Difficulty levels are determined by techniques to master, not by number of givens.
Sudoku Uno includes a powerful solver. Unlike most Sudoku solvers, Sudoku Uno solely relies on human logic. It does not brute force the game to find a solution. Instead it applies that same techniques you would apply.

Sudoku Uno adapts to the way you like to play:
- Use green pencil notes to keep track of candidate values
- Or use red pencil notes to keep track of values you ruled out
- Optionally have Sudoku Uno help you with automatic pencil notes (*)
- Sudoku Uno can be set to block erroneous entries
(*) You are cheating only a little. The real thinking still needs to be done.
It is just more fun with automatic pencil notes. The boring bits are taken care of

Needs more work
Nice program but could be better. Perhaps double-clicking on cell that only has one possibility rather than force user to move mouse back to numbers on screen? Preferences to set some options like mistake mode? User settable font and size? Works fine on High Sierra 10.13.5 for me — Thanks...
WHat you need is to be able to change the boards colors and remove the posibilities, needs more control, too much going on, the game already makes you think much, we dont need to be deciphering out the app, blank white option w\o the possibilities and different style boards an or pieces, not like scrabble tiles, just numbers, w a checker, more like web sudoku,,, mahalo
