Serving Serving
Tennis players blow on their fingers before serving or hitting the ball to improve their grip by removing moisture and enhancing friction between their fingers and the racket handle. This helps them have better control and accuracy in their shots.
By serving
In table tennis, serving rules require the ball to be tossed at least 6 inches in the air before serving, and the serve must land on the opponent's side of the table and bounce once before being returned. Additionally, the serve must be hit from behind the end line of the table and alternate between the two players after each point.
In USTA doubles tennis matches, the server must stand behind the baseline and alternate serving between the two teams. The serve must be hit diagonally across the court and land in the service box on the opposite side. The server must also call out the score before serving.

Serving an ace in tennis is worth just as many points as serving, playing the point out, and winning it. In other words, one point.
