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.

Mazeman is an original puzzle game, somewhat like "chip's challenge", except that it can generate new randomized puzzles from a carefully-balanced array of elements. The objective is to find the gems amongst the other dynamic maze elements. A very terse and powerful scripting language and an integrated script debugger enable users to generate their own maze designs. Scripts allow new players to acquire skills gently and provide diabolical puzzles for the expert.
