Guess the Country by Terrain drops you somewhere on Earth with nothing but the lay of the land: no labels, no borders, no markers, just mountains, valleys, rivers and coastlines rendered as a physical relief map. Your job is to name the country you are looking at.

You get six guesses. Every miss helps you twice: the view zooms out one step, revealing more geographic context, and your guess earns a hint row showing the distance, the compass direction and a proximity score from your guess to the mystery spot. Study the dunes, fjords and river deltas like a detective, then close in.

Every player in the world gets the same terrain each day, so scores are comparable and shareable, spoiler-free. Solve the daily, keep your streak alive, then switch to endless mode and explore as many mystery landscapes as you like. After the round ends, the map unlocks so you can pan and zoom freely around the answer.

Guess the Country by Terrain

How to play

Study the terrain view: relief, coastlines, islands, river systems and how rugged or flat the land is.
Type a country name and pick it from the suggestions. You have six guesses.
After a miss, read your hints: the distance and arrow point from your guess toward the mystery spot, and the percentage tells you how warm you are.
Watch the view zoom out with every miss: each step reveals more context, from a local valley to a whole continent.
Name the country to win, then hit “Share result” to copy a spoiler-free score card and challenge your friends.

Game modes

Daily challenge. One mystery terrain per day, identical for every player worldwide, refreshing at 00:00 UTC. Solve it in as few guesses as you can, keep your streak going and compare score cards with friends.

Endless mode. Unlimited random landscapes with the same rules, perfect for practice. Endless rounds never touch your daily streak or stats.

Reading terrain like a pro

Every landscape leaks clues. Long parallel mountain chains suggest the Andes or the Zagros; a dense web of braided rivers points to a great floodplain like the Ganges or the Amazon basin; deep fingered inlets mean fjord country such as Norway, Chile or New Zealand; vast featureless tan expanses whisper Sahara, Gobi or Outback. Even the ocean floor helps: shelf edges, trenches and island chains frame a coastline as distinctively as the land itself.

The zoom-out ladder changes what kind of thinking wins. Up close you are reading geology; by the third or fourth guess you are reading coastline shapes; by the last guess you are reading continents. The best players combine both: use the early view to shortlist a region, then let the distance arrows steer the final pick.

The data behind the map

The relief you see is real elevation data: the game renders hillshading live from the open Mapzen terrain tiles hosted by the AWS Open Data program, which blend sources like NASA SRTM radar topography and global bathymetry. Land and coastlines come from Natural Earth, and the country facts powering the hints come from Mappr’s own open country dataset. There are no API keys, no accounts and no tracking: the game runs entirely in your browser.

Frequently asked questions

Is it the same terrain for everyone today?

Yes. The daily answer is seeded from the UTC date, so every player worldwide sees the same landscape on the same day, and a new one appears at 00:00 UTC. That is what makes shared score cards comparable.

Why are there no labels or borders on the map?

That is the game. Place names or boundary lines would give the answer away instantly, so the view shows pure physical geography: relief, rivers, lakes, coastlines and ocean depth. Reading those is the skill the game trains.

Is this like GeoGuessr?

It scratches the same itch, with two twists: it is completely free with no account, and instead of dropping a pin you play a Wordle-style deduction round with six guesses, distance hints and a shareable score. There is no street imagery, only terrain.

Which countries can appear?

The daily answer is drawn from 164 countries larger than about 5,000 square kilometres, so a zoomed-in view always shows a meaningful piece of land. All 191 countries in the game remain valid guesses.

Where does the map data come from?

Elevation from the Mapzen terrain tiles on AWS Open Data (NASA SRTM and other open sources), coastlines from Natural Earth via the world-atlas project, ISO country codes from Wikidata, and country facts from Mappr’s open dataset. All free, open data with visible attribution in the game.

What happens if I run out of guesses?

The game reveals the answer honestly: the country is highlighted on a world map with its flag and capital, and the terrain view unlocks so you can explore where you were. In daily mode a new terrain arrives tomorrow; in endless mode you can start a new round immediately.
