Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a relay device and a prize exchange system such that a certain exchange of information including a ball number can be secured when introducing a holding ball system managing the number of holding balls capable of being used only on that day and a stored ball system managing the number of stored balls capable of being used on and after that day.SOLUTION: When a relay device 10 transmits the number of holding balls acquired from a holding server 20 to a prize exchange device 40 (Sb21), the relay device 10 performs processing (Sb15) for making the number of the holding balls of the holding ball server zero, and when receiving the number of the holding balls after processing from the prize exchange device having performed prize exchange processing (Sb31) and having performed processing to reduce the number of the holding balls (Sb32), performs processing (Sb41) for updating the number of the holding balls of the holding ball server to the number of the holding balls after the processing. |
