Scoring
Overview
Each line you draw is scored out of 10 points, split equally across three metrics: length (~3.3 pts), angle (~3.3 pts), and position (~3.3 pts).
Length accuracy
The percentage difference between your line's length and the target's. A perfect match earns ~3.3 points. You lose all length points once the error exceeds 15%.
Angle accuracy
The difference in degrees between your line's direction and the target's. Lines are undirected — drawing in the opposite direction is treated the same. You lose all angle points beyond 18° of error.
Position accuracy
The distance between the midpoint of your line and the midpoint of the target, measured as a percentage of the canvas diagonal. You lose all position points when the midpoint is more than 10% of the diagonal away.
Timeouts
If you don't draw a line before the timer runs out, that line scores 0 / 10.
