Description

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

In the slot machine as a game machine, a plurality of game states and production states having different degrees of advantage (game profit) of the player are provided as the game progresses. For example, there is a slot machine that adopts a specification that shifts from a normal game state to a bonus game state in which a player can easily obtain a medal by displaying a symbol combination corresponding to a bonus combination on an effective line.

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

(Table used in the main control board 200)
In the slot machine 100, a plurality of gaming states are provided on the main control board 200 and the sub-control board 202, and the gaming states change according to the progress of the game. Then, in the main control board 200, a plurality of winning type lottery tables and the like corresponding to the gaming states managed by the state transition means 312 are stored in the main ROM 200b. The winning type lottery means 304 has a current set value (indicating the easiness of obtaining a game profit stepwise) stored in the main RAM 200c and a current game state (a game state based on the presence or absence of a bonus combination described later). ), The corresponding winning type lottery table is extracted from the main ROM 200b, and based on the extracted winning type lottery table, the winning type lottery random numbers acquired according to the operation signal of the start switch 128 are in the winning type lottery table. Determine which winning type or non-winning is supported.

Here, the winning combinations that constitute the winning type extracted in the winning type lottery table include a replay combination, a small combination, and a bonus combination. The state in which the symbol combinations corresponding to such winning combinations are aligned on the valid line A is called display or winning, and until the winning combination including the winning combination is won and the symbol combination corresponding to the winning combination is displayed. The state of is the internal winning state. The replay role among the winning combinations is a role in which one game can be executed again without making a new bet of a medal by the player when the symbol combination corresponding to the replay combination is displayed on the valid line A. The small winning combination is a combination in which a predetermined number of medals can be paid out according to the symbol combination by displaying the symbol combination corresponding to the small winning combination on the effective line A. Further, the bonus combination is a winning combination capable of transitioning 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 effective line A. ..

Further, in the present 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”, "Transition Replay 5", "Transition Replay 6", "Transition Replay 7" (hereinafter, these eight replays may be simply abbreviated as the winning combination "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 10" 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 22", "Maintenance bell 23", "Maintenance bell 24", "Increase bell 1", "Increase bell 2" (hereinafter, winning combination "Maintenance bell 2" The 26 bells from "Bell 1" to "Maintenance Bell 24", "Increase Bell 1", and "Increase Bell 2" are simply abbreviated as the winning combination "Bell", and the winning combinations "Increase Bell 1" and "Increase Bell 2" are abbreviated. The 24 bells of the winning combination "Maintenance Bell 1" to "Maintenance Bell 24" may be simply abbreviated as the winning combination "Maintenance Bell"), "Cherry", "RBB1", "RBB2", "RBB3", "CBB" (hereinafter, the four winning combinations "RBB1", "RBB2", "RBB3", and "CBB" may be simply abbreviated as the winning combination "BB"). In FIG. 5, each of the rotary reels 134a, 134b, and 134c is associated with one or more symbols constituting each winning combination. Of these, the winning combination "replay" corresponds to the above replay combination, the winning combination "bell" and "cherry" correspond to the above small role, and the winning combination "BB" corresponds to the above bonus combination.

(Replay role)
Winning type As a result of the lottery, if you win a winning type that includes any of the winning combinations "replay" and operate in the operation mode (here, the operation order) that is the winning condition, the symbol combination corresponding to that winning combination Of these, when the symbols written on each of the rotating reels 134a, 134b, and 134c can be displayed on the effective line A, and 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.

Here, in the present embodiment, when the stop switch 130 is pressed by the player, if the symbols constituting the symbol combination corresponding to the winning combination are on the effective line A, the reel control means 306 is used. , Stop control is performed so that the symbol stops on the effective line A. Further, when the stop switch 130 is pressed, there is no symbol on the effective line A that constitutes the symbol combination corresponding to the winning combination, but the direction opposite to the rotation direction of each of the rotating reels 134a, 134b, 134c. When the symbols are within the range (pull-in range) corresponding to 4 frames of the above, the number of distant symbols becomes the number of sliding frames by the reel control means 306, and the symbol combination corresponding to the winning combination is configured. Stop control is performed so that the symbol to be drawn is pulled onto the effective line A and the rotation is maintained for the number of sliding frames and then stopped. Further, when there are a plurality of symbols corresponding to the winning combination in each of the rotary reels 134a, 134b, 134c and all of them are within the pull-in range of the respective rotary reels 134a, 134b, 134c, a predetermined priority is given. Which symbol is to be drawn onto the effective line A is determined according to the order, and stop control is performed so as to keep the rotation for the number of sliding frames so that the prioritized symbol is drawn onto the effective line A and then stop. When the stop switch 130 is pressed, if there is a symbol on the effective line A that constitutes a symbol combination corresponding to the winning combination other than the winning combination, the reel control means 306 transfers the symbol. A so-called kicking process that prevents the vehicle from stopping on the effective line A is also executed in parallel. 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 wins according to the operation mode of the player. The symbol combination corresponding to the combination is stopped and controlled so that it can be displayed on the effective line A.

Then, 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 always displayed on the effective line A by the above stop control. (See FIGS. 3 and 5). Specifically, the symbols that make up the symbol combination corresponding to the winning combination "normal replay" are separated by only a maximum of 4 frames within each of the rotating reels 134a, 134b, and 134c, so the stop control always enables the effective line. It can be displayed on A. In this way, when a winner is selected for a winning type that includes the winning combination "normal replay" and is operated in an operation mode that is a winning condition, the symbol combination corresponding to these winning combination "normal replay" is always an effective line. It will be displayed on A.

As will be described in detail later, the stop control when a winning combination including the winning combination "normal replay" is won is determined by the winning mode (for example, whether the winning combination "normal replay" is won alone or another winning combination. It is set to differ depending on the combination (for example, whether the winning combination "Transition Replay 1") and the winning combination are duplicated. Therefore, depending on the winning mode and the operating mode of the player, the symbol combination corresponding to any of the winning combinations of the winning combination "replay" that has been won in duplicate is displayed on the effective line A.

(Small role)
In addition, as a result of the winning type lottery, if any of the winning combination "bells" is included in the winning type, the symbol combinations corresponding to the winning combination are described in each of the rotating reels 134a, 134b, and 134c. When the symbol to be played is displayed on the valid line A and the symbol combination corresponding to the winning combination "bell" is displayed on the valid line A, the number of medals corresponding to each winning combination is paid out to the player. Is done.

In addition, the winning combination "maintenance bell 1" to "maintenance bell 24" is won in the winning type, and the operation order associated with the specific conditions (winning combination "maintenance bell 1" to "maintenance bell 24") is used. When the operation) is satisfied, the symbol combinations corresponding to the winning combinations "maintenance bell 1" to "maintenance bell 24" are not always displayed on the effective line A.

Further, as will be described in detail later, in the present embodiment, the winning combination "increase bell 1" and "increase bell 2" are not independently won, and other winning combinations (for example, the winning combination "maintenance bell 1" are always won. (One or a plurality of winning combinations selected from the winning combination "maintenance bell 24") and the winning combination), so that the stop control is set to be different depending on the winning mode of the duplicate winning combination. Therefore, although the symbol combinations corresponding to the winning combinations "increasing bell 1" and "increasing bell 2" are arranged so that they can always be displayed on the valid line A (see FIGS. 3 and 5), the winning combination "increase bell 1" Even if the winning type including "increase bell 1" and "increase bell 2" is won, it may be missed depending on the operation mode, and the player may miss the winning combination "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.

