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, differing in the game-playing elements being
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, the game-playing elements of the first type being
limited by two rectangular and one convex arc-like sides provided with
shaped grooves made therein.
