Abstract
Abstract A playing surface for a billiard type of game comprises three straight ball rebound sides and one parabolic ball rebound side extending upwardly, inwardly and around the periphery of the playing surface. The playing surface and all sides have a nap or felt covering. A number of fixed obstacles on the surface are located at strategic locations to compound playing difficulty. Counting discs are threaded to rails outside of the playing surface, attached to the rebound sides and are used to keep score.
