Description

  The present invention relates to a pachinko machine or other game machine equipped with a control means such as a microcomputer.

For example, in a pachinko machine that is a kind of gaming machine, when a game ball passes through a predetermined gate, a variable display of a symbol (hereinafter referred to as “normal symbol”) displayed by a 7-segment LED display device or the like is started. When a predetermined symbol (generally “7”) is stopped and displayed after a predetermined time, the ordinary electric accessory is opened (a state where it is easy to start a prize). A plurality of symbols (hereinafter referred to as “special symbols”) displayed on an electrical display device such as a liquid crystal display device start to fluctuate when a game ball wins a normal electric accessory being opened, and after a predetermined time. Special advantage that is advantageous for the player when the stop is displayed in a predetermined stop mode (stop mode with the same special symbols as "7-7-7", generally called "big hit") Those that transition to the gaming state are known. In such a pachinko machine, after the special gaming state is finished, the gaming state becomes higher in the probability of shifting to the special gaming state (hereinafter referred to as “probability variation state”), and the special symbol is changed and displayed for a certain number of times. For a limited period, the time from the start of fluctuation display of the normal symbol to the end of fluctuation display is shortened (for example, the fluctuation time of the normal symbol that is 50 seconds except for the probability fluctuation state, and the special symbol is changed 50 times in the probability fluctuation state. Some of them are designed to make it easier for game balls to win by frequently opening ordinary electric accessories.

Display control of the display means based on the effect, and display control means (for example, LED display control circuit 90 to be described later) for controlling the display means to display the display result corresponding to the determination result of the transition determining means, and the display A winning control means for performing control to change the winning device from the second state to the first state when the display result displayed on the means is a display result corresponding to the winning, the transition determining means, When a specific variation display effect that informs in a predetermined manner the timing at which the winning device changes from the second state to the first state is selected by the effect selecting means, If a non-specific variation display effect that does not notify the timing at which the winning device transitions from the second state to the first state by the effect selection means in a predetermined manner is selected, either win or not A gaming machine that is characterized by being determined .

In the embodiment of the present invention, the display means performs variable display of the normal symbol, the effect selection means selects one variable display mode from the variable display modes of a plurality of predetermined normal symbols, and the display control means In addition to performing variable display control of the normal symbol based on the variable display mode selected by the effect selection unit, control for displaying the variable display result of the normal symbol corresponding to the determination result of the transition determination unit on the display unit is performed. The control means performs control for shifting the winning device from the second state to the first state when the variable display result of the normal symbol displayed on the display means becomes a variable display result corresponding to the winning combination. The determining means determines whether the winning device is in the second state by changing the speed of the normal symbol variable display to a predetermined speed before the predetermined time before the variable display result of the normal symbol is displayed by the effect selecting means. When a specific variation display effect that informs the timing of transition to the first state is selected, it is determined that it will be a hit, and a predetermined time before the variable display result of the normal symbol variation display is displayed by the effect selection means If a non-specific variation display effect that does not notify the timing at which the winning device changes from the second state to the first state by not changing the speed of the variation display of the normal symbol to a predetermined speed is selected. Then, it is characterized in that it is determined as either not hit or not.

In the embodiment of the present invention, a game execution means for executing a game of a plurality of types of game states different from the special game state, a game state determination means for determining the type of game state being executed by the game execution means, and a specification And an effect selection table storage means in which a plurality of types of effect selection tables having different probabilities of selecting the variable display effects are stored corresponding to the game state executed by the game execution means, and the effect selection means Selecting an effect selection table corresponding to the gaming state determined by the gaming state determining means, and selecting either a specific variation display effect or a non-specific variation display effect based on the selected effect selection table It is characterized by .

In the embodiment of the present invention , the effect selection means can execute a plurality of types of non-specific variation display effects with different contents of the effect, and the hit determination table having different probabilities of being determined by the shift determining means is the effect selection means. A hit determination table storage means stored in correspondence with the selection result is provided, and the transition determination means selects a hit determination table corresponding to the selection result of the effect selection means, and based on the selected hit determination table, It is characterized by determining whether to do .

According to the present invention, the selecting means selects one effect from a plurality of predetermined effects (for example, an effect pattern shown in FIG. 12 described later). The transition determining means determines whether or not to change the winning device from the second state to the first state based on the selection result of the selecting means. The display control means controls the display means based on the determination result of the determination means. For example, the player pays attention to the displayed effect by including an effect as expected by the player in the plurality of effects.

