My first attempt at doing Sudoku solver. There are quite a few program available, Most of them don't have assistant mode and ones who do, don't do it the way I'd like it to be done. So I finally coded my own solver and helper.
It's in C, and execuatable is for win32. I'd keep working on this code until I'm satisfied. If you want, you can try my program and can also look at the source code. Any suggestion/comment please drop a line at my project's website.
