Description

  The present invention relates to a slot machine, and more particularly, to a slot machine having a plurality of types of allowable stages (so-called setting values) having different ratios for determining that a winning display result is allowed to be derived.

  A slot machine generally includes a variable display device having a plurality of (usually three) reels having a plurality of types of symbols as identification information drawn on the outer periphery, and each reel has a start lever by a player. Rotation is started by operating, and when the player operates a stop button provided corresponding to each reel, the rotation is stopped within a range of a predetermined maximum delay time from the operation timing. . Then, a prize is generated according to the display mode derived when the rotation of all the reels is stopped.

  In order for a winning of each combination determined for each slot machine to occur, generally, a winning flag must be set by winning an internal lottery performed in advance (usually when the start lever is operated). . In the internal lottery, a random number for internal lottery that is regularly updated by hardware or software is extracted, and the value of the extracted random number is stored in a winning determination table prepared according to the set value, the number of bets, and the gaming state. By comparing, it is determined whether or not each combination determined according to the gaming state has been won.

Here, the winning probability of each combination in the internal lottery can be changed according to the set value so that the payout rate of medals in each slot machine can be varied in the game store. Data for proceeding with a game in such a slot machine is stored in the RAM of the main control unit that controls the game, and the required data among the data stored in the RAM according to the game situation There is a thing that clears (see, for example, Patent Document 1).

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 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 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 configuration of the RAM 112 will be described later.

  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. Note that information (commands) is sent from the game control board 101 to the effect control board 102 only in one direction, and no information (commands) is sent 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.

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 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 92 after the setting key switch 92 is turned on. When the power is turned on without setting key switch 92 turned on, if the data in RAM 112 is normal, it returns to the state before the power is turned off. However, if the data in RAM 112 is broken and cannot be restored to the state before the power is turned off. The area below the special work in the RAM 112 is cleared and the set value is set to 1. At this time, an initialization command is sent from the game control board 101 to the effect control board 102.

  When the setting key switch 92 is turned on and the power is turned on, the setting value can be changed. However, before the setting value can be changed, a setting change command is sent from the game control board 101 to the effect control board. 102. By receiving the setting change command, the CPU 121 of the effect control board 102 notifies that the setting value changing operation is being performed, for example, by displaying it on the liquid crystal display 4.

  When the setting switch 91 is operated during a period during which the setting value can be changed, the setting value is updated by 1 (when the operation is further performed from the setting 6, the setting is returned to the setting 1). Then, when the setting key switch 92 is turned off after the start lever 11 is operated, the change of the setting value is confirmed. At this time, the area below the important work in the RAM 112 is cleared. If the bonus winning flag is set, it is deleted. If the bonus winning flag is set, it is deleted.

  In addition, a state command is sent from the game control board 101 to the effect control board 102 upon confirmation of the set value. This state command is also used as a status command sent to the effect control board 102 at the end of each game. . If the CPU 121 of the effect control board 102 notifies that the setting value is being changed when the state command is received, the notification ends.

  In the slot machine 1, a winning is awarded when the symbols are arranged on the active line set according to the betting number 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, the “combination” determined as the winning will be described.

  In a normal gaming state, when, for example, three “BARs” are arranged on an 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 is a game called a regular bonus game (JAC game) that is performed a predetermined number of times (for example, 12 times) or a predetermined number of times (for example, 8 times) ("JAC" is displayed on the active line). Complete: JAC prize). 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).

  For example, when three “red 7” are arranged on the active line corresponding to the bet number, 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, “JAC” is aligned on the active line with a relatively high probability (JACIN winning), and when the JACIN winning is achieved, 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.

  If, for example, three “Blue 7” s are arranged on the active line corresponding to the bet number, an RT win is made and the gaming state shifts to RT (Replay Time). In RT, the winning probability of replay in the internal lottery is higher than 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 following description, the term “bonus” includes a big bonus, a regular bonus, and RT unless otherwise specified.

  Further, in a game other than the regular bonus game, when “watermelon” or “bell” is aligned on the active line, or “cherry” appears on the left reel 3L, a small role winning is obtained. Except for the small role game and regular bonus game (including during the big bonus) provided during the big bonus period, if “JAC” is available on the active line, a replay prize will be awarded. It should be noted that in the following description, a small combination includes all combinations other than replay, JAC, and JACIN bonuses 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 winning combination as described above, the number of medals corresponding to each winning combination is paid out (except for the case where the winning combination is 50 until the number of credits reaches 50). A corresponding number of credits are accumulated as data, and in this case as well, medals are paid out as valuable value). In addition, the number of medals to be paid out is 15 in all cases, except that there are 8 bell small roles and 2 cherry small roles.

  Hereinafter, 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). The internal lottery random number (an integer from 0 to 16383) acquired for each game is used to determine the set value set by the setting switch 91, the number of bets set by the player, and each combination corresponding to the current gaming state. This is what the CPU 111 performs by adding the number of values. Winning in the internal lottery is exclusive, and a plurality of winnings are not won simultaneously in one game.

  First, acquisition of random numbers for internal lottery will be described in detail with reference to FIG. 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 referred to as the 0th bit, and the most significant bit is referred to as the 15th bit.

  FIG. 3A 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 eighth bit data signal is inverted from the H level to the L level, the level of the ninth bit data signal is alternately inverted between the H level and the 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. Hereinafter, the data signal output from the random number generation circuit 115 will be described as a random number corresponding to the logical value.

  FIG. 3B 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 an AND operation on the value of the random number obtained by exchanging the upper byte and the lower byte for the extracted random number with 8080h. Since the processing word of the CPU 111 is 1 byte, the logical product operation is actually performed sequentially on the upper byte and the lower byte. The 15th bit and the 7th bit are always 1 by this logical product operation. 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 sequentially adds the number of determination values of each combination to this. It becomes. 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 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 number of determination values used in the internal lottery will be described. In the slot machine 1 according to this embodiment, a determination indicating the type of combination and the number of determination values to be won for each combination according to the set value, the number of bets, and the game state (collectively referred to as a game situation). A table according to gaming state in which the storage location of the number of values is registered is prepared in advance.

