In tennis, the points are advanced in a special sequence: 0 (love), 15, 30, 40, game. In tennis, to score the points, a player has to win a point by striking the ball in such a way that the opponent is unable to strike back within the limits of the court. When 40 is reached by both players, then it is deuce, and a player has to win two points in a row before he/she can win the game.
