Rubicon is trivia you answer in your own words. There are no options to pick from: type what you know, and the game grades the meaning. A typo won't fail you, and adding context raises your score. Every answer comes back with the full solution and the reasoning behind it.
WAYS TO PLAY
• Daily: the same five questions for everyone, about three minutes. Keep your streak and share your result without giving away the questions.
• Campaign: a map of chapters across history, science, art and culture.
• Duel: one on one, and wrong answers cost you health.
• Party: up to eight people at one table, joined by a single link.
• Lyceum: pick a topic and the tutor teaches it before testing you on it.
YOUR CHARACTER
Answer three questions and one of history's great minds, from Hypatia to Tesla, becomes your character. Collect over 100 figures, plus frames and titles, as you play.
MEMBERSHIP
Rubicon is free to play. Two optional memberships:
• Citizen: unlimited duels and party hosting, 10 hints a day, premium characters and voices. Monthly or yearly; the yearly plan starts with a 1-week free trial.
