Algorithm to get from top dot to top cross?

[SebCube]

Hey Everybody

Ive noticed that during cubing when solving the top cross sometimes there is no L or Bar/Line there's only the dot and a couple of corner pieces to fix this all i do is the algorithm for the Line and that will get me to the cross but that takes about 2 more seconds and 2 seconds can cost you so i was wondering if there is an algorithm to get it to the cross. :confused:

Try the Wiki. =)

F R U R' U' F' Fw R U R' U' Fw'.

W stands for wide and means you turn two layers.

EDIT: Speedcubing Discussion is not the place to ask questions. =)

You can do any of the 'dot' OLL cases. Any of them will orient all the edges.

There is the dot sune, which I like. r' R2 U R' U r U2 r' U M'.
There is also the dot H, which I also like. R U2 R2 F R F' U2 R' F R F'.

Sure, just rotate the cube 180 degrees (or do a U2, whichever's faster for you) and replace all the F turns in F R U R' U' F' with fs (that is, double layer turns).

Do F R U R' U F. AUF until you have the L, then do F R U R' U' R U R' U.

An algorithm for this I like is: (R U2) (R2' F R F' U2') (R' F R F')

If you bother learning this, why not just learn the full OLL for all the 'dot' cases.

It is not really worth finding algs to turn a 3-look dot case into a 2-look dot->cross->corner OLL case.

Maby he still uses a beginners method where OLL is not a step, the last layer for him may consist of:
1. Orientate cross
2. Permute cross
3. Position corners
4. Orientate corners

f R U R' U' S' R U R' U' F'

Forget the cross, just solve the dam thing.

R U2 R2' F R F' U2 R' F R F' or

F R U R' U' F' f R U R' U' f' depending on dot type.
