In the special symbol display 81, the special symbol is variably displayed (variable display) and then stopped, so that the lottery based on the winning of the first starting port 11 or the second starting port 12 (special symbol lottery, big hit lottery) can be performed. Notify the result. The stop-displayed special symbol (stop symbol, special symbol derived and displayed as a display result of variable display) is one special symbol selected from a plurality of types of special symbols by a special symbol lottery. When the stop symbol is a predetermined special symbol (special symbol of a specific stop mode, that is, a jackpot symbol), the opening pattern is set according to the type of the specific special symbol that is stopped and displayed (that is, the type of the winning jackpot). A jackpot game (an example of a special game) that opens the big winning opening 14 is performed. The opening pattern of the big winning opening in the special game will be described later.

Specifically, the special figure display 81 is composed of, for example, eight LEDs (Light Emitting Diodes) arranged side by side, and displays a special symbol according to the result of the jackpot lottery depending on the lighting mode thereof. be. For example, if you win a jackpot (one of the multiple types of jackpots described below), you will see "○○ ●● ○○ ●●" (○: lit, ●: off) from the left 1, 2, The jackpot symbol with the 5th and 6th LEDs lit is displayed. If there is a loss, a lost pattern such as "●●●●●●● ○" is displayed, in which only the LED on the far right is lit. A mode in which all the LEDs are turned off may be adopted as a lost pattern. The lost symbol is not a specific special symbol. Further, before the special symbol is stopped and displayed, the fluctuation display of the special symbol is performed over a predetermined fluctuation time, and the mode of the fluctuation display is, for example, each LED is lit so that light repeatedly flows from left to right. This is the aspect. It should be noted that the variable display mode may be any mode such that all the LEDs blink at the same time unless each LED is stopped display (lighting display in a specific mode).

In this pachinko gaming machine PY1, if there is a winning (winning) of a game ball in the first starting port 11 or the second starting port 12, the value of various random numbers such as the jackpot random number acquired for the winning (numerical information). , The determination information) is temporarily stored in the special figure reservation storage unit 105 described later. Specifically, if a prize is won in the first starting port 11, it is stored in the first special figure holding storage unit 105a, which will be described later, as a first special figure hold, and if a prize is won in the second starting port 12, the second special figure is held. As a figure hold, it is stored in the second special figure hold storage unit 105b described later. There is an upper limit to the number of special figure reservations that can be stored in each special figure reservation storage unit 105, and the upper limit value in this embodiment is "4", respectively.

The special figure hold stored in the special figure hold storage unit 105 is digested when the special symbol can be variably displayed based on the special figure hold. The digestion of the special figure hold means that the jackpot random number or the like corresponding to the special figure hold is determined, and the variable display of the special symbol for showing the determination result is executed. Therefore, in the pachinko gaming machine PY1, when the variable display of the special symbol based on the winning of the game ball to the first starting port 11 or the second starting port 12 cannot be performed immediately after the winning, that is, the variable display of the special symbol is executed. Even if a prize is won during the middle or special game, the right to the jackpot lottery for the prize can be reserved up to a predetermined number.

The number of such special figure hold is displayed on the special figure hold indicator 83. Specifically, each of the special figure hold display 83 is composed of, for example, four LEDs, and displays the number of special figure hold by turning on the LEDs as many as the number of special figure hold.

The variable display of the normal symbol is performed when the game ball passes through the gate 13. The normal symbol display 82 notifies the result of the normal symbol lottery based on the passage of the game ball to the gate 13 by displaying the normal symbol in a variable manner (variable display) and then stopping the display. The normal symbol that is stopped and displayed (normal symbol, normal symbol that is derived and displayed as a display result of variable display) is one ordinary symbol selected from a plurality of types of ordinary symbols by the ordinary symbol lottery. When the stop-displayed normal symbol is a predetermined specific normal symbol (ordinary symbol in a predetermined stop mode, that is, a normal hit symbol), the second start opening 12 is opened with an opening pattern according to the current gaming state. Auxiliary games are played. The opening pattern of the second starting port 12 will be described later.

Specifically, the normal symbol display 82 is composed of, for example, two LEDs (see FIG. 5), and displays a normal symbol according to the result of a normal symbol lottery depending on the lighting mode thereof. For example, when the lottery result is a win, a normal hit symbol in which both LEDs are lit is displayed, such as "○○" (○: on, ●: off). If the lottery result is lost, a normal lost symbol such as "● ○" in which only the right LED is lit is displayed. A mode in which all the LEDs are turned off may be adopted as a normal loss pattern. It should be noted that the normal loss symbol is not a specific normal symbol. Before the normal symbol is stopped and displayed, the fluctuation display of the normal symbol is performed over a predetermined fluctuation time, and the mode of the fluctuation display is, for example, that both LEDs are turned on alternately. It should be noted that the variable display mode may be any mode such that all the LEDs blink at the same time unless each LED is stopped display (lighting display in a specific mode).

In this pachinko gaming machine PY1, when a game ball passes through the gate 13, the value of the normal symbol random number (hit random number) acquired for the passage is stored in the normal figure hold storage unit 106 described later as a normal figure hold. It will be memorized once. There is an upper limit to the number of normal figure reservations that can be stored in the normal figure hold storage unit 106, and the upper limit value in this embodiment is "4".

The normal figure hold stored in the normal figure hold storage unit 106 is digested when the variable display of the normal symbol based on the normal figure hold becomes possible. The digestion of the normal symbol hold means to determine a normal symbol random number (hit random number) corresponding to the normal symbol hold and execute variable display of the normal symbol to show the determination result. Therefore, in this pachinko gaming machine PY1, if the variable display of the normal symbol based on the passage of the game ball to the gate 13 cannot be performed immediately after the passage, that is, the prize is won during the execution of the variable display of the normal symbol or the execution of the auxiliary game. Even if there is, it is possible to reserve the right of the ordinary symbol lottery for the passage up to a predetermined number.

Then, the number of such a normal figure hold is displayed on the normal figure hold indicator 84. Specifically, the normal figure hold display 84 is composed of, for example, four LEDs, and displays the number of normal figure hold by turning on the LEDs as many as the number of normal figure hold.

The game ball to be paid out is detected by the prize ball sensor 73a for counting, and the detection signal by the prize ball sensor 73a is output to the payout control board 170.

When the player operates the handle 72k (see FIG. 1) of the launching device 72, the touch switch 72a detects contact with the handle 72k, and the firing volume 72b detects the amount of rotation of the handle 72k. Then, the launch solenoid 72s is driven so that the game ball is launched with a strength corresponding to the magnitude of the detection signal of the launch volume 72b. In this pachinko gaming machine PY1, one gaming ball is launched in about 0.6 seconds.

Further, the game control board 100 transmits various commands to the effect control board 120. The connection between the game control board 100 and the effect control board 120 is a unidirectional communication connection capable of only transmitting a signal from the game control board 100 to the effect control board 120. That is, a unidirectional circuit (for example, a circuit using a diode) (not shown) as a communication direction regulating means is interposed between the game control board 100 and the effect control board 120.

The effect control microcomputer 121 outputs voice, music, sound effects, and the like from the speaker 620 via the voice CPU 149 of the image control board 140 based on the command received from the game control board 100. The voice CPU 149 controls the voice of the speaker 620 via the voice control circuit 150 based on a command from the image CPU 141. Acoustic data such as voice output from the speaker 620 is stored in the effect ROM 123 of the effect control board 120. However, the acoustic data may be stored in the image ROM 142 of the image control board 140.

Although the image control board 140 is made to perform voice control of the speaker 620, a voice control board may be provided separately from the image control board 140, and the voice control board may be made to perform voice control of the speaker 620. In this case, the voice control board may be connected to the effect control board 120, or may be connected to the effect control board 120 via the image control board 140.

Except for the game control board 100, any plurality of boards shown in FIGS. 6 and 7 may be configured as one board, or one board shown in FIGS. 6 and 7 may be configured as a plurality of boards. good.

3. 3. Explanation of jackpots, etc. In the pachinko gaming machine PY1 of this embodiment, there are "big hits" and "missing" as a result of the jackpot lottery (special symbol lottery). At the time of "big hit", the "big hit symbol" is stopped and displayed on the special figure display 81. At the time of "off", the "missing symbol" is stopped and displayed on the special figure display 81. When the jackpot is won, a "big hit game" is executed in which the jackpot 14 is opened in an opening pattern according to the type of special symbol (type of jackpot) that is stopped and displayed. The jackpot game is also called a special game.

In this form, the jackpot game consists of multiple round games (unit open game), an opening before the first round game is started (also referred to as OP), and an ending after the final round game is completed. (Also referred to as ED) and is included. Each round game begins with the end of the OP or the end of the previous round game and ends with the start of the next round game or the start of the ED. The closing time (interval time) of the large winning opening between round games is included in the open round game before the closing.

There are multiple types of jackpots. The types of jackpots are as shown in FIG. As shown in FIG. 8, there are roughly two types in this embodiment. Probability change jackpot and normal jackpot. The probabilistic jackpot is a jackpot that controls the gaming state after the jackpot game to a high probability state described later. The normal jackpot is a jackpot that controls the gaming state after the jackpot game to the normal probability state (low probability state) described later.

More specifically, for the probabilistic jackpot and the normal jackpot that can be won in the lottery of special figure 1 (lottery of the first special symbol), the big winning opening 14 is opened for a maximum of 29.5 seconds per 1R from 1R to 8R. However, from 9R to 16R, it is a big hit that opens the big winning opening 14 for a maximum of 0.1 seconds per 1R. That is, although the total number of rounds of these jackpots is 16R, the actual number of rounds is 8R. The actual number of rounds is the number of rounds in which a game ball can win up to the maximum number of winnings per round (8 in this embodiment). In these big hits, from 9R to 16R, the opening time of the big winning opening 14 is extremely short, and it is a round in which no prize ball can be expected. If the "probability change jackpot" is won by the lottery of the special figure 1, the "special figure 1_probability variation symbol" is stopped and displayed on the first special figure display 81a, and if the "normal jackpot" is won, the "normal figure 1_probability change symbol" is stopped and displayed. "Special figure 1_normal symbol" is stopped and displayed on the first special figure display 81a.

In addition, the probabilistic jackpot and the normal jackpot that can be won in the lottery of the special figure 2 (the lottery of the second special symbol) are jackpots that open the big winning opening 14 from 1R to 16R for a maximum of 29.5 seconds per 1R. In other words, these jackpots have a substantial number of rounds of 16R. If the "probability change jackpot" is won by the lottery of the special figure 2, the "special figure 2_probability variation symbol" is stopped and displayed on the second special figure display 81b, and if the "normal jackpot" is won, the second "Special figure 2_normal symbol" is stopped and displayed on the special figure display 81b.

Regardless of which jackpot is won, it is controlled to the electric support control state (high base state) described later after the jackpot game. If the electric support control state is controlled according to the high probability state, it continues until the next big hit winning. On the other hand, when the control is performed in association with the normal probability state (low probability state), the number of electric support times (time reduction number) is set to 100 times. The number of times of electric support is the upper limit of the number of times of execution of the fluctuation display of the special symbol in the electric support control state.

As shown in FIG. 8, the jackpot distribution rate in the lottery of Special Figure 1 and the lottery of Special Figure 2 is 65% for the probabilistic jackpot and 35% for the normal jackpot. However, if the jackpot is won based on the lottery of Special Figure 1, the jackpot game with an actual number of rounds of 8 is executed, while if the jackpot is won based on the lottery of Special Figure 2, the actual number of rounds is 8 rounds. The lottery of the special figure 2 is set to be more advantageous to the player than the lottery of the special figure 1 in that the jackpot game with 16 rounds is executed.

Here, in the pachinko gaming machine PY1, the lottery for whether or not the jackpot is a big hit is performed based on the "big hit random number", and the lottery for the winning jackpot type is performed based on the "winning type random number". As shown in FIG. 9A, the jackpot random number takes a value in the range of 0 to 65535. The hit type random number takes a value in the range of 0 to 99. The random numbers acquired based on the winning of the first starting port 11 or the second starting port 12 include "reach random numbers" and "variable pattern random numbers" in addition to the jackpot random numbers and the hit type random numbers.

The reach random number is a random number that determines whether or not to generate reach in the effect symbol variation effect indicating the result when the result of the jackpot determination is out of order. Reach is a state in which there is only one effect symbol EZ that is variablely displayed among a plurality of effect symbol EZs, and it depends on which symbol the variable display effect symbol EZ is stopped and displayed. It is a state (for example, a state of "7 ↓ 7") in which a combination of effect symbols EZ indicating a big hit is won. The effect symbol EZ that is stopped and displayed in the reach state may be displayed as if it is slightly shaken in the display screen 50a, or may be displayed so as to be repeatedly enlarged and reduced. This reach random number takes a value in the range of 0 to 255.

Further, the fluctuation pattern random number is a random number for determining the fluctuation pattern including the fluctuation time. The variation pattern random number takes a value in the range of 0 to 99. Further, the random numbers acquired based on the passage to the gate 13 include ordinary symbol random numbers (hit random numbers) shown in FIG. 9B. The ordinary symbol random number is a random number for a lottery (ordinary symbol lottery) as to whether or not to perform an auxiliary game for opening the electric chew 12D. Ordinary symbol random numbers take a value in the range of 0 to 65535.

4. Description of the gaming state Next, the gaming state of the pachinko gaming machine PY1 of the present embodiment will be described. The special figure display 81 and the normal figure display 82 of the pachinko gaming machine PY1 have a probability fluctuation function and a fluctuation time shortening function, respectively. The state in which the probability fluctuation function of the special figure display 81 is operating is referred to as a "high probability state", and the state in which the probability fluctuation function is not operating is referred to as a "normal probability state (non-high probability state)". In the high probability state, the jackpot probability is higher than in the normal probability state. That is, the jackpot determination is performed using a jackpot determination table in which the value of the jackpot random number determined to be a jackpot is larger than the jackpot determination table used in the normal probability state (see FIG. 10A). That is, when the probability fluctuation function of the special symbol display 81 is activated, the probability that the display result (that is, the stop symbol) of the variable display of the special symbol by the special symbol display 81 becomes a jackpot symbol as compared with the case where it is not activated. Will be higher.

Further, the state in which the fluctuation time shortening function of the special figure display 81 is operating is referred to as a "time saving state", and the state in which the special figure display 81 is not operating is referred to as a "non-time saving state". In the time-reduced state, the fluctuation time of the special symbol (time from the start of the fluctuation display to the derivation display of the display result) is shorter than in the non-time-reduced state. That is, the fluctuation pattern is determined using the fluctuation pattern table in which the fluctuation pattern having a short fluctuation time is selected more often than in the non-time reduction state (see FIG. 11). That is, when the variable time shortening function of the special symbol display 81 is activated, it becomes easier to select a short variable time as the variable time of the variable display of the special symbol as compared with the case where the special symbol display 81 is not activated. As a result, in the time-saving state, the pace of digestion of the special figure hold becomes faster, and an effective prize (a prize that can be memorized as the special figure hold) to the starting port is likely to occur. Therefore, it is possible to aim for a big hit with the smooth progress of the game.

