I managed to forget most of them after about 5 years of not doing it. I can intuitively get the first two layers now, but the top seems too difficult without knowing the sequences. I like messing about with a Megaminx also, and it's the same for that. I can get the first couple of layers just thinking about it intuitively, but then I get stuck on the top layer. At some point I'll relearn the sequences again, but I haven't yet. Also picked up a 2x2 cube recently, and that one has me pretty stumped. You'd think it'd be easier to figure out but I haven't figured it out yet.