Te embodiment odor of the present invention, since at least one of the effect of the effect of multiple is a demonstration for notifying the timing of transition from the winning device is the second state to the first state, a player that It can have a sense of expectation that an effect for notifying timing is selected. Specifically, if the timing notifies, for example, a “launch start timing” to be described later, it becomes easier for the player to win a game ball in the winning device. When the game ball wins the winning device, for example, a special symbol is displayed as a trigger for paying out a prize ball, which will be described later, and shifting to a special game state, so that it is possible to have fun aiming for winning.

  Also, in the effect of informing the timing, the speed of the normal symbol variation display changes. For example, when the speed of the normal symbol variation display described later changes from high speed to low speed, the player changes the normal symbol variation. The timing at which the winning device changes from the second state to the first state can be seen from the change in the display speed.

  The production shows the probability that the winning device changes from the second state to the first state, so that the player sees the production and knows the probability that the winning device changes from the second state to the first state. Can do. Specifically, for example, when it is determined to be “winning”, the probability that an effect in which the fluctuation display of the normal symbol changes from high speed to low speed (for example, “low-speed fluctuation display effect for normal state” described later) is selected. If it is set higher, it is possible to notify the player that the probability that the winning device changes from the second state to the first state is high by displaying the effect. Thereby, the player can prepare for the timing at which the winning device changes from the second state to the first state. This makes it possible to continue to be interested in the selected performance.

[First embodiment]
FIG. 1 is a front view showing a pachinko machine 1. A liquid crystal display device 4 that constitutes display means for variably displaying a plurality of special symbols is arranged at the approximate center of the game area (game board) 3 provided in the pachinko machine 1. The liquid crystal display device 4 performs variable display of a plurality of symbols (for example, three columns of left, center, and right) represented by an image. The special symbol displayed on the liquid crystal display device 4 starts to be displayed in a variable manner when a game ball wins a start winning opening 6 described later. When the combination of the three special symbols displayed in a stopped state becomes, for example, “7-7-7”, a transition is made to a special gaming state (big hit) that is advantageous to the player. Hereinafter, the odd special symbols are referred to as “specific symbols”, and the even special symbols are referred to as “non-specific symbols”. Whether or not to shift to the special game state is determined by a main control circuit 74 (FIG. 4) described later.

  Also, in the embodiment, the probability of transition to the special gaming state changes after the special gaming state ends (so-called “probability fluctuation”) after the special gaming state is ended depending on the symbol combination that has caused the transition to the special gaming state. It has become. When the special gaming state is generated by the combination of “specific symbols”, the probability of the next transition to the special gaming state is “1/66”. On the other hand, in the case of “non-specific symbol”, the probability is “1/335”. Hereinafter, a gaming situation in which the probability of transition to the special gaming state is “1/66” is referred to as “probability variation state”, and a gaming situation in which the probability of transition to the special gaming state is “1/335” is “normal state”. That's it.

  Below the liquid crystal display device 4, an ordinary electric accessory 5 constituting a start winning opening (so-called start hole) 6 is provided. The ordinary electric accessory 5 has a first state (hereinafter referred to as “open state”) that is easy to win the start winning opening 6 and a second state (hereinafter referred to as “closed state”) that is difficult to win the start winning opening 6. A winning device (so-called tulip) having an open / close blade that can be changed (for example, converted, transferred, or changed). As will be described later, the ordinary electric accessory 5 wins the ordinary symbol that is “winning”, and when the ordinary symbol variation time (FIG. 2) elapses, the ordinary electric accessory 5 changes to the open state. Even when the open / close wing piece is closed, about one game ball (pachinko ball) can be won. When the game ball wins the start winning opening 6, five prize balls are paid out. As will be described later, the time during which the ordinary electric accessory 5 can be kept open is 0.3 seconds in the probability variation state and 0.3 seconds in the normal state. The ordinary electric accessory 5 is changed to a closed state when one game ball is won. Hereinafter, an average until the game ball reaches the position of the ordinary electric accessory 5 through the left side of the liquid crystal display device 4 after the launch request sensor 61a described later (FIG. 4) detects the operation of the launch handle (not shown). Time is called “arrival time”. This “arrival time” is an average of actual measurement values, and is 3.5 seconds in the embodiment.

  A normal symbol operating gate 7 is provided above and to the left and right of the start winning opening 6. A gate switch 70 described later (FIG. 4) for detecting the passage of the game ball is provided inside the normal symbol operating gate 7.

  Below the ordinary electric accessory 5, there is provided a special winning opening (so-called attacker) 8 that can be converted into a first state advantageous to the player and a second state unfavorable to the player. When a game ball enters the attacker 8, a predetermined number (for example, 15) of prize balls are paid out. Below the grand prize winning port 8, an out port 9 for collecting out balls is provided. In the special game state, the special winning opening 8 is opened a predetermined number of times (for example, “15 times”). In the normal gaming state described later, the special winning opening 8 is kept closed.

