Native Americans had dice and games of probability long before other cultures, study finds

The findings push the origins of chance-based games back by more than 6,000 years and identify 565 diagnostic dice items, researchers said.

  • On Thursday, archaeologist Robert Madden published findings in American Antiquity identifying Native American dice dating back 12,000 years from sites across the United States. The discovery pushes back the timeline of gaming artifacts by 6,000 years.
  • Previously, historians believed dice originated in Old World societies roughly 5,500 years ago. Madden's research reveals Late Pleistocene hunter-gatherers were already using these "simple, elegant tools" to generate random outcomes.
  • Madden established criteria for identifying "binary lots" by analyzing 293 historic sets recorded by ethnographer Stewart Culin. He classified 565 items as "diagnostic" dice and 94 as "probable" dice across 58 archaeological sites.
  • Games of chance served as a "social technology of integration," allowing groups to interact and exchange goods, Madden said. Evidence suggests participants were exclusively women in more than 80% of documented historic dice games.
  • Ancient groups were "intentionally creating, observing, and relying on random outcomes" long before formal probability theory emerged, Madden noted. This discovery reframes understanding of early human intellectual accomplishments regarding the nature of chance.
