Rules compare to normal craps with a twist.
First: Each player takes 1 die each and rolls. The player with the highest number gets to roll first. If you tie, you keep going.
Second: If on your first roll (of each and every turn) you score a 7 or 11, you win. This means that you then roll both dice again and the number that comes up, that's how much the other person drinks.
Third: If on your first roll (of each and every turn) you score 2,3, or 12, then you take both dice and roll to see how much you drink.
Fourth: If you roll a different number then listed above (4,5,6,8,9,10,) then you keep rolling to get that same number. If you roll a 7 or 11 (crap out) then you roll 1 die to see how much you drink. If you get your number, you roll 1 die to see what the other person drinks.
