An international team of researchers has successfully used AI to reconstruct the rules of a mysterious Roman-era board game carved into a limestone slab. The artifact, discovered in the ruins of the ancient town of Coriovallum, had puzzled archaeologists for decades due to its unique pattern of intersecting lines that did not match any known historical games. By utilizing high-resolution 3D scans to map microscopic wear patterns, the team identified where players had repeatedly slid game pieces across the stone. These physical fingerprints of play allowed researchers to use the AI-driven system Ludii to simulate over 100 possible rule sets, eventually narrowing down the most likely gameplay to a blocking game where one player attempts to trap the opponent's pieces.
The discovery, recently published in the journal Antiquity, marks a significant breakthrough in both archaeology and digital humanities, as it provides the first evidence that blocking games were played in Europe centuries earlier than previously documented. Dubbed Ludus Coriovalli (the Coriovallum Game), the reconstruction suggests a strategic two-player battle of wits that likely dates back to the late Roman period between AD 250 and 476. Beyond solving a 2,000-year-old mystery, this innovative marriage of AI simulation and use-wear analysis offers a powerful new toolkit for historians to resurrect lost cultural practices from artifacts that lack written records, proving that even the most silent stones still have stories to tell.
