Tennis is a fast-paced racket sport played between two opponents (singles) or two teams of two players each (doubles). The game takes place on a rectangular court divided by a net, with players using rackets to hit a ball back and forth. The objective is to score points by landing the ball within the opponent's court boundaries in a way that prevents them from returning it. Matches consist of sets, which are further divided into games. Players must employ strategy, agility, and precision, mastering serves, volleys, and groundstrokes to outmaneuver their rivals. Tennis can be played on various surfaces, including grass, clay, and hard courts, each affecting gameplay differently. Popular worldwide, the sport features major tournaments like Wimbledon, the US Open, and the Australian Open.
