Practise and compete
Short daily practice on the same questions as the TMUA papers, with a race, a rival or a streak to keep you coming back. A little every day adds up.
Compete
Arena
Race a bot to the right answer. Pick an opponent, from a slow warm-up bot to one that answers like an olympian, or set its speed yourself. Best of five, with a rating that moves as you win. There's also a ten-minute ladder that climbs in difficulty until you run out of lives.
Friend duel
Play five questions and send the link. Your friend races your ghost on the same five, and each question goes to the faster correct answer.
Problem of the week
One hard problem, the same for everyone. The discussion of methods unlocks only after you have committed an answer.
Rewards and progress
Every question you solve earns coins, and harder questions earn more. How coins and unlocks work.
Rewards
Level up from Point to Invariant, keep a daily streak alive, take on the daily challenge everyone gets, clear three weekly quests, collect 44 badges across four tiers and unlock themes that re-colour the whole site.
Shop
Spend coins on titles, streak freezes, themes and maths minigames. Every locked TMUA set except J can be unlocked here too (Sets E to I, K and L), and the vault holds a chapter of Beyond the Incenter, then the whole book, for the most dedicated.
Labs
Maths minigames you unlock in the Shop.
