When one team reaches the target score, the other team gets the ball with a 3-second clock. If that team scores, the score gets added to the target score.
Example. Target score is 80. Actual score is 78-75. Team A scores 2, the score is now 80-75. Team B gets the ball with a three-second clock. Team B successfully jacks up a three. The score is now 80-78, the target score is 83, Team A has the ball.
Or Team B misses, Team A wins, final score is 80-75.
