Building on the success of the top-selling puzzle, this advanced version adds more sides, colored strings and easy-to-grasp rubber tips. More challenging than the original, Brainstring Advanced will stretch your puzzle-solving skills to the next level. Pull the rubber tips to slide the colored strings through the open slots of the sphere. Creating a solid color on each side is a small task - the real challenge is untangling the knot in the middle. Make the puzzle easier or harder based on how much you tangle it up. Stretch your imagination to find the solution! Ages 6-99.
