Secret Code Breaking Puzzles for Kids: Create and Crack 25 Codes and Cryptograms for Children aged 6 to 10. Great as a Gift for Junior Spies

It’s clever and a great idea for kids, but it is poorly made and not built for 6 year olds. I would suggest to a 10 year old. It’s fairly advanced. My issues with book: The numbers/letters for the crypto code don’t line up properly so it makes it a bit confusing. We had to make our own lines for letters during decryption. I would maybe pay $2 for this book.

I feel like this book is trying too hard to be politically correct using "their when it should be his or hers" when using possesive adhectives. I feel like this confuses children who are learning grammar. Maybe the book should describe their intent with this in the description and be more clear about it.

Way toooo hard for my kids

I was about to buy this for my code-loving kids, but the grammar in just the sample turned me off.
