PROBLEM TO BE SOLVED: To efficiently change a performance mode.SOLUTION: A management server and a game machine respectively store synchronous update data as data that has been generated by the management server and is updated synchronously. The management server transmits a password including identification data capable of identifying the stored synchronous update data to a mobile phone, etc. of a player. When a value of the identification data extracted from the password input by the player is equal to or greater than that of the identification data stored in an identification data storage area, the game machine changes a performance pattern of a demonstration performance or adds a feasible premium performance according to the value of the extracted identification data. |
