Expert Hyper Sudoku

Expert Hyper Sudoku — around 21 givens. The hardest Hyper tier we generate. Expert Classic at 25 givens is a comparable difficulty band; Expert Hyper at 21 stays balanced because the hyper regions contribute the constraint information the missing givens would have.

Expert puzzles lean on X-wings, coloring, and combined chain logic. Not a starting tier — but a natural step if you've been finishing Hard in ten minutes or less.
