Description

  The present invention includes a variable display unit capable of variably displaying a plurality of types of identification information each identifiable. After the variable display unit is variably displayed, the display result is obtained by stopping the variable display of the variable display unit. The present invention relates to a slot machine that can derive and win according to the display result.

  A slot machine generally includes a variable display section having a plurality of (usually three) reels on which a plurality of types of symbols as identification information are drawn on the outer periphery. Each reel has a start lever. Start rotation by operating. When the player operates a stop button provided corresponding to each reel, the rotation is stopped within a predetermined maximum delay time from the operation timing. A winning is generated according to the display result derived when the rotation of all reels is stopped.

  The types of winning combinations include small roles, special roles, and replaying roles. Here, in the winning of a small role, the player can obtain a profit that a predetermined number of medals are paid out for each type of small role. In the special role winning, the player can obtain a profit that the next game is shifted to a gaming state advantageous to the player, such as a regular bonus or a big bonus. In the winning of the re-gamer, it is possible to obtain a profit that the next game can be performed without consuming new medals for setting the number of bets.

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

Japanese Patent Application Laid-Open No. 2006-119991

  In the slot machine disclosed in Patent Document 1, since the accumulated value is replaced with the initial value every time the advantage is changed, the interest of the game is lowered. Further, in this slot machine, there is a possibility that the player may recognize that the advantage has been changed based on the fact that the accumulated value has changed to the initial value.

  The present invention has been conceived in view of such circumstances, and its purpose is to allow a player to detect a change in advantage without reducing the interest of the game due to a change in the accumulated value at the time of changing the advantage. It is to provide a slot machine that is unlikely to be.

(1) Provided with a variable display unit capable of variably displaying a plurality of types of identification information each capable of being identified,
In the slot machine (for example, slot machine 1) in which a winning result can be generated according to the display result after the variable display portion is variably displayed, the display result is derived by stopping the variable display of the variable display portion.
An advantage changing means (for example, a setting changing process executed by the main control unit 41 shown in FIGS. 6 and 11) for changing an advantage (for example, a set value) for the player;
Processing of Sf4 based on random number generation means (for example, a random number clock generation circuit 43 executed by the main control unit 41 shown in FIG. 6) for generating a random value (for example, a numerical value acquired randomly in the range of 1 to 256) )When,
Storage means (for example, RAM 91c) for storing an accumulated value (for example, the number of digested games) accumulated as the game progresses,
The accumulated value stored in the storage means reaches 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 the figure, the number of digested games will be 0 after reaching 1000 games)
In the case where the slot machine returns from the power interruption, when the advantage is not changed by the advantage changing means, the accumulated value stored in the storage means is maintained at the accumulated value before the power interruption (for example, As shown at time t3 in FIG. 9 and time t3 and time t5 in FIG. 10, if the setting is not changed when returning from power interruption, the number of digested games does not change), the advantage is changed by the advantage changing means. Is replaced with a value corresponding to the random number value in place of the stored value stored in the storage means (for example, when the setting is changed when power is restored from power interruption as shown at time t6 in FIG. 9). Is a process of Sf5 shown in FIGS. 7A and 6 in which the random number 115 is substituted for the number of digest games.

  According to such a configuration, when the slot machine returns from the power interruption, the accumulated value is replaced with a value corresponding to the random number value when the advantage is changed. For this reason, it is possible to prevent the interest of the game from deteriorating due to the accumulated value replacing the initial value every time the advantage is changed. Further, when the slot machine returns from the power interruption, the accumulated value is maintained when the advantage is not changed, while the accumulated value is replaced with a value corresponding to the random number value when the advantage is changed. For this reason, the difference between the accumulated value when the advantage is changed and when the advantage is not changed can be made smaller than when the accumulated value is replaced with the initial value when the advantage is changed. . Therefore, even if the advantage is changed, there is a low possibility that the advantage is recognized based on the accumulated value.

(2) In the slot machine of (1) above,
A privilege granting means for granting a privilege (for example, navigation stock) (for example, a process in which the main control unit 41 gives navigation stock) is further provided,
The privilege granting unit grants a privilege when the accumulated value stored in the storage unit reaches the predetermined value (for example, when the number of digest games reaches 1000 games (ceiling) as shown in FIG. 8). 1 to 4 navigation stocks will be given to the user by AT lottery).

  According to such a configuration, since the privilege is granted when the accumulated value reaches the predetermined value, the interest is improved.

(3) In the slot machine of (1) above,
A bonus lottery means (for example, a process in which the main control unit 41 performs an AT lottery) for determining whether or not to grant a privilege (for example, navigation stock) by lottery,
The privilege lottery means determines by lottery whether or not a privilege is granted when the accumulated value stored in the storage means reaches the predetermined value (for example, when the number of digest games reaches 1000 games). The main control unit 41 performs an AT lottery),
The accumulated value stored in the storage means becomes the initial value when the predetermined value is reached regardless of whether or not the bonus is determined by the bonus lottery means (for example, the number of digest games is 1000 games). In the AT lottery that is performed when arriving at is reached, the number of digest games is set to 0 regardless of whether or not the AT is won).

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

(4) In the slot machine of any of (1) to (3) above,
Further comprising 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 accumulated value stored in the storage means when the slot machine returns from the power interruption (for example, as shown at time t5 in FIG. 10). , The digest game number display will be 0 game when returning from power interruption)
When the slot machine returns from the power interruption, the stored value stored in the storage means is updated as the game progresses (for example, as shown at time t5 in FIG. 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). In addition, the display of the number of digested games is updated from 0 when returning from power interruption).

  According to such a configuration, when the slot machine returns from the power interruption, a value corresponding to the initial value is displayed regardless of the accumulated value, and when the slot machine returns from the power interruption, the accumulated 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 multiple slot machines are recovered from power interruption all at once, these slot machines will display values corresponding to the initial values, so that there is no difference in the display for each slot machine. be able to.

(5) In the slot machine of any of (1) to (4) above,
The storage means stores a specific value (for example, a failure point) that is different from the accumulated value and is accumulated as the game progresses (for example, as shown in FIGS. 9 and 10), RAM41c)
Even when the advantage is changed by the advantage changing means, the specific value stored in the storage means is maintained at the specific value before the power interruption (for example, as shown at time t6 in FIG. 9). , Even if the setting change process is executed, the failure point remains 3)
If the slot machine accumulates failure points in the liquid crystal display 51 when the suggestion effect means (for example, the sub-control unit 91 accumulates failure points) suggesting the accumulation status of the specific value stored in the storage means, Part of the screen appears to be cracked and the screen appears to crack according to the accumulation of failure points)
The suggestion effect means does not execute the suggestion effect in a specific period (for example, 20G) after the slot machine returns from the power interruption (for example, a specific period after time t5 in FIG. 9 and a time period after time t5 in FIG. 10). Does not provide a suggestion that suggests the accumulation of failure points).

  According to such a configuration, the suggestive effect that suggests the accumulation state of the specific value is not executed in the specific period after the slot machine returns from the power interruption. For this reason, it is possible to prevent the player from discriminating the difference in the production situation after the return from power interruption.

(6) In the slot machine of any of (1) to (5) above,
In the case where the slot machine returns from the power interruption, when the advantage is changed by the advantage change means, the random number value is substituted as it is instead of the accumulated value stored in the storage means (for example, FIG. 9). As shown at time t6, the random number 115 is directly substituted for the number of digest 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 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. For this reason, it is possible to prevent the situation that is advantageous to the player from occurring because the accumulated value suddenly reaches the predetermined value.

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

  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 for obtaining the random value after the interruption of power interruption.

(8) In the slot machine of any of (1) to (7) above,
Based on the operation of the operation means (for example, the setting key switch 37), the advantage change control means (for example, as shown in FIG. 6) that can be controlled to the advantage change state for changing the advantage by the advantage change means. 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, and
The random value generation means generates the random value after a predetermined period of time after being controlled to the advantage change state (for example, generates a random value by the process of Sf4 shown in FIG. 6).

