Occasionally you come across a video that’s so satisfying to watch that your brain never wants you to close the tab. That’s what Dutch puzzle designer Oskar van Deventer has managed to create with this complex web of 19 magic gears that are all somehow able to rotate against each other without completely locking up.
Feliks Zemdegs solved his 5x5 cube at Melbourne Cube Day in 44.837 seconds. And the crowd went not at all wild.
Some of us prefer to relax with activities that turn our brains to goo, while others like to kick back with a real challenge. That’s why puzzles exist, and other brain twisting nightmares like these impossibly complex mazes that took their creator over seven years to draw by hand.
Because apparently a regular-sized Rubik’s Cube wasn’t already enough of a challenge, Tony Fisher built himself a version that’s over five feet long on each side. Even just bringing it out to play looks like a monumental struggle, let alone the back-breaking challenge that is trying to solve it.
This one’s a doozy in that there is a lot going on. The goal is simple, you need to escape a collapsing tunnel with a group of nine people (including yourself). It’s all the other variables that confuse things.
If a UK intelligence agency’s holiday puzzle wasn’t enough to keep you entertained, how about something a little more difficult? This crossword puzzle is based on the computer science language of regular expressions, and it should keep you busy for... some time.
The complexity of a puzzle is usually dependent on how many tiny pieces are crammed inside its box. But by introducing mathematical fractals into the design, this plain nine-piece puzzle by Oscar van Deventer looks like a nightmare to solve.
What better way to celebrate the holidays than a fiendishly difficult puzzle. Well, that’s what one of the UK’s intelligence agencies, GCHQ, reckons—which is why the Christmas card it’s been sending out features this infuriating puzzle. Can you solve it?
The wooden laser-cut dinosaur skeleton is a staple of most museum and science center gift shops. But a company called UGEARS has turned those wooden puzzles into engineering marvels with more gears and moving parts than a Swiss watch.
It’s rather simple if you have the first move. Put your mark in one corner and depending on your opponent’s next move, put your mark on another corner and you’ll be perfectly set up for a win.
God bless the ultra nerds at Coren Puzzle. These Rubik’s Cube enthusiasts built a supermassive 22-by-22-by-22 and made a 90-minute YouTube video about it. In the end, it’s a very sad story.
Derek Hugger is a sculptor, but instead of working in an inanimate medium like clay or marble, his creations are marvels of kinetic engineering made from gears, cams, and a complex assortment of moving parts.
Here’s another classic math riddle for you to prune your brain on a little bit: if people were lined up from tallest to shortest (meaning a person can see everything in front of them) and all wearing black or white hats, can you figure out which color hat you were wearing even if you had no idea how many black or…
Riddles can be fun but can also be really stressful when you start to feel your decently well-wrinkled brain shrivel into a prune. But hey!

The microscopic world is beautiful and fascinating, but those of us who aren’t molecular biologists rarely get to appreciate it. If you need a little more microscopic flair in your life and on your coffee table, you might want to check out these gorgeous, scientifically-accurate puzzles.
Yesterday Australia’s Feliks Zemdegs managed to break the world record for solving a 7x7 Rubik’s Cube in just over two minutes and twenty-three seconds. For those of us who still have trouble just zipping up a jacket, watching him spin and unscramble this cube is incomprehensible.
There’s the satisfaction of placing the final piece, but what other motivation is there really for completing a 2D puzzle? Not much. That’s why these 3D puzzles from Eureka are a better use of your leisure time since you’re left with a surprisingly detailed model car in the end.
