1. Rubik’s Cube An introduction to cubing

2. Cube Composition • 6 Center cubies

3. Cube Composition • 12 Edge cubies

4. Cube Composition • 8 Corner cubies

5. Algorithm Notation • Turn 90 degrees clockwise • Front face: F • Back face: B • Left face: L • Right face: R • Upward face: U • Downward face: D

6. Algorithm Notation • Turn 90 degrees counter-clockwise • Front face: F′ • Back face: B′ • Left face: L′ • Right face: R′ • Upward face: U′ • Downward face: D′

7. Algorithm Notation • Turn 180 degrees • Front face: F2 = FF = F′F′ • Back face: B2 = BB = B′B′ • Left face: L2 = LL = L′L′ • Right face: R2 = RR = R′R′ • Upward face: U2 = UU = U′U′ • Downward face: D2 = DD = D′D′

8. The First Layer • Place the first layer edges

9. The First Layer • Place the first layer corners

10. The Second Layer • Place the second layer edges U′ F′ U F U R U′ R′ U R U′ R′ U′ F′ U F

11. Orient the Last Layer (OLL) • Orient the edges to make a cross • F U R U′ R′ F′

12. Orient the Last Layer (OLL) • Rotate the faces of 3 corners R U R′ U R U2 R′ R′ U′ R U′ R′ U2 R

13. Permute the Last Layer (PLL) • Rotate the positions of 3 corner cubies R′ F R′ B2 R F′ R′ B2 R2

14. Permute the Last Layer (PLL) • Swap the positions of 2 corner cubies • You need to go back to OLL after this algorithm L U′ R′ U L′ U′ R

15. Permute the Last Layer (PLL) • Rotate the positions of 3 edge cubies R2 U F B′ R2 F′ B U R2 R2 U′ F B′ R2 F′ B U′ R2
