RULES  OF  BEERPONG
Illinois State University rules

Each team consists of two players.
Cups will be positioned in a triangular shape on the table.
The object of the game is to throw your ping-pong ball into the cups, which will be filled with beer.
When you sink a ball, the other team will have to drink that cup. *Do not move the cup until both players have thrown*.

If both players sink their ball, then the other team drinks those cups and you get the balls back to throw again.

If you both sink your ball in the same cup, the other team will drink that cup plus any two other cups, and you will get the balls back.

If you bounce the ball and it goes in a cup, the other team will drink that cup plus one other. 
However, if you choose to bounce your ball, the other team can knock your ball away before it reaches the cups.

When you only have 6 or 3 cups left, you can call for a “RERACK” in which case the other team will arrange your cups in a triangular shape again.

If the other team sinks the ball in the last cup, you have the chance for a rebuttal, in which case you have to make every cup until there are none left. 

If a cup falls over either by you knocking it over by mistake or the ball knocks it over, it is counted as sunk and it must be taken away.
