Our UFC card builder lets you create any custom fight card from the full active roster — then run every matchup through the same combat engine that powers MMAFightSim.com. Build it yourself, or use the one-click UFC fight card generator — hit Generate Random Card for an instant lineup, or Dream Card to make your own UFC card of cross-division superfights. Book cross-division and dream matchups that could never happen in real life, fill up to 5 slots, then hit simulate and watch your card play out as a live Fight Night — a building Arena Energy meter, crowd reactions to every finish and upset, and a verdict on whether you booked an instant classic or emptied the building. As you build, a live Card Hype meter and projected buyrate react to every pick, rotating booking goals challenge you to stack a real event, and your card earns an Event Score out of 100 based on the hype you built and how the fights actually delivered. Free UFC card simulator & generator — no account needed.
Click any corner slot to open the fighter browser. Use the division tabs (LW, HW, MW…) to browse by weight class, or search by name. Once you fill one corner, the other automatically locks to the same division — just like real UFC matchmaking.
Build your Main Event (5 rounds), Co-Main, and 3 Main Card bouts, then hit Simulate Fight Card to run all results at once.
Our UFC card simulator runs each fight through a weighted algorithm using 15+ real combat stats — striking power, grappling, stamina, chin, fight IQ, reach and footwork. It calculates win probability and determines the finish method (KO, Sub, or Decision).
Want deeper breakdowns? The full UFC simulator adds round-by-round AI commentary and tactical analysis on every matchup.
What is a UFC card builder?
A UFC card builder (also called a UFC card creator or matchmaker tool) lets fans arrange their own fight cards with real fighters — like being Dana White for a night. Ours also simulates every result with win probabilities.
How is my card scored?
As you build, a live Card Hype meter rates your star power, competitiveness and division variety, with a projected buyrate. After you simulate, your card gets an Event Score out of 100 that combines that hype with how the fights actually delivered — finishes, upsets and a Fight of the Night — plus bonus for the rotating booking goals you hit. Beat your best score.
What are the card challenges?
The builder has 8 themed challenges — Title Night, Stacked Card, Champ vs Champ, All-Action Night, Women's Showcase, Legends Card and more. Each has requirements that tick off live as you build, plus an Event Score target: hit it to earn 1 star, beat it by more for 2 or 3 stars. Your best stars are saved per challenge, so there's always a goal to chase and 24 stars to collect — not just random fights.
Can I simulate the same card again?
Yes — hit Resimulate and the engine re-rolls with fresh randomness. Different finishes are possible every time.
Can it generate a random card for me?
Yes. Hit Generate Random Card and the UFC fight card generator instantly fills all five slots with competitive, division-accurate matchups — refresh as many times as you like, then simulate.
