Description

  The present invention relates to a gaming machine such as a pachislot machine.

  Conventionally, it is detected that a plurality of reels having a plurality of symbols arranged on each surface, a game medal, a coin, etc. (hereinafter referred to as a “medal, etc.”) and a start lever is operated by a player, A start switch that requests the start of rotation of a plurality of reels and a stop button provided corresponding to each of the plurality of reels are detected by the player, and the stop of rotation of the corresponding reel is requested. A stop switch that outputs a signal, a stepping motor that is provided corresponding to each of the plurality of reels, and that transmits each driving force to each reel, and a stepping motor based on the signals output by the start switch and the stop switch The reel control unit controls the operation of each reel and rotates and stops each reel. When it is detected, lottery is performed based on the random number value, and the rotation of the reel is determined based on the result of the lottery (hereinafter referred to as “internal winning combination”) and the timing at which the stop button is detected. A so-called pachislot machine that stops is known.

  In recent years, as a gaming machine of this type, a replay related to replay is determined as an internal winning combination after the end of a big bonus (hereinafter simply referred to as BB) in which a game that gives a relatively large profit to a player can be performed a predetermined number of times. One that operates a gaming state with high probability (hereinafter simply referred to as “high RT”) is known (see, for example, Patent Document 1). Further, in this gaming machine, when the number of medals paid out during the operation of the BB is equal to or more than a predetermined number, in combination with the above-mentioned high RT, a specific internal winning combination (hereinafter simply referred to as a small role) Assist time (hereinafter simply referred to as AT) for notifying the user is activated. Such a state in which both high RT and AT are operated is referred to as ART.

  According to the gaming machine, during the operation of the ART, the probability that the winning combination is lost is lower than that in the general gaming state, and in contrast, the probability that the small combination is won is increased, so the number of medals to be paid out is increased. be able to. For this reason, an interest of a player can be attracted and the game nature can be improved.

  Also, in recent years, a predetermined number of special games (hereinafter referred to as chance zones) that are advantageous to the player are generated with a predetermined probability by internally winning a predetermined small role (for example, cherry) during general games. A gaming machine is known in which a predetermined number of chance zones are added with a predetermined probability by internally winning a predetermined small role in the chance zone (see, for example, Patent Document 2). According to the gaming machine, the interest of the player can be maintained by appropriately extending the number of continued games in the chance zone advantageous to the player.

  By the way, if the technical ideas described in Patent Documents 1 and 2 described above are combined, a gaming machine that generates an ART according to the gaming state at that time, or adds an ART, triggered by an internal winning of a predetermined small role It is also possible. Specifically, in this gaming machine, a predetermined number of ARTs are generated with a predetermined probability by internally winning a predetermined small role during a general game, and a predetermined small role is internally won during ART. Thus, a predetermined number of ARTs can be added to a continuing ART with a predetermined probability.

  However, in the gaming machine with the above combination, only a fixed number of ARTs are generated or added in response to the internal winning of a predetermined small role, and the profit that the player can obtain is monotonous. turn into. In particular, the profit given to the player by adding the ART does not vary depending on the gaming state when the ART is added. For this reason, there is a problem that the interest of the player is reduced with respect to the addition of ART.

  The present invention has been made in view of the above-described circumstances, and a gaming machine capable of improving the interest of a player as compared to the conventional game with respect to addition of a specific gaming state advantageous to the player such as a so-called ART. The purpose is to provide.

In order to achieve the above object, the gaming machine according to the present invention includes a plurality of reels displaying a plurality of symbols, a symbol display means for displaying a part of the symbols displayed on the reels, and a predetermined start condition. The symbol change means for changing the symbol by rotating the reel based on the establishment of the symbol, and the winning combination for determining the internal symbol combination from a plurality of combinations with a predetermined probability based on the establishment of the predetermined start condition Determining means; a stop operation detecting means provided corresponding to the plurality of reels for detecting a stop operation for stopping each reel; an internal winning combination determined by the winning combination determining means and the stop operation detection Stop control means for stopping the fluctuation of the symbol displayed on the symbol display means by stopping the rotation of the reel based on the timing when the stop operation is detected by the means; Display combination determination means for determining whether or not a combination is established based on a combination of symbols stopped on an effective line provided in the symbol display means based on the fact that the change of the symbols is stopped by the stop control means The first game mode and the first game mode are triggered by a predetermined transition condition between the first game mode and the second game mode that is more advantageous to the player than the first game mode. A game mode control means for switching between two game modes, and a specific game state operation for operating a specific game state that is advantageous for a player for a predetermined number of games when a specific start condition is established And the remaining game of the specific gaming state at the time of winning the predetermined role, on condition that the predetermined role is won during operation of the specific gaming state and the second gaming mode is established. The number of games in the specified game state when the specified game is won and the predetermined game is won during the operation of the specific game state and the first game mode is won. Special stock holding means that does not hold the number as a special stock, and when a predetermined grant condition is satisfied, the game mode is changed to the second game mode, and the number of the remaining games held in the special stock holding means And a specific game state providing means for providing a specific game state.
The gaming machine according to the present invention further includes an extra lottery means for lottering the number of extra games in the specific game state based on the internal winning combination determined during the operation of the specific game state and the game mode. It has a configuration.

  With this configuration, the gaming machine according to the present invention has the number of remaining games in the specific gaming state when the special stock holding means wins the small role on condition that the predetermined small role is won during the operation of the specific gaming state. And the game mode at the time of winning the small role is held as a special stock. In addition, on the condition that the number of games in the specific game state has reached a predetermined number of games, the specific game state return means returns the specific game state for the remaining number of games held in the special stock holding means. At this time, the specific game state return means returns the game mode held in the special stock holding means as the game mode. That is, a special stock that fluctuates according to the number of games and the game state when a predetermined small combination is won is added to the specific game state.

  Therefore, the profit given to the player by adding the specific game state can be changed according to the number of games and the game state at the time of a predetermined small role winning. For this reason, the profit given to the player during the operation of the specific gaming state does not become monotonous. As a result, the gaming machine according to the present invention can improve the interest of the player as compared with the conventional game with respect to the addition of a specific gaming state advantageous to the player such as ART.

  In the gaming machine according to the present invention, the special stock holding means may change the second game mode to the special stock only when the game mode is the second game mode when the predetermined small combination is won. It has the structure hold | maintained as.

  With this configuration, the gaming machine according to the present invention holds the second game mode as a special stock only when the game mode is in the second game mode when a predetermined small combination is won. For this reason, when the game mode when the number of games in the specific game state reaches the predetermined number of games is the first game mode, the game mode can be returned to the second game mode again. When is in the second game mode, the second game mode can be continued. That is, when the game mode at the time of winning a predetermined small role is the first game mode, it is not held, so the game mode is the second game mode when the specific game state related to the special stock is restored. In some cases this can be continued. In this way, since a game mode that is relatively unfavorable for the player is not maintained, only a profit advantageous to the player can be given regarding the addition of the specific game state.

  Furthermore, in the gaming machine according to the present invention, the game mode control means sets the game mode to the second game with the predetermined end condition that the number of games in the second game mode has reached a predetermined game number. When the number of remaining games in the second gaming mode is smaller than the number of remaining games in the specific gaming state, the special stock holding means shifts from the gaming mode to the first gaming mode. The number of remaining games in the second game mode at the time of winning the small role is held as the special stock, and the specific state return means is provided on the condition that the number of games in the specific game state has reached the predetermined number of games. In addition, the specific game state corresponding to the number of remaining games in the second game mode held in the special stock holding means is returned.

  With this configuration, the gaming machine according to the present invention allows the second gaming mode of the predetermined small role to be won when the number of remaining games in the second gaming mode is smaller than the number of remaining games in the specific gaming state. Hold the number of remaining games as a special stock. Therefore, the number of games in a specific gaming state that are returned as special stock can be made to depend on the number of remaining games in the second gaming mode when a predetermined small role is won. Thus, for example, when the game mode is the first game mode when a predetermined small role is won, the special stock can be prevented from being held, and a specific game can be selected according to the game mode when the predetermined small role is won. Changes can be made to the benefits given to the player during the operation of the state.

  According to the present invention, it is possible to provide a gaming machine that can improve the interest of a player as compared to the conventional art with respect to the addition of a specific gaming state that is advantageous to a player such as a so-called ART.

  A pachislot machine which is an example of a gaming machine according to the present invention will be described below with reference to the drawings.

[Function flow of pachislot machine]
As shown in FIG. 1, when a medal is inserted by the player and the start lever 16 is operated, the pachislot machine 1 has one value from a random number in a predetermined numerical range (for example, 0 to 65535). (Hereinafter, random value) is extracted.

  The winning combination determining means (main CPU 73 described later) performs lottery based on the extracted random number value and determines the internal winning combination. In other words, the winning combination determining means determines whether the start switch 57 (see FIG. 6) detects the start operation of the unit game for the start lever 16 (establishment of a predetermined start condition) with a predetermined probability among a plurality of combinations. Determine the winning role. By determining the internal winning combination, a combination of symbols that permits display along the winning determination lines 8a and 8b (see FIG. 2) described later is determined. The types of symbol combinations include those related to “winning” in which benefits such as payout of medals, replay (replay) operation, bonus operation, etc. are given to the player, and other so-called “losing” Such a thing is provided. Those related to “winning” are a combination of symbols associated with transition of the gaming state managed by the main control circuit 71. Includes a small role involved (eg watermelon).

  Subsequently, after the plurality of reels 3L, 3C, 3R are rotated, when the stop button 17L, 17C, 17R is pushed by the player, the stop control means includes the internal winning combination and the stop buttons 17L, 17C, Based on the timing at which the 17R is pressed, control is performed to stop the rotation of the corresponding reels 3L, 3C, 3R.

  Here, in the pachi-slot machine 1, basically, control for stopping the rotation of the corresponding reels 3L, 3C, 3R is performed within a specified time from when the stop buttons 17L, 17C, 17R 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 the number of four symbols (the maximum number of sliding symbols). ).

  When the internal winning combination permitting the display of the symbol combination related to winning is determined, the stop control means uses the specified time to determine whether the symbol combination is a winning determination line 8a, 8b as an effective line. The rotation of the reels 3L, 3C, 3R is stopped within the range of the maximum number of sliding pieces so as to be displayed as much as possible along (see FIG. 2). On the other hand, combinations of symbols that are not permitted to be displayed by the internal winning combination are not displayed along the winning determination lines 8a and 8b (see FIG. 2) using the specified time. The rotation of the reels 3L, 3C, 3R is stopped within the range of the maximum number of sliding pieces.

  Thus, when the rotation of the plurality of reels 3L, 3C, 3R is all stopped, the display combination determining means (main CPU 73 described later) displays the symbols displayed along the winning determination lines 8a, 8b (see FIG. 2). It is determined whether or not the combination is related to winning. That is, the display combination determining means determines whether or not the combination is established based on the combination of symbols stopped on the winning determination lines 8a and 8b, based on the fact that the change of the symbols is stopped by the stop control means. When it is determined that the prize is related to a prize, a bonus such as a medal payout is given to the player. When the symbols displayed along the winning determination lines 8a and 8b (see FIG. 2) are the replaying roles and RT transition symbols of replays 2 to 5 among those related to winning, they are shown in FIG. 9 to be described later. Transition between different gaming states. However, for the transition from the RT2 gaming state to the RT3 gaming state, winning is not a condition but a winning condition. A series of flows as described above is performed as one game (unit game) in the pachislot machine 1.

  Further, in the pachislot machine 1, in the series of flows described above, video display performed by the liquid crystal display device 10, light output performed by the lamp (LED) 20, and sound output performed by the speakers 48L, 48R, 49L, and 49R. Alternatively, various effects are performed using these combinations. In addition, a notification sound corresponding to the winning combination is output from the speakers 48L, 48R, 49L, 49R. This notification sound is output when the stop buttons 17L, 17C, and 17R are pressed. Thereby, the effect performed after the operation of the stop buttons 17L, 17C, and 17R ends and the notification sound do not compete with each other.

  When the start lever 16 is operated by the player, an effect random number value (hereinafter referred to as an 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 (main CPU 73 or sub CPU 82 described later) determines by lottery what is to be executed this time from a plurality of types of effect contents associated with the internal winning combination. To do.

  When the content of the effect is determined, the effect means (the liquid crystal display device 10 described later, the speakers 48L, 48R, 49L, 49R described later, and the lamp (LED) 20 described later) starts to rotate the reels 3L, 3C, 3R. When the rotation of the reels 3L, 3C, and 3R is stopped, the execution of the effects is advanced in conjunction with each opportunity such as when the determination of the presence or absence of a prize is made. A part of the performance is executed on condition that a bet button (MAXBET button 12, 1BET button 14) as an operation means is operated. When the internal winning combination is a small combination 1 to 3, the directing means informs the left reel 3L whether the symbol to be stopped is red 7, blue 7 or yellow 7, and the bet button (MAXBET Notification is made to prompt the user to operate the button 12 and the 1BET button 14). In this way, in the pachislot machine 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. To improve the player's interest.

<Main control circuit>
Next, the main control circuit 71 constituted by the main control board 31 will be described with reference to FIG. FIG. 7 is a block diagram illustrating a configuration example of the main control circuit 71 of the pachislot machine 1.

  The main control circuit 71 includes a microcomputer 72 installed on the main control board 31 as a main component. The microcomputer 72 includes a main CPU 73, a main ROM 74, and a main RAM 75.

  The main ROM 74 stores a control program executed by the main CPU 73, a data table, data for transmitting various control commands (commands) to the sub control circuit 81, and the like. The main RAM 75 is provided with a storage area for storing various data such as an internal winning combination determined by executing the control program.

  The main CPU 73 is connected with a clock pulse generation circuit 76, a frequency divider 77, a random number generator 78 and a sampling circuit 79. The clock pulse generation circuit 76 and the frequency divider 77 generate clock pulses. The main CPU 73 executes a control program based on the generated clock pulse. The random number generator 78 generates a random number in a predetermined range (for example, 0 to 65535). The sampling circuit 79 extracts one value from the generated random numbers.

  The main CPU 73 counts the number of times pulses are output to the stepping motors of the reels 3L, 3C, and 3R after detecting the reel index. Thereby, the main CPU 73 manages the rotation angle of each reel 3L, 3C, 3R (mainly, how many symbols the reel has rotated).

  Here, management of the rotation angles of the reels 3L, 3C, and 3R will be specifically described. The number of pulses output to the stepping motor is counted by a pulse counter provided in the main RAM 75. Each time the output of a predetermined number of pulses (for example, 16 times) necessary for rotation for one symbol is counted by the pulse counter, the symbol counter provided in the main RAM 75 is incremented by one. The symbol counter is provided for each reel 3L, 3C, 3R. The value of the symbol counter is cleared when the reel index is detected by the reel position detection circuit 38b (see FIG. 6).

  In other words, in the present embodiment, by managing the symbol counter, it is possible to manage how many symbols have been rotated since the reel index was detected. Therefore, the position of each symbol on each reel 3L, 3C, 3R is detected with reference to the position where the reel index is detected.

  As described above, in the present embodiment, the maximum number of sliding symbols is set to four symbols. Therefore, when the left stop button 17L is pressed, the symbols of the left reel 3L in the middle of the left display window 4L and the symbols within the range up to the four symbols ahead are displayed in the middle of the left display window 4L. It becomes a symbol that can be stopped.

<Sub control circuit>
Next, the sub control circuit 81 constituted by the sub control board 41 will be described with reference to FIG. FIG. 8 is a block diagram illustrating a configuration example of the sub control circuit 81 of the pachislot machine 1.

