How to Play Sudoku
Sudoku is a number puzzle played on a 9x9 grid. The grid is divided into nine 3x3 boxes. The objective is to fill the grid with digits from 1 to 9, ensuring that each column, each row, and each 3x3 box contains all digits from 1 to 9 exactly once. No repetition is allowed.
Tips for Solving Hard Puzzles
Hard puzzles require advanced techniques such as cross-hatching, pencil marks, and the use of pairs or triples. Start by scanning rows, columns, and boxes to identify numbers that can be placed with certainty. Use pencil marks to note possible candidates for empty cells, then eliminate possibilities as you fill in more numbers.
- Look for hidden singles: a number that appears only once in a row, column, or box.
- Use the X-Wing technique: when a number appears in two rows and two columns, it can eliminate possibilities in other cells.
- Try the Swordfish strategy: an extension of X-Wing involving three rows and three columns.
Remember, patience is key. Hard puzzles may take 20 to 30 minutes or more. Avoid guessing; every move should be based on logic.
