Speedcubes should be turned with fingers.For starting position, the left and right fingers are placed on the left and right layers resp- ectively. The right hand could have 2 starting positions, as shown in the pictures beside.
The gray represents the unnecessary part in this step
The translucent area rep-resents the final position af-terexecuting the movemen
If there's already white edge on the top layer, hide it first and then keep solving forthe Cross
Turn the top layerto match every cross piece one by one, turn 180° to matched down white center pieces. Repeatthis step until all the cross pieces are in the right place.
Cross is actually pretty easy. if you can solve one side you can solve cross too. Do brainstorming:)
If there are no white corner pieces in the top layer, then execute RU'R' or RUR'. Like this case, the green orange white corner piece will place on the top side. After executing the algorithm, it could be solved by following the instruction
If there are no right pieces in the top layer execute the above algorithms in this step, like (R'F'RU)(RU'R'F)
Like this case, the green orange edge will replace bythe top layer, and then follow the instruction to solve
The ( ) in the algorithm only contributes with better fingetricks, and helps with the memorization, which will not affect the turning ofthe algorithm.
This step only requires the yellow side ofthe top , the othersides could be ignored.
There are only four cases in this step, which execute the Algorithm 6 once wil I transform to the next case, until the yellow cross is done.
The diagram is vertical view, and the yellow bars represent the vel low pieces on the sides.
Focus on top side, and there are 7 cases fortotal. The caseswhich only have one yellow corneron the top side just need to execute the algorithm once.
(R U2)(R' U'R U'R')
(R U R'U)(R U2 R')
The other 5 cases require two algorithms7.
The top side will be solved.
Make sure to adjust to the right position before executing the algorithm.
In Step4/5/7, ifthefirsttwo layerswas solved, the case is not included in the instruction, such as eight yellow pieces on the Cop side, oronly two edges need to switch.
These situations indicatethatthe cube is assembled in-correctly, which have to reassemble to the solved state.
CFOP's algorithms areway more than the beginner method, exceptfor the Cross. Cross does not really need algorithms, as itcan be solved byexperience within 8 steps.
In CFOP ,the F2L ( First Two Layers) combines Stel2 and 3, which a pairofcornerand edge can be doneby only one algorithm, with twice efficiency.
CFOP can directly solve the cases in Step 4 by only one algorithm OLLcombines Step 4 and 5, and PLL combines Step 6 and 7, efficient by 200%.
The principle of Algorithm 9 is exchange the position of left and right rear comers.
Pay attention to the direction of L and L.
The diagram is vertical view. The arrows represent the moving direction of the edge pieces, and the black bars representthe same-colored pieces.
M is the movement of middle laver.lt could be done by either index finger or ring finger pushing. M'could be done by ring finger move
