<p><P>PROBLEM TO BE SOLVED: To provide a game machine for executing a presentation utilizing a visual illusion by enabling rolling of a game ball on a stage to have an element of surprise. <P>SOLUTION: The stage 220 includes: a light transmissive member 250 constructing a rolling surface of a game ball; and a pseudo rolling member 270 that is arranged below the light transmissive member 250 and constructs a pseudo rolling surface 270a visible via the light transmissive member 250. Rolling surfaces 230a, 240a include front recessed grooves 222a-222c and rear recessed grooves 223a-223c inclined to lead the game ball from an upper position to a lower position. The pseudo rolling surface 270a includes decorative recessed grooves 272a-272c inclined along the rolling surfaces 230a, 240a at positions corresponding to the front recessed grooves and rear recessed grooves. For the front recessed grooves, rear recessed grooves, and decorative recessed grooves, at least one of an inclination angle, an inclination direction, a curvature, and an inclination position with respect to the leading direction of the game ball differs. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
