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!


Great Game

Sue Doku is easily the best Sudoku game on the iPhone app market. Beautiful, easy to use interface (especially love the simply use of color); actually challenging puzzles and a great note-taking interface. The absolutely only thing I could complain about is that I wish there were goals to work towards. As in, if you finish all the puzzles in level 1, then it unlocks the puzzles in level 2 and so on. Other than that, perfect.

Also, I'd like to extend a thank you for making the new levels free for those who previously bought the app! You guys are doing a great job!
