How to solve a 3×3 cube in 7 steps
This is the summary. Open the app to watch each algorithm play live on the 3D cube.
Hold it right
First, hold the cube fixed: yellow center up, green center facing you. Centers never move, so a center sets its face’s color.
White cross
Make a white cross on the bottom, each white edge matching the center beside it.
White corners
Insert the four white corners to finish the bottom layer with R U R′ U′.
Middle layer
Place the four non-yellow edges into the middle layer.
Yellow cross
Make a yellow cross on top with F R U R′ U′ F′.
Match & position
Match the yellow edges, then position the yellow corners.
Orient corners
Twist the yellow corners up and the cube is solved.
Each step above has several small cases. In the app you tap a case to watch the 3D cube animate it.
