It took Ernõ Rubik more than a month to solve his namesake puzzle the first time. Today, competitive cubers can best the classic brain teaser in less than five seconds, and casual players can do it in minutes. Their not-so-secret weapon is math. Devising or memorizing sequences of moves that accomplish a particular goal--for instance, swapping two corners--is key to cracking your Rubik's Cube. When game designers start stacking more layers onto a standard 3-by-3-by-3-square cuboid, it doesn't change those algorithms much; it just makes the solve mega-tedious.
If you look away from this Rubik's Cube-solving robot for even a second, you'll miss history. The Sub 1 Reloaded cracked the notorious puzzle in just 0.637 seconds earlier this year, smashing its own mark of 0.887 seconds and setting the Guinness World Record. The robot is the pride and joy of German engineer Albert Breer, who boosted its puzzle-solving power by adding a new Infineon chip. Feliks Zemdegs holds the fastest time for a human, coming in way behind the machine at a sluggish 4.73 seconds.
There's the way we plod along trying to solve the Rubik's cube... and then there's speed cubing. Rubik's cube champion Feliks Zemdegs shared a video of solving the puzzle in a scorching 3.81 seconds -- quicker than his previous world record time of 4.73 seconds.

Humans may have gotten pretty adept at solving Rubik's Cubes, but as usual, the machines are coming for us! This machine, invented by Ben Katz and Jared Di Carlo (humans!) can solve a Rubik's Cube in roughly half the time of the previous world record, and they claim it can "definitely go faster." A video posted to Katz's YouTube channel shows the machine solving a cube in 0.38 seconds. Seriously, if you take a particularly luxurious blink, you'll miss it. The video slows down to 25 percent of the speed and eventually 3 percent of the speed to show exactly how the machine isolates sides and flips them into place.
