## Rules

Rumble on the Rock's rules are based upon the Unified Rules of Mixed Martial Arts that were originally established by the New Jersey State Athletic Control Board and modified by the Nevada State Athletic Commission. These rules have been adopted across the US in other states that regulate mixed martial arts. As a result, they have become the standard de facto set of rules for professional mixed martial arts across the US and for cage-based MMA worldwide.
All bouts are contested over three, five-minute rounds, with the exception of five-round championship bouts. There is a one-minute rest period in-between rounds. As per the Unified Rules of MMA, Rumble on the Rock only allows competitors to fight in approved shorts, without shoes or any other sort of foot padding. Fighters must use approved light gloves (4-6 ounces) that allow fingers to grab. The referee has the right to stop the fighters and stand them up if they reach a stalemate on the ground (where neither are in a dominant position nor working toward one) after a verbal warning.

### Match outcome

Matches usually end via:
* Submission: a fighter taps on the mat or his opponent three times (or more) or verbally submits.
* Knockout: a fighter falls from a legal blow and is either unconscious or unable to immediately continue.
* Technical Knockout: stoppage of the fight by the referee if it is determined a fighter cannot "intelligently defend" himself or by ringside doctor due to injury.
* Judges' Decision: Depending on scoring, a match may end as:
** unanimous decision (all three judges score a win for one fighter),
** split decision (two judges score a win for one fighter with the third for the other),
** majority decision (two judges score a win for one fighter with one for a draw),
** unanimous draw (all three judges score a draw),
** majority draw (two judges score a draw).
** split draw (the total points for each fighter is equal)
A fight can also end in a technical decision, technical draw, disqualification, forfeit or no contest.

### Judging criteria

The ten-point must system is used for all Rumble on the Rock bouts; three judges score each round and the winner of each receives ten points, the loser nine points or less. If the round is even, both fighters receive ten points. The decision is announced at the end of the match but the judge's scorecards are not announced.
