TECHNICAL FIELD OF THE INVENTION
The present invention relates to a slot machine, and more particularly to a slot machine having a so-called stock function.
[0002]
[Prior art]
Generally, a slot machine includes a variable display device having a plurality of reels on which a plurality of types of symbols are drawn on an outer peripheral portion, and a prize is generated according to a display mode when rotation of each reel is stopped. Depending on the type of winning that has occurred, not only medals are paid out as valuable value, but also a special game state called a big bonus or a regular bonus (hereinafter collectively referred to simply as a bonus) is entered, The game proceeds in an advantageous state for the player.
[0003]
In order for the winning combination including the bonus to occur, it is necessary that the winning combination is won in the internal lottery performed in advance (usually, when the start lever is operated) and the corresponding winning flag is set. Here, the small winning combination flag (including replay) is valid only in the game, and the bonus winning flag is carried over to the next game or later unless a winning is achieved. Furthermore, a slot machine having a function of carrying over a plurality of bonus wins in an internal lottery performed in each game (hereinafter, a stock function) is also known (for example, see Patent Documents 1 to 4).

[Problems to be solved by the invention]
The winning of a bonus in a slot machine using the stock function described in Patent Documents 1 to 4 is to collectively set the entire carried number. For example, when it is necessary to perform control with reference to the winning status of each role such as reel stop control processing, it is necessary to confirm the entire bonus winning status where a plurality of winning combinations may be set collectively.
[0006]
On the other hand, older slot machines (though there are still many models) that do not have a stock function have only one bonus winning flag set, for example, for each of the big bonus and the regular bonus. It is. For this reason, the slot machine having the stock function is different from the slot machine having no stock function in various points, not limited to the presence or absence of the stock function.
[0007]
SUMMARY OF THE INVENTION The present invention provides a slot machine having a so-called stock function, in which slot winning information of a special prize can be smoothly set one by one, and a module can be easily shared with a slot machine having no stock function. The purpose is to provide the machine.
[0008]
[Means for Solving the Problems]
To achieve the above object, a slot machine according to the present invention
The game can be started by setting the number of bets for one game, and the display result of the variable display device is derived and displayed, thereby ending one game, and according to the display result of the variable display device. In a slot machine where a predetermined prize can be generated,
Prior determination means (steps S201, S202) for determining whether or not to allow the occurrence of the prize before the display result of the variable display device is derived and displayed;
When the occurrence of a special prize is permitted by the preliminary determination means, it is possible to set decision information indicating that the occurrence of the special prize is permitted, and carry over a plurality of the set decision information to the next game and subsequent games. Possible decision information carryover means (stock number storage unit 302);
Prize possible information setting means (winning flag setting unit 301) for setting prize possible information indicating that a prize can be generated for each type of prize;
When the prize-possible information of the special prize is not set in the prize-possible information setting means, the decision information carried over by the decision information carry-over means is transferred to the prize-possible information setting of the special prize. Means for setting information and erasing the transferred decision information from the decision information carryover means (steps S215, S216, S414, S415).
The winning information of the special winning is cleared when a special winning based on the winning information occurs.
It is characterized by the following.
[0009]
In the above-mentioned slot machine, when the decision information is carried over to the decision information setting means, and the prize possible information of the special prize is not set in the prize possible information setting means, the carried decision information is transferred as the prize possible information. . The prize possible information indicates only whether or not a special prize can be won, and does not indicate the number of carryovers, but can be set one by one without fail. The configuration of the prize-possible information set in the prize-possible information setting means is substantially the same as that in a slot machine without a so-called stock function, and a module for processing with reference to the prize-possible information is provided. And a slot machine having no stock function.
[0010]
In addition, when the prize other than the special prize is allowed to be generated by the predetermined means, the permission of the prize can be set as the prize possible information in the prize possible information setting means as it is.
[0011]
The above slot machine
Unavailable state control means (steps S213, S412) for controlling when the special prize winning information is set by the determination information transferring means to an impossible state in which a special prize based on the winning information cannot be generated. When,
An improper state canceling means (step S404) for canceling the improper state control by the improper state control means when a predetermined condition is satisfied can be further provided.
[0012]
In this case, it is possible to easily create a situation in which the decision information carry-over means carries over a plurality of pieces of special prize decision information, by determining the allowance of the occurrence of the special prize determined while being controlled to the impossible state. .
[0013]
In the above slot machine,
The winning possible information setting means is provided in a storage area (general work 112-2) which can be cleared by performing a specific operation,
The decision information carryover means may be provided in a storage area (special work 112-3) that cannot be cleared by performing the specific operation.
