How to solve a 6×6 cube
Solve the centres, group each four-piece edge and reduce the 6×6 to a familiar 3×3—then deal with the parity cases unique to even-layer cubes.
The same reduction idea—with more pieces
A 6×6 is solved using the same overall method as a 4×4 or 5×5. Build each 4×4 centre, combine each group of four edge pieces, then solve the reduced puzzle as a 3×3.
Once you understand these ideas, the same approach scales to cubes of any larger size.
Solve the six centres
Centre solving follows the same bar-building process used on a 5×5. The difference is that every centre is now a 4×4 block and there is no fixed centre piece to identify the face colour, so keep the standard colour scheme in mind.
Build one complete centre
Pair centre pieces into bars, then insert the bars beside one another until the first 4×4 centre block is complete.
Solve the opposite colour
Build and insert bars using slice–turn–slice sequences, exactly as on a 5×5. Restore every displaced inner slice after inserting a bar.
Work on the front face
With the first two centres protected on the sides, build a third centre on the front using the same four-bar technique. Check the colour scheme before committing to it, then repeat the process for the fourth centre.
Solve the final two centres together
As on a 5×5, the last two colours are solved at the same time. Build the bars on the left, use familiar slice moves to complete the third bar, then finish the final misplaced pair with a commutator.
Build the remaining bars
Keep the completed centres protected while transferring bars between the final two faces.
Use the finishing commutator
This sequence moves the final centre pieces without disturbing the centres already completed, This guide uses 2R for only the second slice from the right and 3R for only the third slice. Inner-slice notation is not completely standardised, so the notation diagrams show exactly which layer to turn. Rw and 3Rw always mean wide turns of two and three layers respectively.:

Pair the twelve edges
Each 6×6 edge contains four pieces. Pair them with the same free-slice method used on a 5×5: match pieces in a working slice, store completed groups on the left and right, then restore the slice.
Because a 6×6 has two pieces on each side of an edge’s centre line, the final two edges can contain two independent parity types: one affecting the outer wings and one affecting the inner wings.
Do not rush into a parity algorithm
If the inner pieces of an edge remain unsolved, you can recognise that parity before the 3×3 stage. However, solving it immediately may mean performing another parity algorithm later.
Instead, begin the 3×3 stage with a cross colour opposite the affected edge. In this example, solve either the white or orange cross, then continue until the parity pattern is fully visible.
Finish the 3×3 stage and solve parity
Once the edges are grouped, solve the reduced cube as a normal 3×3. At the last layer, inspect which part of the affected edge is flipped and choose the matching algorithm below.
Turn inner slices only for R and L moves

Turn only the second slices

Turn three layers together
Here, the complete edge group is affected. Turn all 3 right or left layers for each R or L move in the algorithm:

Quick parity reference
| What remains flipped? | Layers used | Recognition |
|---|---|---|
| Inner-wing parity | 2R + 3R | The central pair within the four-piece edge |
| Outer-wing parity | 2R | The two pieces nearest the outside stickers |
| Full-edge parity | 3Rw | All four pieces of the reduced edge |
