Description

The present invention relates to a slot machine.

A slot machine is equipped with a main control board that controls the progress of the game using multiple reels (also called "cylinders") (for example, driving control of the reels, control of the determination of winning combinations, control of the payout of gaming media (for example, medals), and control of the mode and game state), and a sub-control board that controls the presentation aimed at increasing interest in the game depending on the game situation (for example, displaying images on an image display device, turning on or off lamps, and emitting sound from a speaker), and communication between the two boards is only one-way, from the main control board to the sub-control board.

In addition, after a specified number of medals are bet on a slot machine, the start lever is operated to determine the winning combination and the multiple reels begin to spin. Once the multiple reels have started to spin and have reached a specified rotation speed, the operation of the stop button provided for each of the multiple reels becomes effective, and operating the stop button stops the rotation of the corresponding reel. Then, when a winning combination is achieved, medals are paid out.

Recently, slot machines have become known that have a normal mode, a pseudo bonus, and an ST mode in which it is easier to win the pseudo bonus than in the normal mode (for example, see Patent Document 1). In such slot machines, the pseudo bonus is drawn while the player is in the normal mode, and if the player wins the pseudo bonus, the player can play with the pseudo bonus. And if the player wins the ST mode draw while the player is in the pseudo bonus, the player can play in the ST mode.

Here, the slot machine shown in Patent Document 1 has multiple ST modes with different pseudo bonus drawing probabilities, so it is possible to diversify the transition to the pseudo bonus.

JP 2016-41293 A

However, with this type of slot machine, if a player wins the ST mode lottery while in the pseudo bonus mode, they can play in ST mode, but since they have to win the ST mode lottery after winning the pseudo bonus from the normal mode, this presents a high hurdle for players. Also, if the conditions for transitioning to ST mode are met while in the normal mode, the game will transition from normal mode to ST mode, but there is a problem in that it is difficult to know which mode to expect while in the normal mode.

The present invention was made in consideration of these circumstances, and aims to provide a slot machine that makes it easy to understand which mode a player can expect to transition to.

In order to solve such problems, the slot machine of the present invention is a slot machine equipped with a game control means for controlling the game and a presentation control means for controlling the presentation, the game control means being equipped with a mode control means for controlling an unfavorable mode that is unfavorable to the player and an advantageous mode that is favorable to the player compared to the unfavorable mode, and a transition drawing means for drawing a transition to the advantageous mode in the unfavorable mode, the unfavorable modes being provided with a normal mode, a specific mode different from the normal mode, and a CZ mode in which it is easier to win the transition drawing to the advantageous mode than in the normal mode, the advantageous modes being provided with a first advantageous mode and a second advantageous mode different from the first advantageous mode, the transition drawing means being characterized in that in the normal mode, when a predetermined role is won, a drawing is made to determine whether or not to transition to the first advantageous mode, but a drawing is not made to determine whether or not to transition to the second advantageous mode, and in the specific mode, when the predetermined role is won, a drawing is made to determine whether or not to transition to the second advantageous mode.

In addition, in the slot machine according to the present invention, the presentation control means performs control to suggest or notify the specific mode when the specific mode is being controlled by the mode control means.

The slot machine according to the present invention is characterized in that the specific modes include a first specific mode and a second specific mode that is more advantageous to the player than the first specific mode.

The present invention provides a slot machine that makes it easy to know which mode a player can expect to transition to.

<Transition diagram of gaming state of slot machine 1>
As shown in FIG. 4, the slot machine 1 has a general gaming state, an RT gaming state, and a combination game state. The general gaming state is a gaming state that is disadvantageous to the player. When the general gaming state is in effect, if condition α is satisfied, the state transitions to the combination game state, and when condition β is satisfied, the state transitions to the RT gaming state. Here, the condition α is that BB is displayed on a winning line (in this embodiment, the line connecting the lower part of the left reel 6, the middle part of the middle reel 7, and the upper part of the right reel 8) (hereinafter, the display of a combination of symbols on a winning line is referred to as a "winning combination"), and the condition β is that BB is a winning combination, and BB does not win on a winning line.

The RT gaming state is a gaming state in which the probability that the result of the role determination will result in a replay is higher than in the general gaming state. Here, in the slot machine 1 of this embodiment, as a rule, the gaming state does not transition after transitioning to the RT gaming state. As an exception, when the main RAM 400 is cleared, the gaming state is initialized and the general gaming state is entered.

The consecutive role play state is a play state in which the consecutive role play device is operating. Here, if condition γ is met while remaining in the consecutive role play state, the state transitions to the general play state. Here, condition γ is that more than a prescribed number of medals are paid out. The consecutive role play device may be a consecutive role play device related to a first type special role, or a consecutive role play device related to a second type special role.

<Numbers assigned to each condition device>
As shown in FIG. 5, the number of positions assigned to each condition device is shown as an example of the probability of determining a winning combination. Here, the number of positions assigned to each condition device is assigned for each game state. In this embodiment, the number of positions corresponding to each of the general game state, RT game state, and consecutive game state is specified for each setting value. As an example, the number of positions assigned to each condition device when the setting value is 1 and the number of positions assigned to each condition device when the setting value is 6 are shown, and the number of positions assigned to each condition device when the setting value is other (setting values 2 to 5) is omitted. The number of positions assigned to each condition device is stored in the main ROM 300.

Figure 5 also shows the number of medals placed when the maximum allowable number of medals is bet. Although not shown, the number of medals placed varies depending on the number of medals bet. Specifically, the number of medals placed is allocated so that the more medals are bet, the more advantageous it is for the player.

<Mode transition diagram>
8, a plurality of modes are defined for the slot machine 1. Specifically, a reset mode, a normal mode, an F premonition mode, a CZ premonition mode, a BB premonition mode, a direct hit mode, a CZ mode, a red BB mode, a blue BB mode, an AT mode, and a pull-back mode are defined.

Note that the CZ precursor mode, BB precursor mode, and F precursor mode may be referred to simply as "precursor modes," and the red BB mode and blue BB mode may be referred to simply as "BB modes."

