Tennis is a game played with two opposing players (singles) or pairs of players (doubles) using tautly strung rackets to hit a ball of specified size, weight, and bounce over a net on a rectangular court. The ball can bounce once but only on the opposite side of the person who hit it. To get a point, you need your opponent to hit the ball out of the court without it bouncing, have the ball bounce on their side twice in a row, have the opponent hit the ball making it bounce on their side, or make the ball bounce on their side then go out of court. Tennis is an entertaining game of endurance, one slip up and the opponent may win.