  According to such a configuration, since the random number value is generated after a predetermined period of time after being controlled to the advantage changing state, the random value generation process can be performed at a timing related to the advantage changing state.

(9) In the slot machine of any of (1) to (7) above,
Based on the operation of the operation means (for example, the setting key switch 37), the advantage change control means (for example, as shown in FIG. 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, and
The random number generation means generates the random number value when an operation for ending control to the advantage change state is performed by the operation means after being controlled to the advantage change state (for example, When a setting key switch 37 is turned off 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 an operation for ending the control to the advantage change state is performed by the operating means after being controlled to the advantage change state, the advantage change state Random value generation processing can be performed at a timing related to.

  A mode for carrying out a slot machine according to the present invention will be described below based on examples. In the following embodiments, an example in which the present invention is applied to a slot machine will be described.

[Configuration of slot machine]
FIG. 1A is a front view of the slot machine according to the present embodiment, and FIG. 1B is a diagram illustrating an example of a main internal configuration of the slot machine 1. As shown in FIG. 1A, the slot machine 1 includes a liquid crystal display 51 provided on the front door 1b, and reels 2L, 2C, and 2R arranged in parallel inside the housing 1a through the see-through window 3. Visible. As shown in FIG. 2, on each reel, a plurality of types 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 credit range stored as the gaming value (number of medals) owned by the player as an example of the operating means. The MAXBET switch 6 that is operated when setting a predetermined number of bets, the medal stored as credits, and the medals used for setting the bets are settled (medals for the setting of credits and bets) Used for the production, the settlement switch 10 operated when starting the game, the start switch 7 operated when starting the game, the stop switches 8L, 8C, 8R operated when stopping the rotation of the reels, respectively. For example, an effect switch 56 is provided.

  The front door 1b is provided with a game display unit 13 for notifying information related to a game as an example of a notification unit. The game display unit 13 includes a credit display 11 that displays the number of medals stored as credits, a game auxiliary display 12 that displays a medal payout number and an error code when an error occurs, and a set bet. 1BETLED14 for informing the number, 2BETLED15, 3BETLED16, insertion request LED 17 for informing that the medal can be inserted, start valid LED 18 for informing that the game can be started by operating the start switch 7, and replay A replaying LED 20 is provided to notify that the replay game after winning is in progress. The game display unit 13 is provided with an advantageous section notification lamp 19 for notifying that it is in an advantageous section described later by turning on the LED lamp.

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

  The winning line is a line for determining whether the combination of symbols displayed on the see-through window 3 of the reels 2L, 2C, 2R is a winning symbol combination. In the present embodiment, an example in which only one winning line LN is provided will be described. However, a plurality of winning lines may be provided. In addition, invalid lines LM1 to LM4 are provided to make it easy to recognize that the combination of symbols constituting the winning line is aligned with the winning 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 display the symbols in a variable manner. When the stop switches 8L, 8C, 8R are operated, the corresponding reels are rotated. By stopping, three symbols are derived and displayed as display results on the upper, middle, and lower stages of the fluoroscopic window 3. When a combination of winning symbols stops on the winning line LN and a winning occurs, a predetermined number of medals are given to the player according to the winning and the credit is added or the credit reaches the upper limit (50). In this case, medals are paid out from the medal payout exit 9.

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

  The main control unit 41 is composed of a one-chip microcomputer, and includes a RAM 41c used as a work memory, and a main CPU 41a that performs control operations according to a program, and performs processing related to the progress of the game and a game control board. Each part of the control circuit mounted on 40 is controlled directly or indirectly. When the MAXBET 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 operations on these various switches based on detection signals from these various switches. From the main control unit 41, a control signal for 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 are turned on 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 that generates a drive power supply for electrical components. The power supply board 101 is supplied with AC 100V power from the outside, and a DC voltage necessary for driving the electrical components constituting the slot machine 1 is generated from the AC 100V power supply. The voltage generated by the power supply board 101 is supplied to the effect control board 90 connected via the game control board 40. The power supply board 101 is connected to a setting key switch 37 for performing a setting change process described later.

  Although not shown, the game control board 40 includes a power interruption detection circuit, a reset circuit, and an RTC (real time clock). The power interruption detection circuit monitors the power supply voltage supplied to the slot machine 1. The power interruption detection circuit is a circuit that outputs a voltage drop signal to the main control unit 41 when a voltage drop is detected (for example, whether or not the voltage drop has become equal to or lower than a predetermined voltage). The main control unit 41 includes an interrupt input terminal. When a voltage drop signal is input to the interrupt input terminal, an external interrupt is generated, and a power interruption interrupt process is performed according to the external interrupt. Run. Further, the main CPU 41a executes a timer interrupt process at regular time intervals (about 0.56 ms in this embodiment).

  The reset circuit outputs a reset signal to the main control unit 41 to activate 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. The reset circuit counts up without clearing the value of the reset counter 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 to restart the main control unit 41.

  The RTC measures and outputs the current time. The main control unit 41 acquires date / time information including the current date information and time information output by the RTC, and executes various processes based on the acquired date / 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 current “hour”, “minute”, and “second” information. The RTC stores the time measured in the storage area of the RAM 41c in the form of predetermined date information, and rewrites the date information in 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 is supplied from the backup power supply circuit when the power supply to the slot machine 1 is cut off (power interruption). It operates with a power source that operates. Therefore, the RTC can keep track of the current date and time even during power interruption. The RTC may be provided in the effect control board 90. In this case, the sub-control unit 91 acquires date / time information including the current date information and time information output by the RTC, and executes various processes based on the acquired date / time information. Further, the RTC stores the time measured in the storage area of the RAM 91c in the form of predetermined date information, and rewrites the date information in the time storage area for each unit update time. Other operations of the RTC included in the effect control board 90 are the same as the operations of the RTC included in 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, and includes a RAM 91c used as a work memory and a sub CPU 91a that performs a control operation according to a program. And controlling 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 the operation 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 a control signal from the sub control unit 91. The speakers 53 and 54 output sound based on a control signal from the sub-control unit 91. Note that FIG. 1B is merely an example, and the slot machine 1 is provided with other configurations.

[Setting value]
In the slot machine 1 according to the present embodiment, the medal payout rate (the ratio between the total number of medals used for setting the number of bets and the total number of medals paid out by winning) changes according to the set value. Specifically, the medal payout rate is changed by using a winning probability corresponding to a set value in an internal lottery to be described later. The set value is composed of 6 levels of 1 to 6, for example, 6 is the highest payout rate, and the payout rate decreases as the value decreases in the order of 5, 4, 3, 2, 1. That is, from the point of view of the payout rate, when the set value is set to 6, the player has the highest advantage, and the advantage decreases step by step as the value decreases 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 41c of the main control unit 41 is displayed as a display value on the setting value display provided in the housing 1a of the slot machine 1. A transition is made to a setting change state in which a setting value can be changed by operating a reset / setting switch provided in the housing 1a of the slot machine 1. When the reset / setting switch is operated in the setting change state, the display value displayed on the setting value display is updated one by one (when further operation is performed from setting 6, the setting value is returned to setting 1). 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 41c of the main control unit 41, and the state shifts to a state in which the game can proceed.

  In order to confirm the set value, after the game is over, the setting key switch 37 may be turned on in a state where the number of bets is not set. When the setting key switch 37 is turned on in such a situation, the setting value read from the RAM 41c is displayed on the setting value display device, thereby shifting to a setting confirmation state in which the setting value can be confirmed. In the setting confirmation state, the game cannot be progressed, and by setting the setting key switch 37 to the off state, the setting confirmation state is ended and the state where the game can proceed is returned.

