Then, the power supply state to the main control board 63 and the sub control board 73 is controlled by controlling ON / OFF of the power supply switch 91 by the management CPU 81. Note that the power supply switch 91 is provided so that the power supply state of one of the main control board 63 and the sub control board 73 is controlled by the power supply switch 91 and the power supply is directly supplied from the power supply board 90 to the other. May be. By configuring in this way, for example, when an illegal act such as removing the ball management board 83 is performed, power is not supplied to the main control board 63, so that the game cannot be reliably performed. it can.

  Further, as shown in FIG. 3, an external inspection device P and the outgoing ball management board 83 (management CPU 81) are connectable via a dedicated interface (not shown).

(Main control board)
Next, the configuration of the main control board 63 will be described in detail. As shown in FIG. 6, the main control board 63 is realized by controlling various functions and hardware realized by executing a game control program 673 (see FIG. 3) stored in the ROM 67. Various functions are installed.

(1) Game control means 100
The game control means 100 in FIG. 6 performs control related to the game of the slot machine 1 and, as shown in FIG. 8, a special game (BB game (BB game) (BB game (BB game) having a higher probability of winning a small role than the normal game and the normal game). ') And RB game (RB')). As shown in FIG. 9, the normal game has a higher probability of winning for the general game (RT1) and the re-gamer than the general game. A game (RT4), an AT game (AT1) that suggests operating procedures of the stop switches 21L, 21M, and 21R advantageous to the player, and a special AT game (AT2) that is more advantageous than the AT game are included. . As will be described later, the AT game (AT1) and the special AT game (AT2) are executed in combination with either the general game (RT1) or the RT game (RT4), respectively. As shown in FIG. 6, the game control means 100 includes an operation mode determination means 100a and a game state setting means 100b.

a) Operation mode determination means 100a
The operation mode determination means 100a in FIG. 6 determines whether or not the player has operated the slot machine 1 and the mode of long press, for example. Specifically, both the bet switches 15 and 17, the start switch 19, and each stop switch 21L. , 21M, 21R, etc., various modes of operation of the slot machine 1 by the player, such as modes of operation by the player, and modes of the player's insertion of medals into the medal slot 25.

b) Game state setting means 100b
The game state setting means 100b (game state control means) of FIG. 6 is a result of the role lottery processing by the role lottery means 103 described later, and the display mode of the symbols of the reels 13L, 13M, 13R displayed on the display window 11. Based on the determination result by the symbol determination means 108, the gaming state of the slot machine 1 is set to any one of a plurality of preset gaming states having different advantages for the player.

  Specifically, as shown in FIG. 8, in a gaming state in which a normal game is executed, a predetermined special combination (BB, RB: see FIG. 11) is won (“7-7-7” on the winning line). BB winning if aligned and RB winning if “BAR-BAR-BAR” aligned on the winning line), the gaming state of the slot machine 1 is changed to a special game (BB game (BB ′), RB) by the gaming state setting means 100b. The game state in which the game (RB ′)) is executed is set. Then, in the BB game (BB ′), medals exceeding a predetermined number (for example, 300) are paid out, in the RB game (RB ′), there is a predetermined number of times (for example, eight times) small role winnings, If a special game end condition (BB ′ end condition, RB ′ end condition) is satisfied by the number of times (for example, 12 times) of games (games) being executed, the special game is ended and the slot machine 1 The gaming state is set to a gaming state in which a normal game is executed by the gaming state setting means 100b.

  In addition, as shown in FIG. 8, in a game state in which a normal game is executed, when a special combination is won but the special combination is not won, that is, each symbol corresponding to the special combination is displayed. When the reels 13L, 13M, 13R are not stopped so as to be displayed on the pay line set in the middle of the window 11, the gaming state of the slot machine 1 is the special role internal game (BB internal game ( RT2), the game state in which the RB internal game (RT3)) is executed is set by the game state setting means 100b. Also, in the special role internal game, by winning a special role that is carried over internally without winning, the game state of the slot machine 1 is set to a game state in which the special game is executed by the game state setting means 100b. Is done.

  The special game (BB game (BB '), RB game (RB')) is a game state in which the winning probability of a small role is higher than that of a normal game (such as a general game (RT1 ')).

  In addition, as shown in FIG. 9, in a normal game, a general game (RT1), a general game (RT1 + AT1) in which an AT game (AT1) is executed in a general game (RT1), and a special AT game (AT2) in a general game RT1 ) Is executed in the general special AT game (RT1 + AT2), the RT game RT4, the RT game (RT4), the ART game (RT4 + AT1) in which the AT game (RT4 + AT1) is executed, and the RT game (RT4) in the special AT game (AT2) One of the special ART games (RT4 + AT2) in which is executed is executed.

  The general game RT1 is a general game and is a game that is executed most frequently. The game state (the suggested game state) in which the AT game (AT1) is executed is a notification display to be described later for an operation procedure for stopping each reel 13L, 13M, 13R in the general game (RT1) or the RT game (RT4). By suggesting using 60 (see FIGS. 1 and 4) or the like, it is a gaming state that is more advantageous for the player than when not suggesting. A game in which an AT game (AT1) is executed in a general game (RT1) is referred to as a “general AT game (RT1 + AT1) (ART game preparation state)”, and an AT game (AT1) is executed in an RT game (RT4). This game is referred to as “ART game (RT4 + AT1)”. In addition, the AT game (AT1) ends when an AT game (AT1) of a preset number of digested games (for example, 50 games) is executed.

  The gaming state (suggested gaming state) in which the special AT game (AT2) is executed is the additional condition for adding the number of digested games (for example, 10 games), which is the end condition of the AT game (AT1). It is a gaming state in which a special AT game (AT2) is executed in a general game (RT1) or an RT game (RT4). Note that the special AT game (AT2) ends when a special AT game (AT2) with a preset number of games (for example, 10 games) is executed. Also, because the game state is different, the name is different from the above-mentioned AT game (AT1), but the special AT game (AT2) is similar to the AT game (AT1) in each reel by the notification display 60 or the like. By suggesting an operation procedure for stopping 13L, 13M, and 13R, the game is more advantageous to the player than when not suggesting. A game in which a special AT game (AT2) is executed in the general game (RT1) is referred to as a “general special AT game (RT1 + AT2)”, and a game in which the special AT game (AT2) is executed in the RT game (RT4). This is referred to as “special ART game (RT4 + AT2)”.

  The game state (specific game state) in which the RT game (RT4) is executed has a higher probability of winning a re-gamer who can play under the same conditions as the previous game without newly inserting medals from the general game (RT1). This is a high gaming state. As described above, the ART game (RT4 + AT1) is a game in which the AT game (AT1) is executed in the RT game (RT4), and the game state (specific game state) in which the RT game (RT4) is executed and the AT game. It is executed in a gaming state in which a gaming state in which (AT1) is executed (suggested gaming state) is combined. Further, as described above, the special ART game (RT4 + AT2) is a game in which the special AT game (AT2) is executed in the RT game (RT4), and the game state in which the RT game (RT4) is executed (specific game state) ) And a gaming state in which a special AT game (AT2) is executed (suggested gaming state). Note that an RT game (RT4) executed after shifting from an ART game (RT4 + AT1) may be referred to as a “general game standby game”.

  Also, as shown in FIG. 9, in the general game (RT1) or RT game RT4), if the AT1 transition condition is satisfied, the game state is set to the general AT game (RT1 + AT1) or ART game (RT4 + AT1) by the game state setting means 100b. ) Is set to be executed. On the other hand, in the general AT game (RT1 + AT1) or the ART game (RT4 + AT1), if the AT1 end condition is satisfied, the game state is set to the game state by the game state setting means 100b, and the game in which the general game (RT1) or RT game (RT4) is executed. Set to state. Further, as shown in FIG. 9, in the general AT game (RT1 + AT1) or the ART game (RT4 + AT1), if the AT2 transition condition is satisfied, the game state is set to the general special AT game (RT1 + AT2) or special by the game state setting means 100b. The game state in which the ART game (RT4 + AT2) is executed is set. On the other hand, if the AT2 end condition is satisfied in the general special AT game (RT1 + AT2) or the special ART game (RT4 + AT2), the game state is set by the game state setting means 100b, and the general AT game state (RT1 + AT1) or the ART game (RT4 + AT1) is set. The game state to be executed is set.

  Further, as shown in FIG. 9, in the general game (RT1), the general AT game (RT1 + AT1), or the general special AT game (RT1 + AT2), if the RT4 transition condition is satisfied, the game state is set to RT by the game state setting means 100b. A game state in which a game (RT4), an ART game (RT4 + AT1) or a special ART game (RT4 + AT2) is executed is set. On the other hand, as shown in FIG. 9, in the RT game (RT4), the ART game (RT4 + AT1), or the special ART game (RT4 + AT2), if the RT4 end condition is satisfied, the game state is changed to the general game ( RT1), a general AT game (RT1 + AT1), or a general special AT game (RT1 + AT2) is set to be executed.

  In addition, as described with reference to FIG. 8, when the special role (BB, RB) is won in the general game (RT1) or the RT game (RT4), the game state is set by the game state setting means 100b. When the game state is set to execute the BB internal game (RT2) or the RB internal game (RT3) and a special role (BB, RB) is won, the game state is set to BB game ( BB ′) or RB game (RB ′) is set to the game state in which it is executed. Further, when the special game is completed and the game is shifted to the normal game, the game state is set to the game state in which the general game (RT1) is executed by the game state setting means 100b, and the game is resumed.

  Further, when a special role (BB, RB) is won in a general AT game (RT1 + AT1), a general special AT game (RT1 + AT2), an ART game (RT4 + AT1), or a special ART game (RT4 + AT2), the game state setting means 100b When the game state is set to a game state in which the BB internal game (RT2) or the RB internal game (RT3) is executed and a special combination (BB, RB) is won, the game state is set by the game state setting means 100b. Is set to the gaming state in which the BB game (BB ′) or the RB game (RB ′) is executed, so that the general AT game (RT1 + AT1), the general special AT game (RT1 + AT2), the ART game (RT4 + AT1) or the special The ART game (RT4 + AT2) is temporarily interrupted.

  In addition, when a special game is executed after a general AT game (RT1 + AT1), a general special AT game (RT1 + AT2), an ART game (RT4 + AT1), or a special ART game (RT4 + AT2) is temporarily suspended, the special game ends. When the game state is shifted to the normal game, the game state is set by the game state setting means 100b and the general AT game (RT1 + AT1) or the general special AT game (RT1 + AT2) is executed according to the game state before the special game is executed. The general AT game (RT1 + AT1) or the general special AT game (RT1 + AT2) is resumed. If the RT4 transition condition (winning in any one of the replays 9 to 20) is established after the game is resumed, the number of digested games as the AT1 end condition is reduced to the remaining number of AT games (AT1) when interrupted when the special role is won. A game in which an ART game (RT4 + AT1) or a special ART game (RT4 + AT2) is executed by the game state setting means 100b by resetting a game number obtained by adding a predetermined number of games (for example, 10 games) to the number of digested games. Set to state. After this, if the AT1 end condition (execution of the number of digest games AT game (AT1)) is established, the game state is set to the RT game (RT4: general game standby state) independently by the game state setting means 100b. If the condition is set and the RT4 end condition (winning in any one of the winning combinations 1 to 12) is satisfied, the gaming state is set to the gaming state in which the general game (RT1) is executed by the gaming state setting means 100b. . When the general game (RT1) is temporarily interrupted and a special game is executed, the game state is set by the game state setting means 100b when the special game is completed and the game state is changed to the general game ( The gaming state in which RT1) is executed is set.

  Here, an outline of the game in the slot machine 1 will be described.

