21 or more with a two or three-point shot, the player must first hit a free throw successfully. If he does so, he then shoots a 3-pointer to win the game. If he misses the free throw, he does not lose any points, and the game continues. If he makes the free throw but misses the 3-pointer, his score is reset to a lower value (e.g. 13, as above) and the game continues. Players on 19, shooting at the foul line, must hit rim or be forced back to 11. (This prevents a player on 19 from simply slamming the ball off the backboard to himself, thereby regaining possession without having to rebound normally. If the score is tied at 19, one of the tied players must first reach 21, then score 2 additional points to win. Once you get to 21 you shoot one free throw to win or go back down to 11. Formal use Twenty-one is frequently used in physical education classes and by basketball team coaches as skill development. Because only one player is on offense at any given time against several defenders, quickness and shooting skills are essential to successful play.
