MathsArena is competitive mental math. Think chess, but the moves are addition, subtraction, multiplication, division, percentages, squares, and time arithmetic — solved as fast as you can type. ▸ PLAY ONLINE First to 5 wins. Type the answer to each problem and rack up points before your opponent does. Wrong answers cost you 3 seconds. Matches are 1v1 against players at your skill level, found in under 15 seconds. ▸ EARN AN ELO Five placement matches put you on the global ladder. Win to climb, lose to drop. Watch your rating rise from Bronze through Silver, Gold, Platinum, Diamond, and Grandmaster as your speed and accuracy sharpen. ▸ XP, LEVELS & LEAGUES Every problem you solve earns XP toward a permanent level and tier — a number that only ever goes up. Each week you're placed in a league bracket with players at your pace: climb the divisions from Bronze to Obsidian, get promoted for finishing on top, and start fresh every week. ▸ DAILY STREAKS Solve at least one problem a day to keep your flame alive. Longer streaks multiply the XP you earn — the daily habit that makes it stick. ▸ COINS & STORE Earn coins from daily puzzles, wins, level-ups, and milestones, then spend them on name colors and arena themes to make your profile your own. ▸ DAILY PUZZLES Six variants — mix, percentages, squares, reverse, two-step, and time arithmetic — each with five problems and a global leaderboard. Solve all six on the same day for a Perfect Day. ▸ PRACTICE SPRINT 60, 120, or 300 seconds of pure mental math. Pick your operations and difficulty. Set a personal best, then break it. ▸ CHALLENGE A FRIEND Send a code-based challenge to anyone. Both players join the lobby, the match starts when you're both ready, and the rematch button is right there when the game ends. ▸ ACHIEVEMENTS First Blood. Rising Star. Veteran. Flawless Victory. Speed Demon. Comeback Kid. Giant Killer. Twelve unlocks across four categories chase the moments that make mental math a sport. Designed to be a calm-mind workout, not a slot machine. No ads. No pay-to-win — coins unlock cosmetics, never rank. No tricks. Just the math, the clock, and the rival on the other end. Account required to save progress.
