The perfect gift for any puzzle fan, The Brainteaser Gold Edition includes Brainstring Original, CrossTeaser, and Planets puzzles for multi-level brain-fun. Brainstring is the famous clear cube with entangled strings inside that you move by interconnected, colored knobs on the outside of the cube. Can you solve it without making a knot? CrossTeaser is a square playing field where each cross features six colors that must be twisted until boxes of all the same color are on the same side. Planets is the most advanced of all three in this set - it presents sets of colored balls that only turn when properly aligned to adjacent balls, yet you must find a way to move them so only one color sets on each side.
Warning: Choking Hazard -Small Parts. Not for children under 3 years.
