When making the moves below hold your cube full-face front with logo on wrong position, then do either one of the sequential moves, and it will move to the . I recently downloadd your Middle School book Rubik's Cube STEM Unit. The activities are outstanding and my students are so excited to complete each one. Hundreds of schools compete at solving cubes as a group and classes create really cool mosaic designs too. We even have ongoing mosaic contests each year.

A basic understanding of the Rubik's cube that will set you up nicely for the rest of the video guides. This stuff is Once you can do this, there's no stopping you, so pay attention. .. Download on our PDF guide on how to solve to Rubik's cube. The You Can Do The Cube book was among the first Rubik's Cube solution guides and sold more than million copies so there's a chance that your parents. One way to do this is move the four white edge pieces down to the opposite These instructions will take you through the process of solving a Rubik's cube, no .
The most common deviation from Singmaster notation, and in fact the current official standard, is to use "w", for "wide", instead of lowercase letters to represent moves of two layers; thus, a move of Rw is equivalent to one of r.
It was used e. Lowercase letters f b u d l r refer to the inner portions of the cube called slices. An alternative notation, Wolstenholme notation,  is designed to make memorising sequences of moves easier for novices.
This notation uses the same letters for faces except it replaces U with T top , so that all are consonants. Addition of a C implies rotation of the entire cube, so ROC is the clockwise rotation of the cube around its right face.
Middle layer moves are denoted by adding an M to corresponding face move, so RIM means a degree turn of the middle layer adjacent to the R face. Singmaster notation was not widely known at the time of publication. Horizontal planes were noted as tables, with table 1 or T1 starting at the top.
Vertical front to back planes were noted as book, with book 1 or B1 starting from the left. Vertical left to right planes were noted as windows, with window 1 or W1 starting at the front.
Fridrich method : The fastest Rubik’s cube solution for 3x3x3
Using the front face as a reference view, table moves were left or right, book moves were up or down, and window moves were clockwise or anticlockwise. Many general solutions for the Rubik's Cube have been discovered independently. After sufficient practice, solving the Cube layer by layer can be done in under one minute. Other general solutions include "corners first" methods or combinations of several other methods.
In , David Singmaster and Alexander Frey hypothesised that the number of moves needed to solve the Rubik's Cube, given an ideal algorithm, might be in "the low twenties". It is similar to the layer-by-layer method but employs the use of a large number of algorithms, especially for orienting and permuting the last layer.
The cross is done first, followed by first layer corners and second layer edges simultaneously, with each corner paired up with a second-layer edge piece, thus completing the first two layers F2L. Fridrich's solution requires learning roughly algorithms but allows the Cube to be solved in only 55 moves on average.
A now well-known method was developed by Lars Petrus.
One of the advantages of this method is that it tends to give solutions in fewer moves. For this reason, the method is also popular for fewest move competitions. Next, the corners of the top layer are solved. The cube can then be solved using only moves of the U layer and M slice. The easiest layer by layer methods require only 3—8 algorithms. The cross is solved first, followed by the remaining edges, then five corners, and finally the last three corners.
The user has to set the colour configuration of the scrambled cube and the program returns the steps required to solve it.
There are a number of speedcubing competitions that take place around the world. However, the single best time of all tries is also recorded. The World Cube Association maintains a history of world records. In addition to the main 3x3x3 event, the WCA also holds events where the cube is solved in different ways:  Blindfolded solving  Multiple Blindfolded solving, or "multi-blind", in which the contestant solves any number of cubes blindfolded in a row  Solving the cube using a single hand  Solving the cube with one's feet  Solving the cube in the fewest possible moves  In Blindfolded Solving, the contestant first studies the scrambled cube i.
Their recorded time for this event includes both the time spent memorizing the cube and the time spent manipulating it. The event is scored not by time but by the number of points achieved after the one hour time limit has elapsed. The number of points achieved is equal to the number of cubes solved correctly, minus the number of cubes unsolved after the end of the attempt, where a greater number of points is better. If multiple competitors achieve the same number of points, rankings are assessed based on the total time of the attempt, with a shorter time being better.
