Description

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

A slot machine as a gaming machine is provided with a plurality of gaming states and effect states in which the degree of advantage (game profit) of the player is different when 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 the activated line to shift from a normal game state to a bonus game state in which a player can easily obtain a medal.

Further, in the slot machine, the game profit is determined by lottery based on a predetermined trigger such as operation of a start switch. For example, a technique is known in which a number is determined for each lottery target, the number of each lottery target is sequentially added (subtracted) to a random number value, and when an overflow occurs, the lottery target is won (for example, Patent Document 1).

JP, 2005-119737, A

The slot machine is provided with a plurality of game states in which the degree of advantage (game profit) of the player is different as the game progresses. For example, a winning combination (hereinafter referred to as a selected winning classification) in which a winning combination with a large gaming profit (hereinafter, referred to as a correct winning combination) and another winning combination with a smaller gaming profit than the correct answer (hereinafter referred to as an incorrect winning combination) are duplicated By being notified of the operation mode of the stop switch (hereinafter referred to as the correct answer operation mode) which is the winning condition of the correct winning combination when the player is won (hereinafter, the operation mode which becomes the winning condition of such a predetermined winning combination) The effect that notifies the player is simply referred to as an auxiliary effect), and the player can easily display the symbol combination corresponding to the correct answer on the activated line, so-called AT effect state in which AT (assist time) is executed. Some slot machines are equipped with.

In such an AT effect state, the average number of coins expected per unit game (hereinafter, the expected number of coins per unit game (base)) when the player operates in the correct operation mode is set. On the other hand, there is a demand to reduce the expected number of coins to be acquired per unit game when the player does not perform an operation in the correct operation mode, while increasing the number. Therefore, when the player does not perform the operation in the correct operation mode, the symbols may be arranged so that the stop control in which the incorrect combination is not necessarily displayed on the activated line A is performed while avoiding the winning of the correct combination. Conceivable. However, if the player is able to specify the incorrect solution during the operation, it is possible to win the incorrect solution with a higher probability than when the player randomly operates. Therefore, by providing a plurality of fraudulent winning combinations that are exclusively won by the player's operation and arranging them in the winning areas as different winning types, the unit game when the player does not operate in the correct operation mode It is possible to equalize the expected number of sheets to be acquired. In this way, a plurality of winning type pairs (hereinafter, referred to as correct answer pairs) are generated for each of the same correct answers, each including an incorrect answer that is exclusively won.

In addition, in order to adjust the expected number of coins to be won per unit game, in a predetermined game state, stop control when winning in the winning area in which the selected winning type is arranged is set to the correct answer regardless of the operation mode of the player. The corresponding symbol combination may be changed to be displayed on the activated line A. However, if the stop control for all the selected winning types is changed, the expected number of coins to be won per unit game becomes excessively high.

The present invention has been made in view of the above problems, and an object thereof is to provide a gaming machine capable of adjusting the expected number of coins to be won per unit game.

In order to solve the above problems, the gaming machine of the present invention is a winning type in which a correct combination and an incorrect combination different from the correct combination overlap based on the operation of the start switch, and a predetermined correct operation for the stop switch. Based on the operation of the start switch and the winning type lottery means for determining one of a plurality of winning types including the selected winning type set as the winning condition of the correct winning combination by the operation according to the aspect, the operation of the start switch, a plurality of types According to the operation of the stop switch corresponding to the spinning reel, the rotation control is performed on a plurality of reels in which the respective symbols are arranged, and the operated stop switch is supported based on the lottery result of the winning type lottery means. Reel control means for controlling the respective reels to stop, an auxiliary effect notification means for executing an auxiliary effect for notifying the correct operation mode at the time of winning the selection winning type, and an AT for causing the auxiliary effect informing means to execute the auxiliary effect. Production state control means for shifting to any of a plurality of types of production states including production state, non-internal game state, bonus internal game state transitioned based on winning a bonus combination in the non-internal game state, And a gaming state control means for shifting to one of the bonus operating game states that shifts based on the winning of the bonus combination, and the reel control means is configured to select a specific selection winning type by the winning type lottery. When it is determined, the stop control is changed so that the probability of winning the correct winning combination is higher in the bonus internal game state than in the non-internal game state, and the predetermined winning different from the specific selection win type When the type is determined, the same stop control is performed in the non-internal gaming state and the bonus internal gaming state, and in the bonus operating gaming state, the incorrect answer is included but the correct answer is not included. The relationship between the first probability that the correct answer winning type is determined and the specific selection winning type is determined by the winning type lottery, and the second probability that the incorrect answer winning type is determined in the gaming state during bonus operation is: The first probability <the second probability.

According to the present invention, it is possible to adjust the expected acquisition number per unit game.

The main CPU 200a executes various processes based on the received detection signal.

The initialization unit 300 executes an initialization process in the main control board 200. The betting means 302 bets a medal for use in a game. Based on the operation of the start switch 118, the winning type lottery means 304 carries out a winning type lottery for determining whether or not the winning combination is won, more specifically, the winning type including the winning combination.

The reel control means 306 controls the rotation of the left reel 110a, the middle reel 110b, and the right reel 110c according to the operation of the start switch 118, and corresponds to the rotating left reel 110a, middle reel 110b, and right reel 110c, respectively. According to the operation of the stop switches 120a, 120b, 120c, the corresponding left reel 110a, middle reel 110b, and right reel 110c are stopped and controlled.

A reel drive controller 150 is connected to the main control board 200. The reel drive control unit 150 drives the stepping motor 152 based on the rotation start signals of the left reel 110a, the middle reel 110b, and the right reel 110c transmitted from the reel control means 306 in response to the operation signal of the start switch 118. To do. Further, the reel drive control unit 150 detects the stop signals of the left reel 110a, the middle reel 110b, and the right reel 110c and the detection of the rotation position detection circuit 154, which are transmitted from the reel control means 306 in response to the operation signal of the stop switch 120. The driving of the stepping motor 152 is stopped based on the signal.

The determination means 308 determines whether or not the symbol combination corresponding to the winning combination is displayed on the activated line A. Here, displaying the symbol combination corresponding to the winning combination on the activated line A may be simply referred to as winning. The payout control means 310 pays out the medals in the number corresponding to the winning combination based on that the symbol combination corresponding to the winning combination is displayed on the activated line A (winning). Further, a medal payout device 142 is connected to the main control board 200, and the payout control means 310 ejects medals while counting the number of paid out medals.

The game state control means 312 refers to the result of the winning type lottery or the determination result of the determination means 308 and shifts the game state to one of a plurality of types of game states. Further, the effect state control unit 314 refers to the result of the winning type lottery, the determination result of the determination unit 308, and the game state transition information, and shifts the effect state to one of a plurality of types of effect states.

The command transmission means 316 is a command relating to the game accompanying the operations of the bet means 302, the winning type lottery means 304, the reel control means 306, the determination means 308, the payout control means 310, the game state control means 312, the effect state control means 314, etc. Are sequentially determined, and the determined commands are sequentially transmitted to the sub control board 202.

Further, the main control board 200 is provided with a random number generator (random number generating means) 200d. The random number generator 200d sequentially increments the count value, loops within a predetermined numerical value range, and extracts the count value at a predetermined time point to obtain a random number. The random number generated by the random number generator 200d of the main control board 200 (hereinafter referred to as a winning type lottery random number) is used for determining the winning type by the gaming profit to be given to the player, for example, the winning type lottery means 304. ..

(Sub-control board 202)
The sub-control board 202, like the main control board 200, has various semiconductor integrated circuits including a sub-CPU 202a that is a central processing unit, a sub-ROM 202b that stores programs and the like, a sub-RAM 202c that functions as a work area, and the like. Based on the command from the main control board 200, the effect is particularly controlled. Further, a backup power supply (not shown) is connected to the sub RAM 202c as in the main RAM 200c, and even when the power is turned off, the data is retained without being erased. Like the main control board 200, the sub-control board 202 is also provided with a random number generator (random number generation means) 202d, and the random numbers generated by the random number generator 202d (hereinafter referred to as effect lottery random numbers) are mainly It is used to determine the mode of production.

In the sub control board 202, the sub CPU 202a functions by cooperating with the sub RAM 202c based on a program stored in the sub ROM 202b. It has a functional part.

The initialization determining unit 330 executes the initialization process in the sub control board 202. The command receiving unit 332 receives a command from another control board such as the main control board 200, and processes the command. The effect control means 334 receives the detection signal from the effect switch 122, and determines the effect of the game performed by each device of the liquid crystal display unit 124, the speaker 128, and the effect lamp 126 based on the received command. Specifically, the effect control unit 334 uses the image data displayed on the liquid crystal display unit 124 and the electric lights for effect through the illumination device such as the effect lamp 126, the sub credit display unit 134, and the sub payout display unit 136. The decoration data is determined, and at the same time, the audio data forming the audio to be output from the speaker 128 is determined. Then, the effect control unit 334 executes the effect of the determined game. Note that the production includes an auxiliary production. In the auxiliary production, when the selection winning type in which the correct answer and the incorrect answer are overlapped is won in the winning type lottery, the correct operation mode of the stop switches 120a, 120b, 120c, which is the winning condition of the correct winning combination, is notified. It is a production. By such an auxiliary effect, the player can easily display the symbol combination corresponding to the correct winning combination on the activated line A. An effect state in which such an auxiliary effect is executed is called an AT (assist time) effect state. In addition, a so-called ART game state in which an RT effect state and an RT (replay time) game state in which the winning probability of a replay combination is high may be used in parallel.

In the following, notifications managed by a substrate other than the main control substrate 200, including the sub control substrate 202, such as the liquid crystal display unit 124, the effect lamp 126, the speaker 128, the sub credit display unit 134, and the sub payout display unit 136. The means may be called other notification means. On the other hand, the notification means managed by the main control board 200, such as the main credit display section 130 and the main payout display section 132, may be referred to as a main notification means (instruction monitor). Further, the main notification means and other notification means capable of executing the auxiliary effect may be collectively referred to as an auxiliary effect notification means. The effect state control unit 314 causes the auxiliary effect informing unit to execute the auxiliary effect in the AT effect state.

(Table used in main control board 200)
FIG. 5 is an explanatory diagram for explaining a winning combination, and FIG. 6 is an explanatory diagram for explaining a winning type lottery table.

As will be described later in detail, the slot machine 100 is provided with a plurality of types of game states and effect states, and the game states and effect states are shifted according to the progress of the game. In the main control board 200, the main ROM 200b stores a plurality of winning type lottery tables and the like corresponding to the gaming states managed and controlled by the gaming state control means 312. The winning type lottery means 304 stores a corresponding winning type lottery table in the main ROM 200b in accordance with the current set value (indicating the ease of obtaining a game profit) stored in the main RAM 200c and the current game state. Based on the extracted winning type lottery table, it is determined which winning type in the winning type lottery table the winning type lottery random number acquired in response to the operation signal of the start switch 118 corresponds to.

Here, the winning combinations that make up the winning type extracted in the winning type lottery table include a replay combination, a small combination, and a bonus combination. When the symbol combination corresponding to the replay combination is displayed on the activated line A, the replay combination is a combination in which the player can execute the game again without making a new bet on the medal. The small winning combination is a winning combination in which a symbol combination corresponding to the small winning combination is displayed on the activated line A so that a predetermined number of medals can be paid out in accordance with the symbol combination. Further, the bonus combination, the symbol combination corresponding to the bonus combination is displayed on the activated line A, the gaming state managed by the gaming state control means 312 is a bonus gaming state (RBB operating gaming state described later). It is a role that can be transferred to.

