The examples below show the four basic cases: These initial 1x1x2 blocks are very easy to make. The first 1x1x2 block can either be built with a D-face edge or a mid-slice edge.īecause there is freedom to fully rotate the R and U faces without breaking anything up, Is then placed into the correct mid-slice position (FL/BL/FR/BR) and connected to its block by To build a 1x2x2 block a D-layer corner and two edge pieces are needed (a D-face edge and a mid-slice edge).īuilding the block involves first building a 1x1x2 block with the corner and one edge piece.

In general the 1x2x2 block should always come before its connecting 1x1x2īlock, otherwise more moves will be required later. The order of execution depends on the situation. In order to reduce this step into bite-sized chunks which can be recognised and executed quickly, the step is split into four parts:

Because all edgesĪre now oriented it is possible to complete this stage using just R, U and Līack to Main Page Basic Block Building Strategy This stage completes the first two layers by building two 1x2x3 blocks onĮither side of the Line made in the previous stage.
