1. solve a single center

2. solve the opposite center

3. solve another center

4. solve adjacent centers around the cube

__solving the first center__

connect two matching center pieces to make a 1x2 block then connect the other two center pieces in the same fashion and line them up

here we use the first 2 turns to set up the second 1x2 block, then connect the first and second group, then spin the second group around to match the first. This seems like a lot to follow and its harder when all the colors are present on the cube, but just like everything else a little practice makes the first center assembly easy anywhere between 4-6 moves is a good goal for the first center.

__opposite center of the first__

this process is very much the same for the next center, except the moves are a little bit more restricted because of the fixed center, this is acheived with simple set up moves and paying attention to ensure that you don't damage the first fixed center. in these examples the solved center from step 1 will be on the L face.

(Ff)' U' (Ff) F' (Ll)' (Ff) R2 (Ff)' |

__solve another center__

Now we are going to solve one of the remaining four centers, this can be done easily without destroying the 2 fixed centers we have, as long as we are sure to not do any deep twists, (with the solved faces on L and R avoid u or d turns (see the notation page for differences in capital and lower case letters)

now we are going to follow the same idea as the first 2 centers, but since everything we need is on the four faces left (U, D, F, B) we can speed up quite a bit, especially for this first face as we have nothing built in the middle strips (l or r) to interfere. usually the next choice is easy, as a 1x2 block is made already for at least one of the remaining centers.

__solve the adjacent centers around the cube__

now we will work our way around the cube and solve the adjacent centers. The reason we do it adjacent instead of opposites is when you're down to 2 centers left, usually its easy if they are adjacent to each other as opposed to opposite, for solving and recognition purposes. The solved faces are now on L, R, and B. The trick now is to choose the the right order to finish these centers in, this center is really the only decision to be made as after this one it's simple opposite recognition. We know that on either side of the green will be yellow or white, the way to distinguish which goes where is the B-O-Y configuration of most cubes. We know that a corner has those colors in a clockwise order, so using that we can figure out that if green is on the back, that white would be on top, and yellow will be on the bottom, knowing your color scheme inside and out is a necessity for the revenge.

F' (Ll) F' (Ll)' D' (Ll)2 U' (Ll)2 |

here we strayed from our build 2 1x2's method but the construction of this center is still pretty straightforward, we match a 1x2 and put it next to the center piece that was already in place. Then we set up the last center piece so it would connect with the stray center piece, give it a quarter twist to move it out of the way of the set up move, and then bring back the other 1x2.

__solving the final 2 centers__

U2 (Rr) U' (Rr)' |

now this is the hardest wiggle on the last 2 centers, but as long as you don't do any more than 1/4 turns for setup moves, and make sure to do your work in a layer that doesn't have any fixed portions of other centers in it, it will go pretty quick. to see chris hardwick's complete index of final positions for the last 2 centers click here. to see another fast method for solving the centers, check out stefan pochmann's tutorial here.

centers progress gauge | ||

master centers | <20 seconds | you have great recognition and response to easy patterns, first 2 centers should be under 10 seconds, same as the last 4. the really great times will come from a good first two centers. |

intermediate centers | <30 seconds | You can quickly recognize easy patterns and have the responses committed to memory. slow down to see the bigger picture and do more set up moves to reduce move count/increase efficiency. |

beginner centers | 30+ seconds | you can assemble the centers, but it is disjointed and chaotic, not a smooth execution. try practicing the first 2 centers a lot, to train your brain to work like this. also work on smoothness over speed, the speed will come naturally with improved look ahead. |
