The white centre
Put the four white centre pieces together on the top.
- You start with (input)A scrambled cube
- Result you will get after finishing this stepThe white centre
New moves on a 4x4
A letter on its own, like , is still the outer layer. turns the two right layers together (w for wide). 2R turns only the second layer from the right; the outer one stays. , 2U and 2L work the same way.
How to do it
- A 4x4 has 4 centre pieces in the middle of each face, and they move. This step brings the 4 white centre pieces to the top. Pick the face with the most white already as the top.
- Turn the outer faces (, , , , , ) as much as you like: an outer face only spins its own centre pieces, it never moves one to another face.
- White on a side: turn the whole cube (y) to bring that face to the front, turn until the white piece is top right of the front centre. Turn until a not-yet-white spot of the top is front left. Follow picture 1.
- White on the bottom: turn until it sits front right of the bottom centre, turn as above, then follow picture 2.
- Repeat until the top has all 4 white pieces.
One piece at a time, until all 4 are in

This step: look only for
- Piece
- Centre pieces (1 colour, 4 in the middle of each face)
- Colours
- White
- Where
- The sides and the bottom
- How many
- 4, one at a time
Leave every other piece alone for now: the pictures show them in grey. Found one? Compare it with the cases below.
Which case do you have?
Before you compare and all through the formula: keep the front (the face marked FACING YOU in the pictures) turned towards you. A picture marked BACK, AWAY FROM YOU looks from behind: do not turn the cube, just tilt it to see the back.
