One person is the dealer. This game is best when more than six people are playing. The dealer goes to his or her right. The first person guesses red or black, if they are correct they may *give* a drink to any person at the table. If they are wrong, they *take* a drink. If they guess three times correctly, they get to make a rule (e.g. No elbows on the table.) As they game continues everyone watches each other and if a rule is broken, that person must *take* a drink. The game ends when the first person throws up or passes out.
Some really great rules I've heard:
