AI Reconstructs 1,800-Year-Old Roman Board Game Ludus Coriovalli
Ancient Roman Board Game
I explore how researchers used AI to revive Ludus Coriovalli, an ancient Roman game lost for over 1,800 years. By analyzing wear patterns on a limestone board found in Heerlen, the team reconstructed the rules for this asymmetric strategy game where four Hounds block two Hares. This landmark study proves that microscopic analysis and AI simulations can bring forgotten history back to life.
It is not a game that was passed down through centuries of unbroken tradition; rather, it was lost to history for over 1,800 years until artificial intelligence reconstructed its rules from physical traces.

> No written rules for this game survived antiquity. To reconstruct how the game may have been played, researchers turned to the Ludii General Game System — a comprehensive digital platform developed at Maastricht University that can model and simulate thousands of historic board games. The results were published in the journal Antiquity (Volume 100, Issue 409, 2025).
> Using Alpha-Beta search agents — the same class of algorithm that powered early chess computers — the team ran 1,000 simulated rounds for each candidate ruleset, allowing one second of processing time per move. The AI tracked which lines on the board were used most frequently during play, generating detailed edge-usage statistics....
> Nine game configurations matched the wear criteria. All of them were blocking games, and the most frequently matching format was a four-versus-two game in which pieces start on the board. This site faithfully reproduces one of these AI-validated configurations.
I would say this is more "inspired by" Ancient Rome.

This reminds me of bear games: https://en.wikipedia.org/wiki/Bear_games
Here's a tablebase analysis for a simple bear game I constructed a while back: https://emarzion.github.io/coqtbgen/

Reminds me of the mystery of the Roman dodecahedrons - https://en.wikipedia.org/wiki/Roman_dodecahedron
I was thinking of them yesterday because I noticed one for sale in the antiquities shop in Andor, which brought up all sorts of Earth/Rome/Star Wars cannon questions.

I always like to hear about ancient board game reconstructions. Like music and religion, games are something every culture creates. Another recent example is the case of Liubu, a game from ancient China for which the rules were lost. Still, a reconstruction is being attempted by Carnegie Melon:

Too assymetric IMO. I have no problems winning with hounds even on hard, but I have no chance of winning except against easy.
