One rating for everything you know. Duel real players and find out where you really rank — against your friends, your country and the world.
From a broad field to something very niche.
Pick History, or the narrow quiz inside it. You compete on that topic’s ranking. Your Elo improves or drops after each answer. Get a hard one right and you climb. Miss an easy one and you fall.
Get your Knowledge Elo score — free →The same set of 6 questions. A real opponent.
Challenge a friend, a colleague, or anyone in the world. You both face those six questions. It is a 1v1 trivia duel, and your rating is on the line.
Challenge someone now — free →Most trivia games hand out points for showing up. Elo.World gives you a rating.
It comes from chess: every question you answer moves your Elo up or down against the players who faced the same question. Beat a hard one and you climb fast. Miss an easy one and you drop.
No lucky streaks. No vanity points. The number tracks what you actually know.
You start at 1,200. Your Elo score unlocks after 20 quizzes, then it keeps moving for as long as you play. An easy quiz that most players ace will barely lift you. A hard one that most players miss will move you a lot. Tiers run from Beginner up through Expert, Master and Legend. Only about 1% of players reach Master.
Six questions, the same set, real stakes. Your rating is on the line.
This is the multiplayer trivia app for people who want a real opponent. Challenge a friend, a colleague or a stranger to a 1v1 trivia duel. It is the fastest way to settle who actually knows more.
Want to play trivia against real people? Every duel on Elo.World is an online trivia duel with a live player, not a bot. Send the challenge, play, then rematch if you disagree with the result. A daily challenge after that runs about three minutes: you against the field, same questions, same scoring.

Four boards at once: friends, colleagues, your country and the world.
Elo.World is a trivia app with rankings that mean something. Your Knowledge Elo score is your rank. It stays until your answers move it, and the same score places you on every board.
Rankings here do not reset. You are not collecting a streak. You are holding a place.
A ranked trivia game should get harder to fake the longer you play.
Points that only rise reward time online. An Elo rating rewards knowing the answer. That is the difference in this competitive trivia app.

Competitive trivia is trivia where your result counts against other players. On Elo.World, every answer changes a Knowledge Elo score, so you are measured against real people, not a points total. You can duel one person, or see where you rank against friends, your country and the world. Rankings do not reset.
The best competitive trivia game gives you a fair, lasting measure of what you know.

Your number goes up and down with real answers, so a lucky streak cannot fake it.
Each question you answer is compared with everyone who faced it. Get a hard question right and your Elo rises a lot. Miss an easy one and it falls. Your Elo unlocks after 20 quizzes. That is the trivia rating system: one chess-style score for what you actually know.
