Hi!

I stumbled into this forum while trying to find out if someone else is using the same "algorithm" for 3x3x3 cube as I am.. Can it be that I'm the only one?

As a teenager, I learned some layer by layer algorithm. But then I lost my cube and there was about 20 years in between before I got a new one. I still remembered how to solve first two layers, but the last layer was completely forgotten.

After some twiddling, I managed to solve it intuitively using only the layer2 edge placement move, "U R U' R' U' F' U F" and it's mirror.. That was the only algo I remembered from the 1980's instructions.

It is possible to reorder the last layer pieces using only that move. I use this order for the last layer:

- Edges to correct position, not necessarily right way around
- Edges correct orientation
- Corners correct position
- Corners correct orientation

I found "Y-Move method" and "Sexy Move method" from you wiki, they are similar but the order is different.. They seem to be more efficient as well.

I now also have 2x2x2 and 4x4x4 cubes. I can solve those too, although I had to cheat and find the parity moves for 4x4x4 from the net..

yep, that's definitely one way to do it. It's not very common at all, but I've seen other cubers learning from old instructions do the same. I'm not sure where to find instructions for it though, as it's not a very efficient way to solve it. I'd recommend watching a tutorial, for example one by a youtuber called Badmephisto (or Dan Brown, his is probably more similar to your method). It might help you remember!


Tervetuloa ihan näin suomeksikin!

Sorry for the slight delay.

I have now learned Petrus method, it's very simple with very few algos to remember. Then I also learned intuitive F2L. Currently I'm fastest if I do intuitive F2L and the last layer cross, but then continue with Petrus instructions step 5: http://lar5.com/cube/fas5.html

I don't understand why most of the "Beginner" instructions go very complex on the last layer? Petrus is much simpler there. You really need only Sune. It does both corners and edges.. Then if you are really interested, learn AntiSune as well and you can rotate the edges differently, possibly saving a few passes.

Oh, and I also made a Rubik robot with Lego Mindstorms..

It was a good challenge to code the algorithm. The "intuitive" steps are difficult, when you actually have to program all possible cases.. I learned a lot myself when thinking about those.

Welcome to the forums!

Once you develop a better understanding of the cube, I recommend checking out the Roux method. It is also mostly intuitive and doesn't have many algs but it has potential to be much faster than Petrus.

Hello @Zuikkis. Welcome to the forum. You could pop over to the Older Cubers Discussion thread and introduce yourself. Lots of us are a similar age to you.
