PROBLEM TO BE SOLVED: To provide a Pachinko game machine in which a frequency of chance point performance can be changed without complicating a process of the main control part. SOLUTION: Whether a reservation of special symbol games remains or not is confirmed upon carrying out a performance. When the reservation remains, a performance symbol is variably displayed and then stopped and displayed at a chance point. Then, a development performance is carried out at a variation carried out after consuming the reservation. Then, because the development performance is carried out immediately after the stop-display at the chance point, a player can be made to think as if a chance point performance is carried out. Because performance is carried out in two variation times, there is no need to select a long variable time like a chance point performance. As a result, a performance similar to the chance point performance is possible without making the control of the main control part to carry out selection of a variation time more complex. The change of the generation frequency can be easily made because it can be performed regardless of a length of variation time. COPYRIGHT: (C)2011,JPO&INPIT
