If you feel that youve already mastered the beginner method and are itching to get faster, heres a logical next step. If youre using my beginner method, it takes you one look to orient edges, up to three looks to orient corners, up to two looks to permute edges, and up to three looks to permute corners. The last layer can be really challenging not to mention long if you only have one or two algorithms to stick with through the entire process. There are 21 different variations of last layer permutations, and a wellknown name for each. Despite the low design aesthetics, the app proved to offer powerful capabilities in our i would recommend that you keep using the 2 look algorithms until you feel confident with most of this speedcubing guide. There will be a separate document for 2 look pll or 4 look last layer 4lll, which is going to be a subset of these algorithms. You then only have to learn 6 of them at the expense of speed obviously.
