Start the quiz: FlagsHow to learn them
- Start with families. Tricolors (France, Italy, Ireland, Germany, the Netherlands), Nordic crosses (Denmark, Sweden, Norway, Finland, Iceland) and the Pan-Arab colors give you dozens of flags at once.
- Learn the look-alikes together. Chad and Romania are almost identical, as are Indonesia and Monaco, and Ireland and Côte d'Ivoire have the same stripes in reverse order.
- Pay attention to the details. A coat of arms, a star or the proportion of the stripes is often the only thing that separates two flags.