[0014]
Here, when the probability that the predetermined means allows the occurrence of a prize including the special prize changes according to a setting selected from a plurality of types of settings,
The specific operation may be an operation for selecting the setting.
[0015]
In this case, the number of pieces of decision information carried over as a result can be changed by, for example, a clerk of a game store performing a specific operation, so that a situation in which a desired number of pieces of decision information are carried over can be created. Further, since the operation of selecting the setting of the probability of allowing the occurrence of a prize is treated as a specific operation, it is not necessary to provide a special unit for clearing the prize possible information setting unit.
[0016]
Note that the probability that the predetermined means allows the plurality of types of special prizes to occur may be changed only for at least one type of prize (either special prize or other than special prize), and may be changed for all types of prize. do not have to. However, this does not preclude the case where all kinds of winnings change.
[0017]
In the above slot machine,
The special prize may include a plurality of types (a big bonus and a regular bonus) of different playability of a game state to be shifted by the occurrence of the prize. In this case,
The decision information carryover means can carry over the decision information for each type of the special prize,
The decision information transfer means includes a selection means (steps S214 and S413) for selecting a type of decision information to be transferred for setting the prize possible information, and transfers the type of decision information selected by the selection means. The prize possible information can be set in the prize possible information setting means.
[0018]
In this case, it is not necessary to accumulate the order determined in advance for each type of special prize, so that the processing load can be reduced. Also, since it is only necessary to store the number of pieces of decision information carried over, it is possible to reduce the storage capacity required for the decision information carrying means.
[0019]
When there are multiple types of special prize as described above,
The selection unit may select the type of the special prize at a ratio according to a probability that each of the plurality of types of the special prize is allowed to be generated by the predetermined unit.
[0020]
Here, in the case where the probability that the predetermined means allows the generation of the plurality of types of special winnings changes according to the setting selected from the plurality of types of settings,
The ratio at which the selection unit selects the type of the special prize may be included in a range of the ratio of the probability of occurrence of the plurality of types of special prize for each setting.
[0021]
The setting of the prize possible information is not biased to any kind of special prize, and the number of pieces of the decision information carried over is not biased to any kind of special prize. An appropriate ratio can be applied as a ratio for selecting the type of the special prize. An appropriate ratio can be applied by including the ratio for selecting the type of special winning and the ratio of the probability of occurrence of the plurality of types of special winning for each setting.
[0022]
If the probability of occurrence of a special prize changes for each type by a setting operation of a person having a specific authority, the selection unit changes the ratio of selecting the type of the special prize according to the change in the probability. It may be a thing. Note that the probability that the predetermined means allows the plurality of types of special prizes to occur need only change for at least one type of special prize, and does not need to change for all types of special prizes. However, this does not preclude changes in all kinds of special winnings.
[0023]
In the above slot machine,
The decision information carryover means may be capable of carrying over the special prize decision information permitted to be generated by the predetermination means up to a predetermined upper limit number.
[0024]
In this case, it is possible to prevent the player from excessively expecting a large number of special prizes to be generated in a short period of time, and to suppress the gambling to an appropriate range.
[0025]

The state in which the game has shifted to the big bonus is referred to as a second special game state, and a big bonus flag is set in the RAM 112 in the game control board 101.
[0059]
In addition, in a game other than the regular bonus game (including a case provided during the big bonus), when "watermelon" or "bell" is aligned on the activated line, or "cherry" appears on the left reel 3L. In this case, a small role prize is won. Except for the small role game provided during the big bonus period and the regular bonus game (including the inside of the big bonus), if “JAC” is aligned on the activated line, a replay prize is won.
[0060]
In addition, the replay winning is not a small role winning in a strict sense, but it is the same as other small role winning in that it does not involve the transition of the gaming state, so unless otherwise noted, in this embodiment, " In the case of "small role", this shall include replay. Also, JACIN for which a flag is set at the same position as in the replay at the time of the bonus, and JAC during the regular bonus are also included in the “small win”. In addition, a simple “bonus” includes both a big bonus and a regular bonus.
[0061]
If there is a winning in the role described above, a number of medals corresponding to each role will be paid out (except in the case of a replay winning). The corresponding number of credits are accumulated as data, and in this case, the valuable value is paid out in the same manner as the medal). The number of medals to be paid out is 15 in all, except that the small part of the bell is eight and the small part of the cherry is two.
