A three-dimensional solitaire game in the shape of a body having equal lateral surfaces, which is assembled by joining together part-bodies which are movable relative to one another, in a manner such that each lateral surface has a rotatable central piece, edge pieces and corner pieces and the part-bodies forming any desired lateral surface can be jointly twisted about the centre of the lateral surface, is, according to the invention, not in the conventional cube shape but in the shape of a regular body with lateral surfaces which are not at right angles to each other, especially in the shape of a regular dodecahedron or of a tetrahedron. As a result of the non-orthogonal relationship of the lateral surfaces and axes of rotation to each other and, in the case of the dodecahedron, as a result of the increased number of part-bodies, the difficulty of the solitaire game is increased in comparison to the known cube.
