's Ones Basketball League is a one-on-one basketball league. Features of one-on-one basketball which may differ from a normal game include "make it take it", where making a shot is rewarded with possession of the ball instead of giving it to the opposing team. Also, when there is a change of possession, the player who just got the ball has to take the ball back behind the free throw line. Often times in one-on-one a player is expected to "check" the ball, meaning to start a possession by passing it to the opposing defender, who then passes it back.