Further, as a result of the winning type lottery, when 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 effective 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 omission may occur, and the player does not necessarily put the symbol combination corresponding to the winning combination "cherry" on the effective line A. It is not always displayed.

(Bonus role)
In addition, as a result of the winning type lottery, if any of the winning combinations "BB" is included in the winning type, among the symbol combinations corresponding to the winning combination "BB", the rotating reels 134a, 134b, 134c The symbols written on each can be displayed on the effective line A. For example, when a winning combination including the winning combination "RBB1" is won, each of the rotating reels 134a, 134b, and 134c is described in each of 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. Then, when the symbol combination corresponding to the winning combination "RBB1" is displayed on the valid line A, the bonus game flag is turned on, the game state is set to the bonus game state, and the next one game (hereinafter, simply). After that (referred to as the next game), it is possible to execute the game in the bonus game state until a predetermined number of medals are paid out. In each of the rotary reels 134a, 134b, and 134c, the "BAR" symbols are arranged so that they may not be displayed on the effective line A even by the above stop control (see FIGS. 3 and 5). ). Therefore, even if the winning combination including the winning combination "RBB1" is won, the player is not always able to display the symbol combination corresponding to the winning combination "RBB1" on the effective line A.

When any of the above-mentioned winning types is won, the internal winning flag corresponding to each winning type is established (on), and the rotary reels 134a, 134b, and 134c are respectively established according to the establishment status of the internal winning flag. Stop control will be made. At this time, if the winning type including the small winning combination is won, but the symbol combination corresponding to these winning combination cannot be displayed on the effective line A in the one game, the one game After the end, the internal winning flag is turned off. That is, the right to win a small winning combination is limited to one game that is won in the winning type including the small winning combination, 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 (on) and the symbol combination corresponding to the winning combination "BB" is on the effective line A. Until it is displayed, the BB internal winning flag is carried over across the game. In addition, when the internal winning flag corresponding to the winning type including the winning combination "replay" which is the replay combination is established, the symbol combination corresponding to the winning combination is always displayed on the valid line A and a medal is required. The internal winning flag is turned off after the processing necessary for performing the next game is performed without fail.

(Transition of game state)
Here, with reference to FIG. 6, the transition of the gaming state including the bonus gaming state will be described. 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 winning probabilities of the replay combination were set for each of the RT1 game state, RT2 game state, RT3 game state, and RT4 game state (RT1 game state = 1 / 7.3, RT2 game state = 1 / 7.3, RT3 game). State = 1 / 1.4, RT4 game state = 1 / 1.4), which is a so-called RT game state, and as will be described later, mainly a predetermined winning combination is displayed on the valid line A for RT game. The state changes. Here, the winning probability of the replay combination in the RT4 game state is set to be relatively high, and the player can advance the game advantageously by shifting to the RT4 game state. Further, in the RT4 game state, it is assumed that the so-called AT is executed in parallel to perform the auxiliary effect (AT effect state), and in the present embodiment, the AT is executed in parallel with the RT4 game state. The state in which the game is played is called the ART game state.

The state transition means 312 transitions the plurality of gaming states based on the winning or winning of a predetermined winning type such as the winning combination "replay" or the 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 by the effect state lottery based on the winning type determined by the winning type lottery. When the transition to the AT effect state is determined by the effect state lottery, the game state shifts to the RT4 game state, and the ART game state in which the AT effect state and the RT4 game state proceed in parallel is executed. To. The production state will be described in detail later.

Specifically, when the transition to the AT effect state is determined, if the game state is the RT1 game state, an auxiliary effect is performed, and a symbol combination indicating the transition to the RT2 game state described later (winning combination "maintenance bell"" Is displayed on the effective line A, and 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. As shown in (2) of FIG. 6, the symbol combination corresponding to the winning combination (winning combination "transition replay 4") indicating the transition to the RT3 gaming state, which will be described later, is displayed on the effective line A. The game state is shifted to the RT3 game state, and if the game state is the RT3 game state, an auxiliary effect is performed, and the winning combination indicating the transition to the RT4 game state described later (winning combination "transition replay 5" or "transition replay 6"). By displaying the symbol combination corresponding to ()) on the effective line A, the gaming state is shifted to the RT4 gaming state as shown in (3) of FIG. In this way, 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 of the ART game ends and the auxiliary effect is not performed, so that the state shifts to the RT2 game state as shown in FIG. 6 (4). The game state is shifted to the RT2 game state by displaying the symbol combination indicating the above on the effective line A, or as shown in FIG. 6 (5), the winning combination indicating the transition to the RT1 game state. The game state is shifted to the RT1 game state by displaying the symbol combination corresponding to (winning combination “maintenance bell”) on the effective line A.

In addition, in the winning type lottery in any of the RT1 gaming state, RT2 gaming state, RT3 gaming state, and RT4 gaming state, if one of the winning combinations "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 the internal medium gaming state corresponding to the preparation state of the bonus gaming state. At this time, if the symbol combination corresponding to the winning combination "BB" cannot be displayed on the effective line A, the BB internal winning flag is carried over to the next game as it is (the internal game state is maintained). In the next and subsequent games, the symbol combination corresponding to the winning combination "BB" can be displayed on the effective line A. In the internal middle game state, the winning probability of the winning type "normal replay" is set higher (for example, 1 / 3.0) than the game state of the previous stage (immediately before), and as will be described later, the winning combination "increase bell" is set. Since the winning probability of "1" and the winning combination "Increase Bell 2" is high, it is possible to aim to display the symbol combination corresponding to the winning combination "BB" on the effective line A while suppressing the consumption of medals. Then, when the player displays the symbol combination corresponding to the winning combination "BB" on the effective line A, as shown in (7) of FIG. 6, the state transition means 312 sets the game state to the internal middle game. It shifts from the state to the bonus game state. Further, in the bonus game state, a predetermined number of medals (for example, bonus game state based on the winning combination "RBB1" = 351 sheets, bonus game state based on the winning combination "RBB2" and winning combination "RBB3" = 297 sheets, winning combination "CBB". When medals exceeding the bonus game state (81 medals) based on the above are paid out, the state transition means 312 shifts the game state from the bonus game state to the RT1 game state, as shown in FIG. 6 (8). However, as shown in (9) of FIG. 6, when the symbol combination corresponding to the winning combination "BB" is displayed on the effective line A in the game in which the winning combination "BB" is established, the internal middle game state is displayed. It directly transitions to the bonus game state without going through.

(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 divided, and the winning type to be the target of the lottery differs depending on each game state, and the presence or absence of non-winning differs depending on each game state. In FIG. 7, the winning area (winning type) assigned to each game state (RT1 game state, RT2 game state, RT3 game state, RT4 game state, internal medium game state, bonus game state) is represented by “○”. ing. Therefore, the winning area not marked with "○" indicates that it is not assigned to the gaming state. Each of the partitioned winning areas is associated with a predetermined winning range value (number of random numbers) indicating the winning range and the winning type, and the winning range values of all the winning areas assigned for each gaming state are totaled. Then, the total number of winning type lottery random numbers (65536) is obtained. Therefore, the probability that each winning type is determined is the value obtained by dividing the winning range value associated with the winning area by the total number of winning type lottery random numbers. The winning type lottery means 304 sequentially acquires the winning range value from a plurality of winning areas in the winning type lottery table based on the game 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 used as the lottery result. The lottery procedure can be applied to other lottery.