As for the winning combination in the present embodiment, as shown in FIG. 5, a winning combination “replay” is provided as a replay combination. In addition, winning combinations "small winning 1" to "small winning 70" are provided as small winning combinations. Winning combinations “RBB” and “RB” are provided as bonus combinations. In FIG. 5, each of the left reel 110a, the middle reel 110b, and the right reel 110c is associated with one or more symbols constituting each winning combination.

Here, in the present embodiment, when the stop switch 120 is operated by the player, if the symbols forming the symbol combination corresponding to the winning combination that can be won are on the activated line A, the reel control means. By 306, stop control is performed so that the symbol stops on the activated line A. Further, when the stop switch 120 is operated, the symbols constituting the symbol combination corresponding to the winning combination that can be won are not on the activated line A, but the symbols in the direction opposite to the rotating direction of the reel 110 are 4 frames. When it exists within the range (drawing range) corresponding to the minutes, the number of symbols that are distant becomes the number of sliding symbols by the reel control means 306, and the symbols that form the symbol combination corresponding to the winning combination are valid. Stop control is performed so as to stop after the rotation for the number of slide frames is maintained so that the line A is pulled in. In addition, when there are a plurality of symbols corresponding to winning combinations that can be won in the reel 110, and all of them are within the drawing-in range of the reel 110, which symbol is determined on the activated line A according to a predetermined priority order. It is determined whether or not the drawing is to be drawn upward, and the stop control is performed so as to stop after maintaining the rotation for the number of sliding symbols so as to draw the prioritized symbol onto the effective line A. In addition, when the stop switch 120 is pressed, when the symbols constituting the symbol combination corresponding to the winning combination other than the winning combination that can be won are on the activated line A, the reel control means 306 causes the symbol. A so-called kick-off process for preventing the above from stopping on the effective line A is also executed in parallel. Further, as will be described later, when an operation mode (operation order or operation timing) is set as a winning condition in the winning combination included in the winning type, the reel control means 306 determines the winning combination in accordance with the operation mode of the player. Stop control is performed so that the symbol combination corresponding to can be displayed on the activated line A.

And, for example, the symbols constituting the symbol combination corresponding to the winning combination "replay", the winning combination "small combination 1" to "small combination 4" are always on the activated line A by the above stop control in each reel 110. It is arranged so that it can be displayed. Such a winning combination may be expressed as PB=1. On the other hand, for example, the symbols constituting the symbol combination corresponding to the winning combination “small winning combination 5” to “small winning combination 70”, the winning combination “RBB”, and the winning combination “RB” are obtained by the above stop control in each reel 110. Since they are not arranged so that they can be displayed on the effective line A, so-called spillage may occur. Such a winning combination may be expressed as PB≠1.

As shown in FIG. 6, in the winning type lottery table, a plurality of winning regions are sectioned, and the winning type targeted for the lottery differs depending on each game state, and whether or not there is a loss (unwinning). In FIG. 6, each gaming state (non-internal gaming state (non-internal), RBB inside medium gaming state (in RBB inside), RBB operating non-internal gaming state (RBB operating non-internal), RBB operating RB inside medium game The winning area (winning type) assigned to each state (RBB operating RB inside), RBB operating RB operating game state (RBB operating RB operating) is represented by "○", but actually The winning type lottery table corresponding to each of the plurality of gaming states is stored in the main ROM 200b. In the winning type lottery table, a predetermined number (winning range value) that is a numerical value indicating the winning range and a winning type are associated with each partitioned winning area, and all assigned for each gaming state. The total of the numbers of the winning areas is the total number of winning type lottery random numbers (65536). Therefore, the probability that each winning type is determined is a value obtained by dividing the number associated with the winning area by the total number of winning type lottery random numbers. Based on the gaming state at that time, the winning type lottery means 304 sequentially obtains the number from the one with the highest number among the plurality of winning regions in the relevant winning type lottery table, and the obtained number is the winning type lottery random number. When the value after subtraction becomes less than 0, the winning type associated with the winning area at that time is set as the lottery result of the winning type lottery. In addition, the numbers of all the winning areas of the winning area 1 or more are subtracted from the winning type lottery random number, and if the value after the subtraction is 0 or more, the winning type “miss” of the winning area 0 is the winning type lottery. It becomes the lottery result.

Here, the winning combination “RB” that constitutes the winning classification “RB” and the winning combination “RBB” that constitutes the winning classification “RBB” will be supplemented. The first-class special accessory RB is an accessory that increases the number of combinations of symbols related to winning for each specified number or increases the probability that the condition device related to winning for each specified number will operate. In this case, it means that it operates and can continue its operation until the result of the game is obtained not more than 12 times. Here, the condition device is a device whose operation is a condition necessary for displaying a combination of symbols relating to winning, re-playing, a character or an operation of the character continuously operating device, and a winning type lottery ( This means the one that operates when a lottery by an electronic computer performed in a gaming machine is won, that is, a winning flag. In addition, the accessory continuous operation device (winning combination “RBB”) related to the first-class special accessory that constitutes the winning classification “RBB” is a device that can continuously operate the first-class special accessory RB. Yes, it operates when a specific combination of symbols is displayed, and terminates the operation when predetermined.

According to the winning type lottery table of FIG. 6, for example, the winning area “0” is associated with the winning area 0, and when the winning type is won, the symbol corresponding to any winning combination shown in FIG. The combination is not displayed on the activated line A, and the medal is not paid out. However, as will be described later, when the RBB internal winning flag or the RB internal winning flag is carried over to the next game, the symbol corresponding to the winning "RBB" or the winning "RB" by winning the winning type "miss" The combination can be displayed on the activated line A. In addition, the winning region 1 is associated with the winning type “replay”, and when the winning type is won, the winning combination “replay” is always displayed on the activated line A (PB=1).

In addition, in the winning areas 2 to 37, the correct answer combination (the winning combination "small combination 1" to "small combination 4") that results in the payout number of 15 sheets and the incorrect combination combination (the winning combination "small combination" is small). The winning combinations (winning type “Bell order A1” to “Batting order bell D12”) that include duplicates of “role 5” to “small role 70”) are associated with each other. Then, when a plurality of small wins are won in a win type that is included in duplicate, a winning condition, such as a stop, for which a small combination corresponding to a small win is preferentially displayed on the activated line A. The order in which the switches 120a, 120b, 120c are operated is set.

In the following description, the operation of the stop switches 120a, 120b, 120c that stop the reels in the order of the left reel 110a, the middle reel 110b, and the right reel 110c is referred to as "bat order 1", and the left reel 110a, the right reel 110c, and the middle reel 110b are operated. The operation of the stop switches 120a, 120b, 120c for sequentially stopping the reels is referred to as "bat order 2", and the operation of the stop switches 120a, 120b, 120c for stopping the reels of the middle reel 110b, the left reel 110a, and the right reel 110c in order is called "bat order". 3", the operation of the stop switches 120a, 120b, 120c for stopping the reels in the order of the middle reel 110b, the right reel 110c, and the left reel 110a is "batt order 4", and the right reel 110c, the left reel 110a, the middle reel 110b are in this order. The operation of the stop switches 120a, 120b, 120c for stopping the reels is referred to as "Batting order 5", and the operation of the stop switches 120a, 120b, 120c for stopping the reels of the right reel 110c, the middle reel 110b, and the left reel 110a in the order of "Batting order 6". ".

For example, in the non-internal gaming state, when the winning type “bat order bell A1” in the winning area 2 is won and the operation is performed in the correct operation mode (bat order 1), the winning combination is 15 correct payouts. The stop control is performed so that the symbol combination corresponding to “small winning combination 1” is preferentially displayed on the activated line A. In addition, when the operation according to batting order 2 is performed, the symbol combination corresponding to the winning combination “small winning combination 53” which is an incorrect combination with one payout number is preferentially displayed on the activated line A with a probability of 1/2. If the stop control is performed as described above and the operation is performed in the batting order 3 or 4, the symbol corresponding to the winning combination "small winning combination 21" or the winning combination "small winning combination 31" that is an incorrect combination with one payout number When the stop control is performed so that the combination is preferentially displayed on the activated line A with a probability of 1/8, and when the operation by the batting order 5 or 6 is performed, the winning combination which is an illegal combination with one payout number The stop control is performed so that the symbol combination corresponding to the "winning combination 38" or the winning combination "small winning combination 48" is preferentially displayed on the activated line A with a probability of 1/8.

The winning probabilities (registered numbers) of the respective winning types within the groups of the winning regions 2 to 13, the winning regions 14 to 25, and the winning regions 26 to 37 are set to be equal. Since the player cannot usually know which winning type has been won, the player is made difficult to win the correct winning combination by providing the winning areas 2 to 37 as described above. Further, as described above, even if the stop switches 120a, 120b, and 120c are operated in the batting order in which the incorrect solution is preferentially displayed, the symbol combination corresponding to the incorrect solution is always displayed on the activated line A. However, depending on the operation mode, a dropout may occur (PB≠1).

In addition, the winning area 38 is associated with the winning type “small winning ALL” that includes the winning combinations “small winning 1” to “small winning 70” in duplicate, and the winning area 39 has a winning winning “small winning ALL”. The winning type “1 piece ALL” including the small winning combination 5” to “small winning combination 70” is associated with each other. Further, the winning area 40 is associated with the winning type “RBB” including the winning combination “RBB”, and the winning area 41 is associated with the winning type “RB” including the winning combination “RB”. Has been.

When one of the above-mentioned winning types is won, the internal winning flags corresponding to the respective winning types are established (turned on), and the stop control of each reel 110 is performed according to the establishment status of this internal winning flag. The Rukoto. At this time, although the winning combination including the small winning combination has been won, if the symbol combination corresponding to these winning combinations cannot be displayed on the activated line A in the game, after the end of the game. The internal winning flag is turned off. In other words, the winning right of a small winning role is limited to only within the game in which the winning type including the small winning role is won, and the right cannot be carried over to the next game. On the other hand, when the winning type including the winning combination "RBB" is won, the RBB internal winning flag is established (turned on), and the symbol combination corresponding to the winning combination "RBB" is on the activated line A. Until it is displayed, the RBB internal winning flag is carried over across games. Similarly, when the winning type including the winning combination "RB" is won, the RB internal winning flag is established (turned on), and the symbol combination corresponding to the winning combination "RB" is displayed on the activated line A. Until the RB internal winning flag is carried over across games. When the internal winning flag corresponding to the winning type that includes the winning role “Replay” that is the replay role is established, one of the winning roles “Replay” among the winning roles “Replay” included in the winning type The symbol combination corresponding to "" is always displayed on the activated line A, and after the processing necessary for performing the next game without requiring medals is performed, the internal winning flag is turned off.

(Transition of game state)
Here, the transition of the game state will be described with reference to FIG. Here, a plurality of gaming states such as a non-internal gaming state, an RBB internal gaming state, an RBB operating non-internal gaming state, an RBB operating RB internal gaming state, an RBB operating RB operating gaming state are prepared. As will be described later, each gaming state transits in accordance with winning of a bonus combination, winning (actuation), and completion.

The non-internal game state is a game state corresponding to the initial state in a plurality of game states. In such a non-internal game state, the winning probability of the replay combination is set to about 1/7.3. In the non-internal game state, the winning combination “RBB” is determined with high probability. Therefore, the number of stay games in the non-internal game state is shortened. The gaming state control means 312 shifts the gaming state to the RBB internal middle gaming state in accordance with the winning of the winning combination "RBB" (1).

