The players form into two teams, one team, the defenders, form a circle by holding hands and facing outwards. They are the castle. One of the castle may stand in the middle of the circle. The other team, the attackers, surround the fort and try to kick the football in the circle (either through the legs or over the head). The team member in the middle of the circle may catch it and stop it hitting the ground. Every time the ball touches the ground the attackers have captured the castle and the teams switch sides.
