In short
One of 8 Billion is a free life simulator online: a life sim you play in your browser. You are born somewhere in the world, picked the way real births are spread across countries. You grow up in a family, make choices about school, work, love, money and health, and watch one whole life unfold, from first birthday to last.
You don't get to pick where you start. The game is about how much of a life comes down to that, and how much your choices can still change.
What is One of 8 Billion?
It is a life simulation game, and its name says the idea: you are 1 of 8 billion people, and it could have been any of them. It is built around one question: what would your life have been if you had been born as someone else?
You don't build a character or choose a starting point. The game gives you a life, drawn from real-world data. You might be born in a rich country with good schools and hospitals, or somewhere with fewer chances and harder odds. Your family, your money and what is open to you follow from the place you are born into.
From there you live it, year by year. Things happen to you, you make decisions, people come and go, and eventually the life ends. What is left is a story made of statistics, choices and luck.
Three lives, drawn just now
Each one was born and lived to the end a moment ago, in your browser, by the same engine you play, with the choices made at random.
How to play the life simulator
Press Be born. A whole life fits into one sitting.
1A random birth
The globe spins; press again and it stops on your country. Countries with more births come up more often, so you are far more likely to be born in India or Nigeria than in Australia. Where you start decides:
- your country, and whether you grow up in a village or a city
- your family and how much money it has
- your health, and how long people there tend to live
- how likely you are to finish school or go to university
2Choices along the way
As you grow up, the game stops at the big moments: stay in school or start working, move to the city, marry, start a business, go abroad for work. Many choices show you the odds before you take them.
Choices move your health, happiness, education and bonds with people. They don't guarantee anything. The game mixes what you do with the odds of where you live, so a good job, a happy family or a long life is never certain.
3Watch it unfold
The years play on their own. Pause when you like, or speed up to 2× or 4×. Your home is a small 3D world that changes with you: who lives with you, what you own, where you are. Turn it and tap things to look closer.
What makes it different
Most life simulation games, and most life games online, are about building your ideal life. This one starts from the part of life nobody chooses.
Real-world statistics
Each country carries its own numbers, from sources like UN population data, the World Bank, UNESCO and the WHO:
- its share of the world's births, and life expectancy by country
- income, and how many people live in cities
- how many finish school and go to university
- child mortality and the common causes of death
- the age people usually marry, and how many children they have
Money you can see
What you own and what you owe are kept apart, in your own country's currency. A loan for a motorbike, a mortgage, savings put by each month: they show up in your balance and in your home.
A family that carries on
Your family tree grows as you live: parents, brothers and sisters, a partner, children, grandchildren. When a life ends, you can carry on as one of your children.
Why people play it
Curiosity about another life
What if you had been born in another country, to a richer or poorer family? The game turns that question into something you can play.
A new look at ordinary things
School, a first job, falling in love, getting old: ordinary moments look different when they happen to someone else, somewhere else, and that changes how you see your own.
A life sim online you can finish in one sitting
A life takes minutes, so this life simulator game is easy to try. Every birth is random, so every life is different.
Is it accurate?
The game uses real statistics to set where you start and how likely things are to happen. But a simulation is not a prediction. The numbers describe whole countries; they can't say what will happen to any one person. Every life you play is fiction, even when the numbers behind it are real.
The figures are rounded, and the world is still being filled in: today you can be born in 27 countries, which between them account for most of the world's births.
Questions
What is 1 of 8 billion?
About 8 billion people are alive today, and “1 of 8 billion” means one person among them. One of 8 Billion is a life simulator built on that idea: it makes you one of them, picking where you are born the way the world does, weighted by each country's real share of births.
Is One of 8 Billion free?
Yes. This life simulator game is free to play online, in your browser, with nothing to download and no account to make.
Is it a real life simulator?
It is as close to real life as we can make it: where you are born, how long people there live, and how likely you are to finish school or find work all come from real statistics. The life itself is fiction.
Can you choose where you are born?
No. Your birthplace is drawn from real birth odds. You only choose what to do with the life you get.
How long does a life take?
About six minutes at normal speed. You can pause, or play at 2× or 4×.
Is it suitable for children?
It deals with real things: illness, poverty, loss and death. We'd suggest playing it alongside younger children.
Is it a prediction of my future?
No. Every life in the game is fiction. The statistics behind it are real, but they describe whole countries, not you.
One of 8 Billion is a way to see how the place you are born, the choices you make and plain luck come together into one human life.
