Abstract

PROBLEM TO BE SOLVED: To provide a slot machine without lowering amusement of games by a change in an accumulated value at a time of changing a degree of advantage and therefore having a low possibility that a player detects a change in the degree of advantage.SOLUTION: As shown at a time t3, if a setting value is not changed when a slot machine 1 is restored from a power interruption, the number of digested games is kept at 586 games as it has been. On the other hand, as shown at a time t6, if the setting value is changed when the slot machine 1 is restored from the power interruption, the number of digested games is changed from 726 games to an acquired random number value of 115 games.SELECTED DRAWING: Figure 9

Description

  The present invention is provided with a variable display unit capable of variably displaying a plurality of types of identification information, each of which can be identified, and after the variable display unit is variably displayed, the display result is displayed by stopping the variable display of the variable display unit. The present invention relates to a slot machine which can be derived and a prize can be generated according to the display result.

  The slot machine generally includes a variable display unit having a plurality of (usually three) reels on the outer peripheral portion of which a plurality of types of symbols are drawn as identification information, and each reel has a player's start lever Start the rotation by operating. By the player operating the stop button provided corresponding to each reel, the rotation is stopped within the range of the predetermined maximum delay time from the operation timing. Then, a prize is generated according to the display result derived when the rotation of all the reels is stopped.

  As types of winning combinations, there are types such as small roles, special roles, and re-play roles. Here, in the case of the small winning combination, the player can obtain a benefit that the number of medals determined for each kind of small winning combination is paid out. In the special part winning, the player can gain the benefit of being transferred from the next game to the player's advantageous gaming state such as regular bonus and big bonus. In the case of winning the replay role, it is possible to obtain the advantage that the next game can be played without consuming new medals in setting the number of bets.

  Conventionally, there has been a slot machine in which the number of digested games, which is an accumulated value accumulated as the game progresses, is replaced with the initial value when the set value, which is an advantage for the player, is changed (for example, patent Literature 1).

JP, 2016-119991, A

  In the slot machine disclosed in Patent Document 1, since the stored value changes to the initial value each time the degree of advantage is changed, the interest of the game decreases. Furthermore, in this slot machine, there is also a possibility that the player recognizes that the advantage is changed as a clue that the stored value has been replaced by the initial value.

  The present invention has been conceived in view of such circumstances, and the purpose thereof is that the player is made aware of the change in the degree of interest without reducing the interest of the game due to the change in the accumulated value at the time of change of the degree of advantage. Providing a slot machine that is less likely to

(1) A variable display unit capable of variably displaying a plurality of types of identification information that can be identified,
After the variable display unit is variably displayed, a display result is derived by stopping the variable display of the variable display unit, and in a slot machine (for example, slot machine 1) where winning can be generated according to the display result,
Advantage changing means (for example, setting change processing executed by the main control unit 41 shown in FIGS. 6 and 11) for changing the degree of advantage (for example, setting value) for the player;
Processing of Sf 4 based on random number clock generation circuit 43 executed by random number value generation means (for example, main control unit 41 shown in FIG. 6) for generating random number values (for example, numerical values randomly acquired in the range of 1 to 256) )When,
Storage means (for example, RAM 91c) for storing accumulated values (for example, the number of digested games) accumulated with the progress of the game;
The stored value stored in the storage means becomes an initial value (for example, 0 game) by reaching a predetermined value (for example, 1000 games (ceiling)) (for example, time t7 in FIG. 9 and time t6 in FIG. 10). As shown in, when reaching 1000 games, the number of digested games becomes 0),
If the advantage is not changed by the advantage changing unit when the slot machine recovers from the power interruption, the accumulated value stored in the storage unit is maintained at the accumulated value before the interruption (eg, As shown at time t3 in FIG. 9 and time t3 and time t5 in FIG. 10, when the setting is not changed when returning from power failure, the number of digested games does not change. When it happens, a value corresponding to the random number value is substituted in place of the accumulated value stored in the storage means (for example, as shown at time t6 in FIG. The random number value 115 is substituted for the number of digested games, processing of Sf 5 shown in FIG. 7 (A) and FIG.

  According to such a configuration, when the slot machine recovers from the power failure, the stored value replaces the value corresponding to the random value when the degree of advantage is changed. For this reason, it is possible to prevent the interest of the game from being reduced by replacing the accumulated value with the initial value each time the degree of advantage is changed. Furthermore, when the slot machine recovers from power failure, the accumulated value is maintained when the advantage is not changed, while when the advantage is changed, the accumulated value replaces the value corresponding to the random value. For this reason, when the degree of advantage is changed, the difference between the accumulated value when the degree of advantage is changed and when the degree of advantage is not changed can be smaller than when the accumulated value replaces the initial value. . Therefore, even when the degree of advantage is changed, it is less likely that it is recognized that the accumulated value is changed to the degree of advantage.

(2) In the slot machine of (1) above,
It further comprises a privilege giving means (for example, processing in which the main control unit 41 gives a navistock) for giving a privilege (for example, navistock),
The privilege giving means gives a privilege when the stored value stored in the storage means reaches the predetermined value (for example, when the number of digested games reaches 1000 games (ceiling) as shown in FIG. 8) At least one of 1 to 4 navistock is given by AT lottery).

  According to such a configuration, when the stored value reaches the predetermined value, the privilege is given, and the interest is improved.

(3) In the slot machine of (1) above,
It further comprises a benefit lottery means (for example, a process in which the main control unit 41 performs an AT lottery) that determines whether or not to award a benefit (for example, navistock) by lottery.
The bonus lottery means determines whether or not to award a bonus when the accumulated value stored in the storage means reaches the predetermined value (for example, when the number of digested games reaches 1000 games) The main control unit 41 performs AT lottery),
The accumulated value stored in the storage means becomes the initial value by reaching the predetermined value regardless of whether or not the award of the benefit is determined by the benefit lottery means (for example, the number of digested games is 1000) In the AT lottery that is performed when the game reaches the goal, the number of digested games is set to 0 regardless of whether the AT is won or not).

According to such a configuration, it is determined by lottery whether or not to award the benefit when the accumulated value reaches the predetermined value, and the accumulated value reaches the predetermined value regardless of whether or not the award of the privilege is determined. It becomes an initial value by doing. For this reason, it is easy for the player to understand that the accumulation value is accumulated to aim at the predetermined value again.

(4) In the slot machine according to any one of the above (1) to (3),
It further comprises display means (for example, a liquid crystal display 51) for displaying the accumulated value stored in the storage means,
The display means displays a value corresponding to the initial value regardless of the stored value stored in the storage means when the slot machine recovers from power interruption (for example, as shown at time t5 in FIG. 10). When you return from the power-off, the number-of-digestion game number display becomes 0 game),
When the slot machine recovers from power interruption, the accumulated value stored in the storage means is updated as the game progresses (for example, as shown at time t5 in FIG. The number of games is updated from the same 726 as before the power failure return), and the value displayed on the display means is updated from the initial value as the game progresses (for example, as shown at time t5 in FIG. 10) When the power returns from the power-off, the number display of digested games is updated from 0).

  According to such a configuration, when the slot machine recovers from power failure, a value corresponding to the initial value is displayed regardless of the stored value, and when recovered from power failure, the stored value is updated as the game progresses. On the other hand, the value displayed on the display means is updated from the initial value as the game progresses. For this reason, when a plurality of slot machines recover from a power failure simultaneously, these slot machines will display a value corresponding to the initial value, so that there is no difference in the display for each slot machine be able to.

(5) In the slot machine according to any one of the above (1) to (4),
The storage means stores a specific value (for example, a failure point) different from the accumulated value and accumulated as the game progresses (for example, as shown in FIG. 9 and FIG. 10, failure points) Store in RAM 41c),
Even when the degree of advantage is changed by the degree-of-interest change means, the specific value stored in the storage means is maintained at the specific value before the power failure (for example, as shown at time t6 in FIG. 9) , Even if the setting change process is executed, the failure point is maintained at 3),
The slot machine executes a suggestive effect means for suggesting an effect indicative of an accumulation state of the specific value stored in the storage means (for example, when the sub control unit 91 accumulates a failure point in the liquid crystal display 51 Part is displayed as cracked, and further equipped with a process to widen the range where the screen looks like cracked according to the accumulation of failure points,
The indication effect means does not execute the indication effect in a specific period (for example, 20 G) after the slot machine recovers from power interruption (for example, a specific period after time t5 in FIG. 9 and time t5 in FIG. 10) Does not give suggestions that suggest the accumulation of failure points).

  According to such a configuration, the suggestion effect that suggests the accumulation state of the specific value is not executed in the specific period after the slot machine recovers from the power failure. For this reason, it is possible to prevent the player from determining the difference in the presentation status after the power failure return.

(6) In the slot machine according to any one of the above (1) to (5),
When the slot machine recovers from power interruption and the degree of advantage is changed by the degree-of-interest change means, the random number value is substituted as it is instead of the accumulated value stored in the storage means (for example, FIG. As shown at time t6, the random number 115 is substituted as it is for the number of digested games),
The maximum value of the random number is a value smaller than the predetermined value (for example, the maximum value of the random number is a value smaller than 1000).

  According to such a configuration, when the degree of advantage is changed, the random value is substituted as it is instead of the accumulated value, and the maximum value of the random value is a value smaller than the predetermined value. Therefore, it is possible to prevent the player from generating an advantageous situation when the stored value suddenly reaches the predetermined value.

(7) In the slot machine according to any one of the above (1) to (6),
It further comprises predetermined control means (for example, AT lottery process, CZ lottery process, freeze lottery process executed by the main control section 41) for executing predetermined control,
The random number value is also used in the execution of the predetermined control by the predetermined control means (for example, in the AT lottery process, the CZ lottery process, and the freeze lottery process, any random value is acquired from 1 to 256) ).

  According to such a configuration, since the random number value is also used in the execution of the predetermined control, it is possible to reduce the processing load of random number value acquisition after power failure recovery.

