Pinpoint
A number appears. Tap where it belongs on the line. The closer you land, the more you score.
How to play
Hit Start. Each round shows a number and a line labelled at both ends — 0 and 100 to begin with. Tap the point on the line where you think that number belongs. The tap commits instantly: your marker appears, the true position is revealed next to it, and you score by how close you were. After five rounds the line stretches to 0–1000, where small misses cost more. Your final score is the total across all ten rounds, out of 1000.
What's a good score?
| Score / 1000 | Level | What it means |
|---|---|---|
| Under 550 | Warming up | Getting a feel for the line. |
| 550–699 | Solid | A reliable sense of where numbers sit. |
| 700–819 | Strong | Consistently close, even on the wide line. |
| 820–909 | Excellent | Sharp eyes and steady hands. |
| 910+ | Uncanny | You more or less see the number line in your head. |
Tips to get closer
- Anchor to the middle. Find 50 (or 500) first, then adjust left or right from there.
- Use the quarter marks. The faint ticks sit at a quarter, half and three-quarters — judge against the nearest one.
- Commit. Your first instinct on where a number sits is usually better than a second-guess.
- Respect the wide line. On 0–1000, being "about right" isn't enough — a small gap is a big miss.
Why estimate on a line?
Knowing roughly where a number sits between two others is the foundation of number sense — the same instinct that tells you a bill looks wrong or a statistic can't be right. Placing numbers on a line is one of the cleanest ways to build and test that instinct, and it happens to be oddly satisfying: one decisive tap, and you find out at once how good your feel really is.
Frequently asked questions
Is Pinpoint free?
Yes, completely free with no sign-up. It runs entirely in your browser and your best score is saved on your own device.
How is my score worked out?
Each round is worth up to 100 points, scored by how close your tap is to the true position as a fraction of the line's length. Ten rounds make a total out of 1000.
Can I move my marker after tapping?
No — one tap commits. The decisiveness is part of the game, and it's a fairer test of your instinct.
Does it work on a phone?
Yes. Just tap the line where you think the number goes; it's designed for touch as much as for a mouse.
