Scramble Squares: Football
Don your helmet and pads for this tough-as-nails version of a gridiron challenge. Easy to Play,  but Hard to Solve is the motto for this deceptively simple-looking puzzle. By the time you've become  addicted and find yourself unable to solve the thing, you'll realize it's not so much a motto as a warning.  Nine colorfully illustrated cardboard 4-by-4-inch squares depict various unfinished images of quarterbacks,  running backs, wide receivers, and linebackers along their edges. The images must be matched and the nine  squares arranged in a larger square. An ingenious, elegantly executed puzzle idea, Scramble Squares will  have you simultaneously blessing and cursing its inventor.--Claire Dederer
