I want to take this chance to express thanks to a number of people in and around this curious and addictive field of recreational mathematics: to the still lively shades of Lewis Carroll, Rouse Ball, Dudeney and Sam Loyd; to Eddington for his marvellous cricket problem; to Hardy and Littlewood and Coxeter for tucking so much pleasure into serious maths; and to two M.G.s included in my dedication for providing us with so regular and varied a diet. The diet we want—to speak for my own kind of addict—is not just tidy morsels from established recipes, tasty and welcome as those are, but pushings out into fresh areas and quiet encouragement to try our own hand at developing new seasonings and new dishes. And that is what the Mathematical Gazette and Martin Gardner consistently give us.

As for the puzzles in this book, I make one particular request to the reader: please don't take my solutions too much on trust. Like chess problems, puzzles—even those set by the eminent and excellent—can quite often be 'cooked'. I have checked what I say with some care, and I haven't consciously cheated, but I shall be surprised if I haven't made mistakes. And I really should like to hear from anyone who disagrees with an answer I have given, or can improve on it. So far as I am able, I shall be glad to answer letters of that kind.
