Basketball, fast-paced game played on a rectangular court, generally indoors, by two five-player teams. The primary objective of the game is to score more points than the opposition by putting a round ball through a circular band, called a rim. The two rims are at each end of the court, placed 10 ft (3.1 m) above the ground and connected to a backboard, a rectangular board that hangs from the ceiling or is supported in the air on a pole or some other structure. One of the most popular sports in the world, basketball is played by men and women of all ages and ability levels in more than 200 countries.
Some details of the game differ when it is played in different countries. Unless otherwise noted, this discussion concerns competition in the United States and Canada.
