For larger cubes (5x5 and up), speedcubers slice one layer open, match multiple edges in the open "slice," and restore the centers at the end. Phase 3: The 3x3 Phase & Parity
The Rubik's Cube is no longer limited to the classic 3x3x3 design. Today, cubers tackle massive NxNxN puzzles, ranging from the 4x4x4 (Rubik's Revenge) and 5x5x5 (Professor's Cube) all the way up to 21x21x21 and beyond. xnxnxnxn cube algorithms pdf nxnxn rubik cube link

Because there are so many pieces, hunting for a single missing center piece slows you down. Practice looking for the next piece while solving the current one.
Happy solving, and may your parities be few and your solves be swift.
This occurs when an edge group appears flipped upside down during the
