Description

  The present invention relates to a slot machine capable of generating a predetermined winning according to a display result of a variable display device capable of variably displaying a plurality of types of identification information each identifiable.

  A slot machine generally includes a variable display device having a plurality of (usually three) reels on which a plurality of types of symbols as identification information are drawn on the outer periphery, and first, a bet number is determined by a player's BET operation. The reels start to rotate when the start operation is performed with the set number of bets set, and the rotation is stopped by operating a stop button provided corresponding to each reel. When all reels stop rotating, a winning combination occurs when a predetermined winning symbol combination (for example, 7-7-7, hereinafter referred to as a symbol combination) is arranged on the winning line. To do. That is, the game is advanced by the player's operation.

  In this type of slot machine, after the start operation, after the reels have been rotated at a constant speed, the stop button is activated. Change the rotation mode so that the symbols constituting the winning combination are aligned in a straight line, rotate the reel at a low speed in that state, and then make the state where the symbols are lined up visible, then shift to constant speed rotation A slot machine has been proposed (see Patent Document 1).

JP 2010-29493 A

  However, in the slot machine as described in Patent Document 1, the symbols constituting the winning combination of each reel are controlled so as to be aligned in a straight line before the stop button becomes effective, and the state can be visually recognized. Although it becomes possible to produce an impact with the rotation mode of the reel, it shifts to constant speed rotation with the symbols still aligned, and the stop button becomes effective, so the winning combination The level of difficulty in the operation of the stop button when aligning the winning combination varies depending on whether the constituent symbols are controlled to be in a straight line or when such control is performed. There is a risk of harm.

  The present invention has been made paying attention to such problems, and an object of the present invention is to provide a slot machine that can ensure the fairness of the game even if the presentation is performed in the variation mode of the variable display section. And

In order to solve the above problems, the slot machine of the means 1 of the present invention comprises:
A plurality of variable display portions that can be variably displayed by moving display bands (reels 2L, 2C, 2R) in which a plurality of types of symbols that can be identified are arranged in a predetermined order are provided,
A game can be started by setting a predetermined number of bets for one game using the gaming value, and one game is ended by deriving display results on all of the plurality of variable display portions. A slot machine (slot machine) in which a winning can be generated according to a combination of display results derived to the plurality of variable display units,
Pre-determining means (internal lottery) for determining whether or not to allow a prize to be generated before a display result is derived to the plurality of variable display units;
Derivation operation means (stop switches 8L, 8C, 8R) each operated when deriving a display result from the plurality of variable display units;
Derivation operation enabling means for activating the operation of the derivation operation means (stop switches 8L, 8C, 8R) after the start of the game;
Derivation control means (reel stop control) for controlling the variable display unit corresponding to the derivation operation means to derive a display result based on the determination result of the predetermination means when the derivation operation means is operated When,
Validation delay means (freeze control) for delaying validation of the operation of the derivation manipulation means by the derivation manipulation validation means;
After the start of the game, during the period (freeze period) in which the activation delay means delays the activation of the operation of the derivation operation means, the display bands (reels 2L, 2C, 2R) Fluctuation control for performing fluctuation control (reel effect control) of the plurality of variable display units so that the relative positional relationship between the two becomes a specific positional relationship (for example, a positional relationship in which “black 7” is aligned on a straight line). Means,
Derived positional relationship that is the relative positional relationship between the display bands (reels 2L, 2C, 2R) when the display result is finally derived by the derivation control means (the positional relationship between the reels when the reels are stopped) A positional relationship specifying means for derivation that specifies an initial positional relationship)
After the variation control means controls the relative positional relationship between the display bands to be the specific positional relationship, the relative positional relationship between the display bands is determined as the derived positional relationship (when the reel is stopped). Positional relationship control means for performing a control (temporary stop at the stop position when the reel is stopped) indicating that the positional relationship has been returned to
With
The derivation operation validating means is configured such that the relative positional relationship between the display bands is determined by the variation control means in a period (freeze period) in which the validation delay means delays the validation of the manipulation of the derivation manipulation means. After being controlled to be in the specific positional relationship, the relative positional relationship between the display bands is returned to the derived positional relationship (initial positional relationship) by the derived positional relationship control means, and the derived positional relationship After the control indicating the return to the position (pause at the stop position when the reel is stopped) is performed, the operation of the derivation operation means (stop switches 8L, 8C, 8R) is validated. .
According to this feature, the relative positional relationship between the display bands constituting the plurality of variable display units becomes the specific positional relationship during the period in which the activation of the operation of the derivation operation unit is delayed after the game is started. Thus, the control of the plurality of variable display units is performed, so that it is possible to produce an impact effect in the display mode of the variable display unit, and the positional relationship between the display bands when finally derived to the plurality of variable display units After the position relation at the time of derivation is specified and the control to obtain the specific position relation is made, before the derivation operation means becomes effective, the relative positional relation between the display bands is returned to the position relation at the time of derivation. Whether the control is performed or not, the difficulty of the operation by the derivation operation means does not change, and the fairness of the game is ensured even when the control is performed in a specific positional relationship. Can do. In addition, after the control for setting the specific positional relationship, not only the positional relationship at the time of derivation is returned, but also after the control that suggests that the positional relationship at the time of derivation has been returned, the operation of the derivation operation means is validated. It is possible to inform the player that the positional relationship has been returned to the derivation positional relationship instead of maintaining the relationship, and it is possible to prevent the operation of the derivation operation means from being mistaken for the specific positional relationship.

The slot machine according to means 2 of the present invention is the slot machine according to means 1,
Visibility changing means for changing the visibility (lighting mode of the reel LED 55) of the variable display section during a period (freeze period) in which the validation delay means delays validation of the operation of the derivation operation means. It is characterized by.
According to this feature, the visibility of the variable display unit is changed during a period in which the activation of the operation of the derivation operation unit is delayed. Therefore, without changing the difficulty level of the operation by the derivation operation unit, It is possible to produce effects by changing the visibility.
Note that the visibility of the variable display unit may be changed as long as the appearance of the variable display unit is different from that before the change.For example, the brightness of the variable display unit is changed, and the saturation of the variable display unit is changed. It may be anything such as changing, changing the hue of the variable display section, or changing the size of the area where the variable display section can be seen. More specifically, the brightness may be changed from a bright state to a dark state, or from a dark state to a bright state. Moreover, as a case where the saturation of the variable display unit is changed, the variable display unit may be changed from a clear state to an unclear state, or may be changed from an unclear state to a clear state. Further, as a case where the hue of the variable display portion is changed, the base color may be changed from blue to blue. In addition, as a case where the area of the variable display portion visible is changed, it may be narrowed by physically blocking a part or all of the variable display portion.
Further, the visibility changing unit may be any device that changes the visibility of the variable display unit as in the above example, and the visibility of the variable display unit is a direct function of the visibility changing unit itself. Even if it changes the visibility, the visibility of the variable display section may be changed indirectly by the action of the visibility changing means itself. As the visibility changing means for indirectly changing the visibility of the variable display section, for example, a light emitting means such as a reel LED / lamp that emits light from the back side or the front side to the display band constituting the variable display section. Further, when the variable display unit is configured by an image display such as a liquid crystal display, a backlight that irradiates light to the display screen of the image display may be used. For example, in the case of a reel LED, it can be said that the visibility of the variable display unit is indirectly changed by changing the light irradiation mode on the reel. The visibility changing means for directly changing the visibility of the variable display unit is, for example, an image display such as a transmissive liquid crystal display arranged on the front side of the display band constituting the variable display unit. There may be. In this case, the visibility of the variable display unit can be directly changed by executing a predetermined effect (image display or the like) on the image display.

To control automatically or indirectly.

  Similar to the main CPU 41a, the sub CPU 91a has an interrupt function (including an interrupt prohibition function). One of the interrupt terminals of the sub control unit 91 is connected to a strobe (INT) signal line that is output when the main control unit 41 transmits a command, among the command transmission lines, and the sub CPU 91a receives the strobe signal. An interrupt is generated based on the input to acquire a command from the main control unit 41 and execute a command reception interrupt process to be stored in the buffer. Further, the sub CPU 91a executes an interrupt process (sub) to be described later by generating an interrupt every time the number of clock inputs reaches a certain number, that is, every certain interval. One of the interrupt terminals of the sub-control unit 91 is connected to the power interruption detection circuit 98, and the sub CPU 91a responds to the input of the voltage drop signal output from the power interruption detection circuit 98. Execute processing (sub). Further, when an unused interrupt occurs in the sub CPU 91a, an unused interrupt process for immediately returning to the original process is executed.

  The sub-control unit 91 is also supplied with backup power at the time of a power failure, and the data stored in the RAM 91c is held while the backup power is supplied.

