CSudoku is a command line Sudoku solving program. It solves the popular 9x9 versions of Sudoku using Donald Knuth's Dancing Links algorithm. It was created as a fun exercise in computer programming and not necessarily to be a program useful to anyone in particular. There are many other Sudoku solving programs that are more refined and have many more features than this program would ever dream of having.

Sepp is a version of the classic sliding puzzle game in which the properly ordered tiles form a picture. The picture is user-selectable, as is the tile-grid geometry. Additionally, Sepp implements an innovative kind of player aggravation: based on a user-configurable degree of evil, it decides, during each animation frame, whether it will disturb a tile while the game is in progress. Sepp is written for the DrScheme enviroment, which is available for all major platforms.
PseudoQ is an application for creating, playing, and solving SuDoku puzzles of various types. It features both a GUI and command-line operation. The automatic solving of puzzles uses "smart" techniques rather than a brute force search of every possibility, mimicking the way a person would do it.
