Ludus Coriovalli: using artificial intelligence-driven simulations to identify rules for an ancient board game

The history of games is obscured by our inability to recognise indicators of play in the archaeological record. Lines incised on a piece of rounded limestone found at the Roman site of Coriovallum in Heerlen, The Netherlands, evoke a board game yet do not reflect the grid of any game known today. Here, the results of use-wear analysis are used to inform artificial intelligence-driven simulations based on permutations of rules from historic Northern European games. Disproportionate wear along specific lines favours the rules of blocking games, potentially extending the time depth and regional use of this game type.
