The following describes a first embodiment of a slot machine, which is a type of gaming machine. In this specification, the terms up, down, left, right, front, and rear refer to the directions as seen by a player playing on the slot machine.

As shown in FIG. 1, a slot machine 10 serving as a gaming machine includes a main cabinet 11 shaped like a square box. The main cabinet 11 includes an opening (not shown) on the front side. The slot machine 10 includes a front door 12 covering the opening of the main cabinet 11. The front door 12 serving as a door member is supported on the main cabinet 11 so that it can be opened and closed. The slot machine 10 includes a door open sensor KS capable of detecting that the front door 12 is open (shown in FIG. 6). The door open sensor KS corresponds to an open detection means capable of detecting that the door member is open. The slot machine 10 includes a power plug PG. The power plug PG can be connected to an external power source. The external power source is also called the main power source.

The slot machine 10 is equipped with a locking unit SJ. In the slot machine 10, the opening of the front door 12 is restricted by the locking unit SJ, and for example, the locking unit SJ can be unlocked and the front door 12 opened by operating it clockwise using a key managed by the manager of the amusement facility. The locking unit SJ can be operated clockwise and also counterclockwise. The slot machine 10 is equipped with a locking operation sensor SS that can detect when the locking unit SJ has been operated counterclockwise (shown in FIG. 6).

The slot machine 10 is provided with a decorative lamp 13 as a light-emitting means capable of emitting light on the front door 12. The slot machine 10 is provided with a speaker 14 as a sound output means capable of outputting sounds such as sound effects and music on the front door 12. The slot machine 10 is provided with a performance display device 15 on the front door 12 as a display means capable of displaying images imitating characters, letters, etc., for example. As the performance display device 15, for example, a liquid crystal display and an organic EL display can be adopted. The slot machine 10 is provided with a substantially rectangular display window 12a on the front side of the front door 12 and below the performance display device 15. The display window 12a is made of, for example, a colorless and transparent resin material. In this embodiment, some or all of the performance devices among the decorative lamp 13, the speaker 14, and the performance display device 15 correspond to the performance execution means. In this way, the performance execution means may include a light-emitting means. Also, the performance execution means may include a sound output means. Also, the performance execution means may include a display means.

The slot machine 10 includes a reel unit 16. The reel unit 16 is arranged inside the machine so that the player can see it through the display window 12a. The reel unit 16 includes a left reel 16a (first reel), a center reel 16b (second reel), and a right reel 16c (third reel). The reels 16a to 16c are also called drums. Thus, the slot machine 10 includes a plurality of reels. The reels 16a to 16c each include a pattern row along their outer periphery, in which a plurality of patterns are arranged in a distinguishable manner. The pattern row is provided by wrapping a strip-shaped translucent film on which a plurality of patterns are printed along the longitudinal direction around the outside of the reels 16a to 16c. Each of the pattern rows of the reels 16a to 16c includes 21 patterns. There are a plurality of types of patterns. For example, the multiple types of symbols include a cherry symbol that imitates a cherry, a watermelon symbol that imitates a watermelon, a bell symbol that imitates a bell, a red seven symbol that imitates a red "7", a white seven symbol that imitates a white "7", and a replay symbol that imitates the word "REPLAY". In this way, each of the reels 16a to 16c has multiple symbols.

The reel unit 16 includes an actuator for driving the left reel 16a, an actuator for driving the center reel 16b, and an actuator for driving the right reel 16c. For example, a stepping motor can be used as the actuator for driving the reels 16a to 16c. The reels 16a to 16c can be rotated and stopped vertically independently of each other by the actuators provided corresponding to each of them. In the slot machine 10, when the reels 16a to 16c rotate, the pattern row (multiple types of patterns) visible through the display window 12a is changed, and a variation game is executed. For example, the variation of the pattern row is performed in a manner in which the pattern row is scrolled vertically from top to bottom. In this way, the slot machine 10 is configured to be able to execute a variation game in which the multiple reels 16a to 16c rotate. The reel unit 16 also includes a left reel sensor SE1 for detecting the rotational position of the left reel 16a, a center reel sensor SE2 for detecting the rotational position of the center reel 16b, and a right reel sensor SE3 for detecting the rotational position of the right reel 16c (shown in FIG. 6).

The display window 12a as a display unit is large enough to display three consecutive symbols in the circumferential direction on the reels 16a to 16c. An upper stop position, a middle stop position, and a lower stop position are set in the display window 12a for each of the reels 16a to 16c. When the reels stop rotating, one symbol is displayed at each of the upper stop position, the middle stop position, and the lower stop position. Then, the symbol stopped at each stop position can be seen through the display window 12a, and the symbol is displayed in the display window 12a. In other words, when some or all of the reels 16a to 16c stop rotating, it is possible to see through the display window 12a a total of three symbols that are stopped at at least the upper stop position, the middle stop position, and the lower stop position among the multiple symbols of the reel that has stopped rotating. In other words, in this embodiment, when a reel stops, at least some of the multiple symbols of the reel are displayed in the display unit.

In the slot machine 10, a combination of valid stop positions that can determine that the stopped symbol combination is a winning combination is set by a combination of stop positions selected one by one from the three stop positions set for each reel 16a to 16c. In the following explanation, a line connecting multiple stop positions that make up a valid combination of stop positions is simply referred to as an "active line YL." In this embodiment, the active line YL (a combination of valid stop positions) is made up of each of the middle stop positions of the reels 16a to 16c. The active line YL is also called a winning line.

Here, "stopped" with respect to the symbols means that the symbols are stopped in the display window 12a, i.e., at one of the upper, middle, or lower stop positions, and are displayed so as to be visible to the player. Also, "winning" means that a symbol combination for which a prize is determined is displayed on the winning line YL. In the slot machine 10, when a prize is won, the prize determined for the winning symbol combination is awarded. Note that combinations other than the valid stop position combinations are invalid stop position combinations (so-called invalid lines) in which the displayed symbol combination cannot be determined as a winning combination. Hereinafter, "game result derived in the variable game" corresponds to a symbol combination that is stopped on the winning line YL in the variable game.

The slot machine 10 has a medal insertion slot 17 on the front side of the front door 12, into which medals are inserted as gaming media. The slot machine 10 has a bet button 18 on the front side of the front door 12. The bet button 18 is a means for betting medals (hereinafter referred to as betting) from credits stored internally in the slot machine 10. The slot machine 10 has a settlement button 19 on the front side of the front door 12. The settlement button 19 is a means for paying back bet medals and credits stored internally in the slot machine 10.

The slot machine 10 is equipped with a start lever 20 as a start operation unit on the front of the front door 12. The start lever 20 is a means for performing a start operation to start the rotation of the reels 16a to 16c. In other words, the acceptance of the start operation triggers the start of the variable game. The operation of the start lever 20 to start the variable game can be said to be a start operation. In the slot machine 10, the variable game is started based on the start operation.

The slot machine 10 is provided with a left stop button 21 (first stop button) on the front of the front door 12. The left stop button 21 corresponds to the left reel 16a and is a means for performing a stop operation to stop the rotation of the left reel 16a. The slot machine 10 is provided with a center stop button 22 (second stop button) on the front of the front door 12. The center stop button 22 corresponds to the center reel 16b and is a means for performing a stop operation to stop the rotation of the center reel 16b. The slot machine 10 is provided with a right stop button 23 (third stop button) on the front of the front door 12. The right stop button 23 corresponds to the right reel 16c and is a means for performing a stop operation to stop the rotation of the right reel 16c. The stop buttons 21 to 23 correspond to the multiple pattern rows respectively. The stop buttons 21 to 23 each correspond to a stop operation unit. In this way, the slot machine 10 is configured to be able to stop the rotation of the reels when the stop button is operated. Furthermore, the operation of the stop button to stop the reels while they are spinning can be considered a stop operation. In the slot machine 10, the rotation of the reels is stopped based on the stop operation. As described above, the slot machine 10 is equipped with a plurality of stop buttons 21-23 as stop operation means corresponding to the plurality of reels 16a-16c, respectively. In the following description, the first stop operation of the stop buttons 21-23 will be referred to as the first stop operation, the second stop operation will be referred to as the second stop operation, and the third stop operation will be referred to as the third stop operation.

In addition, in the slot machine 10, when the reels stop spinning in a variable game as a result of the stop button being operated, a stopping sound (e.g., a banging sound) is output from the speaker 14. In this embodiment, the stopping sound corresponds to a non-specific sound. That is, in this embodiment, the sounds that can be output by the sound output means include at least a non-specific sound.

As shown in FIG. 2, there are six different sequences of operation of the stop buttons 21 to 23 (hereafter referred to as push sequences), from the first push sequence to the sixth push sequence, in which the stop buttons for the first stop operation, the second stop operation, and the third stop operation are performed in different push sequences. The first push sequence is a sequence in which the stop buttons 21 to 23 are operated so that the left reel 16a, the center reel 16b, and the right reel 16c are stopped in this order. The second push sequence is a sequence in which the stop buttons 21 to 23 are operated so that the left reel 16a, the right reel 16c, and the center reel 16b are stopped in this order. The third push sequence is a sequence in which the stop buttons 21 to 23 are operated so that the center reel 16b, the left reel 16a, and the right reel 16c are stopped in this order. The fourth push sequence is a sequence in which the stop buttons 21 to 23 are operated so that the center reel 16b, the right reel 16c, and the left reel 16a are stopped in this order. The fifth push order is the push order of the stop buttons 21 to 23 to stop the rotation of the right reel 16c, left reel 16a, and center reel 16b in that order. The sixth push order is the push order of the stop buttons 21 to 23 to stop the rotation of the right reel 16c, center reel 16b, and left reel 16a in that order.

As shown in FIG. 1, the slot machine 10 has a medal payout outlet 26 at the bottom of the front of the front door 12. The slot machine 10 has a receiving tray 27 that receives medals paid out from the medal payout outlet 26. The slot machine 10 has a medal selector inside the machine. The medal selector has an insertion sensor SE4 that detects medals inserted through the medal insertion port 17 (shown in FIG. 6). The slot machine 10 has a hopper unit HU (shown in FIG. 6) inside the machine that is capable of performing a payout operation to pay out medals from the medal payout outlet 26.

The slot machine 10 is equipped with an up button B1 and a down button B2 on the front of the front door 12. Both the up button B1 and the down button B2 can be operated by the player. In this embodiment, the up button B1 and the down button B2 correspond to the operable adjustment operation means.

The slot machine 10 is provided with an information panel 30 on the front surface of the front door 12, which can display predetermined information.
As shown in Fig. 3, the information panel 30 has an insertion possibility display section 31. The insertion possibility display section 31 displays whether or not the slot machine 10 is in a state in which a medal can be inserted, for example, by the lighting state of an illuminator (not shown). The information panel 30 has a replay display section 32. The replay display section 32 displays whether or not a replay (replay) is being performed, for example, by the lighting state of an illuminator (not shown). Replay will be described later.

The information panel 30 includes a 1 bet display section 35a, a 2 bet display section 35b, and a 3 bet display section 35c. The 1 bet display section 35a indicates that the first medal has been bet, for example, by the lighting state of an illuminator (not shown). The 2 bet display section 35b indicates that the second medal has been bet, for example, by the lighting state of an illuminator (not shown). The 3 bet display section 35c indicates that the third medal has been bet, for example, by the lighting state of an illuminator (not shown). In the following description, the bet display sections 35a to 35c may be collectively referred to as the bet display section 35. The bet display section 35 displays the number of bets (number of bets) using the three bet display sections 35a to 35c. The "number of bets" may also be called the "number of bets."

The information panel 30 has a credit display section 36. The credit display section 36 has, for example, two seven-segment displays arranged side by side. The credit display section 36 displays the number of medals stored as credits inside the machine.

The information panel 30 also includes a payout display unit 37. The payout display unit 37 includes, for example, two 7-segment displays arranged side-by-side. The payout display unit 37 includes two 7-segment displays and is configured to display two-digit numbers in the decimal system from 00 to 99.

The payout display unit 37 also displays information about the number of medals to be paid out when a winning combination occurs in the variable game. The payout display unit 37 also displays instruction information, which is information about the operation mode of the stop buttons 21 to 23 that is recommended to derive a predetermined symbol combination (game result) in the variable game being executed. "Information about the operation mode of the stop buttons 21 to 23" includes, for example, information about the operation sequence (press order) of the stop buttons 21 to 23 and information about symbols that are recommended to be stopped by operating the stop buttons 21 to 23 in the variable game. Information about symbols that are recommended to be stopped by operating the stop buttons 21 to 23 in the variable game can also be said to be information about the eye-pressing position. In this embodiment, the payout display unit 37 corresponds to the notification means. Also, the presentation that displays instruction information on the payout display unit 37 corresponds to the presentation about the operation mode of the stop operation means executed by the notification means.

Next, the symbol combinations for which prizes are determined will be described.
A symbol combination with a fixed prize is also called a "role." Symbol combinations with fixed prizes (roles) include symbol combinations that determine the payout of medals as a prize (payout role) and symbol combinations that determine replay as a prize (replay role). Replay means that the next variable game can be started without the need to bet medals. Replay roles are also called replay roles.

The payout roles include, for example, a cherry role, a watermelon role, a bell role, and a one-piece role. The cherry role is determined to be awarded with a predetermined number of medals (e.g., three medals). In the following description, the symbol combination that stops on the effective line YL when the cherry role wins is referred to as a "cherry stop". The watermelon role is determined to be awarded with a predetermined number of medals (e.g., five medals). In the following description, the symbol combination that stops on the effective line YL when the watermelon role wins is referred to as a "watermelon stop". The bell role is determined to be awarded with a predetermined number of medals (e.g., 15 medals). In the following description, the symbol combination that stops on the effective line YL when the bell role wins is referred to as a "bell stop". The one-piece role is determined to be awarded with a predetermined number of medals (e.g., one medal). In the following description, the symbol combination that stops on the pay line YL when a single coin wins is referred to as a "bell spill stop." Note that in this embodiment, the number of medals paid out is not the number of medals actually paid out from the medal payout outlet 26, but includes the number of medals added as credits, and corresponds to the number of medals awarded to the player.

The prize for the replay role is a replay. In the following explanation, the symbol combination that stops on the active line YL when the replay role wins is referred to as a "replay stop symbol." In the following explanation, the symbol combination that stops on the active line YL when the replay role wins is referred to as a "replay stop symbol."

The slot machine 10 is configured so that the gaming state can be controlled.
As shown in Fig. 4, there are multiple types of gaming states in the slot machine 10. Specifically, the gaming states in the slot machine 10 include a first normal state, a second normal state, a first advantageous state, and a second advantageous state. In the following description, the first normal state and the second normal state may be collectively referred to as the normal state, and the first advantageous state and the second advantageous state may be collectively referred to as the advantageous state. As will be described in detail later, the advantageous state is a gaming state that is more advantageous than the normal state.

In the slot machine 10, when the first normal state is reached and a transition to the advantageous zone is determined, the state transitions to the second normal state. In the slot machine 10, when the second normal state is reached and a transition to the first advantageous state is determined, the state transitions to the first advantageous state. In the slot machine 10, when the end condition of the first advantageous state is met, if the transition condition is not met (shown as not met in FIG. 4), the advantageous zone ends and the state transitions to the first normal state. On the other hand, in the slot machine 10, when the end condition of the first advantageous state is met and the transition condition is met, the state transitions to the second normal state. In addition, in the slot machine 10, when the number of variable games executed in the first advantageous state reaches "30 times", which corresponds to the specified number of times, the end condition of the first advantageous state is met. In addition, in the slot machine 10, when the second advantageous state is transitioning to the first advantageous state, or when the second normal state is transitioning to the first advantageous state and the transition to the second advantageous state is determined by lottery, the transition condition is met, and the slot machine 10 transitions to the second advantageous state after the end of the first advantageous state. In the slot machine 10, when the number of remaining stays corresponding to the remaining number of variable games that can be played in the second advantageous state reaches 0, the advantageous zone ends and the slot machine 10 transitions to the first normal state. In addition, in the slot machine 10, when the end condition of the advantageous zone is met during the advantageous zone, the advantageous zone ends and the slot machine 10 transitions to the first normal state. In the slot machine 10, when the number of executions of the variable game in the advantageous zone reaches "1500 times" corresponding to the upper limit of stays, or when the number of game media awarded in the advantageous zone reaches "2400" corresponding to the upper limit of awards, the end condition of the advantageous zone is met.

The slot machine 10 is configured so that the presentation state (presentation mode) can be controlled.
There are a plurality of types of presentation states in the slot machine 10. Specifically, the presentation states in the slot machine 10 include a normal presentation state, a pseudo bonus presentation state, and an advantageous presentation state. The normal presentation state is a presentation state in which the player mainly stays when the player is in the normal state. The pseudo bonus presentation state is a presentation state in which the player mainly stays when the player is in the first advantageous state. The advantageous presentation state is a presentation state in which the player mainly stays when the player is in the second advantageous state. In each presentation state, presentation state identification information that can identify the presentation state during the presentation state is notified. The presentation state during the presentation state corresponds to a controlled presentation state. In the slot machine 10, for example, a background image that differs for each type of presentation state is displayed on the presentation display device 15, the decorative lamp 13 is illuminated with a different light-emitting color for each type of presentation state, and different background music is output from the speaker 14 for each type of presentation state, thereby notifying the player of the presentation state identification information. In the slot machine 10 of this embodiment, different background music (so-called BGM) is output from the speaker 14 for each type of presentation state. In this embodiment, the background music corresponds to a specific sound. That is, in this embodiment, the sounds that the sound output unit can output include at least the specific sound. By notifying the player of the presentation state identification information in this manner, the player can recognize the type of presentation state in which the player is currently playing.

In the slot machine 10, for example, an operation-related performance (hereinafter referred to as a navigation performance) is executed that suggests or notifies the operation mode of the stop button to stop a symbol combination for which a prize is determined on the pay line YL. The operation mode of the stop button suggested or notified in the navigation performance includes the order in which the stop button is pressed and the operation timing of the stop button. The operation timing of the stop button means the so-called eye-pressing position. For example, in the navigation performance, the operation timing of the stop button is suggested or notified by suggesting or notifying which symbol is to be displayed in the display window 12a and thus the operation timing of the stop button is suggested or notified. This can also be said to suggest or notify at least some of the symbols displayed in the display window 12a when the reel stops spinning. The navigation performance is also called an operation navigation performance (operation navigation) or a push order navigation performance (push order navigation). In this embodiment, the navigation performance executed in the performance display device 15 corresponds to a performance related to the operation mode of the stop operation means executed in the performance execution means.

As shown in Figure 5 (a), when a navigation performance that suggests or notifies the order in which the stop buttons should be pressed is executed, a navigation image NG is displayed in the display area above each stop button 21-23 on the performance display device 15. The navigation image NG includes a number that can be used to specify which order the stop button 21 should be operated in. A navigation image NG including a number that can be used to specify which order the stop button 21 should be operated in is displayed in the display area above the stop button 21 on the performance display device 15. A navigation image NG including a number that can be used to specify which order the stop button 22 should be operated in is displayed in the display area above the stop button 22 on the performance display device 15. Similarly, a navigation image NG including a number that can be used to specify which order the stop button 23 should be operated in is displayed in the display area above the stop button 23 on the performance display device 15. For example, the navigation effect shown in FIG. 5(a) is a navigation effect that suggests or notifies the player of the fourth press sequence, and a navigation image NG containing "3" is displayed in the display area above stop button 21, a navigation image NG containing "1" is displayed in the display area above stop button 22, and a navigation image NG containing "2" is displayed in the display area above stop button 23.

As shown in FIG. 5(b), when a navigation effect that suggests or notifies the pressing position is executed, a symbol image ZG is displayed on the effect display device 15. The symbol image ZG includes an image that imitates a symbol. The symbol included in the symbol image ZG corresponds to the symbol that is the pressing position. The symbol included in the symbol image ZG can also be said to be at least a part of the symbols that are displayed in the display window 12a when the reel rotation stops. In other words, in a navigation effect that suggests or notifies the pressing position, at least a part of the symbols that are displayed on the display unit when the reel rotation stops is suggested or notified. For example, the navigation effect shown in FIG. 5(b) is a navigation effect that suggests or notifies the white seven symbol as the pressing position, and a symbol image ZG including an image that imitates the white seven symbol is displayed on the effect display device 15.

In the slot machine 10, in the normal presentation state, the navigation presentation is not executed with contents advantageous to the player. On the other hand, in the slot machine 10, in the pseudo bonus presentation state and in the advantageous presentation state, the navigation presentation is executed with contents advantageous to the player. That is, in the pseudo bonus presentation state and in the advantageous presentation state, the rate at which the navigation presentation is executed with contents advantageous to the player is higher than in the normal presentation state. In addition, in the slot machine 10, the navigation presentation is not executed in the normal presentation state, and the navigation presentation is executed in the pseudo bonus presentation state and in the advantageous presentation state. That is, in the slot machine 10, the rate at which the navigation presentation is executed is higher than in the normal presentation state when the pseudo bonus presentation state and in the advantageous presentation state. For this reason, the pseudo bonus presentation state and the advantageous presentation state controlled in the advantageous state can be said to be more advantageous presentation states than the normal presentation state controlled in the normal state. The pseudo bonus presentation state and the advantageous presentation state can be said to be more advantageous presentation states than the normal presentation state. The pseudo bonus effect state and the advantageous effect state are what is known as "assist time (AT)". Therefore, the advantageous state is more advantageous than the normal state.

In the slot machine 10, the volume of at least some of the sounds output from the speaker 14 is adjustable. In the slot machine 10, the volume of the sounds related to the effects can be adjusted, while the volume of the sounds related to errors cannot be adjusted. In this embodiment, "adjusting the volume" can also be understood as "adjusting the output intensity of the sound." In the slot machine 10, the volume can be adjusted from among eight levels of volume. In the slot machine 10, the volume can be adjusted by operating the up button B1 or the down button B2. In this manner, in this embodiment, the volume of at least some of the sounds output from the sound output means can be adjusted by operating the adjustment operation means. In the slot machine 10, for example, the volume at which background music is output is adjustable by operating the up button B1 and the down button B2. In addition, in the slot machine 10, for example, the volume at which a stop sound is output is adjustable by operating the up button B1 and the down button B2. That is, in this embodiment, the volume at which a specific sound and a non-specific sound are output is adjustable by operating the adjustment operation means. In this manner, this embodiment is configured to be able to adjust the volume of at least some of the sounds output from the sound output means, including specific sounds and non-specific sounds, by operating the adjustment operation means. Also, for example, when a volume adjustment is performed, a volume adjustment sound that can identify that the volume adjustment has been performed may be output from the speaker 14. For example, the volume adjustment sound may be a different sound (e.g., a different scale) depending on the adjusted volume.

Next, the electrical configuration of the slot machine 10 will be described.
As shown in FIG. 6, the slot machine 10 includes a power supply board 60 inside the machine. The slot machine 10 includes a monitoring board 70 inside the machine. The slot machine 10 includes a main board 40 inside the machine. The main board 40 performs processing related to the variable game and outputs a control signal (control command) according to the result of the processing. The slot machine 10 includes a sub-board 50 inside the machine. The sub-board 50 performs processing based on a control signal input from the main board 40. The sub-board 50 controls the display performance by the performance display device 15, the performance by the decorative lamp 13, and the performance by the speaker 14. In this embodiment, the main board 40 including the main CPU 41 corresponds to the main control unit. In this embodiment, the sub-board 50 including the sub-CPU 51 corresponds to the sub-control unit that can be controlled based on control information from the main control unit. In addition, in this embodiment, the main board 40 including the main CPU 41 and the sub-board 50 including the sub-CPU 51 correspond to a processing unit that can perform processing related to the game.

