Field notes
The homepage says birthplace is weighted by annual births across 186 countries, then household circumstances and later events are drawn from country-level statistics. It describes choices about schooling, work, and where to live, with pauses at ages 6, 18, 35, 55, and 72; a group mode lets participants born in the same instant compare lives. The site says play is free, runs in a browser, and stores histories on-device except for online-room play.
