Math Rush: quick sums against the clock
Math Rush is a free mental math game for your browser. A sum appears with four possible answers, and a timer bar drains while you think. Pick the right answer to add time to the bar and score a point. Pick a wrong one and you lose time. The run ends when the bar is empty, and the game keeps your best score.
How to play
- Tap an answer, click it, or press 1 to 4 on a keyboard. Space or Enter starts a run.
- A correct answer adds 2.5 to 3.5 seconds to the bar. Harder questions add more time.
- A wrong answer takes 2 seconds off the bar, resets your streak and shows the correct answer.
- Each correct answer scores 1 point. From the 5th correct answer in a row it scores 2, and from the 10th it scores 3.
- The questions change as your score goes up: small additions and subtractions, then sums up to 20, times tables up to 10, division, two-digit sums, and finally a mix that includes missing numbers like ? + 7 = 15.
- The bar drains a little faster the higher your score, so every run ends eventually.
Tips
- Accuracy pays more than speed. A wrong answer costs time and your multiplier.
- Look at the last digit first. The wrong answers are often only 1, 2 or 10 away from the right one.
- For a times question, the wrong answers are often the next or previous entry in the same table.
- Turn a missing-number question around: ? + 7 = 15 is the same as 15 − 7.
FAQ
Is my best score saved?
Yes, your best score is stored in this browser, so it is still there when you come back.
Are there negative numbers or fractions?
No. Every answer is a whole number of zero or more, and every division comes out exactly.
Does the timer keep running if I switch tabs?
No. The timer pauses while the page is hidden and while a message box is open.
