    5.0 out of 5 stars Classic puzzle book, great for mathematics and programming
    Reviewed in the United States on May 5, 2013

    This is an all-time classic book that I first read as a little boy. I never forgot the lesson learned from "Carpet Confusion". The book is divided into different sections such as geometry, logic, etc. Programmers will find several of the puzzles very interesting and relevant to algorithmic design. The book also has puzzles touching on number theory such as the Chinese remainder theorem and Euclid's algorithm. There are stick figure drawings that illustrate each puzzle. The format is that first an easy problem is given, and right after the answer. Then a tougher question along the same lines is posed to the reader. You turn over the page to see the explanation. This page usually has a theory discussion after an explanation of the answer and then some follow-up problems with answer in the back of the book. Great for getting the intellectural juices flowing, finding interview question ideas, boning up for the SATs, whatever, its a classic.

    This is a wonderful book that I bought for my nephew as a gift. I wanted a new one and the book was listed as New and when I got it it clearly had an emboss that said "From The Library of..." I wish the vendor had been more accurate in the description and did not list it as New. If I was going to buy a used one, there were mony more to choose from at much more reasonable prices.

    A great book to get kids, and you, thinking. My son is 7, enjoys math, and has had some good fun with these logic puzzles. He often needs me to help guide him to solve the problems, but enjoys and understands the solutions. fun!
