A puzzle (20) is disclosed, comprising twelve spanning ribs (24), eight body members (22), six caps (26) and a rotational means (50). The ribs (24) define a central locus (X) and six subordinate locii (Y) equally circumferrentially-spaced thereabout. The subordinate locii (Y) define three normal axes (A) intersecting said central locus (X), each of said subordinate locii (Y) being intersected by a respective axis (X). When the ribs (24) are operatively configured, a respective four ribs (24) extend from each of said subordinate locii (Y) to the subordinate locii (Y) adjacent thereto, each body member (22) is surrounded by a respective three ribs (24), each cap (26) is positioned at a respective one of the subordinate locii (Y) and the rotational means (50) enables selective rotation of a selected group of four ribs (24) extending from a selected subordinate locii (Y) about the respective axis (A) intersecting same. A locking means (76) for exclusively enabling rotation, when said selected group has undergone said rotation otherwise than to the operative configuration, of said selected group. |