The probability fluctuation function and the fluctuation time shortening function of the special figure display 81 may be operated at the same time, or only one of them may be operated. The probability fluctuation function and the fluctuation time shortening function of the normal figure display 82 are operated in synchronization with the fluctuation time shortening function of the special figure display 81. That is, the probability fluctuation function and the fluctuation time shortening function of the normal figure display 82 operate in the time saving state and do not operate in the non-time saving state. Therefore, in the time-saving state, the winning probability in the normal symbol lottery is higher than in the non-time-saving state. That is, the hit judgment (judgment of the normal symbol) is performed using the normal symbol hit judgment table in which the value of the normal symbol random number (hit random number) judged to be a hit is larger than the normal symbol hit judgment table used in the non-time saving state (judgment of the normal symbol). See FIG. 10 (C)). That is, when the probability fluctuation function of the normal figure display 82 is activated, the probability that the display result of the variable display of the normal symbol by the normal figure display 82 becomes a normal hit symbol is higher than when it is not activated. ..

Also, in the time-saving state, the fluctuation time of the normal symbol is shorter than in the non-time-saving state. In this embodiment, the fluctuation time of the normal symbol is 7 seconds in the non-time saving state, but 1 second in the time saving state (see FIG. 10 (D)). Further, in the time saving state, the opening time of the electric chew 12D in the auxiliary game is longer than in the non-time saving state (see FIG. 12). That is, the opening time extension function of the electric chew 12D is operating. In addition, in the time saving state, the number of times the electric chew 12D is opened in the auxiliary game is larger than in the non-time saving state (see FIG. 12). That is, the function of increasing the number of times of opening of the electric chew 12D is operating.

In the situation where the probability fluctuation function and the fluctuation time shortening function of the normal figure display 82, and the opening time extending function and the opening number of times increasing function of the electric chew 12D are operating, compared with the case where these functions are not operating. Therefore, the electric chew 12D is frequently opened, and the game ball frequently wins a prize at the second starting port 12. As a result, the base, which is the ratio of the number of prize balls to the number of fired balls, becomes high. Therefore, the state in which these functions are operating is referred to as a "high base state", and the state in which these functions are not operating is referred to as a "low base state". In the high base state, you can aim for a big hit without significantly reducing the number of game balls you have. The high base state is a state in which so-called electric support control (control for supporting winning of the second starting port 12 by the electric chew 12D) is being executed. Therefore, the high base state is also referred to as an electric support control state or a ball entry easy state. On the other hand, the low base state is also called a non-electric support control state or a non-ball entry easy state.

The high base state does not have to activate all of the above functions. That is, the operation of one or more of the probability fluctuation function of the normal figure display 82, the fluctuation time shortening function of the normal figure display 82, the opening time extension function of the electric chew 12D, and the opening frequency increasing function of the electric chew 12D. It suffices if the electric chew 12D is easier to open than when the function is not operating. Further, the high base state may be controlled independently without being accompanied by the time saving state.

In the pachinko gaming machine PY1 of the present embodiment, the gaming state after the jackpot game by winning the probabilistic jackpot is a high probability state, a time saving state, and a high base state. This gaming state is particularly called a "high accuracy and high base state". The high-accuracy high-base state ends when the variable display of the special symbol is executed a predetermined number of times (10000 times in this embodiment), or when the jackpot is won and the jackpot game is executed. In other words, in this embodiment, the high accuracy and high base state is substantially continued until the next big hit. In addition, the end condition of the high accuracy and high base state may be only that the big hit is won and the big hit game is executed.

Further, the gaming state after the jackpot game by winning the normal jackpot is a normal probability state (non-high probability state, that is, a low probability state), a time saving state, and a high base state. This gaming state is particularly called a "low accuracy high base state". The low probability high base state ends when the variable display of the special symbol is executed a predetermined number of times (100 times in this embodiment), or when the jackpot is won and the jackpot game is executed.

When playing the pachinko gaming machine PY1 for the first time, the gaming state after the power is turned on is a normal probability state, a non-time saving state, and a low base state. This gaming state is particularly referred to as a "low probability low base state". The low probability low base state is referred to as a "normal gaming state". Further, the state in which the special game (big hit game) is being executed is referred to as a "special game state (big hit game state)". Further, a state controlled by at least one of a high probability state and a high base state is referred to as a "privilege gaming state".

In a high base state such as a high accuracy high base state or a low accuracy high base state, it is more advantageous to allow the game ball to enter the right game area 6R (see FIG. 4) by hitting right. This is because the electric support control makes it easier to open the electric chew 12D than in the low base state, and it is easier to win the second starting port 12 than to win the first starting port 11. .. Therefore, while passing the game ball through the gate 13, which is an opportunity for the normal symbol lottery, a right-handed hit is made so that the game ball can be won in the second starting port 12. As a result, it is possible to obtain a large number of starting prizes (winning to the starting port) rather than hitting left. In this pachinko gaming machine PY1, the game is played by right-handed even during the jackpot game.

On the other hand, in the low base state, it is more advantageous to allow the game ball to enter the left game area 6L (see FIG. 4) by hitting the left side. Since the electric support control is not executed, it is difficult to open the electric chew 12D compared to the high base state, and it is easier to win the first starting port 11 than to win the second starting port 12. Because it has become. Therefore, a left-handed hit is made to make the first starting port 11 win a game ball. This allows you to get more start-up prizes than right-handed.

5. Operation of the Game Control Microcomputer 101 [Main Control Main Process] Next, the operation of the game control microcomputer 101 will be described with reference to FIGS. 13 to 27. The counter, timer, flag, status, buffer, etc. that appear in the operation description of the game control microcomputer 101 are provided in the game RAM 104. When the power of the pachinko gaming machine PY1 is turned on, the gaming control microcomputer 101 provided on the gaming control board 100 reads out and executes the main control main processing program shown in FIG. 13 from the gaming ROM 103. As shown in the figure, in the main control main process, the initial setting is first performed (step S001). In the initial settings, for example, stack settings, constant settings, interrupt time settings, gaming CPU 102 settings, SIO, PIO, CTC (circuit for interrupt time management) settings, various flags, statuses, counters, etc. Reset etc. The initial value of the flag is "0", that is, "OFF", the initial value of the status is "1", and the initial value of the counter is "0". The initial setting (S001) is executed only once after the power is turned on, and is not executed after that.

Following the initial setting (S001), interrupts are disabled (S002), and normal symbol / special symbol main random number update processing (S003) is executed. In this normal symbol / special symbol main random number update process (S003), various random number counter values shown in FIG. 9 are added and updated by 1. When each random number counter value reaches the upper limit value, it returns to "0" and is added again. The initial value of each random number counter may be a value other than "0" or may be randomly changed. Further, each random number may be a so-called hardware random number generated by using a known random number generation circuit including a counter IC or the like.

When the normal symbol / special symbol main random number update process (S003) is completed, interrupts are enabled (S004). While the interrupt is enabled, the main timer interrupt process (S005) can be executed. The main timer interrupt process (S005) is executed based on an interrupt pulse repeatedly input to the gaming CPU 102, for example, at a cycle of 4 msec. That is, for example, it is executed in a cycle of 4 msec. Then, between the end of the main timer interrupt process (S005) and the start of the next main timer interrupt process (S005), various counters by the normal symbol / special symbol main random number update process (S003). The value update process is executed repeatedly. If an interrupt pulse is input to the gaming CPU 102 in the interrupt disabled state, the main timer interrupt process (S005) is not started immediately, but is started after the interrupt is enabled (S004).

[Main-side timer interrupt processing] Next, the main-side timer interrupt processing (S005) will be described. As shown in FIG. 14, in the main side timer interrupt processing (S005), the output processing (S101) is first executed. In the output process (S101), in each process described below, commands and the like set in the output buffer provided in the game RAM 104 of the game control board 100 are output to the effect control board 120, the payout control board 170, and the like.

In the input processing (S102) performed after the output processing (S101), various sensors (first starting port sensor 11a, second starting port sensor 12a, gate sensor 13a, large prize) mainly attached to the pachinko gaming machine PY1 are awarded. The detection signal detected by the mouth sensor 14a, the general winning mouth sensor 10a, etc. (see FIG. 6) is read and stored (set) in the output buffer of the gaming RAM 104 as prize ball information. Further, the detection signal from the lower plate full switch that detects the fullness of the lower plate 35 is also taken in and stored in the output buffer of the game RAM 104 as the lower plate full data.

The normal symbol / special symbol main random number update process (S103) performed next is the same as the normal symbol / special symbol main random number update process (S003) performed in the main control main process of FIG. That is, the update processing of the various random number counter values (including the normal symbol random number counter value) shown in FIG. 9 includes the execution period of the main side timer interrupt processing (S005) and the other period (main side timer interrupt processing (S005). After the end of), it is performed both in the period until the next main side timer interrupt process (S005) is started).

Following the normal symbol / special symbol main random number update process (S103), the sensor detection process (S104), the normal operation process (S105), and the special operation process (S106), which will be described later, are executed. After that, other processing (S107) is executed to end the main timer interrupt processing (S005). As another process (S107), the second special figure holding indicator 83b is controlled to a display mode indicating the number based on the number of reserved balls in the special figure 2 described later, or based on the number of reserved balls in the special figure 1 described later. The first special figure holding display 83a is controlled in a display mode indicating the number thereof. Then, until the next interrupt pulse is input to the gaming CPU 102, the processes of steps S002 to S004 of the main control main process are repeatedly executed (see FIG. 13), and when the interrupt pulse is input (after about 4 msec), The main timer interrupt process (S005) is executed again. In the output process (S101) of the main side timer interrupt process (S005) executed again, the command or the like set in the output buffer of the game RAM 104 in the previous main side timer interrupt process (S005) is output.

[Sensor detection process] As shown in FIG. 15, in the sensor detection process (S104), first, it is determined whether or not the game ball has passed through the gate 13, that is, whether or not the game ball has been detected by the gate sensor 13a ( S201). If the game ball has passed through the gate 13 (YES in S201), the gate passing process described later is performed (S202). On the other hand, if the game ball has not passed through the gate 13 (NO in S201), the game passes the gate passing process (S202) and proceeds to step S203.

In step S203, it is determined whether or not the game ball has won a prize in the second starting port 12, that is, whether or not the game ball has been detected by the second starting port sensor 12a (S203). If the game ball has not won in the second starting port 12 (NO in S203), the process proceeds to step S207, but if the game ball has won in the second starting port 12 (YES in S203), the special figure 2 Whether or not the number of reserved balls (the number of the second special figure hold, specifically, the numerical value of the counter for counting the number of the second special figure hold provided in the gaming RAM 104) has reached "4" (upper limit storage number). Is determined (S204). Then, when the number of reserved balls in Special Figure 2 has reached "4" (YES in S204), the process proceeds to step S207, but when the number of reserved balls in Special Figure 2 is less than "4" (in S204). NO), 1 is added to the number of reserved balls in Special Figure 2 (S205).

Subsequently, the special figure 2 related random number acquisition process is performed (S206). In the special figure 2 related random number acquisition process (S206), the jackpot random number counter value (label-TRND-A), the hit type random number counter value (label-TRND-AS), the reach random number counter value (label-TRND-RC), and the fluctuation. The pattern random number counter value (label-TRND-T1) is acquired (that is, the random number value group shown in FIG. 9A is acquired), and the acquired random number value is used as the current special figure in the second special figure reservation storage unit 105b. 2 Stored in the storage area of the second special figure reserved storage unit 105b according to the number of reserved balls.

Subsequently, in the sensor detection process (S104), it is determined whether or not the game ball has won a prize in the first starting port 11, that is, whether or not the game ball has been detected by the first starting port sensor 11a (S207). If the game ball has not won a prize in the first starting port 11 (NO in S207), the process is completed, but if the game ball has won a prize in the first starting port 11 (YES in S207), the special figure 1 is suspended. Whether or not the number of balls (the number of the first special figure hold, specifically, the numerical value of the counter for counting the number of the first special figure hold provided in the gaming RAM 104) has reached "4" (upper limit storage number). Judgment (S208). Then, when the number of reserved balls in Special Figure 1 reaches "4" (YES in S208), the process ends, but when the number of reserved balls in Special Figure 1 is less than "4" (NO in S208). ), Add "1" to the number of reserved balls in Special Figure 1 (S209).

Subsequently, the special figure 1 related random number acquisition process (S210) is performed to complete this process. In the special figure 1 related random number acquisition process (S210), the jackpot random number counter value (label-TRND-A) and the hit type random number counter value (label-TRND-AS) are the same as in the special figure 2 related random number acquisition process (S206). , Acquire the reach random number counter value (label-TRND-RC) and the fluctuation pattern random number counter value (label-TRND-T1) (that is, acquire the random number value group shown in FIG. 9A), and obtain the acquired random number values. It is stored in the storage area of the first special figure reservation storage unit 105a according to the current number of special figure 1 reservation balls in the first special figure reservation storage unit 105a.

[Gate Passing Process] As shown in FIG. 16, in the gate passing process (S202), a counter that counts the number of normal symbol holding balls (the number of normal symbol holdings, specifically, the number of normal drawing holdings provided in the gaming RAM 104). (Value of S301) is 4 or more (S301), and if the number of normal symbol reserved balls is 4 or more (YES in S301), the process is terminated. On the other hand, if the number of normal symbol reserved balls is not 4 or more (NO in S301), "1" is added to the number of normal symbol reserved balls (S302), and the normal symbol random number acquisition process is performed (S303). In the normal symbol random number acquisition process (S303), the normal symbol random number counter value (value of label-TRND-H, see FIG. 9B) is acquired, and the acquired random number value is stored in the normal symbol hold storage unit 106 of the gaming RAM 104. Of these, it is stored in the storage area according to the current number of reserved balls for ordinary symbols.

[Normal operation processing] The game control microcomputer 101 performs normal operation processing (S105) following sensor detection processing (S104) (see FIG. 14). As shown in FIG. 17, in the normal operation process (S105), first, it is determined whether or not the electric chew 12D is in operation (S401). If the electric chew 12D is not in operation (NO in S401), it is subsequently determined whether or not the stop display of the normal symbol is in progress (S402). If the normal symbol is not displayed as stopped (NO in S402), it is subsequently determined whether or not the normal symbol is being displayed in a variable manner (S403). Unless the fluctuation display of the normal symbol is being displayed (NO in S403), it is subsequently determined whether or not the number of reserved balls of the normal symbol is "0" (S404). If the number of reserved balls of the normal symbol is "0" (YES in S404), this process ends.

