Table tennis games are played to 11, win by 2, and matches are best of five or best of seven games.
For group standings, the ITTF’s competition regulations award 2 match points for a win, 1 for a loss in a match that was played, and 0 for a match not played or not finished. That third case is the point: a player who turns up and loses ranks above one who does not turn up.
Ties are broken using only the matches between the tied players — match points first, then the ratio of games won to lost, then the ratio of points won to lost. Club leagues are often team events, with each fixture made of several singles and a doubles, and keep a team table of fixtures and sets won.
