Sudoku is a logic-based number puzzle played on a 9×9 grid, divided into nine 3×3 subgrids. The objective is to fill the entire grid with numbers from 1 to 9, ensuring that each row, each column, and each 3×3 subgrid contains every number exactly once. Some numbers are pre-filled to give players a starting point. The challenge lies in using logic to figure out where the remaining numbers belong, without repeating any number in a row, column, or subgrid. No math is involved, just pure logic and pattern recognition!
