What is it with humans that makes us love to take on a challenge at our own leisure? Like, instead of spending a rainy day lying on our back and looking at the ceiling, we choose to do something that terrorizes our brain a good deal? You know, like grabbing a carton of pieces from the world's hardest puzzle, pouring them all out, and submitting ourselves to the challenge. When you think of it, it does sound kinda weird, right? Well, weirdos or not, we share the passion for hardest puzzles, and this is our list naming some of the cool jigsaw puzzles you'll have a hard-yet-pleasurable time assembling.

As you're about to see, these jigsaws aren't just hard because of their weird-shaped pieces. They are hard because of the images they display, too. Take, for instance, the jigsaw puzzle depicting intersecting lines. Like a million of them! Or the brainteaser puzzle where you have to assemble a gorgeous image of very charming fried beans. Now that's truly something!

So, get ready and scroll on down below to check out our submissions to the title of the hardest puzzle ever! Have you assembled any of them? If so, do let us know in the comments! And hopefully, you'll still find some new and cool puzzles to torture your brain with.
