A game which can be played by two or more players wherein each player receives an individual game set having a storage box containing three groups of building blocks, the blocks of each group being of the same configuration. The cover of the storage box serves as the gameboard for that player, and includes receptacles for holding one face of a regular pyramid structure having a square base. The building blocks are assembled on the gameboard to form the pyramid structure on the gameboard. The blocks of a first group are in a particular shape whereby, when positioned on the gameboard they each produce a four faced regular pyramid extending upwardly from the gameboard. The blocks of the second group are in the shape of a symmetrical octahedron having a bifurcated lateral edge defining a pair of angularly oriented faces that extend toward the central vertex. The blocks of the third group are in the shape of a four faced oblique pyramid having a parallelogram base. The building blocks within each storage box are distinguishingly identified from the other building blocks in other storage boxes.
A game for a plurality of players, comprising a gameboard for each player, each gameboard including receptacle means for receiving one face of a polyhedron structure, a set of building blocks for each player, the blocks interfitting to form said polyhedron structure on the gameboard, said polyhedron structure being a regular pyramid having a square base, the base of said pyramid fitting into the gameboard and being retained in said receptacle means, each set of said building blocks comprising three groups of geometrically shaped blocks, which groups of blocks symmetrically interfit to form said regular pyramid, and wherein each block of said first group of blocks has a shape whereby when positioned in said receptable means a four faced regular pyramid extends upwardly from said gameboard for each block;
