Description

  The present invention relates to a gaming machine.

  For example, a slot machine equipped with a stop button, a so-called pachislot machine, has a variable display device configured by arranging a plurality of mechanical rotating reels that display a plurality of symbols in the front display window, or a symbol on the reel on the screen. It has an electrical fluctuation display device for displaying. In response to the player's start operation, the control means drives the variable display device to rotate the reels to display the symbols in a variable manner. After a certain period of time, either automatically or by the player's stop operation, Stop rotation sequentially. At this time, when the symbols of the reels appearing in the display window are in a specific combination (winning symbol), the player is given a profit by paying out game media such as coins and medals.

  Currently, the mainstream model has a plurality of types of winning modes. In particular, when a winning combination of a predetermined combination is established, the game state is better in condition than the normal state for a predetermined period of time, instead of completing one coin payout. As such a combination, a combination that can play a game that gives a relatively large profit to the player a predetermined number of times (referred to as “Big Bonus”, hereinafter abbreviated as “BB”) and a relatively small profit to the player There is a role that can play a predetermined number of games (referred to as “regular bonus”, hereinafter abbreviated as “RB”).

  In addition, in the current mainstream models, a combination of predetermined symbols is arranged along an activated formation line (hereinafter referred to as an “effective line”), and in order to achieve a winning in which coins, medals, etc. are paid out, A combination of symbols indicating that the winning combination of the winning combination (hereinafter referred to as “internal winning combination”) is won by a winning combination (hereinafter referred to as “internal winning combination”) and the internal winning combination (hereinafter referred to as “internal winning combination”). The player is required to perform a stop operation at a timing at which the player can stop at the active line. In other words, no matter how much internal winning is made, if the timing of the stop operation of the player is bad, a winning cannot be established. That is, gaming machines that require skill in the timing of the stop operation (the high importance of technical intervention called “to push”) are currently mainstream.

  By the way, in a game arcade where such a gaming machine is installed, the model of the gaming machine is changed regularly or irregularly. The gaming machine includes a box-shaped cabinet and a front door that opens and closes the cabinet. In the model change, members that form the appearance of the gaming machine, that is, members provided around the front door are mainly used. Exchanged. Specifically, an operation unit operated by a player, a medal tray for storing paid-out medals, a display panel and lamps for displaying game information, or a decorative panel for decorating a gaming machine are exchanged. The Conventionally, when changing the model, it is necessary to replace the entire gaming machine even if some members are replaced.

  However, if the entire gaming machine is replaced every time the model is changed, it will be very expensive. The gaming machine includes many common members that do not depend on the model, and when changing the model, it is preferable to replace only necessary members while leaving such common members as much as possible. In addition, game machines are required to make such model changes easily and promptly. For this reason, in recent years, it has been desired to develop a gaming machine that takes into account that the model change as described above is performed in advance.

Thus, for example, there is a gaming machine in which a plurality of constituent members are unitized and these units are attached to a front door. (See Patent Document 1).
According to this gaming machine, constituent members such as a display panel and lamps constituting the external appearance are unitized, and when changing the model, the unit including a member that needs to be replaced is replaced as a unit. This speeds up the work of changing the model and reduces the cost required for replacement.

Further, since the attachment base 120 is attached to the sub-base 100 so as to hold the ROM cartridge 300 by the main control circuit unit 180, it is possible to prevent the ROM cartridge 300 from dropping from the sub-control circuit unit 140. Furthermore, by removing the mounting base 120 from the sub base 100, the ROM cartridge 300 can be easily replaced without removing the sub control circuit unit 140.
Further, since the mounting base 120 that supports the main control circuit unit 180 is mounted on the sub-base 100, a plurality of members such as stop buttons 7L, 7C, 7R provided on the front door 2 and the main control circuit unit 180 are connected. The wiring between them can be shortened.

Further, since the reel unit base 121 is provided between the main control circuit base 131 and the sub base 100, the reel unit base 121 and the main control circuit base 131 are connected to the sub control base 100 only by attaching the main control circuit base 131 to the sub base 100. It can be almost fixed by being sandwiched between 100.
Since the reel unit base 121 is provided with the claws 124L and 124R and the wall 108, the main control circuit base 131 can be easily fixed to the reel unit base 121 without using a special tool.
At this time, since the end of the ROM socket 142 is provided between the main control circuit base 131 and the reel unit base 121, the end of the ROM socket 142 can be connected to the main unit by simply attaching the main control circuit base 131 to the reel unit base 121.

Further, since the main control circuit unit 180 is fixed by the claw 139, it can be fixed without using a special tool.

  FIG. 7 shows a symbol row in which 21 types of symbols represented on each reel 3L, 3C, 3R are arranged. Each symbol is assigned a code number “00” to “20”, and is stored (stored) in a ROM 32 (FIG. 8) described later as a data table. On each of the reels 3L, 3C, 3R, “red 7 (design 91)”, “blank (design 92)”, “bell (design 93)”, “watermelon (design 94)”, “BAR (design 95) A symbol row composed of symbols "", "Replay (symbol 96)", and "Cherry (symbol 97)" is shown. Each reel 3L, 3C, 3R is rotationally driven so that the symbol row moves in the direction of the arrow in FIG.

