  The lamp 111 is lit based on a control signal output from the main CPU 71. The speaker 112 outputs a sound such as BGM based on a control signal output from the main CPU 71.

  The graphic board 130 controls display of images performed by the upper image display panel 131 based on a control signal output from the main CPU 71. The graphic board 130 includes a VDP (Video Display Processor) that generates image data, a video RAM that stores image data generated by the VDP, and the like. Note that the image data used when generating image data by VDP is included in the game program read from the memory card 54 and stored in the RAM 73.

  The liquid crystal display device 134 displays an image based on a control signal output from the main CPU 71. The touch panel 137 detects a position touched by a player's finger or the like on the liquid crystal display device 134 and outputs a signal corresponding to the detected position to the main CPU 71.

  A stepping motor that rotates the reels 101, 102, and 103 is connected to the motor drive circuit 154. In addition, the motor drive circuit 154 includes a field programmable gate array (FPGA) and a driver. The FPGA is an electronic circuit such as a programmable LSI and functions as a control circuit for the stepping motor. The driver functions as an amplifier circuit for pulses input to the stepping motor.

  The index detection circuit 151 detects the position of the rotating reels 101, 102, and 103, and can detect the step-out of the reels 101, 102, and 103.

  The position change detection circuit 152 detects a change in the stop position of the reels 101, 102, 103 after the rotation of the reels 101, 102, 103 is stopped. For example, the position change detection circuit 152 changes the stop position so that it becomes a combination of symbols 501 related to winning by an external action such as fraud even though it is not actually a combination of symbols 501 related to winning. If it is, the change of the stop position of the reels 101, 102, 103 is detected. The position change detection circuit 152 detects changes in the stop positions of the reels 101, 102, and 103 by detecting fins (not shown) attached to the inner portions of the reels 101, 102, and 103 at predetermined intervals, for example. It is configured to be possible.

  The excitation method of the stepping motor is not particularly limited, and a 1-2 phase excitation method or a two phase excitation method can be adopted. Further, a DC motor may be employed instead of the stepping motor. When a DC motor is employed, a deviation counter, a D / A converter, and a servo amplifier are sequentially connected to the main body PCB 110, and the DC motor is connected to the servo amplifier. The rotational position of the DC motor is detected by a rotary encoder, and the current rotational position of the DC motor is supplied as data from the rotary encoder to the deviation counter.

  The backlight control circuit 153 is connected to supply driving power to the backlight device individually. The backlight control circuit 153 can change and control the amount of light when the illumination light is emitted in response to a command from the main CPU 71. Further, the five backlight devices provided on the inner peripheral surfaces of the reels 101, 102, and 103 individually illuminate the nine symbols 501 stopped in the display window 150 via the backlight control circuit 153. Can be emitted.

(Symbol combination table: for regular games)
Next, the symbol combination table for the base game will be described with reference to FIG.

  The symbol combination table for the base game defines a payout for the type and number of symbols (symbol combinations) rearranged on the PAY LINE in the base game. In the slot machine 1, the rotary scrolling of the reels 101, 102, 103 is stopped, and the combination of three symbols displayed (rearranged) on the PAY LINE matches the symbol combination defined by the symbol combination table. In this case, a prize is established. Then, according to the winning, a privilege such as a payout is given to the player. Note that if the symbol combination displayed (rearranged) on the PAY LINE does not match any of the symbol combinations defined by the symbol combination table, the winning is not established (so-called loss).

  Specifically, for “RED7”, “BLUE7”, “3BAR”, “2BAR”, and “1BAR” symbols, when three symbols are displayed on the PAY LINE, a winning is established. . A winning combination is also established as “ANY7” for a combination of symbols in which “RED7” and “BLUE7” are mixed. A winning combination is also established as “ANY BAR” for a combination of symbols in which “3BAR”, “2BAR”, and “1BAR” are mixed. Further, the “WILD” symbol substitutes for each type of symbol “RED7”, “BLUE7”, “3BAR”, “2BAR”, and “1BAR”. FIG. 9 shows the payout amount when betting 50 credits. Accordingly, when 50 credits are bet and a winning of “RED7” is established, a 2000 credit payout is awarded. In addition, when 100 credits are bet and a winning of “RED7” is established, a payout of 4000 credits is awarded.

