Archaeologists find 500-year-old board game carved in ruins of Polish castle

Some 500 years ago, construction workers in the midst of building Ćmielów Castle in Poland carved a simple game board into a slab of the sandstone floor as a diversion for their leisure time. At least that's one possible scenario for the existence of a game board recently discovered by archaeologists in the castle ruins; it's also possible the board could have been carved by children or by servants after the castle was completed, or it may have been meant as a symbolic message.

As previously reported, there is archaeological evidence for various kinds of board games from all over the world dating back millennia: Senet and Mehen in ancient Egypt, for example, or a strategy game called ludus latrunculorum ("game of mercenaries") favored by Roman legions. A 4,000-year-old board discovered last year at an archaeological site in Oman's Qumayrah Valley might be a precursor to an ancient Middle Eastern game known as the Royal Game of Ur (or the Game of Twenty Squares), a two-player game that may have been one of the precursors to backgammon (or was simply replaced in popularity by backgammon). Like backgammon, it's essentially a race game in which players compete to see who can move all their pieces along the board before their opponent.
