PROBLEM TO BE SOLVED: To provide a prize exchanger which enhances capacity of gathering customers by reducing burden on a game parlor. SOLUTION: When an exchange demand for exchanging a storage game medium for prizes is transmitted to a prize seller computer system 40 from a computer system for exchange for prizes, the prize seller computer system 40 transmits the billing of the prize to a computer system 50 for settlement and the computer system 50 for settlement transmits a payment to the prize seller computer system 40 to get the exchange for the prizes established. This eliminates the need for previously buying by game parlors the prizes hard to buy for the game parlors, for example, those rarely demanded in the exchange of storage game media and costly and hard to preserve such as perishable foods. |
