The Sudoku dataset comprises 300 puzzles in total: 100 instances for the standard 9×9 size, 100 for 16×16, and 100 for 25×25. Each puzzle was deliberately selected based on documented extreme difficulty, minimal-clue characteristics, and recognized computational hardness, rather than random generation, to ensure meaningful stress-testing conditions.
