This app has challenging and engaging puzzles that will force you to think outside of the box. Unfortunately, I'm not talking about the sudoku because the challenges that this app truly excels at are mostly about navigating aggressive ads. I understand that free apps rely on ads to generate revenue, but developers that justify annoying tactics, like ads that you cannot click out of, even after the ad has completed, are missing the point. The sudoku is ok. The ads are unacceptable.

Good Sudoku app. One short ad to start a puzzle seems fine. The ***big problem*** is that the ad generation starts to have issues after a period of time. Ads will no longer load, and the puzzle can't be played if the ad didn't load. In fact, no puzzle can be played. This has happened to me one before, and I had to clear my app data (cache wasn't sufficient) to get the app working, but my progress was removed. Now the app is unplayable again and I think I may have to move on from it.

Best sudoku app. Hands down. I have tried a lot of them, and for a long time, I thought for high quality puzzles in a high quality app I'd have to stick to Studio Goya and their limited number of puzzles. Then I found this and fell in love. The only thing I wish it had, was a way to select a color highlighter color, and just highlight/remove highlight by tapping the cell, instead of having to select each cell and then select each color individually.
