(Almost) Impossible Mazes, Balloon Books ISBN 0806980591
Five out of five stars
As the title suggests, the traversal mazes in this book are very difficult. While not long, the degree of difficulty exists because it is often very difficult to determine whether there is an opening between the objects. For example, “Are routes made impassable by blades of grass?” Even when the path is open, it is often very narrow and difficult to discern.
Visually and mentally challenging, these mazes will keep you occupied, albeit frustrated. Which of course is the very definition of what makes these problems entertaining.
