27 seconds, with the game's own fight theme. Every 3D shot is real: five recorded matches, including a machine thrown five metres into the air, built from the same machines the champions page renders.

The whole machine is yours to answer for

Build with real physics

Cores, beams, wheels, spinners, rams, hooks, armor — every part has mass and a weld point. A top-heavy build tips. A nose-heavy ram digs in. The scale never lies.

Program the brain

Wire up sensors — compass trackers, rangefinders, wall sensors — and sequence behaviours on the program canvas. In autonomy fights your code does the driving, not your thumbs.

Fight for rank

Five career leagues, then the online arena: five weight classes, seasonal ratings, and server-refereed ranked matches. Every fight leaves a replay you can study.

Leaderboard

Season 1 is young — most classes are still unclaimed. Every robot below was built and enlisted by a player, and every match behind these ratings was refereed server-side with a replay you can watch.

Fair play, plainly stated

Server-refereed

Ranked fights run on our servers, not your opponent's phone. Same physics for everyone; nobody's device gets to be the judge.