In Fewest Moves solving, the contestant is given one hour to find a solution and must write it down. Example: solving the 4th center piece. Solution:[ r' F r ] Explanation: by doing an r' move you will bring down the upper-right yellow center piece on the top face into the front face now it will adjacently match the center piece on front face , then an F move to align both pieces on the right side of the front face, and finally an r move to bring them both upwards into the top face, and form a complete yellow center block.
If the yellow piece on the front face were on a different position in the front face out of the 4 possible positions , you could just make some F turns to adjust it. Same goes for the top face.
I kept the instructions short for this part, as it's an intuitive part. Just take some time to practice the movements of the 4x4 cube, and you will shortly master the ability to create center blocks intuitively.
The 2nd center block: The second center block to solve needs to be the opposite in color to the previous we've just solved: Since we'd just solve the yellow center block, now we should solve the white center block This applies only to original color scheme cubes! Where yellow is in opposite to white, red to orange, and blue to green.
Flip the cube upside down, so the yellow center block will be on bottom. The way to solve the white center block is by repositioning the white center pieces, one by one or in pairs , into the top face without harming the solved center block on bottom of course. Therefore, we make an r' move and take down the non-white center pieces on top into the F face, then switch them with the 2 white pieces, by doing F2.
There are 2 yellow pieces on the back face at the moment, which will go back into their solved position in the next move.
Now we'll finally reverse the r' move by doing an r move. The white pieces are now correctly positioned on the top face, and all yellow pieces on the bottom remained unharmed. This is an important idea in understanding the 4x4 solution.

It's just like an "elevator" move, we bring down the "elevator" toward the pieces we want to reposition, "upload" the pieces into the "elevator", and elevating them upwards into the solved position.
That way we are able to position pieces while preserving already solved pieces. When 3 center pieces are on top: Same idea is implemented here: We'll use the elevator idea as well.
In fact the algorithm is almost similar- Solution: [ r' F r ] The only difference is that we have to make only single F turn, because one white piece was already "inside" the elevator. The 3rd center block: we can choose any of the remaining four colors to be the third block to solve.
In this guide I chose red. Solution: [ U' r U ] Explanation: we'll make a U' move so when we'll make the r move, the two red pieces will become adjacent to each other, and not diagonal , then we'll make the r move to pair-up the 2 red center pieces, and finally we'll make a U move to align them both on the left. In the following example, both of the remaining pieces are on the right side internal right of the cube one is on the top face : Solution: [ F2 r' F r ] Explanation: First we'll make an F2 move to reposition one piece into the left side so the next r' move will not affect it, and it will pair up with the piece currently on top The reason we make F2, and not F', is because that in the next move we want them to pair-up adjacently to each other, and not diagonally.
Then we'll make the r' move to pair-up the pieces. Now we'll make an F move to align both pieces on the right side of front face. Finally we'll make an r move to solve them into their final position on the top face, so all 4 red center pieces are completely solved. The 4th center block: The fourth center block to solve is the opposite in color to the one we've just solved, meaning the orange again, applies only to original color-scheme cubes, where the orange is opposite to red. We'll have to bring all the orange center pieces into the top layer.
Hopefully some of them are already there. We'll use the "elevator" principle to upload the orange pieces into the top, without harming the red pieces on the bottom.
Here is an example to how it's done: Solution: [ r' F' r U ] Explanation: first we'll make the r' move, to take down the "elevator" with the non-orange center pieces on top. Then we'll make an F' move to upload the piece into the elevator Doing F', and not F2, is just right, in order to match-up adjacently with the orange piece on top. Next we'll make the r move to elevate the elevator back up into the solved position. Finally we'll make a U move to align both pieces on the left side of the center in order to "free" the elevator for the next 2 pieces.
Solving the remaining 2 center pieces: the best way to solve the remaining 2 pieces is by repositioning 1 piece at a time into the top layer, using the elevator principle: Solution: [ r' F r ] If you forgot, we cannot just make an [r] move, because there are red center pieces to preserve on the bottom Explanation: we'll make an r' move taking down the "elevator" , then we'll make an F move to upload the orange piece into it, finally we'll make an r move to upload the orange center piece into the solved position.
