The puzzles in here range from relatively simple to ones that you could take days to figure out. Really great for people who enjoy these kinds of books, although it might be frustrating for someone who doesn't read a lot of these.

This book was amazing and I totally recommend it

Had me thinking from start to finish. Though you just need to think out of the box and you get your AH-HA moment (which is the BEST!!!!!!)

It was ok. They don't give you enough information to solve some of riddles

This book is a fun book! I've read this book a few times to get more familiar with the riddles and shared some of the riddles with friends and family. It's a definite must-read.
