Impossible Unicorn - Round Unique Jigsaw Puzzle - Color Changing Iridescent Acrylic 180 Pieces Challenge Game for Adults Gift DIY by GEMTURT (100 Pieces)

My father, wise, old, and a master mind needs a real challenge with puzzles. This was super hard for him cause it made his 86 yr old eyes go nuts. But sure worker that brain! I tried it and found the pieces funny shapes and I worked many! Yet....not a true challenge for a Master.

This came packaged safely and as described. My little brother is autistic and loves challenging puzzles of all sorts. Perfect!

This puzzle is challenging and fun! The pieces are a bit loose when you first start putting it together but once you add more pieces, it becomes sturdier. I really liked the unique challenge of having to find piece by piece instead of using a picture guide like most puzzles. The iridescent shine of the puzzle is also very pretty!

The media could not be loaded.  This puzzle was quite the challenge but in the most fun way! If you're looking for a puzzle that will take you a few days of enjoyment, try this one! Pieces are plastic, opaque and well made!

Very nice gift for the puzzler in your life. The pieces are well made and interesting. Gave as a gift to my mom, and she put it together in a night. My only wish is that it was a little larger!

The name is very fitting for this puzzle… It’s a doozie. At first glance all of the pieces look nearly identical. Then you throw on a light sensitive reflective finish and your pieces are constantly changing color. But that’s what makes this puzzle fun. We had it going for (3) days and decided to wait until our puzzle table came and reboot then. The puzzle will take some time to complete.The puzzle comes in a hard plastic box that looks nice. The pieces of made of acrylic and have smooth edges. The puzzle is absolutely beautiful once you get it going. The colors that reflect off it are great.

This puzzle is definitely unlike any puzzle I have done before. Like normal I started with the edges of the puzzle and quickly found that I had to pay special attention to the details. The edges don't link together firmly like most other puzzles so you have to be a bit gentle or the pieces bump around easily.Another thing to note is that there is nothing that shows which side of the piece is supposed to face up or face down. At least that is what I thought at first, if you look at the pieces in the right lighting at the right angle they will look to have either a whiteish tint or a yellow tint. If you face them all the same way then you won't have to worry about swapping them back and forth during the assembly. I am glad I found this out because half of my border was upside down and I am pretty sure this puzzle would have actually been impossible.The pieces are solidly made and fit together very nicely. I do think the puzzle is slightly overpriced but happy with it overall. Still not sure what the use of the pictured "top" is in the picture though. The listing and box say nothing about it.

Enjoyed this puzzle for the unique quality and pieces. We usually do 500–1000-piece puzzles that seem to get put together rather quickly; not so with this one. The challenge with these pieces is to get them all the same side up as they are clear with no picture on them. The pieces are also not shaped and fit together like traditional puzzle pieces, adding to the challenge and fun.Recommended!
