Description

  The present invention relates to a gaming machine that determines by lottery whether or not to give a game profit to a player.

  A slot machine as a gaming machine is provided with a plurality of gaming states and performance states that differ in the player's degree of advantage (game profit) as the game progresses. For example, there is a slot machine that adopts a specification in which a symbol combination corresponding to a bonus combination is displayed on an active line to shift from a normal gaming state to a bonus gaming state in which a player can easily acquire medals.

  However, if the frequency of transition to such a bonus game state is biased, there is a concern that the shooting performance will be excessively increased. Therefore, a technique for storing game information such as the number of inserted medals, the number of paid-out medals, and success / failure of a replay role and monitoring the history is known (for example, Patent Document 1).

  Here, the winning combination constituting the winning type extracted from the winning type lottery table includes a replay role, a small role, and a bonus role. Such a combination of symbols corresponding to the winning combination is referred to as a display or winning when the combination on the active line A is displayed. Until the winning combination including the winning combination is won and the symbol combination corresponding to the winning combination is displayed. Is the internal winning state. Among the winning combinations, the replay combination is a combination in which, when the symbol combination corresponding to the replay combination is displayed on the active line A, the player can execute one game again without making a new bet of medals by the player. The small combination is a combination that allows a predetermined number of medals to be paid out according to the symbol combination by displaying the symbol combination corresponding to the small combination on the active line A. Further, the bonus combination is a winning combination that can change the gaming state managed by the state transition means 312 to the bonus gaming state by displaying the symbol combination corresponding to the bonus combination on the active line A. .

  In this embodiment, as the winning combination, as shown in FIG. 5, the winning combination “normal replay”, “transition replay 1”, “transition replay 2”, “transition replay 3”, “transition replay 4”, “Migration Replay 5”, “Migration Replay 6”, “Migration Replay 7” (hereinafter, these eight replays may be simply abbreviated as “Replay”), “Maintenance Bell 1”, “Maintenance Bell 2”, “Maintenance Bell 3”, “Maintenance Bell 4”, “Maintenance Bell 5”, “Maintenance Bell 6”, “Maintenance Bell 7”, “Maintenance Bell 8”, “Maintenance Bell 9”, “Maintenance Bell 10”, “Maintenance Bell” “Bell 11”, “Maintenance Bell 12”, “Maintenance Bell 13”, “Maintenance Bell 14”, “Maintenance Bell 15”, “Maintenance Bell 16”, “Maintenance Bell 17”, “Maintenance Bell 18”, “Maintenance Bell 19” ”,“ Maintenance bell 20 ”,“ Maintenance bell 21 ”,“ Maintenance bell 2 ” ”,“ Maintenance Bell 23 ”,“ Maintenance Bell 24 ”,“ Increase Bell 1 ”,“ Increase Bell 2 ”(hereinafter,“ Maintenance Bell 1 ”to“ Maintenance Bell 24 ”,“ Increase Bell 1 ”,“ Increase ” The 26 bells of “Bell 2” are simply abbreviated as “Bell”, and the 24 winning roles “Maintenance Bell 1” to “Maintenance Bell 24” excluding “Increase Bell 1” and “Increase Bell 2” The bell may be simply abbreviated as “maintenance bell”, “cherry”, “RBB1”, “RBB2”, “RBB3”, “CBB” (hereinafter, “RBB1”, “RBB2”, “RBB3” ”And“ CBB ”may be simply abbreviated as winning combination“ BB ”). In FIG. 5, one or more symbols constituting each winning combination are associated with each of the rotating reels 134a, 134b, and 134c. Among these, the winning combination “Replay” corresponds to the replaying role, the winning roles “Bell” and “Cherry” correspond to the small role, and the winning combination “BB” corresponds to the bonus role.

(Replay role)
As a result of lottery, if a winning category that includes one of the winning roles `` Replay '' is won and operated in the operation mode (in this order of operation) as the winning conditions, the symbol combination corresponding to the winning role Among them, the symbols written on each of the rotating reels 134a, 134b, 134c can be displayed on the effective line A, and when the symbol combination corresponding to the winning combination is displayed on the effective line A, as described above. One game can be executed again without betting by the player.

  In the present embodiment, when the stop switch 130 is pressed by the player and the symbols constituting the symbol combination corresponding to the winning combination are on the active line A, the reel control means 306 Then, stop control is performed so that the symbol stops on the effective line A. In addition, when the stop switch 130 is pressed, there is no symbol constituting the symbol combination corresponding to the winning combination on the effective line A, but the direction opposite to the rotation direction of the rotary reels 134a, 134b, 134c. If it is within the range (drawing range) corresponding to the 4 symbols of the symbol, the reel control means 306 makes the number of symbols separated as the number of sliding symbols, and configures the symbol combination corresponding to the winning combination The stop control is performed so as to stop after maintaining the rotation by the number of sliding frames so as to draw the symbol to be drawn on the effective line A. In addition, when there are a plurality of symbols corresponding to the winning combination in each of the rotating reels 134a, 134b, 134c, and all of them are within the pull-in range of each of the rotating reels 134a, 134b, 134c, a predetermined priority is set. It is determined which symbol is to be drawn on the effective line A according to the rank, and stop control is performed so as to stop after maintaining the rotation by the number of sliding frames so as to draw the prioritized symbol on the effective line A. If the symbol constituting the symbol combination corresponding to the winning combination other than the selected winning combination is on the active line A when the stop switch 130 is pressed, the reel control means 306 selects the symbol. A so-called kicking process is also performed in parallel so as not to stop on the effective line A. Further, as will be described later, when the operation mode (operation order and operation timing) is set as a winning condition for the winning combination constituting the winning type, the reel control means 306 receives the winning according to the operation mode of the player. Stop control is performed so that the symbol combination corresponding to the combination can be displayed on the effective line A.

  In each of the rotating reels 134a, 134b, and 134c, the symbols constituting the symbol combination corresponding to the winning combination “normal replay” are arranged so as to be displayed on the effective line A by the stop control. (See FIGS. 3 and 5). Specifically, the symbols constituting the symbol combination corresponding to the winning combination “normal replay” are separated from each other only by a maximum of four symbols in each of the rotating reels 134a, 134b, 134c. A can be displayed on A. In this way, when a winning type including the winning combination “normal replay” is won and operated in the operation mode as a winning condition, the symbol combination corresponding to the winning combination “normal replay” is always an effective line. A will be displayed on A.

  As will be described in detail later, when the winning type including the winning combination “normal replay” is won, the stop control is performed depending on the winning mode (for example, whether the winning combination “normal replay” is won alone, It is set differently depending on the combination (for example, whether the winning combination “Migration Replay 1”) and the winning combination are duplicated. Therefore, according to the winning mode and the player's operating mode, the symbol combination corresponding to any winning combination of the winning combination “Replay” won in duplicate is displayed on the active line A.

(Small role)
In addition, as a result of the winning type lottery, if a winning type that includes one of the winning combinations “Bell” is won, each of the rotating reels 134a, 134b, and 134c is described in the symbol combination corresponding to the winning combination. When the symbol to be displayed can be displayed on the effective line A and the symbol combination corresponding to the winning combination “Bell” is displayed on the effective line A, the number of medals corresponding to each winning combination is paid out to the player. It is.

  In addition, the winning types including the winning roles “Maintenance Bell 1” to “Maintenance Bell 24” are won, and specific conditions (in the operation order associated with the winning roles “Maintenance Bell 1” to “Maintenance Bell 24”) are selected. When the operation) is satisfied, the symbol combinations corresponding to the winning combinations “maintenance bell 1” to “maintenance bell 24” are not necessarily displayed on the active line A.

  In addition, as will be described in detail later, in this embodiment, the winning combination “Increase Bell 1” and “Increase Bell 2” do not win independently, but other winning combinations (for example, the winning combination “Maintenance Bell 1”) ”To the winning combination (one or more winning combinations selected from“ maintenance bell 24 ”), and the winning control is set so that the stop control differs depending on the winning mode of the overlapping winning combination. Therefore, although the symbol combinations corresponding to the winning combination “Increase Bell 1” and “Increase Bell 2” are always arranged to be displayed on the active line A (see FIGS. 3 and 5), the winning combination “ Even if a winning type including “Increase Bell 1” and “Increase Bell 2” is won, depending on the operation mode, the player may miss it, and the player will win the “Increase Bell 1” and “Increase Bell 2”. It is not always possible to display the symbol combination corresponding to the above on the effective line A.

