Sudoku Solver: Hint or Solve

Photo import is a horrible experience. You are supposed to drag dots to corners of the puzzle and much of the time the image it scans is sideways or upside down. After a lot of trial and error and wasted time you get it right side up. Then it guesses the numbers and gets almost every one wrong. I am importing a picture from another app and maybe it’s OCR model can’t deal with light colors on darker backgrounds? Anyway, you can tap to change incorrect number. But they’re almost all incorrect so that’s a lot of work. And if it guesses a number for a blank square? You literally cannot remove a number. Just change it. But it’s an unknown number so you don’t know what it is. I don’t know how this app passed review. It’s unusable.

I thought this app would allow me to load the numbers at the start of the puzzle and then provide all the options in all squares, not just one or all. I like to complete puzzles on paper and it would be helpful to have an app that will take away the time needed to fill out all possible solutions in the empty squares, so I can improve my solving skills.

Helps to be able to choose one square to solve instead of the whole puzzle being filled in. Sometimes one is all that is needed to move forward.
