Basically, one person needs to be a bartender serving those who are playing. The person who has the deck, says "Red or Black?" and the players have to pick. Then the person with the cards cuts the deck in half or pulls of the top, it doesn't really matter. If they chose correctly, they do not have to take a shot. But if they chose falsely, they have to take a shot or down a beer. The game only ends when everyone ends up on the floor, laughing and passing out.