  In addition, as a result of the winning type lottery, if the winning type “Cherry” including the winning combination “Cherry” is won, the symbol combination corresponding to the winning combination “Cherry” can be displayed on the active line A. Here, “ANY” indicates that any symbol may be stopped on the corresponding effective line A. However, even if the winning type “Cherry” including the winning combination “Cherry” is won, so-called “missing” may occur, and the player does not necessarily place the symbol combination corresponding to the winning combination “Cherry” on the active line A. It is not always displayed.

(Bonus role)
Further, as a result of the winning type lottery, when the winning type including any of the winning combination “BB” is won, among the symbol combinations corresponding to the winning combination “BB”, each of the rotating reels 134a, 134b, 134c. The symbols written on each can be displayed on the effective line A. For example, when the winning type including the winning combination “RBB1” is won, it is recorded on each of the rotating reels 134a, 134b, 134c among the plurality of symbol combinations corresponding to the winning combination “RBB1” shown in FIG. The “BAR” symbol to be displayed can be displayed on the effective line A. When the symbol combination corresponding to the winning combination “RBB1” is displayed on the active line A, the bonus game flag is turned on, so that the game state is set to the bonus game state, and the next one game (hereinafter simply referred to as “game”). After that, the game can be executed in the bonus game state until a predetermined number of medals are paid out. In each of the rotating reels 134a, 134b, and 134c, the “BAR” symbol is arranged so that it may not be displayed on the effective line A even by the stop control described above (see FIGS. 3 and 5). ). Therefore, even if the winning type including the winning combination “RBB1” is won, the player is not necessarily displayed on the active line A with the symbol combination corresponding to the winning combination “RBB1”.

  Note that when any of the above-described winning types is won, internal winning flags corresponding to the respective winning types are established (turned on), and each of the rotating reels 134a, 134b, 134c is set according to the establishment status of the internal winning flag. The stop control is performed. At this time, if the winning combination including the small combination is won, but the symbol combination corresponding to the winning combination cannot be displayed on the active line A within the one game, After completion, the internal winning flag is turned off. In other words, the right to win a small role is limited to only one game won in the winning type including the small role, and the right cannot be carried over to the next game. On the other hand, when the winning type including the winning combination “BB” is won, the BB internal winning flag is established (turned on), and the symbol combination corresponding to the winning combination “BB” is on the active line A. Until it is displayed, the BB internal winning flag is carried over the game. When the internal winning flag corresponding to the winning type including the winning combination “replay” that is the replaying role is established, the symbol combination corresponding to the winning combination is always displayed on the active line A and requires a medal. After the processing necessary for performing the next game without being performed, the internal winning flag is turned off.

(Game state transition)
Here, the transition of the gaming state including the bonus gaming state will be described with reference to FIG. Here, a plurality of gaming states such as an RT1 gaming state, an RT2 gaming state, an RT3 gaming state, an RT4 gaming state (ART gaming state), an internal medium gaming state, and a bonus gaming state are prepared. The RT1 gaming state, the RT2 gaming state, the RT3 gaming state, and the RT4 gaming state are set with the winning probability of the replay role (RT1 gaming state = 1 / 7.3, RT2 gaming state = 1 / 7.3, RT3 gaming, respectively. State = 1 / 1.4, RT4 gaming state = 1 / 1.4), so-called RT gaming state, and as described later, mainly when a predetermined winning combination is displayed on the active line A, RT gaming State transitions. Here, the winning probability of the replaying role in the RT4 gaming state is set to be relatively high, and the player can advantageously advance the game by shifting to the RT4 gaming state. In the RT4 gaming state, it is assumed that an AT is performed in parallel, that is, so-called AT is performed in parallel (AT performance state). In the present embodiment, AT is performed in parallel with the RT4 gaming state. This state is called the ART gaming state.

  The state transition means 312 shifts the plurality of game states based on winning or winning of a predetermined winning type such as winning combination “Replay” or winning combination “BB”. Further, the state transition means 312 determines whether or not to shift the effect state from the non-AT effect state to the AT effect state based on the effect type determined by the effect type lottery. When the transition to the AT effect state is determined by the effect state lottery, the game state is changed to the RT4 game state, and the ART game state in which the AT effect state and the RT4 game state progress in parallel is executed. The The effect state will be described later in detail.

  Specifically, when the transition to the AT effect state is determined, if the game state is the RT1 game state, the auxiliary effect is performed, and the symbol combination indicating the transition to the RT2 game state described later (winning role “maintain bell”) Is displayed on the active line A, as shown in (1) of FIG. 6, the gaming state is shifted to the RT2 gaming state, and if the gaming state is the RT2 gaming state, an auxiliary effect is performed. The symbol combination corresponding to the winning combination indicating the transition to the RT3 gaming state (winning combination “transition replay 4”), which will be described later, is displayed on the active line A, as shown in (2) of FIG. If the gaming state is shifted to the RT3 gaming state and the gaming state is the RT3 gaming state, an auxiliary effect is performed, and a winning combination indicating a transition to the RT4 gaming state described later (winning role “Transition Replay 5” or “Transition Replay 6” is performed. ]) That that symbol combination is displayed on the pay line A, as shown in (3) in FIG. 6 shifts the gaming state to RT4 gaming state. Thus, the gaming state transitions to the RT4 gaming state, and the ART gaming state is executed.

  Then, when the end condition of the AT effect state is satisfied, the AT effect state is ended in the ART game, and the auxiliary effect is not performed, so that the transition to the RT2 game state is performed as shown in (4) of FIG. Is displayed on the active line A, so that the gaming state is shifted to the RT2 gaming state, or, as shown in FIG. 6 (5), the winning combination indicating the transition to the RT1 gaming state When the symbol combination corresponding to (winning combination “maintained bell”) is displayed on the active line A, the gaming state is shifted to the RT1 gaming state.

  In addition, in the winning type lottery in any of the RT1 gaming state, the RT2 gaming state, the RT3 gaming state, or the RT4 gaming state, if one of the winning combination “BB” is won and the BB internal winning flag is established, As shown in (6) of FIG. 6, the state transition means 312 shifts the gaming state to an internal middle gaming state corresponding to the bonus gaming state preparation state. At this time, when the symbol combination corresponding to the winning combination “BB” cannot be displayed on the active line A, the BB internal winning flag is carried over to the next game as it is (the internal medium gaming state is maintained). The symbol combination corresponding to the winning combination “BB” can be displayed on the active line A in the next and subsequent games. In the internal game state, the winning probability “normal replay” is set higher (for example, 1 / 3.0) than the preceding (immediately) game state, and the winning combination “increase bell” is set as described later. Since the winning probability of “1” and the winning combination “increased bell 2” is high, it is possible to aim to display the symbol combination corresponding to the winning combination “BB” on the active line A while suppressing consumption of medals. Then, when the player displays the symbol combination corresponding to the winning combination “BB” on the active line A, as shown in FIG. 6 (7), the state transition means 312 changes the gaming state to the internal middle game. Transition from state to bonus game state. Further, in the bonus game state, a predetermined number (for example, a bonus game state based on the winning combination “RBB1” = 351, a bonus game state based on the winning combination “RBB2” and the winning combination “RBB3” = 297, and the winning combination “CBB”. When the medals exceeding the bonus gaming state based on “81” are paid out, the state transition means 312 shifts the gaming state from the bonus gaming state to the RT1 gaming state as shown in (8) of FIG. However, as shown in (9) of FIG. 6, when the symbol combination corresponding to the winning combination “BB” is displayed on the active line A in the game in which the winning combination “BB” is established, Instead of going through, it changes directly to the bonus game state.

(Winning type lottery table)
FIG. 7 is a diagram showing a winning type lottery table used when determining a winning type lottery random number. In the winning type lottery table, a plurality of winning areas are sectioned, and the winning type as the object of the lottery varies depending on the gaming state, and the presence / absence of unsuccessful winning varies. In FIG. 7, the winning area (winning type) assigned for each gaming state (RT1 gaming state, RT2 gaming state, RT3 gaming state, RT4 gaming state, internal medium gaming state, bonus gaming state) is represented by “O”. ing. Therefore, a winning area in which “◯” is not described indicates that it is not assigned to the gaming state. Each partitioned area is associated with a predetermined winning range value (number) indicating the winning range and the winning type, and the winning range values of all the winning areas assigned to each gaming state are totaled. Then, it becomes the total number (65536) of winning type lottery random numbers. Accordingly, the probability that each winning category is determined is a value obtained by dividing the winning range value associated with the winning region by the total number of winning type lottery random numbers. The winning type lottery means 304 sequentially acquires a winning range value from a plurality of winning areas in the winning type lottery table based on the gaming state at that time, and subtracts the winning range value from the winning type lottery random number. When the subtraction value is less than 0, the winning type associated with the winning area at that time is set as the lottery result. The lottery procedure can be applied to other lotteries.