First, the power supply board 60 will be described.
The power supply board 60 includes a power switch 61. The power switch 61 can be operated by opening the front door 12. That is, in this embodiment, the power switch can be operated by opening the door member. The power switch 61 is also configured to be capable of being in either an on state (ON state) or an off state (OFF state). That is, in the slot machine 10, the power switch 61 can be turned on or off by operating the power switch 61. The power switch 61 is connected to a power plug PG.

The power supply board 60 includes a power supply circuit 62. The power supply circuit 62 is connected to a power switch 61. When the power switch 61 is on, power from an external power supply is supplied to the power supply circuit 62 through the power switch 61. The power supply circuit 62 has a function of converting the voltage of the power supplied from the external power supply to a predetermined voltage. The power supply circuit 62 has a function of monitoring whether the power supplied through the power switch 61 has decreased. For example, the power supply circuit 62 may be configured to monitor whether the voltage value of the supply voltage supplied through the power switch 61 has decreased (dropped) to a predetermined value. When the power supplied through the power switch 61 decreases, the power supply circuit 62 outputs a power-off signal. The power-off signal output from the power supply circuit 62 is output to the main board 40 and the sub-board 50. Incidentally, a situation in which the power supplied through the power switch 61 decreases is, for example, a situation in which the power switch 61 is switched from an on state to an off state when the external power supply and the power plug PG are connected. Other situations in which the power supplied through the power switch 61 may be reduced include, for example, when the power switch 61 is on and the power plug PG is not connected to an external power source. Another situation in which the power supplied through the power switch 61 may be reduced includes, for example, when a power outage occurs.

When the power switch 61 is on and the external power supply and the power plug PG are connected, power is supplied to the main board 40 and the sub-board 50 through the power circuit 62. In other words, when the power plug is connected to the external power supply and the power switch is on, power is supplied to the processing unit. On the other hand, when the power switch 61 is off, power is not supplied to the main board 40 and the sub-board 50 even when the external power supply and the power plug PG are connected. However, even when the power switch 61 is off, power is supplied to the main RWM 43 and the sub-RWM 53 from the backup power supply 63 described later. Therefore, when the power switch 61 is off, the power supplied from the external power supply is not supplied to the main board 40 and the sub-board 50 through the power circuit 62. In the following description, "power supplied from the external power supply through the power circuit 62" may be referred to as "power supplied from the power circuit 62". Similarly, in the following description, "power supplied from the external power supply is not supplied through the power circuit 62" may be referred to as "power not supplied from the power circuit 62".

The power supply board 60 is provided with a backup power supply 63 as a memory retention power supply. The backup power supply 63 may be, for example, an electric double layer capacitor. The backup power supply 63 is connected to the power supply circuit 62. The backup power supply 63 is supplied with power from the power supply circuit 62. When the supplied power drops or when power is not being supplied from the power supply circuit 62, the power of the backup power supply 63 is supplied to the main RWM 43 of the main board 40 and the sub-RWM 53 of the sub-board 50. The main RWM 43 and the sub-RWM 53 then retain the memory contents by the power supply from the backup power supply 63. In addition, in this embodiment, the main RWM 43 and the sub-RWM 53 correspond to a memory unit that stores and retains information. That is, in this embodiment, the processing unit has a memory unit that stores and retains information. In this way, the main RWM 43 and the sub RWM 53 are configured to be able to store and hold at least a portion of the information stored in the main RWM 43 and the sub RWM 53 using power supplied from the backup power supply 63, even if the power switch 61 is in the off state. In other words, in this embodiment, the memory unit is configured to be able to store and hold at least a portion of the information stored in the memory unit using power supplied from the memory retention power supply, even if the power switch is in the off state.

Next, the monitoring board 70 will be described.
The monitoring board 70 includes a conversion circuit 71. The conversion circuit 71 is connected to the power plug PG. The conversion circuit 71 has a function of converting the voltage of the power supplied from the external power source to a predetermined voltage. The power whose voltage has been converted in the conversion circuit 71 is supplied to a monitoring unit 72 and an auxiliary power source 73, which will be described later. That is, the power from the external power source is supplied to the monitoring unit 72 and the auxiliary power source 73 via the conversion circuit 71. This power from the external power source is supplied to the monitoring unit 72 and the auxiliary power source 73 without passing through the power switch 61.

The monitoring board 70 includes a monitoring unit 72. The monitoring unit 72 is connected to the conversion circuit 71. That is, the monitoring unit 72 is connected to the power plug PG via the conversion circuit 71. Details will be described later, but the monitoring unit 72 is configured to be able to monitor the state of the power switch 61 and the state of power supply to the main board 40 and the sub-board 50. That is, the slot machine 10 includes a monitoring unit that monitors the state of the power switch and the state of power supply to the processing unit. The monitoring unit 72 also includes a monitoring CPU 81, a monitoring ROM 82, and a monitoring RWM 83. The monitoring CPU 81 executes a monitoring control program to perform various processes. The monitoring ROM 82 stores the monitoring control program and the like. The monitoring RWM 83 is configured to store various information that can be rewritten as necessary. The information stored in the monitoring RWM 83 includes, for example, flags, counters, and timers.

The monitoring board 70 is equipped with an auxiliary power supply 73. The auxiliary power supply 73 may be, for example, an electric double layer capacitor. The auxiliary power supply 73 is connected to the power plug PG via the conversion circuit 71. When the power plug PG is connected to an external power supply, power is supplied to the monitoring unit 72 and the auxiliary power supply 73. At this time, power is supplied to the monitoring unit 72 and the auxiliary power supply 73 without going through the power switch 61. In addition, when the power plug PG is connected to an external power supply and the power switch 61 is in an on state, power is supplied from the power supply circuit 62 to the monitoring unit 72. In addition, the auxiliary power supply 73 is connected to the monitoring unit 72. When the power plug PG is not connected to the external power supply, the power of the auxiliary power supply 73 is supplied to the monitoring unit 72. The monitoring CPU 81 of the monitoring unit 72 performs various processes by the power supply from the auxiliary power supply 73. In addition, the monitoring RWM 83 of the monitoring unit 72 stores and holds the memory contents by the power supply from the auxiliary power supply 73. In this way, the monitoring unit 72 is configured to receive power from the auxiliary power supply 73 even when the power switch 61 is off and the power plug PG is not connected to an external power source.

In this specification, "when power supply is started" means, for example, when the power switch 61 is turned on while the power plug PG is connected to an external power source, and power supply from the power supply circuit 62 to the main board 40 and the sub-board 50 is started. Therefore, in this specification, "when power supply is started" does not mean when the power plug PG is connected to an external power source while the power switch 61 is off, and power supply to the monitoring unit 72 and the auxiliary power source 73 is started. Similarly, in this specification, "when power supply is stopped" means, for example, when the power switch 61 is turned off while the power plug PG is connected to an external power source, and power supply from the power supply circuit 62 to the main board 40 and the sub-board 50 is stopped.

Next, the main board 40 will be described.
The main board 40 includes a main CPU 41, a main ROM 42, and a main RWM 43. The main CPU 41 executes a main control program to perform various processes. The main ROM 42 stores the main control program, a lottery table used in a predetermined lottery, and a judgment value. The main RWM 43 is configured to be able to store various information that is appropriately rewritten during operation of the slot machine 10. Examples of information stored in the main RWM 43 include flags, counters, and timers. The main board 40 is configured to be able to generate random numbers. The random numbers may be hardware random numbers or software random numbers.

The reel sensors SE1 to SE3 and the insertion sensor SE4 are connected to the main board 40. The main CPU 41 is configured to be able to input the detection signals output by the various sensors SE1 to SE4 via a port not shown. The actuators of the reels 16a to 16c are connected to the main board 40. The main CPU 41 is configured to be able to control the operation of the actuators of the reels 16a to 16c via a drive circuit not shown. The door opening sensor KS is connected to the main board 40. The main CPU 41 is configured to be able to input the detection signal output by the door opening sensor KS via a port not shown. The locking operation sensor SS is connected to the main board 40. The main CPU 41 is configured to be able to input the detection signal output by the locking operation sensor SS when the locking unit SJ is operated counterclockwise via a port not shown.

The bet button 18, the settlement button 19, the start lever 20, and the stop buttons 21-23 are connected to the main board 40. The main CPU 41 is configured to be able to input detection signals output by the bet button 18, the settlement button 19, the start lever 20, and the stop buttons 21-23 via a port not shown. The information panel 30 is connected to the main board 40. The main CPU 41 is configured to be able to control the display content of the information panel 30 via a drive circuit not shown. The hopper unit HU is connected to the main board 40. The main CPU 41 is configured to be able to control the hopper unit HU via a drive circuit not shown.

The main board 40 is connected to the set value switch 45. The main CPU 41 is configured to be able to input a detection signal, which is output when the set value switch 45 is operated, via a port not shown. The set value switch 45 is configured to be able to be operated using a specified key. In the following description, when it is said that the "set value switch 45 is operated," it means that the set value switch 45 is operated using a specified key. The set value switch 45 is provided on the rear side (back side) of the front door 12. In other words, the set value switch 45 can be operated by opening the front door 12.

The set value can be set by operating the set value switch 45 when power supply starts. The set value is configured in multiple stages, and any one of the set values can be set. That is, the slot machine 10 can change the set value by operating the set value switch 45. In this embodiment, the set values are "1" to "6", and any one of "1" to "6" can be set as the set value. The slot machine 10 is controlled to a set value changeable state in which the set value can be changed by operating the set value switch 45 when power supply starts. In the slot machine 10, the set value selected as the set value to be set can be changed one step at a time by operating the start lever 20 in the set value changeable state. Then, in the slot machine 10, the set value selected when the operation of the set value switch 45 is completed in the set value changeable state is set as the set value.

In the slot machine 10, various lotteries are held under the winning probability based on the setting value. In the slot machine 10, the advantageous degree differs depending on the setting value, and the machine payout rate differs. For example, in the slot machine 10, the probability that various roles are allowed to win in the role lottery differs depending on the setting value. In addition, for example, in the slot machine 10, the probability that a transition to an advantageous zone is determined when in the first normal state differs depending on the setting value. Also, for example, in the slot machine 10, the probability that a transition to the first advantageous state is determined when in the second normal state differs depending on the setting value. For example, in the slot machine 10, the probability that a transition to the second advantageous state is determined when transitioning from the second normal state to the first advantageous state differs depending on the setting value. In the slot machine 10, the probability of being controlled to an advantageous state differs depending on the setting value, and therefore the frequency of being controlled to an advantageous state differs depending on the setting value. Incidentally, in the slot machine 10, the machine payout rate is higher and the advantageous degree is higher in the order of setting value "1" < setting value "2" < setting value "3" < setting value "4" < setting value "5" < setting value "6". In the slot machine 10, when at least one of the setting values "4" to "6" is set, it is easier to control the game to an advantageous state than when one of the setting values "1" to "3" is set.

Here, we will explain the winning numbers and the role lottery table used in the internal lottery to determine the winning number from among multiple winning numbers among the lottery tables stored in the main ROM 42. The internal lottery to determine the winning number is a "role lottery." The winning number determined in the role lottery is also called the condition device combination. For this reason, the role lottery can also be called a "condition device combination lottery." In the following explanation, "a specific winning number is determined in the role lottery" may be expressed as "a specific winning number is won in the role lottery," and the "winning number determined in the role lottery" may be expressed as "the winning number that was won."

The winning number is control information in which one or more symbol combinations are defined as symbol combinations that can be derived (displayed) in a variable game. In other words, the winning number is a condition device identifier in which one or more roles are defined as roles that can result in a win in a variable game. The winning numbers in this embodiment include, for example, winning numbers that allow a cherry role to win, winning numbers that allow a watermelon role to win, winning numbers that allow a bell role to win, and winning numbers that allow a replay role to win.

Among the winning numbers in the slot machine 10 that allow the winning of a bell role, there are winning numbers that allow the winning of a one-coin role in addition to the bell role. The winning numbers that allow the winning of a bell role and a one-coin role include winning numbers in which the operation sequence of the stop button to win the bell role is different from the operation sequence of the stop button to win the one-coin role. For example, the winning numbers that allow the winning of a bell role and a one-coin role include winning numbers that win the bell role when the stop button is operated in a predetermined operation sequence, but win the one-coin role when the stop button is operated in an operation sequence different from the predetermined operation sequence.

In the following explanation, the case where a winning number that allows the cherry role to win in the role lottery is drawn is referred to as "the case where the cherry role is allowed to win." Note that the case where the cherry role is allowed to win corresponds to the lottery result of the role lottery being "the lottery result that allows the cherry role to win." Also, in the following explanation, the case where a winning number that allows the watermelon role to win in the role lottery is drawn is referred to as "the case where the watermelon role is allowed to win." Note that the case where the watermelon role is allowed to win corresponds to the lottery result of the role lottery being "the lottery result that allows the watermelon role to win." Similarly, in the following explanation, the case where a winning number that allows the bell role to win in the role lottery is drawn is referred to as "the case where the bell role is allowed to win." Note that the case where the bell role is allowed to win corresponds to the lottery result of the role lottery being "the lottery result that allows the bell role to win." The winning numbers that allow the winning of the bell role here include winning numbers that allow the winning of the bell role and the one-piece role. In addition, in the following explanation, the case where a winning number that allows the winning of a replay role is won in the role lottery is referred to as "the case where the winning of a replay role is allowed." The case where the winning of a replay role is allowed corresponds to the result of the role lottery being "the lottery result that allows the winning of a replay role."

The main ROM 42 stores a role selection table that is referenced for each set value. In the role selection table, the value of the random number used in the role selection (hereinafter referred to as the role selection random number) for the possible winning number is allocated in a predetermined number from within the range of values that the random number can take. In the slot machine 10, if none of the winning numbers are selected in the role selection, that is, if the role is not allowed to win, the result of the role selection is a "miss." If the result of the role selection is a "miss," the symbol combination for which a prize is determined based on the result of the role selection is not derived on the pay line YL.

Next, the sub-substrate 50 will be described in detail.
The sub-board 50 includes a sub-CPU 51, a sub-ROM 52, and a sub-RWM 53. For example, the sub-CPU 51 executes a sub-control program to perform various processes (for example, processes related to performance). The sub-ROM 52 stores the sub-control program, a lottery table used in the lottery, and a judgment value. The sub-ROM 52 stores light emission performance data related to the light emission performance of the decorative lamp 13. The sub-ROM 52 stores sound performance data related to the sound performance of the speaker 14. The sub-ROM 52 stores display performance data related to the display performance of the performance display device 15. The sub-RWM 53 is configured to be able to store various information that is appropriately rewritten during the operation of the slot machine 10. The information stored by the sub-RWM 53 includes, for example, a flag, a counter, and a timer. The sub-board 50 is configured to be able to generate random numbers. The random numbers may be hardware random numbers or software random numbers.

The decorative lamps 13, the speaker 14, and the performance display device 15 are connected to the sub-board 50. The sub-CPU 51 is configured to be able to control the decorative lamps 13, the speaker 14, and the performance display device 15 via a drive circuit (not shown). The up button B1 and the down button B2 are connected to the sub-board 50. The main CPU 41 is configured to be able to input the detection signals output by the up button B1 and the down button B2 via a port (not shown).

The sub-board 50 is connected to an operable changeover switch SW. The changeover switch SW is an operating means that can set one of a total of eight stages, from stage 1 to stage 8. In this embodiment, the changeover switch SW corresponds to the operable changeover operating means. The sub-CPU 51 is configured to be able to input a control signal that can identify the stage set by the changeover switch SW via a port. The changeover switch SW is provided on the rear side (back side) of the front door 12. In other words, the changeover switch SW can be operated by opening the front door 12.

Regardless of which volume level is set by operating the up button B1 and the down button B2, when the changeover switch SW is operated to change the level, the volume level is changed to the level set by operating the changeover switch SW. In the slot machine 10, when power supply is resumed, the volume level becomes the level set by the changeover switch SW, regardless of the volume level when power supply was stopped. In this embodiment, the volume level set by the changeover switch SW corresponds to the specific volume. Therefore, in this embodiment, the configuration is such that it is possible to switch the volume to be the specific volume from among multiple volume levels by operating the switching operation means. In this embodiment, there are multiple volume levels including the specific volume.

Next, the process performed when the power supply is stopped will be described.
When the main CPU 41 receives a power-off signal, the main CPU 41 performs a main power-off process. In the main power-off process, the main CPU 41 stores and holds, as backup information, information such as a register and a stack pointer in the main RWM 43 in addition to various information stored in the main RWM 43. Backup information includes, for example, information that can identify a game state. For example, by storing and holding the stack pointer, the main CPU 41 can resume processing from the middle when power supply is resumed after the power supply is stopped during processing. In addition, the main CPU 41 calculates a checksum of the main RWM 43 and stores the checksum in the main RWM 43. Furthermore, the main CPU 41 sets a backup flag in the main RWM 43. Thereafter, the main CPU 41 prohibits access to the main RWM 43. After the power supply is stopped, power is supplied from the backup power source 63 to the main RWM 43, and some or all of the information stored in the main RWM 43 when the power supply is stopped is stored and held as backup information.

Similarly, when the secondary CPU 51 receives a power-off signal, it performs a sub-power-off process. In the sub-power-off process, the secondary CPU 51 stores and holds in the secondary RWM 53, in addition to various information stored in the secondary RWM 53, information such as registers and stack pointers as backup information. Backup information includes, for example, information that can identify the performance state. For example, by storing and holding the stack pointer, the secondary CPU 51 can resume processing from the middle when power supply is resumed after the power supply is stopped during processing. In addition, the secondary CPU 51 calculates a checksum of the secondary RWM 53 and stores the checksum in the secondary RWM 53. Furthermore, the secondary CPU 51 sets a backup flag in the secondary RWM 53. Thereafter, the secondary CPU 51 prohibits access to the secondary RWM 53. After the power supply is stopped, power is supplied from the backup power source 63 to the secondary RWM 53, and some or all of the information stored in the secondary RWM 53 when the power supply is stopped is stored and held as backup information.

Next, the process performed when power supply is started will be described.
When power supply from the power supply circuit 62 is started, the main CPU 41 performs main power recovery processing. In the main power recovery processing, the main CPU 41 performs various settings required when power supply is started. As various settings required when power supply is started, the main CPU 41 prohibits interrupts of interrupt processing, permits access to the storage area of the main RWM 43, and performs initial settings of the peripheral devices and watchdog timer of the main board 40. Next, the main CPU 41 determines whether the set value switch 45 is operated. If the set value switch 45 is operated, the main CPU 41 controls the setting value to a state in which the setting value can be changed. Then, after the setting value changeable state ends, the main CPU 41 performs main initial startup processing. On the other hand, if the set value switch 45 is not operated, the main CPU 41 performs main recovery processing.

When the setting value is changed, the main CPU 41 displays information indicating the setting value selected to be set as the setting value on the payout display unit 37. When the setting value is changeable, the main CPU 41 inputs a detection signal from the start lever 20 and updates the information indicating the setting value selected to be set as the setting value displayed on the payout display unit 37. At this time, the main CPU 41 updates the information indicating the setting value selected to be set as the setting value displayed on the payout display unit 37 in the following order: setting value "1" → setting value "2" → setting value "3" → setting value "4" → setting value "5" → setting value "6" → setting value "1" → setting value "2" ... Then, when the operation of the setting value switch 45 is completed when the setting value is changeable, the main CPU 41 sets the setting value selected to be set as the setting value at that time. Specifically, the main CPU 41 stores information (hereinafter referred to as setting value information) capable of identifying the setting value selected to be set as the setting value in the main RWM 43. For example, when the operation of the set value switch 45 is completed while the payout display section 37 is displaying information indicating the set value selected to be set as the set value, the set value in the slot machine 10 will be set to "3". After setting the set value, the main CPU 41 performs the main initial startup process.

In the main initial startup process, the main CPU 41 erases the backup information stored in the main RWM 43. Then, the main CPU 41 stores the initial information in the main RWM 43 and initializes the storage contents of the main RWM 43. For example, the main CPU 41 sets initial values in the main RWM 43, such as a stack pointer. At this time, the setting value information stored in the main RWM 43 is not initialized. Next, the main CPU 41 stores control information (hereinafter referred to as an initialization command) that can identify that the main initial startup process has been performed in the output buffer. Next, the main CPU 41 sets an interval timer (for example, 4 ms) for the interrupt process and allows the interrupt process. Then, the main CPU 41 ends the main initial startup process. Thereafter, the main CPU 41 performs interrupt processing at predetermined intervals. Note that the control information (control command) stored in the output buffer by the main CPU 41 is output to the sub-board 50 in the next and subsequent interrupt processes. In the following description, "initialization occurs when power supply is started" means that power supply is started and main initial startup processing is performed. In the slot machine 10, if the main initial startup processing is performed normally, the slot machine 10 will be in a state where it is possible to play games after the main initial startup processing is performed.

In the main return process, the main CPU 41 judges whether there is an abnormality in the information stored in the main RWM 43. Specifically, the main CPU 41 checks the backup flag stored in the main RWM 43 when the power supply is stopped, and judges whether the backup flag is normal. The backup flag set in the main RWM 43 is a flag for judging whether the information stored in the main RWM 43 is correct when the power supply is started. In addition, if the backup flag is normal, the main CPU 41 calculates the checksum of the main RWM 43 and judges whether the calculated checksum matches the value of the checksum calculated when the power supply is stopped. Then, if the backup flag is not normal, the main CPU 41 judges the return error state. Similarly, if the checksum calculated when the power supply is started and the checksum calculated when the power supply is stopped do not match, the main CPU 41 judges the return error state. In the slot machine 10, if the return error state occurs, it is not possible to play the game. Therefore, in the case of a recovery error state in the slot machine 10, the power supply is stopped again, and then when the power supply is restarted, the set value switch 45 is operated to perform the main initial startup process and initialize the contents stored in the main RWM 43, thereby making it possible to play the game.

On the other hand, if the checksum calculated when the power supply is started and the checksum calculated when the power supply is stopped match, the main CPU 41 performs main backup processing. In the main backup processing, the main CPU 41 restores the stack pointer before the power supply was stopped. Next, the main CPU 41 stores control information (hereinafter referred to as a return command) that can identify that the main return processing has been performed in the output buffer. Next, the main CPU 41 sets an interval timer (for example, 4 ms) for the interrupt processing. Furthermore, the main CPU 41 restores the contents of the register when the power supply was stopped. After that, the main CPU 41 restores the permission/prohibition (prohibition) of the interrupt processing to the state when the power supply was stopped, sets the address before the power supply was cut off, and returns to the set address. This causes a return based on the backup information. Then, when a return based on the backup information is performed, the main CPU 41 ends the main backup processing. After that, the main CPU 41 performs interrupt processing at predetermined intervals. In the following description, "when power supply is resumed after being stopped" refers to a case where power supply is started and main backup processing is performed. In the slot machine 10, when the main backup processing is performed normally, the slot machine 10 is in a state where it is possible to play games after the main backup processing is performed.

