Description

The present invention relates to a slot machine , and more specifically, a player can use a valuable value owned by a player as a bet number, and can variably display a plurality of types of identification information including big bonus identification information. The present invention relates to a slot machine that includes a variable display device having a plurality of variable display units in which valid hit lines are set by input, and that ends one game by stopping after the variable display units start variable .

In this type of slot machine , for example, a player inputs a bet number to bet on the game result of one game by inputting a valuable value owned by the player such as a coin , for example , Next, when the variable display device is variably started by performing a predetermined start operation and then stopped, and the stop result of the variable display device becomes a predetermined winning combination display mode, etc. There is a configuration in which a predetermined value is given to a player and one game is finished. When the player plays the game again, as described above, the player's own valuable value is input, the bet number is input and set, and the start operation is performed to start the next game. Was composed.

On the other hand, in order to maintain the soundness of the game in the slot machine, it is necessary to suppress the betting ability to some extent, and for that purpose, it is necessary to suppress the magnitude of the bet number input per unit time to some extent.
Therefore, for example, it is conceivable that the upper limit of the number of bets that can be input in one game is set to be low so that a large number of bets cannot be input. However, if the number of bets entered is small, the player's loss will be small if no winning occurs, but the player's gaming result value when winning will be small. There is a disadvantage that the game is less interesting and less thrilling.
Therefore, a re-game that allows a game to be played without inputting and using the valuable value owned by the player as a bet number is set as one of the roles, and the stop result of the variable display device indicates the re-game identification corresponding to the re-game role. It can be considered that a re-game is generated when the display mode of the re-game combination by information is obtained.
In such a configuration, it is possible to carry over the previous bet number without using the bet number and use it again, and the number of bets that can be input per unit time without reducing the fun of the slot machine game. By substantially suppressing the above, an effect of suppressing excessive consumption of the valuable value owned by the player per unit time is produced.
However, in this type of slot machine, it is possible to display the winning combination set based on the winning determination as the stop result of the variable display device, but the predetermined stoppable range can be determined from the identification information corresponding to the winning combination. When the player performs a stop operation at a location outside the range, the result of stopping the combination is not displayed even if the winning flag is set.
As a result, although the re-game winning flag is set, the player's stop operation timing is bad, and the re-game identification information that enables the occurrence of the re-game is not displayed as a stop result. May occur. When such a large number of misses occur, there arises a drawback that the above-mentioned re-game purpose of suppressing excessive consumption of the player's valuable value per unit time cannot be sufficiently achieved.

The present invention has been conceived in view of such circumstances, and an object of the present invention is to provide a slot machine capable of moderately suppressing the shooting performance using a re-game function .

The present invention according to claim 1 enables a game by using the valuable value owned by the player as the number of bets, and can variably display a plurality of types of identification information including big bonus identification information. A slot machine that includes a variable display device having a plurality of variable display units in which an effective hit line is set by, and that ends the game by stopping after the variable display units start variable.
When the stop result on the effective hit line of the plurality of variable display portions at the end of the base game becomes the display mode of the big bonus combination by the big bonus identification information, the transition to the big bonus is performed and the base game is ended. When the stop result on the effective winning line of the plurality of variable display portions becomes a small combination display mode by the small combination identification information of the plurality of types of identification information, the transition to the big bonus is not performed. The small game winning is generated, and the stop result on the effective hit line of the plurality of variable display portions at the end of the base game is a display mode of the re-game combination based on the re-game identification information of the plurality of types of identification information Game control means for generating a re-game that allows a game without using the valuable value owned by the player as a wager number when
Start operation means for performing an operation of starting one game;
Extraction means for extracting numerical information from a plurality of numerical information in a predetermined numerical range when the start operation means is operated;
Definition data storing a plurality of pieces of numerical information in the predetermined numerical range and definition data defining correspondence relationships between each of a plurality of types of combinations including the big bonus combination, the small combination, and the re-game combination Storage means;
Whether the numerical information extracted by the extracting means is the numerical information corresponding to one of the multiple types of roles defined in the definition data, so that the multiple types of roles are won Determining means for determining whether or not;
Setting means for setting a winning flag corresponding to the combination determined to be won by the determining means;
Stop operation means for stopping the variable display unit;
Any one of the pieces of identification information located within a predetermined stoppable range based on the identification information displayed at a predetermined position on the effective hit line of the variable display unit when the stop operation means is operated. Variable display control means for controlling the identification information to stop at the predetermined position based on the winning flag set by the setting means,
Informing means for notifying that the big bonus combination is won when the big bonus winning flag is set by the setting means;
When the result of stopping the plurality of variable display portions becomes a display mode for improving the winning rate of the re-game combination, the plurality of types of the definition data used in the normal game are determined from predetermined first definition data. Re-game combination winning in which the winning rate of the re-game combination is improved by changing only the ratio of the numerical information corresponding to the re-game combination to the second definition data higher than the first definition data After controlling to the rate improvement state, when the number of games after the start of the control to the re-game role winning rate improvement state reaches a predetermined number of games, the re-game role winning to end the re-game role winning rate improvement state A rate improvement state control means,
The game control means reduces the setting means when the stop result on the effective winning line of the plurality of variable display portions is not the display mode of the combination corresponding to the winning flag set by the setting means. When the bonus winning flag is set, the small bonus winning flag is deleted, and when the big bonus winning flag is set by the setting means, the big bonus winning flag is not erased and carried over to the next game,
The arrangement of the identification information of the plurality of variable display portions is an arrangement configuration in which the re-game identification information always exists within the stoppable range,
The variable display control means includes
When only the re-game winning flag is set, the game uses the identification information displayed at a predetermined position on the effective hit line of the variable display unit when the stop operation means is operated as a reference. The re-game identification information located within the predetermined stoppable range is stopped at the predetermined position,
In the next game that has progressed without erasing the big bonus winning flag set by the setting means, the setting means sets the re-game winning flag so that the re-game winning flag is added to the big bonus winning flag. In the game, when the stop operation means is operated, the identification information displayed at a predetermined position on the effective hit line of the variable display unit is used as a reference in the game. Control for stopping the re-game identification information located within a predetermined stoppable range at the predetermined position is performed.

According to the first aspect of the present invention, the player's investment amount per unit time is moderately suppressed by preventing the re-game identification information from being lost when the re-game winning flag is set. Can be prevented from becoming excessively high.
In addition, when both the big bonus winning flag and the re-game winning flag are set, the occurrence of the re-game is prioritized over the occurrence of the big bonus, and the big bonus winning flag is set. The bonus will be carried over after the next game. As a result, it is possible to increase the time from the start of the game until the player gains profits from the occurrence of the big bonus rather than giving priority to the occurrence of the big bonus over the occurrence of the re-game. A player's profit per hour can be suppressed. Therefore, the occurrence of the re-game not only can suppress the investment amount per unit time of the player (so-called IN) from the viewpoint of the number of bets, but also in the set state of both the big bonus winning flag and the re-game winning flag. By giving priority to the occurrence of re-games, it is possible to delay the timing of the occurrence of a large profit (so-called OUT) given to the player by the occurrence of a big bonus, and only a relatively small amount of IN from the viewpoint of the number of bets In addition, it is possible to suppress a relatively large amount of OUT from the viewpoint of the big bonus profit, and it is possible to suppress the shooting property appropriately from both IN and OUT.
Further, when the big bonus winning flag is set, it is notified that the big bonus combination is won, so that the player's expectation for the big bonus can be improved.
In addition, the frequency of occurrence of re-games is increased by shifting to the re-game winning percentage improvement state, and the player can continue the game without extremely reducing the valuable value on hand. As a result, it is possible to prevent as much as possible from increasing the shooting performance while providing the fun of the game with the big bonus.
In addition, since the re-game combination winning rate improvement state occurs when the stop result of the plurality of variable display portions becomes a display mode for improving the winning rate of the re-game combination, It is possible to further improve the player's expectation for the stop result of the variable display section.
Furthermore, since the re-game combination winning rate improvement state ends when the number of games after the start of the control to the re-game combination winning rate improvement state reaches a predetermined number of games, the shooting performance can be moderately suppressed. At the same time, it is easy for the player to predict in advance the end time of the re-game winning ratio improvement state.
In addition, the second definition data for improving the re-game combination winning rate state improves only the re-game combination winning ratio compared to the normal first definition data, and includes other combinations including big bonuses. It does not change the winning percentage. Therefore, by controlling to the re-game combination winning rate improvement state, the player's expectation for, for example, a big bonus other than the re-game combination is not reduced. As described above, not changing the winning ratio of, for example, the big bonus other than the re-game role can prevent the reduction of the player's expectation for the big bonus due to the decrease of the winning ratio of the big bonus, but the re-game winning rate The transition to the improved state does not increase the winning ratio of the big bonus, so the regame winning ratio improving state does not induce the big bonus. However, between the occurrence of the re-game role winning rate improvement state and the end of the re-game role winning rate improvement state due to the big bonus winning, the player waits for the big bonus winning while reducing the investment Thus, the player's expectation for the next big bonus can be improved without excessively improving the shooting ability.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is an overall front view showing an example of a slot machine according to the present invention. The machine frame 1A of the slot machine 1 is provided with a front frame 1B, which is an example of a cover member, so that it can be opened and closed. A display window is provided at a predetermined position on the front side of the upper part of the front frame. The display window is provided with variable display portions 5L, 5C, and 5R for allowing the player to visually recognize identification information such as symbols variably displayed by the variable display device 90 (see FIG. 2). Each of the left variable display portion 5L, the middle variable display portion 5C, and the right variable display portion 5R is configured to have a size capable of variably displaying the identification information in three upper and lower stages. The front frame 1B is normally locked in a closed state, and the front frame 1B can be opened by being unlocked by operating a game attendant by inserting a predetermined key into the door opening / closing key hole 3a. Become. Then, the door switch 44 detects the open / closed state of the front frame 1B.

A card processing device 76 is installed on the left side of the slot machine. This card processing device 76 is for enabling a game by the slot machine 1 using the valuable value of the player's possession specified by the record information recorded on the common card. The common card is a third-party issued prepaid card that can be used at game arcades nationwide that are members of the common card system. When a player plays a game, the player first purchases a common card from a common card vending machine or the like, and when the usable indicator 77 is lit or blinking, the purchased common card is inserted into the common card insertion / discharge port. 79. Then, the record information of the inserted common card is read by the card reader / writer 78. The card processing device 76 is provided with a card processing device control unit 80 composed of a microcomputer having a CPU, ROM, RAM, etc., and the card processing device control unit 80 controls the card reader. Then, when the player presses the lending button 71, the operation is detected by the lending switch 72, and a predetermined number of coins are paid out from the coin payout outlet 29 into the coin storage tray 30 based on the detection output. The valuable value corresponding to the paid-out coin is reduced from the valuable value specified by the record information of the common card inserted into the card insertion / discharge slot 79. Then, when the insertion instruction lamp 19 is lit or blinking, the player inserts the coin from the coin insertion slot 18. The insertion instruction lamp 19 is turned off when three coins are inserted (when one coin is inserted in a bonus game described later). When the player inserts a coin and presses the start lever 12, the variable display device 90 is variably started, and a plurality of types of identification information are variably displayed by the variable display portions 5L to 5R. Next, when the player presses each of the stop buttons 9L, 9C, 9R, the variable display of the corresponding variable display portions 5L, 5C, 5R is stopped. If the player does not press any of the stop buttons 9L to 9R, the variable display device 70 is automatically controlled to stop after a predetermined time. A predetermined game value can be given if one game is finished by one variable stop that is stopped after the variable display device 90 is variably started and the display result at the time of the variable stop becomes specific identification information as will be described later. It becomes.

  In the case of a normal game (coin game) which is not a credit game, which will be described later, if the player inserts one coin from the coin insertion slot 18 and presses the start lever 12, the middle stage in the variable display sections 5L to 5R. The effective line (the hit line) of one horizontal row of becomes effective. When the identification information displayed when the variable display device 90 is stopped has a predetermined combination of identification information on the active line in the horizontal row in the middle row, a big bonus game or bonus game described later is established. A predetermined game value such as starting or paying out a predetermined number of coins can be given. On the other hand, if the player presses the start lever 12 with two coins inserted into the coin insertion slot 18, the three rows of effective lines in the variable display portions 5L to 5R become effective, and the variable display device 90 is stopped. When the display result at that time is a combination of specific identification information on any one of the three horizontal rows of active lines, a predetermined game value can be given. Furthermore, if the player presses the start lever 12 with three coins inserted into the coin insertion slot 18, a total of five rows of three rows in the variable display portions 5L to 5R and two rows on the diagonal diagonal line are displayed. If the valid line becomes valid and a specific combination of identification information is established on any of the five valid lines, a predetermined game value can be given. That is, if the player inserts one coin and presses the start lever 12, a so-called one-sheet betting game is activated, one active line is activated, two coins are inserted and the start lever 12 is moved. If the pressing operation is performed, a so-called two-wager game is obtained, and three active lines are valid. If three coins are inserted and the start button 12 is pressed, a so-called three-wager game is obtained, and five active lines are provided. Everything is valid.

