PROBLEM TO BE SOLVED: To provide a game machine capable of improving the interest of a game by using one rotary drum for judging the generation of a special game state such as probability variable control or the like in the variable display device of a double drum structure. SOLUTION: A rotary drum mechanism 34 is constituted of respective left, outer middle and right drums 35-37 for deciding the presence/absence of the generation of a specified game state (the lead-out of a large winning pattern) by the display result of a special pattern and an inner middle drum 38 for forming the double drum structure with the outer middle drum 36. Then, the generation of the probability variable control (special game state) is judged by plural background patterns arrayed along the circumferential surface of the inner middle drum 38. Thus, the double drum structure used only for increasing a pattern combination number on display before is used for judging the generation of the special game state and further, the interest of the game is improved. |
