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

  The number of such special figure reservations is displayed on the special figure reservation display 83. More specifically, each of the special figure reservation indicators 83 includes, for example, four LEDs, and displays the number of special figure reservations by lighting the LEDs for the number of special figure reservations.

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

  More specifically, the ordinary symbol display 82 is composed of, for example, two LEDs (see FIG. 5), and displays an ordinary symbol corresponding to the result of the ordinary symbol lottery according to the lighting mode. For example, when the lottery result is a winning, a normal winning symbol in which both LEDs are turned on is displayed, such as “（” (：: turned on, ●: turned off). When the lottery result is a loss, a normal loss pattern in which only the right LED is turned on, such as "● ○", is displayed. A mode in which all the LEDs are turned off may be adopted as a normal losing symbol. Note that the normal losing symbol is not a specific ordinary symbol. Before the normal symbol is stopped and displayed, the normal symbol is fluctuated for a predetermined fluctuating time. The fluctuating display is, for example, a mode in which both LEDs are alternately turned on. Note that the mode of the variable display may be anything such as all the LEDs blinking at the same time as long as each LED is not stopped (lighted display in a specific mode).

  In the present pachinko gaming machine PY1, when a game ball passes through the gate 13, the value of the ordinary symbol random number (winning random number) acquired for the passage is stored as a general figure holding in a general figure holding storage unit 106 described later. Once stored. There is an upper limit to the number of general drawing reservations that can be stored in the general drawing storage unit 106, and the upper limit in this embodiment is “4”.

  The general figure holding stored in the general figure holding storage unit 106 is exhausted when the variable display of the normal symbol based on the general figure holding becomes possible. The digestion of the ordinary symbol reservation means that the ordinary symbol random number (per random number) corresponding to the ordinary symbol reservation is determined, and the variable display of the ordinary symbol for indicating the determination result is executed. Therefore, in the present pachinko gaming machine PY1, when the variable display of the ordinary symbol based on the passage of the game ball to the gate 13 cannot be performed immediately after the passage, that is, during the execution of the variable display of the ordinary symbol and during the execution of the auxiliary game, the prize is won. Even if there is, the right of the ordinary symbol lottery for the passage can be reserved up to a predetermined number.

  Then, the number of such general drawing reservations is displayed on the general drawing holding display 84. More specifically, the general-purpose reservation indicator 84 is composed of, for example, four LEDs, and displays the number of general-purpose reservations by lighting the LEDs for the number of general-purpose reservations.

Therefore, a signal is input to each game control board 100 from each sensor, and a signal is output from each game control board 100 to each solenoid. Specifically, as sensors, a first starting port sensor 11a, a second starting port sensor 12a, a gate sensor 13a, a special winning opening sensor 14a, and a general winning opening sensor 10a are connected.

  The first starting port sensor 11a is provided in the first starting port 11 and detects a game ball that has won the first starting port 11. The second starting port sensor 12a is provided in the second starting port 12 and detects a game ball that has won the second starting port 12. The gate sensor 13a is provided in the gate 13 and detects a game ball that has passed through the gate 13. The special winning opening sensor 14a is provided in the special winning opening 14 and detects a game ball that has won the special winning opening 14. The general winning opening sensor 10a is provided in the general winning opening 10 and detects a game ball that has won the general winning opening 10.

  As the solenoids, an electric chu solenoid 12s and an AT solenoid 14s are connected. The electric tube solenoid 12s drives the electric tube opening / closing member 12k of the electric tube 12D. The AT solenoid 14s drives the AT opening and closing member 14k of the special winning device 14D.

  Further, the game control board 100 includes special figure display 81 (first special figure display 81a and second special figure display 81b), general figure display 82, special figure reservation display 83 (first special figure reservation display). The display 83a, the second special drawing reservation display 83b), and the general drawing reservation display 84 are connected. That is, the display control of these display devices 8 is performed by the game control microcomputer 101.

  The game control board 100 transmits various commands and signals to the payout control board 170 and receives signals from the payout control board 170 for payout monitoring. The payout control board 170 includes a card unit CU (which is installed adjacent to the pachinko gaming machine PY1 and allows a ball to be lent based on information such as an inserted prepaid card) and a prize ball payout device 73. In addition to being connected, the launch device 72 is connected via the launch control circuit 175. The firing device 72 includes a handle 72k (see FIG. 1).

  The payout control board 170 drives the prize ball motor 73m of the prize ball payout device 73 based on a signal from the game control microcomputer 101 and a signal from the card unit CU connected to the pachinko gaming machine PY1, and the prize ball. Or payout of rental balls. The game balls to be paid out are detected by the prize ball sensor 73a for counting, and a detection signal from 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 firing device 72, the touch switch 72a detects the contact with the handle 72k, and the firing volume 72b detects the rotation amount of the handle 72k. Then, the firing solenoid 72s is driven so that the game ball is fired with the strength corresponding to the magnitude of the detection signal of the firing volume 72b. In the pachinko gaming machine PY1, one game ball is fired in about 0.6 seconds.

  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 one-way communication connection that can only transmit signals 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 communication direction regulating means is interposed between the game control board 100 and the effect control board 120.

  As shown in FIG. 7, on the effect control board 120, an effect control one-chip microcomputer (hereinafter, “effect control microcomputer”) 121 for controlling the effect of the pachinko gaming machine PY1 according to a program is mounted. The effect control microcomputer 121 executes an effect ROM 123 storing a program for controlling the effect as the game progresses, an effect RAM 124 used as a work memory, and a program stored in the effect ROM 123. An effect CPU 122 and an effect I / O port unit 138 for inputting and outputting data and signals are included. The effect ROM 123 may be external.

  As shown in FIG. 7, the image control board 140 and the sub-drive board 162 (sub-drive circuit) are connected to the effect control board 120. The effect control microcomputer 121 of the effect control board 120 causes the image CPU 141 of the image control board 140 to perform display control of the image display device 50 based on the command received from the game control board 100. The effect control microcomputer 121 transmits a control signal via the image input circuit 147 of the image control board 140. Then, the image CPU 141 transmits a control signal to the image display device 50 via the image output circuit 148 of the image control board 140.

  The image RAM 143 of the image control board 140 is a memory for developing image data. In the image ROM 142 of the image control board 140, still image data and moving image data displayed on the image display device 50, specifically, characters, items, figures, characters, numbers and symbols (including decorative patterns) and background Image data such as an image is stored. The image CPU 141 of the image control board 140 reads image data from the image ROM 142 based on a command from the effect control microcomputer 121. Then, display control is executed based on the read image data.

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

  Although the image control board 140 controls the sound of the speaker 620, a sound control board may be provided separately from the image control board 140, and the sound control board controls the sound of the speaker 620. In this case, the sound 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. Further, a CPU may be mounted on the audio control board, and in that case, the CPU may execute the audio control. Further, in this case, a ROM may be mounted on the audio control board, and the ROM may store acoustic data.

  Also, as shown in FIG. 7, the effect control microcomputer 121 controls the lighting of the lamps such as the frame lamp 212 and the board lamp 54 via the sub-drive board 162 based on the command received from the game control board 100. . More specifically, the effect control microcomputer 121 creates light emission pattern data (data for determining lighting / extinguishing, light emission color, etc., also referred to as lamp data) that determines the light emission mode of each lamp, and emits light of each lamp according to the light emission pattern data. Control. Note that data stored in the effect ROM 123 of the effect control board 120 is used to create the light emission pattern data.

  Further, the effect control microcomputer 121 controls the drive of the board movable body 55k via the sub-drive board 162 based on the command received from the game control board 100. More specifically, the effect control microcomputer 121 creates operation pattern data (also referred to as drive data) for determining the operation mode of the board movable body 55k, and controls the drive of a motor for driving the board movable body 55k according to the operation pattern data. I do. The data stored in the effect ROM 123 of the effect control board 120 is used to create the operation pattern data.

  Note that a CPU may be mounted on the sub-drive board 162, and in that case, the CPU may control the lighting of the lamp and the drive of the panel movable body 55k. Further, in this case, a ROM may be mounted on the sub-drive board 162, and the ROM may store data relating to a light emission pattern or an operation pattern.

  The effect control board 120 is connected to an input unit detection sensor (effect button detection sensor) 40a and a select button detection sensor 42a. The input unit detection sensor 40a detects that the input unit 40k (see FIG. 1) has been pressed. When the input unit 40k is pressed, a detection signal is output from the input unit detection sensor 40a to the effect control board 120. The select button detection sensor 42a detects that the select button 42k (see FIG. 1) is pressed. When the select button 42k is pressed down, a detection signal is output from the select button detection sensor 42a to the effect control board 120.

  6 and 7 are functional block diagrams for describing an electrical configuration of the pachinko gaming machine PY1 to the last, and not only the substrates shown in FIGS. 6 and 7 are provided. Except for the game control board 100, any one of the plurality of boards shown in FIGS. 6 and 7 may be configured as one board, and one board shown in FIGS. 6 and 7 may be configured as a plurality of boards. good.

3. Description of Jackpots and the like In the pachinko gaming machine PY1 of the present embodiment, there is a “jackpot” and a “losing” as a result of the jackpot lottery (special symbol lottery). At the time of "big hit", "big hit symbol" is stopped and displayed on the special figure display 81. In the case of "losing", the "losing symbol" is stopped and displayed on the special map display 81. When a big hit is won, a "big hit game" in which the big winning opening 14 is opened in an opening pattern corresponding to the type of the special symbol stopped and displayed (big hit type) is executed. Jackpot games are also called special games.

  In the present embodiment, the jackpot game is a plurality of round games (unit open game), an opening (also referred to as OP) before the first round game is started, and an ending after the last round game is completed. (Also referred to as ED). Each round game is started by the end of the OP or the end of the previous round game, and is ended by the start of the next round game or the start of the ED. The closing time (interval time) of the special winning opening between round games is included in the open round game before the closing.

  There are several types of jackpots. The jackpot types are as shown in FIG. As shown in FIG. 8, in the present embodiment, there are roughly two types. Probable change jackpot and normal jackpot. The probability change jackpot is a jackpot for controlling the gaming state after the jackpot game to a high probability state described later. The normal jackpot is a jackpot for controlling the game state after the jackpot game to a normal probability state (low probability state) described later.

