5x5 (Professor's Cube)

Step 1 — White Center

Build the white 3x3 center grid by making three 1x3 bars.

• Middle Bar

Pair the white center piece with 2 White inner-edges to make a 1x3 line.


• Side Bars

Make two separate 1x3 bars on adjacent faces (1 corner-center + 1 edge-center + 1 corner-center).


• Assemble

Slide the side bars onto the White face to form a complete 3x3 block.

Step 2 — Yellow Center

Flip the cube so White is on the bottom.

• Middle Bar

Build a yellow bar on the top face while preserving the white center using: Rw and U


• Second Bar

Build a yellow bar and move it to the top face while preserving the white center using: Rw U2 Rw'


• Last Bar

Make the last yellow bar and align it under an existing top bar to finish the 3x3 yellow center by also using: Rw U2 Rw'

Step 3 — Side Centers

With White on the left and Yellow on the right, solve the 4 middle centers around the sides.

• First 2 Centers

Solve the first two centers using the Rw U2 Rw' bar-insertion logic.

• Last 2 centers

We nee to make only two corner center pieces remain to be swapped by usin: Lw' U2 Lw U Lw' U Lw.

Step 4 — Edge Pairing

• Free Pairing (First 8 Edges)

Place matching edges on the front-left and front-right slots and check if they line up or not.

• If they line up


Slice inner layers to form a complete 3-piece edge → Store it in the top layer → Replace it with an unsolved edge → Unslice to fix centers.


• If they don't line up


Apply the Flipping Algorithm: R U R' F R' F' R



Then slice inner layers to form a complete 3-piece edge → Store it in the top layer → Replace it with an unsolved edge → Unslice to fix centers.


• Last 4 Edges

When no unsolved top/bottom edges remain, place matching pieces on the same horizontal row and use slicing and flipping turns to join them directly without breaking centers.

Step 5 — Fix The Parity (If Needed)

A 5x5 Rubik's cube edge parity happens when pairing the last edges and one single edge piece remains flipped or mismatched.

Step 6 — Solve Like a 3x3

Turn only the outer layers (R, L, U, D, F, B) and solve the rest of the cube like a standard 3x3!