[Internal lottery]
When the start switch 7 is operated after setting the bet amount, an internal lottery is performed by the main control unit 41 for determining whether or not winning is allowed (internal lottery). For example, a random number circuit (not shown) included in the main control unit 41 updates determination values belonging to a predetermined range (1 to 65536) according to a predetermined update rule. The main control unit 41 extracts a determination value updated by the random number circuit when the start switch 7 is operated. If the extracted determination value corresponds to a determination value belonging to a predetermined range predetermined for each lottery target, the main control unit 41 determines that the corresponding lottery target is won. When a lottery target combination is won in the internal lottery, a winning combination winning flag included in the lottery target combination is set in a predetermined area of the RAM 41c. For example, when BB (bonus) is won, a BB winning flag is set. BB is a winning combination with a transition to an advantageous state of bonus. Each bonus is ended by paying out more than a predetermined number of medals. For example, a bonus controlled by winning / winning BB ends in a game in which the number of medals paid out during the bonus is 351 or more. When a strong cherry is won, a winning flag for the lower cherries and a winning flag for a single winning combination 1 are set. The winning flag of the BB is carried over until the winning BB wins, while the winning flag corresponding to a winning combination other than the BB is erased when the winning game ends regardless of whether or not a winning has occurred. .

[Normal section and advantageous section]
The game sections performed in the slot machine 1 include a normal section and an advantageous section. The advantageous section is a section having the performance related to the instruction function for instructing the player about the operation mode (push 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).

  AT is a notification state in which a navigation effect is executed that is controlled by the main control unit 41 and notifies the player of the operation mode (push order, operation timing) of the stop switches 8L, 8C, 8R. Specifically, the main control unit 41 executes an AT lottery regarding the granting of navigation stock which is the right to be controlled by the AT. For example, the main control unit 41 determines whether or not to provide navigation stock and the number of grants (number of navigation stocks) in the case of granting navigation stock by AT lottery. The number of navigation stocks 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 obtains a random number value from 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 give the navigation stock when the acquired random number value belongs within a predetermined winning range. Note that the decision to give navigation stock in the AT lottery is referred to as AT winning, and the fact that it is not decided to give navigation stock in the AT lottery is called non-AT winning.

  The main control unit 41 stores the number of AT games corresponding to the number of assigned navigation stocks in a predetermined area of the RAM 41c when the AT lottery is won. Then, the main control unit 41 controls the AT over the number of stored AT games. When the main control unit 41 wins a push order such as a push order bell or push order replay during the AT, the main control unit 41 stops the symbol combination corresponding to the selected push order and advantageous to the player on the winning line LN. The operation mode for this is notified by the navigation effect. Therefore, by controlling the AT, the player can easily increase the net number of medals. In addition, the operation procedure corresponding to the type of push order combination and the procedure notified by the navigation effect is referred to as a correct answer procedure. On the other hand, a procedure that does not correspond to the type of push order combination and 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 extra lottery during the AT. The extra lottery is a lottery for adding the number of navigation stocks to the number of navigation stocks already granted. The fact that it is decided to add Navistock in the extra lottery is also referred to as extra prize winning. When the winning combination is won, the number of assigned navigation stocks is added to the number of navigation stocks stored in the RAM 41c.

  CZ is in a state controlled to an advantageous section for the player. During CZ, the advantage level related to the control to the AT is higher than normal (during non-CZ). Specifically, during CZ, the probability of winning an AT is higher than during non-CZ, and the number of navigation stocks given when winning an AT increases. The main control unit 41 executes a CZ lottery regarding the provision of a CZ game that is a right to be controlled by the CZ. In the CZ lottery, the main control unit 41 obtains a random value from numerical values within a 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 whether or not to grant a CZ game (CZ winning) when the acquired random number value belongs within a predetermined range. Furthermore, the number of grants (CZ game count) when a CZ game is awarded is determined. The CZ lottery is executed by winning a specific lottery role (watermelon and cherry). If it is decided to give a CZ game in the CZ lottery, the control is made to the CZ state. On the other hand, if it is not decided to give a CZ game in the CZ lottery, a failure point described later is given. . The CZ may be advantageous to the player in that the navigation effect in which a winning in which the maximum payout number is obtained is generated is executed at least once, and the degree of advantage related to the control to the AT is the same as usual. Good. Of course, the CZ may be advantageous to the player in that the navigation effect in which a winning in which the maximum payout number is obtained is generated is executed at least once, and the degree of advantage regarding the control to the AT becomes higher than usual.

  Note that the number of CZs is not limited to one, and a plurality of types may be provided. In this case, in any CZ, the degree of advantage related to the control to the AT is higher than usual, but the degree of advantage may be varied depending on 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 winning determination command, a game 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 day span command are transmitted.

  The setting start command is a command that can specify the start of the setting change process executed 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 executed 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 object combination that has been won according to the result of the internal lottery belongs. The internal winning command is transmitted when the start switch 7 is operated and the game is started. By receiving the internal winning command, the sub-control unit 91 can specify the operation of the start switch 7 and the group to which the winning lottery combination belongs.

  The push order command is a command that can specify an operation procedure (correct procedure) for stopping a symbol combination that is advantageous to the player in accordance with the lottery target combination won in the internal lottery. The push order command is transmitted when the start switch 7 is operated and the game is started in the advantageous section. For example, during AT, a push order command that can identify the correct procedure is transmitted, and during non-AT, a push order command that can identify the correct procedure is not transmitted. For this reason, the sub-control unit 91 can identify the correct procedure by receiving the push order command during AT, but cannot identify the correct procedure during non-AT. During non-AT, a push order command that can specify a predetermined standard procedure (for example, the first left 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 whether the reel to be stopped is the left reel 2L, the middle reel 2C, or the right reel 2R, the area number of the corresponding reel stop operation position, the area number of the corresponding reel stop position, etc. It is a possible command. The reel stop command is transmitted each time stop control associated with a stop operation of each reel is performed. The sub-control unit 91 can specify that the stop switches 8L, 8C, 8R are operated by receiving the reel stop command.

  The winning determination command is a command that can specify the combination of symbols arranged on the winning line LN, the presence / absence of winning, the type of winning, the number of medals paid out at the time of winning, and the like. The winning determination command is transmitted after all reels are stopped and the winning determination is performed.

  The gaming state command is a command that can specify the gaming 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. In the present embodiment, the game state command includes the number of digested games that are the number of games accumulated in the non-AT state, and information that can specify the failure point.

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

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

  The day straddling command is a command that can specify whether or not a day is straddled from the time of occurrence of power interruption to the time of power interruption recovery when the power is restored from the power interruption. In the present embodiment, as shown in FIG. 9, the determination of day straddling is performed based on whether or not the power interruption has been recovered over time Ts (AM 4 o'clock). The date crossing command is transmitted when the initialization flag 2 is on in the startup process (main).

  The sub control unit 91 performs output control of various effect devices such as the liquid crystal display 51, the effect 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 a game process and controls one game. In the game process, first, a BET process for setting a bet amount and for adjusting a credit amount / betting amount is performed.

  When the start switch 7 is operated after setting the bet amount, an internal lottery process for determining whether or not winning is allowed (internal lottery) is performed.

  In the internal lottery process, after the internal lottery is performed, an internal lottery command setting process for setting a command corresponding to the result of the internal lottery is executed. The main control unit 41 reads the internal winning flag set by the internal lottery, and when one of the lottery target roles is won, sets the internal winning command for specifying the group to which the lottery target role belongs in the command queue. For example, when the main control unit 41 wins any of a left bell, a middle bell, and a right bell, which will be described later, the main control unit 41 transmits an internal winning command that can specify a group of push order bells to which these roles belong. Note that when no winning lottery is won, an internal winning command is set to identify a loss.

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

  On the other hand, the main control unit 41 sets, in the command queue, a push order command that can specify a predetermined standard procedure when not in AT or when the winning combination for navigation lottery is not won. Thereby, even if it is a case where fraud is performed in the sub-control part 91 side, the effect according to the group specified from an internal winning command can be performed, preventing a correct procedure from being specified.

  When the internal lottery process ends, a reel rotation process is performed. In the reel rotation process, after a predetermined time (for example, 4.1 seconds) has elapsed since the start of reel rotation in the previous game, the reels 2L, 2C, and 2R are started to rotate, and then the stop switches 8L and 8C. , 8R are activated, and the rotation of the reel is stopped according to the stop operation.

