All Flags of the World Quiz

This is the long version of the flags of the world quiz — 180 country flags, not just the famous fifty. It starts where the short quiz stops: once the Stars and Stripes, the Union Jack and the maple leaf are out of the way, you are left with the flags that decide real competitions. The Gulf states that differ only in the width of a red band. The pan-African green-yellow-red family, where Guinea and Mali are mirror images of each other. The Caribbean flags most people have genuinely never seen. The three Central American tricolors that share a blue-white-blue scheme and are told apart only by the crest in the middle. Each round shows one flag and four countries, and every answer lights the correct country up on the world map, so you learn the flag and the place together. Wrong picks reveal the answer straight away, the deck reshuffles every time, and there is no signup or timer — work through it at whatever pace the hard ones demand.
