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 does not need to be in its final position yet. Pairing prepares a unit that the 3×3 method can move later.
2. Know which pieces can swap 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 pairing it with 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). Once you have learnt to solve the reduced cube, you will learn how to recognise and fix each case.
4. Check your prerequisite
You should be comfortable solving the white cross and the first, middle and last layers on a 3×3. If these steps are new to you, start with the 3×3 course. This course teaches the extra steps for the larger cube and links back to each stage that both methods use.
Watch, then try
Work through an example
Start by going through the moves one at a time. The prepared example shows a specific action. Use the lesson’s setup instructions to recognise when to apply it to your own scramble.
Watch one worked example
Watch a two-layer wide turn and its inverse. A wide turn moves some inner centre pieces along with the outer layer. An ordinary 3×3 face turn moves only the outer layer.
Starting grip. Yellow up · blue at the front · red on the right. Follow any written instructions for rotating the whole cube.

Copy this exact example on your own cube
Start with a solved 4×4, yellow up and blue front. Apply the setup below from left to right. This creates the example’s starting position. Keep this separate from the ongoing scramble you are solving through 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 am trying to solve a white face before grouping 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
Recognise 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.
