Similar to Sumo Fighting ‘playscheme style’, but it’s rougher and requires good balance, so perhaps not so suitable for younger children.
Draw or mark out a large’ish circle to create the arena (for information an official Sumo arena is 4.55m in diameter). Players compete, starting off at opposite sides of the ring. Players fight standing on one leg and arms folded at all times, hopping around attempting to unbalance their opponent. A player is out as soon as they either put both feet down, fall down or get forced out the ring.
For this type of game to keep things friendly, allow players to decide their own opponents and pair up.
