3 Bar was so simple that I guess I didn't even write about it. Just went on to 3 Bar Clock. To this point in the Bandage Kit adventure some form of Corners First has worked well with most of them. Maybe all of them. Even 3 Bar. But not 3 Bar Clock. I had to use the 3x3x2 Corner Piece Series to get the corners. But after getting the corners, then what?!? The middle layer was easy enough but I had to 3-cycle the last 3 edges on top and didn't see how to do that. Well, the answer was obvious. Solve it just like a 3x3x2. Edges first. Then corners. It is a bit more complex because of the 1x2 tile I held on top. But it worked.
I've solved the 3 bar a few times now but probably just by luck. I solve yellow face first (is that right) and then move on to the white face. But I don't know how to cycle the corners on the last face. Could you help me out?
ReplyDeleteIt has been years since I solved it. I will have to build it and use what I have said in this post to see if I can recall. Just to be clear, we are talking about 3 Bar, not 3 Bar Clock, right? It sounds like my key to 3 Bar was using a corners first approach. It may take awhile to figure out. Let me know if you are still interested, or if you have moved on. Thanks.
DeleteAlex, when I first posted this in 2012 I evidently used a Corners First approach. Today I built it, scrambled it and solved it that way. It requires some tricky set up moves but it is doable. Here is what I think. 1) get all the yellow corners on one side. 2) get them all in the right places using one of two algorithms. R2 U R2 U2 F2 U F2 is one of them but you have to do some extra work in the middle somewhere do deal with the bars so you can do the F2 moves. I know I am not explaining exactly how to do it at this point. The other algorithm that may be used to permute the corners is R2 U R2 Ui R2 U R2 Ui R2. What I would do if I were you is get a solved 3x3x3 and do each of these algorithms. Do one, look at how many adjacent corners are paired up, do it again. Do that several times. Then do it with the other algorithm. I should mention that the edges get jacked up a bit in this process, but that is ok—it is a corners first method after all.
DeleteOnce the corners are solved you can use setup moves and M2 U2 M2 U2 to solve all the edges. If two bars need flipped at the end and the given algo won't work, try R2 U2 R2 U2 R2 U2 where the bars are on R and U.
Alternately, I've noticed that in the chart I made in the summer of 2014 I say I solved this puzzle much like a 3x3x2. I do that edges first, then do the corners.
Much simpler solving as a 3x3x2! So Alex, if you want a hint, I'd say solve the edges, then the corners, like a 3x3x2.