  The slot machine 1 is configured such that a game is executed when three medals are inserted. When the insertion sensor 53, the bet switch 15 or the maximum bet switch 17 detects insertion of three medals into the slot machine 1, A horizontal winning line (center line) at the center (middle stage) of the display window 11 becomes effective. Then, when the operation of the start switch 19 is detected on condition that three medals, which are the prescribed number, are inserted, any one of the preset winning lottery results will be described later by the lottery processing using random numbers. 103 (see FIG. 6). In addition, all rotations of the left, middle, and right reels 13L, 13M, and 13R are started, and the symbols of the reels 13L, 13M, and 13R displayed on the display window 11 are adjusted to the rotation angles of the reels 13L, 13M, and 13R. Start to determine.

  Thereafter, the left / middle / right reels 13L, 13M, and 13R are accelerated, and the operation of all the stop switches 21L, 21M, and 21R can be effectively received. After the operation of all the stop switches 21L, 21M, and 21R becomes valid, for example, when it is detected that the left stop switch 21L is operated, the left reel 13L is stopped and the operation of the middle stop switch 21M is detected. Then, the middle reel 13M is stopped, and when it is detected that the right stop switch 21R is operated, the right reel 13R is stopped. Thus, the operation of the stop switches 21L, 21M, and 21R stops the rotation of the left, middle, and right reels 13L, 13M, and 13R corresponding to the stop switches 21L, 21M, and 21R.

  When all three left / middle / right stop switches 21L, 21M, and 21R have been operated, the rotation of all three left / middle / right reels 13L, 13M, and 13R is stopped. At this time, when the symbol of the predetermined winning combination determined by the combination lottery means 103 stops at a predetermined position on the winning line in the middle stage of the display window 11 that has become valid, a winning is awarded, and the number of medals according to the winning mode Is credited or paid out from the medal payout opening 39, and one game is completed. In addition, instead of paying out medals or along with paying out medals, a predetermined profit may be given to the player.

  In the present embodiment, as shown in FIG. 10, as a combination, a special combination (bonus: BB, RB), a small combination (middle bell, one-piece combination 1 to 12, middle cherries, watermelon), re-playing combination (Replay 1) To 26) are preset. As shown in FIGS. 11 and 12, in the present embodiment, as the result of lottery drawing, different combinations (“middle stage bell”, “single piece combination 1” to “single piece combination 12”, “ There is a possibility of winning a duplicate winning combination (winning role group: left bell / middle bell / right bell / replay A to D) that may be matched with “Replay 1” to “Replay 26”). Then, the role lottery results of the role lottery means 103 include special role winning (bonus winning), small role winning, re-game winning (replay winning), and loss.

  In addition, the prizes include special prizes (bonus prizes) related to transition to special games (bonus games), small prizes related to medal payouts, and re-game prizes related to execution of replays (replays) ( Replay winning).

  Then, for example, when three symbols of each reel 13L, 13M, 13R are arranged on the winning line in each display mode relating to the roles “BB” and “RB” in FIG. Game) is executed.

  In this embodiment, there is no medal payout due to the special role winning (the specified payout number for the special role is 0), and the game is shifted to the bonus game after the game in which the winning mode related to the special role is established. Alternatively, a predetermined payout number (for example, 10) may be set for the special combination, and the bonus game may be started after paying out medals.

  Further, for example, the symbols of the reels 13L, 13M, and 13R are displayed in the display windows in the display modes related to the roles “middle bell”, “single ball 1” to “single ball 12”, “middle cherry”, and “watermelon” in FIG. When three pieces are arranged on the middle 11 winning line, it becomes a small role winning, and the number of medals shown in the “paid out number” column is paid out.

  Further, in FIG. 10, “any” used as the display mode relating to the winning of the middle “cherry” cherry may be arranged on the winning line on any of the symbols provided on the middle reel 13M and the right reel 13R. It means that.

  In addition, when three symbols on each of the reels 13L, 13M, and 13R are arranged on the winning line in the display modes related to the roles “Replay 1” to “Replay 26” in FIG. The game can be played again under the same conditions as the previous game without throwing it in.

  By the way, in this embodiment, it is comprised so that a plurality of winning combinations can be won simultaneously by the winning lottery means 103. That is, as shown in the tables of FIG. 11 and FIG. 12, a winning combination group (combination lottery result) composed of a plurality of combinations is formed, and whether or not each winning combination group has been won is determined by the combination lottery means 103. It is drawn by. As shown in FIG. 11, among the winning group, the winning group “left bell”, “middle bell”, “right bell” (hereinafter, the winning group “left bell”, “middle bell”, “right bell” are collectively shown. The winning group “left bell”, “middle bell”, and “right bell” may also be referred to as “specific set winning”), respectively, include. Specifically, the winning role group “left bell” is composed of “middle bell”, “one piece role 1” to “one piece role 4”, and the winning role group “middle bell” includes “middle bell” and “one”. The winning combination group “right bell” is composed of “middle bell”, “single portion 9” to “single portion 12”.

  Therefore, if it is determined by the winning lottery means 103 that the winning group “left bell” has been won, it means that the “middle bell”, “single winning 1” to “single winning 4” are won simultaneously, If it is decided that the role group “Middle Bell” has been won, it means that “Middle Bell”, “One Piece Role 5” to “One Piece Role 8” will be won at the same time, and the elected role group “Right Bell” will be won. If it is determined, “middle stage bell”, “single piece combination 9” to “single piece combination 12” are won simultaneously.

  In the present embodiment, the operating modes (push order) of the stop switches 21L, 21M, and 21R that are advantageous to the player are set in advance for each of the winning combination groups “left bell”, “middle bell”, and “right bell”. As shown in the “Remarks” column of the table of FIG. 11, even if the role lottery result (winning role group) by the role lottery means 103 is the same, the player can select each stop switch 21L, 21M, The stop control means 107 (see FIG. 6) is configured to stop and control the reels 13L, 13M, and 13R so that the winning mode (display mode) varies depending on the order in which the 21Rs are operated.

  That is, by winning each of the winning combination groups “left bell”, “middle bell”, and “right bell” shown in FIG. 11, when a plurality of winning combinations are simultaneously won, the stop switches 21L, 21M, Corresponding to the operation order of 21R, the stop control means 107 is configured so that, among the winning combinations, the combination for preferentially aligning the winning symbols on the winning line is different.

  Specifically, as shown in FIG. 11, for example, when the winning lottery result by the winning lottery means 103 is winning the winning combination group “left bell”, the left stop switch 21L is first displayed by the operation mode determining means 100a. If it is determined that the operation is performed, the symbol “Bell”, which is the display mode corresponding to the winning combination “middle bell” that is most advantageous to the player, is displayed in a state where the symbols are aligned on the winning line. The reels 13L, 13M, and 13R are controlled to be stopped by the stop control means 107.

  On the other hand, when the operation mode determination means 100a determines that the left stop switch 21L has not been operated for the first time, the symbol “Bell” corresponding to the winning combination “middle bell” is aligned on the winning line. The symbol is not displayed in the state. That is, it is determined by the operation mode determination means 100a that the stop switches 21L, 21M, and 21R are operated in a predetermined operation order corresponding to the winning combination group (“left bell”, “middle bell”, “right bell”). Unless it is done, the symbol is not displayed in the display mode corresponding to the winning combination that is most advantageous to the players included in the winning combination group.

  Also, as shown in FIG. 12, among the winning group, the winning group “Replay A” “Replay B” “Replay C” “Replay D” (hereinafter, the winning group “Replay A” “Replay B” “ Each of “Replay C” and “Replay D” may be referred to as “specific set winning”) includes a plurality of winning combinations. Specifically, the winning combination group “Replay A” includes “Replay 1” to “Replay 22”, and the winning combination group “Replay B” includes “Replay 1” to “Replay 20”, “Replay 23”, and “Replay 23”. The winning group “Replay C” is composed of “Replay 1” to “Replay 20”, “Replay 25”, and “Replay 26”, and the winning group “Replay D” is “Replay 21”. To “Replay 26”.

  Therefore, if the winning lottery means 103 determines that the winning group “Replay A” is won, it means that “Replay 1” to “Replay 22” are won simultaneously, and the winning group “Replay B” is won. If it is determined that “Replay 1” to “Replay 20”, “Replay 23”, and “Replay 24” have been won simultaneously, and if it is determined that the winning group “Replay C” has been selected, “Replay” If “1” to “Replay 20”, “Replay 25” and “Replay 26” are won simultaneously, and it is determined that the winning group “Replay D” is won, then “Replay 21” to “Replay 26” are simultaneously selected. It will be elected.

  In the present embodiment, the operating modes (push order) of the stop switches 21L, 21M, and 21R that are advantageous to the player are set in advance for each of the winning combination groups “Replay A”, “Replay B”, and “Replay C”. As shown in the “Remarks” column of the table of FIG. 12, even if the role lottery result (winning role group) by the role lottery means 103 is the same, the player can select the stop switches 21L, 21M, The stop control means 107 is configured to stop and control the reels 13L, 13M, and 13R so that the winning mode (display mode) varies depending on the order in which 21R is operated. In addition, as shown in the “Remarks” column of FIG. 12, the winning combination group “Replay D” is determined according to the order in which the player operates the stop switches 21L, 21M, 21R. The stop control means 107 is configured to stop and control the reels 13L, 13M, and 13R so that the aspect) is different.

  That is, each of the winning switch groups “Replay A”, “Replay B”, “Replay C”, and “Replay D” shown in FIG. Corresponding to the operation order of 21L, 21M, and 21R, the stop control means 107 is configured so that among the winning combinations, the combination for preferentially aligning the symbols related to winning on the winning line is different.

  Specifically, as shown in FIG. 12, for “Replay A”, “Replay B”, and “Replay C” for which an operation mode advantageous to the player is set, for example, the winning lottery result by the winning lottery means 103 is the winning group. When “replay A” is won and the operation mode determination means 100a determines that the left stop switch 21L is operated first, the winning combinations “replay 9” to “replay 9” to “ The reels 13L, 13M, and 13R are controlled to be stopped by the stop control means 107 so that the symbols are displayed in a state in which the symbols are aligned on the winning line in a display mode corresponding to any of “Replay 20”.

  On the other hand, when it is determined by the operation mode determination means 100a that the left stop switch 21L has not been operated for the first time, the symbol is awarded in a display mode corresponding to any of the winning roles “Replay 9” to “Replay 20”. The symbols are not displayed in a state of being aligned on the line. That is, it is determined by the operation mode determination means 100a that the stop switches 21L, 21M, and 21R are operated in an operation sequence set in advance corresponding to the winning combination group (“Replay A”, “Replay B”, and “Replay C”). Unless it is done, the symbol is not displayed in a display mode corresponding to the winning combination advantageous to the players included in the winning combination group.

  Note that the winning combination group “Replay D” is configured to win only in the special role internal game (BB internal game (RT2), RB internal game (RT3)). Therefore, when the symbols are arranged on the winning line in a display mode corresponding to any of the winning roles “Replay 21” to “Replay 26” constituting the winning role group “Replay D”, the player can play the special role internal game. It can be recognized that (BB internal game (RT2), RB internal game (RT3)) is being executed.

  By the way, special games (BB game (BB ′), RB game (RB ′)) are games in which the winning probability of a small role is set higher than that of normal games, and game medals are easily paid out. The game is more advantageous to the player than the game, and the player can acquire more medals. When the special game “RB” in FIG. 10 is won to shift to a special game, a regular bonus game (RB game (RB ′)) is executed.

  In the regular bonus game, the role lottery table 671 (see FIG. 6) that defines the winning probability of the lottery process by the role lottery means 103 is determined based on the lottery process by the role lottery means 103 from the normal game lottery table selected in the normal game. By switching to a special game lottery table that is defined with a higher probability of winning than in a normal game, the winning probability of a small role is set to be higher than in a normal game. As a result, the special game is a game that is more advantageous to the player than the normal game. Then, after the transition to the regular bonus game, a predetermined number of times, for example, 12 games are played, or when a small role is won 8 times, the regular bonus game is ended and the game shifts to a normal game.

