Great Sudoku App...
But the clock does sometimes get messed up while you're playing. Other than that, this is my favorite Sudoku app.
The puzzles are very challenging but you should not need to guess and check to solve any of them.
They are supposed to be hard to solve. If you have a hard time on the expert level of the free version, this may be a bit too hard for you. I recommend trying difficulties on the free app before you buy this one. You may be better off getting the paid version with all 4 difficulties.
Starts then Quits after 14.2 Update
Just updated to IOS 14.2 and this App now shows the opening screen and then immediately quits and the screen goes blank. App does not show running I the background.
Deleted and reinstalled and I’m up and running again. Good support page on developers site. Thank you.
Fun little game
I have seen past reviews claiming that the puzzles were not solvable without guessing. These are all solvable!
