# Thread: Big Cube BLD Discussion

1. hey i said that is there any 4x4 BLD Tutorial and textbased one?..... no any answer :/

Seriously? It's been an hour.

3. So in one week, IŽll get back home and IŽll try 4x4x4 and 5x5x5 blindfolded for the first time with the third method I learned, so, hope IŽll get it !

4. I've solved maybe five 444 blindfolded, my best is 9:22 and now I noticed that I've got problems with centers. I solve centers with U2 method and it's very nice, because it's so easy to understand. But I have to use inner slices all the time so my execution time is very long. I start after memo at 4 minute and I end it probably at 8 :/ It is TOO LONG. Maybe it is better to do L Lw' instead of l' ? How do you execute with U2?

5. I agree - 4 minutes just for centers isn't ideal. Consider using comms. Move count gets halved that way

6. I've only just started working towards 4BLD and I found that comms for centers are not that hard.
It helps a little when you already know commutators though.

Two good resources:

7. This is a discussion, right?

I just realized Daniel Tammet would be amazing at big cubes blind if he tried, learned to cube, learned blindfold solving.

This has already been discussed fairly heavily in other threads on this forum. I think one of the best posts about this was by Stefan here. My suspicion is that if Daniel were good enough to be decent at the cube-solving part of it, and if he were motivated, he could be fairly decent at big cubes BLD, but I suspect it would take him an awful lot of focus and years of effort to match Marcell Endrey's recent awesome 5x5x5 BLD record. I seriously doubt he has a significant innate advantage over Marcell (or even me) for big cubes BLD.

(And by the way, much congratulations to Marcell - it's an incredible achievement!)

9. I've got a problem with 555 bld. Everything I do as in 444, inner edges with M2 method, but I don't know how to execute inner centers. Friend told me to use this comm:

l E l' U2 l E' l' U2 and the inversion.

But it's very hard to make setups of it to some cases. Can somebody help me and find easier way to solve it? I doesn't have to be commutators, it can be 1-piece algorithm.

10. You can use U2 for T-centers. It is similar to U2 for X-centers (that is, centers that 4x4x4 has), but a bit more complicated because of some exceptions.

Anyway, you can use not only l E l' U2 l E' l' U2, but l U' l' E* l U l' E* (where E* = E, E' or E2), S' U' S u* S' U S u*, or even M d2 M' U2 M d2 M' U2, tons of them.