  FIG. 4 is a diagram illustrating an example of the gaming state-specific table. The gaming state table shown in FIG. 4 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 number of bets, and may be different depending on the set value and / or the number of bets. 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. 4A shows a game state-specific table that is referred to when the game state is a regular bonus (including a big bonus). In the regular bonus, only JAC is registered as an internal lottery target. In the regular bonus, since only one bet is possible, the number of determination values is common regardless of the number of bets, and in the slot machine 1 according to this embodiment, regardless of the set value. It is common.

  FIG. 4B shows a game state-specific table that is referred to when the small bonus game in the big bonus is in the game 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” and “Bell” minor roles 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. 4C 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 number of bets is 1 or 2, the number of determination values 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 judgment values is common regardless of the set value and the number of bets.

FIG. 4D shows a table by gaming state that is referred to when the player is in the normal gaming state. In the normal gaming state, there are seven types of internal lottery targets: Big Bonus, Regular Bonus, “Watermelon” Minor, “Bell” Minor, “Cherry” Minor, Replay, and RT. It is registered. 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 number of bets is 1 or 2, the number of determination values 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 judgment 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 number of bets are the same except for replay, the address of the judgment value registered in the gaming state table referred to when the player is in RT is in the normal gaming state. It is the same as the address of the number of judgment values registered in the referenced game state table.

  FIG. 5 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 determination value number stored here is 60. Therefore, when the betting 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 the replay win in RT and the normal gaming state, respectively, but the number of determination values stored in each is different from 5120 and 2245. Therefore, the replay winning probability in the normal gaming state is different from the replay winning probability in RT.

  In addition, when the number of bets is 1, the number of judgment values for the small part of “watermelon” in the normal gaming state or RT is the address ADD + 50 when the bet number is 1, the address ADD + 52 when the bet number is 2, and the bet number is 3. If so, it is stored in the address ADD + 54. However, since the number of judgment values stored in the addresses ADD + 50, ADD + 52, and ADD + 54 are all 68, the winning probability of the small part of “watermelon” in the normal gaming state or RT is the same regardless of the number of bets. It will be a thing.

  Furthermore, when the set value is 1, the number of judgment values for the “Cherry” small role in the normal gaming state or RT is set to the address ADD + 62 if the set value is 2, and the set value is set to the address ADD + 64 if the set value is 2. Is stored in the address ADD + 66 if the set value is 4, the address ADD + 68 if the set value is 5, and the address ADD + 72 if the set value is 6. However, since the number of determination values stored in the addresses ADD + 62, ADD + 64, ADD + 66, ADD + 68, ADD + 70, and ADD + 72 are all 269, the winning probability of the small part of “Cherry” in the normal gaming state or RT is set. It will be the same regardless of the value.

  In the internal lottery, the set value, the number of bets and the determination value number of each combination according to the game state are added to the acquired random number for internal lottery, and when the overflow occurs, the combination is determined to be a win. FIG. 6 is a diagram illustrating an example of the relationship between the value of the random number for internal lottery and the number of determination values of each combination and the winning combination. FIG. 6 shows a case where the betting number 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, each with 60 judgment values, 30, 68, 3562, 269, 2245 and 16.

  With regard to the big bonus, the address for which the number of judgment values is individually stored is registered in the gaming state table. Here, the number of determination values stored in the address ADD + 32 corresponding to the betting number 3 and the set value 6 is 30. Assuming that the judgment value number of 30 is added, when the random number for internal lottery is 16324 to 16383, the addition result overflows and the big bonus is won.

  For the regular bonus, the address where the number of judgment values is individually stored is registered in the gaming state table. Here, the number of determination values stored in the address ADD + 48 corresponding to the betting number 3 and the set value 6 is 60. Assuming that 90 is added together with 30 of this judgment value number and 60 of the big bonus judgment value number, when the random number value for internal lottery is 16294-16323, the addition result overflows and becomes regular. Win a bonus.

  For the small part of “watermelon”, an address in which the number of determination values is commonly stored for the set value is registered in the table by gaming state. Here, the number of judgment values stored in the address ADD + 54 registered corresponding to the betting number 3 is 68. Assuming that 158 is added by combining the number of judgment values 68 and the number of judgment values added so far, the addition result overflows when the random number for internal lottery is 16226-16293. , Won the small role of "watermelon".

  For the small part of “Bell”, an address storing the number of determination values in common for the set value is registered in the table according to gaming state. Here, the number of determination values stored in the address ADD + 60 registered corresponding to the betting number 3 is 3562. Assuming that 3720 is added together with the number of determination values 3562 and the number of determination values added so far, the addition result overflows when the random number for internal lottery is 12664 to 16225. , Won the small role of "Bell".

  For the small part of “Cherry”, an address storing the number of determination values in common for the number of bets is registered in the table according to gaming state. Here, the number of determination values stored in the address ADD + 72 registered corresponding to the setting value 6 is 269. Assuming that 3889 is added together with the number of determination values 269 and the number of determination values added so far, the addition result overflows when the random number for internal lottery is 12395-12663. , Won the small role of "Cherry".

  For replay, an address that stores the number of determination values in common for both the set value and the number of bets is registered in the table according to gaming state. The number of judgment values stored in the address ADD + 76 registered for replay is 2245. Assuming that 6234 is added together with the number of judgment values 2245 and the number of judgment values added so far, the addition result overflows when the random number for internal lottery is 10150-12394. , Won the replay.

