Anglais - This is an excellent introduction to the concept of the Perplexus range. The difficulty of the spirals (make as many loops as possible!) is flexible because the course is double-sided. Take it anywhere, play it all the time, this mini 3D maze is perfect for discovering the world of Perplexus!
