What is Sudoku and Why Should You Play It?




Sudoku is a logic-based puzzle that involves placing numbers from 1 to 9 into a 9x9 grid. The grid is divided into nine 3x3 subgrids, also called boxes or regions. The goal of sudoku is to fill in the grid so that each row, column, and box contains all the digits from 1 to 9 without repeating them. The puzzle setter provides some clues by placing some numbers in the grid. The difficulty of the puzzle depends on how many clues are given and how they are distributed.

How to Solve Sudoku Puzzles




Now that you know how to download sudoku games, you might be wondering how to solve them. Sudoku puzzles can be solved by using logic and deduction. You don't need any math skills or special knowledge to play sudoku. All you need is a keen eye and a sharp mind. Here are some tips and techniques to help you solve sudoku puzzles:


Sudoku Tips and Tricks




Before you start solving a sudoku puzzle, here are some general tips and tricks to keep in mind:


  • Scan the grid carefully and look for clues. Start with the rows, columns, and boxes that have the most numbers filled in.



  • Use pencil marks to write down the possible candidates for each empty cell. You can use numbers or dots to indicate the candidates.



  • Eliminate the candidates that are already present in the same row, column, or box. You can use cross-hatching or slicing and dicing methods to do this.



  • Look for patterns and relationships among the candidates. You can use techniques like naked pairs, hidden pairs, pointing pairs, box-line reduction, x-wing, swordfish, and more.



  • Check your work frequently and make sure you don't have any errors or contradictions. If you get stuck or make a mistake, you can use hints or undo your moves.



Sudoku Techniques and Strategies




To help you understand some of the common techniques and strategies for solving sudoku puzzles, here are some examples with illustrations:


Naked Pair




or box that have the same two candidates. These two candidates must be eliminated from the other cells in the same row, column, or box.


For example, in the image below, the cells marked with red circles have the candidates 2 and 6. These are naked pairs in the same box. Therefore, 2 and 6 can be eliminated from the other cells in the same box, as shown by the red crosses.


Hidden Pair




A hidden pair is a pair of cells in the same row, column, or box that have the same two candidates, but these candidates are also present in other cells. These two candidates can be eliminated from the other cells that contain them, leaving only the hidden pair.


For example, in the image below, the cells marked with green circles have the candidates 3 and 7. These are hidden pairs in the same column. Therefore, 3 and 7 can be eliminated from the other cells that contain them in the same column, as shown by the green crosses.


Pointing Pair




A pointing pair is a pair of cells in the same box that have the same candidate and point to the same row or column. This candidate can be eliminated from the other cells in that row or column.


For example, in the image below, the cells marked with blue circles have the candidate 9. These are pointing pairs in the same box that point to the same row. Therefore, 9 can be eliminated from the other cells in that row, as shown by the blue crosses.


X-Wing




An x-wing is a pattern of four cells that form the corners of a rectangle. These cells must have the same candidate and be aligned in two rows and two columns. This candidate can be eliminated from the other cells in those rows and columns.


For example, in the image below, the cells marked with purple circles have the candidate 5. These are x-wing cells that form a rectangle. Therefore, 5 can be eliminated from the other cells in those rows and columns, as shown by the purple crosses.


Swordfish




A swordfish is an extension of the x-wing pattern. It involves six cells that form the corners of a rectangle with an extra row and column. These cells must have the same candidate and be aligned in three rows and three columns. This candidate can be eliminated from the other cells in those rows and columns.


For example, in the image below, the cells marked with orange circles have the candidate 1. These are swordfish cells that form a rectangle with an extra row and column. Therefore, 1 can be eliminated from the other cells in those rows and columns, as shown by the orange crosses.
