<p>The game consists of a series of superimposed or concentric elements (2, 3, 3') which are movable relative to one another. Each element (2, 3, 3') carries complementary signs or parts of signs (5) intended to be combined together, by relative displacement of the abovementioned elements with respect to one another. At least one of the elements (2) is provided at its periphery with a ring (6) equipped with an annular groove (9, 9') intended to fasten each of the abovementioned elements (3, 3') such that the latter have an edge (11) enabling them to be handled separately. <IMAGE></p> |
