To provide a game parlor system capable of preventing a clever issuing processing attacking a blind spot of a conventional structure intended to sell/buy game media.

When a jackpot is made after the issuing processing, a suppression flag for the record corresponding to the issuing processing is 1 to restrain the issuing processing thereafter. The issuing processing thereafter is permitted on condition that an own ball ticket issued in the issuing processing is received (the suppression flag is 0). With this structure, execution of the issuing processing in a ready-to-win state can be specified, and by executing the issuing processing, the processing of receiving the own ball ticket issued thereafter is restrained, so that the widespread fraudulence such as the trade of own balls can be prevented.
