oll stands for orientation over last layer. in this step we solve the top layer of our cube. for example if we start from the white cross we will solve the yellow side completely in this step
so basically these are the algorithms needed if you have just started out with cfop
so basically since ur at a starting phase ur oll are separted into 2 phases also known better as "TWO LOOK OLL"
the first step is to make the cross
and the second is to solve it . kind of like what we do in beginner method with our starting color
so now here are the algorithms for the first step
ALGORITHM: F ( U R U' R' ) F'
ALGORITHM: F ( R U' R' ) F'
ALGORITHM: F ( U R U' R' ) F'
now that the first part of your oll is done lets move onto the second part of solving the side
here are the algorithms that you will need for this part
this section has 7 cases
ALGORITHM: R' U' R U' ( R' U2 R )
ALGORITHM: L U L' U ( L U2 L' )
ALGORITHM: R' U' R U' ( R' U R U' ) R' U2 R
ALGORITHM: R U2 R2' U' ( R2 U' R2' U2 ) R
ALGORITHM: R2 D ( R' U2 R ) D' ( R' U2 R' )
ALGORITHM: Rw U R' U' ( Rw' F R F')
ALGORITHM: x ( U R' U' L ) U R U' Rw'
so these are all the algorithms for beginner oll
