Great, but full of ads even if you pay?! I paid £7 (!!!) for the ad-free version (you'll see an ad every time you unlock your screen in the app, win, or lose) as it's a great app; however, I've since found even if you'd paid, ads remain if you run out of time. If you then don't finish the puzzle in the extra 60 seconds... You have to watch another 2-minute ad. This is pretty outrageous and I feel like I've been lied to by the devs. Despite the good sides, I wouldn't recommend for this reason.

Hi, sorry for any inconvenience. The Remove Ads is for removing the Banner Ads and the Pop-up Ads that appear before and after each puzzle. But Bonus Videos for using hints, advanced notes, or getting more chances could not be removed. :-( If anything else, please reach us at sudoku@fungame.studio. Thanks for your understanding! - Echo

By Jayel I have tried quite a few different Sudoku games and I think this is the best one and it's free! I like many aspects but sometimes I loose a game by selecting accidentally the wrong input number. I don't know how you can put more space between the adjacent numbers, other than perhaps in two rows. Also, I would like to delete my statistics, (I want to start afresh) but there isn't a facility for that. This is the one I would recommend. It is also suitable for beginners and expert.

Good gameplay, but the ads seem excessive and unnecessarily complicated. Ads will play automatically after each game ends, occasionally when starting a new game, and also when resuming after pausing. Most of the ads are "skippable" but "skipping" takes you to the play store. Then you have to return to the game and then finish the next part of the ad before being able to close it. It really says something about the game when most of the reviews talk about the ads....
