Sudoku

Sudoku is a logic-based puzzle played on a 9x9 grid divided into nine smaller 3x3 boxes. The goal is to fill the grid with numbers from 1 to 9 so that each row, column, and box contains each number exactly once. Some cells start with given numbers, which serve as clues. The challenge is to use logical reasoning to deduce the correct placements without guessing. Sudoku develops deductive skills and pattern recognition, offering a satisfying mental exercise that balances structure and problem-solving within a defined, consistent framework.
