Can you name the capitals cities of all 196 countries in the world?

Click on every square of the world map which contains an urban agglomeration with a population of at least 10 million.

On each line, you will see three countries. Guess the one that has the highest population of the three. One wrong guess and it's over.

Drag the pin onto the correct country. Careful, though! Three wrong moves and the game ends.