  More specifically, the winning jackpot 14 and the regular jackpot that can be won in the drawing of the special map 1 (the drawing of the first special symbol) open the special winning opening 14 from 1R to 8R for a maximum of 29.5 seconds per 1R. And, from 9R to 16R, the big win is opened for a maximum of 0.1 second per 1R. That is, although the total number of rounds of these jackpots is 16R, the actual number of rounds is 8R. The substantial number of rounds refers to the number of rounds in which game balls can win up to the maximum number of winnings per round (eight in this embodiment). From 9R to 16R in these jackpots, the opening time of the special winning opening 14 is extremely short, and a round in which a prize ball cannot be expected is formed. In addition, when the "special change big hit" is won by the drawing of the special figure 1, the "special figure 1_probable change pattern" is stopped and displayed on the first special figure display 81a, and when the "normal big hit" is won, “Special figure 1_normal symbol” is stopped and displayed on the first special figure display 81a.

  In addition, the winning jackpot and the normal jackpot that can be won in the drawing of the special map 2 (the drawing of the second special symbol) are the jackpots that open the special winning opening 14 from 1R to 16R for a maximum of 29.5 seconds per 1R. That is, these jackpots also have a substantial round number of 16R. In the case where the “special variable jackpot” is won by the lottery of the special figure 2, the “special figure 2_probable symbol” is stopped and displayed on the second special figure display 81b. “Special figure 2_normal symbol” is stopped and displayed on the special figure display 81b.

  Whichever jackpot is won, after the jackpot game, it is controlled to an electric support control state (high base state) described later. If the electric support control state is controlled in accordance with the high probability state, the state is continued until the next jackpot winning. On the other hand, when the control is performed in accordance with the normal probability state (low probability state), the number of times of power support (the number of time savings) is set to 100. The number of times of the electric support is the upper limit execution number of the variation display of the special symbol in the electric support control state.

  As shown in FIG. 8, the jackpot distribution rates in the lottery of Toku-zu 1 and the lottery of Toku-zu 2 are 65% for the probability variable jackpot and 35% for the normal jackpot. However, when a jackpot is won based on the drawing of Toku-zu 1, a jackpot game with a substantial number of rounds of eight is executed, whereas when a jackpot is won based on the drawing of Toku-zu 2, the actual 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 of 16 rounds is performed.

  Here, in the present pachinko gaming machine PY1, the lottery for determining whether or not a jackpot is performed is performed based on the “big hit random number”, and the lottery of the winning big hit type is performed based on the “hit random number”. As shown in FIG. 9A, the jackpot random number takes a value in a 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 in the first starting port 11 or the second starting port 12 include "reach random number" and "variation pattern random number" in addition to the jackpot random number and the hit type random number.

  The reach random number is a random number that determines whether or not to generate a reach in an effect design variation effect that indicates the result of the jackpot determination if the result is unacceptable. The reach is a state in which the effect symbol EZ that is variably displayed among the plurality of effect symbols EZ is the remaining one, and depends on which symbol the variably displayed effect symbol EZ is stopped and displayed. This is a state (for example, “7 ↓ 7”) that is a combination of the effect symbols EZ indicating the jackpot winning. The effect symbol EZ that is stopped and displayed in the reach state may be displayed so as to be slightly shaking in the display screen 50a, or may be displayed so as to be repeatedly enlarged and reduced. The reach random number takes a value in a range from 0 to 255.

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

4. Description of gaming state Next, a gaming state of the pachinko gaming machine PY1 of the present embodiment will be described. The special figure display 81 and the ordinary figure display 82 of the pachinko gaming machine PY1 have a probability variation function and a variation time reduction function, respectively. The state in which the probability variation function of the special map display 81 is operating is referred to as “high probability state”, and the state in which the probability variation function is not operating is referred to as “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 variation function of the special figure display 81 is activated, the probability that the display result of the variable display of the special symbol by the special figure display 81 (that is, the stop symbol) becomes a big hit symbol is lower than when the special figure display 81 is not activated. Will be higher.

  A state in which the fluctuation time reducing function of the special map display 81 is operating is referred to as a “time reduction state”, and a state in which the function is not operating is referred to as a “non-time reduction state”. In the time reduction state, the fluctuation time of the special symbol (the time from the start of the fluctuation display to the time of derivation display of the display result) is shorter than in the non-time reduction state. That is, a variation pattern is determined using a variation pattern table determined so that a variation pattern with a short variation time is selected more frequently than in a non-time saving state (see FIG. 11). That is, when the fluctuation time reducing function of the special figure display 81 is activated, a shorter fluctuation time is more likely to be selected as the fluctuation time of the variable display of the special symbol than when it is not activated. As a result, in the time-saving state, the pace of digestion of the special figure reservation is accelerated, and an effective prize (a prize that can be stored as the special figure reservation) to the starting port is likely to occur. Therefore, it is possible to aim for a jackpot with a smooth progress of the game.

  The probability variation function and the variation time reduction function of the special map display 81 may operate simultaneously, or only one of them may operate. The probability variation function and the variation time reduction function of the ordinary figure display 82 are operated in synchronization with the variation time reduction function of the special figure display 81. That is, the probability variation function and the variation time reduction function of the general-purpose indicator 82 operate in the time reduction state and do not operate in the non-time reduction state. Therefore, in the time reduction state, the winning probability in the ordinary symbol lottery is higher than in the non-time reduction state. That is, the hit determination (judgment of the normal symbol) is performed using the normal symbol hit determination table in which the value of the normal symbol random number (hit random number) determined to be a hit is larger than the normal symbol hit determination table used in the non-time saving state ( (See FIG. 10C). In other words, when the probability changing function of the ordinary symbol display 82 is activated, the probability that the display result of the variable display of the ordinary symbol by the ordinary symbol display 82 becomes the ordinary hit symbol is higher than when the probability variation function is not activated. .

  In addition, in the time reduction state, the fluctuation time of the symbol is usually shorter than in the non-time reduction state. In the present embodiment, the fluctuation time of the symbol is normally 7 seconds in the non-time reduction state, but is 1 second in the time reduction state (see FIG. 10D). 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 tube 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 tube 12D is operating.

  Under the condition that the probability variation function and the variation time shortening function of the general-purpose indicator 82 and the opening time extension function and the opening number increasing function of the electric tuner 12D are operating, compared to a case where these functions are not operating. As a result, the electric chew 12D is frequently opened, and the game ball frequently wins the second starting port 12. As a result, the base, which is the ratio of the number of award balls to the number of launch balls, increases. Therefore, a state in which these functions are operating is referred to as a “high base state”, and a state in which these functions are not operating is referred to as a “low base state”. In the high base state, a big hit can be aimed at without greatly reducing the number of game balls on hand. The high base state is a state in which so-called electric support control (control for supporting winning in the second starting port 12 by the electric tuner 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 require all of the above functions to operate. That is, the operation of one or more of the probability changing function of the general-purpose indicator 82, the variation time reducing function of the general-purpose indicator 82, the opening time extension function of the electric chew 12D, and the opening frequency increasing function of the electric chew 12D. Thus, it is only necessary that the electric chew 12D be more easily opened than when the function is not operating. Further, the high base state may be controlled independently without accompanying the time saving state.

  In the pachinko gaming machine PY1 of the present embodiment, the gaming state after the jackpot game by winning the certainty jackpot is a high probability state, a time saving state, and a high base state. This game state is particularly referred to as a “highly accurate high base state”. The high-accuracy-high-base state ends when a predetermined number of times (in this embodiment, 10,000 times) of a special symbol is variably displayed, or a jackpot is won and the jackpot game is executed. That is, in the present embodiment, the high probability and high base state substantially continues until the next jackpot winning. In addition, the termination condition of the high-accuracy high base state may be such that the jackpot is won and the jackpot game is executed.

  In addition, the game 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 game state is particularly referred to as a “low-probability high base state”. The low-probability-high base state ends when a predetermined number of times (100 times in this embodiment) of a special symbol is variably displayed, or when a jackpot is won and the jackpot game is executed.

  When the pachinko gaming machine PY1 is played for the first time, the gaming state after power-on is a normal probability state, a non-saving time state, and a low base state. This game 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”. In addition, a 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 in which the state is controlled to at least one of the high probability state and the high base state is referred to as a “bonus game state”.

  In the high base state such as the high certainty high base state and the low certainty high base state, it is advantageous to make the game ball enter the right game area 6R (see FIG. 4) by right-handing to advance the game. This is because the electric support 12 makes it easier for the electric tuner 12D to be opened than in the low base state, and makes it easier to win the second starting port 12 than to win the first starting port 11. . Therefore, while passing the game ball to the gate 13 which is a trigger of the normal symbol lottery, a right-handed shot is performed so that the game ball is awarded to the second starting port 12. As a result, a larger number of start winnings (winning at the starting opening) can be obtained than when the player hits left. Note that the pachinko gaming machine PY1 performs a right-handed game even during the big hit game.

  On the other hand, in the low base state, it is advantageous to allow the game ball to enter the left game area 6L (see FIG. 4) by left-handing to advantageously advance the game. Since the power support control is not executed, the power chute 12D is less likely to be opened than in 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 is. Therefore, a left hit is performed so that a game ball can be awarded to the first starting port 11. As a result, a larger number of start winnings can be obtained than when the player makes a right hit.

5. Operation of Game Control Microcomputer 101 [Main Control Main Processing] Next, the operation of the game control microcomputer 101 will be described with reference to FIGS. Note that counters, timers, flags, statuses, buffers, and the like that appear in the description of the operation 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 game control microcomputer 101 provided on the game control board 100 reads out and executes the main control main processing program shown in FIG. 13 from the game ROM 103. As shown in the figure, in the main control main process, first, an initial setting is performed (step S001). In the initial setting, for example, setting of a stack, setting of a constant, setting of an interrupt time, setting of the gaming CPU 102, setting of SIO, PIO, CTC (circuit for managing an interrupt time), various flags, statuses, counters, etc. And resetting. 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”. Note that the initial setting (S001) is executed only once after the power is turned on, and is not executed thereafter.

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

  When the normal symbol / special symbol main random number updating process (S003) ends, an interrupt is permitted (S004). While the interruption is permitted, the execution of the main-side timer interrupt processing (S005) is enabled. The main timer interrupt process (S005) is executed based on an interrupt pulse repeatedly input to the gaming CPU 102 at a period of, for example, 4 msec. That is, for example, it is executed at a period of 4 msec. From the end of the main timer interrupt process (S005) to the next start of the main timer interrupt process (S005), various counters for the normal symbol / special symbol main random number update process (S003) are used. The process of updating the value is repeatedly executed. When 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 Timer Interrupt Processing] Next, the main timer interrupt processing (S005) will be described. As shown in FIG. 14, in the main timer interrupt processing (S005), first, an output processing (S101) is executed. In the output process (S101), a command or the like set in an output buffer provided in the game RAM 104 of the game control board 100 in each process described below is output to the effect control board 120, the payout control board 170, and the like.

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

  The normal symbol / special symbol main random number updating process (S103) performed next is the same as the normal symbol / special symbol main random number updating 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. ), The period until the next main timer interrupt process (S005) starts).

