Quickfire
Sharpen your mental arithmetic in a head-to-head tug-of-war. Every quick, correct answer hauls the rope toward you — but the rival adapts to your pace, so you have to keep firing.
How to play
You face a steady stream of arithmetic problems. Each fast, correct answer pulls the rope in your direction; a wrong answer or a slow one lets your adaptive rival pull it back. Drag the rope all the way to your side to win the round.
The rival speeds up or slows down to match you, so the round stays close — your edge comes from accuracy and speed, not luck.
- Answer correctly and quickly to gain ground; hesitate and you lose it.
- Daily mode gives everyone the same seeded set of problems; Practice mode is endless and random.
- Choose Easy, Medium, or Hard to match your level — the problems scale accordingly.
Controls
- Tap the on-screen number pad to enter your answer, then it locks in automatically — fully playable on a phone with no keyboard.
- Use ± to enter a negative and ⌫ to erase a digit.
- On a computer you can also type the digits on your keyboard.
Tips & strategy
- Accuracy beats reckless speed — a wrong answer hands ground straight back to the rival.
- Warm up on Easy to build rhythm, then step up the difficulty once your answers are automatic.
- Practice mode is great for drilling a weak operation (times tables, subtraction) without the pressure of a finite round.
