How it’s scored
From the app's own scoring code, as of September 2026.
Half a shape is drawn beside a fold, and you draw the other half in one stroke. The fold stays where it is: the scorer never moves it to suit your line.
Your stroke is compared with the exact mirror image of the drawn half. Distances are measured as a share of the shape's diagonal, so small and large shapes are graded alike. Your worst stretch counts for more (58%) than your average distance (42%), so one bad section can't hide behind a good one.
| Distance from the mirror (share of the diagonal) | Score |
|---|---|
| 0.6% or less | 100 |
| 1.2% | 96 |
| 2.2% | 92 |
| 3.5% | 86 |
| 5% | 78 |
| 9% | 52 |
| 12% | 38 |
| 24% | 10 |
A clearly wrong stroke is capped. That covers a missing part of the mirror, a stroke drawn in the wrong place, one too short or scribbled far too long, one on the wrong side of the fold, or a different shape entirely.
Questions
- Does the game adjust the fold to my drawing?
- No. The fold is fixed, and your line is measured against it.
- Why did one wobble cost so much?
- Your worst stretch counts for more than your average, so one bad section shows.
- Can you get 100?
- Yes, if your line stays within 0.6% of the shape's diagonal from the true mirror. What a 100 takes
