Description

  The present invention relates to a slot machine capable of generating a predetermined winning according to a display result of a variable display device capable of variably displaying a plurality of types of symbols each identifiable.

  The slot machine generally includes a variable display device having a plurality of reels having a plurality of types of identification information drawn on the outer periphery, and each reel starts to rotate by operating a start lever. Further, when the player operates a stop button provided corresponding to each reel, the rotation of the corresponding reel is stopped. A winning is generated according to the display result derived when the rotation of all reels is stopped.

  Also, in this type of slot machine, an internal lottery that determines whether or not to generate a prize in advance (usually at the time of start operation) is performed, and on the condition that this internal lottery is won, It is allowed to derive a corresponding display result.

  On the other hand, in this type of slot machine, in order to generate different types of winnings without increasing the types of symbols, there has been proposed one in which a winning corresponding to a certain symbol combination is varied according to the gaming state. Yes. For example, when a combination of “JAC-JAC-JAC” is prepared, in a normal gaming state, a combination of a replay winning combination that allows a player to play a game without newly using a gaming value such as a medal In the regular bonus, it is determined as a JAC winning, and in the big bonus, it is determined as a JACIN winning that triggers the transition to the regular bonus (for example, see Patent Document 1).

  In the internal lottery described above, random numbers for internal lottery that are regularly updated by hardware or software are extracted, and the value of the extracted random numbers is used for winning determination prepared according to the set value, the number of bets, and the gaming state. By comparing the tables, it is determined whether or not a winning determined according to the gaming state is won. The winning probability of each combination in the internal lottery may be different depending on the set value or the number of bets, but may be the same even if the set value or the number of bets is different. In the latter case, if all kinds of winning judgment values are registered in advance in the winning judgment table for each set value and the number of bets, there is a problem that the amount of data increases.

  In addition, as in the slot machine described in Patent Document 1, even if the same symbol combination is prepared, even if the slot machines having different types of winnings according to the gaming state, that is, the same symbol combination is prepared, the gaming state In slot machines with different contents (values to be given, etc.) depending on the game, the meaning of these common symbol combinations becomes complicated, making it difficult for players to understand was there.

  The present invention has been made paying attention to such problems, and suppresses the data amount of the judgment value data necessary for determining whether or not winning is allowed (so-called internal lottery), It is an object of the present invention to provide a slot machine that makes it possible to easily understand the difference in the types of winnings even when a plurality of winnings are configured using a common symbol.

In order to solve the above-described problem, a slot machine according to claim 1 of the present invention provides:
A variable display device comprising three or more variable display units capable of variably displaying a plurality of types of symbols each identifiable, each variable display unit being capable of deriving independent display results,

It is characterized by that.
According to this feature, the determination value data storage means stores determination value data in common for a plurality of types of allowable stages for any one or more types of winnings. With respect to one or more types of winnings in which determination value data is stored in common, the storage capacity required for storing determination value data can be reduced. That is, it is possible to reduce the data amount of the judgment value data necessary for determining whether or not winning is allowed. Further, when a specific symbol is derived on the winning line in all the variable display portions in the first gaming state, it is determined as the first winning, and at least one variable display among the variable display portions in the second gaming state. When a specific symbol is derived on the winning line in the portion and a symbol other than the specific symbol is derived on the winning line in at least one of the remaining variable display portions, it is determined as the second winning. Therefore, even when multiple types of winnings are generated using common specific symbols in different gaming states, the difference in each winning becomes clear, the difference between these winning types can be easily understood, When it is determined that the generation of the second prize is permitted, a special display as much as possible is provided except for the variable display section in which symbols other than the specific symbol are derived on the winning line. Since symbols are derived in the winning line, it easy to understand that a combination of symbols constituting the second prize was derived on the winning line.
Note that the predetermined number of bets is at least one bet number, and a game can be started by setting a bet number of two or more or setting a maximum bet number. good.
Further, storing the judgment value data individually according to the types of allowable stages does not necessarily mean that the judgment value data is stored individually for the number of types of allowable stages. If the judgment value data is not stored in common, the data is included in this. For example, when there are six types of allowable stages (first to sixth stages), the determination value data is also allowed in the case where the first to third stages are common and the fourth to sixth stages are common. Depending on the type, it is stored separately.
In addition, when the type of winning is determined for each gaming state, the allowance determining means stores the determination value stored in the determination value data storage means corresponding to the allowable stage set by the allowable stage setting means. According to the data, it may be determined whether or not the numerical value data for determination input in the determination area indicates that the occurrence is permitted for each type of winning determined for the gaming state. it can.
Further, the plurality of types of permissible steps that can be set by the permissible step setting means do not mean that the proportions at which the pre-determining means allows the occurrence of winnings must be different from each other in all types. It is only necessary that the permissible ratio in the types of the different types is different from the permissible ratio in the other types. However, it does not preclude being different in all types.

Judgment value data determines the probability that the pre-determining means decides to allow each prize to occur according to the allowable stage, but for development models, this judgment value data is finely adjusted. In general, the simulation is performed (the initial judgment value data may be different or may be the same). Appropriate judgment value data obtained as a result of simulation is applied to a model for mass production. Here, even if the judgment value data becomes the same regardless of the allowable stage as a result of performing the simulation while changing the judgment value data in accordance with the allowable stage, such a type of winning is still in the allowable stage. The determination value data may be stored individually according to the type of the. In addition, when the judgment value data is initially stored as the same number of judgment value data indicating the same judgment value individually according to the type of the permissible stage, the judgment value data that is initially registered according to the simulation result remains unchanged. If so, it can be stored in the determination value data storage means as it is as the same number of determination value data. When there is a problem with the judgment value data initially registered as a result of the simulation, the judgment value data can be changed in accordance with the allowable stage and stored in the judgment value data storage means as different number judgment value data.

  FIG. 3 is a diagram showing the configuration of the control circuit of the slot machine 1. As shown in the figure, the control circuit of the slot machine 1 is largely divided into a power supply board 100, a game control board 101, an effect control board 102, a reel relay board 103, a reel lamp relay board 104, an effect relay board 106, and an external output board 105. Separately configured.

  The power supply board 100 transforms an external power supply voltage of AC 100V and supplies operating power to the game control board 101 and other parts of the slot machine 1. In FIG. 3, only the game control board 101, the hopper 80, and the switches 91 to 94 are connected. However, the power supply board 101 also supplies power to other units. The power supply board 100 is provided in the slot machine 1 and is connected to a hopper 80 that includes a hopper motor 82 that performs a medal payout operation and a payout sensor 81 that detects a medal payout operation.

  The power supply board 100 sets a winning probability for an internal lottery to be described later, and a setting switch 91 and a setting switch 91 for changing setting values (setting 1 to setting 6) of medal payout rates calculated based on the probability. Are connected to a setting key switch 92 for enabling the operation, a second reset switch 93 for resetting the internal state (RAM 112), and a main switch 94 for switching the power ON / OFF, and detection of these switches. A signal is sent to the game control board 101. These switches 91 to 94 are provided inside the slot machine 1.

  The game control board 101 is a control board on the main side that controls the overall flow of the game in the slot machine 1, and includes a control unit 110 including a CPU 111, a RAM 112, a ROM 113, and an I / O port 114. It is installed. A random number generation circuit 115, a sampling circuit 116, and other circuits are mounted.

  The CPU 111 has an interrupt function (including an interrupt prohibition function) such as a timekeeping function and a timer interrupt, and executes a program (described later) stored in the ROM 113 to perform processing related to the progress of the game, and in the slot machine 1 Control each part of the control circuit directly or indirectly. The CPU 111 performs processing with 8 bits (1 byte) as 1. The RAM 112 is used as a work area when the CPU 111 executes a program. The ROM 113 stores programs executed by the CPU 111 and fixed data. The I / O port 114 inputs and outputs control signals to and from each circuit connected to the game control board 101.

  The RAM 112 uses a DRAM (Dynamic RAM) and requires a refresh operation to maintain the stored data contents. The CPU 111 is provided with a refresh register for performing this refresh operation. The refresh register is composed of 8 bits, and the lower 7 bits thereof are automatically incremented every time the CPU 111 fetches an instruction from the ROM 113, and the value is updated every execution time of one instruction.

  The random number generation circuit 115 is configured by a counter that counts up and updates the value every time a predetermined number of pulses are generated, as will be described later, and the sampling circuit 116 acquires the numerical value counted by the random number generation circuit 115. . The random number generation circuit 115 is provided for each type of random number used for the progress of the game, and a range of numerical values to be counted for each type of random number is determined. The CPU 111 sends an instruction to the sampling circuit 116 according to the processing to acquire the numerical value indicated by the random number generation circuit 115 as a random number (hereinafter, this function is referred to as a hardware random number function). Random numbers for internal lottery, which will be described later, are not used as they are extracted by the hardware random number function, but are processed and used by software. Details thereof will be described in detail.

  The CPU 111 also has a function of updating the numerical value of the specific address in the RAM 112 by timer interrupt processing and acquiring the updated numerical value as a random number (hereinafter, this function is referred to as a software random number function). The CPU 111 transmits various commands to the effect control board 102 via the I / O port 114. Each of these commands consists of 8 bits. Information (command) is sent from the game control board 101 to the effect control board 102 only in one direction, and no information (command) is sent from the effect control board 102 to the game control board 101. In addition, the effect control board 102 is connected to the game control board 101 via the effect relay board 106, and with this configuration, wiring connection between the game control board 101 and the effect control board 102 is facilitated. At the same time, by not directly connecting the game control board 101 and the effect control board 102, it is possible to prevent an illegal signal or the like from being directly input from the effect control board 102 to the game control board 101.

  Connected to the game control board 101 are a single BET switch 45, a MAXBET switch 46, a start switch 41, stop switches 42L, 42C, 42R, a settlement switch 47, a first reset switch 48, and a throw-in medal sensor 44. Detection signals from the switches / sensors are input. In addition, detection signals of the reel sensors 3SL, 3SC, and 3SR are input via the reel relay substrate 103. In accordance with the detection signals of these switches / sensors input via the I / O port 114 or the detection signals of various switches input via the power supply board 100 as described above, the CPU 111 on the game control board 101 Processing is in progress.

  The game control board 101 also includes a flow path switching solenoid 49, a game number display 51, a credit display 52, a payout display 53, a loading instruction lamp 59, a single betting lamp 54, two betting lamps 55, 56, Three betting lamps 57 and 58, a game over lamp 63, a start lamp 60, a replay lamp 62, BET button lamps 70a and 70b, and operation valid lamps 63L, 63C, and 63R are connected, and the CPU 111 follows the progress of the game. These operations are controlled.

  The game control board 101 is connected to reel motors 3ML, 3MC, and 3MR via a reel relay board 103. The CPU 111 refers to the reel control table corresponding to the gaming state in the ROM 113, controls the reel motors 3ML, 3MC, and 3ML via the reel relay board 103, and stops the reels 3L, 3C, and 3R.

  The effect control board 102 is a sub-side control board that controls the execution of effects in the slot machine 1, and is equipped with a control unit 120 including a one-chip microcomputer including a CPU 121, a RAM 122, a ROM 123, and an I / O port 124. Yes. In addition, the random number generation circuit 125 and the sampling circuit 126 are mounted, and the CPU 121 obtains the value counted by the random number generation circuit 125 by the sampling circuit 126, so that the hardware random number function similar to that of the game control board 101 is obtained. Is forming. It also has a software random number function by interrupt processing.

  The CPU 121 executes a program (described later) stored in the ROM 123 to perform processing related to the execution of the effect, and controls each circuit in the effect control board 102 and each circuit connected thereto. The performance is performed based on a command received from the game control board 101 via the I / O port 124. The RAM 122 is used as a work area when the CPU 121 executes a program. The ROM 123 stores programs executed by the CPU 121 and fixed data. The allocation of the addresses of the RAM 112 and the ROM 113 is different between the development model in the manufacturer and the mass production model delivered to the hall. The I / O port 124 inputs and outputs control signals to and from each circuit connected to the effect control board 102.

  The effect control board 102 is connected with game effect lamps 75A to 75M, a liquid crystal display 4, speakers 7L, 7R, and 7U, a fluorescent lamp 6, a weight lamp 61, and a bonus notification lamp 66. A reel lamp 3LP is connected via a reel lamp relay substrate 104. The control unit of the effect control board 102 performs these effects by controlling these parts.

  The reel relay board 103 relays between the game control board 101, the external output board 105 and the reel unit 3. The reel relay substrate 103 is also connected with a full sensor 90, and its detection signal is input. The full tank sensor 90 is provided inside the slot machine 1 and detects that the medals in the overflow tank storing the medals overflowed from the hopper 80 are full.

  The reel lamp relay board 104 relays between the effect control board 102 and the reel unit 3. The external output board 105 is connected to an external device such as a hall management computer, and receives a big bonus medium signal, a regular bonus medium signal, an RT signal, a reel input from the game control board 101 via the reel relay board 103. The control signal, stop switch signal, medal IN signal, and medal OUT signal are output to the external device.

  In the slot machine 1, the medal payout rate changes according to the set value, and the winning probability of the internal lottery described later is determined according to the set value. Hereinafter, a setting value changing operation using the setting switch 91 will be described.

  In order to change the setting value, it is necessary to turn on the power of the slot machine 1 by the main switch 94 after the setting key switch 92 is turned on. When the setting key switch 92 is turned on and the power is turned on, the setting value can be changed. When the setting switch 91 is operated during a period during which the setting value can be changed, the setting value is updated one by one (when the operation is further performed from the setting 6, the setting is returned to the setting 1). When the setting key switch 92 is turned OFF after the start lever 11 is operated, the set value that has been changed is stored in the setting value storage area.

  In the slot machine 1, a winning is awarded when the symbols are aligned on the active line set according to the number of bets of the variable display device 2. In order for a winning to occur, the internal winning flag of the combination needs to be set, and details thereof will be described later. At the time of winning a prize, medals are paid out, and the gaming state is changed with the winning. Hereinafter, based on FIG. 4, the “combination” determined as the winning will be described.

  In the normal gaming state, when a combination of “BAR-BAR-BAR” is aligned on the active line corresponding to the number of bets, a regular bonus is awarded, and the gaming state shifts to a regular bonus. The regular bonus game can be a game called a regular bonus game (JAC game). In the regular bonus game, the betting number that can be set during the regular bonus is limited to 1 on the active line with a relatively high probability (the active line is placed in the middle of each reel 3L, 3C, 3R. “Bell-any-other (1)”, “Bell-other (1) -any”, “any-bell-other (1)”, “other (1)”. ) -Bell-any "," any-other (1) -bell ", and" other (1) -any-bell "are combined to generate a JAC prize. “Any” corresponds to all symbols, and “other (1)” corresponds to symbols other than “bell”. That is, if the “bell” stops on the active line of any one reel and the symbols other than “bell” stop on the active line of at least one of the remaining reels, a JAC prize is generated. The regular bonus is ended when the regular bonus game is performed a predetermined number of times (for example, 12 times) or when a JAC prize is generated a predetermined number of times (for example, 8 times). While the game state is in the regular bonus, the regular bonus medium flag is set in the RAM 112 (including the case where it is provided during the big bonus described below).

  In the normal gaming state, when a combination of “7-7-7” is arranged on the active line corresponding to the number of bets, a big bonus is won and the gaming state shifts to the big bonus. In the big bonus, a game called a small role game can be played. In this small role game, “Plum-any-other (2)”, “Plum-other (2) -any”, “any-Plum-other (2)”, “other” are on the active line with a relatively high probability. A combination of “(2) -Plum-any”, “any-other (2) -Plum”, and “other (2) -any-Plum” results in a JACIN winning. “Any” corresponds to all symbols, and “other (2)” corresponds to symbols other than “plum”. That is, if “Plum” stops on the effective line of any one reel and a symbol other than “Plum” stops on the effective line of at least one of the remaining reels, a JACIN winning occurs. However, JACIN winnings occur on the condition that other target roles in the small role game are not aligned on the active line, and if other roles are aligned on the active line, the combination of JACIN winning prizes Even if they are aligned, it is invalid. When a JACIN winning occurs, the above-described regular bonus (JAC game) is provided. The big bonus ends when the number of medals paid out to the player during the period reaches a specified number. While the gaming state is the big bonus, the big bonus medium flag is set in the RAM 112.

  In the normal gaming state, when, for example, “7-7-BAR” is aligned on the active line corresponding to the number of bets, RT winning is achieved and the gaming state shifts to RT (Replay Time). In RT, the winning probability of replay in the internal lottery is higher than that in the normal gaming state, but the winning probabilities of other roles are the same as in the normal gaming state. RT is ended by digesting a predetermined number of games. While the gaming state is at RT, an RT flag is set in the RAM 112. In the present embodiment, when “7-7-BAR” is prepared, RT winning is achieved and the gaming state shifts to RT (Replay Time). When the combination of “cherry-any-any” is complete, or when the combination of “watermelon-watermelon-watermelon” is complete, the gaming state may be shifted to RT as an RT prize. That is, you may make it combine RT prize and the small role prize mentioned later. In this embodiment, as described later, on the condition that RT is won by internal lottery, “7-7-BAR”, that is, a combination of RT winnings is arranged on the active line according to the number of bets. However, a combination of RT prizes may be arranged when a big bonus or a regular bonus is won and a combination of the won big bonus or regular bonus cannot be arranged.

  In the following description, the term “bonus” includes a big bonus, a regular bonus, and RT unless otherwise specified. Also, regular bonuses, big bonuses, and RTs triggered by bonuses are more advantageous for the player than the normal gaming state. It will be low compared to the percentage of staying in the gaming state.

  In a game other than the regular bonus game, when a combination of “cherry-any-any” is arranged on the active line, that is, when “cherry” stops on the active line for the left reel 3L, “watermelon-watermelon- When the combination of “watermelon” is prepared or when the combination of “bell-bell-bell” is prepared, a small role winning is obtained. In addition, if the combination of “Plum-Plum-Plum” is on the active line, except for the small role game and regular bonus game (including during the Big Bonus) offered during the Big Bonus Period, Become. It should be noted that in the following description, a small combination includes all combinations other than replay, JAC, JACIN, and bonus unless otherwise specified. When other display modes are derived and displayed on the variable display device 2, no winning combination has been won, that is, the game is lost.

  When there is a JAC prize or a small part prize among the above-described combinations, the number of medals corresponding to each combination is paid out (however, depending on the combination until the number of credits reaches 50) A lot of credits are accumulated as data, and in this case, valuable value is paid out in the same way as medals). The number of medals to be paid out is 15 for JAC, 2 for cherry, 6 for watermelon, and 8 for bell. In the case of a replay winning, even if the player does not set the bet number from the medal or credit on hand in the next game, the same bet number as the current game is automatically set and the game can be started as it is. Become.

  Next, the internal lottery will be described. The internal lottery is to determine whether or not winnings to each combination described later is permitted before the display result of the variable display device 2 is derived and displayed (actually, when the start lever 11 is operated). , A random number for internal lottery acquired for each game (an integer from 0 to 16383), a set value set by the setting switch 91, a bet number set by the player, and a winning determination generated based on the current gaming state This is performed by the CPU 111 by referring to the work table. Winning in the internal lottery is exclusive, and a plurality of winnings are not won simultaneously in one game.

  First, the winning determination table used in the internal lottery will be described. In the slot machine 1 according to the present embodiment, the winning determination table is not prepared in advance for each set value, the number of bets and the game state, but the set value, the number of bets and the game state (these are collectively referred to as a game situation). Is generated for each game. However, since the types of combinations differ depending on the gaming state, a table according to gaming state in which the type of combination and the storage location of the number of determination values indicating the number of determination values to be won for each combination is prepared in advance. Yes.

  FIG. 5 is a diagram illustrating an example of the gaming state-specific table. The gaming state table shown in FIG. 5 is stored in the ROM 113 in advance. The table according to gaming state is a table in which a combination determined according to the gaming state and an address in which the number of determination values corresponding to each combination is stored. The number of determination values may be 256 or more, and cannot be stored for one word. Therefore, each determination value is registered using a storage area for two words.

  The number of determination values may be common regardless of the set value and the bet number, and may be different depending on the set value and / or bet number. When the number of judgment values is common regardless of the set value, a common flag for the set value is set (value is set to “1”), and the number of judgment values is common regardless of the number of bets Is set with a common flag for the betting number (BET number) (value is set to “1”). If the number of determination values is the same regardless of both the set value and the number of bets, both flags are set.

  FIG. 5A shows a table by gaming state that is referred to when the player is in the gaming state of a regular bonus (including a big bonus). In the regular bonus, only JAC is registered as an internal lottery target. In the regular bonus, only one bet is possible, so the number of determination values is common regardless of the number of bets, and in the slot machine 1 in this embodiment, it is common regardless of the set value. It has become a thing.

  FIG. 5B shows a table by gaming state that is referred to when the small bonus game in the big bonus is in the gaming state. In the big bonus, four types, JACIN, “Watermelon”, “Bell”, and “Cherry”, are registered as internal lotteries. The number of judgment values for any combination is the same regardless of the setting value. However, the number of judgment values for the “Watermelon” small part and the “Bell” small part does not change due to the difference in the setting value. However, the number of determination values differs depending on the number of bets.

  FIG. 5C shows a game state-specific table that is referred to when the game state is RT. In RT, six types of bonuses, a regular bonus, a “watermelon” small role, a “bell” small role, a “cherry” small role, and a replay are registered as internal lottery targets. For the big bonus and the regular bonus, the number of determination values differs depending on the set value and the number of bets. However, when the bet number is 1 or 2, the bet number is common regardless of the set value.

  For the “Watermelon” and “Bell” small roles, the number of determination values does not change due to a difference in setting values, but the number of determination values differs depending on the number of bets. For the small part of “Cherry”, the number of determination values does not change according to the number of bets, but the number of bets differs according to the set value. The number of replay determination values is common regardless of the set value and the number of bets.

  FIG. 5D shows a table by gaming state that is referred to when the player is in the normal gaming state. In the normal gaming state, seven types of bonuses, regular bonus, “watermelon”, “bell”, “cherry”, replay, and RT are registered as internal lottery targets. Has been. For the big bonus and the regular bonus, the number of determination values differs depending on the set value and the number of bets. However, when the bet number is 1 or 2, the bet number is common regardless of the set value.

  For the “Watermelon” and “Bell” small roles, the number of determination values does not change due to a difference in setting values, but the number of determination values differs depending on the number of bets. For the small part of “Cherry”, the number of determination values does not change according to the number of bets, but the number of bets differs according to the set value. The number of replay determination values is common regardless of the set value and the number of bets. The number of RT determination values is also common regardless of the set value and the number of bets.

  When the gaming state is in RT, the winning probabilities of other combinations in the internal lottery are the same as in the normal gaming state except that RT is not won repeatedly and the replay winning probability is high. For this reason, if the set value and the bet number are the same except for the replay, the address of the judgment value number registered in the table according to the gaming state referred to when the player is in the RT is referred when the player is in the normal gaming state. It is the same as the address of the number of judgment values registered in the gaming state table.

  FIG. 6 is a diagram illustrating a storage area for the number of determination values acquired based on the addresses registered in the gaming state table. The storage area for the number of determination values is provided in the RAM 112 for the development model and in the address area allocated to the ROM 113 for the mass production model. For example, the address ADD is an address that is referred to for the role of JAC in the regular bonus game state table, but since the number of determination values stored here is 16375, the winning of JAC is determined when the player is in the regular bonus. For this, 16375 is acquired as the number of determination values.

  Further, for example, the address ADD + 32 is an address that is referred to for the big bonus when the bet number is 3 and the set value is 6 in the normal gaming state or RT, but the number of determination values stored here is 60. When the bet number is 3 and the set value is 6 in the normal gaming state or RT, 60 is acquired as the determination value number for determining the winning of the big bonus. The addresses ADD + 74 and ADD + 76 are addresses that store the number of determination values for determining whether or not the replay is won in RT and the normal gaming state, respectively, but the number of determination values stored in the addresses is different from 5120 and 2245, respectively. Therefore, the replay winning probability in the normal gaming state is different from the replay winning probability in RT.

  FIG. 7 is a diagram illustrating an example of the winning determination table generated according to the set value, the bet number, and the gaming state. The winning determination table of FIG. 7 shows a table generated when the number of bets is 3 and the set value is 6 in the normal gaming state. The types of roles here are big bonus, regular bonus, “watermelon” small role, “bell” small role, “cherry” small role, replay, and RT. 30, 68, 3562, 269, 2245, 16 are acquired.

  In accordance with the number of acquired determination values, determination values that are determined to be winning for each combination are assigned. Here, each of 0 to 59, 60 to 89, 90 to 157 for Big Bonus, Regular Bonus, “Watermelon”, “Bell”, “Cherry”, Replay, and RT 158-3719, 3720-3988, 3989-6233, 6233-6249 are allocated. Losses are assigned to 6250 to 16383 as a result of the internal lottery.

  The approximate winning probabilities calculated for each combination based on this decision value allocation are big bonus, regular bonus, “watermelon” minor, “bell” minor, “cherry” minor, replay, and For each of RT, 1 / 273.1, 1 / 546.1, 1 / 240.9, 1 / 4.6, 1 / 60.9, 1 / 7.3, 1 / 10244.0 (decimal number 2 It is rounded off below. The winning determination table is stored in the work area of the RAM 112.

  Next, acquisition of random numbers for internal lottery will be described in detail. The random numbers for the internal lottery are acquired by extracting random numbers from the random number generation circuit 115 by the hardware random number function and processing them by software by the CPU 111. When acquiring a random number for internal lottery, a random number for determining notification for determining whether or not to turn on the bonus notification lamp 66 is also acquired. The least significant bit of the random number extracted from the random number generation circuit 115 or processed from the random number generation circuit 115 is called the 0th bit, and the most significant bit is called the 15th bit.

  First, extraction of random numbers from the random number generation circuit 115 will be described. FIG. 8A is a block diagram showing the configuration of the random number generation circuit 115 in detail. As shown in the figure, the random number generation circuit 115 includes a pulse generation circuit 115a, a lower counter 115b, and an upper counter 115c. The lower counter 115b and the upper counter 115c are both 8-bit (1 byte) counters, the lower counter 115b is the 0th bit to the 7th bit, and the upper counter 115c is a total of 16 bits from the 8th bit to the 15th bit. The data signal is output.

  The pulse generation circuit 115a outputs a pulse signal at a frequency that is higher than the frequency of the operation clock of the CPU 111 and is not an integral multiple thereof (preferably relatively prime). The pulse signal output from the pulse generation circuit 115a is clocked into the lower counter 115b.

