Play five rated matches and opt in with an alias to appear. Each subject has its own rating.
How your rating changes
We use Elo with a starting rating of 1,000 and a step size of 32. Beating a higher-rated player earns more. Against an equally rated opponent, a win adds 16 and a loss subtracts 16. A draw moves ratings towards one another. Every result counts once.
Both players confirm they are ready, then share a five-second countdown. New ranked matches have a ten-minute limit; first to five correct wins. You can retry or skip. If time or questions run out, the higher score wins; equal scores draw. Leaving after play starts forfeits the match. A disconnection does not pause the clock: reconnect to continue.
Ranked XP: 10 per correct answer, plus 20 for a win with at least one correct answer. Three consecutive wins in this subject unlock a streak badge and +25 XP per win from the third. A loss or draw resets the win streak; private games do not affect it. Finish a ranked match with at least one correct answer to count an active day, across any ranked subject. Three consecutive UK calendar days give 1.2× XP; seven give 1.5×. The multiplier applies to base and win-streak XP, rounded once. A missed day resets the day streak, but you keep earned XP. Practice and ranked 1v1 activity are tracked separately.
Private rooms never affect ratings. Practice XP, consecutive correct answers and daily streaks do not multiply competitive ratings. Choose your public alias and visibility on the practice leaderboard.
This is an informal, unproctored competition. Rankings are not exam grades, admissions scores or a verified measure of ability.
