## Solving a 4X4X4 Cube without Algorithms

General discussions and topics

### Re: Solving a 4X4X4 Cube without Algorithms

I'm even closer now: the whole 4x4x4 cube is solved, with the exception of two corner pieces (which are in the same layer but on opposite sides (diagonals)). Once I have solved the cube completely (if I do...), I may post my solution elsewhere, which will include some of the techniques and algorithms I have created/discovered.

Happy Cubing to all.

### Re: Solving a 4X4X4 Cube without Algorithms

Finally, I have solved it!.. after about two months or so (that it, with myself spending about an hour per week). As it happens, I have created an algorithm of my own along the way too; it is used for re-permutating and re-orientating corner pieces, especially when in sets of three. When in sets of three, I am able to reduce the total number of pieces unsolved to just two out of the whole cube.

So anyway, solving a 4x4x4 Rubik's cube without algorithms is definitely possible; If I can do it, then so can you.

Thanks for keeping up with this post.

Congratulations!

Are you going to try to solve any other cubes without algorithms now?

That's amazing! Can you post your steps used and algorithms that you discovered along the way?

### Re: Solving a 4X4X4 Cube without Algorithms

Without the slightest doubt, I will definitely try the other cubes... Most likely the 5x5x5 cube. But, In terms of posting my solution, I need to solve it a couple more times, to be 100% sure that my algorithms work; I am struggling a bit on my third attempt: pairing up the edges is turning out to be a hassle.

I'll update this post soon,
Thanks for keeping up to date!

### Re: Solving a 4X4X4 Cube without Algorithms

As I have now discovered (on my third attempt at solving the 4x4x4 rubik's cube), the problem I have encountered is an Edge Parity. I have managed to solve the whole cube with the exception of two edge pieces which are permutated correctly but not orientated correctly; in other words, it is a pair of edges that have been flipped... somehow. The picture below shows you the arrangement my cube is in:

I have got no idea of how to fix this but, I will soon make the difficult attempt of trying to solve this, intuitively, of course. If I succeed, I will post the solution/algorithm on this post. Also, I am wondering how my 4x4x4 ended up in the arrangement in the first place; if you've got any ideas, please do post a reply.

Thanks for keeping up to date and Happy Cubing!

It's for posts EXACTLY like this that we have a whole forum just for solving puzzles. It's called "solutions".

A 10 second glance will draw your attention to a thread called "How to fix parity on a 4x4 and 5x5", where you can find the solution in video form.

Please do check the forum for more than 1 second before asking for this sort of thing.
Please take off topic discussion off this forum. Thanks.

### Re: Solving a 4X4X4 Cube without Algorithms

I think it ended up like that in the first place because of the edge pairing step itself. I can't say anything more about that though.
Also, to solve it intuitively you can use more commutators! But I don't know how the actual speedsolving algorithm was made.
Good luck!

I haven't used this forum to post or request solutions for solving a 4x4x4 rubik's cube; instead I have used it to make people aware of the ability to solve a Rubik's cube without cheating - therefore there are no algorithms mentioned by myself and if I ever do post any algorithms, I will put them in the Solutions section, respectively.

I hope that clears things up.