  As for RT, an address that stores the number of determination values in common for both the set value and the number of bets is registered in the gaming state table. The number of determination values stored in the address ADD + 78 registered for RT is 16. Assuming that 6250 is added together with the number of judgment values 16 and the number of judgment values added so far, the addition result overflows when the random number for internal lottery is 10134 to 10149. Wins RT.

  The approximate winning probabilities calculated for these roles based on the number of judgment values 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. In addition, when the value of the random number for internal lottery is 0-10133, the addition result does not overflow, and all the combinations are lost.

  In addition, when the big bonus winning flag, regular bonus winning flag or RT winning flag is already set, the big bonus, regular bonus or RT (which may be different from the set winning flag type) is won. Even if the determination is made, the big bonus winning flag, the regular bonus winning flag or the RT winning flag is not set again, and the winning is discarded.

  For the winning combination determined in the internal lottery, the winning flag for the winning combination is set in the RAM 112. In addition, a big bonus, a regular bonus (including a case where the bonus is provided during the big bonus), a big bonus medium flag indicating that the player is in the RT gaming state, a regular bonus flag, and an RT flag are also set in the RAM 112. Further, the set value and the number of bets are also stored in the RAM 112. Therefore, the configuration of the RAM 112 will be described.

  FIG. 7 is a diagram showing a memory map of the RAM 112 of the game control board 101. As illustrated, the storage area of the RAM 112 includes a stack area 112-1, a special work 112-2, a set value work 112-3, an important work 112-4, a general work I 112-5, and a general work II 112. -6, general work III 112-7, and unused area 112-8. The start address of each area is add, add + A, add + B, add + C, add + D, add + E, add + F, and add + G. The final address of the RAM 112 is add + H.

  The stack area 112-1 is an area for a stack, and a stack pointer is also included here. The special work 112-2 is a work area for generating commands and software random numbers to be transmitted to the effect control board 102. The set value work 112-3 is a work area that holds the set value. The set value that is determined at the end of the setting value change operation is data indicating the set value 1 when the RAM 112 is broken when the power is turned on. Can be put. The important work 112-4 is a work area for storing data that may cause inconvenience if cleared at the end of the big bonus.

  The general works 112-5 to 7 are work areas for storing data that may be cleared at the end of the big bonus. The general works 112-5 to 7 are divided into a general work I 112-5, a general work II 112-6, and a general work III 112-7 according to the condition that they may be cleared other than at the end of the big bonus. The unused area 112-8 is an unused area in the RAM 112.

  The general work I112-5 includes an area for setting a big bonus medium flag and an area for a counter for counting the number of payout medals in the big bonus. The general work II 112-6 includes an area for setting a regular bonus medium flag and an RT flag, an area for setting a big bonus winning flag, a regular bonus winning flag, an RT winning flag, a regular bonus, and an RT digest. An area for a counter for counting the number of games and an area for a counter for counting the number of winning games in the regular bonus are included. The general work III 112-7 includes an area for setting a winning flag of small role, replay, JAC, and JACIN.

  The entire special work 112-2 is cleared only when the RAM 112 is broken when the power is turned on. The important work 112-4 is cleared entirely only when the RAM 112 is broken when the power is turned on and when the setting value changing operation is completed. The general work I112-5 is cleared when the big bonus is completed, in addition to the case where the RAM 112 is broken when the power is turned on and the case where the setting value changing operation is completed.

  The general work II 112-6 is also cleared when the big bonus is finished, in addition to the case where the RAM 112 is broken when the power is turned on and the case where the setting value changing operation is finished. In response, the necessary part is cleared (that is, the flag is deleted and the counter is initialized). The general work III 112-7 is cleared at the end of each game regardless of whether the big bonus has ended, in addition to the case where the RAM 112 is broken when the power is turned on and the operation of changing the set value is completed. The The conditions for clearing the unused area 112-8 are the same as those for the general work III 112-7.

  From the above conditions, if the RAM 112 is broken when the power is turned on, the entire area under the special work 112-2 is cleared. When the setting value changing operation is completed, the entire area below the important work 112-4 is cleared. When the big bonus ends, the entire area below the general work I11-5 is cleared. When the game ends without completing the big bonus, the entire area below the general work III 112-7 is cleared.

  When the condition for clearing the area of the RAM 112 is established, an address corresponding to the established condition is set in a predetermined address register of the CPU 111. Here, the address according to the condition is “add + A” when the RAM 112 is broken at the time of power-on, “add + C” when the setting value changing operation is finished, “add + D” when the big bonus is finished, and “big bonus”. If the game ends without ending, it is add + F. Then, the CPU 111 clears the data at the address indicated by the address register while incrementing the set address by one from the set address until the final address add + H of the RAM 112 is reached. .

  The CPU 121 of the effect control board 102 performs various effects based on commands sent from the CPU 111 of the game control board 101. When the above initialization command or setting change command is received, the effect that has been executed up to that point is stopped, and then the RAM 122 is cleared. Further, when the setting change command is received, the fact that the setting value changing operation is being performed is displayed on the liquid crystal display 4 to notify the player. This notification is terminated by receiving the status command.

  The operation in the slot machine 1 according to this embodiment will be described below. The operation of the slot machine 1 is started when the power is turned on by turning on the main switch 94, and special processing is performed when the power is turned on.

  FIG. 8 is a flowchart showing processing executed by the CPU 111 of the game control board 101 when the power is turned on. When the power of the slot machine 1 is turned on, it is first determined whether or not the setting key switch 92 is turned on by a key operation (step S101). If the setting key switch 92 is in the OFF state, it is determined whether the data in the RAM 112 is not broken and is in a normal state (step S102). If the RAM 112 is in a normal state, the state returns to the state before the power is shut off, and the game process is started.