  According to the winning type lottery table of FIG. 7, the winning area “normal replay” is associated with the winning area 1 and corresponds to the winning combination “normal replay” in accordance with the winning of the winning type “normal replay”. The symbol combination to be displayed can be displayed on the effective line A.

  Moreover, according to the winning type lottery table, a plurality of winning combinations may win a winning type. For example, the winning area 2 is associated with a winning type “Transition Replay 1” in which the winning combination “Normal Replay” and “Transition Replay 4” overlap. As described above, when a plurality of winning combinations are won in duplicate, winning conditions regarding which symbol combination corresponding to which winning combination is preferentially displayed on the active line A, for example, the stop switch 130a, The order in which 130b and 130c are operated is set.

  In the following description, the operation of the stop switches 130a, 130b, and 130c for stopping the rotating reels in the order of the rotating reel 134a, the rotating reel 134b, and the rotating reel 134c is referred to as “batting order 1”. Further, the operation of the stop switches 130a, 130b, and 130c for stopping the rotating reels in the order of the rotating reel 134a, the rotating reel 134c, and the rotating reel 134b is referred to as “batting order 2”. Further, the operation of the stop switches 130a, 130b, and 130c for stopping the rotating reels in the order of the rotating reel 134b, the rotating reel 134a, and the rotating reel 134c is referred to as “batting order 3”. Further, the operation of the stop switches 130a, 130b, and 130c for stopping the rotating reels in the order of the rotating reel 134b, the rotating reel 134c, and the rotating reel 134a is referred to as “batting order 4”. Further, the operation of the stop switches 130a, 130b, and 130c for stopping the rotating reels in the order of the rotating reel 134c, the rotating reel 134a, and the rotating reel 134b is referred to as “batting order 5”. Further, the operation of the stop switches 130a, 130b, and 130c for stopping the rotating reels in the order of the rotating reel 134c, the rotating reel 134b, and the rotating reel 134a is referred to as “batting order 6”.

  For example, in the RT2 gaming state, when the winning type “Transition Replay 1” corresponding to the winning area 2 is determined by the winning type lottery and an operation according to batting order 1 is performed, the winning combination “Transition” indicating the transition to the RT3 gaming state is performed. The stop control is performed so that the symbol combination corresponding to “Replay 4” is preferentially displayed on the active line A. Further, when an operation according to batting order 2 to batting order 6 is performed, stop control is performed so that the symbol combination corresponding to the winning combination “normal replay” is preferentially displayed on the active line A.

  As described above, a winning type in which a plurality of winning combinations are overlapped is determined based on the combination of symbols that can be displayed on the active line A according to the operation order of the stop switches 130a, 130b, and 130c by the player, As shown in FIG. 7, when a combination is a small combination, a symbol combination corresponding to which winning combination is preferentially displayed on the active line A based on the number of medals paid out corresponding to the small combination. The reel control means 306 determines a symbol for stop control according to the operation order and operation timing of the stop switches 130a, 130b, 130c by the player. For example, when one of the stop switches 130a, 130b, 130c is operated by the player while the rotating reels 134a, 134b, 134c are rotating, the rotating reels 134a corresponding to the operated stop switches 130a, 130b, 130c. , 134b, 134c of the reels 134a, 134b, 134c of the symbol combinations corresponding to all winning combinations that still have a possibility of winning among the symbols existing in the drawing range at the operation timing. The reel control means 306 selects one of the symbols on the effective line A based on the priority set according to the operation order of the operated stop switches 130a, 130b, 130c. Control to stop. In this embodiment, when the priority is set based on the types of symbol combinations that can be displayed on the effective line A, the higher the number of symbol combinations of the winning combination that can be displayed on the effective line A, the higher the priority. When the priority is set so that the priority is set based on the number of medals to be paid out corresponding to the winning combination (small role), the small combination corresponding to the symbol combination displayed on the active line A is paid out. The priority is set such that the higher the number, the higher the priority.

  As mentioned above, when winning type “Migration Replay 1” is won, any overlapping winning combination will be possible no matter what timing the stop switches 130a, 130b, 130c are pressed on the symbol arrangement. The symbol combination corresponding to is always displayed on the effective line A. Therefore, even if the player operates the stop switches 130a, 130b, and 130c so that any of the rotary reels 134a, 134b, and 134c is stopped first, the symbol combination corresponding to the replay combination is displayed on the active line A. Is possible, but the combination of symbols displayed will differ depending on the order of stoppage.

  When such a winning combination of replay winning combinations is won, a symbol combination corresponding to any of a plurality of winning winning combinations can be displayed on the effective line A through the auxiliary effect. For example, when the state transition means 312 determines a transition to the AT effect state in the RT2 game state and then wins a predetermined winning type (for example, the winning type “Transition Replay 1”), the player is given the auxiliary effect through the auxiliary effect. Then, an operation according to a predetermined operation mode (for example, batting order 1) indicating the transition of the game state is performed, and a symbol combination corresponding to the predetermined winning combination (for example, the winning combination “transition replay 4”) is displayed on the active line A. Accordingly, the gaming state is changed to the RT3 gaming state.

  In addition, when the winning type “selected bell left 1” corresponding to the winning area 14 is determined by the winning type lottery and the operation according to the batting order 1 is performed, the symbol combination corresponding to the winning combination “increasing bell 1” with a large number of payouts Is controlled so that is preferentially displayed on the active line A. As described above, the symbol combinations corresponding to the winning combination “Increase Bell 1” are arranged so that they can be displayed on the active line A by stop control (see FIGS. 3 and 5). Further, when an operation according to batting order 2 to batting order 6 is performed, stop control is performed so that a symbol combination corresponding to any of the overlapping winning combination “maintenance bell” is preferentially displayed on the active line A. . However, even if the winning combination “maintenance bell” is won, the player does not necessarily display the symbol combination corresponding to the winning combination “maintenance bell” on the active line A. As described above, when the winning type “selected bell left 1” in the winning area 14 is won, if the player operates according to the batting order 1 that is the correct operation mode, it corresponds to the winning combination “increase bell 1” with 9 payouts. The symbol combination to be displayed can always be displayed on the active line A (expected number of winnings = 9), and if operated according to the batting order 2 to 6, the winning combination of three payouts is avoided while avoiding winning of the winning combination “Increase Bell 1” The symbol combination corresponding to “Maintenance Bell” can be displayed on the active line A with a probability of about ½, and any winning combination will not be won with a probability of the remaining ½ (missing) Can do.

  Here, in all the winning areas 14 to 25 of the winning type lottery table, any one of the winning combination “Increase Bell 1” and “Increase Bell 2” and any of the winning combinations “Maintenance Bell 1” to “Maintenance Bell 24” are plural. The winning combination of “the selection bell left 1”, “the selection bell left 2”, “the selection bell left 3”, and “the selection bell left 4” in the winning areas 14 to 25 are selected. , “Selection Bell Right 1”, “Selection Bell Right 2”, “Selection Bell Right 1”, “Selection Bell Right 3”, “Selection Bell Right 4” may be abbreviated as “Selection Bell” in some cases), and the winning combination “Increase Bell 1” in which the expected number of winnings is greater than the winning combination “Maintenance Bell 1” to Winning Role “Maintenance Bell 24” Or stop operation to win the winning role “Increase Bell 2” depending on the winning area It is set to be. Note that the winning probabilities (numbers of numbers) of the winning regions 14 to 25 are set to be equal. Since the player cannot usually know which winning type is won, by providing the winning areas 14 to 25 as described above, the winning combination “Increase Bell 1” or It has become extremely difficult to win the winning role “Increase Bell 2”. However, even if the player wins a winning type in which the player's gaming profit differs depending on the order of operation of the stop switches 130a, 130b, and 130c, the player can win the winning combination “Increase Bell 1” or the winning combination By grasping the correct operation mode that can win “Increase Bell 2”, the symbol combination corresponding to the winning combination “Increase Bell 1” or “Increase Bell 2” is displayed on the active line A, and the auxiliary effect is not executed. More medals can be obtained than in the non-AT effect state.

