The Willemer rules have been introduced to simplify the count atfacilitate tournaments. Here, the principle of the winning sets isreplaced by a simple scoring system.
The game is won when a player gains 33 points and has at least three points distance to the opponent.
The service will change every five played points. If one of the players reaches 33 points, the service changes after every rally.
Changeover is done, if one of the players achieved 16 points.