In the RBB inside game state, the winning probability of the replay combination is set to about 1/7.3. Further, in the gaming state after the RBB inside gaming state, as will be described later in detail, with respect to some selection winning types, regardless of the operation order of the stop switches 120a, 120b, 120c of the player, the symbol corresponding to the correct answer The combination can be displayed on the activated line A. Therefore, in the RBB internal gaming state, non-internal gaming state in which the correct operation mode is required to display the symbol combination corresponding to the correct winning combination on the activated line A even for some selection winning types, and the winning of the replay winning combination Compared to other RBB operating non-internal game states where the probability is 0, RBB operating RB internal gaming states, RBB operating RB operating gaming states, the expected number of winnings per unit game is higher. Further, referring to FIG. 3A and FIG. 5, since the symbol combination corresponding to the winning combination “RBB” is PB≠1, the player intentionally does not arrange the symbol combination corresponding to the winning combination “RBB”. As a result, the gaming state inside the RBB can be extended. Here, in the RBB inside game state, by not performing the auxiliary effect (or not determining the AT effect state) even in the AT effect state, the player is in progress of the game state (to win the winning combination "RBB"). Display the corresponding symbol combination). Therefore, as a result, the number of stay games is shortened even in the RBB inside game state. When the symbol combination corresponding to the winning combination "RBB" is displayed on the activated line A, the gaming state control means 312 shifts the gaming state to the non-internal gaming state during RBB operation (2).

In the non-internal game state during RBB operation, the winning probability of the replay combination is set to zero. Therefore, as will be described later, the expected number of coins to be won per unit game can be made lower than that in the RBB inside game state. When the winning combination "RB" is won in the RBB operating non-internal game state, the game state control means 312 shifts the game state to the RBB operating medium RB inside game state (3).

In the RBB operating state, in the RB inside game state, the winning probability of the replay combination is set to zero. Therefore, as in the non-internal gaming state during RBB operation, the expected number of coins to be won per unit game can be set lower than that in the RBB internal gaming state. Further, referring to FIGS. 3A and 5, although the winning combination “RB” is PB≠1, the player can aim for a symbol combination corresponding to the winning combination “RB”. Here, as will be described later, by reducing the expected acquisition number per unit game in the RBB operating RB operating gaming state, to prevent the player from advancing the gaming state (a symbol corresponding to the winning combination "RB"). Prompt not to display the combination). In the RBB operating RB inside game state, when the symbol combination corresponding to the winning combination “RB” is displayed on the activated line A, the game state control means 312 changes the game state to the RBB operating RB operating game state. It will be transferred (4).

In RBB operation In RBB operation gaming state, the winning probability of the replay combination is set to zero. In the RBB operating gaming state, the winning type “small winning ALL” is set in the winning area 38 and the winning type “1 piece ALL” is set in the winning area 38 as a winning type. If you win the winning type "small winning ALL", the symbol combination corresponding to any of the winning roles "small winning 1" to "small winning 4" will be displayed on the activated line A, and you will win the winning type "1 piece ALL". Then, the stop control is executed so that the symbol combination corresponding to any of the winning combinations “small combination 5” to “small combination 70” is displayed on the activated line A. Here, due to the configuration of such a small winning combination, the expected number of sheets to be acquired per unit game in the RBB operating and RB operating gaming state is lowered. Hereinafter, the winning mode in the gaming state during the RBB operation will be described in detail.

Assuming that, in the winning type lottery table of FIG. 6, the number of the winning type “small winning all” in the winning region 38 in the RBB operating state and the RB operating state is 9156 and the winning type “1 piece ALL” in the winning region 39 is set. Let the number be 27469 (9156×3+1). In addition, in the other gaming states (non-internal gaming state, RBB internal medium gaming state, RBB operating non-internal gaming state, RBB operating RB internal medium gaming state), the winning type "bat order bell A1"- The number of "bats order bell C4" is 2099, the number of wins of each of the winning areas 14 to 25 is "bat order bell a1" to "bats order bell c4" is 190, and the winning type of win areas 26 to 37 is It is assumed that each of the "battal order bell D1" to "battal order bell D12" has a numerical value of 763. In addition, it is assumed that the number of winning types “replay” in the winning area 1 in the non-internal gaming state and the RBB internal middle gaming state is 8978. Here, in other gaming states, a plurality of types of correct winning combinations (here, the winning combination “small winning combination 1” to “small winning combination 4”) are won without overlapping each other, and in the RBB operating RB operating gaming state. Will be elected due to the duplication of multiple correct answers.

FIG. 8 is an explanatory diagram for explaining a winning mode in a gaming state during RBB operation. Referring to FIG. 8, in the RBB operation in the RB operation game state, in the winning type lottery, the probability that the winning type including the correct answer is won is 9156/65536, and the selection winning type including the incorrect answer is won. The probability of doing is 27469/65536. On the other hand, in the other game states (non-internal game state, RBB internal medium game state, RBB operating non-internal game state, RBB operating RB internal medium game state), the winning type including the correct winning combination The winning probability is 9156/65536 for each of the winning combinations “small winning combination 1” to “small winning combination 4”. It is assumed that the maximum probability of winning the selected winning type including an incorrect combination is 5341/65536 for each of the winning combinations “small winning combination 5” to “small winning combination” 70. Therefore, the operating probability of each condition device related to winning in the RBB operating game state during RBB operation is equal to or higher than that of the other game states, and at least the operating probability of the condition device related to incorrect solution is You can see it rising.

Also, the total number of winning areas related to winning in the RBB operating gaming state is 36625 (9156+27469), and the total number of winning areas related to winning in the other gaming state is 36624 (9156×4). ). Therefore, it can be understood that the total number of winning areas related to winning in the RBB operating gaming state in the RBB operating state is larger than in other gaming states. Here, by increasing the fraudulent combination with a small number of payouts by 1, the total number of winning regions related to winning is increased while suppressing an increase in the expected number of acquisitions per unit game.

In addition, when the winning type "small winning ALL" is determined in the RBB operating RB operating game state, the correct winning combination (here, the winning winning "small winning By displaying a symbol combination corresponding to "1" to "small winning combination 4") on the activated line A, the player can randomly operate the player to increase the lip-insertion payout rate, which will be described later, from the non-internal gaming state. be able to.

Here, in other gaming states, since multiple types of correct winning combinations are won without overlapping each other, it is possible to increase the chances of winning the correct winning combination (36624/65536), and as a result, for example, By performing the auxiliary effect in the AT effect state in another game state, it is possible to easily obtain the medal. On the other hand, in the RBB operating game state, because there are multiple types of correct winning combinations that are won in duplicate, there are few opportunities to win the correct winning combination (9156/65536), so AT effects in other playing states The chances of winning the correct winning combination are reduced compared to the state, and it is difficult to increase the number of medals owned by the player. Therefore, in terms of the medal acquisition performance, while the RBB is in operation, the RBB is in operation and the RB is in operation while the function of the RBB is in operation and the RB is in operation that the winning probability of a winning combination is higher than in other game states. It is possible to realize the specification that the game state is inferior.

Further, during the RBB operation, the expected number of acquisitions per unit game in the RBB operation is lower than the expected number of acquisitions per unit game in the bonus game state adopted in the conventional slot machine (for example, 2.52). Since it can be suppressed, the probability of winning medals throughout the game state will not increase too much and will not overwhelm the fire, and as a result of being kept low, the winning probability of small roles in other game states will be set higher. For example, in the AT effect state, the medal increase rate can be further improved.

Returning to FIG. 7, when the end condition of the winning combination “RB” is satisfied, that is, when the small combination wins a predetermined number of times (eg, 8 times) or the number of games reaches a predetermined number of times (eg, 12 times), the game state control is performed. The means 312 shifts the game state to the non-internal game state during RBB operation (5). Therefore, during the RBB operation, the game state control means 312 sequentially and repeatedly shifts the RBB operating non-internal game state, the RBB operating RB internal game state, and the RBB operating RB operating game state.

Any of the gaming states during RBB operation (non-internal gaming state during RBB operation, RBB operating during RBB internal gaming state, RBB operating during RB operating gaming state, hereinafter simply referred to as RBB operating gaming state (bonus gaming state)) When the ending condition of the winning combination "RBB" is satisfied during the stay in the crab (for example, when the number of obtained coins reaches a predetermined number), the game state control means 312 shifts the game state to the non-internal game state (6). ..

Therefore, the gaming state control means 312 sequentially shifts to a non-internal gaming state, an RBB inside gaming state, a gaming state after RBB operation (an RBB operating gaming state) as a large state transition, and a small state after RBB operation. As a transition, a non-internal gaming state during RBB operation, an RB internal gaming state during RBB operation, and an RB operating gaming state during RBB operation are repeatedly repeated in order. However, as described above, after the RBB operation, the RBB operation during the RB operation is not allowed to proceed to the gaming state, and the RBB inside gaming state promotes the progress to the non-internal gaming state during the RBB operation. Then, among the gaming states, the number of stay games in the three gaming states of the non-internal gaming state, the RBB operating non-internal gaming state, and the RBB operating RB internal medium gaming state becomes long.

Further, while transitioning the game state in this way, the AT effect state is determined in the non-internal game state, the RBB operating non-internal game state, the RBB operating RB internal medium game state. Then, the determined AT effect state is continued across the game state. Therefore, a plurality of game states may be sequentially transferred until the end condition of the AT effect state is satisfied. In particular, in the AT effect state, there is a high possibility that the end condition of the winning combination "RBB" will be satisfied, so the transition between the non-internal gaming state, the RBB operating non-internal gaming state and the RBB operating RB internal medium gaming state is performed. Repeats more often.

(Transition of performance state)
FIG. 9 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 by the effect state control means 314 on the main control board 200 will be described in detail.

(Non-AT production state)
As the non-AT effect state, a normal effect state and a chance effect state (chance zone) are provided. 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, so the number of medals that can be acquired is limited. The normal effect state is an effect state corresponding to the initial state among a plurality of effect states managed by the sub control board 202.

The production state control means 314 shifts the production state to the chance production state at a predetermined opportunity in the normal production state (1), and when the predetermined condition is satisfied in the chance production state, for example, a predetermined number of games are exhausted. Then, the normal production state is restored (2). Further, the effect state control means 314 can shift the effect state to the AT effect state in the normal effect state and the chance effect state (3). However, the chance production state is set so that it is easier to shift to the AT production state than the normal production state. For example, in both the normal effect state and the chance effect state, when the lottery (effect state lottery) determines 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 transitioning 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. Moreover, when a predetermined number of games are exhausted in the non-AT production state without shifting to the AT production state (so-called ceiling arrival), the production state control means 314 shifts the production state to the AT production state.

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

Further, in the AT effect state, three effect states such as a normal AT effect state, an interval effect state, and a chance AT effect state (specialized zone) 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 proceeds by managing the number of sets. Here, 50 games are exemplified as a set unit of the normal AT effect state, but the number of games can be set to another arbitrary number, the number of games can be changed by lottery, etc. It may be added. When the production state is set to the normal AT production state, the production state control means 314 subtracts 1 from the number of stocked (held) sets and sets the number of continuous games to 50 games. When the number of continuous games is over, the effect state control means 314 shifts the effect state to the interval effect state (4).

