Ball of Confusion: Puzzles, Problems and Perplexing Posers Hardcover – October 1, 2011
Fun maths teasers and brain-bending puzzles from TV boffin Johnny Ball, from his slot of the same name on Zoe Ball's Radio 2 show. Think of your house number (as long as it's got two digits). Double it. Add 5. Multiply by 50. Add your age. Add the number of days in the year, 365. Subtract 615 and check the result. The first digits are your house number, the last two are your age. But why? Johnny Ball is well-known for his TV shows in the 1980s such as Think of a Number and Johnny Ball Reveals All. The Ball of Confusion slot first appeared on his daughter Zoe Ball's BBC Radio 2 show in 2008 and has since proved hugely popular, inviting enthusiastic audience participation from across the country. Ball of Confusion features puzzles and problems from the show as well as many more, designed to twist your brain into enjoyable knots of empuzzlement and designed for every level of difficulty - from some solved in a twinkling of an eye to some that will knit your brow for hours. From how to cheat in a coin toss to why it is that some parts of a high speed train travelling at 125mph are actually going backwards, Ball of Confusion will bend your mind in places it's never been bent before. Can you keep up?

Great book, but dispute some of the answersReviewed in the United Kingdom 🇬🇧 on December 11, 2013
I have enjoyed this book a lot, and the terrible puns remind me of when he was on TV (in a good way). I would give it five stars, except for a couple of the puzzles where I was not sure that the solutions were actually correct, or would query whether the question is precise enough to lead to that particular solution. But very good fun, and his personality comes across which is very welcome.

A Good Holiday ReadReviewed in the United Kingdom 🇬🇧 on June 10, 2016
As the title says, I bought this to read on a holiday. It's good for testing the grey cells; some questions I was able to do, some not. Some; well, life's too short to work out or be bothered with!
Not really suitable fpr a KindleReviewed in the United Kingdom 🇬🇧 on December 31, 2012
I downloaded this interesting book to my Kindle. It has some interesting facts, puzzles and problems etc. But the explanations are scattered further on in the book and the Kindle does not really lend itself to moving back and forth looking for the answers. However as a book I found it very interesting and enjoyable.
