South America's 12 capitals split into a few easy-to-remember clusters. The Andean spine carries five: Bogotá (Colombia, ~2,640 m), Quito (Ecuador, ~2,850 m — the second-highest national capital), Lima (Peru, sea-level on the coast despite Peru being mountainous), La Paz (Bolivia's de-facto seat at ~3,640 m, the highest national capital in the world), and Sucre (Bolivia's constitutional capital and the only South American country with two recognised capitals). The Southern Cone holds Santiago (Chile), Buenos Aires (Argentina, on the Río de la Plata estuary), Montevideo (Uruguay, on the opposite bank), and Asunción (Paraguay, inland on the Paraguay River). Brazil's capital Brasília was purpose-built in the central plateau in 1960 to pull the country away from coastal Rio de Janeiro.

The northern coast and Guianas round it out: Caracas (Venezuela), Georgetown (Guyana, English-speaking), and Paramaribo (Suriname, Dutch-speaking). Bolivia's dual capital surprises people — La Paz is the seat of government, but Sucre is the constitutional capital. Both are accepted as answers here.

Pick a mode and start. Type-in is the deep-end recall mode; multiple choice is the warm-up; tile select sorts South American capitals from European/African/Asian/North American distractors under the clock; match pairs each capital to its country across regional rounds; click-the-map asks you to click the country whose capital is shown. Every mode counts toward your topic mastery.
