Very difficult. Loved the challenge. Mine did not have a cheat aspect. I don't know why it would be needed. Total time for me to finish was approx. 22 hours.

This is the most difficult puzzle I have ever seen. I love the challenge and will complete it. The frame alone took 3 hours. The chart must be used.

It's very hard but that's what I like about it. And I'm not sure if this is considered cheating but I'm having to use the guide, otherwise it would take a lot longer to finish it.

Not too tough if you look at the box. (Otherwise, I'd imagine, nearly impossible.) Overall a very enjoyable and rewarding experience to put together.

I selected it to be difficult, but it is a gift, so I don't know results. You should dig deeper for MORE DIFFICULT puzzles. I've seen and done some that are not in your collection.
5 Stars Wayne Bodie - Calgary, Alberta
Didn't know what I was getting myself into when I started this puzzle. It's a challenge, but one that is well worth it. It's also Ravensburger so the quality is there. The puzzle also comes with a cheat sheet in case you get stuck.

Love the puzzle...can wait to put it together.
5 Stars carrie - Algonquin, IL
This puzzle was so hard to do, but so awesome. I had to use the guide to get the shape of the piece, no two pieces are alike. It was so fun to do because it was so challenging. I disassembled it right away, because I definitely want to do it again.
