Sudoku

Sudoku game is one of the all-time most-played puzzle games. This logic-based number puzzle requires players to fill a 9x9 grid with numbers so that each row, column, and 3x3 square contains all digits from 1 to 9. The game is simple in concept but can range from easy to extremely challenging, making it suitable for players of all skill levels.

Instructions

To complete a Sudoku puzzle, you need to fill the entire grid with numbers, ensuring that each row, column, and 3x3 sub-grid contains all the digits from 1 to 9 without repetition. The puzzle starts with some numbers already filled in, known as "givens." The difficulty of a Sudoku puzzle is determined by the number and placement of these givens.

1. Examine the Grid: Start by scanning the grid to see where numbers are already placed. Look for rows, columns, or 3x3 squares that are nearly complete and see where the remaining numbers can logically go.
2. Use Deduction: Using logic and process of elimination, determine where the remaining numbers can fit. Remember that each number can appear only once in each row, column, and 3x3 square.
3. Fill in the Blanks: As you deduce where numbers go, fill them in. Be careful and double-check your placements to avoid conflicts.
4. Solve the Puzzle: Continue using logic and deduction until the entire grid is filled correctly.
