Once you assemble the jigsaw puzzle, you'll need to decode Riley's message! But Zip's here to help! On the postcard in the box, Zip drops some useful tips to get you started. Here's the gist.
1. Note what you’re looking for Riley’s message will be a word or phrase. But it won’t be in plain sight! You’ll have to do something clever to get to it.
2. Note what’s going on Where Riley and Zip are and what they're doing hints at how you should decode. Riley and her freedom fighter pals are electrical engineers, so they aren’t going to send their message through interpretive dance.
3. Think of letters as numbers Riley’s a unique thinker—her brain often interchanges numbers with letters. So think of A as 1, B as 2, Z as 26, and vice versa. Which means you can also do math with letters! For example, A + D is E and 10 - 3 is G and Y + 2 wraps around to A, and so on.
4. Look for patterns Observe! Find examples in the assembled scene that demonstrate how things work, and use that knowledge to complete anything missing.
5. Get more help If you get stuck, don’t despair! Zip is available online 24/7 to provide detailed hints. You can also check if the answer you got is right, or read Riley's full explanation of the solution.

My 7 year old, who loves math, was able to play the easy version while her 20 year old brother who majored in math played the hardest level and it was a fairly even competition.

Working the two Master Theorem books has been a joy - by far my favorite "puzzle books" of all time. Thank you (and the TMT team) for these incredible time-wasters!