According to the winning type lottery table of FIG. 7, the winning type "normal replay" is associated with the winning area 1, and the winning combination "normal replay" is supported according to the winning of the winning type "normal replay". The symbol combination to be used can be displayed on the effective line A.

In addition, according to the winning type lottery table, a plurality of winning combinations may win in a duplicated 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. In this way, when a plurality of winning combinations are won in duplicate, a winning condition regarding which symbol combination corresponding to the winning combination is preferentially displayed on the effective 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, 130c for stopping the rotary reels in the order of the rotary reel 134a, the rotary reel 134b, and the rotary reel 134c is referred to as "batting order 1". Further, the operation of the stop switches 130a, 130b, 130c for stopping the rotary reels in the order of the rotary reel 134a, the rotary reel 134c, and the rotary reel 134b is referred to as "batting order 2". Further, the operation of the stop switches 130a, 130b, 130c for stopping the rotary reels in the order of the rotary reel 134b, the rotary reel 134a, and the rotary reel 134c is referred to as "batting order 3". Further, the operation of the stop switches 130a, 130b, 130c for stopping the rotary reels in the order of the rotary reel 134b, the rotary reel 134c, and the rotary reel 134a is referred to as "batting order 4". Further, the operation of the stop switches 130a, 130b, 130c for stopping the rotary reels in the order of the rotary reel 134c, the rotary reel 134a, and the rotary reel 134b is referred to as "batting order 5". Further, the operation of the stop switches 130a, 130b, 130c for stopping the rotary reels in the order of the rotary reel 134c, the rotary reel 134b, and the rotary reel 134a is referred to as "batting order 6".

For example, in the RT2 game state, when the winning type "transition replay 1" corresponding to the winning area 2 is determined by the winning type lottery and the operation is performed according to the batting order 1, the winning combination "transition" indicating the transition to the RT3 gaming state is performed. Stop control is performed so that the symbol combination corresponding to "Replay 4" is preferentially displayed on the effective line A. Further, when the operations in the batting order 2 to 6 are performed, the stop control is performed so that the symbol combination corresponding to the winning combination "normal replay" is preferentially displayed on the effective line A.

In this way, the winning type in which a plurality of winning combinations are duplicated is based on the type of symbol combination that can be displayed on the effective line A according to the operation order of the stop switches 130a, 130b, 130c by the player, or is won. When the winning combination is a small winning combination, FIG. 7 shows which symbol combination corresponding to the winning winning combination is preferentially displayed on the effective line A based on the number of medals paid out corresponding to the small winning 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, if any of the stop switches 130a, 130b, 130c is operated by the player during the rotation of the rotary reels 134a, 134b, 134c, the rotary reel 134a corresponding to the operated stop switches 130a, 130b, 130c , 134b, 134c, among the symbols existing in the pull-in range at the operation timing, the rotating reels 134a, 134b, 134c of the symbol combination corresponding to all the winning combinations that still have the possibility of winning. The symbol of 1 is subject to stop control, and the reel control means 306 puts any 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. Stop control to. In the present 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 types of winning combination symbol combinations 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 paid out corresponding to the winning combination (small combination), the small combination corresponding to the symbol combination displayed on the valid line A is paid out. The priority is set so that the higher the number, the higher the priority.

As described above, when the winning type "Transition Replay 1" is won, any of the overlapping winning combinations may be performed regardless of the timing at which the stop switches 130a, 130b, and 130c are pressed due to 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, 130c so as to stop any of the rotary reels 134a, 134b, 134c first, the symbol combination corresponding to the replay combination is displayed on the effective line A. Is possible, but the combination of symbols displayed will differ depending on the stop order.

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

In addition, when the winning type "selection bell left 1" corresponding to the winning area 14 is determined by the winning type lottery and the operation is performed according to the batting order 1, the symbol combination corresponding to the winning combination "increasing bell 1" with a large number of payouts is performed. Is stopped so that is preferentially displayed on the effective line A. As described above, the symbol combinations corresponding to the winning combination "increase bell 1" are arranged so that they can always be displayed on the effective line A by the stop control (see FIGS. 3 and 5). Further, when the operations in batting order 2 to 6 are performed, stop control is performed so that the symbol combination corresponding to any of the overlapping winning combination "maintenance bells" is preferentially displayed on the effective line A. .. However, even if the winning combination "maintenance bell" is won, the player is not always able to display the symbol combination corresponding to the winning combination "maintenance bell" on the effective line A. In this way, when the winning type "selection bell left 1" of the winning area 14 is won, when the player operates according to the batting order 1 which is the correct answer operation mode, the winning combination "increase bell 1" with 9 payouts is supported. The combination of symbols to be played can always be displayed on the valid line A (expected number of winnings = 9), and when operated according to the batting order 2 to 6, the winning combination of 3 payouts is avoided while avoiding the winning of the winning combination "Increase Bell 1". The symbol combination corresponding to the "maintenance bell" can be displayed on the effective line A with a probability of about 1/2, and the remaining winning combination should not be won with a probability of about 1/2 (missing). Can be done.

Here, in all the winning areas 14 to 25 of the winning type lottery table, one of the winning combinations "increase bell 1" and "increase bell 2" and one or more of the winning combinations "maintenance bell 1" to "maintenance bell 24". Winning combinations are duplicated (hereinafter, winning types "selection bell left 1", "selection bell left 2", "selection bell left 3", "selection bell left 4" in the winning areas 14 to 25. , "Selection bell 1", "Selection bell 2", "Selection bell 3", "Selection bell 4", "Selection bell right 1", "Selection bell right 2", "Selection bell right 3", The winning type "selection bell" may be abbreviated together with "selection bell right 4"), and the expected number of winnings is more than the winning combination "maintenance bell 1" to the winning combination "maintenance bell 24". Alternatively, the stop operation for winning the winning combination "Increase Bell 2" is set to differ depending on the winning area. The winning probabilities (number of placements) in the winning areas 14 to 25 are set to be equal. Since the player cannot usually know which winning type has been won, by providing the winning areas 14 to 25 as described above, the winning combination "increase bell 1" or the winning combination as the selected winning combination or It is extremely difficult to win the winning role "Increase Bell 2". However, even if the player wins a winning type in which the player's game profit differs depending on the operation order of the stop switches 130a, 130b, 130c, the player still wins the winning combination "Increase Bell 1" or the winning combination through the auxiliary effect. By grasping the correct operation mode that can win the "increase bell 2", the symbol combination corresponding to the winning combination "increase bell 1" or "increase bell 2" is displayed on the effective line A, and the auxiliary effect is not executed. It is possible to win more medals than in the non-AT production state.

