These are basic rules and information that will prepare players and also help their participation overall.

The tennis scoring system works in a way in which players accumulate points, games, and sets.

  • Tennis points are counted as 0, 15, 30, and 40.
  • The first player to win 4 points wins a game, and the first player to win 6 games wins a set.
  • In order to win the match, a player must win 2 sets.

There are multiple ways a point can be scored.

  • An unreturnable ball (ball bounces twice);
  • Double fault;
  • Ace (unreturnable serve);
  • Ball hit out of bounds (the lines count as in);
  • Ball hit into the net.

Positioning When You Serve During the Singles Game

  • The server must serve diagonally into the service box across the court.
  • The server must serve from a stationary position behind the baseline, between the center mark and sideline — the singles sideline for singles and the doubles sideline for doubles.
  • The server gets two chances to hit a good serve. A missed serve is called a “fault”. The serve is a fault if the server swings and misses the ball. The server may stop the serve by catching the ball and starting over.
  • If a served ball touches the net but lands in, it is replayed because the net interfered.

In Doubles:

  • The server is only allowed to serve from behind the baseline of alternate halves, and he must start from the right side of the court.
  • The server’s foot is not allowed to touch either the court or the baseline, outside the imaginary extension of the sideline. 
  • The net player can stand anywhere they choose when their partner is serving, and this includes on their partner’s side of the court.
