The shape of the irregular pentagon and the angles defined at the apices are arranged so that the puzzle pieces may be placed on a planar supporting surface in side to side abuttment to cover fully the surface and in a variety of configurations and juxtapositions. Each apex in each of the puzzle pieces is provided with indicia of a value selected from M possible values. According to the preferred rules of the puzzle, the pieces are to be placed on the support in such a manner that each apex in a given group of adjacent apices carries the same indicia of value as the other apices in that group. The number of puzzle pieces is limited so that no two puzzle pieces have the same configurations of indicia of value. In one embodiment the puzzle includes thirty-two pieces and in a second embodiment, twenty pieces.
