Here it is! The simplest, most comprehensive, interactive solution tutorial to the last layer of the 3x3 Rubik's Cube!
Even though the video is over 20 minutes long, you'll be clicking around a lot to get to different parts, so don't be put off by the video's length. Also, this tutorial is very slow and comprehensible, so unlike my last video, you won't have to pause and rewind so many times.
If you don't feel like following the video, here are the actual typed formulas for the third layer:
1. Making the cross: F R U R' U' F'
(Dot [in any orientation], then L shape [with tips pointing down and to the right], and then the [horizontal] line)
2. Aligning the cross: R U2 R' U' R U' R'
(One correct piece facing you and one facing away, then one incorrect facing you and one to the right)
3. Placing corners: L' U R U' L U R' U'
(Any orientation if all corners false. Otherwise, correct corner on bottom right)
4. Final Step: R U2 R' U' R U' R' L' U2 L U L' U L
(Keep false corners on bottom right and, if possible, top right)
Happy Solving!
