Country Quartet is a card game about the countries of the world, for Android phones. You play against three computer opponents and ask them for the country cards you need to complete regions of four, such as the Nordic Countries. There are 52 countries in 13 quartets, and every card shows the country's flag, capital, language and currency. The game is free, needs no internet connection, and is designed for ages 7 to 14.

How to play
Each turn you ask one opponent for a country you need. A right guess lets you go again; a wrong one means you draw a card and your turn ends. The steps below follow the game's own How to Play screen.
- 1. You get six cards. Every card is a country. The rest of the deck becomes a draw pile.
- 2. Every country is in a region of four. The game sorts your hand into regions for you, and each region has its own colour.
- 3. Ask another player for a card. Pick a region you have started, choose a country you still need from it, and ask one opponent.
- 4. Right guess? Go again. If they have the card, you take it and keep your turn. If not, you take one card from the deck and play passes on.
- 5. Collect all four to score. A full region is a quartet and scores one point. When all 13 quartets have been collected, the player with the most wins; a tie is a draw.
There is no timer, and after every move the game says what happened, in green when it went your way and red when it did not. A History button lists every move made so far, which is useful for remembering who asked for what.
An example quartet: the Nordic Countries
Sweden, Norway, Denmark and Finland make up the Nordic Countries quartet, the example the game itself uses to explain the rules. Hold any one of them and the card tells you the other three you still need.
| Country | Capital on the card |
|---|---|
| Sweden | Stockholm |
| Norway | Oslo |
| Denmark | Copenhagen |
| Finland | Helsinki |
The other twelve quartets are Southern Europe, Central Europe, Eastern Europe, the Middle East, East Asia, South Asia, Southeast Asia, North Africa, East Africa, North America, South America and Oceania.
The country cards and the Countries browser
Every card shows a country's flag, capital city, official language and currency, plus a short fun fact. Under that is a “Collect all 4” checklist naming the whole quartet, with the current country starred. On the Sweden card, for example, the capital is Stockholm, the language Swedish and the currency the Swedish krona.
The Countries screen, on the main menu, lays out all 13 quartets and 52 countries outside a game. Tap any country to open its card. It works as a small picture atlas: a child can look up a card they were dealt, or browse a region before playing.
Activity: from the cards to a map
This takes about 15 minutes and turns one quartet into a map lesson. You need the game, a pencil, and a political world map or atlas, meaning one that shows the borders between countries.
- 1. Pick a quartet. Start with one the child has just completed in a game, or with the Nordic Countries.
- 2. Read the four cards. Open each country in the Countries browser and say its capital out loud.
- 3. Find them on the map. Shade the four countries in one colour and mark each capital with a dot.
- 4. Talk about the shape of the region. Which of the four share a border? Which lies farthest north? Check the answers in the atlas, not the game.
No political map to print? The world maps in the free geography puzzle pack show coastlines only, with no country borders, so use one alongside an atlas: instead of shading each country, mark a dot roughly where it lies and write its name beside it.
For flags instead of maps, print the flag matching worksheet. Nine of its twelve countries are also cards in Country Quartet: Japan, Sweden, Italy, Ukraine, Switzerland, Germany, Bangladesh, Greece and Finland. After the worksheet, find each one in the Countries browser and name its quartet. The other three, France, Ireland and Nigeria, are not in the game, which makes a good last question: which quartet would you put them in?
