What sudoku should be

Sudoku is simple to play but challenging. That's why this is my favorite sudoku app. It lets me focus on the game without distractions. The puzzles are challenging but not impossible (at least on Level 1). I highly recommend this app.

Fun but unforgiving

I really enjoy this game. The puzzles are great, I love the little sounds. However, the tap targets are unforgiving. Almost every game I make a "mistake" because I tap one number and another gets filled, both on iPhone and iPad. Very frustrating.

Beautiful, but lacks an undo

Really slick and polished interface, but as others have noted there is no undo. If you tap the wrong number (not a note) into a square, then all your notes get wiped out.