(8) In the slot machine according to any one of the above (1) to (7),
An advantage change control means (for example, as shown in FIG. 6) that can be controlled to an advantage change state of changing the degree of advantage by the above advantage change means based on the operation of the operation means (for example, setting key switch 37). And a process of controlling the setting change state based on the operation of the setting key switch 37 executed by the main control unit 41,
The random number generation means generates the random number after a predetermined period of time after being controlled to change the degree of interest (for example, generates a random number by the process of Sf 4 shown in FIG. 6).

  According to such a configuration, since the random number value is generated after a predetermined period after being controlled to the advantage change state, it is possible to perform the generation process of the random value at the timing related to the advantage change state.

(9) In the slot machine according to any one of the above (1) to (7),
Advantage degree change control means (for example, as shown in FIG. 11) that can be controlled to an advantage change state in which the degree of advantage by the degree of advantage change means is changed based on the operation of the operation means (for example, setting key switch 37) And a process of controlling the setting change state based on the operation of the setting key switch 37 executed by the main control unit 41,
The random number value generation means generates the random number value when an operation for ending the control to the advantage change state is performed by the operation means after being controlled to the advantage change state (for example, the random number value generation means) When an operation to turn off the setting key switch 37 is performed in Sg10 shown in FIG. 11, a random number value is generated by the process of Sg11.

  According to such a configuration, since the random number value is acquired when the operation for ending the control to the advantage change state is performed by the operation means after being controlled to the advantage change state, the advantage change state The generation process of the random value can be performed at the timing related to.

  An embodiment for implementing a slot machine according to the present invention will be described below on the basis of an embodiment. In the following embodiments, an example in which the present invention is applied to a slot machine will be described.

[Slot machine configuration]
FIG. 1A is a front view of the slot machine according to the present embodiment, and FIG. 1B is a view showing an example of the main internal configuration of the slot machine 1. As shown in FIG. 1A, in the slot machine 1, the front door 1b is provided with the liquid crystal display 51, and the reels 2L, 2C, 2R arranged in parallel inside the housing 1a through the see-through window 3 are present. It becomes visible. As shown in FIG. 2, on each reel, a plurality of kinds of symbols that can be identified are arranged in a predetermined order.

  As shown in FIG. 1 (a), the front door 1b is determined according to the gaming state within the range of credits stored as gaming value (number of medals) owned by the player as an example of operation means MAXBET switch 6 operated when setting the specified number of bets, the medals stored as credits and the medals used for setting the number of bets are settled (the medals used for setting the credits and the number of bets) Used when returning the game), the start switch 7 operated when starting the game, the stop switches 8L, 8C, 8R operated when stopping the rotation of the reel, and the effect A presentation switch 56 for the purpose is provided.

  The front door 1b is provided with a game display unit 13 for reporting information on a game, as an example of the notification means. A credit display 11 on which the number of medals stored as credits is displayed, a gaming assistance display 12 on which the number of medals paid out and an error code etc. are displayed in the event of an error being displayed on the gaming display unit 13 1 BET LED 14 for reporting the number, 2 BET LED 15, 3 BET LED 16, input request LED 17 for notifying that the medal can be inserted, start effective LED 18 for notifying that the game start operation is possible by the operation of the start switch 7, and Replay An LED 20 during replay is provided to notify that the replay game after winning is in progress. The game display section 13 is provided with an advantageous section notification lamp 19 for notifying that it is in the advantageous section described later by lighting the LED lamp.

  When playing a game in the slot machine 1, first, a specified number of bets (for example, 3) are set by inserting medals into the medal insertion unit 4 or operating the MAX BET switch 6 or the like. As a result, the pay line LN is activated, and the operation to the start switch 7 is activated, and the game can be started. If a medal is inserted with the bet number set, that amount is added to the credit.

  The winning line is a line for determining whether the combination of symbols displayed in the see-through window 3 of the reels 2L, 2C, 2R is a combination of winning symbols. In the present embodiment, an example in which only one pay line LN is provided will be described, but a plurality of pay lines may be provided. In addition, invalid lines LM1 to LM4 are provided to make it easy to recognize that the combination of the symbols constituting the winning is aligned with the pay line LN.

  When the start switch 7 is operated in a state where the game can be started, the reels 2L, 2C, 2R are rotated to variably display the symbols, and when the stop switches 8L, 8C, 8R are operated, the corresponding reels are rotated. By stopping, three symbols are derived and displayed on the upper, middle, and lower portions of the transparent window 3 as display results. When a combination of winning symbols is stopped on the winning line LN and a winning occurs, a predetermined number of medals are awarded to the player according to the winning, and the credit addition or the credit reaches the upper limit number (50). When it is determined, the medal is paid out from the medal payout opening 9.

  As shown in FIG. 1B, inside the slot machine 1, a game control board 40 which controls the progress of the game and outputs various commands in accordance with the progress of the game, and a predetermined effect according to the command. An effect control board 90 to control is provided. The game control board 40 includes a main control unit 41 that performs processing on the progress of the game and controls a configuration mounted or connected to the game control board 40, and a random number clock generation circuit 43. The random number clock generation circuit 43 is a circuit that generates a random number clock. The main CPU 41a generates a random number value based on the random number clock. In this embodiment, random numbers in the range of 1 to 256 are generated. The effect control board 90 receives a command transmitted from the game control board 40 and performs processing for performing effects, and also includes a sub control unit 91 that controls the configuration mounted or connected to the effect control board 90.

  The main control unit 41 is constituted by a one-chip microcomputer and incorporates a RAM 41c used as a work memory and a main CPU 41a which performs control operation according to a program, and performs processing related to the progress of the game and a game control board Control each part of the control circuit mounted on 40 directly or indirectly. When the MAX BET switch 6, the start switch 7, the stop switches 8L, 8C, 8R, and the settlement switch 10 are operated, a detection signal for detecting the operation is input to the main control unit 41. The main control unit 41 detects an operation on the various switches based on detection signals from the various switches. From the main control unit 41, a control signal for performing lighting control or display control of various displays included in the game display unit 13 is output to the game display unit 13. Various displays included in the game display unit 13 light up or display predetermined information based on a control signal from the main control unit 41.

  Connected to the game control board 40 is a power supply board 101 for generating a drive power source of the electric component. The power supply substrate 101 is externally supplied with a power of 100 V AC, and the DC 100 V power generates a DC voltage necessary to drive the electric components of the slot machine 1. The voltage generated by the power supply substrate 101 is supplied to the effect control substrate 90 connected via the game control substrate 40. A setting key switch 37 for performing setting change processing described later is connected to the power supply substrate 101.

Although not shown, the game control board 40 includes a power failure detection circuit, a reset circuit, and an RTC (real time clock). The power failure detection circuit monitors the power supply voltage supplied to the slot machine 1. The power failure detection circuit is a circuit that outputs a voltage drop signal to the main control unit 41 when it detects a voltage drop (for example, determines whether or not the voltage is less than a predetermined voltage). The main control unit 41 is provided with an interrupt input terminal, and an external interrupt occurs when the voltage drop signal is input to the interrupt input terminal, and a power-off interrupt process is performed according to the external interrupt. Run. Further, the main CPU 41a executes timer interrupt processing at fixed time intervals (about 0.56 ms in the present embodiment).

  The reset circuit outputs a reset signal to the main control unit 41 when the voltage rises to a level at which the main control unit 41 can be activated when the power is turned on, thereby activating the main control unit 41. Further, the reset circuit counts up when the value of the reset counter is not cleared based on a signal periodically output from the main control unit 41, that is, when the main control unit 41 does not operate for a certain period of time. A reset signal is output to the main control unit 41, and the main control unit 41 is restarted.

  The RTC counts and outputs the current time. The main control unit 41 acquires date and time information including current date information and time information output from the RTC, and executes various processes based on the acquired date and time information. The date information includes at least information on the current "year", "month", "day", and "day of the week". The time information includes at least information on current "hour", "minute" and "second". The RTC stores the measured time in the storage area of the RAM 41c in the form of predetermined date and time information, and rewrites the date and time information of the time storage area for each unit update time. The RTC is normally operated by the power supply from the slot machine 1 when power is supplied to the slot machine 1, and supplied from the backup power supply circuit when the power supply to the slot machine 1 is cut off (cut off). Works with the power supply. Therefore, the RTC can count the current date and time even while the power is cut off. The RTC may be included in the effect control board 90. In this case, the sub control unit 91 acquires date and time information including current date information and time information output from the RTC, and executes various processes based on the acquired date and time information. Further, the RTC stores the measured time in the storage area of the RAM 91 c in the form of predetermined date and time information, and rewrites the date and time information of the time storage area for each unit update time. The other operations of the RTC provided to the effect control board 90 are the same as the operations of the RTC provided to the game control board 40 described above.

  Similar to the main control unit 41, the sub control unit 91 is configured by a one-chip microcomputer, includes a RAM 91c used as a work memory, and a sub CPU 91a that performs control operations in accordance with a program. And control each part of the control circuit mounted on the effect control board 90 directly or indirectly. When the effect switch 56 is operated, a detection signal for detecting that the operation is performed is input to the sub control unit 91. The sub control unit 91 detects an operation on the effect switch 56 based on the detection signal from the effect switch 56. From the sub control unit 91, control signals for controlling the liquid crystal display 51 and the speakers 53 and 54 are output to the liquid crystal display 51 and the speakers 53 and 54, respectively. The liquid crystal display 51 displays predetermined information based on the control signal from the sub control unit 91. The speakers 53 and 54 output sound based on the control signal from the sub control unit 91. Note that FIG. 1B is merely an example, and other configurations are also provided inside the slot machine 1.

[Setting value]
In the slot machine 1 of the present embodiment, the payout rate of medals (the ratio of the total number of medals used for setting the number of bets and the total number of medals paid out by winning) changes. Specifically, the payout rate of medals changes by using the winning probability according to the set value in an internal lottery which will be described later. The set value is composed of six steps of 1 to 6, and, for example, 6 is the highest payout rate, and the payout rate decreases as the values become smaller in the order of 5, 4, 3, 2, 1. That is, from the point of payout rate, the player has the highest advantage when the setting value is set to 6, and the advantages become lower stepwise as the value becomes smaller in the order of 5, 4, 3, 2, 1 Become.

