PROBLEM TO BE SOLVED: To provide a game machine capable of remarkably improving the amusement of a game by implementing various performances.SOLUTION: A game area formation plate 103 is formed from a transparent material and behind the game area formation plate 103, a symbol display device is provided. Between the game area formation plate 103 and the symbol display device, a display area variable device 150 is provided. The display area variable device 150 includes a plurality of shields 152 which are provided in a rotatable manner. In an outer peripheral part of each shield 152, a plurality of outer peripheral surfaces 152a-152c are provided in parallel in a direction of rotation and formed continuously so as to generate corner portions in boundaries. The outer peripheral surfaces 152a-152c are formed in such a manner that length dimensions between boundaries with neighboring outer peripheral surfaces become different from each other. A series of shield surfaces are formed by combining the outer peripheral surfaces 152a-152c of each shield 152, and on the basis of a change in a width dimension of the shield surface, an area of a series of shield regions on a display screen of the symbol display device is changed. |
