KORA is a free online trivia game where two players duel head to head over ten questions, drawn from general knowledge, science, history, sport and entertainment. Each question gives you ten seconds, and a correct answer is worth more the faster it lands — which is what moves your Elo rating. You can play a full quiz duel right now, without creating an account.

How a duel works

Ten questions a duel

Every match is the same length, so winning is never a matter of outlasting anyone — only of knowing more, sooner.

Ten seconds a question

Long enough to think it through, short enough that hesitating hands the point to the other side.

A live Elo rating

Every rated duel moves your score up or down, and the leaderboard that comes out of it is public.

Challenge the people you know

The argument you have been having with the same friend for years has an answer. Send them a duel in that category and let ten questions settle it, on a result that counts like any other.

Watch your rating move

Every rated duel moves your Elo up or down, and your overview keeps the whole curve — wins, losses, the categories you are actually good at, and the ones you keep telling yourself you are.

See where you stand

The rankings are public and you do not need an account to read them. Look at who is at the top before you decide whether you want to be on that list.

Ten seconds, ten questions, one opponent.
