As others have mentioned, the puzzle is not easy but NVP is willing to help if you're stuck; you just need to email them for a hint. I haven't tried emailing yet but I'm planning to take my time solving the puzzle :) It's interesting in a way that it forces you to try different ways to get to that 1 final configuration. It'll be a good tool to teach kids & students alike about flexible thinking & patience. Overall, it's a good product.

This is a really great puzzle and VERY challenging. Haven’t solved it yet.

The description didn’t lie when it said it was impossible. I gave it to my boyfriend as a gift, knowing that he loves puzzles. However, he told me a week later that he loves puzzles that he can solve, and no matter how much he tries, this one has been extremely complicated for him (and me). Hopefully we can solve it one day.

We gave this puzzle to our son as a birthday present and he was absolutely delighted with it! It's a level 10 puzzle and it took him 3 hours to find the clue and another 3 hours to solve it. According to the puzzle maker, he is the first person to solve it!

I've been working and playing with 3D puzzles for most of my life and when I came across this thought "how hard could it be? It is only 2D!"I can tell you that this is not an easy thing to solve. I've spent hours on different ideas and attempts without solving it. If you are looking for a puzzle that will actually challenge you then this is it.The packaging is very nice, and the puzzle comes with a handy velvet back for storage. The pieces are sturdy and well cutGood luck!
