If you have time to kill, you can try to play the Noid Shout Out Game at the Dominos Facebook page (it will be in the left side bar at the bottom of the list.) Join in with other gamers trying to get the highest score since securing the top position will earn you a free pizza (everyone else is out of luck!) You can keep playing to improve your pizza shooting skills.
So far, no joy for me as I can't seem to break the top 50. I don't know how people are scoring so high. At any rate, it's a good way to kill a minute of your time.
