Abstract

Abstract Backgammon game board for the simultaneous play of four players. The game board is divided by transverse and longitudinal line to provide eight boards, each board including six points, said boards being symmetrically disposed about a central playing area. The central playing area contains selectively eight, 10 or 12 playing points through which each player must move his playing pieces from his two outer boards to his two inner boards. The eight boards contain 48 playing points which may be color coded in a manner corresponding to the color coding of the playing pieces so as to identify the flow of each player's playing pieces.
