YouFC — You vs Fighting Champions

YouFC is a physics-based UFC fight simulator where you input your physical stats and combat experience to see how you'd match up against real UFC fighters. Choose from 60+ fighters across men's and women's divisions, including legends like Mike Tyson and Conor McGregor.

Two Simulation Modes

Survival Mode: Find out how many seconds you'd last in the octagon against a professional UFC fighter before getting knocked out. Your height, weight, training, and mental toughness all factor into the calculation.

Swarm Mode: Discover how many clones of you it would take to overwhelm and defeat a UFC champion. Even untrained people can win with enough numbers — the question is how many.

The Science Behind the Score

Our User Combat Index (UCI) calculates your fighting ability using weighted multipliers for each physical and psychological attribute. The Fighter Index (FI) rates each UFC fighter based on their walk weight, championship tier, knockout wins, and submission victories. The ratio between these scores determines your survival time or the number of clones needed.

Weight Classes

Men's divisions: Heavyweight, Light Heavyweight, Middleweight, Welterweight, Lightweight, Featherweight, Bantamweight. Women's divisions: Featherweight, Bantamweight, Flyweight, Strawweight. Plus a Legends division featuring all-time greats.