If the number of reserved balls of the normal symbol is not "0" in step S404 (NO in S404), the collision detection process is performed (S405). In the hit determination process (S405), the normal symbol random number counter value (value of label-TRND-H) stored in the normal symbol hold storage unit 106 is read out, and is based on the normal symbol hit determination table shown in FIG. 10 (C). Judge whether it is a hit or not. Then, a symbol determination process is performed in which the normal symbol stop symbol data according to the result of the hit determination is set in a predetermined storage area of the gaming RAM 104 (S406). That is, in the symbol determination process (S406), if it is "missing", the data corresponding to the "normal drawing losing symbol" is set, and if it is "hit", the data corresponding to the "normal winning symbol" is set.

Subsequently, the game control microcomputer 101 performs a normal symbol fluctuation time determination process (S407). In the normal symbol fluctuation time determination process (S407), referring to the normal symbol fluctuation pattern selection table shown in FIG. 10 (D), if the gaming state is in the reduced working hours state, the normal symbol fluctuation time is 1 second. Select a pattern. On the other hand, if the gaming state is a non-time saving state, a normal symbol variation pattern with a normal symbol variation time of 7 seconds is selected.

Next, the game control microcomputer 101 decrements the number of normally symbol reserved balls by 1 (S408). Then, the storage location (storage area) of each normal figure hold in the normal figure hold storage unit 106 is shifted by one to the side read from the current position, and the storage corresponding to the fourth hold in the normal figure hold storage unit 106 is performed. Clear the area (the storage area farthest from the read side) (S409). In this way, the general map hold is digested in the order in which it was held. After that, the game control microcomputer 101 starts the variation display of the normal symbol in the normal symbol variation pattern selected in step S407 (S410). Along with this, a command to start the fluctuation of the normal symbol is set in order to notify the effect control board 120 of the start of the fluctuation of the normal symbol.

If the fluctuation display of the normal symbol is being displayed in step S403 described above (YES in S403), it is subsequently determined whether or not the fluctuation time of the normal symbol has elapsed (S411), and if not, the process ends. On the other hand, if it has passed (YES in S411), the variable display of the normal symbol is stopped at the display result (normal hit symbol or normal lost symbol) according to the judgment result of the normal symbol random number (S412). Then, the normal symbol fluctuation stop command for notifying the normal symbol fluctuation stop is set on the effect control board 120 (S413), and the normal symbol stop time is set (S414), and this process is completed.

If the stop display of the normal symbol is being displayed in step S402 described above (YES in S402), then it is determined whether or not the stop time of the normal symbol set in step S414 has elapsed (S415), and the process has elapsed. If not, the process ends. On the other hand, if it has passed (YES in S415), it is determined whether or not the normal symbol stop symbol data of the normal hit symbol is set (S416), and if it is not the normal hit symbol data (that is, if it is not a hit). (NO in S416)), this process is completed. On the other hand, if it is the data of the normal hit symbol (that is, if it is a hit (YES in S416)), the open pattern of the electric chew 12D is set (S417). Specifically, if it is in the time saving state, the opening pattern in the time saving state (see the electric chew opening TBL2 in FIG. 12) is set as the opening pattern of the electric chew 12D. On the other hand, if it is in the non-time saving state, the opening pattern in the non-time saving state (see the electric chew opening TBL1 in FIG. 12) is set as the opening pattern of the electric chew 12D. Then, the electric chew 12D is operated according to the opening pattern set in step S417 (S418).

Further, if the electric chew 12D is operating in step S401 described above (YES in S401), it is subsequently determined whether or not the operating time of the electric chew 12D has elapsed (S419), and if not. Finish the process. On the other hand, if it has passed (YES in S419), the operation of the electric chew 12D is terminated (S420).

[Special operation processing] The game control microcomputer 101 performs special operation processing (S106) following normal operation processing (S105) (see FIG. 14). As shown in FIG. 18, in the special operation process (S106), the process related to the special figure display 81 and the grand prize device 14D is divided into four stages, and "special operation status 1, 2, 3, 4" is set in each stage. Is assigned. Then, when the "special operation status" is "1" (YES in S1301), the game control microcomputer 101 performs the special symbol standby process (S1302), and the "special operation status" is "2". If (NO for S1301, YES for S1303), special symbol change processing (S1304) is performed, and if the "special operation status" is "3" (NO for both S1301 and S1303, YES for S1305). , The special symbol determination process (S1306) is performed, and when the "special operation status" is "4" (all of S1301, S1303, S1305 are NO), the special electric accessory process (S1307) is performed. The special operation status is "1" by default.

[Special symbol standby process] As shown in FIG. 19, in the special symbol standby process (S1302), first, whether or not the number of reserved balls in the second starting port 12 (that is, the number of reserved balls in special figure 2) is "0". Is determined (S1401). Special figure 2 When the number of reserved balls is "0" (YES in S1401), that is, when there is no memory of the random number counter value group acquired due to the winning of the second starting port 12, the first starting It is determined whether or not the number of reserved balls in the mouth 11 (that is, the number of reserved balls in Special Figure 1) is "0" (S1407). Then, when the number of reserved balls in Special Figure 1 is also "0" (YES in S1407), that is, when there is no memory of the random number counter value group acquired due to the winning of the first starting port 11, the customer Determines whether the wait flag is ON (S1415). If it is ON (YES in S1415), this process is completed, and if it is not ON (NO in S1415), the customer wait command is set in the output buffer of the game RAM 104 (S1416), and the customer wait flag is turned ON (S1416). S1417), this process is completed.

When the number of reserved balls in special figure 2 is not "0" in step S1401 (NO in S1401), that is, the memory of the random number counter value group acquired due to the winning of the second starting port 12 (holding information in special figure 2). ) Is one or more, the special figure 2 jackpot determination process (S1402) and the special figure 2 fluctuation pattern selection process (S1403), which will be described later, are performed. After that, the game control microcomputer 101 decrements the number of reserved balls in FIG. 2 by 1 (S1404). Then, the storage location (storage area) of various counter values in the second special figure reservation storage unit 105b is shifted by one to the side read from the current position, and the first reservation in the second special figure reservation storage unit 105b is performed. Clear the storage area corresponding to (S1405). Subsequently, the game control microcomputer 101 executes the special figure 2 fluctuation start process (S1406), and proceeds to step S1413. In the special figure 2 variation start process (S1406), the special operation status is set to "2" and the variation start command is set in the output buffer of the game RAM 104 to start the variation display of the second special symbol. The fluctuation start command (also referred to as the special figure 2 fluctuation start command) set in the special figure 2 fluctuation start process (S1406) is the special figure stop symbol data set in the special figure 2 jackpot determination process (S1402). Information and information on the fluctuation pattern set in the special figure 2 fluctuation pattern selection process (S1403) (information including information on the fluctuation time) are included.

Further, when the number of reserved balls in Special Figure 2 is "0" but the number of reserved balls in Special Figure 1 is not "0" (YES in S1401 and NO in S1407), that is, there is no hold information in Special Figure 2, but the number is higher. When there is one or more storages (holding information of special figure 1) of the random number counter value group acquired due to the winning of the 1 starting port 11, the special figure 1 jackpot determination process (S1408) and the special figure described later are performed. 1 Perform the variation pattern selection process (S1409). After that, the game control microcomputer 101 decrements the number of reserved balls in FIG. 1 by 1 (S1410). Then, the storage location (storage area) of various counter values in the first special figure reservation storage unit 105a is shifted by one to the side read from the current position, and the fourth reservation in the first special figure reservation storage unit 105a is performed. Clears the storage area corresponding to (S1411). In this way, the first special figure hold is digested in the order in which it was held. Subsequently, the game control microcomputer 101 executes the special figure 1 fluctuation start process (S1412), and proceeds to step S1413. In the special figure 1 fluctuation start processing (S1412), the special operation status is set to "2" and the fluctuation start command is set in the output buffer of the game RAM 104 to start the fluctuation display of the first special symbol. The fluctuation start command (also referred to as the special figure 1 fluctuation start command) set in the special figure 1 fluctuation start process (S1412) is the special figure stop symbol data set in the special figure 1 jackpot determination process (S1408). Information and information on the fluctuation pattern set in the special figure 1 fluctuation pattern selection process (S1409) (information including information on the fluctuation time) are included.

When the process proceeds to step S1413, it is determined whether or not the customer waiting flag is ON, and if it is ON, the customer waiting flag is turned OFF (S1414), and the process is completed. As described above, in the present embodiment, the variable display of the special symbol based on the first special figure hold is performed only when the second special figure hold is "0" (when YES in S1401). That is, the digestion of the second special figure hold is executed in preference to the digestion of the first special figure hold.

[Special Figure 2 Big Hit Judgment Process (Special Figure 1 Big Hit Judgment Process)] Special Figure 2 Big Hit Judgment Process (S1402) and Special Figure 1 Big Hit Judgment Process (S1408) are based on FIG. 20 because the processing flow is the same. I will explain them all together. As shown in FIG. 20, in the special figure 2 jackpot determination process (S1402) or the special figure 1 jackpot determination process (S1408), first, the jackpot random number counter value (label-TRND-A value) is read out as the determination value (S1501). ). Specifically, in the special figure 2 jackpot determination process (S1402), in the first storage area of the second special figure reservation storage unit 105b of the gaming RAM 104 (that is, the storage area corresponding to the first storage area of the second special figure reservation). Read the stored jackpot random number counter value. Further, in the special figure 1 jackpot determination process (S1408), it is stored in the first storage area (that is, the storage area corresponding to the first storage area of the first special figure hold) of the first special figure hold storage unit 105a of the gaming RAM 104. Read the jackpot random number counter value.

Next, the jackpot determination table (FIG. 10 (A)) is set (S1502). Next, it is determined whether or not the probability variation flag is ON, that is, whether or not it is in a high probability state (S1503). Then, if it is not a high probability state (NO in S1503), that is, if it is a normal probability state (non-high probability state), the table for the non-high probability state (big hit judgment) in the jackpot determination table (FIG. 10A). It is determined whether or not the value is a big hit based on "1" to "210") (S1504). On the other hand, if it is a high probability state (YES in S1503), is it a big hit based on the table for the high probability state (big hit judgment value is "1" to "1660") in the big hit judgment table (FIG. 10 (A))? Determine if not (S1505).

If the result of the jackpot determination (S1504, S1505) is "big hit", the hit type random number counter value (label-TRND-AS value) is read out, and the hit type is determined based on the hit type determination table shown in FIG. (S1506). After determining the hit type (S1506), the jackpot flag is turned ON (S1507), and the special figure stop symbol data (see FIG. 8) according to the hit type is set in the hit type buffer provided in the game RAM 104. (S1508) Finish the process. On the other hand, if the result of the jackpot determination (S1504, S1505) is "missing", the special symbol stop symbol data (01H) corresponding to the losing symbol is set and the process (S1508) is completed.

[Special Figure 2 Fluctuation Pattern Selection Process (Special Figure 1 Fluctuation Pattern Selection Process)] Special Figure 2 Fluctuation Pattern Selection Process (S1403) and Special Figure 1 Fluctuation Pattern Selection Process (S1409) have the same processing flow. A description will be given collectively with reference to FIGS. 21 and 22. As shown in FIG. 21, in the special figure 2 variation pattern selection process (S1403) or the special figure 1 variation pattern selection process (S1409), first, it is determined whether or not the game state is the time reduction state (whether or not the time reduction flag is ON). (S1601).

If it is not in the time saving state (NO in S1601), that is, if it is in the non-time saving state, it is subsequently determined whether or not the jackpot flag is ON (S1602). If it is ON (YES in S1602), refer to the non-time saving state medium jackpot normal table (the part corresponding to the non-time saving state and jackpot in the special figure fluctuation pattern determination table shown in FIG. 11), and the fluctuation pattern random number counter value. The variation pattern is selected based on (value of label-TRND-T1) (S1603). As shown in FIG. 11, once the fluctuation pattern is determined, the fluctuation time is also determined.

In the variable effect of the pachinko gaming machine PY1, as described above, SP (super reach) can be executed in addition to the do-miss and normal reach. Therefore, as shown in FIG. 11, the fluctuation pattern is selected so that the loss, the normal reach, and the SP reach can be executed. The SP reach (super reach) shown in the remarks column of FIG. 11 is a reach in which the fluctuation time after the reach is longer than that of the normal reach. The distribution rate of the table is set so that the SP reach has a higher expectation of winning (expectation for big hit winning) than the normal reach. Here, the types of SP reach include weak SP reach A, weak SP reach B, and strong SP reach. In the order of weak SP reach A ⇒ weak SP reach B ⇒ strong SP reach, the distribution rate of various fluctuation patterns is set so that the degree of expectation of winning the jackpot is high.

In step S1602 shown in FIG. 21, if the jackpot flag is not ON, it is determined whether or not the reach random number counter value (value of label-TRND-RC) is the reach establishment random number value (S1604). As shown in FIG. 10B, the reach establishment random number values are "1" to "30" in the non-time saving state, and "1" to "10" in the time saving state. That is, the time-saving state is less likely to reach the loss time than the non-time-saving state. This is to accelerate the digestion speed of the special figure hold by allowing more non-reach loss with a short fluctuation time to be selected in the time saving state.

When the reach random number counter value is the reach establishment random number value (YES in S1604), that is, in the case of the loss with reach, the loss table with reach during the non-time saving state (not among the special figure fluctuation pattern determination tables shown in FIG. 11). The fluctuation pattern is selected based on the fluctuation pattern random number counter value with reference to the time-saving state and the part corresponding to the loss with reach (S1605).

On the other hand, when the reach random number counter value is not the reach establishment random number value (NO in S1604), that is, in the case of loss without reach, the loss table without reach during the non-time saving state (of the special figure fluctuation pattern determination table shown in FIG. 11). The fluctuation pattern is selected based on the fluctuation pattern random number counter value with reference to the non-time saving state and the part corresponding to the loss without reach (S1606). At the time of this loss without reach, the function of shortening fluctuation according to the number of reserved balls works. That is, when the number of reserved balls of the special symbol is "3" or "4", a fluctuation pattern having a shorter fluctuation time than when the number of reserved balls of the special symbol is "0" to "2" is selected. (See FIG. 11).

Further, in step S1601, when it is determined that the gaming state is in the time saving state (YES in S1601), as shown in FIG. 22, the special figure variation pattern determination table to be referred to is set to the table in the time saving state (shown in FIG. 11). Processing (S1607 to S1611) is performed in the same flow as in steps S1602 to S1606 above, except that the part corresponding to the time saving state in the special figure fluctuation pattern determination table) is set.

That is, if it is a big hit, the fluctuation pattern is selected based on the fluctuation pattern random number counter value with reference to the portion corresponding to the jackpot in the time saving state of FIG. 11 (S1608). Further, in the case of a loss with reach, the variation pattern is selected based on the variation pattern random number counter value with reference to the portion corresponding to the loss with reach during the time saving state in FIG. 11 (S1610). Further, in the case of loss without reach, the variation pattern is selected based on the variation pattern random number counter value with reference to the portion corresponding to the loss without reach during the time saving state in FIG. 11 (S1611).

