Math Grid
Clear tiles by matching the target sum
Math Grid is a fast, relaxing number puzzle that trains mental arithmetic. A grid of tiles shows digits from 1 to 9, and your task is to clear them by selecting two tiles whose values add up to the target sum shown at the top. Clear the board before the timer runs out to score.
Each round sets a new target number, and any pair that sums to it disappears together. Chaining clears without missing builds a combo multiplier, so smart pairing is rewarded far more than random tapping. Because the target changes, you constantly scan the board for fresh combinations.
The puzzle is generated so that at least one valid pair always exists, which means every board is fair and beatable with focus. Difficulty comes from speed and from the shrinking clock rather than from impossible setups. It is ideal for warming up the brain or filling a two-minute gap.
Play instantly in your browser with no download or login. Math Grid works on desktop and mobile, tracks your best score, and never interrupts you with accounts or tracking. A quiet, satisfying way to keep your arithmetic sharp.
How to play
- Look at the target number at the top of the board.
- Tap two tiles whose digits add up to the target to clear them.
- Clear the whole grid before time runs out; chains build a combo bonus.
Controls
- Click / tap a tile to select it, then tap a second matching tile
- Mouse or touch - no keyboard needed
- N - start a new round
Tips
- Scan for pairs near the target early; small digits pair with large ones.
- Chain clears quickly to grow the combo multiplier for a higher score.
- If no pair is obvious, a new board is one click away - do not stall the timer.
Frequently asked questions
Is every board solvable?
Yes. The generator only ever shows a target that at least one remaining pair can reach, so a solution always exists.
How is scoring calculated?
Each cleared pair scores points, and consecutive clears without a miss raise a combo multiplier for bonus points.
Do I need to install anything?
No. Math Grid runs entirely in your browser and works on both desktop and mobile.
