Solving A 5x5 Rubix Cube
Solving the 5x5 cube is similar (but slightly easier) than solving the 4x4. The process is the same but there are fewer edge cases.
The steps are
- Reduce it to a 3x3 by
- Solving the center
- Solving the edges
- Handle any edge parity
- Solve the 3x3
The center solve is the exact same as a 4x4, just a litle bigger.
- Solve the white square
- Solve the opposite side (yellow square)
- Solve any of the remaining sides
- Solve the adjacent side (it could be any side, but it’s just easier to solve the adjacent side since it means less flipping the cube around)
- Solve the remaining two sides in one go
To speed things up you can use the “free slicing” method. Which pretty much means you solve 8 of the edges w/out making sure you get the center squares resolved after each pass. This just speeds up the process. Once you have 8 out of the 12 edges solved, you put them at the top and bottom and then resolve the center squares. After this, you can solve the remaining 4 edges the “normal” way: one block at a time and always bringing the square faces back to solved after every move.
Flipping an edge
In order to pair up an edge you may need to flip one of the edge pieces. For example, you would want to flip the orange/blue piece in the top right with the bottom right red/green piece. This will let you slot in the blu/orange piece in the next move.

Reading the diagrams
In the diagrams above I use the following conventions.
- The 🔲 square is used to denote a square we don’t care about
- The ⚪ is just a spacer. It means nothing and is only there so everything else lines up.
|is used to denote the side edge of the cube. Something to the left of a
|is on a different face than the square to the right of it.
- The — is used to denote the top edge of the cube. Something above the — is on a different face than the square below it.
Note on notation
Some of the notation for 5x5 is slightly different than the 4x4 or 3x3
Rwmeans “right wide” or the two rightmost columns.
3Rwmeans the 3 right most columns
Rmmeans the “right middle” column. So it’s rotating just the single column between the center colum and the right face.
Lmmeans the “left middle” column.
xmeans to rotate the entire cube so the bottom is now the front and the front is now the top. The two sides (left and right) do not change.
