Gameplay
No "official" codified version of the rules of pong exist, and many "house rules" variations exist. In general terms, players start by assembling cups of beer or other obstacles onto either side of a pong table and placing a median at the center of the table. Like table tennis, pong requires one side to serve the ball and the other side to attempt to return the ball, thus beginning a rally. Both the serve and the intra-game volleys generally must propel in an arch trajectory. Players may not return the ball until it has struck their own side, objects on their side, or the floor. Following the serve, players attempt to hit or sink in the opponents cups, whereby the opponent will lose one or more points. Once all points for a cup or obstacle have been taken away, the object is removed. The game is won when all objects have been removed from the opponents side.
