Color-code the digital 2D net map to match your physical cube.
Solve the four white mega-edges around the white center.
One critical concept for big cubes is "parity." This is a special error state that can occur, which has no analog on a 3x3 cube. It's when the puzzle is nearly solved, but two pieces (usually edges) are in an impossible position relative to each other. On a 7x7, you may encounter parity on the last two edges, often identifiable by a single flipped edge piece. Solving this requires a specific algorithm (like (R*2 B2 U2) (L* U2 R'* U2) (R* U2 F2 R*) (F2 L'* B2) R*2 ) to fix the state. This algorithm must be applied carefully to only the incorrectly flipped pieces.
The process was delicate. Leo had to map the cube into the software. He painstakingly scanned each face—Center White, Center Yellow, Blue, Green, Red, Orange.
Once centers and edges are paired, solve the rest as you would a 3x3.
Look at the white face. Form a vertical or horizontal line of five white center pieces in an outer layer, then slide it into the center grid.
inner grids on all six sides so each side shows one solid color.
The final two edges are the hardest because you run out of "safe" spaces to store completed edges. You must use specialized algorithms to swap and flip the remaining pieces simultaneously. Phase 3: Solve it Like a 3x3
Heuristic: center solving never exceeds 150 moves.
After white is done, turn cube so white is on D. Solve yellow on U.
The solve continued.
