Perplexus is the 3-D puzzle maze you can't put down! It may look like a transparent amusement park for marbles, but this self-contained puzzle ball is a challenging maze for most ages. The Perplexus Original Maze Game is an 20cm clear sphere filled with multicoloured pathways covering different areas of the sphere's interior. A small metal ball rolls around on the inside and it's your job to guide that ball through the maze to its end. Once the ball is balanced in its starting position, it's easy to start rolling it around the tracks. Perplexus is designed to flip, twist and spin the ball along the numbered paths-while you work with and against the forces of gravity. A super spiral, a tightrope and a swing arm to form 3 different puzzles and 100 challenging barriers to discover and overcome. This game is easy to play, but hard to master. This Perplexus Supreme Set also comes with Perplexus Rookie, a smaller and easier version of the original Perplexus. This 17cm toy features 75 barriers of varying difficulty and is sure to keep you entertained for hours! If your ball falls off the track, just try again. Because of the small pieces, both the original Perplexus and Perplexus Rookie are best for ages 6 and up. Once you have had enough brain strain for one day, the free mesh storage bag can help you easily store the items away until the next use!
