VOLUMETRIC LOGIC PUZZLE Russian patent published in 1994 - IPC

FIELD: puzzles. SUBSTANCE: puzzle is made in the form of a three-dimensional body which has a spherical support with axles which, in turn, have profile guides with stops on the ends, the guides are mounted on the axles. Moreover, the puzzle has guide spherical segments with a shaped hole in the center which are limited by five adjacent circles, playing members in the form of triangles, pentagons and hexagons forming twelve pentagonal and twenty hexagonal sides on the surface of the spherical segments. In one case depending on the aim of the puzzle arrows are applied on a uniformly painted surface of a polyhedron along some of its ribs, the arrows form a closed broken line on the surface. The puzzle may be sophisticated by painting the pentagonal and adjacent triangular playing members of various sides (from one to twelve) of the polyhedron in various colors. In another case twelve pentagonal sides and adjacent one third of the hexagonal playing members on the surface of the polyhedron are painted in twelve colors and zodiac signs are applied on them. EFFECT: improved structure. 8 cl, 4 dwg
