A ball is a round object with several uses. It is used in ball games, where the play of the game follows the state of the ball as it is hit, kicked or thrown by players. Balls can also be used for simpler activities, such as catch or juggling. Balls made from hard-wearing materials are used in engineering applications to provide very low friction bearings, known as ball bearings. Black-powder weapons use stone and metal balls as projectiles.
Badminton is a racquet sport played using racquets to hit a shuttlecock across a net. Although it may be played with larger teams, the most common forms of the game are "singles" and "doubles". Badminton is often played as a casual outdoor activity in a yard or on a beach; formal games are played on a rectangular indoor court. Points are scored by striking the shuttlecock with the racquet and landing it within the other team's half of the court.
Canadian football, or simply football, is a sport in Canada in which two teams of 12 players each compete on a field 110 yards (101 m) long and 65 yards (59 m) wide, attempting to advance a pointed oval-shaped ball into the opposing team's end zone.
A tennis court is the venue where the sport of tennis is played. It is a firm rectangular surface with a low net stretched across the centre. The same surface can be used to play both doubles and singles matches. A variety of surfaces can be used to create a tennis court, each with its own characteristics which affect the playing style of the game.
Table tennis is a racket sport derived from tennis but distinguished by its playing surface being atop a stationary table, rather than the court on which players stand. Either individually or in teams of two, players take alternating turns returning a light, hollow ball over the table's net onto the opposing half of the court using small rackets until they fail to do so, which results in a point for the opponent. Play is fast, requiring quick reaction and constant attention, and is characterized by an emphasis on spin relative to other ball sports, which can heavily affect the ball's trajectory.
Futsal is a football-based game played on a hardcourt like a basketball court, smaller than a football pitch, and mainly indoors. It has similarities to five-a-side football and indoor football.
Jeu de paume, nowadays known as real tennis, (US) court tennis or courte paume, is a ball-and-court game that originated in France. It was an indoor precursor of tennis played without racquets, and so "game of the hand", though these were eventually introduced. It is a former Olympic sport, and has the oldest ongoing annual world championship in sport, first established over 250 years ago. The term also refers to the court on which the game is played and its building, which in the 17th century was sometimes converted into a theatre.
American handball, known as handball in the United States and sometimes referred to as wallball, is a sport in which players use their hands to hit a small, rubber ball against a wall such that their opponent(s) cannot do the same without the ball touching the ground twice or hitting out-of-bounds. The three versions are four-wall, three-wall and one-wall. Each version can be played either by two players (singles), three players (cutthroat) or four players (doubles), but in official tournaments, singles and doubles are the only versions played.
Palla is a traditional Tuscan ball game played in villages between Siena and Grosseto. It is also called palla EH! because players call out eh! before serving.
Pallone is the name of several traditional ball games, played in all regions of Italy, with few differences in regulations.
Pickleball is a racket or paddle sport in which two players (singles) or four players (doubles) use a smooth-faced paddle to hit a perforated, hollow plastic ball over a 34-inch-high (0.86 m) net until one side is unable to return the ball or commits a rule infraction. Pickleball is played indoors and outdoors. It was invented in 1965 as a children's backyard game in the United States, on Bainbridge Island in Washington state. In 2022, pickleball was named the official state sport of Washington.

Indoor netball is a variation of netball, played exclusively indoors, in which the playing court is surrounded on each side and overhead by a net. The net prevents the ball from leaving the court, reducing the number of playing stoppages. This gives indoor netball a faster pace than netball.
Fistball is a sport of European origin, primarily played in the German-speaking nations of Austria, Germany and Switzerland, as well as in Brazil. The objective of the game is similar to volleyball, in that teams try to hit a ball over a net, but the rules vary from volleyball in several major ways. The current men's fistball World Champions are Germany, winners of both the 2023 Men's World Championships and the fistball category at the 2022 World Games, while the current women's fistball World Champions are also Germany, after winning the 2021 Women's World Championships.
