G20 countries quiz

What's on this map

The 19 countries in the G20, the group of major economies. The G20 has two more members, the European Union and the African Union, but they are groups of countries rather than countries, so they are not on the map.

The members are spread across every inhabited continent, which makes this a good world quiz in miniature. In the Americas there are five: the United States, Canada, Mexico, Brazil and Argentina. Europe has four of its own: the United Kingdom, France, Germany and Italy, plus Russia stretching into Asia and Turkey on the border between the two.

Asia has the most: China, Japan, South Korea, India, Indonesia and Saudi Arabia. Then there is one each for Africa and Oceania: South Africa and Australia.

Because the countries are large and far apart, Find on the map is quick. The real challenge is remembering which big economies are not members: Spain, the Netherlands, Nigeria, Egypt and Iran are all left blank.

The ones people miss

• South Africa – the only African country in the group. Hook: the southern tip of the continent.
• Saudi Arabia – the only Middle Eastern member apart from Turkey. Hook: the large country covering most of the Arabian Peninsula.
• Indonesia – a long chain of islands people forget to count. Hook: the only Southeast Asian member.
• Argentina – often confused with being left out. Hook: one of two South American members, alongside Brazil.
• Australia – Canberra / Canada – Ottawa / Turkey – Ankara – the capitals people swap for the biggest city. Hook: none of them is Sydney, Toronto or Istanbul.

How to learn it

• Learn it by continent: five in the Americas, four in Western Europe, six in Asia, then Russia, Turkey, South Africa and Australia.
• Run Capitals early; the trap is guessing the largest city instead.
• Population is a good mode here: India and China far ahead, Argentina and Australia near the bottom.
• Done is a perfect score in every mode, which is realistic with only 19 countries.
