The playing pieces are moved according to the roll of dice, and a player wins by removing all of their pieces from the board before their opponent. Backgammon is a member of the tables family, one of the oldest classes of board games in the world. Backgammon involves a combination of strategy and luck (from rolling dice). While the dice may determine the outcome of a single game, over a series of many games, the better player will accumulate the better record. Thus, records of matches between players are good indicators of relative skill. With each roll of the dice, players must choose from numerous options for moving their checkers and anticipate possible counter-moves by the opponent. In variants that originate from early 20th century New York, players may raise the stakes during the game. There is an established repertoire of common tactics and occurrences.
