How to Play
Solve as many arithmetic problems as you can — one at a time, against the clock.
- Answer by typing or tapping the keypad. It auto-submits.
- Timer per problem. Let it run out and the streak breaks.
- Streak bonus: every 5 in a row bumps the level.
- Levels widen the number range and add operations.
- Modes: Basic (+ −), Core (+ − ×), All (+ − × ÷).
- Division problems always have whole-number answers.
- One wrong answer or timeout ends the run.
