PseudoQ is a Su Doku puzzles on your computer.
PseudoQ is a java application for creating, playing and solving Su Doku (a.k.a. number place) puzzles of various types. It features both GUI and command-line operation. The automatic solving of puzzles uses "smart" techniques rather than a brute force search of every possible combination.
PseudoQ was originally intended as an entry for a competition in Linux Format magazine, but due to various factors wasnt ready in time for their deadline. However, it was complete enough that it seemed a shame not to finish it, and maybe raise some money for charity from my efforts.
PseudoQ is freely distributable under an open source license (LGPL). You are free to copy it, install it on as many machines as you like, give copies away to all your friends, etc. If you like it, however, perhaps you would consider making a donation? My job pays well enough that I dont need to make any money selling PseudoQ, so every penny I receive from PseudoQ will go to charity.
