Why this is the hardest flag quiz
Most flag quizzes give you three obviously wrong answers. This one doesn't. Every flag here has at least one near-twin somewhere in the world, and the wrong answers are picked from those twins. Expect Chad next to Romania, Monaco next to Indonesia, and all five Nordic crosses side by side.
If you're struggling, read the tips below and study our guide to flags that look alike, then come back. Players who learn the small details (a shade of blue, the order of three stripes, the number of points on a zigzag) beat this quiz quickly.
