A man which reaches the far side of the board becomes a king. However, if it reaches the far side by means of a jump, and is able to jump backward away from the far side over another man or king, it must do so, and does not become a king. A man reaching the far side by jumping becomes a king only if its jump, or series of jumps, terminates there. When a man becomes a king the turn to move passes to the other player, who must crown the new king by placing a checker of the same color atop it. A player is not permitted to make his own move until he crowns his opponent's king.
Kings move forward or backward any number of squares on a diagonal line to an unoccupied square.
Kings capture from any distance along a diagonal line by jumping, forward or backward, over an opposing man or king with at least one unoccupied square immediately beyond it. Kings may never jump over checkers of the same color. Whenever a player is able to make a capture he must do so. When there is more than one way to jump, a player must choose a sequence of jumps which results in the capture of the greatest possible number of opposing units, men and kings each counting as one unit. The incorrect move must be retracted, and a correct move must be made.