The reset mode is a mode to which the player transitions when the settings are changed, or from the BB mode or AT mode. If transition condition A is met while the player is in the reset mode, the player transitions to the normal mode. Transition condition A is that a predetermined number of games (32 games in this embodiment) have been played in the reset mode.

Normal mode is the mode in which the CZ mode and BB mode lotteries are held. Here, if transition condition B is met while in normal mode, the mode will transition to CZ precursor mode, if transition condition C is met, the mode will transition to BB precursor mode, if transition condition D is met, the mode will transition to F precursor mode, and if transition condition E is met, the mode will transition to direct hit mode.

Transition condition B is winning the CZ mode transition lottery, transition condition C is winning the BB mode transition lottery or the value of the ceiling game number counter 416 described below reaching 0, transition condition D is winning a rare role (specifically, weak cherry, strong cherry, watermelon, weak chance role, or strong chance role), and transition condition E is winning the direct hit mode transition lottery.

The F premonition mode is the mode to which the player enters if a rare role is won while in the normal mode, but the player does not win the lottery in the CZ mode or the lottery in the BB mode. If transition condition F is met while in the F premonition mode, the player enters the BB premonition mode, and if transition condition G is met, the player enters the normal mode. Transition condition F is when the player wins the rewrite lottery in the BB premonition mode, or when the value of the ceiling game number counter 416 described below becomes 0, and transition condition G is when a predetermined number of games have been played while in the F premonition mode.

CZ premonition mode is the mode you switch to when you win the CZ mode lottery while in normal mode and before switching to CZ mode. Here, if transition condition H is met while in CZ premonition mode, you switch to CZ mode, and if transition condition I is met, you switch to BB premonition mode.

Transition condition H is when a predetermined number of games have been played in the CZ premonition mode, and transition condition I is when the value of the ceiling game number counter 416, which will be described later, reaches 0.

The BB premonition mode is a mode that is entered when a BB mode lottery is won in the normal mode and before the mode transitions to the BB mode. Here, if transition condition J is met while in the BB premonition mode, the mode transitions to the BB mode. The transition condition J is that a predetermined number of games have been played in the BB premonition mode.

Compared to normal mode, CZ mode is a mode that makes it easier for the player to transition to a more advantageous mode (BB mode in this embodiment). Here, if transition condition K is met while in CZ mode, the player transitions to BB mode, and if transition condition L is met, the player transitions to normal mode. Transition condition K is when the player wins the BB mode transition lottery or the value of the ceiling game number counter 416 described below becomes 0, and transition condition L is when a predetermined number of games have been played in CZ mode and the player has not won BB mode.

Direct hit mode is the mode in which the AT mode lottery is held. Here, if transition condition M is met while in direct hit mode, the mode transitions to BB mode, if transition condition N is met, the mode transitions to AT mode, and if transition condition O is met, the mode transitions to normal mode. Note that transition condition M is when the value of the ceiling game number counter 416 described below becomes 0, transition condition N is when the AT mode transition lottery is won, and transition condition O is when a predetermined number of games are played while in direct hit mode.

Red BB mode is a so-called pseudo bonus, in which the operation order of the left stop button 9, the middle stop button 10, and the right stop button 11 is announced when the result of the role determination is a push order bell. In addition, in red BB mode, a lottery for the AT mode is held according to the result of the role determination. Here, if transition condition P is met while in red BB mode, the mode transitions to the AT mode, and if transition condition Q is met, the mode transitions to the reset mode. Note that transition condition P is that the AT mode lottery has been won by the end of red BB mode, and transition condition Q is that the AT mode lottery has not been won by the end of red BB mode.

Blue BB mode is a so-called pseudo bonus mode in which the operation order of the left stop button 9, middle stop button 10, and right stop button 11 is announced when the result of the role determination is a push order bell. In addition, in blue BB mode, a lottery for the AT mode is held according to the result of the role determination. Here, if transition condition P is met while in blue BB mode, the mode transitions to AT mode, and if transition condition Q is met, the mode transitions to reset mode. Note that transition condition P is that the AT mode lottery has been won by the end of blue BB mode, and transition condition Q is that the AT mode lottery has not been won by the end of blue BB mode.

In AT mode, when the result of the role determination is a push order bell, the operation order of the left stop button 9, the middle stop button 10, and the right stop button 11 is notified. Here, when transition condition R is met, the mode transitions to the pull-back mode, and when transition condition S is met, the mode transitions to the reset mode. Transition condition R is winning the lottery for transitioning to the pull-back mode at the end of the AT mode, and transition condition S is not winning the lottery for transitioning to the pull-back mode at the end of the AT mode.

The pull-back mode is a mode in which it is easier to transition to the AT mode than the normal mode. Here, in the pull-back mode, if transition condition T is met, the mode transitions to the AT mode, and if transition condition U is met, the mode transitions to the reset mode. Note that transition condition T is that the pull-back lottery has been won, and transition condition U is that the predetermined number of games have been played without winning the pull-back lottery.

<Numbers used in normal mode>
FIG. 9 shows the numbers stored in the main ROM 300 for use in the normal mode.

Figure 9 shows the number of symbols assigned to the lottery in CZ mode (see Figure 9 (A)). In this embodiment, if the result of the role determination is weak cherry or watermelon, a lottery is held to determine whether or not to transition to CZ mode. Also, in this embodiment, the higher the set value, the easier it is to win the lottery to determine whether or not to transition to CZ mode.

Also, FIG. 9 shows the number of symbols assigned to the lottery in BB mode (see FIG. 9(B)). Here, in this embodiment, when the result of the role determination is a strong cherry, a weak chance role, or a strong chance role, a lottery is held to determine whether or not to transition to BB mode. Also, in this embodiment, the higher the set value, the easier it is to win the lottery to determine whether or not to transition to BB mode.

