Treasure Hunty in Zagreb

Treasure Hunty Zagreb is a mobile web application for treasure hunting that shows the player GPS location in real time and an interactive map with routes to iconic Zagreb locations. The application was developed exclusively in vanilla JavaScript, HTML and CSS without external development frameworks, and integrates the Google Maps JavaScript API for walking and transit routes and the Web Geolocation API for precise GPS tracking. The game includes gamification elements such as checkpoint quizzes, a scoring system with storage in localStorage and the possibility of installation on a mobile device as a Progressive Web App.