  If the data in the RAM 112 is corrupted, add + A is set in the address register as the start address of the area to be cleared in the RAM 112 (step S103). Then, a RAM clear process, which will be described in detail later, is performed to clear the area after add + A of the RAM 112, that is, the area under the special work 112-2 (step S104). Further, 1 is stored in the cleared set value work as an initial value of the set value (step S105). Further, an initialization command is generated and transmitted to the effect control board 102 (step S106). Then, a game process to be described later is started.

  If the setting key switch 92 is in the ON state, it is determined based on the detection signal from the door opening sensor 95 whether or not the front door is open (step S107). If the front door is open, there is a possibility that an illegal setting value change operation is about to be performed. Here, an error code indicating that a setting value changing operation has been performed with the front door open is displayed on the game number display unit 21 to notify the user. An error command may be transmitted to cause the CPU 121 of the effect control board 102 to output an error sound from the speakers 7L, 7R, and 7U, or to display an error code on the liquid crystal display 4.

  If the front door is not opened, a setting change command indicating that a setting value changing operation is being performed is generated and transmitted to the effect control board 102 (step S108). Further, the set value stored in the set value work is read out to a predetermined area and the game number display unit 51 is controlled to display the set value on the game number display unit 21 (step S109).

  Next, it is determined whether or not the start lever 11 is operated (step S110). If the start lever 11 is not operated, the process directly proceeds to step S112. If the start lever 11 has been operated, it is determined whether or not the setting key switch 92 has been turned off (step S111). If the setting key switch 92 is not turned off, the process proceeds to step S112.

  In step S112, it is determined whether the setting switch 91 has been operated. If the setting switch 91 has not been operated, the process returns to step S109. If the setting switch 91 has been operated, the set value is incremented by 1 (step S113), and it is determined whether or not the addition result is 7 (step S114). If the added result is not 7, the process returns to step S109 as it is. If the result of addition is 7, the set value is returned to the initial value 1 (step S115), and the process returns to step S109. When the setting value is updated in this way and the process returns to step S109, the updated setting value is displayed on the game number display unit 21.

  If the start lever 11 is operated in step S107 and the setting key switch 92 is turned off in step S108, add + C is set in the address register as the start address of the area to be cleared in the RAM 112 (step S116). Then, a RAM clear process, which will be described in detail later, is performed to clear the area after add + C of the RAM 112, that is, the area below the important work 112-4 (step S117). Further, the current set value is confirmed, stored in the set value work 112-3, and the game number display unit 51 is controlled to display the set value displayed on the game number display unit 21 in step S109. Erasing is performed (step S118).

  Furthermore, a state command transmission process is executed, and a state command is generated based on the current set value, the big bonus medium flag, the regular bonus medium flag and the RT flag flag stored in the RAM 112, and this is generated as an effect control board. It transmits to 102 (step S119). The state command transmitted here indicates that there is no set value stored in the set value work 112-3 in step S118 and any state of big bonus, regular bonus, or RT. This state command transmission process is the same as that executed at the end of the process of one game described below. Then, the game processing described next is started.

  When the process at the time of power-on is completed and the state before the power-off is restored or the game is started, the process for each game is repeated. In the following description, the term “game” means, in a narrow sense, from the operation of the start lever 11 until the reels 3L, 3C, 3R are stopped. However, when a game is played, the number of bets before the operation of the start lever 11 is set, and medals are paid out and the game state is shifted after the reels 3L, 3C, 3R are stopped. Is also included in the “game” in a broad sense.

  FIG. 9 is a flowchart showing processing for one game executed by the CPU 111 of the game control board 101. This process is also executed after the power is turned on and a predetermined boot process is performed, or immediately after the setting is changed by operating the setting switch 91. When the processing of one game is started, first, initial processing including processing for clearing the unused area 112-8 of the RAM 112 (by setting add + G in the address register and performing the RAM clear processing) is performed (step S201). ).

  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. BET processing for instructing start is performed (step S202). However, if the player has won a replay in the previous game, the same number of bets as the previous game are automatically set by the replay flag (the replay flag is erased at this stage), so the start lever 11 is operated as it is. You can tell the start of the game.

  When the bet number is set by the BET process and the start lever 11 is operated, a random number for internal lottery is extracted, and it is determined whether or not the winning of each above-described combination is permitted based on the extracted random number value. A lottery process is performed (step S203). In this lottery process, a winning flag is set in the RAM 112 based on each lottery result. Details of the lottery process will be described later.

  When the lottery process is completed, a reel fluctuation start process is performed (step S204). 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 S205). 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 are enabled, and each is operated by the player, thereby stopping the driving of the reel motors 3ML, 3MC, 3MR and stopping the rotation of the reels 3L, 3C, 3R according to the setting state of the winning flag. At the same time, a reel stop command is transmitted to the effect control board 102. 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.

  When the driving of each 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 S202 A winning determination process for determining whether or not is performed (step S206). If it is determined in this winning determination process that a winning combination has been won, various processes corresponding to the winnings generated on the game control board 101 are performed.

  As processing according to the winning, when the big bonus is won, the big bonus winning flag is deleted and the big bonus medium flag is set. When a regular bonus or JACIN is won, the regular bonus winning flag or JACIN winning flag is deleted and the regular bonus flag is set. When the RT is won, the RT winning flag is deleted and the RT flag is set. When a replay is won, a replay flag is set. When winning a combination other than replay, the number of payouts according to the type of winning combination is set in the general work III 112-7.

  When the winning determination process ends, a payout process is performed (step S207). In the payout process, the credit is increased by the number of payouts 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 not related to winning (including processes related to erasing winning flags other than bonus winning flags and ending bonuses) are also performed. Details of the payout process will be described later.

