Satori Sudoku

Once game is complete, the onscreen buttons for the completion polio don't function forcing a restart of the app.

Being a sudoku lover I installed this app when I got my first iPhone over two years ago. I've installed 100's of games since, but this is the only one I still play on a daily basis; and I typically play it multiple times a day. 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.

Does not work with IOS 7.

This really is the best interface. I love not having a separate pencil/pen interface. I really wish there was an ipad version.