  The sub control circuit 81 is electrically connected to the main control circuit 71 and performs processing such as determination and execution of effect contents based on a command transmitted from the main control circuit 71. The sub control circuit 81 basically includes a sub CPU 82, a sub RAM 83, a rendering processor 84, a drawing RAM 85, and a driver 86.

  The sub CPU 82 controls the output of video, sound and light according to the control program stored in the ROM cartridge substrate 61 in accordance with the command transmitted from the main control circuit 71. The ROM cartridge substrate 61 basically includes a program storage area and a data storage area.

  A control program executed by the sub CPU 82 is stored in the program storage area. For example, in the control program, a main board communication task for controlling communication with the main control circuit 71 and an effect registration task for extracting effect random numbers and determining and registering effect contents (effect data) Is included. Further, a drawing control task for controlling display of an image by the liquid crystal display device 10 (see FIG. 6) based on the determined effect content, a lamp control task for controlling light output by the lamp (LED) 20, speakers 48L, 48R, An audio control task for controlling sound output by 49L and 49R is included.

  The data storage area includes a storage area for storing various data tables, a storage area for storing effect data constituting each effect content, and a storage area for storing animation data related to creation of video. Also included are a storage area for storing sound data related to BGM and sound effects, a storage area for storing lamp data related to the light on / off pattern, and the like.

  The sub-RAM 83 is provided with a storage area for registering the determined contents and effects data, and a storage area for storing various data such as an internal winning combination transmitted from the main control circuit 71.

  The sub CPU 82, the rendering processor 84, the drawing RAM (including the frame buffer) 85, and the driver 86 create a video in accordance with the animation data designated by the contents of the effect, and cause the liquid crystal display device 10 to display the created video.

  In addition, the sub CPU 82 causes the speakers 48L, 48R, 49L, and 49R to output sounds such as BGM according to the sound data specified by the production contents. Further, the sub CPU 82 controls turning on and off of the lamp (LED) 20 according to the lamp data designated by the contents of the effect.

  The sub control board 41 is housed in the sub control board case 42. The sub-control board case 42 has a plated portion formed on the entire outer surface of the case main body, so that the cost can be reduced as compared with the case where a radio wave blocking sheet is used.

[Main game state transition]
As shown in FIG. 9, in the pachislot machine 1, the gaming state controlled by the main control circuit 71 includes the general gaming state (RT0 gaming state), the RT1 gaming state, the RT2 gaming state, the RT3 gaming state, and the bonus gaming. There is a state.

  The general gaming state (RT0 gaming state) is a gaming state in which an internal winning combination is lottered with the lottery value described in the column of the general gaming state in FIG. 14, and is a replay low probability state in which the winning probability of Replay 1 is low. In this general gaming state, the re-game player is not internally won for replays 2 to 5 related to the transition of the gaming state, and is internally won only for the replay 1 not related to the gaming state transition. The replay 1 is a so-called normal replay, and is displayed as “replay-replay-replay” as a combination of symbols.

  The general gaming state shifts from the bonus gaming state or the RT1 gaming state. The general gaming state shifts from the bonus gaming state by the end of the bonus gaming state, and shifts from the RT1 gaming state by displaying a symbol corresponding to the replay 5 (winning). As shown in FIG. 13, in the case of replay 5, when replays 2 to 4 and replay 5 are overlapped (winning numbers 2 to 4), the display design corresponding to replays 2 to 4 in which the display design of the left reel is internally won If not, that is, stop operation of the stop buttons 17L, 17C, 17R at the position where the 7 symbols corresponding to the winning combination are not drawn out of the 7 symbols ("Red 7", "Blue 7", "Yellow 7") This is a replay that is stopped and displayed.

  The RT1 gaming state is a gaming state in which an internal winning combination is lottered with the lottery value described in the RT1 gaming state column in FIG. 14, and is a replay low-probability state as compared to the RT2 gaming state. In this RT1 gaming state, regarding the re-gamer, the replay 1 that is not related to the game state transition is not internally won, and the replay 5 and the replay 5 that are related to the game state transition are overlapped. Replays 2 to 4 are so-called promoted replays and have a higher drawing priority than replay 5. There are three types of replays 2-4, "Red 7-Replay-Replay", "Blue 7-Replay-Replay", and "Yellow 7-Replay-Replay". ing. The replay 5 is a so-called demoted replay, and is displayed as “bell-replay-replay” as a combination of symbols.

  The RT1 gaming state is shifted by displaying the RT transition symbol in the general gaming state or the RT2 gaming state. As shown in FIG. 13, the RT transition symbol is a missed portion of small roles 1 to 3 which is a three-choice bell, and the symbol combination is displayed as “Replay-Bell-Bell”. That is, when the RT transition symbol is the internal winning combination (winning numbers 5 to 7) for the small winning combinations 1 to 3, if the display symbol of the left reel is not the display symbol corresponding to the small winning combination 1 to 3 that is internally winning, that is, 3 Stop display when the stop button 17L, 17C, 17R is operated to stop at the position where the 7 symbols corresponding to the winning combination are not drawn out of the 7 symbols ("Red 7", "Blue 7", "Yellow 7") It is a losing eye.

  The RT2 gaming state is a gaming state in which an internal winning combination is lottery with the lottery value described in the RT2 gaming state column in FIG. In the RT2 gaming state, with respect to the re-gamer, internal winning is not performed for replays 2 to 4 but only replay 1 is internally won. The RT2 gaming state is a replay high probability state in which the lottery value of Replay 1 is higher (approximately 6.2 times) than the general gaming state. This RT2 gaming state shifts by displaying a symbol combination corresponding to replays 2 to 4 in the RT1 gaming state. In the RT2 gaming state, the sub-side enters the AT gaming state by the specified number selected in the first game that has shifted to the AT gaming state. That is, in the RT2 gaming state on the main side, the ART side is in the ART state while the sub side is in the AT state. Such an ART state constitutes a specific gaming state and is realized by the main CPU 73 and the sub CPU 82.

  The RT3 gaming state is a gaming state in which an internal winning combination is lottery with the lottery value described in the RT3 gaming state column in FIG. In this RT3 gaming state, with respect to the re-game player, internal winning is not performed for replays 2 to 4 but only replay 1 is internally won. The RT3 gaming state is a replay low probability state in which the lottery value of Replay 1 is higher (1.5 times) than the general gaming state but lower than the RT2 gaming state. This RT3 gaming state shifts when a bonus (BB or RB) is won internally in the general gaming state, the RT1 gaming state, or the RT2 gaming state (the gaming state surrounded by a broken line in FIG. 9).

  Here, the RT1 gaming state, the RT2 gaming state, and the RT3 gaming state are not RTs for managing the number of games, and transition to other gaming states only when the transition condition is satisfied. In that sense, the RT1 gaming state, the RT2 gaming state, and the RT3 gaming state are infinite RTs.

  The bonus game state is a game state advantageous for the player, and includes a BB game state corresponding to the display combination “BB” and an RB2 game state corresponding to the display combination “RB”. In the BB gaming state, the RB1 gaming state is executed. Therefore, the bonus game state includes the BB game state, the RB1 game state, and the RB2 game state. Such a bonus game state constitutes a special game state and is realized by the main CPU 73. The main CPU 73 for operating the bonus game state constitutes a special game state operating means.

  Further, in this bonus gaming state, an internal winning combination is lottery in the RB1 gaming state internal lottery table of FIG. 15 or the RB2 gaming state internal lottery table of FIG. The bonus game state is shifted to the bonus game (BB or RB) through the RT3 game state on condition that the bonus has been won internally and winning in the RT3 game state (see FIG. 9). There are two types of bonus game states, RB1 game state and RB2 game state, depending on the combination of symbols when the bonus game state is entered.

  The RB1 gaming state is a gaming state that shifts when the symbol combination is “red 7-red 7-red 7” (see FIG. 12). This RB1 gaming state is a gaming state in which two medals are inserted, and the internal winning combination is lottery based on the RB1 gaming state internal lottery table of FIG. In this RB1 gaming state, each of the small roles 4 to 15 is won alone, or the small roles 1 to 15 and the watermelon are repeatedly won. Therefore, in the RB1 gaming state, when any of the small roles 4 to 15 is won internally, if there is no navigation, 15 payouts with a probability of 1/27 (the symbol combination table of FIG. 12) In the case of the internal winning combination of the small roles 1 to 15 and the watermelon, it is necessary to pay out 15 pieces (in the symbol combination table of FIG. 12). (Refer to “Number of inserted sheets: 2”). The RB1 gaming state is ended by winning a small role 8 times or 12 times. However, the RB1 gaming state is repeatedly performed until there is a payout of medals exceeding a predetermined number (for example, a payout of medals exceeding 390).

  The RB2 gaming state is a gaming state that shifts when the symbol combination is “blue 7-blue 7-blue 7” (see FIG. 12). This RB2 gaming state is a gaming state in which two medals are inserted, and an internal winning combination is lottery based on the RB2 gaming state internal lottery table of FIG. In this RB2 gaming state, the small roles 1 to 15 and the watermelon are won in duplicate. Therefore, in the RB2 gaming state, the player can always receive 15 payouts (refer to “insertion number: 2” of the payout number in the symbol combination table in FIG. 12) regardless of the operation timing of the stop buttons 17L, 17C, 17R. it can. The RB2 gaming state is terminated by winning a small role eight times or by eight games.

[Various data tables on the main side]
10 to 21 are various data tables stored in the main ROM 74.

<Pattern arrangement table>
The symbol arrangement table shown in FIG. 10 represents the arrangement of symbols arranged on the surface of each of the left reel 3L, the middle reel 3C, and the right reel 3R by data. The symbol arrangement table defines the correspondence between 21 symbol positions “0” to “20” and symbols corresponding to these symbol positions. Symbol positions “0” to “20” indicate the positions of symbols arranged along the rotation direction in each of the left reel 3L, the middle reel 3C, and the right reel 3R. The symbols corresponding to the symbol positions “0” to “20” can be specified by referring to the symbol arrangement table using the value of the symbol counter. The types of symbols include “red 7”, “blue 7”, “yellow 7”, “watermelon”, “bell”, and “replay”.

  “Red 7”, “Blue 7”, and “Yellow 7” (hereinafter, these may be collectively referred to as “7 symbols”) are arranged at intervals of 6 frames on each reel 3L, 3C, 3R. Regardless of the timing at which the stop buttons 17L, 17C and 17R are operated, any one of “red 7”, “blue 7” and “yellow 7” can be stopped and displayed on the winning determination lines 8a and 8b. ing. Therefore, when the internal winning combination is replay 2-4 (3 choice replay) or small combination 1-3 (3 choice bell), by operating the stop buttons 17L, 17C, 17R at an appropriate timing, It is possible to win an internal winning combination. For example, for the replay 2 and the small role 1, the display symbol of the left reel 3L is “red 7”, but the watermelon whose symbol position data is No. 1 from the replay whose symbol position data is No. 16 is in the middle of the left reel 3L. If the stop button 17L is operated when positioned, “red 7” stops at the upper or lower stage defining the winning determination lines 8a and 8b in the left reel 3L, and the replay 2 and the small part 1 can be won. Become. Similarly, with respect to the replay 3 and the small role 2, if the stop button 17L is operated when the watermelon whose symbol position data is No. 8 from the replay whose symbol position data is No. 2 is positioned in the middle stage of the left reel 3L, the winning determination is made. “Blue 7” stops at the upper or lower stage defining the lines 8a and 8b, and it becomes possible to win the replay 3 and the small role 2, and for the replay 4 and the small role 3, the replay whose symbol position data is No. 9 If the stop button 17L is operated when the watermelon whose symbol position data is No. 15 is located in the middle stage of the left reel 3L, “Yellow 7” stops at the upper stage or the lower stage defining the winning determination lines 8a and 8b and is replayed. 4 and small role 3 can be won. In other words, if the middle stage of the left reel 3L is considered as a reference for the stop operation, the symbol position data Nos. 16 to 1 are the “red 7” stop region, the symbol position data Nos. 2 to 8 are the “blue 7” stop region, Symbol position data No. 9 to No. 15 are “yellow 7” stop areas.

  Since “watermelon”, “bell”, and “replay” are arranged at intervals of two or three frames in each reel 3L, 3C, 3R, the stop button 17L, 17C, 17R is operated at any timing. Can be stopped at the winning determination lines 8a and 8b. Each symbol arranged on each reel 3L, 3C, 3R is defined by the symbol code shown in FIG. 8, and is distinguished by 1-byte (8-bit) data.

  The symbol arrangement table shown in FIG. 10 assigns the symbol located in the middle stage of the display windows 4L, 4C, 4R (the symbol passing through the middle stage of the display window) to the symbol position “0” when the reel index is detected. A correspondence relationship in which symbol positions “0” to “20” are assigned to each of the 21 symbols in the order of movement in the reel rotation direction is defined. In this way, by specifying the middle stage of the display windows 4L, 4C, and 4R as a reference, the type of symbol positioned in the middle stage of the display windows 4L, 4C, and 4R is specified for each of the three reels 3L, 3C, and 3R. Can do.

<Design code table>
In the symbol code table shown in FIG. 11, codes for specifying symbols arranged on the surfaces of the three reels 3L, 3C, and 3R are stored. As described above, the symbols used in the pachislot machine 1 according to the present embodiment are six types of “red 7”, “blue 7”, “yellow 7”, “watermelon”, “bell”, and “replay”.

  In the symbol code table, “00000001” is assigned as data to the “red 7” symbol (symbol code 1). “00000010” is assigned as data to the “blue 7” symbol (symbol code 2). “00000011” is assigned as data to the “yellow 7” symbol (symbol code 3). “00000100” is assigned as data to the “watermelon” symbol (symbol code 4). For the “bell” symbol (symbol code 5), “00000101” is assigned as data. “00000110” is assigned as data to the “replay” symbol (symbol code 6).

<Design combination table>
The symbol combination table shown in FIG. 12 defines a correspondence relationship between symbol combinations, winning action flags, and payout numbers.

  In the pachi-slot machine 1 according to the present embodiment, the symbol combinations arranged along the activated winning determination lines 8a and 8b are to be determined for winning or operating. That is, it is determined whether or not the combination of symbols arranged along the activated winning determination lines 8a and 8b (see FIG. 2) matches a predetermined combination of symbols. This predetermined symbol combination is a symbol combination defined in the symbol combination table. If the combination of symbols arranged along the activated winning determination lines 8a and 8b matches the predetermined symbol combination, the medal payout, the re-game operation, the bonus game operation, or the game state Transition etc. are performed.

<Pattern combination>
The symbol combinations are a combination of the upper symbol of the left reel 3L, the middle symbol of the middle reel 3C, and the lower symbol of the right reel 3R, and the lower symbol of the left reel 3L and the middle symbol of the middle reel 3C. And the upper symbol of the right reel 3R. As described above, it is determined whether or not the symbol combination in the symbol combination table matches the symbol combination lined up along the winning determination lines 8a and 8b that are descending to the right or rising to the right. The combination (display combination) that is the target of winning determination is “replay combination”, “small combination”, “watermelon”, and “bonus combination”.

  The “replay combination” is a combination in which a game with the same number of medals as the medals inserted for playing a game can be performed without inserting a new medal, and the number of payouts at the time of winning determination is zero. The “replay role” includes “replay 1”, “replay 2”, “replay 3”, “replay 4”, and “replay 5”.

  “Replay 1” is a normal replay in which a winning determination is made when “replay-replay-replay” is arranged along the winning determination lines 8a and 8b.

