Before the game begins the children gather in a circle and create a consensus of how they will play. For instance, the marked field boundaries are replaced by relative boundaries with the individuals directly involved determining the boundaries. When moving to the field's periphery, an opposition player calls 'play-in', the one with the ball stops, puts it down, all other players move 3 metres away and then it is kicked towards the middle. Each team completes in full force yet the sides stay symmetrical by balancing objective competition within greater subjective cooperation. This game has been played with seventy students using 3 balls, no referees, no lines and no play stoppage.
Games are always close.
The competition is as forceful as any egotistical game can be, yet its within an overall subjective purpose of cooperation. First and foremost being that I would reverse them.