  A rail 11 is installed on the left side of the game area 3. A game ball launched from the launching device 103 (FIG. 4 to be described later) moves up along the rail 11 and is driven into the game area 3.

  A 7-segment LED display device 10 is provided above the liquid crystal display device 4. The LED display device 10 starts the variable display for the numbers “0” to “9” when the game ball passes through the normal symbol operating gate 7 in the game area 3. When the fluctuation display of the LED display device 10 is stopped at a predetermined number (in the embodiment, “7”, and the stop mode of this number is referred to as “hit”), the ordinary electric accessory 5 is Converted to a state. With numbers other than “7” (in the embodiment, “0” to “6”, “8”, “9”, and the stop mode of these numbers is referred to as “losing”), the ordinary electric accessory 5 is It is not converted to the first state. Hereinafter, these numbers are referred to as “ordinary symbols”. Also, the time from when the normal symbol starts to change (starts to change) to when it stops (to end the change) is called “normal symbol change time”.

  As will be described later, there are a plurality of patterns in the normal symbol variation display. These patterns perform effects such as notifying the player of the probability of conversion to the first state and the firing start timing by changing the speed of the variable display. Hereinafter, a pattern for performing these effects is referred to as an “effect pattern”. Here, the firing start timing is an operation timing of a launching handle (not shown) at which the game ball can reach the position of the ordinary electric accessory 5 when the ordinary electric accessory 5 changes from the closed state to the open state. . Therefore, the notification of the timing is performed at a time before “arrival time” before the time when the ordinary electric accessory 5 is in the open state. Since the player can launch the game ball only at a timing at which the game ball can reach the position of the normal electric accessory 5 when the normal electric accessory 5 is in the open state, the game ball is not reduced. The game can be advanced (may increase).

  Hereinafter, the time from when the change of the normal symbol stops until the normal electric accessory 5 changes to the open state is referred to as “display time after determining the normal symbol (0.5 seconds in the embodiment)”. The time when is in the open state is referred to as “normal electric accessory opening time”.

  As shown in FIG. 2, the normal symbol variation time is 5 seconds in the probability variation state and 50 seconds in the normal state. The normal electric accessory opening time is 3 seconds in the probability variation state, and 0.3 seconds in the normal state.

  In FIG. 1 again, around the LED display device 10, four normal symbol memory LEDs 12 and special symbol memory LEDs 14a to 14d are provided. The normal symbol memory LED 12 is turned on one by one each time the game ball passes to the normal symbol operation gate 7, and the number of times the LED display device 10 can be changed at that time (up to four times) is played. To inform the person. The fifth and subsequent passes are not counted and are invalid. The special symbol storage LEDs 14a to 14d notify the player of the number of times that the special symbol can be variably displayed on the liquid crystal display device 4 at the present time.

  A windmill 18 is provided on the left side of the liquid crystal display device 4. A windmill 19 is provided on the right side of the liquid crystal display device 4. On the left and right sides of the start winning opening 6, there are provided general winning openings 31a, 31b, 31c, 31d which are determined so as to pay out 10 winning balls when there are winning balls, respectively.

  Next, the production pattern will be described with reference to FIG. 3 (1) to 3 (4) show an effect pattern of a normal symbol, and shows a temporal change from the variation display start (variation start) to the variation display end (variation end) of the normal symbol. As will be described later, the effect pattern shown in FIG. 3A is selected in the process of ST37 or ST41 of FIG. The effect pattern shown in FIG. 3B is selected only in the process of ST37 of FIG. The effect pattern shown in FIG. 3 (3) is selected in the process of ST47 or ST51 of FIG. The effect pattern shown in FIG. 3 (4) is selected only in the process of ST47 in FIG. In addition, the effect patterns shown in FIGS. 3A and 3B are selected in the normal state. The effect patterns shown in FIGS. 3 (3) and 3 (4) are selected in the probability variation state.

  In the effect pattern shown in FIG. 3 (1), the normal symbol is variably displayed at high speed from the start of change (0 seconds) to the end of change (50 seconds). Hereinafter, this effect pattern is referred to as “normal state high-speed fluctuation display effect”.

  In the production pattern shown in Fig. 3 (2), the normal symbol is displayed at a high speed from the start of change (0 seconds) to 47 seconds, and after 47 seconds, the display is changed at a low speed and displayed at 50 seconds. finish. The time (47 seconds) when the fluctuation display changes from high speed to low speed is a time point before “arrival time” before the time when the ordinary electric accessory 5 is opened. That is, this effect pattern is an effect pattern for informing “launch start timing”. Hereinafter, this effect pattern is referred to as “normal state low-speed fluctuation display effect”.