In addition, regardless of whether the main CPU 41 has performed the main initial startup process or the main backup process, it identifies the setting value from the setting value information and stores the control information (hereinafter referred to as the setting value command) capable of identifying the identified setting value in the output buffer.

When power supply from the power supply circuit 62 starts, the secondary CPU 51 performs a sub-power supply recovery process. In the sub-power supply recovery process, the secondary CPU 51 performs various settings (initial settings) required in conjunction with the start of power supply. After performing the initial settings, the secondary CPU 51 waits until an initialization command or a recovery command is input. Note that in this embodiment, the secondary CPU 51 starts up before the main CPU 41. Therefore, when an initialization command or a recovery command is output from the main CPU 41, the secondary CPU 51 is already started up and is in a state of waiting for input of the initialization command or the recovery command.

When an initialization command is input, the secondary CPU 51 performs a sub initial startup process. In the sub initial startup process, the secondary CPU 51 erases the backup information stored in the secondary RWM 53. The secondary CPU 51 also stores the initial information in the secondary RWM 53 and initializes the stored contents of the secondary RWM 53. The secondary CPU 51 then ends the sub initial startup process. When the sub initial startup process is performed, the secondary CPU 51 also controls at least one of the decorative lamps 13, the speaker 14, and the performance display device 15 to execute an initialization performance that suggests or notifies that the main initial startup process has been performed. The initialization performance is executed until the execution time of the initialization performance has elapsed.

When a return command is input, the secondary CPU 51 judges whether there is an abnormality in the information stored in the secondary RWM 53. Specifically, the secondary CPU 51 checks the backup flag stored in the secondary RWM 53 when the power supply is stopped, and judges whether the backup flag is normal. The backup flag set in the secondary RWM 53 is a flag for judging whether the information stored in the secondary RWM 53 is correct when the power supply is started. If the backup flag is normal, the secondary CPU 51 calculates a checksum of the secondary RWM 53, and judges whether the calculated checksum matches the value of the checksum calculated when the power supply was stopped. If the backup flag is not normal, the secondary CPU 51 performs a sub-initial startup process. Similarly, if the checksum calculated when the power supply is started does not match the checksum calculated when the power supply is stopped, the secondary CPU 51 performs a sub-initial startup process.

On the other hand, if the checksum calculated when the power supply is started and the checksum calculated when the power supply is stopped match, the secondary CPU 51 performs sub-backup processing. In the sub-backup processing, the secondary CPU 51 restores the stack pointer before the power supply was stopped. Furthermore, the secondary CPU 51 restores the contents of the register when the power supply was stopped. After that, the secondary CPU 51 sets the address before the power supply was cut off, and returns to the set address. This performs a restoration based on the backup information. Then, once a restoration based on the backup information has been performed, the secondary CPU 51 ends the sub-backup processing.

When the secondary CPU 51 inputs a setting value command, it identifies a setting value that can be identified from the setting value command. The secondary CPU 51 then stores setting value information that can identify the identified setting value in the secondary RWM 53. The secondary RWM 53 stores setting value information regardless of whether the secondary CPU 51 performs the sub-initial startup process or the sub-backup process.

Next, a description will be given of the processing performed by the main CPU 41 after the game becomes playable. For example, the main CPU 41 performs a game progress main processing.
The game progress main process will be described below.

8, in the game progress main process, the main CPU 41 performs a game start set process (step S101). In the game start set process, the main CPU 41 stores information about the game state of the slot machine 10, and erases or updates information in a predetermined storage area in the main RWM 43. Next, the main CPU 41 starts accepting medal bets (step S102). Next, the main CPU 41 checks the game state (step S103). Next, the main CPU 41 determines whether or not the re-play operation is in progress (step S104). The re-play operation corresponds to the time when the re-play is granted. If the re-play operation is not in progress (step S104: NO), the main CPU 41 performs a medal management process to set the number of bets in the current variable game (step S105). When the number of bets is set in step S105, the main CPU 41 stores control information (hereinafter referred to as a multiplication number setting command) that can specify that the number of bets has been set in the output buffer. Note that the number of bets that has been set can also be specified from the multiplication number setting command. In step S105, when the main CPU 41 inputs a detection signal from the bet button 18, it adds the number of bets stored in the main RWM 43 to the specified bet number X, and subtracts the credits stored in the main RWM 43 by the added amount. Also, in step S105, when the main CPU 41 inputs a detection signal from the insertion sensor SE4, it increases the number of bets by 1. At this time, if the number of bets has reached the specified bet number X, the main CPU 41 adds 1 to the credits stored in the main RWM 43 and updates the credits. Furthermore, at this time, if the credits have reached the credit upper limit, the main CPU 41 drives the hopper unit HU to pay out one medal.

When the replay is activated (step S104: YES), or when the processing of step S105 is completed, the main CPU 41 determines whether the number of bets in the current variable game matches the specified number of bets X that allows the variable game to be started (step S106). When the replay is activated (step S104: YES), the main CPU 41 sets the number of bets in the previous variable game in the main RWM 43 again as the number of bets in the current variable game. Even if the number of bets is set, information that can identify whether the replay is activated is stored in the main RWM 43, so that the main CPU 41 can identify whether the replay is activated by referring to the information. In this embodiment, the specified number of bets X can also be said to be the number of bets required to play one variable game. In the slot machine 10, for example, the specified number of bets X is not different depending on the game state, but is the same. However, the specified number of bets X may be different depending on the game state. For example, the specified number of bets X may be different in a normal state and in an advantageous state. In this way, when the specified number of bets X is made different depending on the gaming state, the main CPU 41 performs the process of step S106 using the specified number of bets X according to the gaming state.

If the number of bets does not match the specified number of bets X (step S106: NO), the main CPU 41 proceeds to the process of step S103. That is, in the process of step S106, the main CPU 41 determines whether the variable game can be started. On the other hand, if the number of bets in the current variable game matches the specified number of bets X (step S106: YES), the main CPU 41 determines whether a start operation using the start lever 20 has been accepted (step S107). In this embodiment, the situation in which a replay has not been activated between the end of the process of step S102 and the processing of step S106 is judged to be positive (step S104: NO) corresponds to a situation in which the number of bets can be set.

In the process of step S107, the main CPU 41 makes a positive determination if a detection signal is input from the start lever 20, and makes a negative determination if a detection signal is not input from the start lever 20. If the start operation has not been accepted (step S107: NO), the main CPU 41 proceeds to the process of step S103. On the other hand, if the start operation has been accepted (step S107: YES), the main CPU 41 performs a game number subtraction process (step S108). When the main CPU 41 accepts the start operation, it stores control information capable of identifying the start of a variable game (hereinafter referred to as a variable game start command) in the output buffer.

In the game number subtraction process, the main CPU 41 performs a first game number subtraction process, a second game number subtraction process, and a third game number subtraction process. In the game number subtraction process, the main CPU 41 performs the first game number subtraction process, performs the second game number subtraction process after completing the first game number subtraction process, and performs the third game number subtraction process after completing the second game number subtraction process. Then, in the game number subtraction process, the main CPU 41 returns to the game progress main process after completing the third game number subtraction process.

In the first game number subtraction process, the main CPU 41 refers to the value of the game state flag stored in the main RWM 43 and determines whether the current game state is the first advantageous state. If it is not the first advantageous state, the main CPU 41 ends the first game number subtraction process. On the other hand, if it is the first advantageous state, the main CPU 41 updates the remaining pseudo bonus stay count stored in the main RWM 43 by subtracting 1. The remaining pseudo bonus stay count corresponds to the remaining number of variable games in which it is possible to stay in the first advantageous state. Thereafter, the main CPU 41 ends the first game number subtraction process.

In the second game number subtraction process, the main CPU 41 refers to the value of the game state flag and determines whether the current game state is the second advantageous state. If it is not the second advantageous state, the main CPU 41 ends the second game number subtraction process. On the other hand, if it is the second advantageous state, the main CPU 41 updates the remaining number of stays stored in the main RWM 43 by subtracting 1. The remaining number of stays corresponds to the remaining number of variable games in which it is possible to stay in the second advantageous state. Thereafter, the main CPU 41 ends the second game number subtraction process.

In the third game number subtraction process, the main CPU 41 refers to the value of the game state flag and determines whether the current game state is the second normal state or the advantageous state. If it is neither the second normal state nor the advantageous state, the main CPU 41 ends the third game number subtraction process. On the other hand, if it is either the second normal state or the advantageous state, the main CPU 41 updates the advantageous upper limit value stored in the main RWM 43 by subtracting 1. The advantageous upper limit value is the value until the end condition of the advantageous period is met, and the end condition of the advantageous period is met when the advantageous upper limit value reaches 0. Thereafter, the main CPU 41 ends the third game number subtraction process.

After completing the game number subtraction process, the main CPU 41 performs a role lottery process to determine a winning number as a role lottery (step S109). In the role lottery process, the main CPU 41 acquires the value of the role lottery random number. The main CPU 41 also refers to the setting value information to identify the set setting value. The main CPU 41 then selects a role lottery table corresponding to the identified setting value. The main CPU 41 performs a role lottery by referring to the selected role lottery table based on the acquired value of the role lottery random number. Specifically, the main CPU 41 determines the winning number to which the acquired value of the role lottery random number is assigned. Note that if the value of the role lottery random number is not assigned to a winning number that allows the winning of a pattern combination with a predetermined prize, the lottery result of the role lottery is a "lose". In this embodiment, the main CPU 41 performs the role lottery process to realize a function as a role lottery means for performing a role lottery.

In addition, in the role selection process, the main CPU 41 stores information capable of identifying the result of the role selection (hereinafter referred to as winning information) in the main RWM 43. The main CPU 41 also stores control information capable of identifying the result of the role selection (hereinafter referred to as winning information command) in the output buffer. After storing the winning information command in the output buffer, the main CPU 41 ends the role selection process and returns to the game progress main process.

When the role selection process is completed, the main CPU 41 performs advantageous selection process (step S110). In the advantageous selection process, the main CPU 41 performs advantageous zone transition selection process, first advantageous transition selection process, second advantageous transition selection process, ceiling determination process, and additional selection process. In the advantageous selection process, the main CPU 41 performs advantageous zone transition selection process, performs the first advantageous transition selection process after completing the advantageous zone transition selection process, and performs the second advantageous transition selection process after completing the first advantageous transition selection process. Furthermore, in the advantageous selection process, the main CPU 41 performs the ceiling determination process after completing the second advantageous transition selection process, and performs the additional selection process after completing the ceiling determination process. Then, in the advantageous selection process, the main CPU 41 returns to the game progress main process after completing the additional selection process.

In the advantageous zone transition lottery process, the main CPU 41 refers to the value of the game state flag and determines whether the current game state is the first normal state. If it is not the first normal state, the main CPU 41 ends the advantageous zone transition lottery process. On the other hand, if it is the first normal state, the main CPU 41 performs an advantageous zone transition lottery based on the lottery result of the role lottery. The main CPU 41, for example, acquires the value of a random number generated in the main board 40, and refers to a predetermined lottery table based on the acquired random number value to perform an advantageous zone transition lottery that can determine a transition to an advantageous zone. The probability that a transition to an advantageous zone is determined in the advantageous zone transition lottery varies depending on the set value and the lottery result of the role lottery. For example, in the slot machine 10, when the lottery result of the role lottery is the same, the probability that a transition to an advantageous zone is determined is high in the following order: setting value "1" < setting value "2" < setting value "3" < setting value "4" < setting value "5" < setting value "6". The probability that a transition to an advantageous zone will be determined in the advantageous zone transition lottery may be configured to vary depending on either the set value or the result of the role lottery. If a transition to an advantageous zone is not determined in the advantageous zone transition lottery, the main CPU 41 ends the advantageous zone transition lottery process. On the other hand, if a transition to an advantageous zone is determined in the advantageous zone transition lottery, the main CPU 41 stores advantageous transition permission information in the main RWM 43. Furthermore, the main CPU 41 stores control information (hereinafter referred to as an advantageous permission command) capable of identifying that a transition to an advantageous performance state has been determined in the output buffer, and ends the advantageous transition lottery process.

In the first advantageous transition lottery process, the main CPU 41 refers to the value of the game state flag and determines whether the current game state is the second normal state or the second advantageous state. If it is not the second normal state or the second advantageous state, the main CPU 41 terminates the first advantageous transition lottery process. On the other hand, if it is the second normal state or the second advantageous state, the main CPU 41 conducts a first advantageous transition lottery based on the lottery result of the role lottery. The main CPU 41, for example, acquires the value of a random number generated within the main board 40, and refers to a predetermined lottery table based on the acquired random number value to conduct a first advantageous transition lottery that can determine a transition to the first advantageous state. The probability that a transition to the first advantageous state will be determined in the first advantageous transition lottery varies depending on the set value that has been set and the lottery result of the role lottery. For example, in the slot machine 10, when the lottery results of the role lottery are the same, the probability of determining a transition to the first advantageous state is higher in the order of setting value "1" < setting value "2" < setting value "3" < setting value "4" < setting value "5" < setting value "6". The probability of determining a transition to the first advantageous state in the first advantageous transition lottery may be configured to be different depending on one of the set setting value and the lottery result of the role lottery. In addition, the probability of determining a transition to the first advantageous state in the first advantageous transition lottery differs between when the second normal state is in effect and when the second advantageous state is in effect. Specifically, the probability of determining a transition to the first advantageous state in the first advantageous transition lottery when the second advantageous state is in effect is higher than the probability of determining a transition to the first advantageous state in the first advantageous transition lottery when the second normal state is in effect. If a transition to the first advantageous state is not determined in the first advantageous transition lottery, the main CPU 41 ends the first advantageous transition lottery process. On the other hand, if a transition to the first advantageous state is determined in the first advantageous transition lottery, the main CPU 41 stores first advantageous permissive information capable of identifying that a transition to the first advantageous state has been determined in the main RWM 43. Furthermore, the main CPU 41 stores control information capable of identifying that a transition to the first advantageous state has been determined (hereinafter, referred to as a first advantageous permissive command) in the output buffer, and ends the first advantageous transition lottery process.

In the second advantageous transition lottery process, the main CPU 41 refers to the value of the game state flag and determines whether the current game state is the first advantageous state. If it is not the first advantageous state, the main CPU 41 ends the second advantageous transition lottery process. On the other hand, if it is the first advantageous state, the main CPU 41 determines whether second advantageous allowance information capable of identifying that a transition to the second advantageous state has been decided is stored in the main RWM 43. Then, if the number of remaining stays stored in the main RWM 43 is 1 or more, the main CPU 41 ends the second advantageous transition lottery process. On the other hand, if the second advantageous allowance information is not stored, the main CPU 41 performs a second advantageous transition lottery based on the lottery result of the role lottery. For example, the main CPU 41 acquires the value of a random number generated in the main board 40, and refers to a predetermined lottery table based on the acquired value of the random number, and performs a second advantageous transition lottery capable of determining a transition to the second advantageous state. The probability that a transition to the second advantageous state is determined in the second advantageous transition lottery varies depending on the set value that has been set and the lottery result of the role lottery. For example, in the slot machine 10, when the lottery results of the role lottery are the same, the probability of determining a transition to the second advantageous state is higher in the order of setting value "1" < setting value "2" < setting value "3" < setting value "4" < setting value "5" < setting value "6". The probability of determining a transition to the second advantageous state in the second advantageous transition lottery may be configured to differ depending on either the set setting value or the lottery result of the role lottery. If a transition to the second advantageous state is not determined in the second advantageous transition lottery, the main CPU 41 ends the second advantageous transition lottery process. On the other hand, if a transition to the second advantageous state is determined in the second advantageous transition lottery, the main CPU 41 stores the second advantageous allowance information in the main RWM 43. Furthermore, the main CPU 41 stores control information (hereinafter referred to as the second advantageous allowance command) capable of identifying that a transition to the second advantageous state has been determined in the output buffer, and ends the second advantageous transition lottery process.

In the ceiling determination process, the main CPU 41 refers to the value of the game state flag and determines whether the current game state is the second normal state. If it is not the second normal state, the main CPU 41 ends the ceiling determination process. On the other hand, if it is the second normal state, the main CPU 41 adds 1 to the normal execution count stored in the main RWM 43 and updates the normal execution count. The normal execution count corresponds to the number of variable games executed in the second normal state without being controlled to the advantageous state. The main CPU 41 determines whether the updated normal execution count has reached the ceiling count stored in the main RWM 43. If the normal execution count has not reached the ceiling count, the main CPU 41 ends the ceiling determination process. On the other hand, if the normal execution count has reached the ceiling count, the main CPU 41 stores the first advantageous acceptance information in the main RWM 43. Furthermore, the main CPU 41 stores the first advantageous acceptance command in the output buffer and ends the ceiling determination process.

In the add-on lottery process, the main CPU 41 refers to the value of the game state flag and determines whether the current game state is the second advantageous state. If it is not the second advantageous state, the main CPU 41 ends the add-on lottery process. On the other hand, if it is the second advantageous state, the main CPU 41 performs an add-on lottery based on the lottery result of the role lottery. The main CPU 41, for example, acquires the value of a random number generated in the main board 40, and refers to a predetermined lottery table based on the acquired random number value, and performs an add-on lottery to determine whether to add or not to add depending on the acquired random number value. In addition, in this embodiment, when it is decided to add, the number of times to add (so-called add-on number) is also determined. The "add-on" here corresponds to increasing the remaining number of stays, which corresponds to the remaining number of variable games that can stay in the second advantageous state, that is, extending the period controlled in the second advantageous state. And the "number of add-ons" corresponds to the number of times to increase the remaining number of stays, that is, the number of times to be added to the remaining number of stays. However, if the remaining number of stays stored in the main RWM 43 exceeds the advantageous upper limit value stored in the main RWM 43, the main CPU 41 does not perform an add-on lottery in the add-on lottery process and ends the add-on lottery process. If it is decided to add on in the add-on lottery, the main CPU 41 adds the decided add-on number to the remaining number of stays and updates the remaining number of stays. Furthermore, the main CPU 41 stores control information capable of identifying the number of add-on times (hereinafter referred to as an add-on number command) in the output buffer and ends the add-on lottery process. In this embodiment, adding on is equivalent to granting a bonus. Therefore, in this embodiment, the main CPU 41 adds the number of add-on times to the number of stays, thereby realizing a function as a bonus granting means that grants a bonus.

When the advantageous lottery process is completed, the main CPU 41 performs a stagnation effect process (step S111). In the stagnation effect process, a process may be executed to execute a reel effect in which the reels 16a to 16c stop spinning after the reels 16a to 16c have rotated. The specific control in the stagnation effect process will be described later.

When the stagnation effect processing is completed, the main CPU 41 performs the instruction information determination processing (step S112). In the instruction information determination processing, when the main CPU 41 is in an advantageous state and the winning number that allows the winning of the bell role and the one-piece role is won in the role lottery, the main CPU 41 determines an instruction number corresponding to the operation sequence for winning the bell role. In addition, the main CPU 41 stores control information (hereinafter referred to as an instruction information command) that can identify the determined instruction information in the output buffer, ends the instruction information determination processing, and returns to the game progress main processing. In the instruction information displayed on the payout display unit 37 in this embodiment, there is instruction information corresponding to each operation sequence (pressing order) of the stop button. In addition, in the instruction information determination processing, the main CPU 41 refers to the value of the game state flag to identify the current game state.

After completing the instruction information determination process, the main CPU 41 performs an instruction information display process (step S113). When the instruction information is determined in the instruction information determination process, the main CPU 41 controls the payout display unit 37 so that the determined instruction information is displayed. The main CPU 41 controls the payout display unit 37 so that the instruction information is displayed until the variable game ends. Details will be described later, but since the reels 16a to 16c rotate between the end of step S113 and the end of the variable game, the navigation effect is executed when the reels are rotating. That is, in this embodiment, when the reels are rotating during the execution of the variable game, the notification means can execute an effect related to the operation of the stop operation means. Note that, if the instruction information is not determined in the instruction information determination process, the main CPU 41 ends the instruction information display process and returns to the game progress main process. In this way, in this embodiment, the main CPU 41 controls the payout display unit 37 as the notification means, thereby realizing the function as the notification control means that controls the notification means. That is, in this embodiment, the main control unit has the function as the notification control means. In this embodiment, the processing unit also functions as a notification control means.

When the instruction information display process is completed, the main CPU 41 determines whether the wait time has elapsed (step S114). If the wait time has not elapsed (step S114: NO), the main CPU 41 waits until the wait time has elapsed. If the wait time has elapsed (step S114: YES), the main CPU 41 controls the actuators of the reels 16a to 16c so that the reels 16a to 16c start to rotate (step S115). In the slot machine 10, the variable game is started by starting the rotation of the reels 16a to 16c in step S115. Incidentally, in the slot machine 10, rotation control is performed in the interrupt process to accelerate and maintain the rotation of the reels 16a to 16c. When the speed at which the reels 16a to 16c rotate reaches a constant speed in the interrupt process, the speed at which the reels 16a to 16c rotate is maintained at the constant speed.

In step S115, if the main CPU 41 has not performed the process of executing a reel effect in the stagnation effect process of step S111, it starts the rotation of all reels 16a to 16c simultaneously or approximately simultaneously. On the other hand, in step S115, if the main CPU 41 has performed the process of executing a reel effect in the stagnation effect process of step S111, it determines the order in which to start the rotation of the reels 16a to 16c, and starts the rotation of the reels 16a to 16c in the determined order. This results in a time difference in the timing at which the rotation of the reels 16a to 16c starts. Note that the order in which the rotation of the reels 16a to 16c starts may be configured to be determined from multiple orders, or may be a single order that has been determined in advance.

Next, the main CPU 41 determines whether the speed at which the reels 16a to 16c rotate has reached a constant speed (step S116). If the speed at which the reels 16a to 16c rotate has not reached a constant speed (step S116: NO), the main CPU 41 waits until the speed at which the reels 16a to 16c rotate reaches a constant speed. If the speed at which the reels 16a to 16c rotate has reached a constant speed (step S116: YES), the main CPU 41 determines whether a stop operation has been received from any of the stop buttons 21 to 23 (step S117). In the process of step S117, the main CPU 41 makes a positive determination if a detection signal has been input from any of the stop buttons 21 to 23, whereas it makes a negative determination if a detection signal has not been input from any of the stop buttons 21 to 23. If a stop operation has not been received (step S117: NO), the main CPU 41 proceeds to the process of step S116. This causes the main CPU 41 to wait until it receives a stop operation when the reels 16a to 16c are rotating at a constant speed.

On the other hand, if a stop operation is received (step S117: YES), the main CPU 41 executes a reel stop process to stop the rotation of the reel corresponding to the stop button that received the detection signal (step S118). That is, the main CPU 41 controls the actuator in response to the stop operation to stop the symbols on the reel corresponding to the stop operation. To explain in detail, the main CPU 41 searches for symbols that can be stopped on the effective line YL from among symbols located within a predetermined pull-in range (for example, 4 symbols) based on the lottery result of the role selection and the operation mode of the stop buttons 21 to 23 (operation sequence and operation position (operation timing)). Then, the main CPU 41 controls the actuator so that the searched symbols are stopped on the effective line YL. By performing such reel stop control regarding the stop operation of the reels 16a to 16c, the main CPU 41 stops the symbol combination corresponding to the winning number and the operation mode of the stop buttons on the effective line YL. Furthermore, in the processing of step S118, when the main CPU 41 receives a detection signal from one of the stop buttons 21 to 23, it stores in the output buffer control information (hereinafter referred to as an operation command) that can identify the stop button that received the detection signal.

