About Octagon Lab
Octagon Lab is a free browser MMA game where you build your own UFC fighter from real ranked athletes.
Spin the reel and assign each fighter you land on to one of nine attributes — striking, KO power, grappling,
wrestling, cardio, chin, fight IQ, footwork and frame — then reveal the finished Overall.
Simulate the career to play it out fight by fight: climb the divisional rankings, earn a title shot, win
the belt and defend it, lose it and chase the comeback. Performance bonuses, crossover superfights and runs
at the all-time wins and title-defense records are all in there. Ratings are derived from public MMA rankings
and real career records, so the cards reflect how fighters actually perform.
There's a daily challenge with the same cards for everyone, a global leaderboard, and a card collection
that fills in as you pull new fighters.
Frequently asked questions
Is GoatLab free to play?
Yes. Every game runs in your browser with no download and no payment. An optional account saves your builds, and optional extras exist, but the games themselves are free.
Do I need an account?
No. You can play, post scores and take on the daily challenge as a guest. Signing in with Google just saves your players to a personal Hall of Fame and carries your progress between devices.
Where do the fighter ratings come from?
Attributes are derived from public MMA rankings and real career records — finishing rate feeds KO power, takedowns and control time feed wrestling and grappling, durability feeds chin. Retired icons appear as legend cards.
What can my fighter win?
The career simulation includes division titles and title defenses, Performance of the Night bonuses, KO and Submission of the Year honors, pound-for-pound years, and a shot at the UFC Hall of Fame.
