PUZZLE GAME Russian patent published in 1995 - IPC

FIELD: development of logical thinking. SUBSTANCE: puzzle game comprises a hollow transparent casing, a partition, and playing pieces. The partition is rigidly secured in casing and divides it into playing spaces. Disposed in the center of the partition is a playing channel with a through hole. The hollow casing has the shape of a ball or ellipsoid of revolution while the partition is shaped like a body of revolution with a concave surface on the periphery and a convex surface in the middle. The diameters of inlet holes diminish gradually from the inlet to where they merge into the playing channel. For example, the playing channel together with the inlet hole may have the shape of a paraboloid of revolution. The essence of the game consists in the speediest movement of playing pieces from one playing cavity to the other, for example from the upper cavity into the lower one and vice versa. This should be done by one method agreed upon in advance, out of nine described methods. EFFECT: improved design and higher entertaining capacity. 1 dwg
