BUILDING SUDOKU PUZZLES

The Magnum Opus SUDOKU function allows you to make puzzles having degrees of difficulty ranging from 1 to 10. If you choose to make a puzzle having a high difficulty level, you need to be aware that, just as it takes longer to solve a hard puzzle, so also does it take longer to build such a puzzle. Please be patient...it will be worth it. The symbols in the puzzle are the digits 1 to 9 by default, but you can change this to any set of printable characters you like.

Simply move the cursor cell around the puzzle, and type the required values into the appropriate cells. Selecting the Test Puzzle Validity option will check the validity of the puzzle. If it has a unique solution, it will be saved, and you will be advised of this. If not, you will receive a message that the puzzle is not valid.
