Puzzle of my dreams

This puzzle is so freakin cool. It’s funny for me and my Dad because it’s like the meta step of what a puzzle could be. First regular puzzles, then a color spectrum pairing the puzzle down to its basic idea, and then IRIDESCENT COLOR CHANGING making it tricky and forcing us to find new strategies for how to find the pieces that we are looking for. We found two people was awesome, because we could confirm the color matched from more than one angle. Pro tip, lol. Obsessed with this, and I’m not usually even a puzzle person but this was an exceptional Christmas gift. The pieces are thick and high quality. Super fun, very much recommend.

Unique puzzle indeed

Very challenging and beautiful when completed. My only complaint is that a few pieces had delaminated areas, but you can’t see it from a few feet away, so acceptable. Only buy this if you enjoy suffering.

The ultimate puzzle!!!!

This is the most amazing challenge puzzle!! It kept my family enthralled for days till they got it done. It generated so many theories and discussions on how to tackle the constantly changing colour pieces so there was a real sense of achievement when it was completed Exasperating… fascinating…. beautiful…. And great fun!!

It’s more beautiful than I expected

I’ve just received my puzzle, and it’s absolutely beautiful! The iridescent colors of the pieces are not subtle or washed out, it’s really stunning! and it doesn’t seem to be fragile. Of course I don’t think I’m going to solve it any time soon. It looks very hard to solve (which I love) Thank you!
