Friday Puzzles #50
So writing a Yajilin puzzle with symmetry gives you all sorts of issues with uniqueness and stuff. Good luck to anyone in the hunt for a symmetric 10×10 with just the four givens! Still, I gave it – symmetry in general that is – my best shot with this one, and I only just failed. Enjoy!
