What is Sudoku?
Sudoku is a logic-based number puzzle that has captivated millions worldwide. Played on a 9x9 grid divided into nine 3x3 boxes, the goal is simple: fill every row, column, and box with the numbers 1 through 9, with no repetition. Despite its simple rules, Sudoku offers endless challenges that sharpen your logical thinking and problem-solving skills.