The interval effect state corresponds to a waiting period when the normal AT effect state continues after one set of the normal AT effect state is completed. Therefore, the production state control means 314 determines whether the remaining number of sets is 0 (whether the number of sets is stocked), and if the number of sets is not 0, after satisfying a predetermined end condition ( For example, after a predetermined number of games (for example, 50 games) has elapsed, the stocked number of sets is decremented by 1, and the effect state is shifted to the normal AT effect state (5). Here, 50 games are exemplified as a set unit of the interval effect state, but the number of games can be set to another arbitrary number, the number of games can be made variable by lottery, etc., and the number of games can be sequentially added by lottery, etc. It may be done. In addition, the number of predetermined games (for example, 100 games) is used to notify the transition to the normal AT effect state, and after the number of games has passed, the game performance is changed to the normal effect state. May be 50 games on average. Further, the effect state control means 314 can add the number of sets in the normal AT effect state by lottery during the interval effect state. Therefore, even if the remaining number of sets is 0, if the number of sets in the normal AT effect state is acquired during the interval effect state, the effect state control means 314 is stocked after satisfying a predetermined ending condition. The set number is subtracted by 1 to shift the effect state to the normal AT effect state (5).

The player can obtain the gaming profit by the auxiliary effect by alternately repeating the normal AT effect state and the interval effect state. Therefore, the player desires to obtain as many sets as possible and stay in the normal AT production state for a long time in order to progress the game favorably.

On the other hand, if the predetermined ending condition is satisfied, the effect state control means 314, for example, if the number of remaining sets is 0 and the number of sets in the normal AT effect state is not acquired during the interval effect state, AT The production state is ended, and the production state is shifted to the chance production state of the non-AT production state (6).

Further, the effect state control means 314 can shift the effect state to the chance AT effect state if the predetermined condition is satisfied in the normal AT effect state (7).

The chance AT effect state continues until a predetermined number of games have passed, during which the number of sets in the normal AT effect state is added. Then, when the predetermined number of games is over, the effect state control means 314 shifts the effect state to the normal AT effect state (8).

Note that in any of the effect states, when the winning condition or the dropout of a predetermined winning combination is used as the transition condition, a preparation state until the transition condition is satisfied (for example, from a non-AT effect state to a normal AT effect state (3 ), the interval effect state (6)) and the destination effect state may be changed.

Here, the reason for providing the interval effect state will be described in detail. If the normal AT effect state described above continues, the emissivity may increase excessively. For example, in the example of FIG. 6 to FIG. 9, when the auxiliary production is performed for all the selected winning types in the non-internal game state during RBB operation, the expected number of acquired sheets is about 8.38 (≈(15×9156× 4)/65536), and if the prescribed number is set to 3, the number of games will increase by 5.38 every game on average. Therefore, as described in (4) and (5) of FIG. 9, when the number of sets in the normal AT effect state continues, an interval is provided between them to adjust the expected acquisition number of sheets in the entire AT effect state.

Here, the interval has a high probability of executing the auxiliary effect, which shifts in a continuous advantageous section (a game section having performance related to the instruction function, that is, a game section in which the auxiliary effect (instruction function) is executed) ( Probability of executing the auxiliary production in a production state (for example, interval production state) in which the probability of executing the auxiliary production is lower than that in the production state in which the expected acquisition number is large (for example, normal AT production state) (small in the expected acquisition number) Is a production state for the purpose of reducing the overall expected acquisition number by continuing with a high production state. Therefore, the effect state control unit 314 continuously performs the AT effect by continuously performing the normal AT effect state in which the assist effect is performed and the interval effect state in which the frequency of the assist effect is lower than the normal AT effect state in the continuous advantageous section. We are adjusting the expected number of acquisitions for the entire state.

Specifically, the expected acquisition number of sheets in the entire AT production state can be adjusted by the expected acquisition number of games in the interval production state and the number of games. For example, by setting the probability of executing the auxiliary effect during the interval effect state to an arbitrary probability between 0% and 100%, the expected acquisition number of sheets in the interval effect state, and by extension, the expected acquisition number of sheets of the entire AT effect state is increased or decreased. can do. However, since the interval effect state is a part of the AT effect state, the probability of shifting (returning) to the normal AT effect state is higher than that in the normal effect state, or the number of sets in the normal AT effect state has already been set. It is desirable to set it so that it is more advantageous to the player than the normal production state or the chance production state, such as when a lot of stock lottery is performed. Further, not only the probability of executing the auxiliary effect, but also the number of games in the interval effect state can adjust the expected acquisition number of sheets in the entire AT effect state. For example, the longer the interval effect state is set, the more the expected acquisition number of sheets in the entire AT effect state can be reduced.

For example, as shown in FIG. 9, when the normal AT effect state and the interval effect state are alternately repeated, in the normal AT effect state, it is assumed that the expected acquisition number is 8.38 and 50 games continue. And, in the interval effect state, it is assumed that the expected acquisition number is 3.00 (no increase or decrease) and 50 games continue. Then, the expected number of coins obtained by combining both production states is about 5.66 (≈ (8.32×50+3.00×50)/100), and the increase of medals for each game is suppressed to 2.66. You can

Here, the interval effect state is described as the interval, but the present invention is not limited to this case and is executed after the normal AT effect state during the AT effect state or during the normal AT effect state, and the normal AT effect is performed. It suffices that the probability of executing the auxiliary effect is lower than that of the state, and for example, the normal effect state that can shift from the AT effect state and return to the AT effect state during the advantageous section can also be regarded as an interval.

In addition, in the AT effect state, one normal AT effect state has been described as an effect state in which the probability of executing the auxiliary effect is high (the expected acquisition number is large), but there are a plurality of such effect states. An interval may be provided between the performance states. At this time, the effect state control unit 314, in the continuous advantageous section, the first normal AT effect state and the second normal AT effect state for performing the assist effect, and the interval at which the assist effect frequency is lower than the AT effect state. By continuing the production state, the expected acquisition number of sheets in the entire AT production state is adjusted.

For example, in addition to the first normal AT effect state and the interval effect state that are the same as the above-described normal AT effect state, the second normal AT effect state is provided as an effect state with a high probability of executing the auxiliary effect, as in the first normal AT effect state. And Here, when the first normal AT effect state and the second normal AT effect state shift to each other effect state, the interval effect state is always passed. That is, the first normal AT effect state and the interval effect state, and the second normal AT effect state and the interval effect state can be changed to each other, but the first normal AT effect state and the second normal AT effect state are changed to each other. Does not move directly. At this time, in the first normal AT effect state and the second normal AT effect state, it is assumed that the expected acquisition number is 8.38 and the 50 games are continued. And, in the interval effect state, it is assumed that the expected acquisition number is 3.00 (no increase or decrease) and 50 games continue. Then, the expected number of coins obtained by combining both effect states is about 5.66 (?(8.38×50+3.00×50)/100), which is the same as in the above example, and the increase in the number of medals for each game is 2 It can be suppressed to 66 sheets. Here, an example has been described in which the expected number of acquired images in the first normal AT effect state and the second normal AT effect state are the same, but this is not the only case, and if the expected number of acquired characters is higher than in the interval effect state, Both may have different expected acquisition numbers.

(About game state)
By the way, the expected payout number per unit game may be divided by the specified number of bets, and the ratio may be called the payout rate. In addition, as the payout rate, in the game where the symbol combination corresponding to the replay combination is won, the payout rate including the rep, which is calculated as if the specified number of bets and the specified number of payouts have been made, and the game without that game And the bet and payout are calculated as 0, and there is a payout rate without lip. The lip-insertion ball output rate and the lip-outball ball output rate have the following relationship. In other words, if the payout rate is less than 100%, the payout rate with lip is higher than the payout rate with lip, and as the winning probability of the replay role is lower, the payout rate with lip and the payout rate without lip are higher. The difference with the rate becomes smaller.

Here, there is a case where a lower limit is set for the payout rate (particularly, the payout rate without rip) so that the player can continue the game for a long time while preventing the shooting performance from becoming excessively high. For example, the lip removal rate is set to a predetermined value (for example, 63%) or more. Here, the payout rate without lip is given as the payout rate that should be restricted, but in the actual game, the replay role wins, so intuitively the payout rate with lip becomes closer to the actual game. .. In order to have a wide range of games, such as increasing the expected number of coins to be acquired per unit game during the AT production state, it is preferable that the lip-insertion payout rate is small. However, since the lower limit is set for the rip-out payout rate, it is desirable to first lower the winning probability of the replay combination in order to make the rip-out payout rate as small as possible. This is because, as described above, the lip payout rate is higher than the lip drawout rate, but the lower the replay probability is, the smaller the difference between the lip included payout rate and the lip pulled out rate is. Is. Therefore, for example, the winning probability of the replay combination in the non-internal gaming state or the RBB internal middle gaming state is set to 1/7.3 which is the lower limit.

In addition, in the RBB operating gaming state (RBB operating non-internal gaming state, RBB operating RB internal gaming state, RBB operating RB operating gaming state), the winning probability of the replay combination can be set to 0. Then, the RIP in-progress ball rate in the RBB operating game state, which is the main stay game state of the AT effect state, becomes the lip-extracted ball rate, and it is possible to reduce the lip-introduced ball rate to the lip-extracted ball rate. .. Here, when the lip removal ball output rate is set to a predetermined value, in the non-internal gaming state or the RBB internal medium gaming state, the lip insertion ball output rate can be lowered only a little, but in the RBB operating gaming state, the lip insertion is performed. The payout rate can be lowered to the payout rate without lip. Therefore, even if all the gaming states are integrated, the lip-inserted payout rate can be reduced while maintaining the lower limit value of the lip-drawing-out payout rate, and the game performance can be improved.

When the payout rate is 100% or more, the payout rate without the lip is higher than the payout rate with the lip, and as the winning probability of the replay role is lower, the payout rate with the lip and the payout with the lip removed The difference with the rate becomes smaller. Then, even if the payout rate including the lip is the same, the lower the probability of winning the replay role is, the lower the dropout rate is. For example, the normal AT production state (including chance AT production state) of the expected acquisition number of 5 pieces per unit game (repeat payout rate 267%) is 300 games, and the expected acquisition number of 0 pieces per unit game (replacement output) If the winning probability of the replay role is 1/7.3 when 100 games are executed in the interval effect state of 100% of the ball rate), the winning rate of the replay role is 245%, whereas the winning probability of the replay role is If it is 0, the chance of winning out of the lip is 225%, and if the winning probability of the replay is 1/7.3, the rate of winning out of the lip is lower. It can be understood that the payout rate is also advantageous.

Furthermore, when designing the lip removal ball rate in the AT production state, if the replay role is won during the AT production state, even if the replay role wins (wins), the replay role wins Since it is not converted into a rate (betting and payout are calculated as 0 for the game), the design becomes complicated and the work load increases. However, here, since the replay role itself is not elected in the RBB operating game state where it is assumed that the AT effect state is to stay for a long time, the normal AT effect state, the interval effect state, and the chance AT effect state are individually output. It is easy to design the ball rate and the ball output rate in the entire AT effect state via the interval effect state, and the work load can be reduced.

The state transition of the game state shown in FIG. 7 has the following problems. For example, referring to FIG. 3A and FIG. 5, since the symbol combination corresponding to the winning combination “RBB” is not PB≠1, the player intentionally sets the symbol combination corresponding to the winning combination “RBB”. By not aligning, it is possible to extend the game state. Here, as described above, in the RBB inside middle game state, by not performing the auxiliary effect, the player is prompted to proceed with the progress of the game state (display of the symbol combination corresponding to the winning combination "RBB"). . In addition, the symbol combination corresponding to the winning combination "RBB" is set to be the same as the symbol combination corresponding to the so-called rare combination, for example, the stop range is the same as the symbol range of the first stop, and the result is the result. Alternatively, the player may always aim for a symbol combination corresponding to the winning combination “RBB”.

