As submission wrestling is based on Brazilian Jiu Jitsu, you'll notice that the two sports share very similar competition rules. The person or the team could be disqualified from the contest, if these rules are not observed. Winning in submission wrestling is simple -- you only have to make your challenger either say he surrenders or get him to tap the mat. If neither wrestler surrenders and the referee doesn't end the fight for some reason,, the judges will decide on who is the winner of the match. If the game is a tie, there match will go on overtime, which lasts for one minute. After the 60-second overtime is up and still nobody scores, the winner is decided through sudden death, which means that whoever scores first wins.