  The lower counter 115b alternately inverts the 0th bit data signal between the H level and the L level every time a pulse signal is input from the pulse generation circuit 115a. Assuming that positive logic is applied, a logical value of H level corresponds to 1 and a logical value of L level corresponds to 0. In the case of negative logic, a logic value of 1 may be read as L level, and a logic value of 0 may be read as H level. When the level of the 0th bit data signal is inverted from H level to L level, that is, whenever the logic value of the 0th bit data signal changes from 1 to 0, the level of the 1st bit data signal is changed to H level. Inverted alternately with L level.

  Similarly, when the level of the (m−1) th bit data signal is inverted from the H level to the L level, that is, whenever the logic value of the (m−1) th bit data signal changes from 1 to 0, the mth bit data The signal level is alternately inverted between the H level and the L level. The carry signal is output every time the level of the seventh bit data signal changes from H level, that is, the logical value of the seventh bit data signal changes from 1 to 0. The carry signal output from the lower counter 115b is clocked into the upper counter 115c.

  The upper counter 115c alternately inverts the eighth bit data signal between the H level and the L level every time a carry signal is input from the lower counter 115b. Each time the level of the 9th bit data signal is inverted from H level to L level, the level of the 9th bit data signal is alternately inverted between H level and L level. Similarly, every time the level of the m−1th bit data signal is inverted from the H level to the L level, the level of the mth bit data signal is alternately inverted between the H level and the L level.

  The logic value of the 16-bit data signal in which the data signal of the lower counter 115b is the lower 8 bits and the data signal of the upper counter 115c is the upper 8 bits is 0 (0000h) every time the pulse generation circuit 115a outputs the pulse signal. ) → 1 (0001h) → 2 (0002h) →... → 65535 (FFFFh) The values are updated so as to be continuous every update, and the maximum value 65535 (FFFFh) is next to the initial value 0 (0000h). The value circulates and is output from the random number generation circuit 115.

  The sampling circuit 116 is configured by a latch circuit, and latches the 16-bit data signal output at that time from the random number generation circuit 115 based on a sampling command from the CPU 111 and outputs the latched data signal. The CPU 111 extracts numerical data corresponding to the data signal input from the sampling circuit 116 via the I / O port 114 as a random number generated by the random number generation circuit 115. In the following description, the data signal output from the random number generation circuit 115 is described as a random number corresponding to the logical value.

  Next, processing of random numbers extracted from the random number generation circuit 115 by software will be described. FIG. 8B is an explanatory diagram until the CPU 111 processes the random number extracted from the random number generation circuit 115 into a random number for internal lottery by software. The random number extracted from the random number generation circuit 115 is stored in a 16-bit general-purpose register 111GR included in the CPU 111.

  When the random number extracted from the random number generation circuit 115 is stored in the general-purpose register 111GR, the CPU 111 uses the other general-purpose register or the work area of the RAM 112 to lower byte of the general-purpose register 111GR (value extracted from the lower counter 115b). And the value of the upper byte (the value extracted from the upper counter 115c) are exchanged.

  Next, the CPU 111 performs a logical OR operation with the value 8080h of the random number obtained by exchanging the upper byte and the lower byte for the extracted random number. Since the processing word of the CPU 111 is 1 byte, the logical sum operation is actually performed sequentially on the upper byte and the lower byte. By this OR operation, the 15th bit and the 7th bit are always 1. Further, the CPU 111 shifts the upper 1 byte (8th bit to 15th bit) to the lower bit by bit, and inserts 1 into the empty 15th bit.

  The CPU 111 acquires the value stored in the general-purpose register 111GR at this time as a random number for internal lottery, stores it in a predetermined area of the RAM 112, and determines the determination value (actual value) of each combination registered in the winning determination table. Are sequentially compared with the upper limit judgment value only). Since the 15th and 14th bits of the random number for internal lottery are always 1, the random number for internal lottery is a random number having a size of 14 bits (16384), which is substantially 0 to 16383. It takes a value.

  Note that interrupts to the CPU 111 are prohibited during the period from the extraction of random numbers from the random number generation circuit 115 to the end of processing. This is to prevent the contents of the general-purpose register 111GR from being rewritten in the interrupt processing routine when an interrupt occurs to the CPU 111.

  Next, the reel control table distribution (reel control distribution process) will be described. The reel control table is a table that defines stop control patterns for the reels 3L, 3C, and 3R constituting the variable display device 2, and is stored in the ROM 213. The reel control table allocation is to determine the reel control table to be applied in the game after the internal lottery and before the display result of the variable display device 2 is derived, and according to the result of the internal lottery, the CPU 111 Is what you do.

  In the reel control table, stop control patterns for the reels 3L, 3C, and 3R constituting the variable display device 2 are determined as described above. Specifically, the number of drawn symbols is determined for each of the stopped states of the reels 3L, 3C, and 3R, the stopped symbols of the already stopped reels, and the stop timings of the reels 3L, 3C, and 3R.

  FIG. 9 is a diagram showing the control contents of the reel control table.

  The reel control table of table number 01 is a table for drawing a combination of “cherry-any-any” into an effective line within a maximum of 4 symbols, and is selected when a cherry is won. The reel control table of table number 02 is a table for drawing a combination of “watermelon-watermelon-watermelon” into an effective line within a maximum of 4 symbols, and is selected when a watermelon is won. The reel control table of table number 03 is a table for drawing a combination of “bell-bell-bell” into an effective line within a range of a maximum of 4 symbols, and is selected when a bell is won.

  The reel control table of table number 04 is a table for drawing a combination of “plum-plum-plum” into an effective line in a range of a maximum of 4 symbols, and is selected when a replay is won.

  The reel control table of table number 05 is a table for drawing the combination of “BAR-BAR-BAR” into the effective line within a maximum of 4 symbols, and is selected when the regular bonus is won.

  The reel control table of table number 06 is a table for drawing a combination of “7-7-7” into an active line within a maximum of 4 symbols, and is selected when a big bonus is won.

  The reel control table of table number 07 is a table for drawing the combination of “7-7-BAR” into the effective line within a maximum of 4 symbols, and is selected when the RT is won.

  In addition, the reel control table of table number 08 has a combination of “bell-bell-other (1)”, “bell-other (1) -bell”, “other (1) -bell-bell” with a maximum of 4 symbols. It is a table for drawing in the effective line in the range, and is selected when JAC is won. As described above, other (1) is a symbol other than “bell”.

  Specifically, when the reel control table having the table number 08 is selected, first, control is performed so that the “bell” is drawn on the effective line within a maximum of 4 symbols in the reel that stops first (hereinafter referred to as the first stop reel). Is done. As described above, in the regular bonus game subject to JAC winning, the number of bets that can be set is limited to 1, and the active line is a line for determining a symbol horizontally in the middle of each reel 3L, 3C, 3R. Therefore, the control for pulling the “bell” into the middle stage of the first stop reel is performed. When the “bell” is stopped on the effective line of the first stop reel, the “bell” is stopped at the first stop reel in the second stop reel (hereinafter referred to as the second stop reel). Pull-in control is performed so that the “bell” is drawn on the effective line within a range of a maximum of 4 symbols. Then, when the “bell” stops on the active line in the first stop reel and the second stop reel, the first stop reel and the second stop reel in the reel that stops last (hereinafter referred to as the third stop reel). In the stop reel, control is performed so that symbols other than “bell” are drawn on the active line where “bell” is stopped. For this reason, when the reel control table with the table number 08 is selected, the control is performed so that the “bell” is drawn on the same effective line in the first stop reel and the second stop reel, and “bell” is applied to the third stop reel. Control to draw the symbols other than is performed. Further, in this embodiment, as shown in FIG. 2, since the “bell” is arranged so as to be within the pull-in range (maximum 4 symbols) in all reels, the reel control table of table number 08 is selected. Then, the “bell” always stops at the first stop and the second stop reel, and the symbols other than “bell” stop at the third stop reel.

  The reel control table of table number 09 has a combination of “plum-plum-other (2)”, “plum-other (2) -plum”, and “other (2) -plum-plum” with a maximum of 4 symbols. It is a table for drawing in the effective line in the range, and is selected when JAC is won. As described above, other (2) is a symbol other than “Plum”.

  Specifically, when the reel control table having the table number 09 is selected, first, control is performed so that “plum” is drawn on the effective line in the range of a maximum of 4 symbols in the first stop reel. When “Plum” is stopped on the active line of the first stop reel, “Plum” is displayed on the active line where “Plum” is stopped on the first stop reel. Pull-in control is performed to pull in the range. When the “plum” is stopped on the same effective line in the first stop reel and the second stop reel, the “plum” is stopped in the first stop reel and the second stop reel in the third stop reel. Control is performed to draw symbols other than “plum” on the active line. Therefore, when the reel control table with the table number 09 is selected, as shown in FIGS. 10A to 10C, “Plum” is placed on the same effective line in the first stop reel and the second stop reel. Pull-in control is performed, and in the third stop reel, control other than “plum” is performed on the effective line where “plum” is stopped in the first stop reel and the second stop reel. Further, even when the reel control table of the table number 09 is selected, in the second stop reel, when “plum” cannot be drawn onto the active line where the “plum” of the first stop reel is stopped, for example, FIG. As shown in FIG. 10E, the first stop reel is the middle reel, the “plum” of the middle reel is stopped at the lower stage, and the effective line is limited to the lower stage, as shown in d). In addition, when the “plum” is stopped on the active line where the “plum” of the first stop reel is stopped in the second stop reel, the “cherry” stops and the combinations of the cherry winnings are aligned. As shown in FIG. 10 (f), when the next "plum" cannot be drawn by drawing within the pattern, even if the "plum" cannot be stopped on the active line where the "plum" of the first stop reel is stopped. , Control that does not draw the "cherry" on the effective line on is carried out. In this case, as shown in FIG. 10 (g), in the third stop reel, control is performed to draw “plum” onto the effective line where the “plum” of the first stop reel or the second stop reel is stopped. Is called.

  As described above, when the reel control table having the table number 09 is selected, the control is performed so that “plum” is drawn on the same effective line in the first stop reel and the second stop reel as much as possible. In the first stop reel and the second stop reel, control is performed so that symbols other than “plum” are drawn on the active line where “plum” is stopped. In the second stop reel, the “plum” of the first stop reel is controlled. When the “plum” cannot be drawn onto the active line where the “stop” is stopped, the “plum” is drawn onto the active line where the “plum” of the first stop reel or the second stop reel is stopped at the third stop reel. Control is performed. Further, in this embodiment, as shown in FIG. 2, since “Plum” is arranged within the pull-in range (maximum 4 symbols) in all reels, the reel control table with table number 09 is selected. Then, “Plum” always stops on the same active line in any two reels, and symbols other than “Plum” stop on the active line where “Plum” is stopped in the remaining reels. It will be.

  In addition, the reel control table of table number 10 is a table that draws a symbol so that the target combination in the regular bonus game, that is, the combination of JAC winning prizes is not aligned on the active line, and any combination in the regular bonus game is won. Selected when not.

  In addition, the reel control table of table number 11 is a table that draws a symbol so that the combination of the target role in the small role game, that is, the cherry winning, the watermelon winning, the bell winning, and the JACIN winning is not aligned on the effective line, It is selected when no winning combination is won in the small role game.

  In addition, the reel control table of table No. 12 has a combination of combinations of combinations that are targeted in the normal gaming state, that is, big bonus winning, regular bonus winning, RT winning, cherry winning, watermelon winning, bell winning, and replay winning. This is a table that draws symbols so that they are not aligned, and is selected when no combination is won in the normal gaming state.

  Next, stop control of the reels 3L, 3C, 3R constituting the variable display device 2 will be described. The reels 3L, 3C, 3R are stopped when the corresponding stop button 12L, 12C, 12R is operated and the stop condition is satisfied, respectively. Further, when the reel stop timer times a predetermined time, the respective stop conditions are sequentially satisfied, and the automatic stop mode is entered to stop the reel stop timer.

  When the reels 3L, 3C, and 3R are stopped by operating the stop buttons 12L, 12C, and 12R, the symbols that can be stopped within a maximum delay time of 190 milliseconds from the symbol position when the stop condition is satisfied. The symbol that is actually stopped is selected. During the maximum delay time of 190 milliseconds, it is possible to select up to 4 symbols and draw them on the active line, and select a symbol that does not become a winning display within the range of up to 4 symbols. Removal control can also be performed.

  In the reel control table, the number of drawn symbols is set so as to be within a range of a maximum of 4 symbols from the symbol position when all the stop conditions are satisfied as described above, and the reel 3L is operated by operating the stop buttons 12L, 12C, 12R. When stopping 3C and 3R, the reel control table is referred to, and the stop state of the reels 3L, 3C and 3R, the stop pattern of the already stopped reel, and the stop conditions of the reels 3L, 3C and 3R are established. A symbol to be actually stopped is selected based on the number of drawn symbols corresponding to the timing.

  In addition, in a game in which a winning flag for any combination is set, a reel control table that preferentially draws a symbol for a combination for which a winning flag is set is selected, so the stop buttons 12L, 12C, When the stop condition is satisfied by the operation of 12R, if the symbol of the combination for which the winning flag is set at the time of the operation is within a retractable range, it can be selected and derived on the active line. That is, if all of the stop buttons 12L, 12C, and 12R are operated before the reel stop timer measures a predetermined time, the display mode of the winning combination can be derived according to the operation timing. Even if one of the winning flags is set, if the symbol corresponding to the winning flag set in the range of the maximum delay time of 190 milliseconds cannot be selected, the loss in the range of the maximum delay time of 190 milliseconds is also performed. The symbols constituting the display mode are selected, and the display mode of the loss is derived.