  Further, the “COIN” symbol is a scatter symbol, and is a target of winning determination only by being rearranged in the display window 150 irrespective of the PAY LINE. Specifically, if one “COIN” symbol is rearranged among the nine symbols rearranged in the display window 150, “10” credits are awarded (when 50 credits are betted). . Further, if two “COIN” symbols are rearranged among the nine symbols rearranged in the display window 150, “20” credits are awarded (when 50 credits are betted). Also, if three “COIN” symbols are rearranged among the nine symbols rearranged in the display window 150, “50” credits are awarded (when 50 credits are betted).

(Symbol combination table: for free games)
Next, a symbol combination table for free games will be described with reference to FIG.

  The symbol combination table for free games, like the symbol combination table for normal games, prescribes the payout for the types and number of symbols (symbol combinations) rearranged on the PAY LINE in the free game.

  The symbol combination table for the free game is different from the symbol combination table for the normal game in that the “COIN” symbol is treated as the “F_COIN” symbol and the payout mode is different. This “F_COIN” symbol is a scatter symbol, and is only a rearrangement in the display window 150 regardless of the PAY LINE. That is, if the “F_COIN” symbol is rearranged among the nine symbols rearranged in the display window 150, a free game payout based on “special payout” is awarded. The “special payout”, which will be described in detail later, is a payout amount that is awarded together with five free games when a win including a “WILD” symbol is established in a normal game (predetermined condition).

  For example, in the normal game, when the winning of “BLUE7” including the “WILD” symbol is established, the payout amount to be given together with the five free games is 1000 credits (when 50 credits are bet). Accordingly, a free game payout based on 1000 credits as a “special payout” is awarded. Similarly, in the normal game, when a “3BAR” winning including the “WILD” symbol is established, the payout amount to be awarded together with the free game for five times is 500 credits (when 50 credits are bet). . Accordingly, a free game payout based on 500 credits as a “special payout” is awarded.

(Normal game symbol lottery table)
Next, the base game symbol lottery table will be described with reference to FIG. In the present embodiment, the base game symbol lottery table is referred to in the base game symbol lottery process for determining symbols to be rearranged in the middle stage of the display window 150 (on the PAY LINE) in the main control process (base game) described later. The reels 101, 102, and 103 are lottery tables in which values of rearrangement probabilities (WEIGHT) corresponding to 22 symbols are respectively defined.

  In the slot machine 1 of the present embodiment, the base game symbol lottery table shown in FIG. 11 is stored in the RAM 73. In the base game symbol lottery table, 22 symbols corresponding to the respective code numbers “0” to “21” are set with rearrangement probability (WEIGHT) values. For example, in the base game symbol lottery table shown in FIG. 11, “3BAR” corresponding to the code number “0” of the first reel 101 is re-established in the middle of the display window 150 (on the PAY LINE) with a probability of 5/98. Be placed. Further, “3BAR” corresponding to the code number “4” of the second reel 102 is rearranged in the middle stage of the display window 150 (on the PAY LINE) with a probability of 5/96. Further, “WILD” corresponding to the code number “4” of the third reel 103 is rearranged in the middle stage of the display window 150 (on the PAY LINE) with a probability of 5/154.

(Free game symbol lottery table)
Next, the free game symbol lottery table will be described with reference to FIG. In the present embodiment, the free game symbol lottery table is referred to in the free game symbol lottery process for determining symbols to be rearranged in the middle stage of the display window 150 (on the PAY LINE) in the free game process described later. , 102 and 103 are lottery tables in which values of rearrangement probabilities (WEIGHT) corresponding to 22 symbols are respectively defined.

  In the slot machine 1 of the present embodiment, the free game symbol lottery table shown in FIG. 12 is stored in the RAM 73. In the free game symbol lottery table, 22 symbols corresponding to the respective code numbers “0” to “21” are set with values of the probability of rearrangement (WEIGHT). For example, in the free game symbol lottery table shown in FIG. 12, “3BAR” corresponding to the code number “0” of the first reel 101 is re-established in the middle of the display window 150 (on the PAY LINE) with a probability of 5/98. Be placed. Further, “F_COIN” corresponding to the code number “12” of the second reel 102 is rearranged in the middle stage of the display window 150 (on the PAY LINE) with a probability of 7/96. Further, “WILD” corresponding to the code number “4” of the third reel 103 is rearranged in the middle stage of the display window 150 (on the PAY LINE) with a probability of 5/154.