  Further, when the special game “BB” in FIG. 10 is won to shift to a special game, a big bonus game (BB game (BB ′)) is executed. In the big bonus game, the regular bonus game described above is continuously executed. After the transition to the big bonus game, the big bonus game is ended when a predetermined number of medals (for example, 300) are paid out. In other words, the big bonus game is set to end the special game (big bonus game) and shift to the normal game when the number of medals paid out in the big bonus game reaches a predetermined upper limit number.

  As described with reference to FIG. 8, when the result lottery result of the role lottery means 103 becomes the special role winning (BB, RB), the symbol stop control based on the special role winning is performed. If the symbol arrangement of the special role winning mode is not allocated, the game shifts to the special role internal game (BB internal game (RT2), RB internal game (RT3)). It is carried over until the symbol arrangement of is allocated.

  On the other hand, the small role winning is not carried over to the next game unless the symbol arrangement of the winning combination of the small role is assigned in the game in which the winning combination lottery result is the small role winning. Further, in the case of replay winning, regardless of the timing at which each of the stop switches 21L, 21M, 21R is operated, the symbol (“R1” “R2”) related to any one of “Replay 1” to “Replay 26”. Since the symbols are arranged on the left, middle and right reels 13L, 13M, and 13R so that "7", "Watermelon", "Cherry", and "Bell") are always aligned on the winning line, the player will always win the re-playing role.

  In addition, when any of the winning group “left bell”, “middle bell”, and “right bell” is won, the stop switches 21L, 21M, and 21R are operated at any timing as in the case of the replay symbol. However, the left, middle and right reels 13L and 13M so that the symbols (“Bell”, “R1” and “R2”) related to the winning group “left bell”, “middle bell” and “right bell” are always aligned on the winning line. , 13R, the winner is always awarded one of the "middle bell", "single piece combination 1" to "single piece combination 12". That is, when one of the winning combination groups “left bell”, “middle bell”, “right bell”, “replay A”, “replay B”, “replay C”, and “replay D” is won, the respective stop switches 21L, 21M, 21R are selected. When the stop switch 21L, 21M, 21R is operated at any timing, the winning symbols associated with each operation mode (see FIG. 10) are aligned on the winning line. The reels 13L, 13M, 13R are controlled to be stopped by the stop control means 107.

  In addition, as shown in FIG. 9, if the AT1 transition condition is satisfied in the general game (R1), the game is shifted to the AT game (AT1) (AT (assist time) period). In AT game (AT1), when winning either “Left bell”, “Middle bell”, “Right bell”, “Replay A”, “Replay B”, or “Replay C”, the type of winning group (specific set winning) The player is notified of an operation mode (which stop switch should be operated first) advantageous to the player according to the game. Specifically, when one of “left bell”, “middle bell”, and “right bell” is won, the number of medals to be paid out is 10 as shown in FIG. The operation mode of the stop switch is notified so that the “middle bell” wins. Further, when one of “Replay A”, “Replay B”, and “Replay C” is won, the RT4 transition condition is satisfied as shown in FIG. 9 so that the RT game (RT4) is entered. The operation mode of the stop switch for winning the “Replay 9” to “Replay 20”, which is the RT4 transition condition shown in FIG. Then, after shifting to the AT period, when the number of digestion games set in advance, for example, 50 AT games (AT1) is performed and the AT1 end condition is satisfied, the AT period ends.

  In the present embodiment, as shown in FIG. 9, after the RT4 transition condition is established and the transition to the ART game (RT4 + AT1) is made, any of “Replay A”, “Replay B”, and “Replay C” is won. In addition, although it is configured not to notify the operation mode of the stop switch that wins “Replay 9” to “Replay 20”, this operation mode may be notified. In addition, “Replay A”, “Replay B”, and “Replay C” are each configured to win with the same probability, and after moving to RT game (RT4), “Replay A” is more effective than general game (RT1). The winning probability for “Replay B” and “Replay C” is configured to be high.

(2) Setting control means 101
The setting control unit 101 in FIG. 6 sets setting values (setting 1 to setting 6). This set value is for selecting a combination lottery table 671 selected by the table selection means 102 to be described later, and each of the set values corresponds to each of a plurality of combination lottery tables 671 stored in the ROM 67. It is attached. Then, the setting control means 101 determines the ON / OFF state of the change process start switch 56 (FIG. 4) when the power is turned on. When the power is turned on while the change process start switch 56 is ON, a predetermined setting change is made. Start processing.

  Here, the winning probabilities in the normal game lottery are set in a plurality of stages distinguished by a plurality of types of setting values (here, six types), and each of the plurality of setting values has a role lottery table shown in FIG. 671 (normal game lottery table) is associated. When the setting change process is started, the manager of the pachinko hall where the slot machine 1 is installed can change the setting value.

  This procedure is performed as follows, for example. That is, the administrator opens the front door 5, inserts a setting change key (not shown) into the key cylinder of the operation box 49 and rotates with the power switch 50 turned off, and turns on the change processing start switch 56. To. In this state, the setting change process is started by turning on the power switch 50.

  Then, the winning probability setting value is cyclically switched from setting 1 to setting 6 for each operation of the setting change button 52 by the administrator. This set value is notified by displaying 1 to 6 by a 7 segment type set value display LED, for example. When the set value of the winning probability becomes a desired value by operating the setting change button 52 (the display value of the setting value display LED becomes a desired value), the set value is determined by operating the start switch 19. . Then, when the setting change key inserted in the key cylinder is rotated and the change process start switch 56 is turned OFF, the setting change process ends. Thereafter, when a medal is inserted from the medal slot 25, the game is started.

(3) Table selection means 102
The table selection means 102 of FIG. 6 is set by the setting control means 101, the type of game (normal game, RT game, special role internal game, special game, etc.) controlled by the game control means 100 on the main control board 63. One lottery table is selected from a plurality of combination lottery tables 671 shown in FIG. 6 based on the set value (setting 1 to setting 6). That is, for example, in a normal game, the table selection means 102 selects a combination lottery table 671 (normal game lottery table) as a lottery table according to the set value (setting 1 to setting 6) of the winning probability.

(4) Role lottery means 103
As shown in FIGS. 11 and 12, the combination lottery means 103 shown in FIG. 6 has a plurality of combination lottery results (special combination winning, small combination winning, re-game winning combination, loss) at the timing when the start switch 19 is operated. Is selected and determined by a lottery process using a random number and a lottery table as a result lottery result in the current game, a random number generating means, a random number extracting means, a lottery table, and a lottery Judgment means is provided. Here, the random number generating means generates a random number for lottery within a predetermined range (for example, 0 to 16383 in decimal number), and counts the oscillation circuit and the clock signal generated by the oscillation circuit. Counter circuit. Further, the random number extraction means extracts the random number generated by the random number generation means at the timing when the start switch 19 is operated. Since the random number generating means is constituted by a counter circuit or the like, the numerical value generated by the random number generating means is not strictly a random number. However, since the timing at which the start switch 19 is operated is considered to be random, the numerical value extracted by the random number extraction means can be practically handled as a random number. A random number may be generated by a random number generator.

  Further, the role lottery table 671 of FIG. 6 is predetermined for each random number within the range generated by the random number generation means, and whether or not it corresponds to any of the preset role lottery results, The random number extracted by the random number extraction means is compared with the lottery table to determine which of the plurality of lottery results the extracted random number corresponds to.

(5) Notification determining means 104
The notification determination means 104 of FIG. 6 determines whether to notify the operation mode of the stop switches 21L, 21M, and 21R advantageous to the player. For example, even if the role lottery result is “right bell”, if the player cannot know that fact, the player does not always operate the right stop switch 21R first, and the “middle bell” is displayed. It is not always possible to align. On the other hand, in an AT game, when the result lottery result becomes “right bell”, the fact is notified, and the player is prompted to operate the right stop switch 21R first, thereby increasing the chance that the player receives a payout. It becomes possible.

  Also, for example, even if the winning lottery result is “Replay C”, if the player cannot know that fact, the player does not always operate the right stop switch 21R first, and “Replay 9”. ~ "Replay 20" cannot always be aligned. On the other hand, in the AT game, when the result of lottery becomes “Replay C”, the fact is notified, and the right stop switch 21R is first operated, so that the RT game (RT4) advantageous to the player can be realized. It will be possible to increase the opportunities for transition.

  Here, as shown in FIG. 9, when the AT1 transition condition is satisfied, it is determined that the notification is determined by the notification determination unit 104, and the status of the AT period flag and the AT1 flag stored in the flag storage unit 651 is set. The game state is set to ON, and the game state is set to a game state in which the AT game (AT1) is executed by the game state setting means 100b. In addition, the state of the AT period flag and the AT1 flag stored in the flag storage unit 651 is set to OFF when a predetermined number of digest games (for example, 50 times) are executed, and the game state is set. The game state setting means 100b sets the game state in which the general game (RT1) is executed alone. For example, by assigning any one of the bits in the 1-byte memory area forming the flag storage unit 651 to the AT period flag and the AT1 flag, and setting the ON / OFF of the bit, during the AT period The state of the flag and the AT1 flag can be stored in the flag storage unit 651.

  Specifically, as shown in FIG. 9 and FIG. 11, after winning the next game won in the “middle cherries” or the transition lottery executed with a 1/2 winning probability at the time of “watermelon” winning, The AT1 transition condition is established after the predetermined number of games set as the precursor period have been consumed. In addition, when winning the transition lottery at the time of “watermelon” winning, for example, the number of games of 4 to 32 games is set as a precursor period by lottery.

  In the AT game (AT1), as described above, each of the winning groups “left bell”, “middle bell”, “right bell”, “replay A”, “replay B”, and “replay C” is won. An operation mode (operation order) advantageous to the player set in advance in the combination group is notified to the player. Then, after shifting to the AT period (AT game (AT1)), when the AT game (AT1) with the preset number of digested games is performed, the AT period ends.

  Further, as shown in FIG. 11, in the AT game (AT1), when the winning combination group “watermelon” is won, the extra lottery for determining whether or not to add to the number of digested games as the AT1 end condition is 1/2. The winning condition is established when the player wins, and a predetermined additional number (for example, 10 games) is added to the number of digested games.

  Further, as shown in FIGS. 9 and 11, when the winning combination group “Cherry” is won in the AT game (AT1), the AT2 transition condition is satisfied, and the state of the AT1 flag stored in the flag storage unit 651 is set to OFF. Then, the state of the AT2 flag is set to ON, and the gaming state is set to a gaming state in which the special AT game (AT2) is executed by the gaming state setting means 100b. Thereafter, when a predetermined number of games (for example, 10 times) of special AT games (AT2) are executed, the state of the AT1 flag stored in the flag storage means 651 is set to ON and the state of the AT2 flag is turned OFF. The gaming state is set to a gaming state in which the AT game (AT1) is executed by the gaming state setting means 100b. Similar to the AT period flag and the AT1 flag, for example, one of the bits of the 1-byte memory area forming the flag storage unit 651 is assigned to the AT2 flag, and the bit is set to ON or OFF. Thus, the state of the AT2 flag can be stored in the flag storage unit 651.

  Further, as shown in FIG. 11, in the special AT game (AT2), in addition to the above-mentioned lottery at the time of winning the winning group “watermelon”, any of the winning group “left bell”, “middle bell”, “right bell” When the crab is won, an extra lottery for determining whether or not to add to the number of digestion games, which is an AT1 end condition, is executed with a winning probability of 1/2. When an extra lottery is won, an additional condition is established, and a predetermined additional number (for example, 10 games) is added to the number of digested games.

(6) Command creation means 105
The command creation means 105 in FIG. 6 includes data relating to the role lottery result in the role lottery process by the role lottery means 103, and data relating to the operation of the operating instruments operated by the player such as the stop switches 21L, 21M, and 21R A command for transmitting various data such as, etc. to the sub control board 73 (sub CPU 71) is generated. The command generated by the command creating unit 105 is transmitted to the sub control board 73 by the sub control command transmitting unit 110 described later.