  The slot machine 1 in this embodiment is configured so as to be able to play a so-called credit game. A credit game means that a large number of coins are inserted in advance and accumulated as valuable value, or coins awarded as prizes are accumulated as valuable value, and are accumulated in advance without inserting coins one by one. It is a game that plays using valuable value. The player can switch from the normal game to the credit game by pressing the game switch button 16 once, and can switch from the credit game to the normal game by pressing the game switch button 16 again. . In the case of a credit game, the value for a total of 50 coins can be stored in advance, and when the credit operation button 14 is pressed once, the above-described single-wager game is obtained. By pressing twice, the above-described two-wager game is obtained, and by pressing the credit operation button three times, the above-described three-wager game is obtained. A credit operation button is provided corresponding to each bet amount, and a one-bet game is made by pressing the one-card bet credit operation button, and two bets are made by pressing the two-bet credit operation button. The game may be configured such that a three-wager game can be made by pressing the three-wager credit operation button. The coin insertion slot 18 or the credit operation button 14 constitutes a bet number input means for inputting a bet number which is a number corresponding to the value of the player's own valuable value bet on the game result of the one game. Yes.

In the figure, reference numerals 21 to 23 denote active line display lamps, and only the effective line display lamps corresponding to the active lines that become active in accordance with the number of bets described above are lit or blinked, and it is determined which active line is active. Configured to be recognized by a person. 11L, 11C, and 11R are a left operation effective lamp, a middle operation effective lamp, and a right operation effective lamp, respectively, and light up to indicate that the pressing operation of the corresponding stop buttons 9L, 9C, and 9R has been effectively received. Or for blinking display. In addition, in addition to or instead of lamp display, this operation validity notification may be notified by sound. Further, notification may be made by switching a lamp or the like from a blinking state to a lighting state or changing a color. In the figure, 25 is a game number / variable display, which displays the value of a big bonus game counter or bonus game (regular bonus game) counter, which will be described later, and displays the number of big bonus games or bonus games currently being executed. It is configured to be able to. The number-of-games / variable indicator 25 is a variable for lottery-displaying whether or not the display result of the variable display device such as the probability of occurrence of a big bonus game changes to a specific display mode as will be described later. It is also used as a display. For example, the number-of-games / variable indicator 25 can display 10 kinds of variable display from “00” to “99”. The probability variation control is performed twice at “77” and the probability variation is once at “33”. In other displays, control is performed so as not to change the probability. In the figure, reference numeral 70 denotes a lending permission indicator, which indicates whether or not coins can be lent using the player's valuable value specified by the common card inserted into the card insertion / discharge slot 79. It is for lighting or blinking display. Reference numeral 75 is a remaining amount display for displaying a player's own valuable value (remaining amount) specified based on the record information of the common card inserted through the card insertion / discharge port 79. Reference numeral 73 denotes a return button. When the player presses the return button 73, the operation is detected by the return switch 74, and the common card inserted in the card insertion / discharge port 79 is detected based on the detection signal. It is discharged and returned to the player. Reference numeral 26 denotes a credit display for displaying the number of coins as a valuable value stored at the time of a credit game. Reference numeral 27 denotes a payout amount display for displaying the number of coins given when a winning is achieved. In the case of a normal game that is not a credit game, when a winning is achieved, a predetermined number (for example, 15) of coins is paid out from the coin payout exit 29 to the coin storage tray 30, and in the case of a credit game. The number of coins given within a range not exceeding the storage upper limit (50) is stored. In addition, when the upper limit (50 sheets) of the memory is exceeded, the surplus coins are paid out into the coin storage tray 30.

  A front panel 2 is provided below the display window 71 on the front side of the slot machine 1. Also, when the big bonus game, which will be described later, is over and the game is over and the game is in a mode with game over, which will be described later, the game cannot be resumed unless a reset operation is performed. The reset operation is performed by inserting a predetermined key into the reset keyhole 3b and operating it in the counterclockwise direction. An operation of the reset keyhole 3b in the clockwise direction is detected by the reset switch 4, and the slot machine 1 is reset based on the detection output so that the game can be performed again. In the figure, reference numeral 28 denotes a speaker, which generates a sound effect at the time of winning a prize, a big bonus game, a bonus game, an alarm sound at the time of abnormality, or the like. Further, a plurality of game effect lamps 24 are provided above the display window 71 on the front side of the slot machine 1 and are lit or blinked when a big bonus game or a bonus game is generated. Reference numeral 20 in the figure denotes a game overlamp, which is lit or flashed when the slot machine is stopped (game over). As described above, the game in one game of the slot machine 1 depends on how many coins are inserted from the coin insertion slot 18 before the start lever 12 is pressed or how many times the credit operation button 14 is pressed in the credit game. The number of bets on the outcome is determined. In the figure, reference numeral 64 denotes a re-game display lamp, which is lit when a re-game is possible as will be described later.

FIG. 2 is an overall rear view showing a partial internal structure of the slot machine. The variable display device 70 has a plurality (three in the drawing) of reels 6L, 6C, and 6R, and reels 6L, 6C, and 6R are provided with reel drive motors 7L, 7C, and 7R that are stepping motors. The reels 6L to 6R are rotated and stopped by the reel driving motors 7L to 7R. On the outer periphery of each of the reels 6L to 6R, identification information including a plurality of types of symbols as shown in FIG. 3 is drawn. The identification information drawn on the outer periphery of the reel is variably displayed by the variable display portions 5L to 5R.
In the figure, reference numerals 8L, 8C and 8R denote reel position detection sensors for detecting the reference position of each reel, and the reference position is detected by the reel position detection sensors 8L to 8R every time the reels 6L to 6R make one rotation. Detected and a detection output is derived. If the player presses the stop buttons 9L, 9C, 9R, the operation is detected by the stop switches 10L, 10C, 10R. When the player presses the game switch button 16, the operation is detected by the game switch 17. When the player presses the start lever 12, the operation is detected by the start switch 13. When the player presses the credit operation button 14, the operation is detected by the credit switch 15. If a key operation for probability setting is performed using a specific key possessed by a manager of the game hall or the like, this is detected by the key switch 43, and in that state, the door switch 44 (for example, a micro switch is configured). ) Is activated, and the game hall manager or the like can change and set the winning probability by operating the activated door switch 44. In the figure, 24 is a game effect lamp, 25 is a game number display device, 26 is a credit display device, 27 is a payout number display device, and 21 to 23 are active line display lamps. The payout number display 27 also displays an error code for specifying the cause of the error when an error occurs, as will be described later.

  Coins inserted from the coin insertion slot 18 are guided to the coin selector 32 through the coin path 31. The coin selector 32 determines whether the inserted coin is a valid coin or an improper coin such as a fake coin. If the coin is an improper coin, the flow path switching solenoid 33 is excited to switch the flow path. The improper coin is returned from the coin payout exit 29 (see FIG. 1) through the return path 34. On the other hand, when the inserted coin is an appropriate coin, the appropriate coin is guided to the coin take-in path 35 side, and the coin is taken into the coin storage tank 37 and stored. The coin take-in path 35 is provided with an inserted coin sensor 36 as an example of a betting number input detecting means, and a coin passing through the coin take-in path 35 is detected by the inserted coin sensor 36. On the other hand, when more than three coins are inserted during a normal game that is not a credit game, or when the number of credits reaches 50 during a credit game, the flow path switching solenoid 33 is excited and the flow path is switched. The fourth and subsequent inserted coins are returned through the return path 34.

  The surplus coins that can no longer store coins after the coin hopper 37 is full are stored in the surplus coin storage tank 41 through the surplus coin guide path 40. The surplus coin storage tank 41 is provided with a full tank sensor 42. When the surplus coin storage tank 41 becomes full, it is detected by the full tank sensor 42 and becomes full based on the detection output. Error processing is performed to notify the effect. The attendant at the game hall collects the coins in the surplus coin storage tank 41 of the slot machine 1 that is full based on the notification that the tank is full.

A coin payout motor 38 is provided at a lower portion of the coin hopper 37, and the coin payout motor 38 rotates to allow coins in the coin hopper 37 to be transferred from the coin payout outlet 29 into the one-address coin storage tray 30. Discharged. The coins to be discharged are detected by the payout coin sensor 39, and when a predetermined number (for example, 15) of payout coins is detected, the coin payout motor 38 is controlled to stop. In the case of a credit game, when the number of coins stored as a credit score exceeds the upper limit number (for example, 50) stored, the coins exceeding the number are paid out into the coin storage tray 30 by the coin payout motor 38. Is done. In the figure, reference numeral 45 denotes a control unit for controlling the slot machine, which includes a microcomputer and the like. In the figure, reference numeral 65 denotes a power switch, which allows the slot machine 1 to be turned on and off.

  FIG. 3 is a developed view showing symbols (symbol marks) as identification information drawn on the outer periphery of each of the left, middle, and right reels. The numbers shown on the left side of FIG. 3 are symbol numbers, and 21 symbols (symbol marks) of 0 to 20 are attached to the outer periphery of each reel. FIG. 3A shows a symbol drawn on the outer periphery of the left reel 6L (see FIG. 2), and FIG. 3B shows a symbol drawn on the outer periphery of the middle reel 6C. (C) is a diagram showing a pattern drawn on the outer periphery of the right reel 6R. If the display result when the variable display device 70 is stopped becomes “AAA” on the active line (winning line) corresponding to the number of bets, the big bonus game is started and 15 coins are paid out. On the other hand, if it becomes “BBB” on the valid active line, a bonus game is started and 15 coins are paid out. Furthermore, if “CCC” or “DDD” is set on the active line, a combination of symbols of the small role is established and 15 coins are paid out. If it becomes “EEE” on the active line, a small role is established and eight coins are paid out. If the left symbol and the middle symbol are both “F” on the active line, a small combination is established and six coins are paid out. On the active line, if only the left symbol becomes “F”, a small role is established and three coins are paid out.

  Further, during a big bonus game or a normal game that is not in a bonus game, if three "G", that is, "JAC" are arranged on the hit line, a re-game is established and coins are inserted as described later. Instead, the variable display device 70 is variably started again only by performing a start operation. Also, if three “G” s are aligned on the active line during the big bonus game, the bonus game is started. Also, if three “G” s are aligned on the winning line during the bonus game, the bonus game is won and 15 coins are paid out. It should be noted that the effective winning line where a winning occurs during the bonus game is only one horizontal row in the middle of the variable display section. In addition, when there are a plurality of active lines corresponding to the number of bets, if the combination of symbols from which the above-mentioned coins are paid out is simultaneously established on a plurality of active lines, the combination of symbols on each active line In principle, coins corresponding to the total number of coins to be awarded are awarded. However, since the upper limit of coins given in one game is determined to be 15, the coins after the 16th are invalid when the number exceeds 15.

  FIG. 4 is a side view of each reel 6L, 6C, 6R. The outer periphery of each reel 6L, 6C, 6R has a predetermined center in the circumferential direction around the rotation center of each reel 6L, 6C, 6R (corresponding to the axis of the drive shaft of the reel drive motors 7L, 7C, 7R). Each corner is divided into 21 areas, and in each area, each pattern shown in FIG. 3 is drawn with each area as one symbol range.

  The numbers 0 to 20 shown in FIG. 4 correspond to the symbol numbers 0 to 20 of each symbol shown in FIG. 3, and each symbol has its center position at the position indicated by the broken line in FIG. It is drawn. The arc shown on the left side of FIG. 4 is the display area of each variable display portion 5L, 5C, 5R. As is clear from FIG. 4, each variable display portion 5L, 5C, 5R has three vertical display directions. A symbol is displayed.

And a readable RAM 48. Further, an I / O port 49 for matching the signal between the CPU 46 and the external circuit, an initial reset circuit 51 that gives a reset pulse to the CPU 46 when the power is turned on, and a clock generation circuit 52 that gives a clock signal to the CPU 46. A pulse frequency dividing circuit (interrupt pulse generating circuit) 53 that divides the clock signal from the clock generating circuit 52 and periodically gives an interrupt pulse to the CPU 46; and an address decode circuit that decodes address data from the CPU 46 54.

  The CPU 46 can execute the operation of the interrupt control routine in accordance with the interrupt pulse periodically given from the pulse frequency dividing circuit 53. The address decode circuit 54 decodes the address data from the CPU 46 and gives a chip select signal to the ROM 47, RAM 48, I / O port 49, and sound generator 50, respectively.

  In this embodiment, the programmable ROM 47 is used for the ROM 47 so that the contents of the ROM 47 can be rewritten, that is, if necessary, the program for the CPU 46 stored therein can be changed. Then, the CPU 46 gives control signals to the above-described reel drive motor and various display lamps in accordance with a program stored in the ROM 47 and in response to input of each control signal described below.

