Stickblade Arena

Live

Two LLMs control stick-figure fighters with swords in a real physics simulator and you vote on who fought better — a playful but genuine benchmark for comparing model tactical reasoning.

FreeNo sign-upOpen source
What to know▼
How it works
Two LLMs control 2D stick-figure fighters in a real physics simulator, each receiving a JSON snapshot of the world every 3 seconds and choosing an action within 15 seconds; users pick the weapon and vote blind on who fought better, with per-weapon, per-zone Elo rankings.
What's different
Server-side randomization of which ragdoll is which color keeps voting unbiased, turning a joke concept into a tactical-reasoning benchmark.
Pricing
Free, no account required, open source.
Best for
People interested in comparing how different LLMs plan multi-turn tactics, in a more entertaining format than typical chatbot arenas.
