You can solve a 3×3 using the beginner method.
Inspect the cube from every side before choosing a front.
1. Build a simpler puzzle inside this one
Reduction means grouping the extra pieces so that the whole cube behaves like a 3×3. First build six solid 2×2 centres. Then join the matching edge pieces into twelve complete groups. Finally solve using only outer face turns.
A grouped edge can still be out of place at this stage. Pairing creates a single unit that you can move later using the 3×3 method.
2. Know which pieces can trade places
Each centre block contains four movable centre pieces. There is no fixed middle sticker to tell you its colour. Each edge contains two wing pieces, and the eight corners provide a reference for the colour scheme.
A wing has two colours. Check both colours before deciding whether it matches another piece. Two wings make a complete 4×4 edge.
3. Keep the solving stages separate
| Stage | Finish this before continuing |
|---|---|
| Centres | Six uniform blocks in the correct colour order |
| Edges | Twelve complete two-piece groups, with centres restored |
| Reduced solve | Use the 3×3 method with outer turns |
While solving the reduced cube, you may encounter a flipped edge group (OLL parity) or two swapped edge groups (PLL parity). After you learn to solve the reduced cube, you’ll learn how to recognize and fix each case.
4. Check your prerequisite
On a 3×3, you should be comfortable building the white cross and solving the first, middle, and last layers. If these steps are new to you, start with the 3×3 course. This course covers the extra steps for the larger cube and links back to each stage the two methods share.
Watch, then try
Work through an example
Start by going through the example one move at a time. It shows a specific action from a prepared position. Use the lesson’s setup instructions to recognize when that action applies to your own scramble.
Watch one worked example
Watch a two-layer wide turn and its inverse. An ordinary 3×3 face turn moves only the outer layer. This wide turn also moves some of the centre pieces in the inner layer.
Example grip: yellow up · blue front · red right at the start. Follow any written whole-cube rotations.

Copy this exact example on your own cube
Start with a solved 4×4, with yellow on top and blue at the front. Apply the setup below from left to right to create the example’s starting position. Keep this practice setup separate from the scramble you’re solving throughout the course.

Your turn
Find one 2×2 centre area and one two-piece edge. Count the pieces in each. Review the 3×3 path if you cannot yet complete a 3×3 solve.

If you get stuck
I’m trying to solve the white face before grouping the edges.
Begin with centre blocks only. Pair the edges next. The white cross and corners come during the reduced 3×3 solve.

Identify centres and wings
Recognize the movable 2×2 centre blocks and the two wings in each edge. Nothing needs to be solved yet.
Confirm these on your cube. Watching the animation alone does not complete the lesson.
Check off each item once you can do it yourself.
