ABSTRACT:
A three dimensional, educational and entertainment toy or game is disclosed. The game includes a board having a plurality of rows of pegs of preferrably hexagonal cross-section projecting from the top surface thereof and arranged with the pegs of alternate rows being offset from each other so that pegs in one row are disposed on a line halfway between those of the next adjacent row. Thus a line drawn from the midpoint of any three immediately adjacent pegs will form an equilateral triangle where two of the pegs lie in one row and the remaining peg lies on a line splitting the distance between the first two. The game also includes a plurality of geometrically shaped playing pieces taking various planar forms such as equilateral triangles, regular hexagonals, squares, circles etc. and being cast in varying colors so that an almost infinite variety of geometric and color configurations can be achieved when the pieces are assembled on the board. Each of the geometrically shaped playing pieces also includes a centrally located recess in its bottom surface and a centrally located projection in its top surface with the projections having cross-sectional configurations complemental to that of the pegs and being sized so as to fit easily into the recesses and with the recesses also being sized so as to fit easily over the pegs on the board.
