Learn the infamous third layer of the Rubik's Cube—the easy way!

FAQ:

"The last algorithm doesn't work!"

Yes it does. You need to pay closer attention. One of three things is probably happening: (1) You forgot the final "bottom layer to the right" move. Remember: when the corner's yellow sticker appears on the top, you're not done! You still have to finish the algorithm by turning the bottom layer to the right. (2) You forgot to turn ONLY the top layer after solving a corner. Turning the whole cube after you solve a corner is INCORRECT. Repeat the full algorithm until yellow appears on top, and then turn ONLY the top layer to the next corner, exactly as I explain at 5:27. (3) You have a corner twist that you caused earlier. This makes the cube impossible to solve with regular turns. Just take any corner on the cube, twist it clockwise, and try to solve the cube again. If it still doesn't work, take any corner on the cube, twist it clockwise, and try to solve it again. It will work this time if you do it correctly. If you want to be able to tell if it's solvable or not, scroll down to the bottom of the description.

"What do I do if no corners are in the right place?"

Do the dodge on any corner. I explain this at 4:28.

"How can I trust you since the video had a jump cut at 4:55?"

Because the video is correct and the jump cut doesn't skip any information that I haven't already gone over.

"I skipped completely past this step in the video, what do I do?"

Keep watching the video until I get to the part where you are at.

"I still need help!"

Watch my example solves. If that still doesn't work, please ask a specific question using a time stamp, and I will gladly help you until your problem is completely solved.

"Why are you teaching such a slow method?"

This is tutorial is for beginners. I also have tutorials for more advanced cubers.

"Why am I even here, I already know how to solve?"

Ok.

"Why do you keep saying wrong move names?"

Sorry. In this video I name the moves directionally as opposed to traditionally. In retrospect I should have gone with traditional notation (which I explain in my Solve the Third Layer Faster video). I've added traditional notation for this video below:

0:50 - Face: F (R U R' U') F'
3:00 - Push: R U R' U R U2 R' U
3:56 - Dodge: U R U' L' U R' U' L
5:25 - Twister: R' D' R D

The FACE gets you the yellow cross.
The PUSH gets you the vertical bars.
The DODGE puts the yellow corners in the correct places.
The TWISTER twists the yellow corners until they are solved.

F Front face clockwise
U Up (top) face clockwise
R Right face clockwise
L Left face clockwise
D Down (bottom) face clockwise

' Actually, turn that face counterclockwise
2 Actually turn it twice (in either direction)

HOW TO TELL IF A CUBE IS SOLVABLE (or if you have a corner twist)

Get to the spot where all you have left is the twister algorithm.
Grab paper and a pencil and examine each of your four corners:

•If it is solved (yellow on top), write a 0 on the piece of paper.
•If it is rotated clockwise (yellow on the right side), write a 1.
•If it is rotated counterclockwise (yellow on left), write a –1.

You should have FOUR different numbers on that paper, one for each corner. Add them all together!

•If your total is 0, 3 or –3, your cube is solvable!
•If your total is 1 or –2, take one of the yellow corners and twist it counterclockwise, and your cube will be solvable!
•If your total is –1 or 2, twist one corner clockwise.

There you have it!
