SetupBackgammon is a game for two players, played on a board consisting of 24 triangles (points). The triangles alternate in color and are grouped into four quadrants of six triangles each. The quadrants are referred to as a player's home board and outer board, and the opponent's home board and outer board. The initial arrangement of stones is:
ObjectThe object of the backgammon is move all your stones into your own home board and then bear them off. The first player to bear off all of their checkers wins the game.
BeginTo start the game, each player throws a single die. This determines both the player to go first and the numbers to be played. If equal numbers come up, then both players roll again until they roll different numbers. The player throwing the higher number now moves his checkers according to the numbers showing on both dice. After the first roll, the players throw two dice and alternate turns.
DoublingEach game starts at one point. During the game, a player may feel that he or she has a sufficient advantage. In this case he or she can propose doubling the stakes. This can be done this only at the start of his own turn and before rolling the dice. A player who is offered a double may refuse, in which case he concedes the game with one point. play A player who accepts a double becomes the owner of te cube. Redoubles are possible. If a player refuses a redouble, he must pay the number of points that were at stake prior to the redouble.
Automatic doublesThis is a optional rule.
If identical numbers are thrown on the first roll, the stakes are doubled. The doubling cube is turned to 2 and remains in the middle.
End of the gameAt the end of the game, if the losing player has borne off at least one checker, he loses only the value showing on the doubling cube (one point, if there have been no doubles).
However, if the loser has not borne off any of his checkers, he is gammoned and loses twice the value of the doubling cube.
If the loser has not borne off any of his checkers and still has a checker on the bar or in the winner's home board, he is backgammoned and loses three times the value of the doubling cube.