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

  [Sensor Detection Processing] As shown in FIG. 15, in the sensor detection processing (S104), it is first determined whether or not a game ball has passed through the gate 13, that is, whether or not a game ball has been detected by the gate sensor 13a ( S201). If the game ball has passed through the gate 13 (YES in S201), a 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 process passes the gate passing process (S202) and proceeds to step S203.

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

  Subsequently, a 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 group shown in FIG. 9A is acquired), and the acquired random number values are stored in the second special figure holding storage unit 105b. It is stored in the storage area of the second special figure reservation storage unit 105b corresponding to the number of 2 reserved balls.

  Subsequently, in the sensor detection process (S104), it is determined whether or not a game ball has won the first starting port 11, that is, whether or not a game ball has been detected by the first starting port sensor 11a (S207). If no game ball has won the first opening 11 (NO in S207), the process is terminated. If a game ball has won the first opening 11 (YES in S207), the special figure 1 is reserved. Whether or not the number of balls (the number of first special figure reservations, specifically, the value of a counter for counting the number of first special figure reservations provided in the game RAM 104) has reached “4” (upper limit storage number) A determination is made (S208). If the number of reserved special figure 1 balls has reached “4” (YES in S208), the process is terminated, but if the number of reserved special figure 1 balls is less than “4” (NO in S208). ), “1” is added to the number of reserved special figure 1 balls (S209).

  Subsequently, a special figure 1 related random number acquisition process (S210) is performed, and this process ends. In the special figure 1 related random number acquisition processing (S210), similar to the special figure 2 related random number acquisition processing (S206), the jackpot random number counter value (label-TRND-A) and the hit type random number counter value (label-TRND-AS) , The reach random number counter value (label-TRND-RC) and the fluctuation pattern random number counter value (label-TRND-T1) are acquired (that is, the random number group shown in FIG. 9A is acquired), and It is stored in the storage area of the first special figure reservation storage unit 105a corresponding 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), the number of ordinary symbol holding balls (the number of ordinary symbol holding, specifically, a counter provided in the game RAM 104 for counting the number of ordinary symbol holdings) Is determined to be 4 or more (S301), and if the number of ordinary symbol reserved balls is 4 or more (YES in S301), the process is terminated. On the other hand, if the number of ordinary symbol reserved balls is not 4 or more (NO in S301), “1” is added to the number of ordinary symbol retained balls (S302), and ordinary symbol random number acquisition processing is performed (S303). In the ordinary symbol random number acquisition process (S303), an ordinary symbol random number counter value (label-TRND-H value, see FIG. 9B) is acquired, and the acquired random number value is stored in the ordinary symbol holding storage unit 106 of the game RAM 104. Out of the storage areas corresponding to the current number of ordinary symbol reserved balls.

  [Normal Operation Process] The game control microcomputer 101 performs a normal operation process (S105) following the sensor detection process (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 operating (S401). If the electric chew 12D is not in operation (NO in S401), subsequently, it is determined whether or not the normal symbol is being stopped and displayed (S402). If the normal symbol is not being stopped and displayed (NO in S402), then it is determined whether or not the normal symbol is being changed and displayed (S403). If the normal symbol is not being changed (NO in S403), then it is determined whether or not the number of reserved balls of the ordinary symbol is “0” (S404). If the number of reserved balls of the normal symbol is "0" (YES in S404), the process is terminated.

  If the number of reserved balls of the ordinary symbol is not “0” in step S404 (NO in S404), a hit determination process is performed (S405). In the hit determination process (S405), the normal symbol random number counter value (the value of the label -TRND-H) stored in the ordinary symbol holding storage unit 106 is read, and based on the normal symbol hit determination table shown in FIG. It is determined whether it is a hit. Then, a symbol determination process of setting the general symbol stop symbol data according to the result of the hit determination in a predetermined storage area of the gaming RAM 104 is performed (S406). That is, in the symbol determination process (S406), if "losing", data corresponding to "general symbol loss symbol" is set, and if "hit", data corresponding to "normal winning symbol" is set.

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

  Next, the game control microcomputer 101 decrements the number of ordinary design holding balls by one (S408). Then, the storage location (storage area) of each of the general figure holdings in the general figure holding storage unit 106 is shifted by one to the side read from the current position, and the storage corresponding to the fourth holding in the general figure holding unit 106 is performed. The area (the storage area farthest from the read side) is cleared (S409). In this way, the general drawing reservations are digested in the order in which they were reserved. After that, the game control microcomputer 101 starts the variation display of the ordinary symbol in the ordinary symbol variation pattern selected in step S407 (S410). Along with this, a normal symbol change start command is set to notify the effect control board 120 of the start of the normal symbol change.

  If the variation of the ordinary symbol is being displayed in step S403 (YES in S403), then it is determined whether or not the variation time of the ordinary symbol has elapsed (S411), and if not, the process ends. On the other hand, if the elapsed time has elapsed (YES in S411), the fluctuation display of the normal symbol is stopped with the display result (normal hit symbol or normal loss symbol) according to the determination result of the normal symbol random number (S412). Then, a normal symbol fluctuation stop command for notifying the effect control board 120 of the normal symbol fluctuation stop is set (S413), and a normal symbol stop time is set (S414), and this processing is ended.

  Also, if the stop of the ordinary symbol is being displayed in the above-described step S402 (YES in S402), subsequently, it is determined whether or not the stop time of the ordinary symbol set in step S414 has elapsed (S415). 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 data of the normal hit symbol (that is, if it is not a hit) (NO in S416)), the process ends. On the other hand, if it is data of a normal winning symbol (that is, if it is a winning (YES in S416)), an opening pattern of the electric chew 12D is set (S417). More specifically, if it is in the time saving state, an opening pattern during the time saving state (see the electric power 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, an opening pattern in the non-time saving state (see the electric chewing opening TBL1 in FIG. 12) is set as the opening pattern of the electric chew 12D. Then, the electric tuner 12D is operated according to the opening pattern set in step S417 (S418).

  Also, if it is determined in step S401 that the electric chew 12D is operating (YES in S401), then it is determined whether the operating time of the electric chew 12D has elapsed (S419). Finish the process. On the other hand, if the time has elapsed (YES in S419), the operation of the electric chew 12D is terminated (S420).

  [Special Operation Process] The game control microcomputer 101 performs a special operation process (S106) following the normal operation process (S105) (see FIG. 14). As shown in FIG. 18, in the special operation process (S106), the process relating to the special figure display 81 and the special winning device 14D is divided into four stages, and each of these stages includes “special operation status 1, 2, 3, 4”. Is assigned. When the “special operation status” is “1” (YES in S1301), the game control microcomputer 101 performs a special symbol standby process (S1302), and the “special operation status” is “2”. In this case (NO in S1301, YES in S1303), the special symbol change processing (S1304) is performed, and when the "special operation status" is "3" (NO in S1301, S1303, YES in S1305) When the "special operation status" is "4" (NO in all of S1301, S1303, and S1305), the special electric auditors processing (S1307) is performed. Note that the special operation status is “1” in the initial setting.

  [Special Symbol Standby Process] As shown in FIG. 19, in the special symbol standby process (S1302), first, it is determined whether or not the number of reserved balls of the second starting port 12 (that is, the number of reserved special ball 2) is "0". Is determined (S1401). If the number of reserved balls in special figure 2 is “0” (YES in S1401), that is, if there is no storage of the random number counter value group acquired due to winning in 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 the special figure 1) is “0” (S1407). If the number of reserved balls in the special figure 1 is also “0” (YES in S1407), that is, if there is no storage of the random number counter value group acquired due to winning in the first starting port 11, the customer It is determined whether the wait flag is ON (S1415). If it is ON (YES in S1415), this process is ended, if it is not ON (NO in S1415), a customer waiting command is set in the output buffer of the gaming RAM 104 (S1416), and the customer waiting flag is turned ON (S1416) (S1417), this process ends.

  If the number of reserved balls in the special figure 2 is not “0” in step S1401 (NO in S1401), that is, storage of the random number counter value group acquired due to the winning in the second starting port 12 (reservation information of the special figure 2) If there is one or more, a special figure 2 big hit determination process (S1402) and a special figure 2 variation pattern selection process (S1403) described later are performed. Thereafter, the game control microcomputer 101 decrements the special figure 2 reserved ball count by one (S1404). Then, the storage location (storage area) of the various counter values in the second special figure holding storage unit 105b is shifted by one to the side to be read from the current position, and the first storage unit in the second special figure holding storage unit 105b is shifted. Is cleared (S1405). Subsequently, the game control microcomputer 101 executes a special figure 2 change start process (S1406), and proceeds to step S1413. In the special figure 2 change start process (S1406), the special operation status is set to “2” and the change start command is set in the output buffer of the gaming RAM 104, and the change display of the second special symbol is started. The change start command (also called special figure 2 change start command) set in the special figure 2 change start processing (S1406) includes the special figure stop symbol data set in the special figure 2 big hit determination processing (S1402). Information and information on the fluctuation pattern set in the special pattern 2 fluctuation pattern selection processing (S1403) (information including information on the fluctuation time) are included.

  Also, when the special figure 2 reserved ball number is “0” but the special figure 1 reserved ball number is not “0” (YES in S1401 and NO in S1407), If there is one or more storage of the random number counter value group acquired as a result of winning in the one starting port 11 (reservation information of the special figure 1), a special figure 1 big hit determination process (S1408) described later and the special figure One variation pattern selection processing (S1409) is performed. Thereafter, the game control microcomputer 101 decrements the special figure 1 reserved ball count by one (S1410). Then, the storage location (storage area) of the 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 storage unit in the first special figure reservation storage unit 105a is shifted. Is cleared (S1411). In this way, the first special drawing reservation is digested in the order in which the reservations are retained. Subsequently, the game control microcomputer 101 executes a special figure 1 change start process (S1412), and proceeds to step S1413. In the special figure 1 change start process (S1412), the special operation status is set to "2", and the change start command is set in the output buffer of the game RAM 104 to start the change display of the first special symbol. Note that the change start command (also called special figure 1 change start command) set in the special figure 1 change start processing (S1412) includes the special figure stop symbol data set in the special figure 1 big hit determination processing (S1408). Information and information on the fluctuation pattern (information including fluctuation time information) set in the special figure 1 fluctuation pattern selection process (S1409) are included.

  In step S1413, it is determined whether the customer waiting flag is ON. If the flag is ON, the customer waiting flag is turned OFF (S1414), and the process ends. As described above, in the present embodiment, the special symbol change display based on the first special figure reservation is performed only when the second special figure reservation is “0” (YES in S1401). That is, the second special map reservation is consumed prior to the first special figure reservation.

