Depending on how many players there are you can use the full 6/9 meters or just a part of it.
The defending players will hold hands two by two (so if there are 6 players, there will be 3 groups of 2).
The attacking players will pass the ball around between themselves and around the area trying to "destabilise" the defence and find a gap so they can run in and touch down with the ball in the area.
If the 2 groups of the defending players touch the attacker, the point does not count.
if only 1 of the groups of the defending players touch the attacker, the point counts.
If none of the groups of the defending players touch the attacker, it counts 2 points.
The goal is to get to 8/10 points (depending on how many 2 points they score) and then swap.
If there's few players, shorten the court and if there's an uneven number, the defence stays with one less.
