How it’s scored
From the app's own scoring code, as of September 2026.
Only one thing counts: how evenly your cut divides the area. Speed, angle and where you start make no difference.
The scorer takes the difference between the two pieces as a share of the whole. Within about 0.3% scores 100. At 30%, a 65/35 split, the score reaches 0.
Some boards are harder to judge than others, so the tolerance changes with the board:
| Board | Tolerance |
|---|---|
| Pizza | 10% stricter |
| Chocolate bar | Standard |
| Blob | 10% kinder |
| Cake slice | 15% kinder |
| Odd polygon | 25% kinder |
A swipe that stops inside the shape still scores its split, but can't go above 60. Missing the shape scores 0. The result shows how far from 50/50 you landed.
Questions
- Does the shape change the scoring?
- A little. A pizza is judged slightly more strictly, and odd polygons more kindly.
- What if my swipe stops halfway?
- It still scores the split, up to 60.
- Can you get 100?
- Yes, with a cut within about 0.3% of an even split. What a 100 takes

- Yes, on this page, with nothing to install. You get three tries a day here, and the app has no limit.
