Route Finder

Difficulty-graded challenges from any map.

Route Finder generates a sequence of legs across a map, each scored for difficulty. Players race through the set, with overall time and per-leg accuracy contributing to the final score.

Win condition

Draw a continuous freehand path from start to finish that closely matches the optimal route, without crossing impassable terrain.

Scoring formula

Each leg is scored from 0-100 based on the drawn path's proximity to the optimal route. The final score is based on the combined performance.

• Length score: The game is forgiving of minor detours (up to 15% longer than optimal incurs no penalty). Beyond that, a quadratic penalty drops the score to 0 when the route is over 3x the optimal length.
• Endpoint accuracy: Failing to connect the start and finish nodes precisely incurs a small penalty, proportional to the distance missed.
• Terrain penalty: Drawing through impassable terrain (indicated by map features like water or buildings) applies a per-pixel penalty, capped to avoid completely tanking the score from a single slip.
• Cheat check: Impossibly short routes that cut corners significantly below 95% of the optimal length will trigger a strict mathematical penalty.
