Ten questions. Fifty-four capitals. One board.

A round is exactly ten questions. Each one names a country and offers four capitals; one is right. The countries are shuffled out of the full bank every time, so no two rounds run in the same order and you can't learn the sequence — only the map.

You answer, you see the verdict immediately, and the correct capital is shown either way. That's the teaching moment: the ones you get wrong are the ones you'll remember next round. There's no timer and no penalty, so a slow, careful round scores the same as a fast one.

At the end you get a score out of ten. Signed in, that score is saved against your account and your best round is what counts — play as often as you like, only the high-water mark stays on the board. Guests can play freely; the score just isn't kept.