First, when the door switch 44 is operated by a game hall manager or the like, the operation signal is given to the I / O port 49 via the switch / sensor circuit 55. When the key switch 43 is operated by a predetermined key, the operation signal is input to the I / O port 49 via the switch / sensor circuit 55. With this key switch, the game mode and the probability setting mode are switched. When the probability setting mode is set, the winning probability is input and set based on the detection output of the door switch 44 as described later. When the reset switch 4 is operated by a predetermined key, the operation signal is input to the I / O port 49 via the switch / sensor circuit 55. A pressing operation of the game switching button 16 is detected by the game switching switch 17, and the detection signal is input to the I / O port 49 via the switch / sensor circuit 55. The operation of the credit operation button 14 is detected by the credit switch 15, and the detection output is input to the I / O port 49 via the switch / sensor circuit 55. The pressing operation of the start lever 12 is detected by the start switch 13, and the detection output is input to the I / O port 49 via the switch / sensor circuit 55. The detection signals of the left stop button 9L, middle stop button 9C, and right stop button 9R are detected by the left stop switch 10L, middle stop switch 10C, and right stop switch 10R, and the respective detection signals are passed through the switch / sensor circuit 55. To the I / O port 49. Coins inserted from the coin insertion slot 18 are detected by the inserted coin sensor 36, and the detection output is input to the I / O port 49 via the switch / sensor circuit 55. When a coin is paid out by the coin payout motor 38 (see FIG. 2), the payout coin is detected by the payout coin sensor 39, and the detection output is input to the I / O port 49 via the switch / sensor circuit 55. Is done. When the surplus coin storage tank 41 becomes full with the stored coins, the fact is detected by the full sensor 42, and the detection output is input to the I / O port 49 via the switch / sensor circuit 55. The left reel 6L, the middle reel 6C, and the right reel 6R rotate so that the reference position values (notches and the like are formed) of the respective reels are the left reel position sensor 8L, the middle reel position sensor 8C, and the right reel position sensor 8R. If detected, each detection signal is input to the I / O port 49 via the switch / sensor circuit 55.

  The control unit 45 outputs control signals to the following various devices. First, a reel drive control signal (stepping motor step signal) is output to the left reel drive motor 7L, the middle reel drive motor 7C, and the right reel drive motor 7R via the motor circuit 56, respectively. A coin payout control signal is output to the coin payout motor 38 via the motor circuit 57. A solenoid excitation control signal is output to the flow path switching solenoid 33 via the solenoid circuit 58. Display control signals are output to the game number display 25, the credit display 26, and the payout display 27 through the LED circuit 59, respectively. Via the lamp circuit 60, the game effect lamp 24, the input instruction lamp 19, the effective line display lamps 21, 22, 23, the left operation effective lamp 11L, the middle operation effective lamp 11C, the right operation effective lamp 11R, the game overlamp 20, A lamp control signal is output to each game display lamp 64. A sound generation control signal is output to the speaker 28 via the sound generator 50 and the amplifier 61.

  A card processing device control unit 80 provided in the card processing device 76 is electrically connected to the control unit 45. A coin lending mode signal for designating whether or not coin lending is possible is output from the I / O port 49 to the card processing device controller 80 via the information output circuit 67. In response to the signal, the card processing device control unit 80 lights or blinks the lending permission indicator 70 in the lending mode. When the player presses the lending button 71, the operation signal is input from the lending switch 72 to the card processing device control unit 80, and a coin lending command signal is sent from the card processing device control unit 80 via the information input circuit 66. Input to the I / O port 49. In response to the signal, the control unit 45 outputs a control signal for paying out a predetermined number of coins to the coin payout motor 38 to perform control for lending a predetermined number of coins. When a predetermined number of coins are lent, a coin lending signal indicating that a predetermined number of coins has been lent is output from the I / O port 49 to the card processing device controller 80 via the information output circuit 67. When the common card is inserted into the common card insertion / discharge port 79 and read by the card reader / writer 78, a control signal for displaying the player's own valuable value (remaining amount) specified based on the read data is displayed on the card. It is output from the processing device control unit 80 to the remaining amount indicator 75. Further, on condition that the card processing device control unit 80 and the control unit 45 are electrically connected, a card processing device connection signal is sent from the card processing device control unit 80 via the information input circuit 66 to the I / O port. 49. In the control unit 45, the game is activated on the condition that the card processing device connection signal is input. That is, when the card processing device connection signal is not input, the reel drive motors 7L, 7C, and 7R are not controlled to be driven, or coins are not lent even if the lending button 71 is pressed. To disable the game. A predetermined direct current is supplied from the power supply circuit 62 to the various devices and control circuits described above. Further, the RAM 48 is configured to be supplied with a current for storing data from the backup power source 63, and even if the current is not supplied from the power source circuit 62 due to a power failure or the like, the probability set value and the game state are set. Can be stored for a predetermined period.

  6 to 9 and FIGS. 12 to 17 are flowcharts for explaining the operation of the control circuit shown in FIG.

FIG. 6A shows a processing program executed when the power is turned on. The slot machine power is turned on when the amusement hall starts business, and the slot machine is turned on during business hours, for example, when the power is turned off and then restored again due to a power failure. Can be considered. In FIG. 6, first, in step S (hereinafter simply referred to as S) 1, it is determined whether or not the reset switch is ON. This reset switch 4 is used to select whether to set the game over (stop) to function or not to function. If the reset switch 4 is ON, the game over from S3. It is set so that the game over (stopping) does not function by setting the mode to no. On the other hand, if the reset switch 4 is OFF, the game over mode is set in S2 so that the game over (stopping) function is set. Note that the selection of whether or not to stop may be set by a dedicated switch. Next, in S4, it is determined whether or not the key switch is ON. When the key switch 43 is ON, the probability setting mode is set. When the key switch 43 is OFF, the game mode is set. When the key switch is OFF, the process proceeds to S5, and the RAM is normal. A determination is made as to whether or not the slot machine is normal. That is, since the RAM 48 shown in FIG. 4 is backed up by the backup power supply 63 at the time of a power failure or the like, it is executed at the time of power supply fall such as the time of power failure in steps S33 to S200 described later. The RAM 48 stores the program steps, and if YES is determined in S5, the program control returns to the stored power-off step.

  On the other hand, in the case of a runaway program, NO is determined in S5 and the process proceeds to S6, where the RAM is initialized and the set value of the winning probability is initialized. The winning probability is initialized by S6 so as to be set to “3”, for example. As will be described later, six setting values are prepared from “1”, which is the lowest probability, to “6”, which is the highest probability. It is initialized to a certain “3”. As a result, when the slot machine is initialized due to program runaway, etc., it is set to an average probability, so the winning probability is extremely high at the initialization caused by program runaway etc. There is an advantage that it is possible to prevent an extreme change such as switching to, or switching to an extremely low set value.

  On the other hand, when the key switch 43 is ON, that is, when the probability setting mode is operated, the process proceeds to S7, and the inserted coin channel is switched to the return side and the inserted coin is controlled to be returned. Next, the process proceeds to S8, where it is determined whether or not a start operation has been performed. In S10, it is determined whether or not the door switch has been operated. If not, the set value of the current probability is displayed on the payout number display 27, for example, in S13, and the process returns to S8. A dedicated set value display may be provided.

  If the game hall manager or a staff member operates the door switch 44 (see FIG. 1) once during the tour of S8 to S13, YES is determined in S10, and the process proceeds to S11. 1 ”is advanced. Next, proceeding to S12A, it is determined whether or not the current set value is “7”. Since the upper limit of the probability setting value is set to “6”, when the setting value becomes “7”, the process proceeds to S12B, and the process of setting the setting value to “1” again is performed and the process proceeds to S13. move on. On the other hand, if the set value is not “7”, the process proceeds directly to S13, where the current set value is displayed. The attendant at the amusement hall operates the door switch 44 so as to obtain a desired set value while viewing the display of the set value of the probability in S13. If the desired set value is reached, the key switch 43 is switched off to switch to the game mode, and then the start lever 13 (see FIG. 1) is operated to turn on the start switch 13, thereby determining YES in S8. Is made. As a result, since the key switch 43 has already been switched off, the process proceeds to S14, where the RAM is initialized, the probability setting value is determined, and the setting display is cleared. Next, through S14A, the cumulative number of coins inserted and the cumulative number of coins paid out are set to “100” and “50”, respectively, as initial values. As a result, the standard payout rate for the small role in the normal game is 50/100 × 100% = 50%. Next, the game start process is started.

FIG. 6B is a flowchart showing an interrupt program for random counter update processing. The interrupt program shown in FIG. 6B is executed based on the pulse signal periodically input from the pulse frequency dividing circuit 53 described above, and is executed once every 4 msec, for example. First, at S15, a process of updating the random counter value R by a predetermined number N is performed. Next, the process proceeds to S16, where it is determined whether or not the value R of the random counter has exceeded a predetermined maximum value. If it has not yet exceeded the maximum value, the process proceeds to S18 and one game has been completed. A determination is made whether or not. The one game is displayed when the variable display device is stopped. When no coins are paid out, the game ends when the variable display device stops. When coins are paid out, one game is completed at the stage where coins are paid out. Ends. If one game has not ended, the interrupt program ends and the next interrupt is awaited.

  On the other hand, if the value R of the random counter is greater than or equal to the maximum value, the process proceeds to S17, and after the process of subtracting and updating the value R of the random counter by the maximum value, the process proceeds to S18. Next, when the interrupt program of this time is executed at the timing when one game ends, the determination of YES is made in S18 and the process proceeds to S19, and the value N to be added and updated in S15 is changed based on the value R of the random counter. Processing is performed. This addition number N is selected from prime numbers of a plurality of types of prime numbers set in advance and the quotient when the maximum value is divided by the prime number is not an integer, and is changed in S19. By setting the addition number N in this way, the value R of the random counter is in a state where all numerical values can be taken uniformly. Further, every time one game is completed, the addition number N is changed to another prime number by S19, so that the value R of the random counter becomes a random value, and whether or not the winning is described later based on the value of this random counter. There is an advantage that a random decision can be made when making a decision.

  FIG. 7A is a flowchart of an interrupt program showing error check processing. First, in S20A, it is determined whether or not the card processing device 76 is connected. If no card processor connection signal is input, the process proceeds to S20B, and an error code “CC” indicating an error to that effect is displayed on the payout display 27. Is displayed. If the card processing device 76 is connected, the process proceeds to S20C, where it is determined whether or not the coin to be paid out is in a coin-out state. If it is determined that the coin is not out, the process proceeds to S21 to determine whether or not the inserted coin is jammed. If the inserted coins are not jammed, the process proceeds to S22, where it is determined whether or not the inserted coins are full in the surplus coin storage tank 41 (see FIG. 2). In step S24, it is determined whether or not a coin to be paid out from the coin hopper 37 (see FIG. 2) is jammed. If so, the interrupt program ends.

Then, the number of coins to be paid out has not reached the scheduled payout number that is the number of coins to be paid out as a result of the end of one game, and the coin payout motor 38 is rotating for a certain period of time. If coin payout is not detected, it is determined that the coin has run out and YES is determined in S20C, and the error code “HE” is displayed on the payout number display 27 (see FIG. 1) in S25. On the other hand, if the inserted coins are clogged in the coin take-in path 35 and the inserted coin sensor 36 (see FIG. 2) is in a state of continuously detecting coins for a predetermined time or longer, YES is determined in S22. A determination is made and an error code “CE” is displayed in S26. If the inserted coins are full in the surplus coin storage tank 41 and the full sensor 42 (see FIG. 2) detects that the full coins are full, a determination of YES is made in S22 and the process proceeds to S27, and the error code “CO” is the number of payouts. Displayed on the display 27. When the coins to be paid out from the coin hopper 37 are jammed and the payout coin sensor 39 (see FIG. 2) detects coins continuously for a predetermined time or more, a determination of YES is made in S23 and the process proceeds to S28. The error code “HJ” is displayed on the payout number display 27. If a motor error has occurred as a result of the determination in S85H, which will be described later, a determination of YES is made in S23A, the process proceeds to S28A, and the error code “EE” is displayed on the payout number display 27. Further, after determining that there is an error in S20 to S23, S described later.
During the period until the error code is cleared by 32, a determination of YES is made in S24 and the process proceeds to S29, and the display of the error code displayed in any of S25 to S28A is continued. In other words, the error code displayed in S29 is displayed until the error code is cleared in S32 to be described later after the front frame 1B in the opened state is closed even after the cause of the error is removed by the game staff. The error code display continues.

  After the processing of S25, S26, S27, S28, S28A or S29 is performed, the process proceeds to S30, where the game of the slot machine is interrupted and an error sound is generated from the speaker 28.

  If the attendant at the game hall hears that an error sound is emitted from the speaker 28, the attendant at the playground opens the front frame 1B in order to remove the cause of the error of the slot machine, and further displays the number of payouts. The type of the error cause that has occurred is identified from the error code displayed by 27, and the error cause that has occurred is removed by performing work according to the type of error cause. Then, after the work is completed, the attendant at the game hall closes the front frame 1B. Then, the door switch 44 detects that the front frame 1B is closed, and accordingly, YES is determined in S31. As a result, the control proceeds to S32, the error code displayed by the payout amount display 27 is cleared, the error sound is stopped, and the game is resumed from the game state at the time of occurrence of the interruption. Instead of actually closing the front member 1B, the detection output may be derived from the door switch 44 by pressing the door switch 44 with a finger or the like, and YES may be determined in S31.

