1 in 8 Billion

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 220 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

Random lives are free to play offline without signing up. Your progress and records stay on your device. The app uses the internet to check versions; once an update is confirmed as required, you must install it to keep playing.

Your own beginning and the shop

Random lives remain free. Spend 10 gems to choose a name, gender, country and four starting stats. Keep your chosen country and use the dice to randomize the rest. If you need gems, you can choose to watch a rewarded ad or buy a gem pack.

Ads and accounts

A full-screen ad may appear between completed lives, and a banner may appear in a separate area at the bottom, away from cards and controls. The optional one-time ad-removal purchase removes full-screen and banner ads; optional rewarded ads remain available. Prices are shown by the store. Accounts, gems, ads, purchases and restoration require internet access. You can buy ad removal and gems without linking a game account, and restore ad removal using the same store account. Linking a game account is optional; link the same game account on another device to access the same gem balance. Game progress and records stay on your device and are not synced to your account.

Optional usage statistics

Sharing usage statistics to improve the app is off by default. You can turn it on or off in Settings. When enabled, usage statistics are sent over the internet. You can play without sharing them.

About the stories

Characters and events are fictional. Real countries, territories and selected statistics provide context, not predictions about anyone's future. Random 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.
