when is the only time a jump ball is used?
31 december 1987
the center jump ball that was used to restart a game after every successful field goal was eliminated in 1938, in favor of the ball being given to the non-scoring team from behind the end line where the goal was scored, in order to make play more continuous. the jump ball was still used to start the game and every period, and to restart the game after a held ball. however, the nba stopped using the jump ball to start the second through fourth quarters in 1975, instead using a quarter-possession system where the loser of the jump ball takes the ball from the other end to start the second and third periods, while the winner of that jump ball takes the ball to start the fourth period from the other end of the court.
rules of basketball
in basketball, if the score is tied at the end of regulation play, the teams play multiple five-minute overtime periods until a winner is decided. in levels below collegiate/olympic play, an overtime period is half the length of a standard quarter, i.e., four minutes for high school varsity. 3x3 (originally fiba 33), a formalized version of the halfcourt three-on-three game, uses an untimed overtime (the former fiba 33 rules called for two-minute periods). the alternating possession rule is used to start all overtime periods under international rules for full-court basketball, while a jump ball is used under high school and ncaa rules, with the arrow reset based on the results of the jump ball to start each overtime. the (women's) national basketball association, which use a quarter-possession rule to start periods after the opening jump, also use a jump ball. in 3x3, whose current rules do not allow for a jump ball at any time in the game, the first possession in overtime is based on the result of a pregame coin toss; the winner of the toss can choose to take possession of the ball either at the start of the game or at the start of a potential overtime. the entire overtime period is played; there is no sudden-death provision. the only exception is in 3x3, in which the game ends once either team has scored 2 points in overtime, with baskets made from behind the "three-point" arc worth 2 points and all other successful shots worth 1 point. all counts of personal fouls against players are carried over for the purpose of disqualifying players (except in 3x3, where individual foul counts are not kept, but team foul counts are). if the score remains tied after an overtime period, this procedure is repeated.
