@alien
here is your corrected code

please mark your doubt as resolved and rate as well :slight_smile:

The only difference was I was using x<=sx+rn instead of x<sx+rn. Your code is particular to 3X3 suduko as you used the number 3 in isValid function. And in suduko function there is no need of using else after if as we are using return in every if statement. Right?
