European Flags Quiz

The European flags quiz is the hardest flag challenge per square kilometer anywhere on Earth, because Europe invented most of the world's flag patterns and then reused them relentlessly. Forty flags are in play, and the traps come thick: the Netherlands and Luxembourg differ mainly in the shade of blue; Romania and Moldova share a tricolor with only a coat of arms between them; Slovakia, Slovenia, Croatia, and Serbia all riff on the same white-blue-red with different crests; and Monaco-style red-over-white lookalikes lurk in Poland's flipped colors. Meanwhile the Nordic countries fly five variations of the same off-center cross, daring you to remember which cross is Finland's blue and which is Iceland's red-in-white-in-blue. Each round shows one flag and four country names; pick correctly and the country flashes green on the Europe map, anchoring the flag to a real place. Miss, and the right answer is revealed immediately so the pattern sticks. Free, browser-based, reshuffled every round — the fastest way to make Europe's tricolor soup finally make sense.
