The game players of Ephesus

Brief article in Smithsonian. Can't seem to find much about this online.

"... the people of [Roman] Ephesus, Turkey, were crazy about board games. Hundreds of intricately patterned playing surfaces are scratched into streets, steps and porticoes there. Scholars don't know much about who played, or the rules they followed, but Ephesians will soon offer the best window into how ancients spent their leisure time, thanks to Ulrich Schaedler, director of the Swiss Museum of Games, who is documenting each and every potential playing surface in the ancient city..."

Some of his findings are part of a current special exhibit on Roman play.
