Habe die so nun gelöscht … ### 4/5 — Not as hard as I thought it would be *2017-05-02* The only thing I think it needs is, to tell me when I have finished with a particular number, as in, filled in all nine spots with number two. ### 5/5 — Sudoku *2017-01-05* Love this game. Hints teach you to learn the game. ### 4/5 — The new update is not great *2016-05-25* Overall I really enjoy this app but with the new update I have found that if I save a game while still playing and turn off the phone, when I come back to it, the data is lost. This was not the case previously. ### 5/5 — Beste kostenlose Sudoku-App momentan *2013-02-17* Die Werbung ist mir egal, weils kostenlos ist. Die Sudokus sind eindeutig lösbar, Funktionalität super, viele Sudokus in verschiedenen Schwierigkeiten. Vielleicht gibts bessere, habe bisher aber noch keine gefunden.... ### 1/5 — Too many ads *2012-11-11* Constantly changing ads on the screen annoyed me to the point that I deleted this app. Putting tape on the top of the screen would do, but then I could not even work with the useful apps ... :-( ### 5/5 — Sudoku HD+ *2011-12-10* Absolutely a great addictive game. I have tried many sudoku games and this is by far the best! Four levels of difficulty, hundreds of games in each level. And it's FREE!!!!!!! ## Frequently asked questions about Sudoku HD+ ### How many Sudoku puzzles does Sudoku HD+ offer?