[0062]
Next, a description will be given of the setting of the winning flag which enables the winning of each of the above-mentioned winning combinations. The winning flag of each winning combination is set in the RAM 112, while the small winning flag is set based on the result of the internal lottery. The bonus winning is temporarily stocked as a result of the internal lottery, and when the bonus winning flag is not set in the RAM 112, the stock is shifted from the stock and the bonus winning flag is set. The bonus winning stock is also stored in the RAM 112. Therefore, the description will be made from the RAM 112.
[0063]
FIG. 6 is a diagram showing a memory map of the RAM 112 of the game control board 101. As shown in the figure, the RAM 112 stores important work 112-1, general work 112-2, special work 112-3, set value work 112-4, non-save work 112-5, and unused area 112- as work areas. 6 and an unused stack area 112-7 and a used stack area 112-8 as stack areas. Each of the areas 112-1 to 112-8 is distinguished by a condition when the area is cleared, and FIG. 7 is a diagram showing conditions for clearing each of the areas 112-1 to 112-8 of the RAM 112.
[0064]
The important work 112-1 is a work area for storing data that may cause inconvenience if cleared at the end of the big bonus. The important work 112-1 is cleared only when the RAM 112 is broken when the power is turned on and when the setting by the setting switch 91 is completed. The general work 112-2 is a work area for storing data that may be cleared at the end of the big bonus, and includes a winning flag setting unit 301 described in detail below. Most of the flags indicating the gaming state and various counters are also stored here. The general work 112-2 is cleared when the RAM 112 is broken when the power is turned on and when the setting is completed, in addition to when the big bonus ends.
[0065]
The special work 112-3 is a work area for generating a command to be transmitted to the effect control board 102 and a software random number, and includes a stock number storage unit 302 described in detail later. The special work 112-3 is cleared only when the RAM 112 is broken when the power is turned on. The set value work 112-4 is a work area for holding the set value by the setting switch 91. When the setting is completed, the set value is replaced by data indicating the set value 1 when the RAM 112 is broken when the power is turned on. Can be put in. In other cases, no value is entered here. The unsaved work 112-5 is a work area that holds the state of the switch, and is cleared when the power is turned on, regardless of whether the RAM 112 is broken.
[0066]
The unused area 112-6 is an unused area of the RAM 112 and is used when power is turned on (regardless of whether the RAM 112 is broken), at the end of setting, at the end of the big bonus, and at the start of each game. Cleared. The unused stack area 112-7 is an unused area of the stack area, and is cleared under the same conditions as the unused area 112-6. The used stack area 112-8 is a used area of the stack area and is not cleared. Although the boundary between the unused stack area 112-7 and the used stack area 112-8 is variable, a stack pointer indicating this is provided in the used stack area 112-8.
[0067]
In the winning flag setting unit 301 provided in the general work 112-2, a setting area of a winning flag is provided by one bit for each type of combination described above. The replay winning flag in the normal gaming state or RT is used as both a JACIN winning flag at the time of the big bonus and a JAC winning flag at the time of the regular bonus. The configuration of the winning flag setting unit 301 is no different from the configuration of a slot machine without a stock function. The stock number storage unit 302 provided in the special work 112-3 stores the winning stock numbers of the big bonus and the regular bonus in 4 bits each, and the upper limit of the stock number that can be stored in each is 15. ing.
[0068]
Next, the internal lottery and bonus winning stock and their release will be described in further detail. The internal lottery is for determining in advance whether or not to win a prize in each of the roles described later. The random number for the internal lottery obtained using the hardware random number function for each game, the setting by the setting switch 91, the game By referring to the winning determination table prepared in the ROM 113 based on the number of bets set by the player and the current game state, the CPU 111 performs such means for such a pre-determination. Winning in the internal lottery is exclusive, and a plurality does not win simultaneously in one game.
[0069]
When the small combination is won, a winning flag corresponding to the winning combination in the game is set in the winning flag setting unit 301. If the JACIN is won during the big bonus, the JACIN winning flag (same position as the replay flag) is won. If the JAC is won during the regular bonus, the JAC winning flag (substantially the same position as the replay flag) is won. The flag is set in the flag setting unit 301. If the small winning combination flag is set in the winning flag setting unit 301, the corresponding small winning combination can be won. The small win flag is deleted at the end of each game, and is not carried over to the next game transition.
[0070]
When a big bonus or a regular bonus is won, the winning is temporarily stored in the stock number storage unit 302 until the upper limit of each stock number is reached. If no bonus winning flag of any kind is set in the winning flag setting unit 301, the stocked bonus winning is shifted, the corresponding bonus winning flag is set in the winning flag setting unit 301, and the stock number storage unit is stored. The bonus winning stock stored in 302 is decremented by one.
