How it works
Every card is won by knowing the world
Part quartet card game, part geography quiz. Luck deals you the family; knowledge wins you the rest.
-
Ask
On your turn, ask any player for a country you need for your set: one missing from a family you hold, or one sharing a currency, language or faith already in your hand.
-
Answer in 25
Win the card by answering a question about it. Four options, 25 seconds, no looking it up. Right, and the card is yours and you ask again. Wrong, and they keep it.
-
Collect four
Win with one family quartet (four from one region) and one attribute quartet (four that share a currency, a language or a faith). Every country you win by answering is kept in your atlas for good, until all 194 are yours.
Family quartet
All four countries of one curated family, such as China, Japan, Mongolia and South Korea.
Attribute quartet
Any four countries that share one currency, language or faith, such as four countries that use the euro.
Watch a turn
Ask. Answer. Win the card.

FAQ
Questions, answered
Do I need to download anything?
No. Quartography plays in your phone or computer browser. On a phone you can add it to your home screen, and after the first load it works offline.
Where do I get the iPhone and Android apps?
The apps are in a friends-and-family preview from 12 October 2026. On Android, download the app directly from this page (an APK file; your phone will ask you to allow the install). The iPhone app is in beta testing on TestFlight. App Store and Google Play listings come later. The browser game has the same cards, questions and modes.
How many people can play?
Solo is you against three computer players (Ada, Kofi and Mei). Family is 2 to 6 people sharing one phone; with 2 or 3 people, computer players fill the seats up to four. A family can have up to 12 people and any number of phones.
Is it too hard for children, or too easy for adults?
Each person picks a level from 1 (Explorer) to 5 (Atlas master). At levels 1 and 2 questions are easier and each card's currency, language and faith are shown; from level 3 they are hidden and you need to know them.
What are family stakes?
An optional chore or treat that rides on a Family game. Before the game you choose whether the winner is excluded or last place does it. Only people take on stakes, never computer players, and a parent confirms each chore with a PIN.
Where is my progress saved?
On your device. If you set up your family, each person’s atlas is also kept on the family server and shared between your family phones, so it’s the same on all of them. Streaks, settings and the stakes list stay on each device.
How do I set up my family?
On the home screen tap Your family, then Create a family: give it a name, set a 4-digit parent PIN and add the people who play. On every other family phone tap Your family, then Join with a code, and type the code shown under Add another phone. Everything is managed later in Settings.
A family phone was lost. What do I do?
On any other family phone open Settings, then Phones in the family, and remove it with the parent PIN. It’s signed out of your family the next time it connects.
