The 20 number is for the hardest scrambles possible. That's the most ANY cube will take. Of course there's plenty of combinations you can solve in less, even in competition with their minimum scrambling standard (as in they won't give you a cube that can be solved in 2 or 3 moves, lol. They have procedure for scrambling to make sure this doesn't happen. You'll still only need 20 moves max if you're in "God's realm" or potentially less if it's an easier scramble.)

Just a tip, i wouldn't suggest going straight from beginner method to something like Fridrichs method right away (F2L, OLL, PLL). Because that is WAY to big of a skill level jump. Id suggest learning maybe 4 out of the 7 OLL algorithms and all the PLL algoirithms and skip F2L cause it can be confusing. So instead you do cross, corners, edges, OLL, PLL. Which is an easier transition from cross, corners, edges, cross, corners. Jumping straight to F2L, OLL, PLL is difficult.

Whether to count a half-turn as one move or two, is a question where a case can be made either way. Simliarly, a case could be made for counting a slice move (turning the central "slice," which is equivalent to turning opposite faces in parallel), or even an anti-slice move (turning opposite faces equal amounts in anti-parallel), as a single move, since these can be done in essentially one motion.

That's the difference between the smallest number of moves that any particular scramble can be solved in, which as you pointed out is of course 1, and the smallest number of moves in which it's possible to solve any scramble, which is the topic of the video. It's tricky to define this difference in English with so few words, which is why in maths we have symbols like 'forall' and 'exists', and why the order you write them in matters.

@numberphile My college,IIT Bombay holds the current Guinness World Record for most people solving Rubik's cubes simultaneously.937 people successfully solved their cubes in the given time and I was lucky enough to be one of them.

Oh, it makes sense now, of course it does... I don't even know why I got confused the first time. "it is the MINIMUM number of moves necessary to complete the most complicated "scramble" of the Rubik's cube" but it is "the MAXIMUM number of moves it takes to solve a Rubik's cube." Thank you stranger for clearing things up for me.

ots weird i do nor like math but you guys make it so much more interesting!!!

Brady, I hope that you'll be at the record breaking event and give us a video afterward for those of us that cannot make it please.

I've never owned a Rubik's cube, nor had the desire to, but this is making me want one.

That would be the exact same 20 move algorythm, since a superflip flips ALL edges, it would look just like a 3x3x3 with huge centers and edges.

@numberphile Hi Brady, are you considering making any videos on other Rubik's puzzles (like bigger cubes, or other shapes)?

That charity event should be on skype (or similar), and everyone with a rubik's cube and a webcam should all get together online and solve their cubes!

What's particularly convincing about this is that some manuscripts said 616, which also works to get Nero's name, just in a slightly different spelling.

The current World Record for fewest moves competition (FMC) is 16 moves, which was in fact the optimal moves needed to solve the cube in question. Only 1 in 473 cubes can ever even be completed in 16 moves.

42 is the answer to the greatest question of Life, The Universe and EVERYTHING.

I'm curious to know that now that we know the god's number, was there a way to calculate this from knowing its a 3x3x3 cube, that can then be applied to other size rubix cubes?

Did anyone know where I can get the educational resources about the cube that Matt promises?

I read all the comments - well, most of them!

The record for the Rubik's Cube done in fewest moves is now 20 moves! Done by Tomoaki Okayama in japan this year.

And that's excellent.

If you do a quarter turn then again the same quarter turn of the same side, it counts as one half turn, since you made those moves one after another. Notice that those moves affect same way on a cube. It is so called hall turn metric, where each quarter or half turn is measured as one move.

The new world record for a cube solved in least moves in a competition is 20 set by Tomoaki Okayama.
