Glass Jaw — the online MMA career sim

Create a fighter and join The League: one shared world where every rival on the card is managed by a real person. Fights are booked and fought in real time, and the rankings, callouts, camps, and title pictures move whether or not you are online.

Climb from the amateur circuit through the regionals to the World Fighting League. Train between bouts, learn techniques, pick a game plan and an aggression level, then follow every round of play-by-play to a knockout, a submission, or the judges’ scorecards. Join or charter a fight camp, recruit, and build a stable of fighters.

Play in your browser right here, or get the Glass Jaw app for iPhone and Android — same account, same world. A guest account is created the moment you build a fighter, so there is nothing to sign up for first.
