Most difficult puzzle in the world: which one is this?

The most difficult puzzle in the world is the 'Colour Changing PuzzleFrom the brand "Clemens Habicht Colour Puzzles," released in 2017. This is an extremely difficult 1000-piece jigsaw puzzle. This puzzle is so incredibly challenging because the colors of each piece constantly change depending on the angle you look at it from. And: many of the pieces have the same shape and seem to fit in multiple places. This is truly the most difficult puzzle ever createdHere's a sneak peek in a time-lapse video:

One color puzzles and pieces have the 'same' shape

These are puzzles that consist of a single color and whose pieces have the "same" shape. And then the same in the sense of standard puzzle pieces. There are also puzzles where each piece has a unique shape, these are the so-called "Krypt" puzzles – these are even more challenging.

Transparent puzzles

With transparent puzzles, you can see through the pieces; there's no color to connect them. You simply have to work with the shapes of the pieces.

Puzzles with only one picture

These are all puzzles that only have one image, for example, a 1000-piece puzzle with the same fish depicted multiple times. Or a single type of flower depicted multiple times. This makes it difficult because each puzzle piece looks the same.

Krypt Puzzles – One color puzzles with puzzle pieces that each have a unique shape

The Krypt puzzles are Ravensburger puzzles, and these puzzles have only one color and nothing else—so one all-black or all-white puzzle. They become even more challenging because each puzzle piece has a completely different shape. So, many more variations are possible.

Rainbow puzzles (Gradient puzzles)

Rainbow or Gradient puzzles are puzzles with a color gradient, often featuring almost all the colors of the rainbow. While you can still solve puzzles based on color, I can tell you it's quite challenging!

Holographic puzzles

Holography is a technique for creating a three-dimensional representation of an object. This has also been done with puzzles, making them very challenging because you can't solve by color, as the color of the puzzle piece actually changes when you look at it from different angles. This category includes the world's most difficult puzzle. There are also holographic puzzles that aren't necessarily difficult to solve, but are holographic when you move them. For example, animals or people appear to move on the puzzle.

Globe puzzles

The well-known globe puzzles, naturally shaped like a globe. Not necessarily the hardest in the world, but quite challenging. Certainly harder than a "regular" puzzle. So, it definitely belongs in this list of very difficult puzzles.

Greatest puzzles in the world

When is a puzzle the hardest, in terms of how long it takes you? You can also go for the largest puzzle in the world, consisting of 54.000 pieces – 'Journey through Art' by Grafika. That must take you a long time. Maybe that's the most difficult puzzle in the world? Or if you choose a puzzle from 51.300 of 33.600 Pieces – that's also quite time-consuming. It's not the hardest to lay, but it will definitely take a long time!
