If the remaining AT count is 0 or more, the sub CPU determines whether or not the winning combination is a push order bell (step S359). As a result, if the winning combination is not the pressing order bell, the sub CPU ends the process at the time of receiving the start command. When the winning combination is a push order bell, the sub CPU performs a push order navigation effect process for notifying the correct push order (step S360), and ends the start command reception process.

[Effect of Example 1]
As described above, in the first embodiment, the pachislot 1 has an internal number corresponding to the number of game media inserted when the MB symbol (red 7-red 7-BAR) corresponding to the MB combination is stopped and displayed. With reference to the lottery table, replay lottery is performed during the MB game. Therefore, by changing the number of medals inserted when the player arranges the MB symbols, it is possible to create a state that is advantageous to the player, and it is possible to improve the gameability of the bonus game.

  Also, according to the first embodiment, there is only one type of MB symbol, but since the winning probability of replay can be changed according to the number of inserted symbols when displaying the MB symbol on the active line, As a result of diversifying the game characteristics during the MB game without preparing a plurality of types, it is possible to improve the game characteristics of the bonus game.

  By the way, in the first embodiment, the case where the RT1 gaming state and the RT2 gaming state are set as the RT gaming state has been described, but the present invention is not limited to this, and the RT gaming state is the RT1. A gaming state, an RT2 gaming state, and an RT3 gaming state may be set.

  Therefore, in the following second embodiment, the case where there are three types of RT gaming states will be described with reference to FIGS. 38 to 42. Note that the description of the same configuration and processing as in the first embodiment will be omitted. In the second embodiment, the probability that a replay (replay (1) or replay (2)) is determined as an internal winning combination is higher in the RT2 gaming state and the RT3 gaming state than in the RT1 gaming state. It is set high. That is, it can be said that the RT2 gaming state and the RT3 gaming state are more advantageous for the player than the RT1 gaming state.

  As shown in FIG. 38, in the pachi-slot 1, after the end of the BB gaming state, the state shifts to the RT2 gaming state. Thereafter, as in the first embodiment, in the RT2 gaming state, when the bell spilled eyes are displayed on the active line, the gaming state is shifted to RT1. Similarly to the first embodiment, in the RT1 gaming state, when the combination of symbols corresponding to the watermelon role (watermelon-watermelon-watermelon) is displayed on the active line and the MB is non-winning, The state is changed to RT3.

  In the second embodiment, in the RT1 gaming state or the RT2 gaming state, when the combination of symbols corresponding to the watermelon combination (watermelon-watermelon-watermelon) is displayed on the active line, and the MB is non-winning The game state is shifted to RT3. Further, in the RT3 gaming state, when the bell spilled eyes are displayed on the active line, the gaming state is shifted to RT1.

  Here, when a combination of symbols corresponding to a watermelon role is displayed on the active line, if a symbol corresponding to a watermelon is stopped and displayed when MB and watermelon are simultaneously won (MB + watermelon role), a game The state does not change. On the other hand, when the combination of symbols corresponding to the watermelon combination is displayed on the active line, if only the watermelon is won and the symbol corresponding to the watermelon is stopped and displayed, the gaming state shifts to RT3. Become. For this reason, it is possible to make it difficult for the player to understand whether or not the current RT gaming state has shifted from only the symbols displayed on the active line.

  Here, in the pachislot machine according to the second embodiment, as in the first embodiment, the internal lottery table used during the MB game (see FIG. 5) according to the number of medals inserted when the MB symbol is displayed on the active line. 39) is selected. Specifically, when the number of inserted pachislots is 2 (2) and the MB symbols are aligned on the active line, the gaming state (RT1 gaming state, RT2 gaming state or An internal lottery table corresponding to (RT3 gaming state) and an internal lottery table corresponding to the inserted number “2” is selected. Further, the pachislot 1 is an internal lottery table corresponding to the gaming state when the MB is won internally when the inserted number is 3 (3) and the MB symbols are aligned on the active line, and The internal lottery table corresponding to the inserted number “3” is selected.

  In the example of FIG. 39, the internal lottery table shows that the internal lottery table corresponding to the inserted number “3” has the inserted number “2” when the gaming state when the MB is won internally is the RT2 gaming state. The winning probability of replay (2) is set higher than that of the corresponding internal lottery table. On the other hand, in the example of FIG. 39, when the gaming state when the MB is won internally is the RT3 gaming state, the internal lottery table corresponding to the inserted number “2” is more than the inserted number “3”. The winning probability of replay (2) is set higher than the internal lottery table corresponding to “”.

  In other words, in the RT2 gaming state, setting the number of medals inserted at the time of aligning the MB symbols to 3 makes the winning probability of replay (2) during MB gaming higher, while RT3 In the gaming state, it is set so that the winning probability of the replay (2) in the MB game is higher when the number of inserted medals when matching the combination of symbols corresponding to the MB combination is two. Yes. For this reason, when the MB game is activated, the player guesses whether the gaming state is the RT2 gaming state or the RT3 gaming state, and aligns the MB symbol with two cards or aligns the MB symbol with three cards. As a result, it is possible to provide a game that maintains the interest of the player and improve the game performance of the bonus game. In addition, in the RT3 gaming state, when the MB symbols are arranged by multiplying two, the winning probability of the replay (2) during the MB game is the highest, and the possibility of adding the number of ART games is increased. It can be said that the gaming state is a more advantageous gaming state for the player compared to the RT2 gaming state.

[Internal lottery table determination table]
With reference to FIG. 40, the internal lottery table determination table used when the main CPU 31 determines the internal lottery table and the number of lotteries will be described.

  As in the first embodiment, the internal lottery table determination table defines information indicating the internal lottery table and information indicating the number of lotteries corresponding to the gaming state. As shown in FIG. 40, the internal lottery table determination table is different from the internal lottery table determination table shown in FIG. 10 in that an RT3 gaming state is added. The number of lotteries in the RT3 gaming state is “14”.

[Game state flag storage area]
FIG. 41 shows a game state flag storage area in which data indicating the game state flag is stored. The value of the gaming state flag is used by the main CPU 31 to identify the current gaming state. As shown in FIG. 41, the gaming state flag storage area is provided with a gaming state flag in bit 3 indicating that it is in the RT3 gaming state, as compared to the gaming state flag storage area shown in FIG. It will be different. In the RT3 gaming state, “1” is stored in bit 3.

[RT control processing]
The RT control process will be described with reference to FIG. Compared with the RT control process according to the first embodiment shown in FIG. 29, the RT control process according to the second embodiment shifts to the RT3 gaming state when the MB combination is non-winning and the watermelon is won. Is different.

  That is, as shown in FIG. 42, the main CPU 31 determines whether or not BB1 or BB2 is internally winning (step S181), and if BB1 or BB2 is not internally winning, the MB is not winning. And it is discriminate | determined whether a display combination is a watermelon (RT3 transfer symbol) (step S183). As a result, when the MB is not winning and the display combination is watermelon, the main CPU 31 updates the gaming state to the RT3 gaming state (step S184), and ends the RT control process.

  Further, as in the first embodiment, the main CPU 31 determines whether or not the BB1 end flag is on if the MB is not non-winning or the display combination is not a watermelon (step S185). As a result, when the BB1 end flag is on, the main CPU 31 updates the gaming state to RT2 (step S186), and ends the RT control process. On the other hand, when the BB1 end flag is not on, the main CPU 31 determines whether or not the BB2 end flag is on (step S187). As a result, when the BB2 end time flag is on, the main CPU 31 updates the gaming state to RT2 (step S186), and ends the RT control process. On the other hand, if the BB2 end time flag is not on, the main CPU 31 determines whether or not a bell spill is displayed (step S189). As a result, when the bell spill is displayed, the main CPU 31 updates the gaming state to RT1 (step S190) and ends the RT control process. On the other hand, when the bell spill is not displayed, the main CPU 31 ends the RT control process as it is.

  As described above, in the second embodiment, RT2 and RT3 are prepared in a state where replay is highly probable. In the case of RT2, the winning probability of replay (2) during MB games is higher when the number of medals inserted when aligning MB symbols is the first number (for example, 3). On the other hand, in the case of RT3, when the number of medals inserted when aligning the symbol combination corresponding to the MB combination is set to the second number (for example, 2), the replay (2 in the MB game) ) Is set to be high. For this reason, when the MB game is activated, the player guesses whether the gaming state is the RT2 gaming state or the RT3 gaming state, and aligns the MB symbol with two cards or aligns the MB symbol with three cards. As a result of the selection, it is possible to provide a game that maintains the interest of the player and improve the game performance of the bonus game.

  Further, according to the second embodiment, when the MB combination is non-winning and the watermelon wins, it is promoted to RT3, and when the bell combination of 5 selections is missed, it is demoted to RT1. . For this reason, when a combination of symbols corresponding to a watermelon is stopped and displayed, for example, when MB and a watermelon are won simultaneously and a watermelon is stopped and displayed, the gaming state does not change, while only a watermelon is displayed. If the watermelon is stopped and displayed, the gaming state will shift to RT3. As a result, it is possible to make it difficult for the player to understand the current RT gaming state, and to increase the enjoyment of inferring whether it is advantageous to arrange the MB symbols with two or three, and the player is more advantageous. It is possible to provide a game that maintains the interest of the game and improve the game performance of the bonus game.

  In the first embodiment, the case where the internal lottery table corresponding to the number of inserted sheets 2 and 3 is provided has been described. However, the present invention is not limited to this. A table may be provided, or an internal lottery table corresponding to the number of inserted sheets 1 and 3 may be provided.

  In the first embodiment, the pachislot machine 1 using three reels 3L, 3C, and 3R has been described as an example. However, the number of reels is not limited to three. For example, two or four or more reels may be used. Further, the number of choices such as a 5-choice bell may be changed as the number of reels increases or decreases. The number of choices may be changed not only by increasing / decreasing the number of reels but also by a combination of the number of reels and symbols.

  In the second embodiment, the case where the RT1 gaming state, the RT2 gaming state, and the RT3 gaming state are provided as the RT gaming state has been described. However, the present invention is not limited to this. For example, there may be three or more gaming states.

  In addition to the pachislot machine 1 as in the embodiment, the present invention can be applied to other gaming machines. Furthermore, the game can be executed by applying the present invention even in a game program in which the operation in the above-described pachislot machine 1 is executed in a pseudo manner for a home game machine. In that case, a CD-ROM, FD (flexible disk), or any other recording medium can be used as a recording medium for recording the game program.
