My dog, Buster has been making up his own games since he was a pup. When we first gave him a tennis ball he'd bat it around with an old shoe or other object he'd find - like soccer (or maybe hockey). Then he invented "vole". He hides the ball under the skirt of the sofa and pounces on it. (Watch a wildlife show on coyotes or wolves - this is how they hunt) Last year he discovered boxes. When he sees an empty one around he "hints" that he wants it. We put his balls in it and he carries it off to get them out! Once the box is destroyed, he brings us parts of it along with a ball to wrap in it and has just as much fun getting the ball out again! What a character Buster is when it comes to playing!
