One roll. One life.

You do not choose the country, the family, or the year. You only decide what to do with the years you get.

Be born anywhere

A country is drawn by its real share of the world's births.

Live your days

A year passes in about a minute. Pause, speed up, or watch.

Make your choices

School, work, love, leaving home. Choices bend the odds.

Meet your ending

Death comes from real life tables, not a script.

Start with a country

Every country has a page with its birth share, life expectancy and the numbers a life is built on.

What does “1 in 8 billion” mean?

The number, the odds, and the misunderstanding.

Odds, in percent

0.0000000125% — and what it actually measures.

Is there an app?

No APK. Play in the browser, add it to your home screen.

The numbers are real.

Every draw, every year and every ending is built on public statistics — not a random number generator with a story attached.

Your life starts somewhere.

You just don't choose where. One roll, one country, one life — from the first day to the last.