  The command creation unit 105 creates a command according to the determination result of the notification determination unit 104. That is, the notification determining unit 104 uses the command created by the command creating unit 105 as a command that can identify the type of specific set winning (a command that can be used to identify an advantageous operation mode), or a command that cannot identify the type of specific set winning ( It also has a function of determining whether the command is an advantageous operation mode.

  Specifically, as shown in FIG. 11 and FIG. 12, the command creation means 105 has “0” to “13” as commands that can identify the lottery result when the lottery by the combination lottery means 103 is executed. Create a command that contains. As will be described later, the sub control board 73 selects an effect to be executed based on the sent command. In other words, the command creation means 105 creates a command that indicates the contents of the effect executed on the sub control board 73.

  When the notification determination unit 104 determines that the operation mode advantageous to the player is not notified, that is, when the flag during the AT period is set to OFF, the command creation unit 105 A command is created that does not include data indicating the type of the winning combination group (“left bell”, “middle bell”, “right bell”) that can be identified as having won the crab but cannot identify the corresponding winning group. Further, when it is determined by the notification determining means 104 that an operation mode advantageous to the player is notified, that is, when the AT period flag is set to ON, the winning combination group (“left bell” “middle bell” is selected. “Right bell”) is included, and a command that can identify the corresponding winning group is created.

  Specifically, as shown in FIG. 11, when the flag during the AT period is OFF, the command creation means 105 is selected when any of the winning group “left bell”, “middle bell”, or “right bell” is won. Even if it exists, the same command “No. 1” is created so that it is not possible to identify which winning group of the “bell group”. On the other hand, the command creating means 105 selects the “second bell” command when the “left bell” is won when the AT period flag is ON, and the “third” command when the “middle bell” is won. If “Right Bell” is won, “No. 4” command is created.

  Similarly, when the flag during the AT period is set to OFF, the command creation means 105 can identify that “Replay A”, “Replay B”, “Replay C”, or “Replay D” has been won. However, a command that does not include data indicating the type of the winning combination group (“Replay A”, “Replay B”, “Replay C”, “Replay D”) that cannot be identified is created. In addition, when the AT period flag is set to ON, data indicating the type of the winning combination group (“Replay A”, “Replay B”, “Replay C”, “Replay D”) that is won is included and the corresponding winning combination is included. Create a command that can identify the group.

  For example, as shown in FIG. 12, when the flag during the AT period is OFF, the command creation means 105 is selected when any of the winning group “Replay A”, “Replay B”, “Replay C”, or “Replay D” is won. Even if it exists, the same command “No. 9” is created so that it cannot be identified which winning group. On the other hand, the command creating means 105 selects the “10th” command when “Replay A” is won when the AT flag is ON, and the “11” command when “Replay B” is won. When “Replay C” is won, a “12th” command is created, and when “Replay D” is won, a “13th” command is created.

  The command creation means 105 creates the same command for the other lottery results, regardless of whether the AT period flag is ON or OFF. That is, if the “middle cherry” is won, the command “No. 5” is given, the command “No. 6” is won if the “watermelon” is won, and the command “7” if the “BB” is won. If “RB” is won, a command “8” is created. In case of a loss, a command “No. 0” is created.

(7) Reel detecting means 106
The reel detection means 106 in FIG. 6 sends detection signals from the left / middle / right position sensors 55L, 55M, and 55R to the reel motors 14L, 14M, and 14R that drive the left, middle, and right reels 13L, 13M, and 13R. Based on the number of supplied pulses, the rotational positions of the left, middle, and right reels 13L, 13M, and 13R are detected. This reel detection means 106 corresponds to a symbol located at a predetermined reference position (for example, the middle stage of the display window 11 in this embodiment) while the left, middle, and right reels 13L, 13M, 13R are rotating and stopped. Each frame number is detected.

(8) Stop control means 107
The stop control means 107 in FIG. 6 performs stop control of each reel 13L, 13M, 13R using the stop table 672 based on the operation of each stop switch 21L, 21M, 21R, and is variable by each reel 13L, 13M, 13R. Each displayed symbol is stopped in a display mode corresponding to the winning lottery result of the winning lottery means 103. This stop control means 107 performs stop control of each reel 13L, 13M, 13R for each game based on the winning lottery result determined by the winning lottery means 103 and the operation mode of each stop switch 21L, 21M, 21R.

  As shown in the “Remarks” column in the tables of FIGS. 11 and 12, the winning group “left bell” “middle bell” “right bell” “replay A” “replay B” “replay C” When one of “Replay D” is won, the matching combination is set differently depending on the first stop switch to be operated. Further, the operation mode that is advantageous differs depending on the types of winning combination groups “left bell”, “middle bell”, “right bell”, “replay A”, “replay B”, and “replay C”.

  In the stop table 672 (see FIG. 6) for determining the stop positions of the reels 13L, 13M, and 13R, a plurality of tables are set corresponding to each of the winning lottery results of the winning lottery means 103. The stop table 672 is a table in which the number of sliding frames of each reel 13L, 13M, 13R is determined in advance according to the rotational position of the reels 13L, 13M, 13R when the stop switches 21L, 21M, 21R are operated. The reels 13L, 13M, and 13R are formed so that the number of sliding frames is different corresponding to the stop operation order of the corresponding stop switches 21L, 21M, and 21R.

  If the winning lottery result of the winning lottery means 103 is a win for any of the winning combinations, the stop control means 107 and the stop table 672 selected based on the winning lottery result and the stop switches 21L, 21M, From the rotational position of each reel 13L, 13M, 13R when 21R is operated, the number of sliding frames of each reel 13L, 13M, 13R is determined so as to win the winning combination, and each reel 13L, 13M, 13R is determined. Perform stop control. On the other hand, if the winning lottery result by the winning lottery means 103 is lost, the stop control means 107 has operated the stop table 672 selected based on the lost winning lottery result and the stop switches 21L, 21M, 21R. From the rotational position of each reel 13L, 13M, 13R, the number of sliding symbols of each reel 13L, 13M, 13R is determined so as not to win any of a plurality of roles, and each reel 13L, 13M, 13R Perform stop control.

  By the way, there is an upper limit on the number of sliding frames, and if the stop switches 21L, 21M, and 21R are not operated at the timing when the reels 13L, 13M, and 13R are respectively at predetermined rotational positions, the stop control means 107 is Even if the winning lottery result by the winning lottery means 103 is a win for any of the winning combinations, the reels 13L, 13B, and 13D are displayed so that the symbols displayed on the display window 11 are stopped and displayed in a winning manner corresponding to the winning winning combination. 13M and 13R cannot be controlled to stop. In other words, the stop control unit 107 determines that the stop switches 21L, 21M, and 21R are operated at the timing when the reels 13L, 13M, and 13R are at predetermined rotation positions based on the combination lottery result of the combination lottery unit 103. The reels 13L, 13M, and 13R are controlled to stop so that the symbols displayed on the display window 11 are stopped and displayed in a winning manner corresponding to the winning combination.

(9) Symbol determination means 108
The symbol determination means 108 in FIG. 6 has the reels 13L, 13M, 13R detected by the reel detection means 106 and stopped by the stop control means 107 based on the respective rotational positions. It is determined whether or not the display mode of each symbol is a predetermined display mode.

  When the symbols are arranged on the winning line in the display mode shown in the combinations “BB” and “RB” in FIG. When the symbols are aligned on the winning line in the display manners shown in “middle bell”, “single piece 1” to “single piece 12”, “middle cherry”, and “watermelon” in FIG. The winning combination is determined, and the symbol determining unit 108 determines that the winning combination is a re-game winning when the symbols are arranged on the winning line in the display modes shown in “Replay 1” to “Replay 26” in FIG.

(10) Dispensing control means 109
The payout control means 109 (grant control means) in FIG. 6 gives a predetermined profit to the player based on the determination result by the symbol determination means 108. The payout control means 109 determines that the number of credit medals stored is the upper limit value (this embodiment) if the symbol determination means 108 determines that one of a plurality of winning combinations has been won, and if there is a medal payout. After reaching 50, for example, the hopper unit 43 is operated to pay out medals by the payout number corresponding to the winning combination. Further, the payout control means 109 increases the credit medals by the payout number instead of the operation of the hopper unit 43 as a medal payout until the number of stored credit medals reaches the upper limit value.

  By the way, when the symbol determining means 108 determines that the re-game player has won a prize, the payout control means 109 assumes that a prescribed number (three) of medals have been inserted and validates the winning line of the next game. To do.

(11) Sub-control command transmission means 110
The sub-control command transmission unit 110 in FIG. 6 transmits commands including various data created by the command creation unit 105 from the main control board 63 to the sub-control board 73 as predetermined information through one-way communication. This sub-control command transmission means 110 is created by the command creation means 105 and set by the setting control means 101, gaming state such as normal game and special game, the role lottery result of the role lottery means 103, symbol determination A command including data representing the state of the slot machine 1 such as a symbol determination result by the means 108, a rotation / stop state of each reel 13L, 13M, 13R, a medal payout state by the payout control means 109, etc. is transmitted to the sub-control board 73. .

  Further, the sub control command transmission means 110 transmits a command created by the command creation means 105 including data indicating the detection state of the inserted medal by the insertion sensor 53, the operation state of the bet switch 15 and the maximum bet switch 17, and the like. 73. The sub-control command transmission means 110 sub-controls commands created by the command creation means 105 including data indicating that various switches such as the start switch 19 and the stop switches 21L, 21M, and 21R have been operated by the player. Transmit to the board 73.

(12) Notification means 111
The notification means 111 in FIG. 6 is flagged when it is determined by the notification determination means 104 to execute a predetermined effect that notifies the operation mode of each of the stop switches 21L, 21M, 21R advantageous to the player, that is, during the AT period. Is set to ON, the result lottery result of the role lottery means 103 is any of the winning group “left bell” “middle bell” “right bell” “replay A” “replay B” “replay C”. If the number is one, the operation sequence of the stop switches 21L, 21M, 21R advantageous to the player corresponding to the winning winning group is displayed on the notification display 60 directly controlled by the main control board 63. By doing so, an effect is provided in which an operation mode advantageous to the player is notified. Specifically, when an operation mode advantageous to the player “operates the left stop switch 21L first” is set in the winning combination group, “123” or “ “1--” is displayed. Note that the notification unit 111 may display the information indicating the type of the winning combination group won by the notification display 60.

  Further, when it is determined by the notification determining means 104 that a predetermined effect for notifying the player of an advantageous operation mode is not executed, that is, when the flag during the AT period is set to OFF, the notification means 111 In order not to know the operation mode advantageous to the player, the display according to the winning lottery result is performed on the notification display 60, and the effect of notifying the operation mode advantageous to the player is not performed.

(13) Door opening / closing detection means 112
6 detects the open / closed state of the front door 5 based on the detection signal of the door sensor 58.

(14) Data management means 113 for payout management
The outgoing ball management data transmission means 113 (information transmission means) in FIG. 6 sends the ID data 120 shown in FIG. 13 and the log data 121 shown in FIG. 14 to the outgoing ball management board 83 without passing through the sub-control board 73. Send. The outgoing ball management data transmission means 113 has a function described below.

a) ID data generating means 113a
The ID data generation unit 113a in FIG. 6 acquires the CPU-ID (identification code) uniquely assigned to the main CPU 61 at the timing of each interrupt processing of the CPU 61, and acquires it by adding the start bit and the end bit. ID data 120 (see FIG. 13) indicating the CPU-ID thus generated is generated in the form of serial data for transmission.

b) Log data generation means 113b
The log data generation unit 113b in FIG. 6 generates log data 121 (see FIG. 14) including game information, which is information related to the game controlled by the main CPU 61, every time one game (game) ends. Generate with Here, “1 game” is set as the first period as an aggregation criterion in the present invention. Note that the log data 121 shown in FIG. 14 includes various data described in detail below.