  In the effect pattern shown in FIG. 3 (3), the normal symbol is variably displayed at high speed from the start of change (0 seconds) to the end of change (5 seconds). Hereinafter, this effect pattern is referred to as a “high-speed change display effect for a probability change state”.

  In the production pattern shown in Fig. 3 (4), the normal symbol is displayed at a high speed from the start of the change (0 seconds) to 2 seconds, and after 2 seconds, the display is changed at a low speed and the display is changed at 5 seconds. finish. The time (2 seconds) when the fluctuation display changes from high speed to low speed is a time point before the “arrival time” before the time when the ordinary electric accessory 5 is opened. That is, this effect pattern is an effect pattern for informing “launch start timing”. Hereinafter, this effect pattern is referred to as “low-speed fluctuation display effect for the probability fluctuation state”.

  As described above, the effect patterns shown in FIGS. 3 (2) and 3 (4) are effect patterns for informing the “launch start timing”, and the player launches the game ball at the launch start timing. In addition, it is possible to win a prize for the ordinary electric accessory 5 and obtain a prize ball, to realize a special symbol change display, and to obtain an opportunity to shift to a special gaming state. Further, by stopping the launch of the game ball during a period other than the launch start timing, the game ball is fired at the timing when the game ball reaches the position of the normal motor combination 5 when the normal motor combination 5 is in the closed state. The inconvenience of doing can be avoided.

  FIG. 4 is a block diagram illustrating a configuration of an electric circuit unit of the pachinko machine 1.

  As shown in this figure, the pachinko machine 1 of the embodiment wins the gate switch 70 that detects the game ball that has passed through the normal symbol operating gate 7 and the general winning ports 31a, 31b, 31c, 31d. A general winning ball sensor 71 for detecting a game ball that has been won, a starting winning ball sensor 72 for detecting a gaming ball that has won a prize in the aforementioned starting winning hole 6, and a big winning prize for detecting a gaming ball that has won a prize in the aforementioned big winning hole 8 A ball sensor 73.

  The operation of the pachinko machine 1 is controlled by a main control circuit 74 constituting main control means disposed on the circuit board. The main control circuit 74 includes a central processing unit (CPU) 75 as a main component, and includes input / output ports (I / O ports) 76a and 76b serving as interfaces between the sensors and drive circuits described later. A ROM 77 as a read-only storage means and a RAM 78 as a readable / writable storage means are connected. As the RAM 78, a dynamic memory (DRAM) is used.

  Further, the main control circuit 74 generates a reset signal for executing the entire game control processing program periodically (for example, every 2 ms) (this is referred to as “interrupt generation”), a reset clock pulse generation circuit 79, And an initial reset circuit 81 for generating an initial reset signal for executing an initial process for the circuit when the power is turned on.

  The CPU 75 includes a jackpot determination random number counter 82, a jackpot symbol determination random number counter 83, a loss symbol determination random number counter 84, a variation pattern number determination random number counter 85, a normal symbol storage counter 86, and a normal symbol determination random number counter 87. The processing shown in FIGS. 8 to 11 described later is performed.

  The jackpot determination random number counter 82 is used to determine whether or not to shift to the special game state, and repeats addition at a predetermined time interval (here, every time an interrupt signal is generated), and is initialized at a constant period ( Reset to 0). The jackpot symbol determining random number counter 83 is used to determine three special symbols to be stopped and displayed when it is determined that the game state is shifted to the special gaming state (big jackpot). The random symbol counter for losing symbol determination 84 is used to determine three special symbols to be stopped and displayed when it is determined that the game state does not shift to the special gaming state. The variation pattern number determination random number counter 85 is used when determining the variation pattern number associated with the variation pattern of the special symbol.

  The normal symbol storage counter 86 stores the number of times the normal symbol including the currently changing symbol can be changed. Specifically, the detection signal from the gate switch 70 is counted up to “5” (ST22 in FIG. 10 described later). Further, the value of the normal symbol storage counter 86 is subtracted by “1” when the variation of the normal symbol is basically stopped. The normal symbol per-determination random number counter 87 is used to determine whether or not the normal symbol is won, that is, whether or not the normal electric accessory 5 is opened. Specifically, when “1” is added (counted) to the normal symbol storage counter 86, a random number is extracted from the normal symbol per-determination random number counter 87 (ST23 in FIG. 10 described later).

  The ROM 77 stores various tables shown in FIGS.

  The RAM 78 has a normal symbol storage area corresponding to the normal symbol storage counter 86. In the normal symbol storage area, the random value extracted from the normal symbol per-determination random number counter 87 is stored. Further, in a predetermined storage area of the RAM 78, a flag such as a normal symbol stop flag described later is set or cleared. Setting the flag means storing information indicating “1” in the storage area. Clearing the flag means storing information indicating “0” in the storage area.

  On the output side of the main control circuit 74, an LED display control circuit 90, a liquid crystal drive circuit 91, a sound control circuit 92 constituting sound control means, and a prize are arranged on a circuit board different from the circuit board on which the main control circuit 74 is arranged. The sphere control circuits 93 are connected as sub control circuits. Hereinafter, these sub-control circuits will be described. Each sub control circuit does not input a command or the like to the main control circuit 74, and communication is performed in one direction from the main control circuit 74 to the sub control circuit side.

  (1) The LED display control circuit 90 controls the operation of the LED display device 10 and the normal symbol memory LED 12 based on the effect command transmitted from the main control circuit 74. The effect command includes information on the effect pattern determined by the CPU 75.

  (2) The liquid crystal drive circuit 91 includes an MPU, a program ROM, an image ROM, a work RAM, a VDP (Video Display Processor), a CTC (Count Timer Controller), and the like, and is based on a command from the main control circuit 74. 4 is driven. In this embodiment, the command transmitted from the main control circuit 74 to the LED display control circuit 90 includes a “variable display pattern designation command” for designating a special symbol stop mode (stop symbol) and a variation pattern number, and a normal symbol described later. A hit flag is set to indicate that the normal symbol starts to change, and the normal symbol change command that includes information on the normal symbol change time, the normal symbol starts to change without the normal symbol per flag being set. There are “ordinary symbol loss change command”, “ordinary symbol confirmation command”, “ordinary symbol loss confirmation command”, and the like.

  (3) The sound control circuit 92 includes a CPU, a ROM, a RAM, a SOUND IC, and an AMP, and controls the sound output device 101 as a sound generation unit based on the output.

  (4) The command output from the main control circuit 74 and the detection signal of the firing request sensor 61a that detects the operation of the firing handle (not shown) are input to the prize ball control circuit 93. The prize ball control circuit 93 controls the payout device 102 for paying out the prize balls and the launching device 103 for launching the game balls to the game area 3 based on the command and the detection signal. The payout device 102 includes a payout ball sensor (not shown) that detects a payout ball, and a detection signal generated by the payout ball sensor is supplied to the prize ball control circuit 93. The ordinary electric accessory control circuit 104 and the special winning opening control circuit 105 of the main control circuit 74 control the ordinary electric combination 5 and the special winning opening 8.

  Next, the normal condition hit determination table will be described with reference to FIG. This table is used to determine whether or not to win a normal symbol in a normal state. Specifically, reference is made at ST36 of FIG. In this normal state hit determination table, when the random value set in the process of ST24 (FIG. 10) described later is a value within the range of “0” to “115”, it is “lost”. The probability of being determined as “losing” is 116/256. When the random number value is in the range of “116” to “255”, it is “winning (winning)”. The probability of being judged “win” is 140/256.

  Next, the probability variation state hit determination table will be described with reference to FIG. This table is used to determine whether or not to win a normal symbol in the probability variation state. Specifically, reference is made at ST46 in FIG. This probability variation state hit determination table is “lost” when the random number set in the processing of ST24 described later is a value within the range of “0” to “25”. The probability of being determined as “losing” is 26/256. When the random value is a value within the range of “26” to “255”, it is “hit”. The probability of being judged “win” is 230/256.

  Next, the winning effect selection table will be described with reference to FIG. This winning effect selection table is referred to in ST37 and ST47 of FIG. 11 described later when a normal symbol is won.

In the normal state, when the random number value extracted in the process of ST37 in FIG. 11 described later is a value within the range of “0” to “90”, the “normal state high-speed fluctuation display effect” is selected. When the random value is a value within a range of “91” to “255”, “normal state low-speed fluctuation display effect” is selected. The probability that the “normal state high-speed fluctuation display effect” is selected is 91/256, and the probability that the “normal state low-speed fluctuation display effect” is selected is 165/256. If the normal symbol is “lost”, the “normal state high-speed fluctuation display effect” is selected, and the “normal state low-speed fluctuation display effect” is not selected. Therefore, when the “normal state low-speed fluctuation display effect” is performed, the normal symbol is always “hit”. That is, the “normal state low-speed fluctuation display effect” indicates that the probability that the normal electric accessory 5 changes from the closed state to the open state is 100%.

