Rules

In a ITT match, each team is composed of two men, two women, and a coach. Team matches consist of five sets, with one set each of men's and women's singles, men's and women's doubles, and mixed doubles. The first team to reach five games wins each set. A nine-point tiebreaker is played if a set reaches four games all. One point is awarded for each game won and scoring is cumulative. If necessary, Extended Play and a Supertiebreaker are played to determine the winner of the match. 

Scoring is no-ad (first team to win four points wins the game).

Game scoring is 1, 2, 3, game.

All games, sets, and Supertiebreakers are won by a margin of one point.

Each game counts as one point in the team's cumulative match score.

The receiver has the choice from which side he/she will receive serve should the game reach three points each. In mixed doubles, the serve is always gender-to-gender at 3-3.

Teams change sides every four games.

Let serves are played.

The first team to reach five games wins a set. If the set is tied at 4-4, a 9-point tiebreaker is played.

If the team ahead in the cumulative score wins the final game of the last set, then that team is the winner.

If, however, the trailing team wins the final set, the match is sent into Extended Play and continues until       

a) the leading team wins one game, or b) the trailing team ties the match score.

If the score becomes tied, the match is decided by a Supertiebreaker.

If the match is tied at the conclusion of five sets OR if the trailing team ties the score in Extended Play, a 13-point Supertiebreaker, involving the same fifth set, decides the outcome of the entire match.

A coin toss determines the choice of side, server and receiver. Players change sides after six points.

The first team to win seven points is awarded a single game and the match