  “Replay 2”, “Replay 3”, and “Replay 4” are replay roles for which a winning determination is made when the 7 symbols of the left reel 3L are correct, respectively, along the winning determination lines 8a and 8b. This is a promotion replay in which a winning determination is made when “Replay-Replay”, “Blue 7-Replay-Replay”, and “Yellow 7-Replay-Replay” are lined up. These “Replay 2”, “Replay 3” and “Replay 4” do not win at the same time, and the display pattern on the left reel 3L is any of “Red 7”, “Blue 7” and “Yellow 7”. It is different in that there is. In the left reel 3L, as described above, “Red 7”, “Blue 7”, and “Yellow 7” are arranged at intervals of 6 frames, and “Red 7”, “Blue 7”, and “Yellow 7” Either of them can be displayed on the winning determination lines 8a and 8b. Therefore, “Replay 2”, “Replay 3”, and “Replay 4” are three-choice replays in a situation where there is no notification regarding the type of 7 symbols of the left reel 3L.

  “Replay 5” is a demoted replay in which a winning determination is made when “Bell-Replay-Replay” is arranged along the winning determination lines 8a and 8b. This “Replay 5” is won simultaneously with “Replay 2”, “Replay 3” or “Replay 4”. As will be described later with reference to FIG. 20A, “Replay 5” has a lower priority of drawing than “Replay 2”, “Replay 3”, and “Replay 4”. Therefore, “Replay 5” is displayed when “Replay 2”, “Replay 3”, or “Replay 4” is missed.

  The “small roles” are small roles 1 to 3 with 15 payouts when the number of inserted medals is 3, and small roles 4 to 15 with 1 payout when the number of inserted medals is 3. Is included.

  The small roles 1 to 3 are bells that are determined to receive a prize when the 7 symbols of the left reel 3L are correct, and “red 7-bell-bell” and “blue 7--” are respectively determined along the winning determination lines 8a and 8b. “Bell-Bell” and “Yellow 7-Bell-Bell” are three-choice bells that are determined to win. When these small combinations 1 to 3 are won internally and the seven symbols corresponding to the respective small combinations 1 to 3 cannot be stopped on the left reel 3L, the display combination becomes an RT transition symbol. This RT transition symbol is a loser in which “Replay-Bell-Bell” is displayed side by side along the winning determination lines 8a, 8b, and shifts the gaming state to the RT1 gaming state. That is, when the RT transition symbol is a display combination in the general gaming state, the gaming state transitions (promotion) to the RT1 gaming state, and when the RT transition symbol is the display combination in the RT2 gaming state, the gaming state is RT1 gaming. Transition to status (demotion).

  Each of the small roles 4 to 15 is a single combination for which a winning determination is made when seven different colored symbols are arranged along the winning determination lines 8a and 8b. Specifically, the small role 4 is “red 7-blue 7-blue 7”, the small role 5 is “red 7-blue 7-yellow 7”, and the small role 6 is “red 7-yellow 7-blue 7”. ”, Small role 7 is“ red 7-yellow 7-yellow 7 ”, small role 8 is“ blue 7-red 7-red 7 ”, and small role 9 is“ blue 7-red 7-yellow 7 ”. The small role 10 is “blue 7-yellow 7-red 7”, the small role 11 is “blue 7-yellow 7-yellow 7”, and the small role 12 is “yellow 7-red 7-red 7”. The winning combination is “yellow 7-red 7-blue 7”, the small role 14 is “yellow 7-blue 7-red 7”, and the small role 15 is “yellow 7-blue 7-blue 7”. A winning determination is made when they are lined up along the lines 8a, 8b.

  “Watermelon” is determined to be awarded when watermelons are arranged along the winning decision lines 8a and 8b.

  The “bonus combination” is determined to be awarded when seven symbols of the same color are arranged along the winning determination lines 8a and 8b, and includes “BB” and “RB” as display combinations.

  The display combination “BB” is determined to be awarded when “red 7-red 7-red 7” are arranged along the winning determination lines 8a and 8b. The display combination “BB” is used to enter the BB gaming state. Be migrated. This BB gaming state continues until, for example, a predetermined total number of paid-out medals exceeds a predetermined number (for example, 390). When transitioned to this BB gaming state, transition to the RB1 gaming state is made. This RB1 game state continues until, for example, a predetermined number of winnings (for example, 8 times) is reached or until a predetermined number of unit games (for example, 12 times) are played. In the BB gaming state, the RB1 gaming state is repeated until the total payout number of medals exceeds a predetermined number (for example, 390), and ends when the total payout number of medals exceeds the number (for example, 390).

  The display combination “RB” is determined to be awarded when “blue 7-blue 7-blue 7” is arranged along the winning determination lines 8a and 8b, and the RB game is activated by the display combination “RB”. Then, the RB2 gaming state is entered. This RB2 gaming state continues until, for example, a predetermined number of winnings (for example, 8 times) is reached or until a predetermined number of unit games (for example, 12 times) are performed. However, in the internal lottery table for the RB2 gaming state shown in FIG. 16, since the small roles 1 to 15 and the watermelon are always won, the RB2 gaming state is substantially equal to a predetermined number of winnings (for example, 8 times). It ends by reaching.

<Winning action flag>
The winning action flag is data assigned in correspondence with a combination of unique symbols to indicate a display combination, and includes 1 byte (8 bits) data and a storage area type. The storage identification data is data for distinguishing 1-byte data. One-byte data includes data related to a combination of a plurality of symbols. Each symbol combination (display combination) is distinguished by storage area identification data and 1-byte data.

  In the present embodiment, as shown in FIG. 12, since there are more than 8 types of symbol combinations, all symbol combinations are specified only by 1 byte (8 bits) of data constituting the winning action flag. Cannot be identified or identified. For this reason, in this embodiment, 1-byte data is distinguished using storage area types 1 to 3 (see FIG. 19A). By doing this, even if the value of 1-byte data is the same, by specifying any one of the storage area identification data 1 to 3, combinations of more than 8 types of symbols Can be treated as a combination.

  Storage area type 1 is assigned to replays 1 to 5 and small roles 1 to 3 for the display combination, and storage area type 2 is assigned to small combinations 4 to 11 for the display combination. ˜15, storage area type 3 is assigned to watermelon, BB, RB and RT transition symbols. For 1-byte data, for the assigned storage area type, the bit corresponding to each display combination is set to “1”, and the remaining bits are set to “0”.

  For example, by setting the storage area type value to “1” and the 1-byte data value to “00000100”, the display combination “replay” can be designated, and the storage area type value is set to “3”. By setting the value of 1-byte data to “10000000”, the display combination “RT transition symbol” can be designated.

<Number of payouts>
The number of payouts is data indicating the number of medals to be paid out to the player corresponding to each combination of symbols. When the combination of symbols arranged along the winning determination lines 8a and 8b matches the “combination of symbols” in the symbol combination table, the medals are discharged or credited by driving the hopper device 34 based on the corresponding payout number. Counter addition is performed. The number of payouts for the replay combination is 0, the number of payouts for the 3 choice bell is 15, and the number of payouts for the single option is 1 when the insertion number is 3, and the insertion number is 2 (RB1 gaming state and RB2 gaming) Status), the number of watermelons to be paid out is 6 when the inserted number is 3, and 15 when the inserted number is 2 (RB1 gaming state and RB2 gaming state), the bonus combination payout number Is 0.

<Indication of winning prizes>
FIG. 13 is a diagram showing the relationship between the pressed position and the winning combination of replay / pocket. In addition, the correct position in FIG. 13 refers to a position where a target symbol can be stopped on the winning determination lines 8a and 8b within a range of four-slip which is the maximum number of sliding symbols. Further, “-” in FIG. 13 means that the target symbol can be stopped regardless of the stop operation timing.

  In the winning number 1, the internal winning combination is replay 1, and the replay 1 wins the winning determination lines 8a and 8b regardless of the stop operation positions of the reels 3L, 3C, and 3R.

  In the case of winning number 2, the internal winning combination is replay 2 and replay 5, and when replay 2 can stop red 7 at the correct position of the left reel 3L (at the time of correct answer), the priority draw ranking is higher than replay 5 Replay 2 wins. On the other hand, when red 7 cannot be stopped at the correct position of the left reel (at the time of incorrect answer), replay 5 wins.

  In the case of winning number 3, the internal winning combination is Replay 3 and Replay 5, and when this Replay 3 can stop Blue 7 at the correct position of the left reel 3L (at the correct answer), it has a higher priority pull-in order than Replay 5 Replay 3 wins. On the other hand, when Blue 7 cannot be stopped at the correct position of the left reel (at the time of incorrect answer), Replay 5 wins.

  In the case of winning number 4, the internal winning combination is replay 4 and replay 5, and when this replay 4 can stop yellow 7 at the correct position of the left reel 3 </ b> L (at the time of correct answer), the priority draw ranking is higher than replay 5. Replay 4 wins. On the other hand, when yellow 7 cannot be stopped at the correct position of the left reel (when incorrect), replay 5 wins.

  In the case of winning number 5, the internal winning combination is a small combination 1, and this small combination 1 wins when red 7 can be stopped at the correct position of the left reel 3L (at the time of correct answer). On the other hand, when the red 7 cannot be stopped at the correct position of the left reel 3L (when the answer is incorrect), the RT transition symbol (“Replay-Bell-Bell”) stops as a missed spot.

  The winning number 6 is that the internal winning combination is the small combination 2, and this small combination 2 wins when the blue 7 can be stopped at the correct position of the left reel 3L (when correct). On the other hand, when Blue 7 cannot be stopped at the correct position of the left reel 3L (at the time of incorrect answer), the RT transition symbol (“Replay-Bell-Bell”) stops as a missed spot.

  In the winning number 7, the internal winning combination is a small combination 3, and this small combination 3 wins when yellow 7 can be stopped at the correct position of the left reel 3L (when correct). On the other hand, when the yellow 7 cannot be stopped at the correct position of the left reel 3L (at the time of incorrect answer), the RT transition symbol (“Replay-Bell-Bell”) stops as a missed eye.

  The internal winning combinations of the winning numbers 8 to 19 are the small combinations 4 to 15, respectively. These small combinations 4 to 15 correspond to the display positions of the internal winning combinations at the correct positions of the reels 3L, 3C, and 3R. Win when the symbol can be stopped (at the right time). On the other hand, if any one of the reels 3L, 3C, and 3R cannot stop the correct seven symbols at the correct position (at the time of incorrect answer), the losing eye stops.

  The winning number 20 is a watermelon with an internal winning combination, and this watermelon is won at the correct position of each reel 3L, 3C, 3R when the watermelon can be stopped (at the time of correct answer). The watermelon also stops when the correct watermelon cannot be stopped at the correct position of each of the reels 3L, 3C, and 3R (during incorrect answer). In other words, since the watermelons are arranged at intervals of two or three frames on each of the reels 3L, 3C, and 3R, it is possible to win regardless of whether the stop position is correct or incorrect.

  In the present embodiment, on the main side, “watermelon” is determined as an internal winning combination during the so-called ART, which is defined as a specific gaming state that is advantageous to the player and different from the bonus gaming state. The value of the ART game number counter (art remaining game number) when the sub-side internally wins “Watermelon” and the game mode (high probability mode or low probability mode) at the time of the internal win are sub The data is stored in the sub RAM 83 by the CPU 82. The sub CPU 82 and the sub RAM 83 constitute special stock holding means.

<Internal lottery table>
14 is an internal lottery table for the non-bonus gaming state, FIG. 15 is an internal lottery table for the RB1 gaming state, and FIG. 16 is an internal lottery table for the RB2 gaming state. These internal lottery tables are tables that define lottery values and data pointers for each gaming state in correspondence with winning numbers.

  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 dake pointer) to which it is assigned will be determined. When the number of processes for determining whether or not the result of subtraction has become negative exceeds a predetermined maximum number, the result of the internal lottery process is “lost”.

  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)”. In the present embodiment, by using a plurality of types of internal lottery tables, the type of internal winning combination to be determined and the winning probability are changed, and as a result, the player's expectation is undulated.

  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. That is, the data pointer is data used to determine the storage area type and 1-byte data in the small role replay winning combination determination table shown in FIG. 17 and the bonus internal winning combination determination table shown in FIG. For the data pointer, a small role / replay data pointer and a bonus data pointer are individually defined corresponding to each of the plurality of winning numbers.

  As shown in FIG. 14, the non-bonus gaming state internal lottery table defines lottery values for the general gaming state, the RT1 gaming state, the RT2 gaming state, and the RT3 gaming state. In these gaming states, the lottery values of replays 1 to 5 are different, and the lottery values of the small roles 1 to 15, BB, and RB are the same. In the general gaming state, the RT2 gaming state, and the RT3 gaming state, there is no lottery value sorting in Replay 1, but there is no sorting of Replays 2 to 4 (Replay 5). On the other hand, in the RT1 gaming state, although replays 2 to 4 (replay 5) have lottery value distribution, there is no replay 1 distribution. Regarding Replay 1, the lottery value increases in the order of the RT2 gaming state, the RT3 gaming state, the general gaming state, and the RT1 gaming state.

  Here, regarding the data points for the small role / replay, “1” to “20” coincide with the winning numbers. On the other hand, regarding bonus data points, “0” is lost, “1” is BB, and “2” is RB. Accordingly, the winning numbers 21 to 32 are the overlapping winnings of the small roles 1 to 15 and the bonus, and the winning numbers 33 and 34 are the single winnings of the bonus.

  As shown in FIG. 15, the internal lottery table for RB1 gaming state is a lottery table in the RB1 gaming state in the BB gaming state. In this RB1 gaming state internal lottery table, the winning number 1 is the small winning combination 1-15 of the data pointer 21 and the duplicate winning of the watermelon, and the winning numbers 2-13 are the single winning combination of the small winning combination 4-15. In other words, in the RB1 gaming state of the BB gaming state, all of the small roles 1 to 15 and the watermelon are won in duplicate, or any of the small roles 4 to 15 is won alone.

  As shown in FIG. 16, the internal lottery table for RB2 gaming state is a lottery table in the RB2 gaming state. In this internal lottery table for RB2 gaming state, the winning number 1 (data pointer 21) is a small winning combination of 1 to 15 and watermelon. In other words, in the RB2 gaming state, all of the small roles 1 to 15 and the watermelon are always won.

<Internal winning combination determination table for small role / replay>
The internal winning combination determination table for a small combination / replay shown in FIG. 17 is a display of an internal winning combination (small combination) that allows display of a combination of symbols related to the payout of medals, and a combination of symbols related to replay operation. The internal winning combination (replay) etc. that allow The contents of the internal winning combination are determined according to the small combination / replay data pointers “0” to “21”. In the data pointer for the small role / replay, the winning numbers shown in FIG. 13 are “1” to “20” excluding “0” corresponding to the loss and “21” corresponding to the overlapping winning combination of the small roles 1 to 15 and the watermelon. It matches. Each data pointer corresponds to three 1-byte data. For example, the data pointer 1 corresponding to the replay 1 has the storage area 1 of “00000001”, the storage area 2 of “00000000”, and the storage area 3 of “00000000”, and the data point 20 corresponding to the watermelon is stored in the storage area 1 Is “00000000”, the storage area 2 is “00000000”, the storage area 3 is “00010000”, and the data point 21 corresponding to the overlapping winning combination of the small roles 1 to 15 and the watermelon is stored in the storage area 1 “11100000”. The area 2 is “11111111” and the storage area 3 is “00011111”.