  [Special figure 2 big hit determination processing (special figure 1 big hit determination processing)] The processing flow of the special figure 2 big hit determination processing (S1402) and the special figure 1 big hit determination processing (S1408) is based on FIG. Will be described together. As shown in FIG. 20, in the special figure 2 big hit determination processing (S1402) or the special figure 1 big hit determination processing (S1408), first, a big hit random number counter value (label-TRND-A value) is read as a determination value (S1501). ). More specifically, in the special figure 2 big hit determination processing (S1402), the first storage area of the second special figure holding storage unit 105b of the gaming RAM 104 (that is, the storage area corresponding to the first second special figure holding). The stored jackpot random number counter value is read. In the special figure 1 big hit determination process (S1408), the first special figure reservation storage unit 105a of the gaming RAM 104 stores the first special figure reservation in the first storage area (that is, the storage area corresponding to the first special figure reservation first). Read the jackpot random number counter value.

  Next, a big hit determination table (FIG. 10A) is set (S1502). Next, it is determined whether or not the probable change flag is ON, that is, whether or not it is in the high probability state (S1503). If it is not the high probability state (NO in S1503), that is, if it is the normal probability state (non-high probability state), the table for the non-high probability state (big hit determination) in the jackpot determination table (FIG. 10A) It is determined whether the value is a big hit based on the value “1” to “210” (S1504). On the other hand, if the state is the high probability state (YES in S1503), the jackpot determination table (FIG. 10A) is used to determine whether the jackpot is determined based on the table for the high probability state (the jackpot determination value is “1” to “1660”). It is determined whether or not it is (S1505).

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

  [Special figure 2 fluctuation pattern selection processing (special figure 1 fluctuation pattern selection processing)] The processing flow of the special figure 2 fluctuation pattern selection processing (S1403) and the special figure 1 fluctuation pattern selection processing (S1409) is the same. This will be described collectively with reference to FIGS. 21 and 22. As shown in FIG. 21, in the special figure 2 fluctuation pattern selection processing (S1403) or the special figure 1 fluctuation pattern selection processing (S1409), first, it is determined whether or not the game state is the time reduction state (whether the time reduction flag is ON). Yes (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 determined whether or not the big hit flag is ON (S1602). If it is ON (YES in S1602), the fluctuation pattern random number counter value is referred with reference to the non-time saving state medium and large hits normal table (the portion corresponding to the non-time saving state and the big hit in the special figure fluctuation pattern determination table shown in FIG. 11). A variation pattern is selected based on (the value of the label-TRND-T1) (S1603). As shown in FIG. 11, if the fluctuation pattern is determined, the fluctuation time is also determined.

  In the fluctuating effect of the present pachinko gaming machine PY1, as described above, SP (super reach) may be executed in addition to Dohazure and normal reach. Therefore, as shown in FIG. 11, the fluctuation pattern is selected so that the de-losing, 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 having a longer fluctuation time after the reach than the normal reach. The distribution ratio of the table is set so that the SP reach is higher in winning expectation (expected degree for jackpot winning) than in normal reach. Here, the SP reach includes types of weak SP reach A, weak SP reach B, and strong SP reach. The distribution rates of various fluctuation patterns are set in the order of weak SP reach A → weak SP reach B → strong SP reach so as to increase the expectation of winning a jackpot.

  If the jackpot flag is not ON in step S1602 shown in FIG. 21, it is determined whether or not the reach random number counter value (label-TRND-RC value) is a reach-achieved random number value (S1604). As shown in FIG. 10B, the reach-achieved random number is “1” to “30” in the non-time saving state, and is “1” to “10” in the time saving state. In other words, reach in the loss is less likely to occur in the time reduction state than in the non-time reduction state. This is because, in the time reduction state, the speed of digesting the reservation of the special figure reservation is increased by selecting more the loss without reach having the short fluctuation time.

  If the reach random number counter value is a reach-achieved random value (YES in S1604), that is, in the case of a loss with reach, a loss with loss table during the non-hours saving state (a non-time-saving loss table in the special figure variation pattern determination table shown in FIG. 11). A variation pattern is selected based on the variation pattern random number counter value with reference to the time saving state and the part with the reach loss (S1605).

  On the other hand, when the reach random number counter value is not a reach random number value (NO in S1604), that is, in the case of a loss without reach, a loss-less loss table during the non-time saving state (in the special figure variation pattern determination table shown in FIG. 11). The change pattern is selected based on the change pattern random number counter value with reference to the non-time saving state and the portion corresponding to the loss without reach (S1606). At the time of the loss without the reach, a 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 variation pattern having a shorter variation time is selected as compared with when the number of reserved balls of the special symbol is "0" to "2". (See FIG. 11).

  If it is determined in step S1601 that the gaming state is the time reduction state (YES in S1601), the special figure variation pattern determination table to be referred to is the table in the time reduction state (see FIG. 11) as shown in FIG. The processing (S1607 to S1611) is performed in the same flow as in steps S1602 to S1606 except that the part corresponding to the time saving state in the special figure variation pattern determination table) is set.

  That is, if it is a jackpot, a variation pattern is selected based on the variation pattern random number counter value with reference to the portion corresponding to the jackpot during the time saving state of FIG. 11 (S1608). If there is a losing with reach, a variation pattern is selected based on a variation pattern random number counter value with reference to the portion corresponding to the losing with reach in the time saving state of FIG. 11 (S1610). If there is no reach, a variation pattern is selected based on the variation pattern random number counter value with reference to the portion corresponding to the reach-less loss during the time saving state of FIG. 11 (S1611).

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

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

  [Special symbol variation processing] As shown in FIG. 23, in the special symbol variation processing (S1304), first, the special symbol variation time (variation time determined according to the variation pattern selected in step S1403 or S1409, FIG. 11). It is determined whether or not has elapsed (S1801). If it has not elapsed (NO in S1801), this process is immediately terminated. Thus, the variable display of the special symbol is continued.

  On the other hand, if the fluctuation time has elapsed (YES in S1801), a 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 a symbol (big hit symbol or a lost symbol) according to the set special symbol stop symbol data (S1804), the process ends.

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

  Next, it is determined whether the big hit flag is ON (S1903). If the big hit flag is ON (YES in S1903), an opening pattern (see FIG. 8 for details) according to the type of the big hit that has been won is set (S1904). At this time, the value of the round counter that counts the number of unit open games (round games) executed during the jackpot game is set to the number of rounds according to the type of the jackpot that has been won. The setting of the release pattern (the set of data according to the release pattern) may be performed for each round.

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

  If the big hit flag is not ON in step S1903 (NO in S1903), the special operation status is set to "1" (S1909) because the big hit game is not started, and the process ends.

  [Gaming State Management Processing] As shown in FIG. 25, in the gaming state management processing (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 times the special symbol executed during the high probability state is decremented by 1 (S2002), and whether or not the value of the probability variation counter is "0" A determination is made (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 in step S2001 or S2003 is NO, the process immediately proceeds to step S2005.

  In step S2005, it is determined whether the time saving flag is ON. If it is ON (YES in S2005), the value of the time reduction counter for counting the number of times the special symbol executed during the time reduction state is decremented by 1 (S2006), and it is determined whether or not the value of the time reduction counter is "0". Yes (S2007). If "0" (YES in S2007), the time reduction 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 designation 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. This is set in the output buffer of the RAM 104, and this processing ends.

  [Special electric auditors processing (big hit game)] As shown in FIG. 26, in the special electric auditors processing (S1307), first, it is determined whether or not the big hit end flag is ON (S2201). The big hit end flag is a flag indicating that the opening of the big winning port 14 has been completely ended in the running big hit game.

  If the jackpot end flag is not ON (NO in S2201), it is determined whether or not the special winning opening 14 is being opened (S2202). If it is not during opening (NO in S2202), it has reached the time to open the special winning opening 14, that is, it has reached the time of opening start in the first round game after the opening time of the jackpot game has elapsed, or Then, it is determined whether or not the interval time (closing time) until the once-closed special winning opening 14 is reopened has reached the opening start time (S2203).

  If the decision result in the step S2203 is NO, the process is ended as it is. On the other hand, if the decision result in the step S2203 is YES, the special winning opening 14 is opened according to an opening pattern (see FIG. 8) according to the type of the jackpot (S2204).

  In a succeeding step S2205, a round designation command transmission determination process is performed. In the round designation command transmission determination processing (S2205), it is determined whether or not the opening of the special winning opening 14 in step S2204 is the first opening during one round game. The round designation command including the information on the number of rounds is set in the output buffer of the game 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 designation command is always set.

  In step S2202 of the special electric accessory processing (S1307), if the special winning opening 14 is being opened (YES in S2202), it is determined whether or not the closing condition of the special winning opening 14 is satisfied (S2206). In the present embodiment, the closing condition is that the number of winnings to the special winning opening 14 in the round game has reached a prescribed maximum winning number (8 in this embodiment), or the time for closing the special winning opening 14. (I.e., a predetermined opening time (see FIG. 8) has elapsed since the opening of the special winning opening 14). Then, if the closing condition of the special winning opening 14 is not satisfied (NO in S2206), the process ends.

  On the other hand, when the closing condition of the special winning opening 14 is satisfied (YES in S2206), the special 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 has not been completed (NO in S2208), this processing ends. On the other hand, when one round game is over (YES in S2208), the value of the round counter is decremented by one (S2209), and it is determined whether the value of the round counter is “0” (S2210). . If it is not "0" (NO in S2210), the process is terminated as it is to start the next round game.

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

  If the big hit end flag is ON in step S2201 (YES in S2201), it is determined whether the big hit ending time has elapsed since the last round has ended (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 big hit end flag is turned off (S2215), the big hit flag is turned off (S2216), and the special operation status is set to “1” (S2217). Thus, in the next main timer interrupt process (S005), the special symbol standby process (S1302) is executed again as the special operation process (see FIG. 18). Thereafter, a game state setting process (S2218) described later is performed, and the process ends.

  [Gaming State Setting Processing] As shown in FIG. 27, in the gaming state setting processing (S2218), first, the type of the big hit is the probability variable big hit (the stop symbol is special figure 1_big hit symbol 1 or special figure 2_big hit symbol 1, see FIG. 8). ) Is determined (S2301). If it is not a probability change jackpot (NO in S2301), the time reduction flag is turned on (S2306), and "100" is set in the time reduction counter (S2307), and the process proceeds to step S2308. As a result, the game state after the current big hit game becomes the normal probability state, the time saving state, and the high base state (that is, the low-probability high base state). The low-probability-high base state ends when one of the conditions of performing the variable display of the special symbol 100 times or winning the next big hit 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 reduction flag is turned ON (S2303). Then, "10000" is set in the probability change counter (S2304), and "10000" is set in the time reduction counter (S2305), and the process proceeds to step S2308. As a result, the gaming state after the current jackpot game becomes the high probability state, the time saving state, and the high base state (that is, the high-accuracy high base state). This high probability and high base state will continue until substantially the next jackpot is won. Until the value of the probability change counter and the value of the time reduction counter change from "10000" to "0", it is almost impossible to execute the change display of the special symbol. This is because it is not turned off until it is turned off. It is also possible to use only the probability change flag without providing the probability change counter and continue the high probability state until the next jackpot is won.