  As described above, by executing the auxiliary effect, the AT effect state (ART game state executed in parallel with the RT4 game state in the present embodiment) in which medals are likely to increase as the game progresses, and the auxiliary effect are performed. By not having this, it is possible to realize a non-AT effect state (mainly RT1 gaming state, RT2 gaming state, RT3 gaming state) in which medals tend to decrease as the game progresses. Specifically, in the non-AT effect state in which the assist effect is not performed, when the player operates the stop switch 130 in a random operation manner in the game selected by the winning type “Selection Bell”, the specified input number “3”. On the other hand, the expected number of winnings is about 2.75 (9 × 1/6 + about 3/2 × 5/6), and the number of medals easily decreases as the game progresses. On the other hand, in the AT effect state where the assist effect is executed, the winning combination “Increase Bell 1” or the winning combination “Increase Bell 2” can be won in the game won by the winning type “Selection Bell”. The expected number of winnings is 9 with respect to the number of inserted “3”, and by adjusting the winning probability of the winning type “selected bell”, it is possible to realize a game in which medals are likely to increase as the game progresses.

(Direction state transition)
FIG. 8 is an explanatory diagram for explaining the transition of the effect state on the main control board 200. Hereinafter, the effect state (non-AT effect state, AT effect state) that is transitioned (set) by the state transition means 312 in the main control board 200 will be described in detail.

(Non-AT production state)
The non-AT effect state includes a normal effect state and a chance effect state. When the non-AT effect state is executed, the frequency of the auxiliary effect is much lower than that of the AT effect state, and almost no auxiliary effect is performed or no auxiliary effect is performed, so the number of medals that can be acquired is limited. The The normal performance state is a game state corresponding to an initial state among a plurality of performance states managed by the sub control board 202.

  The state transition means 312 changes the game state to the chance effect state at a predetermined trigger in the normal effect state (1), and when a predetermined condition is satisfied in the chance effect state, for example, a predetermined number of games is consumed. Then, the normal production state is restored (2). Further, the state transition means 312 can transition the effect state to the AT effect state in the normal effect state and the chance effect state (3). However, the chance effect state is set so that it is easier to shift to the AT effect state than the normal effect state. For example, in any game state of the normal effect state and the chance effect state, it is determined by lottery (effect state lottery) whether or not to shift to the AT effect state based on the winning type determined by the winning type lottery. In addition, the probability of shifting to the AT effect state associated with each winning category is higher in the chance effect state than in the normal effect state. Therefore, the player desires to stay in the chance effect state rather than the normal effect state. Further, when the predetermined number of games is consumed in the non-AT effect state without shifting to the AT effect state (so-called ceiling arrival), the state transition means 312 changes the game state to the AT effect state.

(AT production state)
In the AT effect state, it is possible to acquire many medals while suppressing the consumption of medals by notifying the correct operation mode by the assist effect. Therefore, the player can advantageously advance the game in the AT effect state compared to the non-AT effect state.

  In the AT effect state, two AT effect states (a normal AT effect state and a chance AT effect state) are provided. In the normal AT effect state, a predetermined number of continuous games (for example, 50 games) is set as one set, and the game progresses by managing the number of sets. When the effect state is set to the normal AT effect state, the state transition means 312 subtracts 1 from the number of stocks (held) and sets the number of continued games to 50 games. When the game of the number of continuous games is completed, the state transition means 312 determines whether the number of sets is 0 (whether the number of sets is stocked). If the number of sets is not 0, the stocked set The normal AT effect state is continued by subtracting 1 from the number (4). On the other hand, when the number of stocked sets is 0, the state transition means 312 ends the normal AT effect state, and transitions the effect state to the normal effect state (5). Further, the state transition means 312 can transition the effect state to the chance AT effect state in the normal AT effect state (6).

  The chance AT effect state continues until a predetermined number of games elapses, during which the number of sets in the normal AT effect state is added. When the predetermined number of games is over, the state transition means 312 transitions the effect state to the normal AT effect state (7).

(Display of game information)
By the way, if the frequency of transition to the bonus game state or the AT effect state as described above is biased, there is a concern that the shooting performance may be excessively increased. Therefore, in order to comprehensively and uniformly determine whether or not the gaming state with high medal acquisition performance is biased, determination criteria such as an advantageous section ratio, a continuous combination ratio, and a combination ratio are provided. The advantageous section ratio is the number of games staying in the advantageous section divided by the total number of games, which is the total number of games, and is expressed as a percentage. The total number of medals paid out by the payout control means 310, which is the number of medals paid out by the payout control means 310 due to the operation of the first type special character such as a regular bonus game during the reference counting period. Divide by the total number of payouts and say the value expressed as a percentage. The character ratio is the number of medals paid out by the payout control means 310 based on the operation of the character such as a bonus game in a predetermined reference counting period. The number of items paid out is divided by the total number of payouts, which is the total number of medals paid out by the payout control means 310, and is a value expressed in%.

  Here, the advantageous section refers to a section in the AT effect state (including the normal AT effect state, the chance AT effect state, and the preparation state thereof). Therefore, the advantageous section ratio represents the ratio of the number of stay games played in the AT effect state to the total number of games in the AT effect state and the non-AT effect state. Note that the non-AT effect state may be referred to as a normal section with respect to the advantageous section. However, the advantageous section is not limited to the AT effect state, and any one of the game state and the effect state in which the game progresses advantageously for the player may be arbitrarily set.

  The bonus is a device for facilitating winning, and includes a regular bonus (RB), a challenge bonus (CB), a single bonus (SB), and the like. Moreover, a regular bonus (RB) respond | corresponds to a 1st type special actor among such actors. The regular big bonus (RBB) is a regular bonus (RB) that operates continuously regardless of the display of the symbol combination indicating the winning pattern of the regular bonus (RB), which is the first type special bonus, The Challenge Big Bonus (CBB) is a series of Challenge Bonuses (CB) regardless of the symbol combination indicating the winning type of the Challenge Bonus (CB), which is the second type special character (one of the characters). It works with. Therefore, the continuous feature ratio represents the ratio of the number of consecutive feature payouts paid out by the operation of the first type special feature to the total number of payouts paid out during the predetermined standard aggregation period. Represents the ratio of the number of paid-out items by the operation of the bonuses to the total number of paid-outs in the predetermined reference tabulation period.

  The reference tabulation period is a target period in which the number of medals paid out by the payout control unit 310 is accumulated. In the present embodiment, for example, there are two types of 6000 games, which are finite values, and all periods (hereinafter referred to as “total cumulative”) after the slot machine 100 is installed in the game hall (hall). Therefore, as the consecutive character ratio, the consecutive character ratio of 6000 games and the total cumulative character ratio are derived, and as the character ratio, the 6,000 game character ratio and the total cumulative character ratio. And derived. However, it goes without saying that an arbitrary number of games can be set as the reference tabulation period.

  In order to obtain such an advantageous section ratio, continuous feature ratio, and accessory ratio, the accumulating means 314 accumulates the total number of games, the number of stay games, the total number of payouts, the number of consecutive feature payouts, and the number of payouts of features. . At this time, a counter is associated with each of the total number of games, the number of staying games, the total number of payouts, the number of consecutive winnings, and the number of winnings. Specifically, when one game is started, the accumulation means 314 increments the total game number counter indicating the total number of games by one. Then, it is determined whether or not the current game is a game in the AT effect state, and if the game is in the AT effect state, the stay game number counter indicating the number of stay games is incremented by one. The stay game number counter is updated from the next game of the game won in the AT effect state (the game that has been transferred to the advantageous section) when the effect state is the non-AT effect state. However, if the AT effect state is won based on the winning of the regular big bonus (RBB) or the challenge big bonus (CBB), the game that has won the bonus (the game in which the transition process to the advantageous section has been performed) Start with a game.

  Further, when the medal is paid out in the game, the accumulating means 314 increments the total payout number counter indicating the total payout number by the payout number. If the payout of the medal is based on an accessory, the accessory payout counter indicating the number of payout of the accessory is incremented by the number of payouts, and the payout of the medal is changed to the first type special accessory. If it is based, the consecutive feature payout number counter indicating the number of consecutive feature payouts is incremented by the number of payouts.

  Note that the total cumulative number can be counted only with such a counter. However, regarding the continuous character ratio and the character ratio, not only the total cumulative value but also a limited period such as 6000 games in this case must be covered. I must. Therefore, for example, 6000 games are equally divided every 400 games, and a plurality of (for example, 15) counters for counting 400 games are provided and used as a ring buffer. Here, an example is given in which 6000 games are divided and counted every 400 games, but it goes without saying that the number of games to be divided can be arbitrarily set as long as it is a factor of 6000 (divisor).

