A simple solution to a Rubik's cube is the algorithm R' D' R F' D' R R’ D D R D R’ D’ R F R U R’ U’ F’ R U R’ U R U U R’ U U R U’ L’ U R’ U’ L R’ D’ R D. The algorithm uses the key: F for front, R for right, U for up, B for back, L for left and D for down. Apostrophes mark counter-clockwise rotations.
The simplest solution to a Rubik's cube begins creating a white cross on one side of the cube, keeping the center pieces on any side the same color. Next, turn the edges so the side with the white cross is completely white using the algorithm R' D' R F' D' R R’ D D R D R’ D’ R. Then, using the F2L Right and Left algorithms, complete the second layer by making one side completely gray.
Step four is making a yellow cross on the gray side using the algorithm F R U R’ U’ F’. Use the algorithm twice if the step begins with a yellow L, but use it once if the step begins with a yellow horizontal line. Next, make the edges yellow with the algorithm R U R’ U R U U R’ U.
Then, move the last layer's yellow corner pieces into place with the algorithm U R U’ L’ U R’ U’ L. If necessary, perform the algorithm more than once to move the pieces into place. The last step is moving the final colors into place with R’ D’ R D two times through.