  In the slot machine 1 of the present embodiment, the medal payout rate changes according to the set value. Specifically, the medal payout rate is changed by using a winning probability corresponding to a set value in an internal lottery described later. The set value is composed of 6 levels of 1 to 6, with 6 being the highest payout rate and the payout rate being lower as the value is decreased in the order of 5, 4, 3, 2, 1. That is, when 6 is set as the set value, the advantage is highest for the player, and as the value decreases in order of 5, 4, 3, 2, 1, the advantage decreases stepwise.

  In order to change the setting value, it is necessary to turn on the power of the slot machine 1 after the setting key switch 37 is turned on. When the setting key switch 37 is turned on and the power is turned on, the setting value read from the RAM 41c is displayed on the setting value display 24 as a display value, and the setting value can be changed by operating the reset / setting switch 38. Transition to the setting change state. When the reset / setting switch 38 is operated in the setting change state, the display value displayed on the setting value display 24 is updated one by one (when further operation is performed from the setting 6, the display returns to the setting 1). . When the start switch 7 is operated, the display value is determined as the set value. Then, when the setting key switch 37 is turned OFF, the determined display value (setting value) is stored in the RAM 41c of the main control unit 41, and the state shifts to a state in which the game can proceed.

  In order to confirm the set value, after the game is over, the setting key switch 37 may be turned on with no bet amount set. When the setting key switch 37 is turned on in such a situation, the setting value read out from the RAM 41c is displayed on the setting value display 24, thereby shifting to a setting confirmation state in which the setting value can be confirmed. In the setting confirmation state, the game cannot be progressed, and by turning the setting key switch 37 to the OFF state, the setting confirmation state is ended and the state in which the game can proceed is returned.

  In the slot machine 1 of the present embodiment, when the main CPU 41a detects a voltage drop signal from the power interruption detection circuit 48, a power interruption interrupt process (main) is executed. In the power interruption interrupt processing (main), the register is saved in a stack of a RAM 41c, which will be described later, and data for destructive diagnosis (in this embodiment, 5AH) in which any bit is 1 in the RAM 41c, that is, a specific value other than 0 In addition to storing data, the RAM parity adjustment data is calculated so that the RAM parity based on the data stored in all areas of the RAM 41c is 0, and the RAM 41c is stored. The RAM parity is a value calculated as an exclusive OR of values stored in each bit of the corresponding area (all areas in this embodiment) of the RAM 41c. Therefore, if the RAM parity based on the data stored in all areas of the RAM 41c is 0, the RAM parity adjustment data is 0, and the RAM parity based on the data stored in all areas of the RAM 41c is 1. In this case, the RAM parity adjustment data is 1.

  The main CPU 41a calculates the RAM parity based on the data stored in all areas of the RAM 41c at the time of activation, confirms the value of the destructive diagnosis data, the RAM parity is 0, and the destructive diagnosis The processing state of the main CPU 41a is restored to the state before the power interruption based on the data stored in the RAM 41c on the condition that the value of the data for use is correct, but the RAM parity is not 0 (in the case of 1) or is destroyed. If the value of the diagnostic data is not correct, it is determined that the RAM is abnormal, and the RAM abnormal error code is set in the register to control the RAM abnormal error state so that the progress of the game is disabled. Unlike the other error states, the RAM abnormal error state is not canceled even if the reset switch 23 or the reset / setting switch 38 is operated, and a new set value is set in the setting change state described above. It will not be released until

  In this embodiment, all the data stored in the RAM 41c is held by the backup power source even in the event of a power failure, and when the main CPU 41a determines that the data in the RAM 41c is normal when the power is turned on. Although the configuration is such that the control state before power interruption is restored based on the data stored in the RAM 41c, only the data necessary for the restoration of the control state in the event of a power failure is backed up among the data stored in the RAM 41c. It may be configured to return to the control state before power interruption based on the backed up data.

  In addition, when returning to the control state before the power interruption when the power is turned on, it is not necessary to return all the control states to the control state before the power interruption, and the minimum control state that does not disadvantage the player For example, it is not necessary to restore the state of all input ports to the state before power interruption.

  In addition, when the sub CPU 91a detects the voltage drop signal from the power interruption detection circuit 98, the sub CPU 91a also executes a power interruption interrupt process (sub). In the power interruption interrupt processing (sub), the register is saved in a stack of a RAM 91c described later, and destructive diagnosis data in which any bit is 1 is stored in the RAM 91c, and data stored in all areas of the RAM 91c. The RAM parity adjustment data is calculated so that the RAM parity based on 0 becomes 0 and stored in the RAM 91c.

  Then, the sub CPU 91a calculates the RAM parity based on the data stored in all areas of the RAM 91c at the time of activation, and based on the data stored in the RAM 91c on the condition that the RAM parity is 0. The processing state of the sub CPU 91a is restored to the state before the power interruption. If the RAM parity is not 0 (1), it is determined that the RAM is abnormal and the RAM 91c is initialized. In this case, unlike the sub CPU 91a, the execution of the performance is not disabled only by initializing the RAM 91c.

  In this embodiment, all data stored in the RAM 91c is held by the backup power source even during a power failure, and the sub CPU 91a determines that the data in the RAM 91c is normal when the power is turned on. Although the configuration is such that the control state before power interruption is restored based on the data stored in the RAM 91c, only the data necessary for restoration of the control state is backed up in the event of a power failure out of the data stored in the RAM 91c. It may be configured to return to the control state before power interruption based on the backed up data.

  In addition, when returning to the control state before the power interruption when the power is turned on, it is not necessary to return all the control states to the control state before the power interruption, and the minimum control state that does not disadvantage the player It is not necessary to restore the state of the input port or the progress in the middle of the production when it is interrupted. For example, while backing up only data indicating the gaming state such as whether it is in the BB or the normal gaming state, other than the effect corresponding to the gaming state (the effect during the BB during the BB, the normal effect when in the normal gaming state) If a power outage occurs during the execution of a specific production (such as a small role announcement), it will be backed up when the power is turned on instead of resuming the specific production that was being performed at the next power-on. An effect corresponding to the gaming state being played may be executed from the beginning.

  Next, initialization of the RAM 41c of the main control unit 41 will be described. The storage area of the RAM 41c of the main control unit 41 is divided into an important work, a general work, a special work, a set value work, a stop phase work, a non-saved work, an unused area, and a stack area.

  The important work is a work in which data that is inconvenient to be initialized at the end of the BB, such as various display devices and LED display data, input / output data of the I / O port 41d, and a game time clock counter, is stored. The general work is a work that stores data that can be initialized at the end of the BB, such as a stop control table, a stop symbol, the number of medals paid out, and the total number of medals paid out in the BB. The special work is a work that stores data to be initialized only before the start of setting, such as data for transmitting a command to the effect control board 90 and various software random numbers. The set value work is a work in which a set value used when performing a lottery in the internal lottery process is stored. After initializing 0 before setting is started (before shifting to the setting change mode), 1 is stored. The set value that is corrected and newly set at the end of the setting (when the setting change mode is ended) is stored. The stop phase work is a work in which data indicating the stop phase of the reel motors 32L, 32C, 32R is stored, and data indicating the stop phase is stored when the reel motors 32L, 32C, 32R are stopped. The Rukoto. The unsaved work is a work that holds the state of various switches, and a value is always set regardless of whether or not the data in the RAM 41c is destroyed at the time of activation. The unused area is an unused area in the storage area of the RAM 41c, and is initialized if any one of a plurality of initialization conditions described later is satisfied. The stack area is an area in which data saved from the register of the main CPU 41a is stored, and the unused stack area is established by any one of a plurality of initialization conditions to be described later, like the unused area. In this case, the used stack area is not initialized because the program continues.

  In this embodiment, the main CPU 41a operates when the setting key switch 37 and the reset / setting switch 38 are both ON, when a RAM error occurs, when starting only when the setting key switch 37 is ON, BB At the end, when the setting key switch 37 and the reset / setting switch 38 are both OFF, when the data in the RAM 41c is not destroyed, the six initialization conditions at the end of one game are satisfied In addition, five types of initialization are performed in different regions to be initialized according to each initialization condition.

  Initialization 0 is performed when the setting key switch 37 and the reset / setting switch 38 are both ON at the time of start-up, and initialization is performed before the transition to the setting change mode or when a RAM abnormality error occurs. In initialization 0, all areas (including the unused area and the unused stack area) of the storage area of the RAM 41c other than the used stack area are initialized. Initialization 1 is an initialization performed only when the setting key switch 37 is in an ON state at the time of start-up and shifts to the setting change mode. In the initialization 1, in the storage area of the RAM 41c, All areas (including the unused area and the unused stack area) other than the in-use stack area and the stop phase work are initialized. Initialization 2 is initialization performed at the end of the BB. In initialization 2, the general work, the unused area, and the unused stack area are initialized in the storage area of the RAM 41c. Initialization 3 is an initialization performed when both the setting key switch 37 and the reset / setting switch 38 are in an OFF state at the time of activation, and the data in the RAM 41c is not destroyed. The stored work, unused area, and unused stack area are initialized. Initialization 4 is initialization performed at the end of one game. In initialization 4, an unused area and an unused stack area in the storage area of the RAM 41c are initialized.