  Specifically, when the medal is paid out in the game, the accumulating means 314 performs a process of updating the total payout counter, the continuous feature payout counter, and the bonus payout counter up to 400 games, and reaches 400 games. The total number of payouts, the number of consecutive payouts, and the number of payouts are derived by adding together the 14 counters counted in the past. Then, the counter counted by the oldest game among the 14 counters is initialized, and 400 counter games, a total payout counter, a continuous feature payout counter, and an accessory payout counter are newly added by the initialized counter. Update. Thus, for every 400 games, it is possible to refer to the game information for 400 new games and the game information for the past 5600 games, so the total number of payouts, the number of consecutive feature payouts, It is possible to derive the number of goods paid out. The counting by such a counter is always executed regardless of the specified number or set value. In this way, the total number of games, the number of stay games, the total number of payouts, the number of consecutive feature payouts, and the number of payouts of items are accumulated.

  Subsequently, the ratio deriving unit 316 accumulates the total number of games, the number of staying games, the total number of paid-outs, the number of consecutive feature payouts, the number of featured payouts accumulated by the accumulating unit 314, Deriving the ratio of the actors. Specifically, the ratio deriving unit 316 divides the number of stay games by the total number of games, derives an advantageous section ratio by converting the percentage into percentages, and divides the total cumulative number of consecutive payouts by the total total number of payouts. The percentage of total consecutive features is derived in terms of%, and the number of total feature withdrawals is divided by the total number of total withdrawals, and the percentage is calculated in terms of%. Further, the ratio deriving means 316 divides the number of consecutively paid out 6000 games by the total number of paid out 6000 games for every 400 games and derives the ratio of 6000 consecutively played games by converting the percentage into 6000 games. Divide the number of paid-out items by the total number of paid-out games of 6000 games, and calculate the percentage of 6000 games as a percentage.

  Next, the ratio display means 318, based on a predetermined display command, the advantageous section ratio derived by the ratio derivation means 316, the 6000 game continuous character ratio, the 6000 game character ratio, and the total cumulative continuous character ratio. , The total cumulative proportion of the objects is displayed on the ratio display section 160.

  FIG. 9 is an explanatory view showing the appearance of the main control board 200. As shown in FIG. 9A, a plurality of connectors 170 are provided on the end side of the main control board 200, and a ratio display unit 160 is provided near the center of the main control board 200. The ratio display unit 160 is configured by juxtaposing four seven segments including seven segments that can represent decimal Arabic numerals and a dot segment (DP) positioned at the lower right of the seven segments. When the main control board 200 is incorporated into the slot machine 100, the main control board 200 is accommodated in the board case 172 as shown in FIG. Fix with screws 174 from the back. A transmission window 172b through which the ratio display unit 160 can be viewed is provided at a position corresponding to the ratio display unit 160 in the front surface portion 172a of the substrate case 172. Therefore, as shown in FIG. 2, the administrator can visually recognize the display content of the ratio display unit 160 through the transmission window 172 b with the front upper door 104 opened. Instead of the transmissive window 172b, the entire substrate case 172 may be formed of a transmissive or semi-transmissive material.

  Here, there are only four seven segments constituting the ratio display unit 160, and an advantageous section ratio, a 6000 game continuous character ratio, a 6000 game character ratio, a total cumulative consecutive character ratio, and a total cumulative character ratio. In order to display such five pieces of game information, an identifier is associated with each ratio, and the identifier and each ratio are sequentially displayed on the ratio display unit 160. In addition, each ratio is shown in the range of 0-99. Therefore, out of the four 7 segments, two 7 segments located on the left side indicate an identifier, and two 7 segments located on the right side indicate a ratio.

  FIG. 10 is an explanatory diagram for explaining a display mode of the ratio display unit 160. When the power switch 148 is turned on, as shown in FIG. 10A, the ratio display means 318 displays “7U”, which is an identifier corresponding to the advantageous section ratio, and its ratio, for example, “70”% at a time. indicate. The ratio display unit 318 divides the identifier and the ratio by lighting the second seven-segment dot segment of the ratio display unit 160.

  In this state, when a predetermined time (for example, 5.0 sec) elapses, as shown in FIG. 10 (b), the ratio display means 318 displays “6Y”, which is an identifier corresponding to the consecutive character ratio of 6000 games, and its ratio. "60"% is displayed at a time. Each time a predetermined time elapses, as shown in FIG. 10C, a combination of “7Y”, which is an identifier corresponding to the ratio of 6000 games, and “70”%, which is the ratio, A combination of “6A”, which is an identifier corresponding to the total cumulative feature ratio as shown in (d), and “60”% as the ratio, and a total cumulative role as shown in FIG. A combination of “7A” that is an identifier corresponding to the object ratio and “70”% that is the ratio is sequentially displayed. Further, as shown in FIG. 10E, a combination of “7A” that is an identifier corresponding to the total cumulative feature ratio and “70”% that ratio is displayed for a predetermined time. When the time elapses, the identifier “7U” corresponding to the advantageous section ratio shown in FIG. 10A and the ratio “70”% are displayed again, and each time a predetermined time elapses thereafter. The display is switched in the order of an advantageous section ratio, a 6000 game continuous character ratio, a 6000 game character ratio, a total cumulative character ratio, and a total cumulative character ratio.

  Here, an example has been described in which identifiers and ratios are simultaneously shown with four seven segments, but it is also possible to switch between identifiers and ratios using only two seven segments. In this case, the ratio display unit 318 causes the ratio display unit 160 to display, for example, “7U” → “70” → “6Y” → “60” → “7Y” → “70” → “ The display is switched in the order of “6A” → “60” → “7A” → “70”.

  Note that the ratio display means 318 replaces the ratio display section 160 of the main control board 200 with the identifier and ratio in the existing display sections (main credit display section 152 and main payout display section 154) corresponding to four seven segments. Can also be displayed. In this case, after the result of one game is notified and before the start of the next game, the front upper door 104 is opened, and in that state, an operation to set or change an existing switch, for example, a set value is executed. By operating the switch, an identifier corresponding to the advantageous section ratio and the ratio are displayed. After that, every time a predetermined time elapses, the advantageous section ratio → the 6000 game continuous character ratio → the 6000 game character ratio The display will be switched repeatedly in the order of the total cumulative feature ratio → total cumulative feature ratio. In addition, the ratio display means 318 displays an advantageous section ratio, a 6000 game continuous character ratio, a 6000 game character ratio, a total cumulative character ratio, and a total cumulative character ratio on an existing display unit. Even if the slot machine 100 is changed, such as when a medal is inserted, the display is deleted.

  The administrator can use the ratio display unit 160 or the existing display unit to obtain an advantageous segment ratio, a 6000 game continuous character ratio, a 6000 game character ratio, a total cumulative character ratio, and a total cumulative character value. Game information such as a ratio can be visually recognized. Then, it is possible to determine whether or not the game information is within an appropriate range and determine whether or not the slot machine 100 is operating properly.

  Such an appropriate range is, for example, an advantageous section ratio <70%, a 6000 game continuous feature ratio <60%, a 6000 game feature ratio <70%, a total cumulative feature ratio <60%, a total cumulative ratio It is set that the ratio of items is <70% When it deviates from such an appropriate range, the ratio display unit 318 may blink each segment of the ratio display unit 160 with a period of 0.6 sec, for example, regarding the target ratio. With this blinking display, the administrator can quickly grasp the identifiers deviating from the appropriate range and their ratios.

  By the way, as described above, the ratio deriving unit 316 derives the advantageous section ratio by dividing the number of stay games by the total number of games, and divides the total number of consecutive payouts by the total number of total payouts. The total cumulative number of consecutive feature payouts is derived, and the total cumulative feature payout number is divided by the total cumulative total number of payouts to derive the total cumulative feature payout number. However, the main CPU 200a on the main control board 200 has a low processing capability, and the division command that can be used by the main CPU 200a is limited in the range of the dividend and divisor. For example, in a DIV instruction that executes division and is prepared in advance as an arithmetic instruction in the main CPU 200a, both the dividend and the divisor are limited to a 2-byte numerical range, that is, only a range from 0 to 65535 is handled. I can't. On the other hand, it is assumed that the total number of games is, for example, 175,000 games or more. Therefore, the numerical value range is exceeded and the DIV instruction cannot simply be used. In this case, a program that repeats multiplication and subtraction must be prepared separately as in the case where a person performs division by hand, resulting in an increase in processing load. Therefore, an object of the present embodiment is to appropriately obtain game information while suppressing an increase in processing load.

