2Keep at least one die aside (these count for your score).
3Roll with the remaining dice until all 6 are set aside.
4Sum up the total pips.
5Total < 30? You drink the difference (e.g. 26 = 4 sips).
6Total = 30? Nothing happens (or everyone drinks 1, depending on house rules).
7Total > 30? You can distribute the difference to the next player (e.g. 34 = give 4 sips).
8Bonus rule: If you score above 30, you can often roll again with all 6 dice. If you roll the 'difference' matching dice (e.g. fours at 34)? They count double for the next player.
