PROBLEM TO BE SOLVED: To enable an inexperienced game player to easily win a prize so as to improve the game interest by increasing the number of patterns which can appear on the prize winning line by varying the rotating speed of a rotary drum and stop the rotary drum at a predetermined stop rotation angle when a stop directing means is operated. SOLUTION: When a medal is thrown in and a start lever 12 is pulled to rotate three rotary drums 6, a lottery is held, a pattern combination is selected with designated probability, and according to the pattern combination, it is decided whether it is prize winning or not. When it becomes internal prize winning state, on sequentially pressing stop buttons 13 to stop the rotary drums 6, the stop rotation angle of each rotary drum 6 is decided so that the rotary drums 6 are stopped in designated frame number positions. In the case where there is no pattern of internal prize winning or the internal prize winning is not obtained, however, it is decided that the rotary drums are stopped in suitable pattern frame number positions, kept away from another prize winning pattern. After that, the rotating speed control characteristic for stopping the drums is selected depending on which frame they are stopped to conduct the patten stop control. |