  In addition, in a game in which no winning flag for any combination is set, a reel control table that draws a losing eye that does not have any target combination in the corresponding gaming state is selected, so that the stop buttons 12L, 12C, and 12R are selected. Even if the stop condition is satisfied by the operation of, if the winning flag of any combination is not set, the symbol constituting the display mode of the loss is selected in the range of the maximum delay time of 190 milliseconds The display mode of the loss is derived.

  When the stop condition is satisfied for all the reels 3L, 3C, and 3R because the reel stop timer has counted the predetermined time, the reel control table is not referred to regardless of which winning flag is set. , A symbol that does not constitute a winning display mode of any of the roles within the range of the maximum delay time of 190 milliseconds is selected and derived on the active line. In other words, the display mode of the loss is always derived.

  In addition, a part of the reels 3L, 3C, 3R has been stopped by operating the stop buttons 12L, 12C, 12R, and the reel stop timer has counted a predetermined time for the remaining part of the reels 3L, 3C, 12R. When the stop condition is satisfied for 3R, the winning display mode for any of the roles together with the symbols derived for some of the reels stopped within the range of the maximum delay time of 190 milliseconds without referring to the reel control table It is assumed that a symbol that does not constitute is selected and derived on the active line. In other words, the display mode of the loss is derived except when the winning display mode of “cherry” is derived when the reel 3L is stopped and the small part of “cherry” is derived.

  By the way, when even a part of the reels 3L, 3C, 3R is stopped by operating the stop buttons 12L, 12C, 12R, there is only a maximum of 4 symbols that can be pulled in. Depending on the display mode, it may be impossible to select a symbol that avoids deriving the display mode of the winning combination depending on the symbol position when the stop condition is established for the third stop reel. Become. A display mode in which derivation of the winning display mode cannot be avoided by the display mode when the second stop reel is stopped is referred to as a forbidden item.

  Here, regardless of whether or not the winning flag is set, when the stop condition of the third stop reel is satisfied by the reel stop timer counting a predetermined time, the display mode of the loss must be derived. . Therefore, when the first stop reel is stopped based on the operation of the stop button, the symbol is stopped according to the position when the stop condition is satisfied and the setting status of the winning flag (same as in the past). When the stopped first stop reel constitutes the prohibition eye and the second stop reel is stopped based on the operation of the stop button, stop control is performed so as not to derive the prohibition eye.

  However, if the tempering mode is not forbidden, the second stop reel is stopped by pull-in control up to a maximum of 4 symbols, and the tempering mode is derived and displayed as much as possible. Further, even when the already stopped first stop reel constitutes the prohibition eye, if the temperament mode other than the prohibition eye can be derived and displayed, control for deriving and displaying it is performed. When there are no symbols that can be tempered other than the prohibited eyes, the symbols to be stopped are selected so as not to derive the prohibited eyes, and the second stop reel is stopped.

  In all the reel control tables, the number of symbols for selecting a symbol that does not lead to the prohibition among the symbols that can be selected for the second stop reel as the number of drawn symbols for the stop control of the second stop reel. It has been established. For this reason, when the stop condition is established by the operation of the stop buttons 12L, 12C, and 12R, and the stop control of the second stop reel is performed, the forbidden eye can be derived among the symbols that can be selected for the second stop reel. The symbol to be stopped is selected from the symbols that are not present.

  Hereinafter, a gaming operation in the slot machine 1 in the present embodiment will be described. In the following description, in the case of “game”, in a narrow sense, it means from the operation of the start lever 11 to the stop of the reels 3L, 3C, 3R. However, when a game is played, the number of bets before the operation of the start lever 11 is set, and after the reels 3L, 3C, 3R are stopped, medals are paid out and the game state is shifted. Is also included in the “game” in a broad sense.

  FIG. 11 is a flowchart showing processing executed by the CPU 111 of the game control board 101.

  In this process, first, an initial process for preparing for a game start with the power-on is executed (step S1). Specifically, after a predetermined boot process is performed as the power is turned on, the game state is restored if it can be restored to the gaming state before the power is turned off. In addition, if it is impossible to return to the gaming state before the power is turned off, the gaming state is initialized.

  Next, the number of bets is set by operating one BET button 14 or MAXBET button 15 or by inserting medals from the medal insertion slot 13, and operating the start lever 11 to substantially change the game. A BET process for instructing the start is performed (step S2). However, if the player has won a replay in the previous game, the same number of bets as in the previous game are automatically set by the replay game flag (the replay game flag is erased at this stage). It only has to be operated to instruct the start of the game.

  When the bet amount is set by the BET process and the start lever 11 is operated, an internal lottery is performed to determine whether or not to allow a winning for each of the above combinations according to the set value, the bet number and the gaming state, A lottery process for setting a winning flag according to the result is performed (step S3). If the bonus winning flag has been carried over from the previous game, the bonus winning flag will not be set again, but the small role (including replay etc.) winning flag will be set redundantly. There is a case. Details of the lottery process will be described later.

  When the lottery process is completed, a reel control distribution process for selecting a reel control table applied in the game according to the game state and the setting state of the winning flag is performed (step S4). Details of the reel control distribution process will be described later.

  Next, reel fluctuation start processing is performed (step S5). In the reel fluctuation start process, the reels 3L, 3C, and 3R in the previous game are processed on the condition that a predetermined time (for example, 4.1 seconds) has elapsed from the start of rotation of the reels 3L, 3C, 3R The motors 3ML, 3MC, and 3MR are driven to start rotation of all the left, middle, and right reels 3L, 3C, and 3R. Thereby, the symbols are variably displayed on the variable display device 2. Here, when a predetermined time has not elapsed since the start of rotation in the previous game, the rotation is awaited for rotation, and the weight display unit 31 is notified by lighting the weight lamp 61. Also, the timing of one game timer for the next game is started.

  Thereafter, reel fluctuation stop processing is performed (step S6). In the reel fluctuation stop process, after a predetermined condition is established from the start of reel rotation (the reference position is detected by the reel sensors 3SL, 3SC, 3SR after the rotation speed reaches a certain speed), the stop buttons 12L, 12C , 12R is made effective, and the reel motors 3ML, 3MC, and 3MR are stopped by being operated by the player, and the rotation of the reels 3L, 3C, and 3R is stopped. At this time, in accordance with the reel control table set in the RAM 112, pull-in control or removal control is performed within a range of 4 symbols or less. Further, when the elapsed time after the predetermined condition is satisfied reaches a predetermined time (for example, 30 seconds), the driving of the reels 3L, 3C, and 3R is forcibly stopped as an automatic stop mode. Details of the reel fluctuation stop process will be described later.

  When the driving of the reels 3L, 3C, 3R is stopped, in the display mode at the time of stopping, whether any of the above-mentioned role symbols is derived and displayed on the active line according to the bet number set in the BET process in step S2 A winning determination process for determining whether or not is performed (step S7). If it is determined in this winning determination process that one of the winning combinations has been won, as processing corresponding to the winning that occurred on the game control board 101, setting of the number of medals to be paid out according to the winning combination, and the case of replay winning A replay game flag is set, a bonus winning flag is deleted when a bonus winning (including JACIN winning) and a bonus flag is set, an RT winning flag is deleted when an RT winning is set, and an RT flag is set. Details of the winning determination process will be described later.

  When the winning determination process ends, a payout process is performed (step S8). In the payout process, the credit is increased by the payout number 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 slot 71. In addition, various processes that are not related to winning, such as control of the end of the bonus, erasure of a small role (including replay) winning flag, and cancellation of the automatic stop mode are also performed. Then, the process for one game is completed, the process returns to step S2 again, and the process for the next one game is started.

  Next, the lottery process in step S3 will be described in detail. FIG. 12 is a flowchart showing in detail the lottery process executed by the CPU 111 in step S3. In the lottery process, first, a random number acquisition process whose details will be described later is performed. In this random number acquisition process, a random number value for internal lottery is acquired based on the random number generated by the random number generation circuit 115 (step S101). Furthermore, as the game situation of the current game, the current gaming state distinguished by the presence / absence of the setting of the big bonus medium flag, the regular bonus medium flag, or the RT flag, and the bet number set in the BET process of step S2 The currently set value is acquired and stored in the work area of the RAM 112 (step S102).

  Next, the setting state of the common flag is referred to as the processing target for the combinations registered in the gaming state table corresponding to the current gaming state (step S103). As a result, it is determined whether the common flag is set for both the set value and the BET number (step S104). If the common flag is set in any case, the number of judgment values stored at the address registered for the combination in the gaming state table is acquired and temporarily stored in the work area of the RAM 112 (step S105). Then, the process proceeds to step S107.

  On the other hand, if the common flag is not set, the determination value number stored in the address registered in the table according to the gaming state corresponding to the current setting value and the betting number acquired in step S102 for the combination is acquired. Then, it is temporarily stored in the work area of the RAM 112 (step S106). Then, the process proceeds to step S107.

  In step S107, it is determined whether there is a combination that has not yet been processed among the combinations registered in the gaming state table. If there is a combination that has not yet been processed, the process returns to step S103, and the process is continued with the processing target as the next combination. If there is no combination not to be processed, each combination registered in the game state table is acquired, and a determination value to be won is assigned to each combination based on the number of determination values temporarily stored in the RAM 112, as shown in FIG. A winning determination table is generated (step S108).

  Next, the upper limit determination value is acquired as the processing target in order for the combination registered in the winning determination table generated in step S108 (step S109). The acquired upper limit determination value is compared with the value of the random number for internal lottery acquired in the random number acquisition process in step S101 (step S110). As a result of the comparison, it is determined whether the value of the random number for internal lottery is less than or equal to the upper limit determination value (step S111).

  If it is below the upper limit determination value, it is determined whether the combination to be processed is a big bonus, a regular bonus, or RT (step S112). If it is any of the above, whether or not the big bonus winning flag, the regular bonus winning flag, or the RT winning flag (which may be different from the role being dealt with) is already set in the RAM 112 in the game before the previous time. Determination is made (step S113). If the big bonus winning flag, the regular bonus winning flag, or the RT winning flag is set, the lottery process is terminated as it is, and the process returns to the flowchart of FIG.

  If the combination to be processed in step S112 is neither a big bonus, a regular bonus, nor RT, or if none of the big bonus winning flag, regular bonus winning flag, or RT winning flag is set in step S113 The winning flag of the target combination is set in the RAM 112 (step S114). Then, the lottery process is terminated, and the process returns to the flowchart of FIG.

  If it is determined in step S111 that the value of the random number for internal lottery is greater than the upper limit determination value, whether there is a combination that has not yet been processed among the combinations registered in the winning determination table. Is determined (step S115). If there is a combination that has not yet been processed, the process returns to step S109, and the processing is continued with the processing target as the next combination. If there is no combination not to be processed, the lottery process is terminated and the process returns to the flowchart of FIG.

  Of the winning flags set in the lottery process, the big bonus winning flag, the regular bonus winning flag, and the RT winning flag are erased when winning in the game, but are carried over from the next game onward. The small role winning flag, the replay winning flag, the JAC winning flag, and the JACIN winning flag are deleted at the end of the game regardless of whether or not the game is won.

  Next, the random number acquisition process in step S101 will be described in detail. FIG. 13 is a flowchart showing in detail the random number acquisition process executed by the CPU 111 in step S101. In the random number acquisition process, first, interrupt to the CPU 111 is prohibited (step S201). Next, a sampling command is output to the sampling circuit 116, the random number generated by the random number generation circuit 115 is latched, and the value of the latched random number is input from the I / O port 114 and extracted. The random number value extracted from the random number generation circuit 115 is stored in the general-purpose register 111GR (step S202).

  Next, the lower byte value and upper byte value of the random number stored in the general-purpose register 111GR are exchanged with each other using the work area of the RAM 112 (step S203). Next, the value of the random number stored in the general-purpose register 111GR is ORed with 8080h (step S204). Further, the upper byte (15th to 8th bits) is shifted downward by 1 bit, and 1 is inserted into the empty 15th bit. At this time, the value stored in the general-purpose register 111GR is acquired as a random number for internal lottery and stored in a predetermined area of the RAM 112 (step S205). Then, after permitting the interrupt prohibited in step S201 (step S206), the random number acquisition process is terminated, and the process returns to the flowchart of FIG.

  Next, the reel control distribution process in step S4 will be described in detail. FIG. 14 is a flowchart showing in detail the reel control distribution process executed by the CPU 111 in step S4. First, it is confirmed whether JAC is won or not (step S301). If JAC is won, the reel control table with table number 08 is selected (step S302), and the process returns to the flowchart of FIG.

  If JAC is not won in step S301, it is confirmed whether JACIN is won (step S303). If JACIN is won, the reel control table with table number 09 is selected (step S304), and the process returns to the flowchart of FIG.

  If JACIN is not won in step S303, it is confirmed whether or not replay is won (step S305). If the replay is won, the reel control table with the table number 04 is selected (step S306), and the process returns to the flowchart of FIG.

  If replay is not won in step S305, it is confirmed whether cherry, watermelon or bell is won (step S307). If any of cherry, watermelon or bell is won, a reel control table capable of aligning the combination of the corresponding combinations is selected from the reel control tables of table numbers 01 to 03 (step S308). Return to the flowchart.

