摘要： A generally spherical three-dimensional puzzle includes first and second polar caps (14) disposed on opposite ends of a primary axis (A) of the puzzle. A plurality of base rings are stacked on the primary axis between the first and second polar caps. Each base ring is rotatable about the primary axis and relative to the other base rings and polar caps. The base rings and polar caps collectively share an infinite number of lines of longitude (L) passing through the polar caps. Additionally, the puzzle includes a plurality of slidable segments (20) disposed adjacent to external surfaces (22) of the base rings and polar caps. The plurality of slidable segments are slidable together along a common line of longitude of the puzzle when the base rings occupy a predetermined rotational state.
