发明名称 THREE PLAYER CHESS BOARD
摘要 A game board for simultaneous play of chess or the like by three players. The board is in the shape of a hexagon and is divided by transverse and longitudinal lines into three discrete territories, each of which territories includes 32 play spaces. Each territory includes a base defined by a side of said hexagon, side borders defined by half of each of the sides of the hexagon adjacent the base and frontier borders defined by lines extending from the terminal ends of the sides remote from the base to the geometric center of the hexagon. Each territory is defined into 32 play spaces by longitudinal lines extending from the base to the frontier borders and transverse lines extending from the sides to an apex line running from the center of the base.