  If none of the cherries, watermelons and bells is won in step S307, it is confirmed whether or not the regular bonus is won (step S309). If the regular bonus is won, the reel control table with table number 05 is selected (step S310), and the process returns to the flowchart of FIG.

  If the regular bonus is not won in step S309, it is confirmed whether or not the big bonus is won (step S311). If the big bonus is won, the reel control table with the table number 06 is selected (step S312), and the process returns to the flowchart of FIG.

  If the big bonus is not won in step S311, it is confirmed whether RT is won (step S313). If RT is won, the reel control table with table number 07 is selected (step S314), and the process returns to the flowchart of FIG.

  If RT is not won in step S313, whether or not the current gaming state is in the regular bonus is checked based on whether or not the regular bonus flag is set (step S315). If the regular bonus is in effect, the reel control table with table number 10 is selected (step S316), and the process returns to the flowchart of FIG.

  If the regular bonus is not in step S315, it is confirmed whether or not the current gaming state is in the big bonus depending on whether or not the big bonus flag is set (step S315). If it is during the big bonus, the reel control table with the table number 11 is selected (step S317), and the process returns to the flowchart of FIG.

  If it is not during the big bonus in step S317, that is, if it is the normal gaming state, the reel control table with the table number 12 is selected (step S319), and the process returns to the flowchart of FIG.

  As described above, in the reel control distribution process, if any combination is won in the internal lottery, a reel control table that defines a control pattern for drawing the combination of the combination is selected, and any combination in the internal lottery is selected. If not selected, a reel control table that defines a control pattern for deriving the display mode of the loss is selected.

  Next, the reel fluctuation stop process in step S6 will be described in detail. FIG. 15 is a flowchart showing in detail the reel fluctuation stop process executed by the CPU 111 in step S6. First, after the rotation of the reels 3L, 3C, and 3R reaches a constant speed, there is a predetermined condition that enables the reels 3L, 3C, and 3R to stop the reels 3L, 3C, and 3R to detect the reference position after all. It is determined whether or not it is established (step S401).

  If this predetermined condition is not satisfied, the process of step S401 is repeated, and the process waits for the predetermined condition to be satisfied. When this predetermined condition is satisfied, the reel stop timer for forcibly stopping the rotation of the reels 3L, 3C, 3R is started (step S402). Further, the left, middle, and right stop buttons 12L, 12C, and 12R are enabled to operate, and the respective operation enable lamps 63L, 63C, and 63R are turned on (step S403). Then, the process proceeds to step S404.

  In step S404, it is determined whether or not the left stop button 12L is operated based on the detection signal of the stop switch 42L. If it is determined that the left stop button 12L is not operated, the process proceeds to step S407 as it is. If it is determined that the left stop button 12L is being operated, the left stop button 12L is subsequently disabled, and the operation enable lamp 63L is turned off (step S405). Next, a reel stop control process, which will be described in detail later, is performed with the left reel 3L as the target reel (step S406). Then, the process proceeds to step S407.

  In step S407, based on the detection signal of the stop switch 42C, it is determined whether or not the middle stop button 12C is being operated. If it is determined that the middle stop button 12C is not operated, the process proceeds to step S411. If it is determined that the middle stop button 12C is being operated, the middle stop button 12C is subsequently disabled, and the operation valid lamp 63C is turned off (step S408). Next, a reel stop control process, which will be described in detail later, is performed with the middle reel 3C as the target reel (step S409). Then, the process proceeds to step S410.

  In step S410, it is determined whether the right stop button 12R is operated based on the detection signal of the stop switch 42R. If it is determined that the right stop button 12R has not been operated, the process directly proceeds to step S413. If it is determined that the right stop button 12R is being operated, the right stop button 12R is subsequently disabled, and the operation enable lamp 63R is turned off (step S411). Next, a reel stop control process, which will be described in detail later, is performed using the right reel 3R as the target reel (step S412). Then, the process proceeds to step S414.

  In step S413, it is determined whether all the left, middle and right reels 3L, 3C, 3R are stopped. When all the reels 3L, 3C, 3R are stopped, the reel fluctuation stop processing is ended and the process returns to the flowchart of FIG. On the other hand, if any one of the reels 3L, 3C, 3R has not stopped, it is determined whether or not the reel stop timer that started timing in the reel variation start process has counted a predetermined time (for example, 30 seconds). Determination is made (step S414). If the reel stop timer has not timed the predetermined time, the process returns to step S405, and the processes of steps S404 to S414 are repeated.

  When the reel stop timer counts the predetermined time, the stop mode of the reels 3L, 3C, 3R is set to the automatic stop mode (step S415). Further, a reel stop control process, which will be described in detail later, is performed to stop the rotation of the reels 3L, 3C, 3R that have not been stopped yet (step S416). Then, the reel fluctuation stop process is terminated, and the process returns to the flowchart of FIG.

  Next, the reel stop control process in steps S406, S409, S412, and S416 will be described in detail. 16 and 17 are flowcharts showing in detail the reel stop control process executed by the CPU 111 in steps S406, S409, S412, and S416. In the reel stop control process, it is first determined whether or not the stop mode of the reels 3L, 3C, 3R is set to the automatic stop mode (step S501).

  When the automatic stop mode is not set, the rotation of one of the reels 3L, 3C, 3R is stopped by operating the stop buttons 12L, 12C, 12R. It is determined whether there is a reel that has already stopped rotating (step S502). If there is no reel that has already stopped, that is, if the reels 3L, 3C, and 3R are all rotating, the player performs a stop operation with reference to the reel control table of the table number selected in the reel control distribution process in step S4. The symbol to be derived is selected on the basis of the number of drawn symbols corresponding to the timing of performing, and the rotation of the target reel is stopped (step S503). Then, the reel stop control process ends, and the process returns to the flowchart of FIG.

  If there is a reel whose rotation has already stopped among the reels 3L, 3C, 3R in step S502, the design of the symbol derived for the already stopped reel is examined (step S504). Then, referring to the reel control table of the table number selected in the reel control distribution process in step S4, the drawing state corresponding to the symbol mode derived to the stopped reel and the timing at which the player performs the stop operation A symbol to be derived is selected based on the number of symbols, and rotation of the target reel is stopped (step S505). Then, the reel stop control process ends, and the process returns to the flowchart of FIG.

  On the other hand, if it is determined in step S501 that the stop mode of the reels 3L, 3C, 3R is set to the automatic stop mode, it is first determined whether all the reels 3L, 3C, 3R are still rotating. (Step S511). If all of the reels 3L, 3C, and 3R are rotating, it is considered that the winning flag for any combination is not set in the RAM 112 (including the case where the winning flag is not originally set), and according to the stop timing. Then, the rotation of the reels 3L, 3C, 3R is stopped (step S512). Here, the reels 3L, 3C, and 3R may be stopped sequentially from the left to the right, but may be performed in another order. Then, the reel stop control process ends, and the process returns to the flowchart of FIG.

  Here, “stop according to the stop timing” means that the symbols of the winning combination are aligned based on the current symbol position when the stop condition is satisfied in each reel and the set winning flag. The reels are stopped by performing control or removing control so that the symbols of roles that have not been won (including cases where the winning flag is not set) are not aligned. (Hereafter, the same in the description of this flowchart).

  If all the reels 3L, 3C, 3R are not rotating, it is determined whether the left reel 3L has already stopped rotating (step S513). If the left reel 3L has not stopped rotating, it is determined whether or not the middle reel 3C has stopped rotating (step S514). If the middle reel 3C has stopped rotating, it is further determined whether the right reel 3R has also stopped rotating (step S515).

  If the right reel 3R has stopped rotating, it is regarded that no winning flag for any combination is set in the RAM 112, and the rotation of the left reel 3L is stopped according to the stop timing (step S516). Then, the reel stop control process ends, and the process returns to the flowchart of FIG.

  If the right reel 3R has not stopped rotating, it is considered that no winning flag of any combination is set in the RAM 112, and the rotation of the left reel 3L is stopped according to the stop timing (step S517). Further, the rotation of the right reel 3R is stopped (step S518). Then, the reel stop control process ends, and the process returns to the flowchart of FIG.

  If the rotation of the middle reel 3C has not stopped in step S514, it is a case where only the right reel 3L has already stopped, and it is assumed that the winning flag for any combination is not set in the RAM 112. The rotation of the left reel 3L is stopped according to the stop timing (step S519), and further the rotation of the middle reel 3C is stopped (step S520). Then, the reel stop control process ends, and the process returns to the flowchart of FIG.

  If the left reel 3L has stopped rotating in step S513, it is further determined whether or not the middle reel 3C has stopped rotating (step S521). If the middle reel 3C has not stopped rotating, it is further determined whether the right reel 3R has also stopped rotating (step S522). If the right reel 3R has stopped rotating, it means that only the middle reel 3C is rotating, and it is considered that no winning flag for any combination is set in the RAM 112, and the middle reel 3C is set according to the stop timing. Is stopped (step S523). Then, the reel stop control process ends, and the process returns to the flowchart of FIG.

  If the rotation of the right reel 3R is not stopped, it means that the middle reel 3C and the right reel 3R are rotating, and it is assumed that the winning flag of any combination is not set in the RAM 112, and according to the stop timing. Then, the rotation of the middle reel 3C is stopped (step S524), and the rotation of the right reel 3R is further stopped (step S525). Then, the reel stop control process ends, and the process returns to the flowchart of FIG.

  If the middle reel 3C has stopped rotating in step S521, it means that only the right reel 3R is rotating, and it is considered that no winning flag of any combination is set in the RAM 112, and the stop timing is reached. Accordingly, the rotation of the right reel 3R is stopped (step S526). Then, the reel stop control process ends, and the process returns to the flowchart of FIG.

  When the automatic stop mode is set as described above, if all of the reels 3L, 3C, and 3R are rotating, a display mode of losing is derived in the variable display device 2 regardless of the setting of the winning flag. The In addition, even if some of the reels have already stopped, when the rotation of the third stop reel is stopped (steps S516, S518, S520, S523, S525, S526), the winning flag of any combination is set. Since it is regarded as not being set, a display mode of losing is derived in the variable display device 2.

  Next, the winning determination process in step S7 will be described in detail. 18 and 19 are flowcharts showing in detail the winning determination process executed by the CPU 111 in step S7. First, it is confirmed whether or not the current gaming state is in the regular bonus depending on whether or not the regular bonus flag is set (step S601).

  If it is during the regular bonus, it is confirmed whether or not the “bell” has stopped on the active line of any reel (step S602), and the “bell” has stopped on the active line of any reel. For example, it is confirmed whether or not symbols other than “bell” have stopped on other reels on the active line where “bell” has stopped (step S603). In steps S602 and S603, the “bell” is stopped on the active line of one of the reels, and the symbols other than “bell” are stopped on the other reels on the active line where “bell” is stopped. For example, it is determined that the JAC is won, and 15 pieces are set in the RAM 112 as the payout number (step S604). Then, the winning determination process is terminated, and the process returns to the flowchart of FIG.

  If it is determined in step S601 that the regular bonus is not in progress, it is checked whether the “cherry-any-any” combination has been stopped on the active line (step S605). That is, it is confirmed whether or not “cherry” is stopped on the left reel 3L. If the combination of “cherry-any-any” is stopped on the active line, it is determined that a cherry prize has been awarded, and the number of effective lines in which the combination of “cherry-any-any” is arranged in the RAM 112 as the number of payouts. A number obtained by multiplying 2 which is the number of winning payouts is set (step S606). In the present embodiment, when “cherry” stops in the middle stage of the left reel 3L, the combination of “cherry-any-any” is aligned on one effective line that is horizontally arranged in the middle stage. When the “cherry” stops at the upper or lower stage of the left reel 3L, two effective lines lined up horizontally on the upper or lower stage and two effective lines lined on the diagonal line on the lower left or the diagonal line on the lower right Since the combination of “cherry-any-any” has been prepared on the line, four sheets are set as the number of payouts. Then, the winning determination process is terminated, and the process returns to the flowchart of FIG.

  If the “cherry-any-any” combination is not stopped on the active line in step S605, it is confirmed whether the “watermelon-watermelon-watermelon” combination is stopped on the active line (step S607). ). If the “watermelon-watermelon-watermelon” combination is stopped on the active line, it is determined that the watermelon has been won, and six pieces are set in the RAM 112 as the payout number (step S608). Then, the winning determination process is terminated, and the process returns to the flowchart of FIG.

  If the “watermelon-watermelon-watermelon” combination is not stopped on the active line in step S607, it is confirmed whether the “bell-bell-bell” combination is stopped on the active line (step S609). ). Then, if the combination of “bell-bell-bell” is stopped on the active line, it is determined that a bell is won, and eight sheets are set in the RAM 112 as the number of payouts (step S610). Then, the winning determination process is terminated, and the process returns to the flowchart of FIG.

  Further, if the combination of “bell-bell-bell” is not stopped on the active line in step S609, it is confirmed whether or not the current gaming state is in the big bonus depending on whether or not the big bonus medium flag is set (step S609). S611). If it is during the big bonus, it is checked whether or not “Plum” has stopped on the active line of any reel (step S612), and “Plum” has stopped on the active line of any reel. If so, it is checked whether symbols other than “Plum” have stopped on the other reels on the active line where “Plum” has stopped (Step S613). Then, in steps S612 and 613, “Plum” has stopped on the active line of one of the reels, and symbols other than “Plum” have stopped on the active line where “Plum” has stopped. For example, it is determined that the JACIN winning is determined, and a regular bonus flag is set in the RAM 112 (step S614). Then, the winning determination process is terminated, and the process returns to the flowchart of FIG.

