So many hours of play. There are a few variants that I'm not a fan of, but that's just my preference and there are so many of the other variants that I've so far not run out. One of the updates made it super hard to continue playing the game, and I not only got a response from support very quickly, the visual bug was patched within a day or two. Absolutely worth getting this game if you like sudoku-style puzzles.

I've been loving this app for about two years now. Suddenly, I get an inescapable pop-up that says I have to watch an ad or buy premium, and the ad never loads. The bottom ad is working fine. I have no ad block and have always allowed ads on this app before. I wait for a day, hoping the issue will resolve itself. It doesn't. So I uninstall, and reinstall hoping to fix the issue. Every puzzle I've ever done is gone. Absolutely wiped. No stats, no progress, nothing. This is beyond disappointing.

Thank you for your review. Sorry about your ad experience! Issues like this are often due to Ad Blockers, VPNs, or ad settings. Ads help us keep the app free. Bottom banners aren't really ads. We don't store personal data therefore, deleting the app also removes all progress—reinstalling means you need to start fresh.

the ability to add/remove possible numbers in groups pretty much removes all tediousness from the game. and variations are just amazing, some variations combinations really makes you find completely different approaches. I don't want to play regular sudoku anymore. on top of that, if you are stuck, hints give very decent explanations and reasoning, which often help to solve other puzzles as well. advertisements are there, but are reasonable.
