See Puzzle 2 for instructions. Yes, the regions here are not square; that doesn't change a thing.
I wasn't planning on this: when I read about the new tagging functionality, I quickly went back and tagged all my puzzles as such, so that I and others can have a link that displays only them. I also wanted to throw together another puzzle to celebrate. Looking back, I saw that I've only done one of these so far, and given how popular they are the world over at the moment, I figured I'd make one of these. This is my first experiment with non-rectangular regions, and it was quite enjoyable. Comment about the puzzle here; email me the solution if you find it. - ZM