Further, referring to FIG. 3A and FIG. 5, although the winning combination “RB” is PB≠1, the player has a symbol corresponding to the winning combination “RB” in the RBB operating RB inside game state. You can aim for combinations. Here, as described above, by lowering the expected number of acquisitions per unit game in the RBB operating RB operating gaming state, the player is prevented from progressing to the gaming state (the symbol corresponding to the winning combination "RB"). Respond by prompting (not to display the combination). In this way, by making it disadvantageous for the player to stay in the game state or shift the game state, it is against the player that the player intends to stay in the game state or shift the game state against the game property. , There is no need to set a penalty.

Further, as another problem, when the production state becomes the AT production state, even if the game state is the RBB operating game state, the ending condition is immediately satisfied (when the predetermined number is reached. Therefore, the game state shifts to the non-internal game state. Therefore, when the production state shifts to the AT production state, the stay ratio in the non-internal game state or the RBB internal medium game state increases. For example, in the non-AT production state, the stay ratio in the non-internal game state and the RBB inside middle game state is 2%, whereas in the AT production state, it is 10%. Further, the higher the set value, the higher the payout rate (the longer the period of staying in the AT effect state), and the higher the stay ratio in the non-internal gaming state or the RBB inside middle gaming state. In such a non-internal game state and an RBB internal medium game state, the replay combination is won with a probability of 1/7.3. Therefore, the higher the setting, the higher the stay ratio in the non-internal gaming state or the RBB internal middle gaming state, and accordingly, the winning probability of the replay combination becomes higher. The player can estimate the set value by such a difference in the winning probability of the replay combination.

By the way, as described above, if the winning probability of the replay combination is different between the game states, even if one of the lip-insertion payout rate and the lip-drawout payout rate is made equal, the other is different. For example, if the non-internal gaming state in which the winning probability of the replay role is 1/7.3 and the RBB active gaming state in which the winning probability of the replay role is 0 are set to the lower limit, the non-internal game The rip-in ball-out rate in the state is higher than the rip-in ball-out rate in the RBB operating game state. Then, in the game property in which the winning of the winning combination "RBB" is not recognized, the expected number of coins to be won per unit game is increased only in some gaming states, which gives the player a feeling of strangeness. In addition, if the expected number of coins to be acquired per unit game becomes high only in a part of the game state, there is a possibility that the game state may be intentionally extended or the game may be conquered. Therefore, it is considered to make the payout rate including the rips approximately equal so that the difference in the payout rate in the actual game is not felt.

Here, in response to the winning of the winning combination “RBB”, the stop control is changed. Therefore, as described above, from winning the winning combination "RBB" until the end condition is satisfied, in particular, RBB internal medium gaming state, RBB operating non-internal game state and RBB operating RB internal medium gaming state. In the meantime, with respect to some of the selected winning types, the symbol combination corresponding to the correct winning combination is displayed on the activated line A regardless of the operation mode (operation order) of the player. In this way, the expected winning number per unit game is increased to increase the lip payout rate during the RBB internal medium gaming state, the RBB operating non-internal gaming state, and the RBB operating RB internal medium gaming state to the non-internal gaming state. Match the payout rate with rep.

For example, taking the winning type “bat order bell A1” in the winning area 2 as an example, when the player operates in the batting order 1 which is the correct operation mode, the winning combination “small win 1” with 15 payout numbers is 100% ( You can win with PB = 1), and if you operate in batting order 2, you can win the winning combination "small winning combination 53" with a probability of 1/2 with a probability of 1/2, and if you operate with batting order 3 or 4, you will get 1 payout Winner "Small Win 21" or Winner "Small Win 31" can be won with a probability of 1/8, and if you operate in batting order 5 or 6, you can win "Winner 38" or Win You can win "Small Win 48" with a probability of 1/8. Therefore, when the player randomly operates the stop switches 120a, 120b, 120c at the time of winning the selected winning type in the winning areas 2 to 25, the expected number of winnings per unit game is (15+0.5+0.125×4). /6=2.7. Then, if the stop control of the winning type “Batting order Bell A1” is changed so that the winning role “small role 1” is made to win 100% regardless of the operation mode of the player, the expected number of acquisitions per unit game Will be 15. In this way, by changing the stop control for some of the selected winning types, it is possible to increase the expected number of coins to be acquired per unit game, that is, to increase the rip-in payout rate.

However, after the winning of the winning combination “RBB”, the winning probability of the replay winning combination in the RBB active gaming state is 0, but the winning probability of the replay winning combination cannot be 0 in the RBB internal gaming state. Therefore, by changing the stop control, if the RBB in-game state during play is adjusted to match the non-internal game state, the RBB in-game state during play is increased. As for the gaming state during the inside of the RBB, as described above, by not determining the AT effect state, the player is urged to proceed to the gaming state.

Here, returning to FIG. 6, the winning type lottery table will be described in detail. Here, the batting order 1 and the batting order 2, the batting order 3 and the batting order 4, and the batting order 5 and the batting order 6 with the same first stop in the correct operation mode are simply referred to as batting order pairs. In the AT production state, while increasing the expected number of acquisitions per unit game when the player operates in the correct operation mode, the expected acquisition per unit game when the player does not operate in the correct operation mode There is a desire to reduce the number of sheets as much as possible. However, in the selection winning type of the winning areas 2 to 25, when the batting order is a batting order pair of the batting order which is the correct answer operation mode, the expected number of coins to be won per unit game cannot be lowered so much, and the incorrect batting is performed. There is a one-half chance of winning the prize. This is for the following reason.

FIG. 10 is an explanatory diagram for explaining the stop control of the selected winning type. For example, it is assumed that when the player wins the win type "Batting Order Bell A1", the player operates the batting order 2 which is a batting order pair of the batting order 1 which is the correct operation mode, as follows. As shown in FIG. 10A, the winning type “Batting Order Bell A1” includes a winning role “small role 1”, a winning role “small role 21”, a winning role “small role 31”, and a winning role “small role 38”. , A winning combination “small combination 48”, and a winning combination “small combination 53” are duplicated. Therefore, at this point, the winning prizes that can be won are the winning prize "small prize 1", the winning prize "small prize 21", the winning prize "small prize 31", the winning prize "small prize 38", and the winning prize "small prize". 48”, and the winning role “small role 53”.

Then, when the player operates the stop switch 120a corresponding to the left reel 110a as the first stop, the reel control means 306 causes the winning combination "small win 1" in which the payout number is maximum, as shown in FIG. ”, and tries to stop on the effective line A. Since the winning combination "small combination 1" is PB=1, the symbol "bell B" on the left reel 110a of the symbol combination corresponding to the winning combination "small combination 1" always stops on the activated line A. However, at this point in time, since it is unclear which of the stop switch 120b and the stop switch 120c is to be operated by the player next, there is a possibility that both the batting order 1 and the batting order 2 are operated. That is, even if the player tries to make a batting order 2, the batting order 1 (correct winning combination) is still possible when the left reel 110a is stopped, and therefore the correct winning combination cannot be denied. Therefore, at this point, the winning combination that can be won is limited to the winning combination "small combination 1" and the winning combination "small combination 53".

Then, when the player operates the stop switch 120c corresponding to the right reel 110c as the second stop, the reel control means 306 maximizes the number of symbol combinations of winning combinations as shown in FIG. Then, the winning combination “small combination 53” is given priority and stopped on the activated line A. However, if the symbol of the right reel 110c is PB≠1 in the symbol combination corresponding to the winning combination “small winning combination 53”, the symbol corresponding to the winning combination “small winning combination 1” with PB=1 by stop control. There is a possibility that the combination will stop. Therefore, the symbol of the right reel 110c in the symbol combination corresponding to the winning combination "small winning 53" is different from the symbol of the right reel 110c in the symbol combination corresponding to the winning combination "small winning 1", and PB=1. Must. Here, the symbol "bell B" is associated. Therefore, when the player operates the stop switch 120c according to the batting order 2, the symbol "bell B" always stops on the activated line A. Thus, at this time point, the improper combination of one payout number is stopped at PB=1. Therefore, at this point, only the winning combination “small winning combination 53” can be won.

Then, when the player operates the stop switch 120b corresponding to the middle reel 110b as the third stop, the reel control means 306 causes the winning combination “small winning combination 53” with a possibility of winning as shown in FIG. 10(d). To stop on the effective line A. However, among the symbol combinations corresponding to the winning combination “small winning combination 53”, the symbols on the middle reel 110b are the symbol “blue star” and the symbol “blue 7”. Therefore, referring to FIG. 3A, when the player does not operate when the symbol numbers 3 to 12 of the middle reel 110b are located on the activated line A, the winning combination "small winning 53" Can't stop. Then, when the player randomly performs the operation in the batting order 2, the winning combination "small combination 53" which is an incorrect combination can be won only with a probability of 1/2.

Here, when the player performs the second stop, the reel control means 306 corresponds to the right reel 110c of the winning combination "small winning combination 53" on the condition that the number of symbol combinations of the winning combination is the maximum. The pattern to be stopped is stopped on the effective line A. In other words, the number of symbols corresponding to the middle reel 110b of the winning combination "small combination 53" must be larger than that of the winning combination "small combination 1". For example, here, the winning combination "small winning part 1" is one "Bell A" symbol, whereas the winning combination "small winning part 53" is two symbols "blue star" and "blue 7". is there.

In this way, when the batting order is a batting order pair of batting orders in the correct operation mode, the incorrect solution is won with a probability of 1/2. However, at the time of execution of the second stop, if the improper winning combination is determined to be the winning combination “small winning combination 53” from the stop mode, the player makes a symbol number 3 to 12 in the third stopping. By performing the stop operation when any one is located on the activated line A, it is possible to win the improper combination with a probability of 100% instead of 1/2. Then, the payout rate changes depending on the knowledge and skill of the player. Therefore, by providing a plurality of fraudulent winning combinations that are exclusively won by the player's operation and arranging them in the winning areas as different winning types, the unit game when the player does not operate in the correct operation mode Equalize the expected number of acquisitions. Here, the exclusive means that the symbol ranges that can be stopped on the effective line A by the stop control on the reel 110 (the range of consecutive symbols) do not overlap, and if all the symbol ranges are combined, the reel 110 It means that it becomes all patterns.

Here, the symbol stopped by the first stop is a correct combination, and a plurality of winning combinations in which an incorrect combination is confirmed by the second stop are provided. For example, in the winning type “bat order bell A2”, when operated in the batting order 2 which is the batting order pair of the batting order 1 which is the correct operation mode, the winning combination “small win 54” can be won with a probability of 1/2. Here, as for the winning combination “small combination 53” and the winning combination “small combination 54”, as can be understood with reference to FIG. 3A, the arrangement of the symbols corresponding to the middle reel 110b is exclusive. There is. That is, in the winning combination "small winning combination 53", the winning combination "small winning combination 53" can be won by operating when any of the symbol numbers 3 to 12 of the middle reel 110b is located on the activated line A, In the winning combination "small winning combination 54", if any of the symbol numbers 0 to 2 and 13 to 19 of the middle reel 110b is positioned on the activated line A, the winning combination "small winning combination 54" is won. it can.

