So is the standard Rubik’s cube so easy that you’re bored with it? Can you solve it in 12.1 seconds?
Well, try your hand at a 4D Rubik’s cube.
Then, if your head hasn’t exploded, check out the 5D Rubik’s cube! From the site: “In the spirit of taking things too far, here is a fully functional 5-dimensional analog of Rubik’s cube.”
Sadly, 5 people have already solved the 5D cube. You can’t be first.