  In order to change the setting value, it is necessary to turn on the power of the slot machine 1 after setting the setting key switch 37 provided in the housing 1a of the slot machine 1 to the on state. When the setting key switch 37 is turned on and the power is turned on, the setting value read from the RAM 41 c of the main control unit 41 is displayed as a display value on the setting value display provided in the housing 1 a of the slot machine 1. A transition is made to a setting change state in which the setting value can be changed by operating the reset / setting switch provided in the housing 1a of the slot machine 1. In the setting change state, when the reset / setting switch is operated, the display value displayed on the setting value display is updated one by one (when the setting 6 is further operated, the setting is returned to the setting 1). Then, when the start switch 7 is operated, the display value is determined as the set value. When the setting key switch 37 is turned off, the determined display value (setting value) is stored in the RAM 41 c of the main control unit 41, and the state shifts to a state where the game can be progressed.

  In order to confirm the setting value, after the game is over, the setting key switch 37 may be turned on in the state where the bet number is not set. If the setting key switch 37 is turned on in such a situation, the setting value read out from the RAM 41c is displayed on the setting value display to shift to a setting confirmation state where the setting value can be confirmed. In the setting confirmation state, the game can not be progressed, and by setting the setting key switch 37 to the off state, the setting confirmation state is ended, and the state of the game can be returned to the progressing state.

[Internal lottery]
After setting the number of bets, when the start switch 7 is operated, an internal lottery is performed by the main control unit 41 to determine whether or not to allow the occurrence of a winning (internal lottery). For example, the random number circuit (not shown) included in the main control unit 41 updates the determination value belonging to the predetermined range (1 to 65,536) in accordance with the predetermined update rule. The main control unit 41 extracts the determination value updated by the random number circuit when the start switch 7 is operated. Then, if the extracted determination value corresponds to a determination value belonging to a predetermined range predetermined for each lottery target combination, the main control unit 41 determines the winning of the corresponding lottery target combination. When the lottery target combination is won in the internal lottery, the winning flag of the winning combination included in the lottery target combination is set in a predetermined area of the RAM 41c. For example, when a BB (bonus) is won, a BB winning flag is set. The BB is a winning combination with transition to the advantageous state of bonus. The bonus ends when the predetermined number of medals or more is paid out. For example, with regard to a bonus controlled by winning or winning a BB, the game ends in a game in which the number of medals paid out during the bonus is 351 or more. When the strong cherry is won, the lower cherries win flag and the one sheet 1 winning flag are set. The winning flag of BB is carried over until the winning BB wins, while the winning flag corresponding to a winning combination other than BB is erased when the winning game is ended regardless of the occurrence of the winning. .

[Normal section and advantageous section]
The section of the game played in the slot machine 1 includes a normal section and an advantageous section. The advantageous section is a section having a performance related to an instruction function of instructing the player the operation mode (pushing order, operation timing) of the stop switches 8L, 8C, 8R. Specifically, the advantageous section is a section controlled to an advantageous state such as AT (assist time) or CZ (chance zone).

The AT is a notification state under control of the main control unit 41 in which navigation effects are performed to notify the player of the operation mode (pushing order, operation timing) of the stop switches 8L, 8C, 8R. Specifically, the main control unit 41 executes an AT lottery relating to the provision of navistock which is the right to be controlled by the AT. For example, the main control unit 41 determines whether or not to give navistock, and the number of giving (navistock number) to give navistock by AT lottery. The navi stock number indicates the number of rights controlled by the AT over a predetermined number of games (50 games in this embodiment). In the AT lottery, the main control unit 41 acquires a random number value from among the numerical values within the range of 1 to 256 generated by the random number clock generation circuit 43 at the start of the game. Then, when the acquired random number falls within a predetermined winning range, the main control unit 41 determines the provision of the navistock. In addition, that it is decided to grant the navistock in the AT lottery is referred to as AT winning, and that not decided to give the navistock in the AT lottery is referred to as non-AT winning.

  When the AT is won by the AT lottery, the main control unit 41 stores the number of AT games according to the given number of navi stock in a predetermined area of the RAM 41c. Then, the main control unit 41 controls the AT over the stored number of AT games. The main control unit 41 stops the symbol combination corresponding to the selected winning combination and advantageous for the player on the pay line LN when the winning combination is won during AT such as pressing bell and pressing replay. The operation mode for the navigation is notified by the navigation effect. Therefore, by being controlled by the AT, the player can easily increase the net increase number of medals. In addition, it is the operation procedure corresponding to the kind of pushing order, Comprising: The thing of the procedure alert | reported by navi presentation is called a correct procedure. On the other hand, an operation procedure which does not correspond to the type of the turn order and which is not notified by the navigation effect is referred to as an incorrect answer procedure. In addition, the main control unit 41 may execute an additional lottery during AT. The addition lottery is a lottery for adding the number of navistocks to the number of navistocks already granted. It is also called an additional winning that it is decided to add the navistock in the additional drawing. When the player is elected to ride on the top, the assigned navistock number is added to the navistock number stored in the RAM 41c.

  CZ is a state controlled to a section advantageous to the player. During CZ, the advantage for control to AT is higher than that during normal (in non-CZ). Specifically, in CZ, the probability of winning AT will be higher than that in non-CZ, or the number of navistocks awarded when AT is won will increase. The main control unit 41 executes a CZ lottery relating to the provision of the CZ game which is the right to control the CZ. In the CZ lottery, the main control unit 41 acquires a random number value from among the numerical values within the range of 1 to 256 generated by the random number clock generation circuit 43 at the start of the game. Then, when the acquired random number falls within the predetermined range, the main control unit 41 determines whether or not to apply the CZ game (CZ winning). Further, the number of CZ games to be awarded (the number of CZ games) is determined. The CZ lottery is executed by winning a specific lottery target role (watermelon and cherries). If it is determined to grant the CZ game in the CZ lottery, control is made to the CZ state, while if it is not decided to grant the CZ game in the CZ lottery, a failure point described later is awarded. . It should be noted that CZ may be advantageous for the player in that the navi effect at which the winning of the maximum payout number is obtained occurs is performed at least once, and the advantage regarding the control to the AT is the same as usual. Good. Of course, the CZ may be advantageous for the player in that the navi effect is executed at least once when a winning occurs with which the maximum payout number is obtained, and the degree of advantage regarding control to the AT becomes higher than usual.

  The number of CZs is not limited to one, and a plurality of CZs may be provided. In this case, although the degree of advantage regarding control to the AT is higher than usual in any CZ, the degree of advantage may be different according to the type of CZ.

[command]
An example of a command that the main control unit 41 transmits to the sub control unit 91 will be described. In the present embodiment, the main control unit 41 sends a setting start command, a setting end command, an internal winning command, a push order command, a reel rotation start command, a reel stop command, a prize determination command, and a gaming state to the sub control unit 91. A plurality of types of commands including a command, an AT winning command, a CZ winning command, and a cross-day command are transmitted.

  The setting start command is a command that can specify the start of the setting change process performed by the main control unit 41. The setting start command is transmitted when the setting change process is started. The setting end command is a command that can specify the end of the setting change process performed by the main control unit 41. The setting end command is transmitted when the setting change process ends.

  The internal winning command is a command that can specify the group to which the lottery target combination that has won according to the result of the internal lottery belongs. The internal winning command is transmitted when the start switch 7 is operated to start the game. The sub control unit 91 can specify the operation of the start switch 7 and the group to which the selected lottery target combination belongs by receiving the internal winning command.

  The push order command is a command capable of specifying an operation procedure (correct procedure) for stopping the symbol combination that is advantageous to the player according to the lottery target combination won in the internal lottery. The pushing order command is transmitted when the start switch 7 is operated and the game is started during the advantageous section. For example, in AT, a push order command capable of specifying a correct procedure is transmitted, and in non-AT, a push order command capable of specifying a correct procedure is not transmitted. Therefore, the sub control unit 91 can specify the correct procedure by receiving the push order command in the AT, but can not specify the correct procedure in the non-AT. During non-AT, a push order command capable of specifying a predetermined standard procedure (for example, left first stop) is transmitted.

  The reel rotation start command is a command for notifying the start of reel rotation. The reel rotation start command is transmitted when the start switch 7 is operated and rotation of the reels 2L, 2C, 2R is started.

  The reel stop command specifies which of the left reel 2L, the middle reel 2C, and the right reel 2R the reel to be stopped is, the area number of the stop operation position of the corresponding reel, the area number of the stop position of the corresponding reel, etc. It is a possible command. The reel stop command is transmitted each time the stop control is performed in connection with the stop operation of each reel. The sub control unit 91 can specify that the stop switches 8L, 8C, 8R have been operated by receiving the reel stop command.

  The prize determination command is a command capable of specifying the combination of symbols arranged on the prize line LN, the presence or absence of a prize, the type of the prize, the number of medals paid out at the prize, and the like. The prize determination command is transmitted after all reels stop and a prize determination is made.

  The game state command is a command that can specify the game state of the next game, the type of RT, and the number of remaining RT games. The game state command is transmitted at the end of the game. Further, in the present embodiment, the gaming state command includes the number of consumed games which is the number of games accumulated in the non-AT state, and information capable of specifying a failure point.

  The AT winning command is a command that can specify the result of the AT lottery and the start timing of the AT.

  The CZ winning command is a command that can specify the result of the CZ lottery and the start timing of the CZ.

The inter-day command is a command capable of specifying whether or not the day is crossed from the time of power failure occurrence to the time of power failure recovery when power is restored. In the present embodiment, as shown in FIG. 9, it is determined whether or not the day span is recovered based on whether or not recovery from power failure has occurred across time Ts (4 o'clock AM). The sun over command is transmitted when the initialization flag 2 is on in the activation process (main).

  The sub control unit 91 performs output control of various rendering devices such as the liquid crystal display 51, the rendering effect LED 52, the speakers 53 and 54, and the reel LED 55 based on the command received from the main control unit 41.

[Game processing]
The main control unit 41 performs game processing to control one game. In the game process, first, a bet number setting, a bet process for credit settlement, bet number settlement are performed.

  When the start switch 7 is operated after setting the number of bets, an internal lottery process is performed to determine whether or not to allow the occurrence of a winning (internal lottery).

