PROBLEM TO BE SOLVED: To provide a game machine which can raise an expectation degree with which to execute a special game by a specific performance mode being developed.SOLUTION: There is a specific performance mode in which to suggest jackpot winning expectation degree on the basis of a prior determination result. There are at least provided as specific performance modes: a first specific performance mode (read-ahead zone performance 12); a second specific performance mode (read-ahead zone performance 11) which can be developed from the first specific performance mode and is higher in expectation degree with which to execute a special game than the first specific performance mode; and a third specific performance mode different from the first specific performance mode and the second specific performance mode. The second specific performance mode is higher in expectation degree with which to execute the special game than the third specific performance mode.SELECTED DRAWING: Figure 99 |
