Abstract: To improve the amusement of game players toward games.SOLUTION: In a Pachinko machine 1, when the number of rounds of consecutive wins has reached 4 [rounds], compared to before the number of rounds of consecutive wins has reached 4 [rounds], as a variation pattern regarding a variable display of second special symbols, a probability of a variation pattern belonging to a "variation mode C" being selected becomes high. Thus, when the number of rounds of consecutive wins has reached 4 [rounds], compared to before the number of rounds of consecutive wins has reached 4 [rounds], a short variation time is likely to be selected. Further, after the number of rounds of consecutive wins has reached 4 [rounds], compared to before the number of rounds of consecutive wins has reached 4 [rounds], a probability of a special bonus display being performed as a bonus display becomes high. Thus, when the number of rounds of consecutive wins has reached 4 [rounds], compared to before the number of rounds of consecutive wins has reached 4 [rounds], appearance frequency of the special bonus display is improved.SELECTED DRAWING: Figure 46
