Learn the absolute fewest moves required to clear a state.

Recent developments in AI (specifically DeepCubeA) have shown that neural networks can solve a 7x7 cube in fewer moves than traditional reduction methods—but not in real-time. Current AI solvers require massive computational power and take 30+ minutes to find a near-optimal solution.

If you need to solve a scrambled 7x7 right now, these are the most reliable tools.

Keep building 1x5 bars in the outer layers and slide them into the center until a complete 5x5 block of one color is formed.

Locate the fixed white center piece. Build 1x5 lines of white pieces in the outer layers and slide them into the center face. Because no other centers are solved yet, you do not have to worry about breaking anything.

With the centers grouped and edges paired, the 7x7 now behaves exactly like a massive 3x3 cube.