[0071]
However, even if the bonus winning flag is cleared by the bonus winning, the bonus winning stock at that time is not shifted as the bonus winning flag, but further bonus winning is stocked at the end of the bonus based on the bonus winning. Then, the bonus winnings stocked at that time are shifted as bonus winning flags. When shifting from bonus winning stock to the winning flag, if only one of the big bonus and regular bonus is stocked, the type of stock that is inevitably selected will be selected and shifted. If both are stocked, either is selected and shifted as described below.
[0072]
However, just because the bonus winning flag is set in the winning flag setting unit 301 by the shift from the stock described above, it does not mean that a bonus prize can be won. When the bonus winning flag is set in the winning flag setting unit 301, the gaming state is controlled to RT, a reel control table in which a bonus prize cannot be selected is selected, and stop control of the reels 3L, 3C, and 3R is performed. It is.
[0073]
The game state of the RT is released and the bonus prize is enabled when a predetermined game has elapsed since the game state was controlled to the RT, and the number of the RT punk games is large (for example, Either about 700 games) or a small number of games (eg, about 120 games) is selected when the bonus winning flag is set, and is set in the RT counter provided in the RAM 122. The value of the RT counter is decremented by one each time one game is played in the game state of RT, and when the value becomes 0, the game returns to the normal game state.
[0074]
In this way, even if the game state is controlled to RT and the bonus prize is not possible, the bonus prize can be won in the internal lottery even in the game while the bonus prize is not possible, and the bonus prize is stocked. When the number of RT puncture games is exhausted and the game returns to the normal game state, a reel control table capable of winning a bonus is selected. Therefore, a bonus is won based on the bonus winning flag set in the winning flag setting unit 301. It becomes possible.
[0075]
As the above-mentioned winning determination table for determining the winning probability for each role is selected depending on the gaming state, the winning probability for each role changes depending on the gaming state. However, in the normal gaming state and the RT, the probability of replay winning changes only in a small range so as not to affect the progress of the game, and there is no difference in the winning probability for other roles. The RT is merely a gaming state that is used for convenience so as to prevent a bonus prize from being won using a reel control table different from a normal gaming state, thereby enabling a bonus winning stock.
[0076]
Further, since a different winning determination table is selected depending on the setting made by the setting switch 91, the winning probability of each role changes depending on the setting. FIG. 8 is a diagram showing, for each setting, the probability of winning the big bonus and the regular bonus when the gaming state is normal or RT. The winning probability of the regular bonus is 1/655 regardless of the setting difference. On the other hand, the winning probability of the big bonus is 1/364 in the setting 1, 1/341 in the setting 2, 1/321 in the setting 3, 1/298 in the setting 4, and 1/278 in the setting 5. In the case of 6, it is 1/25.
[0077]
When both the big bonus and the regular bonus are stocked, which type of bonus winning is shifted from the stock and set as the bonus winning flag in the winning flag setting unit 301 is determined by the winning probability for each setting. Will be selected at a ratio corresponding to. When shifting the bonus winning from the stock, the big bonus and the regular bonus are respectively selected at a predetermined ratio within the range of 252: 655 to 364: 655 by extracting a random number, for example.
[0078]
Note that the winning probability of the small role also changes depending on the setting by the setting switch 91. However, the winning probabilities of all types of small wins do not have to be changed by the setting of the setting switch 91. Only the winning probability of the small role may be changed by the setting, and the winning probability of the big bonus or the regular bonus may not be changed by the setting. However, the winning probability of the small role is irrelevant to the present invention, and a detailed description thereof will be omitted.
[0079]
Hereinafter, a gaming operation in the slot machine 1 according to the embodiment will be described. In the following description, the term "game" includes a series of steps from setting the number of bets to rotating / stopping the reels 3L, 3C and 3R. Furthermore, if some processing (for example, payout of medals or transition of the game state) is performed after the rotation of the reels 3L, 3C, 3R is stopped, this processing is also included as processing in one game. I do.
[0080]
FIG. 9 is a flowchart showing processing for one game executed by the CPU 111 of the game control board 101. This process is also performed after the power is turned on and a predetermined boot process is performed, or immediately after the setting is changed by operating the setting switch 91. When the process of one game is started, first, an initial process including a process of clearing a predetermined area of the RAM 112 is performed (step S1). The details of the initial processing will be described later.
