It's a great app! Though it would be nice if you could add a feature where you can see where you went wrong instead of just saying the puzzle is wrong? (Like putting the set definite numbers that are right and then numbers you added in a diffent colour or something)

The best solver, showing why. However, why does the entry require so many unnecessary clicks, from the user point of view? It doesn't seem to be that difficult: user friendly interface? Waiting for the update. Thank you.

Hi, the next version will change the graphics of the whole application, I will also work on a more user-friendly interface to solve this problem.

I love playing sudoku. It is my favorite game to play, so creating my own Sudoku puzzle with an idea that I have in my head is a lot of fun.
