Sudoku Players' Forum (clone)

Hi, guys I want to share the sudoku site I find recently https://sudokupro.app/. It really has a friendly interface which I was looking for for a while. Also, I found out that it can be played as offline as online.

Perfect ?? Annoying !! The expert puzzle i tried has multiple solutions !
9...72..3.56.18..773..........94657.....8.9...9...5.........7.....7.......3.2..4.

One red flag is that the app store images are just images and they dont link to app pages.
So I'm guessing the sudoku app was 'borrowed' for the purpose of monetising the web page!
Avoid.
