Beer pong (also called beirut, lob pong, and other names) is a drinking game in which players throw a ping pong ball across a table with the intent of landing the ball in one of several cups of beer on the other end. The game typically consists of two two-player teams, one on each side of a table, and a number of cups set up on each side. There are no official rules, so rules may vary widely, though usually there are six or ten plastic cups arranged in a triangle on each side.[1] The number of players on a team can vary as well, from one to three or more.
When a ball lands in a cup, the defending team must consume all of the beer inside that cup. The game is won by eliminating all the other team's cups before one's own cups are eliminated. The losing team must then consume all the beer remaining in the winning team's cups.[1] The order of play varies – both players on one team shoot followed by both players on the other team, or players on opposite teams can alternate back and forth.[2]
