I used to play The Game of 20 Squares, the oldest board game which has come down to us.
In 1928, Sir Leonard Woolley excavated five playing boards in a royal tomb in the Sumerian city called Ur. They were made between 2,600-2,400 BC (or BCE if you prefer) and were found with playing pieces and 4-sided dice but no rules. Boards were later found in Iran, Syria, Egypt, Lebanon, Sri Lanka, Cyprus, Crete, King Tutankhamen’s tomb, and the palace of Assyrian king Sargon II. It was played by all social classes.
In the 1980s, Dr. Irving Finkel found the game rules on a crumbling clay tablet in the British Museum and translated them.
The tablet was written in 177-176 BC by a scribe named Itti-Marduk-balatu. Itti was an archaeologist who discovered and recorded the rules of this forgotten game, abandoned long ago for its derivative backgammon.
This is Assyriologist Dr. Irving Finkel in his curator's office in the British Museum. He still lives among us, but he dwells in a mental world long before the invention of the safety razor. He lent one of his ancient chess sets for use as a prop in the first Harry Potter movie.

It was a gambling game with beer as the usual wager, but it could also be used in fortune telling and that I think is unique among board games.
