A world-capitals speed quiz. You’re prompted one country at a time — type its capital and the country fills in with a pin dropped on the real city; hit Reveal if you’re stuck (it won’t count). A spotlight panel zooms to show you where the asked country is while the full map stays put for context. Eight maps (world + every continent), three paces, leaderboards, percentile standings, and a per-answer rarity stat that shows how many other players knew each capital.