Next, the main CPU 41 determines whether all of the reels 16a to 16c have stopped (step S119). If some of the reels 16a to 16c have not stopped (step S119: NO), the main CPU 41 proceeds to the process of step S116. On the other hand, if all of the reels 16a to 16c have stopped (step S119: YES), the main CPU 41 performs a display pattern determination process to determine the symbol combination stopped on the pay line YL (step S120). In the display pattern determination process, the main CPU 41 determines whether a symbol combination (role) that determines a prize is stopped on the pay line YL, and if a symbol combination (role) that determines a prize is stopped on the pay line YL, the main CPU 41 determines the type of the symbol combination. Then, if a symbol combination that determines a prize is stopped, that is, if a role is won, the main CPU 41 stores control information (hereinafter referred to as a winning command) that can identify the winning role in the output buffer. Also, in step S120, if a symbol combination for which a replay is set as a prize is stopped on the active line YL, the main CPU 41 sets the bet amount in the current variable game as the bet amount again and activates the replay. This results in the replay being awarded as a prize.

Then, the main CPU 41 judges whether to pay out medals to the player (step S121). In the process of step S121, the main CPU 41 judges positive if the payout role is a winning combination, and judges negative if the payout role is not a winning combination. If the medals are to be paid out (step S121: YES), the main CPU 41 executes the medal payout process (step S122). In the medal payout process, the main CPU 41 increases the credits stored in the main RWM 43 by the number of medals to be paid out. At this time, if the credit upper limit number (e.g., 50) is exceeded, the main CPU 41 controls the hopper unit HU so that the number of medals exceeding the credit upper limit number is paid out. In addition, in the medal payout process, the main CPU 41 controls the payout display unit 37 so that the number of medals to be paid out due to the occurrence of a winning combination is displayed. Incidentally, if a pattern combination for which no prize is determined (e.g., a losing stop) is stopped on the pay line YL, no prize is awarded.

If medals are not to be paid out (step S121: NO) and if the medal payout process has ended, the main CPU 41 performs a termination process to end one round of the variable game (step S123). In the termination process, the main CPU 41 stores control information capable of identifying the end of the variable game (hereinafter referred to as the variable game end command) in the output buffer. In this embodiment, the variable game end command is control information capable of identifying whether or not a prize has been won and the winning combination.

In the termination process, the main CPU 41 performs an acquired coin count process, a game state transition process, and a presentation state transition process. First, the acquired coin count process will be described.
In the winning number counting process, the main CPU 41 may update the favorable zone acquisition information capable of identifying the number of game media awarded when in the favorable zone based on the result of the display pattern determination process when in either the second normal state or the favorable state. The favorable zone acquisition information is stored in the main RWM 43. When a bell role is won, the main CPU 41 adds "12" to the favorable zone acquisition information and updates the favorable zone acquisition information. Similarly, when a watermelon role is won, the main CPU 41 adds "2" to the favorable zone acquisition information and updates the favorable zone acquisition information. Note that, when a cherry role is won, the main CPU 41 does not update the favorable zone acquisition information. Similarly, when a replay role is won, the main CPU 41 does not update the favorable zone acquisition information. Also, when a one-piece role is won, the main CPU 41 subtracts "2" from the favorable zone acquisition information and updates the favorable zone acquisition information. Furthermore, if the combination does not win, i.e., if it is a miss, the main CPU 41 subtracts "3" from the advantageous zone acquisition information and updates the advantageous zone acquisition information. When subtracting from the advantageous zone acquisition information, if the value after subtraction is less than 0, the main CPU 41 sets the advantageous zone acquisition information to "0" and updates the advantageous zone acquisition information. The advantageous zone acquisition information is updated to "0" and initialized as the game is controlled to the first normal state. Specifically, the advantageous zone acquisition information is initialized as the first variable game is executed after the game is controlled to the first normal state.

In addition, in the winning number counting process, the main CPU 41 may update the first period winning information that can specify the number of game media awarded when in an advantageous state based on the result of the display pattern determination process when in an advantageous state. The first period winning information is stored in the main RWM 43. When a bell role is won, the main CPU 41 adds "12" to the first period winning information and updates the first period winning information. When a watermelon role is won, the main CPU 41 adds "2" to the first period winning information and updates the first period winning information. Note that when a cherry role is won, the main CPU 41 does not update the first period winning information. Similarly, when a replay role is won, the main CPU 41 does not update the first period winning information. When a one-piece role is won, the main CPU 41 subtracts "2" from the first period winning information and updates the first period winning information. Furthermore, if the combination does not win, i.e., if it is a loss, the main CPU 41 subtracts "3" from the first period acquisition information and updates the first period acquisition information. Note that when subtracting from the first period acquisition information, if the value after subtraction is less than 0, the main CPU 41 sets the first period acquisition information to "0" and updates the first period acquisition information. The first period acquisition information is updated to "0" and initialized as the first normal state is controlled. Specifically, the first period acquisition information is initialized as the first variable game is executed after the first normal state is controlled.

In addition, in the winning number counting process, the main CPU 41 may update the second period winning information that can specify the number of game media awarded when the first advantageous state is in the first advantageous state based on the result of the display pattern determination process. The second period winning information is stored in the main RWM 43. When a bell role is won, the main CPU 41 adds "12" to the second period winning information and updates the second period winning information. Similarly, when a watermelon role is won, the main CPU 41 adds "2" to the second period winning information and updates the second period winning information. Note that, when a cherry role is won, the main CPU 41 does not update the second period winning information. Similarly, when a replay role is won, the main CPU 41 does not update the second period winning information. Also, when a one-piece role is won, the main CPU 41 subtracts "2" from the second period winning information and updates the second period winning information. Furthermore, if the combination does not win, i.e., if it is a loss, the main CPU 41 subtracts "3" from the second period acquisition information and updates the second period acquisition information. Note that when subtracting from the second period acquisition information, if the value after subtraction is less than 0, the main CPU 41 sets the second period acquisition information to "0" and updates the second period acquisition information. The second period acquisition information is updated to "0" and initialized when the game is controlled to the first normal state or the second advantageous state. Specifically, the second period acquisition information is initialized when the first variable game is executed after the game is controlled to the first normal state or the second advantageous state.

Incidentally, the value "12" added to the advantageous zone acquisition information, first period acquisition information, and second period acquisition information when a bell role wins corresponds to the difference between "15", the number of medals awarded by the winning of a bell role, and "3", the number of medals consumed in playing the variable game. The value "2" added to the advantageous zone acquisition information, first period acquisition information, and second period acquisition information when a watermelon role wins corresponds to the difference between "5", the number of medals awarded by the winning of a watermelon role, and "3", the number of medals consumed in playing the variable game. The value "2" subtracted from the advantageous zone acquisition information, first period acquisition information, and second period acquisition information when a single-coin role wins corresponds to the difference between "1", the number of medals awarded by the winning of a single-coin role, and "3", the number of medals consumed in playing the variable game. In the event of a loss, the value "3" that is subtracted from the advantageous zone acquisition information, the first period acquisition information, and the second period acquisition information corresponds to "3 medals", which is the number of medals consumed in playing the variable game.

Next, the game state transition process will be described.
In the game state transition process, the main CPU 41 updates the value of the game state flag and transitions the game state. The main CPU 41 refers to the game state flag to identify the current game state. The main CPU 41 identifies the winning combination based on the result of the display pattern determination process (step S120). When the main CPU 41 updates the value of the game state flag, it stores in the output buffer control information (hereinafter referred to as a game state designation command) that indicates the game state that can be identified from the updated value.

Specifically, in the game state transition process, if advantageous transition permission information is stored in the main RWM 43 during the first game state, that is, if a transition to an advantageous zone has been determined, the main CPU 41 sets the game state flag to a value that can identify the second normal state. The main CPU 41 also determines the ceiling number of times and stores the determined ceiling number of times in the main RWM 43. For example, the main CPU 41 determines the ceiling number of times from among the numbers less than "1500 times", which corresponds to the upper limit number of stays, under a lottery probability according to a set value. Furthermore, the main CPU 41 erases the advantageous transition permission information stored in the main RWM 43.

In addition, when the first advantageous acceptance information is stored in the main RWM 43 while in the second gaming state or the second advantageous state, that is, when a transition to the first advantageous state is decided, the main CPU 41 sets a value that can identify the first advantageous state to the gaming state flag. In addition, the main CPU 41 stores "30 times" in the main RWM 43 as the remaining number of pseudo bonus stays. Furthermore, the main CPU 41 erases the first advantageous acceptance information stored in the main RWM 43.

In addition, when the pseudo bonus remaining number of stays stored in the main RWM 43 reaches 0 during the first advantageous state, that is, when the first advantageous state ends, when the second advantageous allowance information is stored, or when the remaining number of stays is 1 or more, the main CPU 41 sets the game state flag to a value that can identify the second advantageous state. The case where the second advantageous allowance information is stored corresponds to the case where a transition to the second advantageous state is determined by lottery when the second normal state transitions to the first advantageous state. In addition, the case where the remaining number of stays is 1 or more corresponds to the case where a transition is made from the second advantageous state to the first advantageous state. In addition, the main CPU 41 adds "50 times" to the remaining number of stays stored in the main RWM 43 to update the remaining number of stays. Therefore, when a transition is made from the second advantageous state to the first advantageous state, and the first advantageous state ends and the transition is made to the second advantageous state again, an addition of "50 times" is made. Furthermore, if the second advantageous allowance information is stored, the main CPU 41 erases the second advantageous allowance information stored in the main RWM 43. On the other hand, if the pseudo bonus remaining number of stays stored in the main RWM 43 reaches 0 when the first advantageous state is in effect, if the second advantageous allowance information is not stored, and the remaining number of stays is not 1 or more, the main CPU 41 sets the game state flag to a value that can identify the first normal state. In this manner, in this embodiment, if the pseudo bonus remaining number of stays stored in the main RWM 43 reaches 0 when the first advantageous state is in effect, and if the second advantageous allowance information is stored, or if the remaining number of stays is 1 or more, the transition condition is met. On the other hand, in this embodiment, if the pseudo bonus remaining number of stays stored in the main RWM 43 reaches 0 when the first advantageous state is in effect, and if the second advantageous allowance information is not stored, and the remaining number of stays is not 1 or more, the transition condition is not met.

In addition, when the remaining number of stays stored in the main RWM 43 reaches 0 in the second advantageous state, the main CPU 41 sets the game state flag to a value that can identify the first normal state. In addition, when the advantageous upper limit value stored in the main RWM 43 reaches 0 in the second normal state and advantageous state, that is, when the end condition of the advantageous zone is met, the main CPU 41 sets the game state flag to a value that can identify the first normal state. Similarly, when the advantageous zone acquisition information stored in the main RWM 43 reaches 2400 in the second normal state and advantageous state, that is, when the end condition of the advantageous zone is met, the main CPU 41 sets the game state flag to a value that can identify the first normal state. In addition, when the end condition of the advantageous zone is met, and any of the advantageous transition allowance information, the first advantageous allowance information, and the second advantageous allowance information is stored in the main RWM 43, the main CPU 41 erases the information. In this way, in this embodiment, the main control unit can be controlled to a specific state. In this embodiment, the main CPU 41 performs game state transition processing, thereby realizing the function of game state control means.

Next, the presentation state transition process will be described.
In the presentation state transition process, the main CPU 41 updates the value of the presentation state flag and transitions the presentation state. The main CPU 41 refers to the presentation state flag to identify the current presentation state.

In the presentation state transition process, if the game state flag is set to a value that can identify the first normal state or the second normal state, the main CPU 41 sets the presentation state flag to a value that can identify the normal presentation state. Also, if the game state flag is set to a value that can identify the first advantageous state, the main CPU 41 sets the presentation state flag to a value that can identify the pseudo bonus presentation state. If the game state flag is set to a value that can identify the second advantageous state, the main CPU 41 sets the presentation state flag to a value that can identify the advantageous presentation state.

In addition, when the end process is completed in the game progress main process, the main CPU 41 ends the game progress main process related to the execution of one variable game, and returns to the process of step S101 again. As described above, in the slot machine 10, the start operation is triggered to start the rotation of all reels, and the stop operation is triggered to stop the rotation of the reels.

Next, the stagnation effect processing in step S111 will be described.
As shown in FIG. 8, in the stagnation effect processing, the main CPU 41 judges whether or not it is in the second advantageous state (step S201). If it is not in the second advantageous state (step S201: NO), the main CPU 41 ends the stagnation effect processing. On the other hand, if it is in the second advantageous state (step S201: YES), the main CPU 41 judges whether or not it has been decided to add on (step S202). In step S202, the main CPU 41 judges whether or not it has been decided to add on in the add-on lottery processing in the advantageous lottery processing of step S110. If it has been decided to add on (step S202: YES), the main CPU 41 determines the first effect stop pattern (step S203) and proceeds to the processing of step S206. The first effect stop pattern will be explained later.

If it has not been decided to add to the stagnation lottery (step S202: NO), the main CPU 41 performs a stagnation lottery and determines whether the stagnation lottery has been won (step S204). In step S204, the main CPU 41, for example, acquires the value of a random number generated within the main board 40, and refers to a predetermined lottery table based on the acquired random number value, and performs a stagnation lottery according to the acquired random number value. Then, if the stagnation lottery is not won (step S204: NO), the main CPU 41 ends the stagnation performance processing. On the other hand, if the stagnation lottery is won (step S204: YES), the main CPU 41 determines a second performance stop pattern (step S205) and proceeds to the processing of step S206.

Here, the first and second performance stop patterns will be described. In the slot machine 10, when the first performance stop pattern is determined, when all reels stop spinning in the reel performance, a white seven symbol is displayed at each middle stop position of all reels. On the other hand, in the slot machine 10, when the second performance stop pattern is determined, a white seven symbol is displayed at the middle stop position of the reel that has stopped spinning the first and second times, while a white seven symbol is displayed at the lower stop position of the reel that has stopped spinning the third time. In this way, the first performance stop pattern and the second performance stop pattern have different symbol combinations displayed in the display window 12a after the reels rotate in the reel performance. In the slot machine 10, the first performance stop pattern is determined only when an add-on is performed (step S202: YES). Therefore, in the slot machine 10, if a white seven symbol is stopped and displayed at each middle stop position of the reels 16a to 16c that constitute the activated line YL in the reel performance, it can be determined that an add-on is performed. In this embodiment, the symbol combination in which a white seven symbol appears in the middle stop position of each reel corresponds to a specific symbol combination.

In step S206, the main CPU 41 controls the actuators of the reels 16a to 16c so that the reels 16a to 16c start to rotate. Furthermore, in step S206, the main CPU 41 stores in the output buffer control information (hereinafter referred to as a stagnation start command) that can identify that the reel performance has started.

In step S206, the main CPU 41 starts the rotation of all reels 16a to 16c simultaneously or approximately simultaneously. For example, in step S206, the main CPU 41 may determine the order in which the rotation of reels 16a to 16c will start, and start the rotation of reels 16a to 16c in the determined order. Note that the order in which the rotation of reels 16a to 16c will start may be configured to be determined from multiple orders, or may be a single order determined in advance.

Then, the main CPU 41 judges whether the speed at which the reels 16a to 16c rotate has reached a constant speed (step S207). If the speed at which the reels 16a to 16c rotate has not reached a constant speed (step S207: NO), the main CPU 41 waits until the speed at which the reels 16a to 16c rotate reaches a constant speed. If the speed at which the reels 16a to 16c rotate has reached a constant speed (step S207: YES), the main CPU 41 judges whether a stop operation has been received from any of the stop buttons 21 to 23 (step S208). In the process of step S208, the main CPU 41 makes a positive judgment if a detection signal has been input from any of the stop buttons 21 to 23, whereas it makes a negative judgment if a detection signal has not been input from any of the stop buttons 21 to 23. If a stop operation has not been received (step S208: NO), the main CPU 41 waits until a stop operation is received.

On the other hand, when the stop operation is received (step S208: YES), the main CPU 41 executes a rotation stop process to stop the rotation of the reel corresponding to the stop button that received the detection signal (step S209). In the rotation stop process, the main CPU 41 stops the rotation of the reel based on the determined effect stop pattern from the first effect stop pattern and the second effect stop pattern. For example, when the main CPU 41 determines the first effect stop pattern, the main CPU 41 stops the rotation of the reel so that a white seven symbol is displayed at the middle stop position of the reel corresponding to the operated stop button. Also, for example, when the main CPU 41 determines the second effect stop pattern, the main CPU 41 stops the rotation of the reel so that a white seven symbol is displayed at the middle stop position of the reel corresponding to the first and second stop buttons operated. Furthermore, for example, when the main CPU 41 determines the second effect stop pattern, the main CPU 41 stops the rotation of the reel so that a white seven symbol is displayed at the lower stop position of the reel corresponding to the third stop button operated. Furthermore, in step S209, when the main CPU 41 receives a detection signal from one of the stop buttons 21 to 23, it stores control information (hereinafter referred to as a stagnation operation command) capable of identifying the stop button that received the detection signal in the output buffer.

Incidentally, when the main CPU 41 stops the rotation of the reels in step S209, it may do so in a manner different from that in the case of stopping the rotation of the reels in a variable game. For example, when stopping the rotation of the reels in a variable game, the main CPU 41 may stop the rotation of the reels without the reels moving up and down in small increments. On the other hand, for example, when stopping the rotation of the reels in step S209, the main CPU 41 may stop the rotation of the reels so that the reels move up and down in small increments (swaying motion) while stopping the rotation of the reels so that symbols are displayed at each stop position. Note that stopping the rotation of the reels in step S209 corresponds to stopping the rotation of the reels in a reel presentation.

The main CPU 41 then determines whether all of the reels 16a to 16c have stopped (step S210). If some of the reels 16a to 16c have not stopped (step S210: NO), the main CPU 41 proceeds to the process of step S208. On the other hand, if all of the reels 16a to 16c have stopped (step S210: YES), the main CPU 41 stores control information capable of identifying that the reel effect has ended (hereinafter referred to as a stagnation end command) in the output buffer (step S211), and ends the stagnation effect process.

In the slot machine 10, the processing of steps S206 to S211 in the stagnation effect processing is the processing for executing the reel effect. In this embodiment, the processing of steps S206 to S211 in the stagnation effect processing corresponds to freeze control. Thus, in this embodiment, the main CPU 41 performs the processing of steps S206 to S211 in the stagnation effect processing, thereby realizing a function as a freeze control means capable of performing freeze control. That is, in this embodiment, the main control unit has a function as a freeze control means. Also, in this embodiment, the processing unit has a function as a freeze control means. In the following description, the time when the processing of steps S206 to S211 in the stagnation effect processing is performed may be indicated as the time when freeze control is performed. Also, in this embodiment, not limited to the stagnation effect processing, the main CPU 41 controls the rotation and stopping of the reels 16a to 16c, thereby realizing a function as a reel control means for controlling the rotation and stopping of multiple reels. That is, in this embodiment, the main control unit has a function as a reel control means. In this embodiment, the processing unit also functions as a reel control means.

As described above, the main CPU 41 is capable of spinning the multiple reels 16a-16c when freeze control is being performed, and is capable of stopping the rotation of the reel corresponding to the operated stop button when one of the stop buttons 21-23 is operated. That is, in this embodiment, the reel control means is capable of spinning the multiple reels when freeze control is being performed, and is capable of stopping the rotation of the reel corresponding to the operated stop operation means when the stop operation means is operated. In the slot machine 10, when a reel presentation is performed, the multiple reels 16a-16c spin, and the rotation of the reels is stopped by operating the stop buttons 21-23.

In the slot machine 10 of this embodiment, the main CPU 41 may perform settlement processing in addition to the game progress main processing. The main CPU 41 performs settlement processing when a detection signal is input from the settlement button 19. Note that the main CPU 41 does not perform settlement processing during the period in which the main CPU 41 is performing the processing of steps S108 to S123 in the game progress main processing, even if a detection signal is input from the settlement button 19. In other words, the period in which settlement processing can be performed (hereinafter referred to as the settlement processing possible period) is the period in which the main CPU 41 is performing the processing of steps S101 to S107 in the game progress main processing.

During the settlement processing possible period, if the credit is 1 or more, the main CPU 41 performs settlement processing upon input of a detection signal from the settlement button 19. Also, during the settlement processing possible period, even if the credit is 0, if the number of bets is 1 or more, the main CPU 41 performs settlement processing upon input of a detection signal from the settlement button 19. However, the case where the number of bets is 1 or more is premised on the premise that the number of bets is not the number of bets set by granting a replay. Note that even if a replay is granted and the number of bets is 1 or more, if the credit is 1 or more, the main CPU 41 performs settlement processing upon input of a detection signal from the settlement button 19.

In the settlement process, if the credit stored in the main RWM 43 is 1 or more, the main CPU 41 controls the hopper unit HU to pay out (settle) the number of medals stored as the credit. In addition, in the settlement process, if the replay operation is not in progress and the number of bets is 1 or more, the main CPU 41 controls the hopper unit HU to pay out (settle) the number of medals set as the number of bets. However, in the replay operation, the main CPU 41 does not control the hopper unit HU to pay out the number of medals set as the number of bets, and controls the hopper unit HU to pay out only the number of medals stored as the credits if the credits are 1 or more. In this way, the number of medals set as the number of bets is not settled during the replay operation. In addition, when performing the settlement process, the main CPU 41 stores control information (hereinafter referred to as a settlement command) that can specify that the settlement process is to be performed in the output buffer.

When the main CPU 41 receives a detection signal from the door open sensor KS, the main CPU 41 stores in the output buffer control information (hereinafter referred to as a door open command) that can identify that the front door 12 is open. The door open command continues to be output to the sub-board 50 when the front door 12 is open, and ends when the front door 12 is closed. When the main CPU 41 receives a detection signal from the lock operation sensor SS, the main CPU 41 stores in the output buffer control information (hereinafter referred to as a lock operation command) that can identify that the locking unit SJ has been operated counterclockwise.

Next, the process performed by the secondary CPU 51 after a state in which a game can be played will be described.
When the sub-CPU 51 inputs a game status command, it updates the game status information stored in the sub-RWM 53. At this time, the sub-CPU 51 updates the game status information to one that indicates a game status that can be specified from the game status command. Also, when the sub-CPU 51 inputs a presentation status command, it updates the presentation status information stored in the sub-RWM 53. At this time, the sub-CPU 51 updates the presentation status information to one that indicates a presentation status that can be specified from the presentation status command.

