Math Rush
LiveQuick sums, four options, one tap each. Right answers keep the clock running, a wrong one costs two seconds, and the questions get harder the further you get.
Solo rush
45 seconds. How many sums can you clear?
Four options, one tap. Right answers keep you moving — a wrong one costs two seconds off the clock and locks that option out. The questions get harder as you go.
No personal best saved yet — this round can set one.
How to play
- 1
45 seconds on the clock
The moment you start, the clock runs. Answer as many sums as you can before it hits zero.
- 2
Pick one of four
Each sum has four possible answers. Tap the right one and the next sum appears instantly — no pause, no confirmation.
- 3
A wrong answer costs two seconds
Guess badly and that option locks out and two seconds come off your clock. The right answer is still there, so look again.
- 4
It gets harder as you go
Your first sums are single digits. Clear ten and the questions move up to two-digit sums, times tables and division.
Tap or click an answer, or press 1, 2, 3 or 4 for the four options. Every sum works with the keyboard alone.
How many sums is good in 45 seconds?
Eighteen to twenty-five is a solid round for most people, which works out at roughly one sum every two seconds. Past thirty you are barely reading the sum before you answer it, and the difficulty tier makes that genuinely hard rather than just fast.
35+ correctFluent
Under 1.3 seconds per sum, right through the hard tier.
26–34Sharp
Fast recall and very few wasted guesses.
18–25Solid
A strong, steady round — most players land near here.
10–17Getting there
Comfortable on the easy tier, slowing on times tables.
Under 10Warming up
Usually the clock rather than the maths is the problem.
What kind of maths turns up?
Everything is mental arithmetic that fits in your head: addition, subtraction, times tables up to 19 × 9 and clean divisions with no remainder. The first four answers are single digits, answers five to ten bring in two-digit sums, and after that the clock is the easy part. Nothing needs a pen and nothing needs a calculator.
Why a time penalty, not a wrong-answer count?
If wrong answers simply did not count, guessing would be free and the score would mean nothing. Charging two seconds makes a wild guess genuinely expensive — a wrong answer has to be paid for with the only currency the game has. It also keeps the round moving: the clock is the scoreboard, and you can always see exactly what a mistake cost.
Play it with a group
In Tournament mode everyone takes one 45-second round and passes the device on. Standings rank correct answers, and a tie goes to whoever made fewer mistakes. Your personal best stays in this browser, and a challenge link lets you send your score to someone else to try.
Tip: answer before you check. If you stop to verify a sum you already know, the clock has moved on — commit and keep the rhythm.
Number keys 1 to 4 pick the four options, which is usually quicker than reaching for the mouse between sums.