  “Blank” is basically a symbol that is not directly related to the formation of a role. That is, even when “blanks” are displayed along any one of the active lines, the player is not provided with benefits such as paying out medals, automatic insertion of medals, and the transition of the gaming state described later. .

  Here, BB1, BB2, cherry, bell, watermelon, and replay are provided in the role of the embodiment. Further, BB (including BB1 and BB2) is an accessory continuous operation device related to the first type special accessory.

  The combination (combination data) is basically control information in which a profit given to a player is associated with a symbol combination, stop control of the reels 3L, 3C, 3R, switching (transition) of the game state, It is used for giving game value.

  In addition, the gaming state of the embodiment basically includes a general gaming state and an RB gaming state. The gaming state can be basically distinguished by the type of an internal lottery table described later used for determining the internal winning combination. Specifically, the gaming state can be distinguished by the type of a role that may be won internally, the probability of internal winning, and the like.

  The general gaming state includes a carryover section having a carryover combination and a non-carryover section having no carryover combination. In the carryover section, there is no internal winning for the bonus, and in the non-carryover section, the bonus may be won internally. Therefore, the carryover section and the non-carry-over section are basically different gaming states. The carryover combination is a combination that allows the corresponding symbol combinations to be arranged along the active line over one or a plurality of games (permitted according to the internal winning combination).

  The general gaming state is a gaming state in which an expected value of a so-called “play rate” (a gaming value given to a player with respect to a unit gaming value bet on a game) is smaller than one. As will be described later, in the general gaming state of the embodiment, the expected value when the inserted number (BET number) is 3 is 0.4768.

  The RB gaming state is basically a gaming state constituted by a game in which the “first type special character” is operating.

  The RB gaming state can be identified by turning on or off the RB operating flag. The RB operating flag is information for identifying whether or not the gaming state is the RB gaming state. The condition that the RB operating flag is updated to ON is that a BB operating flag described later is updated to ON when BB1 or BB2 is established.

  The condition for updating the RB operating flag to be off is that the possible number of games is 0, the possible number of winnings is 0, or that the BB operating flag is updated to off. The number of possible games is the number of unit games that can be played in the RB gaming state. The number of possible winnings is the number of times that a prize can be won in the RB gaming state.

  The BB in-operation flag is information for identifying whether or not the BB operating flag is in an advantageous state generated by establishment of BB. The condition for updating the BB operating flag to ON is that BB1 or BB2 is established. The condition for updating the BB operating flag to OFF is that the number of medals paid out exceeds the payable number. The payout possible number is the number of medals that can be paid out in a game (game) from when the BB operating flag is updated to on until the BB operating flag is updated to off.

  Here, the relationship between the BB operating flag and the RB operating flag from when the BB operating flag is updated to on until it is updated to off will be described. When BB1 or BB2 is established, the BB operating flag is updated to ON. When this BB operating flag is updated to ON, the RB operating flag is updated to ON. When the possible number of games is 0 or the possible number of winnings is 0, the RB operating flag is updated to OFF. If the BB operating flag is ON, the RB operating flag is updated to ON again.

  When the condition that the BB operating flag is updated to OFF is satisfied, the BB operating flag is updated to OFF. However, when the BB operating flag is updated to OFF, the RB operating flag is OFF. Updated to Therefore, when the BB operating flag is on, the RB operating flag is updated to on. That is, after the establishment of BB1 or BB2, the RB gaming state is set until the BB operating flag is updated to OFF.

  FIG. 8 is based on a main control circuit 71 for controlling game processing operations in the gaming machine 1, peripheral devices (actuators) electrically connected to the main control circuit 71, and control commands transmitted from the main control circuit 71. A circuit configuration including a liquid crystal display unit 5a, speakers 9L and 9R, LEDs 101 and a sub-control circuit 72 for controlling lamps 102 is shown.

  The main control circuit 71 includes a microcomputer 30 disposed on a circuit board as a main component, and is added with a circuit for random number sampling. The microcomputer 30 includes a CPU 31 that performs a control operation according to a preset program (FIGS. 16 to 22 described later), and a ROM 32 and a RAM 33 that are storage means.

  Connected to the CPU 31 are a clock pulse generator 34 and a frequency divider 35 for generating a reference clock pulse, and a random number generator 36 and a sampling circuit 37 for generating a random number to be sampled. As a means for random number sampling, random number sampling may be executed in the microcomputer 30, that is, on the operation program of the CPU 31. In that case, the random number generator 36 and the sampling circuit 37 can be omitted, or can be left as a backup for the random number sampling operation.

  The ROM 32 of the microcomputer 30 has an internal lottery table (FIG. 13 to be described later) used for determination of random number sampling performed every time the start lever 6 is operated (start operation), and the reel stop mode according to the stop button operation. A stop table group for determining the control, various control commands (commands) for transmission to the sub control circuit 72, and the like are stored. The sub control circuit 72 does not input commands, information, or the like to the main control circuit 71, and communication is performed in one direction from the main control circuit 71 to the sub control circuit 72. Various information is stored in the RAM 33. For example, a flag, an internal winning combination, a carryover combination to be described later, information on the current gaming state, and the like are stored.

