AI Judging
Judged by AI.
Decided by skill.
No human bias, no popularity contests. Every submission is scored by an ensemble of AI judges against a rubric both players can see before the first line of code.
Same rubric for both builds
The scoring rubric is locked before the match starts and applied identically to both submissions.
Seven scored categories
AI judges evaluate everything from prompt accuracy to accessibility — not just whether it runs.
Full breakdown, every match
Win or lose, you get the complete scorecard. Know exactly where the match was decided.
