someone hlp me solve the 2x2 ..

Look up some tutorials then

I don't want to follow a pattern to understand it, how did you come to comprehend the blueprint of the cube's movements?

Can you solve a 3x3?

 

[Beginagain]

Can you solve a 3x3?

No, I thought a 2x2 would make the 3x3 easier

 

[Nmile7300]

Not really, it is actually the other way around. Once you solve the 3x3, the 2x2 is just the corners of it. Most people learn the 3x3 first, and unless you are some sort of super genius, you most likely won't solve the 3x3 OR 2x2 without help.

What do you mean by that?

 

[Townes]

I am stuck with the 2x2x2 where I have three yellow on top and cannot fix this corner. Any ideas?

 

[BenChristman1]

The corner is flipped. You just have to twist it back.

 

[Nmile7300]

Yeah you have an impossible state. The corner must have gotten twisted accidentally.

 

[PetraPine]

If you cant twist it back than take the corner apart and put the pieces back into place correctly.

 

[Townes]

That was it, simple fix....thanks a bunch!

I am sub 3 with a bit of 1 looking and CLL. Should I start EG now or wait until I'm sub 2?

Is it worth using PBL algs for adj swap in bottom layer like (R D' R) B2 (R' D R') or should I just cube rotate.
I think if I just practice execution then it has to be faster than doing a z2 or x2 right?

You should learn and use PBL algs for multiple angles. It will make your times faster. Rotations in 2x2 are pretty useless

what about for the longer algs? (adj swap and diag swap)

L D' L F2 L' D L'

For all angle PBL, here's my list which I've genned but haven't completely learnt:

Solved on U, bar in:
B - R' F' R2 U' R' U2 F R U R' F2
L - R2 U' R' U L' U2 R U' R' U2  (x')
R - Don't have this
F* - F R U' R' U' F R2 U' R' U R' F'

Adj on U, bar in:
B - R2 U' R2 U2 F2 U' R2
L - F2 U R2 U2 R2 F2 U' F2
R - F2 U' F2 U2 R2 U' R2
F* - R2 U' B2 R2 U2 R2 U R2

Diag on U, bar in:
B - R' F U' R2 U F' R
L - R2 U R2 U' R2 U R2 U' R2
R - F' R F' R2 F U' R
F* - L D' L F2 L' D L'

Diag on D:
Solved on U* - F R' U2 R U' R' F U2 R2 F R2 F'
Adj on U* - R' U R' F2 R F' R
Diag on U* - R2 F2 R2

The * algs are the ones that should be learnt first and used as a main alg (ie if you have a bar on D, have it on F). Some of them will be slightly pointless/avoidable, so if there are any you don't like, just don't get them.

For adj and diag swaps, Just use different PLLs depending upon the angle

Diag on D:
Solved on U* - F R' U2 R U' R' F U2 R2 F R2 F'
Adj on U* - R' U R' F2 R F' R
Diag on U* - R2 F2 R2

So Instead of 5, one should learn ~20 PBLs

 

[PapaSmurf]

If you wanna be sub 2 maybe, but not really.

I meant a swap on the bottom layer
