Internetowa łamigłówka «Girl»

I think it is different. When there is a frame, it is immediately clear boundary fragments and it's very easy Assembly

This is not the first site where I am puzzling, the fact that the "frame easy Assembly" very much like many similar sites there is a function to display only the loop puzzles and many use it, here's a graph frame to prevent it?
This is my opinion and nothing more, I can not download the puzzles