In this way, by executing the auxiliary effect, the AT effect state (in this embodiment, the ART game state executed in parallel with the RT4 game state) in which medals are likely to increase according to the progress of the game and the auxiliary effect are performed. By not having it, it is possible to realize a non-AT effect state (mainly, RT1 game state, RT2 game state, RT3 game state) in which medals are easily reduced according to the progress of the game. Specifically, in the non-AT effect state in which the auxiliary effect is not performed, when the player operates the stop switch 130 in a random operation mode in the game in which the winning type "selection bell" is won, the specified number of inputs is "3". On the other hand, the expected number of acquired cards is about 2.75 (9 cards x 1/6 + about 3/2 cards x 5/6), and the number of medals tends to decrease as the game progresses. On the other hand, in the AT production state in which the auxiliary production is executed, the winning combination "increase bell 1" or the winning combination "increase bell 2" can be won in the game in which the winning type "selection bell" is won. The expected number of medals won is 9 for the number of input "3", and by adjusting the winning probability of the winning type "selection bell", it is possible to realize a game in which the number of medals is likely to increase as the game progresses.

(Transition of production state)
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) 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 is provided with a normal effect state and a chance effect state. When the non-AT effect state is executed, the execution frequency of the auxiliary effect is extremely lower than that of the AT effect state, and the auxiliary effect is hardly performed or the auxiliary effect is not performed at all, so that the number of medals that can be obtained is limited. To. The normal effect state is a game state corresponding to the initial state among the plurality of effect states managed by the sub-control board 202.

The state transition means 312 shifts the game state to the chance effect state at a predetermined opportunity in the normal effect state (1), and when the predetermined condition is satisfied while the chance effect state remains, for example, the predetermined number of games is digested. Then, it returns to the normal production state (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 either the normal production state or the chance production state, the lottery (production state lottery) determines whether or not to shift to the AT production 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 type is higher in the chance effect state than in the normal effect state. Therefore, the player desires to stay in the chance production state rather than the normal production 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 shifts the game state to the AT effect state.

(AT production state)
In the AT effect state, the correct answer operation mode is notified by the auxiliary effect, so that it is possible to acquire many medals while suppressing the consumption of medals. Therefore, the player can advance the game advantageously in the AT effect state as compared with the non-AT effect state.

Further, in the AT effect state, two AT effect states (normal AT effect state and chance AT effect state) are provided. In the normal AT effect state, the game progresses by managing the number of sets with a predetermined number of continuous games (for example, 50 games) as one set. When the effect state is set to the normal AT effect state, the state transition means 312 subtracts 1 from the number of sets stocked (held) and sets the number of continuous games to 50 games. Then, when the game of the continuous game number is completed, the state transition means 312 determines whether the number of sets is 0 (whether the number of sets is stocked), and if the number of sets is not 0, the stocked sets. The number is subtracted by 1 to continue the normal AT effect state (4). On the other hand, when the number of sets in stock is 0, the state transition means 312 ends the normal AT effect state and shifts 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 has elapsed, during which the number of sets in the normal AT effect state is added. Then, when the predetermined number of games is completed, the state transition means 312 shifts 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 production state as described above is biased, there is a concern that the shooting property will be excessively increased. Therefore, in order to comprehensively and uniformly determine whether or not the gaming state in which the medal acquisition performance is high is biased, judgment criteria such as an advantageous section ratio, a continuous bonus ratio, and a bonus ratio are set. The advantageous section ratio is the number of staying games, which 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 a value indicated by%. The continuous bonus ratio is a predetermined value. 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-class special bonus game, etc. in the standard aggregation period. Divided by the total number of payouts, it means the value indicated by%, and the bonus game is the number of medals paid out by the payout control means 310 based on the operation of the bonus game, etc. in the predetermined standard aggregation period. The number of bonuses paid out is divided by the total number of medals paid out by the payout control means 310, and the value is shown in%.

Here, the advantageous section refers to a section that is 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 staying games played in the AT effect state to the total number of games in the AT effect state and the non-AT effect state. In addition, 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 in an advantageous manner for the player may be arbitrarily set.

In addition, the accessory is a device for facilitating winning, and corresponds to a regular bonus (RB), a challenge bonus (CB), a single bonus (SB), and the like. In addition, among such characters, the regular bonus (RB) corresponds to the first-class special character. The regular big bonus (RBB) is such that the regular bonus (RB) operates continuously regardless of the display of the symbol combination indicating the winning form of the regular bonus (RB) which is the first type special character. The Challenge Big Bonus (CBB) is a continuous Challenge Bonus (CB) regardless of the display of the symbol combination indicating the winning form of the Challenge Bonus (CB), which is a Type 2 special character (one of the characters). It works with. Therefore, the continuous bonus ratio represents the ratio of the number of continuous bonuses paid out by the operation of the first-class special bonus to the total number of payouts in the predetermined standard aggregation period. Is to represent the ratio of the number of bonuses paid out by the operation of the bonuses to the total number of bonuses paid out in the predetermined standard aggregation period.

The standard aggregation period is a target period for accumulating the number of medals paid out by the payout control means 310. In the present embodiment, for example, there are two types: 6000 games, which is a finite value, and the entire period (hereinafter, referred to as "total cumulative total") after the slot machine 100 is installed in the game hall (hall). Therefore, as the continuous bonus ratio, the continuous bonus ratio of 6000 games and the continuous bonus ratio of the total total are derived, and as the bonus ratio, the bonus ratio of 6000 games and the total cumulative bonus ratio are derived. And derive. However, it goes without saying that an arbitrary number of games can be set as the standard aggregation period.

In order to obtain such an advantageous section ratio, continuous bonus ratio, and bonus ratio, the cumulative means 314 accumulates the total number of games, the number of staying games, the total number of payouts, the number of continuous bonus payouts, and the number of bonus payouts. .. At this time, counters are associated with each of the total number of games, the number of staying games, the total number of payouts, the number of continuous bonus payouts, and the number of bonus payouts. Specifically, when one game is started, the cumulative means 314 increments the total number of games 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 it is a game in the AT effect state, the stay game number counter indicating the number of stay games is incremented by 1. The update of the staying game number counter is started from the next game of the game (the game in which the transition process to the advantageous section is performed) that has won the AT effect state when the effect state is the non-AT effect state. However, if the AT production state is won based on the winning of the regular big bonus (RBB) or the challenge big bonus (CBB), the game (the game in which the transition process to the advantageous section is performed) in which the bonus is won is next. It starts from the game.

Further, when the medals are paid out in the game, the cumulative means 314 increments the total payout number counter indicating the total payout number by the number of payouts. Then, if the payout of the medal is based on the bonus, the bonus payout counter indicating the number of bonus payouts is incremented by the number of payouts, and the medal payout becomes the first-class special bonus. If it is based on this, the continuous bonus payout counter indicating the number of continuous bonus payouts is incremented by the number of payouts.

In addition, the total cumulative total can be counted only by such a counter, but the continuous bonus ratio and the bonus ratio must be applied not only to the total cumulative total but also to the standard aggregation period, here, a limited period such as 6000 games. Must be. Therefore, for example, 6000 games are evenly divided into 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 if the factor (divisor) of 6000 is used.

Specifically, when the medals are paid out in the game, the cumulative means 314 performs a process of updating the total payout counter, the continuous bonus payout counter, and the bonus payout counter up to 400 games, and reaches 400 games. , The total number of payouts, the number of continuous bonus payouts, and the number of bonus payouts are derived by adding up the 14 counters counted in the past. Then, the counter counted in the oldest game among the 14 counters is initialized, and the initialized counter is used to newly generate 400 game worth, total payout counter, continuous bonus payout counter, and bonus payout counter. Update. In this way, for every 400 games, the new game information for 400 games and the game information for the past 5600 games can be referred to, so that the total number of the latest 6000 games to be paid out, the number of continuous winnings to be paid out, and the winning combination It is possible to derive the number of items to be paid out. The counting by the counter is always executed regardless of the specified number or the set value. In this way, the total number of games, the number of staying games, the total number of payouts, the number of continuous bonus payouts, and the number of bonus payouts are accumulated.