CPU-ID data CPU-ID data is data indicating an identification code uniquely assigned to the main CPU 61. If there is no injustice such as replacement of the main CPU 61 or attachment of a hanging board, the log is recorded. The CPU-ID indicated by the CPU-ID data stored in the data 121 indicates the same CPU-ID as the CPU-ID indicated by the ID data 120 in FIG. As with the ID data 120 described above, the ID data generation unit 113a acquires the CPU-ID of the CPU 61 every time the log data 121 is generated, and configures the CPU-ID data based on the acquired CPU-ID. To do.

Game state data The game state data (second information) is data indicating the game state set by the game state setting means 100b of FIG. As shown in FIG. 15A, for example, the game state data is composed of 1-byte data in which a game state is assigned to each bit. In this case, the current gaming state can be indicated by setting the bit corresponding to the current gaming state to ON “1” and setting the other bits to OFF “0”. Further, as shown in FIG. 15B, the game state data may be configured by 1-byte data in which a unique number is assigned to each game state and a number indicating the current game state is stored.

Payout number data The payout number data (first information) is data indicating the number of medals paid out by the payout control means 109 of FIG. For example, as shown in FIG. 16, the payout number data is configured by storing a number indicating the payout number in 4 bits (bit0 to bit3) of 1-byte data. In the present embodiment, when the re-game player is won, the payout number data is configured as three medals being paid out, but the payout number data is set as 0 medals being paid out. May be configured.

-Inserted-number data The paid-out number data is data indicating the number of inserted medals inserted into the slot machine 1 for playing a game. For example, as shown in FIG. 16, the number-of-insertions data is configured by storing a number indicating the number of insertions in 2 bits (bit4, bit5) of 1-byte data. In this embodiment, when the re-game player is won in the previous game, the inserted number data is configured as three medals inserted, but the number of inserted medals is set to 0. Data may be configured.

-Re-game data The re-game data is data indicating whether or not the current game is replay (re-game player). For example, as shown in FIG. 16, the replay data is composed of 1 bit (bit 7) of 1-byte data. In this case, it is possible to indicate whether or not the replay is performed by setting bit 7 to ON “1” when replaying and setting bit 7 to OFF “0” when not replaying.

・ Set value data
The set value data is data indicating the set value set by the setting control unit 101 in FIG. For example, as shown in FIG. 17, the set value data is configured by storing a number indicating a set value in 3 bits (bit 0 to bit 2) of 1-byte data.

Setting Change Data The setting change data is data indicating whether or not the setting value has been changed by the setting control unit 101 in FIG. 6 from the time when the previous log data 121 is generated until the present time. The setting change data is configured by 1 bit (bit 3) of 1-byte data, for example, as shown in FIG. In this case, the setting value is changed by setting bit 3 to ON “1” when the setting value is changed by the setting control unit 101, and setting bit 3 to OFF “0” in other cases. It can be shown whether it was done.

Door opening / closing data The door opening / closing data indicates whether or not the door opening / closing detection means 112 in FIG. 6 has detected that the front door 5 has been opened between the time when the previous log data 121 was generated and the present time. It is the data shown. The door opening / closing data is composed of 1 bit (bit 4) of 1-byte data, for example, as shown in FIG. In this case, bit 4 is set to ON “1” when the door opening / closing detection means 112 detects that the front door 5 has been opened, and bit 4 is set to OFF “0” in other cases. This can indicate whether or not the front door 5 has been opened. In this embodiment, it is detected by the door opening / closing detection means 112 that the front door 5 has been opened, but if the set value has been changed at the same timing, the bit 3 constituting the setting change data is turned on. It is configured to set “1” and to set bit 4 constituting the door opening / closing data to OFF “0”.

  As shown in FIG. 17, the remaining 3 bits (bit 5 to bit 7) constituting the illegal information flag data among the 1 byte constituting the set value data, the setting change data, and the door opening / closing data are OFF “0”. Log data 121 is generated.

c) Data transmission means 113c
The data transmission unit 113 c transmits the ID data 120 generated by the ID data generation unit 113 a toward the outgoing ball management board 83 at every interrupt processing timing of the main CPU 61 in FIG. 3. In addition, the data transmission unit 113 c transmits the log data 121 generated by the log data generation unit 113 b toward the output management board 83 at every timing when one game (game) is completed.

  In the log data 121 described above, the number of times the front door 5 is opened and closed between the time when the log data 121 related to the previous game is transmitted and the time when the current log data 121 is transmitted. Although the number of times the set value has been changed is not recorded, data indicating the number of times of opening / closing and the number of setting changes may be stored in the log data. In addition, every time the open / close state or set value of the front door 5 changes, data indicating these state changes may be separately generated and transmitted to the outgoing ball management board 83. In this case, in the game management board 83 described later, these states are stored in a storage area different from the log data storage area 853 (see FIG. 7) in which the log data 130 (log data 121) in FIG. 18 is stored. Data indicating a change may be stored.

(Sub control board)
Next, the configuration of the sub control board 73 will be described in detail. The sub CPU 71 of the sub control board 73 is for receiving a command transmitted from the main control board 63 and performing effects according to the operation and state of the main control board 63 (main CPU 61). As shown in FIG. 5, the sub-control board 73 is equipped with various functions realized by executing a program stored in the memory 75 and various functions realized by controlling hardware. Has been.

(1) Sub-control command receiving means 200
The sub-control command receiving unit 200 in FIG. 6 receives commands including various data transmitted by the sub-control command transmitting unit 110 of the main control board 63 as predetermined information. The sub control command receiving means 200 receives a command transmitted from the main control board 63 and, when receiving the command, notifies each function mounted on the sub control board 73 according to the type of the command.

(2) Production content determination means 201
The effect content determination unit 201 in FIG. 6 is for determining the content of the effect according to the command received by the sub-control command receiving unit 200. Specifically, a moving image to be displayed on the liquid crystal display 27 is determined from an effect pattern set in advance corresponding to the progress of the game, the result of the role lottery means 103, or the like from the speakers 31L and 31R. An effect such as determining the music and sound to be played, and flashing the light sources of the upper lamp unit 33 and the lower lamp units 37L and 37R all at once or individually is determined.

  If the received command corresponds to the AT period and the type of the winning combination group (bell group, replay) can be identified, the effect content determination unit 201 corresponds to the type of the winning group. A notification effect that allows the player to know an operation mode that is advantageous to the player is executed, and if the received command does not correspond during the AT period, the content of the effect is determined so as to execute an effect that does not reveal the operation mode that is advantageous to the player. For example, if the “No. 1” command shown in FIG. 11 is received according to the result of lottery, it is not during the AT period, so it is understood that one of the winning groups of “Bell Group” has been won. Select one production from a group of productions that do not know whether "Left bell", "Middle bell", or "Right bell" was won. In addition, when the “No. 2” command shown in FIG. 11 is received, one of the effects indicating that “Left Bell” has been won or the effect of prompting the user to operate the left stop switch 21L first is selected. Select. When the “No. 3” and “No. 4” commands shown in FIG. 11 are received, the effect contents are determined in the same manner.

  In addition, when the “No. 9” command shown in FIG. 12 is received, since it is not during the AT period, the winning group of any one of “Replay A”, “Replay B”, “Replay C”, and “Replay D” is won. Although it is understood that one of the “Replay A”, “Replay B”, “Replay C”, and “Replay D” is won, one effect is selected. In addition, when the “No. 10” command shown in FIG. 12 is received, one of the effects that indicates that “Replay A” has been won or the effect that prompts the user to operate the left stop switch 21L first is selected. Select. When the “11”, “12”, and “13” commands shown in FIG. 12 are received, the contents of the effect are similarly determined.

  Furthermore, when the contents-deciding means 201 receives the commands “No. 5” to “No. 8” shown in FIG. 11, the effect contents determining means 201 is similarly selected from the group of effects suggesting the possibility of winning each winning role group. Select the production. Further, when the “0” command is received, similarly, one effect is selected from the effect group corresponding to the loss so as not to impair the player's expectation.

  For example, the operation content of the stop switches 21L, 21M, and 21R is displayed on the liquid crystal display 27, and the operation order of the stop switches 21L, 21M, and 21R is notified by sound through the speakers 31L and 31R. The lamps provided on the stop switches 21L, 21M, and 21R are blinked in a predetermined order to notify the operation order of the stop switches 21L, 21M, and 21R, and the backs provided on the reels 13L, 13M, and 13R. There are effects such as blinking the lights in a predetermined order and notifying the operation order of the stop switches 21L, 21M, and 21R.

  Then, the effect content determination unit 201 transmits a signal including data regarding the determined effect content to the display control unit 202 and the audio control unit 203 described below.

(3) Display control means 202
The display control unit 202 in FIG. 6 displays a moving image on the liquid crystal display 27 based on the data included in the signal transmitted from the effect content determination unit 201, and displays the upper lamp unit 33 and the lower lamp units 37L and 37R. Perform effects such as flashing light sources all at once or individually.

(4) Voice control means 203
The voice control unit 203 in FIG. 6 executes effects such as playing music from the speakers 31L and 31R and outputting sound based on the data included in the signal transmitted from the effect content determination unit 201.

(Department management board)
Next, the ball management board 83 will be described in detail with reference to FIG. The payout management board 83 receives the ID data 120 and the log data 121 transmitted from the main control board 63, and manages the game state such as the payout rate. 7 is implemented by executing programs such as an ID comparison program 871 (see FIG. 3) and a log collection program 872 (see FIG. 3) stored in the ROM 87. And various functions realized by controlling the hardware.

(1) Data receiving means 300
The data receiving means 300 in FIG. 7 receives the ID data 120 transmitted by the outgoing ball management data transmitting means 113 (see FIG. 6) of the main control board 63 as an identification code, and uses the log data 121 as game information. Receive. The data receiving means 300 receives the ID data 120 at every interrupt processing timing of the CPU 61 where the ID data 120 is generated by the ID data generating means 113a of FIG. 6, and the log data generating means 113b of FIG. The log data 121 is received at each timing when one game (game) in which the data 121 is generated is completed.

(2) ID error determination means 301
The ID error determination unit 301 in FIG. 7 receives the regular CPU-ID of the main CPU 61 stored in the CPU-ID storage area 851 of the RWM 85 and the received ID every time the data reception unit 300 receives the ID data 120. The CPU-ID indicated by the data 120 is checked, and if both CPU-IDs are different from each other, it is determined that the received ID data 120 is an error. Further, each time the data receiving unit 300 receives the log data 121, the ID error determining unit 301 receives the normal CPU-ID of the main CPU 61 stored in the CPU-ID storage area 851 of the RWM 85 and the received log. If the CPU-ID indicated by the CPU-ID data constituting the data for data 121 is collated and the two CPU-IDs are different from each other, the received log data 121 corresponds to “error 1” shown in FIG. judge.

  Specifically, since the CPU-ID is an identification code uniquely assigned to the main CPU 61, the received ID data 120 is received if there is an irregularity such as replacement of the main CPU 61 or attachment of a hanging board. And the CPU-ID indicated by the CPU-ID data stored in the received log data 121 are different from those of the regular main CPU 61. Therefore, the CPU-ID indicated by the received ID data 120, the CPU-ID indicated by the CPU-ID data stored in the received log data 121, and the normality of the main CPU 61 stored in the CPU-ID storage area 851. By comparing with the CPU-ID, it can be determined whether there is a possibility that some fraud is being performed.

  In the present embodiment, when the slot machine 1 is shipped from the factory or when the power is turned on for the first time in the hall, the regular CPU-ID of the main CPU 61 is configured by an area preset in the RWM 85 of the output management board 83. It is stored in the CPU-ID storage area 851.

(3) Game number counter updating means 302
The game number counter updating unit 302 in FIG. 7 updates the count value of the game number counter 852 in the RWM 85 every time the data receiving unit 300 receives the log data 121. The game number counter 852 is configured in a preset area of the RWM 85 and stores the number of games (games). If the game number counter 852 is configured with a storage capacity of, for example, 2 bytes, the game number counter 852 can count up to 0-65535 games, but the count value is updated from 0-65535. After that, the number of games may be counted again from 0 to 65535.

