Fill the extra cup about 1/3 full of beer. The first person rolls all five dice. Any dice that is five or adds up to five equals zero, and you put those dice off to the side continuing to roll with the rest of the dice. The same person rolls until he rolls nothing that can be a five. However much the dice adds up to is his/her score continuing on to the next person. Who ever at the end of the round has the highest score has to drink the cup of beer. As the game continues on the cup gets fuller, because the last person to drink gets to fill it for the next person to drink.
