Three dimensional rotating puzzle that opens
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.
