In the gaming machine according to the present invention, when symbols are displayed within display regions of a display means, a determination means determines, from a combination of symbols displayed, establishment/non-establishment of the shift condition. More specifically, the determination means determines that the shift condition is established when a predetermined number or more first symbols are displayed within the at least one display regions. Further, a condition control means for controlling, when the first symbols displayed within the at least one display regions are less than the predetermined number and when a second symbols are displayed within the display regions, to establish the shift condition by the first symbols and the second symbols. Accordingly, even when the first symbols displayed within the display regions are less than predetermined number, the player can look forward to the shift to the bonus game and therefore feel interest more than in a conventional gaming machine.
