Eurozone quiz

What's on this map

The 21 countries that use the euro as members of the eurozone. Bulgaria is the newest, joining on 1 January 2026, after Croatia in 2023. The euro started in 1999 as an accounting currency, and the notes and coins arrived in 2002.

The quickest way to learn this map is to start from the European Union and take six countries away. Denmark, Sweden, Poland, Czechia, Hungary and Romania are EU members that still use their own currencies, so they stay blank. Everything else in the EU is on the map.

That leaves a solid western block from Portugal and Ireland to Germany and Italy, the Benelux countries, Austria, Finland, and Greece with Cyprus and Malta in the Mediterranean. In the east the euro area is patchier: the three Baltic states, Slovakia, Slovenia, Croatia and now Bulgaria.

A few places outside the EU also use the euro, such as Montenegro, Kosovo and the European microstates, but they are not eurozone members and are not part of this quiz.

The ones people miss

• Bulgaria – the newest member, on the Black Sea. Hook: it joined on 1 January 2026, while neighbouring Romania still uses the leu.
• Croatia – joined in 2023. Hook: the long Adriatic crescent, capital Zagreb.
• Slovakia vs Czechia – once one country, now on different currencies. Hook: Slovakia, the eastern half, uses the euro; Czechia keeps the koruna.
• The Baltics – all three are in. Hook: Estonia 2011, Latvia 2014, Lithuania 2015.
• Denmark and Sweden – rich EU members that people assume are in. Hook: both keep their own krone and krona.

How to learn it

• Learn the six EU blanks first; the rest of the map follows from them.
• Do Find on the map in two sweeps: the western block, then the eastern members.
• Leave Cyprus and Malta for a separate round; they are easy to forget.
• Done is a clean Name them all plus a Sudden death run that gets Bulgaria and Croatia right.
