GoKawiilBorderline game data reveals 37,500 hand-drawn national border maps
An online geography game called Borderline has compiled roughly 37,500 crowd-sourced drawings of country borders and coastlines, aggregating them into a visual map that overlays every submitted outline against the real one. The project breaks results down by country, drawing type (land border, coastline, or daily challenge round), and includes median accuracy scores and error rates for each nation.
GoKawiil's interpretation of the reporting above, not reported fact.
The dataset offers a rare, large-scale look at how accurately ordinary people perceive national boundaries, which could highlight geographic literacy gaps or biases toward more familiar countries. Because contributions come from self-selected players rather than a controlled sample, the results likely skew toward regions the gaming audience knows best, making the findings suggestive rather than statistically representative.
- About 37,500 border and coastline drawings have been collected through the Borderline game
- Data is broken down by country, drawing type, median score, and median error
- The visualization overlays all submitted outlines against the actual national borders
