South America's 12 capitals split into a few easy-to-remember geographic clusters. The Andean spine carries the highest concentration — five capitals along the mountain range, including the highest national capital in the world and the second-highest. The Southern Cone holds four more, including two coastal capitals facing each other across an estuary. One country has TWO recognised capitals (constitutional + de-facto seat); another has a purpose-built capital in the central plateau that replaced a coastal one in the mid-twentieth century.

The northern coast and the Guianas round out the set: a Spanish-speaking one, an English-speaking one, and a Dutch-speaking one — a microcosm of the colonial history embedded in the continent's modern map.

Pick a mode and start. Type-in is the deep-end recall mode; multiple choice is the warm-up; tile select sorts the continent's capitals from distractor capitals 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.
