Entertain and challenge your brain with this bonanza of puzzles. Thirty mind-boggling mazes, created by a master maze designer, include labyrinths involving 3-D constructions, directional arrows, over-and-under structures, as well as key mazes, surface mazes, designated stops, and much more.

The puzzles are designed around clever themes and are categorized by difficulty into five levels–from “No Brainers” that take about five to ten minutes to solve, to “Full Brain Overload,” mazes that might take hours to find a solution. (A picture of a brain with varying amounts of gray matter appears next to each maze to indicate its level of difficulty.)

There’s also a “hints section” that provides clues for all but a few of the easiest puzzles. Use the hints section if you get stuck, but working the easier mazes will help you solve the more difficult ones. So grab a pencil and a-Maze yourself!
