Abstract
A spherical puzzle that consists of eight five-sided pieces and thirty six-sided pieces which are connected by means of a locking rail system that allows all of the pieces to be shiftable around the three equatorial planes of the puzzle. This allows various color patterns to be placed on the surface of the sphere which can be scrambled and then rearranged in predetermined patterns. Also, the puzzle is hollow and can be opened if the pieces are arranged in the correct order.
Claims5
A rotating puzzle device having pieces movable around three equatorial planes which are perpendicular to each other, the puzzle comprising:
- a. Thirty (30) six-sided pyramid shaped pieces, each having a circumferential groove in the four sides a set distance from the center of the puzzle, with its opposing sides angled approximately thirty degrees from parallel and each having the peak of the pyramid removed and,
- b. Eight (8) five-sided pyramid shaped pieces each having a circumferential rail on its three sides a set distance from the center of the puzzle, each being equiangular with the angles set at approximately sixty degrees and having the peak of the pyramid removed,
- wherein said six-sided and five-sided pieces are connected to each by a locking rail system which allows them to be removable around all three equatorial planes and change relation to each other, and three of the five-sided pyramid shaped pieces have one corner of the rail system removed, one of the six-sided pyramid shaped pieces has one inner corner section removed, and one five-sided pyramid shaped pieces having one corner of the rail system that is removable.
