2 decks of cards
1. Sit everyone in a circle. The first person draws a card. The next person draws a card.
a) If both cards are related (same value or the same suit) then both players must drink the number of sips as on their own card. (jack=11 drinks, queen=12, etc.).
b) If they have both have the exact same card then they have to drink double the face value.
3. The next person in the circle is the one who gets to count the sips the first two are drinking, as fast or slow as he/she wants. But, and this is a big but, if one of the drinkers finishes their beer before the counting is done, then the person counting has to finish his beer.
Note: It is best to play this game with cans of beer or cups so you can bluff as to how much beer you have left.