  In the circuit of FIG. 8, the main actuators whose operation is controlled by a control signal from the microcomputer 30 are a BET lamp (1-BET lamp 9a, 2-BET lamp 9b, maximum BET lamp 9c), and an information display section. 18, a hopper (including a drive unit for payout) 40 that stores medals and pays out a predetermined number of medals according to a command from the hopper drive circuit 41, and a stepping motor 49L that rotates the reels 3L, 3C, 3R. 49C and 49R.

  In addition, a motor drive circuit 39 that drives and controls the stepping motors 49L, 49C, and 49R, a hopper drive circuit 41 that drives and controls the hopper 40, a lamp drive circuit 45 that drives and controls the BET lamps 9a, 9b, and 9c, and the information display unit 18 A display unit driving circuit 48 that controls the driving of the CPU 31 is connected to the output unit of the CPU 31. Each of these drive circuits receives a control signal such as a drive command output from the CPU 31 and controls the operation of each actuator.

  The main input signal generating means for generating an input signal necessary for the microcomputer 30 to generate a control command includes a start switch 6S, a 1-BET switch 11, a 2-BET switch 12, a maximum BET switch 13, There are a C / P switch 14, a medal sensor 22S, a reel stop signal circuit 46, a reel position detection circuit 50, and a payout completion signal circuit 51.

  The start switch 6S detects the operation of the start lever 6 and outputs a game start command signal. The medal sensor 22S detects medals inserted into the medal insertion slot 22. The reel stop signal circuit 46 generates a stop signal (stop command signal) in response to the operation of each stop button 7L, 7C, 7R. The reel position detection circuit 50 receives the pulse signal from the reel rotation sensor and supplies a signal for detecting the position of each reel 3L, 3C, 3R to the CPU 31. The payout completion signal circuit 51 generates a signal for detecting completion of the medal payout when the count value of the medal detection unit 40S (the number of medals paid out from the hopper 40) reaches the designated number data.

  In the circuit of FIG. 8, the random number generator 36 generates a random number belonging to a certain numerical range, and the sampling circuit 37 samples one random number at an appropriate timing after the start lever 6 is operated. By using the random numbers sampled in this way, for example, an internal winning combination is determined based on an internal lottery table (FIG. 13 described later) stored in the ROM 32, for example. The internal symbol combination (internal symbol combination data) is that the corresponding symbol combination and the profit given to the player are indirectly associated with each other through the stop control mode corresponding to the internal symbol combination I can say that.

  After the rotation of the reels 3L, 3C, 3R is started, the number of drive pulses supplied to each of the stepping motors 49L, 49C, 49R is counted, and the counted value is written in a predetermined area of the RAM 33. From the reels 3L, 3C, 3R, reset pulses are obtained every rotation, and these pulses are input to the CPU 31 via the reel position detection circuit 50. The count value of the drive pulse counted in the RAM 33 is cleared to “0” by the reset pulse thus obtained. As a result, the RAM 33 stores the count value corresponding to the rotational position within the range of one rotation for each of the reels 3L, 3C, 3R.

  A symbol table (not shown) is stored in the ROM 32 in order to associate the rotational positions of the reels 3L, 3C, and 3R with the symbols drawn on the outer peripheral surface of the reel. In this symbol table, a code number that is sequentially given for each fixed rotation pitch of each reel 3L, 3C, 3R with reference to the rotation position where the reset pulse is generated, and a corresponding code number are provided. A symbol code indicating the displayed symbol is associated with the symbol.

  Further, a symbol combination table (FIG. 10 described later) is stored in the ROM 32. In this symbol combination table, a symbol combination corresponding to a combination, a medal payout number corresponding to the symbol combination, and a determination code thereof are associated with each other. The symbol combination table is referred to when the left reel 3L, the central reel 3C, and the right reel 3R are stopped and when the display combination is confirmed after all the reels 3L, 3C, and 3R are stopped. The display combination is a combination (established combination) corresponding to the symbol combination arranged along the display line.

  Based on the lottery process (such as the internal lottery process) based on the random number sampling, the CPU 31 selects the operation signal sent from the reel stop signal circuit 46 at the timing when the player operates the stop button 7L, 7C, 7R, and the selected signal. Based on the stop table, a signal for stopping the reels 3L, 3C, 3R is sent to the motor drive circuit 39.

  In the stop mode indicating the winning combination, the CPU 31 supplies a payout command signal to the hopper driving circuit 41 and pays out a predetermined number of medals from the hopper 40. At this time, the medal detection unit 40S counts the number of medals to be paid out from the hopper 40, and when the count value reaches a designated number, a medal payout completion signal is input to the CPU 31. Thereby, CPU31 stops the drive of the hopper 40 via the hopper drive circuit 41, and complete | finishes a medal payout process.

The image control microcomputer 81 transmits a command to the sound / lamp control circuit (mSub) 72b via the serial port 82 at every predetermined timing. In the sound / lamp control circuit (mSub) 72b, only the sound / lamp output is performed mainly in accordance with the command transmitted from the image control circuit (gSub) 72a (excluding the volume adjustment control described later). .

  The sound / lamp control circuit (mSub) 72b includes a sound / lamp control microcomputer 91, a serial port 92, a program ROM 93, a work RAM 94, a sound source IC 95, a power amplifier 96, and a sound source ROM 97.

  The sound / lamp control microcomputer 91 includes a CPU, an interrupt controller, and an input / output port (a serial port is shown). The CPU provided in the sound / lamp control microcomputer 91 performs sound / lamp output processing according to the control program stored in the program ROM 93 based on the command transmitted from the image control circuit (gSub) 72a. The sound / lamp control microcomputer 91 is connected to LEDs 101 and lamps 102. The sound / lamp control microcomputer 91 transmits an output signal to the LEDs 101 and the lamps 102 in response to a command transmitted from the image control circuit (gSub) 72a at a predetermined timing. As a result, the LEDs 101 and the lamps 102 emit light in a predetermined manner according to the effect.

  The serial port 92 receives a command or the like transmitted from the image control circuit (gSub) 72a. The program ROM 93 stores a control program executed by the sound / lamp control microcomputer 91 and the like. The work RAM 94 is configured as a temporary storage means for work when the sound / lamp control microcomputer 91 executes the control program described above.

  The sound source IC 95 generates a sound source based on the command transmitted from the image control circuit (gSub) 72 a and outputs the sound source to the power amplifier 96. The power amplifier 96 is an amplifier, and speakers 9L and 9R are connected to the power amplifier 96. The power amplifier 96 amplifies the sound source output from the sound source IC 95 and outputs the amplified sound source from the speakers 9L and 9R. The sound source ROM 97 stores sound source data (phrase etc.) for generating a sound source.

  The sound / lamp control microcomputer 91 is connected to a volume control unit 103. The volume control unit 103 can be operated by employees of the game hall and the like, and the volume output from the speakers 9L and 9R is adjusted. The sound / lamp control microcomputer 91 performs control to adjust the sound output from the speakers 9L and 9R to the input volume based on the input signal transmitted from the volume control unit 103.

  The symbol combination table will be described with reference to FIG.

  The symbol combination table includes a display combination corresponding to a combination of symbols stopped and displayed at each of the three symbol stop positions connected by the effective line, and information on a payout number for each inserted number corresponding to the display combination. This symbol combination table is referred to when the payout number is determined according to the symbol combination displayed along the active line after all reels 3L, 3C, 3R are stopped.

  When “cherry-ANY-ANY” is arranged along the active line, the display combination is cherry, and 15 medals are paid out regardless of the number of inserted coins. When “bell-bell-bell” is arranged along the valid line, the display combination becomes bell, and 15 medals are paid out regardless of the number of inserted coins. When “watermelon-watermelon-watermelon” are arranged along the active line, the display combination becomes watermelon, and eight medals are paid out regardless of the number of inserted coins. When “Replay-Replay-Replay” is arranged along the active line, the display combination is replayed and medals are automatically inserted.

  When “BAR-BAR-BAR” is arranged along the active line, the display combination is BB1, and the gaming state is shifted to the RB gaming state by turning on the BB operating flag. When “red 7-red 7-red 7” are arranged along the active line, the display combination is BB2, and the gaming state shifts to the RB gaming state when the BB operating flag is turned on.

  The internal winning combination, carryover combination, operating flag, and gaming state storage area (storage area) will be described with reference to FIG.

  (1) of FIG. 11 shows an internal winning combination storage area (display combination storage area). In this internal winning combination storing area, information (data) of the internal winning combination is stored (stored) in an internal winning combination storing area consisting of 1 byte. In the internal winning combination storage area, bit 0 (first bit) is a storage area corresponding to cherry. Bit 1 (second bit) is a storage area corresponding to the bell. Bit 2 (third bit) is a storage area corresponding to a watermelon. Bit 3 (fourth bit) is a storage area corresponding to replay.

  Bit 4 (the fifth bit) is a storage area corresponding to BB1. Bit 5 (sixth bit) is a storage area corresponding to BB2. Bit 6 (seventh bit) and bit 7 (eighth bit) are unused storage areas. In the internal winning combination storing area, the one corresponding to the bit which is 1 (combination) is the internal winning combination. The internal winning combination storage area stores a logical sum of data corresponding to the internal winning combination determined in step S51 of FIG. 19 described later and data stored in a carryover combination storing area described later (described later). Step S53 in FIG.

  The internal winning combination (internal winning combination data) is basically information for identifying a mode of stop control and identifying a combination that can be a display combination (a combination that can be permitted as a display combination). It can be said that the internal symbol combination is indirectly associated with the corresponding symbol combination and the profit given to the player through the stop control mode corresponding to the internal symbol combination.