  In the reel rotation processing, when a predetermined freeze condition is satisfied, a freeze effect is executed that delays the progress of the game for a predetermined period (delaying the stop operation of each of the stop switches 8L, 8C, and 8R is delayed). After executing the freezing effect process for enabling, the stop switches 8L, 8C, 8R are validated to shift to the normal game. Based on the winning combination, the main control unit 41 executes a freeze lottery that determines whether to generate a freeze. In the freeze lottery, the main control unit 41 obtains a random number value from numerical values within a 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 perform freezing when the acquired random number value belongs to a predetermined winning range.

  When the reels 2L, 2C, 2R are stopped and the reel rotation process is completed, a winning determination process is performed for determining whether or not a winning has occurred based on the symbol combination on the winning line.

  When the winning determination process ends, a payout process is performed. In the payout process, medals are paid out or credits are added according to the occurrence of a prize, and various processes not related to the prize (for example, the process related to the bonus end control by counting the number of medals paid out in the bonus, and the winning without carryover) Flags (deletion of a winning combination such as a small combination / re-playing combination) are performed). In the game end process, a process for setting a game state in preparation for the next game is executed. Thereby, the game process for one game is completed, and the game process for the next one game is started.

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

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

  The main control unit 41 determines whether or not the power interruption flag is set (Sp3). When the power interruption flag is set (YES in Sp3), the main control unit 41 proceeds to a power interruption process (main).

  When the power interruption flag is not set (NO in Sp3), the main control unit 41 ends this routine.

[Power interruption (main)]
The power interruption process (main) executed by the main control unit 41 in the power interruption determination process (timer interrupt process (main)) will be described with reference to FIG. FIG. 3 is a flowchart showing the control contents of the power interruption process (main) executed by the main control unit 41 in the timer interrupt process (main).

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

  In order to be able to determine whether or not the RAM 41c is normal at the next start-up, the main control unit 41 calculates parity adjustment data so that the RAM parity of all storage areas of the RAM 41c becomes 0, and stores it in a predetermined area of the RAM 41c. Store (Sd2).

  The main control unit 41 prohibits RAM access (Sd3) and sets interrupt prohibition (Sd4). Thereafter, the main control unit 41 enters a loop process in which no process is performed. That is, when the voltage decreases as it is, the operation is stopped internally. Thereby, the operation | movement of the main control part 41 stops at the time of a power failure.

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

  As shown in FIG. 4, the main control unit 41 initializes a built-in device or the like (Sr1), and permits access to the RAM 41c (Sr2). The main control unit 41 calculates the RAM parity of all storage areas of the RAM 41c (Sr3), and determines whether or not the RAM parity is 0 (Sr4).

  Since the RAM parity is adjusted to 0 in advance in the power interruption process, the main control unit 41 has normal data stored in the RAM 41c if the RAM parity is 0 (YES in Sr4). 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), the main control unit 41 performs a predetermined initialization based on whether or not the setting key switch 37 is turned on, and the power interruption date and time and the double power date and time. An initialization determination process for determining whether or not the condition is satisfied is executed (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 set in the initialization determination process has been changed. 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 or not the initialization flag 2 is turned on (Sr9). The initialization flag 2 is a flag indicating whether or not the day spanning 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 the day spanning process (Sr10).

  In the day spanning process, the main control unit 41 transmits a day spanning command to the sub control unit 91. Specifically, a command is transmitted that makes it possible to specify that recovery from power interruption has occurred across time Ts (for example, at 4 AM).

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

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

[Initialization judgment processing]
With reference to FIG. 5, an initialization determination process executed by the main control unit 41 in the startup process (main) will be described. FIG. 5 is a flowchart showing the control content of the initialization determination process executed by the main control unit 41 in the startup process (main).

  When the power source of the slot machine 1 is switched from the off state to the on state, the main control unit 41 determines whether or not 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 (in the off state) (NO in St1), 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 41c ( St3). Since the date / time control process in the timer interruption process is not executed during power interruption, the date / time information stored in the update time storage area immediately after power recovery is substantially the same as the date / time information at power interruption. For this reason, at St3, the main control unit 41 acquires date / time information at the time of power recovery (that is, current) from the update time storage area of the RAM 41c after at least one date / time control process is executed after the power recovery.

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

  The main control unit 41 determines whether or not the power recovery time is after 4:00 AM (St5). When the power recovery time is after 4:00 AM (YES in St5), the main control unit 41 turns on the initialization flag 2 (St6) and ends this routine. On the other hand, if the power recovery time is not after AM4 (NO at St5), the main control unit 41 ends this routine.

[Digestion game number and digestion game number display]
Next, the relationship between the numerical value accumulated in the non-AT state (a state that is not controlled by the AT and includes the non-CZ state and the CZ state), power interruption, and setting change will be described. The numerical values accumulated in the normal game state include the number of digest games and failure points. Details will be described below.

  The number of digested games is an accumulated value accumulated as the game progresses in the non-AT state. The number of digest games is stored in a predetermined area of the RAM 41c. When the control state shifts from the AT state to the non-AT state, the number of digested games starts updating from 0 and increases by 1 every time one game is digested. When the number of digested games reaches 1000, navigation stock is given by AT lottery described later. When the number of digested games reaches 1000 (so-called ceiling game number), 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. The

  The number of digestion games can be changed when a power interruption occurs. In the present embodiment, the number of digested games is changed when power interruption is restored across AM4, which is a non-business time zone (day stride), and when 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. In the setting change process, the main control unit 41 obtains a random value from numerical values within a range of 1 to 256 generated by the random number clock generation circuit 43. Then, the main control unit 41 stores the acquired random number value in the RAM 41c instead of the number of digest games. In addition, even if it is between days, when the setting is not changed, the number of digest games is not changed, and the accumulated value before the power interruption is taken over. Even in the event of a power outage that occurs during business hours (for example, during a power outage such as a power outage), the number of digest games is not changed and the accumulated value before the power outage is taken over.

  In the digest game number display, the number of games based on the digest game number read from the RAM 41 c is displayed on the liquid crystal display 51. The display of the number of digested games is generated based on the number of digested games that can be specified from the game 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 the same value. However, as will be described below, when a power interruption occurs, the number of digested games may be different from the number of digested games displayed. For example, the digest game number display is initialized and “0G” is displayed when the power interruption is restored by straddling the day. On the other hand, as described above, the number of digested games is set to a random value in the range of 1 to 256 when power interruption occurs due to straddling and there is a setting change. On the other hand, if a power interruption due to day-to-day occurrence occurs and there is no setting change, the random number value before the power interruption is taken over.

  By doing as described above, in the state where the power interruption is restored by straddling the day (one morning in the start of business hours), all the digested game number displays of the plurality of slot machines installed in the hall are displayed as “0G”. Can be unified. As a result, inequalities do not occur in the player's selection of the best slot machine in the morning. For example, assume 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 is displayed as “998G”, the player will recognize that he will reach the ceiling in two more games and win the AT. However, as in this embodiment, in the morning in the morning immediately after the start of business, the accumulated value is displayed as “0G” so that inequalities due to player selection do not occur among players. In the case of a power failure recovery due to a power failure during business hours, it is highly possible that the players are the same before and after the power failure recovery, so the display is accumulated by initializing the display as “0 game” as described above. The player does not feel dissatisfied with the value being changed.

  In addition, in the power interruption recovery state by straddling the day (in the morning one at the start of business hours), if there is no setting change, the number of digest games stored in the RAM 41c is taken over as it is, and if there is a setting change, the RAM 41c A random value is assigned to the number of digested games stored. By doing so, it is difficult for the player to recognize whether or not the setting has been changed, and inequality does not occur when selecting a machine in the morning. For example, it is assumed that the number of digested games is already “960G” close to the ceiling immediately before the end of business hours on the previous day. A player who has confirmed this can play the 40 game game in the morning of the next day, and can reach the ceiling and win an AT. However, if the setting is changed and the number of digested games is reset to 0 after initialization, even if 40 games are played, the ceiling is not reached. In other words, the player recognizes that the setting has been changed simply by executing a game of 40 games. If the random number value is substituted for the number of digested games stored in the RAM 41c when the setting is changed as in the present embodiment, it is due to the setting change or the random value setting. However, it is difficult for the player to recognize that the setting has been changed.

