Regular rhombic dodecahedrons having faces with two aspects of two different kinds, each belonging to a same family, one by a bare surface, the other one by a shaded surface, are piled on a base having nests allowing those polyhedrons to be placed on top to build a composed pyramid. The general configuration of the visible faces of one kind and of the other kind will respond to specific rules of the game.