  (2) of FIG. 11 shows a carryover combination storage area. In this carryover combination storage area, carryover combination information is stored in a carryover combination storage area consisting of 1 byte. In the carryover combination storage area, bit 4 (fifth bit) is a storage area (storage area) corresponding to BB1. Bit 5 (sixth bit) is a storage area corresponding to BB2. Bit 0 (first bit), bit 1 (second bit), bit 2 (third bit), bit 3 (fourth bit), bit 6 (seventh bit), and bit 7 (eighth bit) are: This is an unused storage area.

  In the carryover combination storage area, a logical product of the data corresponding to the internal winning combination determined in step S51 of FIG. 19 to be described later and bonus check data is calculated, and the result of this logical operation is stored in the carryover combination storage area. The logical sum with the obtained data is stored (step S52 in FIG. 19 described later). The bonus check data is information for identifying whether or not BB1 or BB2 is carried over, and is “00110000” data consisting of 1 byte.

  (3) of FIG. 11 shows the operating flag storage area. In this operating flag storage area, the operating flag information is stored in the operating flag storage area consisting of 1 byte. In the operating flag storage area, bit 0 (first bit) is a storage area corresponding to the BB operating flag. Bit 1 (second bit) is a storage area corresponding to the RB operating flag. Bit 2 (3rd bit), bit 3 (4th bit), bit 4 (5th bit), bit 5 (6th bit), bit 6 (7th bit), and bit 7 (8th bit) are This is an unused storage area.

  (4) of FIG. 11 shows a game state storage area. In this gaming state storage area, gaming state information is stored in a gaming state storage area consisting of 1 byte. In the gaming state storage area, bit 1 (second bit) is a storage area corresponding to the RB gaming state. Bit 0 (first bit), bit 2 (third bit), bit 3 (fourth bit), bit 4 (fifth bit), bit 5 (sixth bit), bit 6 (seventh bit), and bit 7 (8th bit) is an unused storage area.

  Here, information corresponding to the gaming state is stored in the gaming state storage area. When the data stored in the game state storage area is 0, that is, all the bits are 0 (“00000000”), the general game state is indicated.

  The internal lottery table determination table will be described with reference to FIG.

  The internal lottery table determination table includes an internal lottery table (FIG. 13 to be described later) corresponding to the gaming state and information on the number of lotteries.

  Here, in the case of the general gaming state, an internal lottery table for general gaming state ((1) in FIG. 13 described later) is selected, and basically 6 is determined as the number of lotteries (described in FIG. 19 described later). Step S41). The number of lotteries is the number of times required for determining the internal winning combination. Specifically, the number of lotteries is the number of times (maximum number of times) of calculating XD described later. However, in the carryover section, the number of lotteries determined to be 6 is updated to 4 (step S43 in FIG. 19 described later).

  The internal lottery table will be described with reference to FIG. The internal lottery table is provided for each gaming state and includes lottery value information corresponding to the winning number for each inserted number.

  (1) of FIG. 13 shows an internal lottery table for a general gaming state. (2) of FIG. 13 shows the internal lottery table for RB gaming state.

  In the determination of the winning number based on the internal lottery table (lottery), XD is calculated in descending order from the same winning number as the number of lotteries determined for each gaming state until the winning number becomes zero. If X-D becomes negative, the corresponding winning number is won. X is the extracted random value. D is a cumulative lottery value obtained by accumulating lottery values from the winning number where the calculation is started to the current winning number. The number of times X-D is calculated (the maximum number) is the same as the number of lotteries determined in the internal lottery table determination table of FIG. In addition, when XD is calculated up to the maximum number of times and does not become negative, the winning number is 0 (lost). The internal winning combination is determined on the basis of the winning number, the gaming state, the number of inserted games, and the internal winning combination determining table (FIG. 14 described later).

  For example, when the inserted number is 3 in the non-carry-over section in the general gaming state and the random number value extracted from the range of 0 to 65535 is 500, first, X (500) -D (96) for the winning number 6 Calculate The result of this calculation is positive and the winning number 6 is incorrect. Next, X (500) −D (96 + 96) is calculated for the winning number 5. The result of this calculation is positive and the winning number 5 is incorrect.

  Next, X (500) −D (96 + 96 + 8980) is calculated for the winning number 4. The result of this calculation is negative. Therefore, if the extracted random number X is 500 when the inserted number is 3 in the non-carry-over section, the winning number 4 is won. In this case, based on an internal winning combination determination table (described later, FIG. 14), the replay corresponding to the winning number 4 becomes the internal winning combination.

  Here, in the carryover section, since the number of lotteries is updated to 4 (step S43 in FIG. 19 described later), any of the winning numbers 5 to 6 is not determined as the winning number. That is, in the carryover section, BB1 or BB2 is not determined as an internal winning combination.

  An internal winning combination lose indicates that the internal lottery did not win the combination associated with the player's profit. Further, the loss in the embodiment is not a combination associated with the game value. In addition, the symbol combination corresponding to the loss as an internal winning combination can be considered as an arbitrary symbol combination different from the symbol combinations corresponding to a plurality of predetermined combinations. The corresponding symbol combination is not provided.

  The internal winning combination determination table will be described with reference to FIG.