[Failure points and suggestions]
The failure point is an accumulated value 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 1 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 point reaches 5 points, an AT lottery is performed. At this time, the failure point is initialized to 0 points regardless of whether or not the AT is won (whether or not the navigation stock is given). Also, when the AT is won under another condition (for example, reaching the ceiling), the number of digest games is reset to 0 points. In addition, when AT is won by reaching the ceiling, the number of digest games may not be reset to 0 points.

  Unlike the number of digested games, the failure point takes over the accumulated value before the occurrence of the power interruption without changing the data even when the power interruption occurs. Also, the failure point is not displayed on the liquid crystal display 51 based on the accumulated value read from the RAM 41c, unlike the number of digest games. However, the sub-control unit 91 executes a suggestion effect that suggests the accumulation status of failure points together with the accumulation of failure points. Specifically, when the failure points are accumulated in the liquid crystal display 51, a part of the screen is displayed as cracked, which indicates that the failure points are accumulated. The more failure points are accumulated, the wider the range in which the screen is cracked 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 a power interruption due to day straddling. The reason why the suggestion effect is not executed 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 day straddling. If a short period such as one game is set as the specific period, it is inappropriate as the specific period because the player will notice that the failure points are accumulated by playing one game. 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 the 20 games are played. The suggestion effect is executed based on the failure point information of the gaming state command received from the main control unit 41 by the sub control unit 91. In the present embodiment, the suggestion effect that suggests the accumulation status of the execution failure points is not executed in the specific period after returning from the power interruption due to the day straddling. However, the present invention is not limited to this, and the suggestion effect may not be performed at all. That is, as described above, the failure points are accumulated with the progress of the game in the non-AT state and stored in a predetermined area of the RAM 41c, but no suggestion effect due to the accumulation of the failure points is performed. However, in the AT lottery when the failure point reaches 5 points, when the AT is won, the liquid crystal display 51 notifies that fact.

[Setting change processing]
The setting change process executed by the main control unit 41 will be described with reference to FIG. FIG. 6 is a flowchart showing the control content of the setting change process executed by the main control unit 41. The setting change process is a process executed in the startup process (main). In the setting change process, the setting value is changed based on an operation by a setting switch (or a reset switch), and an initialization process, a random value acquisition process, 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 a 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 points and the bonus information. The failure point is data that is not subject to initialization in the initial process due to the setting change. That is, even when the setting change process is executed, the data is maintained before and after that. The payout work is an area in which numerical values (including failure points) related to an advantageous state such as AT excluding bonuses and numerical information related to payout are stored. For example, the number of digest games in the non-AT state, data that can specify that the game is in AT and CZ are stored. In the initialization process by setting change, this area is initialized, but only the failure point is not initialized exceptionally. The bonus information is an area in which information related to the bonus is stored. For example, data capable of specifying that a bonus is being stored is stored.

  Next, the main control unit 41 acquires a random value from a range of 1 to 256 generated by the random number clock of the random number clock generation circuit 43 (Sf4). Next, the acquired random number value is set as an accumulated value (number of digested games) stored in the RAM 41c (Sf5). At this time, the main control unit 41 first deletes the accumulated value (the number of digested games) stored in the RAM 41c and substitutes the initial value (0). Next, the main control unit 41 substitutes the random value as it is instead of the initial value (0) stored in the RAM 41c. Thus, the acquisition of the random value is performed after the set value change process is started.

  The main control unit 41 reads the current set value from the RAM 41c, converts the read set value into a display value (Sf6), and displays the converted display value on the set value display 24 (Sf7). Thereafter, the main control unit 41 determines whether or not 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 a 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 ( Sf7).

  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 or not 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 a predetermined period (YES in Sf10), the main control unit 41 converts the display value displayed on the set value display 24 into a set value and stores it in the RAM 41c. (Sf11).

  Next, the main control unit 41 determines whether or not the setting key switch 37 is in the off state (Sf12). When it is not determined 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 main control unit 41 returns to the processing of Sf12. On the other hand, when the main control unit 41 determines that the setting key switch 37 is in the off state (YES in Sf12), the main control unit 41 proceeds to the processing of Sg13.

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

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

  FIG. 7A shows a specific example of the digest game number change process when the setting change process is executed. It is assumed that the number of digest games stored in the RAM 41c immediately before the setting change process is “550”. By executing the setting change process, the number of digest games is initialized and the value becomes “0” (Sf3 in FIG. 6). Next, a random value is acquired from the range of 1 to 256 generated by the random number clock of the random number clock generation circuit 43 (Sf4 in FIG. 6). Here, it is assumed that “115” is acquired as the random value. Next, the obtained random number value “115” is directly set as the number of digest games (Sf5 in FIG. 6). As a result, the number of digested games stored in the RAM 41c is set to “115”.

  In the present embodiment, the range of random values that can be acquired is 1 to 256. If a numerical value higher than that is to be substituted for the accumulated value in the storage area of the RAM 41c, the acquired random number value may be modified. For example, the acquired random number value may be multiplied by 4 and then set as the number of digest games. In the present embodiment, the ceiling of the number of digest games is 1000 games with respect to the range of random numbers 1 to 256. Therefore, if the random number value is directly substituted for the accumulated value in the storage area of the RAM 41c, the range of 257 to 1000 is obtained. The number of digest games cannot be set. For this reason, the number of digested games before power interruption and the number of digested games set by random numbers will be different. By multiplying the random value by four, a numerical value in the range of 4 to 1024 (256 × 4) can be set, so that a numerical value closer to the number of digested games before power interruption can be set.

  FIG. 7B shows a specific example when the acquired random number value is quadrupled. It is assumed that the number of digest games stored in the RAM 41c immediately before the setting change process is “550”. By executing the setting change process, the number of digest games is initialized and the value becomes “0” (Sf3 in FIG. 6). Next, random numbers in the range of 1 to 256 are acquired (Sf4 in FIG. 6). Here, it is assumed that “115” is acquired as the random value. Next, the obtained random number value is multiplied by four (“115” is changed to “460” (= 115 × 4)). Finally, a numerical value “460” obtained by multiplying the acquired random number value by four is set as the number of digest games (Sf5 in FIG. 6). As a result, the number of digest games is set to “460”.

  By multiplying the random number by four, a numerical value in the range of 4 to 1024 (256 × 4) can be obtained. However, when the value exceeds 1000 which is the ceiling, it may be set as 1000. However, at this time, if a numerical value in the range of 1000 to 1024 is obtained, it always reaches the ceiling. At this time, the player can start a game with a slot machine that suddenly reaches the ceiling (that is, in an AT winning state) when a power outage occurs due to straddling the day (that is, in the morning in the opening hours of the hall). End up. The player can check whether or not the AT is won by playing a plurality of slot machines one game at a time in the morning. In this way, if the number of players who do not play games on a table that has not won an AT increases, the operating rate of the hall will drop.

  In order to avoid such a situation, when the ceiling of 1000 is exceeded, a numerical value smaller than the ceiling may be set. For example, the upper limit is 980. As a result, even if the upper limit value 980 is set, the player cannot determine whether or not the ceiling has been reached unless he / she has played 20 games.

  The random value acquisition process (Sf4 in FIG. 6) executed in the setting change process executed by the main control unit 41 is also executed as a common process in other processing means. For example, 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]
With reference to FIG. 8, the navigation stock provision conditions (AT winning conditions) will be described. FIG. 8 is a diagram for explaining navigation stock provision conditions. As shown in FIG. 8, in the non-CZ, the navigation stock can be given when the number of digested games reaches the ceiling (1000 games) and when the failure points reach 5 points.

