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

This book looks like its a self bound collection of worksheets

Not suitable for the age they recommend. It is very difficult

This is cheaply made with lots of grammatical mistakes (even on the first page.) There are much better code/spy themed books for children available. I think this might be made by Amazon as it doesn’t have an advertised author and I had a similar experience with a cheap and rubbish children’s Ancient Egyptian activity book made by them.

Great book, already bringing hours of entertainment for my grandson.

Cool book

Contains errors in the first puzzle. Glad I was helping my child with it because they would have been lost because of the errors

A fun idea, but not a super attractive format for my kids. They have found similar books more appealing. I enjoyed doing them on my own though.

He loved it

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.