(4) Date and time information acquisition means 303
The date / time information acquisition unit 303 in FIG. 7 measures the date and time when the data reception unit 300 received the log data 121 by acquiring the date / time data from the RTC 89 of the game management board 83 shown in FIG.

(5) Data error determination means 304
The data error determination unit 304 in FIG. 7 checks the contents of the received log data 121 every time the data reception unit 300 receives the log data 121. Specifically, the data error determination unit 304, based on the date and time counted by the date / time information acquisition unit 303, receives the log data 121 related to the previous game and the log data 121 related to the current game. When the time difference (reception interval) between the two times is shorter than a predetermined value set in advance, it is determined that the received log data 121 corresponds to “error 2” shown in FIG. .

  Specifically, even if the log data 130 including game information such as the number of payouts and the number of throws in when the fraud is performed is stored in the log data storage area 853 of the RWM 85, these log data 130 are stored in the log data storage area 853. For example, during the game during the business hours of the hall or outside the business hours of the hall, the log data 130 including the illegally generated game information is rewritten so that it is determined as normal data even if it is inspected later. In this case, it is impossible to determine whether or not fraud has been performed even if the log data that has been illegally rewritten later is viewed. For example, a hanging board for sending unauthorized log data is connected to the outgoing management board 83, and a large amount of unauthorized log data having a data amount exceeding the storage capacity of the log data storage area 853 of the RWM 85 is continuously produced in a short time. Therefore, the log data 130 stored in the log data storage area 853 is overwritten, and the normal log data 130 is rewritten with illegally generated log data.

  By the way, in the slot machine 1, the time spent for inserting medals for each game, the time from the start of rotation of each rotary reel 13L, 13M, 13R until the operation of each stop switch 21L, 21M, 21R becomes effective, Since it takes time to pay out medals, it takes at least 4.1 seconds to finish one game. However, when the log data 130 is illegally rewritten as described above, the storage (reception) interval of the log data 130 is shortened. Therefore, as shown in FIG. 22A, when the reception interval of the log data 121 is longer than 4.1 seconds, the data error determination unit 304 determines that the reception interval of the log data 121 is normal. judge. On the other hand, when the reception interval of the log data 121 is shorter than 4.1 seconds, the data error determination unit 304 determines that the reception interval of the log data 121 is an error.

  Note that, as shown in FIG. 22B, in the ball-type game machine, the log data reception interval can be checked in the same manner as in the slot machine 1. For example, if the log data 121 is generated every time when 10 game balls are fired (first period), it takes about 6.0 seconds to fire 10 game balls. is there. Therefore, as shown in FIG. 22B, when the reception interval of the log data 121 is longer than 6.0 seconds, it can be determined that the reception interval of the log data 121 is normal. On the other hand, as shown in FIG. 22B, when the reception interval of the log data 121 is shorter than 6.0 seconds, it can be determined that the reception interval of the log data 121 is an error.

  The data error determination unit 304 determines whether the reception interval of the log data 121 is normal based on the date / time data of the RTC 89, but the method of determining the reception interval is limited to this method. It is not something. For example, the data error determination unit 304 determines how many times the interrupt processing of the management CPU 81 has been executed from the timing when the log data 121 related to the previous game is received to the timing when the log data 121 related to the current game is received. It is possible to determine whether or not the reception interval of the log data 121 is an error. For example, if the log data 121 is received twice or more before the interruption processing of the management CPU 81 is executed a preset number of times, it may be determined that there is an error. Further, when the time indicated by the date / time data of the RTC 89 is outside business hours, an error may be determined.

  In addition, the data error determination unit 304 changes the logical value of the clock signal of the management CPU 81 from the time when the log data 121 related to the previous game is received to the time when the log data 121 related to the current game is received. It is also possible to determine whether or not the reception interval of the log data 121 is an error by counting whether or not the error has occurred. For example, if the log data 121 is received twice or more before the count value obtained by counting the number of times the logical value of the clock signal of the management CPU 81 has changed to a preset count value, it is determined that an error has occurred. You can do it. In addition, the data error determination unit 304 can obtain information with higher reliability by combining the respective information obtained from the interrupt signal and clock signal of the RTC 89 and the management CPU 81. For example, the reception interval of the log data 121 based on the date / time data of the RTC 89 is compared with the reception interval of the log data 121 based on the clock signal of the management CPU 81, and if there is a difference between them, the RTC 89 or the management CPU 81 The possibility of unauthorized access from outside can be found.

  Further, the data error determination unit 304 includes a part of each data constituting the log data 121 including an error value, that is, defective data having an impossible data value, or fails in reception. Thus, if the log data 121 includes defect data that does not make sense as data, it is determined that the received log data 121 corresponds to “error 3” shown in FIG. Specifically, for example, as shown in FIG. 17, the set value data is composed of 3-bit (bit 0 to bit 2) data, but the set value is set from “1” to “6”. When “000” indicating “0” is stored as setting value data or “111” indicating “7” is stored, it is determined that the log data 121 corresponds to “error 3” including defect data. Is done. Further, for example, as shown in FIG. 15A, out of 1-byte data indicating the gaming state, a special game (BB game (BB ′), RB game (RB ′)) and special role internal game (BB internal) A bit indicating a gaming state of one of a game (RT2) and an RB internal game (RT3), and a bit indicating a gaming state of either an AT game (AT1) or a special AT game (AT2) Since the game combination is not executed at the same time when ON “1” is set at the same time, it is determined that the log data 121 corresponds to “error 3” including defect data.

(6) Log data generation means 305
As shown in FIG. 18, the log data generation unit 305 in FIG. 7 adds date data and time data to the log data 121 received by the data reception unit 300 based on the date data acquired by the date information acquisition unit 303. By combining the game number data based on the count value of the game number counter 852 and combining the incorrect information flag data based on the determination results of the ID error determination means 301 and the data error determination means 304, one game ( Log data 130 (game information) as shown in FIG. 18 is generated every first period). Each of the date data and the time data is composed of, for example, 2-byte data.

  Further, for example, as shown in FIG. 17, the unauthorized information flag data constituting the log data 130 includes 3 bits (1 bit constituting the set value data, setting change data, and door opening / closing data of the log data 121 ( bit5 to bit7) can be configured by assigning the above-mentioned "Error 1", "Error 2", and "Error 3". In this case, as described above, the log data 121 received by the ID error determination unit 301 and the data error determination unit 304 is any one of “error 1”, “error 2”, and “error 3”. When the determination is made, the error type of the log data 121 can be indicated by setting the bit corresponding to the error type to ON “1”.

(7) Log data storage means 306
The log data storage unit 306 in FIG. 7 stores the log data 130 (see FIG. 18) generated by the log data generation unit 305 in a log data storage area 853 configured in a predetermined area of the RWM 85. At this time, as shown in FIG. 19, the log data storage means 306 stores the log data 130 in the log data storage area 853 for each game (G). By storing a plurality of log data 130 for each game (first period) in the log data storage area 853, a second period (eg, 6000 games) that is a longer totaling standard than the first period is stored. The log data 130 in the game can be specified (checked) after the fact.

  When the number of games played in the slot machine 1 is 6000 games to 10000 games per day, log data 130 for 6000 games to 10000 games per day can be stored for a period of about one year. The storage capacity of the log data storage means 306 is set. In addition, the log data storage unit 306 is configured as a ring buffer, and after the log data 130 is stored in the entire storage area of the log data storage unit 306, the log data storage unit 306 is sequentially overwritten from the oldest log data 130. Has been.

  A specific example of the log data 130 will be described with reference to FIGS. In the log data 130 shown in FIGS. 20 and 21, date data, time data, game number data, and CPU-ID are not shown.

  The log data 130 shown in FIG. 20 includes game state data indicating that the general game (RT1) is in a game state executed independently, payout number data indicating payout of 10 medals, and insertion of 3 medals. The inserted number data shown, the replay data indicating that it is not replay (replay), the set value data indicating that the set value is “1”, the setting change data indicating that the set value has been changed, and the front door 5 The door opening / closing data indicating that it is not opened, and the fraud information flag data indicating that there is no error in the log data 121.

  The log data 130 shown in FIG. 21 includes game state data indicating ART game (RT4 + AT1), payout number data indicating payout of 3 medals, insert number data indicating insertion of 3 medals, replay (replay). Re-game data indicating that the game is a game), setting value data indicating that the setting value is “1”, setting change data indicating that the setting value has not been changed, and indicating that the front door 5 has been opened. The door opening / closing data and log data 121 are constituted by unauthorized information flag data indicating that there is no error.

(8) Error processing means 307
The error processing means 307 in FIG. 7 executes at least one of the specifying processes 2 shown in FIG. 23 when the ID error determination means 301 determines that the received ID data 120 has an error. Further, the error processing unit 307 determines that the received log data 121 corresponds to one of “error 1”, “error 2”, and “error 3” by the ID error determination unit 301 or the data error determination unit 304. That is, data (flag) indicating that the received log data 121 corresponds to one of “error 1”, “error 2”, and “error 3” is stored in the invalid information flag data of the log data 130 shown in FIG. If so, at least one of the specific processes 1 shown in FIG. 23 is executed.

  Next, the specific process will be described in detail with reference to FIG.

(A) Cancel log data storage (Drop log data)
The error processing unit 307 discards the log data 130 generated based on the log data 121 corresponding to any one of “error 1”, “error 2”, and “error 3” without saving. In this way, it is possible to prevent the regular log data 130 stored in the RWM 85 from being rewritten with unauthorized log data 130.

(B) The log data storage destination is changed to the error log data storage area The error processing means 307 is generated based on the log data 121 corresponding to any one of “error 1”, “error 2”, and “error 3”. The stored log data 130 is stored in an error log data storage area 854 configured in a storage area different from the log data storage area 853 of the RWM 85, as shown in FIG. Note that a storage area for storing the log data 130 in an error state may be further provided. For example, the log data 130 in an error state may be stored in a storage area that is different for each error type. In this way, it is possible to prevent the regular log data 130 stored in the RWM 85 from being rewritten to the unauthorized log data 130 and to store details of the unauthorized log data 130.

(C) Stopping the power supply to the main control board The error processing unit 307 turns off the power supply switch 91 shown in FIG. 3 when the ID error determination unit 301 or the data error determination unit 304 determines that there is an error. By switching to, power supply to the main control board 63 is stopped. In this way, it is possible to prevent the player from playing a game in an unauthorized state.

(D) Stopping power supply to the sub control board The error processing means 307 turns off the power supply switch 91 shown in FIG. 3 when the ID error determination means 301 or the data error determination means 304 determines that there is an error. By switching to, power supply to the sub control board 73 is stopped. In this case, an image is not displayed on the liquid crystal display 27, the upper lamp unit 33 and the lower lamp units 37L and 37R are not lit, and no sound is output from the speakers 31L and 31R. The hall manager can be surely recognized that it is in a state.

(E) Send an error detection signal to the main control board (game stop, etc.)
The error processing unit 307 transmits an error detection signal (abnormality detection signal) to the main control board 63 as shown in FIG. 3 when the ID error determination unit 301 or the data error determination unit 304 determines that there is an error. To do. The game control means 100 (see FIG. 6) of the main control board 63 may stop the game or notify the outside when receiving the error detection signal. In this way, it is possible to prevent the player from playing a game in an unauthorized state, or to ensure that the hall manager recognizes the unauthorized state.

(F) External notification The error processing means 307 detects an error by switching the lighting state of the monitor LED 59 shown in FIG. 3 when the ID error determination means 301 or the data error determination means 304 determines that there is an error. External notification. At this time, the type of error may be determined by switching the lighting state of the monitor LED 59. If it does in this way, a hall manager can recognize certainly that it is an injustice state.