  When the payout process ends, a status command transmission process is performed (step S208). The state command transmission process generates a state command based on the current set value, the big bonus medium flag, and the regular bonus medium flag stored in the RAM 112, and transmits them to the effect control board 102. In step S114, Same as executed. Then, the process for one game ends, and the process for the next one game starts.

  Next, the lottery process in step S203 will be described in detail. FIG. 10 is a flowchart showing in detail the lottery process executed by the CPU 111 in step S203. 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 S301). Further, as the gaming 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 in step S202 The currently set value is acquired and stored in a predetermined area of the general work III 112-8 (step S302).

  Next, the setting state of the common flag is referred to as the processing target in order for the combination registered in the table according to gaming state corresponding to the current gaming state (step S303). As a result, it is determined whether the common flag is set for both the set value and the BET number (step S304). If the common flag is set in any case, the number of determination values stored at the address registered for the combination in the gaming state table is acquired (step S305). Then, the process proceeds to step S307.

  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 S302 for the combination is acquired. (Step S306). Then, the process proceeds to step S307. In step S307, the number of determination values acquired in step S305 or S306 is added to the random number value for internal lottery, and the result of addition is used as a new random number value for internal lottery. Here, it is determined whether or not an overflow has occurred when the number of determination values is added to the random number for internal lottery (step S308).

  If an overflow occurs, it is determined whether the combination to be processed is a big bonus, a regular bonus, or RT (step S309). If it is any of them, it is determined whether the big bonus winning flag, the regular bonus winning flag, or the RT winning flag (which may be different from the combination to be processed) is already set in the previous game. (Step S310). 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 S309 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 S310 The winning flag of the target combination is set in a predetermined area of the general works 112-5 to 7 in accordance with the type of combination (step S311). Then, the lottery process is terminated, and the process returns to the flowchart of FIG.

  If it is determined in step S308 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 S312). If there is a combination that has not yet been processed, the process returns to step S303, 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.

  Next, the random number acquisition process in step S301 will be described in detail. FIG. 11 is a flowchart showing in detail the random number acquisition process executed by the CPU 111 in step S301. In the random number acquisition process, first, an interrupt to the CPU 111 is prohibited (step S401). 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 S402).

  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 general work III 112-7 (step S403). Next, the value of the random number stored in the general-purpose register 111GR is ANDed with 8080h (step S404). 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 general work III 112-7 (step S405). Then, after permitting the interrupt prohibited in step S401 (step S406), the random number acquisition process is terminated, and the process returns to the flowchart of FIG.

  Next, the payout process in step S207 will be described in detail. FIG. 12 is a flowchart showing in detail the payout process executed by the CPU 111 in step S207. First, until the planned payout number set for the general work III 112-7 becomes 0, the winning combination is controlled by discharging the medal one by one by controlling the hopper 80 while subtracting the payout number one by one. The number of medals corresponding to is paid out to the player. However, if the number of credits has not reached 50, the number of credits is incremented by 1 instead of discharging medals one by one (step S501).

  Next, it is determined whether or not the current gaming state is RT based on whether or not the RT flag is set in the general work II 112-6 (step S502). If the current gaming state is RT, the number of digest games in the RT is counted using the game number counter provided in the general work II 112-6 (step S503). As a result of the counting, it is determined whether or not an RT termination condition has been met (step S504).

  If the RT end condition is satisfied, the RT flag set in the general work II 112-6 is erased, and the value of the game number counter provided in the general work II 112-6 is cleared (step S505). Then, the process proceeds to step S513. If the RT termination condition is not satisfied, the process proceeds to step S513.

  If the current gaming state is not RT, the current gaming state is changed to the regular bonus (including the case where it was provided during the big bonus) depending on whether the regular bonus medium flag is set in the general work II 112-6. (Step S506. If the current gaming state is not a regular bonus, the process directly proceeds to Step S510.

  If the current gaming state is a regular bonus, the number of digest games in the regular bonus is counted using the game number counter provided in the general work II 112-6, and the regular bonus is counted using the winning number counter. The number of winning games is counted (step S507). As a result of the counting, it is determined whether or not a regular bonus end condition has been met (step S508).

  If the regular bonus end condition is satisfied, the regular bonus medium flag set in the general work II 112-6 is deleted, and the values of the game number counter and the winning number counter provided in the general work II 112-6 are cleared. (Step S509). Then, the process proceeds to step S510. If the regular bonus end condition is not met, the process proceeds to step S510.

  In step S510, it is determined whether or not the current gaming state is a big bonus (including a case in which a regular bonus is in progress), depending on whether or not the big bonus flag is set in the general work I112-5. If the current gaming state is not a big bonus, the process proceeds to step S513.

  If the current gaming state is a big bonus, the number of payout medals in the big bonus is counted using the payout number counter provided for the general work I112-5 (step S511). As a result of the counting, it is determined whether or not a big bonus end condition has been met (step S512). If it is not the big bonus end condition, the process proceeds to step S513. If it is the big bonus end condition, the process proceeds to step S515.

  In step S513, since the current game is ended except for the end of the big bonus, add + F is set in the address register as the start address of the area to be cleared in the RAM 112. Then, a RAM clear process, which will be described in detail later, is performed to clear the area after add + F of the RAM 112, that is, the area under the general work III 112-7 (step S514). Then, the payout process is terminated, and the process returns to the flowchart of FIG.

  As a result, at the end of the current game, the winning flags of the small bonus, replay, JAC, and JACIN are erased, but the big bonus, regular bonus, and RT winning flags are not erased. When the big bonus medium flag, regular bonus medium flag, and RT medium flag are set, they are not deleted. In addition, the game situation of the current game, random numbers for internal lottery, and the like are cleared.

  In step S515, since the current game ends when the big bonus ends, add + D is set in the address register as the start address of the area to be cleared in the RAM 112. Then, a RAM clear process, which will be described in detail later, is performed to clear the area after add + D of the RAM 112, that is, the area below the general work I 112-5 (step S516). Then, the payout process is terminated, and the process returns to the flowchart of FIG.

