How to play Math Duel
Solve the equations faster than everyone else at the table.
Racing against other players to solve the same equation turns simple arithmetic into a tense sprint where a fumbled keystroke costs you the win.
- Type your answer on the on-screen number pad or your physical keyboard
- Press Enter (or the submit button) to lock in your answer
- Use the minus and backspace keys to correct or negate your entry
💡 Double-check your entry before pressing Enter, since submitting a rushed wrong answer often costs more time than typing carefully.
