Spot the Difference

Book excerpt: Attention to detail is often said to be lacking in the modern, bustling world in which we live. Have you an eye for detail? Just how good will you prove to be at spotting when something is different? These pictures will test your powers of observation to the limit. In addition, there are puzzles which challenge you to spot just one difference, or to spot where things are hidden or missing; there are also reflected pictures, 'spot the same', negatives, and many other picture puzzles to provide variety, and to add to your puzzling pleasure. Five levels allow you to warm up and work your way to expert level.
