Codes and Codebreaking

A Fun Way to Start Learning Secret Codes and Ciphers

Can you crack the code? Secret messages are everywhere — hiding in plain sight, waiting for someone clever enough to read them. This hands-on workbook turns curious kids (and the grown-ups who can't resist solving along) into confident codebreakers, one puzzle at a time.

Inside, young codebreakers learn to write and crack twelve real ciphers — the same secret-writing tricks once used by Roman generals, Spartan warriors, and master spies. The book starts with simple letter swaps anyone can solve in minutes, then climbs step by step to zigzag rail fences, spinning cipher wheels, and messages locked away behind secret passwords.

Every chapter follows the same friendly path: a true story of where the cipher came from, a clear walk-through of how it works, and a ladder of puzzles that builds from "easy peasy" to "I can't believe I solved that." Hints are there when you want them, and a complete answer key means no one ever gets truly stuck.

Featured Cipher — Chapter Inside the Book

The Pigpen Cipher

Corners, boxes, and arrows that look more like a treasure map than writing. Once you learn the secret, those shapes turn into letters as easily as flipping a light switch.

Where it came from: The Pigpen cipher has a mysterious past. Long ago, a group called the Freemasons used it to keep their records secret — which is why some people call it the Freemason's Cipher. Soldiers scratched it into walls. Treasure hunters used it to guard the way to hidden riches. It feels like a code from a secret club, because it once was. In the book, readers join the Explorers' Club and follow a trail of Pigpen clues toward buried treasure.
