Welcome! Here's everything you need to know to get started and become a mental math champion.
In 4 steps, you're ready to play your first game.
Launch Mental Math Challenge on your computer, tablet or phone.
Choose your name, grade and avatar. Save your recovery code somewhere safe — it lets you retrieve your progress on another device.
The menu offers several ways to play: Solo, Ascension, Online, Story… Start with Solo.
Pick your level, the operation and the style (20 questions, 3 lives, time attack…) and play!
Play alone at your own pace. Choose level, operation and style. Perfect for practicing or improving on a specific skill.
Start at 1st grade and climb up: 5 correct answers = next level. How many tiers can you chain before time runs out?
Follow the adventure: each chapter introduces new mathematical concepts through a mini-story with challenges.
Face another player in real-time on the same questions. More correct answers + faster = win!
Up to 8 players at once. The lowest scorer of each round is eliminated. Last player standing wins.
Open 24/7 by grade level. A new round starts every 30 seconds: jump in whenever you want.
Two of you fight a math boss together. The tougher the boss, the bigger the reward.
Bronze, Silver, Gold, Diamond… Play each week to climb the ranks and unlock rewards.
The more you play, the more XP (experience points) you earn. XP makes you level up and unlock badges, avatars and backgrounds.
Each correct answer earns XP. Combos (multiple correct answers in a row) earn even more!
Play every day to grow your streak. The more you come back, the bigger the bonuses.
You unlock a badge each time you complete a challenge: 100 questions in a row, first error-free game, full week streak…
At the end of a game, you can win a mystery chest. Three tiers: Bronze, Silver, Gold — based on your performance. They contain collectible cards!
Bronze (always), Silver (≥ 80%, or 3-day streak), Gold (≥ 95% or 7-day streak, or score ≥ 200).
Bronze = 1 card, Silver = 2, Gold = 3. Higher tier = better odds of an epic or legendary card.
220 cards to collect: math wizards, calculation machines, games, constants, shapes, famous quotes, and the great saga of women mathematicians (Hypatia, Ada Lovelace, Emmy Noether, Mirzakhani…). Album complete = you're a true Grand Mathmonster!
Got a duplicate card? Generate a 6 or 7 character code, give it to a friend, they redeem the card. Built-in anti-duplication.
10 minutes daily is better than one hour a week. Your brain remembers better with regular practice.
If an operation gives you trouble (e.g. divisions), pick it specifically in Solo mode and play several rounds.
Multiplication tables are the foundation of mental math. Discover the tables here with tips and methods.
Our tips page covers all the techniques used by mental math champions.
The Coop vs Boss mode or a 1v1 Duel makes math more fun. Motivation comes naturally.
When you unlock a badge or new level, take a minute to congratulate yourself. You earned it!
