Twelve elastic strings are moved around within a transparent cube.
Move the buttons from face to face to create various pre-defined patterns, without tying any knots. The inventor Guido Lap (from the Netherlands) conceived the idea for this puzzle already in 1992. The first version was presented in 2003 during the International Toy Fair in NÃ¼rnberg (Nuremberg), Germany.
