World Geography · Countries, Capitals & US States
Every continent, every country, every capital — plus all 50 US states. Study the maps, practice names and capitals, and test yourself, with adaptive weighting that focuses you where it counts.
Auto-swap replaces a mastered country with the highest-weight eligible one, shrinking the active set only when none qualify. Auto-retire simply shrinks the active set — mastered countries drop out.
Choose which places are in your practice pool and review your all-time accuracy for each. Changes here shape every Practice round.
The country list always includes Kosovo and Taiwan (states with partial international recognition — neither is a UN member) and the Dutch Caribbean countries Aruba, Curaçao and Sint Maarten (autonomous constituent countries of the Kingdom of the Netherlands rather than independent states).
