In early 2025, I kept coming across football-themed XOX sites and thought — why isn't there an MMA version of this? I'm a developer and an MMA fan, so I decided to build it myself. What started as a simple tic-tac-toe game with UFC fighters has grown into a full platform with multiple game modes, a fighter database with 2500+ athletes, real-time multiplayer, and players from around the world. MMA XOX launched in August 2025 and has been growing ever since.
MMA XOX is an independent project built and maintained by a single developer. There's no team, no funding, no ads — just a passion project that turned into something real. Every feature you see was designed, coded, and shipped solo. Fighter data is scraped and updated weekly through an automated pipeline. The site is free to play and always will be.
To build the best free MMA gaming experience on the internet. One that MMA fans actually want to use — with real fighter data, real game modes, and real competition. No fluff, no paywalls, no ads.
No ads, no paywalls, no pay-to-win. MMA XOX is and will remain completely free to play.
Fighter stats are pulled from real sources and updated every week automatically.
Built for MMA fans, by an MMA fan. Feedback directly shapes what gets built next.
No investors, no corporate agenda. Just a developer who wanted to build something cool.
Pick a game mode and jump in — no account required for most modes. If you want to climb the ranked leaderboard or challenge friends, create a free account in seconds.
