PROBLEM TO BE SOLVED: To easily control ball appearance by successively stop-displaying after the lapse of a selected base varying time after starting the variation of each pattern and differentiating the selecting ratio of each base varying time corresponding to the number of starting storage and a game state so as to easily estimate a ball appearing ratio per a unit time. SOLUTION: In a Japanese pinball game machine 1, a base varying time is fixed without regard to a normal game state (a low probability state) or a big winning state or a high probability state when a 'li-zhi' pattern is displayed after starting the variation of patterns. When the 'li-zhi' pattern is not displayed, the machine 1 selects one base varying time from among at least two kinds of base varying time of different length. Then, after the lapse of a selected base varying time after respective patterns displayed in the respective display areas 10 to 12 of a pattern display part 3 start variation, the stop display is successively executed and the selecting ratio of the each varying time is differentiated corresponding to the number of starting storages and a game state. |