  In the present embodiment, when the ID error determination unit 301 or the data error determination unit 304 determines that there is an error, the error processing unit 307 is configured to execute one of the specific processes shown in FIG. However, for example, an error counter is provided that counts the number of times that an error is determined by the ID error determination unit 301 or the data error determination unit 304, and error processing is performed when the number of error counters exceeds a predetermined number. The means 307 may execute the specific process. Further, when the ID error determination unit 301 or the data error determination unit 304 determines that there is an error continuously for a predetermined number of games, the error processing unit 307 may execute the specific process. A plurality of specific processes may be executed in combination.

(9) Payout rate deriving means 308
As shown in FIG. 24, the payout rate deriving means 308 (derivation means) in FIG. 7 is based on the log data 130 for 6000 games (second period) that do not include errors, The number of payouts / the number of medals inserted (%)) is derived. That is, the payout rate in the second period is derived by calculating the total number of medals paid out in the second period and the total number of medals inserted in the second period. Further, the payout rate deriving means 308 calculates the number of medals paid out and the number of inserted medals for each gaming state in the second period (6000 games), and for each gaming state in the second period. The medal payout rate is derived. In the example illustrated in FIG. 24, only normal log data 130 that does not include an error is targeted for aggregation. However, log data 130 that includes an error may be included in the aggregation target.

(10) Stay ratio calculation means 309
The stay ratio calculation means 309 (calculation means) in FIG. 7 calculates the stay ratio of the gaming state in the second period (6000 games) in the present invention, as shown in FIGS. 25 (a) and 25 (b).

(11) Abnormal state determination means 310
As shown in FIG. 24, the abnormal state determination unit 310 in FIG. 7 has an upper limit value (here, a payout rate (%) in the second period (6000 games) derived by the payout rate deriving unit 308). Based on the rules, for example, it is determined whether it exceeds 150%). Then, on condition that the payout rate exceeds the upper limit value, the abnormal state determination means 310 determines the stay ratio in the second period derived by the stay ratio calculation means 309 and the determination criteria (slot machine 1) shown in FIG. Based on the design value), it is determined whether there is an abnormality in the stay ratio of each gaming state and the payout rate with respect to the stay ratio of each gaming state.

  That is, for example, in the example shown in FIG. 25A, the stay ratio in the second period of the ART game (RT4 + AT1) exceeds the upper limit value of the stay ratio considering the variation of the design value. It is determined that the stay ratio of the ART game (RT4 + AT1) is abnormal. From this determination result, in this case, it can be determined that there is a possibility of fraud, and there is a possibility that there is an abnormality in the main control board 63 because the stay ratio is not as designed. It can be determined that there is.

  On the other hand, in the example shown in FIG. 25 (b), there is no problem in the stay ratio of each gaming state, but the payout rate in the general gaming state RT1 exceeds the upper limit of the payout rate for each gaming state considering the variation of the design value. The abnormal state determination means 310 determines that there is an abnormality in the payout rate in the general game (RT1). From this determination result, in this case, it is possible to determine that there is a possibility that an illegal act that makes it possible to recognize the winning of the specific set win by an illegal act is not an AT.

  In the above-described example, the abnormal state determination unit 310 determines that the game is abnormal when the payout rate in the second period (6000 games) exceeds the upper limit value, and then determines the cause of the abnormality in detail for each game. State stay ratio and payout rate for each game state stay ratio exceed the upper limit set based on the design value respectively, but it is determined as abnormal, but the lower limit set based on the design value Even if it does not reach, it may be determined as abnormal. For example, the ratio of the payout number in the second period of the special role game (BB game BB ′, RB game RB ′) to the total payout number in all game states in the second period is an upper limit value (for example, 7 to 80%) and when the lower limit is not reached (for example, 20-30%), specifically, if there are 10,000 payouts in the second period, the number of bonus payouts However, when the number is 7,000 to 8,000 or more or 2,000 to 3,000 or less, the abnormal state determination unit 310 may determine that there is an abnormality. In this case, even when the payout rate for the entire second period does not exceed the preset upper limit value, it may be determined to be abnormal.

  Further, the payout rate and the stay ratio may be determined to be abnormal by setting an abnormal level in stages according to the degree of abnormality. That is, when it is determined as abnormal in the total result of the game in the second period of the first time, it is determined that the “warning level” is abnormal, and continuously abnormal in the total result of the game in the second period after the second time. May be determined as an abnormal “warning level”. Further, when the payout rate and the stay ratio exceed the upper limit of the first stage or do not reach the lower limit of the first stage, it is determined that the “warning level” is abnormal, and the payout ratio and the stay ratio are When the upper limit value of the second stage that is larger than the upper limit value of the first stage is exceeded or the lower limit value of the second stage that is smaller than the lower limit value of the first stage is not reached, it is determined that the “warning level” is abnormal. It may be. Note that the abnormality notification determination may include a payout rate and a payout number.

  Further, as shown in FIG. 26, a general AT game (RT1 + AT1 (ART game preparation game)), a general special AT game (RT1 + AT2), a BB internal game (RT2), an RB internal game (RT3), a single RT game (RT4) Since the stay ratio of (general game standby game)) is extremely small, in FIG. 25 (a) and (b), they are collectively described as “others”.

(12) History abnormality notification means 311
The history abnormality notifying means 311 in FIG. 7 notifies the outside when the abnormal state determining means 310 determines that there is an abnormality in the payout rate or stay ratio. Specifically, the history abnormality notification means 311 performs external notification by switching the lighting state of the monitor LED 59 shown in FIG. Further, the history abnormality notification means 311 uses, for example, an abnormality notification instruction signal for instructing to perform notification using stage devices such as the upper lamp unit 33, the lower lamp units 37L and 37R, and the speakers 31L and 31R, as the main control board. The external notification may be performed by transmitting to 63 or the sub-control board 73.

  In addition, when the abnormal level is determined stepwise by the abnormal state determination unit 310, the history abnormality notification unit 311 may change the notification content according to the abnormal level. Further, the notification contents may be different based on the determination result by the abnormal state determination means 309. By configuring in this way, based on the notification content, the administrator, the player, the person in charge of the inspection may have an abnormality, and the type of abnormality that may have occurred Can be recognized.

(13) Data input / output means 312
The data input / output means 312 in FIG. 7 communicates with the inspection device P (see FIG. 3) connected to the outgoing ball management board 83 via a dedicated interface, and the log data storage area 853 (error log data storage area 854). The log data 130 stored in () is input / output.

(Inspection equipment)
Next, the inspection apparatus P shown in FIG. 3 will be described.

  The inspection apparatus P has substantially the same functions as the payout rate deriving unit 308, the stay ratio calculating unit 309, the abnormal state determining unit 310, and the history abnormality notifying unit 311 shown in FIG. The log data 130 stored in the log data storage area 853 of the outgoing ball management board 83 can be received while being connected to the management board 83. The inspection apparatus P outputs a signal requesting transmission of the log data 130 to the data input / output unit 312 of the ball management board 83, and a predetermined signal transmitted by the data input / output unit 312 in response to the request signal. Log data 130 corresponding to the number of games is received. For example, based on the log data 130 for 6000 games (second period), the payout rate in the second period and the payout rate in each gaming state are derived, and the stay ratio of each gaming state in the second period is calculated. Calculate to determine whether there is an abnormality in the payout rate and stay ratio.

  In the present embodiment, the slot machine 1 is configured to aggregate the log data 130 for a predetermined number of games and determine (check) whether there is an abnormality in the payout rate or the stay ratio. The slot machine 1 is not equipped with such a check function for the log data 130, but only the function for storing the log data 130 is installed in the slot machine 1, and the payout rate and stay ratio are adjusted by an external device such as the inspection device P after the fact You may make it determine whether there exists abnormality.

(Operation)
Next, the operation of the slot machine 1 will be described with reference to FIGS. In the present embodiment, any one of the winning role groups “left bell”, “middle bell”, “right bell”, “replay A”, “replay B”, and “replay C” is performed during the AT period (the AT period flag is ON). When winning, the effect of notifying the operation order of each stop switch 21L, 21M, 21R that is advantageous to the player corresponding to the winning winning group is the notification means 111 and the sub control board 73 of the main control board 63. This is executed by the display control means 202 and the voice control means 203.

  In the following description, the various functions and means described above, and other functions realized by executing various programs by the main CPU 61 of the main control board 63 and the sub CPU 71 of the sub control board 73 (detailed explanation is omitted). This is a process executed by. In addition, since processing for setting various flags executed in the following processing to ON or OFF or setting values for various flags is a well-known technique, detailed description thereof is omitted.

1. Main Processing With reference to FIG. 27, main processing executed in the main CPU 61 of the main control board 63 will be described.

  When the power of the slot machine 1 is turned on, the state of the RWM 65 provided in the main control board 63 is checked, it is determined whether an error has occurred in the memory, various initial settings are performed, and the results of the RWM 65 check If there is no abnormality, control is performed so that a game is possible. When the power is turned on with a setting change, the game shifts to a general game (RT1). Moreover, when returning from the power OFF state at the time of a power failure to the power ON state, the game state before the power failure may be restored. Next, as shown in FIG. 27, it is determined whether or not a prescribed number (three) of medals have been inserted (step S1), and the system waits until a prescribed number of medals are inserted (NO in step S1). On the other hand, if a predetermined number (three) of medals are inserted (YES in step S1), the process waits until the start switch 19 is operated (NO in step S2), and if the start switch 19 is operated (step S2). YES), the part lottery process by the part lottery means 103 is executed (step S3).

  In the role lottery process of the role lottery means 103, first, the table lottery table 671 is selected by the table selection means 102 based on the current gaming state and the selected role lottery table 671 and the start switch 19 are operated. The winning lottery result is determined based on the random value extracted at the timing.

  Then, after the winning lottery process, as shown in FIG. 27, rotation of each reel 13L, 13M, 13R is started (step S4), and each stop switch 21L, corresponding to each reel 13L, 13M, 13R that is rotating. Wait until any one of 21M and 21R is operated (NO in step S5). If any one of the stop switches 21L, 21M and 21R is operated (YES in step S5), the reel rotation by the stop control means 107 is performed. The stop rotation of the reel corresponding to the operated stop switch is stopped (step S6).

  Thereafter, the processes in steps S5 and S6 are repeatedly executed until the rotation of all the reels 13L, 13M, and 13R is stopped (NO in step S7), and if all the reels 13L, 13M, and 13R are stopped ( In step S7, the symbol determination unit 108 determines the symbol (step S8).

  Subsequently, notification determination processing (step S9) is executed, and if the AT1 transition condition shown in FIG. 9 is satisfied, the state of the flag during the AT period stored in the flag storage unit 651 is turned ON by the notification determination unit 104. Set to When the game is played 50 times during the AT period (when there is no extra game), the AT period flag is set to OFF. On the other hand, if the AT1 transition condition is not satisfied, the notification determination process is terminated.

  As shown in FIG. 27, after the notification determination process, the payout control means 109 executes a medal payout process as necessary (step S10), and a data transmission process described with reference to FIG. Step S11) and the process from step S1 are repeatedly executed.

2. Data Transmission Processing Next, the data transmission processing in step S11 of FIG. 27 will be described with reference to FIG.

  First, the log data 121 shown in FIG. 14 is generated by the log data generation means 113b (step S20). Then, the generated log data 121 is transmitted to the outgoing ball management board 83 by the data transmission means 113c (step S21), and the process returns to the main process of FIG.

3. ID Data Transmission Processing Next, ID data transmission processing that is executed every time interrupt processing is performed in the main CPU 61 of the main control board 63 will be described with reference to FIG.

  First, the ID data 120 shown in FIG. 13 is generated by the ID data generating means 113a (step S30). Then, the generated ID data 120 is transmitted by the data transmission unit 113c to the outgoing ball management board 83 (step S31), and the process is terminated.

4). Gaming Machine Monitoring Process The gaming machine monitoring process executed by the management CPU 81 of the payout management board 83 will be described with reference to FIG.