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

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

  As shown in FIG. 28A, a background image which is a background mode (first background mode) showing a daytime mountain scenery is referred to as a “first background image HK1”. Further, as shown in FIG. 28B, a background image which is a background mode (second background mode) showing the night mountain scenery is referred to as a “second background image HK2”. Further, as shown in FIG. 28C, a background image which is a background mode (third background mode) showing the scenery of a daytime city is referred to as a “third background image HK3”. Further, as shown in FIG. 28D, a background image that is a background mode (fourth background mode) showing the night city scenery is referred to as a “fourth background image HK4”. In addition, as shown in FIG. 28E, a background image which is a background mode (fifth background mode) showing the earth in space will be referred to as a “fifth background image HK5”. Further, as shown in FIG. 28 (F), a background image which is a background mode (sixth background mode) showing Saturn in space will be referred to as a “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.

  In the present embodiment, the effect symbols EZ displayed in the normal gaming state include three types of effect symbols having different display modes as shown in FIG. More specifically, "first directing design EZa" reminiscent of the protagonist character's childhood, "second directing design EZb" reminiscent of the protagonist character's high school age, and "third directing design EZb" recalling the pro character's professional age There are three types of effect design EZc ”.

  As shown in FIGS. 28 (A) and (B), as the first effect symbol EZa, the first effect symbol EZa indicating the childhood of the main character and the number “7”, and the child of a rival character rivaling the main character. There is a first effect design EZa indicating the age and the number "9", a first effect design EZa indicating the childhood of the sister character who is the sister of the main character, and the number "1", and the like. Here, as the first effect design EZa, a first effect design EZa indicating numbers from "1" to "9" is prepared in all, and the first effect design EZa is provided with a character reminiscent of the childhood of the main character. It is one effect design EZa. That is, in the display mode of the first effect symbol EZa (first display mode), a character reminiscent of the childhood of the main character is shown.

  As shown in FIGS. 28 (C) and (D), as the second effect design EZb, the second effect design EZb showing the high school period of the main character and the number “7”, and the rival character high school that is a rival of the main character. There is a second effect design EZb indicating the age and the number "9", a second effect design EZb indicating the high school age of the older sister character, the sister of the main character, and the number "1". Here, as the second effect design EZb, a second effect design EZb showing numbers from "1" to "9" is prepared in total, and the second effect design EZb is provided with a character reminiscent of the main character's high school days. It is a two-stage design EZb. That is, in the display mode of the second effect symbol EZb (second display mode), a character reminiscent of the hero character in high school is shown.

  As shown in FIGS. 28 (E) and (F), as the third production symbol EZc, a third production design symbol EZc indicating the pro era of the main character and the number “7”, and a rival character professional who is a rival of the main character. There is a third effect design EZc indicating the age and the number "9", a third effect design EZc indicating the adult age of the older sister character who is the main character's older sister and the number "1", and the like. Here, as the third effect design EZc, a third effect design EZc showing numbers from "1" to "9" is prepared in total, and each of the third effect design EZc is provided with a character reminiscent of the pro era of the hero character. There are three production symbols EZc. That is, in the display mode of the third effect symbol EZc (third display mode), the character is a character reminiscent of the pro era of the main character. The description of the effect symbols displayed in the high-accuracy high base state and the effect symbols displayed in the low-accuracy 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 is not displayed. Thus, the first background image HK1 and the second background image HK2 are the display conditions of the first effect symbol EZa, and can be said to be in the “first effect symbol group” reminiscent of the childhood of the main character. . In addition, 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. Is not displayed. Thus, the third background image HK3 and the fourth background image HK4 are the display conditions of the second effect symbol EZb, and can be said to be in the “second effect symbol group” reminiscent of the protagonist character's high school days. . The third effect symbol EZc is displayed only when the fifth background image HK5 or the sixth background image HK6 is displayed, and the first background image HK1, the second background image HK2, the third background image HK3, and the fourth background image HK4. Is not displayed. Thus, the fifth background image HK5 and the sixth background image HK6 are the display conditions of the third effect symbol EZc, and can be said to be in the “third effect symbol group” that reminds the professional era of the main character. .

  Here, in the present embodiment, six types of background images (a first background image HK1, a second background image HK2, a third background image HK3, a fourth background image HK4, and a fifth background image) are set based on the satisfaction of a predetermined background change condition. From the image HK5 and the sixth background image HK6), the current background image can be changed to another background image by lottery. This makes it difficult for the player to get tired of the background image. However, changing the background image (changing the background aspect) has the following problems.

  For example, when the first background image HK1 (see FIG. 28A) is displayed, 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) both during the display of the first background image HK1 and during the display of the second background image HK2. , The design of the effect will not be changed. Thereafter, it is assumed that the background change condition is satisfied when the current background image is the second background image HK2, and the change to the first background image HK1 is determined by lottery. Then, by changing from the second background image HK2 to the first background image HK1, the player immediately returns to the first background image HK1 from the viewpoint of the player. As a result, the player may have an impression as if the same background image appears frequently, which may lead to a decrease in the amusement of the effect.

  When the first background image HK1 is changed to the first background image HK1 via the second background image HK2, the effect design EZ remains the first effect design EZa, and during that time, the effect design EZ is not changed. Different. On the other hand, it is conceivable that six types of effect symbols EZ are provided corresponding to each of the six types of background images. However, in this case, the effect design EZ is always changed every time the background image is changed. As a result, there is a possibility that the player may have an impression that the effect symbols EZ are excessively changed. As described above, it is possible to prevent the effect of changing the design symbol EZ by changing the background image, and to prevent the effect of changing the effect symbol EZ from being excessively changed, thereby appropriately changing the effect design EZ. Needed to be improved.

  Therefore, in the present embodiment, in order to address the above-described problem, as shown in FIG. 28, the type of the effect symbol EZ is changed to three types smaller than the type of the background image (the first effect symbol group and the second effect symbol). Group and the third effect symbol group), and 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 (transition rate) of being changed to another background image in the effect symbol group is increased, and another effect symbol is changed. Reduce the probability of changing 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 set high (60% in the present embodiment). Has a low probability of being changed to the third background image HK3 or the fourth background image HK4 in the second effect symbol group and the fifth background image HK5 or the sixth background image HK6 in another third effect symbol group. In each case it is 10%). Thereby, since it is basically easy to change from the first background image HK1 to the second background image HK2, the effect symbol EZ is less likely to be changed without changing the first effect symbol EZa. As a result, even if the first background image HK1 is changed to the second background image HK2, the same variation display of the first effect design EZa can be shown to the player, and excessive change of the effect design EZ is prevented. It is possible to

  In addition, in this embodiment, exceptionally, if the background image immediately before being changed to the current background image is another background image in the same effect symbol group, the current background image is replaced with another background image. The image is not changed. 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 current background image 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 (another background image) in the same first effect symbol group. Image). Then, when changing from the second background image HK2, without changing to the first background image HK1, the third background image HK3 or the fourth background image HK4 in another second effect symbol group, or another third effect symbol is used. It will be changed to either the fifth background image HK5 or the sixth 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 having an impression of returning to the same background image immediately. That is, it is possible not to give an impression that the same background image frequently appears, and it is possible to enhance the amusement of the effect.

  And, in this embodiment, exceptionally, if the background image immediately before being changed to the current background image is another background image in the same effect symbol group, the effect of the background image is always changed to another effect symbol. Changed to the background image of the group. Therefore, in this case, the display mode of the effect symbol EZ is necessarily changed by changing the background image. That is, in the example described above, 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 (shift rate) of being changed to another background image in the same effect symbol group, it is possible to prevent the effect symbol EZ from being excessively changed. Then, exceptionally, 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 . Thereby, it is possible to prevent a situation where the display mode of the effect symbol EZ is not changed for a while. In this way, it is possible to achieve both the appropriate change of the display mode of the effect symbol EZ and the prevention of the frequent appearance of the background image of the same background mode.

  Here, in this embodiment, the background change condition for changing the background image in the normal gaming state will be described. The background change condition is such that when the number of times of the variable display of the effect symbol EZ in the normal gaming state (the number of variable effects) is 20 or more and the background image is changed using the background change execution lottery table shown in FIG. Only when it is determined, it is established. In other words, when the number of variable effects in the normal gaming state is less than 20, the background image is not changed. Even if the number of variable effects in the normal gaming state is 20 or more, if it is not determined to execute the background image change using the background change execution lottery table shown in FIG. 44, the background image may be changed. There is no. The variable effect number is reset to “0” times when the big hit game (big hit effect) is started.

  In the present embodiment, as shown in FIG. 28, the first background image HK1 and the second background image HK2 can be said to be the same type of background image in the sense that both show a mountain view. Images can be called different types of background images. Further, the third background image HK3 and the fourth background image HK4 can 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 called different types of background images. . Further, the fifth background image HK5 and the sixth background image HK6 can be said to be the same type of background image in the sense that they both show the view of the universe, and the other background images can be called different types of background images. . Therefore, in the present embodiment, basically, the probability (transition rate) of changing from the current background image to the same type of background image is increased. In addition, when background images before the current background image are 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, the background change can be shown in a well-balanced manner by not displaying the same type of background image three times in succession while showing the same type of background image to the player.

  Next, an effect example in the case of changing the background image will be described with reference to FIG. First, as shown in FIG. 29A, the first background image HK1 is displayed on the display screen 50a, and the first effect symbol EZa is variably displayed. As a precondition, the second background image HK2 that is the same first effect symbol group is not displayed as a background image before the first background image HK1 shown in FIG. 29A is displayed. Then, as shown in FIG. 29B, in a state where the first background image HK1 is displayed, the first effect symbol EZa is stopped and displayed in, for example, the losing mode “179”.

  Thereafter, it is assumed that the background change condition has been satisfied at the time when the variable 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 that is the same first effect symbol group is increased (see FIG. 45 (B) )reference). Therefore, it is determined that the image is changed to the second background image HK2. 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 is not changed. become.