The winning type “batting order bell A1” including the winning combination “small winning combination 53” and the winning type “batting order bell A2” including the winning combination “small winning combination 54” have the same winning probability, and the player stops for the second time. It is not possible to determine which winning type has won at the time of finishing. Therefore, the player has no choice but to aim at any winning combination by relying on intuition or to randomly operate it, and it is possible to reduce the winning probability of illegal combination to 1/2. In addition, the winning combination "small combination 53" and the winning combination "small combination 54" become all the symbols of the middle reel 110b when the symbol ranges of the medium reel 110b that can be stopped by the stop control are combined. In this way, by not providing a stop position that results in an un-winning, it is possible to prevent the payout rate from changing depending on the knowledge and skill of the player.

Here, an incorrect answer is obtained when one winning combination (eg, winning combination “small winning combination 1”) that can be won by one correct operation mode is operated in a batting order that is a batting order pair of batting order in the correct operating mode. At least two winning combinations must be provided (for example, the winning combination "small winning combination 53" and the winning combination "small winning combination 54"), and the winning classification pair (correct winning combination pair) that includes them must be (for example, the winning classification " The batting order bell A1" and the winning type "batting order bell A2") are required. Therefore, when batting orders 1 to 6 are equally distributed as correct answer operation modes, a correct answer hand pair must be provided for each correct operation operation mode. Therefore, if batting orders 1 to 6 are provided as correct operation modes, a total of 12 winning types are required.

In addition, within the constraint of the number of symbols (for example, 10 or less), the symbol range at the time of the third stop of the incorrect solution when the player operates in a batting order that is a batting order pair of the correct operating mode is different. If it can be divided into three or more, it is possible to reduce the odds of winning an incorrect combination to 1/3 or less.

By the way, as described above, here, during the RBB internal gaming state, RBB operating non-internal gaming state and RBB operating RB internal medium gaming state, the correct answer is given regardless of the operation mode of the player regarding the selection winning type. The symbol combination corresponding to the combination is displayed on the activated line A, the expected number of coins per unit game is increased, and the RBB internal medium gaming state, the RBB operating non-internal gaming state and the RBB operating medium RB internal medium gaming state ( It is designed to match the rip-in payout rate during the bonus game state) with the rip-in payout rate in the non-internal game state (a predetermined game state different from the bonus game state). However, regardless of which one of the selection winning types is won, if the symbol combination corresponding to the correct winning combination is always displayed on the activated line A, the expected number of coins to be won per unit game becomes too high. Therefore, the winning area to be won for the selected winning type is duplicated, two winning areas of the same nature are provided, and duplicated during the RBB internal gaming state, the RBB operating non-internal gaming state and the RBB operating RB internal gaming state. Only in one of the winning areas, the symbol combination corresponding to the correct winning combination can be displayed on the activated line A without fail.

FIG. 11 is an explanatory diagram for explaining copying of the winning area. For example, consider allocating the selection win type in the win type lottery table. As described above, the selection winning type is the correct operation mode, that is, the batting order 1 in order to reduce the winning probability of incorrect batting when operating in the batting order of the batting order of the correct operating mode to 1/2. Correct answer pairs are formed for each of ~6. Referring to FIG. 11, among the winning types “Batting order bell A1” to “Batting order bell C4” in the winning areas 2 to 13, the winning type “Batting order bell A1”, the winning type “Batting order bell A3”, and the winning type “Batting order bell B1” , Win type "bat order bell B3", win type "bat order bell C1", win type "bat order bell C3", win type "bat order bell A2", win type "bat order bell A4", win type "bat order bell B2" ], the winning classification “batting order bell B4”, the winning classification “batting order bell C2”, and the winning classification “batting order bell C4”, respectively, form the correct answer pair.

Here, the groups (winning areas 2 to 13) in which the correct answer pairs are formed are further duplicated for the batting orders 1 to 6 which are the correct operation modes. That is, the selected winning type having the same property as the selected winning type consisting of the groups of the winning regions 2 to 13 is duplicated in the winning regions 14 to 25. Also in the selection winning type of the winning areas 14 to 25, since the winning probability of incorrect answer is ½ when the batting order is a batting order pair of the batting order which is the correct operating mode, the batting order 1 is the correct operating mode. Correct answer pairs are formed for each of ~6.

Then, using the winning area thus increased, in the non-internal gaming state, the correct winning combination is won only when the operation in the correct operating mode is performed in all the selected winning types of the winning areas 2 to 25, In the RBB internal gaming state, the RBB operating non-internal gaming state, and the RBB operating in the RB internal gaming state, the correct answer combination is performed only when the operation in the correct operation mode is performed in the selected winning type of the winning areas 2 to 13. In the selected winning type in the winning areas 14 to 25, the stop control is changed and 100% of the winning combination “small winning combination 1” to “small winning combination 3” is achieved regardless of the operation mode of the player. Make a prize. In this way, when the selected winning type in the winning areas 14 to 25 is won, in the non-internal gaming state, the expected number of winnings per unit game is 2.7, but the RBB inside medium gaming state, RBB operation In the non-internal game state and the RBB operation in the RB internal medium game state, it becomes 15 sheets. Therefore, it is possible to set a high expected acquisition number per unit game in the RBB internal gaming state, the RBB operating non-internal gaming state, and the RBB operating RBB internal gaming state. The difference in the expected number of coins per unit game can be derived by multiplying the probability that any of the winning regions 14 to 25 is determined by 12.3 (15-2.7). Therefore, by adjusting the probability that any of the winning regions 14 to 25 is determined, it can be understood that the expected number of coins to be won per unit game in each gaming state can also be adjusted.

Here, for example, it is considered to adjust the average of the rip-out removal rate in all game states to 63%. In the non-internal gaming state in which the winning probability of the replay combination is 0 and in the RBB operating state in which the RBB is operating and the RBB is in the in-game state, the winning probability of the replay combination is 1/7.3 because the winning rate of the replay winning is equal to the winning rate of the replay winning. By staying in the non-internal game state, there is a difference between the lip-insertion payout rate and the lip-drawout payout rate. If the stay ratio between the non-internal gaming state, the RBB internal gaming state, the RBB operating non-internal gaming state, and the RBB operating RB internal medium gaming state is 2:8, the rip-in ball-out rate in the non-internal gaming state is The difference in the ball extraction rate without lip will affect with a probability of 20%. For example, in the non-internal game state, if the difference between the lip-insertion payout rate and the lip-drawout payout rate in the vicinity of 63% is 10%, then The difference is 2 (10×2/10)%. Therefore, if the non-internal gaming state, the RBB internal medium gaming state, the RBB operating non-internal gaming state, and the RBB operating medium RB internal medium gaming state are unified to 65%, it is possible to extract the lip in the non-internal gaming state. The ball rate is 57%, the RBB internal gaming state, the RBB operating non-internal gaming state, and the RBB operating RB internal medium gaming state, the lip removal ball rate is 65%. Here, although the non-internal gaming state, the RBB internal medium gaming state, RBB operating non-internal gaming state and RBB operating RB internal medium gaming state, the rip removal rate is different, but the average rip removal rate Can be set to 63% or more, which is equal to or higher than the lower limit, and it is possible to reduce the lip-insertion payout rate while making the lip-insertion payout rate equal.

Here, the stay ratio between the non-internal gaming state, the RBB internal gaming state, the RBB operating non-internal gaming state and the RBB operating RB internal gaming state is set to 2:8, but in the non-internal gaming state The lower the stay ratio of, the less the influence of the difference between the lip-insertion payout rate and the lip-drawout payout rate in the non-internal gaming state on the difference between the total lip-insertion payout rate and the lip-drawout payout rate. . For example, by making the stay ratio in the non-internal game state as close to 0 as possible, the difference between the total rip-in payout rate and the total rip-out payout rate also approaches 0. By doing so, it is possible to bring the lip inclusion ball output rate close to 63%, which is the lower limit of the lip extraction ball output rate.

In this way, the expected winning number per unit game can be adjusted by duplicating the selected winning type. However, even if the nature of the winning type is duplicated, the duplicate winning combination cannot be duplicated as it is. Overlapping winning combinations must be different between different winning types. Therefore, in order to control the stop, a new winning combination must be provided separately, and the newly created winning combination must be duplicated in the duplicated winning classification, and the winning combinations overlapping in the winning classification must be apparently different. . However, if the number of new small roles is increased unnecessarily for duplication of the winning area, labor is required to verify the validity. Therefore, in the present embodiment, by duplicating the overlapping mode of the winning combinations, the winning area is duplicated without increasing the number of unnecessary winning combinations for the stop control.

FIG. 12 is an explanatory diagram for explaining overlapping winning combinations among the winning types. Here, the winning combinations that make up the winning classification "Batting Bell A1" (first selection winning classification) are the winning combination "small winning combination 1" (specific correct winning combination), the winning combination "small winning combination 21", and the winning combination "small winning combination". 31", winning role "small role 38", winning role "small role 48" (winning role "small role 21", winning role "small role 31", winning role "small role 38", winning role "small role 48" Any or all of them are the first incorrect answer), and the winning combination “small combination 53” (the second incorrect combination different from the first incorrect combination) is the correct combination pair, and the winning type “is”. The winning combination that constitutes the batting order bell A2" (second selection winning type) is the winning combination "small combination 1" (specific correct combination), the winning combination "small combination 23", the winning combination "small combination 29", and the winning combination " Small role 40", winning role "small role 46" (winning role "small role 23", winning role "small role 29", winning role "small role 40", winning role "small role 46", or All are different from the first incorrect solver and the second incorrect solver, the third incorrect solver), and the winning combination “small win 54” (the first incorrect solver, the second incorrect solver, and the third incorrect solver). 4th wrong answer). Then, the winning combination that constitutes the winning type “Batting order bell a1” (third selection winning type) that duplicates the winning area is the winning combination “small winning combination 1” (specific correct winning combination), the winning combination “small winning combination 21”, Winning role "Small role 31", winning role "Small role 38", winning role "Small role 48" (Winning role "Small role 21", winning role "Small role 31", winning role "Small role 38", winning role Any or all of the "small wins 48" are the first incorrect answer) and the winning wins are "small wins 54" (the fourth incorrect unlock), and the winning type "Battle Bell" is the correct answer pair. a2” (the fourth selection winning type), the winning combination is “winning part 1” (specific correct answer), winning part “small part 23”, winning part “small part 29”, winning part “small part” 40", winning role "small role 46" (winning role "small role 23", winning role "small role 29", winning role "small role 40", winning role "small role 46", or all The third incorrect fraudulent combination), and the winning combination “small winning combination 53” (the second incorrect fraudulent combination).

Here, with respect to the batting orders 1 to 6 which are the correct operation modes, the winning type between the winning type “batting order bell A1” and the winning type “batting order bell A2” in the group in which the correct answer hand pair is formed, respectively. Only the constituent winning part "small part 53" (second incorrect answer) and the winning part "small part 54" (fourth incorrect part) are exchanged, and other winning parts are maintained as they are, In this group, the winning type is “bat order bell a1” and the winning type is “bat order bell a2”. As can be understood with reference to FIG. 5, the winning combination “small winning combination 53” and the winning combination “small winning combination 54” are both operated in batting order 2 which is a batting order pair of batting order in the correct operation mode. The symbol range displayed on the activated line A on the middle reel 110b corresponding to the third stop is mutually exclusive.

Similarly, as for other correct answer pairs of the selected winning type, as shown in FIG. 12, it is only necessary to exchange the incorrect answers in which the symbols of the reel 110 corresponding to the third stop are mutually exclusive. It is possible to make different winning combinations that are different between different winning types.

