Roundnet (Spikeball) uses rally scoring: every rally wins a point for somebody. Games are commonly played to 21, win by 2, with shorter games to 15 or 11 used in pool play when a tournament is pressed for time. Bracket matches are often best of three.
Standings in pool play are a win-loss record, then point differential — points scored minus points allowed across all games — to separate teams with the same record.
