Spilled Cup – Rules of Beer Pong #21
21. Spilled Cup
Often in the madness of a chaotic game of beer pong someone spills a cup that is in play. If someone spills their own cup, for whatever reason, the cup counts as a made cup and must be removed. This happens many times when a player tries to block a bounced shot. Check out these beer pong mats to help keep your cups from spilling: beer pong mats. It is wise to keep a towel close to the table so that you can clean any spills on the floor.
If a defender spills their own last cup the defending team loses the game. If the last cup is spilled by the shooting team then the cup has to be refilled.
Some houses play the Randy Johnson Rule and do allow a shooting team to knock over the last cup for the win