  In the probability variation state, when the random number value extracted in the process of ST37 in FIG. 11 described later is a value within the range of “0” to “11”, “high-speed variation display effect for probability variation state” is selected. When the random value is a value in the range of “12” to “255”, “slow fluctuation display effect for probability fluctuation state” is selected. The probability that the “high-speed variation display effect for the probability variation state” is selected is 12/256, and the probability that the “low-speed variation display effect for the probability variation state” is selected is 244/256. In this case, when the normal symbol is “lost”, the “probability variation state high-speed variation display effect” is selected, and the “probability variation state low-speed variation display effect” is not selected. Therefore, when the “low-speed fluctuation display effect for probability fluctuation state” is performed, the normal symbol is always “hit”. That is, the “low-speed fluctuation display effect for probability fluctuation state” indicates that the probability that the ordinary electric accessory 5 changes from the closed state to the open state is 100%.

  Here, according to the normal state hit determination table shown in FIG. 5, when the normal symbol variation display is performed 256 times, the number of times that the normal symbol is “win (win)” is “140 times”. The number of times of “losing” is “116 times”. According to the winning effect selection table shown in FIG. 7, the “normal state high-speed fluctuating display effect” is selected from “140 times” as “winning”, “approximately 50 times (≈140 × 91). / 256) ". That is, among the 256 normal symbol fluctuation displays, the “normal state high-speed fluctuation display effect” is performed “166 times (116 + 50)”. Of the “166 times”, “50 times” is “winning” in the normal symbol. That is, the “normal state high-speed fluctuation display effect” indicates that the probability that the ordinary electric accessory 5 changes from the closed state to the open state is about 30% (≈50 / 166).

  In the normal state, the production patterns selected when “win” is “normal state high-speed fluctuation display effect” and “normal state low-speed fluctuation display effect”, and “normal state high-speed fluctuation display effect” Then, since it is notified that the probability that the ordinary electric accessory 5 changes from the closed state to the open state is as low as 30%, for example, the player sees “high-speed fluctuation display effect for normal state” as “losing” If you think it is, you will be surprised at the outcome of the game. That is, it is possible to give the player an unexpected game. The “normal state low-speed fluctuation display effect” is an effect pattern that is selected only when it is surely “winning”, and when this effect pattern is displayed, the player must always close the ordinary electric accessory 5. Can be seen to change from open to open.

  Further, according to the probability variation state hit determination table shown in FIG. 6, when the fluctuation display of the normal symbol is performed 256 times, the number of times “winning (winning)” for the normal symbol is “230”. The number of times of “losing” is “26 times”. According to the winning effect selection table shown in FIG. 7, among “230 times” as “winning”, the “high-speed fluctuation display effect for the probability variation state” is selected as “about 11 times (≈230 × 12/256) ". That is, among the 256 normal symbol fluctuation displays, the “probability fluctuation state high-speed fluctuation display effect” is performed “37 times (26 + 11)”. Of the “37 times”, the “success” is “11 times” for the normal symbol. That is, the “high-speed fluctuation display effect for the probability fluctuation state” indicates that the probability that the ordinary electric accessory 5 changes from the closed state to the open state is about 30% (≈11 / 37).

  In the probability variation state, the production patterns to be selected when “win” is “high-speed variation display effect for probability variation state” and “low-speed variation display effect for probability variation state”, and “high-speed variation for probability variation state” The “display effect” notifies that the probability that the ordinary electric accessory 5 changes from the closed state to the open state is as low as 30%. For example, the player performs the “high-speed change display effect for the probability change state”. If you see it as “losing”, you will be surprised at the result of the game. That is, it is possible to give the player an unexpected game. The “low-speed fluctuation display effect for the probability variation state” is an effect pattern that is selected only when it is surely “winning”, and when this effect pattern is displayed, the player always closes the ordinary electric accessory 5. You can see the transition from the state to the open state.

  As described above, the effect patterns shown in FIGS. 12 (2), (3), (5), and (6) are effect patterns for informing the “launch start timing”, and the player plays the game at the launch start timing. By firing the ball, it is possible to win a prize for the ordinary electric accessory 5 and obtain a prize ball, to realize a special symbol variation display, and to obtain an opportunity to shift to the special gaming state. Further, by stopping the launch of the game ball during a period other than the launch start timing, the game ball is fired at the timing when the game ball reaches the position of the normal motor combination 5 when the normal motor combination 5 is in the closed state. The inconvenience of doing can be avoided.

  Next, the normal state effect selection table shown in FIG. 13 will be described. The normal state effect selection table shown in FIG. 13 is referred to in ST66 described later. When the random number set in the process of ST24 (FIG. 10) is a value within the range of “0” to “130”, “normal state high-speed fluctuation display effect” is selected. When the random value is a value within the range of “131” to “211”, “medium speed fluctuation display effect for normal state” is selected. When the random value is a value within the range of “212” to “255”, “low-speed fluctuation display effect for normal state” is selected.

