<p>PROBLEM TO BE SOLVED: To substantially synchronize the performance timing of a plurality of game machines installed in island equipment.SOLUTION: A method of controlling performance of a game machine having a main control board and a sub control board executes the steps of: determining an event start time and storing the time in a memory, the determination being made on the basis of a reference clock obtained from an RTC (real time clock) information of the main control board or the sub control board, and on the basis of an event start time interval; and referring to the RTC after an operation start-up of the game machine, and starting an event processing operation prepared in advance when event start time stored in a memory comes. The game machine comprises a token insertion-payout number difference counter and a plurality of lottery tables having different winning probabilities, the game machine executing a lottery when the event start time comes, the lottery being executed with one table selected among a plurality of lottery tables having different winning probabilities on the basis of a token number difference during an event counted by the token insertion-payout number difference counter.</p> |
