Backgammon is played by two persons, on a special "board" with thirty "men," fifteen white and fifteen black (or red), similar to those used for the game of Draughts. The board (see Fig. 1) is square, usually of wood, lined with leather, and is divided into two equal compartments, each with a raised wall or border. It is usually made in two portions,
hinged so as to fold together, and bearing on their outward surfaces the necessary squares for draughts or chess, so that the one board may answer both purposes.
The board is so placed in use that the two compartments, known as "tables," shall lie longitudinally between the players. One of these is known as the "outer," the other as the "inner" or "home" table. Which of the two is for the time being the inner and which the outer table is governed by the arrangement of the men at starting. With the men placed as in Fig. 1, the right hand is the inner or home table, and the left hand consequently the outer table. The portions of the two latter nearest to each player are known as his inner and outer tables respectively.
Each table is marked with twelve "points," six at either end. They are alternately of black and white, black and red, or other distinctive colours. The two points in the inner table farthest from the dividing partition or "bar" are known as the "ace" points, and those next in order as the two or "deuce" points, followed in succession by the three or "trois" points, the four or "quatre" points, the five or "cinque" points, and finally the "six"[[65]] points, next the bar. The points in the outer tables are designated in like manner, but starting in this case from the dividing partition. The ace point in the outer table is more commonly known as the "bar" point.
A pair of dice (or sometimes a pair for each player) and a couple of dice-boxes complete the apparatus of the game.
The men are arranged at starting as shown in
Fig. 1—viz., two of White's men are placed on the ace point in Black's inner table, five are placed on the six point in Black's outer table, three on the deuce point in White's outer table, and five on the six point in White's inner table. Black's men are placed in like manner on the points immediately facing these.
Playing.
The game is commenced by each player throwing on the centre of the board a single die, the higher throw of the two giving the right to begin. In the event of a tie, the players throw again. All subsequent throws are with both dice.
The thrower of the higher number may either adopt the points shown by the two dice as his own throw, or throw again. After throwing, he calls the number of the throw, the higher number first, as "six deuce," "cinque trois," "quatre ace," or as the case may be, and then proceeds to make his move in accordance with it. The movement of the men of each player is from the ace point in his opponent's home table towards the like point in his own, though for many purposes it suffices if he can play them into his own table, independently of their reaching any particular point therein, the object of the game being first to get all the player's men into his own inner table, and then to play them out of it again, according to certain rules to be hereafter stated. The number uppermost on each die entitles the player to move one man forward a corresponding number of points. Thus if he threw "six trois," he is entitled to move one man six points onward, and then the same or another man
