Standard game A standard game is scored as follows with the server's score being called first: No point - "Love" First point - "15" Second point - "30" Third point - "40" Fourth point - "Game" except that if each player/team has won three points, the score is "Deuce". After "Deuce", the score is "Advantage" for the player/team who wins the next point. If that same player/team also wins the next point, that player/team wins the "Game"; if the opposing player/team wins the next point, the score is again "Deuce". A player/team needs to win two consecutive points immediately after "Deuce" to win the "Game". b. Tie-break game During a tie-break game, points are scored "Zero", "1", "2", "3", etc. The first player/team to win seven points wins the "Game" and "Set", provided there is a margin of two points over the opponent(s). If necessary, the tie-break game shall continue until this margin is achieved. The player whose turn it is to serve shall serve the first point of the tie-break game. The following two points shall be served by the opponent(s) (in doubles, the player of the opposing team due to serve next). After this, each player/team shall serve alternately for two consecutive points until the end of the tie-break game (in doubles, the rotation of service within each team shall continue in the same order as during that set). The player/team whose turn it was to serve first in the tie-break game shall be the receiver in the first game of the following set. Additional approved alternative scoring methods can be found in Appendix V. 6. SCORE IN A SET There are different methods of scoring in a set. The two main methods are the "Advantage Set" and the "Tie-break Set". Either method may be used provided that the one to be used is announced in advance of the event. If the "Tie-break Set" 5
