Object: The fox is placed in the middle of the board, and 13 geese are placed on one side of the board. The fox and geese can move to any empty space around them (also diagonally). The fox can jump over geese like in checkers, capturing them. Repeated jumps are possible. Unlike in Halatafl (and in checkers), capturing is not mandatory. The geese win if they surround the fox so that it cannot move. The fox wins if it captures enough geese that the remaining geese cannot surround it anymore. Game variants with 15 and 17 geese are also possible.