When the random value is a value within the range of “20” to “69”, “medium speed variation display effect for probability variation state” is selected. When the random value is a value in the range of “70” to “255”, “slow fluctuation display effect for probability fluctuation state” is selected.

  The probability that the “high-speed fluctuation display effect for the probability fluctuation state” will be selected is 20/256, the probability that the “medium speed fluctuation display effect for the probability fluctuation state” will be 50/256, The probability that the “low-speed fluctuation display effect” is selected is 186/256.

  FIG. 15 is a hit determination table that is referred to in the processes of ST69 and ST76 described later.

  The hit determination table shown in FIG. 15 (1) is referred to in the process of ST69 (FIG. 16) described later when “normal state high-speed fluctuation display effect” is selected in the process of ST66 (FIG. 16) described later. When “high-speed fluctuation display effect for probability fluctuation state” is selected in the process of ST73 (FIG. 16) described later, the process is referred to in the process of ST76 (FIG. 16) described later. When the random number value extracted in the process of ST69 is a value within the range of “0” to “178”, it is determined as “lost”, and when the random number value is within the range of “179” to “255”, Is determined. Further, “high-speed fluctuation display effect for probability fluctuation state” is determined to be “lost” when the random number value extracted in the process of ST76 (FIG. 16) described later is a value within the range of “0” to “178”. When the value is in the range of “179” to “255”, it is determined as “winning”.

  The “normal state high-speed change display effect” and the “probability change state high-speed change display effect” are obtained when the random number extracted as described above is a value within the range of “179” to “255”. Is determined. Therefore, these performance patterns indicate that the probability that the ordinary electric accessory 5 changes from the closed state to the open state is about 30% (≈77 / 256). Since the “normal state high-speed fluctuation display effect” and the “probability fluctuation state high-speed fluctuation display effect” notify that the probability that the normal electric accessory 5 changes from the closed state to the open state is as low as 30%. For example, if a player sees “high-speed fluctuation display effect for normal state” and thinks that he / she is “lost”, he / she feels unexpectedness in the result of the game. That is, it is possible to give the player an unexpected game.

  The hit determination table shown in FIG. 15 (2) is referred to in the process of ST69 described later when “medium speed fluctuation display effect for normal state” is selected in the process of ST66 described later. When the “medium speed fluctuation display effect for probability fluctuation state” is selected, it is referred to in the process of ST76 described later. “Medium speed fluctuation display effect for normal state” is determined as “lost” when the random number value extracted in the process of ST69 is a value within the range of “0” to “76”, and “77” to “255”. When the value is within the range of “”, it is determined to be “hit”. The “medium-speed fluctuation display effect for probability fluctuation state” is determined as “losing” when the random number value extracted in the process of ST76 is a value within the range of “0” to “76”, and “77”. When the value is within the range of “255”, it is determined as “win”.

  The “medium speed fluctuation display effect for normal state” and the “medium speed fluctuation display effect for probability change state” indicate that when the extracted random number value is a value within the range of “77” to “255”, “High-speed fluctuation display effect” is determined to be “winning”. Therefore, these performance patterns indicate that the probability that the ordinary electric accessory 5 changes from the closed state to the open state is about 70% (≈179 / 256). Since it is informed that the probability that the ordinary electric accessory 5 changes from the closed state to the open state is 70%, for example, the player sees “medium speed fluctuation display effect for normal state” and hits “ If you thought it was, it would be surprising if you were losing. That is, it is possible to give the player an unexpected game.

  Next, normal symbol processing will be described with reference to FIG. In this normal symbol processing, the LED display control circuit 90 is controlled based on the random value set in the normal symbol storage area of the RAM 78, and a command related to the normal symbol variation display is transmitted to the liquid crystal drive circuit 91. I do.

  First, the CPU 75 determines whether or not a random value is set in the process of ST24 (ST61). When this determination is “YES”, the process proceeds to ST62, and when “NO”, the process waits until a random value is set. In the process of ST62, it is determined whether or not the normal symbol variation display is finished. If this determination is “YES”, the process proceeds to ST63, and if “NO”, the process returns to the beginning.

  In the process of ST63, it is determined whether or not the state is a probability variation state. If this determination is “YES”, the process proceeds to ST71, and if “NO”, the process proceeds to ST64.

  The process of ST64 selects the normal state effect selection table (FIG. 13) that is referred to in the process of ST66 described later. Next, a process for setting the normal symbol variation time to 50 seconds is performed (ST65), and the process proceeds to ST66.

