FIELD: puzzles. SUBSTANCE: device has three fixed game positions and mobile members which are fixed at one of these position and designed for alternate releasing and movement from position to position. In addition invention specifies device for checking correctness of relative position of mobile members in position and stopper system which prevents simultaneous movement of two and more members in case of violation of correctness of their relative position. Checking device has at least two commutator surfaces, which are punctured by mobile members and are connected to one another for relative parallel movement in single or several directions. Checking device has parallels and meridians which are designed as guides for sliding mobile members inside surfaces, which are respectively parallel and non-parallel to direction of possible movement of surface which contains them with respect to other surfaces. EFFECT: facilitated interest, increased significance of reached result. 9 cl, 8 dwg
