Game Match

Round-robin match for the first day, two 4-team groups play an 8-game pro set match with one deuce, and the second deuce is a “sudden death” game determination point with the receiver’s choice, except for the mixed doubles, in which men serve to men and women serve to women. If a match goes to a 7:7 game score, it will play a straight 5-point determination game, using Coman serve rotation, which changes the side after the first point, and then every 4 points to keep each player serve on the same side.

Best of 3 sets elimination match for the next day, the first two are regular sets with no deuce, like the first-day match, the “sudden death” is the receiver’s choice, except for the mixed doubles. If each team wins one set in the first two regular sets, the third set will be a 10-point super tiebreaker up to 15 points to determine the winner of the match. The super tiebreaker also uses Coman serve rotation to keep the serve on the same side.

比赛规则：第一天小组循环赛 – 每个组别将有两个小组，每组四队展开单循环，无论输赢每队都会打三场比赛，每场比赛要赢八局。如果比分出现七比七时，就打一个抢五分的决胜局，按COMAN规则换发球，即第一分之后换边，之后每四分换一次边，保证每位球手在同一边发球。每局都有一个deuce，第二个deuce就是sudden death判定点，由接发球的一方选择谁接发球，但混双除外，男对男发球，女对女发球。

第二天三盘两胜淘汰赛 – 由同一组别的小组头两名进行交叉三盘两胜淘汰赛，前两盘跟常规赛一样，只是没有deuce，四十比四十时就是判定点sudden death，由接发球方选择接发球，除了混双之外，固定男队男女对女发球。如果比赛打成一比一平，第三盘就是抢十超级决胜局，同样按COMAN规则换发球，平局到第十五分决出胜负。
