PROBLEM TO BE SOLVED: To suitably enhance expectation feeling of players due to performances of presentations.SOLUTION: On the basis of passages of a plurality of game balls through a second start winning port that has changed to an open state, continuation presentations having different reliability for a big win corresponding to different presentation modes are performed over variable displays in a plurality of number of times. After that, corresponding to the number of second special symbol reservation storages that shows the number of game balls passed through the second start winning port, the presentation modes in the continuation presentations are changed. When this change is performed, a change to a presentation mode having a low probability for the big win is restricted. Also, corresponding to normal electric operation patterns in which the second start winning port is changed to the open state, a determination probability as to whether or not to perform the continuation presentation is arranged different.SELECTED DRAWING: Figure 23 |
