Sudoku 778 can be solved in two ways. I don't know if you see this as a correct sudoku, so I just post it here. The in the picture highlighted 8, and the 4 next to it can be swapped, when the 8 and the 4 in the lower right block are swapped too.

This sudoku is Diagonal variant - it means also both diagonals must have unique values. If you swap 8 and 4 , you will break diagonal constraint.

I know, this should be better explained on puzzle page. We are working on detail documentation for puzzle types.

No, it doesn't need any explanation (although that would indeed be better for beginners, but not for me), I was just blind :oops:

Thanks for the response!