  In the internal lottery process, after the internal lottery is performed, an internal lottery command setting process is performed to set a command according to the result of the internal lottery. The main control unit 41 reads out the internal winning flag set by the internal lottery, and sets an internal winning command for specifying a group to which the lottery target combination belongs in the command queue when any lottery target combination is won. For example, when the main control unit 41 wins any of the left bell, the middle bell, and the right bell described later, the main control unit 41 transmits an internal win command capable of specifying a push bell group to which these roles belong. In addition, when any lottery target combination is not won, an internal winning command for specifying an outfall is set.

  When it is determined that the navigation target combination is won during the AT, the main control unit 41 sets, in the command queue, a push order command for specifying a correct procedure corresponding to the navigation target combination. Thereby, on the side of the sub control unit 91, navigation effects can be performed based on the push order command.

  On the other hand, when the main control unit 41 is not in the AT or has not won the navigation lottery target combination, the main control unit 41 sets, in the command queue, push order commands that can specify a predetermined standard procedure. As a result, it is possible to execute an effect according to the group specified from the internal winning command, while making it impossible to specify the correct procedure even if the sub control unit 91 side is injustice.

  When the internal lottery process is completed, a reel rotation process is performed. In the reel rotation process, the rotation of the reels 2L, 2C, 2R is started on condition that a predetermined time (for example, 4.1 seconds) has elapsed from the start of the reel rotation of the previous game, and then the stop switches 8L, 8C. , 8R, and stop the rotation of the reel in response to the stop operation.

  In the reel rotation process, when a predetermined freeze condition is established, a freeze effect is performed which delays the progress of the game for a predetermined period (delays the activation of the stop operation of each of the stop switches 8L, 8C, 8R) After executing the freeze rendering process for making the game, the stop switches 8L, 8C, 8R are activated to shift to the normal game. Based on the winning combination, the main control unit 41 executes a freeze lottery to determine whether to cause a freeze. In the freeze lottery, the main control unit 41 acquires a random number value from among the numerical values within the range of 1 to 256 generated by the random number clock generation circuit 43 at the start of the game. Then, the main control unit 41 determines to execute the freezing when the acquired random number value falls within the predetermined winning range.

  When the reels 2L, 2C, 2R are stopped and the reel rotation process is finished, a winning determination process is performed to determine whether a winning or the like has occurred based on the symbol combination on the payline.

  When the winning determination process ends, a payout process is performed. In the payout process, medal payout or credit addition according to the occurrence of winning, various processes not related to winning (for example, counting the number of medals paid out during a bonus process for bonus termination control, winning without carryover A flag (e.g., a winning flag for a small winning combination / replay role) is erased, and the like. In the game end processing, processing for setting a gaming state is performed in preparation for the next game. Thereby, the game processing for one game is completed, and the game processing for the next one game is started.

[Power-off determination processing (timer interrupt processing (main))]
Next, a power interruption determination process executed in the timer interrupt process (main) executed by the main control unit 41 (CPU 41c) at an interval of 1.12 ms based on the count value of the internal clock will be described. FIG. 2 is a flowchart showing control contents of the power interruption determination process performed in the timer interrupt process (main) performed by the main control unit 41 at regular intervals.

  As shown in FIG. 2, in the power failure determination process, the main control unit 41 saves the register in use in the stack area (Sp1). The main control unit 41 performs a power failure determination (Sp2). The main control unit 41 determines whether or not the voltage drop signal is input from the power failure detection circuit 48 in the power failure determination, and if the voltage drop signal is input, the voltage drop signal is also detected in the previous power failure determination. Is determined, and if the voltage drop signal has been input even in the previous determination of power interruption, it is determined that power interruption (power failure), and a power interruption flag indicating that is set.

  The main control unit 41 determines whether the power-off flag is set (Sp3). When the power-off flag is set (YES in Sp3), the main control unit 41 shifts to the power-off process (main).

  If the power-off flag is not set (NO in Sp3), the main control unit 41 ends the present routine.

[Power-off process (main)]
The power failure process (main) executed by the main control unit 41 in the power failure determination process (timer interrupt process (main)) will be described with reference to FIG. 3. FIG. 3 is a flow chart showing the control contents of the interruption processing (main) which the main control unit 41 executes in the timer interruption processing (main).

  The main control unit 41 acquires date and time information at the time of power interruption (that is, current) from the update time storage area of the RAM 41 c, and stores and holds it in a temporary storage area different from the update time storage area (Sd1). The stored date and time information at the time of power interruption is referred to in the initialization determination process described later.

  The main control unit 41 calculates parity adjustment data so that the RAM parity of all the storage areas of the RAM 41 c becomes 0 in order to determine whether the RAM 41 c is normal or not at the next activation, Store (Sd2).

  The main control unit 41 prohibits the RAM access (Sd3), and sets the interrupt prohibition (Sd4). Thereafter, the main control unit 41 enters loop processing in which no processing is performed. That is, if the voltage drops as it is, the operation is internally stopped. Thereby, the operation of the main control unit 41 is stopped at the time of power interruption.

[Startup process (main)]
The start processing executed by the main control unit 41 when the reset signal is input from the reset circuit 49 will be described with reference to FIG. 4. FIG. 4 is a flowchart showing the control contents of the start process (main) executed by the main control unit 41.

  As shown in FIG. 4, the main control unit 41 initializes the built-in device etc. (Sr1) and permits access to the RAM 41c (Sr2). The main control unit 41 calculates the RAM parity of all the storage areas of the RAM 41c (Sr3), and determines whether the RAM parity is 0 (Sr4).

  In the power-off process, since the RAM parity is adjusted to be 0 beforehand, the main control unit 41 determines that the data stored in the RAM 41 c is normal if the RAM parity is 0 (YES in Sr 4) If the RAM parity is not 0 (NO in Sr4), it is determined that the data stored in the RAM 41c is abnormal.

  When the RAM parity is not 0 (NO in Sr4), the main control unit 41 turns on an error flag indicating that a RAM abnormality has occurred (Sr5).

  On the other hand, when the RAM parity is 0 (YES in Sr4), main control unit 41 performs predetermined initialization based on whether or not setting key switch 37 is turned on, and based on the date and time of power failure and the double charging date and time. An initialization determination process is performed to determine whether the condition is satisfied (Sr6).

  The main control unit 41 determines whether or not the initialization flag 1 is turned on (Sr7). The initialization flag 1 is a flag indicating whether or not the setting has been changed, which is set in the initialization determination process. When the initialization flag 1 is turned on (YES in Sr7), the main control unit 41 executes a setting change process executed by the main control unit 41 (Sr8).

  On the other hand, when the initialization flag 1 is not turned on (NO in Sr7), the main control unit 41 determines whether the initialization flag 2 is turned on (Sr9). The initialization flag 2 is a flag indicating whether the date crossing condition set in the initialization determination process is satisfied. When the initialization flag 2 is turned on (YES in Sr9), the main control unit 41 executes day-crossing processing (Sr10).

  In the date crossing process, the main control unit 41 transmits a date crossing command to the sub control unit 91. Specifically, a command is transmitted that makes it possible to specify that recovery from power failure has been made across time Ts (e.g., AM 4 o'clock).

  On the other hand, when the initialization flag 2 is not turned on (NO in Sr9), the main control unit 41 turns on the normal power failure recovery flag indicating that the power failure is recovered normally (Sr11).

  When one of Sr5, Sr10, and Sr11 processing is completed, the main control unit 41 indicates that the main control unit 41 is waiting to receive a return command indicating that the control state has been restored. The waiting flag is set in the RAM 41c (Sr12), the interrupt is permitted (Sr13), and the processing shifts to the loop processing.

[Initialization judgment processing]
The initialization determination process executed by the main control unit 41 in the activation process (main) will be described with reference to FIG. FIG. 5 is a flowchart showing the control contents of the initialization determination process performed by the main control unit 41 in the activation process (main).

  When the power of the slot machine 1 is switched from the off state to the on state, the main control unit 41 determines whether the setting key switch 37 is in the on state (St1). When the setting key switch 37 is in the on state (YES in St1), the main control unit 41 turns on the initialization flag 1 (St2), and ends this routine.

  On the other hand, when the setting key switch 37 is not in the on state (is in the off state) (NO in St1), the main control unit 41 acquires date and time information at power recovery (ie current) from the update time storage area of the RAM 41c ( St3). Since the date and time control process in the timer interrupt process is not executed during the power interruption, the date and time information stored in the update time storage area immediately after the power recovery becomes almost the same as the date and time information at the time of the power interruption. Therefore, in St3, the main control unit 41 acquires date and time information at the time of power recovery (that is, current) from the update time storage area of the RAM 41 c after at least one date and time control process is executed after power recovery.

  Next, the main control unit 41 acquires date and time information at the time of power failure that was held at the time of power failure from the temporary storage area of the RAM 41 c (St4).

  The main control unit 41 determines whether or not the power recovery time is after 4 AM (St5). If the power recovery time is after 4 AM (YES in St5), the main control unit 41 turns on the initialization flag 2 (St6), and ends this routine. On the other hand, when the power recovery time is not after 4 AM (NO in St5), the main control unit 41 ends the present routine.

[Display of number of digested games and number of digested games]
Next, the relationship between the numerical value accumulated in the non-AT state (the state not controlled by the AT and including the non-CZ state and the CZ state) and the power interruption and the setting change will be described. The numerical values accumulated in the normal gaming state include the number of digested games and failure points. The details will be described below.

  The number of consumed games is an accumulated value accumulated as the game progresses in the non-AT state. The number of digested games is stored in a predetermined area of the RAM 41c. When the control state shifts from the AT to the non-AT state, the number of digested games starts updating from 0 and increases by one each time one game is consumed. When the number of digested games reaches 1000, navistock is awarded by the AT lottery described later. When the number of digested games reaches 1000 (the number of so-called ceiling games), the accumulated value stored in the RAM 41c is reset to the initial value (0 in the present embodiment), and the number of digested games is counted again from the next game. Ru.

