GHSudoku

GHSudoku 1.0 is a simple, easy to use, open-source Sudoku program by Glenn Hartmann Industries. Generates completely random puzzles in seconds for unique experience every time. Includes answer-check and puzzle solver.

Version 1.2 adds the ability to solve puzzles not generated by the program (this is a work in progress and is currently very slow, but eventually will yield the correct result). Also new to v1.2 is the ability to select the desired level of difficulty.
