Summary: Puzzles requiring intermediate mathematical skills
Comment: Marvelous book. I found it better than many books but my friends, who were not that conversant with intermediate mathematics did not like it much. Though this book doesn't require a knowledge of calculus, people who have this level might appreciate the book more. But it has more to do with mathematical 'thinking' rather than mathematics itself.

Summary: A Question
Comment: I just had to question this - the book is rated at a reading level for 4 - 8 year olds, but some of the reviewers mention going on technical interviews and keeping track of columns in Scientific America over a number of years?

Summary: Great collection of what it says it is: prepublished puzzles
Comment: This is a great collection of puzzles from the Master Of It All. However, the book is exactly what is says it is: It is a collection of Martin Gardner's puzzles previously published in Scientific America. That means if you have followed Gardner's column over the years, you will have seen many of these puzzles already. And precisely because they're the "best," chances are you still remember them. Of course my favorite (a monk leaves his monastery and goes up the mountain...) is in there, as are a number of other favorites.

Summary: A great collection of diverse puzzles
Comment: I have accumulated quite a few puzzle books and was never fully satisfied with any of them until I heard about Martin Gardner and decided to pick up one his books. The puzzles are diverse, ranging from word problems to geometry problems.

Summary: A Splendid Collection From The Master
Comment: This is a fascinating collection of puzzles from the master of mathemagics. It's clear and undeniable: if you want the best in fun, challenging puzzles, buy anything written by Gardner or his heir apparent, Terry Stickels. You can't go wrong!!!

So get this one if you are good at mathematical thinking and want to challenge yourself. If you are weak in math and would rather read puzzles that require only logic, cleverness, and lateral thinking only, this may not be the one for you.

The solutions given are very complete and actually take up the majority of the pages in the book.
On a somewhat related note, if you happen to be interviewing in the technical fields you may run across interviewers that ask brain teasers. You'll find many of those problems (or ones that are very similar) in this book. For technical interviewing this makes a good study guide.