  The number of digested games can be changed when a power failure occurs. In the present embodiment, the number of digested games is changed when the power failure is restored (crossing the day) across the AM 4 o'clock, which is the non-business hours, and the setting is changed. At this time, the number of digested games is once initialized to 0 by the initial setting process, and a random value in the range of 1 to 256 is set. The main control unit 41 acquires a random number value from among the numerical values within the range of 1 to 256 generated by the random number clock generation circuit 43 in the setting change process. Then, the main control unit 41 stores the acquired random number value in the RAM 41 c instead of the number of digested games. In addition, even if it is across the day, when the setting change is not performed, the number of digested games is not changed and the accumulated value before power-off is handed over. Further, even in the case of a power failure (for example, at the time of a power failure or the like) occurring within business hours, the number of digested games is not changed and the accumulated value before power failure is handed over.

The number-of-digested-games display is the liquid crystal display 51 displaying the number of games based on the number of digested games read out from the RAM 41c. The number-of-digested-games display is generated based on the number of digested games that can be identified from the gaming state command received by the sub control unit 91 from the main control unit 41. Therefore, normally, the number of digested games and the number of digested games are equal. However, as described below, when a power failure occurs, the numbers may differ between the number of digested games and the number of digested games displayed. For example, the number-of-digestions game display is initialized and “0 G” is displayed when the power failure is restored due to crossing over the sun. On the other hand, as described above, the number of consumed games is set to a random number within the range of 1 to 256 when there is a power failure due to crossing over the sun and there is a setting change. On the other hand, if there is a power failure due to crossing over the sun and there is no setting change, the random number value before the power failure is taken over.

  By doing as described above, in the power failure recovery state due to crossing over the sun (the morning one state at the start of business hours), all the digested game numbers of the plurality of slot machines installed in the hall are displayed with "0G". It can be unified. As a result, there is no inequality in the selection of the slot machine of the player in the morning. For example, it is assumed that there is a slot machine in which the number of digested games recorded in the RAM 41 is already 998 games close to the ceiling. If the number-of-digested-games display is displayed as "998G", the player will reach the ceiling in two more games, and the player will be recognized as AT winning. However, as in the present embodiment, in the first morning immediately after the start of business, by unifying and displaying the stored value as "0 G", inequalities due to the selection of players do not occur among players. In the case of power failure recovery due to a power failure during business hours, since there is a high possibility that the player is the same before and after power failure recovery, the display is initialized by “0 game” as described above, It does not make the player feel dissatisfaction due to the value being changed.

  Also, in the power failure recovery state due to crossing over the sun (the morning state at the start of business hours), if there is no setting change, the number of digested games stored in the RAM 41c will be taken over as it is, and if there is a setting change, the RAM 41c will be used. The random number value is substituted for the stored number of digested games. By doing this, it is difficult for the player to recognize whether or not there is a setting change, and inequality does not occur in the selection of the first table in the morning. For example, it is assumed that the number-of-digestion game display is already "960 G" near the ceiling just before the business hours of the previous day. A player who confirms this can reach the ceiling and make AT winning if 40 game games are played on the morning of the next day. However, if the setting is changed and it is initialized and the number of digested games is zero, the game does not reach the ceiling even after 40 games are played. That is, the player recognizes that the setting has been changed only by executing the 40 games. As in the present embodiment, if a random number value is substituted for the number of digested games stored in the RAM 41c when there is a setting change, it is a setting change or a random value setting. Since it becomes difficult to distinguish the player, it is difficult for the player to recognize that the setting has been changed.

[Failure point and suggestion production]
Failure points are accumulated values accumulated as the game progresses in the non-AT state. The failure point is stored in a predetermined area of the RAM 41c. When the control state shifts from the AT to the non-AT state, the failure point starts updating from 0, and increases by one point each time a predetermined condition is satisfied. In the present embodiment, the predetermined condition is a case where a CZ lottery has occurred and a CZ has not been won. When the failure points reach 5 points, an AT lottery is made. At this time, regardless of whether or not the AT is won (whether or not the navistock is given), the failure point is initialized and becomes 0 point. Also, if the AT is won under another condition (for example, reaching the ceiling), the number of digested games is reset to 0 points. When the AT is won by reaching the ceiling, the number of digested games may not be reset to 0 points.

The failure point is different from the number of consumed games, and the data is not changed even when a power failure occurs, and the accumulated value before the power failure occurrence is taken over. Also, unlike the number of digested games, the failure point is not displayed on the liquid crystal display 51 based on the stored value read out from the RAM 41 c. However, the sub control unit 91 executes the suggestion effect that suggests the accumulation state of the failure points, as well as the accumulation of the failure points. Specifically, in the liquid crystal display 51, when failure points are accumulated, a part of the screen is displayed as if it were cracked, which indicates that the failure points are accumulated. As the failure points are accumulated, the range in which the screen is cracked becomes wider according to the accumulation of failure points. In addition, the suggestion effect is not executed in a specific period (for example, 20 games) after returning from the power failure due to the sun over. The reason why the suggestion effect is not performed for a specific period is to prevent the player from noticing that the failure points are accumulated after returning from the power interruption due to the straddling. If a short period such as one game is set as the specific period, the player will notice that failure points have been accumulated by playing one game, so it is inappropriate as the specific period. It is. On the other hand, when 20 games are set as the specific period, it is impossible to know that failure points are accumulated unless 20 games are played. The suggestion effect is executed based on the information of the failure point of the game state command received by the sub control unit 91 from the main control unit 41. In the present embodiment, it is assumed that the suggestion effect indicating the accumulation situation of the execution failure point is not performed in the specific period after returning from the power failure due to the day crossing. However, the present invention is not limited to this, and it may be such that the suggestion effect is not performed at all. That is, as described above, failure points are accumulated as the game progresses in the non-AT state, and are stored in a predetermined area of the RAM 41c, but no suggestion effect by accumulation of failure points is performed at all. However, in the AT lottery when the failure points reach 5 points, when AT is won, the liquid crystal display 51 notifies that effect.

[Setting change process]
The setting change process performed by the main control unit 41 will be described with reference to FIG. FIG. 6 is a flowchart showing the control contents of the setting change process executed by the main control unit 41. The setting change process is a process executed in the activation process (main). In the setting change processing, the setting value is changed based on the operation by the setting switch (or the reset switch), and initialization processing, random number value acquisition processing, and the like are performed.

  The main control unit 41 transmits, to the sub control unit 91, a setting start command that can specify transition to the setting change state (Sf1). Thereafter, the main control unit 41 shifts to the setting change state (Sf2).

  The main control unit 41 performs an initialization process (Sf3). Specifically, the main control unit 41 clears the payout work excluding the failure point and the bonus information. The failure point is data which is not a target of initialization in the initial process by setting change. That is, even when the setting change process is performed, data is maintained before and after that. The payout work is an area in which numerical values (including failure points) relating to the advantageous state such as the AT excluding the bonus are stored, and numerical information regarding the payout. For example, the number of digested games in the non-AT state, data in AT, and data in which CZ can be identified are stored. In initialization processing by setting change, this area is initialized, but only failure points are not initialized exceptionally. Further, the bonus information is an area in which information related to the bonus is stored. For example, data that can identify that a bonus is in progress is stored.

  Next, the main control unit 41 acquires a random number value from the range of 1 to 256 generated by the random number clock of the random number clock generation circuit 43 (Sf 4). Next, the acquired random number value is set as the accumulated value (the number of digested games) stored in the RAM 41c (Sf5). At this time, the main control unit 41 first erases the accumulated value (the number of digested games) stored in the RAM 41 c and substitutes the initial value (0). Next, the main control unit 41 substitutes the random number value as it is in place of the initial value (0) stored in the RAM 41 c. As described above, acquisition of the random value is performed after the setting value change process is started.

  The main control unit 41 reads the current setting value from the RAM 41c, converts the read setting value into a display value (Sf6), and displays the converted display value on the setting value display 24 (Sf7). After that, the main control unit 41 determines whether the setting switch has been operated by the store clerk (Sf8). When the main control unit 41 determines that the setting switch has been operated within the predetermined period (YES in Sf9), the main control unit 41 updates the display value by 1 (Sf9) and displays the updated display value on the setting value display 24 ( Sf 7).

  On the other hand, when determining that the setting switch has not been operated within the predetermined period (NO in Sf8), the main control unit 41 determines whether the start switch 7 has been operated (Sf10). When the main control unit 41 determines that the start switch 7 has not been operated within the predetermined period (NO in Sf10), the process returns to Sf8.

  On the other hand, when the main control unit 41 determines that the start switch 7 has been operated within the predetermined period (YES in Sf10), the main control unit 41 converts the display value displayed on the setting value display 24 into setting values and stores them in the RAM 41c. (Sf11).

  Next, the main control unit 41 determines whether the setting key switch 37 is in the off state (Sf12). If the main control unit 41 does not determine that the setting key switch 37 is in the off state (the setting key switch 37 is in the on state) (NO in Sf12), the process returns to Sf12. On the other hand, when determining that the setting key switch 37 is in the off state (YES in Sf12), the main control unit 41 proceeds to the process of Sg13.

  Next, the main control unit 41 transmits, to the sub control unit 91, a setting end command that can specify that the setting change state is ended (Sf13). Thereafter, the main control unit 41 ends the setting change state (Sf14), and ends the setting change process.

[Random value to substitute for the number of digested games]
The random number value substituted for the number of digested games will be described in detail with reference to FIG. FIG. 7 is a diagram for explaining random numbers to be substituted for the number of digested games. As described above, when the setting change process is performed, the number of digested games is initialized, and the acquired random number value is set to the number of digested games.

  FIG. 7A shows a specific example of the process of changing the number of digested games when the setting change process is executed. It is assumed that the number of digested games stored in the RAM 41 c immediately before the setting change processing is “550”. By executing the setting change process, the number of digested games is initialized, and the numerical value becomes “0” (Sf 3 in FIG. 6). Next, random number values are acquired from the range of 1 to 256 generated by the random number clock of the random number clock generation circuit 43 (Sf 4 in FIG. 6). Here, it is assumed that "115" is acquired as a random number value. Next, the acquired random number value “115” is set as the number of directly digested games (Sf5 in FIG. 6). As a result, the number of digested games stored in the RAM 41c is set to a value of "115".

In the present embodiment, the range of obtainable random numbers is 1 to 256. If it is desired to substitute a numerical value larger than that in the storage area of the RAM 41c, a correction may be made to the acquired random number value. For example, the acquired random number may be multiplied by four and then set as the number of digested games. In the present embodiment, the ceiling of the number of digested games is 1000 games for the range 1 to 256 of the random numbers, so if the random numbers are directly substituted into the storage area of the storage area of the RAM 41c, the range to 257 to 1000 The number of digested games can not be set. For this reason, the number of digested games before the power-off and the number of digested games set by the random number are different. By quadrupling the random number value, it is possible to set a numerical value in the range of 4 to 1024 (256 × 4), so it is possible to set a numerical value closer to the number of digested games before power interruption.

  FIG. 7B shows a specific example in which the acquired random number is quadrupled. It is assumed that the number of digested games stored in the RAM 41 c immediately before the setting change processing is “550”. By executing the setting change process, the number of digested games is initialized, and the numerical value becomes “0” (Sf 3 in FIG. 6). Next, random numbers in the range of 1 to 256 are acquired (Sf 4 in FIG. 6). Here, it is assumed that "115" is acquired as a random number value. Next, the acquired random number value is quadrupled (“115” is changed to “460” (= 115 × 4)). Finally, a numerical value “460” obtained by multiplying the acquired random number by four is set as the number of digested games (Sf5 in FIG. 6). As a result, the number of digested games is set to "460".

  A numerical value in the range of 4 to 1024 (256 × 4) can be obtained by quadrupling the random number value, but may be set to 1000 if it exceeds 1000, which is a ceiling. However, at this time, when numerical values in the range of 1000 to 1024 are obtained, the ceiling is always reached. At this time, the player can start playing the game in the slot machine (that is, in the AT winning state) that has suddenly reached the ceiling at the time of power interruption due to crossing the sun (that is, the state of morning one which is the opening time of the hall). It will The player can play a plurality of slot machines one game at a time in the morning to confirm the presence or absence of AT winning. As described above, if the number of players who do not play a game increases at the stage where AT is not won, the operating rate of the hall will fall.

  In order to avoid such a situation, if it exceeds 1000, which is the ceiling, a numerical value smaller than the ceiling may be set. For example, 980 is the upper limit. As a result, even if the upper limit value 980 is set, it is difficult for the player to determine whether or not the player has reached the ceiling without performing 20 games, so that the rate of operation of the hole is unlikely to drop.

  Further, the acquisition process (Sf4 in FIG. 6) of the random number value executed in the setting change process executed by the main control unit 41 is executed as a common process also in other processing means. For example, also in the AT lottery process, the CZ lottery process, and the freeze lottery process executed by the main control unit 41, the random value acquisition process (Sf4 in FIG. 6) is executed as a common process.

[Navistock grant conditions]
The provision conditions of the navistock (AT winning condition) will be described with reference to FIG. FIG. 8 is a view for explaining the conditions for giving navistock. As shown in FIG. 8, in non-CZ, navistocks can be awarded when the number of digested games reaches the ceiling (1000 games) and when the number of failure points reaches 5 points.

  In non-CZ, when the number of consumed games reaches 1000, AT wins with 100% probability (Navistock is given). The number of navistocks to be granted is determined by the AT lottery shown in FIG. The probability of giving the navi stock number 1 is 40%, the probability of giving the navi stock number 2 is 30%, the probability of giving the navi stock number 3 is 20%, and the navi stock number 4 is The probability of being granted is 10%. The number of consumed games is initialized to 0 game by reaching 1000 games which is the ceiling.

The number of navistocks may not be determined by lottery, but may be a predetermined number of navistocks (for example, 1). In addition, instead of giving the navistock with a probability of 100%, for example, the navistock may not be given with a predetermined probability (for example, 10%). In this case, regardless of whether or not the navistock is awarded (AT winning), the number of digested games is initialized to 0 game by reaching 1000 games which is the ceiling. In addition, it may be made to draw a lottery whether or not the navigation stock is given for every predetermined number of games (for example, every 100 G) until reaching the ceiling (1000 G). For example, the navistock is given with a probability of 50%. When the player wins the Navistock, the number of digested games is initialized (it is assumed to be 0 game), and when the player is not won, the number of digested games may be continued without being initialized.

  In addition, in the non-CZ, when the failure point reaches 5 points, an AT lottery (a lottery as to whether or not to give the navistock) is performed. The probability of not winning the AT is 20%. There is an 80% chance that AT will be won and navistock will be awarded. When navistocks are awarded, the number of navistocks to be granted is determined by lottery. The probability of giving the navi stock number 1 is 35%, the probability of giving the navi stock number 2 is 25%, the probability of giving the navi stock number 3 is 15%, and the navi stock number 4 is The probability of being granted is 5%. Failure points are initialized to 0 game by reaching 5 points.

  Although not shown, in CZ, the case of winning a specific lottery target combination is the condition for giving navistock. Specifically, it corresponds to a specific lottery target role of watermelon and cherry. If a watermelon or cherry is won, a lottery is made to determine whether or not to give navistock. In case of winning Navistock, the number of Navistock from 1 to 4 is awarded by lottery. The conditions for applying navistock in CZ are higher than the conditions for applying navistock in non-CZ, and navistock is more likely to be applied during CZ.

[Display of the number of digested games etc. when there is a setting change]
A time chart showing the transition of the number-of-digested game display etc. when there is a setting change will be described with reference to FIG. FIG. 9 is a time chart showing the transition of the number-of-digested games display etc. when there is a setting change. In FIG. 9, the transition of the number of digested games displayed on the liquid crystal display 51, the number of digested games stored in the RAM 41c, and the failure point stored in the RAM 41c will be described. Power interruptions occurring at times t2 and t4 are interruptions due to blackouts (such as momentary interruptions) during the business hours of the game arcade, and employees etc. during the non-business hours of the game arcade. It is assumed that the power interruption will occur by cutting.

  In FIG. 9, the horizontal axis indicates time t. Here, “on” of the “setting change process” indicates that the setting change is performed by the setting change process. "On" of "AT winning" indicates that an AT lottery has been executed and an AT has been won. "On" of "power" indicates that the slot machine 1 is supplied with power, and "off" indicates that the slot machine 1 is not supplied with power.

  Here, the time until t4 is the business hours of the game arcade, and the time from t4 to t5 is the non-business hours after the store is closed. After time t5, it is the business hours of the next day. For example, when the business hours are from 10:00 am to 11:00 pm, time t4 is 11 pm, which is the business closing time of the day, and time t5 is 10 am, which is the business start time of the next day. As an example of normal operation, it is assumed that the power of the slot machine 1 is turned off at the end of business hours, and the power of the slot machine 1 is turned on at the start of business hours.

  Before time t1, it is assumed that the control is performed by the AT. The control to the AT ends, and at time t1, the gaming state shifts to the non-AT state. At this time, the number of digested games stored in the RAM 41 c is “0”. The number-of-digestions game number display displayed on the liquid crystal display 51 is also "0G". At this time, the failure point is also stored in the RAM 41 c as 0.

At time t2, it is assumed that 586 games have been consumed in the non-AT state. At this time, the number of digested games stored in the RAM 41c is "586". Further, the display of the number of digested games displayed on the liquid crystal display 51 is also "586 G". Further, it is assumed that two non-CZ winning results are obtained in the CZ lottery in a period from time t1 to t2. At this time, the failure point at this time is updated from 0 to 2 and stored in the RAM 41 c. Further, by accumulating the failure points, a suggestion effect is performed in which a part of the screen of the liquid crystal display 51 is displayed as if it were cracked. When the failure point is 1, part of the screen is displayed as if it were cracked. When the failure point is changed from 1 to 2, the range in which the screen appears to be cracked further increases.

  At time t2, it is assumed that a momentary interruption due to a power failure occurs in the business hours. The power supply of the slot machine is turned off by the power failure to cause a power failure, and the power of the slot machine is turned on by recovering from the power failure at time t3 thereafter.

  At time t3, the number-of-digested-games display (the liquid crystal display 51), the number-of-digested games (RAM 41c), and the failure point (RAM 41c) all maintain numerical values before the power failure occurs.

  At time t3 to t4, it is assumed that the game is further consumed up to 726 games in the non-AT state. At this time, the number of digested games stored in the RAM 41 c is “726”. In addition, the display of the number of digested games displayed on the liquid crystal display 51 is also “726G”. Further, it is assumed that one more non-CZ winning result is obtained in the CZ lottery in a period from time t3 to time t4. At this time, the failure point is updated from 2 to 3 and stored in the RAM 41 c. Accumulation of failure points provides a suggestive effect that the range in which the screen appears to be cracked is further broadened.

  Time t4 shows that a power failure occurs when an employee etc. turns off the power of the slot machine 1 during the non-business hours. When the business is finished at time t4, the power is turned off, and the power of the slot machine 1 is turned on at time t5 after time Ts to recover from the power failure (that is, the power failure is at time Ts (for example, It has returned in the day-to-day state that occurs over 4 am).

  Although the number display of the number of digested games displayed on the liquid crystal display 51 at the time t4 (when business hours end) when the power failure occurs is “726 G”, the time t6 (after opening of business hours the next day) ) Is displayed as "0G".

  The number of digested games stored in the RAM 41c is initialized by changing the setting and becomes zero. Furthermore, random numbers are acquired from the numerical values in the range of 1 to 256 in the subsequent processing. Here, it is assumed that 115 is acquired. As a result, the number of digested games in the RAM 41c is rewritten to 115.

  Since the failure point is data that is not initialized by the setting change, it is still maintained at “3”. When returning from power failure due to crossing over the sun, the suggestion effect that suggests the accumulation of failure points is not executed for a specific period (20 games).

  At time t6 to t7, it is assumed that 885 games are further consumed while remaining in the non-AT state, and the number of digested games stored in the RAM 41c reaches "1000". However, since the display of the number of digested games displayed on the liquid crystal display 51 starts from “0 G”, “885 G” is displayed by performing 885 game digestion. Further, it is assumed that one more non-CZ winning result is obtained in the CZ lottery in a period from time t6 to time t7. At this time, the failure point at this time is updated from 3 to 4 and stored in the RAM 41 c. Accumulation of failure points provides a suggestive effect that the range in which the screen appears to be cracked is further broadened.

