Block guide

Goal

Do Interchange PAIRs Move or Glue Move, to make the 2x2x1 block and the 2x3x2 block as shown on the right.


Anchor PAIRs

Four pairs placed in the shape shown on the left are called "Anchor PAIRs".

Under Anchor PAIRs, as shown on the right, the pink edge is called "Edge Between Anchor".

Under Anchor PAIRs, as shown on the left, the pink layer is called "Sway Layer".

Under Anchor PAIRs, as shown on the right, the pink layer is called "Lateral Layer".


Prism Base Line

Initially, place 6PAIRs as shown on the left, where the silver center represents the F face, and the black center represents the U face, four of which form Anchor PAIRs

Select two edges that are not on 6PAIRs, shown in magenta below. and 6PAIRs is shown in grey below.

The two edges form the so-called "Prism Base Line", that is,

both edges are Edge Between Anchor, and that layer is shown on the left.

Or both edges belong to Sway Layer, and that layer is shown on the right.


Like the three examples on the left are Prism Base Line.

The example on the right is not Prism Base Line.


All Prism Base Lines can be done with each other with Glue Move. And you can't just use Glue Move to make what was Prism Base Line not.

Skills to complete Prism Base Line

In the two edges you select,

if one of them is Edge Between Archor, on the Lateral Layer X, and the other is on the Sway Layer as shown on the right,
then you can do Interchange Move on X to complete Prism Base Line.

As the example on the left do Interchange Move on F.


if one of them is Edge Between Archor, on the Lateral Layer X, and the other is on the Sway Layer as shown on the right,
then you can do Interchange Move on Y to complete Prism Base Line, where the Y layer is the opposite layer of the X layer.

As the example on the left do Interchange Move on D.


If both are Edge Between Anchor and not Prism Base Line, and that layer is shown on the right,
you can do S2 or E2 turn so that one of them ends up on the Sway Layer, and then do the above skills to complete Prism Base Line.


Tip: You can also integrate it in previous steps. When doing the previous steps, you can place the edges you selected in the relative position to Base 4PAIRs as shown on the right, and then do not do E2 turn until 6PAIRs are completed, and it will be one Prism Base Line.


How to complete the goal

Stage 1
Select the edges to make a Prism Base Line, and select the edges to make another Prism Base Line.
Stage 2
Use the move that does not break Anchor PAIRs to make as one of shown on the left. There is no absolute direction. It does not mean that the orange center must be at F, and the orange center may also be at B.

Stage 3
Using the Glue Move to break Anchor PAIRs as shown on the left, to choose whether the center of F/U is orange/yellow or red/white.
Then the cube will be as shown on the right. There is no absolute direction.

If the center of F layer is selected to be orange, then the 2x2x1 block of the goal will be completed on U layer after.
If the center of F layer is selected to be red, then the 2x2x1 block of the goal will be completed on D layer after.
If the pair was kept on the U layer before, then selecting the orange color in the center of F has a greater chance of being easier to complete the goal.
Stage 4
Do Interchange Move on R, to make the 2x2x1 block and the 2x3x2 block of the goal.

End

Under the restrictions of no breaking the 2x2x1 block and the 2x3x2 block of the goal, 6PAIRs and the base stage, there is only one way to move without going back, and the entire cube can be completed by following that only way.
