Advertise much? Also, difficulty? – Sudoku.com - Number Games Review

I love the puzzles this app offers, but with as many ads as there are to click through, I almost would rather pay for the app. All of the ads are SO ANNOYING. However I saw another review where someone praised the fact that there aren’t many ads. Is there something I’m missing? Also, you can’t see the difficulty level of the puzzle you are working while you are in the puzzle. Not a huge deal, but it would be nice to see while working the Daily Challenges where you don’t choose the difficulty.
