One Up, One Down Number of Players: 5 - 10 "One up, one down" works best with a large group of drinkers arranged in either a circle or semi-circle with one person acting as an MC of sorts. The rules are pretty simple, figuring them out can be difficult & often there is an moment of epiphany where you realize how the rules work. (Then again, some people will never figure them out, probably from drinking too much as a result of losing.) In any case, the MC must already know the rules (and is usually the one who starts play). The MC moves around the circle calling out the name of a participant. He/she then asks "One up, one down?" The player has a choice of 3 different answers: a. one UP, one DOWN, b. two UP, or, c. two DOWN. Depending on the position of their own arms their response will be right or wrong. If the person has both arms in a "down" position they must answer "two down" or take a gulp of their beverage. If they have both arms up the correct answer is "two up". If they have one arm up and one arm down then they must answer "one up, one down". Play continues around the circle for as long as the players like or until everyone is zonked. The key here is, of course, that the rules are NEVER explained to any participants that can’t figure them out. The MC simply waits for the current player to answer and if the answer is wrong they order them to drink.
