Zaz is an arcade action puzzle game where the objective is to get rid of all incoming balls by rearranging their order. Currently it includes 20 different levels and two modes of gameplay. The engine allows for easy custom level creation with unlimited number of paths, different speeds, ball-sizes, and rules. A 3D accelerator is needed for decent gameplay.
Morris is an implementation of Nine Men's Morris that also supports several rule-variants and different board layouts (including Morabaraba). You can play against the computer, or play against another human opponent. The computer opponent learns from previous games and tries not to make the same mistake twice. This ensures continuous variation in game play, should you manage to beat the program. Furthermore, the program can give move hints and provides unlimited undo/redo.