In the special figure fluctuation pattern determination table during the time reduction state (the part corresponding to the time reduction state in the special figure fluctuation pattern determination table shown in FIG. 11), the function of shortening fluctuation according to the number of reserved balls at the time of loss without reach is provided. It works when the number of reserved balls is "2" to "4". That is, the shortened variation is more likely to be selected than in the non-time saving state. Further, the fluctuation time as the shortened fluctuation is shorter in the time-reduced state than in the non-time-reduced state. That is, the special figure fluctuation pattern determination table in the time saving state is a table in which the fluctuation time is shorter than the special figure fluctuation pattern determination table in the non-time saving state.

After selecting the variation pattern as described above, as shown in FIG. 21, the selected variation pattern is set (S1612), and the present process is completed. The fluctuation pattern information set in step S1612 is included in the fluctuation start command set in step S1406 or S1412 in the special symbol standby process (S1302), and is sent to the effect control board 120 by the output process (S101).

[Process during special symbol change] As shown in FIG. 23, in the special symbol change process (S1304), first, the change time of the special symbol (the change time determined according to the change pattern selected in step S1403 or S1409, FIG. 11). (See) is determined whether or not it has passed (S1801). If it has not passed (NO in S1801), this process is finished immediately. As a result, the variable display of the special symbol is continued.

On the other hand, if the fluctuation time has elapsed (YES in S1801), the fluctuation stop command is set (S1802) and the special operation status is set to "3" (S1803). Then, after performing other processing such as stopping the variable display of the special symbol at the symbol (big hit symbol or lost symbol) corresponding to the set special symbol stop symbol data (S1804), this process is terminated.

[Special symbol confirmation process] As shown in FIG. 24, in the special symbol determination process (S1306), first, the stop time of the special symbol (stop time determined according to the fluctuation pattern selected in step S1403 or S1409, see FIG. 11). Determines whether or not has passed (S1901). If it has not passed (NO in S1901), this process is finished immediately. As a result, the stop display of the special symbol is continued. On the other hand, if the stop time has elapsed (YES in S1901), the game state management process described later is performed (S1902).

Next, it is determined whether or not the jackpot flag is ON (S1903). If the jackpot flag is ON (YES in S1903), an opening pattern (see FIG. 8 for details) according to the type of winning jackpot is set (S1904). At this time, the value of the round counter that counts the number of unit opening games (round games) executed during the jackpot game is set to the number of rounds according to the type of winning jackpot. The open pattern set (data set according to the open pattern) may be performed for each round.

The game control microcomputer 101 performs a game state reset process following step S1904 (S1905). In the game state reset process (S1905), first, if the probability change flag is ON, the probability change flag is turned off, and if the time reduction flag is ON, the probability change flag is turned off. That is, during the execution of the jackpot game, it is controlled to a non-high probability state and a non-time saving state. After that, in order to start the big hit game, the opening command of the big hit is set (S1906), and the opening of the big hit game is started (S1907). Then, the special operation status is set to "4" (S1908), and this process is completed.

If the jackpot flag is not ON in step S1903 (NO in S1903), the jackpot game will not start, so the special operation status is set to "1" (S1909), and this process ends.

[Game state management process] As shown in FIG. 25, in the game state management process (S1902), first, it is determined whether or not the probability change flag is ON (S2001). If it is ON (YES in S2001), the value of the probability variation counter that counts the number of fluctuations of the special symbol executed during the high probability state is decremented by 1 (S2002), and whether the value of the probability variation counter is "0" or not. Judgment (S2003). If it is "0" (YES in S2003), the probability change flag is turned off (S2004), and the process proceeds to step S2005. If the determination result of step S2001 or S2003 is NO, the process immediately proceeds to step S2005.

In step S2005, it is determined whether or not the time saving flag is ON. If it is ON (YES in S2005), the value of the time reduction counter that counts the number of fluctuations of the special symbol executed during the time reduction state is decremented by 1 (S2006), and it is determined whether the value of the time reduction counter is "0". (S2007). If it is "0" (YES in S2007), the time saving flag is turned off (S2008), and the process proceeds to step S2009. If the determination result in step S2005 or S2007 is NO, the process immediately proceeds to step S2009. In step S2009, a game state specification command including information on the current game state (information on whether the probability change flag and the time reduction flag are ON or OFF), information on the value of the probability change counter and the value of the time reduction counter, etc. is used for the game. It is set in the output buffer of the RAM 104, and this processing is completed.

[Special electric bonus processing (big hit game)] As shown in FIG. 26, in the special electric bonus processing (S1307), first, it is determined whether or not the jackpot end flag is ON (S2201). The jackpot end flag is a flag indicating that all the jackpots 14 have been opened in the jackpot game being executed.

If the jackpot end flag is not ON (NO in S2201), it is determined whether or not the jackpot 14 is open (S2202). If it is not open (NO in S2202), it is time to open the big prize opening 14, that is, whether the opening time of the jackpot game has passed and the opening start time in the first round game has been reached, or , It is determined whether or not the interval time (closing time) until the once closed large winning opening 14 is opened again has elapsed and the opening start time has been reached (S2203).

If the determination result in step S2203 is NO, the process ends as it is. On the other hand, if the determination result in step S2203 is YES, the big winning opening 14 is opened according to the opening pattern (see FIG. 8) according to the type of big hit (S2204).

In the following step S2205, the round designation command transmission determination process is performed. In the round designation command transmission determination process (S2205), it is determined whether or not the opening of the big winning opening 14 in step S2204 is the first opening in one round game, and if so, the running big hit game. A round specification command containing information on the number of rounds is set in the output buffer of the gaming RAM 104. In this embodiment, the large winning opening 14 is not opened a plurality of times during one round game. Therefore, in this step S2205, the round specification command is always set.

In step S2202 of the special electric accessory processing (S1307), if the large winning opening 14 is being opened (YES in S2202), it is determined whether or not the closing condition of the large winning opening 14 is satisfied (S2206). In this embodiment, the closing condition is that the number of winnings to the large winning opening 14 in the round game reaches the specified maximum winning number (8 per 1R in this embodiment), or the time to close the large winning opening 14. (That is, a predetermined opening time (see FIG. 8) has elapsed since the opening of the large winning opening 14) is satisfied. Then, if the closing condition of the large winning opening 14 is not satisfied (NO in S2206), the process is completed.

On the other hand, if the closing condition of the big winning opening 14 is satisfied (YES in S2206), the big winning opening 14 is closed (closed) (S2207). Then, it is determined whether or not one round game is completed by closing step S2207 (S2208). If one round game is not completed (NO in S2208), this process is completed. On the other hand, when one round game is completed (YES in S2208), the value of the round counter is decremented by 1 (S2209), and it is determined whether or not the value of the round counter is "0" (S2210). .. If it is not "0" (NO in S2210), the process is finished as it is in order to start the next round game.

On the other hand, if it is "0" (YES in S2210), the jackpot ending command is set (S2211) and the jackpot ending is started (S2212) as the jackpot ending process for ending the jackpot game. Then, the jackpot end flag is set (S2213), and the process is completed.

If the jackpot end flag is ON in step S2201 (YES in S2201), the final round has ended, so it is determined whether or not the jackpot ending time has elapsed (S2214). If the ending time has not elapsed (NO in S2214), the process ends. On the other hand, if the ending time has elapsed (YES in S2214), the jackpot end flag is turned off (S2215), the jackpot flag is turned off (S2216), and the special operation status is set to "1" (S2217). As a result, in the next main side timer interrupt process (S005), the special symbol standby process (S1302) is executed again as the special operation process (see FIG. 18). After that, the game state setting process (S2218) described later is performed to complete this process.

[Game state setting process] As shown in FIG. 27, in the game state setting process (S2218), first, the type of jackpot is a probability variation jackpot (the stop symbol is special figure 1_big hit symbol 1 or special figure 2_big hit symbol 1, see FIG. ) (S2301). If it is not a probable change jackpot (NO in S2301), turn on the time saving flag (S2306), set "100" in the time saving counter (S2307), and proceed to step S2308. As a result, the gaming state after the big hit game this time becomes a normal probability state, a time saving state, and a high base state (that is, a low probability high base state). This low-accuracy high-based state ends when either the condition that the variable display of the special symbol is performed 100 times or that the next big hit is won is satisfied.

On the other hand, if it is a probability change jackpot in step S2301, the probability change flag is turned ON (S2302) and the time saving flag is turned ON (S2303). Then, "10000" is set in the probability variation counter (S2304), "10000" is set in the time reduction counter (S2305), and the process proceeds to step S2308. As a result, the gaming state after the big hit game this time becomes a high probability state, a time saving state, and a high base state (that is, a high probability high base state). This high accuracy and high base state will continue until the next big hit is won. Since it is almost impossible that the fluctuation display of the special symbol is executed until the value of the probability variation counter and the value of the time reduction counter change from "10000" to "0", the probability variation flag and the time reduction flag are set to the next jackpot game. This is because it will not be turned off until it is turned off. It should be noted that the probability variation counter may not be provided and only the probability variation flag may be used so that the high probability state continues until the next big hit is won.

In step S2308, a game state specification command including information on the current game state (information on whether the probability change flag and the time reduction flag are ON or OFF), information on the value of the probability change counter, information on the value of the time reduction counter, etc. is used for the game. It is set in the output buffer of the RAM 104, and this processing is completed.

6. Change of background image Next, before explaining the operation of the effect control microcomputer 121, the change of the background image, which is a feature of this embodiment, will be described. The background image is an image displayed as a background on the display screen 50a of the image display device 50 behind the effect symbol EZ, the hold icon HA, each image related to the advance notice effect, and the like. In the present embodiment, as the background image displayed in the normal gaming state, as shown in FIG. 28, there are six types of background images having different background modes.

As shown in FIG. 28 (A), the background image which is the background aspect (first background aspect) showing the scenery of the mountain in the daytime is referred to as "first background image HK1". Further, as shown in FIG. 28B, the background image which is the background aspect (second background aspect) showing the scenery of the mountain at night is referred to as "second background image HK2". Further, as shown in FIG. 28C, the background image which is the background aspect (third background aspect) showing the scenery of the city in the daytime is referred to as "third background image HK3". Further, as shown in FIG. 28 (D), the background image which is the background aspect (fourth background aspect) showing the scenery of the city at night is referred to as "fourth background image HK4". Further, as shown in FIG. 28 (E), the background image which is the background aspect (fifth background aspect) showing the earth in space is referred to as "fifth background image HK5". Further, as shown in FIG. 28 (F), the background image which is the background aspect (sixth background aspect) showing Saturn in space is referred to as "sixth background image HK6". The description of the background image displayed in the high accuracy high base state and the background image displayed in the low accuracy high base state will be omitted.

Further, in the present embodiment, as shown in FIG. 28, the effect symbols EZ displayed in the normal gaming state include three types of effect symbols having different display modes. Specifically, "1st production design EZa" reminiscent of the hero's childhood, "2nd production design EZb" reminiscent of the hero's high school days, and "3rd production design" reminiscent of the hero's professional era. There are three types of "directed design EZc".

As shown in FIGS. 28 (A) and 28 (B), as the first production symbol EZa, the first production symbol EZa showing the childhood of the main character and the number "7", the childhood of the rival character which is a rival of the main character. There is a first production design EZa that shows the era and the number "9", and a first production design EZa that shows the childhood of the older sister character who is the sister of the main character and the number "1". Here, as the first production symbol EZa, the first production symbol EZa showing the numbers from "1" to "9" is prepared, and each has a character reminiscent of the childhood of the main character. 1 It is a production pattern EZa. That is, in the display mode (first display mode) of the first effect symbol EZa, a character reminiscent of the childhood of the main character is shown.

As shown in FIGS. 28 (C) and 28 (D), as the second production symbol EZb, the second production symbol EZb showing the high school days of the main character and the number "7", the high school of the rival character which is a rival of the main character. There is a second production design EZb that shows the era and the number "9", a second production design EZb that shows the high school age of the older sister character who is the sister of the main character, and the number "1". Here, as the second production symbol EZb, the second production symbol EZb showing the numbers from "1" to "9" is prepared, and each of them has a character reminiscent of the high school days of the main character. 2 It is a production pattern EZb. That is, in the display mode (second display mode) of the second production symbol EZb, a character reminiscent of the high school days of the main character is shown.

As shown in FIGS. 28 (E) and 28 (F), as the third production symbol EZc, the third production symbol EZc showing the pro era of the main character and the number "7", the pro of the rival character which is a rival of the main character. There is a third production pattern EZc that shows the era and the number "9", and a third production design EZc that shows the adult era of the older sister character who is the sister of the main character and the number "1". Here, as the third production symbol EZc, the third production symbol EZc showing the numbers from "1" to "9" is prepared, and each has a character reminiscent of the professional era of the main character. 3 The production pattern is EZc. That is, in the display mode (third display mode) of the third effect symbol EZc, the character is reminiscent of the professional era of the main character. The description of the effect symbol displayed in the high accuracy and high base state and the effect symbol displayed in the low accuracy and high base state will be omitted.

Here, in the present embodiment, as shown in FIG. 28, the type of the effect symbol EZ (specific image) is determined according to the type of the background image. That is, the first effect symbol EZa is displayed only when it is the first background image HK1 or the second background image HK2, and the third background image HK3, the fourth background image HK4, the fifth background image HK5, and the sixth background image. If it is HK6, it will not be displayed. In this way, it can be said that the first background image HK1 and the second background image HK2 are the display conditions of the first production symbol EZa, and are in the "first production symbol group" reminiscent of the childhood of the main character. .. Further, the second effect symbol EZb is displayed only when it is the third background image HK3 or the fourth background image HK4, and the first background image HK1, the second background image HK2, the fifth background image HK5, and the sixth background image HK6. If is, it will not be displayed. In this way, the third background image HK3 and the fourth background image HK4 are the display conditions for the second production symbol EZb, and can be said to be in the "second production symbol group" reminiscent of the high school days of the main character. .. Further, the third effect symbol EZc is displayed only when it is the fifth background image HK5 or the sixth background image HK6, and the first background image HK1, the second background image HK2, the third background image HK3, and the fourth background image HK4. If is, it will not be displayed. In this way, the fifth background image HK5 and the sixth background image HK6 are the display conditions for the third production symbol EZc, and can be said to be in the "third production symbol group" reminiscent of the professional era of the main character. ..

Here, in the present embodiment, six types of background images (first background image HK1, second background image HK2, third background image HK3, fourth background image HK4, and fifth background) are established based on the establishment of a predetermined background change condition. The current background image can be changed to another background image by lottery from the image HK5 and the sixth background image HK6). This makes it possible for the player to make the background image less likely to get bored. However, changing the background image (changing the background aspect) has the following problems.