(Derivation processing of each ratio)
Here, a plurality of processing examples for deriving each ratio (advantageous section ratio, continuous accessory ratio, and accessory ratio) will be described. First, a portion common to the plurality of processes will be described in detail. In the present embodiment, values that are finally converted to% are obtained as the advantageous section ratio, the continuous accessory ratio, and the accessory ratio. This indicates that only two digits after the decimal point are necessary for the result of division. In this embodiment, the value after the decimal point when converted to% is rounded down. This means that if only 2 digits after the decimal point can be derived from the division result, an operation after 3 digits after the decimal point is not required. Therefore, in the present embodiment, a predetermined multiplicand (here, 100) is multiplied to carry the result of division by two digits. In this example, since only two decimal places are required, a multiplicand is multiplied by “100”. However, when three decimal places are necessary, the multiplicand is multiplied according to the required number of digits, such as by multiplying “1000” as the multiplicand. Can be changed.

  In addition, here, the “object ratio” is described as an object of the derivation process, but it goes without saying that the same process can be applied to the advantageous section ratio and the continuous accessory ratio. As described above, the bonus rate is derived by dividing the bonus payout count by the total payout count and converting it into%. This “% conversion” point corresponds to multiplication by the multiplicand “100”. Therefore, it can be expressed by an equation such as a ratio of an accessory = number of payouts of an accessory ÷ total number of payouts × 100. However, since the number of items paid ≤ total number of payouts, unless the number of items paid out = total number of payouts, the order of this formula is always the value after the decimal point when the number of items paid out ÷ total number of payouts. For example, the main CPU 200a cannot perform computation.

  Therefore, the calculation order is changed, and the calculation is performed in the order of an accessory ratio = number of payouts of an accessory × 100 ÷ total number of payouts (an order of first multiplying by a multiplicand and then dividing by the total number of payouts). By doing so, it is possible to complete the calculation result with only the integer without performing the calculation after the decimal point, and as a result, the truncation after the decimal point is easily realized.

(First calculation example)
FIG. 11 is a flowchart illustrating a first calculation example of an accessory ratio, and FIG. 12 is an explanatory diagram for explaining specific processing of the calculation. Here, it is assumed that the bonus payout ratio is “7123” and the total payout count is “10000”. Here, the division exceeding the numerical range (0 to 65535) is realized by replacing the division with the subtraction.

  First, the ratio deriving means 316 determines whether or not the number of paid-out items is larger than the total number of payouts (S1). As a result, if it is determined that the number of paid-out items is larger than the total number of paid-outs (YES in S1), the result that the number of paid-out items or the total number of paid-outs is not an appropriate value is abnormal. And the calculation process is terminated (S2). If it is determined that the number of items paid out is equal to or less than the total number of payouts (NO in S1), the ratio deriving unit 316 determines whether or not the total number of payouts is 0 (S3). As a result, if the total number of payouts is 0, that is, if medals have not yet been paid out (YES in S3), it is determined that the accessory ratio is 0% and the calculation process is terminated (S4). ). If it is determined that the total number of payouts is not 0 (NO in S3), the ratio deriving means 316 determines whether or not the item payout number is equal to the total payout number (S5). As a result, if it is determined that the number of paid-out items is equal to the total number of paid-outs (YES in S5), it is determined that the rate of bonuses is 99%, and the calculation process is terminated (S6). As described above, in the present embodiment, when the number of paid-out items is equal to the total number of pay-outs, 99% is originally shown as a bonus rate, which is 100%. By doing so, it becomes possible to represent all of the accessory ratios with two digits.

  If it is determined that the number of paid-out items is not equal to the total number of paid-outs (NO in S5), the ratio deriving unit 316 multiplies the number of paid-out items “7123” by the multiplicand “100” and holds it as a dividend (variable). At the same time (S7), the quotient (variable) is initialized to "-1" (S8). Subsequently, the ratio deriving unit 316 updates the dividend by subtracting the total payout number “10000” as a divisor from the dividend (S9), and adds 1 to the quotient (S10). Adding 1 to the quotient is equivalent to adding 1% to the ratio of items. Then, the ratio deriving unit 316 determines whether or not the updated dividend is less than 0 (S11). As a result, if it is determined that the updated dividend is less than 0 (YES in S11), the calculation process is terminated. Therefore, the quotient at this point becomes the accessory ratio as it is. If it is determined that the updated dividend is 0 or more (NO in S11), the process from the subtraction step S9 is repeated assuming that the accessory ratio has not yet been reached.

  The repetition of the processing from the subtraction step S9 will be described with reference to FIG. In the first subtraction step S9, the ratio deriving means 316 subtracts the dividend (total number of payouts) “10000” from the dividend “712300” obtained by multiplying the bonus payout number “7123” by the multiplicand “100” to obtain the dividend “ 702300 ". In the first addition step S10, the ratio deriving unit 316 adds “1” to the quotient “−1” and updates the quotient to “0”. When the same processing is repeated, in the 72nd subtraction step S9, the divisor (total payout number) “10000” is subtracted from the dividend “2300” to update the dividend to “−7700”, and in the 72nd addition step S10. , “1” is added to the quotient “70”, and the quotient is updated to “71”. At this time, since the dividend is negative (<0), the calculation process is ended, and the accessory ratio becomes the quotient “71” at that time. The quotient “71” corresponds to the number of subtractions (72nd to 1st) before the dividend (subtraction result) becomes negative (when the dividend is “2300”). This corresponds to an integer part of 71.23% obtained by dividing the total number of payouts “7123” by the total payout number “10000”, and can be understood to be correct.

  Note that the dividend becomes negative means that the number of subtractions is one more than the number corresponding to the original ratio of the actors. For example, in FIG. 12, the number of times “72” actually subtracted is one more than “71” times corresponding to the original accessory ratio “71”%. Therefore, “−1” is set as the initial value of the quotient as in the initialization step S8 so that the quotient at the time when the dividend becomes negative is used as it is as the accessory ratio.

  With this first calculation example, it is possible to realize division by only simple calculations such as addition, subtraction, and multiplication, and only by integers. Here, it is sufficient to repeat the process from at least the subtraction step S9 100 times. Further, if it is assumed that the fraction of the accessory ratio is rounded down, no error will occur, so that the accessory ratio can be accurately derived.

  In the above, it is assumed that the fraction of the actor ratio is rounded down. However, the present invention is not limited to this, and when rounding off the fraction of the actor ratio, the final dividend value (in this case, “ -7700 ") is rounded down if the absolute value is greater than 1/2 of the divisor (total payout number," 10000 "in this case), and rounded up if it is less than 1/2.

(Second calculation example)
In the first calculation example, the divisor is subtracted from the dividend repeatedly for the number of times corresponding to the accessory ratio (more precisely, +1). Then, the subtraction process is executed 100 times at the maximum. In the second calculation example, the number of subtraction processes is reduced by subtracting the divisor by multiplying it by an integer. For example, when the number of paid-out items is “7123” and the total number of payouts is “10000”, the divisor “10000” is not simply subtracted from the dividend “712300”, and the integer “10” is added to the divisor “10000”. By subtracting “100,000” multiplied, “7” corresponding to the second digit of the accessory ratio can be derived. Also, by subtracting the original divisor “10000” from the updated (subtracted) dividend, “1” corresponding to the first digit of the accessory ratio can be derived. In this way, by multiplying the divisor by an integer, the subtraction process can be reduced to at most 20 times here.

  However, since the main CPU 200a performs operations in binary numbers, here, the number “2” corresponding to the carry of the binary number is used instead of the number “10” corresponding to the carry of the decimal number. Therefore, here, a number obtained by multiplying the dividend “712300” by the predetermined integer “64 (2 6)”, which is a power of 2, is subtracted from the dividend “712300”. 2 to the 5th power) → 16 (2 to the 4th power) → 8 (2 to the 3rd power) → 4 (2 to the 2nd power) → 2 (2 to the 1st power) → 1 ( 2 to the 0th power) ", multiply by the divisor, and subtract from the dividend. Here, the integer that multiplies the divisor starts with 64, which is a power of 2, because the ratio of the objects falls within the range of 0 to 99. This is because there is no need to subtract.

  FIG. 13 is a flowchart illustrating a second calculation example of the accessory ratio, and FIG. 14 is an explanatory diagram for explaining specific processing of the calculation. Also here, as in the first calculation example, the bonus rate is derived assuming that the bonus payout number is “7123” and the total payout amount is “10000”. Since steps S21 to S26 are substantially the same as steps S1 to S6 in the first calculation example, description thereof is omitted here.

