The three-dimensional game consists of a first row (10,30,50) of three rings and a parallel second row of two rings (20,40), connected to each other like the Olympic symbol. The rings are connected to each other in groups and/or individually, by apertures in one ring engaging into complementary apertures in another ring. The assembled rings have mainly parallel front and rear faces. Each ring has two or more, pref. an even number of apertures, with one aperture on the front and one on the back. Every ring in the second row has a slot (25,45) so that it can be expanded. The rings have the Olympic colors, and are of plastic.