  Thereby, at the end of the current game, the winning flags of the small role, replay, JAC, and JACIN are erased. Here, the big bonus, regular bonus, and RT winning flags are not set. The big bonus medium flag and the regular bonus medium flag (if set) are also deleted. Here, the RT flag is not set. In addition, the game situation of the current game, random numbers for internal lottery, and the like are cleared.

  Next, the RAM clear process in steps S104, S117, S514, and S516 described above will be described in detail. In the RAM clear process, the data at the address set in the address register of the RAM 112 is cleared. If the value of the address register is not add + H, which is the final address of the RAM 112, the value of the address register is incremented by 1, and the data at the address is cleared. When the value of the address register is “add + H”, the data at the address is cleared, and the RAM clear process ends.

  In the repetition of the game as described above, the CPU 111 of the game control board 101 shifts the game state between the normal game state, RT, regular bonus, and big bonus, and issues a command according to the progress of the game. It is transmitted to the production control board 102. On the other hand, the CPU 121 of the effect control board 102 performs an original effect based on the command received from the game control board 101. Hereinafter, processing executed by the CPU 121 of the effect control board 102 to perform various effects will be described.

  FIG. 13 is a flowchart showing command reception standby processing executed by the CPU 121 of the effect control board 102. On the side of the effect control board 102, it is determined whether or not a command sent from the game control board 101 has been received (step S601). Until the command is received, the processing in step S601 is repeated, and the command is in a standby state. When any command is received from the game control board 101, it is determined what kind of the received command is (step S602).

  If the received command type is the initialization command transmitted in step S106, an image is displayed on the liquid crystal display 4, the game effect LED 75 and / or the reel lamp 3LP is turned on, or a sound is output from the speaker 7. The present performance is stopped by the output of (No. S603). When the effect is stopped, the data in the RAM 122 is cleared (step S604). At this time, the stored setting value is also cleared, but since the setting value here is always 1, 1 is stored as the setting value in the RAM 112 (step S605). Then, the process returns to step S601.

  If the received command type is the setting change command transmitted in step S108, an image is displayed on the liquid crystal display 4, the game effect LED 75 and / or the reel lamp 3LP is turned on, or a sound is output from the speaker 7. The present performance is stopped by the output of (No. S606). When the presentation is stopped, the data in the RAM 122 is cleared (step S607). At this time, the stored setting value is also cleared, but the new setting value is notified by the status command when the setting value changing operation is completed, so it is left as it is. Further, information indicating that the setting value changing operation is being performed is displayed on the liquid crystal display 4, and the player is notified of this (step S608). Then, the process returns to step S601.

  If the received command type is the status command transmitted in step S119 or S208, the RAM 122 stores the setting value indicated by the status command and information indicating that a big bonus, regular bonus, or RT is in progress. (Step S609). Further, it is determined whether or not the liquid crystal display 4 is informed that the setting value is being changed (step S610). If it is not notified that the setting value changing operation is being performed, the process directly returns to step S601. If notified, the information displayed on the liquid crystal display 4 is deleted, and the notification that the setting value is being changed is terminated (step S611). Then, the process returns to step S601.

  If the received command type is another command, processing corresponding to the type of each command (the details are omitted because it is not related to the present invention) is executed (step S612). Thereafter, the process returns to step S601.

  As described above, in the slot machine 1 according to this embodiment, the determination value number that determines the winning probability of each combination determined according to the gaming state is stored in the address referenced from the gaming state table. Yes. The storage address may differ depending on the set value and / or the number of bets. However, 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.

  However, even if the addresses storing the set values and / or 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 are different, the determination values stored at different addresses The numbers 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, in 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 judgment values, a different number of judgment values was registered according to the set value and / or the number of bets. 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, but 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 differs depending on the set value and / or the number of bets, depending on the simulation result. 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 judgment values adjusted by the simulation becomes the same regardless of the set value and / or the number of bets, the number of judgment values is assigned to the ROM 113 by the same address assignment as that 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 in the model for mass production from the model for development, so that development from the initial design stage to the model for mass production can be easily performed. Become.

  In addition, the internal lottery adds the judgment value number of each combination registered in the gaming state table to the acquired random number for internal lottery, and depending on whether or not the result of the addition overflows, It is assumed that the presence or absence of winning is determined. For this reason, an internal lottery can be performed using the number of determination values of each combination according to the game situation as it is. It should be noted that when the winning determination table is generated before the actual winning determination is made, the loop processing is required twice, but according to this embodiment, the loop processing in the lottery processing is only required once. Thus, the processing efficiency in the entire lottery process is high.

  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, in the internal lottery, since the number of determination values corresponding to each combination is sequentially added to the value of the random number for internal lottery, the internal lottery in which each combination is won as shown in FIG. The random number value will be frozen. On the other hand, it is possible to prevent the player from aiming as much as possible by losing the periodicity of the random numbers for internal lottery by processing by software and varying the values.

  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, the setting value can be changed by turning on the power by the main switch 94 with the setting key switch 92 turned ON. At this time, a setting change command is transmitted to the effect control board 102. By receiving the setting change command, the effect control board 102 stops the effect being executed, and the data in the RAM 122 is cleared. And when changing the setting value, the effect based on the setting value before the change is not continued on the effect control board 102, so that there is no inconvenience due to such effect.

  When the effect control board 102 receives the setting change command, the liquid crystal display 4 notifies that the setting value changing operation is being performed until the state command is received. Since the setting change command is transmitted at the start of the setting value changing operation and the status command is transmitted at the end of the setting value changing operation, the setting value changing operation is performed during this time. By notifying the liquid crystal display 4, it is known from the outside that the setting value changing operation is being performed, and it is possible to prevent an unauthorized setting value changing operation from being performed.