Figure 9 also shows the number of places allocated to the drawing of the number of premonition games (see Figure 9 (C)). Here, in this embodiment, the number of places allocated to the drawing of the number of premonition games is used to determine the number of premonition games when a lottery to determine whether or not to transition to CZ mode is won, when a lottery to determine whether or not to transition to BB mode is won, or when transitioning to F premonition mode is won.

Figure 9 also shows the number of symbols assigned to the direct hit mode lottery (see Figure 9 (D)). In this embodiment, a lottery is held to determine whether or not to transition to direct hit mode when the result of the role determination is a strong cherry, a weak chance role, or a strong chance role. In this embodiment, the higher the set value, the easier it is to win the lottery to determine whether or not to transition to direct hit mode.

<Numbers used in F Premonition Mode>
FIG. 10 shows the numbers stored in the main ROM 300 and used in the F precursor mode.

Figure 10 shows the number of settings allocated to rewriting the premonition mode. Here, in this embodiment, if the result of the role determination is a strong cherry, a watermelon, a weak chance role, or a strong chance role, a lottery is held to determine whether or not to rewrite to the BB premonition mode. Also, in this embodiment, the higher the set value, the easier it is to win the lottery to determine whether or not to rewrite to the BB premonition mode.

<Numbers used in BB Premonition Mode>
FIG. 11 illustrates the numbers stored in the main ROM 300 that are used in the BB precursor mode.

Figure 11 shows the numbers used in the promotion lottery. In this embodiment, when it has been decided to transition to red BB mode, the promotion lottery is held if the result of the role determination is weak cherry, strong cherry, watermelon, weak chance role, or strong chance role, and if this promotion lottery is won, it is decided to transition to blue BB mode. Also, in this embodiment, the higher the set value, the easier it is to win the lottery to decide whether or not to rewrite to blue BB mode.

<Numbers used in CZ mode>
FIG. 12 shows the numbers stored in the main ROM 300 for use in the CZ mode.

Figure 12 shows the number of symbols used in the drawing for the BB mode in the CZ mode. In this embodiment, the drawing for the BB mode is performed when the result of the role determination is a weak cherry, a strong cherry, a watermelon, a weak chance role, or a strong chance role.

<Numbers used in direct hit mode>
FIG. 13 shows the numbers stored in the main ROM 300 for use in the direct hit mode.

Figure 13 shows the number of symbols used in the drawing for the AT mode in the direct hit mode. In this embodiment, the drawing for the AT mode is performed when the result of the role determination is a weak cherry, a strong cherry, a watermelon, a weak chance role, or a strong chance role.

<Numbers used in BB mode>
FIG. 14 shows the numbers stored in the main ROM 300 for use in the BB mode.

Figure 14 shows the numbers used for the AT mode lottery in red BB mode (see Figure 14 (A)). In this embodiment, the lottery for the AT mode is performed when the result of the role determination is a weak cherry, a strong cherry, a watermelon, a weak chance role, or a strong chance role.

Figure 14 also shows the numbers used in the AT mode drawing in blue BB mode (see Figure 14 (B)). Here, in this embodiment, the drawing for AT mode is performed when the result of the role determination is weak cherry, strong cherry, watermelon, weak chance role, or strong chance role. It is easier to win the AT mode in blue BB mode than in red BB mode. Therefore, it can be said that blue BB mode is a more advantageous mode than red BB mode.

<Numbers used in AT mode>
FIG. 15 shows the numbers stored in the main ROM 300 and used in the AT mode.

Figure 15 shows the numbers used in the additional draw (see Figure 15 (A)). In this embodiment, the additional draw is performed when the result of the role determination is a weak cherry, a strong cherry, a watermelon, a weak chance role, or a strong chance role.

Figure 15 also shows the numbers used in the scenario drawing (see Figure 15 (B)). In this embodiment, scenarios 1 to 11 are specified, and if the result of the role determination is a rare role, the selected scenario determines whether or not to freeze.

In this embodiment, while the freeze is being executed, the left reel 6, middle reel 7, and right reel 8 will not stop spinning even if the left stop button 9, middle stop button 10, or right stop button 11 is operated. The freeze may also be implemented by preventing the left reel 6, middle reel 7, and right reel 8 from spinning for a predetermined period of time when the start lever 5 is operated. Alternatively, a reel effect may be implemented in which an effect is performed using the left reel 6, middle reel 7, and right reel 8.

Also shown in FIG. 15 is a scenario map (see FIG. 15(C)). Here, the scenario map specifies whether or not to freeze depending on each scenario and the value of the scenario counter 426 described below. For example, if the first scenario is selected, a rare combination is won, and the value of the scenario counter 426 described below is 4, it is decided to freeze. On the other hand, if the first scenario is selected, a rare combination is won, and the value of the scenario counter 426 described below is 3, it is decided not to freeze.

When a scenario is determined using the scenario map, whether or not to freeze is determined first when the result of the role determination is a rare role. In this embodiment, whether or not to freeze is determined first until the result of the role determination is a rare role four times, but this number does not have to be four, and may be one time, or a number other than four times.

Figure 15 also shows the numbers used in the drawing at the time of freezing (see Figure 15 (D)). In this embodiment, a number corresponding to the time of freezing is assigned to each rare role that triggered the freezing. For example, when the result of the role determination is a weak cherry, if it is decided to execute a freeze, the time for executing the freeze is decided to be 3 seconds, with a probability of 30,000/65,536.

In addition, in this embodiment, the number of games to be added is determined according to the time when the freeze is executed. Specifically, if the freeze is executed for 3 seconds, 10 games are determined as the number of games to be added, if the freeze is executed for 6 seconds, 20 games are determined as the number of games to be added, if the freeze is executed for 9 seconds, 30 games are determined as the number of games to be added, if the freeze is executed for 12 seconds, 50 games are determined as the number of games to be added, if the freeze is executed for 20 seconds, 100 games are determined as the number of games to be added, and if the freeze is executed for 30 seconds, 300 games are determined as the number of games to be added.

