Atlas and quiz

Opening World Capitals

195 World entries. 50 states, five territories, and Washington, D.C.

Use Up and Down to choose, then Select.

Arrow keys navigate. Enter selects. Escape goes back; H returns home. You can also tap a screen option above.

Browser demo

Explore real maps, open a place card, or play a five-question round. Browser progress is saved separately from the physical badge.

Controls, coverage and sources

World covers 193 UN members and the two observer states. United States covers all 50 states, five inhabited territories and the federal district. The catalog is dated October 29, 2026. Questions preserve named capital roles and explanatory notes.

Explore starts with a list: Up/Down select and Left/Right change page. Select opens a map, then a detail card. On maps, Up/Down change map page and Left/Right move between places. Back returns to the previous view. Home returns to the badge launcher. The Menu pad remains present; the Capitals app does not assign it an additional action.

Random and Alphabetical orders are saved independently for World and United States. Five-question rounds continue the same pass. Correct answers appear after checking, with missed answers available in the results.

The actual badge model retains its printed appearance and source credits. This browser demo runs the existing badge app in the browser; it does not connect to hardware, use microphone permission, or make AI requests. See the geography sources, map attribution, and runtime notes.
