Every border is gone and one country has been wiped off the map. Name it before the clock runs out.
The world behind this screen is live: it is night wherever it is dark, and the lights are real cities.
197 countries: the 193 UN members plus Vatican City, Palestine, Kosovo and Taiwan. The 14 Oceania countries sit out, and 21 countries too small to spot on a region map (Vatican City, Monaco, Bahrain, the smallest Caribbean islands…) are never the missing one. Borders from Natural Earth (world-atlas). Flags from the worldflags package. Populations are 2026 estimates (Worldometer, from UN World Population Prospects). Terrain colouring is illustrative.