  Even if the RAM 112 is broken when the power is turned on, the presentation control board 102 stops the running presentation by transmitting the initialization command, and the data in the RAM 122 is cleared. Therefore, the RAM 122 of the presentation control board 102 is broken. An effect different from the state on the side of the game control board 101 is not executed when the game control board 101 is not, so that annoyance due to such an effect is not felt. When the initialization command is received, 1 is stored as the set value in the RAM 122 of the effect control board 102, so that an effect different from the actual set value stored in the set value work 112-3 of the game control board 101 is executed. Can be prevented.

  When the setting key switch 92 is turned off after operating the start lever 11, a state command including information regarding the setting value is transmitted to the effect control board 102. By receiving this state command, the changed set value is also stored in the RAM 122 of the effect control board 102. As a result, the setting key switch 92 is turned off after the start lever 11 is operated, so that the setting value recognized on the side of the effect control board 102 is also reliably updated to the changed one, and the setting value changing operation In the game after ending, the production based on the changed set value can be surely performed.

  By the way, the state command transmitted to the effect control board 102 when the start lever 11 is operated and the setting key switch 92 is turned off to determine the set value is also used as the state command transmitted at the end of each game. ing. By sharing the status command in this way, the storage capacity necessary for handling a plurality of types of commands on the game control board 101 and the effect control board 102 can be reduced. Also, the processing load when the CPU 121 of the effect control board 102 determines the type of command can be reduced.

  Further, when the set value after the change is confirmed, the area below the important work 112-4 in the RAM 112 is cleared, but all winning flags of each combination are thereby deleted, a big bonus medium flag, a regular bonus medium flag Alternatively, even if the RT flag is set, the flag is deleted. Since the state command includes not only information related to the setting value but also information related to the gaming state, the gaming state recognized on the side of the effect control board 102 in the game executed after the setting value is changed is game control. There is no conflict with the gaming state recognized on the side of the substrate 101, and it is possible to reliably perform the production according to the gaming state.

  Further, the setting value can be changed by turning on the setting key switch 92 and turning on the power. However, even if this operation is performed, an error occurs if the front door is not opened. For this reason, even if a signal indicating that the setting switch 91 or the setting key switch 92 is operated by an illegal signal operation from the outside is input to the CPU 111, an error does not occur and the setting value is not changed. Even if a hole is made in the front door and the setting switch 91 or the setting key switch 92 is operated, an error occurs and the setting value is not changed. As a result, it is possible to prevent an unauthorized operation of changing the set value. In addition, since the occurrence of an error is notified to the outside by displaying an error code or the like, it is possible to prevent an illegal setting value changing operation from being performed even by this notification.

  By the way, the RAM 112 of the game control board 101 includes a stack area 112-1, a special work 112-2, a set value work 112-3, an important work 112-4, a general work I 112-5, and a general work II 112-. 6, general work III 112-7 and unused area 112-8, but some areas may be cleared depending on the established conditions. Here, when the condition for clearing the RAM 112 is established, an address is set according to the established condition, and all of the final address is cleared.

  For this reason, the process that differs depending on the established condition is only the setting of the start address of the area to be cleared, and the rest can be performed by the same RAM clear process, so that the control becomes easy. In addition to the head address of the area to be cleared, there is no need for data for finely designating the area to be cleared according to the established condition, and the amount of data for clearing the RAM 112 for each area can be reduced.

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

  In the above embodiment, an initialization command is transmitted from the game control board 101 to the effect control board 102 when the RAM 112 is broken when the power is turned on, and a setting change command is transmitted when the setting value changing operation is started. It was a thing. On the other hand, if the setting value changing operation is not informed, the initial setting is the same as when the RAM 112 is broken when the power is turned on, not the setting changing command when starting the changing operation at the time of setting. It is good also as what transmits a command.

  The CPU 121 of the effect control board 102 stores 1 as a setting value in the RAM 122 when receiving the initialization command, but when the setting value changing operation is completed, the state command is transmitted, so that the game can be started. The correct setting value is also stored in the RAM 122, and no problem occurs. In this way, by using the command transmitted at the start of the setting value changing operation also as the initialization command, it is possible to reduce the storage capacity necessary for handling a plurality of types of commands in the game control board 101 and the effect control board 102, The processing load when the CPU 121 determines the type of command can also be reduced.

  Note that the command transmitted from the game control board 101 to the effect control board 102 when the setting value changing operation is ended may be a different type of command from the state command transmitted at the end of each game. When receiving a command indicating that the setting value changing operation has been completed, the CPU 121 can immediately end the notification that the setting value changing operation is being performed.

  In the above embodiment, the notification that the setting value changing operation is being performed is started by the setting change command transmitted when the setting value changing operation is started, and is transmitted when the setting value changing operation is completed. The notification that the setting value changing operation is being performed is terminated by the status command. However, the notification that the setting value changing operation has been performed is not performed continuously in the period from the start to the end of the setting value changing operation in this way, but at any timing in the period. can do.

  For example, the CPU 121 of the effect control board 102 may notify that the setting value changing operation has been started for a predetermined time after receiving the setting change command. Further, when a command of a type different from the state command transmitted at the end of each game is transmitted at the end of the setting value changing operation, the CPU 121 of the effect control board 102 receives the command, It can also be notified that a setting value changing operation has been performed.

