I solved an "annoying" puzzle today and am surprised that the rectangle marked in red is there.
This sudoku puzzle has two solutions which should not be possible. Or?
Where am I thinking wrong?

R34C12 meets most of the criteri for being a deadly rectangle, however R4C12 are both clues, which prevents this from forming a deadly pattern. As you are not allowed to change clues, the digits can not be swapped.

Of course!
Thank you!!!
I realize that now since you pointed it out.
I am fairly new to sudoku and love your app where I learn so much. And I am even happier now when I found this forum.
Once again Thank you so much!