Figure 15 also shows the number of entries used in the mode transition lottery when the AT mode ends (see Figure 15 (E)). Here, in this embodiment, the number of entries corresponding to the reset mode and the number of entries corresponding to the pull-back mode are specified for each setting value. Note that in this embodiment, the higher the setting value, the easier it is to transition to the pull-back mode.

<Numbers used in pullback mode>
FIG. 16 illustrates the numbers stored in the main ROM 300 that are used in the pullback mode.

Figure 16 shows the numbers used in the pull-back draw (see Figure 16). In this embodiment, if the result of the role determination is a weak cherry, a strong cherry, a watermelon, a weak chance role, or a strong chance role, the AT mode pull-back draw is performed, and if the pull-back draw is won, the game will return to the AT mode.

<Power-on process of main control board 100>
FIG. 18 shows a flow chart of the power-on process for the main control board 100.

In step A1, the main CPU 200 determines whether the power is turned on. Specifically, it determines whether the power button 24 is operated and the power switch 24A is turned on.

In step A2, the main CPU 200 performs a setting value change process. Specifically, when the keyhole switch 22A detects that the setting key has been inserted into the keyhole and rotated a predetermined angle, the current setting value is displayed on the setting value display unit 23. When the setting value change button 21 is operated and the setting value change switch 21A is turned on, the setting value displayed on the setting value display unit 23 is updated. When the start switch 5A detects the operation of the start lever 5, the setting value is confirmed, and the confirmed setting value is stored in the setting value memory area 401.

In step A3, the main CPU 200 performs game progress control processing. The game progress control processing will be explained with reference to FIG. 19.

<Game Progress Control Processing of the Main Control Board 100>

In step Z4, the main CPU 200 determines whether the value of the advantageous zone number counter 415 is equal to or greater than 2401. The value of the advantageous zone number counter 415 is set to count the number of medals that have been paid out in BB mode, AT mode, etc.

<Timer interrupt processing>
44 shows a flowchart of the timer interrupt process of the main control board 100. The timer interrupt process is a process that interrupts the game progress control process of the main control board 100 every 1 ms.

In step AA1, the main CPU 200 performs interrupt initialization processing. Specifically, it saves registers and disables interrupts.

In step AA2, the main CPU 200 determines whether a power outage has been detected.

In step AA3, the main CPU 200 performs power-off processing. Specifically, it performs processing to save the registers and to save the stack pointer and interrupt state. It also performs processing to retain the information stored in the game status memory area 402 and the information stored in the condition device memory area 403. It then performs processing to calculate a checksum and to store the checksum.

In step AA4, the main CPU 200 updates the value of the interrupt counter. Specifically, the interrupt counter is decremented by 1.

In step AA5, the main CPU 200 performs timer measurement processing. This processing subtracts 1 from the values of the freeze timer 411, wait timer 412, etc.

In step AA6, the main CPU 200 performs input port reading processing. Specifically, it reads, stores, and determines the signal levels of various signals input to the input ports.

In step AA7, the main CPU 200 performs reel control processing. Specifically, it controls the drive of the left reel 6, center reel 7, and right reel 8 (accelerating, decelerating, maintaining a constant speed, or stopping the rotation of the left reel 6, center reel 7, and right reel 8, etc.). In addition, depending on the drive state of the left reel 6, center reel 7, and right reel 8 (stopped, waiting for reel rotation, accelerating, at a constant speed, decelerating), it updates the drive pulse output counter value, which indicates the timing to switch the excitation layer of the stepping motor, and acquires, updates, and outputs reel drive pulse data that drives the stepping motor.

In step AA8, the main CPU 200 determines whether the reel control process of step AA7 has been performed on all of the left reel 6, center reel 7, and right reel 8.

In step AA9, the main CPU 200 performs port output processing. Specifically, excitation output is performed on the left reel 6, center reel 7, right reel 8, hopper 20, etc.

In step AA10, the main CPU 200 performs a command transmission process. Specifically, a process of transmitting the control commands stored in the control command buffer is performed. Here, the control commands stored in the control command buffer are explained. After the values in each area of the main RAM 400 are updated, the control commands are stored in the control command buffer. Examples of the control commands include a role determination command having information on the role determination result by the role determination process in step B3, an instruction information command having information on the determined instruction information, a stop command having information on the stopped reels, and a win command having information on the winning symbol combination.

In step AA11, the main CPU 200 outputs an outer end signal. Specifically, the outer end signal data is read, and the outer end signal is output to the outside of the slot machine 1.

In step AA12, the main CPU 200 performs LED display processing. Specifically, it controls the lighting and extinguishing of the reserve display section 13, payout display section 14, bet number display section 15, replay display section 16, start permission display section 17, deposit permission display section 18, and advantageous zone display section 19.

For example, when no error has occurred, the payout display unit 14 performs a process of displaying the number of medals paid out, a process of displaying a setting value, and a process of displaying instruction information. In addition, when an error has occurred, the payout display unit 14 performs a process of displaying information about the error.

In step AA13, the main CPU 200 performs error management processing. Specifically, processing is performed to determine whether an error has occurred. Furthermore, if an error has occurred, processing is performed to send error information to the sub-control board 800.

In step AA14, the main CPU 200 performs a random number update process. This process updates the random number value used to determine the winning combination.

In step AA15, the main CPU 200 performs interrupt return processing. Specifically, it performs processing to return registers and to permit interrupts.

<Power-on process for the sub-control board 800>
FIG. 45 shows a flowchart of the power-on process for the sub-control board 800.

In step AB1, the secondary CPU 811 determines whether the power is turned on. Specifically, it determines whether the power button 24 is operated and the power switch 24A is turned on.

In step AB2, the secondary CPU 811 performs main control board communication processing. Specifically, it determines whether a command has been received from the main control board 100. If a command has been received from the main control board 100, a process of storing the command in the secondary RAM 813 is performed.

In step AB3, the secondary CPU 811 performs image display device control processing. Specifically, the image display device 26 is controlled via the sound image CPU 821.

