They are a challenge to our intelligence as their solving is a tonic for our ego; and even where a puzzle fails to arouse our interest, curiosity may still drive us to look up the answer. In this book there is much to challenge and much to arouse the curiosity, and at the same time much to entertain. The whole puzzle gymnasium is brought into use to provide stimulating, but I hope not exhaust­ ing, mental exercise. Here are mathematical puzzles, word puzzles, dis­ sections, exercises in logical deduction, and also a few of what might be called ‘open-ended’ problems, with tentative solutions on which the reader is invited to improve—if he can. The word puzzles calls for special mention. Whereas most words are to be found in most dictionaries, some words and spellings are peculiar to certain ones. Any good dictionary is adequate for all but a few words in the harder puzzles. Our recommendation is Chambers 20th Century Dictionary, which, apart from listing all the words used in this book, has many attractions for the puzzler, not least a clear distinction between proper and improper nouns. The puzzles you are about to attempt have been selected, though many with modification, from those that have appeared in GAMES & PUZZLES maga­ zine and have survived the scrutiny of experts. Even so, it is still possible that a few of the problems could be better expressed and one or two of the solutions 7 improved on. Do not hesitate to write and tell us if you have any constructive suggestions. The puzzles are arranged in ascending order of diffi­ culty irrespective of type, though this grading is neces­ sarily only very approximate as we all have different ideas as to what is easy and what is difficult. A series of short posers—‘Quickies’—have been included, use­ fully to fill odd comers of space and hopefully to fill odd moments of the reader’s time. Quickies have not been graded and some are by no means easy. Solutions to puzzles are given at the end and have been arranged in random order so as to avoid spoiling the reader’s pleasure by permitting an unwanted glimpse of answers to adjacent problems. An index (page 159) follows the solutions. Answers to the Quickies are listed sequentially after the puzzles solutions. I hope very much that you will get pleasure from this book. DAVID PRITCHARD 8