<Bonus internal winning combination determination table>
The bonus internal winning combination determination table shown in FIG. 18 defines internal winning combinations that allow display of symbol combinations related to the operation of the bonus. The contents of the internal winning combination are determined in correspondence with the bonus data pointers “0” to “2”. The bonus data pointer “0” corresponds to a loss, the bonus data pointer “1” corresponds to BB, and the bonus data pointer “2” corresponds to RB.

<Storage area>
FIG. 19A to FIG. 19F are diagrams showing examples of various storage areas stored in the main RAM 75.

<Internal winning combination storage area>
The internal winning combination storing area shown in FIG. 19A is composed of three storage areas of internal winning combination storing areas 1 to 3. The size of each of the internal winning combination storage areas 1 to 3 is 1 byte. Therefore, the overall size of the internal winning combination storing areas 1 to 3 is 3 bytes. In the internal winning combination storing areas 1 to 3, data determined based on the internal winning combination data (storage area type) defined by the internal winning combination determining table for small combination / replay shown in FIG.

  In the illustrated internal winning combination storing area, for example, bit 0 of the internal winning combination storing area 1 corresponds to replay, bit 1 corresponds to replay 2, bit 2 corresponds to replay 3, and bit 3 corresponds to replay 4. Bit 4 corresponds to the replay 5, bit 5 corresponds to the small combination 1, bit 6 corresponds to the small combination 2, and bit 7 corresponds to the small combination 3. Similarly, each bit of the internal winning combination storage area 2 corresponds to the small combination 4 to small combination 11, and bits 0 to 6 of the internal winning combination storage area 3 are small combination 12 to small combination 15, watermelon, BB, and RB. It corresponds to. In the present embodiment, bit 7 of the internal winning combination storing area 3 is unused.

<Display combination storage area>
The display combination storage area shown in FIG. 19B is composed of three storage areas, display combination storage areas 1 to 3. The size of each of the display combination storage areas 1 to 3 is 1 byte. Therefore, the total size of the display combination storage areas 1 to 3 is 3 bytes. The display combination storage areas 1 to 3 store data determined based on display combination data (storage area type) defined by the symbol combination table shown in FIG.

  In the illustrated display combination storage area, for example, bit 0 of the display combination storage area 1 corresponds to replay, bit 1 corresponds to replay 2, bit 2 corresponds to replay 3, bit 3 corresponds to replay 4, Bit 4 corresponds to replay 5, bit 5 corresponds to small combination 1, bit 6 corresponds to small combination 2, and bit 7 corresponds to small combination 3. Similarly, each bit of the display combination storage area 2 corresponds to the small combination 4 to small combination 11, and each bit of the display combination storage area 3 corresponds to the small combination 12 to small combination 15, watermelon, BB, RB and RT transition symbols. It corresponds.

<Operation stop button storage area>
The operation stop button storage area shown in FIG. 19C is 1 byte in size. Bits 4 to 6 are storage areas indicating stop buttons 17L, 17C, and 17R that can detect a stop operation by the player, that is, effective stop buttons 17L, 17C, and 17R. Bits 0 to 2 are storage areas indicating the stop buttons 17L, 17C, and 17R in which the stop operation corresponding to the valid stop buttons 17L, 17C, and 17R is detected immediately before. In this embodiment, bit 3 and bit 7 are unused and “0” is stored.

  Bit 0 corresponds to the left stop button 17L. When the left stop button 17L is operated by the player, “1” is stored in bit 0. Bit 1 corresponds to the middle stop button 17C. When the middle stop button 17C is operated by the player, “1” is stored in bit 1. Bit 2 corresponds to the right stop button 17R. When the right stop button 17R is operated by the player, “1” is stored in bit 2.

  Bit 4 corresponds to the left stop button 17L. When the left stop button 17L is valid, “1” is stored in bit 4. Bit 5 corresponds to the middle stop button 17C. When the middle stop button 17C is valid, “1” is stored in bit 5. Bit 6 corresponds to the right stop button 17R. When the right stop button 17R is valid, “1” is stored in bit 6. In this embodiment, that the stop button is valid means that a stop operation can be detected. The stop buttons 17L, 17C, and 17R corresponding to the reels rotating at a constant speed and capable of detecting a stop operation are referred to as effective stop buttons.

<Pressing order storage area>
The pressing order storage area shown in FIG. 19D is an area for storing information indicating the pressing order of the three stop buttons 17L, 17C, and 17R. This push-down order storage area has a size of 1 byte, bits “0” to “5” are used, bits “6” and “7” are unused, and “0” is stored. Yes.

  “Bit 0” corresponds to the pressing order “left → middle → right”, and “1” is stored (turned on) in “bit 0” when the pressing order is “left → middle → right”. Similarly, “1” is stored (turned on) in “bit 1” when the pressing order is “left → right → middle”, and “bit 2” when the pressing order is “middle → left → right”. “1” is stored (ON) in “middle → right → left”, “1” is stored (on) in “bit 3”, and “right → left → middle” is “bit”. “1” is stored (ON) in “4”, and “1” is stored (ON) in “bit 5” in the case of “right → middle → left”.

<Carry-over portion storage area>
The carryover combination storage area shown in FIG. 19 (e) is 1 byte in size, bit 0 corresponds to BB, bit 1 corresponds to RB, bits 2 to 7 are unused areas, “0” is stored. As a result of the internal lottery process, “1” is stored in bit 0 of the carryover combination storage area when the internal winning combination BB is determined, and “1” is stored in bit 1 of the carryover combination storage area when the internal winning combination RB is determined. Is stored.

  By storing “1” in bit 0 of the carryover combination storage area, it is possible to determine that the BB has been won. By storing “1” in bit 1 of the carryover combination storage area, it is determined that the RB has been won. Can be determined. The state in which “1” is stored in bit 0 or bit 1 of the carryover combination storage area is held until the combination of symbols corresponding to BB or RB is displayed on the winning determination lines 8a and 8b. In other words, when winning BB or RB, in at least one unit game until the combination of symbols of these bonuses is displayed as a winning combination on the winning determination lines 8a and 8b, bit 0 or The state where “1” is stored in bit 1 is maintained. Maintaining a state in which “1” is stored in bit 0 or bit 1 from the unit game winning the bonus to the unit game winning is referred to as so-called “carryover”. The BB or RB stored in the carryover combination storage area is referred to as a “carryover combination”.

  When a stop operation is performed by the player and each of the reels 3L, 3C, and 3R stops, the internal winning combination storing area is initialized, but the carryover combination storing area is not initialized. In this way, the “carry over” state can be maintained.

<Game state flag storage area>
The game state flag storage area shown in FIG. 19 (f) stores a flag for indicating whether the game state is the bonus game state or the RT game state, and has a size of 1 byte. In this gaming state flag storage area, bits 0 to 5 are used, and bits 6 and 7 are unused, that is, “0” regardless of the gaming state. Bits 0 to 2 relate to the bonus gaming state, and bits 3 to 5 relate to the RT gaming state.

  In the bonus gaming state, bit 0 is set to “1” (on) in the BB gaming state, bit 1 is set to “1” (on) in the RB1 gaming state, and bit 2 is set to “1” in the RB2 gaming state. (On). That is, in the bonus gaming state, the data in the gaming state flag storage area is “00000001” in the BB gaming state, “00000010” in the RB1 gaming state, and “00000100” in the RB2 gaming state.

  In the RT gaming state, bit 3 is set to “1” (ON) in the RT1 gaming state, bit 4 is set to “1” (ON) in the RT2 gaming state, and bit 5 is set to “1” in the RT3 gaming state. (On). That is, in the RT gaming state, the data in the gaming state flag storage area is “00001000” in the RT1 gaming state, “00010000” in the RT2 gaming state, and “00100000” in the RT3 gaming state.

<Pull-in priority table>
The draw priority table shown in FIG. 20A defines the priority, draw priority data corresponding to the priority, and winning operation flag data. In FIG. 20A, for the sake of simplicity, the data of the winning action flag is omitted.

  The priority order defines priority order data that is preferentially drawn in according to the type of the winning action flag. A lower priority value in the pull-in priority table has a higher pull-in priority, and a larger value has a lower pull-in priority.

  In priority order 1 (withdrawal priority order data 00AH), winning action flags for replays 1 to 4 are defined, and in priority order 2 (withdrawing priority order data 008H), a winning action flag for replay 5 is defined. 3 (withdrawal priority data 006H) is defined with the winning action flags for small roles 1 to 3 and watermelon, and the winning action flag for small roles 4 to 15 is defined with priority 4 (withdrawal priority data 004H). In the priority order 5 (withdrawal priority order data 002H), BB and RB winning action flags are defined.

  Note that the data of the winning action flag in the drawing priority table shown in FIG. 20A is data having a size of 1 byte × 3. The data structure of the winning action flag is the same as the structure of the internal winning combination storing area (FIG. 19A). That is, the data 1 to 3 of the winning action flag correspond to the storage areas 1 to 3 of the internal winning combination storage area.

<Retrieve priority data storage area>
The drawing priority data storage area shown in FIG. 20B includes a drawing priority data storage area for the left reel, a drawing priority data storage area for the middle reel, and a drawing priority data storage area for the right reel. . The contents of the middle reel pull-in priority data storage area and the right reel pull-in priority data storage area are the same as those of the left reel pull-in priority data storage area. The data storage area will be described.

  The left reel pull-in priority data storage area can store pull-in priority data for each of the symbol position data (see FIG. 10). For example, for symbol position data 0, the roles defined in the priorities 1 to 5 in FIG. 20A (for example, “BB and RB” from “Replay 1 to 4” to 002H as data 00AH) and data 000H “Stop prohibition” (non-winning) is defined, and from these pull-in priority data, any pull-in priority data is stored in the winning combination and other reels 3C, 3R according to the stop position. Thereby, the left reel 3L is controlled so that the symbol corresponding to the winning combination is stopped or not stopped on the winning determination lines 8a and 8b.

  Similarly, the contents corresponding to the data 00AH to the data 000H are defined for the symbol position data 1 to 20, and the winning combination and other reels 3L, 3C (3R) are stopped from the drawing priority data. Depending on the position, one of the pull-in priority data is stored.

<Reel stop initial setting table>
The reel stop initial setting table shown in FIG. 21 is referred to in order to display a combination of symbols as shown in FIG. 13 or a combination of lost symbols, and a small role / replay data pointer or bonus data pointer (main Is selected from a predetermined reel stop information group based on the game state and the internal winning combination (winning number) defined on the side. Each stop information group determines the correct answer position or incorrect answer position shown in FIG. 13 according to the stop operation position, and determines the type / losing of the winning combination. For example, determination data by pressing order (drawing priority table number and drawing priority table selection table number), change status number, random stop data table number, left reel first stop table change data number, left first stop stop The table number and the stop data table number after the first left stop are defined. These various data indicate various table numbers to be selected in the reel stop control according to the progress of the unit game. These data are data used to determine “slip piece number determination data”, that is, to determine the position at which each of the three reels 3L, 3C, and 3R is stopped according to the progress of the unit game. In this embodiment, a total of 65 reel stop information groups are prepared. For example, for a general game state loss, the general game state, the reel stop information group 0 with a winning number 0 is selected, and the RT3 game state small state is selected. For the combination 5, the reel stop information group 41 with the RT3 gaming state and the winning number 9 is selected, and for the overlap of the small roles 1 to 15 with the RB2 gaming state, the reel stopping information group 35 with the RB2 gaming state and the winning number 1 is selected. The

[Sub-side data tables]
22 to 32 are various data tables stored in the sub ROM 82.

<Setting change mode lottery table>
The setting change mode lottery table shown in FIG. 22 defines the game mode at the time of setting change according to the set value. That is, the setting change mode lottery table is referred to when the setting is changed, and is not referred to except when the setting is changed.

  As the game mode, a low probability and a high probability are provided. These low probability mode (first game mode) and high probability mode (second game mode) affect, for example, the ART lottery probability when a predetermined internal winning combination is won (see FIG. 25). .

  The setting value is a value that defines an expected value of the number of paid-out medals (outgoing rate) with respect to the number of inserted medals. Six stages of six are provided. In the game mode at the time of setting change, the probability that the high probability mode is selected increases as the setting value increases. Further, different non-bonus gaming state internal lottery tables (see FIG. 14) are provided for the respective setting values of the settings 1 to 6, and the non-bonus gaming state corresponding to the setting value as appropriate according to the setting change or the like. An internal lottery table is selected. In the plurality of non-bonus game state internal lottery tables, the higher the set value, the more advantageous to the player, for example, the winning probability of an internal winning combination such as a bonus or watermelon is increased.

<Normal mode lottery table>
The normal mode lottery table shown in FIG. 23 defines the distribution of game modes in the normal gaming state according to the internal winning combination (winning number). That is, the normal mode lottery table is referred to in the normal gaming state and is not referred to in any gaming state other than the normal gaming state.

  In the normal mode lottery table, for example, the low probability mode is always selected for the internal winning combinations corresponding to the winning numbers 1 to 7. In the internal winning combination corresponding to the winning number 20, the low probability mode and the high probability mode are selected with the same probability. That is, in the normal mode lottery table, the probability that the high probability mode is selected increases as the internal winning combination such as a watermelon (winning number 20) called a so-called rare combination. The distribution rate of the game mode shown in the present embodiment is an example and is not limited to this.

<A lottery table with additional ART games>
The ART game number addition lottery table shown in FIG. 24 defines the number of additional games when the ART game number is added during the ART operation according to the game mode. That is, the ART game number addition lottery table is referred to when an ART game number addition occurs during the ART operation, that is, when the internal winning combination corresponding to the winning numbers 8 to 19 is won during the ART operation. As the number of additional games, 10 games, 20 games, 30 games, 50 games, 100 games, and 200 games are set. The number of additional games is not limited to the number of games described above, and an arbitrary number of games can be set.

  In the present embodiment, when in the low probability mode, 10 games are most likely to be selected as the number of additional games, and 200 games are not selected as the number of additional games. On the other hand, when in the high probability mode, 20 games are most likely to be selected as the number of additional games, and 10 games are not selected as the number of additional games. Thus, the probability of selecting a larger value as the number of added games is higher in the high probability mode than in the low probability mode.

<Notice lottery table for BB operation>
In the BB operating notification lottery table shown in FIG. 25, each of the reels 3L, 3C, 3R for winning an internal winning combination when winning one of the small combinations 4 to 15 in a unit game during BB operation. This is a table for lottery of whether or not to notify the 7 symbols (S337 in FIG. 46). The probability of notification varies depending on the game mode when the BB is activated. In the present embodiment, the probability that the presence of notification is selected is higher in the high probability mode than in the low probability mode.

<ART lottery table>
The ART lottery table shown in FIG. 26 is a table that is referred to when performing ART lottery for winning or non-winning the ART based on the game mode and the internal winning combination in the normal gaming state (S394 in FIG. 49). . This ART lottery table is defined such that the probability of winning an ART varies depending on the type of the internal winning combination. Specifically, the internal winning combination corresponding to the winning numbers 8 to 34 has a higher probability of winning the ART than the internal winning combination corresponding to the winning numbers 1 to 7.

  The ART lottery table is defined so that the winning probability of ART varies depending on whether the gaming mode in the normal gaming state is the low probability mode or the high probability mode. Specifically, in the low probability mode, the player does not win the ART with the internal winning combination corresponding to the winning numbers 1 to 7. On the other hand, in the high probability mode, the ART is won with a predetermined probability by the internal winning combination corresponding to the winning numbers 1-7. Further, in the present embodiment, the probability of winning in ART in the high probability mode is higher than that in the low probability mode in the internal winning combination corresponding to the winning numbers 8-34.

