MMA rules and scoring decide every fight that doesn’t end early, but most fans only see the final scorecards. This guide explains how judges score rounds under the Unified Rules of MMA used by the UFC, what they reward, which fouls cost points, and how ONE Championship, which has a big following in the Philippines, does things differently. For results, fight previews, and news on Filipino fighters, follow our UFC and MMA coverage.

How are MMA fights scored?
Three judges sit cageside and score each round separately using the 10-point must system. The winner of a round receives 10 points and the loser usually receives 9. MMA uses the same 10-point must system as boxing, explained in our boxing scoring guide, but MMA judges also reward grappling, not just striking.
If the fight isn’t finished, each judge adds up their round scores, and the fighter who wins on at least two of the three cards wins the decision. Decisions can be unanimous, split, or majority, and draws are possible.
How many rounds are in a UFC fight?
Each round lasts five minutes, with a one-minute rest between rounds. Most UFC fights are scheduled for three rounds, while title fights and main events go five rounds, as covered in our guide to how the UFC works.
MMA judging criteria under the Unified Rules
The Unified Rules of MMA, maintained by the Association of Boxing Commissions (ABC), give judges three criteria in strict order. Judges only move to the next one if the fighters are completely even on the one before.
| Order | Criterion | What it means |
|---|---|---|
| 1 | Effective striking and grappling | Legal strikes and grappling that have an impact, such as damage, takedowns, and near submissions |
| 2 | Effective aggressiveness | Pressing to finish the fight with an effective result, not just moving forward |
| 3 | Fighting area control | Dictating where and how the fight takes place |
Effective striking and grappling decides almost every round. Judges weigh striking more heavily if most of a round is on the feet, and grappling more heavily if most of it is on the mat.
Key takeaway
Under the Unified Rules, holding a dominant position or walking forward does not win a round by itself. Judges reward the effect of a fighter’s offense, not how busy or aggressive they look.
What is a 10-8 round in MMA?
A 10-8 round is scored when one fighter wins a round by a large margin, not just a clear one. Judges look at three factors: damage, dominance, and duration.
In 2025, the ABC clarified that a 10-8 round must include significant damage from effective striking or grappling, with dominance and duration supporting the score. Unlike in boxing, a knockdown does not automatically make a round 10-8.
| Round score | When judges use it |
|---|---|
| 10-9 | One fighter wins the round |
| 10-8 | One fighter wins by a large margin, including significant damage |
| 10-7 | One fighter overwhelms the opponent so completely that a stoppage could have been called; very rare |
| 10-10 | Allowed, but extremely rare in practice |
How do MMA fights end?
Most MMA fights don’t reach the judges. A fight can end in several ways, each with its own rules.
| Result | How it happens |
|---|---|
| Knockout (KO) | A fighter is knocked unconscious by a legal strike |
| Technical knockout (TKO) | The referee, ringside doctor, or a fighter’s corner stops the fight |
| Submission | A fighter taps out, verbally submits, or is choked unconscious |
| Decision | The judges’ scorecards decide a fight that goes the distance |
| Disqualification | A fighter commits a serious or repeated foul |
| No contest | The fight ends without a result, such as after an accidental foul early in the bout |
Submissions come in a few forms. A fighter can tap the opponent or the mat, submit verbally, or lose by technical submission when the referee stops the fight because the fighter has been choked unconscious or is at risk of serious injury in a hold.
Common MMA fouls
The Unified Rules list fouls that can lead to warnings, point deductions, or disqualification. The referee decides how serious each foul is and whether to take a point away from the offending fighter’s score for that round.
| Foul | Examples |
|---|---|
| Strikes to illegal targets | Groin, throat, spine, and the back of the head |
| Eye attacks | Eye pokes and gouging |
| Illegal strikes to a grounded fighter | Kicks or knees to the head of a grounded opponent |
| Dangerous grappling | Small joint manipulation and spiking an opponent onto the head or neck |
| Unsportsmanlike tactics | Headbutts, biting, hair pulling, fish hooking, and clawing or pinching the skin |
Accidental fouls
Not every foul is deliberate. A fighter hit by an accidental low blow is given up to five minutes to recover, and an accidental eye poke usually leads to a pause and a check from the ringside doctor.
If an accidental foul leaves a fighter unable to continue, the result depends on how far the fight has gone. Early in the bout it is usually ruled a no contest, while later it can go to the judges’ scorecards as a technical decision.
The referee’s role
The referee runs the fight inside the cage, enforcing the rules, warning fighters, and deducting points for fouls. The referee also decides when to stop the fight, which is why many TKOs come from a referee stepping in to protect a fighter who can no longer defend themselves.
Recent rule changes
Two long-debated rules changed on November 1, 2024. The ABC removed the ban on the “12-6” elbow, a straight-down elbow strike, and the UFC applied the new rule from its next event on November 2.
The ABC also redefined a grounded fighter as one with any part of the body other than the hands or feet touching the canvas. Putting a hand down no longer protects a fighter from kicks and knees to the head. Each local commission decides whether to adopt the rule changes.
How ONE Championship rules differ
ONE Championship uses its own Global Rule Set instead of the Unified Rules that form the basis of UFC rules. The biggest difference is judging: ONE scores the whole fight rather than each round, so a fighter who loses early rounds can still win with a dominant finish.
ONE judges look first at near-knockouts and near-submissions, then at damage. ONE also allows knees to the head of a grounded opponent, which the Unified Rules ban, although it banned soccer kicks in 2016.
| Rule | Unified Rules (UFC) | ONE Championship |
|---|---|---|
| Judging | Round by round, 10-point must | The whole fight |
| Knees to a grounded opponent’s head | Illegal | Legal |
| Soccer kicks | Illegal | Illegal since 2016 |
| Weight checks | Weigh-in, usually the day before | Weigh-in plus a hydration test during fight week |
ONE’s hydration test uses a urine sample to check that fighters are not cutting weight through extreme dehydration. A fighter must pass it to be allowed to weigh in.
What the rules mean for bettors
Rules and scoring shape how fights end, which affects method-of-victory and round markets. Because ONE judges the whole fight, a late surge counts for more than it would under round-by-round scoring. Our MMA betting guide explains how these markets work and how results are settled. Betting is for adults aged 21 and over.
