How do I submit the answer to a particular puzzle?
Just pop it into the subject header of an e-mail and send it off to email@example.com.
Can I submit more than one e-mail per day?
If you send in an answer that you later realize is wrong, feel free to send in a new e-mail with the correct answer. But please don't send multiple e-mails as a way to improve your chances. For one thing, it won't work.
What's the deadline to get you the answer to a puzzle?
Midnight (Eastern time) on the day it appears.
What if I miss a day or can't solve one of the puzzles? Will I still be able to solve the final puzzle and be eligible for the grand prize?
Probably. The final puzzle has been designed so you can miss one or two of the previous answers and still figure things out. But the more answers you have, the easier that final puzzle will be. The obvious solution is to join the party every single day!
I'm a kid. Can I play, too, or is this only for teachers, booksellers, etc.? Everyone can play! But note that a couple of the puzzles will be a notch or two harder than they are in the books. Feel free to team up with other kids or an adult! I'm sure you can do it.
