Abstract
Abstract A multiplicity of playing pieces capable of being assembled together in interlocking relation in accord with a predefined scheme, and a holder for supporting the playing pieces of a player preparatory to their being played. The multiplicity of the playing pieces all embody substantially the identical construction, differing solely from one another insofar as concerns the indicia appearing on one face thereof. The locking means each comprise a concave-shaped aperture and a convex-shaped projection formed in adjoining relation to each other along the edge on at least one of the sides of each of the playing pieces. Moreover, each of the concave-shaped apertures and each of the convex-shaped projections have the same radius of curvature so that the convex-shaped projection formed along the edge of the corresponding side of any of the playing pieces is receivable within the concave-shaped aperture formed along the edge of the corresponding side of any other one of the playing pieces. The holder consists of an upstanding member having at least one vertical side thereof formed so as to be inclined at a slight angle from the vertical and operable for supporting playing pieces of a player thereagainst in an upstanding position. In addition, the holder has formed thereon means consisting of a multiplicity of suitably spaced concave-shaped apertures cooperable with the convex-shaped projection of the locking means with which the playing pieces are provided for purposes of maintaining the playing pieces positioned in the aforedescribed manner on the holder.

Claim 1
Independent Claim
743 words
A game apparatus adapted to be played by a plurality of participating players comprising: a. a multiplicity of playing pieces assembable relative to each other in a predetermined manner, each of said multiplicity of playing pieces comprising a member having a first pair of sides of equal length extending parallel to each other and a second pair of sides of equal length extending parallel to each other and at right angles to each of said first pair of sides, each of said members having one face thereof divided into two sections, each of said two sections having indicia provided thereon matchable with the indicia appearing on at least one of said two sections of another one of said members, each of said members further including at least one locking means formed on each one of said first pair of sides and of said second pair of sides along the edge thereof, said locking means formed on any one of said first pair of sides and of said second pair of sides of any one of said members being cooperable with said locking means formed on any one of said first pair of sides and of said second pair of sides of any other one of said members for interlocking together any two of said members to maintain said any two of said members in assembled relation in any selected one of a plurality of positions relative to each other, said locking means each comprising a concave-shaped aperture and convex-shaped projection formed in adjoining relation to each other on each of said first pair of sides and on each of said second pair of sides of each of said members, each of said concave-shaped apertures and each of said convexshaped projections having the same radius of curvature so that said convex-shaped projections formed on any one of said first and second pairs of sides of any one of said members is receivable within said concave-shaped aperture formed on any one of said first and second pairs of sides of any other one of said members, said concave-shaped aperture formed on one of said first pair of sides of each of said members being positioned along the length of said one of said first pair of sides so as to be aligned with said convex-shaped projection formed on the other one of said first pair of sides of the corresponding one of said members and said concave-shaped aperture formed on one of said second pair of sides of said corresponding one of said members being positioned along the length of said one of said second pair of sides so as to be aligned with said convex-shaped projection formed on the other one of said second pair of sides of said corresponding one of said members, and said convex-shaped projection formed on said one of said first pair of sides of said corresponding one of said members being positioned along the length of said one of said first pair of sides so as to be aligned with said concaveshaped aperture formed on said other one of said first pair of sides of said corresponding one of said members and said convex-shaped projection formed on said one of said second pair of sides of said corresponding one of said members being positioned along the length of said one of said second pair of sides so as to be aligned with said concave-shaped aperture formed on said other one of said second pair of sides of said corresponding one of said members; and b. a holder comprising an upstanding support having one vertical surface thereof inclined at a slight angle from the vertical for supporting thereagainst a plurality of said multiplicity of playing pieces in an upstanding position, said holder including means formed thereon cooperable with said locking means formed on any one of said first and second pairs of sides of any one of said multiplicity of playing pieces for maintaining said plurality of said multiplicity of playing pieces in supported relation on said holder, said maintaining means comprising a plurality of concave-shaped apertures formed in equally spaced relation relative to each other on said holder, said plurality of concave-shaped apertures formed on said holder each having the same radius of curvature as said convex-shaped projection of said locking means formed on each of said members so as to be capable of receiving therewithin any one of said convexshaped projections formed on any one of said members.
