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.
Play-by-mail game
Correspondence chess has been played by mail for centuries. The boardgame "Diplomacy" has been played by mail since the 1960s, starting with a printed newsletter (a fanzine) written by John Boardman. More complex games, moderated entirely or partially by computer programs, were pioneered by Rick Loomis of Flying Buffalo in 1970. The first such game offered via major email services was "WebWar II" (based on Starweb and licensed from Flying Buffalo) from Neolithic Enterprises who accepted email turns from all of the major email services including CompuServe in 1983.