  In this embodiment, initialization 0 and initialization 1 are performed before transition to the setting change mode. However, they may be performed at the end of the setting change mode, that is, after the setting is confirmed. In this case, if the set value work is initialized, the determined set value is lost. Therefore, the set value work is not initialized.

  In the slot machine 1 according to the present embodiment, the prescribed number of bets that can be set according to the gaming state is determined as described above, and the prescribed number of bets that are determined according to the gaming state is set. It becomes possible to start the game on the condition. In the present embodiment, as will be described later, there are a regular bonus (hereinafter referred to as RB) and a normal gaming state as a gaming state, and 3 is defined as the prescribed number of bets in any gaming state. Regardless of the gaming state, when 3 is set as the bet number, the game can be started. In the present embodiment, all of the pay lines L1 to L5 are activated when a specified number of bets corresponding to the gaming state are set.

  In the slot machine 1 of this embodiment, when all the reels 2L, 2C, 2R are stopped, a winning combination is obtained when a combination of symbols called “comb” is arranged on the activated winning line (hereinafter simply referred to as a winning line). It becomes. The combination may be a combination of the same symbols or a combination including different symbols. The type of winning combination is determined according to the game state, but it can be roughly divided into a small role with payout of medals and a replay that can start the next game without the need to set the number of bets. There are a game combination and a special combination with a transition of the game state. Below, a small role and a re-playing role are collectively called a general role. In order for winning of each combination determined according to the gaming state to occur, it is necessary to win an internal lottery to be described later and set a winning flag of the combination in the RAM 41c.

  Of the winning flags for each of these combinations, the winning flag for the small role and the re-playing role is valid only in the game in which the flag is set, and is invalid in the next game. It is valid until a combination of combinations permitted by the flag is completed, and is invalid in a game having a combination of combinations permitted. In other words, once the special combination winning flag is won, even if the combination of the combinations permitted by the flag cannot be made, the winning flag is not invalidated and is carried over to the next game. It becomes.

  As the role in this slot machine 1, as shown in FIG. 5, as a special role, big bonuses (1) to (3) (hereinafter, big bonus (1) is BB (1) and big bonus (2) is BB ( 2), big bonus (3) is BB (3)), cherry, watermelon and bell are defined as small roles, and replay is defined as a re-playing role.

  Cherry is awarded when a symbol of “white cherry” is derived on any of the winning lines for the right reel in any gaming state, and one medal is paid out. In addition, when the symbol of “white cherry” stops at the upper or lower stage of the right reel, the combination of cherries is aligned on the two winning lines of the winning lines L2, L5 or the winning lines L3, L4. Since winning a cherry on the winning line, two medals will be paid out.

  The watermelon is awarded when any combination of “watermelon-watermelon-watermelon” or “watermelon-watermelon-BAR” is arranged on any of the winning lines in any gaming state, and nine medals are paid out.

  The bell is awarded when a combination of “bell-bell-bell” is arranged on any of the winning lines in any gaming state, and nine medals are paid out.

  Replay is awarded when a combination of “Replay-Replay-Replay”, “BAR-Replay-Replay”, and “Black 7-Replay-Replay” is aligned on the winning line in the normal gaming state. When the replay wins, no medals are paid out, but the next game can be started without setting the number of wagers again, so that three medals corresponding to the number of wagers that are not required to be set in the next game are paid out. Is essentially the same.

  BB (1) is awarded when the combination of “Black 7-Black 7-Black 7” is aligned on the winning line in the normal gaming state, and BB (2) is “White 7-” on the winning line in the normal gaming state. The winning combination is achieved when the combination of “white 7-white 7” is completed, and BB (3) is awarded when the combination of “white 7-white 7-black 7” is aligned on the winning line in the normal gaming state.

  When any of BB (1) to (3) wins, the gaming state shifts to BB and simultaneously shifts to RB. The RB is a gaming state that is advantageous to the player over other gaming states by increasing the winning probability of the small role, particularly the bell. When the RB starts, when the eight games are consumed, or the four-game winning ( When the type of a combination is allowed), it ends either whichever comes first. When the RB is finished, if the BB is not finished, the process proceeds to the RB again, and the RB is repeatedly controlled until the BB is finished. That is, during BB, it is always controlled to RB. The BB triggered by the winning of the BB (1) (2) ends when the total number of medals paid out to the player in the BB exceeds 269, and the BB (3) wins. The BB to be completed ends when the total number of medals paid out to the player in the BB exceeds 69. At the end of the BB, the RB is also ended regardless of whether or not the RB end condition is satisfied.

  Hereinafter, the internal lottery of the present embodiment will be described. In the internal lottery, it is determined whether or not the above winning combination is permitted before the display results of all the reels 2L, 2C, and 2R are derived and displayed (actually, when the start switch 7 is detected). To do. In the internal lottery, first, a random number for internal lottery (an integer from 0 to 65535) is acquired. Then, for each combination determined according to the gaming state and whether or not the special combination is carried over, the acquired random number for internal lottery and the number of judgment values for each combination determined according to the gaming state, the number of bets and the set value Is done according to.

  In this embodiment, as shown in FIG. 6, the role is subject to internal lottery depending on whether the gaming state is the normal gaming state or RB (BB), and in the normal gaming state, the special role is different. The target of the internal lottery also varies depending on whether or not it is being carried over (normal: normal gaming state in which special roles are not carried over, winning: normal gaming state in which special roles are carried over).

  If the gaming state is the normal gaming state and the special role is not carried over, BB (1), BB (1) + watermelon, BB (1) + cherry, BB (2), BB (2) + Watermelon, BB (2) + cherry, BB (3), BB (3) + watermelon, BB (3) + cherry, replay, watermelon, cherry, and bell are sequentially read out as the internal lottery target roles.

  If the gaming state is the normal gaming state and the special combination is carried over, the replay, watermelon, cherry, and bell are sequentially read out as the target combinations for the internal lottery.

  If the gaming state is RB (BB), watermelon, cherry, and bell are sequentially read out as the subject combination of the internal lottery.

  In the internal lottery, the number of determination values determined corresponding to the role to be subject to the internal lottery, the current gaming state and the set value are sequentially added to the random number for the internal lottery, and when the result of addition overflows, It is determined that the winning combination has been won. For this reason, a winning combination will be won with a probability (number of determination values / 65536) according to the number of determination values. In this embodiment, when 6 is set as the set value, the number of determination values shown in FIG. 6 is used, and the winning probability of each combination is approximately the probability shown in FIG.

  In this embodiment, as shown in FIG. 6, watermelon and cherry can be won simultaneously with a special role, but the ratio of the probability of winning simultaneously with a special role in the winning probability of watermelon is the special role in the winning probability of cherry. If the watermelon wins, the chance of winning a special role can be expected more than if the cherry wins.

  In the internal lottery, when any winning combination is determined, a winning flag corresponding to the winning combination is set in the internal winning flag storing work assigned to the RAM 41c. The internal winning flag storage work consists of a 2-byte storage area, of which the upper byte is assigned as the special role storing work in which the winning flag for the special role is set, and the lower byte is the winning of the general role It is assigned as a general role storage work for which a flag is set. Specifically, when a special combination is won, a special combination winning flag indicating that the special combination is won is set in the special combination storing work, and the winning flag set in the general combination storing work is cleared. When a general combination is won, a winning flag for the general combination indicating that the general combination is won is set in the general combination storing work. If no winning combination is selected, only the general winning combination work is cleared.

  Next, stop control of the reels 2L, 2C, 2R will be described.

  The main CPU 41a refers to the table index and the table creation data stored in the ROM 41b when the rotation of the reel starts and when the reel stops and the reel that is still rotating still remains. Create a stop control table for each reel. When any of the stop switches 8L, 8C, and 8R corresponding to the rotating reel is effectively detected, the stop control table of the corresponding reel is referred to and the slip of the referred stop control table is referred to. Based on the number of frames, control is performed to stop the rotation of the reels 2L, 2C, 2R corresponding to the operated stop switches 8L, 8C, 8R.

  In the table index, an index that indicates the start address of the area in which the data for table creation is stored, from the reference address when referring to the table index, according to the setting state of the winning flag by internal lottery (hereinafter referred to as the internal winning state) Differences up to the address where the data is stored are registered. As a result, a difference corresponding to the internal winning state is acquired, and the corresponding index data can be acquired by adding the difference to the reference address. Even when the winning combinations are different, when the same control is applied, the same address is stored as the index data. In such a case, the same table creation data is referred to. Thus, a stop control table is created.

  The table creation data includes a stop control table indicating the number of sliding frames according to the stop operation position, and an address of the stop control table to be referred to according to the reel stop status.

