PROBLEM TO BE SOLVED: To provide a game machine which does not adjust a sound volume depending on an effect sound to be generated by the game machine itself in the game machine, which has an environmental microphone for collecting an ambient sound, and adjusts the volume of the effect sound in accordance with the loudness of the sound collected by the environmental microphone. SOLUTION: A Pachinko and slot game machine (1) includes: a sub-CPU (81) for commanding the generation and stop of the effect sound; speakers (9L, 9R) for emitting the effect sound, based on the command; the environmental microphone (28) for collecting the ambient sound; an ambient sound level amplifier (92) for amplifying the collected ambient sound; and a gain adjuster (93) for adjusting the amplification factor of an amplifier (91) in response to the amplified level. When the speakers emit the effect sound, the environmental microphone starts the collection of the ambient sound after the termination of emission of the effect sound and after the passage of a delay time till the physical vibration of the speakers is stopped and the passage of a reverberation time till the termination of a reverberation inside the Pachinko and slot game machine.
