There are four defenders against four attackers in white. The trainer has the ball and passes a pass to one of the attackers. The defender opposing the player receiving the ball must first touch the back line before they may participate in the game on the other side. As soon as the attackers receive the ball, they try to score as quickly as possible. The goal of the defenders is to pick up the dribbler to force or slow down a bad pass so the other defender can recover.
