TDC GamesWorld’s Most Difficult Jigsaw Puzzle – Cats – 500 Pieces Double Sided – 15 in

First off, if anyone happens to be missing a dark gray piece for their puzzle, I apologize, I might have gotten your piece! My copy came with an extra piece shown off to the left of the puzzle in the picture. Anyways, I'm someone who does puzzles semi-casually in the sense that I don't try to hurry or speed puzzle them, but I still do them a lot and like to challenge myself and use strategies as if I'm speed puzzling like sorting the pieces or do little challenges like not looking at the box. But I also like puzzles to take a while since puzzles really help me with stress (a reason I like to solve them without looking at the box is it makes the puzzle experience last longer). And this puzzle was a perfect difficulty! I had a lot of fun figuring out a strategy to sort and match up the pieces, which really helped be able to solve it. Even the pieces are all cut to the same general shape too. It took several days of afternoon/evening puzzling to solve, and it was nice to have a puzzle be able to go that long. The only downsides to this puzzle concept is that you would sometimes have to flip whole chunks of puzzle upside down after matching the pieces up, and pieces don't always stay together when flipping chunks, and there were a few times that I accidentally fit the pieces together wrong (the image and the rotated image, the way the pieces are cut, they line up ALMOST with each other but not quite, but it's still close enough that piece fitting mistakes can happen and then you have to take apart part of the puzzle and figure out which pieces were mismatched and should be on the flipped over side. I still had a lot of fun with it though and it was a great challenge.

Definitely challenging. Just disappointed that a piece was missing. An edge piece. :(Contacted the company that makes it to see about a replacement or if they could send me the missing piece. They said they will see what they can do. Haven’t heard anything since.

This puzzle is definitely challenging....but I love me a 2 sided puzzle....I still got a couple pieces that I can't figure out yet but I will ..live this

Got this for my brother & sister in law since they love puzzles. They completed it but there was a piece missing. We think it's funny since we'll try to hide a piece from then anyway and it could have been their cat but also could have just been missing.

A gift for a friend who loves puzzles and finishes them quickly. She loves a challenge and this one delivers. She is having quite the tussle with it and enjoying every minute.

The media could not be loaded. My husband bought me this puzzle for my birthday. I really enjoyed this puzzle! Especially when I realized I had made a mistake but had to figure out where. I love a good challenge. But I did complete it in 3 days, so definitely not the most difficult. And I knew early on it was going to be an unsatisfying ending because one of the corner pieces didn't fit. Really frustrating! Box was also damaged.

I hate this puzzle because it took us soooooo long to finish. Great purchase.

Puzzle was missing 2 pieces. Puzzle was a XMas gift to a friend and it was very embarrassing for them to tell me that the puzzle was incomplete.
