Beginner F2L: Insert a Corner–Edge Pair

Before you start

You can consistently solve a 3×3 with the beginner method.

How to hold your cube

Hold the cube with the white cross facing down and the pair’s empty slot at the front-right.

1. Change one part of your method

F2L stands for first two layers. Instead of solving all the white corners and then all the middle layer edges, solve a corner and its neighbouring edge together. Keep using the beginner method for the cross and last layer while you learn F2L.

Each pair belongs in one slot between two side centres. For front-right, choose the white corner containing the front and right colours, and the edge containing those same two side colours.

2. Recognise a pair that’s ready to insert

In the first case, the corner and edge are already joined in the top layer. Their adjacent side stickers form a bar of the same colour, and the pieces are oriented so the pair is ready to insert into its slot.

Use the cube net for the example’s starting position to locate the white-blue-red corner and blue-red edge. Check both colours on the edge and all three on the corner. Don’t assume two neighbouring pieces make a useful pair just because one colour matches.

3. Insert the prepared front-right pair

R U R'

R opens the slot, U brings the pair over it, and R′ closes the slot with both pieces in place. The white cross is restored, and the corner and edge are solved together.

This three-move insertion works for the specific pair shown. It won’t join pieces that are scattered around the cube. If your corner and edge are separate, use the beginner corner and edge insertions for now, then return to this example for practice.

4. Add cases gradually

Practise spotting a pair that’s ready to insert during your usual solves. Learn how setup turns line up the pair above its slot before looking for shorter algorithms. Once you’re comfortable with this case, use the CubeSkills intuitive F2L lessons for more examples of how to form pairs.

This lesson introduces F2L. You can keep using the rest of the beginner method as you learn.

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

The white-blue-red corner and blue-red edge are already connected. Watch R U R′ insert both into the front-right slot.

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 3×3, with yellow on top and blue facing you. Follow the setup moves below from left to right to recreate the example’s starting position. Keep this example separate from the scramble you’re solving throughout the course.

R U' R'

Then follow the lesson sequence. If your cube has a different colour scheme, use your own colours to identify the corresponding pieces.

Check your understanding

Now use your own cube

Your turn

Recreate the example’s starting position on a solved cube. Follow the joined pair as it moves, then insert it. Compare solving the slot with the pair to inserting the corner and edge separately.

Open a 3×3 Digital Cube for practice

The 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

R U R′ doesn’t solve the pair I picked at random.

The pieces must already be joined in the same way as in the example. For other cases, use the beginner insertions or study the setup instead of repeating this sequence.

Your cube at this stage

A corner and edge solved together

The front-right corner–edge slot is solved and the white cross is intact. Another slot in the middle layer is still unsolved in this example.

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

I can identify the corner and middle edge belonging to one slot.I can recognise the joined pair in this example.I understand that this insertion works for one F2L case, so it won’t work for every pair.