  The stop control table referred to according to the reel stop status is whether all reels are rotating, only the left reel is stopped, only the middle reel is stopped, only the right reel is stopped, It may vary depending on whether the middle reel is stopped, the left and right reels are stopped, the middle and right reels are stopped, and if any reel is stopped, stop Since there may be differences depending on the stop position of the reels already completed, the address of the stop control table to be referenced for each situation is registered for each rotating reel, and based on the top address of the table creation data, It is possible to specify the address of the stop control table that should be referred to according to the status of each, and it is necessary according to each status from this specified address. And to be able to identify the stop control table. Even when the reel stop status and the stopped position of the stopped reel are different, when the same stop control table is applied, the same address may be registered as the address of the stop control table. In such a case, the same stop control table is referred to.

  The stop control table is data that can specify the number of sliding frames for each timing when the stop operation is performed. In this embodiment, stepping motors that make one turn at a cycle of 168 steps (0 to 167) are used for the reel motors 32L, 32C, and 32R. That is, when the reel motors 32L, 32C, and 32R are driven for 168 steps, the reels 2L, 2C, and 2R make one round. 21 areas (frames) divided every 8 steps (the number of steps in which one symbol moves) per reel are defined, and these areas are areas 0 to 20 from the reel reference position. A number is assigned. On the other hand, the number of symbols arranged on one reel is 21, and symbol numbers 0 to 20 from the reel reference position are assigned to symbols on each reel, so symbols 0 to 20 are assigned to each reel. , Area numbers 0 to 20 are assigned in order. In the stop control table, the number of sliding symbols for each area number is compressed and stored according to a predetermined rule, and the number of sliding symbols for each area number can be acquired by expanding the stop control table. Yes.

  As described above, the stop control table created by referring to the table index and the table creation data corresponds to the area number, and the area corresponding to each area number is the stop reference position (in this embodiment, the perspective window 3). Sliding frame when an operation of the stop switches 8L, 8C, 8R is detected at a timing (a timing in which the number of steps from the reel reference position is included in the range of the number of steps of each region number). It is a table with each number set.

  Next, the procedure for creating the stop control table will be described. First, at the start of reel rotation, the top address of the table creation data corresponding to the internal winning state of the game is acquired. Specifically, the table index is first referred to, index data corresponding to the internal winning state is obtained, table creation data is identified based on the obtained index data, and all reels are identified from the identified table creation data. The address of the stop control table for each reel corresponding to the state of rotation is acquired, and the stop control table for each reel stored at the acquired address is expanded to generate a stop control table for all reels.

  Further, when any one reel stops or any two reels stop, the index data acquired at the start of reel rotation, that is, the top address of the table creation data corresponding to the internal winning state of the game The table creation data is identified based on the table creation data, and the stop control table address of the unreacted reel corresponding to the stopped reel and the area number of the stop position of the reel is obtained from the identified table creation data. The stop control table for each stored reel is expanded to create a stop control table for the unstopped reels.

  Next, when the main CPU 41a effectively detects any one of the stop switches 8L, 8C, and 8R corresponding to the rotating reel, the control when the display result is derived to the corresponding reel will be described. When one of the stop switches 8L, 8C, and 8R corresponding to the rotating reel is effectively detected, the stop operation position area is determined based on the number of steps from the reel reference position when the stop operation is detected. The number is specified, the stop control table of the reel where the stop operation is detected is referred, and the number of sliding symbols corresponding to the area number of the specified stop operation position is acquired. Then, control is performed to rotate and stop the reel by the number of acquired sliding frames. Specifically, from the number of steps from the reel reference position at the time when the stop operation is detected, the number of steps from the acquired number of sliding frames to the stop is calculated, and the reel is rotated and stopped by the calculated number of steps. Take control. As a result, the area corresponding to the area number that is the stop position ahead of the number of sliding frames from the area corresponding to the area number of the stop operation position where the stop operation is detected is the stop reference position (in this embodiment, the perspective window 3 It will stop in the lower symbol area).

  In the table index of this embodiment, only one address is stored as index data corresponding to one internal winning state in one gaming state, and further, one table creation data includes one reel. Only one address is stored as the address of the storage area of the stop control table corresponding to the stop status (and the stop position of the stopped reel). In other words, table creation data corresponding to one internal winning state in one gaming state and stop control tables corresponding to reel stop states (and stopped positions of stopped reels) are uniquely determined. The stop control table created with reference to is unique for one internal winning state in one gaming state and the reel stop status (and the stop position of the stopped reel). Therefore, when all of the gaming state, the internal winning state, and the reel stop status (and the stop position of the stopped reel) are the same, the reel is based on the same stop control table, that is, the same control pattern. The stop control is performed.

  Further, in this embodiment, a value of 0 to 4 is determined as the number of sliding frames, and it is possible to stop the reel by drawing in a maximum of 4 symbols after detecting a stop operation. In other words, the stop position of the symbol can be designated from a range of a maximum of 5 frames including the stop operation position where the stop operation is detected. In addition, since it is necessary to move one frame to move the reel for one symbol, it is possible to stop the reel by pulling in a maximum of four symbols after detecting the stop operation. The symbol stop position can be designated from a range of up to five symbols including the operation position.

  In this embodiment, when any of the winning combinations is won, the winning combination is drawn on the winning line to the maximum in the range of 4 frames, and the winning combination is aligned on any winning line. Create a stop control table that defines the number of sliding frames to be pulled in to prevent reels from being stopped, and if none of the winning combinations are selected, slipping that does not match any winning combination on the winning line A stop control table with a defined number of frames is created and reel stop control is performed. As a result, when a stop operation is performed, if a winning combination can be stopped on any winning line in a drawing range of a maximum of 4 frames, control is performed to align and stop them. In this case, the winning combination is controlled so that the winning combination is stopped within a drawing range of a maximum of 4 frames.

  As shown in FIG. 3, the “bell” on the left reel, the “bell” on the middle reel, and the “bell” on the right reel, which constitute the bell, are arranged at intervals of 4 frames each. Regardless of the timing at which the reels are stopped, the “bell-bell-bell” combination is always on the winning line, and the bell wins. In addition, “Replay”, “BAR”, “Black 7” of the left reel, “Replay” of the middle reel, and “Replay” of the right reel, which are part of the replay, are arranged at intervals of 4 frames or less. Sometimes, any combination of “Replay-Replay-Replay”, “BAR-Replay-Replay”, or “Black 7-Replay-Replay” is always on the winning line, regardless of when the reels are stopped. As a result, Replay will win.

  On the other hand, the “white cherries” on the right reel that make up the cherries are arranged at intervals exceeding 7 frames. If you do it, the combination of “ANY-ANY-white cherry” will be on the winning line and the cherry will win, but if you stop the right reel at a timing outside the “white cherry” drawing range, You won't win a prize and you will miss it.

  In addition, the "watermelon" on the left reel, the "watermelon" on the middle reel, and the "watermelon" and "BAR" on the right reel that make up the watermelon are located at intervals exceeding 4 frames. If each reel is stopped at the timing of the “watermelon” drawing range, the combination of “watermelon-watermelon-watermelon” or “watermelon-watermelon-BAR” will be aligned with the winning line, and the watermelon will win. If any one of the reels is stopped at a timing outside the “watermelon” drawing range, the watermelon will not be won and will be missed.

  Also, BB (1) to (3) also have locations where the constituent symbols are arranged at intervals exceeding 4 frames, and even if any of BB (1) to (3) wins, the configuration of the winning BB If the reels are stopped at the timing of the symbol drawing range, the winning BB will win, but at any one of the reels, the stopping operation will be performed at a timing outside the winning BB component symbol drawing range. If you do, BB will not win and you will miss it. BB will be carried over to the next game even if it is missed as described above, so if you win BB once, for example, even if you miss it, you will be awarded by performing a stop operation at an appropriate timing after the next game Is possible.

  If the special role is elected while the special role has been carried over from before the previous game, or if the special role and the small role are elected at the same time when the special role is not carried over, the special role and the small role are won simultaneously. The number of sliding symbols is set so that the winning small role is drawn to the winning line within the range of 4 frames, and the winning small role is drawn to the winning line within the range of up to 4 frames. For stop operation positions that cannot be inserted, a stop control table in which the number of sliding symbols is determined so as to draw the selected special combination to the winning line in the range of 4 frames to the maximum is created, and reel stop control is performed. As a result, when a stop operation is performed, if it is possible to stop all the small roles that have been selected in the drawing range of up to 4 frames on the winning line and stop them, control is performed so that the winning combination is stopped. If you can't draw a small role that has been won in the drawing range of up to 4 frames on the line, if you can stop with a special role that has been won in the drawing range of up to 4 frames on the winning line, A control is performed to stop them in a uniform manner, and a winning combination that has not been won will be controlled to be stopped within a 4-frame pull-in range. That is, in such a case, priority is given to the control for aligning the small combination on the winning line over the special combination, and the special combination can be made effective only when the small combination cannot be drawn.

