Setup: Set up as many plastic cups as you desire in a circle in the middle of a table. Fill the center cup full of beer, and put smaller amounts in the surrounding cups. Players stand around the table in a circle. Gameplay: The game starts with 2 people on opposite sides of the table with ping pong balls and empty cups (or they can drink one of the other cups to start). For games with more people, 3 cups can be used at once. When you have an empty cup, the goal is to bounce the ping pong ball into the cup. If you succeed on your first try, you can pass the cup to anyone you want. If you make it on any other attempt, you must pass to the left. If someone makes a cup, and the person to their left has an empty cup they haven't made yet, they get to swat their cup (generally while yelling "BOOM"). They then pass their cup to the person in front of the one they swatted. The person who's cup got swatted has to drink a new cup and start shooting again. Common courtesy dictates that other players retrieve flying ping pong balls for the person while they are drinking their cup. End of Game: The game ends when there are no more cups left to pull, and the last person to have their cup swatted must drink the full beer.