At time t7, the AT is won when the number of digested games stored in the RAM 41c reaches "1000", that is, the "ceiling". At this time, as shown in FIG.
A navistock in the range of ̃4 is given. By winning the AT, the number-of-digested-games display (the liquid crystal display 51), the number-of-digested games (RAM 41c), and the failure point (RAM 41c) are all reset to 0. By the fact that the failure point is 0, there is no suggestion effect that suggests accumulation of failure points.

  Here, the time Ts is set to a non-business hours (for example, 4 am) in the present embodiment. Time Ts is set to a time zone in which the slot machine 1 is powered off during non-business hours. By doing this, when a momentary interruption occurs in the business hours, it is possible to uniformly return the display of the number of digested games as "0 G" at the start of business hours (time t4). .

[Display of the number of digested games etc. when there is no setting change]
A time chart showing the transition of the number-of-digestions game display etc. when there is no setting change will be described with reference to FIG. FIG. 10 is a time chart showing transition of the number-of-digested games display etc. when there is no setting change. Hereinafter, the description of the same parts as those in FIG. 9 will be omitted.

  In FIG. 10, the horizontal axis indicates time t. In FIG. 10, unlike in FIG. 9, the setting is not changed at time t5 which is the business start time of the next day. In the description of FIG. 10, the description up to the time t5 is the same as the description of FIG.

  Although the number display of the number of digested games displayed on the liquid crystal display 51 at the time t4 (when the business hours end) when the power failure occurs is "726 G", at the time t5 (when the business hours start the next day) Is displayed as "0G" as in FIG. Further, since the setting change process has not been performed, the number of digested games stored in the RAM 41 c is still maintained at “726”. Also, the failure point is maintained at "3". When returning from power failure due to crossing over the sun, the suggestion effect that suggests the accumulation of failure points is not executed for a specific period (20 games).

  At time t5 to t6, it is assumed that 274 games are further digested while remaining in the non-AT state, and the number of digested games stored in the RAM 41c reaches "1000". However, since the display of the number of digested games displayed on the liquid crystal display 51 starts from "0G", "274G" is displayed by digesting 274 games. In addition, it is assumed that one more non-CZ winning result is obtained in the AT lottery in a period from time t5 to t6. At this time, the failure point at this time is updated from 3 to 4 and stored in the RAM 41 c. Accumulation of failure points provides a suggestive effect that the range in which the screen appears to be cracked is further broadened.

  At time t7, when the number of digested games stored in the RAM 41c reaches "1000", that is, "ceiling", the AT is won. At this time, as shown in FIG. 8, the navistock in the range of 1 to 4 is given by lottery. By winning the AT, the number-of-digested-games display (the liquid crystal display 51), the number-of-digested games (RAM 41c), and the failure point (RAM 41c) are all reset to 0. By the fact that the failure point is 0, there is no suggestion effect that suggests accumulation of failure points.

[Main effects obtained by the embodiment]
Next, main configurations and effects obtained by the above-described embodiment will be described.

In the present embodiment, when the slot machine 1 recovers from power interruption, as shown at time t6 in FIG. 9, when the set value is changed, the number of digested games stored in the RAM 41c corresponds to the random number value. Replaces the value 115. Therefore, when the setting value is changed, it is possible to prevent the interest of the game from being lowered by replacing the number of digested games with the initial value 0 each time. Furthermore, as shown at time t3 in FIG. 9 and time t3 and time t5 in FIG. 10, when the slot machine 1 recovers from power failure, the number of digested games is maintained when the set value is not changed, As shown at time t6 of 9, when the set value is changed, the number of digested games stored in the RAM 41c is replaced with the value 115 corresponding to the random value. For this reason, when the set value is changed, the difference between the number of digested games is reduced between when the set value is changed and when the set value is not changed, as compared with the case where the number of digested games changes to the initial value 0. be able to. Therefore, even when the setting value is changed, the possibility that the setting value is changed with the number of digested games as a clue is low.

  Further, as shown in FIG. 8, the AT is won when the number of digested games reaches 1000 games (ceiling), and the number of navi stock of 1 to 4 is given by lottery, so the interest is improved.

  In addition, when it is determined by lottery whether or not to win the AT when the number of digested games reaches 1000 games, whether or not the AT is won in the AT lottery performed when the number of digested games reaches 1000 games. Since the number of digested games is zero regardless of the number, it is easy for the player to understand that the number of digested games is accumulated for 1000 games again.

  Also, when returning from the power-off, as shown at time t5 in FIG. 10, the number-of-digested games display becomes 0 game, and the number of digested games is updated from 726 before power-off, while the number-of-digested games display is Updated from 0. For this reason, when a plurality of slot machines recover from the power failure simultaneously, all slot machines display 0 game which is the initial value, so that there is no difference in the display for each slot machine. it can.

  Further, as shown at time t6 in FIG. 9, the failure point is maintained at 3 even if the setting change processing is executed. Further, the liquid crystal display 51 displays a suggestion based on the accumulation of failure points. Specifically, when failure points are accumulated, a part of the screen is displayed as if it were cracked. The more points that are accumulated, the wider the range where the screen appears to be cracked. As shown after time t5 in FIG. 9 and after time t5 in FIG. 10, the player does not perform suggestion effects that suggest accumulation of failure points during the specific period (20 games), so the player performs effects after power failure return It is possible to make it impossible to distinguish the difference in situation.

  Further, as shown at time t6 in FIG. 9, when the slot machine 1 recovers from power failure, when the setting is changed, the stored number of digested games is substituted with the random number value 115, but random The maximum value of the numbers is smaller than 1000, which is the ceiling. For this reason, it is possible to prevent the player from generating an advantageous situation when the number of digested games suddenly reaches the ceiling (1000 games).

  Also, in the AT lottery process, the CZ lottery process, and the freeze lottery process, since the random number value is acquired by the same process as Sf 4 shown in FIG. 6, the processing burden of random number value acquisition after power failure recovery can be reduced. .

  In addition, since a random number value is acquired by the process of Sf 4 as shown in FIG. 6 after a predetermined period after being controlled to the setting change state, random number value generation processing may be performed at a timing related to the setting change state. it can.

[Modification]
As mentioned above, although the main embodiment in this invention was described, this invention is not limited to said embodiment, A various deformation | transformation and application are possible. Hereinafter, modified examples of the above-described embodiment applicable to the present invention will be described.

[About setting change processing]
A modification of the setting change process performed by the main control unit 41 will be described with reference to FIG. FIG. 11 is a flowchart showing a modification of the control content of the setting change process executed by the main control unit 41.

  The main control unit 41 transmits, to the sub control unit 91, a setting start command that can specify transition to the setting change state (Sg1). Thereafter, the main control unit 41 shifts to the setting change state (Sg2).

  The main control unit 41 performs an initialization process (Sg3). Specifically, the main control unit 41 clears the payout work excluding bonus points and bonus information.

  The main control unit 41 reads the current setting value from the RAM 41c, converts the read setting value into a display value (Sg4), and displays the converted display value on the setting value display 24 (Sg5). After that, the main control unit 41 determines whether the setting switch has been operated by the store clerk (Sg6). When determining that the setting switch has been operated within the predetermined period (YES in Sg7), the main control unit 41 updates the display value by 1 (Sg7), and displays the updated display value on the setting value display 24 ( Sg 5).

  On the other hand, when determining that the setting switch has not been operated within the predetermined period (NO in Sg6), the main control unit 41 determines whether the start switch 7 has been operated (Sg8). When the main control unit 41 determines that the start switch 7 has not been operated within the predetermined period (NO in Sg 8), the process returns to Sg 6.

  On the other hand, when the main control unit 41 determines that the start switch 7 has been operated within the predetermined period (YES in Sg 8), the main control unit 41 converts the display value displayed on the setting value display 24 into setting values and stores them in the RAM 41c. (Sg 9).

  Next, the main control unit 41 determines whether the setting key switch 37 is in the off state (Sg10). If the main control unit 41 does not determine that the setting key switch 37 is in the off state (the setting key switch 37 is in the on state) (NO in Sg10), the process returns to Sg10. On the other hand, when determining that the setting key switch 37 is in the off state (YES in Sg10), the main control unit 41 proceeds to the process of Sg11.

  The main control unit 41 acquires random number values in the range of 1 to 256 based on the random number clock of the random number clock generation circuit 43 (Sg11), and sets the acquired random number as the number of digested games (Sg12).

  Next, the main control unit 41 transmits, to the sub control unit 91, a setting end command that can specify that the setting change state is ended (Sg13). After that, the main control unit 41 ends the setting change state (Sg14), and ends the setting change process.

  As described above, as shown in FIG. 11, when an operation to turn off the setting key switch 37 is performed in Sg10 after being controlled to the setting change state, a random number value is acquired by the process of Sg11 The generation process of the random value can be performed at the timing related to the setting change state.

[On the grant of Navistock]
In the present embodiment, as shown in FIG. 8, when the number of digested games reaches 1000 and when the number of failure points reaches 5 points, a lottery for giving a navistock is performed. However, the present invention is not limited to this, and even when a specific lottery target combination is won, a lottery relating to the provision of navistock may be performed. For example, when a specific lottery target combination such as watermelon and cherry is won, a lottery is performed to determine whether or not to give the navistock. In the case of winning the navistock, as shown in FIG. 8, the navistock number of 1 to 4 is given by lottery. The assigned probability of the navistock and the expected value of the navistock number to be assigned may be changed according to the lottery target combination. For example, when a cherry is won, the navistock winning probability may be made higher than when a watermelon is won, and the expected value of the number of navistocks given may be made higher. Also, at this time, failure points may not be awarded when the player does not win in the CZ lottery, but may be granted failure points when the player does not win in the AT lottery. Further, the number of ceiling games is not limited to 1000 games, and may be any number of games. For example, there may be 100 games, 77 games or 111 games, which are the number of eyes.