  FIG. 7B and FIG. 8 are flowcharts showing the game start process. In S33, the flow path switching solenoid 33 (see FIG. 2) is controlled to switch the flow path of inserted coins to the take-in side, and the process proceeds to S34 to determine whether or not a game switching operation has been performed. If there is no game switching operation, the process proceeds to S40, but if the player presses the game switching button 16, the process proceeds to S35, where it is determined whether or not the credit game mode is currently set. If not, processing for setting the credit game mode is performed in S36. On the other hand, if it is already in the credit game mode, the process proceeds to S37, a process for setting the coin game mode is performed, and the process proceeds to S38, in which it is determined whether or not the credit counter is “0”. This credit counter is for counting and storing the number of coins awarded as prizes in the credit game and the number of coins inserted by the player, and “1” by S60 and S179 described later. In addition to the addition update, subtraction update is performed by “1” by S39 and S56 described later. If this credit counter is "0", the process proceeds to S40, but if it is "1" or more, the process proceeds to S39, where one coin is paid out and the credit counter is decremented by "1" and updated to S38. Return. The processing of S39 is repeated until the credit counter reaches “0”, and the coins corresponding to the count value of the credit counter are paid out. That is, when the player switches to the coin game mode while in the credit game mode, the player receives the number of coins corresponding to the value of the credit counter added and stored during the credit game. Therefore, the payout control is performed in S39. On the other hand, if the player presses the game switching button in the coin game mode at the present time, the process proceeds to S36 and the credit game mode is set.

Next, in S40, it is determined whether or not a start operation has been performed. If the start lever 12 (see FIG. 1) has not been pressed yet, the process proceeds to S41A. In S41A, it is determined whether or not there is a coin lending command signal. If not, the process proceeds to S41H. On the other hand, when the player presses the lending button 71, the operation signal is input from the lending switch 72 to the card processing device control unit 80, and a coin lending command is sent from the card processing device control unit 80 to the control unit 45 of the slot machine 1. A signal is input. Then, the control proceeds to S41B, and a coin lending signal is output from the control unit 45 to the card processing device control unit 80, and the lending number is set to “50”. On the other hand, the card processing device control unit 80 receives this coin lending signal, and deducts 1000 yen from the valuable value (remaining amount) owned by the player specified by the record information of the inserted common card. In this embodiment, the lending unit of coins is set to 1000 yen, but the lending unit is set to 100 yen, and every time 5 coins are paid out, the amount is reduced by 100 yen. The coins may be lent out. In this way, even if the remaining amount of the common card has a fraction of less than 1000 yen, the remaining amount can be lent out.

  Next, the process proceeds to S41C, where it is determined whether or not the credit game mode is set. If the credit game mode is not set, a control of paying out one coin is performed and the number of loans is set to “1” in S41F. Is subtracted and the process proceeds to S41G. On the other hand, if the player presses the credit operation button 14 to switch the slot machine 1 to the above-described credit game state, a YES determination is made in S41C, the process proceeds to S41D, and the credit counter becomes “50”. A determination is made whether or not. The credit counter is for counting the valuable value (the number of coins, etc.) owned by the player in advance for playing the credit game, and is incremented by “1” by S41D and S60 described later. Is subtracted by "1". If the credit counter is “50” which is the upper limit value, it is not possible to store the valuable value owned by the player in the credit counter any more. Therefore, the process proceeds to S41F, and one coin payout control is performed. It is. On the other hand, if the credit counter does not reach the upper limit “50”, the process proceeds to S41E, where “1” is added to the credit counter and the number of loans is subtracted from “1”.

  In S41G, it is determined whether or not the number of loans is “0”. If it is not “0”, the process returns to S41C to perform coin payout or credit counter addition processing again. By repeating this process, if the number of loans becomes “0”, the process proceeds to S41H.

Next, in S41H, it is determined whether or not the insertion number counter is “3”. The insertion number counter is used to count the number of coins inserted by the player through the coin insertion slot 18 when one game is played or the number of times the player has pressed the credit operation button 14 during the credit game. This is for setting the number of bets to bet on the game result, and is incremented and updated by “1” in S57, which will be described later, and is cleared in connection with S33 at the start of the next game, although not shown. The number of bets is input and set according to the count value of the inserted number counter, and when the number of bets, that is, the count value of the inserted number counter is “1”, one effective line (winning line) is set. When the count value is “2”, the number is set to three, and when the count value is “3”, the number is set to five. The upper limit of the count value of the insertion number counter is set to “3.” If the count value of the insertion number counter is not “3” which is the upper limit in S41, the process proceeds to S42 and the bonus game flag is set. A determination is made as to whether it is set. The bonus game flag is set in S162 and S169 when the bonus game (regular bonus game) is actually started based on the display result when the variable display device is stopped, and the bonus game is ended. In this case, it is cleared by S188. If the bonus game flag is not set, the process proceeds to S47. If the bonus game flag is set, the process proceeds to S43, where it is determined whether the insertion number counter is “0”. In the case of, the process proceeds to S47, and in the case of “1” or more, the process proceeds to S44. In other words, in the case of a bonus game, as described above, since only one effective line of the combination of the variable display devices is effective, only one-game betting is permitted. For this reason, the insertion number counter is “1”. It is controlled so as not to exceed the value. In S44, it is determined whether or not the credit game mode is set. If the credit game mode is not set, the process proceeds to S46, where the inserted coin channel is switched to the return side and the inserted coins are returned. After the process is performed, the process proceeds to S40. On the other hand, if the credit game mode is set, the process proceeds to S45, where it is determined whether or not the credit counter has already reached its upper limit value “50”. Since the credit counter cannot be updated any further, the process proceeds to S46, and the inserted coins are returned.

  In S47, it is determined whether or not a coin has been inserted. If so, the process proceeds to S48, where it is determined whether or not the insertion number counter has already reached its upper limit “3”. If “3”, the process proceeds to S60, a process of adding “1” to the credit counter is performed, and the process returns to S40. On the other hand, if the insertion number counter is not “3”, the process proceeds to S49, where it is determined whether or not the bonus game flag is set. If the bonus game flag is not set, the process proceeds to S57. Since the count value of the input number counter still has room, a process of adding “1” to the count value is performed. When the bonus game flag is set, the process proceeds to S50, and it is determined whether or not the insertion number counter is “0”. In the case of a bonus game, since the upper limit value of the insertion number counter is “1” as described above, if the insertion number counter is “1”, the process proceeds to S60 and the number of coins inserted into the credit counter. The process of adding “1” is performed. Next, the processing proceeds to S58, and processing for calling and storing the value R of the random counter that has been added and updated in accordance with the random counter updating processing described above is performed. The random value R may be stored when it is determined in S40 that the start operation has been performed. Next, the process proceeds to S59A, a process of setting the number of payouts and the number of payouts to “0” is performed, and the process proceeds to S59B. The planned payout is the number of coins to be paid out to the player according to the type of winning when winning is determined based on the display result when the variable display device is stopped. This is the number of coins actually paid out based on the winning.

  In S59B, it is determined whether or not the insertion number counter is “0”. If “0”, the process proceeds to S59C, and the effective line corresponding to the number of coins inserted in the previous one game is determined. Is turned on and the process returns to S40. On the other hand, if a coin has been inserted at the time of one game of this time, the inserted number counter is not “0”, so the process proceeds to S59D, an effective line is displayed according to the inserted number counter, and the process returns to S40. This effective line is displayed when the value of the input number counter is “1”, and only the effective line display lamp 21 displaying the central horizontal row is lit, and when the input number counter is “2”. The effective line display lamps 21 and 22 displayed by the horizontal three rows of effective lines are turned on, and when the input number counter is “3”, five effective lines of two rows are displayed on the horizontal three rows and diagonal lines. All the effective line display lamps 21 to 23 are lit up.

Next, if it is determined in S47 that no coin has been inserted, the process proceeds to S51, where it is determined whether or not the credit counter is “0”. It is determined whether or not there is an operation, and if there is no credit operation, the process proceeds to S59B. On the other hand, if the credit counter is “0”, the process proceeds directly to S59B without making a determination in S52. This is because, when the credit counter is “0”, no matter how much the player performs the credit operation by pressing the credit operation button 14, the game using the count value of the credit counter can be performed. This is because it is not possible to determine whether or not a credit operation has been performed. Next, if there is a credit operation, the process proceeds to S53, where it is determined whether or not the insertion number counter is “3”. If it is already “3” which is the upper limit value, the credit is counted. Ignore the operation and proceed to S59B. On the other hand, if it is not "3", the process proceeds to S54, where it is determined whether or not the bonus game flag is set. If the bonus game flag is set, the process proceeds to S55 and the insertion number counter Is determined to be “0”, and when the insertion number counter is “1” which is the upper limit value in the bonus game, the credit operation is ignored and the process proceeds to S59B. On the other hand, if the insertion number counter is “0” or if the bonus game flag is not set, the process proceeds to S56, and after updating the credit counter by “1”, the process proceeds to S57 and “1” is added to the insertion number counter. Processing is performed.

  As described above, the random value R of the random counter is read out in S58 every time the player inserts a coin from the coin insertion slot 18 so as to input and set the number of bets on the game result in one game. When the player inserts only one coin into the coin insertion slot 18 and starts one game, the random value R read based on the one inserted coin is stored and the random value is stored. R is used to predetermine the value-added contents when the variable display device is variably stopped. On the other hand, if the player inserts two coins from the coin insertion slot 18, the random value R read based on the insertion of the first coin is erased and read based on the insertion of the second coin. The updated random value R is stored, and the updated random value R is stored. Then, if the player performs a start operation, the value-added contents at the time of variable stop of the variable display device are determined in advance using the stored random value R. Further, if the player inserts three coins from the coin insertion slot 18, the random value R read based on the insertion of the first coin is read out based on the insertion of the second coin. The updated random value R is updated to a random value R read based on the insertion of the third coin, and the finally updated random value R is stored and variable. It is used for pre-determining the contents of value assignment when the display device is variably stopped. The random value R may be extracted by a start operation. On the other hand, every time the player depresses the credit operation button 14 to set and input the bet amount in the credit game, the random value R of the random counter is read and stored in S58 up to three times. The random value R is stored in the same manner as described above, if the random value R is read twice, the random value R read the first time is updated to the random value R read the second time, and stored. If the random value R is read three times, the random value R read the second time is updated to the random value R read the third time, and the last random value R is stored.

  Next, if the player presses the start lever 12, a determination of YES is made in S40, and the process proceeds to S61, in which it is determined whether or not the insertion number counter is “0”. The process proceeds to S41, but if it is “1” or more, the process proceeds to S62, the flow path switching solenoid 33 is controlled to switch the inserted coin flow path to the return side, and the subsequent reel rotation control is performed. As a result of the process of S62, coins inserted thereafter are returned to the coin storage tray 30.

  9 and 12 are flowcharts showing a reel rotation processing program. First, it is determined from S63 whether or not one game timer has expired. The one-game timer is used for measuring the time (for example, 4.1 seconds) that must pass from the start to the end of one game, and is set in S65. Note that the time set for one game timer may be changed according to the number of bets, and if the number of bets is one bet or two bets, a shorter time may be set than in the case of three bets. . If the 1-game timer has not expired, the process proceeds to S64, where a timer end waiting sound is generated from the speaker 28 to notify the player that the 1-game timer has not expired. On the other hand, if the 1-game timer is completed, the process proceeds to S65, where a 1-game timer is newly set, an operation invalid timer is set, and rotation of all reels is started. As described above, the operation invalid timer is a timer for measuring the time for invalidating the operation even if the stop buttons 9L, 9C, 9R are operated.

Next, the processing proceeds to S66, and processing for performing a predetermined calculation using the stored random value R is performed. The predetermined calculation means adding, subtracting, multiplying, or dividing the random value R, squaring or dividing the random value R, or substituting the random value R into a predetermined function. And calculating the answer. Next, the process proceeds to S67, and a process of comparing the calculation result with the winning allowable value according to the number of insertions, the set value, the probability variation counter, and the small combination determination mode is performed.

  For example, as shown in FIGS. 10 (c), (d) and FIG. 11, the winning allowances include big bonus game (BB) winning allowances, regular bonus game (RB) winning allowances, and re-game winnings. It consists of four types: allowable value and small role winning allowable value. Each winning allowance value is stored in the ROM 47 in the form of a table. The winning allowance shown in FIG. 10 (c) shows a case where the small winning combination determination mode is “normal”, the probability variation counter is “0”, and the probability setting value is “4” with three bets. This small role determination mode is set to “normal time” when the value giving situation to the player by the slot machine 1 is higher than the standard value, and is set to “normal time”. When it is low, it is set to “when the probability is high”, and is used for feedback control of the occurrence of the small combination according to the standard value. Further, at the time of “big bonus”, control is performed so that a small combination is generated with high probability. The probability variation counter is for storing how many times the occurrence probability of the big bonus game is improved, and becomes “2” by S195N described later, and becomes “1” by S195P. When the probability is not improved, “0” is stored. The “probability setting value” is a value set according to the operation of the key switch described above (see S9 to S13).

