Popular maths books have come a long way over the years, and that's a very good thing. I read this book as an antidote to other, weightier things – both fiction and nonfiction – that I have borrowed from the library. It is fun, humourous, and richly illustrated. I strongly recommend it, and urge you to give into temptation and try the games as you go along!

(I also got an idea for my teaching from it afterwards, but I read it for pure diversion and entertainment in the first place)
