The limestone object, about 21 centimetres wide and shown here with stone counters, caught archaeoludologist Walter Crist’s eye in the Het Romeins Museum in Heerlen. To crack its rules, Crist and his colleagues applied an AI-powered game system that contains the mechanics of thousands of games, past and present, from around the globe. (Het Romeins Museum)
Researchers say they have figured out the rules of an ancient Roman board game. The team simulated thousands of turns based on more than 100 games that could be played on the linked lines inscribed on a stone found in the Roman settlement of Coriovallum, now Heerlen in the Netherlands. One set of rules best matched the wear-and-tear on the stone: a blocking game they’ve nicknamed Ludus Coriovalli (‘the game from Coriovallum’).
