I came across this door on the west coast, and I thought I already understood all these puzzle elements, but I don't see any way it can be solved.
My understanding of the rules involved here are:
1. I must make the shapes for the yellow blocks. The one on the far right is rotatable, but the other is not.
2. The blue blocks subtract from the yellow blocks.
3. My path must go through every single black dot (so, in this case, every single intersection on the board).
I'm interested in the solution, obviously, but more so I'm interested in if I'm missing or misunderstanding some of the rules here.