For example, when the first background image HK1 (see FIG. 28 (A)) is displayed, it is assumed that the background change condition is satisfied and the first background image HK1 is changed to the second background image HK2. In this case, in this embodiment, the first effect symbol EZa is displayed (variable display and stop display) regardless of whether the first background image HK1 is being displayed or the second background image HK2 is being displayed. , The production design will not be changed. After that, it is assumed that the background change condition is satisfied when the background image at the present time is the second background image HK2, and the change to the first background image HK1 is decided by lottery. In that case, by changing from the second background image HK2 to the first background image HK1, it means that the player immediately returns to the first background image HK1 from the viewpoint of the player. As a result, the player may have the impression that the same background image appears frequently, which may lead to a decrease in the interest of the production.

Further, when the first background image HK1 is changed to the first background image HK1 via the second background image HK2, the effect symbol EZ remains the first effect symbol EZa, and the effect symbol EZ is not changed during that time. It will be different. On the other hand, it is conceivable to provide 6 types of effect symbols EZ corresponding to each of the 6 types of background images. However, in this case, every time the background image is changed, the effect symbol EZ is always changed. As a result, there is a possibility that the player may have the impression that the effect pattern EZ has been changed excessively. As described above, it is possible to prevent the effect symbol EZ from being changed by changing the background image, and to prevent the effect symbol EZ from being excessively changed, so that the effect symbol EZ is appropriately changed. Needed to be improved.

Therefore, in this embodiment, as shown in FIG. 28, in order to deal with the above-mentioned problems, the types of the effect symbols EZ are set to three types, which are less than the types of the background image (first effect symbol group and second effect symbol). (Divided into a group and a third effect symbol group), the change of the background image is adjusted as follows. First, when the background image at the present time is in a certain effect symbol group, basically, the probability of being changed to another background image in the effect symbol group (transition rate) is increased, and another effect symbol is used. Reduce the probability of being changed to another background image in the group.

For example, it is assumed that the background image at the present time is the first background image HK1. In this case, basically, the probability of being changed to the second background image HK2 (another background image) in the same first effect symbol group is high (60% in this embodiment), and it is different. The probability of being changed to the third background image HK3 or the fourth background image HK4 in the second effect symbol group of No. 5 and the fifth background image HK5 or the sixth background image HK6 in another third effect symbol group is low (this embodiment). Then, each is 10%). As a result, it is basically easy to change from the first background image HK1 to the second background image HK2, so that it is difficult to change the effect symbol EZ as the first effect symbol EZa. As a result, even if the first background image HK1 is changed to the second background image HK2, it is possible to show the player a variable display of the same first effect symbol EZa, and it is possible to prevent an excessive change of the effect symbol EZ. It is possible to do.

On top of that, in this embodiment, exceptionally, when the background image immediately before being changed to the background image at the present time is another background image in the same effect symbol group, the background image at the present time is changed to another background. I try not to change it to an image. For example, as described above, it is assumed that the first background image HK1 has been changed to the second background image HK2. In this case, the background image at the present time is the second background image HK2, and the background image immediately before being changed to the second background image HK2 is the first background image HK1 (other background) in the same first effect symbol group. Image). Then, when changing from the second background image HK2, the third background image HK3 or the fourth background image HK4 in another second effect symbol group, or another third effect symbol is not changed to the first background image HK1. We will change to either the 5th background image HK5 or the 6th background image HK6 in the group.

In this way, it is possible to prevent the background image from being continuously changed twice in the same effect symbol group. That is, in the above example, in the first effect symbol group, it is possible to prevent the first background image HK1 from returning to the first background image HK1 via the second background image HK2. As a result, it is possible to prevent the player from giving the impression of returning to the same background image immediately. That is, it is possible not to give the impression that the same background image appears frequently, and it is possible to enhance the interest of the production.

And in this embodiment, exceptionally, when the background image immediately before being changed to the background image at the present time is another background image in the same effect symbol group, the change of the background image always causes another effect symbol. It is changed to the background image of the group. Therefore, in this case, the display mode of the effect symbol EZ is always changed by changing the background image. That is, in the above example, when the first background image HK1 is changed to the second background image HK2, then any of the third background image HK3, the fourth background image HK4, the fifth background image HK5, and the sixth background image HK6. Therefore, the effect symbol EZ is always changed from the first effect symbol EZa to the second effect symbol EZb or the third effect symbol EZc. As a result, it is possible to prevent a situation in which the background image is changed many times in the same effect symbol group and the effect symbol EZ is not changed for a while.

In short, basically, by increasing the probability (transition rate) of being changed to another background image in the same effect symbol group, it is possible to prevent an excessive change of the effect symbol EZ. In addition, as an exception, if the background image immediately before being changed to the current background image is another background image in the same effect symbol group, be sure to change to the background image of another effect symbol group. .. This makes it possible to prevent a situation in which the display mode of the effect symbol EZ does not change for a while. In this way, it is possible to achieve both an appropriate change in the display mode of the effect symbol EZ and prevention of frequent appearance of the background image of the same background mode.

Here, in the present embodiment, the background change condition for changing the background image in the normal gaming state will be described. The background change condition is that the number of times of variation display of the effect symbol EZ in the normal gaming state (number of variation effects) is 20 times or more, and the background image is changed using the background change execution lottery table shown in FIG. 44. It holds only when it is decided. That is, when the number of fluctuation effects in the normal gaming state is less than 20, the background image is not changed. Further, even if the number of fluctuation effects in the normal game state is 20 or more, if it is not determined to execute the change of the background image using the background change execution lottery table shown in FIG. 44, the background image is changed. There is no. The number of variable effects is reset to "0" when the big hit game (big hit effect) is started.

In this embodiment, as shown in FIG. 28, the first background image HK1 and the second background image HK2 can both be said to be the same type of background image in the sense that they both show a mountain landscape, and other backgrounds. The image can be called a different kind of background image. Further, the third background image HK3 and the fourth background image HK4 can both be said to be the same type of background image in the sense that they both show the scenery of the city, and the other background images can be said to be different types of background images. .. Further, the fifth background image HK5 and the sixth background image HK6 can both be said to be the same type of background image in the sense that they both show the scenery of the universe, and the other background images can be said to be different types of background images. .. Therefore, in this embodiment, basically, the probability (transition rate) of changing from the current background image to the same type of background image is increased. On top of that, when the background image before the background image at the present time is the same type of background image, there is an exception that the background image is always changed to a different type of background image. In this way, it is possible to show the background change in a well-balanced manner by appropriately showing the player the same type of background image and not showing the same type of background image three times in a row.

Next, an example of effect when the background image is changed will be described with reference to FIG. 29. First, as shown in FIG. 29 (A), it is assumed that the first background image HK1 is displayed on the display screen 50a, and the first effect symbol EZa is variablely displayed. As a precondition, it is assumed that the second background image HK2, which is the same first effect symbol group, is not displayed as the background image before the first background image HK1 shown in FIG. 29 (A) is displayed. Then, as shown in FIG. 29B, the first effect symbol EZa is stopped and displayed in, for example, the loss mode "179" while the first background image HK1 is displayed.

After that, it is assumed that the background change condition is satisfied when the variation effect is newly started. In this case, the change of the background image is determined by lottery so that the probability (transition rate) of being changed to the second background image HK2, which is the same first effect symbol group, is high (FIG. 45 (B). )reference). Therefore, it is decided to change to the second background image HK2. Further, in this case, since the first effect symbol EZa is to be displayed while the second background image HK2 is being displayed (see FIG. 45B), the display mode of the effect symbol EZ should not be changed. become.

As a result, as shown in FIG. 29 (C), the display screen 50a is switched to the display of the second background image HK2, and the variable display of the first effect symbol EZa is started. In this way, although the background aspect of the background image is changed, the display aspect of the effect symbol EZ is not changed, so that it is possible to prevent the effect symbol EZ from being excessively changed. Then, as shown in FIG. 29 (D), the first effect symbol EZa is stopped and displayed in, for example, the loss mode "199" while the second background image HK2 is displayed.

After that, it is assumed that the background change condition is satisfied when the variation effect is newly started. However, in this case, the background image immediately before being changed to the current background image (second background image HK2) is another background image (first background) in the same effect symbol group (first effect symbol group). Image HK1). Therefore, from the background images other than the current second background image HK2 and the immediately preceding first background image HK1 (third background image HK3, fourth background image HK4, fifth background image HK5, sixth background image HK6). , The background image to be changed will be determined by lottery (see FIG. 46 (A)). Therefore, at this time, it is determined that the background image is changed to the fourth background image HK4. In this case, since the second effect symbol EZb is to be displayed while the fourth background image HK4 is displayed (see FIG. 46 (A)), the first effect symbol EZa is changed to the second effect symbol EZb. It will be changed.

As a result, as shown in FIG. 29 (E), the display screen 50a is switched to the display of the fourth background image HK4, and the variable display of the second effect symbol EZb is started. In this way, if the display mode of the effect symbol EZ is not changed by the previous background change (change of the background image), the display mode of the effect symbol EZ will always be changed in this background change, and the effect symbol EZ will be changed. It is possible to prevent a situation in which the display mode is not changed for a while. Then, as shown in FIG. 29 (F), the second effect symbol EZb is stopped and displayed in, for example, the loss mode "971" while the fourth background image HK4 is displayed.

After that, it is assumed that the background change condition is satisfied when the variation effect is newly started. In this case, the change of the background image is determined by lottery so that the probability (transition rate) of being changed to the third background image HK3, which is the same second effect symbol group, is high (FIG. 48 (B). )reference). Therefore, it is decided to change to the third background image HK3. Further, in this case, since the second effect symbol EZb is to be displayed while the third background image HK3 is being displayed (see FIG. 48 (B)), the display mode of the effect symbol EZ should not be changed. become.

As a result, as shown in FIG. 29 (G), the display screen 50a is switched to the display of the third background image HK3, and the variable display of the second effect symbol EZb is started. In this way, although the background aspect of the background image is changed, the display aspect of the effect symbol EZ is not changed, so that it is possible to prevent the effect symbol EZ from being excessively changed. Then, as shown in FIG. 29 (H), the second effect symbol EZb is stopped and displayed in, for example, the loss mode "917" while the third background image HK3 is displayed.

After that, it is assumed that the background change condition is satisfied when the variation effect is newly started. However, in this case, the background image immediately before being changed to the current background image (third background image HK3) is another background image (fourth background) in the same effect symbol group (second effect symbol group). Image HK4). Therefore, from the background images other than the current third background image HK3 and the immediately preceding fourth background image HK4 (first background image HK1, second background image HK2, fifth background image HK5, sixth background image HK6). , The background image to be changed will be decided by lottery (see FIG. 47 (A)). Therefore, at this time, it is determined that the background image is changed to the fifth background image HK5. In this case, since the third effect symbol EZc is to be displayed while the fifth background image HK5 is displayed (see FIG. 47 (A)), the second effect symbol EZb is changed to the third effect symbol EZc. It will be changed.

As a result, as shown in FIG. 29 (I), the display screen 50a is switched to the display of the fifth background image HK5, and the variable display of the third effect symbol EZc is started. In this way, if the display mode of the effect symbol EZ is not changed by the previous background change (change of the background image), the display mode of the effect symbol EZ will always be changed in this background change, and the effect symbol EZ will be changed. It is possible to prevent a situation in which the display mode is not changed for a while. Then, as shown in FIG. 29 (J), the third effect symbol EZc is stopped and displayed in, for example, the loss mode "719" while the fifth background image HK5 is displayed.

7. Operation of the effect control microcomputer 121 [Sub-control main process] Next, the operation of the effect control microcomputer 121 will be described with reference to FIGS. 30 to 43. The counter, timer, flag, status, buffer, etc. that appear in the operation description of the effect control microcomputer 121 are provided in the effect RAM 124. When the power of the pachinko gaming machine PY1 is turned on, the effect control microcomputer 121 provided on the effect control board 120 reads out and executes the sub-control main processing program shown in FIG. 30 from the effect ROM 123. As shown in the figure, in the sub-control main process, the CPU initialization process is first performed (S4001). In the CPU initialization process (S4001), stack setting, constant setting, effect CPU 122 setting, SIO, PIO, CTC (circuit for managing interrupt time) and the like are set.

Subsequently, it is determined whether or not the power cutoff signal is ON and the contents of the effect RAM 124 are normal (S4002). If the determination result is NO, the effect RAM 124 is initialized (S4003), and the process proceeds to step S4004. On the other hand, if the determination result is YES (YES in S4002), the process proceeds to step S4004 without initializing the effect RAM 124. That is, if the power cutoff signal is not ON, or if the contents of the production RAM 124 are not normal even if the power cutoff signal is ON (NO in S4002), the production RAM 124 is initialized, but the power cutoff signal is caused by a power failure or the like. Is turned on, but if the contents of the effect RAM 124 are kept normal (YES in S4002), the effect RAM 124 is not initialized. If the effect RAM 124 is initialized, the values of various flags, statuses, counters, and the like are reset. Further, these steps S4001 to S4003 are executed only once after the power is turned on, and are not executed after that.

In step S4004, interrupts are disabled. Next, the random number seed update process is executed (S4005). In the random number seed update process (S4005), the values of various random number counters for determining the effect are updated. The random numbers for determining the effect include a random number for determining the effect symbol for determining the effect symbol EZ, a random number for determining the variable effect pattern lottery for determining the variable effect pattern, and a random number for determining the advance notice effect for determining various advance notice effects. And so on. The random number update method can be the same as the random number update process performed by the game control board 100 described above. Instead of adding the random values by 1 at the time of updating, it may be added by 2 or the like. This also applies to the random number update process performed by the game control board 100 described above.

When the random number seed update process (S4005) is completed, the command transmission process is executed (S4006). In the command transmission process (S4006), various commands stored in the output buffer in the effect RAM 124 of the effect control board 120 are transmitted to the image control board 140. Upon receiving the command, the image control board 140 executes various effects (variation effect, opening effect associated with the jackpot game, round effect, ending effect, etc.) using the image display device 50 according to the command. As the image control board 140 executes various effects, the effect control board 120 outputs sound from the speaker 620 via the sound control board 161 and outputs the sound from the speaker 620 via the sub drive board 162, and the panel lamp 54 and the frame lamp via the sub drive board 162. The 212 is made to emit light, and the board movable body 55k is driven. The effect control microcomputer 121 subsequently enables interrupts (S4007). After that, steps S4004 to S4007 are looped. While the interrupt is enabled, the receive interrupt process (S4008), the 1 ms timer interrupt process (S4009), and the 10 ms timer interrupt process (S4010) can be executed.

[Reception interrupt processing] The reception interrupt processing (S4008) is performed based on the fact that the strobe signal (STB signal) sent from the game control board 100 is input to the external INT input unit of the effect control microcomputer 121. That is, the reception interrupt processing (S4008) is not performed unless the strobe signal is input to the external INT input unit of the effect control microcomputer 121. As shown in FIG. 31, in the reception interrupt processing (S4008), various commands transmitted from the game control board 100 are stored in the reception buffer of the effect RAM 124 (S4101). This receive interrupt process (S4008) is a process that is executed in preference to other interrupt processes (S4009, S4010).

