directors to already know who plays whom by the time given players are finished with a round, rather than making the players wait until all players have finished playing a given round before being able to start the time-consuming pairing process. Commonly used in Australia, and now in many other countries, is a system known as "Australian Draw". Whereby each round is paired using a normal #1 plays #2, #3 plays #4, etc. except that repeat pairings within a selected range of previous games is forbidden. Often, for shorter tournaments the selected range will be since the very first round of the tournament, thus never having a repeat pairing for the entire tournament.

Ultimate Frisbee Windmill Windup, a three-day yearly Ultimate Frisbee tournament held in Amsterdam, was the first event in ultimate to introduce the Swiss draw system into the sport in 2005. In later years, many other tournaments started using this format, like Belgium's G-spot, Wisconsin Swiss and many others. For each round, teams earn victory points based on the score difference of their win (or loss). In this way, also a team clearly losing a game is encouraged to fight for every point in order to get more victory points. After each round, teams