  In the above embodiment, the determination value number storage area uses a 2-byte area to store the determination value number in each case. 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. Thus, 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 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 number of determination values acquired in accordance with the set value or the like is sequentially added to the random number value for internal lottery, but from the value of random number for internal lottery that acquired the acquired determination value number Subtraction may be performed sequentially, and the result of subtraction may be used as a new random value for internal lottery. When the number of determination values is subtracted from the random number value for internal lottery, the 15th and 14th bits of the random number for internal lottery are set to “0”, and the subtraction result overflows (here, the subtraction result is negative) It can be determined whether or not

  In the above embodiment, regardless of whether the big bonus winning flag, regular bonus winning flag or RT winning flag is set, the big bonus and regular bonus (and RT (normal The number of determination values (when in the gaming state) is acquired to determine whether or not these roles have been won, but the big bonus winning flag, regular bonus winning flag or RT winning flag is set. Sometimes, even if it is determined that the winning combination has been won, 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, the number of determination values corresponding to these combinations may not be added to the random number for internal lottery. In this case, the number of times of performing overflow determination as a result of adding the number of determination values to the random number for internal lottery can be reduced.

  In the above embodiment, the internal lottery sequentially adds the number of judgment values of each combination according to the game situation to the acquired random value for internal lottery, and when the addition result overflows, the winning combination is won. It was supposed to be judged. On the other hand, a winning determination table in which a determination value for determining each combination as winning is determined for each game in accordance with the number of determination values for each combination according to the game situation, and the internal random number for internal lottery acquired It is good also as what performs an internal lottery by comparing this value with the determination value of each combination.

  In the case of a regular bonus, the number of bets is fixed at 1. Therefore, a winning determination table may be created only at the start of the regular bonus without creating a winning determination table for each game. A regular bonus game is played with a single bet, but in other games, a 3-card betting-dedicated machine must be played with a 3-stake bet without creating a winning determination table for each game. The winning determination table may be generated only in the game after the change operation is performed or when the game state is changed.

  In the above embodiment, different game state-specific tables are used for the normal game state and RT. However, only the replay and RT (the role of only the normal gaming state) are different in the number of determination values applied in the normal gaming state and RT. For this reason, a common gaming state table is shared between the normal gaming state and the RT, and the same replay and RT are common to the common flag indicating that the number of determination values is stored according to the set value and the number of bets. Different numbers of judgment values can be applied using flags.

  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. Alternatively, the random number value extracted from the random number generation circuit 115 may be directly acquired as a random number for internal lottery. Furthermore, it may be processed into a random number for internal lottery by a method different from the above embodiment.

  FIG. 14 is an explanatory diagram of a first modification of the process (step S301) 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 an AND 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 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 sequentially adds the number of determination values to this.

  FIG. 15 is an explanatory diagram of a second modification of the process (step S301) 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 an AND 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 sequentially adds the number of determination values to this.

  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 modified examples, 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.

  Further, 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 a random number that is 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 embodiment, information related to the progress of the game and information related to the execution of the effect, and information that needs to be changed are stored in the RAMs 112 and 122 of the game control board 101 and the effect control board 102, respectively. It was a thing. On the other hand, information that is not frequently updated, such as set values, may be stored in an electrically rewritable nonvolatile memory (EEPROM, flash memory, etc.). Corresponding to the initialization of the data in the RAMs 112 and 122 in the above embodiment, the data in such a nonvolatile memory may be initialized.

  In the above embodiment, for the RAM 112 of the game control board 101, the head address of the area to be cleared is set according to the established condition, and all the addresses up to the final address are cleared. For the RAM 122 of the production control board 102, if an area to be cleared is determined according to the established condition, the area is arranged in the same manner as the RAM 112, and all addresses from the address according to the established condition to the final address are cleared. It can be. The type of the established condition can be notified to the CPU 121 of the effect control board 102 by a command.

  In the above embodiment, there are three game states that are advantageous to the player other than the normal game state: a big bonus, a regular bonus, and RT, all of which are controlled by processing by the game control board 101. there were. On the other hand, AT (Assist Time) for notifying the type of the selected small combination and the operation order of the stop buttons 12L, 12C, 12R for winning the small combination is regarded as an advantageous game state for the player. It may be provided. This AT can be controlled by processing by the effect control board 102.

  Announcement probability of AT lottery whether or not to shift gaming state to AT, determination probability of number of AT games from transitioning gaming state to AT to end, notification for each game when gaming state is AT The probability and the like can also be different according to the set value. Since the setting value recognized by the effect control board 102 can be reliably updated by transmitting the state command when the change of the setting value is confirmed as described above, the setting value recognized by the game control board 101 Thus, the AT control can be performed on the effect control board 102 without causing any discrepancy.

  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 peripheral portion, and the symbols are driven by rotational driving of these reels 3L, 3C, and 3R. Was variably displayed. However, a device that virtually displays a symbol on a display device such as a liquid crystal display device may be used instead of the variable display device 2 described above.

  In the above embodiment, the case where the present invention is applied to a slot machine has been described as an example. On the other hand, there is a pachinko gaming machine in which the jackpot probability of the special figure game differs according to the setting value. In such a pachinko gaming machine, the setting value changing operation is performed in the same manner as the slot machine 1 described above. Is called. Also in the pachinko gaming machine, as in the slot machine 1 described above, the control circuit is configured by dividing it into a game control board that controls the progress of the game and an effect control board that controls effects such as execution of a special game. Yes.

  The command transmission at the start and end of the setting value changing operation applied to the slot machine 1 can be applied in the pachinko gaming machine. The command transmitted at these timings can also be used in combination with other commands in the pachinko gaming machine. Notifying that the setting value changing operation is being performed can also be applied in a pachinko gaming machine. It is possible to change the set value on the condition that the front door is in an open state, and it can also be applied to a pachinko gaming machine.

  In addition, whether or not to win a special game result in a pachinko machine is determined according to the random number for determining the jackpot and is determined according to the value of the acquired random number. The random number acquisition method can also be applied to acquire a jackpot determination random number. The method of acquiring random numbers for internal lottery of the modification shown in FIGS. 14 and 15 can also be applied for acquiring random numbers for determining jackpots.
