A location-based treasure hunt could connect a story to approved places and a sequence of challenges. The route must be designed around actual access, opening times and the intended audience.
Location readings can be inaccurate, so a challenge may need an alternative confirmation method. Organisers need controls for closing stops or changing routes. Private locations should not be added without permission, and users should not be encouraged to interact with a screen while crossing roads or driving.
Prototype a short route and walk it under realistic conditions. Test a closed stop and poor reception. The app can support an engaging activity, while route assessment, permissions and supervision arrangements remain practical responsibilities of the organiser.
