Puzzle Cube (871011)

This puzzle cube is made of rubberwood. Its demension is 6.7X6.7X6.7cm and each prodct is packaged in colour box. You don't have to be a rocket scientist to unravel this cube into a snake (just twist and swivel the 27 wooden cubes to uncoil the serpent) but it certainly helps to be a genius to put it back together. This legendarily difficult brain-teasing puzzle will have you undulating in no time. If the snake starts to constrict you, just remember: The string of cubes forms a Hamiltonian path through a 3× 3× 3 grid graph, duh! Skill and patience will be tried when turning the snake back into the original cube.
