Edit: Used for years, update broke it. Animations glitch, ads go straight to game instead of waiting for you to get ready, and some ads go minutes before giving click to next buttons. Old: Option to use number-first typing, although I wish you could just tap numbers to select that. Options to auto clear obvious notes or fill obvious squares for speed. Educational hints if you want them. Bells and whistles if you want them. Levels done fairly well. Hardly anything more to want.

Game itself is great, but every time I finish a puzzle and start a new one I'm thrown into an unstoppable game ad. I don't mean a timed ad that ends - I mean a full screen video game ad that I can't get out of without force closing this Sudoku app. I shouldn't have to force close and reopen an app 5+ times just to start a new puzzle.

This WAS my favorite soduku game for years. The last few months this game is unplayable now due to ads. Launch game, forced to watch an ad, no way to skip it. Clicking on ad doesn't remove it. there is no way to get past the ads. It's no longer a game. It's an ad viewer. Uninstalling.
