Step By Step Instructions To Solve a 3×3 Rubik’s Cube

So what's on the inside of this mysterious construction and how does it even work well stay tuned take a rubik's cube and move the top face so it's not lined up once it's done you can carefully pull one of the edge pieces up with your fingers you can even go further and make several other pieces fall off as you can see the core holds .

Six center pieces one for each side even though they do rotate none of them can change their position since they're fixed in place which means that in the original cube with standard colors the red center piece will always be opposite from the orange one yellow across from white and the blue piece will be opposite from green .

The edge pieces have two colors each in the cube there are 12 such pieces forming across on each side and then there are eight corner pieces each of them has three colors the edges and corners aren't fixed to anything that's why they can move around the center parts pick up one of the pieces you've pulled .

Off and turn it around you can see some extra material on its inner part the cube keeps its shape because the edges and corners hold one another in place each piece has an internal tab that clings to the center cubes and the surrounding parts the tabs are shaped in such a way that they fit along a curved track formed by the backs of other .

Pieces that's how the cube moves if you look at the process from the inside and now time for the most exciting part solving the rubik's cube okay thanks qb you can get dressed looks like the exam's over now first of all you'll need to learn the rubik's cube lingo it's both simple and logical boy if only the rest of my .

Life were that way all moves are written down in letters that stand for one 90 degree cube rotation u up d down l left r right f front b back there's an optional h hurl and s smash just in case you get frustrated hey i'm only kidding if you see an apostrophe next to the letter it means the layer should move .

Counterclockwise by 90 degrees no apostrophe the layer goes 90 degrees clockwise a number next to the letter means the number of turns you should make and here's the main algorithm for your right hand it'll be r u our apostrophe u apostrophe once again r .

U r apostrophe u apostrophe it's the exact opposite for your left hand l apostrophe u apostrophe l u repeating that's l apostrophe u apostrophe l u now if you want to nail it on the first attempt it's a great idea to practice sooner or later you'll be able to do all .

The moves nearly automatically it'll help you later on oh and by the way if you repeat these moves six times the cube will look exactly like it did at the very beginning to solve the puzzle you'll have to go through seven stages white cross white corners .

The middle layer the yellow cross the yellow edges the yellow corners the final stage here we go white cross the task here is to put together a white cross and then align its edges with the right colored center .

On each side to begin with you have to put together a sequence that resembles a daisy it's quite easy and doesn't need any special algorithms then rotate the top layer with the daisy your goal is to make the front tile of the top edge piece match the color of the center piece .

And rotate this layer 180 degrees do the same thing with the remaining whites and this is how you get a white cross at the bottom white corners at this stage you'll have to put the lower corners of the cube in the right places and the cube's white side will be solved ready you have to use that r u r .

Apostrophe u apostrophe algorithm for your right hand rotate only the top layer of the cube to find a corner that has the same color as the centers of the other sides then use the algorithm until the corner is in the right place do the same with the other corners at this stage you'll have to concentrate .

On the rest of the middle layer your task is to make the edge pieces the same color as the center in the first case the layer you'll be working on is to the left on the top of the target position you must match it with the right color here's how you can do it turn the upper part to the left .

Use the algorithm for the right hand rotate the cube left use the algorithm for the left hand in the second case the layer you'll be working on is to the right of the top of the target position turn the upper part to the right use the algorithm for the left hand rotate the cube right .

Use the algorithm for the right hand repeat that with all the sides and you're done now the yellow cross for the yellow cross you are only going to need one algorithm so front face clockwise right face clockwise upper face clockwise .

Right face counterclockwise upper face counterclockwise and front face counterclockwise got that if it doesn't work out the first time keep trying until you succeed okay now you're ready for your first algorithm it consists of seven steps number one build a white cross on the bottom .

Number two solve the white corners number three solve the middle layer number four build a yellow cross number five swap yellow edges in the top layer number six get the yellow corners in the right position number seven solve the final layer corners .

Step one build a white cross on the bottom hold the cube with the white face up in this case the white face is the one that has a white center there's no strict algorithm for this step so try building the white cross following your intuition first you should get something looking like a daisy when you're done with it .

Align the right colors of the layers with the color of the center and rotate this layer 180 degrees do the same thing with the remaining whites and this is how you get a white cross at the bottom step 2 solve the white corners the goal of this step is to have three cubes of the same color in the top layer .

And one cube in the center of the middle layer of the left right front and back faces the white side of the cube will be solved you'll need to use the main right hand algorithm for this step twice rotate only the top layer of the cube to .

Find a corner that's the same color as the centers of the other sides first the right face goes clockwise then shift the up face clockwise the right face goes counterclockwise finish the algorithm by rotating the up face counterclockwise in case the corner is placed correctly in the bottom layer but not oriented .

Correctly repeat the algorithm until the corner is in the right place do the same thing with the rest of the corners step 3 solve the middle layer at this stage you'll need to solve the rest of the middle layer so that the outer blocks are the same color as the center rotate the cube to move the .

Completed white face to the bottom no worries you can't mess it up everything will fall back into position if you follow the algorithms there are two possible scenarios for this layer if you need the center top piece to move to the second layer left here's an algorithm for that let's go through it rotate the up face .

Counterclockwise the left face goes counterclockwise rotate the up face clockwise move the left face clockwise the up face goes clockwise the front face goes clockwise the up face goes counterclockwise and the front face goes counterclockwise if you need the center top piece to go .

To the second layer right use a different algorithm so for this one start with rotating the up face clockwise then shift the right face clockwise the up face goes counterclockwise rotate the right face counterclockwise and the up face counterclockwise the front face goes counterclockwise and .

The up face goes clockwise finish this step with shifting the front face clockwise repeat that with all the sides and you're done step 4 build a yellow cross the goal of this step is the same as with the white cross but there are more things to think about here here's the .

Algorithm for this step rotate the front face clockwise the right face goes clockwise now rotate the up face clockwise and the right face counterclockwise the up face goes counterclockwise finally rotate the front face counterclockwise at this point you might see one of the .

Three different patterns on your cube depending on which one it is you should run the algorithm for this step a certain number of times if you have a single yellow dot on your cube perform the algorithm three times if it's an l shape start with rotating the cube so that the legs of the l shape encase the edge pieces in the top left .

Run the algorithm twice if you have a line rotate the cube until the line is horizontal then go through the algorithm just once step 5 swap yellow edges in the top layer now you need to arrange the edges of the yellow cross so that the second color .

Coincides with the color of that side find one edge that's already in place rotate the top layer of the cube to align the edge with the corresponding color it's important that only one edge is matching keep it in front of you and use the algorithm until the remaining edges get in the right positions let's give it a .

Go start by rotating the right face clockwise next turn the up face clockwise and the right face counterclockwise now rotate the up face clockwise the right face goes clockwise as well now the up face goes counterclockwise two times .

Turn the right face counterclockwise to finish the algorithm step six get the yellow corners in the right position at this stage the task is to get the remaining yellow corners where they belong you only need to move them in place you're not solving them just yet find the corner that's already in place .

In this case it's even rotated correctly but that's not important and use this algorithm until the corners are in their places okay let's do it turn the up face clockwise the right face goes clockwise as well rotate the up face counterclockwise and the left face counterclockwise the up face goes clockwise and the right face .

Counterclockwise now turn the up face counterclockwise and the left face clockwise keep going until you make it step 7 solve the final layer corners you're almost done all you have to do is solve the corners rotate the cube so that the yellow side is facing you you'll work with the upper right corner let's solve it corner by .

Corner using this algorithm turn the up face clockwise and the right face counterclockwise rotate the up face counterclockwise the right face goes clockwise once you're done with one corner move to the next one by rotating the side that's facing you keep using the same algorithm .

Rotate the front layer so that all colors of the cube match congrats you now know how to solve a 3×3 rubik's cube if you want to do it faster get a high quality cube probably a speed one learn the basic algorithms by heart and give it as much .

Time and practice as you can then the moves will come automatically and you'll be able to solve the cube in under five seconds no problem i'm going to show you the way to solve a two by two rubik's cube that works one hundred percent of the time one the right finger trick it just takes four moves and helps us .

Solve most of the cube turn the right face of the cube clockwise 90 degrees upper face clockwise the right face counterclockwise and upper face counterclockwise easy right let's see how it looks on a real cube turn the right face of the cube .

Clockwise upper face clockwise now right face goes counterclockwise and upper face counterclockwise let's do it again right clockwise upper clockwise right counterclockwise and upper counterclockwise once again right upper right upper and the fourth time i think i mastered it .

Number two the left finger trick this is a mirror reflection of the previous algorithm and it's also done in four moves the left face goes counterclockwise upper face counterclockwise left face clockwise upper face clockwise that's the algorithm let's see how it works on a real cube .

So you turn the left face counterclockwise upper face counterclockwise left face clockwise and then upper face clockwise and once again left upper left upper keep going one more time left counterclockwise .

Upper face counterclockwise left face clockwise upper face clockwise number three corner rotation just like the previous two algorithms this one is done in four moves first you turn the right face clockwise and then the front face counterclockwise then right face goes counterclockwise and finally the front face turns .

Clockwise let's try it right front right front one more time right front right front and again clockwise counterclockwise counterclockwise clockwise and one final move .

There you go now it's time to solve that cue what shall we begin with it takes three stages one first we'll solve the bottom layer two then we'll solve the top layer three finally we'll swap the corners one solving the bottom layer first let's find the right corner it's .

Usually marked with a sticker and is white blue and red we'll start with it let's see which corner it will be easiest to put next to it is it going to be blue and white or red and white i see it's red and white let's put it where it belongs and use the first finger trick on it until it's in the right place with white facing .

Down okay let's do the same with the remaining white corners trust me the more you practice the easier it gets one more time done the bottom layer is solved two solving the top layer let's find the corner that matches in .

Two colors with the bottom layer that's already solved and put it in the right place once you find the first corner you have to keep looking for the second one without relocating the first corner here two cases are possible the two corners can be next to each other or .

Placed diagonally one if two corners are next to each other take the cube in your left hand holding the two matching corners and do the right finger trick three times do you remember how to do it it's right face clockwise upper face clockwise the right face counterclockwise and upper face .

Counterclockwise once again there you go one more time now turn the entire cube clockwise and do the left finger trick three times left face goes counterclockwise upper face counterclockwise left counterclockwise upper face .

Clockwise once again and the final move in case you've done it right all the corners will be in place two if two corners are in a diagonal in this case it doesn't matter how you hold the cube but the white side has to face down .

Now let's do the same as for neighboring corners so it's the r u r apostrophe u apostrophe three times turn the cube clockwise and do the l apostrophe u apostrophe l u be moved three times now let's find the corners that are next to each other and we have the same setting as in the first case .

three swapping the corners now all you have to do is swap all the corners yellow side up grab the cube white side down and let's keep swapping the corners until the yellow part of the rotating corner is up without rotating the cube itself keep turning the upper side towards the .

Corner that's not in place and keep using the algorithm it might seem like you're messing it up but no worries once you finish with the last corner yellow side up it will be all done congrats you've successfully solved the two by two rubik's cube with just three algorithms so did you solve it no problem let me know in the comments .

Below well today i have a special treat for you you'll learn the fastest possible way to solve a skewb just like with the rubik's cube it only takes one simple algorithm although it looks a lot like a rubik's cube it's actually a type of pyraminx by the way if you want to learn to solve a .

Pair of mix let me know in the comments because of the peculiar way it rotates skew might seem like a really tough puzzle to crack but it isn't sound too good to be true alright i'm going to prove it to you let's start with skewb abc it consists of the parts of two types there are eight corners and six centers .

And now it's time to master the one and only key algorithm you'll need to solve a skewb step one rotate the skewb with your left hand clockwise step two right hand clockwise and then do the opposite step three left hand counterclockwise step four .

Right hand counterclockwise that's it now let's see how it works in real life left hand clockwise right hand clockwise left hand counterclockwise right hand counterclockwise i told you it would be easy once again left and right .

And left and right before you continue i recommend that you pause the video and practice till you can do it automatically let's try if you go through the algorithms six times the skewb will return to its original state we'll solve it in four steps first the white face and adjusting .

Corners second the yellow corners then the yellow center and finally the other centers okay let's give it a good shuffle and get down to work step one solve the white face .

Let your intuition guide you with this step it's really simple just try it what's really important here is to match the corners that are next to the white corners just like this .

it may seem hard at first so if you need help here you go case one if the corner you need to rotate is under your left hand make one turn with your right hand it's the most common scenario .

Case two if the corner you need is down and the white side is facing you you can deal with this situation in three steps first rotate the cube with your left hand then make one move with your right hand and move the left side back case three .

If the corner you need is on the bottom side of the skew it's a bit trickier but you can fix it in five moves first your right hand moves up then the left hand moves up after that you rotate once again with your right hand in the opposite direction then the left hand goes down .

The right hand goes up and you're done with the first step moving on to step two solve the yellow corners for starters let's position the skewb white side down and check where the yellow corners are there are two possible scenarios if your skewb looks like this you'll .

Just have to use the algorithm you've already mastered let's do it together hold this cube so that the two yellow corners on your right are facing different directions and the other two are facing left left right left .

Right voila if your skewb looks like this you have to use the same algorithm then rotate it 90 degrees and then apply the same algorithm once again i promise it's easier done than said so hold it like this and one two three .

Four now it's really important that you rotate it exactly 90 degrees go through the whole algorithm once again and one two three four and it's done .

The next step is step number three solve the yellow center so all the corners are solved now it's time to put together the yellow side again there are two possible scenarios in case the yellow side is already solved you can just skip step three and move on to step four if not use the algorithm you've .

Practiced rotate the skewb 180 degrees and then use the algorithm once again let's try it find the yellow center use the algorithm 1 two three four rotate it and once again .

Left right left right good job just one more step to go step number four solve the remaining centers just like in the previous step you have .

To find the right center apply the algorithm rotate the skewb and then use the algorithm once again let's try with the green side one two three four now turn it around and one two .

Three four done and now the same with the blue side one two three four turn around left right left right and that's it this cube has been successfully solved congrats .
