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 doesn’t need to be in its final position yet. Pairing lets you move the group as a single unit 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 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 |
When solving the reduced cube, you may encounter a flipped edge group (OLL parity) or two swapped edge groups (PLL parity). Once you’ve learnt how to solve the reduced cube, you’ll learn how to recognise and fix each case.
4. Check your prerequisite
You should be comfortable solving the white cross, first layer, middle layer, and last layer on a 3×3. If those steps are new, start with the 3×3 course. This course teaches the extra work on the larger cube and provides links back to each shared solving stage.
Watch, then try
Work through an example
Start by stepping through the example one move at a time. This example demonstrates a specific action. Use the lesson’s setup instructions to recognise when that action applies to your own scramble.
Watch one worked example
Watch a two-layer wide turn and its inverse. It moves some of the interior centre pieces as well as the outer layer, unlike an ordinary 3×3 face turn.
Example grip: yellow up · blue front · red right at the start. Follow any written whole-cube rotations.

Drag to inspect other faces. When the cube has focus, use the arrow keys to rotate the view.
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 moves below from left to right. This gives you the starting position for the example. Keep this 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.
Open a 4×4 Digital Cube for practiceThe Digital Cube opens in a new tab so you can keep this lesson open while you practise. Check for yourself whether you’ve met the lesson goal, as the Digital Cube doesn’t assess your result.
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.
