The MM Go World Championship
Competition encourages learning MM Go World Championship 2021

The US Mental Math Federation (USMMF) and Orion Abacus Association (OAA) are proud to host the MM Go WORLD CHAMPIONSHIP on Saturday, October 30, 2021 (PDT). All qualified gamers will compete remotely. This is the only mental math international tournament that requires no fee, nor special permissions, is by qualification only, and is conducted on a mobile app available at everyone's fingertips.

MM Go is an online real-time multiplayer mental math battler. MM Go World Championship is a "no excuse" and “equal-opportunity” mental math contest created under a true state of fairness in which everyone with a mobile device is given the same opportunity, unhampered by barriers of time, space, finance, artificial prejudices or preferences. The final winners are no doubt the genuine World Champions of Mental Math.


Competitions encourage practice. Practice leads to proficiency. Participating in contests can increase the interests and confidence of children in learning mental math.

In addition to encouraging active mental activities, promoting mathematics learning, and creating friendships amongst participants around the world, other purposes of the championship also include generalizing mental math practice to all school-age students and even adults. When more people are involved, more weight will be placed in mental math, and thus the level of the skill will collectively be enhanced.
