<P>PROBLEM TO BE SOLVED: To provide a pinball game machine capable of preventing a time-shortening game from becoming uniform. <P>SOLUTION: When a winning symbol stops on a symbol display device, a big-win game is performed, and after the end of the big-win game, the time-shortening game starts. If the big-win game starts during the time-shortening game, the number of times of symbol variation displays which are performed during the time-shortening game by the symbol display device (a variation frequency during time shortening) is stored. The upper limit of duration of the time-shortening game, which is started after the end of the big-win game, is set to the variation frequency during time shortening stored. Thereby, the upper limit of duration of the time-shortening game can be changed diversely so as to prevent the time-shortening game from becoming uniform. The variation frequency during time shortening is stored only when the big-win game occurs during the time-shortening game and the stored variation frequency during the time shortening is set as the upper limit of duration of the next time-shortening game, so that control of the game machine is not complicated. <P>COPYRIGHT: (C)2012,JPO&INPIT |
