Snake cube

The snake cube is a mechanical puzzle, a chain of 27 or 64 cubelets, connected by an elastic band running through them. The cubelets can rotate freely. The aim of the puzzle is to arrange the chain in such a way that they will form a 3×3×3 or 4×4×4 cube.

Variations
Variant : from wooden cube to puzzle man.

A variation on the puzzle is a Kibble cube, which is also a string of cubes but has slots on the cubes. There are also many different styles of the cube. It can be made up of wood or plastic and can vary in colour, material and size.
