Backgammon is one of the oldest known board games. Its history can be traced back nearly 5,000 years to archaeological discoveries in Mesopotamia, modern-day Iraq. It is a two-player game where each player has fifteen pieces (checkers or men) that 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 of games, one of the oldest classes of board games.