[1 ms timer interrupt process] The 1 ms timer interrupt process (S4009) is executed every time an interrupt pulse having a 1 msec cycle is input to the effect control board 120. As shown in FIG. 32, in the 1 ms timer interrupt process (S4009), first, the input process (S4201) is performed. In the input process (S4201), switch data (edge data and level data) are created based on the detection signals from the input unit detection sensor 40a (see FIG. 7) and the select button detection sensor 42a.

Subsequently, the lamp data output process (S4202) is performed. In the lamp data output processing (S4202), the lamp data created by the other processing (S4305) in the 10ms timer interrupt processing (S4010) described later is used as a sub drive in order to make the board lamp 54 and the frame lamp 212 emit light at the timing suitable for the production. Output to the board 162. That is, the panel lamp 54 and the frame lamp 212 are made to emit light in a predetermined light emitting mode according to the lamp data.

Next, drive control processing is performed (S4203). In the drive control process (S4203), drive data (board movable body drive data) is created and output in order to drive the board movable body 55k at a timing that matches the effects such as SP reach and jackpot production. That is, the board movable body 55k is driven in a predetermined operation mode according to the drive data.

After the drive control process (S4203), the watchdog timer process (S4204) for resetting the watchdog timer is performed, and this process is completed.

[10 ms timer interrupt process] The 10 ms timer interrupt process (S4010) is executed every time an interrupt pulse having a cycle of 10 msec is input to the effect control board 120. As shown in FIG. 33, in the 10 ms timer interrupt process (S4010), first, the received command analysis process described later is performed (S4301).

Subsequently, a switch state acquisition process is performed in which the switch data created in the input process (S4201) of the 1 ms timer interrupt process (S4009) is stored in the effect RAM 124 as the switch data for the 10 ms timer interrupt process (S4302). Then, a switch process for setting the display contents of the display screen 50a based on the switch data stored in the switch state acquisition process (S4302) is performed (S4303).

Subsequently, voice control processing (S4304) is performed. In the voice control process (S4304), voice data (data for controlling the output of voice from the speaker 620) is created, output to the image control board 140, and time management of voice production is performed. As a result, the sound suitable for the effect to be executed is output from the speaker 620. Then, other processing such as updating random numbers for various effects is executed (S4305), and this processing is completed.

[Received command analysis process] As shown in FIG. 34, in the received command analysis process (S4301), the effect control microcomputer 121 first determines whether or not a game state designation command has been received from the game control board 100 (S4401). ), If it is received, the mode status setting process is performed (S4402). In the mode status setting process (S4402), the received game state specification command is analyzed, and the mode status value is set based on the game state information included in the game state specification command. The value of the mode status is set to "1" in the normal gaming state, set to "2" in the high accuracy high base state, and set to "3" in the low accuracy time saving state. In this way, the effect control microcomputer 121 can grasp the game state at the present time.

Subsequently, the effect control microcomputer 121 determines whether or not a fluctuation start command (special figure 1 fluctuation start command or special figure 2 fluctuation start command) has been received from the game control board 100 (S4403), and if so, has received it. The variable effect start processing described later is performed (S4404).

Subsequently, the effect control microcomputer 121 determines whether or not a fluctuation stop command (special figure 1 fluctuation stop command or special figure 2 fluctuation stop command) has been received from the game control board 100 (S4405), and if so, has received it. Performs variable effect end processing (S4406). In the variation effect end process (S4406), the variation stop command is analyzed, and the variation effect end command for ending the variation effect is set in the output buffer of the effect RAM 124 based on the analysis result.

Subsequently, the effect control microcomputer 121 determines whether or not an opening command has been received from the game control board 100 (S4407), and if so, performs an opening effect selection process (S4408). In the opening effect selection process (S4408), the opening command is analyzed, and the pattern (content) of the opening effect to be executed during the opening of the jackpot game is selected based on the analysis result. Then, an opening effect start command for starting the opening effect with the selected opening effect pattern is set in the output buffer of the effect RAM 124. Subsequently, after the opening effect selection process (S4408), the value of the variable effect counter is reset to "0" (S4409), and the process proceeds to step S4410. As will be described later, the variation effect counter is for counting the number of times the variation effect is executed after the background image is changed in the normal gaming state. In this way, the value of the variable effect counter is reset to "0" at the start of the opening effect (big hit effect).

Subsequently, the effect control microcomputer 121 determines whether or not a round designation command has been received from the game control board 100 (S4410), and if so, performs a round effect selection process (S4411). In the round effect selection process (S4411), the round designation command is analyzed, and the pattern (content) of the round effect to be executed during the round game of the jackpot game is selected based on the analysis result. Then, a round effect start command for starting the round effect with the selected round effect pattern is set in the output buffer of the effect RAM 124.

Subsequently, the effect control microcomputer 121 determines whether or not an ending command has been received from the game control board 100 (S4412), and if so, performs an ending effect selection process (S4413). In the ending effect selection process (S4413), the ending command is analyzed, and the pattern (content) of the ending effect to be executed during the ending of the jackpot game is selected based on the analysis result. Then, an ending effect start command for starting the ending effect with the selected ending effect pattern is set in the output buffer of the effect RAM 124.

Subsequently, the effect control microcomputer 121 performs other processes (S4414) such as processes based on reception commands other than the above commands (for example, processes for performing customer wait effects based on the reception of customer wait commands, and normal symbol fluctuations. The process for performing the normal map fluctuation effect based on the reception of the start command) is performed, and the reception command analysis process (S4301) is completed.

[Variation effect start process] As shown in FIG. 35, in the variation effect start process (S4404), the effect control microcomputer 121 first analyzes the variation start command (S4501). The fluctuation start command includes information on the special figure stop symbol data set in the special figure 1 jackpot determination process and the special figure 2 jackpot determination process (see FIG. 20), the special figure 1 variation pattern selection process, and the special figure 2 variation pattern. Information on the fluctuation pattern set in the selection process (see FIGS. 21 and 22), information for designating the current gaming state, and the like are included. It should be noted that the information acquired by the effect control microcomputer 121 here can be appropriately used in the processing to be executed thereafter. Next, the effect control microcomputer 121 refers to the value of the mode status currently set (S4502).

Subsequently, the effect control microcomputer 121 executes a variable effect pattern selection process (S4503). Once the variable effect pattern is decided, the time of the variable effect, the presence or absence of the reach effect, the content of the reach effect, the presence or absence of the SP reach, the content of the SP reach, the presence or absence of the effect button effect (SW effect), the content of the effect button effect, and the effect development. The details of the content of the variable production consisting of the composition etc. will be decided.

Subsequently, the effect control microcomputer 121 executes a background image selection process described later (S4504). Since the display mode of the effect symbol EZ in the normal gaming state is associated with the background mode of the background image (each background image from the first background image HK1 to the sixth background image HK6), the background image selection process (S4504). ) Determines the type of the effect symbol EZ in the normal gaming state. Then, in the variable effect, the effect symbols EZ1, EZ2, and EZ3 to be finally stopped and displayed are selected (S4505). Specifically, a random number for determining the effect symbol is acquired, and one table is selected from a plurality of tables classified according to the presence or absence of reach, etc., based on the analysis result of the fluctuation start command. Then, by using the selected table to determine the acquired random number for determining the effect symbol, the combination of the numbers of the effect symbols EZ1, EZ2, and EZ3 to be finally stopped and displayed is selected.

Subsequently, the effect control microcomputer 121 executes the advance notice effect selection process (S4506). In the advance notice effect selection process (S4506), a random number for determining the advance notice effect is acquired, and one table is selected from a plurality of tables classified according to the presence or absence of reach based on the analysis result of the fluctuation start command. do. The advance notice effect is selected by determining the acquired random number for determining the advance notice effect using the selected table. As a result, the content of the notice effect such as the so-called step-up notice effect and the chance-up notice effect is determined.

Subsequently, the effect control microcomputer 121 sets the variation effect start command for starting the selected variation effect pattern, the effect symbol EZ, and the advance notice effect in the output buffer of the effect RAM 124 (S4507), and ends this process. .. When the variation effect start command set in step S4507 is transmitted to the image control board 140 by the command transmission process (S4006), the variation effect synchronized with the variation display of the special symbol is started on the display screen 50a. That is, as shown in FIG. 29, it is possible to execute a variable effect accompanied by a change in the background aspect of the background image and a change in the display aspect of the effect symbol EZ.

[Background image selection process] As shown in FIG. 36, in the background image selection process (S4504), the effect control microcomputer 121 first determines whether or not the mode status value is “1” (S4601). If it is not "1" (NO in S4601), a background image different from each background image from the first background image HK1 to the sixth background image HK6 is displayed because it is in a high-accuracy time-saving state or a low-accuracy time-saving state. become. Therefore, in this case, the process proceeds to step S4619, another background image selection process is executed, and this process is completed.

On the other hand, if the value of the mode status is "1" (YES in S4601), the value of the fluctuation effect counter is increased by "1" (S4602), and the process proceeds to step S4603. In this way, the value of the variation effect counter is incremented by 1 each time the variation effect is started in the normal gaming state. In step S4603, it is determined whether or not the value of the fluctuation effect counter is "20" or more. If it is less than "20" (NO in S4603), it is assumed that the background change condition has not been satisfied yet, and this process is terminated. On the other hand, if the value of the fluctuation effect counter is "20" or more (YES in S4603), then the background change execution lottery process is executed (S4604), and the process proceeds to step S4605.

In the background change execution lottery process (S4604), the background change random number is acquired, and the acquired background change random number is determined using the background change execution lottery table shown in FIG. This determines whether or not to change the background image (background change), that is, whether or not the background change condition is satisfied. In step S4605, it is determined whether or not the execution of the background change is decided, and if the execution is not decided (NO in S4605), this process ends. On the other hand, if the execution is decided (YES in S4605), the value of the fluctuation effect counter is reset to "0" (S4606), and the process proceeds to step S4607 shown in FIG. 37.

Here, as shown in FIG. 37, when the effect control microcomputer 121 proceeds to step S4607, any one of the six processes related to the change of the background image according to the type of the background image currently displayed is performed. Run. The background flag indicates "1" when the background image currently displayed is the first background image HK1, "2" when the background image is the second background image HK2, and is the third background image HK3. In the case, "3" is shown, when the fourth background image is HK4, "4" is shown, when the fifth background image is HK5, "5" is shown, and when the sixth background image is HK6, "6" is shown. Is shown.

Therefore, when the background flag is "1" (YES in S4607), the first background change process for changing from the current first background image HK1 to another background image is executed (S4608). Proceed to step S4618. If the background flag is "2" (NO for S4607, YES for S4609), the second background change process for changing from the current second background image HK2 to another background image is executed (). S4610), proceed to step S4618. If the background flag is "3" (NO for S4607, NO for S4609, YES for S4611), the third background change process for changing from the current third background image HK3 to another background image is performed. Execute (S4612) and proceed to step S4618. If the background flag is "4" (NO for S4607, NO for S4609, YES for S4613), the fourth background image HK4 at the present time is changed to another background image. Execute the background change process (S4614), and proceed to step S4618. If the background flag is "5" (NO for S4607, NO for S4609, NO for S4613, YES for S4615), change from the current 5th background image HK5 to another background image. The fifth background change process for this is executed (S4616), and the process proceeds to step S4618. If the background flag is "5" (NO for S4607, NO for S4609, NO for S4613, NO for S4615), change from the current 6th background image HK6 to another background image. 6th background change process for this is executed (S4617), and the process proceeds to step S4618. The value of the background flag is set to "1" by default.

In step S4618, a background change command including background image information (background flag value information) determined by any of the background change processes from the first background change process (S4608) to the sixth background change process (S4617) is executed. This process is completed by setting it in the output buffer of the effect RAM 124. In this way, the background change command set in step S4618 is transmitted to the image control board 140, and the variation effect start command (see FIG. 35) set in step S4507 is transmitted to the image control board 140 as described above. As a result, the variable effect is executed while the changed background image is displayed. Further, when the changed background image is a background image in a different effect symbol group (see FIG. 28), the variable effect is executed by the changed effect symbol EZ.

[First Background Change Process] As shown in FIG. 38, in the first background change process (S4608), the effect control microcomputer 121 first determines whether or not the value of the previous background flag is "2" (1st background change process). S5101). Here, the previous background flag indicates the information of the background image displayed immediately before the background image currently displayed. Specifically, the previous background flag indicates "1" if the background image displayed immediately before is the first background image HK1, "2" if the background image is the second background image HK2, and the third background image HK3. If, it indicates "3", if it is the fourth background image HK4, it indicates "4", if it is the fifth background image HK5, it indicates "5", and if it is the sixth background image HK6, it indicates "6". It has become like.

In step S5101, if the background flag was "2" last time (YES in S5101), the background image is changed from the first background image HK1, but the background displayed before the first background image HK1. It means that the image was the second background image HK2, which is the same first effect symbol group (see FIG. 28). Therefore, in this case, the process proceeds to step S5102, the background image after the change is determined by lottery using the first background change special table shown in FIG. 45 (A), and the process proceeds to step S5104. Specifically, in step S5102, the background change random number is acquired, and the acquired background change random number is determined using the first background change special table shown in FIG. 45 (A), whereby the third background image HK3 and the fourth background image HK3 and the fourth. The changed background image is determined from the background image HK4, the fifth background image HK5, and the sixth background image HK6. This makes it possible to prevent the image from returning to the second background image HK2 that was displayed immediately before the first background image HK1. Further, it is possible to always switch from the display of the first effect symbol EZa to the display of the second effect symbol EZb or the display of the third effect symbol EZc, and it is possible to prevent the first effect symbol EZa from being continuously displayed. Is.

On the other hand, in step S5101, if the previous background flag is not "2" (NO in S5101), the background image displayed before the first background image HK1 is the same first effect symbol group (see FIG. 28). It means that it wasn't there. Therefore, in this case, the process proceeds to step S5103, the background image after the change is determined by lottery using the first background change normal table shown in FIG. 45 (B), and the process proceeds to step S5104. Specifically, in step S5103, the second background image HK2 and the third background image HK2 are obtained by acquiring the background change random number and determining the acquired background change random number using the first background change normal table shown in FIG. 45 (B). The changed background image is determined from the background image HK3, the fourth background image HK4, the fifth background image HK5, and the sixth background image HK6. Here, as is clear from FIG. 45 (B), the probability (transition rate) that the second background image HK2, which is the same first effect symbol group as the first background image HK1, is determined by lottery is very high (60%). To) is set. This makes it possible to easily change from the first background image HK1 to the second background image HK2. Then, by making the first effect symbol EZa continue to be displayed even after switching to the second background image HK2, it is possible to prevent the display mode of the effect symbol EZ from being switched immediately.

In step S5104, the value of the background flag is set based on the drawn background image, and the process proceeds to step S5105. For example, if the lottery background image is the second background image HK2, the value of the background flag is set to "2". Then, in step S5105, the value of the previous background flag is set to "1", and the first background change process (S4608) is completed.

