The Evolution of Sudoku: Over the years, Sudoku has evolved from a simple grid-based puzzle to a diverse range of variations and challenges. These variations include different grid sizes, such as 4x4, 5x5, and 9x9, as well as additional rules and constraints. Sudoku has also inspired numerous spin-offs, such as Killer Sudoku, Samurai Sudoku, and X-Wing Sudoku.
