The trickiest flags to guess
Some flags look almost identical. Chad vs Romania. Indonesia vs Monaco. Ireland vs Ivory Coast (green/white/orange, just flipped). Luxembourg vs the Netherlands. The Nordic crosses — Norway, Denmark, Iceland, Sweden, Finland — all share a pattern but differ in colour.
The trick is learning them in pairs, not one by one. FlagMaster does this automatically inside the quiz.
