The popular game of tennis, originally called “lawn tennis,” was first developed in Great Britain in the 1860's. The object of this game is for players to gain points by hitting a tennis ball over a net, into the opponent's side of the court, using a tennis racket.
Before the ball hits the floor, however, the opponent can hit it back. The ball can also bounce once before the opponent must return it. In this game, players typically compete to win the best of three to five sets. Each set is made up of at least six games. To win a set, a player must win six games, leading with two games at least.
The scoring system in tennis uses unique terms. In each game, the score starts at “love,” or zero, and advances to 15, 30, 40 and “game.” If players tie at 40-40, called a “deuce,”they must continue the game until one player is ahead by two points.