  As a result, as shown in FIG. 29C, the display is switched to the display of the second background image HK2 on the display screen 50a, 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, by not changing the display aspect of the effect symbol EZ, it is possible to prevent the effect symbol EZ from being excessively changed. Then, as shown in FIG. 29 (D), in a state where the second background image HK2 is displayed, the first effect symbol EZa is stopped and displayed in, for example, the losing mode “199”.

  Thereafter, it is assumed that the background change condition has been satisfied at the time when the variable 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 image group) in the same effect symbol group (first effect symbol group). Image HK1). Therefore, from among the background images (the third background image HK3, the fourth background image HK4, the fifth background image HK5, and the sixth background image HK6) other than the current second background image HK2 and the immediately preceding first background image HK1. The background image to be changed is determined by lottery (see FIG. 46A). Therefore, at this time, it is determined that the image is changed to the fourth background image HK4. In this case, since the second effect symbol EZb is to be displayed during the display of the fourth background image HK4 (see FIG. 46A), the first effect symbol EZa is switched to the second effect symbol EZb. Will be changed.

  As a result, as shown in FIG. 29 (E), the display is switched to the display of the fourth background image HK4 on the display screen 50a, and the variable display of the second effect symbol EZb is started. In this manner, 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 is always changed by the current background change, and the effect pattern EZ is changed. It is possible to prevent a situation where the display mode is not changed for a while. Then, as shown in FIG. 29F, in a state where the fourth background image HK4 is displayed, the second effect symbol EZb is stopped and displayed in, for example, the losing mode “971”.

  Thereafter, it is assumed that the background change condition has been satisfied at the time when the variable effect is newly started. In this case, the change of the background image is determined by lottery so as to increase the probability (shift rate) of being changed to the third background image HK3 that is the same second effect symbol group (see FIG. 48 (B )reference). Therefore, it is determined that the image is changed to the third background image HK3. In this case, since the second effect symbol EZb is to be displayed during the display of the third background image HK3 (see FIG. 48B), the display mode of the effect symbol EZ is not changed. become.

  As a result, as shown in FIG. 29 (G), the display is switched to the display of the third background image HK3 on the display screen 50a, 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, by not changing the display aspect of the effect symbol EZ, it is possible to prevent the effect symbol EZ from being excessively changed. Then, as shown in FIG. 29 (H), in a state where the third background image HK3 is displayed, the second effect symbol EZb is stopped and displayed in, for example, the loss mode “917”.

  Thereafter, it is assumed that the background change condition has been satisfied at the time when the variable 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 the other background image (fourth background image) in the same effect symbol group (second effect symbol group). Image HK4). Therefore, from among the background images (the first background image HK1, the second background image HK2, the fifth background image HK5, and the sixth background image HK6) other than the current third background image HK3 and the immediately preceding fourth background image HK4. The background image to be changed is determined by lottery (see FIG. 47A). Therefore, at this time, it is determined that it is changed to the fifth background image HK5. In this case, since the third effect symbol EZc is to be displayed during the display of the fifth background image HK5 (see FIG. 47A), the second effect symbol EZb is changed to the third effect symbol EZc. Will be changed.

  As a result, as shown in FIG. 29 (I), the display is switched to the fifth background image HK5 on the display screen 50a, and the variable display of the third effect symbol EZc is started. In this manner, 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 is always changed by the current background change, and the effect pattern EZ is changed. It is possible to prevent a situation where the display mode is not changed for a while. Then, as shown in FIG. 29 (J), in a state where the fifth background image HK5 is displayed, the third effect symbol EZc is stopped and displayed in, for example, the loss mode “719”.

7. Operation of Effect Control Microcomputer 121 [Sub-Control Main Processing] Next, the operation of the effect control microcomputer 121 will be described with reference to FIGS. Note that counters, timers, flags, statuses, buffers, and the like that appear in the description of the operation 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. As shown in the figure, in the sub-control main process, first, a CPU initialization process is 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 performed.

  Subsequently, it is determined whether the power-off signal is ON and the contents of the effect RAM 124 are normal (S4002). If the result of this determination is NO, the effect RAM 124 is initialized (S4003), and the flow 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-off signal is not ON, or if the contents of the effect RAM 124 are not normal even if the power-OFF signal is ON (NO in S4002), the effect RAM 124 is initialized, but the power-off signal Is turned on, but if the contents of the effect RAM 124 are normally maintained (YES in S4002), the effect RAM 124 is not initialized. When the effect RAM 124 is initialized, the values of various flags, statuses, counters, and the like are reset. Steps S4001 to S4003 are executed only once after the power is turned on, and are not executed thereafter.

  In step S4004, the interrupt is prohibited. Next, a random number seed update process is executed (S4005). In the random number seed update process (S4005), the values of various effect determination random number counters are updated. Note that the effect determination random numbers include effect symbol determination random numbers for determining effect symbols EZ, variable effect pattern lottery random numbers for determining variable effect patterns, and announcement effect determination random numbers for determining various announcement effects. Etc. The method of updating the random numbers can be the same as the method of updating the random numbers performed by the game control board 100 described above. At the time of updating, instead of adding the random numbers one by one, two may be added. This is the same in the random number update processing performed by the game control board 100 described above.

  When the random number seed update process (S4005) ends, a 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 (variable effect, opening effect, round effect, ending effect, and the like accompanying the jackpot game) using the image display device 50 according to the command. Note that, with the execution of various effects by the image control board 140, the effect control board 120 outputs sound from the speaker 620 via the sound control board 161 or the board lamp 54 or the frame lamp via the sub-drive board 162. The light source 212 emits light and the panel movable body 55k is driven. The effect control microcomputer 121 subsequently permits an interrupt (S4007). Thereafter, steps S4004 to S4007 are looped. While interrupts are enabled, reception interrupt processing (S4008), 1 ms timer interrupt processing (S4009), and 10 ms timer interrupt processing (S4010) can be executed.

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

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

  Subsequently, a lamp data output process (S4202) is performed. In the lamp data output processing (S4202), the lamp data created in the other processing (S4305) in the later-described 10 ms timer interrupt processing (S4010) is sub-driven so that the board lamp 54 and the frame lamp 212 emit light at a timing suitable for the effect. Output to the substrate 162. That is, the panel lamp 54 and the frame lamp 212 emit light in a predetermined light emission mode according to the lamp data.

  Next, drive control processing is performed (S4203). In the drive control process (S4203), drive data (panel movable body drive data) is created or output so as to drive the panel movable body 55k at a timing suitable for the production such as SP reach or big hit production. That is, the panel movable body 55k is driven in a predetermined operation mode according to the drive data.

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

  [10 ms timer interrupt process] The 10 ms timer interrupt process (S4010) is executed each time an interrupt pulse having a period 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, a received command analysis process described later is performed (S4301).

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

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

  [Receive Command Analysis Process] As shown in FIG. 34, in the receive command analysis process (S4301), first, the effect control microcomputer 121 determines whether or not a game state designation command has been received from the game control board 100 (S4401). ), If it has been received, a mode status setting process is performed (S4402). In the mode status setting process (S4402), the received game state designation command is analyzed, and the mode status value is set based on the game state information included in the game state designation command. The value of the mode status is set to “1” in the normal game 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 current game state.

  Subsequently, the effect control microcomputer 121 determines whether or not a change start command (special figure 1 change start command or special figure 2 change start command) has been received from the game control board 100 (S4403). A variable effect start process 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). The variable effect ending process is performed (S4406). In the fluctuation effect ending process (S4406), the fluctuation stop command is analyzed, and a fluctuation effect end command for terminating the fluctuation 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 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 based on the analysis result, a pattern (contents) of the opening effect to be executed during the opening of the jackpot game is selected. Then, an opening effect start command for starting an 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 variable effect counter is for counting the number of times the variable effect has been executed since the background image was changed in the normal gaming state. Thus, 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 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 a 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 a round effect in 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 based on the analysis result, an ending effect pattern (content) to be executed during the ending of the jackpot game is selected. Then, an ending effect start command for starting an 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) based on a received command other than the above-described command (for example, a process for performing a customer-waiting effect based on the reception of a customer-waiting command, or a normal symbol variation). Based on the reception of the start command, a process for performing the ordinary figure fluctuation effect is performed, and the received command analysis process (S4301) is completed.

  [Variation Effect Start Process] As shown in FIG. 35, in the variation effect start process (S4404), first, the effect control microcomputer 121 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 big hit determination processing and the special figure 2 big hit determination processing (see FIG. 20), the special figure 1 fluctuation pattern selection processing, and the special figure 2 fluctuation pattern. It includes information on the fluctuation pattern set in the selection processing (see FIGS. 21 and 22), information specifying the current game state, and the like. It is assumed that the information acquired by the effect control microcomputer 121 can be appropriately used in the processing executed thereafter. Next, the effect control microcomputer 121 refers to the mode status value set at the present time (S4502).

  Subsequently, the effect control microcomputer 121 executes a variable effect pattern selection process (S4503). Once the fluctuating production pattern is determined, the fluctuating production time, the presence or absence of the reach production, the content of the reach production, the presence or absence of the SP reach, the content of the SP reach, the presence or absence of the production button production (SW production), the content of the production button production, the production development The details of the content of the fluctuating effect including the configuration and the like are determined.

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

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

  Subsequently, the effect control microcomputer 121 sets the variable effect start command for starting the selected variable effect pattern, the effect symbol EZ, and the announcement effect in the output buffer of the effect RAM 124 (S4507), and ends the process. . When the fluctuation effect start command set in step S4507 is transmitted to the image control board 140 by the command transmission process (S4006), the fluctuation effect synchronized with the fluctuation display of the special symbol is started on the display screen 50a. That is, as shown in FIG. 29, a change effect with a change in the background mode of the background image and a change in the display mode of the effect symbol EZ can be executed.

  [Background Image Selection Process] As shown in FIG. 36, in the background image selection process (S4504), first, the effect control microcomputer 121 determines whether or not the value of the mode status is "1" (S4601). If it is not "1" (NO in S4601), since it is in the high-accuracy time reduction state or the low-accuracy time reduction state, a background image different from each background image from the first background image HK1 to the sixth background image HK6 is displayed. become. Therefore, in this case, the process proceeds to step S4619, performs other background image selection processing, and ends this processing.

  On the other hand, if the value of the mode status is “1” (YES in S4601), the value of the variable effect counter is increased by “1” (S4602), and the flow proceeds to step S4603. Thus, every time the variable effect is started in the normal gaming state, the value of the variable effect counter is increased by one. In step S4603, it is determined whether the value of the variable effect counter is equal to or greater than “20”. If it is less than “20” (NO in S4603), it is determined that the background change condition has not been satisfied, and the present process ends. On the other hand, if the value of the variable effect counter is equal to or greater than “20” (YES in S4603), then, a 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. As a result, it is determined 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 has been determined. If the execution has not been determined (NO in S4605), this process ends. On the other hand, if the execution is determined (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.

