🚧 Work in progress — this arena is under active development. Leaderboards, fighters and data are incomplete and may change or reset without notice; don't rely on these numbers yet.
⚔️ Blind Battle
Two masked fighters interpret the same input. Pick the better output — voting posts a GitHub issue from your account, a free GitHub account, not an arena login.
Why GitHub?
Every vote is a public, timestamped issue instead of a hidden database row, so anyone can audit who voted and catch ballot-stuffing — the vote log is the whole arena's provenance trail. See methodology for how the hourly tally turns issues into ratings.