  First, the ID data 120 or log data 121 transmitted from the main control board 63 is received by the data receiving means 300 (step S40). Next, it is determined whether or not the received data is the ID data 120 (step S41). If the received data is the ID data 120 (YES in step S41), an ID data determination process described with reference to FIG. 31 is executed. (Step S42). Next, when the ID data determination process in step S42 is completed, the process ends. When it is determined NO in step S41, the process proceeds to step S43, and whether the received data is the log data 121 or not. Determined.

  If it is the log data 121 (YES in step S43), a log data storage process described with reference to FIG. 32 is executed (step S44). Next, when the log data storage process of step S44 ends or when it is determined NO in step S43, the process proceeds to step S45, and the count value (game number) of the game number counter 852 is set to a set number (for example, 6000). It is determined whether or not the game is over. If the number of games is equal to or greater than the set number (YES in step S45), a payout history management process described with reference to FIG. 33 is executed (step S46), and the process ends. On the other hand, if NO is determined in the step S45, the process is ended.

5. ID Data Determination Process Next, the ID data determination process (step S42) in FIG. 30 will be described with reference to FIG.

  First, the CPU-ID indicated by the received ID data 120 is compared with the CPU-ID stored in the CPU-ID storage area 851 (step S50), and it is determined whether the CPU-IDs match or not. Determination is performed by the determination unit 301 (step S51). If both CPU-IDs match (YES in step S51), the process returns to the gaming machine monitoring process of FIG. 30, and if both CPU-IDs do not match (NO in step S51), the specific process 2 shown in FIG. This is executed by the error processing means 307 (step S52), and the process returns to the gaming machine monitoring process of FIG.

6). Log Data Storage Processing Next, the log data storage processing (step S44) in FIG. 30 will be described with reference to FIG.

  First, based on the received log data 121, log data 130 shown in FIG. 18 is generated by the log data generation means 305 (step S60). Next, the CPU-ID data included in the received log data 121 is compared with the CPU-ID stored in the CPU-ID storage area 851 (step S61), and whether or not both CPU-IDs match. Is determined by the ID error determination means 301 (step S62). If both CPU-IDs match (YES in step S62), the log data generating means 305 sets the bit corresponding to “error 1” in the log data 130 to “0” indicating OFF (step S63). If the CPU-IDs do not match (NO in step S62), the log data generating means 305 sets the bit corresponding to “error 1” in the log data 130 to “1” representing ON (step S64).

  Subsequently, the time when the log data 121 related to the previous game is received and the time when the log data 121 related to the current game is received are calculated by the data error determination unit 304 (step S65), and the time difference between the calculated times ( It is determined by the data error determination means 304 whether or not the (reception interval) is longer than a predetermined value (for example, 4.1 seconds) (step S66). If the reception interval is longer than the specified time (YES in step S66), the log data generation means 305 sets the bit corresponding to “error 2” in the log data 130 to “0” indicating OFF (step S67). If the reception interval is shorter than the specified time (NO in step S66), the log data generating means 305 sets the bit corresponding to “error 2” in the log data 130 to “1” indicating ON (step S68).

  Subsequently, the data error determination unit 304 determines whether or not the received log data 121 includes defect data (step S69). If defect data is not included (YES in step S69), the log data generation means 305 sets the bit corresponding to “error 3” in the log data 130 to “0” representing OFF (step S70), and the defect If data is included (NO in step S69), the bit corresponding to “error 3” in the log data 130 is set to “1” representing ON by the log data generation unit 305 (step S71).

  Next, the error processing means 307 determines whether any of “error 1”, “error 2”, and “error 3”, which are invalid information flags of the log data 130, is set to ON “1” (step S72). If YES is determined in the step S72, the specific process 1 shown in FIG. 23 is executed by the error processing means 307 (step S73), and the process returns to the gaming machine monitoring process of FIG. If NO is determined in step S72, the log data 130 generated by the log data generation unit 305 is stored in the log data storage area 853 by the log data storage unit 306 (step S74), and the gaming machine of FIG. Return to monitoring processing.

7. Roll-out history monitoring process Next, the roll-out history monitoring process in step S46 of FIG. 30 will be described with reference to FIG.

  First, the payout rate of medals in the second period (for example, 6000 games) is derived by the payout rate deriving unit 308 (step S80), and the stay ratio of each gaming state is calculated by the stay rate calculating unit 309 (step S81). . Subsequently, whether or not there is an abnormality in the payout rate and the stay ratio is determined by the abnormal state determination unit 310 (step S82). If YES is determined in step S82, the history abnormality notification unit 311 records the log data 130 history. Is informed that there is an abnormality (step S83). Then, if a history abnormality is notified in step S83 or if NO is determined in step S82, the process returns to the gaming machine monitoring process of FIG.

(Operation of inspection device P)
Subsequently, the operation of the counting process executed in the inspection apparatus P will be described with reference to FIG.

  First, the log data 130 is taken into the apparatus from the outgoing ball management board 83 (step S90). Then, the payout rate in the second period (for example, 6000 games) is derived (step S91), the stay ratio is calculated (step S92), and it is checked whether the payout rate and the stay ratio are abnormal ( Step S93) and the process is terminated.

  Therefore, according to the first embodiment described above, by reading and verifying the log data 130 stored in the RWM 85, it is possible to easily check in detail what kind of fraud has occurred at what timing. This is very effective as a countermeasure against fraud. At this time, since the ROM 87 is restricted to be unchangeable and cannot be written (additional writing, overwriting, etc.) or erased, game information management such as an ID comparison program 871 and a log collection program 872 from the outside. Unauthorized access to the program can be prevented, and unauthorized modification of the log data 130 stored in the RWM 85 can be prevented.

  The log data 130 includes not only data (information) that can specify the number of inserted medals and the number of paid out medals for deriving the payout rate, but also data that can specify the date and time when the log data 130 is generated, main data Data for specifying game information, such as data that can specify the CPU-ID of the CPU 61, data that can specify the gaming state of the slot machine 1, information about setting values of the slot machine 1, data about the open / closed state of the front door 5, It also includes fraud information flag data indicating whether the game information (data) is appropriate or abnormal, and derives a general medal payout rate. The stay ratio in the second period of the gaming state can also be calculated.

  Therefore, for example, when an abnormal payout rate is derived, the cause of the abnormal payout rate being derived can be examined in more detail, and appropriate measures can be taken according to the cause. Become. Therefore, when the payout rates of the plurality of different second periods are the same, the cause could not be examined in detail in the past, and thus it was not possible to take appropriate measures according to the cause. In the first embodiment, an optimum measure can be taken according to the situation of each second period.

  Further, by verifying the date data and time data of the log data 130 shown in FIG. 18, for example, the time of storage of the log data 130 related to the previous game and the time of storage of the log data 130 related to the current game are assumed. Whether the stored log data 130 has been illegally rewritten based on whether the stored log data 130 has been illegally rewritten or not. It is possible to easily check whether or not the illegal rewriting has been performed.

<Sixth Embodiment>
A sixth embodiment of the present invention will be described with reference to FIGS. The sixth embodiment is an example in which the gaming machine of the present invention is applied to a ball-type (pachinko) gaming machine, and the same configuration and operation as in the first embodiment will be described by quoting the same reference numerals. Shall be omitted.

  The ball-type game machine according to the present embodiment includes a start area, an electric accessory, an operating gate, and a special winning opening. Then, when the game ball passes through the starting area, a jackpot lottery for determining whether or not to shift to the jackpot gaming state is performed, and when the jackpot is won, the gaming state shifts to a jackpot state in which the jackpot game is executed To do. The electric accessory is for switching between a state in which the game ball is difficult to pass through the start region and a state in which the game ball is easy to pass through. The drive of the electric accessory makes it difficult for the game ball to pass through the start region. The game state is configured to switch between the state and the state where the game ball easily passes through the starting area. In addition, a switching lottery for determining whether or not to switch between a state in which the game ball does not easily pass through the start area and a state in which the game ball easily passes through the start area when the game ball has passed the operation gate When the selection is won, the electric accessory is driven and controlled, so that the game ball is not easily passed through and the game ball is easily passed.

  The jackpot probability that wins the jackpot by the jackpot lottery can be changed from a low probability to a high probability, and the switching probability that wins the switch by the switching lottery can be changed from a low probability to a high probability. Therefore, the ball-type game machine according to the present embodiment has at least a) a big hit state (a state where the player can win a big winning opening and is advantageous to the player), b) a general gaming state (a low jackpot probability and a switching probability) 4) gaming states of low probability), c) probability variation state (at least high probability of jackpot probability), and d) easy passage state (at least high probability of switching probability). Moreover, you may have the game state which is a probability fluctuation state and an easy passage state. In this specification and FIG. 41, FIG. 43, FIG. 44, and FIG. 45, it is a low probability state that the jackpot probability is low, a high probability state that the jackpot probability is high, and a low probability of switching. This state may be referred to as a low base state, and a state with a high switching probability may be referred to as a high base state.

  In addition, in the case of a ball-type game machine, the aggregation standard is expressed by the number of shot balls or game (play) time of the game ball (game value), unlike the aggregation standard set by the number of games in the slot machine 1 described above. Is done. In the present embodiment, the log data 131 (game information) shown in FIG. 40 is generated at every timing (first period) at which ten game balls are fired.

  As shown in FIG. 40, in the log data 131, data numbers sequentially assigned to the respective log data 131 generated every first period are stored instead of the above-mentioned number-of-games data of the slot machine 1. Further, in the log data 131, instead of the insertion number data and the payout number data of the slot machine 1 described above, the number-of-balls data indicating the number of the ten shots fired in the first period, The payout ball number data (first information) indicating the payout number in the period is stored.

  The log data 131 stores game state data (second information) shown in FIG. As shown in FIG. 41, the game state data is composed of 1-byte data in which the game state of the above-described ball-type game machine is assigned to each bit. In this case, the current gaming state can be indicated by setting the bit corresponding to the current gaming state to “1” representing ON and setting the other bits to “0” representing OFF.

  Further, as shown in FIG. 42, the log data 131 reproduced every first period stores the log data 131 generated every first period in the log data storage area 853 (see FIG. 7). As shown in FIG. 42, a plurality of log data 131 for each first period is stored in the log data storage area 853, so that a second period (for example, 600) that is a longer aggregation standard than the first period is stored. Log data 131 can be specified (checked) after the fact.

  A specific example of the log data 131 will be described with reference to FIGS. 43 and 44. In the log data 131 shown in FIGS. 43 and 44, the date data, time data, data number, and CPU-ID are not shown.

  The log data 131 shown in FIG. 43 includes game state data indicating a big hit state, payout ball number data indicating the payout of 112 pachinko balls, fire ball number data indicating the launch of 10 game balls, front door Is composed of door opening / closing data indicating that is not opened, and illegal information flag data indicating that there is no error in the log data.

  The log data 131 shown in FIG. 43 includes game state data indicating high probability state and high base state, payout ball number data indicating payout of 20 game balls, and fire ball indicating launch of 10 pachinko balls. It consists of numerical data, door opening / closing data indicating that the front door is not opened, and unauthorized information flag data indicating that there is no error in the log data.

  Next, an example of the payout rate will be described with reference to FIG.

  As shown in FIG. 45, a payout rate of game balls (number of payout balls / number of shot balls (%)) is derived based on 600 log data 131 (second period) that do not include an error. . That is, the payout rate in the second period is derived by calculating the total number of game balls paid out in the second period and the total number of game balls fired in the second period. At this time, in the ball-type game machine, when the criterion for determining whether or not the payout rate is abnormal is set to 300%, for example, the payout rate is 400% in the example shown in FIG. Therefore, it is determined that the payout rate is abnormal. Similarly to the slot machine, the number of game balls paid out in the second period and the number of game balls fired are calculated for each gaming state, and the game for each gaming state in the second period is calculated. A ball payout rate may be derived.

  As described above, according to the sixth embodiment, game information peculiar to the ball-type game machine included in the log data 131 can be easily checked like the slot machine.
