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. While all commercially available 3×3×3 cubes appear to be identical in terms of the sequence of straight and bent connections, and have only one solution (up to symmetry), at least two different 4×4×4 cubes are sold, both having four unique solutions.
The objective of the puzzle is to organize the chain into a 3×3×3 or 4×4×4 cube. All commercially available 3×3×3 cubes have the same sequence of straight and bent connections with only one solution (considering symmetry), while at least two distinct 4×4×4 cubes are sold, each having four unique solutions.
