iFling is a simple, free and surprisingly addictive iPhone game where the player has to catapult a ball using the motion sensors. To get a high score, you must pay attention to the rhythm and timing of your catapult throw.

After you’ve tossed the ball once, try to beat your high score. Once you learn the basic controls, you can throw the ball quite far.
