About Country Calling
Geography quizzes whose every answer comes from one verified dataset - and whose flags are drawn from their published geometry, never fetched from anywhere.
Where the answers come from
Every question on this site is generated from a single dataset of countries, capitals,
continents and US states. That dataset was written twice, independently, and the two copies were
compared row by row before either was trusted: 193 of 197 capitals matched on the first pass, and
the rest were resolved by hand with the reasoning recorded. A quiz that teaches a wrong capital is
worse than no quiz, and this is the guard we chose against it.
Why some countries never appear in certain quizzes
Bolivia has a constitutional capital and a seat of government. South Africa has three
capitals. The Netherlands keeps its parliament in a city that is not its capital. Countries like
these make fine reading and rotten multiple-choice, so they are excluded from simple capital
questions and their situations are explained instead. Disputed capitals are described neutrally
and kept out of scored questions.
The flags are drawn, not photographed
Every flag here is rendered from its published geometry. A flag whose identity depends on a
complex emblem is not simplified into a wrong flag – it simply does not appear as an
identification prompt. Four pairs of flags are nearly identical in real life; they have their own
quiz, where the resemblance is the subject.
