The invention relates to a pyramid construction game composed of a set of pieces having two different forms, that of a regular tetrahedron and that of a trirectangular tetrahedron, of a set of support plates hollowed out in the shape of a regular polygon, serving to hold the construction at its base, and of a box equipped with a lid completely filled by the tetrahedra and the support plates. The invention may principally be used as an educational game for young children. <IMAGE>
