A free browser-based life simulator where you are born randomly into one of 172 countries with real-world statistics and live through your entire life.
About 1 in 8 Billion
1 in 8 Billion is a free browser-based life simulator that lets you experience a complete life journey. You are born at random as one of the babies being born now, drawing from real statistics of 172 countries, and live that one life from age 0 to its end. The game covers birth location, family circumstances, life events, and mortality based on public data from the UN, World Bank, and WHO.
You make choices throughout your life—decisions about school, work, love, and leaving home—that affect the odds of different outcomes. A full life takes about 25 to 40 minutes to play. The game runs entirely in your browser with no account or download required. It is written for ages 15 and up, as death, illness, inequality and violence appear at real rates.
The independent edition is not affiliated with 1in8b.life, the original 1 in 8 Billion project. The site uses real birth shares, life expectancy and mortality data from UN World Population Prospects 2024 and UN IGME, while income, schooling, urbanisation and health spending come from the World Bank, WHO and UNESCO.
