Our game
NUMO DUEL combines short arithmetic challenges with colorful, easy-to-read game graphics. Choose solo practice, a computer opponent or a live online duel with another player. Rounds use configurable difficulties and durations so people can find the pace that suits them.
Designed for short sessions
Each match is designed to be quick to understand: read the expression, choose an answer, collect points and watch the clock. Competitive online ranking is kept separate from local practice performance.
Accessible by design
The game is built for responsive screens with keyboard-operable controls and high-contrast options. A lightweight public website provides information without downloading the game's JavaScript or audio engine.
