<p>The puzzle comprises a plurality of layers 36-43, each of these layers being rotatable about a first, central axis 47 relative to the other layers. At least some of the layers other than a central layer each comprise a plurality of pieces arranged around said central axis, and the central layer is formed from two interlocking halves 10, 12 which are rotatable relative to each other about a second axis extending perpendicular to said first axis. All the pieces to one side of a diametral dividing line can be rotated together relative to the pieces of the other half about said second axis. <IMAGE></p> |
