The player whose turn it is to move proceeds by advancing one of his men diagonally forward to an adjacent vacant square. If an opponent's piece occupies one of the adjacent squares, and there is a vacant square immediately behind it, that piece must be capture by jumping over the piece to the vacant square. If there is a choice of captures, the player may choose any of the capture moves; he is not required to play the move which captures the greatest number of pieces. However, once he begins a capturing move he must continue until all the men available on the path chosen have been captured. Uncrowned men may move or capture in a forward direction only. When a piece first reaches any of the squares on the opposite extreme line of the board, it becomes a King. Crowning a piece completes its move, it cannot then capture a piece that is en prise. The King is empowered to move or capture backwards or forwards. The King, like any man, may not refuse to capture when the occasion arises. A draw results when neither of the players can force a win. A game is won when a player captures all his opponent's men or renders them unable to move.
