  2. Rotate the again face clockwise.
  3. Rotate the highest layer counterclockwise again to its unique place.
Rotation Objective
Prime layer clockwise Align the nook with the slot on the again face
Again face clockwise Insert the nook into the slot
Prime layer counterclockwise Return the highest layer to its unique place

Repeat this course of for the remaining two prime corners. As soon as all three corners are solved, the highest face of the dice will likely be full.

Step 5: Clear up the Prime Edges

Now that the highest face is full, let’s give attention to arranging the 4 edge items round it. These edge items ought to match the colour of each the highest face and the aspect face they’re adjoining to.

Observe the highest face and find an edge piece that isn’t in its right place. Let’s assume the orange-blue edge piece must be moved to the front-right place.

Insert the sting piece into the second layer, dealing with the entrance. Rotate the entrance face clockwise till the sting piece is aligned with the right-side face. Then, rotate the fitting face clockwise to insert the sting piece into the highest layer.

To accurately orient the sting piece, it’s possible you’ll must carry out a selected sequence of strikes:

Edge Piece Orientation Transfer Sequence
Blue aspect dealing with entrance D R’ D’ R
Orange aspect dealing with entrance D’ R D R’

As soon as the sting piece is accurately inserted and oriented, repeat the method for the remaining three edge items till all 4 edges are solved.

Step 6: Clear up the Prime Face

The highest face of the dice ought to now be fully solved, with all 9 heart items and edge items of their right locations. If not, comply with these steps:

Align the Nook Items

Rotate the highest face till one of many unsolved nook items is within the front-right place. Orient the nook piece in order that its right place on the highest face is dealing with you.

Insert the Nook Piece

Carry out the next sequence of strikes:

Sequence Description
R U R’ U’ Transfer the front-right nook piece to the fitting after which again
R U2 R’ Transfer the nook piece to the again after which again to the entrance

Clear up the Edge Items

Repeat the above steps for every unsolved edge piece. Rotate the highest face till an unsolved edge piece is within the entrance place. Carry out the identical sequence of strikes (R U R’ U’ for the left edge, R U2 R’ for the fitting edge) to insert the sting piece.

Orient the Edge Items

If any of the sting items are oriented incorrectly, carry out the next sequence of strikes to flip it:

Sequence Description
U R U’ R’ Flip the entrance edge piece

As soon as all the highest face items are solved and oriented, you’ve efficiently accomplished Step 6 of fixing the Rubik’s Dice.

Step 7: Permute the Prime Edges

The following step is to permute the highest edges. Which means that you need to organize the highest edges in order that they’re all within the right positions. To do that, you will have to make use of the next algorithm:

Algorithm Description
R U R’ U R U2 R’ This algorithm strikes the highest edge that’s on the entrance of the dice (the one with the inexperienced sticker on it) to the fitting.
L’ U L U’ L U2 L’ This algorithm strikes the highest edge that’s in the back of the dice (the one with the purple sticker on it) to the left.

You should utilize these algorithms to rearrange the highest edges till they’re all within the right positions.

After getting permuted the highest edges, you should have accomplished the seventh step of the Rubik’s Dice answer. You are actually one step nearer to fixing the dice!

Step 8: Orient the Prime Corners

Now that you’ve got positioned the highest corners, it is time to orient them accurately. This entails aligning the coloured faces of the corners with the corresponding faces of the center layer. To do that, use the next algorithm:

Algorithm:

Step Transfer Sequence
1 R U R’ U’ L’ F R F’ L

With this algorithm, you’ll insert one nook at a time into its right place and orientation.

Suggestions:

  • Begin with any nook that’s misplaced.
  • Apply the algorithm slowly and exactly.
  • Repeat the algorithm till all 4 corners are accurately oriented.
  • If you happen to make a mistake, do not panic. Simply undo the algorithm and begin once more.

As soon as all the highest corners are oriented, you’re one step nearer to finishing the dice. Within the subsequent step, you’ll learn to place the highest edges.

Step 9: Clear up the Backside Cross

After getting solved the highest layer, the following step is to resolve the underside cross. This entails matching the sting items on the underside layer to the middle items on the corresponding sides. To do that, you need to use the next algorithm:

Algorithm:

Step 1: Rotate the entrance face till the sting piece you need to resolve is on the front-right nook.
Step 2: Rotate the underside face clockwise as soon as.
Step 3: Rotate the entrance face counterclockwise as soon as.
Step 4: Rotate the underside face counterclockwise thrice.
Step 5: Rotate the entrance face clockwise as soon as.

Repeat this algorithm till all 4 edge items on the underside layer are solved.

Orientation Examine:

After finishing step 4, verify if the sting piece is inserted accurately by its orientation. If the colours of the sting piece do not match the middle items on both aspect, apply the next orientation algorithm:

Step 1: Rotate the entrance face clockwise as soon as.
Step 2: Rotate the entrance face counterclockwise twice.
Step 3: Rotate the entrance face clockwise as soon as.

Step 10: Clear up the Backside Corners

With the underside face solved, it is time to deal with the underside corners. Every nook piece has three sides, and they need to match the colours on the adjoining sides of the underside face.

Matching the Corners

To match a nook, maintain the dice with the underside face dealing with you. Find a nook piece with one aspect matching the colour on the underside face. If it would not, rotate the highest face till it aligns.

Positioning the Corners

After getting a nook piece with an identical aspect, it’s essential place it accurately. Use the next steps:
