Tripong is ping-pong for three.
According to the AP:
Tripong uses an odd-shaped table at regulation ping pong height and Plexiglas "nets" that divide the table into three wedges, each with a neutral zone and scoring zone... Each player starts with one point and it takes three points to win, so players must team up to keep themselves in the game.
This is too complicated for me! I can't even play regular table tennis without it turning into slapstick comedy.
