Emmet E.R. Brain Puzzler's Delight

Sterling, 1993. - 96 pages.The making up of puzzles has become for me over the years a sort of compulsive habit. Some of the problems in this book obviously date, but most of them have been put together recently. I am grateful to the Sunday Times for permission to reprint "Trips Abroad, " which appeared in their "Brain-Teasers. " None of the others appeared in print before this book.People differ considerably in their attitude to and aptitude for problems of this kind. Some find them an engaging challenge; for others the mind automatically switches off. I believe that most people can get pleasure and satisfaction from such intellectual exercises if they can learn to tackle them with some measure of confidence. The puzzles in this book are of varying degrees of difficulty, and I hope that many readers may be encouraged, by a satisfactory solution of some of the easier ones, to tackle the more complicated varieties. In no case is any mathematical knowledge required beyond the most elementary. The fully worked-out solutions are of course designed to help and encourage those who have little experience of this kind of thinking.