As shown in FIG. 10 (c), when the calculated value in S66 is less than the big bonus winning allowable value b ₀ , it corresponds to the big bonus game winning, and is equal to or more than b _{0 and} less than the regular bonus game winning allowable value b ₁ . If corresponds to the regular bonus game is to, in the case of a re-game winning less than the allowable value b ₂ in b ₁ or more corresponds to the re-game winning, b ₂ more than 15 pieces of small win winning permissible value b ₃
The fall in small combination winning be paid 15 coins if, in the case of 8 pieces of Small Win winning than the permissible value b ₄ in b ₃ above may correspond to small combination winning be paid 8 coins below, b If _four or more six small win winning than the permissible value b ₅ may correspond to a small win prize be paid 6 coins, in the case of less than winning tolerance b ₆ 3 pieces of small win with b ₅ or more coins It corresponds to the small role winning that pays out 3 cards, and it falls out of the case of b ₆ or more. Note that A ₃₄ , B ₃₄ , C ₃₁ , D ₃₁ , E ₃₁ , F ₃₁ , and G ₁₁ shown in FIG. 10 (c) are the values shown in FIGS. 10 (a) and 10 (b). R _MAX is an upper limit value that can be taken by a calculation result using the random value R.

  The numbers 1 to 6 shown in the leftmost column of FIG. 10A indicate probability setting values, and the numbers 1, 2, and 3 shown in the top row indicate the number of inserted coins, The number of bets is shown, BB is a big bonus game, and RB is a regular bonus game. Further, “normal time” indicates a case where the occurrence probability of the big bonus game is in a normal state, and “when changed” indicates a case where the occurrence probability of the big bonus game is improved. 1, 2 and 3 shown in the top row of FIG. 10B indicate the number of coins inserted, that is, the number of bets, and “normal”, “high probability” and “BB” shown in the lower row. "" Indicates whether the small role determination mode is normal, high probability, or big bonus.

In the case of FIG. 10 (c), it is a case where three bets are made, the small role determination mode is normal, the value of the probability variation counter is “0”, and the probability setting is “4”. numbers set-up number "4" is "3" in the probability of occurrence of big bonus game is described in the column corresponding to "normal" in (a), i.e., the a ₃₄ as big bonus game winning tolerance, B ₃₄ is used as the regular bonus game winning tolerance. In FIG. 10 (b), C ₃₁ , 8 is a numerical value described in the column when the number of insertions is “3” and the small combination determination mode is normal, that is, a small combination winning allowable value for paying out 15 coins. D ₃₁ as a small role winning allowance for paying out coins, E ₃₁ as a small role winning allowable value for paying out 6 coins, F ₃₁ as a small role winning allowable value for paying out 3 coins, and re-game winning G ₁₁ is used as an allowable value. The data shown in FIGS. 10A and 10B are stored in the ROM 47 in the form of a table.

FIG. 10D shows a case where three bets are made, the small role determination mode is “when high probability”, the value of the probability variation counter is “0”, and the probability setting value is “4”. In this case, according to FIGS. 10A and 10B, the big bonus game winning allowable value b ₀ = A ₃₄ , the regular bonus game winning allowable value b ₁ = b ₀ + B ₃₄ , and the re-game winning allowable value b ₂ = b ₁ + G ₁₁ , small combination winning allowance for paying 15 coins b ₃ = b ₂ + C ₃₂ , small winning combination allowance for paying 8 coins b ₄ = b ₃ + D ₃₂ , paying 6 coins The small combination winning allowable value b ₅ = b ₄ + E _{32 to be} issued and the small combination winning allowable value b ₆ = b ₅ + F ₃₂ for paying out three coins are obtained.

FIG. 11A shows a case where three bets, the small combination determination mode is “normal”, the value of the probability variation counter is other than “0”, and the probability setting value is “4”. In this case, according to FIGS. 10A and 10B, the big bonus game winning allowable value b ₀ = A ₄₄ , the regular bonus game winning allowable value b ₁ = b ₀ + B ₃₄ , and the re-game winning allowable value b ₂ = b ₁ + G ₁₁ , small combination winning allowance for paying 15 coins b ₃ = b ₂ + C ₃₁ , small winning combination allowance for paying 8 coins b ₄ = b ₃ + D ₃₁ , paying 6 coins The small combination winning allowable value b ₅ = b ₄ + E _{31 to be} issued and the small combination winning allowable value b ₆ = b ₅ + F ₃₁ for paying out three coins are obtained.

  FIG. 11 (b) shows a case where three bets are made, the small role determination mode is “high probability”, the value of the probability variation counter is other than “0”, and the probability setting value is “4”. In accordance with the tables of FIGS. 10A and 10B, each winning allowable value is determined as shown in FIG. 11B. FIG. 11C shows a case where three bets are made, the small role determination mode is “high probability”, and the big bonus game winning flag is being set or the regular bonus game winning flag is being set. In this case, there is no big bonus game winning tolerance and regular bonus winning tolerance. FIG. 11D shows a case where three bets are made and the small combination determination mode is “when big bonus”. In this case, there is no big bonus winning allowable value and no re-game winning allowable value. In this case, as the bonus game winning allowable value, the numerical value in the bottom row of FIG. 10B is used.

  By configuring as described above, the small role occurrence probability is higher when the small role determination mode is “high probability” than “normal time”, and the small role determination mode is “when big bonus”. In this case, the probability of occurrence of a small combination is further increased and the probability of occurrence of a bonus game is also increased. Also, the probability of occurrence of a big bonus game, the probability of occurrence of a bonus game, the probability of occurrence of a small role, and the probability of occurrence of a re-game are higher in the case of two bets than two bets and three bets than two bets. In addition, the probability of occurrence of a big bonus game is higher when the value of the probability variation counter is other than “0” than when it is “0”. As shown in FIG. 10A, in this embodiment, when the value of the probability variation counter is not “0” and the big bonus game occurrence probability is improved, the number of inserted coins is three. Limited to 3 bets. By setting the data shown in FIGS. 10 (a) and 10 (b) to appropriate values, the small payout rate, that is, (Each small win winning probability × coin payout number) / coin inserted number × 100% is appropriately set. Can be a value. For example, 50% is set when the small role determination mode is “normal time”, 100% when “high probability”, 150% when “big bonus”, and the like.

  Next, in S68, it is determined whether or not the bonus game flag is set. If the bonus game flag is not set, the process proceeds to S71 and it is determined whether or not the big bonus game flag is set. If the big bonus game flag is not set, the process proceeds to S74. In S74, a reel rotation sound is generated from the speaker 28, and then the process proceeds to S75, in which it is determined whether or not the big bonus winning flag or the bonus winning flag is set. Proceed, but if not set, proceed to S76.

In S76, it is determined whether or not the comparison result in S67 and the calculation result using the random value R are included in the big bonus winning allowable value, that is, whether or not 0 ≦ calculation result <b _0. If YES, the process proceeds to S77, the big bonus winning flag is set, and the process proceeds to S80. On the other hand, if the comparison result in S67 shows that the calculation result using the random value R is not the big bonus winning allowable value but is included in the bonus winning allowable value (b ₀ ≦ calculating result <b ₁ ), the process returns to S78. A determination of YES is made and the process proceeds to S79, the bonus winning flag is set, and the process proceeds to S80. In S80, processing for starting lighting of the game effect lamp 24 (see FIG. 1) is performed, and then the process proceeds to S85. By the process of S80, a notification that a big bonus or bonus has been won is given. Instead of lighting the game effect lamp 24 in S80, a dedicated display may be provided to notify that a big bonus winning or a bonus winning has occurred, and a predetermined sound is generated from the speaker 28. You may make it alert | report. As a result of the processing of S80, the player recognizes that the player has won the big bonus or has won the bonus. As will be described later, even if the player reaches the reach state during the stop control of the variable display state, Since no reach sound is generated unless a bonus is won (S108 to S110), the player is notified of the reach state even though there is no possibility of becoming a big bonus game or a bonus game. Get rid of discomfort.

If NO is determined in S78, the process proceeds to S81, and it is determined whether or not the comparison result in S67 and the calculation result using the random value R are included in the re-game winning allowable value. However, if it is included (b ₁ ≦ calculation result <b ₂ ), the process proceeds to S 82, the re-game winning flag is set, and the process proceeds to S 85. By setting the re-game winning flag in S82, as will be described later, the variable display device is automatically variably started by the start operation without inserting coins, and re-game is controlled. In S83, it is determined whether or not the comparison result of S67 and the calculation result using the random value R are included in each small part winning allowable value. If not included, the process proceeds to S85 as it is. (B ₂ ≦ calculation result <b ₃ , b ₄ , b ₅ , b ₆ ), the process proceeds to S84, and a winning flag corresponding to the type of the included small role is set, and the process proceeds to S85.

  Next, when the bonus game flag is set, a determination of YES is made in S68 and the process proceeds to S69, and whether or not the comparison result of S67 and the calculation result of the random value R are included in the allowable JAC winning value. Judgment is made. In other words, the determination of YES in S68 means that the game state of the slot machine is a bonus game, and the display result when the variable display device during variable stop during the bonus game is “JAC” is a stop pattern. In this case, as described above, winning in the bonus game occurs and 15 coins can be paid out. In S69, it is determined whether or not winning is generated in the bonus game. It is. Then, if NO is determined in S69, the process proceeds to S85 as it is, but if YES is determined, the process proceeds to S70, and the JAC winning flag is set. As a result, as will be described later, control for generating a winning in the bonus game is performed.

On the other hand, if the big bonus game flag is set instead of the bonus game flag, a determination of YES is made in S71 and the process proceeds to S72. The comparison result in S67 and the calculation result using the random value R become the bonus game allowable value. A determination is made as to whether it is included. When the slot machine game state is a big bonus and the display result at the time of variable stop of the variable display device is a combination of stop symbols of “JAC”, the bonus game in the big bonus game starts as described above. Therefore, in S72, it is determined whether or not to generate a bonus game in the big bonus game. If NO is determined in S72, the process proceeds to S83. If YES is determined, the process proceeds to S73, the JAC winning flag is set, and the process proceeds to S85.

  Next, in S85, it is determined whether or not the operation invalidation timer has expired, and the process waits until it is completed. The time set in this operation invalid timer is a time (for example, 1 second) longer than the time necessary for performing the processing of S68 to S84. If the operation invalidation timer has expired, the process proceeds to S86, where a reel stop timer is set, and control to turn on the operation valid lamps 11L, 11C, 11R (see FIG. 1) is performed.

  Next, in S85A, it is determined whether or not the left reel reference position has been detected. If not, the process proceeds to S85C, and it is determined whether or not the middle reel reference position has been detected. The process proceeds to S85E to determine whether or not the right reel reference position has been detected. If not, the process proceeds to S85G to determine whether or not the left, middle, and right reference position detection flags are set. If not, the process proceeds to S85H, where it is determined whether or not the operation invalidation timer has ended. If not, the process returns to S85A. If the left reel reference position 6La is detected by the left reel position sensor 8L during the loop of S85A to S85H, the process proceeds to S85B, and the left reference position detection flag is set. If the middle reel reference position 6Ca is detected by the middle reel position sensor 8C, the process proceeds to S85D, and the middle reference position detection flag is set. If the right reel reference position 6Ra is detected by the right reel position sensor 8R, the process proceeds to S85F, and the right reference position detection flag is set. If all the left, middle, and right reference position detection flags are set, a determination of YES is made in S85G, and the process proceeds to S85I. On the other hand, if the operation invalid timer set in S65 has expired without detecting the left, middle and right reel reference positions, the reel is not rotated or the reel position sensor is broken. As a result, a motor error occurs and the operation proceeds when an error occurs.

In S85I, the process waits until the operation invalidation timer ends. When the operation invalidation timer ends, the process proceeds to S86, and the reel stop operation is validated. As described above, the stop operation is validated after the operation invalidation timer expires after the reference position of each reel is detected. Instead of S85I, as in S85J, it may be determined whether or not the number of feed steps of the stepping motor that rotates the reel has reached a predetermined value. In S86, a reel stop timer is set, and control to turn on the operation effective lamps 11L, 11C, 11R (see FIG. 1) is performed. The reel stop timer is a timer for automatically stopping the reel by counting a predetermined time when the player does not operate the stop buttons 9L to 9R at all. Next, the process proceeds to S87, in which it is determined whether or not all the reels have been stopped. If not yet stopped, the process proceeds to S88, in which it is determined whether or not the reel stop timer has expired. If it is determined that the reel stop timer has expired, the process proceeds to S95, the left, middle and right reel stop flags are set, and the process proceeds to S96. On the other hand, if the reel stop timer has not expired, the process proceeds to S89, in which it is determined whether or not there has been a left reel stop operation. In this case, it is determined whether or not a right reel stop operation has been performed in S93. If not, the process proceeds to S96. On the other hand, if the player presses the left stop button 9L, a determination of YES is made in S89, the process proceeds to S90, the left reel stop flag is set, and the left reel is controlled to stop. Next, when the player presses the middle stop button 9C, a determination of YES is made in S91 and the process proceeds to S92, where the middle reel stop flag is set and the middle reel is controlled to stop. If the player presses the right stop button 9R, a determination of YES is made in S93, the process proceeds to S94, the right reel stop flag is set, and the right reel is controlled to stop. Next, a case where the player presses two or more stop buttons 9L, 9C, and 9R at the same time will be described. For example, when the player simultaneously presses the left stop button 9L and the middle stop button 9C, first, a determination of YES is made in S89, the process proceeds to S90, the left stop flag is set, and the left reel is inserted as described later. The stop control is performed and YES is determined in S91, and the process proceeds to S92. The intermediate reel stop flag is set, and the middle reel is controlled to be stopped as described later. Thus, even if the player presses a plurality of stop buttons at the same time, the reel corresponding to the pressed stop button is controlled to stop, and the stop operation of one of the buttons is invalidated. There is no inconvenience. The same applies to the case where three stop buttons 9L, 9C, and 9L are pressed simultaneously.