[Determination of Crossing Day]
In the present embodiment, as shown in FIG. 5, when power failure occurs, when the power recovery time is after AM 4:00, initialization flag 2 is turned on, and the occurrence of day crossing is generated. It is judged. However, the present invention is not limited to this. When a predetermined time (for example, 6 hours) has elapsed since the power was turned off, the initialization flag 2 may be turned on, and it may be determined that the day crossing has occurred.

[About the number of digested games]
In the present embodiment, as shown in FIG. 6, when the setting change process is performed, the stored value (the number of digested games) stored in the RAM 41c is erased and the initial value (0) is substituted. The stored value (number of digested games) is changed to a random value. However, the present invention is not limited to this, and the main control unit 41 may change the accumulated value (the number of digested games) to a random number without deleting the accumulated value (the number of digested games) stored in the RAM 41c.

  Further, in the present embodiment, the number of digested games is stored in the non-AT state (the state is not controlled by the AT and includes the non-CZ state and the CZ state). However, the present invention is not limited to this, and the number of digested games may be accumulated in the normal section. That is, it may be made to accumulate in the state except the AT state and the CZ state.

[On a variation of slot machine]
Although the slot machine which pays out the game medium to the player's hand according to the occurrence of the prize has been described as the above embodiment, the game medium is enclosed and the game medium is paid out to the player's hand according to the occurrence of the prize. Alternatively, an enclosed type slot machine may be adopted which adds the game points (scores) without. The base and the drum can be distributed, and the base is common and only the base or the base and the drum are called game machines. In addition, it is a slot machine provided with a game area capable of playing a game ball and playing a game, and setting of the number of bets according to the game ball passing through a predetermined area provided in the game area. May be

[About benefits]
In the above-described example, the benefits are exemplified by values that directly affect the payout rates of medals and pachinko balls, such as bonus winning, AT winning, navi stock number, CZ winning, and the like. However, the benefit may be a value that improves the degree of advantage to the player, for example, a value that does not directly affect the payout rate of medals.

Specifically, when the high probability state in which the AT wins at a higher probability than in the normal time is provided in the AT lottery, execution of the probability suggestion effect for suggesting whether or not the current state is the high probability state The execution of the premiere effect (such as the appearance of a special character, the execution of a special bonus during the next generated bonus, the execution of a special bonus, etc.) with the voice on the liquid crystal display 51, the execution of the setting value suggestion effect for suggesting the set value. A point number that can be exchanged for the service defined in the gaming arcade in which the slot machine 1 is installed by collecting a fixed number, liquid crystal display of a two-dimensional code capable of downloading privilege images and privilege information at a predetermined website The display unit 51 may display the information.

  Moreover, although the navi stock number was illustrated as an example of a privilege, it is not restricted to this as a privilege about AT, the number of navi presentation executable possible frequency which can perform nabi production is determined, and it is the number of navi production executable possible number concerned When controlling to AT until the navi effect is executed, the navi effect executable number of times may be a privilege.

  Further, for example, in the case where the upper limit awarding amount is determined and the AT is controlled until the granted gaming value (the number of medals paid out) reaches the decided upper limit awarding amount, the upper limit awarding amount may be a privilege. Also, when a predetermined AT start condition is satisfied, the control is performed by the AT until a predetermined AT end condition is satisfied, and the continuation lottery is performed to determine whether the AT is to be continued when the AT end condition is satisfied. The continuation probability determined to continue in the lottery may be used as a benefit.

[About advantageous conditions]
In the above-described example, as the advantageous state, the slot machine has exemplified the big bonus (BB) or AT in which the probability of winning a small winning combination is higher than that in the predetermined state, but in the advantageous state for the player The present invention is not limited to this, and an example of a slot machine will be described below.

  The advantageous state is, for example, regular bonus (RB) or replay time (RT) in which the probability of winning a predetermined winning combination is high, concentration state of small combination, or retractable range of at least one reel is more than usual. Challenge time (CT) in which the occurrence of all small winning combination is permitted in each game as it becomes narrower, the operation procedure for winning the small winning combination instead of changing the winning probability of the winning combination etc. For example, it may be a pseudo bonus to be notified over a period (for example, until 50 games are consumed). In addition, the probability of being controlled to these advantageous states may be a high probability, or the probability of being controlled to a freeze state is a high probability, the number of games such as the number of navigation stock is a high probability An advantageous state of an aspect different from the above embodiment may be set, such as a state in which the game is added or a state in which the number of AT-added games is easily increased. In addition, the player has an advantage indirectly for the player, such as a condition for obtaining benefits on the communication network, or a condition in which the probability of fulfilling conditions for executing effects with a sense of premium (freeze effect, premium effect, etc.) is high. It may be a state in which the special benefits or the interest of the game is improved. Further, the permission determining means for determining whether or not to shift to the advantageous state is not limited to the internal lottery process, and may be a means for determining regardless of the winning combination.

  In addition, the advantageous state is, for example, “probability of being awarded”, and “when it is determined that a privilege is to be awarded, in a privilege giving lottery that determines whether or not to give a privilege. At least one of “value of benefit (or expected value of amount of benefit)” may be higher than a normal state (a state different from the advantageous state). Further, the advantageous state may be that the number of execution triggers of the privilege giving lottery is larger than that in the normal state. Further, the advantageous state may be a state in which the number of necessary digest games that need to be digested for giving a benefit is smaller than that in the normal state.

For example, in the case where the bonus is the navistock number, the advantageous state is “the AT winning probability in the AT lottery” and “navier awarded when the AT is won in the AT lottery” than in the normal state. At least one of the "stock value" may be higher than normal. Further, the advantageous state may be that the number of execution triggers of the AT lottery is larger than that in the normal state. For example, when the execution opportunity of the AT lottery in the normal state is the first winning combination and the second winning combination, the execution opportunity of the AT lottery in the advantageous state is the first winning combination and the second winning combination. In addition to, the third part may be elected.

[About production and notification]
In the example described above, an example in which presentation and notification are performed using the liquid crystal display 51 has been described. For example, the speakers 53 and 54, a back lamp disposed on the back side (inner side) of the reel (reel LED 55 of the above embodiment ), A transmissive liquid crystal display disposed on the front side of the reel (a liquid crystal display configured to allow viewing of the reel), a lamp or LED attached to the front door 1b, etc., vibration of the stop switch, and around the stop switch The effect may be performed by means different from the above embodiment, such as air blowing from the air or change in temperature of the stop switch.

[About AT]
Although the example in which the main control unit 41 executes the control related to the AT has been described in the example of the slot machine, the control related to the AT executed by the main control unit 41 includes the execution of AT lottery. The AT lottery may include determination of winning or not winning the AT lottery, determination of whether or not to stock the navi stock number, determination of the navi stock number, an additional lottery of the navi stock number, and the like. Moreover, control of the high probability state of AT lottery is mentioned as control concerning AT. In the control of the high probability state of the AT lottery, the control that the winning probability of the AT lottery becomes the high probability, the control to shorten the period until the AT is controlled according to the result of the internal lottery, the winning probability of the additional lottery and the game It includes control to give priority to the number.

  Moreover, control which sets a precursor period as control concerning AT is mentioned. The control for setting the precursor period includes control to execute, for example, effects of 0 to 32 games in the precursor period before the start of the AT.

  Moreover, control which gives a penalty is mentioned as control which concerns on AT. The control for giving a penalty includes the determination of the content of the penalty and the determination or setting of the penalty period. Further, as the control related to the AT, the main control unit 41 may perform lighting control of a lamp or an LED indicating that the AT is in progress.

  Further, as the control related to the AT, the main control unit 41 may perform lighting control of a lamp or an LED for executing a navigation effect. Furthermore, the sub control unit 91 may execute navigation effects in conjunction with the main control unit 41 performing navigation effects. Furthermore, when improving the lottery probability, for example, when controlling to a high probability state of AT lottery, the main control unit 41 notifies that by lighting control of a lamp or an LED (for example, game assistance indicator 12 etc.) You may do so.

  More specifically, the main control unit 41 may notify that control is made to the high probability state of the AT lottery by executing the navigation effect a predetermined number of times by the game assistance indicator 12. Alternatively, the main control unit 41 may notify the sub control unit 91 that the control should be performed in the high probability state of the AT lottery by executing the navigation effect a predetermined number of times.

When the main control unit 41 executes the control related to the AT, it is preferable to execute the processing of the main control unit 41 by the control unit subordinate to the main control unit 41 and subordinate to the main control unit 41. . For example, a control unit provided on a board other than the game control board may execute stop control of the reels, and the main control unit 41 may transfer an operation signal of the stop switch to the control section. As described above, by causing the control unit on the lower side to perform control of the main control unit 41, it is possible to prevent the capacity shortage of the ROM 41b and the RAM 41c when performing control related to AT and the processing capacity shortage of the main CPU 41a.

  Further, in the embodiment described above, the main control unit 41 executes the control related to the AT described above, but the sub control unit 91 may execute it. The sub control unit 91 performs AT lottery processing and additional lottery processing based on, for example, an internal winning command from the main control unit 41, and executes processing for controlling the AT or navigation effect according to the result. Processing may be performed.

[About the setting change status and the setting confirmation status]
The setting change state may be shifted to the setting change state on the condition of “power on” + “setting key switch on” + “front door open detection”. This makes it possible to prevent an unauthorized setting change in a state where the front door is not opened. In addition, once the setting change state is entered, the setting change state is maintained regardless of the open / close state of the front door until the end condition (the set key switch is turned off after setting value determination) for ending the setting change state is satisfied. You may do it. As a result, even if the front door is closed during the setting change state, the setting change state is not ended, so it is possible to prevent the trouble of causing transition to the setting change state again.

  The setting confirmation state may be shifted to the setting confirmation state under the condition of “setting key switch on” + “front door opening detection”. Thereby, it is possible to prevent an incorrect setting confirmation in a state where the front door is not opened. In addition, once the setting confirmation state is entered, the setting confirmation state is maintained regardless of the open / close state of the front door until the end condition (setting key switch is off operation) for ending the setting confirmation state is satisfied. It is also good. As a result, even if the front door is closed during the setting confirmation state, the setting confirmation state is not ended, so it is possible to prevent the trouble of causing transition to the setting confirmation state again.
