About 1 in 8 Billion
1 in 8 Billion is a life simulator that runs in your browser. About four babies are born every second; you become one of them and live that one life to its end. Where you are born, and to whom, is not your choice, just as it wasn't in real life.
Your birth is drawn from real data covering 172 countries and regions, and illness, poverty, work and relationships happen as often as UN, World Bank and WHO statistics say. You can make occasional big decisions, but you cannot steer a life completely. A full life takes about an hour, and you can share it on the public memorial wall when it ends.
The game says it is made by its operator with AI (Claude); a Japanese report said the first version went from prompt to public link in about four hours. It is free to play in 16 languages, and it is made for ages 15 and up because it covers subjects such as death, violence and suicide, always with where to find help. A classroom mode holds back the heavier themes.
Made with AI tools. The developer says they used AI for: code.In their words: “The game says it is made with AI (Claude), and its numbers are public statistics from the UN, the World Bank and others.”