  Next, it is determined whether or not the left reel stop flag is set in S96. If it is not set, it is determined whether or not the middle reel stop flag is set in S100. In S104, it is determined whether or not the right reel stop flag is set. If it is not set, the process proceeds to S108. If the left reel stop flag is set, the process proceeds to S97 to determine whether or not the left reel is rotating. If the left reel is rotating, the reel stop control is performed in S98 and then the process proceeds to S99. Advance and the left reel stop flag is cleared. On the other hand, if the left reel has already stopped, NO is determined in S97 and the process proceeds directly to S99. Since the same processing as S96 to S99 described for the left reel is performed for the middle reel and the right reel, the description will not be repeated here. Next, when all reels are stopped, a determination of YES is made in S87, and the process proceeds to a winning determination process shown in FIG.

  On the other hand, if NO is determined in S104, the process proceeds to S108, and it is determined whether or not the symbols displayed by any two reels that are stopped are the symbols in the reach state. The reach state is a stage where any one of the plurality of variable display portions 5L, 5C, 5R is still variably displayed, and the display results of the variable display portions that have already stopped are “AAA”, “BBB”. It means a case where a predetermined display condition is satisfied that satisfies a combination of specific identification information such as “”. If it is determined in S108 that the reach state is not reached, the process proceeds to S87, but if it is determined that the reach state is determined, the process proceeds to S109 to determine whether the big bonus winning flag or the bonus winning flag is set. A determination is made and if none is set, the process proceeds to S87, but if any is set, the process proceeds to S110, and a reach sound is generated from the speaker 28, and then the process proceeds to S87. By generating this reach sound, the player's expectation that the combination of the specific identification information may be established depending on the display result when the variable display unit currently variably displayed by the player is stopped is effective. Can be excited. In addition to or instead of generating a reach sound from the speaker 28, an indication that a reach state has occurred may be displayed. Further, the notification at the time of reaching may be performed only when the big bonus winning flag is set, or the notification may be performed only at the time of reaching the one of which the winning flag is set.

13 to 15 are flowcharts showing the specific contents of the reel stop control defined by S98, S102, and S106. First, in S111, processing for confirming the current symbol number is performed. As described above, there are 21 symbol numbers from 0 to 20 (see FIG. 3). The number of feed steps of the reel drive motors (stepping motors) 7L, 7C and 7R and the reference position detection of the reel position sensors 8L, 8C and 8R are detected. Based on the signal. Next, in S112, it is determined whether or not the bonus game flag is set. If the bonus game flag is set, the process proceeds to S113, where it is determined whether the other two reels are stopped. The other two reels mean reels other than the reel for which stop control is currently being performed. Then, when the other two reels are not yet stopped, the process proceeds to S120, and control is performed to stop the JAC symbols within four symbols ahead of the current symbol number confirmed in S111 on the active effective line. The process proceeds to S152. In the case of a slot machine, in order to prevent the stop control from becoming unnatural, the player presses the stop buttons 9L, 9C, and 9R, and is limited to a very short time of about 0.2 seconds. The corresponding reel must be stopped within a predetermined time, and the rotation angle at which the reel can rotate within the very short predetermined time is about 4 symbols. Therefore, since it is impossible to stop control of a JAC symbol that is 4 or more symbols ahead on an effective effective line after the stop button is pressed, there is a JAC symbol within 4 symbols ahead in S120. The JAC symbol is controlled to stop on the active line. As shown in FIG. 3, when the current symbol number is not a JAC symbol, the symbol array is configured such that the JAC symbol always exists within the range of four symbols ahead of the current symbol number. As described above, when the reel to be stopped is not the last reel, the JAC symbol is controlled to be stopped on the active line that is valid regardless of whether or not the JAC winning flag is set. Yes, this will cause the player to keep an eye on the subsequent stop of the reel with expectation. Next, the process proceeds to S152, in which the operation effective lamp corresponding to the stopped reel among the operation effective lamps 11L, 11C, 11R is turned off and the reel stop sound is emitted from the speaker 28, and any of S99, S103 or S107 is performed. Return to crab.

  When the bonus game flag is set and the other two reels are stopped, the process proceeds to S104, it is determined whether or not the JAC winning flag is set, and only when the bonus game flag is set, the process proceeds to S120. If not set, the process proceeds to S115. In S115, the JAC symbol within 4 symbols ahead of the current symbol number is removed from the effective line and stopped, and then the process proceeds to S152. That is, since the JAC winning flag is not set, it is not possible to establish a combination of JAC symbols on the active line that is valid, and therefore the JAC symbol is forcibly shifted from the active line that is valid. And stop.

  Next, when the bonus game flag is not set, the process proceeds to S116, where it is determined whether or not the big bonus game flag is set. When the big bonus game flag is set, the process proceeds to S117. Then, it is determined whether or not the JAC winning flag is set. If the JAC winning flag is set, the process proceeds to S118, and it is determined whether or not the other reels are stopped. Then, when the other reels are not stopped, the process proceeds to S120, and control is performed to stop the JAC symbols on the valid lines that are valid as described above. On the other hand, if the other reels are already stopped, the process proceeds to S119, and the JAC symbols that are within 4 symbols ahead of the current symbol number are stopped on the JAC symbol active line of the reels that have been stopped. Stop control is performed so that a combination of JAC symbols is established on the active line, and then the process proceeds to S152.

  On the other hand, when the big bonus game flag is not set or when the JAC winning flag is not set, the process proceeds to S121, and it is determined whether or not the re-game winning flag is set. If the re-game winning flag is set, the process proceeds to S122, where it is determined whether or not other reels are stopped. If the other reels are not yet stopped, the process proceeds to S123 and the current symbol is displayed. Control is performed so that JAC symbols within 4 symbols ahead of the number are aligned and stopped on the active line of the stopped JAC symbols, and the process proceeds to S152. On the other hand, when the other reels are stopped, the process proceeds to S124, and control is performed to align and stop the JAC symbols within the 4 symbols ahead of the current symbol number on the active line of the stopped JAC symbols. Proceed to

On the other hand, if the re-game winning flag is not set, the process proceeds to S125, and it is determined whether or not the big bonus winning flag is set. If the big bonus winning flag is set, the process proceeds to S126, where it is determined whether or not the other reels are stopped. If the other reels are not yet stopped, the process proceeds to S127 and the current symbol is displayed. It is determined whether or not there is a big bonus symbol (A in this embodiment) within four symbols ahead of the number. If there is, the big bonus symbol is stopped on the active line in S128, and then S152.
Proceed to On the other hand, if there is no big bonus symbol within 4 symbols ahead of the current symbol number, the start of the big bonus game in that game is given up and the process proceeds to S139. Even when NO is determined in S127, since the big bonus winning flag remains set, the control for stopping the big bonus symbol on the active line again in the next game is performed. An attempt is made and repeated until the big bonus symbol actually stops on the active line.

  Next, if it is determined by S126 that the other reels are stopped, the process proceeds to S129, and it is determined whether or not there is a big bonus symbol on the active line. If there is, the process proceeds to S130 and stopped. It is determined whether or not there is a big bonus symbol that can be stopped on the active line of the big bonus symbol being within four symbols ahead of the current symbol number. If so, the process proceeds to S131 to stop the big bonus symbol. Control is performed to stop the reel on the effective line of the big bonus symbol of the reel. On the other hand, if it is determined by S130 that there is no big bonus symbol that can be stopped on the active line of the stopped big bonus symbol within four symbols ahead, the start of the big bonus game at that time is performed in the same manner as described above. After giving up and proceeding to S139, the stop control of the variable display device is attempted so that the big bonus game is started again in the next game.

  If the big bonus winning flag is not set, the process proceeds to S132 to determine whether or not the bonus winning flag is set. If the bonus winning flag is set, the process proceeds to S133 and other reels are determined. A determination is made whether or not is stopped. When the other reels are not stopped, the process proceeds to S134, and it is determined whether or not there is a bonus symbol (B in the present embodiment) within 4 symbols ahead of the current symbol number. Control for stopping the bonus symbol on the activated effective line is performed, and the process proceeds to S152. On the other hand, if it is determined in S134 that there is no bonus symbol, the process proceeds to S152. Next, if it is determined in S133 that the other reels have already stopped, the process proceeds to S136, and it is determined whether or not there is a bonus symbol on the active line. If not, the process proceeds to S139. On the other hand, if there is a bonus symbol on the active line, the process proceeds to S137, and it is determined whether or not the bonus symbol that can be stopped on the active line of the bonus symbol that is stopped is within four symbols ahead of the current symbol number. If not, the process proceeds to S139. If the process proceeds to S138, control is performed to stop the bonus symbol on the effective line of the bonus symbol of the reel that has stopped the bonus symbol, and the process proceeds to S152.

  On the other hand, if it is determined in S132 that the bonus winning flag is not set, the process proceeds to S139, in which it is determined whether or not the small role winning flag is set, and it is determined that the small role winning flag is set. If YES, the process proceeds to S140, where it is determined whether the other reels are stopped. If the other reels are not stopped yet, the process proceeds to S144. In S144, it is determined whether or not the small character symbol corresponding to the set small character winning flag type is within four symbols ahead of the current symbol number. If not, the process proceeds to S146 and the reels are stopped immediately. The process proceeds to S152. On the other hand, if it is determined in S144 that there is a small role symbol, the process proceeds to S145, control for stopping the small role symbol on the active line is performed, and the flow proceeds to S152. Next, in a stage where the other reels are stopped, a determination of YES is made in S140 and the process proceeds to S141, where it is determined whether or not there is a small role symbol on the active line, and if not, the process proceeds to S147. In this case, the process proceeds to S142, and it is determined whether or not there is a small role symbol that can be stopped on the active line of the stopped small character symbol within 4 symbols ahead of the current symbol number. If there is advancing, the process proceeds to S143, and after the control to stop the small role symbol on the active line of the small role symbol of the reel that has stopped, the flow proceeds to S152.

If it is determined in S139 that the small role winning flag is not set, the process proceeds to S147. In S147, it is determined whether or not the other two reels are stopped. If not yet stopped, the process proceeds to S149 to determine whether or not the reel that is currently stopped is the left reel. If it is not a reel, stop control is immediately performed in S150 and then the process proceeds to S152. If it is a left reel, the process proceeds to S151, and the single symbol F is controlled to stop on the active line and then the process proceeds to S152. In other words, if the single symbol F is stopped on the active line even though it is determined that the small role winning flag is not set by S139, the small symbol winning is established. It stops by forcibly shifting so as not to stop on the active line. Further, when the other two reels are already stopped, a determination of YES is made in S147, and the process proceeds to S148. After stopping control so that none of the symbols are aligned on the active line, the process proceeds to S152. As described above, when there is no winning, the reels that are stopped first and second are stopped almost instantaneously by detecting the stop operation of the player (S89, S91, S93). Therefore, in the case of a player who is excellent in the technique of operating the stop buttons 9L, 9C, 9R while aiming at the timing, it becomes possible to frequently stop the reels stopped first and second in the reach state. . If a reach sound is generated each time, it is noisy, but in this embodiment, as shown in S109, a reach sound is generated only when the big bonus and bonus winning flag is set. There are no inconveniences because it is generated. When the small role winning flag is set, processing for clearing the small role winning flag is performed at the end of one game (see S200). Therefore, in spite of the fact that the small role winning flag is set, it is not possible to align the small role symbols corresponding to the type of the small role winning flag on the active line due to the reel symbol arrangement in that game. In this case, the small role winning flag is cleared and the small role winning becomes invalid, and the small role winning flag is taken over to the next game and the small role winning symbols are aligned on the active line in the next game. There is no control.

  S63 to S152 constitute variable display control means for controlling the variable display device.

  FIG. 16 is a flowchart showing a program for winning determination processing. First, in S153, it is determined whether or not the bonus game flag is set. If it is not set, the process proceeds to S159 and it is determined whether or not the big bonus game flag is set. In this case, the process proceeds to S163, where it is determined whether or not there is a winning on the active line. If there is no winning on the active line, the process proceeds to S164, and after setting the number of payouts to “0”, the process proceeds to coin payout control shown in FIG. On the other hand, if it is determined in S163 that the winning line has been won, the process proceeds to S165, and the effective line display lamp corresponding to the winning effective line is blinked. When a winning occurs on a plurality of active lines, the effective line on which the winning occurs is blinked. Next, in S166, it is determined whether or not the winning is a big bonus winning. If it is determined that the prize is not a big bonus, the process proceeds to S168, and it is determined whether or not the prize is a bonus prize. If it is determined that the prize is not a bonus prize, it is determined whether or not the game is won again in S170. Judgment is made. If it is determined that the game is not a re-game winning in S170, the winning is a small winning combination, and thus the process proceeds to S175, the number of payouts is set to a value corresponding to the small winning combination, and then the process proceeds to the coin payout process shown in FIG. To do.

