Excellent UI, made for a Sudoku player rather than the Oh-wow generation. The more difficult puzzles are up there with those of Paul Stephens. Only gripe I have is that I sometimes have trouble selecting squares along the top and right edges. However, I'll definitely be looking to buy the paid version.

Very cool app

Everything is great minus a small bug that incorrectly marks numbers as complete, and the graphics are a bit hokey.

Great App!!!!
