Sudoku is a logic-based, number-placement puzzle. The goal of Sudoku is to fill a 9×9 grid with numbers so that each row, column and 3×3 section contain all of the digits between 1 and 9. At the beginning of the game, the 9×9 grid will have some of the squares filled in. Use logic to fill in the missing digits and complete the grid. Remember you must follow these rules: a row cannot contain more that one of the same number from 1 to 9, a column cannot contain more that one of the same number from 1 to 9, and any 3×3 grid cannot contain more than one of the same number from 1 to 9.
