THREE-DIMENSIONAL TOY-PUZZLE Russian patent published in 2013 - IPC A63F9/08 A63B23/16 

FIELD: games.

SUBSTANCE: present invention relates to toys, namely, to mechanical three-dimensional toys-puzzles and can be used for playing, and also as simulator developing motility of hands, a souvenir or a device for training purposes. Three-dimensional toys-puzzles has a shape of rotary body on the surface of which symmetrically with respect to the axis of rotary body three closed grooves are formed intersecting at six locations, and in the closed grooves the movable elements are placed with the ability to move along one closed groove and from one of the closed grooves into another, the places of intersection of the closed grooves are on three half-planes, at that the places of intersection of each pair of three closed grooves are in one half-plane and the sections of the closed grooves located between them comprise an equal number of movable elements, and the remaining two sections of each closed groove located between places of intersection of closed grooves lying in adjacent half-planes comprise unequal number of movable elements.

EFFECT: enlargement of the game combinatorics, preventing jamming of movable elements and reducing the effort required for their displacing.
