If you are playing with a group of friends and really want to drink more than the cards allow, you can introduce snake eyes!
Every time a player rolls a face containing a dot, they get snake eyes. If another player looks into the eyes of the player with snake eyes, they must take a sip of their drink.
A player continues to have snake eyes until another player rolls a face with a dot on the dice. Then the new player gets snake eyes instead of the previous player.
