How to Solve a 4x4 Rubik's Cube

The 4x4 has NO fixed center pieces! We reduce the 4x4 into a 3x3 in 3 reduction steps.

Step 1: 4x4 Centers→Step 2: Edge Pairing→Step 3: Parity Algorithms
1

Step 1: Solve 4x4 Centers (2x2 Center Blocks)

No fixed center pieces exist on 4x4!
Phase 1

Your goal is to build a 2x2 block of 4 center stickers for all 6 colors. Since the centers can move, you MUST respect standard color ordering: White opposite Yellow, Green opposite Blue, and Red opposite Orange.

Standard WCA Color Layout:
  • White is opposite Yellow
  • Green is opposite Blue
  • Red is opposite Orange

Step 2: Pair 4x4 Dedges (Edge Pairing)

Combine pairs of matching edge pieces into 12 single edge blocks
Phase 2

Locate two matching edge pieces on opposite sides. Use slice-flip-slice algorithms to join them together without destroying your completed centers.

Step 3: Solve as 3x3 + Fix Parity Errors

Special cases that only happen on even-layered cubes!
Phase 3

Once centers and edges are paired, solve the cube using standard 3x3 algorithms. On a 4x4, two special parity errors may occur:

OLL Parity

OLL Flip Parity (Single Flipped Edge)

One edge pair is flipped upside-down on the top yellow cross (impossible on a 3x3):

Rw2 B2 U2 Lw U2 Rw' U2 Rw U2 F2 Rw F2 Lw' B2 Rw2

* Wide moves (Rw, Lw) turn two outer layers together. See Move Notation.

PLL Parity

PLL Swap Parity (Opposite Edges Swapped)

Two opposite edge pairs need to swap places after the rest of the cube is solved:

r2 U2 r2 Uw2 r2 Uw2

* Lowercase r turns inner slice only. Lowercase Uw turns top two layers.
