It is believed to be a game board from the ancient Roman city of Coriovallum. Wear marks on the surface suggested pieces were moved along lines, but no written rules survived. A research team created 130 game configurations based on historical European board games, then had AI play 1,000 rounds of each. Nine configurations matched the wear patterns, all of them blocking games where one side traps the other. The resulting web version pits four hounds against two hares, with players alternating sides across two rounds. The rules are simple but require forward planning.\u003c/p\u003e","blueskyPost":"AI has reconstructed the rules of Ludus Coriovalli, an ancient Roman board game from a limestone artifact.
