The first step is to form a yellow cross on top.
The other side of each
edge piece has to match the adjacent center. Here's how:
- Find the yellow center piece
and hold the Rubik's cube so it's on top.
- Find the yellow & green edge piece and move it to the side with the green center.
- Turn the green side, the side with the green center, a quarter or half turn to get the yellow & green edge piece to the top.
- If necessary, flip the edge piece like this so the yellow side is up.

- Solve the other 3 edge pieces the same way. To prevent solved pieces from getting messed up, use the bottom layer to move pieces around as shown in the
example.
When you have a cross, you're ready to solve the corners.
