Detailed Answer
Sudoku is a number puzzle on a 9x9 grid divided into nine 3x3 boxes. Some cells are pre-filled with numbers. Your goal is to fill every empty cell so that each row, column, and 3x3 box contains the numbers 1 through 9 exactly once. Start by looking for cells where only one number is possible. Use the process of elimination and cross-reference rows, columns, and boxes.