[0081]
Next, the number of bets is set by operating the single BET button 14 or the MAXBET button 15 or by inserting medals through the medal insertion slot 13 and operating the start lever 11 to substantially execute the game. A BET process for instructing start is performed (step S2). However, if a replay has been won in the previous game, the same bet amount as in the previous game is automatically set by the replay flag (the replay flag is deleted at this stage), so the start lever 11 is operated as it is. To start the game.
[0082]
When the number of bets is set by the BET process and the start lever 11 is operated, a lottery process is performed to determine whether or not the winning of each combination is permitted (step S3). In this lottery process, a small role winning flag is set based on each lottery result, and bonus winning is stocked. If the bonus winning flag is not set while the bonus winning is stocked, the bonus winning flag is set. In addition, the control of the game state to the RT for preventing a predetermined number of games from winning a bonus after setting the bonus winning flag is also performed. The details of the lottery process will be described later.
[0083]
When the lottery process ends, a reel change start process is performed next (step S4). In the reel fluctuation start process, the reels 3L, 3C, and 3R in the previous game are rotated on the condition that a predetermined time (for example, 4.1 seconds) has elapsed since the time counted by one game timer has elapsed. The motors 3ML, 3MC, and 3MR are driven to start rotating all the left, middle, and right reels 3L, 3C, and 3R. Thereby, the symbol is variably displayed on the variable display device 2. If the predetermined time has not elapsed from the start of the rotation in the previous game, the game waits for the start of rotation, and turns on the weight lamp 61 to notify the weight display unit 31 of that fact. The order in which the reels 3L, 3C, 3R are started to rotate may be changed according to the state of various flags set in the RAM 112. At the start of rotation, a reel stop timer and a one-game timer for the next game are started.
[0084]
Thereafter, reel fluctuation stop processing is performed (step S5). In the reel fluctuation stop process, after a predetermined condition (detecting the reference position by the reel sensors 3SL, 3SC, and 3SR after the rotation speed reaches a certain speed) from the start of rotation of the reel is satisfied, the stop buttons 12L and 12C are set. , 12R, and the reel motors 3ML, 3MC, 3MR are stopped and the rotation of the reels 3L, 3C, 3R is stopped by being operated by the player. Further, when the time measured by the reel stop timer elapses a predetermined time (for example, 30 seconds), the driving of the reels 3L, 3C, 3R is forcibly stopped.
[0085]
At this time, with reference to the reel control table corresponding to the game state set in the RAM 112, the drive stop of the reels 3L, 3C, 3R is controlled in accordance with the setting status of the winning flag of each role of the winning flag setting unit 301. I do. In the reel control table referred to in the game state of the RT, even if the winning flag setting unit 301 sets the bonus winning flag, no bonus prize is generated.
[0086]
When the driving of the reels 3L, 3C, and 3R is stopped, it is determined whether any of the above-mentioned winning symbols is aligned on the activated line corresponding to the bet number set in the BET processing in step S2 in the display mode at the time of the stop. A winning determination process is performed (step S6). If it is determined in this winning determination process that one of the winning combinations is won, various processes corresponding to the winning generated on the game control board 101 are performed, and various processes not related to the winning are also performed. The details of the winning determination process will be described later.
[0087]
When the winning determination process is completed, a payout process is performed, and the credit is increased by the number of expected payout medals set in the winning determination process. However, when the number of credits accumulated as data reaches 50, the hopper motor 82 is driven to pay out an excess number of medals from the medal payout opening 71 (step S7). Then, the processing for one game ends, and the processing for the next one game starts. In the case where the number of tokens to be paid out is not set in the winning determination processing, the payout processing is not performed.
[0088]
Next, the initial processing in step S1 will be described in detail. FIG. 10 is a flowchart showing in detail the initial processing executed by the CPU 111 in step S1. In the initial processing, it is first determined whether the power has been turned on by operating the main switch 94 immediately before (step S101). When the power is turned on immediately before, the state of the RAM 112 is checked to determine whether or not the data content is broken (step S102).
[0089]
If the RAM 112 is not broken, only the unsaved work 112-5 is cleared (step S103), and the process proceeds to step S108. If the RAM 112 is broken, the important work 112-1, the general work 112-2, the special work 112-3, and the unsaved work 112-5 are cleared, and the set value work 112-4 is set to 1 as the set value. Is entered (step S104), and the process proceeds to step S108.
[0090]
If the power has not been turned on immediately before in step S101, it is determined whether or not the setting of the internal winning probability has been changed by operating the setting switch 91 immediately before (step S105). If the setting has been changed, the important work 112-1 and the general work 112-2 are cleared (step S106). Further, the setting value changed by the operation is input to the setting value work 112-4 (step S107), and the process proceeds to step S108.
[0091]
If the setting has not been changed, the process directly proceeds to step S108. In step S108, the unused area 112-6 and the unused stack area 112-7 which are cleared under any conditions are cleared. Then, the initialization process is completed, and the process returns to the process of FIG. Regardless of the state immediately before the start of the initial processing, the used stack area 112-8 is not cleared in this initial processing.
[0092]
Next, the lottery process in step S3 will be described in detail. FIG. 11 is a flowchart showing the details of the lottery process executed by the CPU 111 in step S3. First, the random number for internal lottery generated by the random number generation circuit 115 is sampled and acquired by the sampling circuit 116, and the acquired value of the random number is temporarily stored in the RAM 112 (step S201). Next, the random number temporarily stored in the RAM 112 is set to the probability setting by the setting switch 91, the number of bets set in the bet processing in step S2, and the current game state (during normal, during RT, during big bonus, and during regular bonus). A comparison is made with the corresponding winning determination table (step S202).
[0093]
Next, by referring to the state of the bonus flag in the RAM 112, it is determined whether the current gaming state is a bonus (step S203). If the current gaming state is during the bonus, no further bonus is won and no bonus winning stock is released. Therefore, the process directly proceeds to step S217 described later.
[0094]
If the current gaming state is not during the bonus, the random number is compared with the winning determination table in step S202, and it is determined whether or not the big bonus has been won (step S204). If the big bonus has been won, it is determined whether or not the big bonus stock number in the stock number storage unit 302 has already reached the upper limit number (step S205). If the number of big bonus stocks has not reached the upper limit, the number of big bonus stocks is incremented by 1 (step S206). Then, the process proceeds to step S210.
[0095]
As a result of comparing the random number with the winning determination table in step S202, if the big bonus has not been won, it is determined whether or not the regular bonus has been won (step S207). If the regular bonus has been won, it is determined whether the regular bonus stock number in the stock number storage unit 302 has already reached the upper limit number (step S208). If the regular bonus stock number has not reached the upper limit number, the regular bonus stock number is incremented by one (step S209). Then, the process proceeds to step S210.
[0096]
In step S210, it is determined with reference to the winning flag setting unit 301 whether or not a bonus is being won, that is, whether or not either the big bonus winning flag or the regular bonus winning flag is set. If the bonus is being won, the process proceeds to step S217. If the bonus is not being won, it is determined whether or not the winning of the big bonus or the regular bonus is stocked by referring to the stock number storage unit 302 (step S211). If none of the winnings are stocked, the process proceeds to step S217.
[0097]
If the bonus is not being won and at least one of the big bonus and the regular bonus is stocked, the number of RT punk games is determined to be either a large number of games or a small number of games by, for example, obtaining random numbers (step S212). Then, the determined number of RT games is set in the RT counter of the RAM 112 (step S213). With the setting of the number of RT games, the gaming state becomes RT from the current game, and a bonus prize cannot be made.
[0098]
Next, the type of the bonus to be released after the end of the RT among the stocked bonuses is determined to be either the big bonus or the regular bonus. Here, if only one of the big bonus and the regular bonus is stocked, the type of the stocked bonus is determined as the type to be released. If both are stocked, the type of bonus is determined such that, for example, by obtaining random numbers, release is performed at a ratio within the above range (step S214).
[0099]
When the type of the bonus to be released after the end of the RT is determined, a bonus winning flag corresponding to the determined type of the big bonus winning flag and the regular bonus winning flag is set in the winning flag setting unit 301 (step S215). ). Further, the number of the bonuses of the winning type stocked in the stock number storage unit 302 is reduced by 1 (step S216). Then, the process proceeds to step S217.
[0100]
In step S217, as a result of comparing the random number with the winning determination table in step S202, it is determined whether or not some kind of small win or replay has been won. If any type has been won, a winning flag corresponding to the winning combination is set in the RAM 112 (step S218). Then, the lottery process ends, and the process returns to the process of FIG. If no win has been won for any of the small wins and replays, the lottery process ends, and the process returns to the process of FIG.
[0101]
Next, the winning determination processing in step S6 will be described in detail. FIG. 12 is a flowchart showing details of the winning determination process executed by the CPU 111 in step S6. First, it is determined whether any of the symbols on the activated line set according to the number of bets has been completed (step S301). If no symbols are present, the process proceeds to step S304 described below. If any symbols are available, the winning flag in the RAM 112 is referred to, and it is determined whether or not the winning hand corresponding to the type of symbols has been won in the internal lottery in advance (step S302).
