Lesson 3 of 9

First layer · Lesson 3

Finish the white layer

Insert all four white corners so the bottom face is white and the bottom row on each side matches its centre.

Before you start

An aligned white cross on the bottom.

How to hold your cube

White down. Rotate sideways to put the empty target slot at bottom-front-right.

1. Choose a corner and find its slot

Find a white corner in the top layer and note its other two colours. A white-blue-red corner belongs between the white, blue and red centres, even if another slot is closer.

Rotate the whole cube sideways, keeping white down, until those two side centres are at the front and on the right. The matching slot is now at bottom-front-right (DFR).

2. Put the corner above its destination

Turn only U until your target corner reaches top-front-right (UFR), directly above its matching slot. The white sticker may face up, towards the front or towards the right. Use the same trigger in all three cases.

3. Repeat the trigger until this corner is solved

R U R' U'

Complete one repetition, then check the bottom-front-right slot. Keep the same grip and repeat without any extra U turns between repetitions. Continue until the target corner is in that slot with white facing down and both side colours matching their centres.

Depending on which way the white sticker faces at the start, you will need one, three or five repetitions. Complete all four moves each time. The other bottom corners and the cross return to their original positions after each full repetition.

4. Bring a trapped corner back to the top layer

If a white corner in the bottom layer is misplaced or twisted, rotate the whole cube sideways to bring that slot to the bottom-front-right. Perform the trigger once to bring the corner into the top layer. Find its matching slot, place the corner directly above it and follow step 3.

5. Repeat with white still on the bottom

After solving one corner, choose the next white corner and rotate the whole cube sideways to bring its slot to the front-right. Solve all four corners. Check the bottom row on every side before moving on. If the bottom face is all white but the side rows do not match their centres, the corners still need work.

Need a reminder of the move notation?

R right · L left · U top · D bottom · F front · B back. A letter on its own means a 90° clockwise turn when you look directly at that face. A prime mark (′) reverses the turn. A 2 means 180°. Keep the same face at the front throughout an algorithm.

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

Follow the white-blue-red corner above the front-right slot. In this prepared orientation, one complete trigger inserts it and restores the white cross.

Starting grip. Yellow up · blue at the front · red on the right. Follow any written instructions for rotating the whole cube.

Another case: White faces up

White faces up

The same corner starts with its white sticker facing up. Keep the same face at the front and perform the full trigger three times to insert the corner.

Starting grip. Yellow up · blue at the front · red on the right. Follow any written instructions for rotating the whole cube.

White faces the front

This orientation requires five full repetitions of the trigger. Pause after each group of four moves, with no extra setup turns between repetitions.

Explain it to yourself

Check your understanding

Where should the corner start before you insert it?

Now use your own cube

Your turn

Find a white corner, name its two side colours, place it directly above its matching slot and insert it. Repeat for all four corners. Check the cross after each insertion.

Open a 3×3 Digital Cube for practice

Opens in a new tab so you can refer to this lesson while you practise. Check for yourself whether you’ve met the lesson goal. The Digital Cube does not grade your work.

If you get stuck

The corner keeps returning to the wrong slot.

Use both non-white colours to identify the matching slot first. Rotate the whole cube to bring that slot to the front-right, then turn U to place the corner directly above it.

The cross is broken after an insertion.

Finish all four moves. If the cross is still broken, check that the fourth move was U′ and that you kept the whole cube in the same orientation during the trigger.

3×3 lesson result — First layer solved. The bottom face is white and the bottom row on each side matches its centre. The middle and top layers are still unfinished.

Your cube at this stage

First layer solved

The bottom face is white and the bottom row of every side matches its centre. The middle and top layers are still unfinished.

Confirm these on your cube. Watching the animation alone does not complete the lesson.
