Berlin Style Ping Pong is a great way to meet people and be social.

How do you play? A group of people surround a table, whoever is in the server spot serves the first ball to the person directly across from them, and then moves out of the way, to the right. The person to the server's left takes their place and the rest of the circle moves counterclockwise. If someone messes up they are out. When there are two players left, they play until someone scores three points and wins. Bring paddles.
