Organization:

Area: 25y x 20y

The central attacker starts with the ball and passes it to one of their teammates to start the 3v3.

The attackers score on the two small goals, and the defenders score by dribbling the ball through two gates in the corners of the endline.

When the ball goes over the sideline, dribble or pass the ball back in.

Play is over when a goal is scored, or the ball goes over the end line.

Switch sides after each turn, or switch sides after certain amount of time. 

Game:

Keep track of goals scored by trio, or create two large teams and keep track of score that way. Which team scores the most goals.
