- Every group is on the board. Click a group (or press its number), then click the bank buttons that belong to it.
- When a group is full the next open one takes over. A wrong pick stays in the bank: it belongs somewhere else.
- Start with the groups you are sure of; what is left helps with the rest.
- Pause whenever you like (Esc). The board hides while the clock is stopped.
Pick the three countries that fit each rule. The groups and the bank appear when you start.
About this quiz
Ribbia counts 197 countries: the 193 members of the United Nations plus Vatican City, Palestine, Kosovo and Taiwan. The rules are computed from Ribbia's shared country list, and each country in the bank fits exactly one of them.
- A rule about letters may fit more places than the three in the bank; the bank never holds a fourth.
- Areas are total surface area for 2023 and populations are United Nations estimates for mid 2025.
- At the end the board shows where every wrong pick really belongs.

Note on the data. Rules are computed from Ribbia's shared country list: surface areas from Table 3 of the United Nations Demographic Yearbook 2023 (Sudan from the World Bank), mid 2025 populations from the United Nations Statistical Yearbook table and capitals from the US Department of State list of independent states, all read on 3 October 2026. Countries with no published figure are not ranked. A test recomputes every rule and checks that each country in the bank fits exactly one.
