What's inside the pack
Crack a secret pattern
A code that looks unbreakable — until your child spots the hidden rule and cracks it in minutes. That first "wait… I got it!" moment is the whole point.
Decode a number system
Real math from Book 1: number systems most adults have never seen, explained the Agency way — story first, trick revealed, superpower unlocked.
Solve a full case file
A complete mission with a story, a challenge and an answer key — exactly what the full book feels like, so you know before you buy.
Quick questions
What age is this for?
Ages 9–12 is the sweet spot. Confident 8-year-olds enjoy it with a little help; many 13-year-olds still love the codes and tricks.
Do I need to print anything?
The pack is a print-ready PDF. Print it at home, or let your child solve it on a tablet with a notebook on the side.
Is this a school curriculum?
No — and that's on purpose. These are enrichment missions: the clever, pattern-based math that schools skip. It works alongside any curriculum, including homeschool.
Do I have to sign up to get the missions?
No. Signing up is the quickest way — the PDF comes straight to your inbox and you'll hear about new books first. But if you'd rather not, there's a direct download link right under the form. The missions are yours either way.
What happens after I sign up?
You get the PDF, plus an occasional note when a new book launches — like Book 2, Field Training, on July 20. No daily emails, and you can unsubscribe with one click.
