• 1. Get the tar archive from here.
  • 2. Untar and run "make". You need to have the gnome libs installed.
  • 3. Run "katsudoku". You are presented with an empty board full of numbers ;).
  • 4. Get a puzzle from your favourite newspaper. With a right-click you can set a number in a field.
  • 5. If you can exclude a number in a field, do a left-click.
  • 6. No undos! So be careful or you have to start again (like in the hardcopy version).
  • 7. Solve and enjoy!
