HuntLoop is a trail of clues laid over a real city. Each clue leads to a waypoint, and the next one only unlocks once you are actually standing there - arrival is checked on real GPS, with a guard against mocked locations, so a finish cannot be faked from the sofa. Riddles, codes and questions can wait at each stop.

Anyone can build a hunt: drop waypoints on the map, write a clue for each, and set how close a player has to get. A hunt goes to the public catalogue or stays private behind a shared link, and it can still be edited once it is out.

A downloaded hunt plays fully offline. Clues and puzzles are checked on the device, and progress syncs once the signal comes back, so a dead zone halfway along a trail stops nothing. Every hunt can be reported, and reports of unsafe routes or trespassing are reviewed first.
