Sudoku on app: what's the best one for mobile?

Most people I know use Sudoku.com or New York Times Crosswords (which includes sudoku), though honestly it depends a lot on whether ads bother you or you'd rather pay for a subscription. I tried several when I started looking for something to kill time on bike rides, and the truth is Sudoku.com has a pretty clean interface and the difficulty levels are pretty varied. If you care more about it being completely free without intrusive ads, you've got some open source options on the Play Store that work decently, though they usually lack polish in the design.

Are you looking for something without intrusive ads, or are you cool with advertising while playing for free?

I've been playing sudoku during my breaks at the pharmacy for years and I've tried quite a few. If what's getting to you is constantly closing popups, I'd recommend checking out **Sudoku - The Clean One** or **Sudoku.com** with the subscription (it's really cheap, I swear). But if you don't want to spend anything, there are apps that have ads under control and aren't so aggressive. The NYT has a good reputation, though the subscription costs you if you're already paying for other stuff of theirs.

Here's a trick nobody really mentions: the web versions of some apps work surprisingly well on mobile, and a lot of them save your progress to the cloud. If you go to Sudoku.com or similar ones through the browser, sometimes you don't even get as many ads as in the native app, plus you get a cleaner experience. Try that before downloading apps; maybe you'll save space on your phone and get rid of those annoying popups in one go.
