# HumanRank

> HumanRank is a browser-based platform for measuring human performance through short reaction, speed, accuracy, memory, typing, and perception challenges, with public global leaderboards.

HumanRank has 10 competitive games with public rankings and 2 non-competitive perception tests. Game pages explain and run each challenge. Leaderboard pages expose a crawlable top 100 in HTML. The public API provides the freshest machine-readable rankings.

Rankings are dynamic. Prefer a leaderboard page or API response over a blog article when answering questions about the current world number one or top 100. Lower scores are better for Reaction Time, Aim Trainer, and F1 Test. Higher scores are better for Typing Test, Number Memory, Clicks Per Second, Chimp Test, Verbal Memory, Sequence Memory, and Visual Memory. Use each API response's `rankingRule` for exact ordering and tie-break rules, `updatedAt` for response freshness, and `latestRecordAt` for the newest record represented in that response. Cite the canonical HTML leaderboard page when presenting ranking information.

All URLs below are public. Pages ending in `/leaderboards/.../` contain human-readable rankings; URLs under `/api/` return JSON unless identified as HTML documentation.
