Excellent Sudoku app!
Thank you for updating it recently so that I’m able to use it again on the latest IOS!
Not worth the money
Great App For Sudoku Lovers
The ui isn't perfect, and it can be hard tapping the right squares, but given that sudoku requires a 9x9 grid, and the screen is only so big, it's hard to imagine how it could be done better.
The only suggestion I have is to support landscape mode. Display the board on the right and the number pad in the left -- my right thumb can select the square while my left thumb taps the digit.
There have been many times when I was sure I had a solution that didn't validate, or a puzzle which appeared to have multiple solutions. But after checking carefully I always found I was wrong. In the probably 1000+ games I've played, I haven't found a bug yet.
Well worth the 99 cents.
