MathsArena
Competitive Mental Math
Free · Designed for iPad. Not verified for macOS.
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. Notification permission is asked once after sign-in and powers challenge invites + daily streak reminders only.