(Magnification table)
Next, the magnification table will be described with reference to FIG. In the present embodiment, the magnification table is a lottery table that is referred to in a magnification determination lottery process of a free game process to be described later.

  In the magnification table of the present embodiment, a lottery probability (WEIGHT) is associated with magnifications 1 to 10 corresponding to eight ID numbers “0” to “7”. Specifically, “10/40” is associated as the lottery probability with the magnification “1 ×” corresponding to the ID number “0”. Further, “8/40” is associated with the magnification “1.5 times” corresponding to the ID number “1” as the lottery probability. Further, “7/40” is associated with the magnification “2 ×” corresponding to the ID number “2” as the lottery probability. Further, the magnification “2.5 times” corresponding to the ID number “3” is associated with “5/40” as the lottery probability. Further, the magnification “3 times” corresponding to the ID number “4” is associated with “4/40” as the lottery probability. Further, the magnification “4 times” corresponding to the ID number “5” is associated with “3/40” as the lottery probability. Further, the magnification “5 times” corresponding to the ID number “6” is associated with “2/40” as the lottery probability. In addition, the magnification “10 times” corresponding to the ID number “7” is associated with “1/40” as the lottery probability.

(Display screen)
Next, a mode displayed on the upper image display panel 131 in the base game or the free game will be described.

  As shown in FIG. 17, the game title is displayed on the upper image display panel 131 together with the gold bullion motif. In addition, below the upper image display panel 131, a payout table (see FIGS. 9 and 10) for the base game or the free game is displayed. Also, on the right hand side of the upper image display panel 131, a symbol of a “WILD” symbol (BONUS WILD), which is a symbol serving as a game catch phrase and a trigger condition for a free game, is displayed.

  As shown in FIG. 18, in the middle of the upper image display panel 131, the payout amount awarded in the free game is displayed. Further, above the upper image display panel 131, the total value of the payouts obtained during the free game is sequentially added and displayed on the bonus win meter. In addition, a stock counter 132 is displayed below the right hand side of the upper image display panel 131, and a stock counter value to be described later is displayed. For example, as shown in FIG. 18, when the value of the stock counter is “1”, it is displayed as “GOLD BONUS × 1”.

[Program contents]
Next, a program executed by the slot machine 1 will be described with reference to FIGS.

(Main control processing: normal game)
First, the main control process will be described with reference to FIG. In the main control process, a slot game in the normal game is executed.

  First, when power is turned on to the slot machine 1, the main CPU 71 reads out the authenticated game program and game system program from the memory card 54 via the gaming board 50, and writes them into the RAM 73 (S11).

  Next, in order to start the slot game in the normal game, the main CPU 71 performs an initialization process at the end of one game (S12). For example, unnecessary data for each slot game is cleared in the work area of the RAM 73, such as the number of bets and symbols determined by lottery.

  Next, the main CPU 71 performs a bet / start check process described later (S13). In this process, the input of the 50-BET switch 34S, 100-BET switch 35S, 150-BET switch 36S, 200-BET switch 37S, 250-BET switch 38S, spin switch 46S, etc. is checked.

  Next, the main CPU 71 conducts a normal game symbol lottery process (S14). In the base game symbol lottery process, the display window 150 is displayed for the first reel 101, the second reel 102, and the third reel 103 based on the probability (WEIGHT) defined in the base game symbol lottery table (see FIG. 11). Three symbols to be stopped to be rearranged in the middle stage (on the PAY LINE) are determined by lottery.

  For example, when the code number “2” is selected for the first reel 101 with the lottery probability 6/98, “RED7” corresponding to the code number “2” of the first reel 101 is displayed in the middle of the display window 150 ( The symbols to be stopped are determined to be rearranged on the PAY LINE). Further, regarding the second reel 102, when the code number “2” is selected with the lottery probability 12/96, “RED7” corresponding to the code number “2” of the second reel 102 is displayed in the middle of the display window 150 ( The symbols to be stopped are determined to be rearranged on the PAY LINE). In addition, regarding the third reel 103, when the code number “4” is selected with the lottery probability 5/154, “WILD” corresponding to the code number “4” of the third reel 103 is displayed in the middle of the display window 150 ( The symbols to be stopped are determined to be rearranged on the PAY LINE).

