About UNBEATEN
A free MMA career game built on real rankings, open maths and live simulated fights.
What UNBEATEN is
UNBEATEN is a free, browser-based MMA career game. You build a fighter from real attribute cards, then guide that fighter up the real rankings of a randomly drawn weight class, fight by fight, with every bout simulated live. The aim is the one every fighter dreams of and almost none achieve: stay unbeaten, win belts in multiple divisions and be remembered as the greatest of all time.
It started as a side project inside a larger fan app and grew into its own site because the career game was the part people kept coming back to. A new leaderboard opens every month, so the race to the top is always fresh.
Why we built it
Sports management and career games are a great way to learn a sport, but there are very few for MMA, and most of them either use made-up fighters or hide how the results are decided. We wanted a game where the opponents are the real contenders, the odds are shown in the open, and a loss feels fair because you can see exactly why the maths went the way it did.
How it is made
- Real data. Rankings, champions, records and event cards come from public sources and are refreshed regularly. Read how the simulation works for the details.
- Transparent maths. Win probabilities are computed from visible ratings, and the full rules for points, belts and GOAT status are explained in the how to play guide.
- Our own ratings. The attribute cards are original ratings based on public information such as records, finishing rates and well-known reputations. They are opinions, not official statistics.
- Tested. The game engine is run through large numbers of automated careers to check balance and to catch bugs, so that scoring, progression and the leaderboard behave consistently.
Editorial standards
The guides on this site are written by hand to explain the game and the sport, and we correct them when we find mistakes. UNBEATEN does not offer betting, wagering or real-money play, and we do not publish betting tips. Fighter information is presented factually and respectfully, and the display names players choose for the leaderboard are filtered for abusive language.
