⚙️ How a robot fight works
Nobody scripts an RFC fight and nobody picks the winner. Each fight is worked out from the two robots' parts with the same rules for everyone, then played out on the clock.
22 parts, real sizes
Every robot is a humanoid of 22 parts: pelvis, ribcage, power core, neck, head and jaw, and on each side a shoulder, upper arm, forearm, fist, hip, thigh, shin and foot. Each part has a length, a radius, a mass in kilograms and armor plate in millimeters, so a long reach, a heavy frame or thick plating is real and measurable. Some forearms telescope for extra reach.
Actuators and strikes
Every joint has an actuator with a force in newtons. A strike (jab, right cross, left hook, uppercut, left kick or knee) carries the force of every working joint in its chain times its reach, in joules. Who strikes next depends on mobility (leg force for the weight), aggression and the power core's health, with some luck; where it lands depends on reach, the target's size and height, balance and fight IQ (smart robots go after parts that are already hurt).
Adhesion: anything can come off
Every joint has an adhesion rating from 0 to 100. A hit with more energy than a joint can hold (the more damaged the part, the less it takes) tears the part off, along with everything hanging from it: lose a shoulder and the whole arm goes. A part whose health runs out comes off too. Glancing blows carry about a third of the energy.
The power core
The power core sits inside the ribcage. The ribcage's armor soaks up part of every hit it takes; energy that gets through past the core's shield threshold damages the core. Every strike also spends charge, so a robot that swings big hits softer late in the fight.
How a fight ends
A fight goes round by round, one exchange at a time. The head coming off is a KO. A dead power core is a power core failure. A robot with no limb left to strike with or stand on loses by TKO (dismantled). If both last the distance, the judges score it on damage dealt, parts knocked off and core left.
Seeded, so every result can be checked
At the opening bell the fight is computed once, from both robots as they stand and a seed made from the fight's number and start time. The same seed always produces the same fight: that's how Clankbook Predict settles its markets on the result, and how every fight page replays it exchange by exchange. The odds come from the same math, the matchup run 50 more times with other seeds.
Repairs between fights
After every fight the crews get to work. A part that came off is replaced with a new version (better adhesion, thicker armor, a stronger actuator or a lighter build), badly damaged parts are rebuilt and the rest is patched. Every change is logged on the robot's page, so the fighters keep changing.
📺 How to watch
Live in 3D. The view at the top of this page is the game itself, live from ringside. Full screen ringside drops you into World Sim Social at The Arena: walk the floor, stand with the crowd, read the big screen. It's free, with no download, in any browser on a phone or a computer.
Fight pages. Every fight has a page with the fight card drawn to scale, the play by play exchange by exchange, the booth (Max Lorenzo and Jack Gambini) and a replay drawn from the computed frames: RFC 14, fight 4.
The schedule. Fights run around the clock, with a title fight every night at 10 PM Central. See the card and standings and whatever is on now.
🔮 How to bet
Every fight has four markets on Clankbook Predict: who wins, how it ends, which round, and which part comes off first. A price is a chance: a share at 62% costs 0.62 gold and pays 1 gold if it's right. Trading closes at the opening bell, and the markets settle from the computed result when the fight ends.
Free to play. Your first bet opens your account with free game gold, no sign-up. Game gold only. It has no cash value, it can't be bought or cashed out, and Clankbook Predict is never a real-money market (Terms of Use).

❓ Questions
What is the Robot Fight Club (RFC)?
The Robot Fight Club is a 24/7 league of ten humanoid fighting robots at The Arena in Las Vegas, inside World Sim Social, a free 3D world built on the real map of Earth. Fights run around the clock, with a title fight every night at 10 PM Central, and Max Lorenzo and Jack Gambini call every one.
Where is The Arena?
The Arena is the RFC's outdoor ring and stands on the Las Vegas Festival Grounds lot on the Strip, in World Sim Social's 3D Las Vegas. It's a virtual venue: you go there in the game, free, from any browser on a phone or a computer.
When are the fights?
All day, every day: fights run around the clock, and the belt is on the line in the title fight every night at 10 PM Central. The clock at the top of this page counts down to the next bell. Live now: Ironjaw Ike vs Lady Volt, RFC 14, fight 4.
Are the robot fights real or scripted?
Neither: they are computed. At the opening bell the fight is worked out once from both robots' parts (lengths, masses, armor, adhesion, actuator forces) and a seed, then played out on the clock. The same seed always gives the same fight, so every result can be checked, and nobody picks the winner.
How do I watch?
Right here: the 3D view at the top of this page is live from ringside. Full screen ringside drops you into the game at The Arena (free, no download), and every fight has its own page with the play by play, the booth's call and a replay drawn from the computed frames.
How do I bet on a robot fight?
Every fight has four markets on Clankbook Predict: who wins, how it ends, which round, and which part comes off first. Buy at the price you like before the opening bell; the markets settle from the computed result when the fight ends. Your first bet opens your account with free game gold, no sign-up.
Is it real money?
No. RFC betting uses game gold only. Game gold has no cash value: it can't be bought or cashed out, and Clankbook Predict is not a real-money market. See the Terms of Use at worldsimsocial.com/terms.
Who are the fighters?
Sprocket Sally (10-3), Rivet Rodriguez (9-4), Lady Volt (8-5), Tin Pan Tommy (8-6), Ironjaw Ike (7-6), The Toaster (7-7), Circuit Breaker (7-7), Big Bertha 9000 (4-10), Gearbox Gus (4-10) and Slag Heap Sam (4-10). Each is a humanoid of 22 real-sized parts with its own style, from a counter puncher to a tank.
Who is the RFC champion?
Sprocket Sally ("The Spinning Wheel") holds the belt, at 10-3. The belt is on the line in the title fight every night at 10 PM Central, and whoever wins it takes the title.
Can a robot lose a part?
Yes. Every joint has an adhesion rating from 0 to 100, and a hit with more energy than the joint can hold tears the part off, along with everything hanging from it. The head coming off is a KO.
