Choerbaerts Suche nach dem Rönk (Choerbaerts search for the Rönk, or CSNDR for short) is the name of a 2d adventure. Its code is based on SDL and OpenGL. It is written in C++. At the moment, it is still under heavy development. There are playable releases available, but they are mainly for testing purposes without any story elements.
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.
