1 in 8 Billion: Life Simulator

Out of eight billion people, whose life will you live this time?

1 in 8 Billion is an offline card game that follows a life from birth to its last memories. Small decisions shape your health, happiness, relationships and money—and the story you leave behind.

A beginning you did not choose
Start a new life in one of 217 countries and territories. Meet your family and the people around you, find your way through school and work, and discover the place you call home.

Two choices, many possible lives
Swipe a card to choose your next step. There is room for kindness and ordinary pleasures, but luck, loss and difficult decisions can change your plans. Read what follows and see where your choices take you.

What remains at the end
Look back on the moments that mattered, then answer one last question. Keep a life card in your collection and save it as an image. Export your full record as an illustrated HTML book or a text file. Another life offers another beginning.

At your own pace
Play offline without an account. The app uses the internet to check versions; once an update is confirmed as required, you must install it to keep playing. Your progress and records stay on your device. Settle into the paper-collage illustrations and music, one card at a time.

About the stories
Characters and events are fictional. Real countries, territories and selected statistics provide context, not predictions about anyone's future. Starting locations are weighted by the population of the supported countries and territories; this is not a model of actual birth probabilities.
Stories include illness, accidents, bereavement, crime and fictional lottery play. Nothing is posted online automatically. Export any memories you want to keep before deleting the app or changing devices.