In this way, the winning area is duplicated in order to adjust the expected number of coins to be won per unit game by exchanging incorrect answers when operating in a batting order that forms a batting order pair in the correct operation mode. As a premise, in the duplicated winning area, it is possible to realize duplication of the winning area without increasing unnecessary winning combinations for stop control.

In addition, regarding the correct combination, here, when the batting order of the batting order of the correct operating mode is operated, the symbol range of the reel 110 corresponding to the third stop is mutually exclusive. Although the example of exchanging each other has been described, the present invention is not limited to such a case, and it is sufficient to exchange an illegal combination having different symbol ranges of the reel 110 corresponding to the third stop.

In addition, when the batting order of the batting order of the correct answer operation mode is operated, the correct answer operation mode is not limited to the case of exchanging incorrect answers with different symbol ranges of the reel 110 corresponding to the third stop. When operating with a batting order pair different from the batting order pair of batting orders, it may be possible to exchange illegal combinations with different symbol ranges of the reel 110 corresponding to the second stop or the third stop. For example, only the winning combination “small winning combination 53” and the winning combination “small winning combination 54” that constitute the winning classification between the winning classification “batting order bell A1” and the winning classification “battal order bell A2” in FIG. An example of exchanging is given, but one of the winning combination “small part 21” and the winning part “small part 31” constituting the winning type, and the winning combination “small part 23” and the winning part “small part”. Any one of the small winning 29" and the unacknowledged combination of the winning combination "small winning 38" and the winning "small winning 48" and the winning "small winning 40". It is possible to realize the duplication of the winning area without increasing the unnecessary winning combination for stop control by exchanging any one of the winning combinations “small winning combination 46” with the incorrect combination. .

In addition, here, the winning combination "small win 53" and the winning combination "small win 54" that compose the winning classification are exchanged between the winning classification "battle bell A1" and the winning classification "battal bell A2". By doing so, an example in which the winning area is duplicated once has been described, but three or more duplications can be performed by exchanging a plurality of such winning combinations. For example, between the winning type “Batting Order Bell A1” and the winning type “Batting Order Bell A2”, the winning combination “small part 53” and the winning combination “small part 54” constituting the winning type are exchanged, One of the winning combinations "small part 21" and the winning part "small part 31" is wrongly resolved, and one of the winning part "small part 23" and the winning part "small part 29" is incorrect. By exchanging, that is, by making the number of exchanges twice, it is possible to make the total number of groups of originals and duplicates 2 to the number of exchanges, that is, four.

By the way, as described above, in the RBB operating RB operating gaming state, the winning type "small winning ALL" and the winning type "1 sheet ALL" are set as the winning types that can be won. Also, in order to lower the expected number of coins per unit game in the RBB operating RB operating gaming state, the winning type in the RBB internal gaming state, the RBB operating non-internal gaming state and the RBB operating RB internal medium gaming state It is preferable that the number of types of selection wins, each of which includes a correct winning combination that constitutes the “small winning combination ALL”, be the same, and that the numbers of the winning combinations are equal (here, unified to 9156) or very close. The following four reasons are adopted as the correct winning combination "winning combination 1" to "small winning combination 4".

FIG. 13 is a diagram in which a part of the winning type lottery table of FIG. 6 is extracted. First, as in the winning areas 2 to 13 in FIG. 13, one correct answer is associated with each batting order pair (batting order 1 and batting order 2, batting order 3 and batting order 4, batting order 5 and batting order 6). Here, as the correct winning combination, for example, the winning combinations “small winning combination 1” to “small winning combination 3” are mentioned. In this way, the expected number of coins per unit game can be evenly distributed to the operation mode (bat order), while the expected number of coins per unit game can be set low when there is no auxiliary effect, and the RBB is in operation. It is possible to set a low expected number of coins to be acquired per unit game in the gaming state during RB operation.

Further, in order to further reduce the expected number of coins to be won per unit game, or to increase the variation of correct answers to make it difficult for the player to grasp the determined winning type at the first stop, such an expectation per unit game It is conceivable to increase the number of groups of the selected winning type with the same number of acquisitions. For example, it is possible to provide three more winning combinations as correct answers, and to correspond to each of the batting order pairs like the winning combinations “small combination 1” to “small combination 3”. However, if the correct winning combination is further increased by three from the winning combinations “small winning combination 1” to “small winning combination 3”, the number of symbol combinations becomes too large and the stop control becomes complicated. Also, if you try to increase the number of correct answers by only two, there will be three batting order pairs, but there will be two correct answers, and if the numbers of correct answers are equal, two correct answers will correspond to one batting order pair. The stop control becomes more complicated. If one batting order pair corresponds to one correct answer combination and two batting order pairs correspond to one correct answer combination, the expected number of coins per unit game becomes uneven with respect to the operation mode (batting order), or RBB. During operation RB During operation, the expected number of acquisitions per unit game in the game state cannot be lowered sufficiently. Therefore, here, the correct winning combination is increased by one from the winning combinations “small winning combination 1” to “small winning combination 3”, and a combination of selected winning types in which the expected number of coins per unit game is even is provided. Here, the winning combination “small winning combination 4” is given as the correct answer, and the winning type is set as in the winning areas 26 to 37 in FIG.

In the winning areas 26 to 37, the winning combination “small winning combination 4” which is a correct answer and the winning classifications “bat order bell D1” to “bat order bell D12” which are included in duplicate are associated with each other. There is. Here, unlike the selection winning type in the winning regions 2 to 13, when the player operates in a batting order other than the correct operation mode, the correct winning combination “one piece winning combination” is set with a probability of 1/2. Therefore, when the player randomly operates the stop switches 120a, 120b, and 120c, the expected number of coins per unit game is 2.7, while the number of selected prizes in the prize areas 2 to 13 is 2.7. The selection win type of the regions 26 to 37 is as large as (15+0.5×5)/6=2.9. For example, here, considering that the number of correct answers is equal to 9156 in order to reduce the expected number of coins to be won per unit game in the RBB operating game state, the winning combination “in the RBB operating game state” is considered. Winning type including small win 1 = Winning win including winning win "small win 2" = Winning wins including winning win "small win 3" = Winning wins including winning win "small win 4" Win area 2 Since the ratio of the 13 selection win types to the selection win types of the win areas 26 to 37 is 3:1, the overall expected number of coins to be won per unit game is (2.7×3+2.9)/4. = 2.75 sheets. Therefore, although the expected number of coins per unit game increases to some extent, the expected number of coins per unit game can be further lowered.

In the winning areas 26 to 37, as in the winning areas 2 to 13, groups in which correct answer pairs are formed are required for the batting orders 1 to 6 which are the correct operation modes. For example, in the example of FIG. 13, in addition to the correct answer pairs of the winning regions 2 to 13 described above, the winning type “batting order bell D1” among the winning types “batting order bell D1” to “batting order bell D12” of the winning regions 26 to 37. "Winning order bell D3", winning classification "Batting order bell D5", winning classification "Batting order bell D7", winning classification "Batting order bell D9", winning classification "Batting order bell D11" , The winning type “batting order bell D4”, the winning type “batting order bell D6”, the winning type “batting order bell D8”, the winning type “batting order bell D10”, and the winning type “batting order bell D12”, respectively.

During the RBB internal gaming state, the RBB operating non-internal gaming state, and the RBB operating during the RB internal medium gaming state, when the selection winning type is determined, it corresponds to the correct combination regardless of the operation mode of the player. Display the symbol combination on the active line A, and increase the expected number of coins per unit game to increase the RBB internal gaming state, RBB operating non-internal gaming state and RBB operating RB internal medium gaming state. It is considered that the selected winning type of the winning areas 26 to 37 is also duplicated in order to match the winning rate with the rip-in winning rate in the non-internal gaming state.

FIG. 14 is an explanatory diagram for explaining duplication of the winning area. FIG. 14 shows a simple copy of the groups of the winning areas 2 to 13 and the winning areas 26 to 37. That is, the selected winning type having the same property as the selected winning type consisting of the groups in the winning regions 2 to 13 is duplicated in the winning regions 14 to 25, and the selection winning type having the same property as the selected winning type consisting of the groups in the winning regions 26 to 37 is selected. The winning type is duplicated in the winning areas 38 to 49. Also in the selection winning types of the winning areas 14 to 25 and the winning areas 38 to 49, since the winning probability of incorrect answer is halved when the batting order is a batting order pair of the batting order which is the correct operating mode, the answer is correct. For the batting orders 1 to 6, which are the operation modes, groups in which correct answer pairs are formed are required.

Then, using the winning area thus increased, in the non-internal gaming state, the correct winning combination is won only when the operation in the correct operation mode is performed for all the selected winning types in the winning areas 2 to 49. In the RBB internal playing state, RBB operating non-internal gaming state and RBB operating in the RB internal playing state, the operation according to the correct operation mode is performed for the selected winning types of the winning areas 2 to 13 and the winning areas 26 to 37. Only when the winning combination is won, the correct winning combination is won, but for the selection winning type of the winning areas 14 to 25 and the winning areas 38 to 49, the stop control is changed and the winning combination " 100% of any one of "Small Win 1" to "Small Win 4" is won. In this way, when the selected winning type of the winning areas 14 to 25 and the winning areas 38 to 49 is won, in the non-internal gaming state, the adjusted expected number of coins per unit game is 2.75. , RBB inside playing state, RBB working non-internal playing state and RBB working RBB inside playing state, 15 sheets. Therefore, it is possible to set a high expected acquisition number per unit game in the RBB internal gaming state, the RBB operating non-internal gaming state, and the RBB operating RBB internal gaming state. The difference in the expected number of coins per unit game can be derived by multiplying the probability that any of the winning regions 14 to 25 and the winning regions 38 to 49 is determined by 12.3 (15 to 2.75). Therefore, it can be understood that the expected number of coins to be won per unit game can be adjusted by adjusting the probability that any of the winning areas 14 to 25 and the winning areas 38 to 49 is determined.

However, in the win type lottery table of FIG. 14, win areas 26 to 37 are provided for the win areas 2 to 13 in order to reduce the payout rate, and the win area is duplicated for each group. Therefore, it is necessary to provide 48 winning areas extending from the winning areas 2 to 49. This causes an increase in the area occupied by the main ROM 200b and the main RAM 200c. In particular, if the game state control means 312 manages the transition of the effect state, the winning area cannot be increased easily. Therefore, the duplication mode of the winning area is devised to suppress an increase in the occupied area of the main ROM 200b and the main RAM 200c.

For example, referring to FIG. 14, regarding the winning areas 14 to 25 and the winning areas 38 to 49, in the RBB internal middle gaming state, the RBB operating non-internal gaming state and the RBB operating RB internal medium playing state, the player's The payout number is 15 regardless of the operation mode. Therefore, in the RBB internal gaming state, the RBB operating non-internal gaming state and the RBB operating RB internal gaming state, the winning regions 14 to 25 and the winning regions 38 to 49 have the same function. In other words, in the RBB internal gaming state, RBB operating non-internal gaming state and RBB operating RB internal medium gaming state, one of the winning regions 14 to 25 and the winning regions 38 to 49 can fulfill its function. In this case, it is not necessary to set the other winning area.

