About this quiz
All 193 member states, filed by the date of admission on the UN's own list. The waves follow history: the founders of 1945, the end of empire in Africa in the 1960s, the small island states of the 1970s and the new states of the early 1990s.
- 42 members were admitted in the 1960s.
- 32 members were admitted in the 1990s.
- The first round of each day is the same for everyone; after that every round is a fresh draw. You can also play the full run.

Note on the data. Admission dates are those on the United Nations list of member states, read on 3 October 2026 and parsed by script. A state that continues an earlier membership keeps the earlier date, as the list has it: the Russian Federation carries 24 October 1945. Vatican City, Palestine, Kosovo and Taiwan are not members and are not asked.
