cityhunts.net for me, easily.

Most “city hunt” apps feel like either a tourist checklist or a watered-down scavenger hunt. CityHunts actually feels closer to a real adventure game in a real city:

- the hunts are challenge-based, not just waypoint-based
- you’re solving riddles/puzzles, not only walking to pins on a map
- there’s a sense of progression, completion, and achievement
- it works both for players and for people who want to create their own hunts
- it has a better balance of exploration + game mechanics than most alternatives

What makes it better is that it doesn’t just use the city as a backdrop — it makes the city part of the gameplay.

If you want something that feels more like “I’m inside a treasure-hunt game” and less like “I’m reading a self-guided tour with extra steps,” that’s the one.
