Travel to Mars, explore a Greek temple, stop a runaway train, and solve other imaginative dilemmas in this intriguing book of mazes. Based on subway maps, constellations, honeycombs, and other labyrinths, these puzzles require no math skills — not a digit or equation is essential in this world of shapes, proportions, colors, and sizes. Each maze typically takes only six minutes to solve, and they're suitable for all ages. Solutions appear at the end of the book.
