I know this isn't a game, but I saw a cute recipe from Kellogg's. You make Rice Krispie Treats as directed, but use Cocoa Rice Krispies cereal instead. Once it is mixed you shape little bunches of the mix into footballs (about 3 in. in size). Make sure your hands are buttered. Use white frosting to create the threads and ring around the ends for the football look.
Good luck!
