Mathmom herself wrote a wonderful post for the carnival, which I was glad to see. I’ve missed her!

  1. Yes, I got it, though I lost track of the clues on my first time through. And then on my second try, I was sure there were two valid answers. But then I re-read the “fine print” about column 2 at the bottom of the page…

  2. I finally peeked at the answer. I had made a wrong assumption. On the bottom left to top right diagonal, I thought the middle two numbers had to be the same. They didn’t. Otherwise, I had it pretty much right. Good puzzle. I want to ask him if I can use it in the book. :^)
