Mazes that shimmer, advance, recede, jump, pop, and wiggle — here are 40 mazes, all incorporating op-art effects and other visual illusions designed to challenge your search for the solution and to add to the enjoyment of finding it. Created by master maze-master Dave Phillips, all of the mazes are ingeniously designed. The exciting variety of mazes include several 3-D mazes, eccentric circles, spirals, wavering squares, a two-page fortress maze, and many others. There are mazes where you start in one area and finish in another and others where you pass through three or more areas only once, without retracing any paths. Directions and solutions are provided in the back.