  If it is not during the big bonus in step S611, it is confirmed whether or not the “plum-plum-plum” combination is stopped on the active line (step S615). Then, if the combination of “plum-plum-plum” is stopped on the active line, it is determined that a replay prize has been won, and a replay game flag is set in the RAM 112 (step S616). Then, the winning determination process is terminated, and the process returns to the flowchart of FIG.

  If the “Plum-Plum-Plum” combination is not stopped on the effective line in Step S615, it is confirmed whether the “BAR-BAR-BAR” combination is stopped on the effective line (Step S617). ). If the “BAR-BAR-BAR” combination is stopped on the active line, it is determined that the regular bonus is won, the regular bonus winning flag set in the RAM 112 is cleared (step S618), and the RAM 112 is stored. A regular bonus medium flag is set (step S619). Then, the winning determination process is terminated, and the process returns to the flowchart of FIG.

  If the combination “BAR-BAR-BAR” is not stopped on the active line in step S617, it is confirmed whether the combination “7-7-7” is stopped on the active line (step S620). ). If the combination of “7-7-7” is stopped on the active line, it is determined that the big bonus is won, the big bonus winning flag set in the RAM 112 is cleared (step S621), and the RAM 112 is stored. A big bonus medium flag is set (step S622). Then, the winning determination process is terminated, and the process returns to the flowchart of FIG.

  If the combination “7-7-7” is not stopped on the active line in step S620, it is confirmed whether the combination “7-7-BAR” is stopped on the active line (step S620). S623). If the combination of “7-7-BAR” is stopped on the active line, it is determined that the RT winning is determined, the RT winning flag set in the RAM 112 is cleared (step S624), and the RAM 112 is in the RT state. A flag is set (step S625). Then, the winning determination process is terminated, and the process returns to the flowchart of FIG.

  If the combination of “7-7-BAR” is not stopped on the active line in step S623, the winning determination process is terminated and the process returns to the flowchart of FIG.

  As described above, in the winning determination process in step S6, the type of winning is determined based on the combination of symbols stopped on the active line.

  In particular, during the regular bonus, “bell” stops on the active line of any reel, and symbols other than “bell” stop on the active line where “bell” stops. If so, it is determined that the JAC prize has been won. In other words, during the regular bonus, if the “bell” stops on the active line of any reel and the combination of “bell-bell-bell” is not on the active line, it is determined that the JAC is awarded. Become. On the other hand, in the small game in the normal gaming state and the big bonus, the “bell” is stopped on the active line of one of the reels, and the other reels “ Even if the symbols other than “bell” are stopped, it is not determined that the winning is achieved, but if the combination of “bell-bell-bell” is aligned on the active line, it is determined that the winning is the bell.

  In addition, in the small bonus game during the big bonus, “Plum” stops on the active line of any reel, and symbols other than “Plum” appear on the other reels on the active line where “Plum” stops. If it is stopped, it is determined that JACIN is won. In the present embodiment, the winning combination of the small role is determined, and when the winning of the small role is not determined, the JACIN winning determination is performed, so that there is no combination of small roles on the effective line. If “Plum” is stopped on the effective line of any reel and the combination of “Plum-Plum-Plum” is not on the effective line as a condition, it is determined that the JACIN winning is achieved. On the other hand, in the normal gaming state, “Plum” stops on the active line of any reel, and symbols other than “Plum” stop on the active line where “Plum” stops. However, if a combination of “Plum-Plum-Plum” is aligned on the active line, it will be determined that the player has won a replay.

  In this embodiment, the winning of the small role is determined, and if the winning of the small role is not determined, the JACIN winning determination is performed. However, the winning of the small role is prioritized. JACIN winning determination may be performed, and JACIN winning determination may be performed regardless of whether or not combinations of small roles are aligned on the active line.

  As described above, in the slot machine 1 according to the present embodiment, the number of determination values that determines the winning probability of each combination determined according to the gaming state is stored at an address referenced from the gaming state table. The storage address may differ depending on the set value and / or the number of bets, but for the role that makes the winning probability the same regardless of the set value and / or the number of bets, it is stored. The previous address is shared, that is, the determination value number is stored in common regardless of the set value and / or the bet number. By storing the number of determination values in common in this way, the storage capacity required for that is reduced. That is, the amount of data for performing the internal lottery can be suppressed.

  In the internal lottery, for each combination registered in the gaming state table corresponding to the gaming state in the game, the number of determination values is acquired according to the set value and the number of bets in the game. It is assumed that a winning determination table to be applied is generated. Then, the determination value registered in the generated winning determination table is compared with a random number for internal lottery to perform internal lottery.

  By the way, as shown in FIG. 6, there is an address that stores the number of determination values referred to according to the number of bets for the same combination from the table according to the game state of the same game state, such as a watermelon in the normal game state or RT. Even if they are different, if the number of judgment values stored at different addresses is the same, or according to the setting value for the same combination from the table according to the game state of the same game state, such as a cherry in the normal game state or RT Even if the addresses storing the number of judgment values to be referred to are different, the number of judgment values stored at different addresses may be the same. In other words, even if the number of determination values is separately registered for the same combination according to the set value and / or the number of bets, the number of determination values may be the same.

  In general, at the development stage, it is assumed that the simulation is performed while adjusting the number of judgment values according to the set value and / or the number of bets (that is, adjusting the winning probability of internal lottery) for at least some of the roles Yes. As the initial number of decision values, a different number of decision values was registered according to the set value and / or bet number, but as a result of adjustment by simulation, the decision when the set value and / or bet number is different The number of values may be the same. As the initial number of judgment values, the same number of judgment values was registered according to the set value and / or the number of bets. However, the number of judgment values registered from the beginning may be used as it is based on the simulation results. There is a case where the number of determination values is different from the original, that is, the number of determination values is different depending on the set value and / or the number of bets, depending on the result of simulation. Then, the number of determination values obtained with an appropriate result in the simulation in each case is selected as the number of determination values to be set for the mass production model.

  Here, even if the number of determination values adjusted by the simulation becomes the same regardless of the set value and / or the number of bets, the number of determination values is assigned to the ROM 113 by the same address assignment as the address assignment in the development stage. And can be used as a model for mass production. For this reason, it is not necessary to change the method for storing the number of judgment values from the development model in the mass production model, and the development from the initial design stage to the transition to the mass production model can be easily performed. Become.

  The random number for internal lottery acquired by the random number acquisition process is not used as it is from the random number generation circuit 115 by the sampling circuit 116 but is used after being processed by software. The random number generation circuit 115 generates a random number by updating at a high speed with the frequency of the pulse signal of the pulse generation circuit 115a. However, in the random number for internal lottery processed by software, the periodicity of the update is increased by the processing. It will be lost.

  On the other hand, since it is not good in terms of processing efficiency to vary the judgment value for each winning combination from the judgment value number read from the address registered in the gaming state table according to the set value and the number of bets, As shown in FIG. 5, it is assumed that the determination value for determining each combination registered in the winning determination table as winning is a solid value. However, the randomness for the internal lottery to be compared with the determination value registered in the winning determination table is lost in periodicity, and it is possible to prevent hitting by the player as much as possible. .

  Moreover, the frequency of the pulse signal generated by the pulse generation circuit 115a to update the values of the counters 115b and 115c of the random number generation circuit 115 is higher than the frequency of the operation clock of the CPU 111, and is not an integral multiple. For this reason, the update of the random number generated by the random number generation circuit 115 becomes difficult to synchronize with the processing performed by the CPU 111. In addition, by increasing the frequency of the pulse signal of the pulse generation circuit 115a, the update speed of the random number generated by the random number generation circuit 115 can be made extremely fast.

  On the other hand, the processing of random numbers by software is performed by replacing the upper byte and lower byte of the random number extracted from the random number generation circuit 115 by the sampling circuit 116, masking the 15th and 7th bits, and then bit-shifting the upper byte. good. Therefore, even for a relatively large random number of 16 bits (actually masked 14 bits), the load required for processing necessary to lose periodicity is not so large, and can be easily obtained. Can do. Since a large random number can be acquired in this way, the probability setting in the internal lottery can be finely performed.

  Further, in the slot machine 1 in the present embodiment, in the small game in the normal gaming state and the big bonus, if the combination of “bell-bell-bell” is aligned on the active line, it is determined that the bell is won. During the regular bonus, “bell” stops on the active line of any reel, and symbols other than “bell” stop on the active line where “bell” stops. In this case, it is determined that a JAC prize has been won. On the other hand, in the normal gaming state, if the combination of “plum-plum-plum” is aligned on the active line, it is determined that a replay is won, whereas in a small role game with a big bonus, If “Plum” is stopped on the active line and a symbol other than “Plum” is stopped on the other reels on the active line where “Plum” has stopped, it is determined that the JACIN winning. For this reason, even when multiple types of winnings such as Bell winning and JAC winning or Replay winning and JACIN winning are generated using common symbols such as “Bell” and “Plum” in different gaming states, This makes it easier to understand the difference between the types of prizes.

  Furthermore, a JAC prize is determined if “bell” stops on the active line of any reel, and symbols other than “bell” stop on other reels on the active line where “bell” stops. Is selected in the internal lottery, the reel control table with table number 08 is selected, and control is performed to stop the “bell” on the active line except for one of the reels. Can be easily understood on the active line. Similarly, if “Plum” is stopped on the active line of any reel, and symbols other than “Plum” are stopped on other effective reels on the active line where “Plum” has stopped. When the JACIN winning is won by internal lottery, the reel control table with table number 09 is selected, and control is performed to stop “Plum” on the active line except for any one reel. It can be easily understood that the winning combinations are aligned on the active line.

  In this embodiment, “bell” and “plum” are arranged so as to be within the pull-in range in all the reels 3L, 3C, 3R. The “bell” always stops on the active line on the reels, the symbols other than “bell” always stop on the active line on the remaining reels, and if JACIN is elected, it is effective on any two reels. “Plum” always stops on the line, and symbols other than “Plum” always stop on the active line in the remaining reels. For example, these specific symbols have a pull-in range. If it is located beyond the limit, it is only when the stop timing comes when the specific symbol is located in the pull-in range, that is, as long as possible the effective labels on any two reels. The specific symbols stopped on emissions, may be stopped symbols other than the specific symbol on the effective line on the rest of the reel.

  In this embodiment, when JAC is won, the “bell” is stopped on the same effective line in the first stop reel and the second stop reel, and “ Controls to stop symbols other than “bell” are performed, and “bell” is derived on the same active line except for the reel from which the display result is finally derived. Therefore, the symbols constituting the JAC winning Can be more easily understood.

  Further, in this embodiment, when JACIN is elected, “plum” is stopped on the same effective line as much as possible in the first stop reel and the second stop reel, and the first stop reel and the second stop reel are stopped. When “Plum” stops on the same effective line in the reel, control is performed to stop symbols other than “Plum” on the effective line in the third stop reel, and the same in the first stop reel and the second stop reel. When the “plum” does not stop on the active line, the third stop reel performs control to stop the “plum” on the active line where the “plum” of the first stop or the second stop reel has stopped. “Plum” is derived as much as possible on the same active line except for the reel from which the display result is finally derived. Even if the “plum” does not stop on the same effective line in the reel and the second stop reel, the “plum” on the effective line where the “plum” of the first stop or the second stop reel stops in the third stop reel. Therefore, the combination of symbols constituting the JACIN winning can be more easily understood.

  In this embodiment, when JACIN is elected, the “plum” is stopped on the same effective line as much as possible in the first stop reel and the second stop reel, and the first stop reel and the second stop reel. When the “plum” stops on the same effective line in the reel, control is performed to stop symbols other than “plum” on the effective line in the third stop reel. The second stop reel may be controlled to stop symbols other than “plum”, and the third stop reel may be controlled to stop the “plum” symbol as much as possible on any active line. If you do this, you won't know if you will win the JACIN until you stop the last reel. Lumpur can be sustained until it stops. Further, in this case, a reel having the “plum” arranged beyond the pulling range may be provided, and in this way, for example, a reel other than the reel having the “plum” arranged beyond the pulling range may be provided. When stopping the last reel as the first stop and the second stop reel, the stop operation is performed at a timing that is within the “plum” pull-in range, or the stop operation is performed at a timing that is outside the “plum” pull-in range The player can select whether or not to generate a JACIN prize. As a result, an act of increasing the number of acquired medals without intentionally generating a JACIN winning, that is, a so-called replay scratch is possible.

  Also, in this embodiment, during the regular bonus that shifts when an RB win is made in the normal gaming state or when a JACIN win is made in a small bonus game during a big bonus, When “Bell” stops and a symbol other than “Bell” stops on another reel on the active line where “Bell” stops, it is determined that a JAC prize has been won. When a combination of “bell-bell” is prepared, it is determined that a bell is won, and when a common symbol is derived on the active line in all the reels 3L, 3C, 3R in the normal gaming state. The winning combination will be judged, so the combination of symbols in the normal gaming state where the ratio of staying is high compared to the regular bonus will be easier to understand Kill.

  Also, in this embodiment, in the small bonus game during the big bonus that shifts when a BB win is made in the normal gaming state, “Plum” stops on the active line of any reel, and “Plum” When a symbol other than “Plum” stops on another active line on the stopped active line, it is determined that JACIN wins, and when a combination of “Plum-Plum-Plum” is aligned on the active line in the normal gaming state In the normal gaming state, the winning is determined when a common symbol is derived on the active line in all the reels 3L, 3C, 3R. The combination of symbols in the normal gaming state where the staying rate is high compared to the small role game can be made easier to understand.

  Furthermore, the symbols that make up the symbol combinations that will be replayed in the normal gaming state and the symbols that make up part of the symbol combinations that will become JACIN winnings that will trigger the transition to RB in the small bonus game during the big bonus are shared. Therefore, these winnings are similar to conventional slot machines, that is, replay winnings in the normal gaming state and slot machines to which a common symbol combination is applied as JACIN winnings that trigger the transition to RB during the big bonus. The difference between the types of can be clarified.

  In this embodiment, during the regular bonus, “bell” stops on the active line of any reel, and symbols other than “bell” appear on other reels on the active line where “bell” stops. When it stops, it is determined to be a JAC prize. In other words, the “bell” is applied as the constituent pattern of the target JAC winning in the regular bonus, but the “plum” common to the symbols constituting the replay winning in the normal gaming state is applied as the constituent pattern of the JAC winning, When "Plum" stops on the active line of any reel and symbols other than "Plum" stop on other reels on the active line where "Plum" stops By doing so, in a form approximate to a conventional slot machine, that is, a slot machine to which a common symbol combination is applied as a target JAC prize in a replay prize and a regular bonus in a normal gaming state, and You can easily understand the difference between these types of winnings.

  However, as described above, when “Plum” is applied to the configuration pattern of the JACIN winning, the difference between the JAC winning and the JACIN winning cannot be clarified. For this reason, for example, when one of the JAC prize and the JACIN prize is combined with the combination of “Plum-any-other (2)”, that is, “Plum” stops on the effective line of the left reel and the right reel Judgment is made when a symbol other than “plum” stops on the active line where “plum” of the left reel stops, and the other is determined when the combination of “other (2) -any-plum” is aligned, that is, right This determination is made when “plum” stops on the effective line of the reel, and in the left reel, symbols other than “plum” stop on the effective line where the “plum” of the right reel stops. In other words, the JAC winning and the JACIN winning may be distinguished and determined according to the reel where the “plum” is stopped on the active line. In this way, the JAC winning is in a form similar to the conventional slot machine. And JACIN winning types can be easily understood.

  In the slot machine 1 according to the present embodiment, if the player operates the stop buttons 12L, 12C, and 12R before the reel stop timer counts a predetermined time and is set to the automatic stop mode, the setting state of the winning flag is set. The symbol to be stopped is selected according to the timing of the stop operation and the display result is derived to the variable display device 2. In other words, winning is generated not only by setting the winning flag but also by the player's technical intervention such as operation of the stop buttons 12L, 12C, and 12R. Therefore, it is possible to prevent the winning from being generated only by chance factors. Security of sex will be secured.

  On the other hand, if the reel stop timer times out the predetermined time without the stop buttons 12L, 12C, 12R being operated by the player, the automatic stop mode is set and the rotation of the reels 3L, 3C, 3R is stopped. That is, the time required for one game is not infinite, and even if the player is playing a game, a substantially sufficient operation rate cannot be obtained.

  Also, when the rotation of the reels 3L, 3C, 3R is stopped in the automatic stop mode, the display result of the variable display device 2 is always lost regardless of which winning flag is set. The display mode is derived. For this reason, it is possible to prevent the winning display mode from being derived only by the contingency element, and to ensure the suppression of shooting characteristics. In addition, when the player stops even a part of the reels 3L, 3C, 3R without operating any part of the stop buttons 12L, 12C, 12R, and a part of the reels 3L, 3C, 3R is stopped by the automatic stop mode, a display mode of losing is always derived. . In other words, since a part of the reels 3L, 3C, 3R does not derive the winning display mode only by the chance factor that the time has passed without the stop buttons 12L, 12C, 12R being operated, it is more effective. It is possible to ensure the suppression of the shooting characteristics.

  In this embodiment, when the player does not operate any part of the stop buttons 12L, 12C, and 12R and stops even a part of the reels 3L, 3C, and 3R by the automatic stop mode, the display mode of the losing always occurs. However, if the player operates even a part of the stop buttons 12L, 12C, 12R with the winning flag set, the winning display mode corresponding to the winning flag is derived. Even in this case, at least a part of the technical intervention by the player is performed, and the winning display mode is not derived only by the contingency element that time has passed. Security of sex can be secured.

  By the way, since the left reel 3L is won with a single symbol of “cherry”, when the left reel 3L becomes the third stop reel, the symbol displayed until the second stop reel is stopped. Depending on the mode of (i.e., when the prohibition is derived), there is a case where the occurrence of winning is unavoidable. Here, when the left reel 3L becomes the third stop reel, derivation of the prohibition is avoided when the second stop reel is stopped, so that a winning occurs in the automatic stop mode or the winning flag is set. It is possible to avoid the occurrence of a winning combination that is not set. Moreover, even when the second stop reel is stopped by the operation of the stop button, control is always performed so as to avoid the derivation of the forbidden eyes at the time of the stop regardless of whether or not the winning flag is set. Therefore, even when only the third stop reel is to be stopped in the automatic stop mode, it is possible to reliably avoid the occurrence of winning. In addition, when stopping the second stop reel, that is, the reel that stops one before the reel that finally stops, the forbidden eyes are prevented from appearing, so the stage before that, that is, the first stop By avoiding the forbidden eyes from the reels, it is possible to prevent the display style of the first stop reel from being biased and the interest from deteriorating.

  The present invention is not limited to the above-described embodiments, and various modifications and applications are possible. Hereinafter, modifications of the above-described embodiment that can be applied to the present invention will be described.

  In the above embodiment, one symbol combination (for example, “BAR-BAR-BAR” for the regular bonus, “7-7-7” for the big bonus, “7-” for the RT, 7-BAR ”), for example,“ Red 7 ”and“ White 7 ”are provided in the“ 7 ”symbol, and“ Red 7-Red 7-Red 7 ”and“ A plurality of types of symbol combinations may be applied to one type of bonus, such as applying both “white 7-white 7-white 7”. Also, in this case, both “Red 7-Red 7-Red 7” and “White 7-White 7-White 7” are aligned based on the setting of one type of winning flag that allows a big bonus. The winning flag of “red 7-red 7-red 7” or “white 7-white 7-white 7” can be selected based on the winning flag corresponding to each symbol combination being set. One symbol combination corresponding to may be arranged. Then, if the big bonus winning flag is set, one of “red 7-red 7-red 7” or “white 7-white 7-white 7” is selected according to the player's preference. It becomes possible to arrange the symbol combinations. Also, if the latter is used, even if the reels are stopped aiming at one symbol combination and the combination is not aligned, there is a possibility that a big bonus will be left by aiming at the other symbol combination. Even in such a case, it is possible to maintain the player's expectation for the big bonus.

  In the above-described embodiment, “Bell-any-other (1)”, “Bell-other (1) -any”, “any-Bell-other (1)”, “other (1) -Bell” are combinations of JAC prizes. -Any "," any-other (1) -bell "," other (1) -any-bell "are applied, and one type of winning flag that allows JAC winning is set. The JAC winning combinations can be arranged based on the fact that the winning flag corresponding to each symbol combination of these JAC winnings is set, and “Bell-any-other (1)”. , "Bell-other (1) -any", "any-bell-other (1)", "other (1) -bell-any", "any-other (1)- Le "," other (1) -any- bell "of the, may be aligned with any one of the symbol combination corresponding to the winning flag.

  Further, in the above embodiment, as in the case of the JAC prize, the combinations of the JACIN prizes are “Plum-any-other (2)”, “Plum-other (2) -any”, “any-Plum-other (2)”. , “Other (2) -plum-any”, “any-other (2) -plum”, “other (2) -any-plum” are applied, and JACIN winning is permitted These JACIN winning combinations can be arranged based on the setting of one type of winning flag. However, based on the setting of the winning flag corresponding to each symbol combination of these JACIN winnings, -Any-other (2) "," plum-other (2) -any "," any-plum-other (2) "," o "her (2) -plum-any", "any-other (2) -plum", "other (2) -any-plum" so that any one symbol combination corresponding to the winning flag can be aligned. May be.

  In the above-described embodiment, some of the determination values that are common regardless of the set value are stored in common for all of the set values 1 to 6, but the determination value number is not related to the set value. A common thing can also be memorize | stored separately with respect to each of the setting values 1-6. In addition, if the number of determination values is common regardless of the set value, all of them can be stored in common for all of the set values 1 to 6.

  In the above embodiment, the number of determination values is stored in common for all of the setting values 1 to 6 or individually stored for each of the setting values 1 to 6. However, it is assumed that the number of determination values is not stored in common for all of the setting values 1 to 6 (the common flag for the setting value is not set). About 4-6, the number of judgment values can also be made common. The same applies to the number of determination values for the bet number. For example, the bet numbers 1 and 2 may be common and the bet number 3 may be individual.

  In the above embodiment, the game can be played by setting any one of 1, 2, and 3 bets other than the regular bonus. On the other hand, in the regular bonus, there is also a three-bet-dedicated machine in which a game is performed with one bet, but in other games, a game is always performed with three bets. In the three-wager dedicated machine, the winning determination table used for the internal lottery does not differ from the previous game only when the setting value is changed or when the gaming state is changed. Therefore, instead of acquiring the game situation for each game and generating a winning determination table, it is only for winning determination after the setting value is changed or when the game state is changed. A table may be generated.

  In the above embodiment, the determination value number storage area stores a determination value number in each case using a 2-byte area. However, in a general slot machine, the number of determination values of a combination such as a big bonus, a regular bonus, or RT cannot be set to exceed 255 in any game situation. As described above, for those that do not need to set the number of determination values exceeding 255, the number of determination values may be stored using only a 1-byte area.

  In the above-described embodiment, by obtaining the number of determination values from the table according to gaming state according to the gaming situation and generating a winning determination table, by comparing with a winning determination table that generates a random number for internal lottery , Was supposed to do an internal lottery. However, by performing the following processing, the internal lottery is performed without generating the winning determination table based on the number of determination values acquired from the gaming state table corresponding to the gaming situation. You can also.

  FIG. 20 is a flowchart showing a modification of the lottery process in step S3. Also in this modification, first, a random number for internal lottery is acquired based on the random number generated by the random number generation circuit 115 by the random number acquisition process shown in FIG. 13 (step S801). Further, the game situation (game state, bet number, set value) in the current game is acquired and stored in the work area of the RAM 112 (step S802).

  Next, the setting state of the common flag is referred to as the processing target for the combinations registered in the gaming state table corresponding to the current gaming state (step S803). As a result, it is determined whether the common flag is set for both the set value and the BET number (step S804). If the common flag is set in any case, the number of determination values stored in the address registered for the combination in the gaming state table is acquired (step S805). Then, the process proceeds to step S807.

  On the other hand, if the common flag is not set, the determination value number stored in the address registered in the table according to the gaming state corresponding to the current setting value and the betting number acquired in step S102 for the combination is acquired. (Step S806). Then, the process proceeds to step S807. In step S807, the number of determination values acquired in step S805 or S806 is added to the internal lottery random value, and the result of the addition is used as a new internal lottery random value. Here, it is determined whether or not an overflow has occurred when the number of determination values is added to the value of the random number for internal lottery (step S808).

  If an overflow occurs, it is determined whether the combination to be processed is a big bonus, a regular bonus, or RT (step S809). If it is any of the above, whether or not the big bonus winning flag, the regular bonus winning flag, or the RT winning flag (which may be different from the role being dealt with) is already set in the RAM 112 in the game before the previous time. Determination is made (step S810). If the big bonus winning flag, the regular bonus winning flag, or the RT winning flag is set, the lottery process is terminated as it is, and the process returns to the flowchart of FIG.

  If the combination to be processed in step S809 is neither a big bonus, regular bonus, nor RT, or if none of the big bonus winning flag, regular bonus winning flag, RT winning flag is set in step S810 The winning flag of the target combination is set in the RAM 112 (step S811). Then, the lottery process is terminated, and the process returns to the flowchart of FIG.

  If it is determined in step S808 that there is no overflow, it is determined whether there is a combination that has not yet been processed among the combinations registered in the gaming state table (step S812). If there is a combination that has not yet been processed, the process returns to step S803, and the processing is continued with the processing target as the next combination. If there is no combination not to be processed, the lottery process is terminated and the process returns to the flowchart of FIG.

  According to this modified example, the number of determination values of each combination registered in the gaming state table is added to the acquired random number for internal lottery, and depending on whether or not the result of the addition overflows, Whether or not a winning combination has been won can be determined. That is, there is no need to generate a winning determination table before the actual winning determination is made, and the loop process in the lottery process can be performed only once, and the processing efficiency of the entire lottery process becomes high. . In the above-described embodiment, the number of determination values is assigned from 0 to 16383. In this modification, each random number for internal lottery acquired is registered in the game state table. Since the number of winning combination judgment values is added and whether or not the winning of each winning combination is determined based on whether or not the result of the addition overflows, each judging value number is assigned from 16383 toward 0 Will be. However, since the number of determination values itself is the same, the winning probabilities of the respective combinations are also the same.

