Cities With "Stan" in Their Name

Guess the world's twenty most-traded currencies, and the countries or special regions that issue them.

20 random countries have been removed from the map of the world! Can you identify them in 3 minutes?

Difficulty level: impossible and mean-spirited. Can you guess these countries based on a partial view of their flag?

Drag the flag onto the correct state. Careful, though! One wrong move and the game ends.
