A free (GPL) program that generates, solves, and gives you meaningful hints on Sudoku puzzles. It can generate books of puzzles to take on the road with you, and it can generate puzzles larger (and smaller) than the standard 9 by 9.
The preferences allow you to select your own color scheme, and to determine what techniques may be required to solve a puzzle it generates.
What's new in this version:
Version 0.2.3 is compiled as a universal binary, so it should run on intel Macs, but I have not been able to verify that, yet. Follow the link and
