Brainstring Advanced (Cardboard Box)

The Brainstring Advanced adds a fourth set of strings to an already complicated puzzle. Built on a truncated octahedron body, this version is not only more complicated, it is also more colourful, and in my opinion, more attractive. Move the buttons from face to face to create various pre-defined patterns, without tying any knots. The Brainstring Advanced was developed in close co-operation with master puzzle inventor Oskar van Deventer. It comes in a cardboard box. Also see the Brainstring and the Brainstring 'R'.
