发明名称 PLAYING DISC
摘要 <p>A plurality of playing discs adapted to be used in a game in which one playing disc is thrown against a stack of other playing discs, in an attempt to dislodge and upset the discs in the stack. Each playing disc is uniform and characterized by a central depressed area in the top face of each disc, and preferably, a plurality of circumferentially spaced intermediate recesses between the central depressed area and an outer rim of uniform thickness, such central depressed area and recesses creating pockets between adjacent stacked discs, so that the air in the pockets is compressed by the flexing wall portions of adjacent discs struck by a thrown playing disc, the compressed air being expanded after the impact in order to assist thrusting an upper playing disc away from the stack.</p>
