★★★★★
(Updated review from 1 star) An ad plays only when you end a game. The UI is great and intuitive. There are several customization options for your personal preference. I've tried the other free sudoku apps, and this is the best one.
★★★★★
Works seamlessly, including its biggest feature, which is cooperative sudoku solving.
★★★★★
Stable co-op with ability to restore connection after pauses.
★★★★★
Works great but could you allow more than 2 players to play. A group of 3 maybe...
★★☆☆☆
UI is slow. Actions that could take a single button press requires 3 or more. Seriously, who decided you need to highlight a square, select a number, then highlight a different square entirely before switching numbers else you change the first square. Absolute worst
★★☆☆☆
Crashes on start, and then I get a message saying it has a bug and that I should update as soon as the developer fixes it. Please fix the bug! This is the only app I've found to do cooperative sudoku that is also on Android and iPhone. July update: thought I'd try again, and it still crashes a second or two after I start it. Sad face. I really hope the developers fix this!
