Math Meteor is a free online mental arithmetic game that runs in the browser with no download and no account. A sum appears at the top of the screen and a handful of meteors fall towards the ground, each carrying a number. Tap the one holding the answer. What makes it a real arithmetic test rather than a shooting game with sums painted on is the wrong answers: they are never random numbers, they are the mistakes people actually make. An off-by-one, a carry dropped, the operands swapped on a subtraction, a factor missed on a times table. That means every meteor on screen is in the right ballpark and you genuinely have to do the sum. Ten levels take you from small additions to mixed four-operation waves of five meteors falling twice as fast. Three lives: a wrong meteor costs one, and so does letting the right one land.
How to play Math Meteor
- The sum is shown in the yellow bar at the top. Every meteor carries a possible answer, and exactly one of them is correct.
- Tap that meteor to shoot it down. A new sum and a new wave arrive immediately.
- A wrong meteor costs one of your three lives, and so does letting the correct one reach the ground.
- A wrong meteor landing costs you nothing — leaving them alone is the right thing to do.
- Meteors fall in separate lanes so they never overlap, and they start at staggered heights rather than as one solid row.
- Levels one to three are addition and subtraction, four is times tables, six brings in division, and seven onwards mixes all four.
- Subtractions never go below zero and divisions always come out exactly — there are no negative answers or remainders anywhere.
- Clear the level target to move on. A level finished with all three lives intact is three stars.
Tips
- Read the sum first, then look at the sky. Scanning the meteors before you know what you are looking for wastes the fall.
- Do not pick by size. The wrong answers are deliberately close to the right one, so "the one that looks about right" is exactly the trap.
- On times tables, check the last digit. Seven eights ends in six, and that alone usually rules out three of the four meteors.
- For subtraction, add upwards instead. Working out what to add to the smaller number to reach the larger is faster and misses fewer carries.
- The high meteors are the safe ones. If two look plausible, shoot the one that is closer to the ground first — you can always come back.
- Take the shot as soon as you are sure. There is no bonus for cutting it fine and a landing costs the same as a wrong answer.
- If a level keeps catching you out, drop back one. The speed steps are small and the arithmetic habit carries straight up.
FAQ
Is Math Meteor free to play?
Yes. It runs in your browser with no download, no sign-up and nothing to buy. All ten levels are included and unlock as you clear them.
Are the wrong answers just random numbers?
No, and this is the thing that makes it a maths game. Each wrong answer is a plausible mistake — an off-by-one, a dropped carry, swapped operands, a missing factor — so every option on screen is in the right ballpark and you cannot get by on eyeballing magnitudes.
What arithmetic does it cover?
Addition and subtraction to start, times tables from level four, division from level six, and all four mixed from level seven. Operands stay within fifteen throughout.
Are there negative answers or remainders?
No. Subtractions are built from their answer upwards so they never go below zero, and divisions are built from their answer too so they always come out exactly.
Do I lose a life if a wrong meteor lands?
No. Only the correct meteor reaching the ground costs you, because ignoring the wrong ones is exactly what you are supposed to do.
Is it suitable for children?
The early levels work well for primary-age practice — small additions, a slow fall and three lives. The later levels are quick enough to be a genuine test for an adult, so there is a comfortable range either way.
How is this different from the other maths games here?
Mental Math Challenge and Multiplication Sprint both ask you to produce an answer. Here the answers are given and the job is recognising the right one under time pressure, which is a different and slightly faster kind of thinking. It is cross-listed under Reaction for that reason.
Does Math Meteor work on a phone?
Yes. The sky is drawn in a taller frame on small screens so you get more warning, and meteors keep to separate lanes so they stay individually tappable.
