Small field, lots of shots and goals, shoot before the center line! The game starts with a goalkeeper's opening. Only one player from the defending team is allowed to press in the attacking team's half, so the situation is 2v1 (3v1 when the goalkeeper is involved). The attacking team must shoot from their own area before the center line! If the defender manages to steal the ball, the other initially defending team players can join the attack, and the situation is played normally as 3v3 until the end.
The attacking team can be changed, for example, by having one team attack consecutively as long as they succeed in scoring. You can also change after each situation, or the coach can pass a new ball into play to the goalkeeper, from whose side a new situation starts. The goal is to keep the game fast-paced.