[Second Background Change Process] As shown in FIG. 39, in the second background change process (S4610), the effect control microcomputer 121 first determines whether or not the value of the previous background flag is "1" (1). S5201). If the background flag was "1" last time (YES in S5201), the background image is changed from the second background image HK2, but the background image displayed before the second background image HK2 is the same. It means that it was the first background image HK1 which is one effect symbol group (see FIG. 28). Therefore, in this case, the process proceeds to step S5202, the background image after the change is determined by lottery using the second background change special table shown in FIG. 46 (A), and the process proceeds to step S5204. Specifically, in step S5202, the background change random number is acquired, and the acquired background change random number is determined using the second background change special table shown in FIG. 46 (A), whereby the third background image HK3 and the fourth background image HK3 and the fourth. The changed background image is determined from the background image HK4, the fifth background image HK5, and the sixth background image HK6. This makes it possible to prevent the image from returning to the first background image HK1 displayed immediately before the second background image HK2. Further, it is possible to always switch from the display of the first effect symbol EZa to the display of the second effect symbol EZb or the display of the third effect symbol EZc, and it is possible to prevent the first effect symbol EZa from being continuously displayed. Is.

On the other hand, in step S5201, if the previous background flag is not "1" (NO in S5201), the background image displayed before the second background image HK2 is the same in the first effect symbol group (see FIG. 28). It means that it wasn't there. Therefore, in this case, the process proceeds to step S5203, the background image after the change is determined by lottery using the second background change normal table shown in FIG. 46 (B), and the process proceeds to step S5204. Specifically, in step S5203, the first background image HK1 and the third background image HK1 are obtained by acquiring the background change random number and determining the acquired background change random number using the second background change normal table shown in FIG. 46 (B). The changed background image is determined from the background image HK3, the fourth background image HK4, the fifth background image HK5, and the sixth background image HK6. Here, as is clear from FIG. 46 (B), the probability (transition rate) that the first background image HK1, which is the same first effect symbol group as the second background image HK2, is determined by lottery is very high (60%). To) is set. This makes it possible to easily change from the second background image HK2 to the first background image HK1. Then, by making the first effect symbol EZa continue to be displayed even after switching to the first background image HK1, it is possible to prevent the display mode of the effect symbol EZ from being switched immediately.

In step S5204, the value of the background flag is set based on the drawn background image, and the process proceeds to step S5205. Then, in step S5205, the value of the previous background flag is set to "2", and the second background change process (S4610) is completed.

[Third background change process] As shown in FIG. 40, in the third background change process (S4612), the effect control microcomputer 121 first determines whether or not the value of the previous background flag is "4" ("3". S5301). If the background flag was "4" last time (YES in S5301), the background image is changed from the third background image HK3, but the background image displayed before the third background image HK3 is the same. It means that it was the 4th background image HK4 which is the 2 effect symbol group (see FIG. 28). Therefore, in this case, the process proceeds to step S5302, the background image after the change is determined by lottery using the third background change special table shown in FIG. 47 (A), and the process proceeds to step S5304. Specifically, in step S5302, the first background image HK1 and the second background image HK1 are obtained by acquiring the background change random number and determining the acquired background change random number using the third background change special table shown in FIG. 47 (A). The changed background image is determined from the background image HK2, the fifth background image HK5, and the sixth background image HK6. This makes it possible to prevent the image from returning to the fourth background image HK4, which was displayed immediately before the third background image HK3. Further, it is possible to always switch from the display of the second effect symbol EZb to the display of the first effect symbol EZa or the display of the third effect symbol EZc, and it is possible to prevent the second effect symbol EZb from being continuously displayed. Is.

On the other hand, in step S5301, if the previous background flag is not "4" (NO in S5301), the background image displayed before the third background image HK3 is the same in the second effect symbol group (see FIG. 28). It means that it wasn't there. Therefore, in this case, the process proceeds to step S5303, the background image after the change is determined by lottery using the third background change normal table shown in FIG. 47 (B), and the process proceeds to step S5304. Specifically, in step S5303, the first background image HK1 and the second background image HK1 are obtained by acquiring the background change random number and determining the acquired background change random number using the third background change normal table shown in FIG. 47 (B). The changed background image is determined from the background image HK2, the fourth background image HK4, the fifth background image HK5, and the sixth background image HK6. Here, as is clear from FIG. 47 (B), the probability (transition rate) that the fourth background image HK4, which is the same second effect symbol group as the third background image HK3, is determined by lottery is very high (60%). To) is set. This makes it possible to easily change from the third background image HK3 to the fourth background image HK4. Then, by making the second effect symbol EZb continue to be displayed even after switching to the fourth background image HK4, it is possible to prevent the display mode of the effect symbol EZ from being switched immediately.

In step S5304, the value of the background flag is set based on the drawn background image, and the process proceeds to step S5305. Then, in step S5305, the value of the previous background flag is set to "3", and the third background change process (S4612) is completed.

[Fourth Background Change Process] As shown in FIG. 41, in the fourth background change process (S4614), the effect control microcomputer 121 first determines whether or not the value of the previous background flag is "3" ( S5401). If the background flag was "3" last time (YES in S5401), the background image is changed from the 4th background image HK4, but the background image displayed before the 4th background image HK4 is the same. It means that it was the third background image HK3 which is the 2 effect symbol group (see FIG. 28). Therefore, in this case, the process proceeds to step S5402, the background image after the change is determined by lottery using the fourth background change special table shown in FIG. 48 (A), and the process proceeds to step S5404. Specifically, in step S5402, the first background image HK1 and the second background image HK1 are obtained by acquiring the background change random number and determining the acquired background change random number using the fourth background change special table shown in FIG. 48 (A). The changed background image is determined from the background image HK2, the fifth background image HK5, and the sixth background image HK6. This makes it possible to prevent the image from returning to the third background image HK3 that was displayed immediately before the fourth background image HK4. Further, it is possible to always switch from the display of the second effect symbol EZb to the display of the first effect symbol EZa or the display of the third effect symbol EZc, and it is possible to prevent the second effect symbol EZb from being continuously displayed. Is.

On the other hand, in step S5401, if the previous background flag is not "3" (NO in S5401), the background image displayed before the fourth background image HK4 is the same in the second effect symbol group (see FIG. 28). It means that it wasn't there. Therefore, in this case, the process proceeds to step S5403, the background image after the change is determined by lottery using the fourth background change normal table shown in FIG. 48 (B), and the process proceeds to step S5404. Specifically, in step S5403, the first background image HK1 and the second background image HK1 are obtained by acquiring the background change random number and determining the acquired background change random number using the fourth background change normal table shown in FIG. 48 (B). The changed background image is determined from the background image HK2, the third background image HK3, the fifth background image HK5, and the sixth background image HK6. Here, as is clear from FIG. 48 (B), the probability (transition rate) that the third background image HK3, which is the same second effect symbol group as the fourth background image HK4, is determined by lottery is very high (60%). To) is set. This makes it possible to easily change from the fourth background image HK4 to the third background image HK3. Then, by making the second effect symbol EZb continue to be displayed even after switching to the third background image HK3, it is possible to prevent the display mode of the effect symbol EZ from being switched immediately.

In step S5404, the value of the background flag is set based on the drawn background image, and the process proceeds to step S5405. Then, in step S5405, the value of the previous background flag is set to "4", and the fourth background change process (S4614) is completed.

[Fifth Background Change Process] As shown in FIG. 42, in the fifth background change process (S4616), the effect control microcomputer 121 first determines whether or not the value of the previous background flag is "6" (6). S5501). If the background flag was "6" last time (YES in S5501), the background image is changed from the 5th background image HK5, but the background image displayed before the 5th background image HK5 is the same. It means that it was the sixth background image HK6 which is the 3 effect symbol group (see FIG. 28). Therefore, in this case, the process proceeds to step S5502, the background image after the change is determined by lottery using the fifth background change special table shown in FIG. 49 (A), and the process proceeds to step S5504. Specifically, in step S5502, the first background image HK1 and the second background image HK1 are obtained by acquiring the background change random number and determining the acquired background change random number using the fifth background change special table shown in FIG. 49 (A). The changed background image is determined from the background image HK2, the third background image HK3, and the fourth background image HK4. This makes it possible to prevent the image from returning to the sixth background image HK6, which was displayed immediately before the fifth background image HK5. Further, it is possible to always switch from the display of the third effect symbol EZc to the display of the first effect symbol EZa or the display of the second effect symbol EZb, and it is possible to prevent the third effect symbol EZc from being continuously displayed. Is.

On the other hand, in step S5501, if the background flag was not "6" last time (NO in S5501), the background image displayed before the fifth background image HK5 is the same in the third effect symbol group (see FIG. 28). It means that it wasn't there. Therefore, in this case, the process proceeds to step S5503, the background image after the change is determined by lottery using the fifth background change normal table shown in FIG. 49 (B), and the process proceeds to step S5504. Specifically, in step S5503, the first background image HK1 and the second background image HK1 are obtained by acquiring the background change random number and determining the acquired background change random number using the fifth background change normal table shown in FIG. 49 (B). The changed background image is determined by lottery from the background image HK2, the third background image HK3, the fourth background image HK4, and the sixth background image HK6. Here, as is clear from FIG. 49 (B), the probability (transition rate) that the sixth background image HK6, which is the same third effect symbol group as the fifth background image HK5, is determined by lottery is very high (60%). To) is set. This makes it possible to easily change from the fifth background image HK5 to the sixth background image HK6. Then, by making the third effect symbol EZc continue to be displayed even after switching to the sixth background image HK6, it is possible to prevent the display mode of the effect symbol EZ from being switched immediately.

In step S5504, the value of the background flag is set based on the drawn background image, and the process proceeds to step S5505. Then, in step S5505, the value of the previous background flag is set to "5", and the fifth background change process (S4616) is completed.

[Sixth Background Change Process] As shown in FIG. 43, in the sixth background change process (S4617), the effect control microcomputer 121 first determines whether or not the value of the previous background flag is "5" (6th background change process). S5601). If the background flag was "5" last time (YES in S5601), the background image is changed from the 6th background image HK6, but the background image displayed before the 6th background image HK6 is the same. It means that it was the fifth background image HK5, which is the three effect symbol group (see FIG. 28). Therefore, in this case, the process proceeds to step S5602, the background image after the change is determined by lottery using the sixth background change special table shown in FIG. 50 (A), and the process proceeds to step S5604. Specifically, in step S5602, the first background image HK1 and the second background image HK1 are obtained by acquiring the background change random number and determining the acquired background change random number using the sixth background change special table shown in FIG. 50 (A). The changed background image is determined from the background image HK2, the third background image HK3, and the fourth background image HK4. This makes it possible to prevent the user from returning to the fifth background image HK5, which was displayed immediately before the sixth background image HK6. Further, it is possible to always switch from the display of the third effect symbol EZc to the display of the first effect symbol EZa or the display of the second effect symbol EZb, and it is possible to prevent the third effect symbol EZc from being continuously displayed. Is.

On the other hand, in step S5601, if the background flag was not "6" last time (NO in S5601), the background image displayed before the sixth background image HK6 is the same in the third effect symbol group (see FIG. 28). It means that it wasn't there. Therefore, in this case, the process proceeds to step S5603, the background image after the change is determined by lottery using the sixth background change normal table shown in FIG. 50 (B), and the process proceeds to step S5604. Specifically, in step S5603, the first background image HK1 and the second background image HK1 are obtained by acquiring the background change random number and determining the acquired background change random number using the sixth background change normal table shown in FIG. 50 (B). The changed background image is determined by lottery from the background image HK2, the third background image HK3, the fourth background image HK4, and the fifth background image HK5. Here, as is clear from FIG. 50 (B), the probability (transition rate) that the fifth background image HK5, which is the same third effect symbol group as the sixth background image HK6, is determined by lottery is very high (60%). To) is set. This makes it possible to easily change from the sixth background image HK6 to the fifth background image HK5. Then, by making the third effect symbol EZc continue to be displayed even after switching to the fifth background image HK5, it is possible to prevent the display mode of the effect symbol EZ from being switched immediately.

In step S5604, the value of the background flag is set based on the drawn background image, and the process proceeds to step S5605. Then, in step S5605, the value of the previous background flag is set to "6", and the sixth background change process (S4617) is completed.

8. Effect of the present embodiment As described in detail above, according to the pachinko gaming machine PY1 of the present embodiment, the first background image HK1 is easily changed to the second background image HK2 (see FIG. 45B). Then, the first background image HK1 is not changed to the first background image HK1 again through the second background image HK2 (see FIG. 45 (A)). That is, it is easy to be changed to any one of the third background image HK3, the fourth background image HK4, the fifth background image HK5, and the sixth background image HK6 via the first background image HK1 and the second background image HK2. In this way, it is possible to make it difficult to return to the first background image HK1 immediately after changing from the first background image HK1. As a result, it is possible to make it difficult for the player to see the same background image, and it is possible to enhance the interest of the production.

Further, according to the pachinko gaming machine PY1 of the present embodiment, for example, after the first background image HK1 is changed to the third background image HK3 via the second background image HK2, the third background image HK3 is changed to the first background image HK1. It is easier to change from the third background image HK3 to the fourth background image HK4 than when it is changed (see FIG. 47 (B)). Therefore, it is possible to make it more difficult for the background image to immediately return to the first background image HK1 after being changed from the first background image HK1.

Further, according to the pachinko gaming machine PY1 of the present embodiment, even if the first background image HK1 is changed to the second background image HK2, the effect symbol EZ remains the first effect symbol EZa, and the display mode of the effect symbol EZ is changed. Not going to change. After that, when the second background image HK2 is changed to any one of the third background image HK3, the fourth background image HK4, the fifth background image HK5, and the sixth background image HK6, the second effect symbol EZb or the second 3 Change to one of the production symbols EZc. That is, the display mode of the effect symbol EZ is always changed. In this way, by changing the background aspect of the background image, it is possible to appropriately change the display aspect of the effect symbol EZ, and it is possible to make the effect symbol EZ less likely to get bored.

Further, according to the pachinko gaming machine PY1 of the present embodiment, when the background image is changed from the first background image HK1 to the second background image HK2, the effect symbol EZ remains unchanged as the first effect symbol EZa (FIG. 28). reference). On the other hand, when the background image is changed from the first background image HK1 to the third background image HK3, the effect symbol EZ is changed from the first effect symbol EZa to the second effect symbol EZb (see FIG. 28). In this way, by changing the display mode of the background image, it is possible to appropriately show the change in the display mode of the effect symbol EZ, and it is possible to enhance the interest of the effect.

Further, according to the pachinko gaming machine PY1 of the present embodiment, when changing from the first background image HK1, the first background image HK1 to the first background image HK1 is higher than when changing from the first background image HK1 to, for example, the third background image HK3. 2 It is easy to change to the background image HK2 (see FIG. 45 (B)). That is, the change from the first background image HK1 is more likely to remain as the first effect symbol EZa than when the first effect symbol EZa is changed to the second effect symbol EZb. In this way, by changing the background image, it is possible to avoid excessively changing the display mode of the effect symbol EZ and to show the display mode of the same effect symbol EZ to some extent.

