FOREWORD
Most people are content to go through life with their brain ticking over at a mere fraction of its true capacity. This book is not for them. Our intention is to present a mind workout that will bend, stretch, and squeeze your mental powers to the very limit. We start with some I.Q. development tests. Everyone has some level of intelligence. It is formed very early in life and then becomes fixed so that you will never exceed that level. However, just as you can develop your muscles with exercise, you can make the most of your mental powers by using them to perform increasingly difficult tasks. The puzzles in this section start off easy but rapidly become more challenging. The second section of the book is concerned with quite another type of intelligence. Solving the mind-bending mazes we have created will take quite different skills, and will help to develop a whole area of mental power you did not know you possessed. We have taken traditional patterns from all over the world and turned them into labyrinths of fiendish complexity. If you can figure these out, you need never get lost in a strange town again!
6
TO THE I.Q. TESTS
We have put together this series of puzzles for your amusement. In each of the tests the correct answer is to be found in one of the shapes. Proceed through each test as quickly as possible and first answer those questions you find easiest. Then return to the more difficult ones. Check your answers, when the time is up, total the correct answers and then find your fun I.Q. score from the table.
