Patent ID: 7108263

Claim:
A three-dimensional logic puzzle game made in the form of a sphere comprising game-playing elements of two types formed by dissection of the sphere by three planes perpendicular to the vertical axis thereof, and connecting elements, each of them connecting two adjacent game-playing elements of the same type, wherein the game-playing elements are formed by additional dissection of the sphere by three planes perpendicular to its one horizontal axis and by three planes perpendicular to its other horizontal axis perpendicular to the first one, three planes dissecting the sphere being center planes and six planes cutting off six osculating spherical segments having the same geometrical dimensions, wherein the game-playing elements of the first type are limited by two rectangular and one convex arc-like sides provided with shaped grooves made therein, while the game-playing elements of the second type are limited by three concave arc-like sides provided with projections made to fit the shaped grooves made in the convex arc-like sides of the game-playing elements of the first type.
