A third is called 40 and if the player scores a fourth point they win the game. However, a player is awarded a game only if he has scored two more points than his opponent. If both players have won three points, the score is called deuce. The next point scored by a player is called advantage for that player. If the same player wins the next point, that player wins the game. If the other player wins the next point, the score returns to deuce and play continues until one player wins two points in a row after the score of deuce. Players alternate service after each game.
