<p>A spherical logical puzzle is disclosed comprising four interconnected axis defining branches (including 402, 404, 406) to each of which a fixed puzzle segment (202, 204, 206) of arcuate triangular shape is connected, the segment being rotatable about the branch axis; a plurality of free puzzle segments are provided comprising six arcuate square puzzle segments, e.g. 104 and four arcuate triangular puzzle segment, e.g. 210 and the free and fixed puzzle segment are coupled together to form a sphere; the segments are capable of adopting a plurality of relative positions and are movable between said relative positions by rotation of some of the segments relative to others in planes perpendicular to said axes. The surfaces of logical puzzles can bear a representation in the form of a raised pattern. <IMAGE></p> |
