There are crime names and Christmas mazes, country mazes and city mazes, mazes for all skills and mazes for all seasons of the year. There are even mazes that are games you can play over and over again. Each maze has a story to go with it and often a set of hints and complications. The illustrations are all printed in large size (perfect for framing or creating in craft or needlework for even more amazing fun). Some are classical mazes: others are solid mazes, ripple mazes, short-path labyrinths, avoidance labyrinths, mazes in which you have to visit all rooms and mazes that test your skill in countless other ways. Also included is an introduction to the history of mazes and a special section on maze solving. If somehow you don't get one of the mazes or feel you have to test your own conclusions, a solutions section in the back gives full information.Walter Shepherd has made another significant contribution to cerebral recreations in this volume.