FIG. 15 is an explanatory diagram for explaining aggregation of winning areas. For example, the number of wins in each of the win areas 2 to 13 in FIG. 14 is 2146, the number of wins in each of the win areas 14 to 25 is 143, and the number of wins in each of the win areas 26 to 37 is 716. It is assumed that the number of entries in each of the winning areas 38 to 49 is 47. Here, as shown in FIG. 15, the RBB internal gaming state of the winning regions 14 to 25 and the winning regions 38 to 49, the RBB operating non-internal gaming state, and the RBB operating mid-RB internal gaming state (specific gaming state) Functions of the winning areas 14 to 25 are aggregated (a group corresponding to the winning areas 14 to 25 is not provided), the number of each winning area of the winning areas 2 to 13 (first group) is 2099, and the winning area 14 to It is assumed that the numbers of 25 (third group) winning regions are reset to 190 and the numbers of winning regions 26 to 37 (second group) are reset to 763. Even with such a change, the ratio of the total number of duplicated winning regions to the total number of winning regions of the entire selected winning type is approximately equal to 2862:190. In other words, it is possible to perform the function of duplicating the winning area without duplicating only one of the two winning areas to be duplicated and copying the other. Specifically, in the RBB internal gaming state, RBB operating non-internal gaming state and RBB operating RB internal gaming state (specific gaming state), the payout number is 15 regardless of the operation mode of the player. When it is desired to set the ratio of the winning area to a% of the whole, the total number of units of the third group/(the total number of units of the first group+the total number of units of the second group) may be set to a. Therefore, the increase in the memory capacity due to the duplication of the winning area can be limited to 1.5 times, not double. In this way, the winning type lottery table is configured as shown in FIG.

Here, the winning areas 38 to 49 of the winning areas 14 to 25 and the winning areas 38 to 49 are deleted and only the winning areas 14 to 25 are left, but the winning areas 14 to 25 are deleted. However, only the winning areas 38 to 49 may be left. However, it is more advantageous to leave the winning areas 14 to 25 as follows. That is, the total number of wins in each of the win areas 14 to 25 (first group and third group) is larger than the total number of wins in each of the win areas 26 to 37 (second group). Therefore, in the RBB internal gaming state, RBB operating non-internal gaming state and RBB operating RB internal gaming state (specific gaming state), regardless of the operation mode of the player, each of the winning areas to win the correct winning combination. Since the number of wins in the winning area can be adjusted from the large number range (for example, 0 to 27468), the expected number of wins per unit game can be set finely. In addition, here, as a specific game state in which only the winning areas 14 to 25 are left, a bonus game state, in particular, an RBB internal medium gaming state, an RBB operating non-internal game state, and an RBB operating medium RB internal medium gaming state are given. Although explained, any one or more of the non-internal gaming state, the RBB internal gaming state, the RBB operating non-internal gaming state, the RBB operating RB internal gaming state, and the RBB operating RB operating gaming state are targeted. It is possible to adopt various game states such as.

With such a configuration, it is possible to suppress the increase of the occupied area of the main ROM 200b and the main RAM 200c while realizing the duplication of the winning area.

In addition, in the winning type “Batting Order Navi”, in the RBB internal gaming state, the RBB operating non-internal gaming state, and the RBB operating in the RB internal gaming state, there is a 1/4 probability that the answer is correct regardless of the operation mode of the player. If it is desired to win the winning combination, the winning area is not duplicated, and all the winning areas 14 to 25 may be targeted. Similarly, the winning combination is won with a probability of 3/4 regardless of the operation mode of the player. If desired, the winning area may not be duplicated and all the winning areas 2 to 13 may be targeted. As described above, by adjusting the numbers of the winning regions of the three groups shown in FIG. 15, it is possible to finely adjust the payout rate.

In addition, here, the example in which the winning area is duplicated only in one group of the two groups and not duplicated in the other group has been described, but the number of target groups is not limited to this, and three or more groups are included. On the other hand, either one may be aggregated and the winning area may be duplicated only in one group and not duplicated in other groups.

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

(Main processing of main control board 200)
FIG. 16 is a flowchart showing the main processing of the main control board 200. Here, first, along with the main processing of the main control board 200, an outline of one game after initialization will be described, and then the details of each processing will be described. Further, here, the processing relating 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. Although detailed description is omitted, when each process is performed, the switches (the bet switch 116, the start switch 118, the stop switches 120a, 120b, 120c) 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 144 and the slot machine 100 is turned on, the initialization means 300 executes an initialization process in preparation for the start of a game. The initialization means 300 generates backup data as needed while the power is on, and holds the backup data in the main RAM 200c. Therefore, even if an unexpected power failure occurs, it is possible to restore the state before power failure by using the retained backup data in this initialization processing. For example, even if an unexpected power failure occurs during the rotation of the reel 110, it is started from the state where each reel 110 is rotating again after the returning operation. Therefore, in the initialization processing, basically, the main RAM 200c is not initialized (RAM clear).

(Step S200)
Subsequently, the bet means 302 bets a medal by the player operating the bet switch 116 or inserting the medal into the medal inserting section 114. The command transmission unit 316 also generates a closing command indicating that the operation has been performed, and transmits the generated closing command to the sub control board 202.

(Step S300)
Next, the winning type lottery means 304 validates the game start operation for the start switch 118, and shifts to the operation waiting state of the start switch 118. Here, the winning type lottery means 304 is at the time when the start switch 118 is operated from the winning type lottery random number updated by the random number generator 200d of the main control board 200 in response to the operation of the start switch 118 by the player. The random number of the winning type 1 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. 6, and the acquired winning type lottery random number is determined. It is determined which of the winning areas in the winning type lottery table corresponds to, and the winning type or the unwinning of the determined winning area is determined as the lottery result.

Further, the command transmitting means 316 generates a winning type command including the lottery result (winning type or unwinning) of the winning type lottery, the information on the gaming state, etc., after the lottery result is determined according to the operation of the start switch 118. Then, the generated win type command is transmitted to the sub control board 202.

(Step S400)
When the start switch 118 is operated, the reel control means 306 drives the stepping motor 152 to rotate the left reel 110a, the middle reel 110b, and the right reel 110c. In this reel rotation processing, when a predetermined time (for example, 4.1 seconds) has elapsed from the start of rotation of the left reel 110a, the middle reel 110b, and the right reel 110c in the previous game (wait), the left reel in the game. The rotation of 110a, the middle reel 110b, and the right reel 110c is started, and when all of the left reel 110a, the middle reel 110b, and the right reel 110c are rotated at a constant speed, the process is moved to step S500.

(Step S500)
Subsequently, when the reel control means 306 activates the stop switches 120a, 120b, 120c and accepts the operation of the stop switches 120a, 120b, 120c by the player, the left reel 110a, the middle reel 110b, the right corresponding to the operation. One of the reels 110c is stopped and controlled.

In addition, when any of the stop switches 120a, 120b, 120c is operated, the command transmitting unit 316 outputs a stop command (first stop command, second stop command, second stop command, or second stop command) indicating information on the operated stop switch 120a, 120b, 120c. A stop command and a third stop command are generated each time the operation is performed, and the generated stop commands are sequentially transmitted to the sub control board 202.

(Step S600)
Next, the determination means 308 determines which predetermined combination the symbol combination displayed on the activated line A shown in FIG. 3(b) corresponds to, and the game state of the game state is determined according to the symbol combination. Performs various processes required for changes and replays. Further, the command transmitting means 316 generates a winning command including the symbol combination displayed on the activated line A and the payout number of medals when the symbol combination corresponding to the small winning combination is displayed on the activated line A. , And sends the generated winning command to the sub-control board 202.

(Step S700)
Then, based on the determination result in step S600, when the symbol combination corresponding to the small winning combination is displayed on the activated line A, the payout control unit 310 executes the payout process of the medals corresponding to the small winning combination. When the symbol combination corresponding to the replay combination is displayed on the activated line A, a process for betting the next game is automatically executed. Further, the gaming state control means 312 shifts the gaming state from the RBB operating gaming state to the non-internal gaming state when a predetermined number of medals are paid out in the RBB operating gaming state. In this way, the payout control means 310 performs various processes corresponding to the symbol combination displayed on the activated line A, and ends the one game. Further, when the medal payout process is performed, the command transmitting unit 316 generates a payout command indicating that the medal payout process is performed, and transmits the generated payout command to the sub-control board 202.

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

The preferred embodiments of the present invention have been described above with reference to the accompanying drawings, but it goes without saying that the present invention is not limited to such embodiments. It is obvious to those skilled in the art that various alterations or modifications can be conceived within the scope of the claims, and it should be understood that these also belong to the technical scope of the present invention. To be done.

For example, in the above-described embodiment, the game state control unit 312 repeatedly and sequentially shifts the non-internal game state, the RBB internal medium game state, the RBB operating non-internal game state, and the RBB operating RB internal medium game state in order. Achieve AT state across the state, relatively shorten the number of stay games in the non-internal gaming state and RBB internal medium gaming state, and RBB operating non-internal gaming state and RBB operating RB internal medium gaming state By setting the number of stay games to be relatively long, the average lip-drawing-out rate can be set above the lower limit, and the lip-including rate can be made equal while reducing the lip-including rate. Explained. However, the mode of transition between the game state and the effect state is not limited to such a case, and various specifications can be adopted according to the payout rate. For example, the number of stay games in the non-internal game state and the RBB inside medium game state is made longer than the above example, while the number of stay games in the RBB operating non-internal game state and the RBB operating medium RB inside game state is described above. By making it shorter than the example, it is possible to increase the rate of balls extracted without lip.

For example, the game state control means 312 repeatedly and sequentially shifts the non-internal game state, the RBB internal medium game state, the RBB operating non-internal game state, and the RBB operating RB internal medium game state, which is the same as the above-mentioned example. , RBB internal gaming state, non-internal gaming state, RBB operating non-internal gaming state and RBB operating RB internal medium gaming state, the stay ratio is 5:5. In this way, the state of the RBB inside where the number of stay games has become longer is the main stay gaming state of the non-AT effect state, and the non-internal gaming state, the RBB is operating, the non-internal gaming state, and the RBB is operating. The gaming state may be the main stay gaming state of the AT effect state. In this case, for example, in the RBB inside game state (non-AT production state), when the transition to the AT production state is determined, the player is caused to display the symbol combination corresponding to the winning combination "RBB", and the game state. It is also possible to shift from the RBB internal game state to the RBB operating non-internal game state and shift the effect state from the non-AT effect state to the AT effect state.

Even with such a configuration, as in the above example, in the RBB operating gaming state (RBB operating non-internal gaming state, RBB operating RB internal gaming state, RBB operating RB operating gaming state), the winning probability of the replay combination is determined. Can be 0. Then, the RIP in-progress ball rate in the RBB operating game state, which is the main stay game state of the AT effect state, becomes the lip-extracted ball rate, and it is possible to reduce the lip-introduced ball rate to the lip-extracted ball rate. .. Therefore, even if all the gaming states are integrated, the lip-inserted payout rate can be reduced while maintaining the lower limit value of the lip-drawing-out payout rate, and the game performance can be improved. In addition, if the payout rate is 100% or more, even if the payout rate including the lip is the same, the lower the probability of winning the replay is, the lower the payout rate for the lip is. It is advantageous. Further, when designing the lip removal ball rate in the AT production state, the replay role itself does not win in the RBB operating gaming state in which the AT production state is supposed to stay for a long time, so the normal AT production state, interval production It is possible to easily design the payout rate of each state and the chance AT effect state, and the payout rate of the entire AT effect state via the interval effect state, and reduce the work load.

Further, in the above-described embodiment, the main control board 200 and the sub-control board 202 are arranged so as to share the function part for advancing the game, but the function part of the main control board 200 is provided in the sub-control board 202. Alternatively, the functional units of the sub-control board 202 may be provided on the main control board 200, or all the functional sections may be collectively provided on one control board.

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