I did this as a mystery puzzle. At first I thought it was a circuit board. It took while for me to get that idea out of my head. That slowed me down a lot. These chocolates look so good.
Wow..you were brave to do it in the mystery format! I can see how you might think it was a circuit board. I would have thought the same thing. Not an easy puzzle, but I got through it.
I didn't find this one very hard at all. At least each piece was different, which made it easier. I made them on the side and then just slipped them into place. Thanks for a great puzzles.
