PROBLEM TO BE SOLVED: To provide a game machine capable of varying a result of prior determination of winning and losing when a winning probability varies between a high-probability state and a low-probability state at a sub-board side.SOLUTION: A main control unit 14 stores a winning determination random number for determining a jackpot or losing of first and second special symbol games until the first and second special symbol games are performed, based on first and second start winning signals. The main control unit 14 compares the stored winning determination random number with a jackpot determination value registered in a low-probability determination table having a low jackpot probability and a high-probability determination table having a high jackpot probability. As a prior determination result, information for indicating one of winning at the time of a low probability, winning at the time of a high probability, and losing at the time of a low probability and a high probability is outputted. A pattern control unit 23 changes a prior notice performance in a shift from a high probability to a low probability.SELECTED DRAWING: Figure 2 |
