From the page: "King: Waterfall - This can be extremely hard, depending on your group of drinkers. It goes in order first being the one who picked the card and so on. The first person drinks as much beer as they can continuously and the 2nd person can't stop until they stop, the 3rd person can't stop until the 2nd person and so on. If you have big drinkers at the begining, it is really difficult."
