Human Benchmark Leaderboard

How the Leaderboard Works

Every entry comes from a real test session by a signed-in player. When you finish a test while logged in, your result is saved automatically; only your single best score per test is shown, stamped with the month it was set.

Scores are screened against known human performance limits before being ranked. The Reaction Time test uses performance.now() for sub-millisecond precision, and submissions below the ~100ms physiological floor for simple visual reaction are rejected as impossible. Similarly, Typing Speed scores above 300 WPM are not accepted.

Anonymous scores are saved locally in your browser but never appear here. Create a free account for leaderboard attribution, score history, and percentile tracking over time. Learn more about scoring methodology on the Science page.

Reading the Board

Speed tests (Reaction Time, Aim Trainer, Audio RT) rank lower scores first — milliseconds to respond. Capacity tests (Number Memory, Digit Span, Sequence Memory) rank higher scores first — how much you can hold.

Each test's page shows a score guide with typical ranges from published research, so you can see how a record compares to the general population — see for example what counts as a good reaction time or a good typing speed.