  If it is determined that the number of paid-out items is not equal to the total number of paid-outs (NO in S25), the ratio deriving means 316 multiplies the number of paid-out items “7123” by the multiplicand “100” and holds it as a dividend (variable). (S27), the integer (variable) is initialized to “64” (S28), the total payout number “10000” is set as the divisor (variable), and further multiplied by the integer “64” (S29), and the quotient (variable) ) Is initialized to “0” (S30). Subsequently, the ratio deriving unit 316 determines whether or not the dividend is greater than or equal to the divisor (S31). As a result, if it is determined that the dividend is equal to or greater than the divisor (YES in S31), the dividend is subtracted from the dividend to update the dividend (S32), and an integer is added to the quotient (S33). In this way, the proportion of the amount corresponding to the integer is added to the quotient. In the second calculation example, since the arithmetic processing is performed using integers that are powers of 2, the subtraction step S32 and the addition step S33 need only be executed at least once for each integer. The subtraction step S32 and the addition step S33 are not repeated a plurality of times, and the processing load can be reduced. Subsequently, the ratio deriving unit 316 updates the divisor by dividing the divisor by "2" (S34), and updates the integer by dividing the integer by "2" (S35). Thus, the preparation for the next subtraction step S32 is completed. In addition, the division of “2” in the division steps S34 and S35 is a one-bit right shift of binary numbers (LSB is deleted in the binary numbers, each bit is shifted by one digit (1-bit shift), and 0 is put in the MSB) Therefore, it is not necessary to use a DIV instruction.

  Then, the ratio deriving unit 316 determines whether or not the updated integer is less than 1 (S36). As a result, if the updated integer is less than 1 (exactly 1 ÷ 2 = 0.5, the decimal part is rounded down to 0), that is, the subtraction step S32 in the state where the integer is 1. If it is performed (YES in S36), the calculation process is terminated. Therefore, the quotient at this point becomes the accessory ratio as it is. If it is determined that the updated integer is equal to or greater than 1 (NO in S36), the process from determination step S31 is repeated assuming that the accessory ratio has not yet been reached.

  Such repetition of the processing from the determination step S31 will be described with reference to FIG. If it is determined in the first determination step S31 that the dividend is greater than or equal to the divisor, the ratio deriving unit 316 subtracts the divisor “64 × 10000” from the dividend “712300” to update the dividend to “72300” and “64” is added to “0” to update the quotient to “64 (1000000B in binary number)”. In the second to fourth determination steps S31, since the dividend <divisor, the subtraction step S32 and the addition step S33 are not executed. If it is determined in the fifth determination step S31 that the dividend is greater than or equal to the divisor, the ratio deriving unit 316 subtracts the divisor “4 × 10000” from the dividend “72300” to update the dividend to “32300” and “4” is added to “64” to update the quotient to “68 (1000100B in binary number)”. Similarly, if it is determined in the sixth determination step S31 that the dividend is greater than or equal to the divisor, the ratio deriving unit 316 subtracts the divisor “2 × 10000” from the dividend “32300” and updates the dividend to “12300”. , “2” is added to the quotient “68” to update the quotient to “70 (1000110B in binary number)”. If it is determined in the seventh determination step S31 that the dividend is greater than or equal to the divisor, the ratio deriving unit 316 subtracts the divisor “1 × 10000” from the dividend “12300” to update the dividend to “2300” and “1” is added to “70” to update the quotient to “71 (1000111B in binary number)”.

  When the process from the determination step S31 is repeated seven times, the integer is rounded down to 0 (<1), so that the calculation process ends and the accessory ratio is the quotient “71” at that time. It becomes. This corresponds to an integer part of 71.23% obtained by dividing the result of dividing the number of payouts “7123” by the total number of payouts “10000” into%, so that it can be understood that this calculation is correct.

  According to the second calculation example, division can be realized only by simple calculations such as addition, subtraction, and multiplication, and only by an integer. Further, here, it is sufficient to repeat the process from the determination step S31 seven times, so that the calculation process can be performed quickly. Further, if it is assumed that the fraction of the accessory ratio is rounded down, no error occurs, so that the accessory ratio can be accurately derived.

  In this case as well, it is assumed that the fraction of the accessory ratio is rounded down. However, the present invention is not limited to this case, and when the fraction of the accessory ratio is rounded off, the processing from the determination step S31 is repeated eight times. In the determination step S31, if it is determined that the dividend is greater than or equal to the divisor, it can be realized by adding 1 to the quotient.

(Third calculation example)
In the third calculation example, even when the dividend or the divisor exceeds 2 bytes, both are divided by the same integer so as to be within 2 bytes, and the DIV instruction available in the main CPU 200a is used.

  However, since the main CPU 200a performs operations in binary numbers, the number “2” corresponding to the carry of the binary number is used here instead of the number “10” corresponding to the carry of the decimal number. Therefore, here, the dividend “712300” and the divisor “10000” are sequentially divided by the integer “2”, and if the dividend falls within the range of 0 to 65535, the DIV instruction is executed.

  FIG. 15 is a flowchart showing a third calculation example of the accessory ratio, and FIG. 16 is an explanatory diagram for explaining specific processing of the calculation. Here, as in the first and second calculation examples, the bonus rate is derived assuming that the bonus payout number is “7123” and the total payout amount is “10000”. Since steps S41 to S46 are substantially the same as steps S1 to S6 in the first calculation example, description thereof is omitted here.

  If it is determined that the number of paid-out items is not equal to the total number of paid-outs (NO in S45), the ratio deriving unit 316 multiplies the number of paid-out items “7123” by the multiplicand “100” and holds it as a dividend (variable). At the same time (S47), the total payout number “10000” is set as a divisor (variable) (S48). Subsequently, the ratio deriving unit 316 determines whether the dividend or the divisor is out of a predetermined numerical range (here, 65536 or more), that is, whether it is out of the numerical range that can be used in the DIV instruction (S49). . As a result, if it is determined that the dividend or the divisor is outside the predetermined numerical range (YES in S49), the dividend is divided by “2” to update the dividend (S50), and the divisor is divided by “2”. Then, the divisor is updated (S51), and the processing from the determination step S49 is repeated. Thus, the dividend and the divisor can be reduced until both fall within a predetermined numerical range (until less than 65536). Note that the ratio between the dividend and the divisor does not change because both are repeatedly divided by the same integer “2” the same number of times. Here again, the division of “2” in the division steps S50 and S51 can be realized by a 1-bit right shift of a binary number, so that it is not necessary to use a DIV instruction.

  When the dividend and the divisor fall within a predetermined numerical range (here, less than 65536) (NO in S49), the ratio deriving unit 316 executes a DIV instruction that divides 2 bytes by 2 bytes (S52), The result is used as an accessory ratio.

  Such repetition of the processing from determination step S49 will be described with reference to FIG. If it is determined in the first determination step S49 that the dividend or the divisor is 65536 or more, the ratio deriving means 316 divides the dividend “712300” by the integer “2” and updates the dividend to “356150”. The divisor “10000” is divided by the integer “2” to update the dividend to “5000”. Similarly, in the second determination step S49, the ratio deriving unit 316 divides the dividend “356150” by the integer “2” to update the dividend to “178780”, and the divisor “5000” by the integer “2”. Divide and update the dividend to “2500”. In the third determination step S49, the divisor “178780” is divided by the integer “2” to update the dividend to “89037” and the divisor “2500” is changed to the integer “ Divide by 2 to update the dividend to “1250”. In the fourth determination step S49, the dividend “89037” is divided by the integer “2” to update the dividend to “44518” and the divisor “1250”. Is divided by the integer “2” to update the dividend to “625”. Then, since the dividend “44518” and the divisor “625” both fall within the predetermined numerical range (below 66536), the ratio deriving unit 316 executes the DIV instruction that divides 2 bytes by 2 bytes, An accessory ratio “71” can be derived. This corresponds to an integer part of 71.23% obtained by dividing the result of dividing the number of payouts “7123” by the total number of payouts “10000” into%, so that it can be understood that this calculation is correct.

  With this third operation example, it is possible to realize division by only simple operations such as multiplication, division by a DIV instruction, and bit shift, and by using only an integer, thereby reducing the processing load.

  In this case, since the number is reduced by reducing the resolution of the dividend and the divisor, an error may occur in the calculation result (the ratio of the accessory). However, since this error is one bit when one becomes less than 65535, the case where the error is maximum, that is, the dividend is “32768 (10000000B in binary number)”, and the divisor is “327”. The divisor (denominator) is 1 bit when expressed in binary (101000111B), so the error is 32768 / 327-32768 / 328 = 0.306%. As a result of the truncation, there is a possibility that the ratio of the accessory is reduced by 1%, but it is less than 2%, and the possibility is very low.

  Hereinafter, specific processing in the main control board 200 and the sub control board 202 will be described based on flowcharts.