  In this embodiment, when a special role and a small role are simultaneously elected, the control for aligning the small role on the winning line is prioritized over the special role, and the special role is given only when the small role cannot be drawn. However, priority is given to the control of aligning the special role on the winning line over the small role, and it is possible to win the small role only when the special role cannot be drawn. It is good also as a structure.

  The special role and re-playing role are selected when the re-playing role is elected while the special role has been carried over from before the previous game, or when the special role and re-playing role are won at the same time without the special role being carried over. In the case of winning at the same time, when a stop operation is performed, control is performed so that the symbols of the re-gamer are aligned and stopped on the winning line within a drawing range of a maximum of 4 frames. In this case, the symbols constituting the re-playing combination are arranged within 5 symbols for each of the reels 2L, 2C, and 2R, that is, with an interval of 4 frames or less. Therefore, if a special combination and a replaying player are elected at the same time, the replaying game will always be awarded regardless of the operation timing of the stop switches 8L, 8C and 8R by the player. Will be. That is, in such a case, the control for aligning the re-games on the winning line has priority over the special game, and the re-games will always win.

  Next, commands that the main CPU 41a transmits to the effect control board 90 will be described.

  In the present embodiment, the main CPU 41a sends a BET command, a credit command, an internal winning command, a reel effect command, a reel rotation start command, a reel stop command, a winning determination command, a payout start command, a payout end command to the effect control board 90. A plurality of types of commands including a game state command, a standby command, a stop command, an error command, an initialization command, a setting end command, a power-on command, an operation detection command, and a door command are transmitted.

  These commands are composed of 1-byte type data indicating the type of command and 1-byte extension data indicating the content of the command, and the sub CPU 91a can determine the type of command from the type data.

  The BET command is a command that can specify the number of inserted medals, that is, the number of medals used to set the bet number, and is a state from the end of the game (after setting change) to the start of the game. Sent when a medal is inserted or the MAXBET switch 6 is operated to set the number of bets in a state where is not set. Further, since the BET command is transmitted when the betting number setting operation is performed, it is possible to specify that the betting number setting operation has been performed by receiving the BET command.

  The credit command is a command that can specify the number of medals stored as credits, and is a state from the end of the game (after setting change) to the start of the game, and in a state where a predetermined number of bets is set, Sent when a medal is inserted and credits are added.

  The internal winning command is a command that can specify the winning status of the internal winning flag and the type of the internal winning flag that has been established, and is transmitted when the start switch 7 is operated to start the game. Further, since the internal winning command is transmitted when the start switch 7 is operated, it is possible to specify that the start switch 7 has been operated by receiving the internal winning command.

  The freeze command is a command for notifying that the game is controlled to a freeze state to be described later in the next game, and is transmitted when control of the freeze state is started.

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

  The reel stop command is a command that can specify whether the reel to be stopped is the left reel, the middle reel, or the right reel, the area number of the corresponding reel stop operation position, and the area number of the corresponding reel stop position. And is transmitted each time stop control is performed in accordance with the stop operation of each reel. Since the reel stop command is transmitted when the stop switches 8L, 8C, and 8R are operated, it is possible to specify that the stop switches 8L, 8C, and 8R are operated by receiving the reel stop command. .

  The winning determination command is a command that can specify the presence / absence of winning, the type of winning, and the number of medals to be paid out at the time of winning, and is transmitted after all the reels are stopped and the winning determination is performed.

  The payout start command is a command for notifying the start of payout of medals, and is transmitted when the payout of medals is started by paying out a prize or credit (including medals used for setting the number of bets). The payout end command is a command for notifying the end of payout of medals, and is transmitted when the payout of medals by winning and winning a credit is completed.

  The game state command is a command that can specify the game state of the next game (whether it is the normal game state, the BB, the RB, or the like) and the currently set value, which will be described later. Sent after the setting end command is transmitted and at the end of the game.

  The standby command is a command indicating a transition to the standby state, and after one game is over, a credit (which was used for setting the bet number) is set when the transition to the standby state is made after a predetermined time without setting the bet number. (Including medals) is sent out after the medal payout is completed and the payout end command is sent.

  The stop command is a command indicating the occurrence or release of the stop state, and after the end of the BB, the stop command indicating the occurrence of the stop state is transmitted when the ending effect waiting time has elapsed, and the reset operation is performed. When the stop state is released, a stop command indicating the release of the stop state is transmitted.

  An error command is a command that indicates the occurrence or release of an error state. When an error is determined and controlled to the error state, an error command that indicates the occurrence of the error state is sent, and a reset operation is performed to release the error state. At that time, an error command indicating the cancellation of the error state is transmitted.

  The initialization command is a command indicating that the gaming state has been initialized and the start of the setting change mode, and is transmitted when the RAM 41c is initialized and shifts to the setting change mode.

  The setting end command is a command indicating the end of the setting change mode, and is transmitted when the setting ends, that is, when the setting change mode ends.

  The power-on command is a command that indicates whether or not one of the special roles has been won at power-on, and if it can be restored to the state before the power interruption at startup, it returns to the state before the power interruption. Sent when.

  The door command is a command indicating the detection state of the door opening detection switch 25, that is, ON (open state) / OFF (closed state). When the power is turned on, one game is finished (after the game is over, the bet number of the next game) Sent before the setting can be started), and when the detection state of the door opening detection switch 25 changes (ON to OFF, OFF to ON).

  The operation detection command indicates that the detection state of the operation switch that is not involved in the game progress control among the MAXBET switch 6, the start switch 7, the stop switches 8L, 8C, and 8R has changed from OFF to ON, or has changed from ON to OFF. This command is transmitted when the detection state of the operation switch not involved in the game progress control changes.

  Of these commands, commands other than the door command, error command, initialization command, and power-on command are generated in a startup process and a game process, which will be described later, and temporarily stored in a normal command transmission buffer provided in a special work in the RAM 41c. Are transmitted in the above-described timer interrupt processing (main).

  The error command, the initialization command, and the power-on command are generated in the above-described startup process, stored in a special command transmission buffer provided in the special work of the RAM 41c, and transmitted in the above-described timer interrupt process (main). .

  The door command is stored in a door command transmission buffer provided in a special work in the RAM 41c in the door monitoring process in the timer interrupt process (main) described above, and is transmitted in the timer interrupt process (main) described above.

  Next, the control of the effect performed by the sub control unit 91 based on a command transmitted from the main CPU 41a to the effect control board 90 will be described.

  The sub CPU 91a executes a command reception interrupt process when a strobe signal indicating the transmission of a command from the main CPU 41a is input. In the command reception interrupt process, the command acquired from the command transmission line is stored in the reception buffer provided in the RAM 91c.

  In the timer interrupt process (sub), the sub CPU 91a determines whether or not an unprocessed command is stored in the reception buffer. If an unprocessed command is stored, the sub CPU 91a is the earliest stage. Based on the received command, the control pattern table stored in the ROM 91b is referred to. Based on the control contents registered in the control pattern table, various effects such as the liquid crystal display 51, the effect LED 52, the speakers 53 and 54, the reel LED 55, etc. Control the device.

  In this embodiment, the time interval (1.12 ms) at which the sub CPU 91a performs the timer interrupt process (sub) is shorter than the time interval (2.24 ms) at which the main CPU 41a transmits a command. If an operation associated with a normal game is performed, an unprocessed command stored in the reception buffer is not received until the next command is received even when commands are continuously transmitted from the main CPU 41a. It is read by the timer interrupt process (sub), and a plurality of unprocessed commands are not accumulated in the reception buffer. When a command transmitted from the main CPU 41a is received, the timer interrupt process performed first after that The command received by (sub) is read and processing corresponding to the command is performed.

  In the control pattern table, the display pattern of the liquid crystal display 51 corresponding to the type of command, the lighting mode of the lighting effect LED 52, the output mode of the speakers 53 and 54, the lighting mode of the reel LED, etc. The control patterns of these effect devices are registered, and when the sub CPU 91a receives the command, the sub CPU 91a, among the control patterns registered corresponding to the effect patterns set in the RAM 91c in the game of the control pattern table, With reference to the control pattern corresponding to the received command type, the rendering device is controlled based on the control pattern. Thereby, the production according to the production pattern and the progress of the game is executed.

  If the sub CPU 91a receives a new command during execution of an effect triggered by the reception of a certain command, the sub CPU 91a stops the effect based on the control pattern being executed, and responds to the newly received command. An effect based on the control pattern is executed. In other words, even if the production is not finished to the end, when a new command is received, the production that was being executed is canceled and a new command is received unless the received new command is not a command that triggers a new production. An effect based on the command is executed.

