In a Brawl mode the only way to win is by deflating the opponents' energy bars to zero, and there are no referees or any counts.
When the One Fall option is enabled, characters cannot perform chokes and eye gouges. But if the referee gets knocked down, these attacks will be enabled until he recovers. However, the match can not end until the referee is able to count pin attempts or ring outs. If the referee is knocked down too many times, he will walk out of the ring. The match will then continue under Brawl rules.
Applying certain holds to opponents which have no stamina will result in them giving up. This will not work in the Royal Rumble match.
