Great app Does exactly what it says on the tin. Only found one thing missing, really - the input data needs to be retained so that it doesn't need to be re-entered from scratch if the solution reveals an error in the input data. The 'camera' input suggestion is also an excellent idea for smartphone users.

Amazing My brother biren was not able to solve this soduka. So, I insisted him to download this app. Now, he has became genius. Now he can solve any soduka challenge put forth before him.

Great I can use this to solve sudoku puzzles within minutes. The only issue is that I play traditional Japanese sudoku which is in 6×6 patterns. Please add 6×6 patterns and will rate 5 stars. Thx

Does exactly what is says on the tin Excellent app and easy to use. Came in useful when out in the middle of nowhere doing sodoku based geocaching puzzles.

No 'possibles' function I'd like to be able to input the respective missing possible digits in each cell, enabling me to scan them for uniques, pairs, triples. My memory can't hold the possibles otherwise. Esp for stinkers I can't solve on paper.

Just about the ideal app. This does exactly what it says, quickly and efficiently. It doesn't demand massively inappropriate permissions, doesn't hog resources, doesn't interrupt your game play with ads. As others have said before me, moving to your memory card would be a great addition (but you know what you're getting before you install), and yes you could add a camera function, but come on, you can't take 30 seconds to enter the numbers by hand?
