Feenstra M., Carter P.J., Harding C.P. The Ultimate IQ Challenge

Ward Lock Ltd, 1994. - 128 p.The authors have created a collection of 100 puzzles and three IQ tests that should give hours of challenging fun.It is with great pleasure that we present our second volume of original puzzles and tests from around the world compiled by members of High-IQ societies. We hope that as a result of this book many of the puzzles, which may have otherwise been lost to time or not even compiled, will become classics in their own right. Collectively they demonstrate a high level of creativity, which we are sure you will find entertaining, challenging, often amusing and always thought-provoking. We believe that once you put your mind to work and think laterally, on the look-out for the unexpected, you will start to come up with many of the correct solutions.
