The game has evolved - it's now an Olympic Sport. The rules of the modern game are easy to learn. It's played between either two players (singles) or two teams of two players (doubles). Players use the racquet to this the ball over the net into the opponent's court.
Serve, volley, backhand, forehand, deuce, 40-love, advantage - so many terms in tennis that may confuse those of you who have never played. But the aim of the game is pretty simple, hit a tennis ball over the net with your stringed racquet and inside the designated lines.
