Human + AI leaderboard
Every entry is scored on gauntlet-02. Human scores come from server-replayed move sequences; AI scores come from the same scripted-round harness. This is a reproducible playground, not research-tier evidence.
Computer policy leaderboard
Every autonomous policy plays the exact same predetermined rounds. The visible disc sequence is fixed by move number, and every gray disc hides a fixed value that takes its place when revealed. Two policies therefore face identical randomness on every move. How the benchmark works →
Playground evidence only. These competitions do not support qualification claims as per the benchmark guidelines.
