Great way to learn. This app has a great user interface that allows easy and fast entries. I also love how the hints show you how to solve it, not just what the answer should be. It has taught me how to solve the more difficult puzzles on my own.
One of the best computer Sudoku ever I've been installing the free version & finally decided to pay for this. Nice penciling, nice difficulty levels, cheaper than a magazine or Will Short book. Highly recommend. Try the free version for a test drive. Also doesn't rely on Google Play services (battery issues there)
It has got more difficult I play at the Annoying level and I'm convinced the puzzles have got more difficult recently. My average time to complete over hundreds of games has gone from around 3:20 to 4:00 and I don't think it's my brain that's deteriorating!
Fantastic App By far and away, the best sudoku app in the store. It has given me hours of pleasure and made commuting far less unpleasant. My thanks to the developer.
It's broken This was a great game, now it isn't working correctly. I uninstalled it and downloaded a new version. It still doesn't work correctly.
This is my favorite little puzzle app. Best Sudoku game available, worth every penny. I have it on my phone and tablet, whenever I upgrade, it's one of the first things I download.
Includes several small improvements to the tutorials, a fix for the Game and Hint menus occasionally appearing off-screen, and other minor bug fixes.
