How to Solve a Mirror Cube
Solve a Mirror Cube with the 3×3 method by reading piece height and shape instead of sticker colors.
Work in order
The route to a solved puzzle
At every step, replace “which color belongs here?” with “which piece creates a flat surface here?”
Complete the first layer
Insert the four corners so every side of the layer forms a continuous, flat surface.
Algorithm
R U R′ U′Solve the middle layer
Match each edge by length and thickness, then insert it right or left as on a 3×3.

Use the familiar 3×3 sequences for the cross and corner orientation, following height rather than color.

Place the remaining corners and edges until all six faces are flat and the cube returns to its original shape.
