Beer pong is typically played with four players in two teams of two. The object of the game is to successfully land ping pong balls in the other team's cups by throwing them from across a table. Each team starts with 10 cups arranged in a pyramid. Every time an opponent lands a ball in a cup, that cup is removed, and the first team eliminating 10 cups wins.
To decide which team goes first, two members of opposing teams lock eyes with one another and each throw a ping pong ball at the same time. Whichever team lands their ball in a cup goes first. If neither player lands a ball, their partners repeat this until someone wins. Depending on the rules, players must either keep their elbow or wrist behind the table when taking shots.
Teams can ask their opponents to rerack, or reorganize, the remaining cups twice per game so long as there are six, four, three or two cups remaining. If a player bounces a ball into a cup, two cups are removed from that side. Bounced balls can be swatted away by the defense. At the end of the game, the losing team gets a chance for rebuttal. Each player can shoot until she misses. If cups remain on the other team's side, that team wins. If not, the game goes into overtime.
