Choose a method (beginner: layer-by-layer; faster: CFOP)
Gather the cube, confirm orientation, and define a consistent color scheme (pick one color as Up and one as Front)
Make the white cross on the Down layer
Solve the white corners to complete the first layer (Down face fully solved)
Solve the second layer edges (middle layer)
Make the yellow cross on the Up face
Position yellow corners to make the correct top-layer corner arrangement (yellow cross to full yellow face)
Orient the yellow corners (make the Up face all yellow)
Permute the last-layer edges (swap top edges to correct positions)
Permute the last-layer corners (swap top corners to correct positions)
Verify the cube is solved (all faces uniform)
