Monopodal Sumo

From WikiDotMako

This is a game most recently played at LCA2010.

Basics:

You stand on one leg, in a pose kinda like this. There might be a display of aggression just before the game starts. There's a border/ring (maybe a chess board?) that each player plays on.

If you get knocked off the board, or you put your foot down because another player does something that forces you to, you lose.

Players grapple or 'wrassle' each other until the other player is off the board, or loses their balance.
