Men may never jump over checkers of the same color. A man which reaches the far side of the board becomes a king. If it reaches the far side by means of a jump, it continues jumping as a king on the same move, if possible, and remains a king at the end of the jumping sequence. 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 may choose any way he wishes, not necessarily the one which results in the capture of the greatest number of opposing units. When a king jumps over an opposing man or king with more than one unoccupied square immediately beyond it, it must land on a square from which it is possible to continue jumping, if there is such a square.
