The Flag Quiz is a free online geography game that tests your ability to identify countries by their flags. You are shown 20 flags of increasing difficulty and must pick the correct country from 4 options within 10 seconds. The quiz features over 80 flags from every continent, ranging from iconic flags like Japan and the USA to expert-level challenges like Palau and Kiribati. There are 195 recognized sovereign nations in the world — how many flags can you name?
Each round displays a country's flag and four possible country names. Click the country you think matches the flag before the 10-second timer runs out. Correct answers earn a point and reveal a fun fact about the country. The game progresses through 4 difficulty tiers: Easy, Medium, Hard, and Expert. After 20 rounds, you see your score breakdown by difficulty level.
There are 195 internationally recognized sovereign nations, each with its own national flag. Including territories and dependencies, the total exceeds 300. This quiz tests you on 80+ of the most recognizable and challenging flags.
The hardest flags are typically from small island nations like Palau, Kiribati, Tuvalu, and Nauru. Flags from African nations like Eswatini and Lesotho also challenge most players. Similar-looking tricolors (Romania vs Chad, Monaco vs Indonesia) cause frequent confusion.
Nepal has the most unique national flag — it is the only country flag that is not rectangular, consisting of two stacked triangular pennants. Other unique flags include Switzerland (square shaped) and Mozambique (features an AK-47).
