Scramble Squares: Kittens
Siamese, Persian, butterscotch, and calico kittens chase a ball of yarn across this hot-pink  puzzle. 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 playful kittens 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