Subsequently, the ratio deriving means 316 has an advantageous section ratio, a continuous bonus ratio, based on the total number of games, the number of staying games, the total number of payouts, the number of continuous bonus payouts, and the number of bonus payouts accumulated by the cumulative means 314. Derivation of the accessory ratio. Specifically, the ratio deriving means 316 divides the number of staying games by the total number of games, converts it into% to derive the advantageous section ratio, and divides the total number of continuous bonus payouts by the total total number of payouts. ,% Convert to derive the total cumulative bonus ratio, divide the total cumulative number of bonus payouts by the total cumulative payouts, and convert to% to derive the total cumulative bonus ratio. Further, the ratio derivation means 316 divides the number of continuous bonuses paid out in 6000 games by the total number of payouts in 6000 games for every 400 games, and converts them into% to derive the continuous bonuses ratio in 6000 games. The number of bonuses paid out is divided by the total number of payouts of 6000 games, and converted into% to derive the bonus ratio of 6000 games.

Next, the ratio display means 318 has an advantageous section ratio derived by the ratio derivation means 316, a continuous bonus ratio of 6000 games, a bonus ratio of 6000 games, and a total continuous bonus ratio based on a predetermined display command. , The total cumulative bonus ratio is displayed on the ratio display unit 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 consisting of seven segments capable of representing decimal Arabic numerals and a dot segment (DP) located at the lower right of the segments. Then, when incorporating the main control board 200 into the slot machine 100, as shown in FIG. 9B, the main control board 200 is housed in the board case 172, and the main control board 200 is placed in the front portion 172a of the board case 172. Fix it with screws 174 from the back. A transmission window 172b that allows the ratio display unit 160 to be visually recognized is provided at a position corresponding to the ratio display unit 160 on 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 172b with the front upper door 104 open. Instead of the transparent window 172b, the entire substrate case 172 may be formed of a transparent or semi-transparent material.

Here, only the four 7 segments that make up the ratio display unit 160, the advantageous section ratio, the continuous character ratio of 6000 games, the character ratio of 6000 games, the continuous character ratio of the total cumulative total, and the character ratio of the total cumulative total. In order to display the five game information such as, an identifier is associated with each ratio, and the identifier and each ratio are sequentially displayed on the ratio display unit 160. Each ratio is shown in the range of 0 to 99. Therefore, of the four 7 segments, the two 7 segments located on the left side indicate the identifier, and the two 7 segments located on the right side indicate the 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 simultaneously displays the identifier "7U" corresponding to the advantageous section ratio and the ratio, for example, "70"%. indicate. The ratio display means 318 separates the identifier and the ratio by lighting the dot segment of the second 7-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 has an identifier "6Y" corresponding to the continuous bonus ratio of 6000 games and its ratio. "60"% and "60"% are displayed at once. Then, each time a predetermined time elapses, a combination of the identifier "7Y" corresponding to the accessory ratio of 6000 games and the ratio "70"% as shown in FIG. 10C is shown in FIG. A combination of the identifier "6A" corresponding to the total cumulative continuous bonus ratio as shown in (d) and the ratio "60"%, and the total cumulative bonus as shown in FIG. 10 (e). The combination of the identifier "7A" corresponding to the object ratio and the ratio "70"% is sequentially displayed. Further, as shown in FIG. 10 (e), in a state where the combination of the identifier "7A" corresponding to the total cumulative bonus ratio and the ratio "70"% is displayed, the predetermined time is further set. After that, the identifier “7U” corresponding to the advantageous section ratio and the ratio “70”% shown in FIG. 10A are displayed again, and every time a predetermined time elapses thereafter. , Advantageous section ratio, continuous bonus ratio of 6000 games, bonus ratio of 6000 games, continuous bonus ratio of total cumulative, and total cumulative bonus ratio, the display is switched in this order.

In this section, an example in which the identifier and the ratio are simultaneously shown in the four 7 segments has been described, but the identifier and the ratio can be switched and displayed by using only the two 7 segments. In this case, the ratio display means 318 displays, for example, "7U"-> "70"-> "6Y"-> "60"-> "7Y"-> "70"-> "70" every time the predetermined time elapses in the ratio display unit 160. The display is switched in the order of "6A"-> "60"-> "7A"-> "70".

In addition, the ratio display means 318 replaces the ratio display unit 160 of the main control board 200 with an identifier and a ratio on the existing display units (main credit display unit 152 and main payout display unit 154) corresponding to the four 7 segments. Can also be switched and displayed. In this case, after the result of one game is notified, by the start of the next game, the front upper door 104 is opened, and in that state, an operation of setting or changing an existing switch, for example, a set value is executed. By operating the switch, the identifier corresponding to the advantageous section ratio and its ratio are displayed, and after that, every time a predetermined time elapses, the advantageous section ratio → the continuous character ratio of 6000 games → the character ratio of 6000 games → The display will be switched repeatedly in the order of the total cumulative bonus ratio → the total cumulative bonus ratio. In addition, the ratio display means 318 displays the advantageous section ratio, the continuous bonus ratio of 6000 games, the bonus ratio of 6000 games, the continuous bonus ratio of the total total, and the bonus ratio of the total cumulative on the existing display unit. Even while there is a change in the state of the slot machine 100 such as inserting a medal, the display is deleted.

Through such a ratio display unit 160 or an existing display unit, the manager can use the advantageous section ratio, the continuous character ratio of 6000 games, the character ratio of 6000 games, the continuous character ratio of the total total, and the total character of the total. Game information such as 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 appropriate ranges include, for example, an advantageous section ratio <70%, a continuous character ratio of 6000 games <60%, a character ratio of 6000 games <70%, a total cumulative continuous character ratio <60%, and a total cumulative total. The accessory ratio is set to <70%. If it deviates from such an appropriate range, the ratio display means 318 may blink each segment of the ratio display unit 160 with respect to the target ratio, for example, at a cycle of 0.6 sec. Such a blinking display enables the administrator to quickly grasp the identifiers that deviate from the appropriate range and their ratios.

By the way, as described above, the ratio deriving means 316 divides the number of staying games by the total number of games to derive the advantageous section ratio, and divides the total number of continuous bonus payouts by the total total number of payouts. The total number of consecutive bonuses paid out is derived, and the total number of bonuses paid out is divided by the total number of cumulative bonuses paid out to derive the total number of bonuses paid out. However, the processing capacity of the main CPU 200a on the main control board 200 is low, and the division instructions that can be used by the main CPU 200a are limited in the range of numerical values that are divisors and divisors. For example, in the DIV instruction for executing division, which is prepared in advance as an operation instruction in the main CPU 200a, the numerical range of both the divisor and the divisor is limited to 2 bytes, that is, only the range from 0 to 65535 is handled. I can't. On the other hand, it is assumed that the total number of games will be, for example, 175,000 games or more. Therefore, the numerical range is exceeded, and the DIV instruction cannot be simply used. In this case, a program that repeats multiplication and subtraction must be separately prepared in the same way as a person performs division by hand, which causes an increase in processing load. Therefore, in the present embodiment, it is an object 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, accessory ratio) will be described, but first, the parts common to the plurality of processes will be described in detail. In the present embodiment, the values finally converted into% 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 required for the result of division. Further, in the present embodiment, the value after the decimal point when converted to% is rounded down. This means that if only two digits after the decimal point can be derived from the result of division, operations after three digits after the decimal point are not required. Therefore, in the present embodiment, a predetermined multiplicand (here, 100) is multiplied in order to carry the division result by two digits. Here, since only two decimal places are required, an example of multiplying by "100" as a multiplicand was given, but if three decimal places are required, multiply by "1000" as a multiplicand, etc., depending on the required number of digits. Can be changed.