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

  Therefore, when the background flag is “1” (YES in S4607), a first background change process for changing the current first background image HK1 to another background image is performed (S4608). Proceed to step S4618. If the background flag is “2” (NO in S4607, YES in S4609), a second background change process for changing the current second background image HK2 to another background image is executed ( (S4610), the process proceeds to step S4618. If the background flag is “3” (NO in S4607, NO in S4609, YES in S4611), a third background change process for changing the current third background image HK3 to another background image is performed. Execute (S4612), and proceed to step S4618. When the background flag is “4” (NO in S4607, NO in S4609, NO in S4611, YES in S4613), the fourth flag for changing the current fourth background image HK4 to another background image is used. A background change process is performed (S4614), and the process proceeds to step S4618. If the background flag is "5" (NO in S4607, NO in S4609, NO in S4611, NO in S4613, YES in S4615), the current fifth background image HK5 is changed to another background image. A fifth background change process is performed (S4616), and the process proceeds to step S4618. When the background flag is "5" (NO in S4607, NO in S4609, NO in S4611, NO in S4613, NO in S4615), the current sixth background image HK6 is changed to another background image. A sixth background change process is performed (S4617), and the process proceeds to step S4618. The value of the background flag is set to “1” in the initial setting.

  In step S4618, a background change command including background image information (information on the value of the background flag) 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 is set in the output buffer of the effect RAM 124, and the process ends. Thus, the background change command set in step S4618 is transmitted to the image control board 140, and the fluctuation effect start command (see FIG. 35) set in step S4507 is transmitted to the image control board 140 as described above. Thus, 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), a variable effect is executed with the changed effect symbol EZ.

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

  In step S5101, if the previous background flag is "2" (YES in S5101), the background image is displayed before the first background image HK1 although the background image is changed from the first background image HK1. This means that the image is the second background image HK2 that 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. 45A, and the process proceeds to step S5104. Specifically, in step S5102, a background change random number is obtained, and the background change random number obtained using the first background change special table shown in FIG. 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 display from returning to the second background image HK2 displayed immediately before the first background image HK1. Furthermore, it is always possible to 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, thereby preventing the first effect symbol EZa from being continuously displayed. It is.

  On the other hand, in step S5101, if the previous background flag is not “2” (NO in S5101), the background images displayed before the first background image HK1 are in the same first effect symbol group (see FIG. 28). It was not. Therefore, in this case, the process advances to step S5103 to determine the changed background image by lottery using the first normal background change table shown in FIG. 45B, and then advances to step S5104. More specifically, in step S5103, a background change random number is obtained, and the background change random number obtained using the first background change normal table shown in FIG. 45B is determined, whereby the second background image HK2 and the third background change random number are determined. 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 (shift 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 extremely high (60%). To). Thereby, it is possible to easily change the first background image HK1 to the second background image HK2. Then, the first effect symbol EZa is kept displayed even after switching to the second background image HK2, whereby it is possible to prevent the display mode of the effect symbol EZ from being immediately switched.

  In step S5104, the value of the background flag is set based on the lottery background image, and the flow advances 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 processing (S4608) is completed.

  [Second Background Changing Process] As shown in FIG. 39, in the second background changing process (S4610), first, the effect control microcomputer 121 determines whether or not the value of the previous background flag is "1" (step 46). S5201). If the background flag is “1” last time (YES in S5201), the background image displayed before the second background image HK2 is the same as the second background image HK2, although the background image is changed from the second background image HK2. This means that the first background image HK1 is one effect symbol group (see FIG. 28). Therefore, in this case, the process proceeds to step S5202, and the changed background image is determined by lot using the second background change special table shown in FIG. 46A, and the process proceeds to step S5204. More specifically, in step S5202, a background change random number is obtained, and the background change random number obtained using the second background change special table shown in FIG. 46A is determined, whereby the third background image HK3 and the fourth background change random number are determined. 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 display from returning to the first background image HK1 displayed immediately before the second background image HK2. Furthermore, it is always possible to 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, thereby preventing the first effect symbol EZa from being continuously displayed. It is.

  On the other hand, in step S5201, if the previous background flag is not “1” (NO in S5201), the background images displayed before the second background image HK2 are in the same first effect symbol group (see FIG. 28). It was not. 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. 46B, and the process proceeds to step S5204. Specifically, in step S5203, a background change random number is obtained, and the first background image HK1 and the third background change random number are determined by determining the background change random number obtained using the second background change normal table shown in FIG. 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. 46B, the probability (transition rate) that the first background image HK1, which is the first effect symbol group same as the second background image HK2, is determined by lottery is extremely high (60%). ) Is set. Thus, it is possible to easily change the second background image HK2 to the first background image HK1. Then, by making the first effect symbol EZa continue to be displayed even when the display is switched to the first background image HK1, it is possible to prevent the display mode of the effect symbol EZ from being immediately switched.

  In step S5204, the value of the background flag is set based on the drawn background image, and the flow advances to step S5205. Then, in step S5205, the value of the previous background flag is set to “2”, and the second background change processing (S4610) ends.

  [Third Background Change Processing] As shown in FIG. 40, in the third background change processing (S4612), first, the effect control microcomputer 121 determines whether or not the value of the previous background flag is "4" (step S412). S5301). If the previous background flag is “4” (YES in S5301), the background image displayed before the third background image HK3 is the same as the third background image HK3, although the background image is changed from the third background image HK3. This means that the fourth background image HK4, which is a two-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. 47A, and the process proceeds to step S5304. Specifically, in step S5302, a background change random number is acquired, and the first background image HK1 and the second background change random number are determined by determining the background change random number acquired using the third background change special table shown in FIG. 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 display from returning to the fourth background image HK4 displayed immediately before the third background image HK3. Furthermore, 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 to prevent the second effect symbol EZb from continuing to be displayed. It is.

  On the other hand, in step S5301, if the previous background flag is not "4" (NO in S5301), the background images displayed before the third background image HK3 are in the same second effect symbol group (see FIG. 28). It was not. 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. 47B, and the process proceeds to step S5304. Specifically, in step S5303, a background change random number is obtained, and the first background image HK1 and the second background change random number are determined by determining the background change random number obtained using the third background change normal table shown in FIG. 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 second effect symbol group same as the third background image HK3, is determined by lottery is extremely high (60%). ) Is set. Thus, it is possible to easily change the third background image HK3 to the fourth background image HK4. Then, even if the display is switched to the fourth background image HK4, by continuing to display the second effect symbol EZb, it is possible to prevent the display mode of the effect symbol EZ from being immediately switched.

  In step S5304, the value of the background flag is set based on the lottery background image, and the flow advances 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) ends.

  [Fourth Background Change Processing] As shown in FIG. 41, in the fourth background change processing (S4614), the effect control microcomputer 121 first determines whether or not the value of the previous background flag is "3" (step S4614). S5401). If the previous background flag is “3” (YES in S5401), the background image displayed before the fourth background image HK4 is the same as the first background image HK4, although the background image is changed from the fourth background image HK4. This means that the third background image HK3, which is a two-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 lot using the fourth special background change table shown in FIG. 48A, and the process proceeds to step S5404. More specifically, in step S5402, a background change random number is acquired, and the first background image HK1 and the second background change random number are determined by determining the background change random number acquired using the fourth special background change table shown in FIG. 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 display from returning to the third background image HK3 displayed immediately before the fourth background image HK4. Furthermore, 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 to prevent the second effect symbol EZb from continuing to be displayed. It is.

  On the other hand, in step S5401, if the previous background flag is not “3” (NO in S5401), the background images displayed before the fourth background image HK4 are in the same second effect symbol group (see FIG. 28). It was not. 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. 48B, and the process proceeds to step S5404. More specifically, in step S5403, a background change random number is acquired, and the background change random number acquired using the fourth background change normal table shown in FIG. 48B is determined, whereby the first background image HK1 and the second background change random number are determined. 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 (shift 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 extremely high (60%). To). Thus, it is possible to easily change the fourth background image HK4 to the third background image HK3. Then, even if the display is switched to the third background image HK3, the display state of the effect symbol EZ can be prevented from being switched immediately by keeping the second effect symbol EZb displayed.

  In step S5404, the value of the background flag is set based on the lottery background image, and the flow advances 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) ends.

  [Fifth Background Changing Process] As shown in FIG. 42, in the fifth background changing process (S4616), first, the effect control microcomputer 121 determines whether or not the value of the previous background flag is "6" (step S4616). S5501). If the previous background flag is "6" (YES in S5501), the background image displayed before the fifth background image HK5 is the same as the fifth background image HK5, although the background image is changed from the fifth background image HK5. This means that the sixth background image HK6, which is the three effect symbol groups (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. 49A, and the process proceeds to step S5504. Specifically, in step S5502, a background change random number is acquired, and the first background image HK1 and the second background image HK1 are determined by determining the background change random number acquired using the fifth special background change table shown in FIG. A 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 display from returning to the sixth background image HK6 displayed immediately before the fifth background image HK5. Furthermore, 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 to prevent the third effect symbol EZc from continuing to be displayed. It is.

  On the other hand, in step S5501, if the background flag was not “6” last time (NO in S5501), the background images displayed before the fifth background image HK5 belong to the same third effect symbol group (see FIG. 28). It was not. 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. 49B, and the process proceeds to step S5504. Specifically, in step S5503, a background change random number is obtained, and the first background image HK1 and the second background change random number are determined by determining the background change random number obtained using the fifth background change normal table shown in FIG. 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 (shift 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 extremely high (60%). ) Is set. Thereby, it is possible to easily change the fifth background image HK5 to the sixth background image HK6. Then, even if the display is switched to the sixth background image HK6, by keeping the third effect symbol EZc displayed, it is possible to prevent the display mode of the effect symbol EZ from being immediately switched.

  In step S5504, the value of the background flag is set based on the drawn background image, and the flow advances 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) ends.

  [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" (step S4617). S5601). If the background flag is “5” last time (YES in S5601), although the background image is changed from the sixth background image HK6, the background image displayed before the sixth background image HK6 is the same. This means that the fifth background image HK5, which is the three effect symbol groups (see FIG. 28). Therefore, in this case, the process proceeds to step S5602, the changed background image is determined by lottery using the sixth background change special table shown in FIG. 50A, and the process proceeds to step S5604. Specifically, in step S5602, a background change random number is obtained, and the first background image HK1 and the second background change random number are determined by determining the background change random number obtained using the sixth background change special table shown in FIG. A 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 display from returning to the fifth background image HK5 displayed immediately before the sixth background image HK6. Furthermore, 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 to prevent the third effect symbol EZc from continuing to be displayed. It is.

