PROBLEM TO BE SOLVED: To provide a reel-type game machine capable of reflecting the skill of a player in the determination of the operation of a game state advantageous to the player. SOLUTION: When a combination of specific symbols related to the operation of a bonus game is displayed in a first mode, a lottery state is determined which is different from the first mode and in which the probability of determination of operation of the advantageous state for the player is higher than when the combination is displayed in a second mode. If the bonus game is operated, whether the game state advantageous to the player should be operated or not is determined based on the determined lottery state. It is announced to the player that the combination of the specific symbols can be displayed in the first mode. COPYRIGHT: (C)2009,JPO&INPIT
