Before you give the command to build the Sudoku puzzle, you can set some options which the program will use during the
construction process.
Symbol Set: Enter the set of symbols which you want to appear in the completed puzzle. Make sure you enter exactly 9 symbols
which may include any printable character.
Difficulty: Select the difficulty level to be used for your puzzle. There are 10 levels of difficulty available.
If you want to make a number of puzzles all having the same dimensions, then type a number into the How many
puzzles input field. When you issue the Make command, Magnum Opus will make that number of puzzles. The puzzle names will be a number which starts
with the number which you provide for the first puzzle, and increases by one for each new puzzle. The companion Sudoku Java Applet is able to perform a
calculation based on the current date, and the start date for the puzzle sequence, to produce the name of the puzzle file to be loaded. This makes the setup
of Daily Puzzles a very simple task. Virtually any number of puzzles can be made in a single operation using this feature.
If you do choose to make multiple puzzles, then by default, Magnum Opus will change the difficulty of the resulting puzzles over a cycle
of seven puzzles. This would be useful for a daily newspaper so that the week could start with a very easy puzzle, with quite difficult puzzles reserved
for the weekend. If you don't want this feature, clearing the Vary Difficulty on 7 day cycle checkbox will disable it.