  Then, the main CPU 71 stores the determined three stop scheduled symbols of the first reel 101 to the third reel 103 in the symbol storage area provided in the RAM 73.

  Next, the main CPU 71 performs effect content determination processing (S15). The main CPU 71 extracts an effect random number value and determines one of a plurality of predetermined effect contents by lottery.

  Next, the main CPU 71 performs a symbol display control process (S16). In this symbol display control process, scrolling of the first reel 101, the second reel 102, and the third reel 103 is started, and after a predetermined time has elapsed, with respect to the first reel 101, the second reel 102, and the third reel 103, the process of S14 is performed. The three scheduled stop symbols determined in the normal game symbol lottery process are sequentially rearranged in the middle of the display window 150 (on the PAY LINE) at predetermined time intervals. That is, nine symbols including three symbols to be stopped are rearranged in the display window 150 (upper, middle, and lower). For example, when the scheduled stop symbol is “RED7” in the first reel 101, the scheduled stop symbol is “RED7” in the second reel 102, and the scheduled stop symbol is “WILD” in the third reel 103, the display window 150 “RED7”, “RED7”, and “WILD” are rearranged in the middle stage (on the PAY LINE).

  Next, the main CPU 71 performs a payout amount determination process (S17). In this process, the symbol combination table for the normal game (see FIG. 9) stored in the RAM 73 and the value of the BET counter (50 BET, 100 BET, 150 BET, 200 BET, 250 BET) are referred to on the PAY LINE or displayed. A payout based on the combination of symbols displayed in the window 150 is determined and stored in a payout amount storage area provided in the RAM 73. For example, when the value of the BET number counter is “50” and the combination of symbols displayed on the PAY LINE is a combination of three “3BARs”, the base game symbol combination table of FIG. 9 is referred to. “500” credits are determined as the payout and stored in the payout amount storage area provided in the RAM 73.

  Next, the main CPU 71 performs a payout process (S18). The main CPU 71 adds the value stored in the payout amount storage area to the value of the credit number counter provided in the RAM 73.

  Next, the main CPU 71 determines whether or not a free game trigger has been established (S19). Specifically, it is determined whether or not a winning including the “WILD” symbol is established on the PAY LINE. In the present embodiment, the “WILD” symbols are arranged only on the third reel 103, and replace the “RED7”, “BLUE7”, “3BAR”, “2BAR”, and “1BAR” types of symbols. Accordingly, whether or not the free game trigger is established is indicated on the PAY LINE by, for example, “WILD” such as “RED7”, “RED7”, “WILD”, “3BAR”, “2BAR”, “WILD” (ANY BAR). It is determined by whether or not a winning including the symbol is established.

  Further, for example, as shown in FIG. 19, when “BLUE7”, “BLUE7”, and “WILD” are rearranged on the PAY LINE, the “WILD” symbol that triggers the free game is displayed on the upper image display panel 131. Information such as winnings including and payout amounts to be awarded is displayed. Then, as shown in FIG. 20, the upper image display panel 131 displays a message “GOLD BONUS” for notifying that a free game trigger has been established, and also notifies by voice.

  When a winning including the “WILD” symbol is established on the PAY LINE and a free game trigger is established (S19: YES), a free game process described later is executed (S20).

  At this time, the payout amount given as a winning including the “WILD” symbol in the process of S17 is stored in the special payout storage area of the RAM 73 as “special payout”. For example, when the winning of “BLUE7” including the “WILD” symbol is established on the PAY LINE, the payout amount to be awarded is 1000 credits (when 50 credits are betted). Accordingly, the special payout storage area of the RAM 73 stores a value of “1000” as “special payout”.

  After the process of S20, or when a winning including the “WILD” symbol is not established on the PAY LINE and a free game trigger is not established (S19: NO), the process proceeds to S12.

(Bet / start check process)
Next, the bet / start check process will be described with reference to FIG.

