How To Solve A 4 By 4 By 4 Rubik's Cube Step By Step Animation
The Rubik'south cube (sometimes misspelled rubix cube) is a mechanical 3D puzzle, invented more than than xxx years ago and however considered as the best-selling toy of all times! Even so, solving the Rubik'due south Cube is considered a nearly-impossible chore, which requires an IQ of 160... Is that really and then difficult? Definitely not!! But follow this simple step past step solving guide and you'll before long find out that yous can solve the Rubik'southward cube also… Let's get to work!
Watch my 7.63s Rubik's Cube solution >>
The mechanism of the Rubik's Cube
Corner piece: has iii dissimilar colour stickers on information technology (there are 8 corner pieces in the cube)
Border slice: has two different color stickers on it (there are 12 border pieces in the cube)
Center piece: has one color sticker on it (half dozen eye pieces, all are attached to the core)
The core is the within of the Rubik's Cube, which holds all the pieces together and is fastened to the center pieces with rotatable axes.
Important! The center pieces are part of the cadre and subsequently cannot move relatively to each other. For that reason they are already "solved". The solving process is actually bringing all corner and border pieces to the "already solved" center pieces (meaning at that place are only 20 pieces to solve out of the 26). For example, the blue center slice volition always be opposite to the green eye slice (on a standard color-scheme cube). Information technology doesn't matter how hard you lot volition try scrambling the cube, it will just stay that way.
Rubiks Cube Motion notations
Move notations are made in club to convey a sequence of moves through writing. When describing the solution we'll employ the post-obit move notations (traditional move notations).
Hither is how it works- every face up given a letter:
- F (front): the front end face (facing the solver)
- B (back): the back face (contrary to the front confront)
- R (right): the correct face
- L (left): the left face up (reverse to the right confront)
- U (upwardly): the upper confront
- D (down): the bottom confront (opposite to the upper face)
The letter ways turning that face ninety°, clockwise (unmarried turn). (e.chiliad. R)
A letter followed by ' (apostrophe) means turning that confront 90°, counter-clockwise (single turn). (east.g. R')
A letter followed by "2" means turning that face 180° (double turn). (e.g. R2)
For example: executing [ F R' U2 ] in a row looks that fashion:
A sequence of moves is called an algorithm.
(If yous're having difficulty in finding the CW/C-CW direction of a face (like B or D), temporarily twist the cube so that face will become the F face which is the easiest face up to determine the cw/ccw direction.)
Don't be worried about it, you'll easily become used to these move notations. Likewise, all the algorithms are followed by animations like the i of the last example (only if animations are turned on).

Stop of Intro.
The Rubik's Cube Solution
Solving the Rubik's cube is fabricated piece past piece, but like whatsoever other puzzle. Therefore the solution is divided into steps each of which solves number of pieces without destroying the ones completed on previous steps. Let's start!
In this step we have four pieces to solve. First choose a color to begin with. I chose white in this guide. For this fourth dimension, cull the white as well, so the images along the solution will exist relevant to your solving process. In addition, it is all-time to start with the white/yellow colors as they are the easiest colors for quick recognition which is of import for speedsolving.
Retrieve! Bring the white border pieces to the white heart, and not the white centre to the edge pieces.
The post-obit examples cover all possible cases for this footstep:
(solution is below the prototype/animation)
[ F2 ]
[ U' R U ]
[ F' U' R U ]
In this pace nosotros'll solve the four corner pieces of the meridian layer.
Inserting a corner slice to its solved position is done this way:
First notice an unsolved white corner (at the lesser layer), and position it under the place it should exist solved into (past doing D moves). So continue equally follows:
The following examples cover all possible cases for this step:
[ F D F' ]
[ R' D' R ]
[ R' D2 R D R' D' R ]
Echo that for the other three corners.
Solving a corner that its white sticker is in opposite to the upper face up (the third case above), is washed in two steps. The first is orienting the corner so the white sticker will show on one of the side faces (done by- R' D2 R D), and so Solving using the second instance solution (R' D' R).
If a white corner piece is located on the tiptop layer merely in the wrong place (see wrong paradigm above) or incorrectly oriented in its place, merely insert a non-white corner there, and past that the white corner piece will go back to the bottom layer. And so solve information technology correctly.
In this step nosotros'll solve the 4 edge pieces of the middle layer, and by that we'll really complete the beginning 2 layers (a.k.a F2L).
In order to insert the edge piece into its position we'll use one of the following algs:
[ U' 50' U L U F U' F' ]
[ U R U' R' U' F' U F ]
(These are mirror algorithms which basically does the same. Ane is for border pieces which are to the right of the solving position and the 2nd is for those on the left)
Repeat that for the other iii edge pieces.