[Control processing]
The main CPU 73 of the main control circuit 71 executes various programs according to the flowcharts shown in FIGS.

<Main control of main CPU>
FIG. 27 is a flowchart showing the main control process.

  First, when power is turned on to the pachi-slot machine 1, the main CPU 73 calls and executes a power-on process subroutine shown in FIG. 28, which will be described later (S10). In this power-on process, it is determined whether the backup is normal or the setting has been changed appropriately, and an initialization process is executed according to the determination result.

  Next, the main CPU 73 executes an initialization process at the end of one game (unit game) (S11). In this process, for example, the initialization storage area at the end of one game is designated and initialized. As a result of this initialization processing, the data stored in the internal winning combination storing area or the display winning combination storing area of the main RAM 75 is cleared.

  Next, the main CPU 73 calls and executes a medal acceptance / start check process subroutine shown in FIG. 29 described later (S12). By this medal acceptance / start check process, a process for detecting a medal inserted by the player and a process for detecting a start operation are performed.

  Next, the main CPU 73 extracts a random value and stores it in the random value storage area (S13). Next, the main CPU 73 calls and executes a subroutine of internal lottery processing shown in FIG. 30, which will be described later (S14). The internal lottery process constitutes a process in the internal winning combination determining means.

  Next, the main CPU 73 executes reel stop initial setting processing (S15). By this reel stop initial setting process, a process for determining a reel stop information group (see FIG. 21) based on the internal winning combination is performed. By this reel stop initial setting process, each piece of information (for example, stop table number) related to reel stop control is stored based on the result of the internal lottery process (internal winning combination).

  Next, the main CPU 73 executes start command transmission processing for transmitting start command data from the main control board 31 to the sub control board 41 (S16). The start command includes various kinds of information necessary for producing an internal winning combination.

  Next, the main CPU 73 executes a wait process (S17). This wait process determines whether or not a predetermined time has elapsed since the start of the previous game (start of the previous unit game). If it is determined that the predetermined time has not elapsed, the predetermined time elapses. This is a process to wait until the digestion is complete. The predetermined time in the wait process, that is, the wait time is normally set to 4.1 seconds from the start of the previous unit game, for example.

  Next, the main CPU 73 executes a rotation start process for all the reels 3L, 3C, 3R according to the number of inserted medals (S18). This reel rotation start process constitutes the process in the game start command means. Further, along with the reel rotation start process, “01110000” is stored in the operation stop button storage area shown in FIG.

  The reel rotation start process in S18 described above is executed by an interrupt process (S204 in FIG. 35). This interrupt process is a process executed at a constant cycle (1.1172 milliseconds). By this interruption process, the driving of the stepping motor 38c of each reel 3L, 3C, 3R is controlled, and the rotation of the reels 3L, 3C, 3R is started. Thereafter, the driving of the stepping motor 38c is controlled by this interruption process, and acceleration is performed until the rotation of the reels 3L, 3C, 3R reaches a constant speed. Further, when the rotation of the reels 3L, 3C, and 3R reaches a constant speed thereafter, the driving of the stepping motor 38c is controlled by this interruption process, and the reels 3L, 3C, and 3R are maintained so as to rotate at a constant speed. The

  Next, the main CPU 73 executes reel rotation start command transmission processing for transmitting reel rotation start command data from the main control board 31 to the sub control board 41 (S19). By this reel rotation start command transmission processing, the sub control circuit 72 can recognize the start of reel rotation, and can determine the timing for executing various effects.

  Next, the main CPU 73 executes a pull-in priority storage process (S20). By this drawing priority order storing process, the drawing priority order of all symbols of the rotating reels 3L, 3C, 3R is determined. That is, stop information is stored for each symbol position of each rotating reel based on the internal winning combination. For example, in the case of stop permission, the pull-in priority data is stored based on the priority table. On the other hand, when stop is not permitted (for example, when a winning combination is won), stop prohibition is stored.

  Next, the main CPU 73 calls and executes a subroutine for reel stop control processing shown in FIG. 31 described later (S21). By this process, the stop control of the reels 3L, 3C, 3R is performed.

  Next, the main CPU 73 executes a winning search process (S22). In this winning search process, after all reels are stopped, the symbol combination displayed on the winning determination lines 8a and 8b is checked against the symbol combination table, and the symbol combination displayed for each winning determination line 8a and 8b is determined. This is a process for determining. Specifically, the data stored in the symbol code storage area (not shown) is collated with the data in the symbol combination table shown in FIG. 12, and the result is stored in the display combination storage area (FIG. 19B). Store. Specifically, the data in the symbol code storage area is copied as it is into the display combination storage area. At that time, the payout number is obtained with reference to the symbol combination table. By this winning search process, a process of specifying a combination of symbols displayed on the symbol display means when all reels are stopped is performed.

  Next, the main CPU 73 executes payout of the number of medals according to the displayed symbol combination based on the result of the winning search process (S23). Along with this medal payout process, the drive control of the hopper device 34 and the update of the credit counter are performed based on the payout number counter.

  Next, the main CPU 73 executes display command transmission processing for transmitting display command data from the main control board 31 to the sub control board 41 (S24). The display command includes information such as a display combination.

  Next, the main CPU 73 executes RT control processing shown in FIG. 32 described later (S25). By the RT control process, the gaming state is updated among the general gaming state, the RT1 gaming state, and the RT2 gaming state.

  Next, the main CPU 73 calls and executes a subroutine for bonus end check processing shown in FIG. 33 to be described later (S26). By this bonus end check process, processing in the bonus game end means for ending the operation of the bonus game when the end condition is satisfied is performed.

  Next, the main CPU 73 calls and executes a bonus operation check processing subroutine shown in FIG. 34 (S27). By this bonus operation check processing, processing for operating the bonus game is performed based on the combination of symbols displayed by the reels 3L, 3C, 3R. After executing the process of S27, the process returns to S11 described above.

<Power-on processing>
FIG. 28 is a flowchart showing a subroutine of power-on processing called in S10 of FIG.

  First, the main CPU 73 determines whether the backup is normal (S1011). In this determination process, the main CPU 73 determines whether or not the backup is normal by performing error detection using the checksum value. For example, when the power is turned off, the set value of the pachislot machine 1 (the value at which the payout rate is set to one of six predetermined stages) and the checksum value calculated from the set value are stored in the main RAM 75 as backup data. In the determination process at power-on (S1011), the setting value and the checksum value stored in the main RAM 75 are read out. The checksum calculated from the read setting value is compared with the checksum that was backed up. If the comparison results match, it is determined that the backup is normal.

  When determining that the backup is normal (YES), the main CPU 73 sets the backed up setting value (S1012). As a result, when the backup is normal, the set value before the power is turned off is set.

  After the process of S1012, or when it is determined in S1011 that the backup is not normal (NO), the main CPU 73 determines whether or not the setting change switch is on (S1013). When determining that the setting change switch is not ON (NO), the main CPU 73 determines whether or not the backup is normal (S1019).

  If it is determined in step S1019 that the backup is not normal (NO), the main CPU 73 executes power-on error processing (S1021). In this process, the main CPU 73 displays an error display or the like indicating that the backup is not normal. By the way, the main CPU 73 does not cancel the error state depending on the operation of the stop release switch or the reset switch in the state where the backup is not normal (backup error), and a new setting change has been made. Only when the error state is cleared.

  On the other hand, if it is determined in S1013 that the setting change switch is ON (YES), the main CPU 73 shifts the process to S1014 and executes the initialization process at the time of setting change.

  In the initialization process at the time of changing the setting, for example, the main CPU 75 clears the data stored in the internal winning combination storing area and the display winning combination storing area of the main RAM 73 and also clears the set value.

  After the processing of S1014, the main CPU 73 shifts the processing to S1015, and executes initialization command transmission processing for transmitting initialization command data from the main control board 31 to the sub control board 41. The initialization command data includes, for example, presence / absence of setting value change and setting value information.

  Subsequently, the main CPU 73 shifts the process to S1016 and executes a set value change process. In the setting value changing process, the main CPU 73 selects a setting value from predetermined 1 to 6 in accordance with the operation result of the reset switch, and sets the operation result of the start lever 16 operated subsequently thereto. The set value is confirmed based on this.

  After the set value changing process (S1016), the main CPU 73 shifts the process to S1017 to determine whether or not the setting change switch is in the ON state, and this process (S1017) until a determination result that is not in the ON state is obtained. )repeat. If a determination result (NO) in which the setting change switch is not in the on state is obtained, this means that the operation of the setting change switch has been completed, and the main CPU 73 shifts the processing to S1018 and performs initial processing. An initialization command transmission process for transmitting initialization command data is executed.

  The main CPU 73 ends this subroutine after the processing of S1018. On the other hand, if it is determined in S1019 that the backup is normal (YES), the main CPU 73 shifts the process to S1020 and returns to the state before the power interruption based on the backup data stored in the main RAM 75. .

<Medal reception / start check processing>
FIG. 29 is a flowchart showing a sub-routine for medal acceptance / start check processing called in the processing of S12 of FIG.

  First, the main CPU 73 determines whether or not there is an automatic insertion request (S40). When a replay is won in the previous unit game, medals are automatically inserted in the current unit game. In other words, the determination process in S40 is equivalent to determining whether or not a replay is won in the previous unit game.

  When the main CPU 73 determines in the determination process of S40 that there is an automatic insertion request (YES), the main CPU 73 executes a process of automatically inserting the same number of medals as the medals inserted in the previous unit game (S41). Specifically, the main CPU 73 copies the automatic insertion counter to the insertion number counter and clears the automatic insertion counter.

  Next, the main CPU 73 executes a medal insertion command transmission process for transmitting medal insertion command data from the main control board 31 to the sub-control board 41 (S42), and when this process ends, the process proceeds to S48. Move.

  When the main CPU 73 determines in the determination process of S40 that there is no automatic insertion request (NO), the main CPU 73 executes medal acceptance permission (S43). Specifically, the main CPU 73 drives a solenoid of a selector (not shown) to prompt passage of medals in the selector.

  After executing the process of S43, the main CPU 73 shifts the process to S44, and sets the maximum value of the inserted number according to the gaming state. In the present embodiment, three cards are set in the general gaming state, the RT1 gaming state, the RT2 gaming state, and the RT3 gaming state, and two cards are set in the BB gaming state (RB1 gaming state) and the RB2 gaming state.

  After executing the process of S44, the main CPU 73 shifts the process to S45 to check whether or not there is a medal acceptance permission, and until the determination result that the medal acceptance is permitted is obtained (S45). repeat. If the determination result that the medal acceptance permission is obtained is obtained (YES), it means that the medal can be accepted, and the main CPU 73 moves the process to S46 and checks the inserted medal. .

  The main CPU 73 checks the number of inserted medals when it is determined in the determination process of S45 that there is a medal acceptance permission (YES) (S46). By this processing, the value of the inserted number counter is updated according to the number of checked medals.

  After executing the processing of S46, the main CPU 73 shifts the processing to S47 and executes medal insertion command transmission processing for transmitting medal insertion command data from the main control board 31 to the sub control board 41.

  Next, the main CPU 73 shifts the processing to S48, and determines whether or not the number of inserted medals is the number that can start the game. That is, the main CPU 73 determines whether or not the number of inserted medals is the number that can start the unit game according to the gaming state. In the present embodiment, in the general gaming state, the RT1 gaming state, the RT2 gaming state, and the RT3 gaming state, it is determined whether three medals are inserted, and in the BB gaming state (RB1 gaming state) and the RB2 gaming state. It is determined whether there are two medals inserted.

  When the main CPU 73 determines in S48 that the inserted number of inserted medals is not the number that can start the game (NO), the main CPU 73 returns the process to S45 described above.

  When the main CPU 73 determines that the number of medals inserted in the determination process of S48 is the number that can start the game (YES), it determines whether or not the start switch 57 is on (S49).

  When the main CPU 73 determines that the start switch 57 is not on in the determination processing of S49 (NO), the main CPU 73 returns the processing to S45 described above.

  When the main CPU 73 determines in the determination process of S49 that the start switch 57 is on (YES), the main CPU 73 prohibits medal reception (S50) and ends this subroutine. Specifically, without driving a selector (not shown) solenoid, medals inserted into the insertion slot are urged to be discharged from the medal payout opening 18.

<Internal lottery processing>
FIG. 30 is a flowchart showing a subroutine of an internal lottery process called in the process of S14 of FIG.

  First, the main CPU 73 sets an internal lottery table corresponding to the gaming state (S61). In the present embodiment, when the gaming state is the non-bonus gaming state, the internal lottery table of FIG. 14 is displayed regardless of whether the gaming state is the general gaming state, the RT1 gaming state, the RT2 gaming state, or the RT3 gaming state. refer. On the other hand, when the gaming state is the bonus gaming state, the RB1 gaming state internal lottery table shown in FIG. 15 or the RB2 gaming state internal lottery table shown in FIG. 16 is set.

  Next, the main CPU 73 obtains a random value stored in the random value storage area (S62).

  Next, the main CPU 73 obtains a lottery value corresponding to the winning number using the predetermined area of the internal lottery table set in the process of S61, and subtracts the lottery value from the random number value (S63). That is, the main CPU 73 collates the internal winning combination.

  Next, the main CPU 73 determines whether or not the subtraction result obtained in S64 is smaller than 0 (S43).

  When determining that the subtraction result is not smaller than 0 (NO), that is, when determining that so-called borrowing is not performed, the main CPU 73 updates the random number value and the winning number (S65). ).

  Next, the main CPU 73 determines whether or not all winning numbers in the used internal lottery table have been checked (S66).

  Next, when the main CPU 73 determines in the determination process of S66 that all winning numbers have not been checked (NO), the main CPU 73 returns the process to S63 described above.

  Next, when the main CPU 73 determines in the determination process of S66 that all winning numbers have been checked (YES), it sets 0 as the value of the data pointer (S67). That is, the main CPU 73 determines that the display combination is lost as a result of the internal lottery.

  Next, when the main CPU 73 determines that the subtraction result is smaller than 0 in the determination process of S64 described above (YES), that is, when it is determined that so-called borrowing has been performed, the main lottery table used is determined. The value of the data pointer for small role / replay and the value of the data pointer for bonus are acquired by referring to (S68).

  Next, after executing the processing of S67 or S68 described above, the main CPU 73 refers to the small winning combination / replay internal winning combination determination table shown in FIG. 17 and based on the value of the small winning combination / replay data pointer. An internal winning combination is acquired (S69). The processing of S69 is performed by referring to the small winning combination / replay internal winning combination determination table shown in FIG. 17 using the value of the small winning combination / replay data pointer determined in the processing of S67 or S68 described above. A process of determining a 3-byte data value indicating an internal winning combination corresponding to the value of the replay data pointer.

  Next, the main CPU 73 stores the acquired internal winning combination in the corresponding internal winning combination storing area (FIG. 19A) (S70). The process of S70 is a process of storing the 3-byte data value indicating the internal winning combination determined in the process of S69 in the internal winning combination storing area (storage areas 1 to 3) shown in FIG.

  Next, the main CPU 73 determines whether or not the value of the carryover combination storage area (FIG. 19E) is 0 (S71). This determination process is a process for determining whether or not the data value stored in the carryover combination storage area shown in FIG. That is, the determination process of S71 is a process of determining whether neither BB nor RB has been carried over.

  Next, when the main CPU 73 determines in S71 that the value of the carryover combination storage area is 0 (YES), the main CPU 73 refers to the bonus internal winning combination determination table shown in FIG. An internal winning combination is acquired based on the value of (S72). The processing of S72 corresponds to the value of the bonus data pointer by referring to the bonus internal winning combination determination table shown in FIG. 18 using the value of the bonus data pointer determined in the processing of S67 or S68 described above. This is a process of determining a 3-byte data value indicating the internal winning combination.

  Next, the main CPU 73 stores the acquired internal winning combination in the carryover combination storage area (FIG. 19E) (S73). The process of S73 is a process of setting the value of the bit corresponding to the acquired internal winning combination among the bits 0 and 1 of the carryover storage area shown in FIG.

  Next, the main CPU 73 determines whether or not the value of the carryover combination storage area (FIG. 19 (e)) is 0 (S74). This determination process is a process for determining whether or not the data value stored in the carryover combination storage area shown in FIG. That is, the determination process of S74 is a process of determining whether any of BB or RB has been carried over.

  Next, when the main CPU 73 does not determine that the value of the carryover combination storage area is 0 in the determination process of S74 (NO), the main CPU 73 updates the gaming state defined on the main side to the RT3 gaming state (S75). . The process of S75 is a process of shifting the gaming state to RT3 when the bonus flag is carried over regardless of whether BB or RB is used.

  When the main CPU 73 does not determine that the value of the carryover combination storage area is 0 in the determination process of S71 described above (NO), the main CPU 73 determines that the value of the carryover combination storage area is 0 in the determination process of S74 described above. When the determination is made (YES) or when the process of S75 is executed, the internal winning combination storing area is updated based on the internal winning combination stored in the carryover combination storing area (S76). The process of S76 is based on the internal winning combination storing area shown in FIG. 19A based on the type of internal winning combination stored in the carryover combination storing area shown in FIG. It is a process to update. When the process of S76 is executed, this subroutine is terminated.

<Reel stop control process>
FIG. 31 is a flowchart showing a subroutine of the reel stop control process called up in the process of S21 of FIG.

  First, the main CPU 73 determines whether or not a valid stop button has been pressed (S90). This process is a process for determining whether or not a signal is output from a stop switch provided on the stop switch board 58. When determining that the effective stop button is not pressed (NO), the main CPU 73 repeats the process of S90.

  When the main CPU 73 determines in S90 that the valid stop buttons 17L, 17C, and 17R have been pressed (YES), the main CPU 73 changes to FIG. 19C according to the pressed stop buttons 17L, 17C, and 17R. The operation stop button storage area shown in FIG. 19 and the pressing order storage area shown in FIG. 19D are updated (S91).

  The main CPU 73 stores the types of operation stop buttons corresponding to the first stop operation, the second stop operation, and the third stop operation in the pressing order storage area shown in FIG. By referencing, it is possible to determine the pressing order of the stop buttons 17L, 17C, and 17R.

  Next, the main CPU 73 decrements the stop button non-operating counter by 1 (S92).

  Next, the main CPU 73 determines a search target reel from the operation stop button (S93).

  Next, the main CPU 73 stores the stop start position based on the symbol counter (S94). The stop start position is a symbol position corresponding to the symbol counter of the corresponding reel when a stop operation is detected by the stop switch.

  Next, the main CPU 73 executes a sliding piece number determination process (S95). In this sliding piece number determination process, the number of sliding pieces defined at the stop start position is acquired based on the reel stop information group selected based on the internal winning combination from the reel stop initial setting table shown in FIG.

  Next, the main CPU 73 executes a sliding piece number correction process (S96). In this sliding piece number correction processing, it is determined whether or not the drawing priority order data of the acquired number of sliding pieces is the highest within the range of the maximum number of sliding pieces (4 pieces), and higher drawing priority data is obtained. In some cases, the number of sliding pieces is corrected so as to stop at that position.

  Next, the main CPU 73 executes reel stop command transmission processing for transmitting reel stop command data from the main control board 31 to the sub control board 41 (S97). This reel stop command includes information such as the type of reel to be stopped, the stop start position, and the number of sliding pieces (or the planned stop position).

  Next, the main CPU 73 determines and stores a scheduled stop position based on the stop start position and the number of sliding pieces (S98). The scheduled stop position is a symbol position obtained by adding any of predetermined numerical values “0” to “4” defined as the number of sliding pieces to the stop start position, and the symbol position where the reel rotation stops. It is.

  Next, the main CPU 73 performs a control change process (S99). In this control change process, the reel stop information group is updated when a specific stop position is reached. For example, if a small winning combination 4 and BB are overlapped, if the stop operation is performed at the correct answer position of the winning combination of the small combination 4, no control change process is required, but the small role 4 stops at the incorrect winning position of the non winning prize When the operation is performed, the BB reel stop information group and the like are acquired again.

  Next, the main CPU 73 determines whether or not the stop button non-operation counter is 0 (S100).

  When the main CPU 73 determines in the determination process of S100 that the stop button non-operation counter is not 0 (NO), the main CPU 73 executes the pull-in priority storage process (S101), and returns the process to S90.

  When the main CPU 73 determines that the stop button non-operating counter is 0 (YES) in the determination processing of S100, the main CPU 73 immediately ends this subroutine.

<RT control processing>
FIG. 32 is a flowchart showing a subroutine of RT control processing called in the processing of S25 of FIG.

  First, the main CPU 73 determines whether or not BB or RB is in operation (S120). In the process of S120, it is determined whether the BB gaming state or the RB gaming state that does not require RT control is in operation.

  When determining that the BB or the RB is not operating (NO) in the determination process of S120, the main CPU 73 determines whether or not the main game state is the RT3 game state (S121). In the process of S121, it is determined whether the RT3 gaming state has no transition destination other than the bonus gaming state.

  When the main CPU 73 does not determine that the game is in the RT3 gaming state in the determination process of S121 (NO), the main CPU 73 determines whether or not the replay 5 is displayed (S122). In this determination process, it is determined whether or not the replay 5 that is a demoted replay from the RT1 gaming state (see FIG. 9) is displayed. Here, Replay 5 wins in duplicate with Replay 2, Replay 3 or Replay 4 (3 choice replay) in the RT1 gaming state (see FIG. 14), and Replay 2, Replay 3 or Replay 4 is displayed. It is displayed when it is not made (when the three-choice replay is incorrect).

  When it is determined in the determination process of S122 that the replay 5 is displayed (YES), the main CPU 73 updates the gaming state to the general gaming state (S123). That is, since the replay 5 is displayed only in the RT1 gaming state (see FIG. 14) and is a demoted replay from RT1 to the general gaming state, the gaming state is demoted to the general gaming state (see FIG. 9).

  When the main CPU 73 does not determine that the replay 5 is displayed in the determination process of S122 (NO), the main CPU 73 determines whether or not the RT transition symbol is displayed (S124). Here, since the RT transition symbol (“Replay-Bell-Bell”) is a symbol for transitioning to the RT1 gaming state (see FIG. 9), whether the gaming state is transitioned to the RT1 gaming state in the determination process of S124. To be judged.

  When the main CPU 73 determines in the determination process of S124 that the RT transition symbol is displayed (YES), the main CPU 73 updates the gaming state to the RT1 gaming state (S125). That is, since the RT transition symbol is for transitioning the gaming state from the general gaming state to the RT1 gaming state or from the RT2 gaming state to the RT1 gaming state (see FIG. 9), The state is updated to the RT1 gaming state.

  When it is not determined that the RT transition symbol is displayed in the determination process of S124 (NO), the main CPU 73 determines whether or not replays 2 to 4 (three-choice replay) are displayed (S126). Here, replays 2 to 4 (“red 7 / blue 7 / yellow 7-replay-replay”) are won only in the RT1 gaming state (see FIG. 11), and the RT1 gaming state changes to the RT2 gaming state. Since it is a promotion replay (see FIG. 9), it is determined in the determination process of S126 whether or not to shift the gaming state to the RT2 gaming state.

  When the main CPU 73 determines that replays 2 to 4 are displayed in the determination process of S126 (YES), the main CPU 73 updates the gaming state to the RT2 gaming state (S127). That is, since the replays 2 to 4 are for changing the gaming state from the RT1 gaming state to the RT2 gaming state (see FIG. 9), the gaming state is updated to the RT2 gaming state as the replays 2 to 4 are displayed. The

  When the main CPU 73 determines that BB or RB is in operation in the determination process of S120 (YES), or the determination of the RT3 gaming state in the determination process of S121 (YES), the process of S123 ends. When the process of S125 is completed, when it is not determined that the replays 2 to 4 are displayed in the determination process of S126, this subroutine is terminated.

<Bonus end check process>
FIG. 33 is a flowchart showing a bonus end check process subroutine called in the process of S26 of FIG.

  First, the main CPU 73 determines whether or not it is in the RB gaming state (S130). As a result, if the main CPU 73 does not determine that it is in the RB gaming state (NO), this subroutine is terminated. On the other hand, if the main CPU 73 determines that it is in the RB gaming state (YES), it subtracts 1 from the winning number counter and the possible game number counter (S131).

  Next, the main CPU 73 determines whether or not the winning number counter or the possible game number counter is “0” (S132). As a result, if the main CPU 73 does not determine that the winning counter or the possible game counter is “0” (NO), the main CPU 73 shifts the process to S134. On the other hand, when the main CPU 73 determines that the winning number counter or the possible game number counter is “0”, the main CPU 73 performs RB end processing for turning off the RB gaming state flag (S133), and shifts the processing to S134.

  Subsequently, the main CPU 73 determines whether or not it is in the BB gaming state (S134). As a result, if the main CPU 73 does not determine that it is in the BB gaming state (NO), it moves the process to S138. On the other hand, if the main CPU 73 determines that it is in the BB gaming state (YES), it updates the bonus end number counter (S135) and determines whether or not the value of the bonus end number counter is smaller than “0”. (S136).

  In S136, if the main CPU 73 does not determine that the value of the bonus end number counter is smaller than “0” (NO), the main CPU 73 ends the present subroutine. On the other hand, when determining that the value of the bonus end number counter is smaller than “0”, the main CPU 73 performs a BB end process for turning off the BB gaming state flag and turning off the RB gaming state flag (S137). .

  Subsequently, the main CPU 73 executes a bonus end command transmission process for transmitting bonus end command data from the main control board 31 to the sub control board 41 (S138). When the process of S138 is finished, this subroutine is finished.

<Bonus activation check process>
FIG. 34 is a flowchart showing a subroutine of bonus operation check processing called in the processing of S27 of FIG.

  First, the main CPU 73 determines whether the BB is operating (S140). As a result, when determining that the BB is operating (YES), the main CPU 73 determines whether the RB1 is operating (S141). If the main CPU 73 determines that the RB1 is in operation (YES), this subroutine is terminated. On the other hand, when determining that the RB1 is not operating (NO), the main CPU 73 performs an RB1 operating process (S142). In this process, the RB1 gaming state flag is turned on, “8” is set in the winning number counter, and “12” is set in the possible game number counter. When the process of S142 is finished, this subroutine is finished.

  In step S140, when the main CPU 73 does not determine that the BB is operating (NO), the main CPU 73 determines whether or not a symbol combination corresponding to RB is displayed (S143). As a result, if the main CPU 73 determines that the symbol combination corresponding to the RB is displayed (YES), the main CPU 73 performs the RB2 operation process (S144). In this process, the RB2 gaming state flag is turned on, and “8” is set in the winning number counter and the possible game number counter. Also, the RT gaming state flag is turned off. If this process ends, the process moves to S147.

  On the other hand, if the main CPU 73 does not determine in step S143 that the symbol combination corresponding to the display combination “RB” is displayed (NO), whether or not the symbol combination corresponding to the display combination “BB” is displayed. Is determined (S145). As a result, when the main CPU 73 determines that the symbol combination corresponding to the display combination “BB” is displayed (YES), the main CPU 73 performs the BB operation processing (S146). In this process, the BB gaming state flag is turned on, and a predetermined number (for example, 390) is set in the bonus end number counter. At this time, the RB1 operation process of S142 described above is also performed. Also, the RT gaming state flag is turned off.

  Next, the main CPU 73 clears the value of the carryover combination storage area (S147), and executes a bonus start command transmission process for transmitting bonus start command data from the main control board 31 to the sub control board 41 (S148). The main CPU 73 ends this subroutine after the processing of S148.

  If the main CPU 73 does not determine in S145 that the symbol combination corresponding to BB is displayed (NO), the main CPU 73 determines whether the symbol combination corresponding to replays 1 to 5 is displayed (S149). As a result, if the main CPU 73 does not determine that the symbol combinations corresponding to the replays 1 to 5 are displayed (NO), the main CPU 73 ends the on-subroutine. On the other hand, when determining that the symbol combinations corresponding to replays 1 to 5 are displayed (YES), the main CPU 73 makes an automatic insertion request for copying the value of the insertion number counter to the automatic insertion number counter (S150). This subroutine is finished.

<Interrupt processing under main CPU control>
FIG. 35 is a flowchart showing a subroutine for interrupt processing under the control of the main CPU 73. This process is called and executed every 1.1172 milliseconds.

  First, the main CPU 73 saves the register (S200). Subsequently, the main CPU 73 performs an input port check process (S201). In this process, the main CPU 73 confirms the presence / absence of a signal transmitted to the microcomputer 72. For example, the main CPU 73 stores the on edge and the off edge of the start switch 57, the stop switch, and the like for each interrupt process. The main CPU 73 stores an input state command including information on the on-edge and off-edge of various switches in a communication data storage area of the main RAM 75. The stored input state command is transmitted to the sub control circuit 81 in a command data transmission process of an interrupt process described later. Accordingly, various effects can be executed using the operation means such as the start lever 16 and the stop buttons 17L, 17C, and 17R.

  Subsequently, the main CPU 73 performs a timer update process (S202). Next, the main CPU 73 performs command data transmission processing (S203). In this process, command data is transmitted to the sub control circuit 81 of the sub control board 41. Subsequently, the main CPU 73 performs a process of controlling the rotation of the reels 3L, 3C, 3R (S204). More specifically, the main CPU 73 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 73 performs a lamp / 7SEG driving process (S205). For example, the main CPU 73 displays the number of credited medals, the number of payouts, etc. on various display units. Subsequently, the main CPU 73 restores the register (S206), and terminates the interrupt processing that occurs periodically.

[Sub control processing]
The sub CPU 82 of the sub control circuit 72 executes various programs according to the flowcharts shown in FIGS.

<Processing at power-on>
FIG. 36 is a flowchart showing the operation of the sub-control circuit 72 for processing at power-on.

  First, the sub CPU 82 executes an initialization process (S230). In this process, the sub CPU 82 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.

  Next, the sub CPU 82 activates the lamp control task shown in FIG. 37 (S231). The lamp control task waits for the sub CPU 82 to receive a timer interrupt event message transmitted to the sub CPU 82 every 2 milliseconds, and in response to receiving the timer interrupt event message, It is a process which performs the process which controls a lighting state.

  Next, the sub CPU 82 activates the sound control task shown in FIG. 38 (S232). The sound control task is a process in which the sub CPU 82 executes a process of controlling a sound output state from the speakers 48L, 48R, 49L, and 49R.

FIG. 37 is a flowchart showing a lamp control task.

  First, the sub CPU 82 executes a timer interrupt initialization process (S240).

  Next, the sub CPU 82 executes lamp related data initialization processing (S241).

  Next, the sub CPU 82 waits for a timer interrupt (S242). In this process, until the sub CPU 82 receives a timer interrupt event message every 2 milliseconds, the sub CPU 82 executes a task group different from the timer interrupt synchronization. As a task group different from timer interrupt synchronization, for example, a main board communication task which is a task group for command reception interrupt synchronization can be cited. Further, a task group (not shown) for power supply interrupt synchronization and a task group (not shown) for door monitoring unit communication synchronization can be mentioned.

  Next, the sub CPU 82 executes the sound control task shown in FIG. 38 (S243). In this process, the task in the next priority of the timer interrupt synchronization task group which is the same group as the lamp control task is executed. In the embodiment, the priority order of the task group for timer interrupt synchronization is basically the order of the lamp control task and the sound control task. Therefore, in S243, the sound control task at the next priority of the lamp control task is executed. In S243, the processing of S252 and S253 is performed in the sound control task shown in FIG.

  Next, the sub CPU 82 executes lamp data analysis processing (S244).

  Next, the sub CPU 82 executes lamp lighting control processing (S245), and returns the processing to S242.

<Sound control task>
FIG. 38 is a flowchart showing a sound control task.

  Next, the sub CPU 82 executes activation of the main board communication task (S261).

  Next, the sub CPU 82 activates the animation task (S262) and aborts the process.

<Main task>
FIG. 40 is a flowchart showing the main task.

  First, the sub CPU 82 executes a VSYNC interrupt initialization process (S270).

  Next, the sub CPU 82 waits for VSYNC interruption (S271).

  Next, the sub CPU 82 executes a drawing process (S272), and returns the process to S271.

<Main board communication task>
FIG. 41 is a flowchart showing the main board communication task.

  First, the sub CPU 82 executes initialization of the communication message queue (S1081).

  Next, the sub CPU 82 executes a reception command check (S1082). Next, the sub CPU 82 determines whether or not a command different from the previous one has been received (S1083).

  If the sub CPU 82 determines in S1083 that the command different from the previous command has not been received (NO), the sub CPU 82 shifts the process to S1082. On the other hand, if it is determined that a command different from the previous command has been received (YES), it is determined that the received command is a legitimate command, the process proceeds to S1084, and game information is created from the received command. ,Store.

  Then, the sub CPU 82 calls and executes a command analysis processing subroutine shown in FIG. 42 (S1085), and shifts the processing to the above-described S1082.

<Command analysis processing>

  Next, the sub CPU 82 executes lamp data determination processing (S291).

  Next, the sub CPU 82 executes sound data determination processing (S292).

  Next, the sub CPU 82 registers each determined data (S293), and ends this subroutine.

<Anime task>
FIG. 43 is a flowchart showing an animation task.

  First, the sub CPU 82 checks a change from the previous game information (step S300). Specifically, the sub CPU 82 determines whether or not the current game information updated by the interrupt process (FIG. 35) is different from the game information registered in the sub RAM 83 in the previous interrupt process. To check.

  Subsequently, the sub CPU 82 executes object control processing (step S301). Specifically, in the above-described step S300, when a check result indicating that the gaming state has changed is obtained, the sub CPU 82 controls the image according to the change in the gaming state.

  Subsequently, the sub CPU 82 executes an animation task management process (step S302), and moves the process to the above-described S300. Specifically, when the power is turned on when the setting change switch provided in the cabinet 2a of the pachislot machine 1 is on, an initialization command indicating that is sent from the main control circuit 71 to the sub control circuit 81. The sub CPU 82 issues a hall menu task execution request corresponding to the initialization command in the animation task management process (step S302). Thus, when the initialization command is received, the hall menu is displayed on the liquid crystal display device 10.

<Production content determination process>
FIG. 44 is a flowchart showing effect content determination processing.

  First, the sub CPU 82 determines whether or not the initialization command is received (S310). For example, the main CPU 73 transmits presence / absence of setting value change and information on setting values as an initialization command. The sub CPU 82 receives these as initialization commands in the process of S311.

  When the sub CPU 82 determines that the initialization command is received in the determination process of S310 (YES), the sub CPU 82 calls and executes the initialization command reception process shown in FIG. 45 (S311), and ends this subroutine.

  When the sub CPU 82 determines that the initialization command is not received in the determination process of S310 (NO), the sub CPU 82 determines whether or not the medal insertion command is received (S312).

  When the sub CPU 82 determines that the medal insertion command is received in the determination process of S312 (YES), the sub CPU 82 executes the medal insertion command reception process (S313) and ends this subroutine. For example, the main CPU 73 transmits the presence / absence of a medal and the value of the inserted number counter / credit counter as a medal insertion command. In step S313, the sub CPU 82 receives these as medal insertion commands.

  When the sub CPU 82 determines in S312 that the medal insertion command is not received (NO), the sub CPU 82 determines whether it is a start command reception (S314).

  When the sub CPU 82 determines in the determination process of S314 that the start command is received (YES), the sub CPU 82 calls and executes the start command reception process shown in FIG. 46 (S315), and ends this subroutine. For example, the main CPU 73 transmits a game state flag type, a bonus end number counter value, and an internal winning combination type as a start command. In step S315, the sub CPU 82 receives these as start commands.

  When determining that the start command is not received (NO) in the determination process of S314 (NO), the sub CPU 82 determines whether or not the reel rotation start command is received (S316).

  When the sub CPU 82 determines in the determination process of S316 that the reel rotation start command is received (YES), the sub CPU 82 executes a reel rotation start command reception process (S317), and ends this subroutine. For example, the main CPU 73 transmits that the rotation of the reel has been started as a reel rotation start command. In step S317, the sub CPU 82 receives this as a reel rotation start command.

  When the sub CPU 82 determines that the reel rotation start command is not received in the determination process of S316 (NO), the sub CPU 82 determines whether or not it is a reel stop command reception (S318).

  When the sub CPU 82 determines in S318 that the reel stop command is received (YES), the sub CPU 82 executes the reel stop command reception processing (S319), and ends this subroutine. For example, the main CPU 73 transmits the type of stop reel, the stop start position, and the number of sliding frames (or the planned stop position) as a reel stop command. The sub CPU 82 receives these as reel stop commands in the process of S319.

  When determining that the reel stop command is not received (NO) in the determination processing of S318, the sub CPU 82 determines whether or not the display command is received (S320).

  When the sub CPU 82 determines in the determination process of S320 that the display command is received (YES), the sub CPU 82 executes the display command reception process shown in FIG. 50 (S321), and ends this subroutine. For example, the main CPU 73 transmits a display combination or the like as a display command. The sub CPU 82 receives these as display commands in the process of S321.

  When the sub CPU 82 determines that the display command is not received in the determination process of S320 (NO), the sub CPU 82 determines whether or not it is a bonus start command reception (S322).

  When the sub CPU 82 determines in S322 that the bonus start command is received (YES), the sub CPU 82 executes the bonus start command reception processing (S323), and ends this subroutine. For example, the main CPU 73 transmits a bonus start command as a bonus start command. In step S323, the sub CPU 82 receives this as a bonus start command.

  When the sub CPU 82 determines that the bonus start command is not received in the determination process of S322 (NO), the sub CPU 82 determines whether the bonus end command is received (S324).

  When the sub CPU 82 determines in the determination process of S324 that the bonus end command is received (YES), the sub CPU 82 executes the bonus end command reception process (S325), and ends the present subroutine. For example, the main CPU 73 transmits a bonus end command as a bonus end command. In step S325, the sub CPU 82 receives this as a bonus end command.

  When the sub CPU 82 determines that the bonus end command is not received in the determination process of S324 (NO), the sub CPU 82 determines whether the input state command is received (S326).

  When the sub CPU 82 determines in the determination process of S326 that the input state command is received (YES), the sub CPU 82 executes the input state command reception process (S327), and ends this subroutine. For example, the main CPU 73 transmits, as an input state command, whether each operation unit is in an on-edge state or an off-edge state. The sub CPU 82 receives these as input state commands in the process of S327.

  If the sub CPU 82 determines in step S326 that the input state command is not received (NO), the sub CPU 82 ends the present subroutine.

<Initialization command reception processing>
FIG. 45 is a flowchart showing processing upon reception of an initialization command.

  First, the sub CPU 82 determines whether or not there is a setting change (S330). The sub CPU 82 can determine whether or not there is a setting change based on information on whether or not the setting change switch transmitted from the main CPU 73 is ON. If the sub CPU 82 determines that there is no setting change (NO), the sub CPU 82 ends the present subroutine.

  In S330, when the sub CPU 82 determines that there is a setting change (YES), the sub CPU 82 determines whether or not the setting change mode hold flag is on (S331). If the sub CPU 82 determines that the setting change mode hold flag is on (YES), the sub CPU 82 ends the present subroutine.

  In S331, when the sub CPU 82 determines that the setting change holding flag is OFF (NO), the sub CPU 82 refers to the setting change mode lottery table (FIG. 22) and executes the mode transition lottery processing (S332).

  Next, the sub CPU 82 determines whether or not the high probability mode is won in the mode transition lottery process of S332 (S333). If the sub CPU 82 does not determine that the high probability mode has been won (NO), the sub CPU 82 ends the present subroutine.

  In S333, when determining that the high probability mode has been won (YES), the sub CPU 82 turns on the setting change mode holding flag, sets 500 as a value to be set in the mode management counter (S334), This subroutine ends. Thereby, after the setting change, the high probability mode is maintained for 500 games. Specifically, after the setting change mode hold flag is turned on in S335 and the mode management counter is set to 500, if the next loop initialization command reception process is executed, a YES determination is made in S331. The mode lottery in S332 is not executed. For this reason, once the high probability mode is won at the time of setting change, the low probability mode is not selected even if the manager of the game hall changes the setting again. Further, since the mode management counter is also set to 500, the mode is not shifted to the low probability mode unless the number of games reaches 500 games. Therefore, it is possible to prevent the setting change from being repeatedly executed until the low probability mode is selected by the game hall manager or the like. In other words, game mode selection at the time of setting change is not entrusted to a game hall manager or the like, and the fairness of the game is ensured.

<Processing when receiving a start command>
FIG. 46 is a flowchart showing processing upon reception of a start command.

  First, the sub CPU 82 determines whether or not the RB is operating (S340). If the sub CPU 82 determines that the RB is operating (YES), it determines the RB operating effect data (S341), and ends this subroutine.

  In S340, if the sub CPU 82 does not determine that the RB is operating (NO), it determines whether or not the BB is operating (S342). If the sub CPU 82 does not determine that the BB is in operation (NO), the sub CPU 82 can determine that it is in the non-bonus game state, and thus the process proceeds to S352.

  In S342, when the sub CPU 82 determines that the BB operation is being performed (YES), the sub CPU 82 determines whether or not the winning number is 0, that is, whether it is a loss (S343).

  In S343, when determining that the winning number is 0 (lost) (YES), the sub CPU 82 adds 5 to the ART set number counter (S344). In other words, the sub CPU 82 adds 5 sets of ART games when the player loses a unit game during BB operation.

  Next, the sub CPU 82 determines ART winning effect data (S345), and ends this subroutine. With this ART winning effect data, it is possible to notify or indicate to the player that the ART lottery has been won.

  On the other hand, in S243, when the sub CPU 82 does not determine that the winning number is 0 (lost) (NO), the sub CPU 82 determines whether the winning number is 2 to 13 (S346). Here, the winning numbers 2 to 13 correspond to the single winnings of the small roles 4 to 15, and these small roles 4 to 15 have 7 symbols on the left reel 3L, the middle reel 3C, and the right reel 3R. Is a 15-piece combination (when the number of inserted medals is 2).

  If the sub CPU 82 determines that the winning number is 2 to 13 (small roles 4 to 15) (YES), the sub CPU 82 refers to the BB operating notification lottery table shown in FIG. 25 and based on the current game mode. The presence / absence of notification is determined (S347). In this process, notification means navigating the seven symbols of the reels 3L, 3C, and 3R for winning the small combinations 4 to 15 that are internal winning combinations. As a result, the player can win the small winning combinations 4 to 15 by winning. Here, when the small roles 4 to 15 are won in the unit game in which the BB is operating, one set of ART sets is added. Therefore, when the notification lottery is won, one set of ART games can be acquired by stopping the 7 symbols that have been navigated to the reels 3L, 3C, and 3R.

  Next, the sub CPU 82 determines whether or not to perform notification, that is, whether or not the notification lottery has been won in S347 (S348). If the sub CPU 82 determines that notification is to be made (YES), it determines BB operating notification effect data according to the winning number (S349). That is, the data regarding the combination of 7 symbols of the display combination corresponding to the winning number is determined. When this process is finished, this subroutine is finished.

  On the other hand, if the sub CPU 82 determines that the notification is not performed in S348 (NO), the sub CPU 82 determines the chance effect data for BB operation (S350), and ends the present subroutine. Here, the BB operation chance effect is, for example, performing 7 symbols of navigation on each reel 3L, 3C, 3R with respect to one or two reels 3L, 3C, 3R, This is an effect that informs that there is a possibility that the number of ART sets may be added.

  In S346, if the sub CPU 82 does not determine that the winning number is 2 to 13 (small role 4 to 15) (NO), the BB operating effect data is determined (S351), and this subroutine is terminated.

  In S342, if the sub CPU 82 does not determine that the BB is in operation (NO), it can be determined that the player is in the non-bonus gaming state, so the mode transition lottery process shown in FIG. 47 described later is executed (S352).

  Next, the sub CPU 82 determines whether or not the ART flag is on (S353). If the sub CPU 82 determines that the ART flag is on (YES), it executes the ART processing shown in FIG. 48 (S354) and ends this subroutine. On the other hand, if the sub CPU 82 does not determine that the ART flag is on (NO), the sub CPU 82 executes the normal process shown in FIG. 49 (S355) and ends the present subroutine.

<Mode transfer lottery processing>
FIG. 47 is a flowchart showing the mode transition lottery process.

  First, the sub CPU 82 determines whether or not the special stock return mode retention flag is ON (S360). If the sub CPU 82 does not determine that the special stock return mode hold flag is on (NO), it moves the process to S364.

  In S360, when the sub CPU 82 determines that the special stock return mode hold flag is ON (YES), the sub CPU 82 decrements the mode management counter by 1 (S361). The mode management counter is a counter for the period during which the game mode stays in the low probability mode or the high probability mode, that is, the number of games. Note that only the number of games in the high probability mode may be set as a counter value in the mode management counter. Therefore, by the process of S361, the value of the mode management counter equal to the value of the ART game number counter stored in the special stock storage process shown in S384 of FIG.

  Next, the sub CPU 82 determines whether or not the value of the mode management counter is 1 or more (S362). If the sub CPU 82 determines that the value of the mode management counter is 1 or more (YES), it ends this subroutine.

  In S362, when determining that the value of the mode management counter is not 1 or more, that is, 0 (NO), the sub CPU 82 turns off the special stock return mode hold flag (S363), and ends this subroutine. .

  In S360, if the sub CPU 82 does not determine that the special stock return mode hold flag is ON (NO), the sub CPU 82 determines whether the setting change mode hold flag is ON (S364). If the sub CPU 82 does not determine that the setting change mode hold flag is ON (NO), it moves the process to S368.

  In S364, when the sub CPU 82 determines that the setting change mode hold flag is ON (YES), the sub CPU 82 decrements the mode management counter by 1 (S365). Therefore, in the process of S365, the high probability mode is won by the setting change mode transition lottery shown in FIG. 45, and 1 is subtracted from the value set in the mode management counter.

  Next, the sub CPU 82 determines whether the value of the mode management counter is 1 or more (S366). If the sub CPU 82 determines that the value of the mode management counter is 1 or more (YES), it ends this subroutine.

  In S366, when determining that the value of the mode management counter is not 1, that is, 0 (NO), the sub CPU 82 turns off the setting change mode hold flag (S367), and ends this subroutine.

