Book excerpt: Created by an art director at the Puzzles.COM website, these phenomenal original brainbusters-more than 200 of them-will stimulate your potential for thinking outside the box. Arranged from easiest to hardest, they're especially devised for mind-expanding visual solving. And all it takes to crack their mysteries are a pencil, an eraser, patience, and, of course, boundless imagination! Arrange a hinged chain of 11 squares of different sizes into one large square-without overlapping them. Play two-hole billiards on the page, sending two balls into their respective pockets in just two strokes. Figure out how eight patterned cars fit into a checkered parking lot so their colors match the background exactly. Floor plans, tangrams, matchstick puzzles: the variety is amazing.