In a instance that an edge piece is in its right position but incorrectly oriented (come across prototype), insert a incorrect edge slice to this position, and as a consequence the wanted edge piece volition go back into the superlative layer. Then solve information technology correctly using the suitable algorithm.
In this step, for the first fourth dimension we won't completely solve the pieces only merely orient them correctly. In other words our step goal is to form a cross shape on the upper face of the cube. The edge pieces exercise not need to fit the colors on the sides.
There are only four possible orientation states:
Country 1
State 2
Country 3
State 4
In society to complete this stride (reaching country iv) we'll use the following algorithm:
This algorithm promotes the cube one state alee each execution.
Meaning that executing this alg once, on state 1 will promote the cube to state 2, and and then on. Therefore, we'll take to apply this alg 1-3 times to complete this step. (Animation note: await for the algorithm to finish earlier clicking "play" again, call up to turn the upper face twice yourself (U2) before the final execution).
Pay attention! Executing this alg from the correct angle (angle of the cube in your hands) is crucial. For example, in state 3 it's important to execute this alg when the ii correctly oriented border pieces are facing to the back and left faces, and not to the front\right faces.
In this stride our goal is to permute the four final layer corner pieces.
Pay attending! Our goal is merely to position the corners in their correct place; we don't have to orient them correctly. For example, take a expect at the prototype to the right; the xanthous-green-red corner slice is well permuted. 
In this step at that place are only 2 dissimilar possible unsolved states:
- When ii well permuted corners are side by side to each other.
- When two well permuted corners are diagonal to each other.
If you lot can't observe 2 well permuted corners, turn the upper face (U) until they'll show up. They must be there.
In gild to complete this step we'll utilise the following algorithm: (Proceed reading before executing)
[ L R' U' R U L' U' R' U R ]
This algorithm rotates 3 corner pieces counter-clockwise, and leaves the 4th corner untouched.
If you take 2 adjacent well permuted corners- turn the upper face up one time clockwise (U). That move will reposition the corners into a state of affairs which only one well permuted corner volition remain while the other three corners needed to be rotated counter-clockwise. Now but execute the algorithm above, and by this unmarried execution you really completed this step (remember to execute this algorithm from the correct bending – when the well permuted corner is on the dorsum correct. see algorithm paradigm above).
If you have 2 diagonal well permuted corners- just execute this algorithm above once (the angle doesn't matter), and by that, your cube state will alter into a two adjacent well permuted corners state. Then follow the two adjacent corners instructions higher up.
In this pace our goal is to orient the four corner pieces of the last layer, the ones nosotros take just permuted.
In lodge to practice so we'll employ the post-obit algorithms:
[ L U 50' U L U2 L' U2 ]
[ R' U' R U' R' U2 R U2 ]
These algorithms really practice the same thing, just in an contrary direction. The starting time algorithm orients three corners clockwise, while the 2nd orients iii corners counter-clockwise. For that reason you tin learn only i of them if you lot adopt (executing one alg twice equals to executing the 2nd in one case).
If you take only one well oriented corner (like in the alg images), then you are lucky - just execute the suitable alg one time and finish this step.
If you lot have two well oriented corners or no well oriented corners, execute one of these algs randomly from dissimilar angles until you'll go just one oriented corner, then just execute the suitable alg one more than time to consummate this stride.
In this step our goal is to permute the last layer edge pieces into their correct position, and past that to completely solve the Rubik's cube.
For that, we'll use the following algorithms:
[ R U' R U R U R U' R' U' R2 ]
[ R2 U R U R' U' R' U' R' U R' ]
Just like the previous step algs, these algorithms actually exercise the same thing, only in an opposite direction. The first algorithm rotates three edges counter-clockwise, while the second rotates three edges clockwise. For that reason you'll accept to learn only one of them if you adopt.
In this step in that location are just two possible states:
1 correct border piece, or no correct edge pieces.
(Of-course likewise- all edge pieces correctly positioned can occur- and that means the cube is already fully solved..:) Congratulations! )
If you have one solved border slice, then execute the suitable algorithm in a higher place and by that really consummate the whole Rubik'southward Cube!
If yous take no solved edge pieces, so execute one time, one of the algs above (the angle doesn't affair), and by doing that, one of the edges will go solved. Then solve using the suitable algorithm.
Congratulations!! You did it! Go on practicing the solution until yous'll exist able to solve the Rubik's cube without looking at the algorithms (memorize them), I promise yous it will happen sooner than y'all think!
