How a duel works
- 01
Matched to your level
MathRise pairs you with a real player near your rating. No lobby, no waiting: you race their recorded run, live against yours.
- 02
Same 10 problems, same clock
Additions, subtractions, products, divisions — identical for both of you. Every second counts, and every mistake costs.
- 03
Your Elo moves
Win and you climb, lose and you drop — and beating a stronger rival is worth more. Just like chess.
One app, five ways to train
Every mode wears its own color in the app, and they all serve the same goal: making you faster.
Ranked duel
The heart of MathRise: 10 problems against a rival of your level, with your Elo on the line.
Warm-up
Short bursts to wake up your brain before a duel — with a personal record to beat.
Practice
One skill at a time: addition, subtraction, multiplication, division, times tables, squares, percentages, fractions. It adapts as you go.
Daily Challenge
One try a day, the same 10 problems for the whole planet. Keep your streak and see where you land on today's board.
Group session
Open a room, share the code, and up to 100 players race the same problems live. Made for a class or a group of friends.
Friends & challenges
Add friends by username, challenge them in one tap or with a link, and settle it with a rematch.
Climb from Rookie to Grandmaster
Seven tiers, one rating. Your Elo is a number with a direction — and the leaderboards show where it puts you, worldwide and in your country.

Your first ranked duels are placement duels: they find your level fast, then reveal your starting Elo.
Track your progress
See yourself getting faster
Every ranked duel gets a performance score: your speed against the difficulty of the problems, on the Elo scale. Win or lose, you know whether you played well.
- Your average and your record, called out the moment you beat them.
- “My progress” draws your curve, duel after duel.
- Practice eases off after two misses, climbs back when you're on a roll, and ends with a list of what to review.

Who is MathRise for?
Teens and adults who want to get genuinely faster at mental arithmetic — for school, for exams, or to keep a sharp mind. The design is clean and competitive, not childish. Teachers also run it as a live class game.
How does the ranking work?
MathRise uses an Elo rating, like chess. Every ranked duel moves it: beating a stronger player earns more, losing to a weaker one costs more. Your first duels are placement duels, then you climb seven tiers, from Rookie to Grandmaster.
Do I have to wait for an opponent?
No. You race the recorded run of a real player near your level, on the same 10 problems and the same clock — so a duel starts in seconds, at any hour, in any time zone.
What kind of math is in MathRise?
Mental arithmetic: addition, subtraction, multiplication, division, times tables, squares, percentages and fractions. Difficulty follows your level, from quick sums to two-digit multiplication.
Do I need an account?
No, you can play right away. Pick a username and a country to appear on the leaderboards, and sign in with Apple, Google or email to keep your progress across devices.
Can I use MathRise in class?
Yes. Create a group session, write the code on the board, and up to 100 students race the same problems live — no student accounts needed. The teacher's guide is at mathrise.io/classroom.
