The 22 dots in the figure below can be connected by 11 lines, each beginning and ending with a dot (o) and passing through 4 empty cells. Connecting lines may proceed horizontally or vertically, but not diagonally. They may change direction as often as needed, and they should not cross one another.

           |   |   | o | o | o |   |   |   |   |   |
           +---+---+---+---+---+---+---+---+---+---+
