White Cross
The first goal is the white cross and we make this in two steps, first the daisy on the yellow top face, second the White Cross
Our goal in this step
Part 1 of Step 1: We make a “daisy”, where four white petals surround the yellow centre.
first goal
We hold the cube with yellow on top.
(I’ll use for the following examples a cube with U =yellow, F =green that is scrambled by the sequence:R',U',F',R',B,L',D,R',U,B',U,F,
You could use the Gelatinbrain 3x3x3 to follow my sample solution)
This is an intermediate target pattern, because from there we can build the white cross easily. With “white cross” we mean a pattern where the four white edges sit correctly on the white (D) layer. Feel free to turn the whole cube around looking at the different walls, as long as yellow stays on the roof (U layer). In the example diagrams we leave the green face as the F face.
In this first step, the daisy, 4 white edge stickers need to be placed on the yellow U face.
We can locate the four edges with white stickers in the sample diagram: white/red at UF (the usual notation of an edge place is to use the two face names the edge is sitting in), white/green at BL, white/blue at UL and white/orange at FD.
On the yellow face there is no white petal so far.
We can recognize that the white/green edge sitting between the red and blue centre can be moved to the U face either by B’ anticlockwise turn of the blue face) or by L. Only L will place the white sticker on U. We do that and have:
We can recognize a first rule: If a white sticker is in the second layer, turn the non-white face so that the white sticker goes up.
We recognize a second white sticker in the second layer, the White/blue edge at FL.
The move F (the face where the blue sticker – the non-white - is in) brings a second white sticker to U:
We see two more white stickers in the second layers in the F face.
The next move is R to bring the white/red edge to the yellow U face
The last white sticker could be moved up by L’, but at UL there is white/green already. That can easily be changed by doing U’
Now the move L’ can be done:
We have built the “daisy”
Part 2 of Step 1: Finish the white cross
Now, we can send the white edges down by 180 degree turns. We have to match the “wall” sticker with the correct centre. The white/green edge is sent down by F2.
We turn U’ and match the white/blue edge with the blue centre on B.
We send it down with B2. Another U’ matches the white/orange edge with orange centre in R. We do R2.
The last is the white/red edge, currently at UF. We do U and match it with the red wall. Finally L2 completes the white cross.
While building the daisy, very often a case occurs that has not come up in this example: A white edge may be in the cellar (D) layer. Just make sure by turning U that a gap is above the edge cubie in the roof. If the white sticker is in the D face, just send it up by a 180 degree turn. If the white sticker is on a side wall, just do a 90 degree turn and the edge is now in the second layer. You can proceed as above.
Another case is that a white edge is in the roof, but the white sticker is on a side wall. Do a 90 degree turn and the edge is now in the second layer and proceed as usual. Please do some training, before you go on to the next chapter. After a while you will feel quite comfortable with these first two lessons. Many tutorials say: The white cross is trivial or even the white layer is trivial and we just go on to the next steps.
