Spanish draughts

• 8×8 board, each player has 12 men on the dark squares of the three nearest rows. White moves first.

• The board is mirrored: the long diagonal runs to the player's right.

• A man moves one square diagonally forward and captures forward only.

• A man reaching the last row becomes a king and the move ends. A king moves and captures diagonally any distance, forwards and backwards.

• Capturing is mandatory and a capture must be carried through to the end. Captured pieces are removed after the whole move; a piece cannot be jumped twice. If the capture can continue from at least one square behind the captured piece, the king must land on such a square.

• With several captures available you must take the most pieces, and on a tie the most kings.

• A missed capture does not cost a piece: the server simply will not accept such a move.

• Draw: threefold repetition; 20 moves each with kings only, without a man move or capture; three kings, at least one on the long diagonal, against one king — 13 moves each.

Sources: rules of the Portuguese Draughts Federation (2026) and the Ludoteka description. Our draws follow Ludoteka: 20 moves with kings only, whatever the number of pieces, and 13 moves for “three kings against one”; under the federation's code the 20-move rule applies when each side has at most 4 pieces including a king, and “three against one” gives 12 moves.
