An improved design and an additional set of strings set this version apart from the original.
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. Compared with the original it still has 12 strings but this time in four colors distributed over four sets.
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 (and TwistyPuzzles.com forum member) Oskar van Deventer. It comes beautifully packaged in a thin clear plastic box.