In step AB4, the secondary CPU 811 performs lamp control processing. Specifically, it controls the lamp 25.

In step AB5, the secondary CPU 811 performs speaker control processing. Specifically, the speaker 27 is controlled via the sound image CPU 821.

In step AB6, the secondary CPU 811 performs various switch detection processes. Specifically, when the performance switch 28A detects the operation of the performance button 28, a process is performed to switch the image displayed on the image display device 26, when the light adjustment switch 29A detects the operation of the light adjustment button 29, a process is performed to adjust the light intensity of the lamp 25, and when the sound adjustment switch 30A detects the operation of the sound adjustment button 30, a process is performed to adjust the volume of the speaker 27.

<Animation in direct hit mode>
FIG. 46 shows the animation in direct hit mode.

Figure 46 (A) shows the state of the image display device 26 when in the reset mode. Specifically, a daytime image is displayed on the image display device 26. This indicates that the reset mode is in effect.

Figure 46 (B) illustrates the state of the image display device 26 when in normal mode. Specifically, a daytime image is displayed on the image display device 26. This indicates that the mode is normal.

Figure 46 (C) illustrates the state of the image display device 26 when in normal mode or when in direct hit mode. Specifically, an evening image different from the daytime image is displayed on the image display device 26. This indicates that the direct hit mode is in effect.

Figure 46 (D) shows the state of the image display device 26 when in direct hit mode. Specifically, a night image different from the daytime image and the evening image is displayed on the image display device 26. This notifies the user that the device is in direct hit mode.

In this embodiment, if a daytime image is displayed on the image display device 26, it is highly likely that the device is in reset mode or normal mode. However, even if the device is in direct hit mode, a daytime image can be displayed on the image display device 26.

In addition, in this embodiment, when an evening image is displayed on the image display device 26, there is a higher possibility that the vehicle will be in direct hit mode than when a daytime image is displayed.

In addition, in this embodiment, if a night image is displayed on the image display device 26, it means that the device is in direct hit mode. In other words, if the device is not in direct hit mode, the device is configured so that the night image is not displayed on the image display device 26.

<Freeze animation>
FIG. 47 shows the animation when frozen.

In FIG. 47, in the AT mode, the role determination process in step B3 determines that the role is a weak cherry, the additional lottery process in step L2 determines the number of additional games to be 10, the freeze setting process in step X7 determines a 6-second freeze, and the number of additional games due to the freeze is 20.

Figure 47 (A) shows the state of the image display device 26 when in AT mode. Specifically, it shows the state of the image display device 26 when the start lever 5 is operated and the left reel 6, center reel 7, and right reel 8 start to rotate. At this time, the image display device 26 displays a cherry symbol 1006. In other words, the image display device 26 notifies the user that the determined winning combination is a cherry.

As shown in FIG. 47(A), the display area of the image display device 26 is provided with a remaining game number display area 1100 that displays the number of games that can be played in AT mode, and an acquired medal number display area 1200 that displays the number of acquired medals.

Figure 47 (B) shows the state of the image display device 26 when the left stop button 9, center stop button 10, and right stop button 11 are operated after the state of Figure 47 (A), causing the left reel 6, center reel 7, and right reel 8 to stop spinning. Specifically, the number of games determined by the additional lottery process of step L2 is displayed on the image display device 26. Note that Figure 47 (B) indicates that the number of additional games is 10.

In addition, after 10 games are announced as the added number of games, the value in the remaining game number display area 1100 is updated. Specifically, in FIG. 47(B), the value in the remaining game number display area 1100 is updated from 20 games to 30 games.

Figure 47 (C) shows the state when the start lever 5 is operated after the state of Figure 47 (B) and freezing is performed. Here, Figure 47 (C) shows the state from when freezing begins until 5 seconds have elapsed. Here, in this embodiment, the display mode of the image display device 26 during freezing is the same as the image display mode of the image display device 26 in AT mode, but the display mode of the image display device 26 during freezing may be a display mode different from the image display mode of the image display device 26 in AT mode.

Figure 47 (D) shows the state after the state of Figure 47 (C). Here, Figure 47 (D) shows the state from 5 seconds after the freeze started until 6 seconds have passed, and the image display device 26 displays that the number of added games is 20.

Figure 47 (E) shows the state after the state of Figure 47 (D). Here, Figure 47 (E) shows the state from 5 seconds after the freeze to 6 seconds after the freeze, and the image display device 26 displays that the number of games added by the freeze is 20 games.

In this embodiment, as explained in the flow from Figure 47 (C) to Figure 47 (D), the last second of the time during which the freeze is being executed is the notification time for notifying the number of added games.

Figure 47 (F) shows the state of the image display device 26 when the left reel 6, center reel 7, and right reel 8 start to rotate after Figure 47 (E). Here, in Figure 47 (F), the role determination process of step B3 determines that the role is the push order bell BA, and the image display device 26 notifies the yellow bell pattern 1004 and the operation order of the left stop button 9, center stop button 10, and right stop button 11.

<Animation to indicate freezing/notification in AT mode>
FIG. 48 shows an animation of freeze indication/notification in the AT mode.

In FIG. 48(A), when the role determination process in step B3 determines that the role is a rare role, an AT daytime image that does not suggest the possibility of freezing is displayed on the image display device 26. Note that when the role determination process in step B3 determines that the role is a rare role, the AT daytime image can be displayed in cases where freezing is or is not performed based on the scenario stored in the scenario memory area 425.

In FIG. 48(B), when the role determination process in step B3 determines that the role is a rare role, an evening image during the AT, suggesting the possibility of a freeze being performed, is displayed on the image display device 26. Here, when an evening image during the AT is displayed on the image display device 26, it suggests that there is a higher possibility of a freeze being performed compared to when an AT daytime image is displayed on the image display device 26. Note that when the role determination result is a rare role, the evening image during the AT can be displayed in cases where a freeze is performed or where a freeze is not performed based on the scenario stored in the scenario memory area 425.