  The internal winning combination determination table includes information (data) of an internal winning combination (flag information) corresponding to the winning number. The flag is represented by a binary number. The data of the internal winning combination corresponding to the winning number determined based on the internal lottery table is the logic of the data stored in the carryover combination storing area ((2) of FIG. 11) in step S53 of FIG. Used for sum. This logical sum is stored in the internal winning combination storing area ((1) in FIG. 11).

  Here, the expected values K and L (expected values not considering so-called “missing”) of the number of medals to be paid out per unit (unit game value) bet on one game (playing rate) will be described. . The expected values K and L are basically calculated by calculating {Payout number / BET number} × {Probability of internal winning} for each internal winning combination corresponding to the winning number of the internal lottery table, and adding these. It can be calculated. The internal winning probability is a value obtained by dividing the lottery value by 65536.

  The expected value K is an expected value of the number of medals to be paid out per medal bet on one game in the general gaming state. The expected value L is the expected value of the number of medals to be paid out per medal bet on one game in the general gaming state, and the BB operating flag after the BB operating flag is updated to ON when the bonus is established. This is obtained in consideration of medals to be paid out in the RB gaming state until is updated off. The general gaming state is composed of a carry-over section and a non-carry-over section. However, in any section, medals are not paid out due to the establishment of a bonus, so the general game is not distinguished between the carry-over section and the non-carry-over section. The expected value in the state can be calculated.

In the general gaming state, assuming that the expected value when the inserted number is 1 is K1, the expected value when the inserted number is 2 is K2, and the expected value when the inserted number is 3 is K3,
K1 = {15/1} × {1 / (65536-8980)} (cherry)
+ {15/1} × {1 / (65536-8980)} (bell)
+ {8/1} × {1 / (65536-8980)} (watermelon)
= 0.0007
K2 = {15/2} × {4 / (65536-8980)} (cherry)
+ {15/2} × {4 / (65536-8980)} (bell)
+ {8/2} × {4 / (65536-8980)} (watermelon)
= 0.0013
K3 = {15/3} × {1024 / (65536-8980)} (Cherry)
+ {15/3} × {4096 / (65536-8980)} (bell)
+ {8/3} × {512 / (65536-8980)} (watermelon)
= 0.4768
It becomes.

  The expected value L can be calculated on the assumption that BB1 and BB2 are display combinations associated with the same number of payouts as the expected value T of the net increase in medals in the RB gaming state generated by the establishment of the bonus. it can. The net increase number is a value obtained by subtracting the number of inserted medals (BET number) from the number of paid out medals.

In consideration of medals to be paid out in the RB gaming state from when the BB operating flag is updated to ON due to the establishment of the bonus, until the BB operating flag is updated to OFF, If the expected value is L1, the expected value when the inserted number is 2 is L2, and the expected value when the inserted number is 3 is L3,
L1 = {15/1} × {1 / (65536-8980)} (cherry)
+ {15/1} × {1 / (65536-8980)} (bell)
+ {8/1} × {1 / (65536-8980)} (watermelon)
+ {T / 1} × {4 / (65536-8980)} (BB1)
+ {T / 1} × {4 / (65536-8980)} (BB2)
= 0.0482
L2 = {15/2} x {4 / (65536-8980)} (cherry)
+ {15/2} × {4 / (65536-8980)} (bell)
+ {8/2} × {4 / (65536-8980)} (watermelon)
+ {T / 2} × {24 / (65536-8980)} (BB1)
+ {T / 2} × {24 / (65536-8980)} (BB2)
= 0.1439
L3 = {15/3} × {1024 / (65536-8980)} (Cherry)
+ {15/3} × {4096 / (65536-8980)} (bell)
+ {8/3} × {512 / (65536-8980)} (watermelon)
+ {T / 3} × {96 / (65536-8980)} (BB1)
+ {T / 3} × {96 / (65536-8980)} (BB2)
= 0.857
It becomes.

The expected value T of the net increase in medals in the RB gaming state (period in which the BB operating flag is on) generated by the establishment of the bonus is obtained for the case where the bell is established in all games in the RB gaming state. In this case, the RB gaming state continues until the bell is established 24 times during the period when the BB operating flag is on and the medal payout number reaches 360 (until the payout possible number 350 is exceeded). Therefore, by subtracting the inserted number 24 from the payout number 360,
T = 360-24
= 336
It becomes.

  Here, when the replay is established, it is possible to play the next game without betting medals, but it can be considered that the medal is not paid out. Therefore, the internal lottery value 8980 of replay is subtracted from 65536 in the denominator of the probability of internal winning.

  Of the expected values K1 to K3 in the general gaming state, the expected value K3 of the game with the inserted number 3 is relatively largest, and the expected value K1 of the game with the inserted number 1 is relatively smallest. Also, regarding the expected values L1 to L3 in the general gaming state in consideration of the establishment of BB1 and BB2, the expected value L3 of the game with the inserted number 3 is relatively largest, and the expected value L1 of the game with the inserted number 1 is relative Is the smallest.

  With reference to FIG. 15, the bonus operation time table will be described.