If it is determined that the big bonus is won in S166, the process proceeds to S167, where each small role winning determination value is set to the value for the big bonus, the big bonus game counter is set to “30”, and the bonus number counter is set to “3”. ”, Clear the big bonus winning flag, set the expected payout number to“ 15 ”, set the big bonus game flag, flash the game effect lamp in the first mode, and generate the big bonus sound from the speaker Processing is performed. Since each small role winning decision value is set to the value at the time of the big bonus, and the number of each small role winning decision value is controlled to be greatly increased, the probability of each small role winning decision is greatly improved, and the big bonus At the time of the game, control is performed so that the small role symbols are aligned with high probability. Note that, during the big bonus game, a predetermined set of a plurality of types of small role winning flags may be set for each game without particularly determining whether the small role is won. On the other hand, if it is determined in S168 that the bonus is won, the process proceeds to S169, the bonus game counter is set to “12”, the JAC winning counter is set to “8”, the bonus winning flag is cleared, and the payout is scheduled. The number is set to “15”, the bonus game flag is set, the game effect lamp blinks in the second mode, and the bonus sound is generated from the speaker.

  Next, if the bonus game flag is set, a YES determination is made in S153, and the process proceeds to S154, the bonus game counter is decremented by “1”, and the process proceeds to S155, where there is a JAC prize on the active line. If it is not determined, the number of payouts is set to “0” and the process proceeds to coin payout control. On the other hand, if there is a JAC winning on the active line, the process proceeds to S156, the scheduled payout number is set to “15”, the JAC winning counter is decremented by “1”, and the effective line corresponding to the winning active line is determined in S157. After blinking the display lamp, the process shifts to coin payout control.

  Next, when the big bonus game flag is set, a determination of YES is made in S159 and the process proceeds to S160, the big bonus game counter is decremented by “1”, and whether or not there is a JAC winning on the active line in S161. If not, the process proceeds to S163. If there is, the process proceeds to S162. In S162, the bonus game counter is set to “12”, the JAC winning counter is set to “8”, the bonus game flag is set, the scheduled payout number is set to “8”, and the game effect lamp is set to the second mode. Flashes to generate a bonus sound from the speaker. As described above, S169 is a process performed when a bonus game is started in a normal game that is not a big bonus game. In S162, a bonus game is established when the big bonus game is started. Processing to be performed.

  On the other hand, if it is determined that the game is won again in S170, the process proceeds to S171, where the random counter R (see FIG. 6) is stored, and the regame display lamp 64 is turned on or blinking in S172. Then, a re-game display is performed and a process for generating a re-game sound from the speaker 28 is performed. Next, in S173, it is determined whether or not a start operation has been performed, and the process waits until it is present. Then, when the player operates the start lever 12, the control proceeds to S174, and after the re-game winning flag is cleared, the process proceeds to the reel rotation process shown in FIG. As a result, since the reel rotation control is performed without executing the program shown in FIGS. 7 and 8, the bet number already input last time is carried over without accepting an additional input of the bet number. A re-game is performed.

In S175A, after the number of payouts is set to the small role corresponding value (15, 8, 6, or 3 in FIG. 11), the process proceeds to S175B to determine whether or not the bonus game flag is set and set. If yes, the process proceeds to the coin payout process shown in FIG. On the other hand, if it is not set, the process proceeds to S175C, where it is determined whether or not the big bonus game flag is set. If it is set, the process proceeds to coin payout control shown in S17. If the big bonus game flag is not set, the process proceeds to S175E. Note that S175D is a step inserted in the case of another embodiment to be described later. In S175E, processing is performed in which the value of the input number counter is added to the cumulative input number, and the value of the planned payout number is added to the cumulative payout number. Next, proceeding to S175F, a process of calculating the cumulative payout number / cumulative input number is performed, and a process of calculating the value assignment status by the slot machine 1 is performed.

Next, the process proceeds to S175G, and it is determined whether or not the small role determination mode is “high probability”. If not, the process proceeds to S175H, and the calculated value calculated in S175F is 0.4 (normal) In the case of less than 0.4, the small role determination mode is set to “at the time of high probability” in S175I, and then the process proceeds to S175L. On the other hand, if the calculated value is 0.4 or more, the process proceeds to S175L. As a result of the determination of S175G, when the small role determination mode is “high probability”, the process proceeds to S175J, and whether or not the calculated value calculated by S175F is 0.5 (upper limit value at high probability) or more. Judgment is made. If it is 0.5 or more, the process proceeds to S175K, and after setting the small combination determination mode to “normal time”, the process proceeds to S175L. On the other hand, if it is determined by S175J that the calculated value is less than 0.5, the process proceeds to S175L. In this way, when the small combination determination mode is normal, the small combination determination mode is updated to “when high probability” when the payout rate of the small combination divides 40%. Further, when the small combination payout rate reaches 50% when the small combination determination mode is “high probability”, the small combination determination mode is returned to “normal time”.

  Next, in S175L, it is determined whether or not the cumulative number of insertions is “300” or more. If not, the process proceeds to the coin payout control shown in FIG. 17 as it is, but if so, the process proceeds to S175M. After the processing of correcting the cumulative insertion number and the cumulative payout number to each ½ value (rounded up after the decimal point), the process proceeds to coin payout control. The processes in S175L and S175M are processes for preventing the cumulative input number and the cumulative payout number from becoming too large when the number of games increases.

  The calculation method of the coin payout status, that is, the value addition status, is not limited to the embodiment shown in S175F. For example, (cumulative input number−cumulative payout number) / game number may be calculated. Further, the cumulative number of payouts may be used instead of the cumulative payout number of coins, or may be calculated using both the cumulative payout number and the cumulative number of payouts. Furthermore, an addition / subtraction counter that adds according to the number of coins inserted and subtracts according to the number of coins paid out may be provided, and the value of the addition / subtraction counter may be used as a calculated value. In the present embodiment, only the probability of occurrence of a small combination is controlled by comparison with a standard value. Therefore, a random value R is used for occurrence of a big bonus or a regular bonus while keeping a payout rate in a normal game within a predetermined range. A game machine that is controlled by the extraction timing and the set value, and does not always have a large number of bonus occurrences even at high settings, and it is not necessarily low even at low settings, and can keep the game interesting for the player. It can be.

  In the embodiment shown in FIG. 16, when calculating the payout rate in S175F, it is calculated based on the number of coins inserted and the number of coin payouts in a normal game excluding the big bonus game and the regular bonus game. Instead, it may be calculated including the number of coins inserted and the number of coins paid out in the big bonus game and the regular bonus game. Further, the calculation of S175F and the determinations of S175H and S175J may be performed only when the cumulative number of coins inserted reaches a predetermined value.

Next, another embodiment in which the step of S175D is inserted will be described. In this alternative embodiment, in the normal game, the probability control of the small combination is performed only when three bets are placed, and the process proceeds to S175E only when the insertion number counter is “3” by S175D. The probability control of the combination is performed, and if the insertion number counter is not “3”, the process proceeds to the coin payout control as it is. In the case of this alternative embodiment, each small combination winning allowable value C ₁₂ , D ₁₂ , E ₁₂ , in the “high probability” column in the case of the coin insertion numbers “1” and “2” in FIG. F ₁₂ , C ₂₂ , D ₂₂ , E ₂₂ and F ₂₂ are not required. According to S175E through S175M, it is calculated by at least one of the cumulative value of the input number input by the betting number input means, the cumulative value of the valuable value given by the value granting means, and the cumulative value of the number of times the valuable value is given. Probability control means is configured to compare the value assignment situation with a predetermined standard value and control the probability that the display result of the variable display device will be in a specific display mode based on the comparison result.

  FIG. 17 is a flowchart showing a program for coin payout control. First, in S176, it is determined whether or not the number of payouts has reached the planned payout number. If not, the process proceeds to S177, in which it is determined whether or not the game mode is the credit game mode. Advances to S180, pays out one coin and advances the payout number by "1" accordingly, and returns to S176. On the other hand, if it is in the credit game mode, the process proceeds to S178, where it is determined whether or not the credit counter is “50” which is the upper limit value. If it is, the process proceeds to S180, where coins are paid out. If not, that is, if there is still a margin in the credit counter, the process proceeds to S179, the credit counter is incremented by "1", and the payout number is incremented by "1" accordingly, and then S176 is performed. Return to. The processing of S177 to S180 is repeatedly executed until the number of payouts = the planned payout number, and coin payout or addition processing to the credit counter is performed each time, and when the payout number reaches the payout number, S181 is executed. Proceed to

  In S181, it is determined whether or not the bonus game flag is set. If the bonus game flag is not set, the process proceeds to S182 to determine whether or not the big bonus game flag is set. If the bonus game flag is not set, the process proceeds to S200, where the JAC winning flag is cleared, the small role winning flag is cleared, the previous inserted number is updated to the value of the inserted number counter, and the inserted number counter is cleared. Returning to the game start process shown in FIG. On the other hand, if the bonus game flag is set, the process proceeds to S185, where it is determined whether or not the JAC winning counter has become “0”, and if so, the bonus game counter is cleared in S186. , S188, the JAC winning counter is cleared, and the bonus game flag is cleared. On the other hand, if the JAC winning counter is not “0”, the process proceeds to S187, where it is determined whether the bonus game counter is “0”. If it is “0”, the process proceeds to S188, but is not “0”. In this case, the process proceeds to S200, the JAC winning flag is cleared, the small role winning flag is cleared, and the process returns to the game start process shown in FIG. As described above, the bonus game flag is cleared when the bonus game counter becomes “0” or when the JAC winning counter becomes “0”, and the bonus game ends.

  Next, in S189, it is determined whether or not the big bonus game flag is set. If the big bonus game flag is not set, the game effect lamp 24 is turned off in S190, and the process proceeds to S200. On the other hand, if the big bonus game flag is set, the process proceeds to S191, where the bonus number counter is decremented by “1”, and whether or not the bonus number counter has become “0” is determined in S192. Made. When the bonus number counter is not “0”, the process proceeds to S193, where a process for causing the game effect lamp to blink in the first mode and generating a big bonus sound from the speaker 28 is performed, and the process proceeds to S200. On the other hand, if the bonus number counter is “0”, the process proceeds to S194, and after the big bonus game counter is cleared, the process proceeds to S195.

On the other hand, if the bonus game flag is not set and the big bonus game flag is set, the process proceeds to S183, where it is determined whether or not the big bonus game counter is “0”. If not, the process proceeds to S200, but if it is “0”, the process proceeds to S184, a process of clearing the bonus number counter is performed, and the process proceeds to S195A. In S195A, the big bonus game flag is cleared to end the big bonus game, the small role determination mode is set to “normal time”, the cumulative input number is set to “100”, the cumulative payout number is set to “50”, and the game effect Processing to turn off the lamp is performed. In other words, the big bonus game ends when the big bonus game counter reaches “0” or when the bonus count counter reaches “0”. Is controlled to return to the “normal time” and return the cumulative number of inputs and the cumulative number of payouts to the initial values (see S14A).

  Next, the process proceeds to S195B, where a process of storing the current random value R is performed, and a process of performing a predetermined calculation using the stored value is performed in S195C. This predetermined calculation is, for example, subtracting, adding or multiplying a predetermined numerical value with respect to the stored random value R, or square or cube the random value R. This is an operation such as calculating the answer by substituting the value R into a predetermined function. Next, proceeding to S195D, a process of comparing the calculation result with the probability variation winning allowable value is performed. The probability variation winning tolerance is an tolerance that can improve the probability of occurrence of a big bonus game. Two types of probability variation winning allowances are defined: a probability variation twice winning allowance that generates a probability variation state twice, and a probability variation once winning allowance that generates a probability variation state only once. . If the calculation result is within the range of the probability variation two-time winning allowable value in S195E, the process proceeds to S195F, and a process of setting the scheduled stop symbol of the game number / variable display 25 to “77” is performed and the process proceeds to S195J. move on. On the other hand, if the calculation result is within the range of the probability variation one-time winning allowable value, NO is determined in S195E, YES is determined in S195G, and the process proceeds to S195H. A process of setting the stop symbol to “33” is performed, and the process proceeds to S195J. On the other hand, if the calculation result is not within the range of the probability variation twice winning allowable value and not within the range of the probability variation once winning allowable value, the process proceeds to S195I, and the scheduled stop symbol of the game number / variable indicator 25 is displayed. A process for setting the stoppage symbol is performed.