In FIG. 48 (C), an AT night image is displayed on the image display device 26 to notify that freezing will occur if the role determination process in step B3 determines that the role is a rare role. Here, when the AT night image is displayed on the image display device 26, it notifies that freezing will occur if the role determination result is a rare role. Note that the AT evening image is displayed only when freezing is executed based on the scenario stored in the scenario memory area 425 when the role determination result is a rare role, and is not displayed if freezing is not executed.

In FIG. 48, it is described that when the next role is determined to be a rare role, a suggestion or notification is given as to whether or not a freeze will occur. However, it is also possible to suggest or notify multiple times, for example, by providing information on the next role and the role after that. Also, when a scenario is determined, information on the scenario itself may be suggested or notified.

<Animation from retraction mode to return to AT mode>
FIG. 49 shows an animation from the pull-back mode to the return to the AT mode.

In FIG. 49(A), an image notifying the end of the AT mode is displayed on the image display device 26. At this time, the image display device 26 displays a text image saying "AT End" and the number of medals paid out in the AT mode.

In FIG. 49(B), an image notifying the user of the pull-back mode is displayed on the image display device 26. Specifically, a pull-back expectation display area 1300 is provided in the display area of the image display device 26, and the expectation of returning to the AT mode is displayed in this pull-back expectation display area 1300.

In FIG. 49(C), the expectation displayed in the pull-back expectation display area 1300 has been updated. Specifically, the pull-back expectation display area 1300 of the image display device 26 indicates that the expectation is 3.

In FIG. 49 (D), when the value of the pullback game number counter reaches 3, a continuous performance is displayed on the image display device 26.

In FIG. 49(E), after FIG. 49(D), when the value of the pullback game number counter becomes 0, the result of the continuous performance is displayed on the image display device 26. Specifically, in FIG. 49(E), an image announcing a return to the AT mode is displayed on the image display device 26.

In FIG. 49(F), after FIG. 49(E), when the start lever 5 is operated, an image corresponding to the AT mode is displayed on the image display device 26.

<Animation from pull back mode to reset mode>
FIG. 50 shows an animation of the transition from the pull back mode to the reset mode.

In FIG. 50(A), an image notifying the end of the AT mode is displayed on the image display device 26. At this time, the image display device 26 displays a text image saying "AT End" and the number of medals paid out in the AT mode.

In FIG. 50(B), an image notifying the user of the pull-back mode is displayed on the image display device 26. At this time, the expectation level is displayed in the pull-back expectation level display area 1300 of the image display device 26, similar to FIG. 49(B).

In FIG. 50(C), the expectation level is updated and displayed. Specifically, the pullback expectation level display area 1300 of the image display device 26 indicates that the expectation level is 3.

In FIG. 50 (D), when the value of the pullback game number counter reaches 3, a continuous performance is displayed on the image display device 26.

In FIG. 50(E), after FIG. 50(D), when the value of the pullback game number counter becomes 0, the result of the continuous performance is displayed on the image display device 26. Specifically, in FIG. 50(E), an image is displayed on the image display device 26 notifying the user of a transition to the reset mode.

Figure 50 (F) shows the state after Figure 50 (E) when the start lever 5 is operated. At this time, a daytime image suggesting the reset mode is displayed on the image display device 26.

<Animation when it is announced that the device will return to AT mode>
FIG. 51 shows an animation that appears when a return to the AT mode is notified.

In FIG. 51(A), an image notifying the end of the AT mode is displayed on the image display device 26. At this time, the image display device 26 displays a text image saying "AT End" and the number of medals paid out in the AT mode.

In FIG. 51(B), an image notifying the user of the pull-back mode is displayed on the image display device 26. At this time, the expectation level is displayed in the pull-back expectation level display area 1300 of the image display device 26, similar to FIG. 49(B) and FIG. 50(B).

In FIG. 51(C), the expected return rate is updated and displayed. Specifically, the expected return rate display area 1300 of the image display device 26 indicates that the expected return rate is 5. In other words, a transition to the AT mode is indicated.

In this embodiment, when the expectation level display area 1300 indicates that the expectation level is 5, no continuous performance will be performed even if the value of the number of pull-back games counter 424 becomes 3.

In FIG. 51(D), when the value of the pull-back game number counter 424 becomes 0, an image notifying the AT mode and the like are displayed on the image display device 26. In other words, when the pull-back expectation display area 1300 notifies that the expectation level is 5, the image display device 26 will transition to the AT mode without displaying a continuous performance.

<Animation when the expected return rate is 0>
FIG. 52 shows an animation when the pullback expectation is 0.

In FIG. 52(A), an image notifying the end of the AT mode is displayed on the image display device 26. At this time, the image display device 26 displays a text image saying "AT End" and the number of medals paid out in the AT mode.

In FIG. 52(B), an image notifying the user of the pull-back mode is displayed on the image display device 26. Here, when the value of the pull-back game number counter 424 reaches 3, if the expectation displayed in the pull-back expectation display area 1300 remains at 0, the continuous performance is not executed.

In FIG. 52(C), when the value of the pullback game number counter 424 reaches 0, a daytime image suggesting the reset mode is displayed on the image display device 26.

<Number of effects placed when the draw is won>
FIG. 53 shows the number of effects placed when a redraw lottery is won.

The number of effects placed when the pull-back lottery is won is stored in the sub-ROM 812, and is used to determine the value to be added to the expectation value (hereinafter referred to as the "expected value") displayed in the pull-back expectation display area 1300 when the pull-back lottery is won. Specifically, the number of effects placed when the pull-back lottery is won is set to a number that corresponds to the expected value added for each winning combination.

In this embodiment, when the expected value is 0, the value to be added to the expected value is determined by referring to the number of effects placed at the time of the winning draw shown in FIG. 53 (A) (expected value = 0). For example, when the expected value is 0 and the result of the role determination is a weak cherry, there is a 10,000/65536 probability that the expected value will not be added, there is a 30,000/65536 probability that 1 will be added to the expected value, there is a 20,000/65536 probability that 2 will be added to the expected value, there is a 5,000/65536 probability that 3 will be added to the expected value, there is a 500/65536 probability that 4 will be added to the expected value, and there is a 36/65536 probability that 5 will be added to the expected value.

