After playing for some years content with the layout, back button, and variety of custom options, the game got updated again and again, and again. Everything that made the game enjoyable was reduced to a dull bland slow experience. The ads, absolutely horrible. Had to play in airplane mode. That helped with the ads but, all else is still garbage now. Uninstalling the game. Bye bye.

Excellent game. I love it. However it is constantly sending tracking data to Google and Facebook despite having the paid version. It is enough that it drains my battery cosiderably faster and constantly has my tracking blocker working. We are talking thousands of tracking attempts in a few hours. Really sad that paying for a game gives you this kind of invasion of privacy.

Still like it, but... Maddeningly slow animations. I'm much faster than the game UI. Prior: I returned you this after a long absence. I don't remember the ads being so obnoxious. If we "x" out of the ad, it shouldn't pop to a "Download?" screen, that we have to "X" again. Prior review: One of Sudoku apps I like the best. I especially like the Pencil and Paint implementations. I wish there was a way to get more contrast / visibility for the pencil marks, because: limited screen size.
