Sudoku.php is a Web-based program that tries to implement the same rules a human would use to solve a Sudoku puzzle. It can solve many Sudoku puzzles, but not all because it only uses logic and refrains from brute-force solving. You can interactively influence the solution process to try out rules of your own. You can easily enter a Sudoku puzzle and save it for repeated use.
