Sudoku solver with a simple GUI
There is no setup.
This will give you a blank sudoku board where you can place preset numbers. Click 'Solve' at the bottom and wait... As soon as all solutions have been found (if you use a Sudoku posed within a magazine or so there should only be ONE ) the board will be filled with the first solution and the 'Solve' button will turn into a 'Next solution' button. Clicking it will present you another solution if one is available.
