I've read alot of Brainteaser books and this is the best one yet. There are problems I've been wanting to know the explanations to for years and those problems and the detailed solutions are in this book and all beautifully explained! Thank you for such enjoyment. I also feel that I'm getting more intelligent every day working on the problems. DS

This is the best brainteaser book I've seen so far--it has all the classic puzzles that were on major talk shows for years. My children also enjoyed reading parts of the book as they claimed it helped in their schoolwork.

I want this book so I got the sample and I was dissatisfied. The whole sample was the introduction. What a waste of my time, because I spent my time reading it looking for at least one teaser, but NOPE! I am not getting the book after all. If you agree, share!
