A math duel is a head-to-head mental-math sprint. You and your opponent get the same problems, the clock runs for one minute, and most correct wins. Play math online against a live opponent, watch their score climb next to yours, and move your Elo.
Free to play. Same seeded problem set for both players, so the faster, sharper solver wins.
No turns, no waiting. The moment you're matched, the timer starts and you're both racing the same set.
This isn't a casual tap-game with a vanity number. Each duel settles on the Elo system used by chess, with a K-factor of 32: beat someone above you and you climb fast; lose to someone below you and it costs you.
Wins and losses both count, so the 1v1 math leaderboard ranks players by results against real opponents, not by hours logged. Climb it by winning math duels, not by grinding.

Most correct answers in 60 seconds wins. You see your opponent's score climb live as you solve, so you always know whether you're ahead or need to push. After the duel your Elo rating updates with a K-factor of 32 — beat a stronger player and you gain more.
Yes. Every duel updates your Elo and your standing on the 1v1 math leaderboard, so the rankings reflect real wins against real opponents rather than time spent grinding.