  In S364, if the sub CPU 82 does not determine that the setting change mode retention flag is on (NO), it determines whether the normal mode retention flag is on (S368). If the sub CPU 82 does not determine that the normal mode hold flag is on (NO), it moves the process to S372.

  In S364, if the sub CPU 82 determines that the normal mode hold flag is on (YES), the sub CPU 82 decrements the mode management counter by 1 (S369). Therefore, by the process of S364, the high probability mode is won by the normal mode transition lottery process of S372 described later, and 1 is subtracted from the value set in the mode management counter.

  Next, the sub CPU 82 determines whether or not the value of the mode management counter is 1 or more (S370). If the sub CPU 82 determines that the value of the mode management counter is 1 or more (YES), it ends this subroutine.

  In S370, when determining that the value of the mode management counter is not 1, that is, 0 (NO), the sub CPU 82 turns off the normal mode holding flag (S371) and ends this subroutine.

  In S368, if the sub CPU 82 does not determine that the normal mode holding flag is ON (NO), the sub CPU 82 refers to the normal mode lottery table (FIG. 23) and determines the mode based on the internal winning combination (winning number). A transfer lottery process is executed (S372). Here, the sub CPU 82 shifts the game mode from the low probability mode to the high probability mode when a predetermined transition condition is satisfied, that is, when the high probability mode is selected (winning) as the game mode by the above-described mode transition lottery process. . On the other hand, when a predetermined end condition is satisfied, that is, the value set in the mode management counter is sequentially subtracted to 0 (that is, the number of games in the high probability mode becomes 0), the sub CPU 82 changes the game mode. Transition from high probability mode to low probability mode. The sub CPU 82 that performs such transition control constitutes a game mode control means.

  Next, the sub CPU 82 determines whether or not the high probability mode has been won in the above-described mode transition lottery process (S373). If the sub CPU 82 does not determine that the high probability mode has been won (NO), the sub CPU 82 ends the present subroutine.

  In S373, when determining that the high probability mode has been won (YES), the sub CPU 82 turns on the normal mode holding flag, sets 50 as the value of the mode management counter (S374), and ends this subroutine. To do.

<Processing during ART>
FIG. 48 is a flowchart showing the ART processing.

  First, the sub CPU 82 determines whether or not BB or RB (bonus) is included in the internal winning combination (S380). If the sub CPU 82 determines that a bonus is included in the internal winning combination (YES), it determines the bonus notification effect data during ART based on the internal winning combination (winning number) (S381), and ends this subroutine. To do.

  In S380, if the sub CPU 82 does not determine that the internal winning combination includes a bonus (NO), the sub CPU 82 determines the ART continuation effect data based on the internal winning combination (winning number) (S382). Here, when a so-called winning combination (especially, a small combination 1 to 3 corresponding to the RT transition pattern) is missed, the display combination corresponding to the internal winning combination cannot be won, the RT2 gaming state with a high probability of replay It will shift to RT1 gaming state with low replay probability. For this reason, in the process of S382, when the internal winning is made to the small roles 1 to 15 including the small roles 1 to 3, the player is notified of the correct positions of the small roles 1 to 15. Thereby, the player can win an internal winning combination by pressing the notification symbol. Therefore, the ART gaming state can be continued by preventing the internal winning combination corresponding to the small combinations 1 to 3 from being missed.

  Next, the sub CPU 82 determines whether or not the winning number of the internal winning combination is “20” (S383). When the sub CPU 82 determines that the winning number is “20” (YES), the current value of the ART game number counter and the game mode information (whether the mode is the low probability mode or the high probability mode) ) As special stock in the special stock storage area of the sub-RAM 83 (S384), and the process proceeds to S388.

  In S383, if the sub CPU 82 does not determine that the winning number is “20” (NO), the sub CPU 82 determines whether the winning numbers of the internal winning combination are “8” to “19” (S385). If the sub CPU 82 does not determine that the winning numbers are “8” to “19” (NO), it moves the process to S389.

  In S385, when the sub CPU 82 determines that the winning numbers are “8” to “19” (YES), the ART game number is added to the lottery table (FIG. 24) and based on the current game mode. An additional number of ART games is determined (S386). At this time, the sub CPU 82 adds a value corresponding to the determined number of added games (at least 10 games or more in the present embodiment) to the value of the current ART game number counter.

  Next, the sub CPU 82 determines whether or not the number of added games determined in S386 is 0 (S387). If the sub CPU 82 determines that the added game number is 0 (YES), it moves the process to S389. On the other hand, when the sub CPU 82 does not determine that the added game number is 0 (NO) or when the process of S384 is executed, the sub CPU 82 determines the ART game number additional effect data (S388).

  Next, when the sub CPU 82 determines that the added game number is 0 in S387 (YES), or when the process of S388 is executed, the sub CPU 82 decrements the ART game number counter by 1 (S389).

  Next, the sub CPU 82 determines whether or not the ART game number counter is 0 (S390). If the sub CPU 82 does not determine that the ART game number counter is 0 (NO), the sub CPU 82 ends the present subroutine.

  In S390, when determining that the ART game number counter is 0 (YES), the sub CPU 82 determines whether the ART counter is 1 or more and whether there is an ART stock (S391). . If it is not determined that the ART counter is 1 or more (NO), it is determined that there is no ART stock, and the process proceeds to S394. Here, the ART counter is for setting the number of ART sets for the prescribed number of games. In this embodiment, the ART counter is for setting the number of ART sets with 50 games as one set. For example, if the number of ART sets is 5, the value of the ART counter is 5.

  In S391, when the sub CPU 82 determines that the ART counter is 1 or more (YES), it sets 50 to the ART game number counter (S392), and subtracts 1 from the ART counter (S393), then this subroutine. Exit.

  Next, in S394, the sub CPU 82 determines whether or not the special stock is stored. If the sub CPU 82 does not determine that the special stock is stored (NO), the sub CPU 82 turns off the ART flag (S398), and ends this subroutine. As a result, the ART gaming state ends.

  In S394, when the sub CPU 82 determines that the special stock is stored and held (YES), the value of the ART game number counter stored and held as the special stock and the game mode information are restored ( S395). As a result, the number of ART games to be added becomes the remaining number of ART games when the watermelon corresponding to the winning number “20” is determined as the internal winning combination. Further, the game mode to return is the game mode at the time when the watermelon is determined as the internal winning combination. For this reason, the profit obtained by the player during the ART is not monotonous, and it is possible to provide a highly interesting gaming machine.

  Thereafter, the sub CPU 82 turns on the special stock return mode hold flag, and sets the value of the ART game number counter in the mode management counter (S396). That is, the same value as the value of the ART game number counter (the number of remaining games) at the time when the watermelon corresponding to the winning number “20” is determined as the internal winning combination is set as the value of the mode management counter. Thereby, the number of ART games added in S395 and the number of games in the game mode set in S396 become the same number of games.

  Here, in the present embodiment, the sub CPU 82 stores and holds as a special stock on condition that the ART game number counter is 0 (YES in S390) and the ART counter is 0 (NO in S391). Specific game state return means for returning the ART for the number of remaining games and returning the game mode stored and held as special stock is configured.

  Next, the sub CPU 82 clears the special stock returned in S395, that is, clears the special stock storage area of the sub RAM 83 (S397), and then ends this subroutine.

<Normal processing>
FIG. 49 is a flowchart showing normal processing.

  First, the sub CPU 82 determines whether or not BB or RB (bonus) is included in the internal winning combination (S410). If the sub CPU 82 determines that the internal winning combination includes a bonus (YES), the sub CPU 82 determines normal bonus notification effect data based on the internal winning combination (winning number) (S411), and executes this subroutine. finish.

  If the sub CPU 82 does not determine in step S410 that the internal winning combination includes a bonus (NO), the sub CPU 82 determines whether the ART counter is 1 or more (S412). That is, it is determined whether there is ART stock.

  If the sub CPU 82 determines that the ART counter is 1 or more (YES), it determines the ART transition effect data based on the internal winning combination (winning number) (S413), and ends this subroutine. By this processing, the player is notified of the type at the time of winning at least the small roles 1 to 3, the replays 2 to 4, and the replay 5.

  In S412, if the sub CPU 82 does not determine that the ART counter is equal to or greater than 1, that is, if there is no ART stock (NO), the ART lottery table (FIG. 26) is referred to to determine the game mode and the internal winning combination. The ART lottery process is executed based on (winning number) (S414).

  Next, the sub CPU 82 determines whether or not the ART has been won in the ART lottery process of S414 (S415). If the sub CPU 82 determines that the ART has been won (YES), the ART counter is incremented by 1 (S416), and the process proceeds to S417.

  In S415, if the sub CPU 82 does not determine that the ART has been won, that is, if the ART has not been won (NO), or if the process of S416 has been executed, the sub CPU 82 is usually based on the internal winning combination (winning number). Time effect data is determined (S417), and this subroutine is terminated.

<Display command reception processing>
FIG. 50 is a flowchart showing a subroutine of display command reception processing.

  First, the sub CPU 82 determines whether the BB is operating (S420).

  In S420, when determining that the BB is in operation (YES), the sub CPU 82 determines whether or not a winning combination 4 to 15 has been won (S421). If the sub CPU 82 does not determine that the winning combination 4 to 15 has been won (NO), this sub-routine ends.

  If the sub CPU 82 determines in S421 that the winning combination 4 to 15 has been won (YES), the ART counter is incremented by 1 (S422), and this subroutine is terminated.

  In S420, if the sub CPU 82 does not determine that the BB is in operation (NO), it determines whether the ART flag is on (S423).

  When determining that the ART flag is on (YES), the sub CPU 82 determines whether or not an RT transition symbol is displayed (S424). That is, it is determined whether or not an RT transition symbol (“Replay-Bell-Bell”) to be demoted from the RT2 gaming state on the main side to the RT1 gaming state is displayed (see FIG. 9). Here, demoting from the RT2 gaming state to the RT1 gaming state substantially means the end of the ART gaming state.

  If the sub CPU 82 does not determine that the RT transition symbol has been displayed (NO), the sub CPU 82 ends this subroutine, and if it determines that the RT transition symbol has been displayed (YES), it updates the ART game number counter to 0. (S425). That is, when the RT transition symbol (“Replay-Bell-Bell”) is displayed without following the notification of the seven symbols even though the seven symbols of the three-choice replay are notified during the ART, a penalty is given. To end the ART set.

  Next, the sub CPU 82 turns off the ART flag (S426), and then ends this subroutine.

  If the sub CPU 82 does not determine that the ART flag is on in S423 (NO), the sub CPU 82 determines whether replays 2 to 4 are displayed (S427). Here, replays 2 to 4 are promoted replays from the RT1 gaming state to the RT2 gaming state. That is, in S423, it is determined whether or not the transition from the RT1 gaming state to the RT2 gaming state is performed.

  If the sub CPU 82 does not determine that the replays 2 to 4 are displayed (NO), this sub-routine is terminated, and if it is determined that the replays 2 to 4 are displayed (YES), whether the ART counter is 1 or more. It is determined whether or not (S428). That is, it is determined whether or not there is an ART stock, and it is determined whether or not a condition that allows the sub-side to enter the AT game is satisfied.

  If the sub CPU 82 does not determine that the ART counter is 1 or more (NO), this sub-routine ends. If it determines that the ART counter is 1 or more (YES), the sub CPU 82 sets the ART game number counter to 50. Is set (S429).

  Next, the sub CPU 82 subtracts 1 from the ART counter (S430), turns on the ART flag (S431), and then ends this subroutine.

  As described above, the pachislot machine 1 according to the present embodiment is based on the condition that a predetermined small role (in this embodiment, the watermelon corresponding to the winning number “20”) is internally won during the operation of the ART. The sub CPU 82 stores and holds the number of remaining games of the ART when the small role is won and the game mode when the small role is won in the sub RAM 83 as a special stock. Further, on the condition that the number of games in ART (the number of unit games) has reached a predetermined number of games and the ART stock has run out, the sub CPU 82 performs ART for the number of remaining games stored and held in the sub RAM 83. Return. At this time, the sub CPU 82 restores the game mode stored and held in the sub RAM 83 as the game mode. That is, a special stock that fluctuates according to the number of games at the time of a predetermined small role winning (the number of remaining games of ART) and the game mode is added to the existing ART.

  Therefore, the benefit given to the player by adding the ART can be changed according to the number of games (the number of remaining games in the ART) and the game mode when a predetermined small role is won. For this reason, the profit given to the player during the operation of the ART does not become monotonous. As a result, the pachislot machine 1 according to the present embodiment can improve the interest of the player as compared with the conventional art with regard to the addition of ART.

<Other embodiments>
In the present embodiment, the game mode when the watermelon corresponding to the winning number “20” is internally won in S384 of FIG. 48 is stored and held by the same value as the value of the ART game number counter to be returned in S396. I have to. That is, in this embodiment, the game mode at that time is stored and held as a special stock regardless of whether the game mode when the watermelon is internally won is the low probability mode or the high probability mode. However, the present invention is not limited to this, and the high probability mode may be stored and held as a special stock only when the game mode when the watermelon is won internally is the high probability mode.

  In this case, if the number of games in ART reaches a predetermined number of games and the game mode when the ART stock runs out is the low probability mode, the game can be returned to the high probability mode again. When the mode is the high probability mode, the high probability mode can be continued. In other words, if the game mode at the time of internal winning of the watermelon is a low probability mode, this is not retained, so if the game mode is a high probability mode when the ART related to the special stock is restored, this is continued. be able to. Thus, since a game mode (low probability mode) that is relatively unfavorable for the player is not maintained, only a profit advantageous to the player can be given to the addition of ART.

  In the above-described example, only the high probability mode is stored and held as a special stock, and the number of games in the high probability mode restored in S396 in FIG. 48 is the number of ART games stored and held as a special stock when the watermelon is won internally. However, the present invention is not limited to this. For example, it may be as follows. That is, when the number of games in the high probability mode is smaller than the number of remaining games in the ART game when the watermelon is internally won during ART, the remaining number of games in the high probability mode when the watermelon is internally won May be stored as a special stock.

  In this case, the number of ART games to be returned as special stock can be made to depend on the number of remaining games in the high probability mode when the watermelon is won internally. Thus, for example, when the game mode is the low probability mode when the watermelon is won internally, the special stock may not be held, and the player can operate during the ART depending on the game mode when the watermelon is internally hit. It can change the benefits that are given.

  In this embodiment, the special stock is restored on condition that the ART game number counter is 0 (YES in S390 in FIG. 48) and the ART counter is 0 (NO in S391 in FIG. 48). (S395 and S396 in FIG. 48). However, the present invention is not limited to this. For example, the special stock may be returned on condition that the ART game number counter is zero. In this case, the next transfer ART set is activated after digesting the special stock. Thereby, when there are a plurality of ART sets, the special stock can be returned periodically, and the game during the ART can be changed.

  Further, in this embodiment, when the watermelon (winning number 20) is internally won during ART (YES in S383 in FIG. 48), the special stock is uniformly stored and held (S384 in FIG. 48). However, the special stock may be stored and held with a predetermined probability. Thereby, when a watermelon is won during ART, a player can have a sense of expectation as to whether or not he / she has won a special stock. In addition, it is possible to change the profit given to the player when winning a watermelon during ART. Further, in the case where special stock is stored and held with a predetermined probability, the probability of storing and holding the special stock may be changed according to the game mode when the watermelon is won internally. For example, when the game mode when the watermelon is won internally is the high probability mode, the probability of storing and holding the special stock is made higher than when the game mode is the low probability mode. Thereby, the presence or absence of special stock can be changed according to the game mode.