Next, in S195J, a timer for variably displaying the game number / variable indicator 25 is set, and variable display is controlled to start. Next, the process proceeds to S195K, where it is determined whether or not the set timer has expired. Then, when the timer expires, the process proceeds to S195L, and the game number / variable display 25 is controlled to be the stop symbol set by S195F, 195H or 195I. Next, the process proceeds to S195M, where it is determined whether or not a special gaming state where the stop symbol is “77” has occurred. If “77”, the process proceeds to S195N and the probability variation counter is set to “2”. Processing for setting is performed, and the process proceeds to S195Q. On the other hand, if a special gaming state in which the stop symbol is “33” has occurred, a determination of YES is made in S195O, the process proceeds to S195P, a process of setting the probability variation counter to “1” is performed, and S195Q Proceed to If the stop symbol is an off symbol, the processing of S195N and S195P is not performed. Next, the process proceeds to S195Q, where it is determined whether or not the value of the probability variation counter is “0”. If it is “0”, the process proceeds to S196, but if it is not “0”, the process proceeds to S195R, where the game effect is achieved. After the lamp is blinked in the third mode and the probability variation state in which the big bonus game occurrence probability is improved is displayed to the player, the process proceeds to S196. Note that the step S195S may be inserted after this S195R. This S195S is a process of setting the small combination determination mode to “when high probability”. As a result, when the probability variation counter is not “0”, the small role determination mode is set to “when high probability”. By performing the processes of S175 and S195S, if the probability changes, the big bonus winning probability is improved and the small bonus payout rate at “high probability” is 100% (so-called equal multiplication). You can play the game without reducing coins until you win. In this embodiment, the variable display for lottery display of whether or not to change the probability variation state is constituted by the game number / variable display 25 for displaying the number of games. However, a variable display dedicated to the lottery may be provided. Good. Alternatively, lottery display may be performed using the reels 6L, 6C, 6R. Further, the number of probability fluctuations is not limited to two, and may be one or three or more. Further, instead of or in addition to changing the number of probability fluctuations, the winning probability at the time of changing probability may be made different. In S195N and S195P, the probability variation counter is set to “2” and “1”. Instead, each time these steps are executed, +2 and +1 are performed. Also good. When the probability variation counter is not “0”, the winning may be invalidated or the lottery may not be performed.

  Furthermore, the lottery time for determining whether or not the probability change is performed is not limited to the embodiment. For example, when a big bonus is won, when a big bonus occurs, when the big bonus game ends, when a specific small role occurs, when replaying, when a bonus is won, when a bonus occurs, the next game after the bonus game ends, etc. It may be the time. The value to which a predetermined valuable value is given when the display result of the variable display device becomes a predetermined specific display mode by the S176 to S200, the coin hopper 37, the coin payout motor 38, and the payout coin sensor 39. The giving means is configured. Further, the gaming state of the gaming machine is determined in advance by the table data shown in S195B to S195P, S77A, S77B, S67, FIGS. 10 (a), (b), FIGS. 11 (a), (b). Probability variation control means is configured to vary the probability that the display result of the variable display device becomes the specific display mode when a special gaming state is entered.

  Next, in S196, it is determined whether or not the game is over. If the reset switch 4 is operated to be ON when the power is turned on, the game is not over as described above (see S3). If the reset switch 4 is operated to be OFF, the game is over as described above. (Refer to S2), it is determined whether or not the game is over by this S196, and if the game is not over, the process proceeds to S200, and thereafter the game start process shown in FIG. Is started. On the other hand, if it is determined that the game is over, the process proceeds to S197, where the code “OF” is displayed on the payout number display 27 and a process for generating a game over sound from the speaker 28 is performed. As a result, the slot machine is over the game (stopped state). Then, the process proceeds to S198, where it is determined whether or not there is a reset operation, and the process of S197 is continued until there is. If the attendant at the game hall inserts a predetermined key into the reset keyhole 3b and operates the reset switch 4, a determination of YES is made in S198, and the process proceeds to S199, where the code display of “OF” is cleared, After the game over sound is stopped, the process proceeds to S200. By configuring in this way, according to the business form of the game hall, the stop means functions by the stop selection means in the game hall where the prize exchange is performed each time the slot machine reaches the stop state. On the other hand, in a game hall that employs a so-called non-quantitative system that continues the game without exchanging prizes even if the slot machine reaches the stop state, stop selection means May be selected so that the stopping means does not function.

  As another method for controlling the stop of the slot machine in accordance with the business form of such a game hall, there are the following methods.

  Next to the process of S195 shown in FIG. 17, for example, a timer for automatic reset is set, the process of displaying the code “OF” and generating a game over sound, and then determining whether or not there is a game over Prepare. If it is determined that the game is not over, the process proceeds to a step of determining whether or not the automatic reset timer has expired. If the timer has not expired, the code “OF” is displayed again and Return to the step of generating a game over sound. Then, when the automatic reset timer expires, a process of clearing the code display and stopping the game over sound is executed, and then the process returns to S200 shown in FIG. On the other hand, in the step of determining whether or not the game is over, if it is determined that the game is over, the process proceeds to a step of determining whether or not there is a reset operation. If it is determined that there is no reset operation, the process returns to the process of displaying the code “OF” and generating a game over sound. If it is determined that there is a reset operation, the process proceeds to the process of clearing the code display and stopping the game over sound, and then proceeds to S200 in FIG.

In other words, when the game over is not set by S1 to S3, the CPU automatically waits for the automatic reset timer to end and clears the code display indicating that the game is over automatically at the end. The game over sound is stopped and the process returns to the game start process. When game over is set, a code indicating the game over is displayed until the reset switch 4 is operated, and a game over sound is generated from the speaker. To keep the stopping state. The step of determining whether or not there is a reset operation and the processing step of clearing the code display and stopping the game over sound constitute manual stop release means for releasing the stop by manual operation. Yes. In addition, S1 to S3 constitute stop release mode selection means for selecting either stop release by the automatic stop release means or stop release by the manual stop release means. According to this alternative embodiment, when the game has no game over mode, once the big bonus game is over, the game is over (stopped) once, and the game over automatically occurs after a predetermined time has passed. Since the game is released, the game is not played for a predetermined time when the game is over. As a result, when the profit information such as inserted coins and the disadvantage information such as premium coins are totaled by the hall management computer, the game over state where the game is not played is separated to the next game over or the big game over. It is also possible to total information from the start of the bonus game to the game over as a unit.

  Note that coins are not lent during the period from the start of reel rotation to the end of coin payout, but may be lent out at all times. Further, the present invention may be a slot machine that uses a pachinko ball instead of coins to play a game. In that case, the betting number input means detects the number of pachinko balls inserted by the player as the betting number. Further, a slot machine in which a recording medium such as a card is inserted and a game is played using a valuable value owned by the player specified by the recording information of the recording medium may be used. In this case, the operation detection means for detecting the player's operation for using a part of the valuable value owned by the player as the bet number becomes the bet number input means. Further, the variable display device may be automatically stopped when a predetermined time elapses without the stop button, or the variable display device may be variably started by inputting the bet number without the start lever. The value to which a predetermined valuable value is given when the display result of the variable display device becomes a predetermined specific display mode by the S176 to S200, the coin hopper 37, the coin payout motor 38, and the payout coin sensor 39. The giving means is configured. This value giving means may be, for example, paying out a pachinko ball or adding a score and paying out a recording medium on which the score is recorded at the end of the game, instead of paying out a coin as a prize. Note that the variable display device is not a rotating reel type, but a variable display device that displays an image by an electric display device such as a CRT, liquid crystal, LED, electroluminescence, or a plurality of discs on which a pattern is drawn. Any type of variable display device may be used, such as a variable display that rotates, a belt on which a pattern is drawn, or a so-called leaf type. Further, the number of variable display portions is not limited to three.

  Coins and credits are examples of gaming value. A prepaid card represented by a common card is an example of a recording medium. In order to instruct to lend a predetermined amount of game value in exchange for the player-owned valuable value specified by the processing device control unit 80, the lending button 71, and the lending switch 72 based on the record information of the recording medium. The lending instruction means is configured.

  The symbols shown in FIG. 3 constitute a plurality of types of identification information. The symbols “A” and “B” constitute predetermined special gaming state identification information. Further, in addition to the big bonus game and the bonus game, the display result for generating the small combination constitutes a predetermined specific display mode of the display result of the variable display device.

  The payout motor 38 constitutes lending means for lending the predetermined amount of game value in response to the operation of the lending instruction means.

  If it is determined in S41A in FIG. 8 that there is a coin lending signal, the lending number is set to 50 in S41B, and the processes from S41C to S41G are repeated until the lending number becomes 0, during which other processing is performed. It is disclosed that after the renting of the predetermined amount of gaming value by the lending means is started, subsequent processing is prohibited until the renting of the predetermined amount of gaming value is completed.

  Game media scheduled to be lent from the lending means in response to the operation of the lending instruction means by temporarily storing the lent number in S41B of FIG. 8 and decrementing the lending number by -1 in S41E and S41F, respectively. It is disclosed that the number is stored and the number of game media scheduled to be lent is updated correspondingly each time one of the game media is paid out by the lending means.

  Next, another embodiment of the present invention will be described.

  (1) As a special gaming state in which the probability variation start condition is satisfied, for example, when the calculation result of S66 becomes a part or all of the value within the range of the big bonus winning allowable value, the regular bonus winning allowable When it becomes part or all of the values within the range of values, or part or all of the values within the range of each small part winning tolerance, it is part or all within the range of the re-game winning tolerance It may be generated when the value becomes a part of the value within the range of deviation.

  (2) The special gaming state may occur when the big bonus game or the regular bonus game is finished in a specific pattern. For example, a case where a bonus game is generated at a specific number of games in the big bonus game, or a case where a JAC prize is generated at a specific number of games in the bonus game is conceivable. Further, a special gaming state may be generated when the combination of the number of games at the time of the bonus game occurrence and the number of games at the time of the occurrence of the JAC prize becomes a specific pattern.

  (3) A special gaming state may be generated when the variable display device including the reels 6L, 6C, and 6R has a display result determined to start probability fluctuation. For example, when a dedicated symbol is provided in the symbol arrangement of the reel and the symbol stops on the effective line (winning line), or a part of the symbol combination that becomes out of order (for example, “AAB”) It is conceivable that a special gaming state is established when the combination of symbols stops on the active line (winning line).

  (4) For a predetermined period (predetermined number of games or predetermined cumulative number of coins inserted), a special gaming state may be entered when no big bonus game is generated. For example, when a big bonus game or a regular bonus game does not occur for a predetermined period, when a big bonus game does not occur for a predetermined period, or when a regular bonus game occurs a predetermined number of times without generating a big bonus game for a predetermined period, etc. You may make it become.

  (5) A special gaming state may be established when the difference between the gaming machines or the payout rate reaches a predetermined value. In this case, it is conceivable that the difference number and the payout rate are counted from when the game hall is opened, from when the previous big bonus game ends, or from when the probability setting is changed.

(6) When performing the probability variation control, the number of symbol combinations of the variable display device in which the big bonus game is generated may be increased. In this way, when the actual occurrence probability is improved, the occurrence probability for display of the variable display device is also improved.

(7) When the probability change state is reached, (i) only the big bonus game occurrence probability, (ii) only the regular bonus game occurrence probability, (iii) only each small role occurrence probability, (iv) only the regame occurrence probability, You may make it carry out fluctuation control. Alternatively, among the above (i) to (iv), 2
The probability variation control may be performed by selecting more than one. In the case of performing probability variation by selecting two or more of these, the opportunity of probability variation may be the same or different for each probability variation object.

  (8) As a condition for ending the probability variation state, the condition may be ended when the same condition as the start condition of (1) is satisfied. In this case, the specific value with which the calculation result of S66 is compared may be the same value as the start condition of (1) or may be a different value.

  (9) The probability variation may be terminated when the same condition as the probability variation start condition shown in (2) is satisfied. In that case, the number of games and the specific pattern shown in (2) may be the same as or different from the probability variation start condition. Further, the probability variation state may be ended when a bonus game does not occur at a specific number of games in the big bonus game or when a JAC prize does not occur at a specific number of games in the bonus game. Further, the probability variation state may be terminated when the combination of the number of games in which the bonus game has occurred and the number of games in which the JAC winning has occurred does not have a specific pattern.

  (10) The probability variation state may be terminated when the variable display device from the reels 6L, 6C, 6R has a display result determined to terminate the probability variation. Specifically, a dedicated symbol is provided in the symbol arrangement of the reel, and when the symbol stops on the active line, or a part of the combination that becomes the off symbol is defined as a display result that the probability variation ends, The case where the combination of the symbols stops on an active line etc. can be considered. In these cases, some of the dedicated symbols and combinations may be the same as or different from the symbols and combinations defined in the start condition (3). Further, the probability variation state may be terminated when a display result in which a regular bonus is generated or a display result in which a specific small combination is generated.

(11) The probability variation state may be terminated when a predetermined period has elapsed after the probability variation is started. For example, (i) after the probability variation state starts, the game may be terminated when a predetermined number of games is reached or when a predetermined cumulative number of coins is reached. Alternatively, (ii) the probability variation state may be terminated when a combination that is the target of the probability variation control shown in (7) occurs a predetermined number of times. Furthermore, the probability variation state may be terminated when the earlier one of (i) and (ii) is satisfied.

  (12) The probability fluctuation state may be terminated when the difference number of gaming machines and the payout rate reach predetermined values. It is conceivable that the difference number and the payout rate are counted from the time when the game hall is opened, the probability setting is changed, or the probability fluctuation is started.
