First 8 edges – Temporarily disturbing the solved centres to match edge pieces and complete 8 edges, placing each solved edge on to the top and bottom layers of the cube.Last two centres – Use commutators and puzzle knowledge to solve one of the last two centres, leaving the last centre solved.

Two adjacent centres – Solve another two centres on the puzzle using the freedom of the 4 unsolved centres on the puzzle.

Opposite centres – Solve the centres of two opposite faces by matching up all of the centre pieces of that colour.

The steps and sub-steps required to solve a cube using the reduction method are as follows: Centres Reduction involves solving all the edges (matching up the pieces from the same edge to make one solved “edge”) and the centres, then solving the cube like a 3x3 (all of the edge pieces have been “reduced” to a single edge, and all of the centres have been “reduced” to one solid colour per face).įor each step a walkthrough will be provided for the 4x4 and 5x5 cubes, as most even-layered and odd layered puzzles share the same properties (4x4 and 6圆, 5x5 and 7x7 etc.). A 3x3 has 1 edge piece per edge and 1 centre per face, whereas a 4x4 has 2 edge pieces that make up one “edge” and 4 centre pieces which make up one “centre”. The method involves a few simple steps that are used to “reduce” the puzzle to the equivalent of a 3x3. The main method used to solve larger order NxN cubes is called “Reduction”, or “Redux” for short. If you can solve the 4x4x4 and the 5x5x5 cubes then you can complete any size, even the 22x22x22 cube or the record-breaking 33x33x33! Start the 11x11x11 Rubik's Cube simulator Reduction Method Overview Once you know the reduction method for the 4x4 and 5x5, you are technically able to solve any NxN puzzle given enough time. These puzzles may appear fairly complex and increasingly difficult as the number of layers increases, however their solutions remain relatively similar. The original puzzle has been expanded outwards to create bigger and more challenging alternatives: the 4x4, 5x5, 6圆 and 7x7. However, the most common of these upgraded Rubik’s Cubes is as simple as it sounds: like the 3x3, but bigger.

Some have changed the shape completely from a cube to a cuboid (and various other shapes), some have only seen simple sticker modifications. Since the release of the original Rubik’s Cube, people have been striving to create new and harder twisty puzzles. Home » Puzzles » Solution of Big NxNxN Rubik's Cubes (4x4x4, 5x5x5.)
