You start with 5 dice. Roll all dice. Set aside 
all threes every roll and roll rest of dice. If 
you roll no threes, keep lowest dice.
Keep going until all dice are set aside. Once 
everyone has gone, lowest total wins. When adding 
3's count as zero.

The losers drink as many times as the winner's 
total. As in all dice games, the winner starts 
next round.
