I have used this app every day for a year, at least 3 puzzles per day. It's my go-to for relaxing and I am not bored in the slightest. Some puzzles are frustrating, some are genuinely entertaining. the paid for version is absolutely with it. Literally the only thing I would ask to add would be more specific instructions for the hint system. it says what each rule violation is, and then gives generic instructions, but ideally you would have step by step exact information. Great app! well done!

It could be a great app, so much potential but... I understand ads but there's a point when they become unbearable. The ads make this app nearly unusable. You pause the game, watch an ad to return. You haven't seen an ad for 5 minutes, watch an ad. You figured out a digit, watch an ad. You solved a puzzle, watch an ad before you get your report screen. And the barrage of ads often say 'No annoying ads.'. Well not this app. This is more ads than game.

Thank you for your feedback! Ads allow us to provide puzzles for free. We try to keep them as non-intrusive as possible while supporting our team's work. If you prefer a completely uninterrupted experience, we do offer a Premium version. We hope you still enjoy the logic challenges!

Best Sudoku game on android. I've played a load of others and they don't compare. The settings help you mould the game to your preferences, loads of really fun extras that are easy to follow and understand, and the support team are ace! Super helpful. The ads aren't intrusive or long or annoying. Their premum option isn't overpriced, and it doesn't restrict the game without it at all. A really fun spin on a classic, can't put it down. Played it for hours, and there's still tons more!
