The best soduko android app I've found so far - good user interface, and a sound knowledge of sudoku techniques. If you want to improve your sudoku skills this one is hard to beat. Update: nearly three years on and now the app is even better, with way more highlighting options and an improved interface. I don't understand the lower ratings because of ads - premium is the price of a paperback in exchange for practically unlimited entertainment.

Forced to watch an ad before I could even put a single number down. No thanks, I'll uninstall your app since ads are more important than playing.

Thank you for your review. We are aware that Ads are annoying and try to minimize their appearance as much as we can. Ads help us provide the app for free and support its continued development.

Best app to enjoy and get better at classic sudoku! each level runs a levelled path to slowly increase and face new patterns. The hint mechanism is quite smart and sometimes really helpful in understanding new strategies.
