What Is Maths Warriors?

Maths Warriors is a two-player dice battle game where mental arithmetic wins fights. Each player commands six polyhedral dice — D4, D6, D8, D10, D12, and D20 — and must capture all of the opponent's dice to win.

On each turn, choose a Strength Attack (your die value must be ≥ the target) or a Mind Attack (combine two or more of your dice with +, −, ×, ÷ to exactly equal the target). Mind Attacks reward fast arithmetic and creative thinking under pressure.

Arithmetic That Actually Sticks

Unlike passive drill apps, Maths Warriors puts arithmetic under competitive pressure — players must calculate multi-step expressions against a clock and an opponent, building genuine fluency in addition, subtraction, multiplication, division, and order of operations.

Created in 2004 by Henry Ong, Founder of SIMCC, the game has trained over 100,000 students worldwide and is the official competition format at the Singapore International Math Olympiad Challenge (SIMOC).
