The idea is old and durable: something is hidden at a real place, and you have to go there. What varies is whether the treasure is a physical object in a box, a digital thing at a coordinate, or simply a place you have not identified yet. They feel quite different to play, and one of them works far better than the others if you live somewhere quiet.
Geocaching is the long-running example: a real container, hidden at published coordinates, with a logbook inside to sign. Munzee and letterboxing are variations on the same physical idea. What it is good at: the moment of finding a real object under a real rock is not replicated by anything digital. Caches have been maintained for decades, and some are genuinely clever pieces of hiding. What to expect: density varies enormously by region, and a cache is only there if its owner still maintains it. Reading recent logs before you set out saves a lot of searching for something that is no longer there. Bring a pen.
Here the treasure exists only in the game: you walk to a spot, and the app confirms you are close enough to claim it. What it is good at: no maintenance, no litter, no missing container. It can also be placed anywhere, including places where a physical box would be a bad idea, and it can be seasonal or one-off without anyone having to go and remove it. What to expect: precision matters. Good implementations use a claim radius wide enough to forgive GPS drift among buildings but tight enough that you really did have to go there. Kartograf's treasures work this way — hidden by players at real locations for someone else to find.
The third kind hides no object at all. It marks a place you have not been and does not tell you what is there. This is the strongest version for exploring where you already live, because the treasure is the place. A marker on an unfamiliar corner of the map is a reason to walk to an unfamiliar corner of the map, and what you find is a real thing that was always there. Kartograf uses this directly: unexplained points appear as mysteries, and resolve when you reach them. It also lets you place a landmark at somewhere worth knowing about, which becomes a find for the next person.
This is the question that decides which game is worth your time. Physical caching thins out with population, though rural caches tend to be older, larger and better hidden than urban ones — fewer, but often better. Anything that depends on other players being nearby right now is a poor bet outside a city. Games that generate content from your own geography do not care where you live. A fog map has exactly as much unexplored ground in a village as in a capital — arguably more, since the interesting edge is closer.
Kartograf runs in a browser: the map starts covered in fog, clears as you walk, and holds treasures hidden by other explorers, landmarks worth visiting, mysteries to identify, and gates into a fantasy overlay of the same streets. The guest map at /try needs no account. A free Pixygon account keeps the ground you have revealed and lets you hide treasures of your own — the part that turns hunting into something you do for other people as well. If you want a physical find first, geocaching is free to start and there is very likely a cache within walking distance of you right now. The two go together well; nothing stops you clearing fog on the way to a cache.

Walk, and it clears where you have been. Kartograf runs in your browser — no download, and the guest map needs no account.
Start huntingIt depends on whether you want a physical object. Geocaching is the established choice for real containers at real coordinates. If you would rather not depend on someone maintaining a box, a digital hunt like Kartograf's hidden treasures works anywhere and cannot go missing.
Yes — Munzee and letterboxing keep the physical-object idea, while location games with player-hidden digital finds cover the same instinct without maintenance. Kartograf combines hidden treasures with a fog map, so the hunt and the exploring are the same activity.
In Kartograf, yes: you place a treasure at a real location and another explorer has to physically go there to find it. Geocaching allows this too, with a physical container and the responsibility of maintaining it.
Physical caches get sparse but are often better when you find them. Games whose content comes from your own geography — fog maps and hidden-place hunts — work identically anywhere, because the unexplored ground is the content.
