Good app, easy puzzles – Sudoku (Full Version) Review

The app is designed fairly well. The utility of the auto-pencil is nice, as well as blue highlighting the numbers. One problem I have is that the "extreme puzzle" is really quite easy. Maybe toss in a few harder extreme puzzles. 4 out of 5 - 5 out of 5 when more challenging puzzles are added.
