The world to learn, one game at a time.

Learn

An atlas to explore, not just a quiz

In the atlas, names appear as you zoom in: countries, capitals, cities, rivers, lakes, peaks. Every country has its own card, with its data, its neighbors and a targeted quiz.

• Cards for countries and places
• Offline search on every name
• Countries compared side by side

Paths

Study, practice, pass the test

Lessons by region and by theme — countries on the map, capitals, flags — then review brings back the facts you got wrong until they stick.

Play

A game in a few seconds

Quick Play, Classic, Time Attack, Survival, the Daily Challenge that is the same for everyone each day, and the World Challenge: all 195 countries to find on the map.

• Map, borders and shapes
• Capitals and flags
• Five levels, from Easy to Master

Data

Questions generated from data, never written by hand

195 countries, about 1,000 cities and 1,500 physical features — rivers, lakes, mountains, volcanoes, islands — from open, traceable sources such as Natural Earth, Wikidata, GeoNames, the United Nations and the World Bank. Every piece of data added multiplies the possible questions.

Progress
