The chess.com of mental math.
Mathzer turns mental math into a sport: real-time 1v1 duels, an ELO rating system, leagues to climb—and a real method for improvement.
REAL-TIME DUELS
Face off against a player of your level: same questions, shared timer, the fastest and most accurate wins. Immediate rematch if you want the same outcome.
FROM THE MOON LEAGUES TO THE BLACK HOLE
Each victory raises your ELO rating. Go from the Moon to Mars, traverse the solar system, and aim for the Black Hole, reserved for the very best.
REALLY IMPROVE
An ELO rating for each category (mental math, arithmetic, equations, etc.) to pinpoint your strengths and weaknesses. Analyze your games question by question, then practice exactly what cost you the duel.
PRACTICE-BASED LEARNING
No passively watching videos: each technique is learned by doing it, in stages of increasing difficulty, until it becomes automatic.
CHALLENGES AND CLANS
Challenge your friends, join a clan, compare your progress, and play as a team.
