The Basics of Sudoku
Sudoku is a logic-based puzzle game that’s played on a 9×9 grid. The goal of the game is to fill in the grid with numbers so that each row, column, and 3×3 box contains all of the numbers from 1 to 9.
Each puzzle starts with some numbers already filled in. These numbers are called "givens." The rest of the puzzle is blank, and it’s up to you to fill in the missing numbers.
How to Solve a Sudoku Puzzle
To solve a Sudoku puzzle, you need to use logic to deduce the missing numbers. Here are some strategies you can use:
1. Look for Naked Singles
A naked single is a number that can only go in one square. For example, if a row contains the numbers 1, 2, 3, 4, 5, 6, 7, and 9, then the only possible number for the remaining square is 8.
2. Look for Hidden Singles
A hidden single is a number that can only go in one square, even though it’s not immediately obvious. For example, if a row contains the numbers 1, 2, 3, 4, 5, 6, and 8, then the only possible number for the remaining square is 9, even though it’s not the only number that’s missing from the row.
3. Use the Process of Elimination
The process of elimination is a technique where you eliminate all of the possible numbers for a square. For example, if a row contains the numbers 1, 2, 3, 4, 5, 6, and 7, then the only possible number for the remaining square is 8 or 9. You can eliminate 8 because it’s already in the column, so the only possible number is 9.
4. Guess and Check
If you’re stuck, you can always guess and check. However, this is not the best strategy, as it can lead to mistakes. If you do guess and check, be sure to write down your guesses so that you can keep track of them.
Tips and Tricks for Solving Sudoku Puzzles
Here are a few tips and tricks to help you improve your Sudoku game:
1. Start with the easiest squares
The easiest squares to fill in are the ones that have the most givens. Start by looking for squares that have only one or two possible numbers.
2. Don’t be afraid to make mistakes
Everyone makes mistakes when solving Sudoku puzzles. If you make a mistake, just erase it and try again.
3. Take your time
Sudoku is a game that requires patience and concentration. Don’t try to rush through it. Take your time and work through the puzzle one step at a time.
4. Have fun!
Sudoku is a game that’s meant to be enjoyed. Don’t get frustrated if you can’t solve a puzzle right away. Just relax and have fun with it.

FAQ about Sudoku
What is Sudoku?
Sudoku is a logic-based puzzle where you have to fill in a 9×9 grid with numbers from 1 to 9. Each row, column, and 3×3 box must contain all the numbers from 1 to 9 without any repeats.
How do you play Sudoku?
Start by looking for rows, columns, or boxes that already have most of the numbers filled in. From there, you can use logic to deduce which numbers should go in the remaining empty cells. If you get stuck, you can make educated guesses and use trial and error to find the solution.
What are the rules of Sudoku?
- Each row must contain all the numbers from 1 to 9.
- Each column must contain all the numbers from 1 to 9.
- Each 3×3 box must contain all the numbers from 1 to 9.
- No number can repeat in the same row, column, or box.
How do I solve a Sudoku puzzle?
Most Sudoku puzzles can be solved using a combination of logic and guesswork. Start by looking for rows, columns, or boxes where most of the numbers are already filled in. Then use logic to deduce which numbers must go in the remaining empty cells. If you get stuck, you can make educated guesses and use trial and error to find the solution.
What is a hidden single?
A hidden single is a number that can only go in one of the empty cells in a row, column, or box. To find a hidden single, look for places where a particular number is already in most of the cells of a row, column, or box. The only remaining empty cell in that section must be filled with that number.
What is a naked pair?
A naked pair is two of the same number in the same row, column, or box. When you find a naked pair, you know that those two numbers cannot go in any other empty cells in that section.
What is a pointed pair?
A pointed pair is a pair of numbers that appear in the same row or column, but only in two boxes. When you find a pointed pair, you know that those two numbers cannot go in any other empty cells in those two boxes.
How do I solve a Sudoku puzzle with trial and error?
If you get stuck, you can try using trial and error to find the solution. Make an educated guess and fill in an empty cell with a number. If the number works, continue filling in the puzzle. If the number doesn’t work, erase it and try another number.
What are some tips for solving Sudoku puzzles?
- Start by looking for rows, columns, or boxes where most of the numbers are already filled in.
- Use logic to deduce which numbers must go in the remaining empty cells.
- Look for hidden singles, naked pairs, and pointed pairs.
- If you get stuck, use trial and error to find the solution.
- Don’t be afraid to erase and start over.
