More facts: How a duel works
Format: 18 questions: 6 rounds of 3, with 45 seconds per question. One turn is 6 questions, about 3 minutes.
Turns: Turn-based, with 72 hours per turn and 3 turns per player. Players can also play live when both choose to.
Topics: Each round has its own topic, picked from a dealt hand of topics. General knowledge, history, science, nature, geography and hundreds more.
Explanations: Every answered question comes with an explanation from Clash, the app's mascot and tutor. Follow-up questions are limited on the free tier.
Solo: Sessions of 6 questions, including a daily review of questions that are due again.
AI rivals: Six named AI rivals for playing right away, labelled as AI and never rated.

More facts: Learning and rating
Missed questions: Every question a player sees enters a 3-stage review cycle: Learning, Known, Mastered. A missed question becomes due again after 7 days; after a correct answer it waits 90 days. A wrong answer drops one stage, never the whole chain.
Rating: Human duels are rated on an ELO scale. Everyone starts at 1300 (Gold II), and the first 10 or so duels find a player's level. At a settled rating, a duel moves about 8 to 41 points, depending on the final score margin.
Ladder: 8 tiers and 22 ranks, from Iron (100 to 599) to Phoenix (2400 and up).

More facts: Data, with dates
Question catalog: 49,194 live questions across 848 topics (production census, 21 August 2026; deprecated and rejected questions excluded).
