One side arranges their cups in the traditional 10-cup triangular format, with cups filled to the usual amount for a game of beer pong. This team is the American settlers. When a cup of theirs is hit they must drink and then immediately refill the cup, placing in its original position. The American Settlers will always have a perfect triangle on their side.
The opposing side is the Native Americans. Their side consists of 10 cups in a vertical line, each filled with one entire can of beer. For a cup to be consumed, the American Settlers must hit the cups in perfect order, starting with the cup closest to them and ending with the cup furthest from them.
The goal of the game is for the American Settlers to hit all ten cups in order before they have had ten cans of beer (which is probably around 50 hits by the opposing team).
When the Native Americans have finish a beer, they can place the empty cup anywhere on the table as a decoy. If the Settlers hit this cup (or many of these cups) they have to drink that many respective cups from their triangle. This is an important and game-changing rule.
If at all possible, Bollywood music should play at all times (as to support a hilarious play on the 'Indians' pun)
