PROBLEM TO BE SOLVED: To provide a game machine which reduces excessive sound output.SOLUTION: A sound-outputting Pachinko machine 10 comprises: an amplifier 275' for amplifying a sound signal; a sound control CPU 542 for controlling an amplification amount of the amplifier 275'; a peak hold part 291 for periodically holding the maximum value of the amplified sound signal; a first comparator 292' for comparing the held maximum value with a predetermined first threshold; and a second comparator 547 for comparing a predetermined second threshold larger than the first threshold with the maximum value. The sound control CPU 542 reduces the amplification amount on the basis of the results of discrimination by the first comparator 292' and the second comparator 547. |
