How to Use the 4×4 Solver

Paint your Revenge Cube's current state onto the 3D model, press Solve, and follow the step-by-step instructions to reach a solved state.

1
Pick a Color from the Palette

Use the color palette in the top-right corner. Select from the 6 standard colors: White, Yellow, Red, Orange, Blue, and Green.

2
Paint All 96 Tiles

Click on any tile to paint it. Use the rotation arrows to reach all 6 faces. Each face has 16 tiles (4×4 grid). Paint every tile to match your physical cube's scrambled state exactly.

3
Verify Your Colors

Each color must appear exactly 16 times across all faces. The 4×4 has no fixed centers — the solver uses the 4 center tiles per face to determine orientation. Double-check before solving.

4
Hit "Solve!" and Follow Along

Press Solve! to validate and compute a solution. The 4×4 solver may take a few moments due to the puzzle's complexity. Follow each move in playback mode using Next and Back.

About the Solver

Our 4×4 solver uses a reduction-based approach — it first pairs centers and edges to reduce the puzzle to a 3×3-equivalent state, then applies the Kociemba algorithm. Solutions typically require 40–60 moves and may take a few seconds to compute due to the 7.40 × 10⁴⁵ possible states.

Understanding Move Notation
  • R, L, U, D, F, B — Outer face moves (same as 3×3)
  • r, l, u, d, f, b — Inner slice moves (second layer)
  • Rw, Lw, Uw — Wide moves (outer + inner layers together)
  • ' suffix — Counter-clockwise; 2 suffix — 180°
Tips for Accurate Painting
  • The 4×4 has 4 center tiles per face — paint them first to establish each face's identity.
  • With 96 total tiles, take your time and rotate frequently to verify all faces.
  • If you get an error, a color likely appears more or fewer than 16 times.
  • The solver handles parity errors automatically — just paint what you see.
About the 4×4×4 Revenge Cube

Invented in 1981 by Péter Sebestény, the Revenge Cube has 56 visible pieces and 7.40 × 10⁴⁵ possible states. It's infamous for parity errors — situations impossible on a 3×3 that require special algorithms. The world record is 16.79 seconds by Max Park.
