one piece left on the board has lost the game. R.C. Bell's reconstruction (1960–1969) Using an 8×7 (or presumably 8×8) board each player has 17 pieces, one blue, the others either white or black. The white and black pieces are placed two at a time by alternate turns of play anywhere on this board. During this first phase no captures are made. When the 32 pieces are in position each player adds his blue piece, the Dux. The pieces move forwards or backwards or sideways one square at a time. There is no diagonal movement. A piece is captured when the opponent brackets it orthogonally between two of the opponent's pieces, or between an opponent piece and a corner (but not side) square. The Dux is captured like any other piece. A piece that makes a capture gains an immediate second move. The Dux can move like the rest of the pieces, or can jump over an enemy piece that is in an adjacent square. The jumped piece is not captured by the move. Of course, the move can have as consequence the capture of another piece. If a piece is moved voluntarily between two enemy pieces, it is not captured. A player who loses all his pieces loses the game. If no captures are made in thirty moves, the game is ended, and the player with more pieces on the board wins. W. J. Kowalski's reconstruction The board has eight ranks and twelve files. Each player has twelve men and a dux, black on one side and white on the other. In the starting array the men fill the first rank and the dux stands on the second, on the square just to the right of the center line (from each player's point of view). On the board of ten squares by eleven, the dux starts in the center of the back row, flanked by five men on each side. Black moves first. Each piece may move any unobstructed distance along a rank or file (like the rook in chess). A man is captured if the enemy places a piece adjacent to it on each side in an orthogonal line. Multiple men in a line can be captured together (Kowalski later abandoned this feature). If a piece is moved voluntarily between two enemy pieces, it is not captured, but the player so moving should point out the fact, to
