Mastering Tennis, Judo, and Gymnastics: Rules and Skills

Tennis Rules and Fundamentals

The tennis court includes the net, sideline, baseline, center mark, double sideline, and centerline.

Scoring System

The scoring sequence is as follows: 15 (first point), 30 (second point), 40 (third point), and game (fourth point). If the game is tied at 40-40, it is known as a deuce; in this case, the game continues until one player wins by a two-point lead. A point is awarded when the ball touches the ground in the opponent's area and they fail to return it.

Tie-Break and Sets

A player or team needs to win 6 games to win a set. If the score reaches 5-5, a player must win the next two games to win the set.

The Server

The server (saque) is allowed two serves, which are repeated if the ball goes out or touches the net (a let). The player must stand behind the baseline and bounce the ball into the opponent's field diagonally.