In addition, when the expected value is 1, the value to be added to the expected value is determined by referring to the number of effects placed at the time of the winning pull-back lottery (expected value = 1) shown in FIG. 53 (B). For example, when the expected value is 1 and the result of the role determination is a weak cherry, there is a 20,000/65536 probability that the expected value will not be added, a 30,000/65536 probability that 1 will be added to the expected value, a 10,000/65536 probability that 2 will be added to the expected value, a 5,000/65536 probability that 3 will be added to the expected value, and a 536/65536 probability that 4 will be added to the expected value.

In addition, when the expected value is 2, the value to be added to the expected value is determined by referring to the number of effects placed at the time of the winning pull-back lottery (expected value = 2) shown in Figure 53 (C). For example, when the expected value is 2 and the result of the role determination is a weak cherry, there is a 20,000/65,536 probability that the expected value will not be added, a 30,000/65,536 probability that 1 will be added to the expected value, a 15,000/65,536 probability that 2 will be added to the expected value, and a 536/65,536 probability that 3 will be added to the expected value.

In addition, when the expected value is 3, the value to be added to the expected value is determined by referring to the number of effects placed at the time of the winning pull-back lottery (expected value = 3) shown in Figure 53 (D). For example, when the expected value is 3 and the result of the role determination is a weak cherry, there is a 20,000/65,536 probability that the expected value will not be added, a 40,000/65,536 probability that 1 will be added to the expected value, and a 5,536/65,536 probability that 2 will be added to the expected value.

In addition, when the expected value is 4, the value to be added to the expected value is determined by referring to the number of effects placed at the time of the winning pull-back lottery (expected value = 4) shown in Figure 53 (E). For example, when the expected value is 4 and the result of the combination determination is a weak cherry, there is a 60,000/65,536 probability that the expected value will not be added, and a 5,536/65,536 probability that 1 will be added to the expected value.

When the expected value is 5, the expected value is not increased. This is because the maximum expected value is 5. In other words, when the expected value is 5, a notification is issued that the mode will change to AT mode.

In addition, in this embodiment, if the result of the role determination is a strong chance role while in the pull-back mode, the expected value is increased to the maximum value of 5. This is because, as explained in the setting number used in the pull-back lottery (see Figure 16), if the result of the role determination is a strong chance role while in the pull-back mode, the mode will transition to AT mode.

<Number of effects placed when the pull-back lottery is not won>
FIG. 54 shows the number of effects placed when the pull-back lottery is not won.

The number of effects placed when the pull-back lottery is not won is stored in the sub-ROM 812, and is used to determine the value to be added to the expected value when the pull-back lottery is not won. Specifically, the number of effects placed when the pull-back lottery is not won is specified as the number that corresponds to the expected value that is added for each combination.

In this embodiment, when the expected value is 0, the value to be added to the expected value is determined by referring to the number of effects placed when the retraction lottery is not won (expected value = 0) shown in FIG. 54 (A). For example, when the expected value is 0 and the result of the role determination is a weak cherry, there is a 15,000/65536 probability that the expected value will not be added, a 35,000/65536 probability that 1 will be added to the expected value, a 10,000/65536 probability that 2 will be added to the expected value, a 500/65536 probability that 3 will be added to the expected value, and a 36/65536 probability that 4 will be added to the expected value.

In addition, when the expected value is 1, the value to be added to the expected value is determined by referring to the number of effects placed when the pull-back lottery is not won (expected value = 1) shown in FIG. 54 (B). For example, when the expected value is 1 and the result of the role determination is a weak cherry, there is a 25,000/65,536 probability that the expected value will not be added, a 35,000/65,536 probability that 1 will be added to the expected value, a 5,500/65,536 probability that 2 will be added to the expected value, and a 36/65,536 probability that 3 will be added to the expected value.

In addition, when the expected value is 2, the value to be added to the expected value is determined by referring to the number of effects placed when the pull-back lottery is not won (expected value = 2) shown in Figure 54 (C). For example, when the expected value is 2 and the result of the role determination is a weak cherry, there is a 30,000/65,536 probability that the expected value will not be added, a 35,000/65,536 probability that 1 will be added to the expected value, and a 536/65,536 probability that 2 will be added to the expected value.

In addition, when the expected value is 3, the value to be added to the expected value is determined by referring to the number of effects placed when the pull-back lottery is not won (expected value = 3) shown in Figure 54 (D). For example, when the expected value is 3 and the result of the combination determination is a weak cherry, there is a 65,000/65,536 probability that the expected value will not be added, and a 536/65,536 probability that 1 will be added to the expected value.

In addition, when the expected value is 4, the value to be added to the expected value is determined by referring to the number of effects placed when the pull-back lottery is not won (expected value = 4) shown in Figure 54 (E). For example, when the expected value is 4, regardless of the result of the role determination, there is a probability of 65536/65536 that the expected value will not be added.

When the expected value to be added is determined using the number of effects placed when the pull-back lottery is won, the expected value is easier to add compared to when the expected value to be added is determined using the number of effects placed when the pull-back lottery is not won. As a result, the higher the expected value, the higher the anticipation that it has been decided to move to AT mode.

In addition, in this embodiment, when the expected value to be added is determined using the number of effects placed when the pull-back lottery is not won, the added expected value does not become 5. This is to prevent the expected value from becoming 5 even when it has not been decided to transition to AT mode.

<Modification>
The modified example will be described with reference to FIG. 55 and FIG.

<Mode transition diagram in modified example>
FIG. 55 shows a mode transition diagram in the modified example.

As shown in FIG. 55, in the modified example, multiple direct hit modes are provided. Specifically, a first direct hit mode and a second direct hit mode that is more advantageous to the player than the first direct hit mode are provided.

