I Made a Fully Functional LEGO RUBIK'S CUBE!! (3x3x3)

lego rubik's cube. This is a working 3x3 lego rubiks cube. this fully functional rubiks cube in lego took ages to make, and today I'm trying to improve my old mechanism. If you enjoyed, please leave a like, and subscribe to not miss any content!

FAQ
Q: how do I get all the pieces
A: here is a pieces list, you can buy the entire cube for quite a cheap price. enjoy!

new edit: unfortunately my build got removed, i appealed so it will hopefully be there soon

just go to 'buy parts' to choose how you want to buy it, I'd recommend bricklink

Q: can you put it on lego ideas?
A: if I can improve the design enough so it's reliable I will

Q: when you scramble it by rearranging the pieces, isn't there a chance it won't be solvable
A: yes, I realised this while editing. there's only 1/12 chance

Q: can't you use 2x2 round plates instead of square ones?
A: the circles make it too loose, I've tried this. I have an idea about how to improve that i'll show you if I make another video about this

Q: is someone knocking on my door at 4:03?
A: no, it's just a realistic sound effect, sorry for that

When you "scrambled" it by taking it apart and putting it together randomly, there's a good chance it wasn't solvable due to parity. There's edge parity and corner parity. You have to swap corners in cycles of 3 assuming no edges are swapped, you have to swap edges in pairs of 2 and cannot flip just 1 edge. All corners must be turned in sets of 3 (all clockwise or all counterclockwise) as well. Feel free to reply if you have any questions.

"does this count as an illegal technique"
Buddy. The whole video is an illegal technique.
*It's perfect*

Awesome cube and video! Looks like a huge improvement to the old design; I can't wait to try it out!

[vbregier]

10:50 rebuilding a cube randomly is not scrambling it, you have high chances to get an invalid state (where the solved state is unreachable).

Hands down the best LEGO tutorial creation of the decade! 👏👏👏

Also, that knock at 4:04 sounds EXACTLY like someone knocking on our glass door to our backyard which is ecxactly to my right. it TOTALLY freaked me out. lol

[AE-jofy]

Ok that's legitimately impressive. The inner workings are more complex than what I thought lego was capable of!

[LEGOCOOKING]

this is my first time watching your videos and my mind is BLOWN!!!

[harrasika]

Damn, I remember being both obsessed with LEGOs and Rubik's cubes when I was younger and I spent hours upon hours trying to research on youtube and build my very own LEGO Rubik's cube, but to no success. I thought that it really was impossible as no one had ever done it before. 8 years later you've proven me wrong. This is absolutely awesome.

[RubiksCube]

Wow this is amazing thanks for sharing!

[NipeNipe]

This is a very interesting challenge and represents a great answer. Great build!

[leprechaunne]

You have incredibly well developed spatial reasoning and engineering skills. The way that you identify problems, tinker, and prototype incrementally is all incredible, especially for someone that seems relatively young

I’m a 65 year old woman new to Legos and I can’t even tell you how impressed I am at people’s skill in creating structures like this. The fluid movement of the Cube is awesome!

[Danny-lbdf]

It’s amazing that this is even possible this should be a Lego ideas set I would definitely buy this and the best part is is if you can’t work out how to solve it or throw it at a wall it’s fixable.

Randomly assembling Cube from pieces is a bad idea. There's very little chance that it'll be solvable after it. You should've assembled it with all colors in place and then scrumble it manually.

[levistepanian]

So, I think I understand the issue. The core isn't as found as it should be, so considering a quality of typical Rubik cubes design, you must come up with two improvements: one, make the mechanism more circular. Two, make it springy. Typical speed cubes are loose but springy, so if you can find some perfectly sized springs it will allow for some play. Obviously corner cutting is out of the question but something to make it looser.

I remember trying to build one of these based off a Google image like 7 years ago and giving up after not having enough pieces for two corners.

What leaps and bounds have been made since then, excellent design!

[philippzimmerer]

When you just randomly assemble the cube, there's a 1 in 12 chance it will actually be solvable - so stopping after 1 or 2 layers was likely the furthest you could have gotten anyways ;)

Wow, great work! You have an amazing talent in creating Lego structures, keep it up!
