Problem

Many geolocation games are behind paywalls or have limited free play. I wanted to create a free, unlimited alternative that leverages open-source data for a seamless exploration experience.

Solution highlights

  • Integrated Mapillary API for unlimited, high-quality street view panoramas worldwide.
  • Implemented a smart random location generator that ensures playable locations and avoids dead ends.
  • Built a custom scoring system based on Haversine distance calculation for accurate results.

Impact

Provides a fun, educational, and accessible way for users to explore the world from their browser, with zero cost and unlimited replayability.
