HI vs. AI: Let’s Keep Human Intelligence Ahead

The U.S. Mental Math Federation (USMMF) and Orion Abacus Association (OAA) are proud to present the MM Go World Championship, taking place on Saturday, November 1, 2025 (PDT). All qualified finalists will compete remotely from around the world. This is the only international mental math tournament that allows participants to qualify without fees or special permissions, offers cash awards, and is conducted entirely through a mobile app accessible to everyone.

MM Go is an online, real-time multiplayer mental math battler designed to bring fairness and accessibility to global competition. The MM Go World Championship is a “no-excuse,” equal-opportunity contest, created under the principle that anyone with a mobile device deserves the same chance to compete—free from the barriers of time, geography, or bias. The champions who emerge are truly the genuine World Champions of Mental Math.

Objective

Saving HI: The Human Intelligence Mission

"Mental math is the immunity that keeps human intelligence strong in the age of AI." Competitions inspire consistent practice, and practice builds proficiency. By participating in contests, children not only sharpen their skills but also develop greater interest and confidence in learning mental math.

Beyond encouraging active mental engagement, promoting mathematics learning, and fostering friendships among participants worldwide, the championships also aim to make mental math practice more widespread—reaching not only school-age students but adults as well. As more people become involved, greater value will be placed on mental math as a discipline, raising its collective standard and enhancing the overall level of skill across communities.

In addition to the mobile device used for MM Go, each finalist must prepare at least one additional device equipped with a functioning webcam and microphone so that the Tournament Control Center can monitor the finalist throughout the event.

  10. Makeup Tests Policy
    • At the end of the third game (Addition/Subtraction) or during the 12 minutes break between two games, any finalist who experienced interruptions or technical failures in earlier games will be allowed a makeup test.

    • All makeup tests must be fully video recorded.

    • Immediately after completion, finalists must message the following details to the Zoom host:
      • Nickname
      • Which games were affected
      • The scores of the makeup test
    • The Competition Committee will review the submission and determine the validity of the results of the makeup test.
    • If the makeup test also fails, no further makeup attempts will be allowed. Whatever scores have been obtained, even if zero, will be considered final.
  11. Competition results will be announced shortly after the event, but they will not be considered official until confirmed by the Competition Committee, typically within 48 hours. Once confirmed, all results are final.
  12. Winners will be determined based on the total combined scores from all three games. A maximum of USD $4,000 in monetary awards will be distributed in the World Championship. The awards will be granted to the top five winners in each age group, according to the schedule listed below.

    • 1st place (1 person): US $500
    • 2nd place (1 person): US $200
    • 3rd place (3 people): US $100 each
  13. Team Requirement

    Every finalist must belong to a registered team. This ensures that each participant has an additional reliable point of contact and that communication with the Competition Committee can be conducted more efficiently.
    To meet this requirement, each team must have a designated Team Leader who:

    • Holds a valid MM Go account,
    • Is an adult,
    • Legitimately represents the school or organization (if applicable), and
    • Has agreed to represent and manage the team, including serving as the primary liaison between the team and the Competition Committee.

    Finalists who do not specify a team will be assigned by the Committee to one of the official MM Go teams: Infinity X or Beyond X. Although these teams will have a designated team leader, participants assigned to them will be solely responsible for managing all communications with the Competition Committee. The organizers will not be liable for any missed information, updates, or messages once delivered.

  14. Team Recognition

    • Teams with 8 or more finalists in the championship will have their leader recognized as an Elite Team Leader..
    • The team with the highest average rating of its top four players will be honored as the Champion Team of the Year..
    • Player performance will be evaluated using the Chiou Rating System, which measures results consistently across tournaments and over time.


Join the MM Go World Championship—a revolutionary, gaming-style tournament where qualification is earned, not bought.
