: Once centers and edges are unified, solve the remaining puzzle using standard 3x3x3 algorithms .
Once you master the NxN system, a 7x7 feels exactly like a 3x3—just with a few extra steps.
Odd cubes (5×5, 7×7) can have solved by re-pairing a few edges – no special algorithm needed.
: Group all inner center pieces of the same color on each face.
The "X" acts as a mathematical variable (often written as N ). So, an cube is any cube of order N .
