Crypto puzzles and games for kids


I had a similar book as a kid and I loved it until the covers fell off. How sad was the day I realized I didn’t have any secrets worth encrypting, and no enemy spies were on their way.


The NSA don’t count? :wink:

I’m intrigued. This is the kind of book that my son may just love. However, I did read the sample and was underwhelmed. I was expecting more number games, puzles, encoding/decoding samples, and other things. Maybe they are in the later chapters. Has anyone had a deeper look?
