Abstract: PROBLEM TO BE SOLVED: To provide a game machine capable of determining an arbitrary time period of stop displays of first identification symbols, at an arbitrary number of times of variation of the identification symbols after a shift is made to a non-time-shortened state.SOLUTION: On the basis of a ball entrance to a first start port 20, after variable displays, a pachinko game machine 1 can stop display of a special symbol 1 (first identification symbols) and on the basis of a ball entrance to a second start port 21, after variable displays, can stop display of a special symbol 2 (second identification symbols). After a big win game, games can be controlled in a time-shortened state in which variation time of the special symbol (special symbol 1 or special symbol 2) is more likely to become shorter than in a non-time-shortened state. If a shift is made from a time-shortened state after a big win game to a non-time-shortened state, regardless of total variations of variations of the special symbol 1 and variations of the special symbol 2 from the time point of the end of the big win game, stop time of the special symbol 1 is determined by using a third special variation pattern determination table, on the basis of the total variations from the time point of the shit to the non-time-shortened state.SELECTED DRAWING: Figure 12
