From the publisher:
Like the swirling shape of the galaxy…that is why this puzzle was named 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 than to take them apart. Take a good look at how the pieces move when taking them apart so you can put them back together again. The theme is "knot." Designed by Bram Cohen of the United States.
