From reading the initial instructions it looked like the mystery will be more in the arrangement of the HSTs. At least that's what I'm banking on. We have a special church service that day so I won't get home until after lunch, and by then at least 3 clues will be up. I'll be able to see the direction she's taking and if it won't work for these size blocks I can always make up a simple design myself.
Is anyone else doing the Game Day mystery? If not I'll start posting on the Various thread.
