Have. The D / A converter 210 has a plurality of output terminals 210a, 210b, and 210c. The output terminals 210 a, 210 b, and 210 c output in parallel the sound signals converted into the analog format in the D / A converter 210. Specifically, the output terminal 210a outputs an analog BGM signal, the output terminal 210b outputs an analog functional sound signal, and the output terminal 210c outputs an analog sound effect signal.

  The sound signal output device 201 is connected so as to input a plurality of sound signals to the volume level changing device 211. The volume level changing device 211 includes a first adder 205, a signal switching unit 203, a plurality of low-pass filters 204a, 204b, and 204c, and a second adder 207.

The volume level changing device 211 can switch the sound range in which the volume level of the sound signal on which the BGM signal and the functional sound signal are superimposed is changed by a switching signal. As a result, the information output unit 116 reads various data from the game information storage unit 117 and outputs the data to the volume level changing device 211, thereby reducing the volume of the sound in the predetermined range selected based on the switching signal. Output from the amplifier 206 and the speaker 29.

  Each block of the game controller 100 may be formed by hardware, or may be formed by software as necessary.

(Operation of the game controller 100)
In the above configuration, the operation of the game controller 100 will be described.
When a game start signal is output from the game start unit 109 by a player's operation, the symbol determination unit 104 starts processing, and the game execution unit 110 starts a unit game, thereby starting rearrangement of the symbols 180. (Second process). The symbol determination unit 104 performs determination by randomly selecting the scatter target symbol 181 from the plurality of symbols 180 stored in the symbol storage unit 108 (first process). Then, the determined scatter target symbol 181 is stored in the scatter target symbol storage unit 105 and used for the determination process in the rearrangement number determination unit 114.

  The scatter object symbol 181 stored in the scatter object symbol storage unit 105 is output to the display symbol storage unit 107 and then used for image processing in the display control unit 102 to be displayed in the display area 101 b of the display unit 101. Is done. That is, the game controller 100 executes the fifth process of providing the display area 101b in a portion different from the arrangement area 101a where the symbols 180 are arranged, and displaying the scatter object symbol 181 in the display area 101b. Thus, the player can easily recognize that the scatter object symbol 181 is displayed because the scatter object symbol 181 is displayed in the display area 101b in a state separated from the arrangement area 101a.

  Further, when the symbols 180 are rearranged by the execution of the unit game, the rearrangement number determination unit 114 identifies the scatter target symbols 181 from the rearranged symbols 180 and determines the rearrangement number of the scatter target symbols 181. Ask. When a predetermined number or more of the scatter target symbols 181 are rearranged, the scatter target symbols 181 are set as the scatter symbols 182. That is, the scatter object symbol 181 stored in the scatter object symbol storage unit 105 is transferred to the scatter symbol storage unit 106. As a result, the scatter target symbol 181 functions as the scatter symbol 182.

  When the scatter symbol 182 is set, the information output unit 116 reads character data, payout number data, and explanation data associated with the scatter symbol 182 from the game information storage unit 117. These data are output to the display control unit 102. Then, the contents of the payout determined based on the scatter symbols 182 rearranged on the payline L and outside the payline L are notified, and a payout is awarded (fourth process). Further, the above data is output to the volume level changing device 211 and output from the speaker 29 as sound.

  When the game is executed as described above, a function sound indicating the start of the game is output at the start of the game, and a function sound indicating that the payout is in progress is output when the payout is paid out. In addition to the above functional sounds, background sounds are output. At this time, the sound volume level changing device 211 reduces the sound volume for the high sound range selected by the sound range setting unit 230. Thereby, in the player, it is difficult to hear the high-frequency sound, so that the player's discomfort due to the high-frequency sound can be reduced. In addition, when the sound range setting unit 230 is operated, the sample sound including the background sound and the functional sound is output, so that the volume level can be easily adjusted.

  As a result, as shown in FIG. 2, the sample sound data passes through the main body PCB 60 and is output to the D / A converter 210, thereby being converted into an analog signal form. Then, the BGM signal is output from the first output terminal 210a of the D / A converter 210, and the functional sound signal is output from the second output terminal 210b. The BGM signal and the functional sound signal are combined in the first adder 205 and then passed through a connection path corresponding to the switching signal in the signal switching unit 203, whereby the low-pass filters 204a, 204b, It is output to 204c.

  In the low-pass filters 204 a, 204 b, and 204 c, the volume of a predetermined sound range is reduced, and then the sound passes through the second adder 207 and is output to the volume amplifier 206. Then, the sample sound with the volume of the predetermined sound range lowered is output from the speaker 29 and heard by the player who operated the first to third selection switches 221, 222, and 223. The player determines whether the sound quality of the sample sound is appropriate. If the player is not satisfied with the sound quality, the player can audition the sound quality of the next sample sound by operating the other first to third selection switches 221, 222, 223. Can be adjusted to the desired sound quality.

(Processing operation)
Next, a process performed in the slot machine 10 in which the sound quality is adjusted as described above will be described. As the main CPU 41 reads out and executes the game program, the game proceeds. As shown in FIG. 7, in the game execution process, it is determined whether or not a coin is bet (S10). In this process, it is determined whether or not an input signal from the 1-BET switch 26S is received when the 1-BET button 26 is pressed, and the maximum BET switch 27S is pressed when the maximum BET button 27 is pressed. It is determined whether an input signal has been received. If the coin is not bet (S10, NO), S10 is re-executed to enter a standby state until it is bet.

  On the other hand, when a coin is bet (S10, YES), the number of credits stored in the RAM 43 is subtracted according to the number of coins bet (S11). If the number of coins bet is larger than the number of credits stored in the RAM 43, S11 is re-executed without performing the process of subtracting the number of credits. Further, when the number of coins bet exceeds the upper limit (50 in this embodiment) that can be bet on one game, the process of subtracting the credit number is not performed. S12 is executed.

  Next, it is determined whether or not the spin button 23 is turned on (S12). If the spin button 23 is not turned on (S12, NO), the process returns to S10. When the spin button 23 is not turned on (for example, when an instruction to end the game is input without the spin button 23 being turned on), the subtraction result in S11 is cancelled.

  On the other hand, when the spin button 23 is turned on (S12, YES), symbol determination processing is executed (S13). That is, by executing the stop symbol determination program stored in the RAM 43, the symbols 180 to be stopped at each stage of the 15 display windows 151 to 155 are determined. As a result, a combination of symbols to be stopped on the payline L is determined.

  Thereafter, the symbols 180 in the display windows 151 to 155 are scroll-displayed (S14). In this scroll process, after the symbol 180 is scrolled in the direction of the arrow, the symbol 180 determined in S13 is stopped (rearranged) in the display windows 151 to 155.

  Thereafter, a scatter target symbol determination process is executed (S15). That is, the scatter target symbol 181 is randomly determined from the symbols 180 of “BELL”, “CHERRY”, “STRAWBERRY”, “PLUM”, “ORANGE”, and “APPLE”. Then, the determined scatter object symbol 181 is displayed on the scatter object symbol display unit 163.

  When the scroll of the symbol 180 is stopped, the rearrangement number of the scatter object symbol 181 is acquired (S16). Thereafter, it is determined whether or not the number of rearrangements is equal to or greater than a set threshold value (S17). If it is equal to or greater than the set threshold value (S17, YES), the scatter object symbol 181 is set as the scatter symbol 182. Specifically, after the scatter object symbol 181 moves from the scatter object symbol display unit 163 to the scatter symbol display unit 171 and is accommodated in the scatter symbol display unit 171, a scatter symbol display unit is performed. It is displayed in a state stored in 171 as a stored item (S18).

  Thereafter, the character 251 is displayed between the scatter symbol display unit 171 and the scatter object symbol display unit 163, and a balloon frame indicating the conversation content of the character 251 is displayed. Further, the conversation content of the character 251 is output as voice. Specifically, the first explanation image 252 “ORANGE has become a scatter symbol” is displayed in the balloon frame and is output as a sound (S19).

  Thereafter, a payout process is executed. That is, the coin payout number based on the winning combination and the coin payout number based on the display number of the scatter symbols 182 are added together. When storing coins to be paid out, a predetermined number of credits are added to the number of credits stored in the RAM 43. On the other hand, when coins are paid out, a predetermined number of coins are paid out by transmitting a control signal to the hopper 66 (S20).

  On the other hand, if the number of rearrangements is not equal to or greater than the set threshold value (S17, NO), it is determined whether or not the combination of symbols 180 stopped on the payline L is a winning combination (S23). If it is not the winning combination (S23, NO), since neither the scatter symbol 182 nor the winning combination is found, this routine is terminated as a loss.

  On the other hand, when it is a winning combination (S23, YES), S20 described above is executed. Thereafter, it is determined whether or not a bonus trigger is established as a winning combination. That is, it is determined whether or not the combination of “APPLE” is arranged on the payline L (S21). If it is determined that the bonus trigger is established (S21, YES), the bonus game process is executed. (S22). On the other hand, if the bonus trigger has not been established (S21, NO), the routine is terminated as a loss.
