Ravensburger Krypt Black Puzzle - Unique 736-Piece Challenge for Adults | Softclick Technology Engaging Spiral Cut Design | Quality Craftsmanship | Ideal for Relaxation or Gifting

All one color, so solving the puzzle is based on shapes. Definitely more challenging than standard puzzles, but that makes the solving all the more rewarding.

I absolutely loved this puzzle and I think I will buy the other versions as well. The quality is great (typical of this specific brand) the pieces are thick and stay together without any issues. I didn't want to look at the solutions paper that comes with, so at the beginning it was a bit of a struggle because everything looked identical. After understanding how the puzzle approximately looked like it got so much easier and fun. It is a great gift idea for all puzzle lovers and also for those who love a little challenge. I would repurchase it 100 more times.

EDIT: This is MY review as a paying customer. I am NOT a fan of puzzles, at all. My elderly mother however, is. I purchased this puzzle for her for Christmas as a project for us to work on together considering the challenge. Upon first sight of the puzzle box, my mother was pretty disappointed not to see her usual barns and lighthouses. But once we started in on the very first pieces, she enjoyed it thoroughly and actually turned it into something competitive with who finds the most pieces each day. And as for me, the one who despises puzzles, had a BLAST with this! So if you're not a fan of puzzles, don't let the 'puzzle' factor steer you away. This is unlike any other puzzle out there, if you're up for the challenge. Puzzle was completed in 25 days. The craftsmanship is undeniably the best when it comes to puzzles. If the piece is correct, it'll fit in like melted butter. Even if you think the piece fits and looks right, if it didn't go in place like melted butter, then it's the wrong piece. 'Melted butter' is the best way to describe it. I highly recommend!

I’m on a quest to stump my partner’s mother, who is a die-hard puzzle fiend. This puzzle was a fantastic choice, too, and it was a blast from beginning to end. It was a delight to hand her the box, watch her face contort with conflicting emotions, hear about her progress, then eventually see the finished project.My partner’s mother has a standard MO when it comes to puzzles: organize pieces by color, then shape. I thought I’d get her good with this puzzle, however, which is designed to thwart just such a strategy. It was nice knowing she struggled with this one 😂 It took a few extra days, but she made it through, and now I’m onto the next, most ridiculous puzzle I can find.If you want to give a unique gift, or even just challenge yourself, this is the route to go!

Gave it as a gift to mother and she loves it

I enjoyed this puzzle a lot. My wife and I typically attempt many under 2000 pieces so I was happy to find a smaller puzzle that was still challenging.Unfortunately I let the excitement get ahead of me and preemptively purchased a 20x27 inch frame. After I finished the puzzle I opened the frame and found out that my puzzle is NOT the listed size and will not fit in the frame as it is too long on one side.Note that the box does say "approx" above the inches measurement but even the Amazon listing shows the incorrect size more than once. I'm still satisfied with the puzzle, just not thrilled to have to find another frame.

I haven't yet put this one together. This one took a bit longer to relieve than the first. It shipped from Germany.There was a slight delay in shipping, I was given the option to cancel my order or wait. I chose to wait. Glad I did.

One of the most challenging puzzles I have ever done! I persevered to complete it, but it took a while.