  If the number of digested games reaches 1000 in non-CZ, AT is won with a probability of 100% (navigation stock is given). The number of navigation stocks given is determined by the AT lottery shown in FIG. The probability of being given 1 Navistock is 40%, the probability of being given 2 Navistock is 30%, the probability of being given 3 Navistock is 20%, and the number of Navistock is 4 The probability of being granted is 10%. The number of digested games is initialized to 0 game when 1000 games on the ceiling are reached.

  The number of navigation stocks is not determined by lottery, but a predetermined number of navigation stocks (for example, 1) may be given. Further, the navigation stock may not be provided with a probability of 100%, for example, the navigation stock may not be provided with a predetermined probability (for example, 10%). In this case, the number of digest games is initialized to 0 games when 1000 games are reached, regardless of whether or not Navi stock is given (AT win). In addition, for each predetermined number of games until the ceiling (1000G) is reached (for example, every 100G), it may be determined whether or not to provide navigation stock. For example, navigation stock is given with a probability of 50%. When the Navistock is won, the number of digested games may be initialized (0 game), and when not won, the number of digested games may be continued without being initialized.

  In addition, when the failure point reaches 5 points in the non-CZ, an AT lottery (a lottery for determining whether or not to provide navigation stock) is performed. The probability of not winning an AT is 20%. The probability of winning an AT and being given Navistock is 80%. When the navigation stock is provided, the number of navigation stocks to be provided is determined by lottery. The probability of being given 1 Navistock is 35%, the probability of being given 2 Navistock is 25%, the probability of being given 3 Navistock is 15%, and the number of Navistock is 4 The probability of being granted is 5%. The failure point is initialized to 0 game when 5 points are reached.

  Although not shown in the drawing, in CZ, the case where a specific lottery winning combination is won is the navigation stock granting condition. Specifically, it corresponds to a specific lottery target for watermelon and cherry. If you win a watermelon or cherry, a lottery will be held to determine whether or not to grant Navistock. When winning Navistock, 1 to 4 Navistock numbers will be given by lottery. Navi stock provision conditions in CZ are higher than non-CZ navigation stock provision conditions, and navigation stock is easily provided in CZ.

[Number of digested games when settings are changed, etc.]
With reference to FIG. 9, a time chart showing the transition of the number of digested game displays when the setting is changed will be described. FIG. 9 is a time chart showing the transition of the number of digest games displayed when the setting is changed. In FIG. 9, the number of digested games displayed on the liquid crystal display 51, the number of digested games stored in the RAM 41c, and the transition of failure points stored in the RAM 41c will be described. The power interruptions that occur at times t2 and t4 are the power interruption caused by a power failure (instant interruption etc.) during the business hours of the amusement store, and the employees etc. power the slot machine 1 during the non-business hours of the amusement store. The power interruption that occurs by cutting is assumed.

  In FIG. 9, the horizontal axis indicates time t. Here, “on” in the “setting change process” indicates that the setting has been changed by the setting change process. “On” in “AT winning” indicates that the AT lottery has been executed and the AT has been won. “On” of “Power” indicates a state in which power is supplied to the slot machine 1, and “off” indicates a state in which power is not supplied to the slot machine 1.

  Here, the time from t4 is the business hours of the amusement store, and the time from t4 to t5 is the non-business hours after the store is closed. After the time t5, it is the next business day. For example, when the business hours are from 10:00 am to 11:00 pm, time t4 is 11:00 pm, which is the business end time of the day, and time t5 is 10:00 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.

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

  It is assumed that at time t2, the 586 game is digested while remaining in the non-AT state. At this time, the number of digested games stored in the RAM 41c is “586”. Further, the number of digested games displayed on the liquid crystal display 51 is also “586G”. In addition, it is assumed that in the period from time t1 to t2, two non-CZ winning results are obtained in the CZ lottery. At this time, the failure point is updated from 0 to 2 and stored in the RAM 41c. Furthermore, a suggestion effect is displayed in which a part of the screen of the liquid crystal display 51 is cracked due to the accumulation of failure points. When the failure point is 1, a part of the screen is displayed as cracked. When the failure point is changed from 1 to 2, the range in which the screen appears to be cracked becomes wider.

  It is assumed that a momentary interruption due to a power failure occurs during business hours at time t2. The power supply of the slot machine is turned off due to a power failure, and a power failure occurs. Then, the power of the slot machine is turned on by returning from the power failure at time t3.

  At time t3, the number of digested games (liquid crystal display 51), the number of digested games (RAM 41c), and the failure points (RAM 41c) all maintain the values before the occurrence of power interruption.

  It is assumed that at time t3 to t4, the game is further digested up to 726 games in the non-AT state. At this time, the number of digested games stored in the RAM 41c is “726”. In addition, the number of digested games displayed on the liquid crystal display 51 is also “726G”. Further, it is assumed that one non-CZ winning result is obtained in the CZ lottery during the period from time t3 to t4. At this time, the failure point is updated from 2 to 3, and stored in the RAM 41c. By accumulating the failure points, a suggestion effect is made that further expands the range in which the screen looks like a crack.

  Time t4 shows a situation in which a power interruption occurs when an employee or the like turns off the power of the slot machine 1 during the non-business hours. At the time t4, the business is ended and the power is turned off, and the power of the slot machine 1 is turned on at the time t5 after the time Ts (that is, the power interruption is recovered from the time Ts (for example, 4:00 am) and has returned to the state straddling the day that occurred across).

  At time t4 when power interruption occurs (at the end of business hours), the number of digested games displayed on the liquid crystal display 51 is “726G”, but time t6 after returning from power interruption (when business hours start on the next day) ) Is displayed as “0G”.

  The number of digested games stored in the RAM 41c is initialized by setting change and becomes zero. Furthermore, a random value is acquired from a numerical value in the range of 1 to 256 in the subsequent processing. Here, 115 is acquired. As a result, the number of digest games in the RAM 41c is rewritten to 115.

  Since the failure point is data that is not initialized by a setting change, the failure point is still maintained as “3”. When returning from a power interruption by straddling a day, a suggestion effect that suggests accumulation of failure points is not executed for a specific period (20 games).

  It is assumed that 885 games are further digested in the non-AT state at times t6 to t7, and the number of digest games stored in the RAM 41c has reached “1000”. However, since the display of the number of digest games displayed on the liquid crystal display 51 starts from “0G”, “885G” is displayed when the 885 games are digested. Further, it is assumed that one non-CZ winning result is obtained in the CZ lottery in the period from time t6 to t7. At this time, the failure point is updated from 3 to 4 and stored in the RAM 41c. By accumulating the failure points, a suggestion effect is made that further expands the range in which the screen looks like a crack.

  At time t7, the number of digested games stored in the RAM 41c reaches “1000”, ie, “ceiling”, so that an AT win is won. At this time, as shown in FIG. 8, the navigation stock in the range of 1 to 4 is given by lottery. By winning the AT, the digest game number display (liquid crystal display 51), digest game number (RAM 41c), and failure point (RAM 41c) are all reset to zero. When the failure point becomes 0, the suggestive effect suggesting the accumulation of the failure point is not performed.

  Here, the time Ts is set in a non-business hours (for example, 4 am) in the present embodiment. The time Ts is set to a time zone in which the power of the slot machine 1 in the non-business time zone is turned off. In this way, when there is a momentary break in the business hours, at the start of business hours (time t4), the display of the number of digested games can be returned to “0G” uniformly. .

[Number of digested games displayed when settings have not been changed]
With reference to FIG. 10, a time chart showing the transition of the number of digested game displays and the like when there is no setting change will be described. FIG. 10 is a time chart showing the transition of the digest game number display and the like when there is no setting change. Hereinafter, description of the same parts as those in FIG. 9 is omitted.

  In FIG. 10, the horizontal axis indicates time t. In FIG. 10, unlike 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 time t5 is the same as the description of FIG.

  At time t4 when power interruption occurs (at the end of business hours), the number of digested games displayed on the liquid crystal display 51 is “726G”, but at time t5 (when business hours start on the next day) after returning from power interruption. Is displayed as “0G” as in FIG. 9. Further, since the setting change process is not performed, the number of digest games stored in the RAM 41c is still maintained as “726”. Also, the failure point is maintained as “3”. When returning from a power interruption by straddling a day, a suggestion effect that suggests accumulation of failure points is not executed for a specific period (20 games).

  It is assumed that at time t5 to t6, 274 games are further digested in the non-AT state, and the number of digest 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. Further, it is assumed that one non-CZ winning result is obtained in the AT lottery during the period from time t5 to t6. At this time, the failure point is updated from 3 to 4 and stored in the RAM 41c. By accumulating the failure points, a suggestion effect is made that further expands the range in which the screen looks like a crack.

  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 navigation stock in the range of 1 to 4 is given by lottery. By winning the AT, the digest game number display (liquid crystal display 51), digest game number (RAM 41c), and failure point (RAM 41c) are all reset to zero. When the failure point becomes 0, the suggestive effect suggesting the accumulation of the failure point is not performed.

[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 returns from the power interruption, as shown at time t6 in FIG. 9, when the set value is changed, the number of digest games stored in the RAM 41c corresponds to the random value. Instead of the value 115. For this reason, when the set 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. Further, as shown at time t3 in FIG. 9 and time t3 and time t5 in FIG. 10, when the slot machine 1 returns from the power interruption, the number of digest games is maintained when the set value is not changed. As shown at time t6 in FIG. 9, when the set value is changed, the number of digest games stored in the RAM 41c is replaced with a value 115 corresponding to the random value. For this reason, the difference between the number of digested games is reduced when the set value is changed and when the set value is not changed, compared to the case where the number of digested games is changed to the initial value 0 when the set value is changed. be able to. Therefore, even if the set value is changed, there is a low possibility that it is recognized that the set value has been changed based on the number of digest games.

  Further, as shown in FIG. 8, since the number of digest games reaches 1000 games (ceiling), the AT is won and the number of navigation stocks of 1 to 4 is given by lottery, so the interest is improved.

  In addition, when determining whether or not to win an 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. Regardless, since the number of digested games is 0, it becomes easy for the player to accumulate the number of digested games aiming at 1000 games again.

  Further, when returning from the power interruption, as shown at time t5 in FIG. 10, the digest game number display is 0 game, and the digest game number is updated from 726 before the power interruption, while the digest game number display is Updated from 0. For this reason, when multiple slot machines return from power interruption all at once, all slot machines display the initial game 0, so that there is no difference in the display for each slot machine. it can.

  Also, as shown at time t6 in FIG. 9, the failure point is maintained at 3 even when the setting change process is executed. In addition, a suggestion display based on the accumulation of failure points is performed on the liquid crystal display 51. Specifically, when failure points are accumulated, a part of the screen is displayed as cracked. The more failure points you accumulate, the wider the screen will appear to crack. As shown after time t5 in FIG. 9 and after time t5 in FIG. 10, since the suggestion effect suggesting the accumulation of failure points is not performed during the specific period (20 games), It is possible to prevent the difference in the situation from being determined.

  In addition, as shown at time t6 in FIG. 9, when the setting is changed when the slot machine 1 returns from the power interruption, the accumulated number of digested games is substituted with the random number value 115. The maximum value of the numerical value is smaller than 1000 which is the ceiling. For this reason, it is possible to prevent a situation advantageous to the player from occurring due to the number of digested games suddenly reaching the ceiling (1000 games).

  Further, in the AT lottery process, the CZ lottery process, and the freeze lottery process, since the random value is acquired by the process common to Sf4 shown in FIG. 6, the processing load of the random value acquisition after the power failure recovery can be reduced. .

  In addition, since a random number value is acquired by the processing of Sf4 as shown in FIG. 6 after a predetermined period from the control to the setting change state, it is possible to generate a random value at a timing related to the setting change state. it can.

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

[About setting change processing]
A modified example of the setting change process executed by the main control unit 41 will be described with reference to FIG. FIG. 11 is a flowchart illustrating 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 a 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 failure points and bonus information.

  The main control unit 41 reads the current set value from the RAM 41c, converts the read set value into a display value (Sg4), and displays the converted display value on the set value display 24 (Sg5). Thereafter, the main control unit 41 determines whether or not the setting switch has been operated by the store clerk (Sg6). When it is determined that the setting switch has been operated within a 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 ( Sg5).

  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 or not 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 Sg8), the main control unit 41 returns to the processing of Sg6.

  On the other hand, when the main control unit 41 determines that the start switch 7 has been operated within a predetermined period (YES in Sg8), the main control unit 41 converts the display value displayed on the set value display 24 into a set value and stores it in the RAM 41c. (Sg9).

  Next, the main control unit 41 determines whether or not the setting key switch 37 is in the off state (Sg10). When it is not determined 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 main control unit 41 returns to the processing of Sg10. On the other hand, when the main control unit 41 determines that the setting key switch 37 is in the off state (YES in Sg10), the main control unit 41 proceeds to the processing of Sg11.

  The main control unit 41 acquires a random number value 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 value as the number of digested games (Sg12).

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

  In this way, 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 value is acquired by the processing of Sg11. The random number generation process can be performed at a timing related to the setting change state.

[Granting Navistock]
In the present embodiment, as shown in FIG. 8, when the number of digested games has reached 1000 games and when the number of failure points has reached 5 points, a lottery regarding the provision of navigation stock is performed. However, the present invention is not limited to this, and even when a specific lottery target combination is won, a lottery regarding the provision of navigation stock may be performed. For example, when a specific lottery target such as watermelon or cherry is won, a lottery is performed to determine whether or not to provide navigation stock. When winning the navigation stock, as shown in FIG. 8, the number of navigation stocks 1 to 4 is given by lottery. The grant probability of navigation stock and the expected value of the number of navigation stock to be granted may be changed according to the lottery role. For example, when the cherry is won, the navigation stock winning probability may be set higher than when the watermelon is won, and the expected value of the number of navigation stocks to be given may be set higher. At this time, the failure point may not be awarded when the CZ lottery is not won, but may be given when the AT lottery is not won. The number of ceiling games is not limited to 1000 games, and may be an arbitrary number of games. For example, it may be 100 games, 77 games that are the number of eyes, 111 games, and the like.

[About judgment of day stride]
In the present embodiment, as shown in FIG. 5, when a power interruption occurs, the initialization flag 2 is turned on when the power recovery time is after AM 4:00, and it is confirmed that the day stride has occurred. Judgment. However, the present invention is not limited to this, and the initialization flag 2 may be turned on when a predetermined period of time (for example, 6 hours) has elapsed since the power interruption, and it may be determined that the day stride has occurred.

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

  In the present embodiment, the number of digested games is accumulated in a non-AT state (a state not controlled by the AT, including a non-CZ state and a CZ state). However, the present invention is not limited to this, and the number of digest games may be accumulated in the normal section. That is, accumulation may be performed in a state other than the AT state and the CZ state.

[Modification of slot machine]
In the above embodiment, the slot machine that pays out game media to the player's hand according to the occurrence of a win has been described. However, the game medium is enclosed, and the game media is paid out to the player's hand when a win occurs. An enclosing slot machine that adds game points (scores) without any change may be adopted. The base and the drum can be distributed, and the chassis is common and only the base or the base and the drum is called a gaming machine. In addition, the slot machine has a game area in which a game ball can be launched and a game can be played, and a betting amount can be set according to the game ball passing through a predetermined area provided in the game area. May be.

[About benefits]
In the above-mentioned example, the value directly affecting the payout rate of medals and pachinko balls, such as bonus winning, AT winning, number of navigation stocks, CZ winning, etc. is exemplified as the privilege. However, the privilege may be a value that improves the degree of advantage for the player, and may be a value that does not directly affect the medal payout rate, for example.

  Specifically, when an AT lottery has a high probability state in which AT is won with a higher probability than usual, execution of a probability suggestion effect to suggest whether or not the current state is a high probability state , Execution of a premier effect together with sound on the liquid crystal display 51 (special character appearance, execution of special bonus effect in the next generated bonus, etc.), execution of a set value suggestion effect to suggest a set value, Collecting a certain number of liquid crystal displays a two-dimensional code that gives points that can be exchanged for services determined at the amusement store where the slot machine 1 is installed, and that can download bonus videos and bonus information on a predetermined website A display or the like may be displayed in the device 51.

  Moreover, although the number of navigation stocks is illustrated as an example of the benefits, the benefits related to the AT are not limited to this, but the number of times that the navigation effects can be performed is determined and the number of times that the navigation effects can be performed is determined. When performing the AT control until the navigation effect is executed, the number of times that the navigation effect can be executed may be used as a privilege.

  Further, for example, when the upper limit grant amount is determined and the AT is controlled until the assigned game value (medal payout number) reaches the determined upper limit grant amount, the upper limit grant amount may be a privilege. In addition, when the AT is controlled from when the predetermined AT start condition is satisfied until the predetermined AT end condition is satisfied, and if the AT is continued when the AT end condition is satisfied, the continuous lottery is performed. The continuation probability determined to continue in the lottery may be used as a privilege.

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

  Advantageous states include, for example, a regular bonus (RB) and replay time (RT) in which a winning probability of a predetermined winning combination is high, a concentrated state of small roles, and a range in which at least one reel can be pulled in than normal. The operation procedure for winning the winning small role is not predetermined, but the challenge time (CT) and the winning probability of winning the winning role are not changed. It may be a pseudo bonus that is 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, the probability of being controlled to the freeze state is high, the number of games such as the number of navigation stock is high probability You may set the advantageous state of a different aspect from the said embodiment, such as the state added and the state where it is easy to increase the number of additional games of AT. In addition, it is indirectly advantageous for the player, such as the condition for obtaining a privilege on the communication line network and the probability of establishing a condition for executing a premium effect (freeze effect, premium effect, etc.). It may be a state where a special privilege or an interest of the game is improved. Further, the allowance determining means for determining whether or not to allow the transition to an advantageous state is not limited to the internal lottery process, and may be a means for determining regardless of the winning combination.

  Further, the advantageous state is given when, for example, in the privilege grant lottery that determines whether or not a privilege is granted, the “probability that a privilege is granted” and “the privilege is given” are determined. At least one of “the value of the privilege (or the expected value of the privilege)” may be higher than the normal state (a state different from the advantageous state). In addition, the advantageous state may be one in which the number of execution opportunities for the privilege grant lottery is greater than in the normal state. In addition, the advantageous state may be a state where the number of digestion-required games that need to be digested in order to give a privilege is less than a normal state.

  For example, when the privilege is the number of navigation stocks, the advantageous state is that “the AT winning probability in the AT lottery” and “navigation given when the AT is won in the AT lottery” than the normal state. At least one of “the value of the number of stocks” may be higher than the normal state. Further, the advantageous state may be that the number of AT lottery triggers is larger than that in the normal state. For example, when the AT lottery execution opportunity in the normal state is the first role winning and the second role winning, the AT lottery execution opportunity in the advantageous state is the first role winning and the second role winning. In addition to the above, it is possible to win the third role.

[About production and notification]
In the above-described example, an example in which the liquid crystal display 51 is used to produce effects and notifications is given. For example, speakers 53 and 54, a back lamp (reel LED 55 in the above embodiment) arranged on the back side (inside) of the reel. ), Transmissive liquid crystal display arranged on the front side of the reel (liquid crystal display configured so that the reel can be seen), lamps and LEDs mounted on the front door 1b, etc., vibration of the stop switch, around the stop switch The effect may be executed by means different from the above-described embodiment, such as air blowing from the air or a change in the temperature of the stop switch.

[About AT]
In the example of the slot machine, the example in which the main control unit 41 executes the control related to the AT has been described. However, the AT related control executed by the main control unit 41 includes execution of an AT lottery. The AT lottery may include winning or non-winning AT lottery, determining whether or not to store the number of navigation stocks, determining the number of navigation stocks, adding the number of navigation stocks, and the like. In addition, as a control related to the AT, a high probability state control of the AT lottery is exemplified. For the control of the high probability state of AT lottery, the control that increases the probability of winning the AT lottery, the control that shortens the period until the AT is controlled according to the result of the internal lottery, the winning probability of the extra lottery and the game Includes controls that favor numbers.

  Further, as control related to AT, control for setting a precursor period can be cited. The control for setting the precursor period includes, for example, control for producing effects of 0 to 32 games in the precursor period before the start of AT.

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

  In addition, as the control related to AT, the main control unit 41 performs lighting control of lamps and LEDs for executing a navigation effect. Further, the sub control unit 91 may execute the navigation effect in conjunction with the main control unit 41 executing the navigation effect. Further, when the main control unit 41 improves the lottery probability, for example, when controlling to the high probability state of the AT lottery, for example, this is notified by lighting control of a lamp or LED (for example, the game auxiliary display 12). You may do it.

  More specifically, the main control unit 41 may notify that it is controlled to the high probability state of the AT lottery by executing the navigation effect a predetermined number of times by the game auxiliary display 12. Alternatively, the main control unit 41 may notify the sub-control unit 91 that the navigation effect is executed a predetermined number of times to control to the high probability state of the AT lottery.

  When the main control unit 41 executes the control related to the AT, it is preferable that the process of the main control unit 41 is executed by the control unit subordinate to the main control unit 41 and subordinate to the main control unit 41. . For example, the control unit provided on the board other than the game control board executes the reel stop control, and the main control unit 41 transfers the operation signal of the stop switch to the control unit. In this way, by causing the lower-level control unit to perform the control of the main control unit 41, it is possible to prevent the capacity of the ROM 41b and the RAM 41c from being insufficient and the processing capacity of the main CPU 41a from being insufficient when performing control related to the AT.

  In the above-described embodiment, the main control unit 41 executes the control related to the AT. However, the sub-control unit 91 may execute the control. The sub-control unit 91 performs, for example, an AT lottery process or an extra lottery process based on an internal winning command from the main control unit 41, and executes a process for controlling the AT or a navigation effect according to the result. Processing or the like may be performed.

[Setting change status and setting check status]
With regard to the setting change state, it is possible to shift to the setting change state on condition that “power supply on” + “setting key switch on” + “front door opening detection”. Thereby, an unauthorized setting change in a state where the front door is not opened can be prevented. Once the setting change state is entered, the setting change state is maintained regardless of the open / closed state of the front door until the end condition (setting key switch is turned off after setting value is established) is satisfied. You may make it do. As a result, even if the front door is closed during the setting change state, the setting change state is not terminated, so that it is possible to prevent the trouble of shifting to the setting change state again.

  Further, regarding the setting confirmation state, the setting confirmation state may be shifted to “setting key switch on” + “front door opening detection”. Thereby, unauthorized setting confirmation in the state where the front door is not opened can be prevented. Once the setting confirmation state is entered, the setting confirmation state is maintained regardless of whether the front door is open or closed until an end condition (setting key switch is turned off) for ending the setting confirmation state is satisfied. Also good. Thereby, even if the front door is closed during the setting confirmation state, the setting confirmation state is not terminated, and therefore it is possible to prevent the trouble of shifting to the setting confirmation state again.

  In the above-described embodiment, a plurality of reels capable of variably displaying each of a plurality of types of identifiable symbols are provided, and after the reels are variably displayed, the display result is derived by stopping the variability display of the reels. A slot machine that can generate a winning according to the combination of reel display results has been described. In other words, a plurality of variable display units capable of variably displaying a plurality of types of identification information each identifiable are provided, and after the variable display unit is variably displayed, the display result is derived by stopping the variable display of the variable display unit. The slot machine is described in which a winning can be generated according to a combination of display results of a plurality of variable display units. However, a variable display unit capable of variably displaying a plurality of types of identification information each identifiable is provided. After the variable display unit is variably displayed, the display result is derived by stopping the variable display of the variable display unit. As long as the slot machine can generate a prize according to the display result, the slot machine is not limited to one having three reels, but one having only one reel or a slot machine having a plurality of reels other than three. Also good.
