The fight should take place on gymnastics mats or another soft floor (sand, grass, etc.)
Two players are standing on the fighting area, facing each other. They fold their arms on their back.
The objective of the fight is to move the other player out of the playing/fighting field. Only pushing (with the chest or the shoulder) is allowed, but not using the hands, kicking with the feet or the head, etc.
- Rugger scrums: this game follows the same basic idea, but is played with two teams opposing each other
