Short answers about how Rubicon works. If yours isn't here, write to us from the contact page.
Yes, Rubicon. There are no options to pick from. You type what you know in your own words, and an AI judge marks what you meant, typos and all. More on trivia you type.
That's fine. If it's clear what you meant, a typo or an answer in another language still gets full marks. A wrong date, number or name is still wrong, though.
Each answer gets a score out of 100. Covering what the question asked gets full marks, extra correct detail earns a bonus, and a half-right answer gets part of the score. Afterwards you see what you got, what you missed and the full solution.
It reads for meaning and only marks what the question asked for. If you think it got yours wrong, you can appeal once per question. A stronger judge reads your answer again, and your score can go up, down or stay where it is.
53 of them. In a room, everyone gets the same question at the same time, each in their own language. You read the others' answers in your language too, and you're scored in the language you wrote in.
The core game is free. That covers the solo campaign, the Daily, joining rooms, and 12 duels plus 3 hosted rooms a day. Citizen costs $6 a month or $48 a year and removes the duel and hosting limits, adds hints and streak freezes, and unlocks three premium characters. Imperator is $15 a month or $120 a year and adds every premium character and the announcer voices. Full pricing.
Yes. Challenge a friend to a one-on-one duel, or host a room where everyone answers the same questions at once. If nobody's around, you can duel an AI.
You play as one of 104 characters from history, like Hypatia, Ada Lovelace or Mansa Musa. Each one is strongest in the subjects they were known for, so your pick changes which questions go your way. See them all.
A bit. GeoGuessr doesn't give you a list of countries, and Rubicon doesn't give you a list of answers. You work it out yourself, only here it's about every subject instead of the map.
You type your answers on both. On Sporcle, an answer counts if it matches one the quiz maker listed. On Rubicon, an AI judge reads what you wrote, so you can answer in a full sentence or in your own language.
Yes. The Daily is a new set of questions every day, the same for everyone, so you can compare scores with friends.
No install. Rubicon runs in the browser at playrubicon.com, on your phone or computer. Accounts are free, and you can play a round before signing up.
