How scoring works

A right answer is worth 1 point plus up to 0.5 for speed — the more of the 5 seconds you have left, the bigger the bonus. Wrong answers and timeouts score nothing. The total is scaled to 100.

Ten right answers at about 2.5 seconds each lands just above 80 — the top grade. Nine right needs real speed to get there.

“Top %” is an estimate, not a leaderboard. It models players of different skill answering easy, medium and hard questions (about 76%, 54% and 33% right overall) in 1 to 5 seconds, and shows the share who would score at least as high as you. No one's results are stored.
