PROBLEM TO BE SOLVED: To prevent trouble such as confusion of a player in waiting for prize exchange as much as possible, when the number of acquisition obtained by counting acquired game media is issued during an uncommunicable state. SOLUTION: Data of acquisition balls acquired by the player are put into a ball counter. The ball counter counts the acquisition ball data and issues a card for specifying the counting result (the acquisition ball data). An acquisition ball control server performs centralized control of the counting result data. When the card for specifying the counting result is issued from the off-line ball counter, the card with off-line issuing data recorded therein is discharged. When the off-line issuing data are not recorded in the received card in performing the prize exchange by using the acquisition ball data of the issued card, a POS terminal makes an inquiry to the acquisition ball control server (S169) and asks the return of an adequacy authentication result (S171). When the authentication result is not determined yet (NO in S171) since the POS terminal is in an off-line state, the prize exchange is performed after waiting for the permitting operation of an operator (S171b).
