The Unified Rules and judging criteria (ABC), October 2026

The short version

MMA allows striking and grappling, standing and on the ground. That freedom is why it has more rules than people expect. Most of them protect the fighters from the most dangerous things one human can do to another.

If it goes the distance, judges score each round, just like boxing. The winner of a round gets 10, the loser 9 or fewer.

How judges score a round

Judges look at three things, in this order. They only move down the list if the round is genuinely even on the one above.

Order	What judges look for
1st	Effective striking and grappling. Strikes that do damage. Takedowns, reversals, and submission attempts that actually threaten. Impact counts more than volume.
2nd	Effective aggressiveness. Pushing forward to finish the fight, not just walking forward.
3rd	Fighting area control. Who decided where the fight happened.

A 10–8 round means one fighter dominated, did serious damage, or both. A 10–7 is total domination and very rare.

Ways to win

• Knockout (KO). A fighter is knocked unconscious or cannot continue after a strike.
• Technical knockout (TKO). The referee, the doctor or the corner stops the fight because a fighter is not defending themselves or is too hurt to go on.
• Submission. A fighter taps, says they give up, or goes unconscious from a choke or joint lock.
• Decision. On the judges' cards: unanimous, split or majority. A draw is possible.
• Technical decision. An accidental foul stops the fight after enough rounds have been completed, and it goes to the cards.
• Disqualification. For a deliberate foul that stops the fight, or repeated fouls.

Fouls

The main ones, in plain language:

• Head-butts, eye gouging, biting, spitting and hair pulling.
• Strikes to the groin, the throat, the back of the head or the spine.
• Grabbing or bending fingers and toes (small joint manipulation).
• Kicking or kneeing the head of a grounded opponent.
• Spiking someone onto their head or neck.
• Grabbing the fence or the shorts and gloves.
• Attacking during a break or after the bell, or ignoring the referee.

A foul usually costs a point. If it is deliberate and the fighter cannot continue, it is a disqualification.

Amateur MMA is different on purpose

Amateur rules vary by state and promotion, but they are usually much safer: shorter rounds, shin pads, and often no elbows to the head, no knees to the head, or no strikes to the head on the ground at all. Ask for the rules in writing before anyone you know signs up for an amateur fight.
