The world record for the fastest-solved Rubik's Cube is 5.66 seconds, set last year by Feliks Zemdegs. When you see a speedcuber like Zemdegs do his thing, you realize that he is approaching the puzzle in an entirely different way than you would.

That goes double for watching Marcell Endrey, who just set the world record for finishing a Rubik's Cube blindfolded, which is now 28.8 seconds. Watch Endrey complete this remarkable feat at this week's Zonhoven Open.

As you can see the Zonhoven officials take no chances, and there was a guy holding a piece of paper between Endrey's blindfolded eyes and the cube to ensure it was legit.

Endrey, a 20-year-old from Hungary, also held the European record for the fastest blindfolded 4x4 Rubik's Cube. (I think we have a pretty good idea of what Endrey likes to do with his free time.)

Four by four cubes have an additional row on each side, which makes them significantly more difficult to figure out. Here is Endrey knocking out a 4x4 blindfolded in under five minutes.
