Sudoku-Expert

The expert level is reasonably hard. I’m looking very very hard ones. But setting the notes is very tedious. Other apps allow to choose a number and then tap multiple squares. And why not a button to auto set all the notes anyway, complex puzzles always need them. Why make me put them there? Another annoying thing is you get 3 tries. But I never guess. I only create errors when I forget to turn the notes back on. There must be a way to prevent misuse of the app costing errors in the game. Otherwise, not a bad app. I’ll check back and see if it improves.
