For the uninitiated, the Rubik’s Dice could seem to be an insurmountable puzzle, a colourful enigma that defies logic and mocks the solver’s intelligence. Nevertheless, with a scientific strategy and a little bit of apply, anybody can grasp the artwork of fixing this iconic puzzle. This complete information will give you a step-by-step tutorial, breaking down the method into manageable chunks, and arming you with the data and strategies to beat the Rubik’s Dice in simply 20 strikes.
To start our journey, let’s set up a typical floor by understanding the essential notation utilized in Rubik’s Dice fixing. Every face of the dice is referred to by its preliminary letter: F (entrance), B (again), U (up), D (down), L (left), and R (proper). Moreover, we use apostrophes to indicate counterclockwise rotations and no apostrophes for clockwise rotations. With this notation in thoughts, we will dive into the primary stage of the answer, which includes fixing the white cross on the highest face.
As soon as the white cross is full, we transfer on to the second stage, which is fixing the white corners accurately. This stage requires a bit extra finesse and introduces a brand new approach referred to as “inserting with AOLL.” AOLL (Adjoining Orientation Final Layer) refers back to the algorithms used to orient and insert the sting items of the final layer, and we’ll cowl these algorithms intimately within the upcoming sections. By fastidiously following the steps and practising these strategies, you’ll step by step progress by way of the levels of the answer, finally reaching the satisfaction of fixing the Rubik’s Dice in simply 20 strikes.
Resolve the Backside Layer
1. Place the Cross
Orient the sting items on the underside layer in order that their colours match the middle items. Begin with the white edge piece and insert it into the slot between the white and purple heart items. Rotate the face equivalent to the adjoining heart piece (on this case, yellow) to align the opposite edge piece and insert it.
2. Transfer the Nook Items to the Backside Layer
Find a nook piece that isn’t on the underside layer however has its appropriate shade on the underside. Orient the piece in order that its backside face (the one with the proper shade) faces you. Rotate the highest face of the dice till the piece is aligned with its appropriate place on the underside layer. Insert the piece by turning the adjoining aspect of the underside layer (e.g., should you’re inserting a yellow-green-red piece, flip the inexperienced aspect).
Repeat this course of for the remaining three nook items. If a nook piece is within the fallacious place on the underside layer, rotate the highest layer till the piece is aligned with its appropriate slot. Then, maintain the nook piece with one hand and rotate the underside layer to insert it.
After inserting the 4 nook items, the underside layer needs to be full.

Align the Facet Edges
Upon getting accomplished the primary two steps, you’ll need to align the aspect edges of the dice. This may be achieved by following these steps:
-
Maintain the dice in order that the solved aspect is dealing with you. Discover an edge piece that isn’t in its appropriate place. This piece could have two colours that don’t match the colours of the middle items on the solved aspect.
-
Find the place the place this edge piece ought to go. The proper place can be on the identical aspect of the dice as the 2 colours on the sting piece.
-
Use the next algorithm to insert the sting piece into its appropriate place:
Algorithm Description R U R’ U’ Rotates the fitting face clockwise, strikes the sting piece up one place, rotates the fitting face counterclockwise, and strikes the sting piece down one place. L’ U’ L U Rotates the left face counterclockwise, strikes the sting piece up one place, rotates the left face clockwise, and strikes the sting piece down one place.
Repeat these steps for the remaining three edge items till all the aspect edges are aligned.
Place the Nook Items
As soon as the sting items are in place, you possibly can transfer on to positioning the nook items. This may be achieved in two steps:
Step 1: Place the nook piece within the appropriate layer
- Maintain the dice with the nook piece you need to place dealing with you.
- Flip the highest layer to line up the sting of the nook piece with the proper slot on the center layer.
- Insert the nook piece into the slot by turning the highest layer in the other way.
Step 2: Orient the nook piece accurately
As soon as the nook piece is within the appropriate layer, it’s essential orient it accurately in order that the colours match the adjoining edge items.
There are two circumstances to think about:
- The 2 adjoining edge items are the proper shade: Rotate the highest layer within the route of the arrow till the nook piece is oriented accurately.
- One of many adjoining edge items is the wrong shade: Carry out the next algorithm to flip the nook piece (see desk under):
Algorithm R U R’ U’ R U2 R’
Orient the Final Layer Edges
The following step is to accurately orient the sides of the final layer. This includes rotating the sides till their colours match the facilities of the adjoining faces.
To do that, maintain the dice with the unsolved face dealing with you. Find an edge piece that isn’t accurately oriented. If the sting piece is on the highest face, carry out the next algorithm:
R U R' U' F U F'If the sting piece is on one of many aspect faces, carry out the next algorithm:
R U R' U' L' U LRepeat this course of till all the sides are accurately oriented. As soon as the sides are oriented, you possibly can transfer on to the subsequent step.

| High face | R U R’ U’ F U F’ |
| Facet face | R U R’ U’ L’ U L |
Permute the Final Layer Edges
8. Commuting Edges
If two edges must be swapped, they are often commuted utilizing the next algorithm:
“`
R U2 R’ U’ R U2 R’
“`
This algorithm will swap the 2 edges within the final layer, however it is going to additionally rotate the highest layer by 90 levels. To appropriate this, carry out the next algorithm:
“`
R2 D’ R U2 R’ D R’ U2 R
“`
This algorithm will rotate the highest layer again to its authentic orientation whereas preserving the swapped edges.

Orient the Final Layer Nook
Upon getting three of the 4 corners oriented accurately, you possibly can orient the final nook utilizing the next algorithm:
Step 1: Maintain the dice with the accurately oriented corners within the entrance and proper positions.
Step 2: Carry out the next sequence: R U R’ U’ R U2 R’
Step 3: This sequence will rotate the misplaced nook 180 levels, orienting it accurately.
Step 4: Repeat this sequence till all 4 corners are oriented accurately.
Tip: If the misplaced nook is within the again left place, carry out the sequence D L D’ L’ D L2 D’ L’ as an alternative.