When the sub-CPU 51 inputs a multiplication number setting command, it controls to a presentation state that can be specified from the presentation state information. Incidentally, after the replay role is won, when the sub-CPU 51 inputs a variable game start command, it controls to a presentation state that can be specified from the presentation state information. Specifically, when the type of presentation state that can be specified from the presentation state information is changed, the sub-CPU 51 controls to the presentation state after the change. On the other hand, when the type of presentation state that can be specified from the presentation state information is not changed, the sub-CPU 51 continues to control to the presentation state being controlled. For example, when the presentation state that can be specified from the presentation state information is changed from a presentation state other than the normal presentation state to the normal presentation state, the sub-CPU 51 controls to the normal presentation state by controlling the presentation display device 15 to switch to the background image in the normal presentation state and display it. Furthermore, the sub-CPU 51 controls to the normal presentation state by controlling the decorative lamp 13 to emit light in the light color in the normal presentation state and controlling the speaker 14 to output background music in the normal presentation state.

When the instruction information command is input, the sub-CPU 51 performs push order navigation performance processing to execute a navigation performance that suggests or notifies the push order. The sub-CPU 51 performs push order navigation performance processing based on the winning number that can be specified from the winning information command and the instruction information that can be specified from the instruction information command. In the push order navigation performance processing, the sub-CPU 51 controls the performance display device 15 so that a navigation performance based on the instruction information that can be specified from the instruction information command is executed. For example, when executing a navigation performance that suggests or notifies the fourth push order, the sub-CPU 51 executes a navigation performance in which a navigation image NG containing "3", a navigation image NG containing "1", and a navigation image NG containing "2" are displayed from the left in the area above the stop buttons 21 to 23 on the performance display device 15. The sub-CPU 51 controls the performance display device 15 so that the navigation performance is executed until all the reels 16a to 16c stop rotating. In the slot machine 10, the reels 16a to 16c rotate after the instruction information command is output, so that the navigation performance is executed while the reels are rotating. That is, in this embodiment, the performance execution means can execute a performance related to the operation of the stop operation means when the reels are spinning. In this way, in the slot machine 10, when the reels 16a to 16c are spinning during the execution of the variable game, a navigation performance is executed in the performance display device 15. That is, in this embodiment, when the reels are spinning during the execution of the variable game, the performance execution means can execute a performance related to the operation of the stop operation means. As described above, in the slot machine 10, when the reels 16a to 16c are spinning during the execution of the variable game, instruction information is displayed in the payout display unit 37, a navigation performance is executed in the performance display device 15, and a performance related to the operation of the stop button can be executed in both the payout display unit 37 and the performance display device 15. That is, in this embodiment, when the reels are spinning during the execution of the variable game, the notification means and the performance execution means can execute a performance related to the operation of the stop operation means.

Incidentally, when the secondary CPU 51 is executing a navigation performance based on instruction information identifiable from the instruction information command, if the stop buttons are operated in a different order from the order suggested or notified in the navigation performance, the secondary CPU 51 ends the navigation performance and stops the execution of the navigation performance. For this reason, in the slot machine 10, for example, when a navigation performance suggesting or notifying the fourth push order is being executed, if the stop buttons 21 and 23 other than the stop button 22 are operated for the first time, the navigation performance ends. Also, in the slot machine 10, for example, when a navigation performance suggesting or notifying the fourth push order is being executed, if the stop button 22 is operated for the first time but the stop button 21 is operated for the second time, the navigation performance ends. Note that in the slot machine 10, even if the execution of the navigation performance in the performance display device 15 is stopped, the display of instruction information in the payout display unit 37 continues.

When the sub-CPU 51 inputs a stagnation start command, it performs a white seven navigation effect process to execute a navigation effect that suggests or notifies the white seven symbol as a target position. In the white seven navigation effect process, the sub-CPU 51 controls the effect display device 15 so that a pattern image ZG including an image imitating a white seven symbol is displayed and a navigation effect that suggests or notifies the white seven symbol as a target position is executed. In addition, when the sub-CPU 51 inputs a stagnation end command, it may perform an add-on effect process to execute an add-on effect that suggests or notifies the number of times added. Specifically, in principle, when an add-on number command is input, the sub-CPU 51 performs an add-on effect process. On the other hand, when an add-on number command is not input, the sub-CPU 51 does not perform an add-on effect process. In the add-on effect process, the sub-CPU 51 specifies the number of times added from the input add-on number command, and controls the effect display device 15 so that an add-on effect that notifies the number of times added is executed. In this embodiment, the add-on effect corresponds to a bonus granting effect that suggests or notifies that a bonus will be granted. In slot machine 10, when the added effect is executed in effect display device 15, reels 16a-16c are stopped beforehand based on the first effect stop pattern, so that a symbol combination in which a white seven symbol is displayed at the center stop position of each reel is displayed, and the added effect is executed. In other words, in slot machine 10, when a specific symbol combination stops while freeze control is being performed, a bonus awarding effect is executed in the effect execution means, and a bonus is awarded.

In this embodiment, the period from when the secondary CPU 51 inputs the stagnation start command to when it inputs the stagnation end command corresponds to the time when freeze control is being performed in the primary CPU 41. Therefore, in the performance display device 15, when the freeze control is being performed and the reel is spinning, a navigation performance is executed that suggests or notifies the white seven symbol as a target pressing position. Since the reel is spinning during at least a portion of the period during which the freeze control is being performed, the navigation performance is executed when the reel is spinning. That is, in this embodiment, the performance execution means is capable of executing an operation performance related to the operation of the stop operation means when the reel is spinning. Specifically, in this embodiment, the performance execution means is capable of executing an operation performance related to the operation of the stop operation means when the freeze control is being performed and the reel is spinning. That is, in the display means, when the freeze control is being performed and the reel is spinning, an operation performance related to the operation of the stop operation means is capable of executing. Thus, in this embodiment, the operation performance executed when the freeze control is being performed suggests or notifies the target pressing position. That is, in this embodiment, the operation presentation executed when freeze control is being performed suggests or suggests at least some of the symbols that would be displayed on the display unit if the reels stopped spinning.

In addition, during the period between inputting the stagnation start command and inputting the stagnation end command, the performance display device 15 executes a navigation performance, while the payout display unit 37 does not display any instruction information. In other words, in the slot machine 10, when freeze control is being performed and the reels are spinning, the performance display device 15 executes a navigation performance, while the payout display unit 37 does not display any instruction information. In other words, in this embodiment, when freeze control is being performed and the reels are spinning, only the performance execution means out of the notification means and the performance execution means can execute a performance related to the operation of the stop operation means.

When an operation command is input, the sub-CPU 51 controls the speaker 14 to output a stop sound. Similarly, when a stagnation operation command is input, the sub-CPU 51 controls the speaker 14 to output a stop sound. In this way, in the slot machine 10, similar to when the reels stop spinning in a variable game, even when the reels stop spinning while freeze control is being performed, a stop sound is output from the speaker 14 in association with the reels stopping spinning. In this way, a stop sound corresponding to a non-specific sound is output from the sound output means in association with the reels stopping spinning.

When the sub-CPU 51 inputs a settlement command, it performs a settlement performance execution process that executes a settlement performance related to the settlement of medals (game media). In the settlement performance execution process, the sub-CPU 51 controls the performance display device 15, for example, so that an image related to a settlement performance indicating that medals are being settled is displayed. The sub-CPU 51 also controls the decorative lamp 13, for example, so that it emits light in a light emission mode related to the settlement performance. The sub-CPU 51 controls the speaker 14 so that a sound related to the settlement performance is output.

When the sub-CPU 51 inputs a door open command, it performs an opening performance process that executes an opening performance that suggests or notifies that the front door 12 is open. In the opening performance process, the sub-CPU 51 controls at least one of the decorative lamps 13, the speaker 14, and the performance display device 15, for example, so that an opening performance that suggests or notifies that the door is open is executed. For example, when an opening performance is executed, a door open image TG is displayed on the performance display device 15. The door open image TG is an image that includes text information such as "Door is open." The opening performance ends when the door open command is no longer input, that is, when the front door 12 is closed.

Next, the control relating to the volume adjustment will be described.
When a detection signal is input from the up button B1 in a situation where the volume can be adjusted, if the volume level identifiable from the volume information has not reached the upper limit (the eighth level of volume in this embodiment), the sub-CPU 51 raises the volume level by one and updates the volume information to identify the volume level after the increase. The volume information is stored in the sub-RWM 53. The volume information is information that identifies the volume set among the levels that can be set as the volume. Furthermore, when a detection signal is input from the down button B2 in a situation where the volume can be adjusted, if the volume level identifiable from the volume information has not reached the lower limit (the first level of volume in this embodiment), the sub-CPU 51 lowers the volume level by one and updates the volume information to identify the volume level after the decrease. Furthermore, when the control signal from the changeover switch SW is switched, the sub-CPU 51 updates the volume information to identify the level identifiable from the switched control signal. The sub-CPU 51 controls the speaker 14 so that sound is output at a volume level identifiable from the volume information. That is, the sound output means can execute a performance of outputting sound based on the adjusted volume.

In this embodiment, the sub-CPU 51 controls the decorative lamp 13, thereby realizing a function as a light emission control means that controls the light emission means. In this embodiment, the sub-CPU 51 controls the speaker 14, thereby realizing a function as a sound control means that controls the sound output means. In this embodiment, the sub-CPU 51 controls the performance display device 15, thereby realizing a function as a display control means that controls the display means. Also, in this embodiment, the sub-CPU 51 controls the performance devices that serve as the performance execution means among the decorative lamp 13, the speaker 14, and the performance display device 15, thereby realizing a function as a performance control means that controls the performance execution means. That is, in this embodiment, the sub-control unit has a function as a performance control means. Also, in this embodiment, the processing unit has a function as a performance control means.

However, if the power supply to the main board 40 and the sub-board 50 is stopped as a result of the power plug PG being disconnected from the external power source while the power switch 61 is still on, the power will not be stable, and overvoltage or the like may occur, which may cause a malfunction. Therefore, in the slot machine 10, it is recommended that the power supply to the main board 40 and the sub-board 50 be stopped by turning the power switch 61 inside the machine from on to off.

In the slot machine 10, if the power plug PG is disconnected from the external power source while the power switch 61 is still on, a power-off warning effect is executed. Executing the power-off warning effect suggests or notifies the user that the power supply has not been stopped in the recommended manner. In this embodiment, executing the power-off warning effect is equivalent to issuing a warning. On the other hand, in the slot machine 10, if the power supply to the main board 40 and the sub-board 50 is stopped by switching the power switch 61 from the on state to the off state, a power-off thank-you effect is executed. Executing the power-off thank-you effect suggests or notifies the user that the power supply has been stopped in the recommended manner.

As shown in FIG. 9(a), in the slot machine 10, when the power plug PG is disconnected from the external power source while the power switch 61 is on, as the power supply is resumed, a power-off warning image 90 is displayed on the performance display device 15, and a power-off warning performance is executed. The power-off warning image 90 is an image including text information such as "Please operate the power switch inside the machine to turn the power OFF." In this embodiment, the power-off warning performance corresponds to a warning regarding the interruption of the power supply. In other words, the execution of the power-off warning performance corresponds to the execution of a warning regarding the interruption of the power supply. In this way, when the power supply is stopped while the power switch 61 is on, the performance display device 15 executes a warning regarding the interruption of the power supply.

Also, as shown in FIG. 9(b), in the slot machine 10, when the power switch 61 is switched from the on state to the off state, a power-off thank-you image 91 is displayed on the performance display device 15 as the power supply is resumed, and a power-off thank-you performance is executed. The power-off thank-you image 91 is an image including text information such as "Thank you for the proper power-off operation." In this embodiment, the power-off thank-you performance corresponds to a special performance. In this way, when the power supply is stopped as a result of the power switch 61 being switched from the on state to the off state, the performance display device 15 executes a power-off thank-you performance.

As described above, in the slot machine 10, when the power supply is stopped as a result of the power switch 61 being switched from the on state to the off state, the power cut thank-you performance is executed by the performance display device 15. On the other hand, in the slot machine 10, when the power supply is stopped with the power switch 61 remaining on, the power cut warning performance is executed by the performance display device 15. In other words, in the slot machine 10, when the power supply is stopped as a result of the power switch 61 being switched from the on state to the off state and when the power supply is stopped with the power switch 61 remaining on, the performance content of the performance display device 15 when the power supply is subsequently started is different. In other words, in this embodiment, when the power supply is stopped as a result of the power switch being switched from the on state to the off state and when the power supply is stopped with the power switch remaining on, the performance content of the performance execution means when the power supply is subsequently started is different.

Incidentally, the power switch 61 can be operated by opening the front door 12. Therefore, if the power supply is stopped by opening the front door 12 and switching the power switch 61 from on to off, this means that the power supply is stopped when the power switch 61 is switched from on to off. In other words, if the power supply is stopped by opening the door member and switching the power switch from on to off, this means that the power supply is stopped when the power switch is switched from on to off. On the other hand, if the power supply is stopped without opening the front door 12 and the power switch 61 is still on, this means that the power supply is stopped with the power switch 61 still on. In other words, if the power supply is stopped without opening the door member and the power switch is still on, this means that the power supply is stopped with the power switch still on.

In the slot machine 10, the power failure warning performance does not end even if the front door 12 is switched from an open state to a closed state. The power failure warning performance ends when a predetermined release condition is met. In this embodiment, the predetermined release condition is met when the locking unit SJ is operated counterclockwise. That is, when the power failure warning performance is executed, the power failure warning performance ends when the locking unit SJ is operated counterclockwise. In this manner, in this embodiment, the warning regarding the stop of the power supply does not end even if the door member is switched from an open state to a closed state, but ends when a predetermined release condition is met. Similarly, in the slot machine 10, the power failure thank-you performance does not end even if the front door 12 is switched from an open state to a closed state. The power failure thank-you performance ends when a predetermined release condition is met, like the power failure warning performance. That is, when the power-off thank-you performance is executed, the power-off thank-you performance ends when the locking unit SJ is operated counterclockwise. Thus, in this embodiment, the special performance does not end even if the door member switches from an open state to a closed state, but ends when a specified release condition is met.

In addition, if power supply to the main board 40 and the sub-board 50 begins when the power plug PG is connected to an external power source while the power switch 61 is on, the power may become unstable, resulting in overvoltage and other problems that may cause malfunctions. Therefore, in the slot machine 10, it is recommended that power supply to the main board 40 and the sub-board 50 be started by switching the power switch 61 inside the machine from off to on.

In the slot machine 10, if the power plug PG is connected to an external power source while the power switch 61 is in the on state, a power restoration warning effect is executed. Executing the power restoration warning effect suggests or notifies that power supply has started in the recommended manner. In this embodiment, executing the power restoration warning effect corresponds to issuing a warning. On the other hand, in the slot machine 10, if power supply to the main board 40 and the sub-board 50 is started by switching the power switch 61 from the off state to the on state while the power plug PG is connected to an external power source, a power restoration thank you effect is executed. Executing the power restoration thank you effect suggests or notifies that power supply has started in the recommended manner.

As shown in FIG. 10(a), in the slot machine 10, when the power plug PG is connected to an external power source with the power switch 61 remaining on and power supply is resumed, a power restoration warning image 95 is displayed on the display device 15 and a power restoration warning display is executed. The power restoration warning image 95 is an image including text information such as "Please operate the power switch inside the machine to turn the power ON." In this embodiment, the power restoration warning display corresponds to a warning regarding the start of power supply. In other words, the execution of the power restoration warning display corresponds to the execution of a warning regarding the start of power supply. In this way, when power supply is started with the power switch 61 remaining on, the display device 15 executes a warning regarding the start of power supply.

Also, as shown in FIG. 10(b), in the slot machine 10, when the power switch 61 is switched from an off state to an on state and power supply is resumed, a power restoration thank you image 96 is displayed on the performance display device 15, and a power restoration thank you performance is executed. The power restoration thank you image 96 is an image including text information such as "Thank you for turning the power on properly." In this embodiment, the power restoration thank you performance corresponds to the specific performance. In this way, when power supply is resumed as a result of the power switch 61 being switched from an off state to an on state, the power restoration thank you performance is executed on the performance display device 15.

As described above, in the slot machine 10, when power supply is started in response to the power switch 61 being switched from an off state to an on state, the power restoration thank-you effect is executed by the effect display device 15. On the other hand, in the slot machine 10, when power supply is started with the power switch 61 remaining on, the power restoration warning effect is executed by the effect display device 15. In other words, in the slot machine 10, when power supply is started in response to the power switch 61 being switched from an off state to an on state and when power supply is started with the power switch 61 remaining on, the effect content of the effect display device 15 when power supply is started is different. In other words, in this embodiment, when power supply is started in response to the power switch being switched from an off state to an on state and when power supply is started with the power switch remaining on, the effect content of the effect execution means when power supply is started is different.

Incidentally, the power switch 61 can be operated by opening the front door 12. Therefore, if the power supply is started by opening the front door 12 and switching the power switch 61 from the off state to the on state, this is a case where the power supply is started when the power switch 61 is switched from the off state to the on state. In other words, if the power supply is started when the door member is opened and the power switch is switched from the off state to the on state, this is a case where the power supply is started when the power switch is switched from the off state to the on state. On the other hand, if the power supply is started after the front door 12 is opened and the power switch 61 is switched from the off state to the on state, and then the front door 12 is closed, this is a case where the power supply is started with the power switch 61 in the on state. In other words, if the power supply is started after the door member is opened and the power switch is switched from the off state to the on state, and then the door member is closed, this is a case where the power supply is started with the power switch in the on state.

In the slot machine 10, the power restoration warning effect ends when the front door 12 switches from an open state to a closed state. That is, in this embodiment, the warning regarding the start of power supply ends when the door member switches from an open state to a closed state. Similarly, in the slot machine 10, the power restoration thank you effect ends when the front door 12 switches from an open state to a closed state. That is, in this embodiment, the specific effect ends when the door member switches from an open state to a closed state.

Here, we will explain the control related to the execution of the power outage warning effect, the power outage thank you effect, the power restoration warning effect, and the power restoration thank you effect. Note that in the slot machine 10, when power is being supplied from the power supply circuit 62 to the monitoring unit 72, this corresponds to the time when power is being supplied to the main board 40 and the sub-board 50. Also, in the slot machine 10, when power is being supplied from the conversion circuit 71 to the monitoring unit 72, this corresponds to the time when the power plug PG is connected to an external power source.

In the following description, the first situation is when power is supplied from the conversion circuit 71 to the monitoring CPU 81 and power is supplied from the power supply circuit 62 to the monitoring CPU 81. The second situation is when power is supplied from the conversion circuit 71 to the monitoring CPU 81 and power is not supplied from the power supply circuit 62 to the monitoring CPU 81. The third situation is when power is not supplied from the conversion circuit 71 to the monitoring CPU 81 and power is not supplied from the power supply circuit 62 to the monitoring CPU 81 and power is supplied from the auxiliary power supply 73 to the monitoring CPU 81. When power is supplied from the auxiliary power supply 73 to the monitoring CPU 81, power is not supplied from the conversion circuit 71 to the monitoring CPU 81. Incidentally, the first situation corresponds to, for example, a situation in which the power plug PG is connected to an external power supply and the power switch 61 is in an on state. The second situation corresponds to, for example, a situation in which the power plug PG is connected to an external power supply and the power switch 61 is in an off state. The third situation corresponds, for example, to a situation in which the power plug PG is not connected to an external power source.

The monitoring CPU 81 monitors whether or not power is being supplied from the conversion circuit 71, the power supply circuit 62, and the auxiliary power supply 73, and determines which of the first to third situations it is in. Specifically, when power is being supplied from the conversion circuit 71 and also from the power supply circuit 62, the monitoring CPU 81 determines that it is in the first situation. When power is being supplied from the conversion circuit 71 and also from the power supply circuit 62, the monitoring CPU 81 determines that it is in the second situation. When power is being supplied from both the conversion circuit 71 and the power supply circuit 62 and also from the auxiliary power supply 73, the monitoring CPU 81 determines that it is in the third situation.

When the monitoring CPU 81 determines that the first situation has been switched to the second situation, it determines that the power supply has been stopped when the power switch 61 has been switched from the on state to the off state. At this time, the monitoring CPU 81 stores in the monitoring RWM 83 information (hereinafter referred to as the first power-off information) that can identify that the power supply has been stopped when the power switch 61 has been switched from the on state to the off state. The monitoring RWM 83 stores and holds the first power-off information until the power supply is started and the first situation is resumed. Note that the switch from the first situation to the second situation corresponds to the stop of the power supply to the main board 40 and the sub-board 50 when the power switch 61 has been switched off in a situation in which the power switch 61 has been identified as being on. That is, if the monitoring unit determines that the power supply to the processing unit was stopped when the power switch was switched to the OFF state while the power switch was in the ON state, the monitoring unit determines that the power supply was stopped when the power switch was switched from the ON state to the OFF state, and stores and holds the result of the determination.

When the monitoring CPU 81 determines that the first situation has been switched to the third situation, it determines that the power supply has been stopped with the power switch 61 remaining on. At this time, the monitoring CPU 81 stores in the monitoring RWM 83 information that can identify that the power supply has been stopped with the power switch 61 remaining on (hereinafter referred to as second power-off information). The monitoring RWM 83 stores and holds the second power-off information until the power supply is started and the first situation is resumed. Note that the switch from the first situation to the third situation corresponds to the switch from a situation in which the power switch 61 is on and power is being supplied to the main board 40 and the sub-board 50 to a situation in which the power switch 61 is on and power supply to the main board 40 and the sub-board 50 is stopped. That is, when the monitoring unit determines that the state has changed from one in which the power switch is on and power is being supplied to the processing unit to one in which the power switch is on and power supply to the processing unit is stopped, it determines that the power supply has been stopped with the power switch still on, and stores and retains the result of this determination.

When the monitoring CPU 81 determines that the second situation has been switched to the first situation, it determines that the power supply has started when the power switch 61 has been switched from the off state to the on state. Then, the monitoring CPU 81 outputs control information (hereinafter, referred to as the first power recovery command) to the sub-CPU 51 that can determine that the power supply has started when the power switch 61 has been switched from the off state to the on state. Note that the switch from the second situation to the first situation corresponds to the start of the power supply to the main board 40 and the sub-board 50 when the power switch 61 has been turned on in a situation where the power switch 61 has been determined to be in the off state. In other words, when the monitoring unit determines that the power supply to the processing unit has been started when the power switch has been turned on in a situation where the power switch has been determined to be in the off state, it determines that the power supply has started when the power switch has been turned on from the off state.

When the monitoring CPU 81 determines that the third situation has been switched to the first situation, it determines that power supply has been started with the power switch 61 remaining on. Then, the monitoring CPU 81 outputs control information (hereinafter referred to as a second power recovery command) to the sub-CPU 51 that can determine that power supply has been started with the power switch 61 remaining on. Note that when the third situation is switched to the first situation, it corresponds to a situation in which the power switch 61 is on and power supply to the main board 40 and the sub-board 50 has not been started, but has been switched to a situation in which the power switch 61 is on and power supply to the main board 40 and the sub-board 50 has been started. In other words, when the monitoring unit determines that the situation has been switched from a situation in which the power switch is on and power supply to the processing unit has not been started, but has been switched to a situation in which the power switch is on and power supply to the processing unit has been started, it determines that power supply has been started with the power switch remaining on.

The monitoring CPU 81 outputs control information to the secondary CPU 51 that can specify how the power supply was stopped in both cases where the second situation was switched to the first situation and where the third situation was switched to the first situation. Specifically, when the first power-off information is stored in the monitoring RWM 83, the monitoring CPU 81 outputs control information (hereinafter referred to as the first power-off command) to the secondary CPU 51 that can specify that the power supply was stopped when the power switch 61 was switched from the on state to the off state. After outputting the first power-off command, the monitoring CPU 81 erases the first power-off information stored in the monitoring RWM 83. On the other hand, when the second power-off information is stored in the monitoring RWM 83, the monitoring CPU 81 outputs control information (hereinafter referred to as the second power-off command) to the secondary CPU 51 that can specify that the power supply was stopped with the power switch 61 remaining on. After outputting the second power-off command, the monitoring CPU 81 erases the second power-off information stored in the monitoring RWM 83.

When the sub-CPU 51 receives a first power-off command, it controls the performance display device 15 so that a power-off thank-you performance is executed. On the other hand, when the sub-CPU 51 receives a second power-off command, it controls the performance display device 15 so that a power-off warning performance is executed. In this way, when power supply is started, the sub-CPU 51 controls the performance display device 15 based on the result of the determination in the monitoring unit 72. In other words, when power supply is started, the performance control means controls the performance execution means based on the result of the determination in the monitoring unit.

When the sub-CPU 51 receives a first power restoration command, it controls the performance display device 15 so that a power restoration thank-you performance is executed. On the other hand, when the sub-CPU 51 receives a second power restoration command, it controls the performance display device 15 so that a power restoration warning performance is executed. In this way, the sub-CPU 51 controls the performance display device 15 based on the result of the determination in the monitoring unit 72. In other words, the performance control means controls the performance execution means based on the result of the determination in the monitoring unit.

Here, based on Figures 11(a) and 11(b), we will explain the difference in the display content of the performance display device 15 depending on how the power supply is stopped, and the difference in the display content of the performance display device 15 depending on how the power supply is started.

As shown in FIG. 11(a), when the power supply is resumed after the power plug PG is disconnected from the external power source while the power switch 61 is on, the power failure warning image 90 is displayed on the performance display device 15, and the power failure warning performance is executed. This power failure warning performance is ended by operating the locking unit SJ counterclockwise. On the other hand, as shown in FIG. 11(b), when the power supply is resumed after the power switch 61 is switched from the on state to the off state to stop the power supply, the power failure thank-you image 91 is displayed on the performance display device 15, and the power failure thank-you performance is executed. This power failure thank-you performance is ended by opening the front door 12 and then closing the front door 12, even if the front door 12 is closed. Also, if the front door 12 is open when the power failure thank-you performance is executed, the power failure thank-you performance is ended by closing the front door 12. As described above, in the slot machine 10, if the power supply is stopped when the power switch 61 is switched from the on state to the off state, the performance content (display content) of the performance display device 15 when the power supply is then restarted will be different from if the power supply is stopped while the power switch 61 remains on.

As shown in FIG. 11(a), when the power supply is started by connecting the power plug PG to an external power source while the power switch 61 is in the on state, the power recovery warning image 95 is displayed on the performance display device 15, and the power recovery warning performance is executed. This power recovery warning performance is ended by operating the locking unit SJ in a counterclockwise direction. On the other hand, as shown in FIG. 11(b), when the power supply is started by switching the power switch 61 from the off state to the on state, the power recovery thank you image 96 is displayed on the performance display device 15, and the power recovery thank you performance is executed. This power recovery thank you performance ends by opening the front door 12 and then closing the front door 12, even when the front door 12 is closed. However, since the power switch 61 cannot be operated unless the front door 12 is opened, when the power supply is started by switching the power switch 61 from the off state to the on state, it is assumed that the power recovery thank you performance will be executed when the front door 12 is open. In this case, the power recovery thank you performance ends by closing the front door 12. As described above, in the slot machine 10, when power supply is started as a result of the power switch 61 being switched from an off state to an on state, the presentation content (display content) of the presentation display device 15 when power supply is started is different from when power supply is started while the power switch 61 remains on.

Incidentally, as shown in FIG. 11(a), when power supply is started by connecting the power plug PG to an external power source, it is assumed that the power switch 61 is not operated and therefore the front door 12 is not opened, and therefore the door open image TG is not displayed on the performance display device 15 and the opening performance is not executed. On the other hand, as shown in FIG. 11(b), when power supply is started by switching the power switch 61 from the off state to the on state, it is assumed that the front door 12 is opened to operate the power switch 61, and therefore the door open image TG is displayed on the performance display device 15 and the opening performance is executed. For this reason, in the slot machine 10, whether or not the opening performance is executed differs between when power supply is started triggered by switching the power switch 61 from the off state to the on state and when power supply is started with the power switch 61 remaining on, and the performance content (display content) of the performance display device 15 when power supply is started differs.

Next, we will explain the case where power supply is stopped and then resumed while a variable game is being played, and the case where power supply is stopped and then resumed while freeze control is being performed. In the following explanation, the case where power supply is stopped and then started, or the case where power supply is stopped and then resumed, refers to the case where the set value switch 45 is not operated when power supply starts, and the main backup process and sub-backup process are performed normally.

If the power supply to the slot machine 10 is stopped while the variable game is being executed, the slot machine 10 will return to the variable game being executed. Also, if the power supply to the slot machine 10 is stopped while the freeze control is being executed and then the power supply is resumed, the slot machine 10 will return to the freeze control.

A case where the power supply is stopped during the execution of a variable game corresponds to a case where the power supply is stopped when any of steps S115 to S119 is being processed in the game progress main processing (shown in FIG. 7). A case where the power supply is returned during the execution of a variable game corresponds to a case where the power supply is resumed from any of steps S115 to S119 in the game progress main processing. For example, if the power supply is stopped after the speed at which the reels rotate in the variable game has already reached a constant speed, when the power supply is resumed, the game will be resumed from any of steps S116 to S119. Even if the game is resumed from any of steps S115 to S119, if at least some of the reels are rotating, the game will move to the processing of step S116. Even if the game returns while the game is being processed in step S117, the determination result of step S117 cannot be determined as positive by operating the stop button within the period until the processing of step S117 is completed, and the game will move to the processing of step S116. As a result, if the return occurs during the execution of the variable game, unless the determination result of step S116 is positive, the determination result of step S117 will be positive, and the rotation of the reels cannot be stopped. Therefore, in the slot machine 10, if the power supply is stopped and then started while the reels are rotating during the execution of the variable game, the return occurs during the execution of the variable game. And, in the slot machine 10, even if the stop button is operated at a timing before the speed at which the reels rotate reaches a constant speed after the power supply is started, the rotation of the reels cannot be stopped. In other words, if the power supply is stopped and then started while the reels are rotating during the execution of the variable game, the return occurs during the execution of the variable game, and even if the stop operation means is operated at a timing before the speed at which the reels rotate reaches a constant speed after the power supply is started, the rotation of the reels cannot be stopped.

As shown in FIG. 12(a), when a variable game is being played and the reels are spinning at a constant speed, the power supply is stopped at timing t11, causing the reels to stop spinning. Thereafter, power supply is started again at timing t12, and the speed at which the reels spin (shown as the reel spinning speed in FIG. 12(a)) reaches the constant speed over the following timing t13. In this case, during the period from timing t12 when the power supply is started to timing t13 when the reels reach the constant speed, the reels cannot be stopped from spinning even by operating the stop button (shown as "stop operation not possible" in FIG. 12(a)). On the other hand, after timing t13 when the reels reach the constant speed, the reels can be stopped from spinning by operating the stop button (shown as "stop operation possible" in FIG. 12(a)).

When the power supply is stopped while the reels are rotating during the freeze control, this corresponds to the case where the power supply is stopped during any of steps S206 to S210 in the stagnation effect processing (shown in FIG. 8). A return to the freeze control corresponds to a resumption from any of steps S206 to S210 in the stagnation effect processing. For example, when the power supply is stopped after the speed at which the reels rotate has already reached a constant speed during the freeze control, when the power supply is resumed, the processing is resumed from any of steps S208 to S210. When the processing is resumed from any of steps S208 to S209, if at least some of the reels are rotating, the processing proceeds to step S208, and the reels can be stopped by operating the stop button. As a result, when the freeze control is returned, even if the speed at which the reels rotate has not reached a constant speed, the judgment result of step S208 becomes positive, and the reels can be stopped from rotating. Therefore, in the slot machine 10, if the power supply is stopped while the reels are spinning during freeze control and then power supply is started again, the freeze control is restored. In addition, in the slot machine 10, it is possible to stop the rotation of the reels by operating the stop button at a timing before the speed at which the reels spin reaches a constant speed after the power supply is started. In other words, if the power supply is stopped while the reels are spinning during freeze control and then power supply is restarted, the freeze control is restored, and it is possible to stop the rotation of the reels by operating the stop operation means at a timing before the speed at which the reels spin reaches a constant speed after the power supply is started.

As shown in FIG. 12(b), when freeze control is being performed and the reels are rotating at a constant speed, the power supply is stopped at timing t21, causing the reels to stop rotating. Thereafter, power supply is started again at timing t22, and the speed at which the reels rotate (shown as the reel rotation speed in FIG. 12(b)) reaches a constant speed by the time of the subsequent timing t23. In this case, after timing t22 when power supply is started, the reels can be stopped from rotating by operating the stop button, even before the reels reach a constant speed (shown as being operable to stop in FIG. 12(b)).

In the slot machine 10, a navigation effect may be executed that suggests or notifies the user of the order in which to press the stop buttons while the variable game is being executed. In the slot machine 10, when the reels are spinning during the execution of the variable game and the navigation effect is being executed by the effect display device 15, if the power supply is stopped and then resumed, the game returns to being executed during the variable game and the reels spin. Furthermore, the effect display device 15 executes a navigation effect. That is, when the reels are spinning during the execution of the variable game and the operation effect is being executed by the effect execution means, if the power supply is stopped and then resumed, the game returns to being executed during the variable game and the reels spin, and the operation effect is executed again by the effect execution means.

In addition, in the slot machine 10, when the navigation effect is being executed by the effect display device 15 during the execution of the variation game, instruction information is displayed on the payout display unit 37. In this way, if the power supply is stopped and then resumed while the reels are spinning during the execution of the variation game and the instruction information is being displayed on the payout display unit 37, the variation game returns to being executed, the reels spin, and the instruction information is displayed. In other words, if the power supply is stopped and then resumed while the reels are spinning during the execution of the variation game and the effect related to the operation of the stop operation means is being executed by the notification means, the variation game returns to being executed, the reels spin, and the effect related to the operation of the stop operation means is executed again by the notification means. As described above, when the power supply is stopped while the reels are spinning during the execution of the variable game, and the effects related to the operation of the stop operation means are being executed by both the notification means and the effect execution means, if the power supply is then resumed, the variable game returns to being executed, the reels spin, and the effects related to the operation of the stop operation means are executed again by both the notification means and the effect execution means.

However, in the slot machine 10, when a navigation effect is being executed during the execution of a variable game, if the stop buttons are pressed in a different order from the order suggested or notified in the navigation effect, the navigation effect ends midway. In addition, in the slot machine 10, if the reels are spinning during the execution of a variable game, and the power supply is stopped after the execution of the navigation effect in the effect display device 15 is completed, and then the power supply is resumed, the game returns to being executed during the variable game and the reels spin, but the navigation effect is not executed in the effect display device 15. In other words, if the reels are spinning during the execution of a variable game, and the power supply is stopped after the execution of the operation effect in the effect execution means is completed, and then the power supply is resumed, the game returns to being executed during the variable game and the reels spin, but the operation effect is not executed again in the effect execution means.

Incidentally, in the slot machine 10, even if the navigation effect in the effect display device 15 ends because the stop buttons are pressed in a different order from the order suggested or notified in the navigation effect, the display of the instruction information in the payout display unit 37 continues. In the slot machine 10, if the navigation effect ends midway and the display of the instruction information continues and the reels are spinning, if the power supply is stopped and then resumed, the game returns to being played during the variable game, the reels spin, and the instruction information is displayed. In other words, if the reels are spinning during the variable game, and the power supply is stopped at a timing after the execution of the effect related to the operation of the stop operation means in the effect execution means has ended, the game returns to being played during the variable game, the reels spin, and the effect related to the operation of the stop operation means is executed again in the notification means. As described above, if the reels are spinning during the execution of the variable game, and the power supply is stopped after the performance execution means has finished executing the performance related to the operation of the stop operation means, and then the power supply is resumed, the variable game returns to being executed, the reels spin, and the notification means executes the performance related to the operation of the stop operation means again, but the performance execution means does not execute the performance related to the operation of the stop operation means again.

In addition, in the slot machine 10, when the freeze control is being performed, a navigation effect is executed that suggests or notifies the player of the white seven symbol as the target position. In the slot machine 10, when the freeze control is being performed and the reels are spinning, and when the power supply is stopped and then resumed while the navigation effect is being executed in the effect display device 15, the freeze control is restored and the reels spin, but the navigation effect is not executed. In this way, when the freeze control is being performed and the reels are spinning, and when the power supply is stopped and then resumed while the operation effect is being executed in the effect execution means, the operation effect is not executed again in the effect execution means. In other words, when the freeze control is being performed and the reels are spinning, and when the power supply is stopped and then resumed while the operation effect is being executed in the effect execution means, the freeze control is restored and the reels spin, but the operation effect is not executed again in the effect execution means. In other words, if the reels are spinning while freeze control is being performed, and the performance related to the operation of the stop operation means is being performed by the performance execution means, and then the power supply is stopped and then resumed, freeze control is restored and the reels spin, but the performance related to the operation of the stop operation means is not executed again by the performance execution means.

However, as shown in FIG. 13, when the power supply is resumed, the navigation effect is not executed, but the effect display device 15 executes a stop promotion effect that prompts the player to stop the reel rotation. The stop promotion effect can also be said to be an effect that prompts the player to operate the stop button. As shown in FIG. 13, when the stop promotion effect is executed, a stop promotion image TS is displayed on the effect display device 15. In this embodiment, the stop promotion image TS is an image that includes text information such as "Please stop the reels." The stop promotion effect continues until the freeze control ends, that is, until the stagnation end command is input.

In this way, in the slot machine 10, if the power supply is stopped while the reels are spinning and the navigation performance is being executed by the performance display device 15 and then the power supply is resumed, the navigation performance is not executed but the stop promotion performance is executed. In other words, if the power supply is stopped while the reels are spinning and the operation performance is being executed by the performance execution means and then the power supply is resumed, the operation performance is not executed again by the performance execution means after the power supply is resumed but a stop promotion performance is executed that encourages the user to stop spinning the reels.

Incidentally, when freeze control is being performed and power supply is not stopped, if a white seven symbol is displayed at the middle stop position of each of the reels 16a to 16c and a specific symbol combination is stopped, an additional effect is executed in the effect display device 15. Furthermore, an additional effect is executed and a bonus is awarded. In other words, when freeze control is being performed and a specific symbol combination is stopped without power supply being stopped while the reels are spinning, a bonus awarding effect is executed in the effect execution means to suggest or notify that a bonus will be awarded, and the bonus is awarded.

On the other hand, if the power supply is stopped while the reels are spinning during freeze control, and then the power supply is resumed and a specific symbol combination is stopped by displaying a white seven symbol at the center stop position of each of the reels 16a to 16c, the performance display device 15 does not execute the additional performance. However, in this case, the additional performance is not executed, but the additional performance is executed and the bonus is awarded. In particular, in the slot machine 10, the additional performance is executed internally in the additional lottery process within the advantageous lottery process prior to the stagnation performance process in which the freeze control is executed, so that the bonus is awarded even if the additional performance is not executed. As described above, if the power supply is stopped while the reels are spinning during freeze control, and then the power supply is resumed and a specific symbol combination is stopped, the bonus is awarded while the bonus is not executed in the performance execution means.

Here, we will explain the control related to the navigation presentation when the power supply is stopped while a variable game is being played, and when the power supply is stopped while freeze control is being performed.

When returning during the execution of a variable game as a result of the start of power supply, the main CPU 41 determines whether instruction information was being displayed when the power supply was stopped. If instruction information was being displayed when the power supply was stopped, the main CPU 41 controls the payout display unit 37 so that the instruction information that was being displayed when the power supply was stopped is displayed. Note that if instruction information was not being displayed when the power supply was stopped, the main CPU 41 does not display instruction information on the payout display unit 37 as a result of returning during the execution of a variable game.

In addition, when returning during the execution of a variable game as a result of the start of power supply, the secondary CPU 51 determines whether a navigation performance was being executed when the power supply was stopped. If a navigation performance was being executed when the power supply was stopped, the secondary CPU 51 controls the performance display device 15 so that the navigation performance that was being executed when the power supply was stopped is executed again. Note that, if a navigation performance was not being executed when the power supply was stopped, the secondary CPU 51 does not execute a navigation performance when returning during the execution of a variable game.

When freeze control is restored as a result of the power supply being started, the sub-CPU 51 controls the effect display device 15 so that a stop promotion effect is executed. At this time, the sub-CPU 51 does not execute the navigation effect that suggests or notifies the player of the white seven symbol as a target position, which was executed when the power supply was stopped, as a result of the restoration to freeze control.

Next, based on Figures 14(a) and 14(b), an example of the display content of the performance display device 15 when power supply is stopped while freeze control is being performed will be described.
As shown in FIG. 14(a), when the freeze control is being performed and the reels are spinning, the performance display device 15 executes a navigation effect that suggests or notifies the player of the white seven symbol as the target position. At this time, the performance display device 15 does not execute a stop promotion effect. Then, as shown in FIG. 14(b), when the power supply is stopped while the freeze control is being performed and the reels are spinning, if the power supply is resumed after the power supply is stopped, the performance display device 15 does not execute a navigation effect that suggests or notifies the player of the white seven symbol as the target position, but executes a stop promotion effect. Note that, even if the rotation of the reels stops during the freeze control after the return, and the white seven symbol is stopped and displayed at each of the middle stop positions of the reels 16a to 16c, and a specific symbol combination stops, the performance display device 15 does not execute an additional performance.

In this way, when freeze control is being performed and the reels are spinning and the navigation performance is being executed in the performance display device 15, if the power supply is stopped and then resumed, the navigation performance is executed in the performance display device 15 before the power supply is stopped. On the other hand, when freeze control is being performed and the reels are spinning and the navigation performance is being executed in the performance display device 15, if the power supply is stopped and then resumed, the navigation performance is not executed in the performance display device 15 after the power supply is resumed, but the stop promotion performance is executed. In other words, when freeze control is being performed and the reels are spinning and the operation performance is being executed in the performance execution means, if the power supply is stopped and then resumed, the operation performance is executed in the performance execution means before the power supply is stopped, but the operation performance is not executed again in the performance execution means after the power supply is resumed, but the stop promotion performance that encourages the reels to stop spinning is executed.

Incidentally, if the reels are spinning while freeze control is being performed and the stop promotion effect is being executed in the effect display device 15, and then the power supply is stopped and then resumed, the stop promotion effect will be executed again.

In addition, in the slot machine 10, background music is output from the speaker 14 during the execution of the variable game. Furthermore, in the slot machine 10, when the rotation of the reels stops during the variable game, a stop sound is output from the speaker 14 in association with the stop. However, in the slot machine 10, if the power supply is stopped during the execution of the variable game, the background music is not output from the speaker 14 after the power supply is resumed. In this case, in the slot machine 10, background music is output in association with the operation of the start lever 20 to start the next variable game. On the other hand, in the slot machine 10, even if the power supply is stopped during the execution of the variable game, when the rotation of the reels stops during the variable game after the power supply is resumed, a stop sound is output from the speaker 14 in association with the stop. In this way, in the slot machine 10, if the power supply is not stopped during the execution of the variable game, both the background music and the stop sound are output from the speaker 14. That is, in this embodiment, if the power supply is not stopped during the execution of the variable game, both the specific sound and the non-specific sound are output from the sound output means. On the other hand, in the slot machine 10, if the power supply is stopped during the execution of the variable game, after the power supply is resumed, the background music is not output from the speaker 14, but the stop sound is output from the speaker 14. That is, in this embodiment, if the power supply is stopped during the execution of the variable game, after the power supply is resumed, the specific sound is not output from the sound output means, but the non-specific sound is output from the sound output means.

In addition, in the slot machine 10, background music is output from the speaker 14 when the freeze control is being performed. Furthermore, in the slot machine 10, when the rotation of the reels stops while the freeze control is being performed, a stop sound is output from the speaker 14 in association with the stop. However, in the slot machine 10, if the power supply is stopped while the freeze control is being performed, the background music is not output from the speaker 14 after the power supply is resumed. In this case, in the slot machine 10, the background music is output in association with the operation of the start lever 20 to start the next variable game of the variable game that is started after the freeze control is ended. Furthermore, in the slot machine 10, if the power supply is stopped while the freeze control is being performed, the freeze control is restored after the power supply is resumed, but even if the rotation of the reels stops during the freeze control, the stop sound is not output from the speaker 14. In this way, in the slot machine 10, if the power supply is not stopped while the freeze control is being performed, both the background music and the stop sound are output from the speaker 14. That is, in this embodiment, if the power supply is not stopped while the freeze control is being performed, both the specific sound and the non-specific sound are output from the sound output means. On the other hand, in the slot machine 10, if the power supply is stopped while the freeze control is being performed, after the power supply is resumed, the background music is not output from the speaker 14 while the freeze control is being performed while the freeze control is being restored. Similarly, in the slot machine 10, if the power supply is stopped while the freeze control is being performed, after the power supply is resumed, the stop sound is not output from the speaker 14 while the freeze control is being performed while the freeze control is being restored. That is, in this embodiment, if the power supply is stopped while the freeze control is being performed and then the power supply is resumed, the specific sound is not output from the sound output means while the freeze control is being performed while the freeze control is being restored. Also, in this embodiment, if the power supply is stopped while the freeze control is being performed and then the power supply is resumed, the non-specific sound is not output from the sound output means while the freeze control is being performed while the freeze control is being restored. However, in the slot machine 10, even if the power supply is stopped while freeze control is being performed and then the power supply is resumed and freeze control is resumed, if the rotation of the reels is stopped in the variable game that is started after the freeze control ends, a stop sound is output from the speaker 14 in association with the stop.

Here, the control relating to the output of the background music and the stop sound when the power supply is resumed will be described.
When returning during execution of the variable game, the secondary CPU 51 does not output background music. Similarly, when returning to freeze control, the secondary CPU 51 does not output background music. When background music is not being output, the secondary CPU 51 controls the speaker 14 to output background music when a variable game start command is input. At this time, the secondary CPU 51 controls the speaker 14 to output background music in a presentation state that can be specified from presentation state information.

Even if control is returned to during the execution of a variable game, the secondary CPU 51 controls the speaker 14 to output a stop sound when an operation command is input. On the other hand, when control is returned to freeze control, the secondary CPU 51 does not output a stop sound even if a stagnation operation command is input. However, if an operation command is input during the execution of a variable game thereafter, the secondary CPU 51 controls the speaker 14 to output a stop sound.

In addition, in the slot machine 10, the situation in which the volume can be adjusted includes the period during which the variable game is being executed. Therefore, in the slot machine 10, in principle, the volume can be adjusted by operating the buttons B1 and B2 during the execution of the variable game. For example, in the slot machine 10, even if the power supply is stopped during the execution of the variable game, if the power supply is resumed after that, it returns during the execution of the variable game, and the volume can be adjusted by operating the buttons B1 and B2. That is, in this embodiment, if the power supply is stopped during the execution of the variable game and then resumed, it returns during the execution of the variable game, and the volume can be adjusted by operating the adjustment operation means. In this way, in the slot machine 10, when the power supply is stopped during the execution of the variable game, the volume can be adjusted by operating the buttons B1 and B2 during the period during which the variable game is being executed before the power supply is stopped. That is, in this embodiment, when the power supply is stopped during the execution of the variable game, the volume can be adjusted by operating the buttons B1 and B2 during the period during which the variable game is being executed before the power supply is stopped. Although details will be described later, in slot machine 10, there are times when the volume cannot be adjusted even when a variable game is being played.

In the slot machine 10, the situation in which the volume can be adjusted may include the period during which the freeze control is being performed. For example, in the slot machine 10, in principle, when the freeze control is being performed, the volume can be adjusted by operating the buttons B1 and B2. However, in the slot machine 10, if the power supply is stopped while the freeze control is being performed and then resumed, the volume cannot be adjusted even if the freeze control is restored and the buttons B1 and B2 are operated for at least a specific period. In other words, in this embodiment, when the power supply is stopped while the freeze control is being performed and then resumed, the volume cannot be adjusted even if the freeze control is restored and the adjustment operation means is operated for at least a specific period. The "specific period" in the slot machine 10 is the period from when the power supply is resumed to when the variable game is ended. In other words, in this embodiment, the specific period includes at least the period from when the power supply is resumed to when the freeze control is ended. In this way, in the slot machine 10, if the power supply is stopped while freeze control is being performed and then resumed, the volume cannot be adjusted even during the execution of the variable game after freeze control is performed. As described above, in the slot machine 10, if the power supply is stopped while freeze control is being performed, the volume can be adjusted before the power supply is stopped, but the volume cannot be adjusted after the power supply is stopped and resumed. In other words, in the slot machine 10, if the power supply is stopped while freeze control is being performed, the volume can be adjusted by operating the buttons B1 and B2 before the power supply is stopped and during the period during which freeze control is being performed. In other words, in this embodiment, if the power supply is stopped while freeze control is being performed, the volume can be adjusted by operating the adjustment operation means before the power supply is stopped and during the period during which freeze control is being performed.

Here, a control for disabling adjustment of the volume when the power supply is resumed will be described.
When freeze control is restored, the secondary CPU 51 does not update the volume information until the variation game ends, even if a detection signal is input from buttons B1 and B2. As a result, if power supply is stopped while freeze control is being performed and then resumed, the volume cannot be adjusted until the variation game ends. Note that when control is restored during the execution of a variation game, the secondary CPU 51 does not set a period during which the volume cannot be adjusted due to the fact that control has been restored during the execution of the variation game.

In addition, in the slot machine 10, when the power supply is stopped and then resumed, the volume is set. Specifically, when the power supply is stopped when the volume is the same as the volume of the stage set by the changeover switch SW, and then the power supply is resumed, the volume continues to be set to the same volume as the volume of the stage set by the changeover switch SW. On the other hand, when the power supply is stopped when the volume is different from the volume of the stage set by the changeover switch SW, and then the power supply is resumed, the volume is set to the stage set by the changeover switch SW, not to the volume when the power supply was stopped. Thus, in this embodiment, when the power supply is stopped when the volume is a specific volume and then the power supply is resumed, the volume continues to be the specific volume. On the other hand, in this embodiment, when the power supply is stopped when the volume is other than the specific volume and then the power supply is resumed, the volume becomes the specific volume, not to a volume other than the specific volume.

Here, the control for setting the volume information when the power supply is resumed will be described.
In the sub-backup process, the secondary CPU 51 judges whether the stage identifiable from the volume information stored in the secondary RWM 53 is the same as the stage set by the changeover switch SW. If the stage identifiable from the volume information stored in the secondary RWM 53 is the same as the stage set by the changeover switch SW, the secondary CPU 51 does not update the volume information. The volume information at this time becomes volume information that can identify the same stage as the stage set by the changeover switch SW. Also, if the stage identifiable from the volume information stored in the secondary RWM 53 is not the same as the stage set by the changeover switch SW, the secondary CPU 51 updates the volume information to volume information that can identify the same stage as the stage set by the changeover switch SW.

Next, with reference to Figures 15(a) to 15(d), an example of whether background music and a stop sound are output from the speaker 14, a situation in which the volume can be adjusted or not, and volume information that is set when power supply starts will be described.

As shown in FIG. 15(a), it is assumed that the stage set by the changeover switch SW is the fourth stage, and the stage of the volume that can be specified from the volume information (indicated as adjusted volume in FIG. 15(a) to FIG. 15(d)) is the fourth stage. In this case, as shown in FIG. 15(b), if the power supply is stopped and then resumed, the volume stage will remain at the fourth stage. In this way, if the power supply is stopped and then resumed when the volume stage that can be specified from the volume information is the same as the stage set by the changeover switch SW, the volume will remain at the fourth stage. On the other hand, as shown in FIG. 15(c), it is assumed that the stage set by the changeover switch SW is the fourth stage, and the stage of the volume that can be specified from the volume information is the third stage. In this case, as shown in FIG. 15(d), if the power supply is stopped and then resumed, the volume stage will not be the third stage that can be specified from the volume information, but will be the fourth stage set by the changeover switch SW.

As shown in FIG. 15(a), the volume can be adjusted during the execution of the variable game. Furthermore, during the execution of the variable game, background sounds are output from the speaker 14. Furthermore, when the stop button corresponding to the rotating reel is operated while the reels are spinning during the execution of the variable game, the reels stop spinning and a stop sound is output from the speaker 14. Furthermore, as shown in FIG. 15(b), when the power supply is stopped during the execution of the variable game and the reels are spinning, if the power supply is resumed, the game returns to being executed during the execution of the variable game. During the execution of the variable game after the return, the volume can be adjusted in the same way as before the power supply was stopped. On the other hand, during the execution of the variable game after the return, background sounds are not output from the speaker 14. However, even during the execution of the variable game after the return, if the stop button corresponding to the spinning reel is operated, the reels stop spinning and a stop sound is output from the speaker 14.

As shown in FIG. 15(c), when freeze control is being performed, the volume can be adjusted. Furthermore, when freeze control is being performed, background sound is output from the speaker 14. Furthermore, when freeze control is being performed and the reels are spinning, if the stop button corresponding to the spinning reel is operated, the reels stop spinning and a stop sound is output from the speaker 14. Furthermore, as shown in FIG. 15(d), when freeze control is being performed and the power supply is stopped while the reels are spinning, if the power supply is resumed, the freeze control is restored. When freeze control after recovery is being performed, the volume cannot be adjusted. Furthermore, when freeze control after recovery is being performed, background sound is not output from the speaker 14. In addition, when freeze control after recovery is being performed, even if the stop button corresponding to the spinning reel is operated to stop the reel spinning, the stop sound is not output from the speaker 14 as the reel stops spinning.

The effects of this embodiment will be described below.
(1) When power supply is started with the power switch 61 in the on state, it can be assumed that, for example, power supply is performed to the main board 40 and the sub-board 50 as the power plug PG is connected to an external power source while the power switch 61 is in the on state. If power supply is performed to the main board 40 and the sub-board 50 as the power plug PG is connected to an external power source while the power switch 61 is in the on state, the power may not be stable, and overvoltage or the like may occur, which may cause a breakdown. For this reason, it is recommended that power supply to the main board 40 and the sub-board 50 be started by switching the power switch 61 from the off state to the on state. Therefore, the performance content of the performance display device 15 when power supply is started is configured to be different between the case where power supply is started when the power switch 61 is switched from the off state to the on state and the case where power supply is started while the power switch 61 is in the on state. This makes it possible to check how the power supply has started from the performance content of the performance display device 15 when the power supply is started, and makes it possible to properly execute the performance so that power supply to the main board 40 and the sub-board 50 is started by switching the power switch 61 from the off state to the on state.

(2) Even when the power switch 61 is in the OFF state and the power plug PG is not connected to an external power source, the monitoring unit 72 receives power from the auxiliary power source 73. Even when the power switch 61 is in the OFF state and the power plug PG is not connected to an external power source, the monitoring unit 72 can monitor the state of the power switch 61 and the state of power supply to the main board 40 and the sub-board 50. As a result, it is easy to accurately determine whether power supply has started when the power switch 61 has switched from the OFF state to the ON state.

(3) When the front door 12 is opened and the power switch 61 is switched from the OFF state to the ON state, and then the front door 12 is closed and power supply is started, the display device 15 executes a power restoration warning effect. By executing such a power restoration warning effect, even if power supply is started with the power switch 61 still in the ON state, it is possible to prevent power supply from being started from the next time onwards, for example, by connecting the power plug PG to an external power source while the power switch 61 is still in the ON state.

Furthermore, the power restoration warning effect ends when the front door 12 switches from an open state to a closed state. In other words, for example, even if you feel it is troublesome to open the front door 12 and switch the power switch 61 to the ON state and start the power supply by connecting the power plug PG to an external power source, you will eventually need to open the front door 12 to end the power restoration warning effect. This makes it possible to prompt the user to start the power supply when the power switch 61 switches from the OFF state to the ON state. In addition, because it is necessary to open the front door 12 to end the power restoration warning effect, the presence of the power switch 61 can also be confirmed when the front door 12 is opened.

(4) When power supply is started by opening the front door 12 and switching the power switch 61 from an off state to an on state, the display device 15 executes a power restoration thank you performance. The power restoration thank you performance ends when the front door 12 switches from an open state to a closed state. Basically, when power supply is started by switching the power switch 61 from an off state to an on state, it can be assumed that the front door 12 is opened in order to operate the power switch 61. Therefore, by closing the front door 12 and ending the power restoration thank you performance, it is possible to encourage the front door 12 to be closed after power supply is started.

In addition, when the power switch 61 is switched from the OFF state to the ON state while the front door 12 is closed, it is possible that fraud is being committed, since it is a situation in which it is desired to switch the power switch from the OFF state to the ON state without opening the front door 12. However, since the power restoration thank you performance ends when the front door 12 is switched from an open state to a closed state, even if the power switch 61 can be switched from the OFF state to the ON state without opening the front door 12, it is still necessary to open the front door 12 in order to end the power restoration thank you performance. This makes it possible to suppress fraud committed by switching the power switch 61 from the OFF state to the ON state while the front door 12 is closed.

(5) When the power supply is stopped with the power switch 61 in the on state, it can be assumed that the power supply to the main board 40 and the sub-board 50 is stopped, for example, when the power plug PG is disconnected from the external power source while the power switch 61 is in the on state. If the power supply to the main board 40 and the sub-board 50 is stopped with the power plug PG being disconnected from the external power source while the power switch 61 is in the on state, the power may become unstable, causing an overvoltage or the like, which may cause a breakdown. For this reason, it is recommended that the power supply to the main board 40 and the sub-board 50 be stopped by switching the power switch 61 from the on state to the off state. Therefore, the performance content of the performance display device 15 when the power supply is started is configured to be different between when the power supply is stopped as a result of the power switch 61 being switched from the on state to the off state and when the power supply is stopped with the power switch 61 in the on state. This makes it possible to check how the power supply was stopped from the performance content of the performance display device 15 when the power supply was started, and by switching the power switch 61 from the on state to the off state, it becomes possible to execute the performance appropriately so that the power supply to the main board 40 and the sub-board 50 is stopped.

(6) Even if the power switch 61 is in the OFF state and the power plug PG is not connected to an external power source, the monitoring unit 72 receives power from the auxiliary power source 73. Even if the power plug PG is not connected to an external power source, the monitoring unit 72 can determine whether the power supply has been stopped when the power switch 61 is switched from the ON state to the OFF state, and can store and retain the result of the determination.

(7) In the event that the power supply is stopped with the power switch 61 remaining on without opening the front door 12, the display device 15 executes a power interruption warning display. By executing such a power interruption warning display, even if the power supply is stopped with the power switch 61 remaining on, it is possible to prevent the power supply from being stopped from the next time onwards, for example, by disconnecting the power plug PG from the external power source while the power switch 61 is left on.

Furthermore, the power failure warning effect does not end even if the front door 12 is switched from an open state to a closed state, but ends when a predetermined release condition is met. In other words, the power failure warning effect does not end simply by opening and closing the front door 12; a release condition must be met to end the power failure warning effect, making the power failure warning effect more memorable.

(8) When power supply is started by opening the front door 12 and switching the power switch 61 from the on state to the off state, the display device 15 executes a power-off thank-you performance. In this way, by executing the power-off thank-you performance, it is possible to determine that the power supply has been stopped by switching the power switch 61 from the on state to the off state, i.e., that the power supply was stopped without any problems.

The power-off thank-you performance does not end even if the front door 12 is switched from an open state to a closed state, but ends when a specified release condition is met. In other words, the power-off thank-you performance does not end simply by opening and closing the front door 12; a release condition must be met to end the power-off thank-you performance, making it easier to leave a lasting impression.

(9) The specified release condition is met when the locking unit SJ is operated counterclockwise. In other words, if the locking unit SJ cannot be operated, the release condition cannot be met. For this reason, even if the power supply is stopped in order to commit fraud and then resumed, if the locking unit SJ cannot be operated, the power cut warning display or the power cut thank you display cannot be ended, and fraudulent activity itself can be suppressed.

(10) Even if the power switch 61 is in the OFF state, if the power plug PG is connected to an external power source, power is supplied to the auxiliary power source 73. This makes it possible to reduce the capacitance of the auxiliary power source 73, which contributes to cost reduction.

(11) If the power supply is stopped while freeze control is being performed and then resumed, freeze control is restored and the volume cannot be adjusted even if buttons B1 and B2 are operated for at least a specific period of time. On the other hand, if the power supply is stopped while a variable game is being played and then resumed, freeze control is restored while the variable game is being played and the volume can be adjusted by operating buttons B1 and B2. In this way, depending on whether the volume can be adjusted after the power supply is stopped and then resumed while a variable game is being played, it is possible to determine whether the power supply was stopped while freeze control was being performed or while the variable game was being played. By letting the player understand whether the power supply was stopped while freeze control was being performed or while the variable game was being played, the player can feel reassured and the performance can be executed appropriately.

(12) When the power supply is stopped while the volume is the same as the volume of the stage set by the changeover switch SW, if the power supply is resumed after the power supply is stopped, the volume will continue to be the same as the volume of the stage set by the changeover switch SW. On the other hand, when the power supply is stopped while the volume is other than the volume of the stage set by the changeover switch SW, if the power supply is resumed, the volume will not be other than the volume of the stage set by the changeover switch SW, but will be the same as the volume of the stage set by the changeover switch SW. In other words, regardless of the volume when the power supply was stopped, when the power supply is resumed, the volume will be the same as the volume of the stage set by the changeover switch SW. In this way, when the power supply is resumed, the volume is unified, so that it is possible to suppress the feeling of discomfort caused by the volume being different each time the power supply is resumed, and to appropriately execute the performance.

(13) The stage set by the changeover switch SW can be changed by operating the changeover switch SW. Therefore, for example, the volume when the power supply is resumed can be changed depending on the environment of the game center, and as a result, it becomes possible to execute the performance appropriately.

(14) If the power supply is stopped while freeze control is being performed and then resumed, freeze control is resumed and the volume cannot be adjusted even if buttons B1 and B2 are operated for at least a specific period of time. However, if the power supply is stopped while freeze control is being performed, the volume can be adjusted by operating buttons B1 and B2 before the power supply is stopped and during the period when freeze control is being performed. In this way, if the power supply is stopped while freeze control is being performed and then resumed, the volume cannot be adjusted, unlike before the power supply was stopped. This reduces the awareness of adjusting the volume after the power supply is resumed, making it easier to focus on the freeze control and to enjoy the period when freeze control is being performed.

On the other hand, if the power supply is stopped while the variable game is being played and then resumed, the volume can be adjusted by operating buttons B1 and B2 when the variable game is being played and the power supply is restored during the game. If the power supply is stopped while the variable game is being played, the volume can be adjusted by operating buttons B1 and B2 before the power supply is stopped and during the period when the variable game is being played. In other words, even if the power supply is stopped while the variable game is being played and then resumed, the volume can be adjusted in the same way as before the power supply was stopped. This prevents players from being confused by being unable to adjust the volume while the variable game is being played.

(15) The specific period includes at least the period from when the power supply is resumed to when the freeze control is terminated. In other words, if the power supply is stopped while the freeze control is being performed and then resumed, the freeze control is resumed, and the volume cannot be adjusted even if buttons B1 and B2 are operated at least during the period from when the power supply is resumed to when the freeze control is terminated. As a result, in the case where the volume cannot be adjusted after the power supply is resumed after the power supply is stopped while the freeze control is being performed, a decrease in attention to the freeze control can be suppressed at least until the freeze control is terminated, and interest can be effectively increased.

(16) If the power supply is not stopped during the execution of the variable game, both the background music and the stop sound are output from the speaker 14. However, if the power supply is stopped during the execution of the variable game, after the power supply is resumed, the background music is not output from the speaker 14, while the stop sound is output from the speaker 14. This allows the player to appropriately perform the performance so that it can be determined whether the power supply has been stopped during the execution of the variable game depending on whether the background music is output from the speaker 14. As a result, the player can understand whether the power supply has been stopped during the execution of the variable game, which can reassure the player. On the other hand, the stop sound is output from the speaker 14 in both cases where the power supply is not stopped during the execution of the variable game and where the power supply is stopped during the execution of the variable game. In this way, even if the background music is not output after the power supply is stopped, the stop sound is output, which allows the player to confirm that the speaker 14 is not broken, which can reassure the player.

(17) The stopping sound is output from the speaker 14 when the reels stop spinning. In this way, by configuring the stopping sound output from the speaker 14 when the reels stop spinning to be output even after the power supply is resumed, it is possible to make it easier to feel the joy of stopping the reels spinning in a variable game, and to execute the presentation appropriately.

(18) If the power supply is stopped while freeze control is being performed and then resumed, even if freeze control is restored, a stop sound is not output from speaker 14 while the freeze control is being performed. This makes it possible to determine whether the power supply was stopped during the execution of a variable game or during freeze control by whether a stop sound is output from speaker 14. This allows the player to enjoy the game with peace of mind, knowing whether the power supply was stopped during the execution of a variable game or during freeze control.

(19) If the power supply is stopped while the reels are spinning during freeze control and then resumed, it is possible to return to freeze control and stop the reels from spinning by operating the stop button before the reels reach a constant speed after the power supply is started. Therefore, for example, if the power supply is temporarily stopped during freeze control and then freeze control is returned, the reels can be stopped from spinning before the reels reach a constant speed, reducing the annoyance that may be caused by a temporary power supply interruption and allowing the performance to be executed appropriately. As a result, it is possible to suppress a decrease in interest due to a temporary power supply interruption.

(20) Even if the power supply is temporarily stopped, for example, if the stop button is operated when the reel rotation speed in a variable game has not reached a fixed speed, a symbol combination that should not be stopped may stop, and a prize that was not intended to be awarded may be awarded to the player. It is also possible that fraudulent activity may be committed using this. Therefore, if the power supply is stopped while the reels are spinning during the execution of a variable game and then power supply is started again, it is made impossible to stop the reel rotation even if the stop button is operated at a timing when the power supply is restored during the execution of the variable game and before the reel rotation speed reaches a fixed speed after the power supply is started. This makes it possible to prevent a prize that was not intended to be awarded being awarded to a player, as described above, and to prevent fraudulent activity using this.

(21) When the reels are spinning while freeze control is being performed and the navigation performance is being executed on the performance display device 15, if the power supply is resumed after the power supply is stopped, the freeze control is restored and the reels spin, but the navigation performance is not executed again on the performance display device 15. As a result, if the power supply is resumed after the power supply is stopped while freeze control is being performed, even if the freeze control is restored and the situation returns to one in which the reels are spinning, it is possible to recognize that the power supply was stopped while freeze control was being performed based on the fact that the navigation performance is not being executed again. In other words, when freeze control is being performed and the reels are spinning, the performance can be appropriately executed so that it can be determined whether the power supply was stopped while freeze control was being performed depending on whether the navigation performance is being executed. As a result, it is possible to reassure the player by letting them understand that the power supply was stopped while freeze control was being performed, and the player can enjoy the period during which freeze control is being performed with peace of mind.

(22) If the power supply is stopped and then resumed while the reels are spinning during the execution of a variable game and the navigation effect is being executed on the effect display device 15, the variable game returns to being executed, the reels spin, and the navigation effect is executed again on the effect display device 15. In this way, when the power supply is resumed while a variable game is being executed, not while freeze control is being performed, the navigation effect is executed again in the same manner as when the power supply was stopped. This makes it possible to prevent players from being confused by the navigation effect not being executed in the middle of the execution of a variable game.

(23) Even when the reels are spinning during the execution of a variable game, if the power supply is stopped after the execution of a navigation effect has already finished and then the power supply is resumed, the navigation effect will not be executed again. This prevents players from being confused by a navigation effect that has already finished before the power supply was stopped being executed when the power supply is resumed.

(24) When freeze control is being performed and the reels are rotating and the navigation effect is being executed, if the power supply is stopped and then resumed, a navigation effect is executed before the power supply is stopped, which suggests or notifies the player that the white seven symbol is the target position. That is, before the power supply is stopped, a navigation effect is executed that suggests or notifies the player that the white seven symbol will be displayed in the display window 12a when the reels stop rotating. On the other hand, when freeze control is being performed and the reels are rotating and the power supply is stopped and then resumed, if the power supply is stopped and then resumed, after the power supply is resumed, the navigation effect is not executed again, but a stop promotion effect is executed that prompts the player to stop rotating the reels. That is, when freeze control is being performed and the power supply is stopped and then resumed, the navigation effect is not executed again, but a stop promotion effect is executed that prompts the player to stop rotating the reels. In this way, even if the navigation effect is not executed, the stop promotion effect is executed to prompt the player to stop rotating the reels, and it is possible to prevent the freeze control from being performed without the player knowing what to do.

(25) When freeze control is being performed and the reels are spinning, if a specific symbol combination stops without the power supply being stopped, the performance display device 15 executes the additional performance. On the other hand, when freeze control is being performed and the reels are spinning, if the power supply is stopped and the specific symbol combination stops after the power supply is resumed, the performance display device 15 does not execute the additional performance. However, when freeze control is being performed and the reels are spinning, whether the power supply is not stopped or is stopped, if a specific symbol combination stops, the additional performance is executed. In this way, even if the power supply is stopped when freeze control is being performed and the reels are spinning, and the additional performance is not executed when the specific symbol combination stops after the power supply is resumed, the additional performance is executed, so there is no disadvantage such as not being able to execute the additional performance due to the power supply being stopped. Therefore, even if the power supply is stopped when freeze control is being performed, the player can enjoy the game without feeling anxious, even if the power supply is resumed.

(26) Suppose that the power supply is stopped and then resumed when the reels are spinning during freeze control and the navigation performance is being performed on the performance display device 15. After the power supply is resumed, the freeze control is restored and the reels spin, but the navigation performance is not performed again on the performance display device 15 controlled by the sub-board 50. On the other hand, when the reels are spinning during the execution of a variable game and the navigation performance is being performed on the performance display device 15 and instruction information is being displayed on the payout display unit 37, the power supply is stopped and then resumed. After the power supply is resumed, the variable game is restored and the reels spin, the navigation performance is performed again on the performance display device 15 controlled by the sub-board 50, and instruction information is displayed again on the payout display unit 37 controlled by the main board 40.

This allows the presentation to be performed appropriately so that it is possible to determine whether the power supply has been stopped while the freeze control is being performed, depending on whether the navigation presentation is being performed when the reels are spinning during the freeze control. As a result, the player can be reassured by understanding whether the power supply has been stopped while the freeze control is being performed, and can enjoy the period during which the freeze control is being performed with peace of mind. In addition, when the power supply is resumed during a variable game, the navigation presentation is executed again in the same manner as when the power supply was stopped, and instruction information is displayed, so that it is possible to prevent the player from being confused by the fact that the navigation presentation has stopped being executed while the variable game is being executed. In addition, in the payout display unit 37 controlled by the main board 40, which is generally superior to the sub-board 50 in terms of security, instruction information is displayed when the power supply is resumed, so that a sense of security can be given even if the navigation presentation is not executed in the presentation display device 15.

(27) Even when the reels are spinning during the execution of a variable game, if the execution of a navigation effect has already ended on the effect display device 15 and the power supply is stopped and then resumed, the navigation effect will not be executed again on the effect display device 15. However, even if the power supply is stopped and then resumed when the navigation effect has already ended, the payout display unit 37 controlled by the main board 40 displays instruction information, so that a sense of security can be given even if the navigation effect is not executed on the effect display device 15.

The above embodiment can be modified as follows: The above embodiment and the following modifications can be combined with each other to the extent that no technical contradiction occurs.
Even if the power switch 61 is in the off state, if the power plug PG is connected to an external power source, power may be supplied to the backup power source 63. That is, in a situation where the power plug PG is connected to an external power source, power may be supplied to the backup power source 63 as a memory retention power source. In this case, for example, it is possible to reduce the capacitance of the backup power source 63, which can contribute to cost reduction.

- The content of the performance of the performance display device 15 when power supply is started may be the same when power supply is started as a result of the power switch 61 being switched from the off state to the on state and when power supply is started while the power switch 61 remains on. For example, the power restoration warning performance and the power restoration thank-you performance may not be executed.

- The content of the performance of the performance display device 15 when the power supply is started may be the same in cases where the power supply is stopped as a result of the power switch 61 being switched from the on state to the off state, and in cases where the power supply is stopped while the power switch 61 remains on. For example, the power outage warning performance and the power outage thank-you performance may not be executed.

-When power supply is started when the power switch 61 is switched from the off state to the on state, the power restoration thank-you performance may not be executed. Also, when power supply is started with the power switch 61 remaining on, the power restoration warning performance may not be executed. For example, at least one of the power restoration warning performance and the power restoration thank-you performance may be executable. Even in this case, the performance content of the performance display device 15 when power supply is started may be different when power supply is started when the power switch 61 is switched from the off state to the on state and when power supply is started with the power switch 61 remaining on. Also, it may be configured not to execute both the power restoration thank-you performance and the power restoration warning performance. For example, by configuring not to execute both the power restoration thank-you performance and the power restoration warning performance, the performance content of the performance display device 15 when power supply is started may be the same when power supply is started when the power switch 61 is switched from the off state to the on state and when power supply is started with the power switch 61 remaining on.

- A method other than that of the above embodiment may be used as a method for determining whether the power switch 61 is in an on state or an off state. For example, a method may be used in which a sensor capable of physically detecting whether the power switch 61 is in an on state or an off state is provided, and whether the power switch 61 is in an on state or an off state is determined based on a signal from the sensor.

・The power restoration warning performance may be configured not to end even if the front door 12 is switched from an open state to a closed state. For example, the power restoration warning performance may be configured to end when a predetermined release condition is met. For example, the power restoration warning performance may be configured to end when the locking unit SJ is operated counterclockwise. The power restoration thank-you performance may also be configured not to end even if the front door 12 is switched from an open state to a closed state. For example, the power restoration thank-you performance may be configured to end when a predetermined release condition is met. At least one of the power interruption warning performance and the power interruption thank-you performance may be configured to end with the passage of a predetermined performance execution time. For example, the method of ending each of the power restoration warning performance and the power restoration thank-you performance may be the same as in the above embodiment, or may be different. For example, the method of ending the power restoration warning performance may be configured to be more difficult than the method of ending the power restoration thank-you performance. For example, the power restoration warning display ends when the front door 12 switches from an open state to a closed state and the locking unit SJ is operated counterclockwise, whereas the power restoration thank-you display may be configured to end after a predetermined display execution time has elapsed.

- The power failure warning performance may be configured to end, for example, when the front door 12 is switched from an open state to a closed state even if a predetermined release condition is met, but not when the front door 12 is switched from an open state to a closed state. Similarly, the power failure thank-you performance may be configured to end, for example, when the front door 12 is switched from an open state to a closed state even if a predetermined release condition is met. At least one of the power failure warning performance and the power failure thank-you performance may be configured to end with the passage of a predetermined performance execution time. For example, the method of ending each of the power failure warning performance and the power failure thank-you performance may be the same as in the above embodiment, or may be different. For example, the method of ending the power failure warning performance may be configured to be more difficult than the method of ending the power failure thank-you performance. For example, the power failure warning effect ends when the front door 12 switches from an open state to a closed state and the locking unit SJ is operated counterclockwise, whereas the power failure thank-you effect may be configured to end after a predetermined effect execution time has elapsed.

- The method for ending the power restoration warning display and the method for ending the power interruption warning display may be the same. Also, the method for ending the power restoration thank-you display and the power interruption thank-you display may be the same. For example, the method for ending each of the power restoration warning display and the power interruption warning display may be configured to be more difficult than the method for ending each of the power restoration thank-you display and the power interruption thank-you display. Also, the methods for ending each of the power restoration warning display, the power interruption warning display, the power restoration thank-you display, and the power interruption thank-you display may all be the same.

- The volume may be adjustable even if the power supply is stopped and then resumed while freeze control is being performed. If the power supply is stopped and then resumed while a variable game is being played, the volume may be made unadjustable even if buttons B1 and B2 are operated for at least a specific period of time.

- The specific period may be changed. The specific period may be, for example, the period from when power supply is resumed until freeze control ends. The specific period may be, for example, any of the following: the period until a predetermined regulated time has elapsed, the period until a predetermined number of variable games have ended, and the period until freeze control is executed again.

- If power supply is stopped while the volume is at a level other than the volume level set by the changeover switch SW, and then power supply is resumed, the volume may be configured to be the same as the volume level when power supply was stopped, i.e., the volume level may be the same as when power supply was stopped.

- The changeover switch SW may not be provided. For example, if the power supply is stopped when the volume is the same as the predetermined volume and then resumed, the volume continues to be the same as the predetermined volume. On the other hand, if the power supply is stopped when the volume is other than the predetermined volume and then resumed, the volume may be the same as the predetermined volume, not the volume other than the predetermined volume. In this case, the predetermined volume can be said to correspond to a specific volume. Note that the specific volume does not have to be either the volume level set by the changeover switch SW or a predetermined volume. For example, the specific volume may be a volume that is randomly determined when power supply is started, or a volume that can be set when power supply is started.

- During the period when freeze control is being performed, the volume may be configured to be unadjustable even if buttons B1 and B2 are operated. However, in this case, if the power supply is stopped while freeze control is being performed and then power supply is resumed and freeze control is restored, the volume may be configured to be adjustable by operating buttons B1 and B2 during the period when the freeze control is being performed. Similarly, during the period when a variation game is being performed, the volume may be configured to be unadjustable even if buttons B1 and B2 are operated. However, in this case, if the power supply is stopped while a variation game is being performed and then power supply is resumed and the variation game is restored, the volume may be configured to be adjustable by operating buttons B1 and B2 during the execution of the variation game.

- If the power supply is stopped while the variable game is being executed, the background music may be configured to be output from the speaker 14 after the power supply is resumed. If the power supply is stopped while the variable game is being executed, the background music may be configured to be output from the speaker 14 after the power supply is resumed. If the power supply is stopped while the variable game is being executed, the background music may be configured to be output after the power supply is resumed. Also, if the variable game is being executed, the background music may be configured to be output after the power supply is stopped.

- If the power supply is stopped while freeze control is being performed, the background music may be configured to be output from the speaker 14 after the power supply is resumed. If the power supply is stopped while freeze control is being performed, the background music may be configured to be output from the speaker 14 after the power supply is resumed. If the power supply is stopped while freeze control is being performed, the background music may be configured to be output without regard to whether the power supply was stopped while the freeze control is being performed.

- If the power supply is stopped while a variable game is being played, the sound equivalent to the specific sound that is not output from the speaker 14 after the power supply is resumed does not have to be background music. The sound equivalent to the specific sound may be, for example, a stop sound. The sound equivalent to the specific sound may be, for example, a sound related to an effect that is executed according to the result of a role selection. The specific sound referred to here can also be said to be a specific sound that is not output from the speaker 14 after the power supply is resumed if the power supply is stopped while freeze control is being performed.

- Even if the power supply is stopped during the execution of a variable game, the sound equivalent to the non-specific sound output from the speaker 14 after the power supply is resumed does not have to be a stop sound. The sound equivalent to the non-specific sound may be, for example, background music. The sound equivalent to the non-specific sound may be, for example, a sound related to an effect that is executed according to the result of the role selection. The non-specific sound referred to here can also be a non-specific sound that is not output from the speaker 14 after the power supply is resumed when the power supply is stopped while freeze control is being performed.

- The stop sound output from speaker 14 when the reels stop spinning during execution of a variable game may be different from the stop sound output from speaker 14 when the reels stop spinning when freeze control is being performed. In other words, the non-specific sound output when the reels stop spinning during execution of a variable game may be configured to be different from the non-specific sound output when the reels stop spinning when freeze control is being performed. When configured in this way, if the power supply is stopped while freeze control is being performed and then resumed, the freeze control is restored, but even if the stop sound was not output from speaker 14 while the freeze control was being performed, the discomfort felt by the fact that the stop sound is not being output can be reduced.

- In the stagnation effect processing, regardless of whether the power supply was stopped while the freeze control was being performed, even if the speed at which the reels rotate has not reached a constant speed, the reels may be stopped by operating the stop button. For example, the stagnation effect processing may be configured to perform the processing of step S206 and then the processing of step S208, without going through the processing of step S207.

-When freeze control is being performed and the reels are rotating, if the power supply is stopped and then resumed, the freeze control may be restored, and the reels may be stopped by operating the stop button at a timing after the reels have reached a constant speed since the power supply was started. Also, when power supply is stopped and then resumed while the reels are rotating during a variable game, the freeze control may be restored, and the reels may be stopped by operating the stop button at a timing before the reels have reached a constant speed since the power supply was started. For example, whether freeze control is being performed or a variable game is being performed, the reels may be stopped by operating the stop button at a timing after the power supply is stopped and then resumed while the reels are rotating, and then the reels may be stopped.

- Even if the power supply is stopped while freeze control is being performed and the reels are spinning, when the power supply is subsequently resumed, the freeze control may be restored but the reels may not spin. In this case, for example, when the freeze control is restored, the process may be resumed from step S211.

-When the reels are spinning during freeze control and the navigation performance is being executed on the performance display device 15, if the power supply is stopped and then resumed, the freeze control is restored, the reels spin, and the navigation performance is executed again on the performance display device 15. At this time, the navigation performance executed when the power supply is resumed may be the same as the navigation performance when the power supply is stopped, or may be a navigation performance with a different execution mode from the navigation performance when the power supply is stopped. To change the execution mode, for example, the image displayed on the performance display device 15 when the navigation performance is executed may be different, or the display area in which the navigation image NG is displayed may be different. For example, when the reels are spinning during freeze control and the navigation performance is being executed, if the power supply is stopped and then resumed, the navigation performance may be executed to suggest or notify the white seven symbol as the target position, both before the power supply is stopped and after the power supply is resumed.

- If the power supply is stopped and then resumed while the reels are spinning while freeze control is being performed and a navigation effect is being executed on the effect display device 15, the freeze control may be restored and the reels may spin, and neither the navigation effect nor the stop promotion effect may be executed on the effect display device 15. In other words, the slot machine 10 does not have to be configured to be able to execute a stop promotion effect.

- If the power supply is stopped while the reels are spinning during the execution of the variable game and the navigation effect is being executed on the effect display device 15, and then the power supply is resumed, the variable game may return to execution and the reels may spin, but the navigation effect may not be executed again on the effect display device 15. In this case, after the power supply is resumed, the effect display device 15 may be configured to execute a stop promotion effect, or to execute neither the navigation effect nor the stop promotion effect.

- Even when the reels are spinning during the execution of a variable game, if the power supply is stopped after the execution of a navigation effect has already finished and then resumed, the navigation effect may be executed again. Also, even when the reels are spinning during the execution of a variable game, if the power supply is stopped after the execution of a navigation effect has already finished and then resumed, the navigation effect may not be executed, but a stop prompt effect may be executed. Also, even when the reels are spinning during the execution of a variable game, if the power supply is stopped after the execution of a navigation effect has already finished and then resumed, the instruction information may not be displayed on the payout display unit 37.

- In the case where the power supply is stopped and then resumed while the reels are spinning during the execution of the variable game and the navigation performance is being executed on the performance display device 15 and instruction information is being displayed on the payout display unit 37, the following configuration may be adopted. For example, after the power supply is resumed, the reels may be rotated as the variable game is executed again, the navigation performance is not executed again on the performance display device 15 controlled by the sub-board 50, and the instruction information is displayed again on the payout display unit 37 controlled by the main board 40. In addition, after the power supply is resumed, the reels may be rotated as the variable game is executed again, the navigation performance is executed again on the performance display device 15 controlled by the sub-board 50, and the instruction information is not displayed again on the payout display unit 37 controlled by the main board 40. Also, after the power supply is resumed, the variable game may be resumed while the reels are spinning, and the navigation effect may not be executed again on the effect display device 15 controlled by the sub-board 50, and the instruction information may not be displayed again on the payout display unit 37 controlled by the main board 40.

- When the reels are spinning during the execution of a variable game, and the navigation performance is being executed on the performance display device 15, and instruction information is being displayed on the payout display unit 37, if the power supply is stopped and then resumed, the instruction information is displayed again on the payout display unit 37 controlled by the main board 40. On the other hand, when the reels are spinning during the execution of a variable game, and the navigation performance on the performance display device 15 has already ended, and instruction information is being displayed on the payout display unit 37, if the power supply is stopped and then resumed, the instruction information may be configured not to be displayed again on the payout display unit 37 controlled by the main board 40.

- During execution of a variable game, a navigation effect may be executed that suggests or notifies a player of a specific symbol (e.g., a white seven symbol) as a target position. When freeze control is being performed, a navigation effect may be executed that suggests or notifies the player of the order in which to press the stop buttons. In addition, the navigation effect may be configured to suggest or notify a player of a specific symbol as a target position, and to suggest or notify the player of the order in which to press the stop buttons. For example, when freeze control is being performed, a navigation effect may be executed that suggests or notifies the player of a white seven symbol as a target position, and to suggest or notify the player of the order in which to press the stop buttons.

- If the power supply is stopped while freeze control is being performed and the reels are spinning, and if a specific symbol combination stops after the power supply is resumed, the performance display device 15 may be configured to execute an additional performance. In addition, it may be configured to perform an additional performance.

- In the above embodiment, if the power supply is stopped while the freeze control is being performed and the reels are spinning, and if the specific symbol combination stops after the power supply is resumed, the added performance is not executed on the performance display device 15. At this time, the configuration may be such that no added performance is performed, i.e., no bonus is awarded.

- The freeze control may be configured so that the reels do not spin. For example, the freeze control may be configured to perform control to measure a predetermined freeze time, thereby restricting the game progress main processing from proceeding until the predetermined freeze time has elapsed, and performing control to slow down the progress of the game.

- In the above embodiment, when freeze control is performed, the freeze control is configured to execute an effect in which the reels spin and then stop once, but it may also be configured to execute an effect in which the reels spin and then stop multiple times. In other words, the reel effect may be configured to start spinning the reels multiple times.

- The navigation performance may be configured to be executed by some or all of the performance devices among the decorative lamps 13, the speakers 14, and the performance display device 15. The stop promotion performance may be configured to be executed by some or all of the performance devices among the decorative lamps 13, the speakers 14, and the performance display device 15. The power outage warning performance may be configured to be executed by some or all of the performance devices among the decorative lamps 13, the speakers 14, and the performance display device 15. The power outage thank-you performance may be configured to be executed by some or all of the performance devices among the decorative lamps 13, the speakers 14, and the performance display device 15. The power restoration warning performance may be configured to be executed by some or all of the performance devices among the decorative lamps 13, the speakers 14, and the performance display device 15. The power restoration thank-you performance may be configured to be executed by some or all of the performance devices among the decorative lamps 13, the speakers 14, and the performance display device 15. For example, the performance device on which the power outage thank-you performance is executed may be different from some or all of the performance devices on which the power restoration warning performance is executed. The opening performance may also be configured to be executed by some or all of the performance devices among the decorative lamps 13, the speakers 14, and the performance display device 15. For example, the opening performance may be configured to be executed by the decorative lamps 13 and the speakers 14. In this case, the timing at which the opening performance of the decorative lamps 13 and the opening performance of the speakers 14 end may be different.

- When power supply is started when the power switch 61 is switched from off to on, it is assumed that the front door 12 is opened in order to operate the power switch 61, and as a result, the opening effect is executed. On the other hand, when power supply is started with the power switch 61 remaining on, it is assumed that the front door 12 is closed because the power switch 61 is not operated, and as a result, the opening effect is not executed. As a result, whether or not the opening effect is executed differs, and the performance content of the performance device that executes the opening effect differs. In other words, whether or not the opening effect is executed differs between when power supply is started when the power switch 61 is switched from off to on and when power supply is started with the power switch 61 remaining on, and as a result, the performance content of the performance device that can execute the opening effect differs.

・The opening performance does not end even if the front door 12 switches from an open state to a closed state. For example, the opening performance may end when a predetermined release condition is met. That is, the opening performance may be configured to end when the locking unit SJ is operated counterclockwise. Also, when the front door 12 is open, information that can identify that the front door 12 is open (hereinafter referred to as opening error information) may be stored and held in the error memory unit. The error memory unit here may be either one of the main RWM 43 and the sub RWM 53, or both. The opening error information may be stored and held in the error memory unit even if the power supply is stopped. And, when the power supply is stopped while the front door 12 is open and then resumed, even if the front door 12 is closed, the opening performance may be executed based on the stored and held opening error information. And, when the opening performance is executed based on the opening error information when the power supply is resumed, the opening performance may be ended by operating the locking unit SJ counterclockwise. When the power supply is stopped as a result of the power switch 61 being switched from the on state to the off state, it is assumed that the front door 12 is opened in order to operate the power switch 61, and the opening performance is being performed. Therefore, when the power supply is stopped as a result of the power switch 61 being switched from the on state to the off state, it can be assumed that the power supply is stopped while the opening performance is being performed. As a result, when the power supply is stopped as a result of the power switch 61 being switched from the on state to the off state, the opening performance is performed when the power supply is resumed. On the other hand, when the power supply is stopped while the power switch 61 remains on, it can be assumed that the front door 12 is closed because the power switch 61 is not operated, and as a result, the opening performance is not performed. As described above, when the power supply is stopped as a result of the power switch 61 being switched from the on state to the off state, the presence or absence of the opening performance is different from the presence or absence of the opening performance, and the performance content of the performance device capable of performing the opening performance is different. When the open error information is stored in the main RWM 43, the open error information may be configured to be erased when the main initial startup process is performed. When the open error information is stored in the sub RWM 53, the open error information may be configured to be erased when the sub initial startup process is performed.

- The volume does not have to be adjustable. The intensity of the light emitted by the decorative lamp 13 may be adjustable. Adjusting the intensity of the light emitted by the decorative lamp 13 is sometimes referred to as adjusting the amount of light or adjusting the brightness. In addition to adjusting the tone, the intensity of the light emitted by the decorative lamp 13 may be adjustable.

- The volume may be configured to be initialized when power supply is started. For example, the volume may be configured to be initialized to the volume level set by the changeover switch SW when power supply is started. For example, in both the sub-initial startup process and the sub-backup process, the secondary CPU 51 may update the volume information to identify the level set by the changeover switch SW.

The above embodiment may be applied to a slot machine in which a bonus game is generated (awarded) when a symbol combination (bonus stop) corresponding to a bonus role is derived in a variable game. The period during which the bonus game is generated may be configured to be included in an advantageous zone. Incidentally, in a slot machine capable of generating a bonus game, the state in which the winning of a bonus role is permitted is also called a "carry-over state" or "inside state."

The slot machine 10 may be a gaming machine that can impose a penalty that causes a disadvantage to the player. The penalty may be imposed on one or multiple variation games.

-Even if the bet is set to a number less than three coins, it may be possible to configure it so that a variable game can be played. Also, the number of medals paid out may be varied according to the bet. Also, the probability that some or all of the multiple types of winning combinations are allowed may be varied according to the bet.

- The slot machine 10 may be a gaming machine that uses a gaming medium other than medals. For example, it may be embodied as a gaming machine that uses gaming balls (pachinko balls) as the gaming medium. In addition, the gaming medium may be managed by data (information). In other words, the slot machine 10 may be a so-called managed gaming machine.

- The slot machine 10 may be embodied as a pachinko gaming machine. In pachinko gaming machines, a jackpot game generally occurs after a jackpot lottery is won. In pachinko gaming machines, if the power supply to the main board 40 and the sub-board 50 is stopped as a result of the power plug PG being disconnected from the external power source while the power switch 61 is on, the power may become unstable, causing overvoltage, etc., which may cause a malfunction. In pachinko gaming machines, if the power supply to the main board 40 and the sub-board 50 is started as a result of the power plug PG being connected to the external power source while the power switch 61 is on, the power may become unstable, causing overvoltage, etc., which may cause a malfunction.

- There may be only one type of setting value. Even if there are multiple types of setting values, some of the multiple setting values may be configured to use the same role selection table in the role selection. In addition, the setting values do not need to be configured to be changeable.

The functions of the main board 40 in the above embodiment may be realized by dividing them into multiple boards. Also, the main CPU 41 may be composed of multiple CPUs mounted on a single board.

- The functions of the sub-board 50 in the above embodiment may be realized by dividing them into multiple boards. For example, a display board that specializes in controlling the performance display device 15, a sound board that specializes in controlling the speaker 14, and a lamp board that specializes in controlling the decorative lamps 13 may be provided, and a master board that provides overall control over these boards may also be provided. The sub-CPU 51 may also be composed of multiple CPUs implemented on a single board.

Next, the technical ideas that can be understood from the above embodiment and other examples will be described below.
(i) The device is provided with a bonus granting means for granting a bonus, and when the freeze control is being performed and the reels are spinning and a specific symbol combination stops without the power supply being stopped, the performance execution means executes a bonus granting performance that suggests or notifies the player that the bonus will be granted, and when the bonus is granted and the power supply is stopped while the freeze control is being performed and the reels are spinning, if the specific symbol combination stops after the power supply is resumed, the performance execution means does not execute the bonus granting performance but grants the bonus.
