Measurements and time limits discussed in this section often vary among tournaments and organizations; international and NBA rules are used in this section.
The object of the game is to outscore one's opponents by throwing the ball through the opponents' basket from above while preventing the opponents from doing so on their own. An attempt to score in this way is called a shot. A successful shot is worth two points or three points if it is taken from beyond the three-point arc which is 6.25 meters from the basket in international games and 23 feet 9 inches in NBA games. A one-point shot can be earned when shooting from the foul line after a foul is made.
Games are played in four quarters of 10 FIBA or 12 minutes NBA. College games use two 20 minute halves, while high school varsity games use 8 minute quarters. 15 minutes are allowed for a half time break under FIBA, NBA, and NCAA rules and 10 minutes in high school. Overtime periods are five minutes in length except for high school which is four minutes in length. Teams exchange baskets for the second half. The time allowed is actual playing time; the clock is stopped while the play is not active. Therefore, games generally take much longer to complete than the allotted game time, typically about two hours.
Five players from each team may be on the court at one time. Substitutions are unlimited but can only be done when play is stopped. Teams also have a coach, who oversees the development and strategies of the team, and other team personnel such as assistant coaches, managers, statisticians, doctors and trainers.
For both men's and women's teams, a standard uniform consists of a pair of shorts and a jersey with a clearly visible number, unique within the team, printed on both the front and back. Players wear high top sneakers that provide extra ankle support. Typically, team names, players' names and, outside of North America, sponsors are printed on the uniforms. A limited number of time outs and clock stoppages requested by a coach or sometimes mandated in the NBA for a short meeting with the players are allowed. They generally last no longer than one minute 100 seconds in the NBA unless, for televised games, a commercial break is needed.
The game is controlled by the officials consisting of the referee referred to as crew chief in the NBA, one or two umpires referred to as referees in the NBA and the table officials. For college, the NBA, and many high schools, there are a total of three referees on the court. The table officials are responsible for keeping track of each team scoring, timekeeping and individual and team fouls, player substitutions, team possession arrow, and the shot clock.
