UL/UR — Place the side edges

Step 1: Bring both edges to the bottom

1a. One edge down, one edge between adjacent color corners

Solution U2 M U2 M'

1b. Both edges opposite

Solution M2

Step 2: Solve UL/UR

2. Insert from the bottom

Solution U M2 U'

Special cases

There are two cases where it’s faster to solve UL/UR edges directly instead of bringing them to down layer.

Sa. Edge between opposite color corners

Solution M U2 M' U'

Sb. Edge between same color corners

Solution M U2 M U'

Where to next

• L4E guide — solve the last four edges (the M-slice) and centre, the final LSE step.