  In the process of ST66, an effect pattern is selected with reference to the normal state effect selection table (FIG. 13). Next, effect commands to be transmitted to the liquid crystal drive circuit 91 are generated (ST67), and these effect commands are stored in the RAM 78 (ST68).

  In the process of ST69, it is determined whether or not to “win” based on the effect pattern selected in the process of ST66. When “normal state high-speed fluctuation display effect” and “normal state medium-speed fluctuation display effect” are selected, a random number is extracted, and a hit determination table (FIG. 15) is referred to determine whether or not a win. judge. When this determination is “YES”, the process proceeds to ST70, and when “NO”, the process proceeds to ST61. If “normal state low-speed fluctuation display effect” is selected in the process of ST66, it is determined as “winning”, and the process proceeds to ST70.

  In the process of ST70, based on the effect command stored in the process of ST68, the control process of the ordinary electric accessory 5 is performed, and the process returns to ST61.

  In the process of ST71, an effect selection table for probability variation state (FIG. 14) to be referred to in the process of ST73 described later is selected. Next, a process for setting the normal symbol variation time to 5 seconds is performed (ST72), and the process proceeds to ST73.

  In the process of ST76, it is determined whether or not to “win” based on the effect pattern selected in the process of ST73. If “high-speed fluctuation display effect for probability variation state” and “medium-speed fluctuation display effect for probability variation state” are selected, a random number value is extracted, and a hit determination table (FIG. 15) is referenced to determine whether or not Determine whether. When this determination is “YES”, the process proceeds to ST77, and when “NO”, the process proceeds to ST61. When “low-speed fluctuation display effect for probability fluctuation state” is selected in the process of ST73, it is determined as “winning” and the process proceeds to ST77.

  In the process of ST77, based on the effect command stored in the process of ST75, the normal electric accessory 5 is controlled, and the process returns to ST61.

  In the embodiment, it is set as described above, but the present invention is not limited to this, and the random number range can be set freely.

  Further, “win” is set to “7”, but any symbol other than “7” may be set. A plurality of “winning” symbols may be set.

  Further, although the ordinary electric accessory 5 is employed as the winning device, the present invention is not limited to this. For example, it is possible to employ any winning device such as the big winning port 8, the general winning ports 31a, 31b, 31c, 31d.

  Further, although the normal symbol operation gate 7 is employed as a trigger for the normal symbol variation display, any winning device as described above can be employed. In addition to these winning devices that are detected from the game ball, the time-varying display may be started.

  Further, the time until the ordinary electric accessory 5 changes to the open state after the normal symbol starts to fluctuate in each of the probability variation state and the normal state is not limited to this. For example, the time can be changed by a random value or the like. In addition, when the special winning opening 8 is adopted as the winning device, in the special gaming state, after the special winning opening 8 changes from the first state (open state) to the second state (closed state), the first It is also possible to change the time until the transition to the state according to the random number lottery result or the like. The number of game balls acquired in the special game state changes depending on the presence / absence of notification such as the start timing of the launch, which increases the fun of the game. In addition, it is preferable that the total opening time (total time in the open state) of the grand prize winning opening 8 triggered by the big hit is constant.

  In the embodiment, the game ball can win even when the ordinary electric accessory 5 which is an example of the winning device is in the second state (closed state), but the present invention is not limited to this. For example, a state where there is no winning probability of a game ball can be adopted as the second state. In addition, the ordinary electric accessory 5 can be converted into two stages of an open state and a closed state, but when adopting a winning device that can be converted into three or more stages having different ease of winning, either Two stages may be employed as the first state and the second state.

  Further, in the embodiment, “the fact that a predetermined number of game balls were won during opening” is adopted as one of the conditions for the ordinary electric accessory 5 to change to the closed state, but this condition is not adopted. It may be.

  Further, in the embodiment, the average time until the game ball reaches the position of the ordinary electric accessory 5 through the left side of the liquid crystal display device 4 is adopted as the “arrival time”, but is not limited to this. Absent. As the “arrival time”, an average time until the game ball reaches the position of the ordinary electric accessory 5 through the right path of the liquid crystal display device 4 and other arbitrary paths can be adopted. In addition, for each path along which the game ball reaches the position of the ordinary electric accessory 5, it is possible to notify the firing start timing. In addition, the player can select the route in advance, and can make a notification at a timing according to the route.

  In the embodiment, the LED display device 10 is employed as the notification unit, but the present invention is not limited to this. An operating object such as a mechanical reel or a model (so-called “act”), a speaker, a light emitting unit, a liquid crystal display device, or the like may be used.
