Backgammon
Backgammon is one of the oldest known board games. Its history can be traced back nearly 5,000 years to archeological discoveries in the Middle East, originally in Iran. It is a two player game where each player has fifteen pieces ("checkers") which move between twenty-four triangles ("points") according to the roll of two dice. The objective of the game is to be first to "bear off", i.e. move all fifteen checkers off the board. Backgammon is a member of the tables family, one of the oldest classes of board games.

...abundant evidence may be marshalled to prove that this is the oldest outdoor game in existence. In the 22nd chapter of Isaiah is found the verse, "He will turn and toss thee like a ball." This allusion, slight as it may be, is sufficient unto the antiquary to indicate that some sort of game with a ball existed as early as 750 years before the Christian era, the epoch customarily assigned to the Book of Isaiah.
