AREA, NOT OUTLINE
How Cutle scoring works
Every valid line produces two filled areas. Cutle compares their shares, doubles the smaller one, and reports the result out of 100.
The formula in one view
| Area split | Score | 48–52% goal |
|---|---|---|
| 50% / 50% | 100.0 / 100 | Yes |
| 48% / 52% | 96.0 / 100 | Yes |
| 40% / 60% | 80.0 / 100 | No |
The 96.0 rounding edge
The goal uses the unrounded area share. The displayed one-decimal score does not move the boundary.
Why a perfect line exists
Move a line of any fixed angle from one side of a filled shape to the other. The area on one side changes continuously from none to all, so it passes through 50% somewhere. Different angles can produce different perfect lines.
Disconnected pieces still belong to one side
All pieces on the same half-plane are summed. Puzzles use one simple closed polygon without holes or crossing outlines.
First, best, and assisted are separate records
Daily attempts remain attached to their published UTC date and this browser. There is no global leaderboard.
Every score has a blade rank
The four beginner bands use fictional trainees. From 85 upward, historical figures appear as themed mentors; their biographies do not determine the game thresholds.

Original fictional training character
80–84.9 points · Practice yard
