Now with GUI! jiSudokuSolver is really a JavaSudoku master. It solves any puzzle, good or bad, even an empty one, usually in an instant, and it shows you how, every step. It also lets you play, generate, fix, test, reduce... just run startGUI.bat.
Do you have a Sudoku to solve? Or want to verify your solution? JSudokuSolver can do this for you! In contrast to other Sudoku solving tools, this program does so by using the same rules a human would. So you can improve your Sudoku solving skills.
This simplesudodu program is intend for studying in the sudoku solution algorithm rather than a game (If you want to make it a game, it's OK ^_^). Later I will implement the 4*4 or other kinds. Different sudoku requires different algorithm to solve.