[0102]
If the combination corresponding to the symbols aligned on the activated line has not been internally won, the processing ends with an error. If the winning combination corresponding to the symbols arranged on the activated line has been internally won, the winning combination is won, and a winning-related process including various processes related to the winning is performed (step S303). In this prize-related processing, one, two or three bet lamps 54 to 58 corresponding to the activated line in which the prize has occurred are blinked, the big bonus winning flag is cleared when the big bonus is won, and the big bonus flag is displayed. Setting, clearing the regular bonus winning flag when the regular bonus is won, setting the flag during the regular bonus, setting the scheduled payout number when winning a role other than replay, and setting the replay flag when winning the replay included.
[0103]
In step S304, non-winning-related processes including various processes unrelated to whether or not a winning has occurred are performed. Details of the non-prize-related processing will be described later. When the non-winning-related process ends, the winning determination process ends, and the process returns to the process of FIG.
[0104]
FIG. 13 is a flowchart showing the non-winning-related process in step S304 in detail. In the non-winning-related processing, first, the small winning combination flag set in the winning flag setting unit 301 is deleted (step S401). Next, by referring to the state of the big bonus flag and the regular bonus flag in the RAM 112, it is determined whether or not the current gaming state is a bonus (step S402).
[0105]
If the current gaming state is not in bonus, the RT flag is further referred to the RAM 112 to determine whether the current gaming state is in RT, that is, whether the value of the RT counter is larger than 0. A determination is made (step S403). If the current gaming state is not even during the RT, the non-winning-related process is terminated and the process returns to the process of FIG.
[0106]
If the current gaming state is RT, the value of the RT counter is decremented by 1 (step S404). When the value of the RT counter becomes 0 in this manner, the game returns from the RT gaming state to the normal gaming state, and it is possible to generate a bonus winning based on the bonus winning flag set in the winning flag setting unit 301 from the next game. Become. Then, the non-winning-related process ends, and the process returns to the process of FIG.
[0107]
If the current gaming state is “bonus” in step S402, the number of digested games (eg, the number of small combination games and the The number of games in the regular bonus game is separately counted), and the number of winnings in the regular bonus game is counted (step S405). As a result, it is determined whether or not the end condition of the current bonus (excluding the regular bonus during the big bonus) is satisfied (step S406). If the current bonus ending condition is not satisfied, the non-winning-related process is ended, and the process returns to the process of FIG.
[0108]
If the current bonus end condition is satisfied, the bonus in-flag set in the RAM 112 is deleted (step S407). Also, it is determined here whether the big bonus end condition is satisfied (step S408). If the condition for terminating the regular bonus is satisfied instead of the big bonus, the process directly proceeds to step S410. On the other hand, if the end condition of the big bonus is satisfied, the general work 112-2, the unused area 112-6, and the unused stack area 112-7 of the RAM 112 are cleared (step S409), and the process of step S410 is performed. Proceed to.
[0109]
In step S410, it is determined whether or not the winning of the big bonus or the regular bonus is stocked with reference to the stock number storage unit 302. If neither the big bonus nor the regular bonus is stocked, the non-winning-related process is terminated, and the process returns to the process of FIG.
[0110]
If at least one of the big bonus and the regular bonus is stocked, the number of RT punk games is determined to be either a large game or a small game, for example, by obtaining random numbers (step S411). Then, the determined number of RT games is set in the RT counter of the RAM 112 (step S412). With the setting of the number of RT games, the game state becomes RT from the next game, and it becomes impossible to win a bonus.
[0111]
Next, the type of the bonus to be released after the end of the RT among the stocked bonuses is determined to be either the big bonus or the regular bonus. Here, if only one of the big bonus and the regular bonus is stocked, the type of the stocked bonus is determined as the type to be released. If both are stocked, the type of bonus is determined such that, for example, by obtaining random numbers, release is performed at a ratio within the above range (step S413).
[0112]
When the type of the bonus to be released after the end of the RT is determined, a bonus winning flag corresponding to the determined type of the big bonus winning flag and the regular bonus winning flag is set in the winning flag setting unit 301 (step S414). ). Further, the number of the winning bonuses stored in the stock number storage unit 302 is decremented by one (step S415). Then, the non-winning-related process ends, and the process returns to the process of FIG.
