PROBLEM TO BE SOLVED: To execute a read-ahead forenotice performance without impairing taste of a promotion performance.SOLUTION: In a case where a read-ahead result that a special symbol display result turns out a "jackpot" is stored in a read-ahead result notification command reception buffer, when a jackpot type corresponding to the special symbol display result is "normal", a game machine executes a read-ahead failure performance, and, when the jackpot type is a "probability variation" "without any promotion performance", executes a read-ahead success performance. However, when the jackpot type is a "probability variation" "with the promotion performance, similar to a case where the jackpot type is "normal", the game machine executes the read-ahead failure performance. Thereby, the game machine can execute the read-ahead performance without impairing the performance effect by a promotion performance during the jackpot. |
