The Junior Code Breaker Book: 50 intriguing code puzzles to crack: can you solve them all?

Best purchase for a curious 7yr old

My 10-year-old granddaughter loved this book and wanted another one in no time and I only see one more on Amazon, so I was hoping there were more to choose from.

I tutor an autistic teenager who, by his own words, "hates learning." He loves the puzzles. He's the most engaged I've EVER seen him.

There was one typo, but otherwise this was so much fun to work through! Each puzzle is unique and have varied levels of difficulty! It took this grown up help from other grown ups! It was a blast!!!

Challenging but fun puzzle book! Would have loved to see answers for the bonus puzzles but so fun!

Way too hard for age that it says can do it.

Overall, an amazing code book (especially for fairly new code breakers, although I’m sure more advanced decipherers would enjoy it too!) I completed within 24 hours, however that’s just because I got obsessed from the very first code. I would recommend having at least some experience with deciphering (e.g. reading up on Pig Pen puzzles etc) but with the helpful clues at the back of the book I’m sure anyone could complete the book. One small error in code 19 where it suggests that CATCC stands for Charlie and The Chocolate Factory (should be F instead of C at the end) but that doesn’t actually influence the overall answer of the code. I particularly enjoyed the bonus questions (and the Pig Pen questions because I’ve always loved that style of code!) Thank you Dan and Andy for such an enjoyable code book!

My 7year old and I had a really good time working through the codes. The hints are brilliant and now, he wants to be a spy when he grows up!

Great nephew starts high school. Workouts for the brain are underrated. Thinking in a different direction can only be helpful

The book does have a few spelling errors (not including the puzzle that is about spelling errors) One of the puzzles if figuring out initials of famous children's stories but the first one is mislabeled CATCC instead of CATCF. I do enjoy that there is both an answer key and a separate hints section too. The hints are sometimes very necessary to figuring out what you are supposed to be doing.
