Crayon Physics Deluxe is a puzzle game that can teach your kids some physics. Play is drawing-based, wherein your cursor becomes a crayon, and once you draw something it immediately assumes mass and weight. Although kids as young as age 6 and 7 can play the early puzzles, the later puzzles are better for kids age 8 and up. Since there's no story line, this is a game best played by kids who like to do puzzles.
