Most "who would win" debates in MMA go in circles because everyone weighs the stats differently. Our UFC fight simulator settles them with a consistent model — the same way a matchmaker or a betting market does, just transparent. Here is exactly what the engine looks at, and why style matchups matter more than a single overall rating.
The four things that actually decide a fight
Every fighter in our database carries 15+ real attributes, but the engine groups them into four pillars that genuinely swing fights:
1. Striking. Punch and kick power, speed, accuracy and defense. This is your offense on the feet — the ability to hurt someone and not get hurt back. High striking wins the rounds that stay standing.
2. Grappling & wrestling. Takedowns, takedown defense, top control and submissions. This is the "where does the fight happen" stat. A great wrestler can erase a great striker by simply refusing to let the fight stay where the striker is dangerous.
3. Durability. Chin and cardio together. Can you take a shot, and can you keep your output up in the championship rounds? Durability is what lets a fighter survive a bad moment and win anyway — read more in our toughest chins breakdown.
4. Fight IQ. The intangible — pacing, reads, adjustments and shot selection. Two fighters with identical physical tools are not equal if one consistently makes the smarter decision.
Why style beats rating
Here is the key idea: the engine compares your groups against your opponent's, not just a single number. A fighter rated 88 overall who is all striking can lose to an 84 who happens to be a wrestling nightmare for them — because the matchup, not the rating, decides the night. That is why a slight favorite on paper is sometimes a live underdog once you look at the styles.
The engine turns those group comparisons into a win probability, then rolls the fight out: a clear edge usually means a finish, a close one tends to go to the cards, and a live underdog with power always has a puncher's chance.
Try it on a real matchup
The fastest way to understand it is to run one. Open the fight simulator, pick a striker against a wrestler, and watch how the predicted method and round shift when you change the matchup. Then take it further: play UFC Matchmaker to book a fighter up the rankings, or live a whole career from prospect to champion in the MMA Career Simulator.
