Sumo

Two wrestlers crouch at opposite sides of the circular ring and touch the ground with both fists before starting.

On the referee's signal, both wrestlers charge forward and grapple, trying to push or throw each other off balance.

A wrestler loses the bout the moment any part of their body other than the soles of their feet touches the ground.

A wrestler also loses if they are forced to step outside the boundary of the ring.

Matches are usually decided in a single bout, and the winner faces the next challenger.
