One-Answer 2x2x2 Question Thread

[BenChristman1]

Hey everyone,

I recently got a 2x2 a few days ago and now I average about 12 seconds, as I found that many 3x3 algs transition to 2x2. However, when learning PBL algs for 2x2, I came across this case which I could not figure out how to solve. I solved red first, then orange on the top. I tried using the alg R U' R F2 R' U R' but it did not work. How would I solve this case? Also, one more question, do some PBL cases require you to flip the cube upside down to solve them?

Thanks.

As @OreKehStrah said, you should never have to rotate to do a PBL. To do that case (double adjacent swap), turn the U face so both bars are in front and do this alg: R2 U’ B2 U2 R2 U’ R2

Thanks, that alg really helps!

Sorry about this, but I have one more question. How would you solve this PBL case? I drew it out.

For this one you could either flip it so that the adjacent swap is on top and the diagonal swap is on the bottom (with the bar in the front), and do R U’ R F2 R’ U R’, or you could learn an alternate alg. JPerm has a whole playlist dedicated to 2x2 where you can learn these cases and some alternate algs.

Oh, so you would need to flip the cube for this PBL case. Thanks for the clarification! And I will be sure to check into Jperm's video.

Chris Olson's videos on 2x2 are very good. You can find them here: https://www.youtube.com/playlist?list=PLRZHt_6umybxomCRUVl7X17tfGOZLDNa9

Is there any good 2BLD thread on the SS Forums?

There’s a 2BLD example solve thread, but I’m not sure if there is a normal discussion thread. You’d have to search the forums a little bit to find it, though.

What is the name of the method where you solve CP-line followed by finishing the D layer and doing one of the <RU> gen CLLs?

See speedcubedb.com. this is the one bar in bottom front case. I do R' D R' F2 R D' R since flipping the cube is very slow, though idk if my alg is the best.

(y') R2 U R2 U' R2 U R2 U' is ridiculously fast

That's Diag-Adj btw (Diagonal-Adjacent)

(y') R2 U R2 U' R2 U R2 U' is ridiculously fast

That's Diag-Adj btw (Diagonal-Adjacent)

yeah but requires a whole cube rotation which takes away from the fast execution

I usually do D. I just executed it (with the D) 12 times, and it was a .88 average. I average .6 doing it without the rotation

did you timing try the R' D R' alg? it takes some practice and might not be faster

That doesn't solve it; it leaves it in a diag bottom. I'm pretty sure it's supposed to be executed with the bar in the front, which kinda defeats your point of not using rotations/D moves

it does have bar in front. unless I read the diagram wrong

It has it in the back. The top means it's in the back, the bottom means it's in the front (I'm pretty sure)

 

[qwr]

yeah it's swapping the back two which means bar in front

 

[ProStar]

Oh wait yeah you're right

 

[qwr]

Oh wait yeah you're right

so try timing it. I'm not very good at executing rn but I think I could get faster at it because it's regripless