  In particular, in this embodiment, when an operation for setting the number of bets is performed during execution of an effect, that is, when the sub CPU 91a receives a BET command indicating that the number of bets has been set, the effect being executed is canceled. It is supposed to be. For this reason, if the player wants to proceed to the next game rather than seeing the production to the end, the production is canceled and the next game can be started. There is no. Further, when a credit or bet amount adjustment operation is performed during the performance, that is, after the sub CPU 91a receives a game state command indicating the end of the game, and before receiving an internal winning command indicating the start of the game. When the payout start command is received, the performance being executed is stopped. Credits and bets are settled when the game is terminated. In such a case, by terminating the performance that is being executed, there is an intention to end the game, but the performance continues unnecessarily. It is designed not to be overwhelmed. In the case of controlling the bet number setting operation, credits, and bet amount adjustment operation to be disabled (BET freeze state) during the performance, the bet number setting operation and the adjustment operation are performed during that time. Even if the operation is performed, the BET command or the payout start command is not transmitted, and as a result, the effect that is being executed is not canceled in accordance with these operations.

  When the internal winning command is received, the effect pattern is selected at a selection rate corresponding to the result of the internal lottery indicated by the internal winning command, and is set in the RAM 91c. When the freeze command is received, the performance pattern is selected with a probability corresponding to whether the internal lottery result indicated by the internal winning command received immediately before indicates BB winning or RB winning. Are set in the RAM 91c. The selection rate of the production pattern is registered in the production table stored in the ROM 91b, and when the sub CPU 91a receives the internal winning command, the sub CPU 91a uses the selection rate registered in the production table according to the result of the internal lottery. With reference to this, one of the effect patterns is selected from a plurality of types of effect patterns according to the selection rate, and the selected effect pattern is set in the RAM 91c as the effect pattern of the game.

  The control pattern table contains specific controls that are referred to when a specific command (standby command, stop command, error command, initialization command, setting end command, power-on command indicating that special role is elected, etc.) is received. When the pattern is stored and the sub CPU 91a receives these specific commands, the sub CPU 91a refers to the specific control pattern corresponding to the command regardless of the effect pattern set in the game, and The rendering device is controlled based on the pattern.

  When a standby command is received, a demo pattern for executing a demonstration effect (demonstration effect) is referred to as a control pattern. In addition, when the final effect that informs the winning of the special role is being executed, the execution of the demo effect is prohibited, and the demo pattern is controlled even if a standby command is received in such a state. It is not referred to as a pattern, and no demonstration effect is executed.

  When a stop command indicating the occurrence of a stop state is received, a stop notification pattern for notifying that the stop state is in effect is referred to as a control pattern. When a stop command indicating release of the stop state is received, the above-described demo pattern is referred to as a control pattern. That is, when the stop state is released, the demonstration effect is executed.

  When an error command indicating the occurrence of an error state is received, an error notification pattern for notifying the fact of the error state and its type is referred to as a control pattern. When an error command indicating the cancellation of the error state is received, the control pattern that was being executed when the error occurred is referred to. That is, the production at the time of error occurrence is executed from the beginning.

  When the initialization command is received, a setting notification pattern for notifying that the setting is being changed is referred to. When the setting end command is received, the demo pattern described above is referred to as a control pattern. In other words, when an initialization command is received, a notification during setting change is executed, and when a setting end command is received thereafter, a demonstration effect is executed.

  When a power-on command indicating that a special role is won is received, a special role notification pattern for notifying that the special role has been won is referred to. That is, when a power-on command indicating that the special role is won is received, a notification effect for notifying that the special role is won is executed. Note that the notification effect for notifying the winning of the special combination is once executed until it receives a winning determination command indicating that the special combination has won.

  In the present embodiment, a freeze lottery is performed when a cherry or watermelon that may be elected simultaneously with a special role is won. In the freeze lottery, it is determined whether to control the freeze state in the next game according to the result of the internal lottery.

  If the main CPU 41a decides not to control the freeze state in the freeze lottery, as shown in FIG. 8 (a), after the start of the next game, when the rotation of the rule is started, the main CPU 41a immediately accelerates and all reels When the rotation speed becomes constant speed, the operation of the stop switches 8L, 8C, 8R corresponding to each reel is validated.

  On the other hand, when it is determined to control the freeze state by freeze lottery, as shown in FIG. 8B, after the start of the next game, stop switches 8L, 8C corresponding to each reel until the freeze period elapses. The operation of the stop switches 8L, 8C, 8R corresponding to each reel is validated when the freeze period elapses without validating the operation of 8R.

  FIG. 7 is a diagram showing the winning probability and the appearance rate of the freeze lottery for each winning combination.

  In the present embodiment, the probability of winning the freezing lottery in the order of special role + watermelon, special role + cherry, watermelon and cherry is high.

  In addition, the probability of winning a freezing lottery when winning a special role + watermelon is higher than the probability of winning a freezing lottery when the watermelon alone is won, and it is frozen by winning the watermelon after being controlled to the frozen state. You can expect to win a special role as compared to the case where you win a watermelon without a bonus.

  In addition, the probability of winning the freezing lottery when winning the special role + cherry is higher than the probability of winning the freezing lottery when winning alone, and the freezing state is achieved by winning the cherry after being controlled to the freezing state. You can expect to win a special role as compared to the case where you won the cherry without winning.

  In addition, the probability that BB + watermelon wins and wins the freeze lottery and the ratio of the former probability to the probability that watermelon wins alone and wins the freeze lottery, the probability that BB + cherry wins and wins the freeze lottery, If one of the watermelons or cherries wins with a frozen state, it is higher than the ratio of the probability of the cherry winning alone and winning the freeze lottery. You can expect to win a special role compared to when you win the Cherry.

  As shown in FIG. 8B, the main CPU 41a of the present embodiment changes the reels in the above-described freeze period, that is, a period in which the activation of the operation of the stop switches 8L, 8C, 8R is delayed after the start of the game. The reel production control for producing the production is performed.

  The reel effect control means that the reels are rotated in synchronism so that the same combination of symbols is aligned on the three rotating reels, and the possibility of winning the special role according to the type of symbols aligned on the straight line. This is a suggestion.

  Further, as shown in FIG. 8B, the main CPU 41a performs reel effect control after the start of the game when controlling the freeze state. In reel effect control, as shown in FIGS. 9 (a) and 9 (b), the reels start to rotate, and the relative positional relationship between the reels so that the corresponding symbols are aligned on a straight line according to the selected control pattern. To control. For example, in the case of a control pattern in which “black 7” is aligned on a straight line, as shown in FIG. 9B, the relative positional relationship of each reel so that “black 7” is aligned on a straight line. The reel is rotated so that

  Next, after the reel effect control, the main CPU 41a performs initial position return control as shown in FIG. In the initial position return control, while maintaining the rotation of the reel, as shown in FIG. 9C, each reel has an initial positional relationship that is a relative positional relationship of each reel at the end of the previous game. Control the relative positional relationship between In this embodiment, the stop position of each reel at the end of the previous game is held until the end of the next game, and the initial position relationship is determined from the stop position of each reel at the end of the previous game. Can be specified.

  Next, after the initial position return control, the main CPU 41a performs initial position notification control as shown in FIG. In the initial position notification control, after the synchronous rotation while maintaining the initial positional relationship that is the relative positional relationship of each reel at the end of the previous game, the stop position stopped at each reel at the end of the previous game. Then, each reel is temporarily stopped to notify the player that the reel has returned to the initial position, and then the reel rotation is started again while maintaining the initial positional relationship.

  Then, after the initial position notification control, the main CPU 41a accelerates the reel rotation speed and, as shown in FIGS. 8B and 9D, when the constant speed rotation is reached, the stop switch 8L, Enables 8C and 8R operations.

  In addition, the sub CPU 91a performs control to change the visibility of the reel by performing turning on / off control of the reel LED 55 in accordance with the reel effect control, the initial position return control, and the initial position notification control in the freeze period. The reel LED 55 on / off control in accordance with the reel effect control, the initial position return control, and the initial position notification control is performed by specifying the display position of each reel when the reel is stopped from the reel stop command described above. This is done according to the position.

  During the reel effect control, as shown in FIG. 9A, the reel LED 55 is sequentially turned off from the area corresponding to the upper symbol in accordance with the rotation of the reel, and the symbols that can be aligned by the reel effect control. That is, in accordance with the passage of “Black 7”, “BAR”, “Watermelon”, and “Cherry”, the reel LED 55 in the area through which the symbol passes is turned on, and the other areas are turned off. As shown in FIG. 4, after the symbols corresponding to the control pattern are arranged in a straight line, the reel LED 55 in the area through which the symbol passes is turned on in accordance with the passage of the symbols arranged in the straight line. Control to turn off the other areas. For example, if “black 7” is aligned on a straight line, the area through which “black 7” passes is turned on in accordance with the passage of “black 7”, and the other areas are turned off. The visibility of the reels is changed so as to emphasize the aligned symbols.

  Next, during the initial position return control, after the reel LEDs 55 in all the areas are once turned off, when the relative positional relationship of each reel returns to the initial positional relationship, it stops at each reel at the end of the previous game. The reel LED 55 is turned on in accordance with the passage of the three consecutive symbols serving as the stop positions, and the other areas are turned off.

