About 25-0
An independent fan project · 331 fighters · 840 rated cards
What this is
25-0 is a free MMA draft game. You spin a year and a weight class, get five fighters from that era, and take one attribute from one of them. Do that eight times and you have a composite fighter — someone else's boxing, someone else's wrestling, a chin borrowed from a third. Then you pick a division and simulate 25 fights to see whether the thing you built can retire undefeated.
There is no sign-up, no account and no paywall. A run lives in your browser tab and disappears when you close it. The only thing that persists is a share link, and that encodes the result into the URL itself rather than into any database.
Where the ratings come from
Ratings combine values from a compiled fighter dataset with editorial judgement. They are one person's assessment, not official statistics.
Fighters are rated per era, not once. Most appear across several of the seven editions the dataset covers, so a 2012 spin and a 2025 spin can hand you two very different versions of the same person. A fighter who competed at more than one weight has a separate card per division, because the ratings differ.
Two different Overalls
The Overall on a fighter's card is an editorial score. The Overall you see while drafting and simulating is a straight average of the eight attributes you picked. They are calculated differently on purpose: one describes a real fighter, the other describes the composite you assembled. A build has no card, so it cannot have a card rating.
Editorial standards
Write-ups are the editor's own summaries of each fighter's career. They are not independently fact-checked, so treat specific dates and results as unverified. Write-ups focus on fights and results. Injuries and suspensions are mentioned only where they affected a fighter's career.
Ratings are my own estimates, made with AI assistance. They are opinion, unofficial, and not a measure of anyone's real-world ability. Guides show the date they were last updated, and each fighter page names the division and edition its numbers come from.
Who makes it
25-0 is built and maintained by Haaris A, as an independent fan project, with no promotion, publisher or sponsor behind it. It was inspired by 38-0.app and 84-0.com, which are not affiliated with this project.
Corrections are welcome, and ratings arguments especially. If a fighter is scored wrong, get in touch — the dataset changes when someone makes a good case.
