User reviews

great game but suddenly broken

whenever i try to open the game now , it instantly crashes before even getting to the games splash screen. attempted reinstalling the game with no changes occurring.

The Best

In my opinion the is the best sudoku app out there. I wish the creators would update it because I canโ€™t get it on my iPhone which is newer than the iPad I play it on.

Canโ€™t add new puzzles with latest iOS update

I love this app, but it now kicks you out of the app when trying to add a new puzzle. This started happening after the latest iOS upgrade. I would have rated it 5 stars if not for this bug.

Sudoku X4U

I love this sudoku app. It not only has great graphics and interface but it also has jigsaw and X sudokus. Difficulty levels are from very easy to very hard but they all have a unique solution. No guessing necessary. My only problem has been that when prompted to write a review it canโ€™t access the App Store. By the way it comes with a small set of free samples but I could buy an unlimited number of sudokus for $2.99.
