Place four red checkers (the geese) on the black squares on one king row and one black checker on any black square in the other king row (see diagram below). Either side may move first. The geese try to surround the fox so that he cannot move. The fox tries to break through the geese and move to the opposite king row. The geese may only move forward but the fox may move forward or backward. Neither the fox, nor the geese may jump. The game ends when either the fox reaches the opposite king row or when the geese corner the fox and he cannot move.
