<p>PROBLEM TO BE SOLVED: To provide a game machine system allowing an external device to perform a predetermined operation by using a specific sound outputted from a game machine.SOLUTION: A game machine system 900 includes a slot machine 1 and a portable terminal machine 710. The slot machine 1 includes a main control board 100 and a sub-control board 200. The sub-control board 200 includes an image acoustic generation board 400 capable of outputting sound, and a performance control board 300 for allowing the image acoustic generation board 400 to output a specific sound according to predetermined conditions. The performance control board 300 reduces volume of sound other than the specific sound such that the sound volume is made smaller when the image acoustic generation board 400 outputs the specific sound than when the specific sound is not being outputted. The portable terminal machine 710 includes sound recognition means 7115 for acquiring the specific sound, and is configured to execute a predetermined operation when acquiring the specific sound.</p> |
