FIELD: games.
SUBSTANCE: invention relates to entertaining puzzles. Constructor puzzle, comprising at least two polyhedrons, on each edge of which a groove is made, which is a part of an imaginary cylinder recessed into the polyhedron, axis of rotation of this cylinder coincides with axis of face of polyhedron, on at least two edges of polyhedron in groove there is at least one ring, when the faces of the polyhedrons are combined, the rings form a hollow cylinder, wherein said rings are locked by locking rod arranged in hollow cylinder of rings. Outer diameter of connection rings coincides with that of cylinder that makes groove.
EFFECT: invention is intended for development of operational thinking: operational (active) memory and attention, namely development of a person’s ability to perform combinatorial operations with arbitrary elements in the head: to hold them in an internal (semantic) field, to combine them arbitrarily.
