Tennis a team, duo, and individual sport where opponents use a racquet to hit a ball across a net. Points are scored when someone hits outside the indicated court, the ball bounces twice, the ball is hit into the net, or when the ball is not returned. Tennis is scored by points, games, then sets. A person must score 4 points to win a game, 6 games to win a set, and 2 sets to win the match. If you are interested in playing tennis, you can join a program below.
