Awesome app

After many years of having this game it remains one of my very favorite apps, hands down! Simple in design and non-fussy, I never tire of it and always look forward to unwinding with this game.

Best sudoku game by far

Have tried most of the sudoku apps on iOS/Mac and usually gave up and went back to pen and paper because they all felt cumbersome to use or less natural. Then I tried this app and actually prefer it to pen and paper. Seriously the best sudoku app out there. Thank you dev!

Best version I have found

Efficient interface, stable, simple. I liked the free version so much (I believe one puzzle at each level per day) that I purchased the full version. I use it daily.

Warning! App takes your clipboard data!

It’s a great sudoku app but I feel it’s necessary to warn others. I haven’t had a problem with this app in my three years of use until now. A recent iOS update will tell you when an app pastes something from your clipboard. This app never accessed my clipboard until I recently copied my credit card number to pay an online bill. After paying the bill, I open Sudoku and almost immediately iOS notifies me that my clipboard has been “copied.” I don’t even know where it would copy to because there is no text box, but the result is the same: this app accessed my credit card info. Use at your own risk and NEVER copy personal info to your clipboard!!
