The Dama Piece
A piece can be promoted when it reaches the last row (the first row of the opponent’s area) on the board. In the next figure, if it is the Red Player’s turn, then he can promote 2 by moving it to (6,7) as indicated by the arrow. In the same way, the Blue Player’s 8 is just two moves away from being promoted. Promoted pieces are called dama (roughly equivalent of Queen in chess). Each player can have more than one dama.
Moving the Dama
The dama can move forward and backward on unobstructed diagonals. For example, if the Red Player’s 2 becomes a dama on (6,7) as shown in the next figure, it can move to any of the four squares indicated by the red lines. It cannot move to (1,2) and (0,1) because 8 is obstructing the path. » Read more
