Mind-Sharpening Pixel Puzzles: Visual Challenges for the Logical Mind

All you need is a pencil (and an eraser) to enjoy the twists and tricks, the dead ends and sudden "aha!" experiences, that are yours when you try a pixel puzzle. Start with the puzzles that are merely hard to solve, like the baseball player, the ambulance, and the Liberty Bell. Then go on to the harder ones, like the wedding cake, the elephant, and the trumpeter. Soon you'll be ready to take on the hungry shark, the picture of James Dean, and the astronaut--104 collectible designs in all!
