A world atlas.
A badge-sized interface.

Explore

Maps and lists that stay together.

Start with a readable list, open the selected place on a map, then read its detail card. Move between world, continent and regional pages, including locators for small islands and an Antarctica explanation page.

The United States scope includes all 50 states, Alaska and Hawaii map pages, the five inhabited territories and Washington, D.C. Territories and the federal district keep their correct labels.

Quiz

Five questions, then keep going.

Choose Random or Alphabetical order independently for World and United States. Each short round continues the same pass, so the full selected pool is reachable without repeating questions before exhaustion.

Four choices stay readable, answers remain hidden until checking, and feedback explains capital roles where a generic question would be misleading. Results show the score and missed answers. Browser settings and progress are separate from the physical badge.

Data and evidence

A defined catalog, with sources.

The dated World catalog covers 193 UN member states and two observer states. The U.S. pool contains 56 places. Proper names, capital-role questions and source notes come from the existing badge catalog, dated October 29, 2026.

GeoNames data retains its CC BY attribution; map pages are built from Natural Earth public-domain geography. Existing host tests check complete coverage, quiz sequences, persistence migration, map locators and layout. The browser review is separate from physical badge acceptance.
