Medium Sudoku requires cross-hatching and candidate pairing techniques. By analyzing row-column intersections, you will naturally develop structured problem-solving skills that help clear mental fatigue and build focus.
Look out for "Naked Pairs"—when two cells in a single row, column, or 3x3 block can only contain the same two candidate numbers. You can safely eliminate those two candidates from all other cells in that same group.
