This Puzzle is based on a Celtic interlace knot design. The pieces fit together in only 2 different ways. Quite difficult, yet you can tell which pieces must fit against the edge, so not quite as difficult as it might seem at first. Still– pretty tough! There is some space between the pieces through which you can see the base below.
