    This is the first book by Martin Gardner I read - and I have been a fan ever since. Just thinking of this book fills me with nostalgia.A lazy summer afternoon: the youth section of our city library, housed in an ancient mammoth of a colonial building: the musty smell of old books: the summer vacation stretching in front of me... and the pretty girl who sat across me at the table, at whom I stole glances now and then, but never got up the courage to speak to...Ah, the halcyon days of youth!...

    I made the dumb mistake of starting to read this book on the train on my way to work.Rule number one: Do not open this book unless you have access to paper, pencils, a ruler and a flat surface. This book requires three-dimensional aides.

    This author was recommended to me when I was 21, by a high school friend who is now an artificial intelligence expert. I'm probably too dumb by now to understand math, but I'll give it a try.

    When I was a sophomore in high school in 1956, I remember going to the library once and seeing a magazine I had not noticed before— the Scientific American. I thumbed through it, and in the back was a column titled ‘Mathematical Games’ by Martin Gardner. Unlike the other articles in the issue which were hard to understand fully, Gardner was very lucid. He talked about folding strips of paper into fascinating shapes called ‘Flexagons’. I did not find out to much later that it was his very first column in the magazine and that I had climbed aboard his bus at the very first stop.What amazing and so well presented topics he covered: Tic Tac Toe, Probability Paradoxes, The Tower of Hanoi, Memorizing Numbers, … For the next twenty five years he kept turning them out, and they were anthologized into thirteen volumes. I have a copy of them all.Don’t let the word ‘Mathematical’ scare you. Everyone can enjoy what is called ‘recreational’ mathematics—especially the way that Gardner presents their concepts. His writing instilled in me, among other things, a delight in puzzles—especially ones that can be stated simply but sometimes had solutions of surprising beauty.

    Martin Gardner was a columnist for Scientific American, and notably described himself as a recreational mathematician. When I found this out, I already loved him, it was just a matter of negotiating the degree. I sat down with this book, a pad of paper, some colouring pencils and a cup of tea. Two hours later I was grinning broadly and surrounded by hexaflexagons. Best few quid on Amazon I have spent in ages, and recommended to anyone who thinks maths is pretty but you wouldn't want to do it for a living. This book is accessible, broad, clever and playful. It is full of good anecdotes, card tricks, elegant puzzles, and clear explanations. There is a piece of commentary on knight/liar puzzles that, if it weren't two pages long, I would copy out right here, because it is the most ingenious and off-the-wall solution I have ever come across.This may come across as a little condescending, but part of me pities people who insist they wouldn't like a book called 'Mathematical Puzzles and Diversions'. They are quite possibly lingering under a misconception about how difficult numbers are or how opaque (or rubbish) the humour is, and either way they are missing out on an awful lot. Get a copy. It's really sad that this book might be considered 'niche'.

    Hexaflexagons is the first of Gardner's series of Scientific American compilations, all now available as PDFs on a single DVD. It hearkens back to the halcyon days of nerdery before the Internet, when instead of watching youtube videos and writing python code, math geeks sat around folding strips of paper in certain ways. The chapters aren't terribly even; some are much more interesting and thought provoking than others. My favorites are the nine puzzles chapters, which are collections of easy but thought provoking brain teasers. Some of the game analysis is fascinating, but Gardner assumes that everyone is deeply familiar with and enjoys chess throughout the book (I'm not and don't), yet goes into detail explaining how one might create different shapes out of four attached squares; surely the assumption that people know the rules of chess but have never seen tetris is a sign that the columns are a bit dated.

    An interesting collection of logic puzzles, game strategies, and interesting physical/mathematical curiosities. I say interesting, despite the fact that there are plenty of sections wherein I definitely lost interest, for while I find math interesting in the abstract I am not accustomed to the kind of thinking it requires. I did not force myself to understand it all, nor beat myself up when I failed to tease out the answer to a posed problem, though. I was just along for the ride, and it was pleasantly diverting at that.

    What an incredible collection of mathematical brain candy. I discovered hexaflexagons from YouTube user ViHart this past school year. I showed the videos to my math classes, and they were hooked. Getting to read the original essay that introduced hexaflexagons to the general public was a joy. There is so much material in this little volume (quite a bit of it genuinely challenging for me, and my degree is in mathematics!) that I'm sure I will return to it again and again.

    My dad gave me his copy of this book. I think I was in high school. My interest in his work hasn't waned one iota since. He truly is the king of recreational mathematics. And, yes, that really is a thing.

    I just recently discovered this author and his huge library of books. I plan to read others. they are great distractions although I plan to spread them out. Too many puzzles at a time takes away some of the fun.

    Uptill now I really like the book and its puzzles. I think that it explains the maths behind it quite well and the book has got a quick pace making it a fun read. It also makes every chapter independent from the next which means if you are very interested in only one chapter of it you can read it.

    I love these books, though I don't share a Gardner's enthusiasm for topography. Nearly timeless puzzles.

    Love it. Love Martin Gardner. An excellent adventure in recreational mathematics!