  The bonus operating time table includes, for each display combination, information on an operating flag (to be described later), a bonus end number counter (to be described later), a game possible number, and a winning possible number. This bonus operating time table is referred to in the process of step S33 in FIG. 18 described later and the process of step S102 in FIG. 22 described later.

  The operating flag is information for identifying an operating gaming state (current gaming state). The operating flag includes a BB operating flag and an RB operating flag corresponding to the display combination.

  The bonus end number counter is a counter that counts the number of medals paid out in a game from when the BB operating flag is updated to on until the BB operating flag is updated to off.

  The control operation of the main control circuit 71 will be described with reference to the main flowcharts shown in FIGS.

  First, the CPU 31 performs initialization (step S1). Specifically, initialization of the storage contents of the RAM 33, initialization of communication data, and the like are performed. Subsequently, a storage location (address) of predetermined storage contents (information of a predetermined storage area (for example, an area for storing an internal winning combination and an area for storing game state information)) in the RAM 33 at the end of the game is set. (Step S2), the process proceeds to Step S3.

  In step S3, a bonus operation monitoring process described later with reference to FIG. 18 is performed, and the process proceeds to step S4. In this process, when the BB operating flag is on, processing is performed to update the RB operating flag to on so that the RB gaming state continues even after the RB gaming state ends. In step S4, medal insertion / start check processing is performed, and the process proceeds to step S5. In this processing, processing such as updating the number of BETs is performed based on inputs from the start switch 6S, the medal sensor 22S, or the BET switches 11-13.

  In step S5, a random number value for lottery is extracted, and the process proceeds to step S6. The random value extracted in this process is used in the internal lottery process described later. In step S6, a game state monitoring process is performed, and the process proceeds to step S7. More specifically, in this step S6, the gaming state is monitored based on the operating flag (RB operating flag, BB operating flag), and an internal lottery table corresponding to the gaming state in step S41 of FIG. Is stored in the RAM 33 (game state storage area). In step S7, an internal lottery process which will be described later with reference to FIG. 19 is performed, and the process proceeds to step S8. In step S8, a start command is transmitted, and the process proceeds to step S9 in FIG. The start command includes information such as a gaming state and an internal winning combination, and is transmitted to the sub-control circuit 72.

  In step S9 in FIG. 17, it is determined whether 4.1 seconds have elapsed since the start of the previous reel rotation. When this determination is YES, the process proceeds to step S11, and when NO, the process proceeds to step S10. In step S10, waiting time digestion processing (wait) is performed, and the process proceeds to step S11. Specifically, a process of invalidating an input based on an operation for starting a player's game until a predetermined time (for example, a predetermined second (eg, 4.1 seconds)) has elapsed since the start of the previous game. I do. In step S11, the start of rotation of all reels is requested, and the process proceeds to step S12.

  In step S12, a reel stop control process which will be described later with reference to FIG. 20 is performed, and the process proceeds to step S13. In step S13, a display combination search process is performed, and the process proceeds to step S14. The display combination search process is to set a flag for identifying a display combination (a winning combination) based on the symbol stop mode of the display window 4C. In step S14, a display combination command is transmitted, and the process proceeds to step S15.

  In step S15, a medal payout process is performed, and the process proceeds to step S16. In step S16, the bonus end number counter is updated based on the payout number, and the process proceeds to step S17. If the bonus end number counter is 1 or more, the counter is subtracted according to the number of medals paid out. In step S17, it is determined whether or not the RB operating flag or the BB operating flag is on. When this determination is YES, the process proceeds to step S18, and when NO, the process proceeds to step S19.

  In step S18, a bonus end check process described later with reference to FIG. 21 is performed, and the process proceeds to step S19. In step S19, a bonus operation check process described later with reference to FIG. 22 is performed, and the process proceeds to step S2 in FIG.

  The bonus operation monitoring process will be described with reference to FIG.

  First, the CPU 31 determines whether or not the BB operating flag is on (step S31). When this determination is YES, the process proceeds to step S32, and when this determination is NO, the process proceeds to step S4 in FIG. In step S22, it is determined whether or not the RB operating flag is on. When this determination is YES, the process proceeds to step S4 in FIG. 15, and when NO, the process proceeds to step S33.

  In step S33, RB operation processing is performed based on the bonus operation table (FIG. 15), and the process proceeds to step S4 in FIG. Specifically, the RB operating flag is updated to ON, and the possible game number and the possible winning number are stored in the RAM 33. In steps S31 to S34, if the BB operating flag is on, the RB operating flag is updated to ON when the RB gaming state ends, and processing is performed so that the RB gaming state starts again. It has been broken.

  The internal lottery process will be described with reference to FIG.

  First, based on the internal lottery table determination table (FIG. 12), the CPU 31 determines the type of the internal lottery table (FIG. 13) and the number of lotteries according to the gaming state (step S41), and proceeds to step S42. In step S42, whether the data (information) stored in the carryover combination storage area is 0, that is, whether all the first to eighth bits of the carryover combination storage area ((2) in FIG. 11) are 0. Is determined. When this determination is YES, the process proceeds to step S44, and when this determination is NO, the process proceeds to step S43. Here, when this determination is YES, it is a case of a non-carry-over section in the general gaming state, and when it is NO, it is a case of a carry-over section. In step S43, the number of lotteries is changed to 4, and the process proceeds to step S44.

