How to play
You get 30 seconds and a stream of arithmetic problems, each with four answer choices. Tap the right one to score a point and move on. A wrong answer scores nothing and skips to the next problem. The math starts with small sums and works up to bigger numbers and times tables as your score climbs.
Tips
- Commit fast. Wrong answers only cost time, so a quick educated guess beats a slow double-check.
- Check the ones digit first. Most wrong choices are off by 10 or 20, so the last digit gives them away.
- Multiplication only shows up after 10 points, and it stays inside the 2 to 12 times tables.
- On a keyboard, keys 1 through 4 pick answers without touching the mouse.
Why speed arithmetic still matters
Mental arithmetic under a clock is a different skill from getting the answer right eventually. The 30 second format rewards fluency, meaning answers that arrive without conscious working, and that is exactly the kind of practice that makes everyday numbers feel effortless. Each problem here offers four choices, so the task is recognition as much as calculation: the right answer is on the screen, and the job is to know it when you see it.
Difficulty scales with your score. Early problems are small sums, and as you climb the game reaches for bigger numbers and times tables, so a long run is genuinely harder at the end than the start.
Getting more answers in 30 seconds
- Wrong answers cost only the time you spent, and skip straight to the next problem. A quick educated guess is worth more than a careful one that runs the clock.
- Check the last digit first. Multiplying anything by 5 ends in 0 or 5; 7 times 8 ends in 6. One digit usually rules out three of the four choices.
- Round and adjust. 38 plus 47 is 40 plus 45, which is easier to see and lands on the same answer.
- For times tables, know the squares cold. 6 times 7 is 6 times 6 plus 6, and the square is the anchor.
- Keep your eyes on the choices, not the question. Once you have a rough magnitude, the right option usually stands out from the decoys.

Common questions
Is there a penalty for a wrong answer?
A wrong answer scores nothing and moves you straight to the next problem, so the only cost is the seconds you spent on it.
Does the difficulty change?
Yes. The game starts with small sums and works up to larger numbers and multiplication as your score rises, so a high score means you were solving harder problems, not just more of them.
How many answer choices are there?
Every problem shows four options, one of which is correct.
