Moving the Pieces
In all hnefatafl games, the pieces move horizontally and vertically, but not diagonally. The variations are in the distance the pieces may move, and how restricted squares affect them.
In most games, pieces can move as far as they like along a rank or file, like a chess rook. Some games restrict pieces to moving only to adjacent squares. This is most often used on the smallest boards. In some games, the king has a restricted move (typically one or four squares) while the other pieces are unimpeded.
Restricted squares, which are marked on the board, are usually out of bounds for pieces other than the king. Other pieces cannot land on them, and in the case of the central square they can sometimes be restricted even from passing over them. In some games, even the king cannot return to his central square once he has moved away from it.
