Brainstring by Recent Toys. This new puzzle will tie your brain in knots! Pull the rubber tips to work the colored strings through the open slots of the sphere. Creating a solid color on each side is easy, but 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! Invented by Guido Lap & Oskar van Deventer, published by Recent Toys
