LOGICAL TOY

A logical game, in which discs (3) which can be rotated relative to one another, are arranged coaxially relative to one another. In order to provide a logical game which allows the compilation of exceptionally diverse and ever new variations with a very low number of elements, cannot be dismantled during the game, and the degree of difficulty of which can be set at will, provision is made for the discs (3) to be arranged on top of one another or inside one another so as to be non-displaceable or limitedly displaceable in the direction of their geometric axis and for at least part of its outer surface to form a game surface (4), on which there are formed groove elements (8), having a centre-line which is advantageously parallel to the game surface and a cross-section which is advantageously congruent, or grooves (5) which are compiled from said groove elements (8), rollable or displaceable symbol bodies (6), which are guided in the direction of the centre-line of the grooves (5), being arranged in the grooves (5).