Further, according to the pachinko gaming machine PY1 of the present embodiment, after the first background image HK1 is changed to the second background image HK2, the second background image HK2 does not return to the first background image HK1 again. It is changed to any one of the third background image HK3, the fourth background image HK4, the fifth background image HK5, and the sixth background image HK6 (see FIG. 45 (A)). Therefore, at this time, the effect symbol EZ is always changed from the first effect symbol EZa. That is, if the background mode is changed twice from the first background image HK1, the display mode of the effect symbol EZ is changed at least once. In this way, it is possible to prevent the first effect symbol EZa from being continuously displayed, to appropriately change the display mode of the effect symbol EZ, and to make the effect symbol EZ less likely to get bored.

Further, according to the pachinko gaming machine PY1 of the present embodiment, for example, when the first background image HK1 or the second background image HK2 is changed to the third background image HK3, the effect symbol EZ is changed from the first effect symbol EZa to the second effect symbol. It is changed to EZb (see FIG. 28). After that, when the background image is changed from the third background image HK3, it is more likely to be changed to the fourth background image HK4 than when the background image is changed to the first background image HK1 or the second background image HK2 (FIG. 47 (B). )), The effect symbol EZ does not change and tends to remain as the second effect symbol EZb. Therefore, it is possible to prevent a situation in which the display mode of the effect symbol EZ is changed again immediately after the display mode is changed from the first effect symbol EZa to the second effect symbol EZb, and the display mode is the same. It is possible to make the design EZ look appropriate.

Further, according to the pachinko gaming machine PY1 of the present embodiment, after the third background image HK3 is changed to the fourth background image HK4, the fourth background image HK4 does not return to the third background image HK3 again. It is changed to any one of the first background image HK1, the second background image HK2, the fifth background image HK5, and the sixth background image HK6 (see FIG. 48 (A)). Therefore, at this time, the effect symbol EZ is always changed from the second effect symbol EZb. That is, if the background mode is changed twice from the third background image HK3, the display mode of the effect symbol EZ is changed at least once. In this way, if the background aspect is changed twice from the second background image HK2, the display aspect of the effect symbol EZ is changed at least once. Therefore, it is possible to appropriately change the display mode of the effect symbol EZ, and it is possible to make the effect symbol EZ less likely to get bored.

9. Modification example The modification example will be described below. In the description of the modified example, the same components as those of the pachinko gaming machine PY1 of the above-described embodiment are designated by the same reference numerals and the description thereof will be omitted. Of course, the configurations according to the modified examples may be appropriately combined and configured. Further, the technical features in the above-described embodiment and the following modified examples can be appropriately deleted unless they are described as essential in the present specification.

In the above embodiment, as shown in FIG. 28, the background aspect of the first background image HK1 (first background aspect) is a background aspect showing the scenery of the mountain in the daytime, and the background aspect of the second background image HK2 (second background aspect). The aspect) is a background aspect showing the scenery of the mountains at night, and the background aspect of the third background image HK3 (the third background aspect) is the background aspect showing the scenery of the city in the daytime, and the background aspect of the fourth background image HK4. (Fourth background aspect) was set as a background aspect showing the scenery of the city at night. However, the first background aspect, the second background aspect, the third background aspect, and the fourth background aspect are not limited to those described above, and show other landscapes, patterns, and colors (effects) such as seas, rivers, and deserts. It may be a background aspect and can be changed as appropriate.

In the above embodiment, as shown in FIG. 28, the display mode (first display mode) of the first effect symbol EZa is defined as a character reminiscent of the childhood of the main character, and the display mode of the second effect symbol EZb (first display mode). The second display mode) indicates a character reminiscent of the high school days of the main character, and the display mode (third display mode) of the third production symbol EZc indicates a character reminiscent of the professional age of the main character. did. However, the first display mode, the second display mode, and the third display mode are not limited to those described above, and may indicate, for example, a character before transformation, a character during transformation, a character after transformation, and the like. It can be changed as appropriate.

Further, in the above embodiment, as shown in FIG. 28, as the effect symbol group in which the display mode of the same effect symbol EZ is displayed, the first effect symbol group, the second effect symbol group, and the third effect symbol group are used. there were. However, the effect symbol group may be only one or two or four or more.

Further, in the above embodiment, as shown in FIG. 28, two background images are included in each of the first effect symbol group, the second effect symbol group, and the third effect symbol group. .. However, the number of background images included in the effect symbol group may be three or more, or may be one. For example, the background image included in the first effect symbol group is changed from the first background image HK1 to the second background image HK2 by setting the first background image HK1, the second background image HK2, and the third background image HK3. In any case, the display mode of the effect symbol EZ may not be changed (it remains the first effect symbol EZa) in any case where the first background image HK1 is changed to the third background image HK3. .. In this case, it is possible to suppress the frequent change of the effect symbol EZ with the change of the background image, as compared with the first form. The number of background images included in each effect symbol group does not have to be the same.

Further, in the above embodiment, as shown in FIG. 28, there are six background modes of the background image that are changed in the normal gaming state. That is, as the background image, there were a first background image HK1, a second background image HK2, a third background image HK3, a fourth background image HK4, a fifth background image HK5, and a sixth background image HK6. However, the background aspect of the background image that is usually changed in the gaming state may be 3, 4, 5, 7, or more. Then, the background mode of the background image may be changed not in the normal gaming state but in other gaming states (high-accuracy time-saving state, low-accuracy time-saving state, high-accuracy non-time-saving state).

Further, in the above embodiment, when the background image (background aspect) is changed after the first background image HK1 is changed to the second background image HK2, the background image (background mode) is not changed to the first background image HK1 (FIG. 45 (A)). reference). However, even when the background image is changed after the first background image HK1 is changed to the second background image HK2, the background image may be changed to the first background image HK1. In this case, it is preferable to set so that it is easier to change from the second background image HK2 to the third background image HK3 than to change from the second background image HK2 to the first background image HK1. More specifically, from the second background image HK, background images other than the first background image HK1 and the second background image HK2 (third background image HK3, fourth background image HK4, fifth background image HK5, and sixth background image). It is preferable that the total probability of being changed to HK6) is 50% or more. Even in this way, it is possible to make it difficult to return to the first background image HK1 immediately after passing through the first background image HK1 and the second background image HK2, and the same background image (first background image HK1) is given to the player. This is because it can be difficult to show.

Further, in the above embodiment, when the background image is changed from the first background image HK1, the first background image HK1 is changed to the second background image HK2 rather than the first background image HK1 is changed to the third background image HK3. It was easier to do (see FIG. 45 (B)). However, the probability of changing from the first background image HK1 to the third background image HK3 (transition rate) is the same as the probability of changing from the first background image HK1 to the second background image HK2 (transition rate), or the first. It may be higher than the probability of changing from the background image HK1 to the second background image HK2. In this case, it is easier to change from the first background image HK1 to the third background image HK3 than in the above embodiment, and it is possible to easily change the effect symbol EZ from the first effect symbol EZa to the second effect symbol EZb. It is possible. That is, it is possible to make it easier to change the display mode of the effect symbol EZ by changing the background mode of the background image.

Further, in the above embodiment, when the background image is changed from the third background image HK3, the third background image HK3 is changed to the fourth background image HK4 rather than the third background image HK3 is changed to the first background image HK1. It was easier to do (see FIG. 47 (B)). However, the probability of changing from the third background image HK3 to the first background image HK1 (transition rate) is the same as the probability of changing from the third background image HK3 to the fourth background image HK4 (transition rate), or the third. It may be higher than the probability of changing from the background image HK3 to the fourth background image HK4. In this case, it is easier to change from the third background image HK3 to the first background image HK1 than in the above embodiment, and it is possible to easily change the effect symbol EZ from the second effect symbol EZb to the first effect symbol EZa. It is possible. That is, it is possible to make it easier to change the display mode of the effect symbol EZ by changing the background mode of the background image.

Further, in the above embodiment, as shown in FIG. 28, when the background image (background mode) is changed and the background image is changed to a background image included in a different effect symbol group, the display mode of the effect symbol EZ (specific image) is changed. I did it. However, the display mode of the specific image to be changed with the change of the background image is not limited to the display mode of the effect symbol EZ, and can be changed as appropriate. For example, as the display mode of the specific image to be changed, the display mode of the hold icon HA (hold image), the display mode of the effect image, the display mode of the character image, the display mode of the item image, the display mode of the character image, and the display mode of the stock image. It may be a mode, a display mode of an image prompting the operation of the operation means, a display mode of a warning image such as fraud, a display mode of a cut-in notice image, a display mode of a step-up notice image, or the like.

Further, in the above embodiment, the background image includes a first background image HK1, a second background image HK2, a third background image HK3, a fourth background image HK4, a fifth background image HK5, and a sixth background image HK6. An embodiment when changing the image has been described. However, the background image in the embodiment is replaced with various production images such as a hold icon HA (hold image), an effect image, a character image, an item image, a character image, a stock image, and an image that encourages operation of an operation means. You may try to do it.

Further, in the above embodiment, as shown in FIG. 28, the background images on which the first effect symbol EZa is to be displayed are the first background image HK1 and the second background image HK2, and the second effect symbol EZb is displayed. The background images to be used were the third background image HK3 and the fourth background image HK4. However, the combination of the effect symbol and the background image can be changed as appropriate. For example, the background image on which the first effect symbol EZa is to be displayed is limited to the first background image HK1 and the second effect symbol EZb is displayed. The background images to be created may be the second background image HK2, the third background image HK3, and the fourth background image HK4.

Further, in the above embodiment, the first background change special table shown in FIG. 45 (A), the second background change special table shown in FIG. 46 (A), the third background change special table shown in FIG. 47 (A), and FIG. 48 ( In the 4th background change special table shown in A), the 5th background change special table shown in FIG. 49 (A), and the 6th background change special table shown in FIG. 50 (A), all the distribution rates (transition rates) are set. It was set to 25%. However, each of these fractions is just an example and can be changed as appropriate.

Further, in the above embodiment, the first background change normal table shown in FIG. 45 (B), the second background change normal table shown in FIG. 46 (B), the third background change normal table shown in FIG. 47 (B), and FIG. 48 ( In the fourth background change normal table shown in B), the fifth background change normal table shown in FIG. 49 (B), and the sixth background change normal table shown in FIG. 50 (B), each distribution rate (transition rate) is determined. It was set to 1 60% and 4 10%. However, each of these fractions is just an example and can be changed as appropriate. However, for example, in the first background change normal table shown in FIG. 45 (B), the probability (transition rate) of being changed to the second background image HK2 may be set to 50% or more. This makes it easy to change from the first background image HK1 to the second background image HK2, while making it difficult to change the display mode by leaving the effect symbol EZ as the first effect symbol EZa.

Further, in the above embodiment, the background change condition is that the number of times of variation display (number of variations of effect) of the effect symbol EZ in the normal gaming state is 20 times or more, and the background image is used using the background change execution lottery table shown in FIG. 44. It shall be established only when it is decided to carry out the change of. However, the establishment of the background change condition is not limited to the above, and can be changed as appropriate. For example, it may be established only when the number of stops of the effect symbol EZ (the number of fluctuation stops) is 15 or more and after the SP reach is lost. Further, as described above, the background change condition does not have to be two conditions, for example, the number of fluctuation stops and after SP reach loss, and may be one of them or three or more conditions.

Further, in the above embodiment, the change (background change) of the background image (background mode) can be executed at the start of a certain variation effect when the variation effect (variation display of the special symbol) is executed a plurality of times. rice field. However, the timing at which the background image is changed is not limited to the start of the variable effect, but may be, for example, the end of the variable effect, and can be changed as appropriate. Therefore, for example, the background image (background aspect) can be changed at an arbitrary timing during the variation effect, and the background image (background aspect) can be changed a plurality of times during one variation effect. You may do so.

Further, in the above-mentioned form, it is configured as a gaming machine in which the transition to the high probability state is determined based on the type of the winning jackpot symbol, but it is based on the passage of a so-called V probability machine (a specific area (V area) in the big winning opening). It may be configured as a gaming machine) that is controlled to a high probability state. Further, in the above embodiment, once controlled to a high probability state, it is configured as a gaming machine (so-called probabilistic loop type gaming machine) in which control to the high probability state continues until the start of the next jackpot game, but it is a so-called ST machine (probability variation). It may be configured as a game machine that cuts the number of times of the game) or a fall machine (a game machine whose high probability state ends depending on the lottery result). Further, it may be configured as a so-called 1-type / 2-type mixer or a honey-type gaming machine. That is, the invention shown in the present specification can be suitably adopted for a gaming machine having various game characteristics regardless of the game characteristics of the gaming machine.

Further, as a special game, a small hit game (a special game in which the total opening time of the large winning opening is as short as a predetermined time (for example, 1.8 seconds) or less) may be performed. The state in which the small hit game is being executed is called the small hit game state.

Further, there may be a plurality of (for example, two) large winning openings (large winning devices). In this case, the first big winning opening, the first big winning opening sensor that can detect the game ball that won the first big winning opening, the second big winning opening, and the game that won the second big winning opening. It is a gaming machine equipped with a second large winning opening sensor capable of detecting a ball.

Further, in the above embodiment, four random numbers such as a jackpot random number are acquired as random numbers (determination information) acquired based on the winning of the first starting port 11 or the second starting port 12, but one random number. And based on the random number, it may be decided whether or not it is a big hit, the type of hit, the presence or absence of reach, and the type of fluctuation pattern. That is, the number of random numbers to be acquired based on the starting prize and what is to be determined for each random number can be arbitrarily set.

Further, in the above embodiment, the pachinko gaming machine is configured to be controlled to the jackpot gaming state (special gaming state) under the control condition that the special symbol indicating that the jackpot is won is stopped and displayed. On the other hand, it may be configured as a slot machine (rotary drum type gaming machine, pachislot gaming machine).

Further, the type of the slot machine may be any type. In the case of a so-called normal machine (A type slot machine) that increases the number of medals earned by winning a big bonus or a regular bonus, the state in which a bonus such as a big bonus or a regular bonus is executed corresponds to a special gaming state. In addition, if it is a so-called ART machine or AT machine that increases the number of medals won during a special game period such as ART (assist replay time) or AT (assist time) that can frequently win small roles, the state during ART or AT. Corresponds to the special gaming state. In addition, in the normal machine, the control conditions for the special game state are a combination of symbols that triggers the transition to the big bonus and regular bonus on the activated winning line after winning the big bonus and regular bonus. It is derived and displayed as the display result of the reel. Further, in the ART machine and the AT machine, the control condition to the special game state is, for example, after winning the execution lottery of the ART or AT, the specified number of games is exhausted, and the activation timing of the ART or AT is reached. be.