  In step S44, the same value as the number of lotteries is set as the winning number, and the process proceeds to step S45. Specifically, the winning number is 6 in the non-carry-over section in the general gaming state, the winning number is 4 in the carry-over section in the general gaming state, and the winning number corresponding to the gaming state is set in the register.

  In step S45, the internal lottery table determined in step S41 is referred to, a lottery value is acquired based on the winning number and the number of inserted sheets, and the process proceeds to step S46. In step S46, the lottery value (D) is subtracted from the random value (X), and the process proceeds to step S47. Here, the lottery value (X) is accumulated according to the lottery value corresponding to the winning number. In step S47, it is determined whether or not a digit has been set. Specifically, it is determined whether or not the calculation result of X−D is negative. When this determination is YES, the process proceeds to step S51, and when this determination is NO, the process proceeds to step S48.

  In step S48, 1 is subtracted from the winning number, and the process proceeds to step S49. In step S49, the number of lotteries is decremented by 1, and the process proceeds to step S50. In step S50, it is determined whether the number of lotteries is zero. When this determination is YES, the process proceeds to step S51, and when this determination is NO, the process proceeds to step S45.

  In step S51, with reference to the internal winning combination determination table (FIG. 14), an internal winning combination is determined based on the winning number, and the process proceeds to step S52. In step S52, the logical product of the data corresponding to the internal winning combination and the bonus check data is calculated, and the logical sum of the result of this logical operation and the data in the carryover combination storage area is stored in the carryover combination storage area. Move. In step S53, the logical sum of the data corresponding to the internal winning combination and the data in the carryover combination storing area is stored in the internal winning combination storing area, and the process proceeds to step S8 in FIG.

  Here, for example, when the internal winning combination is a Bell small combination and BB1 is carried over, the data corresponding to the internal winning combination is “00000010”, and the data stored in the carryover combination storing area is “00010000”. . In this case, in step S62, the logical product of the data corresponding to the internal winning combination (“00000010”) and the bonus check data (“00110000”) is “00000000”. The logical sum of the result of this logical operation (“00000000”) and the data (“00010000”) stored in the carryover combination storage area is “00010000”. This result (“00010000”) is stored in the carryover combination storage area.

  In step S53, the logical sum of the data corresponding to the internal winning combination (“00000010”) and the data stored in the carryover combination storage area (“00010000”) is “00010010”. This result (“00010010”) is stored in the internal winning combination storing area.

  The reel stop control process will be described with reference to FIG.

  First, the CPU 31 determines whether or not a valid stop button has been pressed (step S71). When this determination is YES, the process proceeds to step S72, and when this determination is NO, the process proceeds to step S71. In step S72, the number of sliding frames is determined, and the process proceeds to step S73. In step S73, based on the determined number of sliding symbols and the current symbol position, a scheduled stop position (a position to stop the symbol) is determined, and the process proceeds to step S74. In step S74, a reel stop command is transmitted, and the process proceeds to step S75. In this determination of the number of sliding frames, since the maximum number of sliding frames (for example, 4 frames) that can be determined in advance is determined, the reel stops within a predetermined time after the stop operation is performed.

  In step S75, the symbol identifier of the center line is stored in the symbol storage area, and the process proceeds to step S76. In step S75, an identifier for identifying the type of the symbol stopped at the middle line (center line) is stored in the symbol storage area provided in the RAM 33. In step S76, it is determined whether or not there is a rotating reel. When this determination is YES, the process proceeds to step S71, and when it is NO, the process proceeds to step S13 in FIG.

  The bonus end check process will be described with reference to FIG.

  First, the CPU 31 determines whether or not a winning is achieved (step S91). When this determination is YES, the process proceeds to step S92, and when this determination is NO, the process proceeds to step S97. In step S92, it is determined whether or not the bonus end number counter is zero. When this determination is YES, the process proceeds to step S93, and when this determination is NO, the process proceeds to step S95.

  In step S93, processing at the end of RB is performed, and the process proceeds to step S94. Specifically, clearing the RB operating flag, clearing the number of possible winnings and the number of possible games are performed. In step S94, processing at the end of BB is performed, and the process proceeds to step S19 in FIG. Specifically, the BB operating flag is cleared, the bonus end number counter is cleared, and the like.

  In step S95, 1 is subtracted from the number of possible winnings, and the process proceeds to step S96. In step S96, it is determined whether the number of possible winnings is zero. When this determination is YES, the process proceeds to step S99, and when it is NO, the process proceeds to step S97. In step S97, 1 is subtracted from the possible number of games, and the process proceeds to step S98. In step S98, it is determined whether or not the possible number of games is zero. When this determination is YES, the process proceeds to step S99, and when it is NO, the process proceeds to step S19 in FIG. In step S99, processing at the end of RB is performed, and the process proceeds to step S19 in FIG.
