Perplexus is so addicting and challenging that no matter how hard you try you simply cannot ignore or stop playing with it. This maze ball, made of very tough and durable plastic, that had to survive several drops, is one of those challenges that you are sure you can beat, until it beats you! The colors and the shapes of the three maze tracks inside the ball are so eye catching that if you don’t play this alone, you can be assured you will attract attention. Your hand eye coordination will be put to the test along with your patience, your steadiness and your nerves. Brilliantly made, expertly executed, Perplexus delivers the goods. One parent noted that this would be good for a doctor’s waiting room…not if you already have high blood pressure!
