You just watched a 25-minute war in the cage. The fighter threw 40 strikes, landed a takedown in round three, and had the crowd on their feet. The announcer reads the scorecards, but the guy lost. The commentators sound confused. The losing fighter looks stunned. The arena boos.
It happens at a majority of UFC events, and it sends thousands of fans scrambling for answers on Google every single week. The frustrating part isn’t just the result; rather, it’s not knowing why it happened or whether the judges were even watching the same fight as the rest of the audience.
But once you understand how UFC scoring actually works, the answers become as clear as day. And the whole point system hinges on four criteria: the priority order judges are supposed to follow, and where the system breaks down. After which, you’ll be able to calculate and score rounds by yourself in real time.
As this article further progresses, it covers: the 10-point must system, the 4 judging criteria in the order they’re supposed to be applied and what a 10-8 round actually requires.
What Happens When a UFC Fight Goes to the Scorecards?
Not every UFC fight ends by knockout or submission. When neither fighter finishes the other, the fight goes the full distance and three cageside judges decide the winner.
Three judges sit at three different positions around the octagon. Each one scores independently. They don’t discuss rounds between themselves. When the fight ends, each judge has a total score for each fighter, and those individual totals determine who gets the win in that particular round.
Here is an example of how a scorecards look:
One thing fans often get wrong: judges don’t score the overall fight. They score each round separately. A fighter who loses the first two rounds 10-9, then completely dominates the third round, still loses on the scorecards. Because the third round is just one round, worth the same as the first two. Thus, there’s no “momentum” credit, no narrative weight. Round 1 and Round 5 carry identical value.
Once all rounds are scored, the results produce one of four outcomes:
| Decision Type | What It Means |
| Unanimous Decision | All 3 judges scored for the same fighter |
| Split Decision | 2 judges for Fighter A, 1 judge for Fighter B |
| Majority Decision | 2 judges for Fighter A, 1 judge scored it a draw |
| Draw | Scorecards are tied. Fight has no winner |
What Is the 10-Point Must System in MMA?
The 10-point must system was borrowed from boxing. And it was formally adopted for MMA under the Unified Rules of Mixed Martial Arts, established by the New Jersey State Athletic Control Board in 2000. It’s the scoring foundation used by the UFC and nearly every major North American MMA promotion.
The rule is simple in principle: the winner of each round must receive 10 points. The loser receives 9 or fewer. Every round produces a score, and those scores stack up over the course of the fight.
There are four possible scores a judge can give for any single round:
10-9:
This is what roughly 85% of all scored rounds receive. It means one fighter won the round, clearly enough that the judge could identify a winner. But the loser was still competitive. A round where one fighter lands better shots, gets a takedown, or controls more of the action gets a 10-9. The losing fighter was still in the fight.
10-8:
A 10-8 round is not a reward for an exciting performance. Per the ABC’s updated guidance, a 10-8 requires that the winning fighter caused meaningful damage or maintained significant positional dominance. Moreover, limited the other fighter’s offence enough to end the round in a diminished state.
If you watched the round and thought “the loser is going to be fine for the next round,” it’s almost certainly a 10-9. If you watched it and thought “that fighter just took real damage that changes this fight,” it might be a 10-8.
This is where many judges have historically underused the score. A 10-8 that isn’t awarded when it should be can flip a close fight. If a fighter dominates round two, but the judge gives it 10-9 instead of 10-8, and the other fighter wins rounds one and three 10-9, the dominant fighter loses the fight 29-28 instead of winning it 29-28.
10-7:
A 10-7 round means one fighter was so thoroughly dominated that you’re almost surprised the referee didn’t step in. These are exceptionally rare. Judge Mark Collett awarded a 10-7 to Khamzat Chimaev in his UFC debut against John Phillips. A round where Chimaev controlled, damaged, and nearly knocked out his opponent for almost the entire five minutes with virtually no meaningful response.
10-10:
A 10-10 means neither fighter had any meaningful advantage. In theory, this is supposed to be used when a round was truly too close to call in any direction. In practice, some judges use it too liberally as a way to avoid making a decision. A genuine 10-10 round is rare.
The 4 Official UFC Judging Criteria
This is the section most fans are not aware of, and it remains a pivotal one.
