This puzzle is shaped like a swirling galaxy. It is not that difficult to solve but one becomes totally mesmerized by the pieces that move freely. It is more difficult to put them back together then to take them apart. The theme is knot and was designed by Bram Cohen from the United States. The difficulty level is 3.
