Rubik's Cube

Basics, terminology

Goal

Orientation

Permutation

vs

• Centers are fixed

• There's only one solution to the cube

• We place edges and corners into their correct positions with correct orietnation

Layer by Layer (LBL)

What we are going to learn

Cross

4 edges

1st layer

4 corners

2nd layer

4 edges

Edges orientation

4 edges

Corners orientation

4 corners

Corners permutation

4 corners

Edges permutation

4 edges

Cross

• Four edges that are in correct permutation and orientation on the same face
• No algs, 100% intuition
• Recommended to always do the same color
• Recommended to keep the cross at the bottom
• Avg. 6-7 moves, max 8 moves

Corners of 1st layer

• One very easy, intuitive algorithm
• And some easy edge cases
• Recommended to keep the cross at the bottom
• Happy path: a setup move and four-moves alg is enough per each piece

Edges of 2nd layer

• One very easy alg with 8 moves
• 4 moves (reduction to previous case) + 4 already known moves
• A bit more complicated edge cases
• Happy path: a setup move + 8 moves per each edge