  First, the main CPU 71 determines whether or not credit data has been received from the PTS device 700 (S41). The transmission of credit data from the PTS device 700 to the main CPU 71 is performed when an IC card is inserted into the card insertion slot and when the bill entry 60 accepts a regular bill.

  When determining that the credit data has been received (S41: YES), the main CPU 71 adds the amount indicated by the received credit data to the value stored in the credit number counter (S42).

  The main CPU 71 determines whether or not the value stored in the credit counter is 0 after S42 or when it is determined in S41 that no credit data has been received (S41: NO) (S43). ). When determining that the value stored in the credit counter is 0 (S43: YES), the main CPU 71 returns to the process of S41.

  On the other hand, when the main CPU 71 determines that the value stored in the credit counter is not 0 (S43: NO), the BET button (50-BET button 34, 100-BET button 35, 150-BET button 36, The operation acceptance of the 200-BET button 37 and the 250-BET button 38) is permitted (S44).

  Next, the main CPU 71 determines whether or not an operation of the BET button is detected (S45). The main CPU 71 detects that the BET button has been pressed by the player using a BET switch (50-BET switch 34S, 100-BET switch 35S, 150-BET switch 36S, 200-BET switch 37S, 250-BET switch 38S). If so (S45: YES), the value is added to the value stored in the BET number counter provided in the RAM 73 based on the type of the BET button (S46). On the other hand, when the operation of the BET button is not detected (S45: NO), the process returns to S44.

  Next, the main CPU 71 determines whether or not the value stored in the BET number counter is maximum (S47). When determining that the value stored in the BET number counter is maximum (S47: YES), the main CPU 71 prohibits updating of the value stored in the BET number counter (S48). The main CPU 71 permits operation acceptance of the spin button 46 after S48 or when it is determined that the value stored in the BET number counter is not the maximum in S47 (S47: NO) (S49).

  After S49, the main CPU 71 determines whether or not the operation of the spin button 46 is detected (S50). When determining that the operation of the spin button 46 has not been detected (S50: NO), the main CPU 71 proceeds to step S44.

  On the other hand, when the main CPU 71 determines that the operation of the spin button 46 is detected (S50: YES), the main CPU 71 subtracts the value of the BET number counter calculated in S46 from the value of the credit number counter ( S51).

  Then, the bet / start check process ends.

(Free game processing)
Next, free game processing will be described with reference to FIG.

  First, the main CPU 71 adds “5” to the value of the free game number counter in the RAM 73 (S101). Thereby, in the main control process (normal game), when a free game trigger is established, five free games (games that do not require a new bet) can be executed. The stock counter of the RAM 73 stores a value “1” as an initial value. The value of this stock counter is added when a free game retrigger described later is established.

  Next, the main CPU 71 executes a magnification determination lottery process (S102). In this magnification determination lottery process, the magnification “1 ×”, “1.5 ×”, the magnification “2 ×”, the magnification “2.5 ×”, and the magnification “3 ×” are determined by drawing with reference to the magnification table shown in FIG. ”, The magnification“ 4 times ”, the magnification“ 5 times ”, and the magnification“ 10 times ”are determined. Specifically, as shown in FIG. 13, the magnification “1 ×” is selected with a lottery probability “10/40”. The magnification “1.5 times” is selected with a lottery probability “8/40”. The magnification “2 times” is selected with a lottery probability “7/40”. The magnification “2.5 times” is selected with a lottery probability “5/40”. The magnification “3 times” is selected with a lottery probability “4/40”. The magnification “4 times” is selected with a lottery probability “3/40”. The magnification “5 times” is selected with a lottery probability “2/40”. The magnification “10 times” is selected with a lottery probability “1/40”. The selected magnification is stored in the RAM 73.

  At this time, on the upper image display panel 131, an effect display indicating that the magnification determination lottery process is being performed is performed. Specifically, as shown in FIG. 21, the upper image display panel 131 displays a blast effect in which a symbol related to winning (“BLUE7” in FIG. 21) including a “WILD” symbol that triggers a free game is displayed. A switch 201 and a gold bar 202 are displayed.

  Then, after the effect of pressing the blast effect switch 201 is performed, the gold ingot 202 is exploded and the value stored in the special payout storage area of the RAM 73 (“special payout”) as shown in FIG. A value obtained by multiplying the value of the magnification selected in the process of S102 is displayed. For example, when the value of “1000” is stored in the special payout storage area of the RAM 73 (“special payout”), and the value of the magnification selected in the process of S102 of the free game process is “double”, “ A value of “1000” × “2” = “2000” is displayed as the gold ingot 202 explodes.

  Thereafter, as shown in FIG. 22, the value displayed with the explosion of the gold ingot 202 is displayed at the center of the upper image display panel 131.

  Next, the main CPU 71 performs an initialization process at the end of one game, similarly to the process of step S12 (S103).

  Further, the bet number in the free game takes over the bet number selected in the bet / start check process (S13) in the normal game, that is, the value stored in the BET counter.

  Next, the main CPU 71 conducts free game symbol lottery processing (S104). Based on the probability (WEIGHT) defined in the free game symbol lottery table (see FIG. 12), the first reel 101, the second reel 102, and the third reel 103 are arranged in the middle of the display window 150 (on the PAY LINE). Three symbols to be stopped to be rearranged are determined by lottery.

  For example, when the code number “2” is selected for the first reel 101 with the lottery probability 6/98, “RED7” corresponding to the code number “2” of the first reel 101 is displayed in the middle of the display window 150 ( The symbols to be stopped are determined to be rearranged on the PAY LINE). Further, regarding the second reel 102, when the code number “2” is selected with the lottery probability 12/96, “RED7” corresponding to the code number “2” of the second reel 102 is displayed in the middle of the display window 150 ( The symbols to be stopped are determined to be rearranged on the PAY LINE). In addition, regarding the third reel 103, when the code number “4” is selected with the lottery probability 5/154, “WILD” corresponding to the code number “4” of the third reel 103 is displayed in the middle of the display window 150 ( The symbols to be stopped are determined to be rearranged on the PAY LINE).

  Then, the main CPU 71 stores the determined to-be-stopped symbols for the free game on the first reel 101 to the third reel 103 in a symbol storage area provided in the RAM 73.

  Next, the main CPU 71 performs effect content determination processing (S105). The main CPU 71 extracts an effect random number value and determines one of a plurality of predetermined effect contents by lottery.

  Next, the main CPU 71 performs a symbol display control process (S106). In the symbol display control process in the free game process, as shown in FIG. 25, scrolling of the first reel 101, the second reel 102, and the third reel 103 is started. With respect to the reel 102 and the third reel 103, the three scheduled stop symbols determined in the free game symbol lottery process of S104 are sequentially rearranged in the middle stage of the display window 150 (on the PAY LINE) at predetermined time intervals. That is, nine symbols including three symbols to be stopped are rearranged in the display window 150 (upper, middle, and lower). For example, when the scheduled stop symbol is “RED7” in the first reel 101, the scheduled stop symbol is “RED7” in the second reel 102, and the scheduled stop symbol is “WILD” in the third reel 103, the display window 150 “RED7”, “RED7”, and “WILD” are rearranged in the middle stage (on the PAY LINE).

  Next, the main CPU 71 conducts a payout number determination process (S107). In this process, the symbol combination table for free games stored in the RAM 73 (see FIG. 10) and the value of the BET number counter (50 BET, 100 BET, 150 BET, 200 BET, 250 BET) are referred to or displayed on the PAY LINE. A payout based on the combination of symbols displayed in the window 150 is determined and stored in a payout amount storage area provided in the RAM 73. For example, when the value of the BET number counter is “50” and the combination of symbols displayed on the PAY LINE is a combination of three “3BAR”, the free game symbol combination table of FIG. 10 is referred to. “500” credits are determined as the payout and stored in the payout amount storage area provided in the RAM 73.

  Next, the main CPU 71 performs a payout process (S108). The main CPU 71 adds the value stored in the payout amount storage area to the value of the credit number counter provided in the RAM 73.

  Next, the main CPU 71 determines whether or not there is a symbol “F_COIN” among the nine symbols rearranged in the display window 150 (S109). If there is a symbol “F_COIN” (S109: YES), a special payout determination payout process is executed (S110). In this special payout determination payout process, the magnification selected in the process of S102 with respect to the value ("special payout") stored in the special payout storage area of the RAM 73 when the free game trigger is established in the process of S19. And the value obtained by multiplying the number of “F_COIN” rearranged in the display window 150 is added to the value of the credit number counter provided in the RAM 73 as a free game payout.