In addition, in the modified example, if transition condition Ea is satisfied while remaining in normal mode, a transition to the first direct hit mode will occur, and if transition condition Eb is satisfied, a transition to the second direct hit mode will occur. Transition condition Ea occurs when, as a result of the direct hit mode transition drawing process of step E8, it is determined to transition to a direct hit drawing and then it is determined to transition to the first direct hit mode. Transition condition Eb occurs when, as a result of the direct hit mode transition drawing process of step E8, it is determined to transition to a direct hit drawing and then it is determined to transition to the second direct hit mode.

Here, the decision as to whether to transition to the first direct hit mode or the second direct hit mode may be made in any manner. For example, a 1/2 lottery may be conducted to determine whether to transition to the first direct hit mode or the second direct hit mode.

In addition, in the modified example, if transition condition M is met while in direct hit mode, the mode will transition from direct hit mode to BB mode. Transition condition M is that the value of the ceiling game number counter 416 has reached 0, as in the above-mentioned embodiment.

In addition, in the modified example, if transition condition N is satisfied while in direct hit mode, the game will transition from the first direct hit mode or the second direct hit mode to the AT mode. As in the above-mentioned embodiment, transition condition N is winning the AT mode transition lottery, but the probability of transitioning to the AT mode is different. This point will be explained using FIG. 56.

In addition, in a modified example, if transition condition Oa is satisfied while in the first direct hit mode, the mode will transition from the first direct hit mode to the normal mode, and if transition condition Ob is satisfied, the mode will transition from the second direct hit mode to the normal mode. The transition condition Oa is that a predetermined number of games have been played while in the first direct hit mode. The transition condition Ob is that a predetermined number of games have been played while in the second direct hit mode. Here, the number of games played in the first direct hit mode and the number of games played in the second direct hit mode may be the same, or the number of games played in the second direct hit mode may be greater.

<Numbers used in the direct hit mode in the modified example>
FIG. 56 shows the numbers used in the direct hit mode in the modified example stored in the main ROM 300.

Figure 56 (A) shows the numbers used in the drawing for the AT mode in the first direct hit mode. Here, in the modified example, the drawing for the AT mode is performed when the result of the role determination is a weak cherry, a strong cherry, a watermelon, a weak chance role, or a strong chance role. Note that in the first direct hit mode, the drawing for the AT mode is performed with the same probability as in the direct hit mode in the above-mentioned embodiment.

Figure 56 (B) shows the numbers used in the drawing for the AT mode in the second direct hit mode. Here, in the modified example, the drawing for the AT mode is performed when the result of the role determination is a weak cherry, a strong cherry, a watermelon, a weak chance role, or a strong chance role.

When in the second direct hit mode, it is easier to transition to AT mode compared to when in the first direct hit mode. Specifically, when in the second direct hit mode, if the result of the role determination is a rare role, the mode will transition to AT mode. Note that, as long as it is easier to transition to AT mode when in the second direct hit mode compared to when in the first direct hit mode, the number of placements can be set appropriately.

In this manner, in the modified example, direct hit modes are provided that are different in degree of advantage to the player. This makes the player want to transition to the second direct hit mode rather than the first direct hit mode while in the normal mode, improving the gameplay of the normal mode. Also, when in the second direct hit mode, the player plays the game with more anticipation for the transition to the AT mode than when in the first direct hit mode, improving the gameplay of the direct hit mode.

In this way, in the present invention, in the normal mode, the BB mode is drawn by the BB drawing process of step E5. Also, in the direct hit mode, the AT mode is drawn by the AT mode drawing process of step J3. As a result, when the player is in the normal mode, a transition to the BB mode is expected, and when the player is in the direct hit mode, a transition to the AT mode is expected, so it is possible to provide a slot machine in which it is easy to know which mode to expect to transition to.

In addition, according to the present invention, an evening image suggesting the direct hit mode and a night image informing the direct hit mode are displayed on the image display device 26, so that when an evening image or a night image is displayed on the image display device 26, the user is expected to be in the direct hit mode.

In addition, according to the present invention, a first direct hit mode and a second direct hit mode that is more advantageous to the player than the first direct hit mode are provided, so the player is expected to transition to the second direct hit mode.

Details of the means described in the above gaming machine will be explained below.

The invention of claim 1 relates to a slot machine equipped with a game control means (e.g., a main control board 100) for controlling the game and a presentation control means (e.g., a sub-control board 800) for controlling the presentation, the game control means comprising a mode control means (e.g., the main control board 100 for performing the mode-specific processing in step B4 and the mode management processing after all stops in step B12) for controlling an unfavorable mode (e.g., a normal mode) that is unfavorable to the player and an advantageous mode (e.g., a BB mode) that is advantageous to the player compared to the unfavorable mode, and a transition drawing means (e.g., the BB drawing in step E5) for performing a transition drawing to the advantageous mode in the unfavorable mode. and a main control board 100 that performs the process of selecting the first advantageous mode in step J1 and the process of selecting the AT mode in step J2. The disadvantageous modes include a normal mode (e.g., normal mode) and a specific mode (e.g., direct hit mode) different from the normal mode. The advantageous modes include a first advantageous mode (e.g., BB mode) and a second advantageous mode (e.g., AT mode) different from the first advantageous mode. The transition drawing means draws a lottery in the normal mode to determine whether or not to transition to the first advantageous mode, and draws a lottery in the specific mode to determine whether or not to transition to the second advantageous mode.

The invention of claim 2 is the slot machine described in claim 1, characterized in that the presentation control means performs control to suggest the specific mode (e.g., display an evening image on the image display device 26) or to notify (e.g., display a night image on the image display device) when the specific mode is being controlled by the mode control means.

The invention of claim 3 is the slot machine described in claim 1 or claim 2, characterized in that the specific modes include a first specific mode (e.g., a first direct hit mode) and a second specific mode (e.g., a second direct hit mode) that is more advantageous to the player than the first specific mode.

Note that the items shown in this embodiment are merely examples and can be modified as appropriate without departing from the scope of the present invention.