Now we'll apply again the exact same idea for the last center piece: Solution: [ F2 r' F r ] Explanation: First we'll make an F2 move to position the orange piece on the left internal side on the cube We make F2, and not F, because we want it to adjacently match the other orange piece that will go down the next more. Then we'll make an r' move taking down the elevator , then an F move to upload both pieces into the "elevator".
Finally we'll upload both pieces with an r move, and solve the entire orange center block.
These centers can be solved correctly, and incorrectly. Let's choose the green color to find out its correct position out of the 2 available places to be.
According to the original color scheme, when the yellow color is on top, and the red color is on the front face- the green should be on the right. Flip the cube so the green-to-be face will be on top.
Here is how to do it: Position a green center piece on the left side, using some U moves. Make an r2 move, and see whether 2 adjacent green pieces formed on the top face.
If after doing the first r2 move you have no adjacent green colors, reverse the r2 move, and make some D moves look at the bottom face to see how many needed , so when you'll make another r2 move again, a green piece will be repositioned into the top and will match-up with the green piece which is already there. Example: Bottom face looks like: x rotation Solution: [ D' r2 U' r2 ] In this case, there is no existing green pair on top already Look only at the left image for notations.
Then an r2 move to match-up 2 green pieces together elevator comes upwards , then a U' move to align both green pieces on the left side "unloading" from the elevator. Finally an r2 move to reverse all the other pieces back to place elevator goes back down. If one piece is on top: the easier case. Make an r2 move and match-up the 2 green center pieces.
Finally make an r2 move to upload both pieces into the top. All green pieces are solved now, and all blue pieces are on the bottom All center pieces are solved!

Explanation: make an r2 move so one green piece will go upwards into the top layer. Now make an r2 move to bring the green piece back down. The green center pieces are now adjacently to each other- Continue according to the adjacent case instructions below.
Adjacent: [ r2 D2 r2 ]. You had solved all 6 center blocks correctly to each other. I recommend you to stop here and practice on solving all center blocks of the 4x4 cube till you feel comfortable in doing so intuitively. It shouldn't be too hard for an experienced 3x3 Rubik's cube solver to do so in a day or two. Step 2- Pairing-up all edge pieces The second step is about pairing-up all the edge pieces with their identical twins on the 4x4 cube, into edge blocks.
There are 12 edge-blocks to solve, meaning 24 edge pieces in total. At the image to the right you can see an example of 2 white-blue edge pieces matched-up together into one edge block a white-blue edge block The edge blocks permutations around the cube are completely meaningless at this step.
We'll start with the 4 on top. Here is how it's done: Look for 2 identical edge pieces that are positioned like in the image, then execute the next algorithm: Algorithm: [ d R U R' d' ] This algorithm is pairing-up the two edge pieces into a block and storing them on the top face, without harming any center piece.
Here's how: by doing a d move, the 2 edge-pieces will pair-up. Then using the R move the formed edge-block will move upwards into the top layer. If there are already solved blocks- we want to make sure not to take them down instead. Finally we'll make R' d' to bring back all other pieces into place. How to bring the edge pieces into the case above? Here is a quick algorithm to move 2 edges into the desired position see image : Solution: [ L' U L ] Using this simple algorithm you'll be able to correctly position 2 edge pieces that are on the same face and has the same color on the mutual face if not, just make a U' move into the desired case.
Then just perform the corresponding algorithm [ d R U R' d' ] , and both pieces will pair-up and store on the top face.
Using the method above you'll be able to bring all 8 first edge pairs into the simple case position. Start with the easier edges that are already in this position.
The less edge pieces will remain, the easier it will get. For paired-up edges on the bottom just make a double move of its side face to bring it into the top face.The aim is to perform the moves continuously and to have a good transition between each step.
You might notice the cube looks like a regular 3x3 Rubik's cube, and that's how you are going to solve it now, as explained in the next step instructions.
For this step, you'll be filling in the white corners of the white cross. Lower-case letters mean turning 2 layers of the corresponding face.
Solving the White Cross We teach you the first step — creating a white cross on the white face of the cube. During pre-inspection, take more than 15 seconds.
