Six solved centre blocks and twelve fully matched edge groups.
White centre down, yellow up. Treat every centre block and edge group as one large piece.
1. Treat the cube as a 3×3
A whole centre block acts like one centre. A complete three-piece edge group acts like one edge. The actual corner pieces already behave like 3×3 corners.
From now on, use only outer-layer R, U, F, L, D and B turns for the standard solving steps. R turns only the outer right layer. Using Rw in its place breaks up the groups formed during reduction.
2. Follow the same checkpoints
| Order | Target | Instructions |
|---|---|---|
| 1 | White edge groups aligned with centres | Daisy, then white cross |
| 2 | White corners are in place and the bottom row on each side matches its centre | First layer |
| 3 | Middle edge groups match their centres | Middle edges |
| 4 | Four edge groups have yellow facing up | Yellow cross |
| 5 | The top corners have yellow facing up | Yellow corners |
| 6 | Top corners match the side centres | Corner positions |
| 7 | All faces are solved when the remaining edges are in place | Final edges |
Keep your physical 5×5 in its current state when opening a linked explanation. Its pictures show smaller pieces, but the outer-turn relationships are the same. Skip a stage if its checkpoint is already satisfied.
3. Recognise when to leave the ordinary path
Correct 5×5 reduction does not introduce 4×4-style OLL or PLL parity. If you appear to have an impossible 3×3 case, inspect all three pieces of every edge. A reversed wing or unmatched midge means pairing was unfinished; return to the last-edge lessons before continuing. Do not apply the 4×4 PLL repair.
4. Keep your grouped pieces intact
After each algorithm, every centre must still be a single-colour block and every edge must still be a complete group. A single outer turn cannot split a matched group. If any group comes apart, check whether you accidentally used an inner or wide turn in your 3×3 sequence.
The player below reviews the final three-edge cycle. Watch each grouped edge move as one unit. It is one stage of the reduced solve, not a sequence to apply to every reduced scramble.
Need a reminder of the move notation?
R right · L left · U top · D bottom · F front · B back. A letter on its own means a 90° clockwise turn when you look directly at that face. A prime mark (′) reverses the turn. A 2 means 180°. Keep the same face at the front throughout an algorithm.
Rw turns the rightmost two layers together. 2R turns only the second layer from the right. 3Rw turns three layers. x rotates the whole cube like R, so the old front becomes the new top.
Watch, then try
Work through an example
Start by going through the moves one at a time. The prepared example shows a specific action. Use the lesson’s setup instructions to recognise when to apply it to your own scramble.
Watch one worked example
The outer-turn edge cycle works across all 5×5 layers, moving each edge group as a unit. The back group and all corners stay fixed while the other three top groups cycle.
Starting grip. Yellow up · blue at the front · red on the right. Follow any written instructions for rotating the whole cube.

Copy this exact example on your own cube
Start with a solved 5×5, with yellow on top and blue at the front. Apply the setup moves below from left to right to create the example’s starting position. Keep this example separate from the scramble you are solving throughout the course.

Your turn
Follow the linked 3×3 stages in order using only outer turns. Check that centres and paired edges remain intact after each complete algorithm.

If you get stuck
A paired edge comes apart during a 3×3 algorithm.
Check that every standard face turn moved only the outer layer. If you know which wide or inner turn you made by mistake, undo it. Otherwise, restore the centres and edge groups before continuing.