Further, here, the “accessory ratio” will be described as the target 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 ratio is derived by dividing the number of bonus payouts by the total number of payouts and converting it to%. Such a "% conversion" point corresponds to multiplying the multiplicand "100". Therefore, it can be expressed by the formula: bonus ratio = number of bonus payouts ÷ total number of payouts × 100. However, since the number of bonuses paid out ≤ the total number of payouts, unless the number of bonuses paid out = the total number of payouts, the value after the decimal point is always the value at the time of the number of bonuses paid out ÷ the total number of payouts in this formula. Therefore, for example, the main CPU 200a cannot perform calculation.

Therefore, the calculation order is changed, and the calculation is performed in the order of the bonus ratio = the number of bonus payouts x 100 ÷ the total number of payouts (first, multiply by the multiplicand, and then divide by the total number of payouts). By doing so, it is possible to complete the operation result only with an integer without performing the operation 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 showing a first calculation example of the accessory ratio, and FIG. 12 is an explanatory diagram for explaining a specific processing of the calculation. Here, assuming that the number of bonuses paid out is "7123" and the total number of bonuses paid out is "10000", the bonus ratio is derived. Here, by replacing division with subtraction, division of a number exceeding the numerical range (0 to 65535) is realized.

First, the ratio deriving means 316 determines whether or not the number of bonuses paid out is larger than the total number of payouts (S1). As a result, if it is determined that the number of bonuses paid out is larger than the total number of payouts (YES in S1), it is considered that the number of bonuses paid out or the total number of payouts is not an appropriate value, and the result is that the bonus ratio is abnormal. It is derived and the arithmetic processing is terminated (S2). If it is determined that the number of bonuses paid out is equal to or less than the total number of payouts (NO in S1), the ratio derivation means 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 the medals have not been paid out yet (YES in S3), it is determined that the bonus 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 number of bonus payouts and the total number of payouts are equal (S5). As a result, if it is determined that the number of bonuses paid out and the total number of bonuses paid out are equal (YES in S5), it is determined that the bonus ratio is 99%, and the calculation process is terminated (S6). As described above, in the present embodiment, when the number of bonuses paid out and the total number of bonuses paid out are equal, the bonus ratio is originally 100%, but is expressed as 99%. By doing so, it is possible to express all the accessory ratios in two digits.

If it is determined that the number of bonuses paid out and the total number of payouts are not equal (NO in S5), the ratio derivation means 316 multiplies the number of bonuses paid out "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 means 316 updates the dividend by subtracting the total payout number “10000” as the divisor from the division (S9), and adds 1 to the quotient (S10). Adding 1 to the quotient is equivalent to adding 1% to the bonus ratio. Then, the ratio deriving means 316 determines whether or not the updated division number is less than 0 (S11). As a result, if it is determined that the updated division number 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 division number is 0 or more (NO in S11), it is assumed that the accessory ratio has not been reached yet, and the process from the subtraction step S9 is repeated.

The repetition of the process 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 divisor (total payout number) "10000" from the divisor "712300" obtained by multiplying the accessory payout number "7123" by the multiplicand "100" to obtain the divisor " Update to "702300". Then, in the first addition step S10, the ratio deriving means 316 adds "1" to the quotient "-1" and updates the quotient to "0". When the same process is repeated, in the 72nd subtraction step S9, the divisor (total payout number) "10000" is subtracted from the division number "2300", the division number is updated 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 divisor becomes negative (<0), the arithmetic processing is completed, and the accessory ratio becomes the quotient “71” at that time. The quotient "71" corresponds to the number of subtractions (72nd-1) before the division (subtraction result) becomes negative (when the division is "2300"). Since this corresponds to the integer part of 71.23%, which is the result of dividing the number of bonuses paid out "7123" by the total number of payouts "10000", it can be understood that such an operation is correct.

In addition, when the division number becomes negative, it means that the subtraction is performed once more than the number of times corresponding to the original accessory ratio. For example, in FIG. 12, the number of times “72” actually subtracted is one more than “71” times, which corresponds to the original accessory ratio “71”%. Therefore, in order to use the quotient at the time when the divisor becomes negative as it is as the accessory ratio, "-1" is set as the initial value of the quotient as in the initialization step S8.

According to the first calculation example, division can be realized only by simple operations such as addition, subtraction, and multiplication, and by only integers. Here, it is sufficient to repeat the process from the subtraction step S9 at least 100 times. Further, on the premise that the decimal point of the accessory ratio is rounded down, no error occurs, so that the accessory ratio can be accurately derived.

In the above, it is assumed that the decimal point of the accessory ratio is rounded down, but not limited to this case, the final divisor value that becomes negative when the decimal point of the accessory ratio is rounded off (here, "" If the absolute value of -7700 ") is greater than 1/2 of the divisor (total number of payouts, here" 10000 "), it is rounded down, and if it is 1/2 or less, it is rounded up.

(Second calculation example)
In the first calculation example, the divisor is subtracted from the repeated divisor a number of times corresponding to the accessory ratio (more accurately, +1 time). Then, the subtraction process will be executed up to 100 times. In the second calculation example, the number of subtraction processes is reduced by multiplying the divisor by an integer and subtracting. For example, when the number of bonuses paid out is "7123" and the total number of payouts is "10000", the divisor "10000" is not simply subtracted from the division "712300", and the integer "10" is added to the divisor "10000". By subtracting the multiplied "100,000", "7" corresponding to the second digit of the accessory ratio can be derived. Further, by subtracting the original divisor "10000" from the updated (subtracted) divisor, "1" corresponding to the first digit of the accessory ratio can be derived. By multiplying the divisor by an integer in this way, it is possible to reduce the subtraction process to at most 20 times here.

However, since the main CPU 200a performs the calculation in a decimal number, the number "2" corresponding to the carry in the decimal number is used here instead of the number "10" corresponding to the carry in the decimal number. Therefore, here, the number obtained by multiplying the divisor "10000" by the predetermined integer "64 (2 to the 6th power)", which is a power of 2, is subtracted from the division "712300", and thereafter, the integer is "32 ( 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 ( Change in the order of 2 to the 0th power), multiply by the divisor, and subtract from the dividend. Here, the integer to be multiplied by the divisor starts from 64, which is a power of 2, because the accessory ratio falls within the range of 0 to 99, so a numerical value of "128 (2 to the 7th power)" or more is used. This is because there is no need to subtract.

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

If it is determined that the number of bonuses paid out and the total number of payouts are not equal (NO in S25), the ratio derivation means 316 multiplies the number of bonuses paid out "7123" by the multiplicand "100" and holds it as a division (variable). At the same time (S27), the integer (variable) is initialized to "64" (S28), the total payout number "10000" is set to the divisor (variable), and the integer "64" is multiplied (S29) to obtain the quotient (variable). ) Is initialized to "0" (S30). Subsequently, the ratio deriving means 316 determines whether or not the divisor is equal to or greater than the divisor (S31). As a result, if it is determined that the divisor is equal to or greater than the divisor (YES in S31), the divisor is subtracted from the divisor to update the divisor (S32), and an integer is added to the quotient (S33). In this way, the accessory ratio corresponding to the integer is added to the quotient. In the second calculation example, since the calculation process is performed using an integer that is a power of 2, it is sufficient to execute the subtraction step S32 and the addition step S33 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 means 316 divides the divisor by "2" to update the divisor (S34), and divides the integer by "2" to update the integer (S35). In this way, the preparation for the next subtraction step S32 is completed. The division of "2" in the division steps S34 and S35 is a one-bit shift to the right of the binary number (LSB is deleted in the binary number, each bit is shifted by one digit (1 bit shift), and 0 is inserted in the MSB. Since it can be realized by (corresponding to "÷ 2", also called a logical shift), there is no need to use the DIV instruction.

Then, the ratio deriving means 316 determines whether or not the updated integer is less than 1 (S36). As a result, if the updated integer is less than 1 (to be exact, 1/2 = 0.5, and the decimal point is truncated to 0), that is, the subtraction step S32 with the integer being 1. If is performed (YES in S36), the arithmetic processing is terminated. Therefore, the quotient at this point becomes the accessory ratio as it is. Further, if it is determined that the updated integer is 1 or more (NO in S36), it is assumed that the accessory ratio has not been reached yet, and the process from the determination step S31 is repeated.

The repetition of the process from the determination step S31 will be described with reference to FIG. If it is determined in the first determination step S31 that the division ≥ the divisor, the ratio deriving means 316 subtracts the divisor "64 x 10000" from the division "712300" to update the division to "72300" and the quotient "72300". Add "64" to "0" to update the quotient to "64 (1000000B in binary)". In the second to fourth determination steps S31, since the divisor <division, the subtraction step S32 and the addition step S33 are not executed. If it is determined in the fifth determination step S31 that the division ≥ the divisor, the ratio deriving means 316 subtracts the divisor "4 x 10000" from the division "72300" to update the division to "32300" and the quotient "32300". Add "4" to "64" to update the quotient to "68 (1000100B in binary)". Similarly, if it is determined in the sixth determination step S31 that the division ≥ the divisor, the ratio deriving means 316 subtracts the divisor "2 x 10000" from the division "32300" and updates the division to "12300". , Add "2" to the quotient "68" to update the quotient to "70 (1000110B in binary)". If it is determined in the seventh determination step S31 that the division ≥ the divisor, the ratio deriving means 316 subtracts the divisor "1 x 10000" from the division "12300" to update the division to "2300" and the quotient "2300". Add "1" to "70" to update the quotient to "71 (1000111B in binary)".

When the process from the determination step S31 is repeated seven times, the integer after the decimal point is truncated to 0 (<1), so that the arithmetic processing is completed and the accessory ratio is the quotient "71" at that time. It becomes. Since this corresponds to the integer part of 71.23%, which is the result of dividing the number of bonuses paid out "7123" by the total number of payouts "10000" and converting it into%, it can be understood that such an operation is correct.

According to the second calculation example, division can be realized only by simple operations such as addition, subtraction, and multiplication, and by only integers. Further, here, since it is sufficient to repeat the process from the determination step S31 seven times, the arithmetic process can be performed quickly. Further, assuming that the value after the decimal point of the accessory ratio is rounded down, no error occurs, so that the accessory ratio can be accurately derived.

Also here, it is assumed that the decimal point of the accessory ratio is rounded down, but not limited to this case, when rounding off the decimal point of the accessory ratio, the process from the determination step S31 is repeated eight times, and the eighth time. If it is determined that the divisor ≥ the divisor in the determination step S31, it can be realized by adding 1 to the quotient.

(Third calculation example)
In the third calculation example, even if the divisor or divisor exceeds 2 bytes, it is kept within 2 bytes by dividing both by the same integer, and the DIV instruction available in the main CPU 200a is used.

However, since the main CPU 200a performs the calculation in a decimal number, the number "2" corresponding to the carry in the decimal number is used instead of the number "10" corresponding to the carry in the decimal number. Therefore, here, the division number "712300" and the divisor "10000" are sequentially divided by an integer "2", and if the division number 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 a specific processing of the calculation. Here, as in the first and second calculation examples, the bonus ratio is derived assuming that the number of bonuses paid out is “7123” and the total number of bonuses paid out is “10000”. Since steps S41 to S46 are substantially the same as steps S1 to S6 of the first calculation example, the description thereof will be omitted here.

If it is determined that the number of bonuses paid out and the total number of payouts are not equal (NO in S45), the ratio derivation means 316 multiplies the number of bonuses paid out "7123" by the multiplicand "100" and holds it as a division (variable). At the same time (S47), the total payout number "10000" is set as a divisor (variable) (S48). Subsequently, the ratio deriving means 316 determines whether or not the divisor or divisor is outside the predetermined numerical range (65536 or more in this case), that is, whether or not it is outside the numerical range that can be used by the DIV instruction (S49). .. As a result, if it is determined that the divisor or divisor is out of the predetermined numerical range (YES in S49), the divisor is divided by "2" to update the divisor (S50), and the divisor is divided by "2". The divisor is updated (S51), and the process from the determination step S49 is repeated. In this way, the divisor and the divisor can be reduced until both fall within a predetermined numerical range (until less than 65536). Since both are repeatedly divided by the same integer "2" the same number of times, the ratio between the divisor and the divisor does not change. Here, too, the division of "2" in the division steps S50 and S51 can be realized by shifting the binary number to the right by 1 bit, so that it is not necessary to use the DIV instruction.

Then, when the divisor and the divisor fall within a predetermined numerical range (here, when it is less than 65536) (NO in S49), the ratio deriving means 316 executes the DIV instruction for dividing 2 bytes by 2 bytes (S52). The result is used as the accessory ratio.

The repetition of the process from the determination step S49 will be described with reference to FIG. If it is determined in the first determination step S49 that the divisor or divisor is 65536 or more, the ratio deriving means 316 divides the divisor "712300" by an integer "2" and updates the divisor to "356150". , The divisor "10000" is divided by the integer "2" to update the divisor to "5000". Similarly, in the second determination step S49, the ratio deriving means 316 divides the division "356150" by the integer "2" to update the division to "178075" and the divisor "5000" with the integer "2". Divide and update the divisor to "2500", and in the third determination step S49, divide the divisor "178075" by the integer "2" to update the divisor to "89037" and the divisor "2500" to the integer "28037". Divide by "2" to update the division to "1250", and in the fourth determination step S49, divide the division "89037" by the integer "2" to update the division to "44518" and the divisor "1250". Is divided by the integer "2" to update the dividend to "625". Then, since both the divisor "44518" and the divisor "625" fall within the predetermined numerical range (because it is less than 66536), the ratio deriving means 316 executes the DIV instruction for dividing 2 bytes by 2 bytes. The accessory ratio "71" can be derived. Since this corresponds to the integer part of 71.23%, which is the result of dividing the number of bonuses paid out "7123" by the total number of payouts "10000" and converting it into%, it can be understood that such an operation is correct.