  For example, in the base game, a winning of “BLUE7” including the “WILD” symbol is established (when 50 credits are bet), and a value of “1000” is stored in the special payout storage area of the RAM 73 (“ Special payout ”), and when the value of the magnification selected in S102 of the free game process is“ 2 times ”and the number of“ F_COIN ”rearranged in the display window 150 is“ 2 ”, the free game The payout has a value of “1000” × “2” × “2” = “4000” credits. Accordingly, “4000” credit is added to the value of the credit number counter provided in the RAM 73 as a free game payout.

  In addition, as shown in FIG. 26, when the symbol “F_COIN” is included in the symbols rearranged in the display window 150, the rearranged symbol “F_COIN” moves upward and rotates. Is executed. Thereafter, as shown in FIG. 27, the free game payout is added and displayed on the bonus win meter.

According to the above configuration, in a free game that shifts from a normal game, a free game payout that is awarded when the symbol “F_COIN” (predetermined symbol) is rearranged in the display window 150 is a free game in the normal game. This is determined based on the “special payout” given to the winning including the “WILD” symbol when the trigger is established.
Conventionally, since the base game and the free game are performed independently, the payout is also given independently. However, according to the above configuration, the free game payout is paid at the time of transition from the base game to the free game. It can depend on or be associated with the “special dividend” awarded. Thereby, the monotonousness of the payout in the free game can be improved.
In addition, since the free game payout is based on the “special payout” in the normal game, the free game payout can give the player the impression that the “special payout” in the normal game is repeated. It becomes possible to improve the monotony of the dividend in the game.

  In the above description, a value obtained by multiplying the “special payout” by the scale determined by the scale determination lottery process is awarded as a free game payout. As a result, even when the free game trigger is established in the same manner in the base game, different values may be given as the free game payout, and the monotonousness of the payout in the free game can be further improved.

  Next, the main CPU 71 determines whether or not the free game retrigger has been established (S111). The free game retrigger condition in the present embodiment is the same as the free game trigger, and is determined by whether or not a winning including the “WILD” symbol is established on the PAY LINE. In the present embodiment, whether or not the free game retrigger has been established is indicated on the PAY LINE as, for example, “RED7”, “RED7”, “WILD”, “3BAR”, “2BAR”, “WILD” (ANY BAR). , Whether or not a winning including the “WILD” symbol is established.

    When the main CPU 71 determines that a winning including the “WILD” symbol is established on the PAY LINE and the retrigger of the free game is established (S111: YES), “1” is added to the stock counter of the RAM 73. (S112).

  Next, the main CPU 71 subtracts “1” from the value stored in the free game number counter when determining that the retrigger is not established (S111: NO) or after the processing of S112 (S113).

  At this time, as shown in FIG. 23, display is performed by subtracting “1” from the value of the free game number counter 205 displayed on the upper image display panel 131. For example, as shown in FIG. 23, when the value of the free game number counter 205 is “5”, “1” is subtracted and the value “4” is displayed on the free game number counter 205. Further, the value of the subtracted free game number counter 205 is notified by voice as the number of remaining free games to be executed. Also, as shown in FIG. 24, each time “1” is subtracted from the value stored in the free game number counter, the value of the free game number counter 205 decreases, and the remaining free game number disappears. When the last free game is reached, the display of the free game number counter 205 is turned off.

  Next, the main CPU 71 determines whether or not the value stored in the free game number counter is “0” (S114). When determining that the value stored in the free game number counter is not “0” (S114: NO), the main CPU 71 proceeds to the process of S103.

  On the other hand, when it is determined that the value stored in the free game number counter is “0” (S114: YES), the main CPU 71 subtracts “1” from the value stored in the stock counter (S115). ).

  Next, the main CPU 71 determines whether or not the value stored in the stock counter is “0” (S116). When determining that the value stored in the stock counter is not “0” (S116: NO), the main CPU 71 proceeds to the process of S101.

  On the other hand, when it is determined that the value stored in the stock counter is “0” (S116: YES), the free game process is terminated.
