Tie-Break Rules

A Tie-break game or tiebreaker is either played to 7 points (to resolve a set) or 10 points (to replace a third set). The player or team must win by 2 points. Change ends at multiples of 6.

Coman Tie-break Rules 

The Coman Tie-break procedure is the same as the regular tie-break (set or match), except that players change ends after the first point, and after every four points thereafter. (i.e., change ends after the 5th, 9th, 13th, 17th point, etc), and at the conclusion of the tie-break.

The scoring and procedure in the Coman Tie-break is the same as the traditional set or match tie-break. For example, if the Coman Tie-break procedure is used when the set score is 6-6, the player whose turn it is to serve shall serve the first point from the deuce court; after the first point, the player(s) shall change ends and the following two points shall be served by the opponent(s) (in doubles, the player of the opposing team due to serve next), starting with the ad court; after this, each player/team shall serve alternately for two consecutive points (starting with the ad court), changing ends after every four points, until the end of the tie-break game.
