  • Are you looking for a creative way to impress your friends with your skills? Here's an idea:

  • I'm going to show you the way to solve a 2x2 Rubik's Cube that works 100% of the time!

  • First things firstlet's study the Rubik’s Cube lingo. It's all simple and logical.

  • R – turn the right face of the cube clockwise 90 degrees

  • R' (apostrophe) – turn the right face counter clockwise 90 degrees

  • L – left face clockwise L' (apostrophe) – left face counter clockwise,

  • U – upper face clockwise, U' (apostrophe) – upper face counter clockwise,

  • F – turn the front face clockwise, F' (apostrophe) – turn the front face counter

  • clockwise, D – down face goes clockwise

  • D' (apostrophe) – down face goes (you got it) counter clockwise

  • B – back face clockwise B' (apostrophe) – back face counter clockwise

  • So, as you can see, each capital letter stands for a face of the cube that turns clockwise.

  • When there is an apostrophe, it means you should go counter clockwise 90 degrees.

  • We're going to use 8 basic moves to solve a 2x2 cube. The cube will rotate clockwise

  • if you look at it from the right face side that's marked with an X. We'll only use 3

  • algorithms, so it's all really simple, like I promised. Trust me.

  • 1. The right fingertrick

  • It just takes 4 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 counter clockwise, and upper face counter clockwise.

  • Easy, right? Let's see how it works on a real cube.

  • Turn the right face of the cube clockwise, upper face clockwise, now, right face goes

  • counter clockwise, and upper face counter clockwise.

  • Let's do it again: right clockwise, upper clockwise, right counter clockwise, and upper

  • counter clockwise. Once again: right, upper, right, upper, and

  • the fourth time. I think I mastered it!

  • 2. The left fingertrick

  • This is a mirror reflection of the previous algorithm and it's also done in 4 moves. The

  • left face goes counter clockwise, the upper face goes counter clockwise. Then, the left

  • face turns counter clockwise, and the upper facecounter clockwise.

  • That's the algorithm, let's see how it works on a real cube.

  • So you turn the left face counter clockwise, the upper face counter clockwise, the left

  • face counter clockwise, and then the upper face counter clockwise again.

  • And, once again: left, upper, left, upper. Keep going.

  • One more time: left counter clockwise, upper counter clockwise, left counter clockwise,

  • upper counter clockwise.

  • 3. Corner rotation

  • Just like the previous two algorithms, this one is done in 4 moves.

  • First, you turn the right face clockwise, then the front face counter clockwise. Then,

  • right face goes counter clockwise, 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, counter clockwise, counter clockwise, clockwise.

  • And one final move. There you go!

  • Now it's time to solve that cube. What shall we begin with?

  • It takes 3 stages: 1. First, we'll solve the bottom layer

  • 2. Then, we'll solve the top layer 3. Finally, we'll swap the corners.

  • 1. 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 fingertrick 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.

  • 2. 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.

  • 1. If two corners are next to each other.

  • Take the cube in your left hand holding the two matching corners and do the right fingertrick

  • three times. Do you remember how to do it? It's right face clockwise, upper face clockwise,

  • the right face counter clockwise, and upper face counter clockwise. Once again. There

  • you go. One more time.

  • Now turn the entire cube clockwise and do the left fingertrick three times. Left face

  • goes counter clockwise, upper counter clockwise, left counter clockwise, upper counter clockwise.

  • Once again. And the final move.

  • In case you've done it right, all the corners will be in place.

  • 2. 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' U' three times,

  • turn the cube clockwise and do the L' U' L U moves 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.

  • 3. 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 a 2x2 Rubik's Cube with just three algorithms!

  • So, did you solve it no problem? Let me know in the comments below!

  • Ready to move on to a larger cube?

  • A 3x3 Rubik's Cube has the same lingo as the 2x2. There will be 8 basic moves, 6 algorithms,

  • and seven stages.

  • #1. White cross #2. White corners

  • #3. The middle layer #4. The yellow cross

  • #5. The yellow edges #6. The yellow corners

  • #7. The final stage

  • #1. White cross

  • There are no algorithms solving the white cross. You just have to go with your intuition

  • and rotate the side layers to get there. This is the very first and the easiest stage of

  • solving the cube. You can check if the edges are in the correct position using the central

  • elements of the cube. Try to keep the cube white side down, it will make things easier

  • in the next stages.

  • #2. White corners

  • You can put the corners of a 3x3 cube into place using the same algorithms as for the

  • 2x2 one.

  • If the white part of the corner is facing right, use the first fingertrick.

  • If it's facing you, then go with the second one.

  • If the white part is facing up, try using any of the algorithms until it's in the right

  • place.

  • Let's try it on a real cube.

  • Take the corner that you want to put in the right place and move it so it's above the

  • desired position. To check it, you can rotate the right or frontal face so that the corner

  • falls into place, then put it back up and use one of the algorithms depending on where

  • the white part is.

  • #3. The middle layer

  • You are going to need two algorithms to solve this one. The right and the left center rotation.

  • Because you are a pro with all the algorithms already, this should be no big deal.

  • Let's see how it works.

  • The task is to put the four edges of the middle layer in the right place. Let's find the element

  • that must be moved to the middle layer and align the colors with the center of the middle

  • layer. Use the right or the left algorithm depending on the situation. If the edge you

  • need is in the middle layer but not in its place, just use any of the algorithms to knock

  • it out of there.

  • #4. The yellow cross

  • For the yellow cross, you are only going to need one algorithm. If it doesn't work out

  • the first time, keep trying until you get the yellow cross.

  • There you go. Let's see how it works.

  • Front face clockwise, right face clockwise, upper face clockwise, right face counter clockwise,

  • upper face counter clockwise, and front face clockwise.

  • #5. The yellow edges

  • Here's an algorithm that shifts the two central edges of the upper layer that are in a diagonal

  • line. There is a number two next to U in the algorithm here. It means you should turn it

  • twice. It might look confusing but it's easier done than said. How often does that happen?

  • Let's align the central edges of the top layer with the cube's centers, at least two colors

  • have to match. If the two colors are next to each other, only use the algorithm once.

  • If they are opposite each other, use the algorithm twice.

  • If four colors are matchingcongrats! You can skip this stage.

  • #6. The yellow corners

  • If you're getting tired, no worries, you're almost there! To put the corners in the right

  • places, we're going to use the corner swapping algorithms that moves three corners clockwise.

  • Enough said, let me show you how it works.

  • Right face counter clockwise, front face counter clockwise, left face counter clockwise, front

  • face clockwise, right face clockwise, front face counter clockwise, left face clockwise,

  • front face clockwise.

  • Using this algorithm, you can get the corners in the right positions in any situation. Keep

  • going as many times as you have to until you make it.

  • #7. Final stage

  • Are you still there? We're at the finish line. Now you have to swap corners yellow side up

  • just like in a 2x2 cube.

  • The algorithm is simple. Youve gotta keep going until the yellow part is on top. Without

  • changing the cube's position, turn the upper layer moving the next corner you want to get

  • in place. Eventually, it will all be done.

  • Let's try it on a real cube.

  • Right face clockwise, front face counter clockwise, right face counter clockwise, front face clockwise.

  • If it seems like you're only making it worse, no worries. It's just an illusion. Kinda like

  • me. Mu-wha-ha-ha!! Keep using the algorithm until it works!

  • Once again. And again.

  • And congratulations! You've made it!
