Clearly Impossible Puzzle - 100, 200, 500, 1000 Piece Challenging Jigsaw Puzzles for Adults | Crystal Clear Difficult Puzzle Game | Perfect for Brain Training, Family Game Night & Stress Relief

This was the MOST fun I've ever had putting a puzzle together. I wanted a challenge and something unique, and this puzzle fit the bill. The added layer of difficulty not knowing whether the piece in hand is oriented "up" or "down" was fantastic. The pieces were very well cut - there is some movement even when they are put together due to the material, but this doesn't take from the quality or experience.I'm definitely keeping my fingers crossed for anything to match this challenge! I hope to see a clearly impossible puzzle with even more pieces or a different spin.---Edit: May 2023I recently discovered the release of the 1000 piece clearly impossible puzzle. This was an even more satisfying challenge than the 500 piece. I started the puzzle on April 24th and finished on May 27th.If you know an avid, confident puzzler this is a fantastic gift. If you like to complete puzzles but you don't enjoy sorting pieces this probably isn't the challenge for you. My best advice for completing this puzzle in a timely manner is sort, sort, sort. I first sort out all of the edge pieces like any other puzzle. No worries...the creators have thrown in false edges AND corners. The border of the 1000 piece was the most confusing guessing game I've ever had to play.After your border is together (and hopefully correct), I sorted every piece by shape and orientation. Then it's process of elimination working your way inward. Patience is required. An eye for "funky shapes" is extremely helpful.I will say that I think the 1000 piece had more "it looks like it fits but it doesn't fit" moments than the 500 piece did. I also think the pieces were a little bit of a rough cut. I took to taking nail clippers and snipping off the jagged edges that sometimes prevented pieces from a snug fit. Yes, just like the 500 piece there is still some "wiggle" to the puzzle. This is just the nature of the material. It simply isn't going to hold together like a cardboard puzzle.The scariest moment of the puzzle was realizing I had "lost" a piece. I knew for sure because it was an inner false edge piece and I was down to less than 100 pieces overall. I counted up all of the edge pieces of that shape in my sort tray and on the board...I had 25 but needed 26 with the missing piece. Thankfully I had taken a picture of the initial edge piece sort. Counted in that photo...26 pieces. I was lucky to find the missing piece on the floor. I was even luckier it was the only piece that was misplaced.Overall this was money and time well spent (for me). I await the next jigsaw challenge. 2000 pieces? 5000? A girl can dream.
