I haven't found anywhere that actually explains how the game is played, but apparently someone has finally invented a way for three people to play ping pong at the same time. He calls it TriPong.
Secil Boyd built a whole new table for three people to play. From reading the article, it sounds like there's some level of teamwork that has to happen in order to beat the other two players. I really have no idea how it works. If you find out how to play, please let me know. I think ping pong is fun enough with two or four players, but I'd love to try this game. We'll see how popular it gets.
I think it would be sweet if there is still a way to play normal ping pong as well. And if it's possible to have six players play on teams. We really need more information on this.
