Scoring

International Scoring - A match shall consist of the best of three or five games at the option of the organizers or the competition. Each game is to nine points, in that the player who scores nine points wins the game, except that, on the score being called eight-all for the first time, the receiver shall choose before the next service is delivered to continue that game either to nine points (known as "Set one") or to ten points (known as "Set two") in which latter case the player who scores two more points wins the game. The receiver shall in either case clearly indicate his choice to the Marker, Referee, and his opponent.

The Marker shall call either "Set one" or "Set two" as applicable before play continues. The Marker shall call "Game ball" to indicate that the server requires one point to win the game in progress or "Match ball" to indicate that the server requires one point to win the match.

Points can be scored only by the server. When the server wins a stroke he scores a point; when the receiver wins a stroke he becomes the server.

Point-a-Rally Scoring - A match shall consist of the best of three or five games and each game shall be played to nine or fifteen points at the option of organizers of the competition.

Where each game is to fifteen points, the player who scores fifteen points wins the game, except that on the score being called fourteen-all the receiver shall choose, before the next service is delivered, to continue that game either to fifteen points (known as "Set one") or to seventeen points (known as "Set three") in which latter case the player who scores three more points wins the game. The receiver shall in either case clearly indicate his choice to the Marker, Referee, and his opponent.

Where each game is to nine points, the player who scores nine points wins the game, except that on the score being called eight-all the receiver shall choose, before the next service is delivered, to continue that game either to nine points (known as "Set one") or to eleven points (known as "Set three") in which latter case the player who scores three more points wins the game. The receiver shall in either case clearly indicate his choice to the Marker, Referee, and his opponent.

The Marker shall call either "Set one" or "Set three" as applicable before play continues.

The Marker shall call "Game ball" to indicate that the server requires one point to win the game in progress or "Match ball" to indicate that either player requires one point to win the match, and "Match ball, game ball" if one player requires one point to win the match and his opponent requires one point to win the game in progress.

Points can be scored by either player. When the server wins a stroke he scores a point and retains the service; when the receiver wins a stoke he scores a point and becomes the server.
