PROBLEM TO BE SOLVED: To improve game amusement in a game machine executing a limited probability-variable game.SOLUTION: This game machine is adapted to produce a high-probability opening extension state for improving a probability of stationarily displaying lottery symbols at big win symbols and at the same time improving a frequency of opening an operation-start hole, after an end of a big win game; shift it to a high-probability regular state when the lottery symbols are not stationarily displayed at the big win symbols during being variably displayed in the high-probability opening extension state a first predetermined number of times; and shift to a low-probability regular state when the lottery symbols are not stationarily displayed during being variably displayed in the high-probability regular state a second predetermined number of times. When determining a variation pattern of the lottery symbols, this game machine is adapted to use a high-probability time-shortened variation pattern table in the high-probability opening extension state, use a second high-probability regular variation pattern table after using a first high-probability regular pattern table in the high-probability regular state and use a low-probability regular variation pattern table in the low-probability regular state. |
