Do you know your world flags?

Some flags are easily recognizable the world over—here's looking at you, United Kingdom—but others, not so much. Whether it's a tiny nation whose flag you rarely see or a larger country with unusual iconography or a "special administrative region" that dodges categorization, there are plenty of world flags that fly under the radar. And that's not even counting the surprisingly similar flags, like the nearly identical banners of Chad and Romania or Indonesia and Monaco.

How well do you really know your world flags? You might think you can recognize them all—or at least the major world powers, anyway—but this slideshow quiz could prove otherwise. Stacker compiled a list of 50 world flags as the ultimate test for trivia lovers. See if you can guess which flag belongs to which nation before clicking through to the answer slide.