[0113]
In the repetition of the game as described above, the CPU 111 of the game control board 101 performs the transition of the game state between the normal game state, the regular bonus, and the big bonus, and controls the production of the command according to the progress of the game. The signal is transmitted to the substrate 102. On the other hand, the CPU 121 of the effect control board 102 performs an effect by a unique process based on the command received from the game control board 101. The effect performed by the effect control board 102 is not particularly related to the present invention, and thus a detailed description is omitted.
[0114]
As described above, in the slot machine 1 according to this embodiment, when a bonus is won in the internal lottery, the bonus is temporarily stored in the stock number storage unit 302. When the bonus win is stocked in the stock number storage unit 302 and the bonus win flag is not set in the win flag setting unit 301, the bonus win is shifted from the stock number storage unit 302 and the win flag setting unit 301 is set. Is set with a bonus winning flag.
[0115]
By employing such a method, the slot machine 1 according to the embodiment can surely set the winning flag for each of the big bonus and the regular bonus. Further, since the bonus winning flag can be set one by one, the configuration of the winning flag setting unit 301 is no different from that of the slot machine without the stock function. For this reason, in processing (for example, reel fluctuation stop processing) in which it is necessary to refer to the setting status of the winning flag, it is possible to use a program module common to a program module used in a slot machine without a stock function. become. As a result, it is possible to reduce development man-hours and development costs.
[0116]
The shift of the bonus winnings stored in the stock number storage unit 302 to the winning flag setting unit 301 is performed when the bonus winning flag is not set in a normal gaming state such as when the slot machine 1 is operated or when the gaming state is set. It is to be performed when the bonus is over. Therefore, it is not complicated to determine the timing of shifting the bonus winning.
[0117]
Even if the bonus winning is shifted and the bonus winning flag is set in the winning flag setting unit 301, the game state is controlled to the RT where the bonus prize cannot be generated during the predetermined number of games. During this RT period, the bonus is won in the same manner as in the normal gaming state, so that the stock winning storage unit 302 can easily stock the bonus winning. Although there is a control in which the bonus prize cannot be won during the RT period, the first bonus winning from the start of the operation is immediately set as the bonus winning flag, so that the customer attendance at the time of introducing the hall unique to the stock machine deteriorates. The disadvantage is that it does not become too large.
[0118]
In the slot machine 1, the winning flag setting unit 301 and the stock number storage unit 302 are completely separated from each other. The former is stored in the general work 112-2, and the latter is stored in the special work 112-3. It is something to be done. The special work 112-3 is not cleared by operating the setting switch 91, but the general work 112-2 is cleared by operating the setting switch 91. When the general work 112-2 is cleared by operating the setting switch 91, the bonus winning flag of the winning flag setting unit 301 is deleted. Therefore, in the next game, the bonus flag is always sent from the stock number storage unit 302 to the winning flag setting unit 301. Will be shifted. As a result, the desired bonus winning stock status can be created by using the operation of the setting switch 91 in the game arcade.
[0119]
By the way, when a bonus is won in the internal lottery, the stock is stored in the stock number storage unit 302 separately from the big bonus and the regular bonus. Whether to shift to the unit 301 is determined at the time of the shift. Therefore, it is not necessary to accumulate the order of stocking for each type of bonus, and the processing load can be reduced and the storage capacity required for the stock number storage unit 302 can be minimized.
[0120]
However, when the bonus winnings stored in the stock number storage unit 302 are shifted to the winning flag setting unit 301, the ratio of the types of bonuses to be shifted depends on (approximately) the ratio in the internal lottery. I have. As a result, the bonus winning flag is set biased to one of the big bonus and the regular bonus, and the bonus prize is not won. Also, the number of stocks for winning the bonus is not biased to any type. Since this ratio is within the range of the ratio in the internal lottery from setting 1 to setting 6, an appropriate ratio can be applied.
[0121]
Further, the number of bonus wins stored in the stock number storage unit 302 has an upper limit of 15 for both the big bonus and the regular bonus. For this reason, the expectation that the stock of the bonus winning is continuously released is not excessively increased, and the gambling can be suppressed within an appropriate range. As a result, the ambition of the player is not instigated.

On the other hand, when setting the bonus winning flag in the winning flag setting unit 301, the RT punk lottery probability is determined to be either a high probability or a low probability, and the RT punk lottery is performed in each game during RT with the determined probability. , And the game state may be controlled to RT until a winning is made to disable the bonus prize, thereby realizing the stock function of the bonus winning. Further, depending on the timing of shifting the bonus winning from the stock number storage unit 302 to the winning flag setting unit 301, the stock function can be realized without using a special game state such as RT.
[0128]
