The puzzle is very difficult, but the whole family (including great and great grand children) really enjoyed it. If you get stuck, there are many solutions posted on the internet.

Somewhat easy
I enjoyed this puzzle, but don't really feel it is a level 4. It took me and my daughter a couple minutes each to figure it out. (We are very good at puzzles.) I do like that it is very solid and a good size. The pieces generally move freely, however the unevenness in the bends do allow it to jam occasionally. The manufacturing/design could be a little better to prevent jamming and/or the tendency to want to force things. All-in-all, I really like it and will try it on my co-workers next.
