This program can solve only easy SuDoKu puzzles by my usual method. For advanced solver go to www.sudoku.com Just enter the puzzle numbers from the question and click Solve (blank is 0). If you don't know what SuDoKu is go to Sudoku.com. This program has only one test question and is meant mainly for solving the puzzle you get from other sources (newspaper, websites,...).