Judges don’t score rounds on gut feel or overall impression. The Unified Rules of MMA give them four specific criteria, applied in priority order, like a decision tree. If you can determine a winner using criterion #1, you’re done. You only move to criterion #2 if #1 is genuinely even, and so on.
Understanding this order is what separates informed fans from frustrated ones.
Priority #1: Effective Striking AND Effective Grappling
These two are evaluated together, with equal weight, and where rounds should be decided, the majority of the time.
Effective striking is not about counting punches. It’s about the impact. A short right hand that staggers an opponent outweighs 15 jabs that move nobody. The UFC’s official stats track “significant strikes,” which is a useful reference, but judges are specifically instructed that the effect of strikes matters more than the volume. A fighter can throw twice as many punches and still lose the striking criterion if the other fighter’s shots are doing more damage.
Effective grappling covers takedowns that lead somewhere, submission attempts that force real defensive reactions, guard passes, back takes, and dominant positions that produce damage or near-finishes. A takedown that lands and immediately gets reversed or stood up with no offence attached carries minimal weight. Taking someone down and landing ground and pound from top position that’s effective grappling.
The most common fan mistake: assuming that whoever threw more strikes or scored more takedowns won the round. Volume without effect is not Plan A dominance. If Fighter A throws 40 strikes that mostly miss or glance, and Fighter B throws 18 that all land clean and stagger Fighter A twice, Fighter B is winning the striking criterion despite throwing less than half as many shots.
Priority #2: Effective Aggressiveness
Judges only move to this criterion if Plan A, effective striking and grappling, is genuinely equal between both fighters after the full round.
Effective aggressiveness means proactively pursuing the finish. Walking forward with your hands up, touching your opponent, and retreating is not effective aggressiveness. Throwing with intent, pressing for takedowns, and hunting for submissions is.
One misconception worth clearing up: counter-striking does not automatically mean losing aggressiveness. If a counter-puncher is landing more damaging shots, they’re winning Plan A anyway. A fighter who moves backwards but cracks their opponent with a clean counter that rocks them is not “losing” on any criterion; they’re winning Plan A outright.
Priority #3: Fighting Area Control / Octagon Control
This is the last resort, applied only when Plans A and B are both even. Which, in a genuine 25-minute fight, is extremely rare if judges are applying the criteria correctly.
Octagon control means dictating the pace, position, and location of the fight. The fighter who decides where the action happens against the cage, in the centre, standing, or on the ground, is demonstrating cage control.
Here’s the critical point, and the one most responsible for bad decisions: octagon control is the least important criterion, not the most. A fighter pinned against the cage who is landing more effective strikes is winning Plan A, regardless of “control.” They are winning the fight even from what looks like a defensive position. Many of the most controversial UFC decisions in history came from judges over-weighting this criterion. And giving credit for cage control when the fighter being pushed against the fence was actually doing more damage.
Judges are instructed to value what a position leads to, not just the position itself.
Point Deductions and Disqualifications
Most fans know that fouls exist, but don’t fully understand how they affect scorecards.
Referees, not judges, issue warnings and deductions. A first offence almost always gets a verbal warning. A second offence, or a severe foul, even on the first occurrence, results in a 1-point deduction. In a close fight, losing one point is the equivalent of giving your opponent a free round. Turning a 10-9 round win into a 9-10 round loss, which can flip the entire script.
The fouls that most commonly result in deductions are eye pokes, groin strikes, strikes to the back of the head, and grabbing the fence for positional advantage.
Disqualification (DQ): A fighter who commits intentional or repeated severe fouls loses the fight by DQ. These are rare. The most famous example in UFC history is Jon Jones vs. Matt Hamill at UFC 107 in 2009. The only official loss on Jones’s record. Jones landed repeated 12-to-6 elbow strikes (downward vertical elbows, banned under the Unified Rules) on a downed Hamill and was disqualified despite dominating the fight.
Technical Decision: If an accidental foul, most commonly a head clash, stops a fight after half the scheduled rounds have been completed. The fight goes to the scorecards for whoever was winning at the time. If the stoppage happens before half the rounds are finished, the fight is declared a no-contest.
