You can identify corners and choose a white reference corner.
Keep the same face towards you. In the solving lessons, keep white facing down.
1. The letters name the faces as you hold the cube
R is right, L is left, U is up, D is down, F is front and B is back. The letters refer to face positions regardless of colour. Keep the same face towards you throughout the sequence.
On a 2×2, each face turn moves one layer of four corners. The far layer stays still relative to your grip.
2. Suffixes tell you how far and which way
A plain letter means a 90° clockwise turn as you look directly at that face. An apostrophe means a 90° anticlockwise turn. A 2 means a 180° turn in either direction.
| Move | Meaning |
|---|---|
R |
Turn the right face clockwise as viewed from the right |
U' |
Turn the top face anticlockwise as viewed from above |
D' |
Turn the bottom face anticlockwise as viewed from underneath |
R2 |
Turn the right face halfway around |
3. Learn the insertion routine
R U R' U'
Perform all four moves in order, including the final U′. This short sequence is called a trigger. Use it only once the target corner is directly above its slot.
For now, repeat it six times. Six repetitions return the cube to its exact starting state, whether solved or scrambled. Use the drill to check your turns. It does not provide a general solution.
4. Keep turns separate from regripping
Turning U moves only the top layer. Rotating the whole cube changes which faces are at the front, right and back. Later, when twisting the yellow corners, use U turns between corners with no whole-cube rotation. Practise recognising the difference now.
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
Repeat the four-move trigger six times on this scrambled cube. At the end, every piece returns to its starting position. In the next lesson, you’ll start solving the white layer.
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 2×2, with yellow facing up and blue facing you. Apply the setup moves below from left to right to create the example’s starting position. Keep this example separate from the scramble you’re solving throughout the course.

Your turn
Try R then R′, U then U′, and U2 twice. Then repeat R U R′ U′ six times from any starting state and check that the cube returns to that state.
Open a 2×2 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
The drill does not return to the starting state.
Count six complete four-move repetitions, check the apostrophes, and keep the same front face throughout.

Return to the same scramble
Six complete triggers restore the scramble you started with. Begin solving the white layer in the next lesson.
Confirm these on your cube. Watching the animation alone does not complete the lesson.
