How to play the currency quiz
Each question names a currency, such as the baht, the kwacha or the euro, and shows four countries. Pick the one that uses it by tapping a choice or pressing 1 to 4. After you answer, the quiz shows the full name and three-letter code of the currency, like Thai baht (THB), and lists other countries that use it.

Shared currencies
Many countries share a currency. Twenty-six of the countries in this quiz use the euro, fourteen African countries use the CFA franc, and several small countries use the US or Australian dollar. Many more have their own currency with a shared name: there are dollars in Canada, Jamaica and Singapore, and pesos across Latin America. To keep things fair, the quiz asks about the currency name and makes sure only one of the four choices uses any currency by that name. If the question is about the dollar, the other three choices will not use a dollar of any kind.
Currencies change, too. Bulgaria switched from the lev to the euro in 2026, Zimbabwe introduced the Zimbabwe Gold (ZiG) in 2024, and Sierra Leone issued a new leone in 2022. The quiz uses the current currency.
Questions
Why does the question say dollar instead of Canadian dollar?
The full name usually gives the answer away. Asking about the dollar, peso or franc makes you think about which countries use that kind of currency.
Can two choices both be right?
No. The wrong choices never use a currency with the same name, and the notes after each answer list the other countries that do.
What are the codes like JPY and EUR?
They are ISO 4217 codes, used by banks and money exchanges. The first two letters usually match the country code.
