Non-intrusive ads, big range of difficulty levels

Uninstalled other killer sudoku apps because the ads made it a horrible experience. I hope they keep the ads as they are - a small banner at the bottom and short pop-ups after you finish. The range of difficulty is also good, though it is a big jump between medium and hard settings.
