<P>PROBLEM TO BE SOLVED: To provide a member management system capable of appropriately reflecting the past game result of a player on an exchange rate. <P>SOLUTION: The exchange rate of a member after storing balls is decided by averaging the exchange rate before storing the balls and the exchange rate of this time. The exchange rate of this time is decided by the income and expenditure of the member of the day. Thus, since the gift exchange rate of the member is raised when the member keeps losing and the gift exchange rate of the member is lowered when the member keeps winning, the past game result of the member is appropriately reflected on the exchange rate. <P>COPYRIGHT: (C)2004,JPO |
