Cards are worth face value in drinking seconds - Jack is 11, Queen is 12, King 13, Ace is 21 and you get to make a rule.
Dealer starts by calling a suit then begins to deal the cards to the players until that suit comes up. The first person to get dealt that suit has to drink for the appropriate amount of seconds and before they put their glass down they have to call the next suit. If they forget to call a suit before they put down their drink they must drink again. As rules are implemented anyone breaking a rule must drink the same amount as the person who has been dealt the suit of choice - if they are also the person who got the card they must double the face value of their card.
Rule Ideas : Only drink with left hand, can't swear etc.
