Ebook: Challenging Optical Picture Puzzles

Sterling Publishing, 1996. — 96 p. — ISBN 0806994401.This collection of picture puzzles contains some very hard ones. Visual puzzles can be very difficult because there is usually more than one way to interpret the characteristics of the diagram. In these puzzles, you are given a sequence of images and your goal is to select what should be the next one from a list of options. While in some cases this is rather easy, there are many cases where authors found it difficult. The solutions are included and while authors did not find a case where the answer was wrong, at times authors remained convinced that my choice was also correct.
Like all collections of good puzzles, this book contains some frustrations. Nevertheless, authors enjoyed working through them and recommend it to anyone with a penchant for puzzles based on sequences of images.