  On the other hand, in step S5601, if the previous background flag is not “6” (NO in S5601), the background images displayed before the sixth background image HK6 are in the same third effect symbol group (see FIG. 28). It was not. 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 illustrated in FIG. 50B, and the process proceeds to step S5604. Specifically, in step S5603, a background change random number is obtained, and the first background image HK1 and the second background change random number are determined by determining the background change random number obtained using the sixth background change normal table shown in FIG. 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 extremely high (60%). ) Is set. Thereby, it is possible to easily change the sixth background image HK6 to the fifth background image HK5. Then, even if the display is switched to the fifth background image HK5, by keeping the third effect symbol EZc displayed, it is possible to prevent the display mode of the effect symbol EZ from being immediately switched.

  In step S5604, the value of the background flag is set based on the lottery background image, and the flow advances 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) ends.

8. Effects 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 via the second background image HK2 (see FIG. 45A). That is, the first background image HK1 is easily 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 second background image HK2. In this way, it is possible to make it difficult to immediately return to the first background image HK1 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 amusement of the effect.

  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 to change it (see FIG. 47B). Therefore, it is possible to make it more difficult to immediately return to the first background image HK1 after the background image is changed from the first background image HK1.

  According to the pachinko gaming machine PY1 of the present embodiment, even when 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. Thereafter, when the second background image HK2 is changed to 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 Change to any of the three effect symbols EZc. That is, the display mode of the effect symbol EZ always changes. Thus, by changing the background mode of the background image, the display mode of the effect symbol EZ can be appropriately changed, and the effect symbol EZ can be hardly 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 changes from the first background image HK1 to the third background image HK3, the effect design EZ changes from the first effect design EZa to the second effect design 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 amusement of the effect.

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

  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. The image is changed to 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. 45A). 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 display of the first effect symbol EZa from being continued, to appropriately change the display mode of the effect symbol EZ, and to make the effect symbol EZ hard to get tired of.

  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). Thereafter, when the background image is changed from the third background image HK3, the background image is more easily 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. )), The effect symbol EZ is not changed and tends to remain as the second effect symbol EZb. Therefore, it is possible to prevent a situation where 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 effect is the same display mode. It is possible to show the symbol EZ moderately.

  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. The image is changed to 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. 48A). 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. Thus, 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 difficult to get tired of.

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

  In the above embodiment, as shown in FIG. 28, the background mode (first background mode) of the first background image HK1 is set to the background mode showing the scenery of the daytime mountain, and the background mode (second background mode) of the second background image HK2 is set. Mode) is set as the background mode indicating the night mountain scenery, the background mode (third background mode) of the third background image HK3 is set as the background mode indicating the daytime city view, and the background mode of the fourth background image HK4 is set. (Fourth background mode) is a background mode showing a night city view. However, the first background mode, the second background mode, the third background mode, and the fourth background mode are not limited to those described above, and show, for example, other landscapes, patterns, and colors (effects) such as the sea, river, and desert. It may be a background mode 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 indicates a character reminiscent of the childhood of the main character, and the display mode of the second effect symbol EZb ( The second display mode) indicates a character reminiscent of the protagonist character's high school days, and the display mode (third display mode) of the third staging pattern EZc indicates a character recalling the pro character's pro age. 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 in transformation, a character after transformation, and the like. It can be changed as appropriate.

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

  In the above embodiment, as shown in FIG. 28, each of the first effect symbol group, the second effect symbol group, and the third effect symbol group includes two background images. . 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 images included in the first effect symbol group are 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 this case, in any case where the first background image HK1 is changed to the third background image HK3, the display mode of the effect symbol EZ may not be changed (the first effect symbol EZa remains). . In this case, it is possible to suppress the effect design EZ from being changed more frequently with the change of the background image than in the first embodiment. The number of background images included in each effect symbol group may not be the same.

  Further, in the above embodiment, as shown in FIG. 28, there are six background modes of the background image changed in the normal gaming state. That is, the background images include the first background image HK1, the second background image HK2, the third background image HK3, the fourth background image HK4, the fifth background image HK5, and the sixth background image HK6. However, the background mode of the background image changed in the normal game state may be three, four, five, seven or more. Then, the background mode of the background image may be changed in other game states (high-accuracy time-saving state, low-accuracy time-saving state, high-accuracy non-time-saving state) instead of the normal gaming state.

  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 first background image HK1 is not changed (FIG. 45A). reference). However, even when the background image is changed after the first background image HK1 is changed to the second background image HK2, the first background image HK1 may be changed to the first background image HK1. In this case, it is preferable that the setting is made so that the second background image HK2 can be changed to the third background image HK3 more easily than the second background image HK2 is changed to the first background image HK1. More specifically, from the second background image HK, a background image other than the first background image HK1 and the second background image HK2 (a third background image HK3, a fourth background image HK4, a fifth background image HK5, and a sixth background image). It is preferable that the total probability of being changed to HK6) is 50% or more. Even in this case, it is possible to make it difficult for the first background image HK1 to return to the first background image HK1 immediately after passing through the second background image HK2, and to give the same background image (first background image HK1) to the player. Because it can be hard 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 to the third background image HK3. (See FIG. 45B). However, the probability (transition rate) of changing from the first background image HK1 to the third background image HK3 is the same as the probability (transition rate) of changing from the first background image HK1 to the second background image HK2, or the first. The probability that the background image HK1 is changed to the second background image HK2 may be higher. In this case, the first background image HK1 is more easily changed from the first background image HK3 to the third background image HK3, and the effect symbol EZ is more easily changed from the first effect symbol EZa to the second effect symbol EZb. It is possible. That is, the display mode of the effect symbol EZ can be more easily changed 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. (See FIG. 47B). However, the probability (transition rate) of changing from the third background image HK3 to the first background image HK1 is the same as the probability (transition rate) of changing from the third background image HK3 to the fourth background image HK4, or the third. The probability that the background image HK3 is changed to the fourth background image HK4 may be higher. 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 easier to change the effect symbol EZ from the second effect symbol EZb to the first effect symbol EZa. It is possible. That is, the display mode of the effect symbol EZ can be more easily changed by changing the background mode of the background image.

  In the above embodiment, as shown in FIG. 28, when the background image (background aspect) is changed, if 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 that is changed according to 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 of the stock image It may be a mode, a display mode of an image prompting operation of the operation means, a display mode of a warning image such as fraud, a cut-in preview image, a step-up preview image, or the like.

  In the above embodiment, the background images include the first background image HK1, the second background image HK2, the third background image HK3, the fourth background image HK4, the fifth background image HK5, and the sixth background image HK6. The embodiment in the case where the image is changed has been described. However, the background image in the embodiment is replaced with various effect 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 prompting the operation of the operation means. You may do it.

  In the above embodiment, as shown in FIG. 28, the background images on which the first effect symbol EZa is 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 changed are 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 displayed is only the first background image HK1, and the second effect symbol EZb is displayed. The background images to be performed may be the second background image HK2, the third background image HK3, and the fourth background image HK4.

  In the above embodiment, the first background change special table shown in FIG. 45A, the second background change special table shown in FIG. 46A, the third background change special table shown in FIG. In the fourth background change special table illustrated in FIG. 49A, the fifth background change special table illustrated in FIG. 49A, and the sixth background change special table illustrated in FIG. 25%. However, these distribution ratios are merely examples, and can be changed as appropriate.

  In the above embodiment, the first background change normal table shown in FIG. 45B, the second background change normal table shown in FIG. 46B, the third background change normal table shown in FIG. In the fourth background change normal table illustrated in FIG. 50B, the fifth background change normal table illustrated in FIG. 49B, and the sixth background change normal table illustrated in FIG. One 60% and four 10%. However, these distribution ratios are merely examples, and can be changed as appropriate. However, for example, in the first background change normal table shown in FIG. 45B, the probability (transition rate) of being changed to the second background image HK2 may be set to 50% or more. Thereby, while it is easy to change from the first background image HK1 to the second background image HK2, it is possible to make it difficult to change the display mode while the effect symbol EZ remains the first effect symbol EZa.

  Further, in the above embodiment, the background change condition is that the number of times of display of the effect symbol EZ in the normal gaming state (the number of times of the variable effect) is 20 or more, and the background image is displayed using the background change execution lottery table shown in FIG. Only when it is determined to execute the change of the above, it is established. However, establishment of the background change condition is not limited to the above, and can be changed as appropriate. For example, the present invention may be established only when the number of stop displays of the effect symbol EZ (the number of fluctuation stops) is 15 or more and after the SP reach loss. Further, as described above, the background change condition does not need to be the two conditions, for example, the number of fluctuation stops and after the SP reach loss, but may be one or three or more conditions.

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

  In the above-described embodiment, the gaming machine is configured to be shifted to the high-probability state based on the type of the winning jackpot symbol. However, a so-called V winning machine (based on passing through a specific area (V area) within the special winning opening). (A gaming machine controlled to a high probability state). Further, in the above-described embodiment, the gaming machine is configured as a gaming machine (a so-called probability-variable loop-type gaming machine) that, once controlled to the high-probability state, continues to be controlled to the high-probability state until the start of the next jackpot game. May be configured as a gaming machine with the number of times cut off) or a falling machine (a gaming machine whose high-probability state ends according to the lottery result). Moreover, you may comprise as what is called a 1 type 2 type | mold mixing machine, or a game machine of a fly type. That is, the invention described in the present specification can be suitably applied to gaming machines of 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 special 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 a small hit game state.

  In addition, there may be a plurality (for example, two) of large winning prize ports (large prize winning devices). In this case, the first large winning opening, the first large winning opening sensor capable of detecting a game ball winning the first large winning opening, the second large winning opening, and the game winning the second large winning opening The gaming machine is provided with a second special winning opening sensor capable of detecting a ball.

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

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

  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 obtained by winning a big bonus or a regular bonus, a state in which a bonus such as a big bonus or a regular bonus is executed corresponds to a special game state. Also, if the so-called ART machine or AT machine increases the medal in a special game period such as ART (Assist Replay Time) or AT (Assist Time), which can frequently win a small role, the state of the ART or AT Corresponds to the special game state. In the normal machine, the control conditions for the special gaming state are as follows: After winning the big bonus or regular bonus, the combination of symbols that trigger the transition to the big bonus or regular bonus on the activated pay line This is to be derived and displayed as a reel display result. In the case of the ART machine or the AT machine, the control condition for the special game state is, for example, that the ART or AT execution timing is reached by winning the execution lottery of the ART or the AT and exhausting the specified number of games. is there.
