<p>The tridimensional logical puzzle comprises a support, which is fabricated as a tridimensional cross-piece (1), central elements (2), rib elements (6) and angular elements (9), which elements are so mounted that they may interact therebetween. The central elements are arranged on the ends of the cross-piece so that they may be turned. At least each of the rib elements (6) is comprised of an outer portion (8) and two inner portions (5) so that the inner portions of the rib elements, provided on each face, form together with the central element of said face a cylinder (7), which cylinder and the outer portions of the rib elements are so arranged that may be mutually turned. </p> |
