Six solved centres and eleven fully matched three-piece edges.
Put the mismatched three-piece group at top-front (UF). Its midge is the reference.
1. Recognise the final wing mismatch
Eleven edges must already be complete. The last group may have both wings reversed relative to the midge: the outer two stickers match each other, but the middle sticker is the other edge colour. You see the opposite checkerboard on the other face.
This is a swap of the two wings, not a single sticker flipping in place. If several groups are still unpaired, return to ordinary pairing first.
2. Place that group at top-front
Rotate the whole cube to put the affected group at UF. Keep its midge as the orientation reference. Compare all three stickers on each of the two sides with the prepared starting net before beginning.
3. Use the 5×5 version exactly
Rw U2 x Rw U2 Rw U2 Rw' U2 Lw U2 3Rw' U2 Rw U2 Rw' U2 Rw'
Work through the sequence in these groups.
Rw U2 xRw U2 Rw U2 Rw' U2Lw U2 3Rw' U2Rw U2 Rw' U2 Rw'
Rw and Lw turn two layers. The only 3Rw′ comes after Lw U2 and turns the rightmost three layers. x rotates the whole cube in the direction of R. Use the new face directions after the rotation. Complete the final Rw′ before inspecting the cube.
4. Return to reduction checks
Every edge should now have a bar of three matching stickers on each of its two faces, and all centre blocks should be solid. Reorient the cube for the standard solve, then proceed to the next lesson, which uses outer 3×3 moves.
A correctly reduced 5×5 has no additional 4×4-style last-layer OLL or PLL parity. If an apparent exception appears later, inspect your grouped edges rather than applying the 4×4 algorithms.
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 wings at UF do not match their midge. Watch for the single three-layer 3Rw′ after Lw U2. All other Rw moves use two layers.
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.
Rw U2 Rw U2 Rw' U2 3Rw U2 Lw' U2 Rw U2 Rw' U2 Rw' x' U2 Rw'Then follow the lesson sequence. If your cube’s colour scheme differs, match the piece relationships using your own colours.
Compare the starting position and the result
Drag each cube to inspect its other faces.

Your turn
Compare the final group’s two wings with its midge on both faces. If it matches the parity case, perform the full 5×5 repair and recheck every edge group.

If you get stuck
I used the 4×4 version and the final edge is still wrong.
The 5×5 sequence uses 3Rw′ at the point where the 4×4 version uses Rw′. Compare the notation for that move and count three layers.
More than one edge is still incomplete.
Return to ordinary pairing. This case assumes eleven complete groups and only one reversed-wing group.

Your cube at this stage
All twelve edges complete
All three pieces of every edge match and the centres are intact. The groups can now be solved with outer 3×3 moves.
Confirm these on your cube. Watching the animation alone does not complete the lesson.
