The ultimate knowledge competition
One score for everything you know. Answer questions, climb the rating, and find out where your knowledge really stands — against your friends and against the world.
WHAT IS AN ELO SCORE
Your knowledge, in one number.
Borrowed from chess. Every question you answer moves your rating up or down against the players who faced the same question. No lucky streaks, no vanity points — a single, honest number that tracks what you actually know.
