Incredible app. Never crashes. Smooth. Easy to use and understand. Different difficulty levels. Different backgrounds. Unobtrusive ads. You can fill in the little pencil marks manually or let the app do it for you. You can even put in your own sudoku problem and let the app solve it! Truly truly amazing app with lots of settings as well.
Great app Loved the free version so I bought it. Love supporting people who make good stuff. Love that it has different difficulties and that I can chose with each game. The settings give me a choice of how I want to use the buttons.
Best one found, grea t app but a sound with toggle on/off would be better
Fantastic game Very challenging, and if I just feel like having a relaxing fun game I can play at a lower difficulty level. Very adictive!!!!
Great Game Has everything I wanted in a sudoku game. Is very easy to play. I bought the pro version.
Challenging Had the free version and having found the extreme game challenging bought the pro version.
