This book is good if you like puzzles. I like puzzles but this was too challenging. Even the easy puzzles were difficult and made no sense. It was kind of fun to try, but it got frustrating really fast.

I loved reading this book and testing all the riddles on my friends. The riddles were very difficult and had me stumped! I wouldn't recommend reading it all at once, though. It can get a little boring, but otherwise I would definitely recommend it. Pick this book!

This book is amazing…well it is actually not really a book it’s a puzzle book it has awesome riddles! I do recommend this book to people who like riddles.

This book is very clever and if you want to challenge yourself, I would choose this one. But, the puzzles were very challenging and I only got one of them right. Also, when looking at the pages with the answers, you need to cover the answers for the questions you didn't do yet. I learned the hard way.

I read some of it not that COOL.