  Next, in the initial position notification control, the reel LEDs 55 in all the areas are blinked when the stop position stopped on each reel at the end of the previous game is temporarily stopped, and stopped on each reel at the end of the previous game. Emphasize that you have returned to the stop position you were using. Next, when the rotation of the reels starts again, the reel LEDs 55 in all the regions are turned on, and then the operation of the stop switches 8L, 8C, 8R is validated, and all the reels stop with the stop operation. Up to this point, the lighting state of the reel LEDs 55 in all regions is maintained.

  The main CPU 41a determines whether the BB (1) (2) has been won, the BB (3) has been won, or the special role has not been won at the start of the next game in which it is determined to control the freeze. Or a control pattern selection lottery that randomly selects a control pattern of reel effect control executed during the freeze period from a plurality of control patterns with a probability according to whether or not.

  As shown in FIG. 10A, the control patterns are composed of seven patterns 1-7.

  Pattern 1 is a pattern in which “Cherry” is finally aligned in a straight line by forward rotation, Pattern 2 is a pattern in which “Watermelon” is finally aligned in a straight line by forward rotation, and Pattern 3 is in a forward rotation Finally, the pattern “BAR” is arranged in a straight line, pattern 4 is a pattern in which “black 7” is finally arranged in a straight line by forward rotation, and pattern 5 is finally “cherry” in a reverse rotation. The pattern 6 aligned on a straight line is a pattern in which “watermelon” is finally aligned on a straight line by reverse rotation, and the pattern 7 is a pattern in which “BAR” is finally aligned on a straight line by reverse rotation.

  Each of these patterns is selected with the probability shown in FIG. 10A by the control pattern selection lottery.

  In this embodiment, as shown in FIGS. 10 (b)-(1), the selection rate at the time of winning one of BB (1) to (3) of pattern 1: a1 + b1, the selection rate at the time of non-winning BB: c1 The ratio of the selection rate at the time of winning one of the BBs (1) to (3) of the pattern 1 occupying the total value of: any of the BBs (1) to (3) of the pattern 2 than (a1 + b1) / (a1 + b1 + c1) Selection rate at the time of winning: a2 + b2, selection rate at the time of non-winning BB: ratio of the selection rate at the time of winning any of BB (1) to (3) of pattern 2 in the total value of c2: (a2 + b2) / ( (a2 + b2 + c2) is determined so that the lottery probability is high, and the selection rate at the time of winning of any of BB (1) to (3) of pattern 5: a5 + b5, the selection rate at the time of non-winning BB: the sum of c5 Ratio of the selection rate at the time of winning any of BB (1) to (3) of pattern 5: (a5 + b5) / (a5 + b5 + c5) than at the time of winning any of BB (1) to (3) of pattern 6 Selection rate: a6 + b6, selection rate at BB non-winning: the ratio of the selection rate at the time of winning any of BB (1) to (3) of pattern 6 in the total value of c6: (a6 + b6) / (a6 + b6 + c6) The lottery probability is set to be higher.

  For this reason, in the reel control production, it is determined that one of the BBs (1) to (3) is won when the “watermelon” is arranged in a straight line rather than the “cherry” is arranged in a straight line. Can be expected.

  Further, in this embodiment, as shown in FIGS. 10B to 10B, the selection rate at the time of winning one of the BBs (1) to (3) of the pattern 1: the BB (1 of the pattern 1 occupying the a1 + b1 ) (2) Selection rate at any one of winning: Ratio of a1: a1 / (a1 + b1) Rather than a1 / (a1 + b1), selection rate at any of BB (1) to (3) of pattern 2: Pattern 2 occupying a2 + b2 BB (1) to (3) The selection ratio at the time of winning: The ratio of a2: The ratio of a2 / (a2 + b2) is determined so that the lottery probability is high, and BB (1) to (3) of pattern 5 Selectivity at any win: BB of pattern 5 in a5 + b5 (1) (2) Selectivity at any win: ratio of a5: BB (1) of pattern 6 than a5 / (a5 + b5) ~ (3) any Selectivity at winning: a6 + b6 accounted pattern 6 of BB (1) (2) selectivity at the time of any of the winning: Ratio of a6: a6 / (a6 + b6) are lottery probability is set such increases.

  For this reason, in the reel control effect, BB (1) to (3), which has a higher advantage than BB (1) to (3), has a higher advantage than BB (1) to (3). 1) I can expect that I won (2).

  Further, in this embodiment, as shown in FIGS. 10B to 10C, the selection rate at the time of winning one of the BBs (1) to (3) of pattern 1: a1 + b1, the selection rate at the time of non-winning BB : Ratio of the selection rate at the time of winning any of BB (1) to (3) of pattern 1 in the total value of c1: BB (1) to (3) of pattern 5 than (a1 + b1) / (a1 + b1 + c1) Selectivity in any winning: a5 + b5, Selectivity in non-winning BB: Ratio of selectability in any winning of pattern 5 in BB (1) to (3) in the total value of c5: (a5 + b5) / (A5 + b5 + c5) is determined so that the lottery probability is high, and the selection rate at the time of winning of any one of BB (1) to (3) of pattern 2: a2 + b2, the selection rate at the time of non-winning BB: the sum of c2 The ratio of the selection rate at the time of winning any of BB (1) to (3) of pattern 5 in the value: winning of any of BB (1) to (3) of pattern 6 rather than (a2 + b2) / (a2 + b2 + c2) Selectivity at the time: a6 + b6, Selectivity at the time of BB non-winning: Ratio of selectivity at the time of winning any of BB (1) to (3) of the pattern 6 in the total value of c6: (a6 + b6) / (a6 + b6 + c6) The lottery probability is determined so as to increase.

  For this reason, in the reel control effect, when “Cherry” or “Watermelon” is finally aligned on a straight line, “Cherry” or “Watermelon” is aligned in a reverse rotation rather than aligned in a straight line. The direction where “cherry” or “watermelon” is arranged in a straight line can be expected for winning BB (1) to (3).

  Further, in this embodiment, as shown in FIGS. 10B to 10B, the selection rate at the time of winning one of the BBs (1) to (3) of the pattern 1: BB (1 of the pattern 1 occupying a1 + b1 ) (2) Selection ratio at any one of winning: Ratio of a1: a1 / (a1 + b1), Pattern 5 occupying BB (1) to (3) at any winning of pattern 5: a5 + b5 BB (1) to (3) The selection probability at the time of winning: The ratio of a5: a5 / (a5 + b5) is determined so that the lottery probability is high, and BB (1) to (3) of pattern 2 Selectivity at any win: BB of pattern 2 occupying a2 + b2 (1) (2) Selectivity at any win: ratio of a2: BB (1) of pattern 6 than a2 / (a2 + b2) ~ (3) any Selectivity at winning: a6 + b6 accounted pattern 6 of BB (1) (2) selectivity at the time of any of the winning: Ratio of a6: a6 / (a6 + b6) are lottery probability is set such increases.

  For this reason, in the reel control effect, when “Cherry” or “Watermelon” is finally aligned on a straight line, “Cherry” or “Watermelon” is aligned in a reverse rotation rather than aligned in a straight line. The direction where “cherry” or “watermelon” is arranged in a straight line can be expected from winning BB (1) (2), which has higher advantage among BB (1) to (3).

  Further, in this embodiment, since the patterns 3, 4, and 7 can be selected only when BB (1) to (3) are won, in the reel control effect, finally "BAR" or "black" When “7” is aligned, it is shown that BB (1) to (3) are always selected. In particular, since the pattern 4 can be selected only when BB (1) (2) has been won, when the “black 7” is finally aligned, BB (1) to (3) It is determined that BB (1) (2) having higher advantage is won.

  Further, in this embodiment, as shown in FIGS. 10B to 10 (5), the selection rate at the time of winning one of the BBs (1) to (3) of the pattern 3: the BB (1 of the pattern 3 occupying the a3 + b3 ) (2) Selection ratio at any one of winning: Ratio of a3: Pattern 7 occupying a selection ratio at any of BB (1) to (3) of pattern 7: a7 + b7 rather than a3 / (a3 + b3) The selection probability at the time of winning either BB (1) or (2): ratio of a7: a7 / (a7 + b7) is determined so that the lottery probability is high.

  For this reason, in the reel control effect, when “BAR” is finally aligned on a straight line, “BAR” is aligned on a reverse rotation rather than “BAR” is aligned on a straight line in forward rotation. However, it can be expected that BB (1) (2) having higher advantage among BB (1) to (3) is won.

  As described above, in the slot machine 1 of the present embodiment, the relative positions of the three reels in the freeze period in which the activation of the operation of the stop switches 8L, 8C, and 8R is delayed after the game is started. Since reel effect control is performed so that the relationship is a specific positional relationship, that is, “Cherry”, “Watermelon”, “BAR”, or “Black 7” is aligned in a straight line, reel fluctuation during the freeze period It is possible to produce an impact with an aspect.