  In step S807, the acquired determination value number is added to the internal lottery random value. However, the acquired determination value number is subtracted from the acquired internal lottery random number value, and the result of the subtraction is newly added. It may be a random value for internal lottery. When subtracting the number of determination values from the random value for internal lottery, the 15th and 14th bits of the random number for internal lottery are set to “0” to determine whether or not an overflow has occurred in the result of the subtraction. can do.

  In the above embodiment, regardless of whether the big bonus winning flag, the regular bonus winning flag or the RT winning flag is set, when the gaming state is normal or RT, the big bonus and regular bonus (and RT (normal game) 10 is used to generate the winning determination table in which the determination values of the big bonus and the regular bonus (and RT (when in the normal gaming state) are set). The winning combination is determined to determine whether or not these roles have been won, but if the big bonus winning flag, regular bonus winning flag or RT winning flag is set, it is determined that these roles have been won. However, the corresponding winning flag is not set.

  On the other hand, when the big bonus winning flag, the regular bonus winning flag or the RT winning flag is already set, the lottery of these combinations may not be performed. That is, when the big bonus winning flag, the regular bonus winning flag or the RT winning flag is set, a winning determination table in which the determination values of these combinations are not registered or corresponding to these combinations is generated. The number of determination values may not be added to the internal lottery random number. In this case, it is possible to reduce the number of times that the size determination between the random number for internal lottery and the determination value and the overflow determination as a result of adding the number of determination values to the random number for internal lottery are performed.

  In the above embodiment, different game state tables are used for the normal game state and RT. However, only the replay and the RT (which is a role only in the normal gaming state) have different judgment value numbers applied in the normal gaming state and the RT. Therefore, the common gaming state table is shared between the normal gaming state and the RT, and the common flag similar to the common flag indicating that the determination value number is stored in accordance with the set value and the betting number for the replay and RT. Can be used to apply different numbers of decision values.

  In the above embodiment, the entire high-order byte of the random number extracted from the random number generation circuit 115 is replaced with the low-order byte, and the whole low-order byte is replaced with the high-order byte. On the other hand, the data of a specific bit among the random number bits extracted from the random number generation circuit 115 is simply replaced with data of other bits (however, other than the masked seventh and fifteenth bits). Also good. The random number value extracted from the random number generation circuit 115 may be directly compared with the winning determination table as a random number for internal lottery. In the modified example of FIG. 20, the number of determination values can be sequentially added to the random number value extracted from the random number generation circuit 115. Further, it may be processed into a random number for internal lottery by a method different from the above embodiment.

  FIG. 21 is an explanatory diagram of a first modification of the process (step S101) until the CPU 111 processes the random number extracted from the random number generation circuit 115 into a random number for internal lottery by software. Also in the first modification, the random number extracted from the random number generation circuit 115 is stored in the 16-bit general-purpose register 111GR included in the CPU 111.

  When the random number extracted from the random number generation circuit 115 is stored in the general-purpose register 111GR, the CPU 111 further extracts the value of the internal refresh register 111R as a processing random number. The CPU 111 adds the processing random number extracted from the refresh register 111R to the value of the upper byte of the general-purpose register 111GR (the value extracted from the upper counter 115c). The lower byte value of the general register 111GR (the value extracted from the lower counter 115b) is left as it is.

  Next, the CPU 111 performs a logical OR operation with the value of the general-purpose register 111GR, that is, a value obtained by adding a processing random number to the upper byte with 8080h. Further, the CPU 111 shifts the upper 1 byte (8th bit to 15th bit) to the lower bit by bit, and inserts 1 into the empty 15th bit. The CPU 111 acquires the value stored in the general-purpose register 111GR at this time as a random number for internal lottery and compares it with the determination value registered in the winning determination table.

  FIG. 22 is an explanatory diagram of a second modification of the process (step S101) until the CPU 111 processes the random number extracted from the random number generation circuit 115 into a random number for internal lottery by software. Also in this example, the random number extracted from the random number generation circuit 115 is stored in the 16-bit general-purpose register 111GR included in the CPU 111.

  When the random number extracted from the random number generation circuit 115 is stored in the general-purpose register 111GR, the CPU 111 further extracts the value of the internal refresh register 111R as a processing random number. The CPU 111 adds the processing random number extracted from the refresh register 111R to the value of the upper byte of the general-purpose register 111GR (the value extracted from the upper counter 115c). The processing random number extracted from the refresh register 111R is also added to the lower byte value (the value extracted from the lower counter 115b) of the general-purpose register 111GR.

  Next, the CPU 111 performs a logical OR operation on the value of the general-purpose register 111GR, that is, a value obtained by adding a processing random number to the upper byte and the lower byte, respectively, with 8080h. Further, the CPU 111 shifts the upper 1 byte (8th bit to 15th bit) to the lower bit by bit, and inserts 1 into the empty 15th bit. The CPU 111 acquires the value stored in the general-purpose register 111GR at this time as a random number for internal lottery and compares it with the determination value registered in the winning determination table.

  In the first and second modified examples described above, the value of the refresh register 111R is extracted as a random number for processing, and this is extracted from the high-order byte of the random number extracted from the random number generation circuit 115 (in the second modified example, further lower byte) ) To process random numbers. The random number processing applied here includes at least processing for adding a processing random number to the upper byte. Thereby, the variation of the random numbers for internal lottery can be increased, and the player can prevent the aiming as much as possible.

  Further, since the processing random numbers are extracted from the refresh register 111R, no special configuration is required as means for generating the processing random numbers. Moreover, since the value of the refresh register 111R is updated every time the CPU 111 fetches an instruction, and the update interval is not constant, a random number with high randomness can be extracted as a processing random number. And since the randomness of the processing random number is high, the randomness of the random number for internal lottery generated using the random number is also high.

  In the first and second modifications, the value extracted from the refresh register 111R is added to the upper byte (and the lower byte) of the random number extracted from the random number generation circuit 115. A value that is periodically updated by hardware or software may be added. Further, instead of adding a value extracted from the refresh register 111R (or a value replacing the refresh register 111R), a logical operation such as subtraction, logical sum, or logical product may be performed.

  Further, bit replacement such as replacement of the upper byte and the lower byte shown in the above embodiment may be used in combination with the first and second modifications. Also in the first and second modified examples, during the period from the extraction of the random number from the random number generation circuit 115 to the end of processing, the interrupt to the CPU 111 is prevented in order to prevent the contents of the general-purpose register 111GR from being rewritten. It will be prohibited.

  In the second modification, processing random numbers to be added to the upper and lower bytes of the random number extracted from the random number generation circuit 115 may be separately extracted from the refresh register 111R at different timings. Separately prepare the processing random number to be added to the upper byte and the processing random number to be updated to the lower byte. Means for extracting may be provided. In this case, one of the means for updating the processing random number for the upper byte and the means for updating the processing random number for the lower byte can be configured by the refresh register 111R.

  In the above embodiment, the case where the present invention is applied to the case where the random number generated by the random number generation circuit 115, that is, the random number extracted by the hardware random number function, is processed by software has been described. However, the random number processing by the software described above may be applied to random numbers that are periodically updated by software. For example, the microcomputer constituting the control unit 110 is an I / O port that causes the CPU 111 to send an instruction to the second microcomputer to extract a random number periodically updated by a timer interrupt or the like in the first microcomputer. It can be input to the CPU 111 via 114 and stored in the general-purpose register 111GR. The function of the second microcomputer may be included in the microcomputer constituting the control unit 110. Also in this case, the random number value obtained after processing can be varied, and the effect of preventing the player from aiming can be achieved.

  In the above-described embodiment, only the left reel 3L is awarded with a single symbol “cherry”, and therefore, a forbidden eye is generated only when the left reel 3L is the third stop reel. When the rotation of the reels 3L, 3C, 3R is stopped in the automatic stop mode, the left reel 3L is the third stop reel only when the middle and right reels 3C, 3R are already stopped (the forbidden eyes are avoided). Therefore, there has been no case where it is unavoidable to derive the winning display mode.

  On the other hand, if only the right reel 3R is awarded with a single symbol “cherry”, even if the right reel 3R is the third stop reel, a forbidden eye may occur. When stopping the rotation of the reels 3L, 3C, and 3R in the automatic stop mode, if the stop order of the reels 3L, 3C, and 3R in the automatic stop mode is the same as described above, the right reel 3R becomes the third stop reel. There is a case.

  For example, when the symbols constituting a part of the prohibition eye are derived for the left reel 3L and stopped, and the middle and right reels 3C and 3R are stopped in the automatic stop mode as the second and third stop reels, Instead of the middle reel 3C as the second stop reel, the right reel 3R is selected as the second stop reel, and the right reel 3R and the middle reel 3C may be stopped according to the selected order. If the symbols constituting a part of the prohibition eye are not derived for the left reel 3L, the middle reel can be selected as the second stop reel and can be stopped in the order of the middle reel 3C and the right reel 3R according to the selected order. .

  Even when the symbols constituting a part of the forbidden eye are derived and stopped for the left reel 3L, the middle reel 3C is always used when the middle and right reels 3L, 3C are stopped in the automatic stop mode. It is assumed that the right reel 3R is stopped in the order, but when stopping the middle reel 3C as the second stop reel, it is determined whether or not a symbol constituting a part of the prohibited eye is derived for the left reel 3L. If a symbol for deriving a part of the forbidden eye is derived, a symbol that does not constitute the forbidden eye is selected from the symbols that can be selected as the stop symbol for the middle reel 3C and stopped. can do.

  In any case, no prohibition is drawn to the variable display device 2 when the second stop reel is stopped, so that a prize is awarded when the rotation of the reels 3L, 3C, 3R is stopped in the automatic stop mode. It can be avoided that the display mode is derived.

  In the above embodiment, when a part of the reels 3L, 3C, 3R is stopped in the automatic stop mode, the stop symbol is selected within the range of the maximum delay time of 190 milliseconds. You may enable it to select a stop symbol, without receiving a restriction | limiting. If the stop symbol can be selected without being limited by the maximum delay time, no prohibition will occur in the symbol arrangement of FIG. 2, so that the prohibition will be derived when the second stop reel is stopped. The control to avoid becomes unnecessary.

  In the above embodiment, when the stop condition is satisfied by operating the stop buttons 12L, 12C, and 12R, the stop position of the symbol is determined with reference to the reel control table in which the stop position is determined in advance. While the reels 3L, 3C, and 3R stop rotating with the table system that stops the reel at the stop position, the stop condition is satisfied when the stop condition is satisfied because the reel stop timer times a predetermined time. As an example, a slot machine that stops the rotation of the reels 3L, 3C, and 3R by a control method that performs pull-in control or removal control based on the current symbol position at the time, that is, a slot machine that uses both the table method and the control method has been described. . On the other hand, regardless of whether the stop condition is satisfied by operating the stop buttons 12L, 12C, and 12R or whether the stop condition is satisfied by the reel stop timer measuring a predetermined time, the stop condition is When the above is established, the present invention can also be applied to a slot machine that stops the rotation of the reels 3L, 3C, and 3R only by the table method, and a slot machine that stops the rotation of the reels 3L, 3C, and 3R only by the control method.

  In the former case, when all of the reels 3L, 3C, 3R are set to the automatic stop mode without stopping, the stop position of the symbol is determined by referring to the table in which the control for deriving the display mode of the loss is registered. good. When a part of the reels 3L, 3C, 3R is set to the automatic stop mode without stopping, refer to the table corresponding to the winning corresponding to the winning flag considered not set above. Then, the stop position of the symbol may be determined. In the latter case, when the stop button 12L, 12C, 12R is operated and the stop condition is satisfied, the pull-in control or the release control is performed based on the current symbol position, but the setting state of the winning flag is the same. Even in this case, it is sufficient to perform control such as drawing different symbols in accordance with the type of reel control selected in the reel control distribution process.

  In the above embodiment, the reel stop timer sets the automatic stop mode when the predetermined time has elapsed, forcibly stops the rotation of the reels 3L, 3C, and 3R. Regardless of whether the flag is set or not, the display mode of losing that is not the winning display mode of any role is always derived, and it is possible to prevent the occurrence of winning by only the chance factor, The rotation of the reels 3L, 3C, and 3R is stopped only when the player operates the stop buttons 12L, 12C, and 12R without forcibly stopping the rotation of the reels 3L, 3C, and 3R. Well, according to this, regardless of the time that the stop buttons 12L, 12C, 12R have not been operated by the player, the stop button 12 by the player. Until the 12C and 12R are operated, the variation of the symbols in the variable display device 2 continues, and the display result is not derived. Therefore, the player does not operate the stop buttons 12L, 12C and 12R, and the time is not increased. The winning display mode is not derived only by the contingency element that has passed, and it is possible to ensure the suppression of shooting characteristics.

  Also, in this case, in a game in which no winning combination is won, the reel stop timer sets the automatic stop mode by counting the predetermined time, and the rotation of the reels 3L, 3C, 3R is forcibly stopped. You may make it let it. According to this, in a game in which no winning combination is won, that is, a game with no room for technical intervention, the reel stop timer is set for a predetermined time even if the stop buttons 12L, 12C, 12R are not operated by the player. If the time is counted, the display result is derived to the variable display device 2 and one game is completed. Therefore, the time required for one game can be limited, and a substantial reduction in the operating rate of the slot machine can be prevented. it can.

  In the above embodiment, the variable display device 2 includes the three reels 3L, 3C, and 3R in which a plurality of symbols are arranged in a predetermined order on the outer periphery, and the symbols are displayed by rotating the reels 3L, 3C, and 3R. It was supposed to be variably displayed.
