Rules

Match guidelines

Match format	All matches will be played as best-of-three sets. Sets 1 and 2: Regular sets (first to 6 games, including tiebreaks). Set 3: Super tiebreak (first to 10 points, win by 2 points). At 5-5, a tiebreak will be played.
Deuce & No-Ad rules	In a deuce situation, the No-Ad (No Advantage) rule applies after the first deuce. For the deciding point, the receiving team chooses the receiver. At set point and match point, the No-Ad rule is not used — play continues using the traditional deuce format. In mixed doubles, the receiver must be the same gender as the server (i.e., male vs. male / female vs. female) during No-Ad points.

Schedule changes & no-shows

Schedule adjustments	Once the draw is finalized, any schedule change due to personal circumstances must be communicated to the opposing team at least 48 hours before the match.
Default loss policy	Arriving more than 30 minutes late without notice will be treated as a no-show, resulting in a default loss (6-0, 6-0 in favor of the opposing team). Exception: Notwithstanding the above, teams may freely adjust the match time or schedule by mutual agreement, provided the opposing team's understanding is obtained.

Retirement & disqualification policy

Retirement	If a team retires during a match, all remaining games will be considered a loss for that team. Example: If Team A retires when the score is 4-2 in the first set, the final score will be recorded as 6-4, 6-0 in favor of Team B.
Disqualification	Matches played against a disqualified team will be considered null and void.

Local rules

This tournament is founded on the principles of fair play and sportsmanship. To ensure smooth and fair operations, the following local rules apply. All participants are expected to understand and follow these guidelines.

Self-call and officiating	This tournament follows the principle of self-call as the default. All players are responsible for making accurate and honest calls for balls that land on their side of the court. If both teams agree, a third person may act as an umpire. The self-call principle still applies in this case. If an official umpire is assigned, their decision is final. In unclear situations, giving the call to the opponent is in the spirit of sportsmanship. Please respect your opponent's calls.
Call reversal	If a call is reversed and it did not interfere with the opponent's play, the point continues based on the corrected call. If the reversal affected the opponent's play, the point is replayed as a let.
Late calls	Line calls must be made immediately after the ball bounces. Calls made after the ball has exited the court are considered late calls and are invalid.
Interference	Calling out before the opponent hits the ball is considered interference and may result in the point being awarded to the opponent. Calls made before you or your partner hits the ball are permitted.
Foot faults	Foot faults are a common occurrence in amateur matches. During serve, be careful not to touch or cross the baseline, and be mindful not to commit repeated foot faults. If you suspect your opponent is committing foot faults, you may request an official to make a judgment.
Service interruptions	If play is interrupted by an outside factor such as a ball from another court, the point is restarted with a first serve. This applies regardless of whether the interruption occurred during the first or second serve.
Score calling	The server must clearly call the score before each point begins. If there is a dispute due to a missing score call, the receiver's version takes precedence. If the score was called clearly, the server's version is accepted. Before serving, clearly announce the score to the opposing team to avoid any confusion about the score or court changes.
Order errors	If there is an error in the order of server and receiver, or if a required court change is missed, it must be corrected immediately upon recognition. Points played before the error remain valid, and the match continues normally according to the established rules.

Conduct & etiquette

Cheering etiquette	Since many players are members of social clubs, active cheering is expected. All cheering must reflect respectful sportsmanship. Non-players, including spectators and umpires, are strictly prohibited from making line calls or interfering with play. Inappropriate behaviour, disparaging the opposing team, or excessive noise that disrupts focus is not allowed.
Additional notes	All players must maintain a respectful attitude toward opponents at all times, and refrain from language or actions that could cause discomfort or disadvantage. All participants are asked to balance competition and courtesy in the spirit of sportsmanship. All disputes during matches will be resolved by the tournament organizing committee, and all participants agree not to contest the committee's final decision. As the local rules represent the minimum guidelines for orderly and fair tournament operations, we once again ask for your mature attitude and willing cooperation.
