Just downloaded and love the look and the game play. I'd love it even more with a couple of enhancements. It would be great to be able to hide the clock. Too depressing and nervous-making ;-) And the option to hold the iPad horizontal would be good for those who have hand injuries. Much more comfortable. I know it would make play area smaller but worth it. Many thanks for a super game!

I bought this app because I like to play Sudoku and I wanted to support new developers like the one that created this app. Then I discovered that the app was going to a freemium model. No big deal. I bought the app up front, so I should be able to restore my purchase somehow. Nope!! No...wait!! It was just a bug. The developer should release a fix soon! Nope!! Still being asked for more money to play the levels I used to play before the app went freemium!! Really?! I'm sorry, but I'm moving on from this one!! App Deleted!!

Developer Response ,

We're very sorry you experienced this bug, LuckyPoorMan. When we went from a paid to freemium model, some users who hadn't updated the app in a while were prompted to pay for the full app. We created a fix for this so users like you wouldn't have to pay for the update, but we know it was still a hassle and we're sorry. We hope you'll consider re-installing Sudoku Sue and giving us another shot. If you have any issues, please click help within the app and we'll respond right away!

My new favorite Sudoku app

The guys who designed this app did a superb job. Elegant and functional, not gaudy like so many others, nothing to distract you when playing. This is the app I would have designed if I could design apps (can’t afford a Apple computer).

Great job guys!
