Alright, thanks. My first usable 2x2 (Witwo V1) is in the mail. As you might guess I dont have much experience with the 2x2. I suppose I'll learn CLL for 2x2 first and use that knowledge with the 3x3.

What is god's number on 15 puzzle? I found out that the lower bound is 109 multi-tile moves. Has it been found yet?

Wiki:
"For the 15-puzzle, lengths of optimal solutions range from 0 to 80 single-tile moves or 43 multi-tile moves."
From the article cited in wiki (A. Brüngger, A. Marzetta, K. Fukuda and J. Nievergelt, The parallel search bench ZRAM and its applications, Annals of Operations Research 90 (1999), pp. 45–63.):
"Six positions required exactly 80 moves, 4 of them have previously been detected by Gasser [12]. The new ones are (15, 14, 13, 12, 10, 11, 8, 9, 2, 6, 5,
1, 3, 7, 4, 0) and (15, 11, 13, 12, 14, 10, 9, 5, 2, 6, 8, 1, 3, 7, 4, 0). The computation proves that the hardest 15-puzzle positions require exactly 80 moves to be solved."

Is there a 4x4 centres only scrambler anywhere? Prisma and qqtimer don't have it, and google doesn't turn anything up.

Would Fabric dye work the same as RIT dye on plastic?

Interesting idea, why don't you test it on a crappy cube if you have one and see. I don't know anyone who's tried it.

The only problem is that it's a bag of Black dye that's been lying around the house for a long time and I don't have any crap cubes that aren't black to test it on.

Hey guys, can anyone give me any tips on memorizing Megaminx LL algs, and recognizing easier? Like, are there any methods anyone uses to recognize easier? I have the Dayan megaminx with Ridges, and the stickers are really bad (brightness wise), and I'm getting some new ones soon, but yeah, besides constantly practising, any amazing tips? Thanks in advance guys

Why would you need a centers only scrambler for 4x4? It's the first step, so it would mess up the edges anyway wouldn't it? (Both Reduction and Yau)

Maybe for praticing BLD?

Ok but still, why not scramble the usual way? Or are centers not the first step in BLD?
Regardless, you still have to memo the centers with the other pieces scrambled
Cage method, maybe?

My idea was that maybe centers are made after edges(i wouldn't think that).
Then it would make sense to only scramble centers so you could practise them. If the edges are messed up after finishing centers, you would know you made a mistake. If the edges were scrambled, you wouldn't be able to tell.

It still redirects me to the russian url site.
Works for me.
It seems their server has blocked you? I dunno.
You can try another sim, but I'd recommend this one since it's the one almost everyone here is using.
Try this:
