Customer Reviews

Dramatic improvement with this latest update... but

I had complained, like so many others, about the previous update. I felt it was only fair to also write about the huge improvements that appeared in this most recent "fix." Huge difference. The game is actually fun to use again. Plus, and this may be my imagination, it even seems like the character recognition has been made more accurate.

My only request at this point, and this is because of my own selfish desire to improve my times, is to have a way to quickly change the temporary numbers into actual entries. So often I complete the game when using the little "possibles" as I call them. But the timer keeps ticking away until I go and replace all of them with actual written numbers. Having a one click conversion would be great, even if it then shows all of the errors that I might have missed!

Best sudoku!

I tried several sudoku apps before selecting this one. I like that the app allows you to "pencil in" numbers in boxes. You can have multiple numbers "penciled in" and then begin to delete them as it is clear which numbers should remain in which should not. I like the optional sound function and the option of selecting colors that correspond with each number which helps see visual patterns. And, the help function is great. When I needed some assistance and emailed a request I received a response back immediately That was very helpful. This is truly a great app


What response! Everything is fixed. Even things I had not thought of. This is my all time favorite. Thank you so very much.

I was happy before with the exception of character recognition. No pause. Please make the hard to read characters an option. The help is good. This is my favorite game. Please give back the old options. I like the new game select. Richard
