Download or Upgrade

To upgrade from an earlier version, simply download and run the setup kit. Your existing registration key will still be valid, and you do not need to uninstall the previous version first. (If you do choose to uninstall a previous version, first make a note of your registration details from the About box (Help -> About) as you'll need this after you re-install.)

What People Say

Love your program! I work Easy on Saturday, Sunday, and Monday; Moderate on Tuesday, Wednesday, and Thursday, and Hard on Friday. And when I'm having difficulty with other Sudoku puzzles, it's great to be able to input it into Sadman to see what's what.