(Main processing of main control board 200)
FIG. 17 is a flowchart showing main processing of the main control board 200. Here, first, an outline of one game after initialization will be described along the main process of the main control board 200, and then the details of each process will be described. Here, processing related to the features of the present embodiment will be described in detail, and descriptions of configurations unrelated to the features of the present embodiment will be omitted. Although detailed description is omitted, when each process is performed, the switches (the bet switch 126, the start switch 128, and the stop switches 130a, 130b, and 130c) used in each process are enabled at the start of the process. Invalidated at the end of processing.

(Step S100)
When the power of the slot machine 100 is turned on via the power switch 148 and becomes energized, the initialization unit 300 executes an initialization process in preparation for the start of the game. The initialization unit 300 generates backup data at any time while the power is on, and holds the backup data in the main RAM 200c. Therefore, even if an unexpected power interruption occurs, it is possible to restore the state before the power interruption using the stored backup data in this initialization process. For example, even if an unexpected power interruption occurs during the rotation of the rotating reels 134a, 134b, and 134c, the rotating reels 134a, 134b, and 134c are started again after the return operation. Therefore, in the initialization process, the main RAM 200c is basically not initialized (RAM clear).

(Step S200)
Subsequently, the betting means 302 bets medals through the operation of the bet switch 126 by the player or the insertion of medals into the medal insertion unit 124. Further, the command determining unit 320 generates a throw command indicating that the operation has been performed, and the command transmitting unit 322 transmits the generated throw command to the sub control board 202.

(Step S300)
Next, the winning type lottery means 304 validates the game start operation with respect to the start switch 128 and shifts to a state of waiting for the operation of the start switch 128. Here, the winning type lottery means 304 at the time when the start switch 128 is operated from the winning type lottery random number updated by the random number generator 200d of the main control board 200 in accordance with the operation of the start switch 128 by the player. 1 winning type lottery random number is acquired. Then, the winning type lottery means 304 determines one winning type lottery table corresponding to the currently set gaming state from the winning type lottery table shown in FIG. 7, and the acquired winning type lottery random number is determined. It is determined which winning area corresponds to the selected winning type lottery table, and the determined winning type or not winning is determined as the lottery result. In addition, after the lottery result is determined according to the operation of the start switch 128, the command determining unit 320 generates a winning type command including a lottery result (winning type or not winning) of the winning type lottery, information on the gaming state, and the like. Then, the command transmission unit 322 transmits the generated winning type command to the sub control board 202.

(Step S400)
When the start switch 128 is operated, the reel control unit 306 drives the stepping motor 262 to rotate the rotating reels 134a, 134b, and 134c. In this reel rotation process, when a predetermined time (for example, 4.1 seconds) elapses from the start of rotation of the rotation reels 134a, 134b, 134c in one previous game (for example, wait), the rotation reels 134a, 134b, When the rotation of the rotating reel 134a, the rotating reel 134b, and the rotating reel 134c has been rotated at a constant speed, the process proceeds to step S500.

(Step S500)
Subsequently, when the reel control means 306 activates the stop switches 130a, 130b, and 130c and receives an operation of the stop switches 130a, 130b, and 130c by the player, any of the reels 134a, 134b, and 134c corresponding to the operation is selected. To stop control. In addition, when any of the stop switches 130a, 130b, and 130c is operated, the command determination unit 320 displays a stop command (first stop command, second command) indicating information on the operated stop switches 130a, 130b, and 130c. A stop command, a third stop command) is generated for each operation, and the command transmission unit 322 sequentially transmits the generated stop command to the sub-control board 202.

(Step S600)
Next, the determination means 308 determines which combination the symbol combination displayed on the active line A shown in FIG. 3B corresponds to and determines the gaming state according to the symbol combination. Various processes required for change and replay are executed. In addition, the command determination unit 320 generates a winning command including a symbol combination displayed on the effective line A and a payout number of medals when a symbol combination corresponding to the small role is displayed on the effective line A. The command transmission means 322 transmits the generated winning command to the sub-control board 202.

(Step S700)
Subsequently, when the symbol combination corresponding to the small combination is displayed on the active line A based on the determination result in step S600, for example, the payout control unit 310 executes a medal payout process corresponding to the small combination. When the symbol combination corresponding to the replay combination is displayed on the active line A, a process for automatically betting the next game is executed. Further, when a predetermined number of medals are paid out in the bonus gaming state, the state transition unit 312 returns the gaming state to the gaming state before the transition from the bonus gaming state to the bonus gaming state, and corresponds to the gaming state. Set the winning type lottery table. Thus, the payout control means 310 performs various processes corresponding to the symbol combination displayed on the active line A, and ends the one game. The accumulating unit 314 accumulates the total number of games, the number of stay games, the total number of payouts, the number of consecutive feature payouts, and the number of payouts of items. The ratio deriving unit 316 is the total number of games, the number of stay games, the total number of payouts. Based on the number of consecutive feature payouts and the number of feature payouts, an advantageous section ratio, a continuous feature ratio, and an accessory ratio are derived. In addition, when the medal payout process is performed, the command determination unit 320 generates a payout command indicating that the payout process has been performed, and the command transmission unit 322 transmits the generated payout command to the sub-control board 202. . The payout process S700 will be described in detail later.

  One game is executed through a series of processes from step S200 to step S700. Thereafter, steps S200 to S700 are repeated.

  Further, when the ratio display means 318 receives a predetermined display command as an interrupt process, as explained with reference to FIG. The ratio display unit 160 displays the ratio of 6,000 games, the total cumulative ratio, and the total cumulative ratio.

(Payout process S700)
FIG. 18 is a flowchart showing the payout process in step S700. Here, the processing related to the features of the present embodiment, in particular, the advantageous section ratio, the continuous feature ratio, and the derivation processing of the feature ratio will be described in detail, and the description of the configuration unrelated to the features of the present embodiment is omitted. .

(Step S701)
First, the accumulation means 314 increments the total game number counter indicating the total number of games by one. Then, it is determined whether or not the current game is a game in the AT effect state, and if the game is in the AT effect state, the stay game number counter indicating the number of stay games is incremented by one. Further, when the medal is paid out in the game, the accumulating means 314 increments the total payout number counter indicating the total payout number by the payout number. If the payout of the medal is based on an accessory, the accessory payout counter indicating the number of payout of the accessory is incremented by the number of payouts, and the payout of the medal is changed to the first type special accessory. If it is based, the consecutive feature payout number counter indicating the number of consecutive feature payouts is incremented by the number of payouts. In this way, the total number of games, the number of staying games, the total number of payouts, the number of consecutive feature payouts, and the number of feature payouts are accumulated.

(Step S702)
Subsequently, the ratio deriving means 316 divides the number of stay games by the total number of games based on the total number of games and the number of stay games accumulated by the accumulating means 314, and derives an advantageous section ratio by converting the percentage.

(Step S703)
Next, the ratio deriving means 316 determines whether or not 400 games have elapsed since the last time the consecutive character ratio and the character ratio were derived. As a result, if 400 games have elapsed, the process proceeds to step S704, and if 400 games have not elapsed, the payout process S700 ends.

(Step S704)
If it is determined in step S703 that 400 games have elapsed, the ratio deriving unit 316 refers to the newly accumulated game information for 400 games and the game information for the past 5600 games, Deriving the continuous character ratio of 6000 games.

(Step S705)
Subsequently, the ratio deriving unit 316 refers to the newly accumulated game information for 400 games and the game information for the past 5600 games, and derives the latest 6000 game accessory ratio.

(Step S706)
Next, the ratio deriving unit 316 refers to all the past game information to which the game information for 400 games newly accumulated is added, and derives a total cumulative consecutive character ratio.

(Step S707)
Subsequently, the ratio deriving unit 316 refers to all the past game information to which the game information for 400 games newly accumulated is added, and derives the total accumulated character ratio.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to this embodiment. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Is done.

  For example, in the above-described embodiment, the main control board 200 and the sub control board 202 are arranged so as to share a functional part for proceeding with the game, but the functional part of the main control board 200 is assigned to the sub control board 202. Alternatively, the functional units of the sub control board 202 may be arranged on the main control board 200, or all the functional units may be arranged on one control board.

  In the above-described embodiment, the case where the three rotation reels 134a, 134b, and 134c are configured has been described. However, the rotation reels may be configured by two, four, or the like.

  Further, the processes performed by the main control board 200 and the sub control board 202 described above do not necessarily have to be processed in time series in the order described in the flowchart, and may include processes in parallel or by a subroutine.
