Curiosity is the only prerequisite.
Three little challenges. A whole world to discover.
Fill the Globe
Name every country in your chosen difficulty. Each correct answer turns a piece of the world green. Duplicate and unrecognized answers have no penalty. Casual lets you play without an account or time pressure. For a ranked challenge, choose Marathon and sign in: the timer starts when the server creates your run and keeps running until you finish.
Guess by Flag
Identify the flag by typing a country name or pinning it on the globe. Choose 10, 25, 50, or all flags in your difficulty. Flags never repeat within a run. Casual games have no time pressure and unlimited mistakes. Marathon games give you three hearts. Every incorrect submitted answer costs one heart, including an unrecognized name.
Find the Country
Make a guess and see how far away the secret country is. Darker reds are closer. Land neighbors show “0 km • Adjacent.” Otherwise, distances use great-circle measurements between stable country reference points. Repeating a guess for the current target doesn’t count again. There are no hearts. Fewest guesses wins a Marathon, with time breaking ties.
A clearer view
The progress bar shows your percentage, filled countries, and countries left. Use the fullscreen button for a globe-focused view with the input, progress, and elapsed time. Press Escape or the exit button to return. The elapsed clock in Casual fullscreen is just for you; Casual games are never ranked.
Grey areas are outside your selected country set and cannot be pinned. In Fill, complete every playable country in a continent to color the entire continent, including its excluded areas, with a celebration. Those extra areas do not add to your score.
Three sizes of world
- Standard: 195 countries, including Taiwan and Palestine.
- Medium: 245 countries, observer states, and inhabited territories.
- Hard: 250 supported entities, including all ISO 3166 territories and Kosovo. Tiny entities use markers where needed.

A nudge, not an answer list
Type a substantial, distinctive part of a name and you may see one suggestion. “Uni” and “United” reveal nothing. “United Ar” can suggest United Arab Emirates. Common aliases such as USA, UK, Czech Republic, and Türkiye work directly.
Marathons and fair play
Sign in before starting. Only completed, verified Marathons enter rankings. Categories stay separate by mode, difficulty, method, and run size. Failed, abandoned, expired, and suspicious runs are excluded. The server controls time and scoring. Reloading does not pause time. Runs expire after six hours.
Your passport
Completed Casual games while signed in and verified Marathons award 50 XP plus 10 XP per country in the run. Levels use 1 + floor(√(XP / 100)). Achievement goals are shown on your profile. Progression never changes your ranking or gameplay.
Be a good travel companion
Choose a respectful username. Report inappropriate profiles from their passport page. Moderators can hide profiles and scores, suspend accounts, and inspect suspicious games.
