How to Play
- Pick a level: Easy (adding and taking away up to 20), Medium (sums up to 100 and times tables) or Hard (bigger numbers and division).
- After a quick 3-2-1 countdown, a sum appears with four possible answers underneath.
- Tap the right answer as fast as you can. A correct answer scores a point and brings up the next sum.
- Tap a wrong answer and your buttons freeze for one second, so think before you tap.
- Keep going until the time runs out or someone reaches the target score.
Rules
In the solo sprint you have 60 seconds to get as many right as possible. After a wrong answer you lose one second and a new sum appears, so random guessing never pays. Your total correct is your score.
In a split-screen duel, both players see the same sum at the same moment. Whoever taps the right answer first takes the point and a new sum appears for both. A wrong tap freezes only the player who made it, leaving the question open for the rival. The first player to reach 10 points wins.
In an online race, both players get the very same list of sums but answer at their own pace. The first to 15 correct wins straight away; if nobody gets there in 60 seconds, the player with more correct answers wins.
Tips & Strategy
- Estimate before you calculate. Most wrong options sit close to the real answer, but not all. For 47 + 38, you know it ends in 5 and sits near 85, which often rules out two buttons at once.
- Check the last digit. For adding and times tables the last digit of the answer is quick to work out. 7 × 8 must end in 6, so any option that ends in another digit is out.
- Learn your tricky tables. The 6s, 7s and 8s cause most slow answers. A few minutes of practice on those rows makes the biggest difference to your speed.
- Turn division into multiplication. For 72 ÷ 8, ask yourself “8 times what is 72?” It is usually faster than dividing.
- Stay calm after a freeze. One wrong tap costs a single second, but a rushed second mistake costs another. Take a breath and read the next sum properly.
Game Modes
Solo is a 60-second sprint that is perfect for daily practice; your best score for each level is saved on this device. Play with Friend turns one phone or tablet into a split screen. Lay the device flat between you — the top half is upside down so the player opposite can read it easily. Play Online is a head-to-head race with someone far away.
Play with Friends Online
Choose Play Online and create a room to get a five-letter code and a share link. Send it on WhatsApp or Telegram, copy it or show the QR code. Your friend opens the link in their browser, joins your lobby and waits for you to press Start. Each of you plays on your own screen with the same set of sums, and you can see each other's progress bar moving as you race. There is nothing to install and no account to create.
Quick Math Duel FAQ
Is this game good for school maths practice?
Yes. The Easy level suits younger children learning addition and subtraction, while Medium and Hard build speed with times tables and division. Short daily sprints are a fun way to improve mental maths.
How does the split screen work?
Place the device flat on a table between two players. Each person uses their own half, with its own four buttons, and both can tap at the same time. Players on a computer can use keys 1 to 4 and 7 to 0 instead.
What happens if we both tap at the same moment?
The first correct tap the device registers wins the point. In practice the quicker player almost always gets there first.
Why do my buttons freeze?
A wrong answer locks your buttons for one second. It stops people from tapping every option quickly and keeps the game about real thinking.
Can I play against the computer?
This game is about your own speed, so there is no computer opponent. Play the solo sprint to beat your own best score instead.
