Abstract: A game playable by two opposing players consists of a playing board having two opposite playing sides and two sets of game pieces which occur in uniformly graduated lengths. The playing board is formed with two sets of slideways in which game pieces may be received and moved about. The two sets of slideways are arranged in uniformly spaced apart relation with the slideways of one set occurring at right angles to the second set so that the game pieces may be placed in slideways of either set and moved in two directions. Game pieces of each set of graduated lengths differ progressively one from another by a unit dimension corresponding to the width of a slideway. Differing combinations of game pieces selected by each opposing player in alternate moves may be arranged in the slideways in abutting relationship to one another and so as to extend from one playing side to the opposite playing side.
