Phlipple is a unique puzzle game. The goal of every level is to reduce a 3D shape to a single square. Elimination of squares is done by flipping edges around just like in a cardboard box. It starts off relatively easy to teach the basics, and provides hours of brain tickling fun. It's a great way to train memory as well as orientation in 3D.