According to the third calculation example, division can be realized only by simple operations such as multiplication, division by DIV instruction, and bit shift, and division can be realized by only integers, and the processing load can be reduced.

Here, since the divisor and the resolution of the divisor are reduced to reduce the number, an error may occur in the calculation result (role ratio). However, since such an error is for one bit when one of them becomes less than 65535, the case where the error is maximum, that is, the divisor is "32768 (10000000B in binary)" and the divisor is "327". The divisor (denominator) of 1 bit when expressed in binary (101000111B) is 1 bit. Therefore, the error is 32768/327-32768/328 = 0.306%. Therefore, due to such an error, the value after the decimal point is changed. As a result of truncation, the bonus ratio may be reduced by 1%, but it is less than 2%, which is very unlikely, so there is no problem.

Hereinafter, specific processing on the main control board 200 and the sub control board 202 will be described with reference to the flowchart.

(Main processing of main control board 200)
FIG. 17 is a flowchart showing the main processing of the main control board 200. Here, first, the outline of one game after initialization will be described along with the main processing of the main control board 200, and then the details of each processing will be described. Further, here, the processing related to the features of the present embodiment will be described in detail, and the description of the configuration unrelated to the features of the present embodiment will be omitted. Further, although detailed description is omitted, when each process is executed, the switches (bet switch 126, start switch 128, stop switch 130a, 130b, 130c) used in each process are activated 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 the power is turned on, the initialization means 300 executes the initialization process in preparation for the start of the game. The initialization means 300 generates backup data at any time while the power is turned on, and holds the backup data in the main RAM 200c. Therefore, even if an unexpected power failure occurs, in this initialization process, the retained backup data can be used to restore the state before the power failure. For example, even if an unexpected power failure occurs during the rotation of the rotary reels 134a, 134b, 134c, the rotation of the rotary reels 134a, 134b, 134c is started again after the return operation. Therefore, in the initialization process, basically, the main RAM 200c is not initialized (RAM clear).

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

(Step S300)
Next, the winning type lottery means 304 activates the game start operation for the start switch 128, and shifts to the operation waiting state of the start switch 128. Here, the winning type lottery means 304 is at the time when the start switch 128 is operated from the winning type lottery random numbers updated by the random number generator 200d of the main control board 200 in response to the operation of the start switch 128 by the player. Acquire the winning type lottery random number of 1. Then, the winning type lottery means 304 determines one winning type lottery table corresponding to the currently set game 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 winning type lottery table, and the winning type or non-winning of the determined winning area is determined as the lottery result. Further, the command determining means 320 generates a winning type command including information on the lottery result (winning type or unwinning) of the winning type lottery, the game state, and the like after the lottery result is determined according to the operation of the start switch 128. Then, the command transmitting means 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 means 306 drives the stepping motor 262 to rotate the rotary reels 134a, 134b, 134c. In this reel rotation process, when a predetermined time (for example, 4.1 seconds) has elapsed from the start of rotation of the rotary reels 134a, 134b, 134c in the previous game (wait), the rotary reels 134a, 134b, 134b, in the game. The rotation of 134c is started, and when all of the rotary reel 134a, the rotary reel 134b, and the rotary reel 134c have reached constant speed rotation, the process is transferred to step S500.

(Step S500)
Subsequently, when the reel control means 306 activates the stop switches 130a, 130b, 130c and receives the operation of the stop switches 130a, 130b, 130c by the player, any of the rotary reels 134a, 134b, 134c corresponding to the operation is received. Or) is stopped and controlled. Further, when any one of the stop switches 130a, 130b, and 130c is operated, the command determining means 320 is a stop command (first stop command, second stop command, second) indicating information on the stopped switches 130a, 130b, 130c that have been operated. The stop command and the third stop command) are generated each time the operation is performed, and the command transmission means 322 sequentially transmits the generated stop commands to the sub-control board 202.

(Step S600)
Next, the determination means 308 determines which predetermined combination the symbol combination displayed on the effective line A shown in FIG. 3B corresponds to, and the game state is determined according to the symbol combination. Performs various processes required for changes and replays. Further, the command determining means 320 generates a winning command including the number of medals to be paid out when the symbol combination displayed on the effective line A and the symbol combination corresponding to the small winning combination is displayed on the effective line A. , The command transmitting means 322 transmits the generated winning command to the sub-control board 202.

(Step S700)
Subsequently, the payout control means 310 executes a medal payout process corresponding to the small winning combination when, for example, a symbol combination corresponding to the small winning combination is displayed on the effective line A based on the determination result in step S600. , When the symbol combination corresponding to the replay combination is displayed on the effective line A, the process for betting the next game is automatically executed. Further, when the predetermined number of medals are paid out in the bonus game state, the state transition means 312 returns the game state to the game state before the transition from the bonus game state to the bonus game state, and corresponds to the game state. Set the winning type lottery table. In this way, the payout control means 310 executes various processes corresponding to the symbol combinations displayed on the effective line A, and ends the one game. Further, the cumulative means 314 accumulates the total number of games, the number of staying games, the total number of payouts, the number of continuous bonus payouts, and the number of bonus payouts, and the ratio derivation means 316 is the total number of games, the number of staying games, and the total number of payouts. , The advantageous section ratio, the continuous bonus ratio, and the bonus ratio are derived based on the number of continuous bonus payouts and the number of bonus payouts. Further, when the medal payout process is performed, the command determination means 320 generates a payout command indicating that the payout process has been performed, and the command transmission means 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. After that, steps S200 to S700 are repeated.

Further, when the ratio display means 318 receives a predetermined display command as the interruption process, as described with reference to FIG. 10, the ratio derivation means 316 derives the advantageous section ratio, the continuous bonus ratio of 6000 games, and the ratio. The character ratio of 6000 games, the total cumulative character ratio, and the total cumulative character ratio are displayed on the ratio display unit 160.

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

(Step S701)
First, the cumulative means 314 increments the total number of games 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 it is a game in the AT effect state, the stay game number counter indicating the number of stay games is incremented by 1. Further, when the medals are paid out in the game, the cumulative means 314 increments the total payout number counter indicating the total payout number by the number of payouts. Then, if the payout of the medal is based on the bonus, the bonus payout counter indicating the number of bonus payouts is incremented by the number of payouts, and the medal payout becomes the first-class special bonus. If it is based on this, the continuous bonus payout counter indicating the number of continuous bonus 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 continuous bonus payouts, and the number of bonus payouts are accumulated.

(Step S702)
Subsequently, the ratio deriving means 316 divides the number of staying games by the total number of games based on the total number of games and the number of staying games accumulated by the cumulative means 314, and converts them into% to derive the advantageous section ratio.

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

(Step S704)
If it is determined in step S703 that 400 games have passed, the ratio deriving means 316 refers to the newly accumulated game information for 400 games and the game information for the past 5600 games, and is the latest. Derivation of the continuous bonus ratio of 6000 games.

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

(Step S706)
Next, the ratio deriving means 316 refers to all the past game information including the newly accumulated game information for 400 games, and derives the total cumulative continuous bonus ratio.

(Step S707)
Subsequently, the ratio deriving means 316 refers to all the past game information including the newly accumulated game information for 400 games, and derives the total cumulative bonus ratio.
