<Tr> <Th> Alcohol used </Th> <Td> beer </Td> </Tr> <P> Beer pong, also known as Beirut, is a drinking game in which players throw a ping pong ball across a table with the intent of landing the ball in a cup of beer on the other end . The game typically consists of opposing teams of two or more players per side with 6 or 10 cups set up in a triangle formation on each side . Each team then takes turns attempting to shoot ping pong balls into the opponent's cups . If a ball lands in a cup (known as a' make'), the contents of that cup are consumed by the other team and the cup is removed from the table . The first team to eliminate all of the opponent's cups is the winner . </P> <P> Beer pong is played at parties, bars, colleges / universities and other venues such as tailgating at sporting events . </P> <P> The game was originally believed to have evolved from the original beer pong played with paddles which is generally regarded to have had its origins within the fraternities of Dartmouth College in the U.S. in the 1950s and 1960s, where it has since become part of the social culture of the campus . The original version resembled an actual ping pong game with a net and one or more cups of beer on each side of the table . Eventually, a version without paddles was invented and the names Beer Pong and Beirut were adopted in some areas of the United States sometime in the 1980s . </P>