  In addition, while holding the stop position of each reel at the end of the game until the end of the next game, and performing the reel effect control, the operation of the stop switches 8L, 8C, and 8R is effective after the reel effect control. Before the game is made, the relative positional relationship of the three reels is returned to the initial positional relationship, that is, the relative positional relationship at the end of the previous game specified from the stop position of each reel at the end of the previous game. Even when the reel effect control is performed in such a manner that any one of “cherry”, “watermelon”, “BAR”, and “black 7” is arranged in a straight line, such reel effect control is performed. Even if there is not, after the operation of the stop switches 8L, 8C, 8R becomes effective, it is difficult to stop the reels with these stop switches 8L, 8C, 8R. There without change, even when subjected to reel performance control can be ensured fairness of the game.

  In this embodiment, after the reel effect control, before the operation of the stop switches 8L, 8C, and 8R is validated, not only the relative positional relationship of the three reels is returned to the initial positional relationship, After returning to the initial positional relationship, the control that suggests returning to the initial positional relationship, i.e., the initial positional relationship that is the relative positional relationship of each reel at the end of the previous game, and the previous game Each reel is temporarily stopped at the stop position that was stopped at the end of each reel, and control is performed to notify the player that the reel has returned to the initial position. It is possible to notify the player that the design has returned to the initial positional relationship, rather than the positional relationship where some symbols are aligned on a straight line by the production control, and the positional relationship where some symbols are aligned on a straight line. Misunderstanding to stop switch 8L, 8C, that reel stop operation will be performed by 8R can be prevented.

  In this embodiment, each reel is stopped at the stop position where the reels were stopped at the end of the previous game after the synchronous rotation while maintaining the initial positional relationship that is the relative position of the reels at the end of the previous game. Is temporarily informed to the player that the vehicle has returned to the initial position, but it may be configured to notify the player that at least the vehicle has returned to the initial position. A configuration in which the player is informed that the player has returned to the initial position by performing synchronous rotation more slowly than usual while maintaining the initial positional relationship that is the relative positional relationship of each reel at the end of the previous game, the previous game After the synchronous rotation with the initial positional relationship that is the relative positional relationship of each reel at the end, when the stop position stopped on each reel at the end of the previous game passes, the corresponding stop position passes By irradiating the corresponding area with the reel LED 55 in accordance with the above, an effect similar to the above can be obtained even in a configuration in which the player is notified of the return to the initial position.

Also, in this embodiment, by holding the stop position of each reel at the end of the game until the end of the next game, it becomes possible to specify the stop position of each reel at the end of the previous game. From the stop position of each reel, the initial positional relationship before the positional relationship between the reels is changed by reel effect control is specified, and after the game starts, the positional relationship between the reels at that time is detected It is possible to immediately start the reel effect control without performing the above control, that is, without waiting for the reference positions to be detected in all the reels.
In this embodiment, the stop position of each reel at the end of the game is held until the end of the next game. However, at least after the reel effect control is ended, it is held until the initial position return control is performed. Any configuration may be used, and the configuration may not be maintained thereafter. In addition, when it is determined that the reel effect control is not performed, the stop position of each reel at the end of the game may not be held after that time. Further, in the configuration for determining whether or not to perform reel effect control (freeze state) in the previous game as in the present embodiment, only when it is determined to perform reel effect control in the next game, Any configuration may be used as long as the stop position of each reel is held at least after the end of the reel effect control until the initial position return control is performed.

  Further, in this embodiment, the reel effect control is performed during the freeze period, and accordingly, the effect of changing the visibility of the reel is performed by controlling the turning on / off of the reel LED 55, and the change of the reel accompanying the reel effect control is performed. In addition to enhancing the effect of the aspect, it is possible to effectively notify the player that the initial position relationship has been returned in the initial position notification control after the reel effect control.

  In addition, the effect of changing the visibility of the reel by turning on / off the reel LED 55 is performed only in the freeze period, that is, the period until the operation of the stop switches 8L, 8C, 8R is validated, and the stop switch 8L, After the reel stop operation by 8C and 8R becomes effective, until all the reels stop, the reel LEDs 55 corresponding to all the regions are kept lit, and the visibility of the reels does not change. Therefore, it is possible to perform an effect of changing the visibility of the reel without changing the difficulty level of the reel stop operation by the stop switches 8L, 8C, 8R.

  In this embodiment, the reel visibility is changed by turning on / off the reel LED 55. For example, the reel is irradiated from the front side rather than from the rear side, or to the front side of the reel. Even in the configuration in which the visibility of the reel is changed by using the arranged transmissive display, the effect of changing the visibility of the reel as described above is performed only during the freeze period, and the stop switches 8L, 8C, 8R After the reel stop operation is enabled, the visibility of the reels is not changed until all reels are stopped, thereby changing the difficulty of the reel stop operation by the stop switches 8L, 8C, 8R. It is possible to produce an effect that changes the visibility of the reels.

  Further, in this embodiment, the visibility is different between the period during which the reel effect control is performed in the freeze period and the other period (the period during which the initial position return control and the initial position notification control are performed). In the freeze period, it is possible to easily determine whether the reel effect control is being performed or another period from the difference in the visibility of the reel.

  In this embodiment, in the reel production control, the possibility of winning BB is suggested, and the suggested BB can be won according to the difference in the symbols arranged in a straight line and the rotation direction until the symbols are arranged. The possibility of winning BB (1) (2), which is more advantageous among BB (1) to (3), is different. Since it is possible to estimate the winning expectation degree of BB and the more advantageous expectation degree of BB (1) (2) from the rotation direction, it is possible to further enhance the interest by reel effect control.

  In this embodiment, the configuration suggests the possibility of winning BB (1) to (3) accompanied by the transition to BB which is advantageous to the player by the reel effect control. However, for the player by the reel effect control. Any configuration that suggests an advantage may be used. For example, when the result of the internal lottery is a specific result, a plurality of displays having different advantages for the player according to the operation mode of the stop switches 8L, 8C, and 8R. In the configuration in which the result can be derived, when the result of the internal lottery becomes a specific result, the advantageous operation mode notification means for notifying the operation mode of the stop switches 8L, 8C, 8R advantageous to the player, and the internal lottery An advantage determining means for determining the advantage by the advantageous operation mode notifying means according to the result, and suggesting the advantage determined by the advantage determining means by the reel effect control It may be so that. In this case, the advantage determined by the advantage determining means is whether or not the advantageous operation mode notifying unit is activated, the probability that the advantageous operation mode notifying unit is activated, the number of rights to activate the advantageous operation mode notifying hand, and the like. Applicable. Furthermore, in the case of providing a first state in which a relatively high advantage is easily determined by the advantage determination means and a second state in which a relatively low advantage is easily determined, the reel effect control is used. The possibility of being controlled to the first state may be suggested.

  In addition, in this embodiment, when a watermelon or cherry that can be won at the same time as a special role in the previous game is won and won in the freeze lottery, the reel is controlled in the freeze state, and the reel is in the freeze period associated with the freeze state. The production control is performed, and the player's expectation for the special role winning can be effectively enhanced by the reel production control.

  In this embodiment, when a watermelon or cherry that can be won at the same time as the special role in the previous game is won and won in the freeze lottery, the reel is controlled in the freeze state and the reel is in the freeze period associated with the freeze state. Although the production control is performed, when the watermelon or cherry that can be won at the same time as the special role in the previous game is won, it is uniformly controlled to be frozen, and the reel production control is performed during that time. good. Also, the display result suggesting the possibility of winning the special role in the previous game (a watermelon or cherry winning mode that can be won at the same time as the special role, which is not a winning mode, but the special role is more The chance to appear at the time of winning and the chance to suggest that the special role is likely to be won, etc.) was derived, and the reel production was performed during the freeze period associated with the freeze state. Even when the control is performed, the reel expectation control can effectively increase the player's expectation for winning the special role.

  Also, in this embodiment, in the normal gaming state, when a watermelon or cherry that can be won at the same time as a special role is won, a freeze lottery is performed and the freeze lottery is won, and the reel effect control is performed during that time. However, it may be possible to control to a freeze state only in a specific gaming state among a plurality of gaming states, and a reel effect control may be performed during that time. Only in the gaming state, the freeze effect is controlled, and the reel effect control is not performed during that time, and the rarity is increased. Therefore, the player's satisfaction can be enhanced by the reel effect control.

  Note that the specific game state is, for example, a state of a certain period after the end of the BB, a state of a certain period after winning or winning a specific combination, or a re-playing amount having a higher probability of winning a re-gamer than the normal game state. Applicable to probability states. In addition, the above-described advantage determining means can easily determine a higher advantage only during BB or during BB, and it is possible to apply the BB as a specific gaming state. It is also possible to apply the first gaming state in which the above-described advantage determining means can easily determine a higher advantage as a specific gaming state.

  Although the embodiments of the present invention have been described with reference to the drawings, the present invention is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. Needless to say.

  For example, in the above embodiment, a slot machine for setting bets using medals and credits is used. However, the present invention is not limited to this, and a slot machine for setting bets using game balls.
