## What Is Sudoku?

Sudoku is a logic-based, combinatorial number-placement puzzle. The objective is to fill a 9×9 grid with digits so that each same column, each row, and each of the nine 3×3 subgrids that compose the grid (also known as “boxes,” “blocks,” or “regions”) contain all of the digits from 1 to 9. The puzzle setter provides a partially completed grid, which for a well-posed puzzle has a unique solution.

Completed puzzles are always a type of Latin square with an additional constraint on the contents of individual regions. For example, the same single integer may not appear twice in the same row, column, or any of the nine 3×3 subregions of the 9×9 playing grid.

The game begins with some of the grid cells already filled in. Your goal is to fill in the empty cells with numbers from 1 to 9 according to the following rules:

- Each row must contain all of the digits from 1 to 9.
- Each column must contain all of the digits from 1 to 9.
- Each 3×3 subgrid must contain all of the digits from 1 to 9.

As a logic puzzle, Sudoku is also an excellent brain game. If you play Sudoku daily, you will soon see improvements in your concentration and overall brain power. Start a game now. Within no time, Sudoku will be your favourite free online game.

## How to Play Sudoku?

The goal of Sudoku is to fill in a 9×9 grid with digits so that each column, row, and 3×3 section contain all of the digits between 1 and 9. The steps include:

### Step 1: Find a Sudoku Puzzle

The first step to playing Sudoku is finding a puzzle. You can find Sudoku puzzles in newspapers, magazines, and online. Once you have found a puzzle, you are ready to start playing!

### Step 2: Understand the Rules

Before you start filling in numbers, it is important to understand the game’s rules. Each row, column, and 3×3 section in a Sudoku puzzle must contain all numbers from 1 to 9. Additionally, each number can only be used once in each row, column, or 3×3 section.

### Step 3: Begin Solving the Puzzle

Once you understand the rules of Sudoku, you can begin solving the puzzle! Start by looking for numbers that can only go in one spot. For example, if you see a row that contains the numbers 1, 2, and 3 but is missing the number 4, you know that 4 belongs in that row. You can use this same process to fill in other numbers until only one possible number is left for each spot.

## What Rules Do You Need To Follow?

Some general guidelines that will help you solve a Sudoku puzzle include:

### 1. Use Of 1-9 Numbers Only

You should only use the numbers 1 through 9 when playing Sudoku. The number 0 is not used in Sudoku. You will also find that some played Sudoku puzzles have extra clues, and they will also use the letters A through F. These are typically found in the diagonals of the puzzle.

### 2. No Guessing Allowed

Trying to guess the solution to a Sudoku puzzle is not allowed. If you find yourself guessing, starting over with a new puzzle is best. The whole point of playing Sudoku is to use logic and reasoning to solve the puzzle and the highlighted square, not guesswork.

### 3. Use Each Number Once In Every Row, Column And Sudoku Grid

Each row, column and grid must contain every number from 1 through 9. You cannot use the same number more than once in a row, column or grid.

### 4. Using The Elimination Process

The process of elimination is a very useful tactic for Sudoku beginners. When looking at a Sudoku puzzle, you should immediately start looking for numbers that can be eliminated from certain cells. For example, if you see a cell that can only be filled with a 4 or a 5, you know that it cannot be filled with any other number. This type of thinking will help you to solve the puzzle quicker.

### 5. Use Of Cross-Hatching And Penciling

Cross-hatching and pencilling in are two techniques that Sudoku players often use.

- Cross-hatching is when you focus on a 3×3 section grid. Also, you can draw a line through the cells containing a certain number. This helps you track which numbers have been used in a particular row, vertical column or grid.
- Pencilling in is when you write down the possible numbers that can go into a certain cell. This technique is often used when there are multiple possibilities for only cell.

Both of these techniques can be useful when solving Sudoku puzzles. However, it is important to use them sparingly. If you find that you are using these techniques too much, it may indicate that you are not approaching the puzzle correctly.

## FAQs

### 1. Are the Sudoku Rules Same for All Difficulty Levels?

The Sudoku rules are the same for all difficulty levels. The only difference is the number of pre-filled numbers in the puzzle.

An easy Sudoku puzzle will have a higher percentage of cells filled in, while a hard Sudoku puzzle will have a lower percentage of cells filled in.

### 2. What Is The Goal Of Playing Sudoku?

The goal of playing Sudoku is to fill in all of the empty cells on the board with the correct numbers. To do this, you must use logic and reasoning to figure out which numbers go where.

Sudoku is a great game for people of all ages. It can be challenging and frustrating at times, but it is also very rewarding. With a little practice, you will be able to solve Sudoku puzzles with ease.

### 3. What Is The 45 Rule In Sudoku?

The 45 Rule is a Sudoku strategy that can be used to help you solve the puzzle. The rule states that the total sum of each house must be 45. A house is defined as a row, column or 3×3 grid.

This rule can help you narrow down the possibilities for each cell. For example, if you know that the sum of a certain horizontal row must be 45, then you can eliminate any numbers that would cause the sum to exceed 45.

The 45 Rule is just one of many Sudoku strategies you can use to solve the puzzle. With a little practice, you can figure out which strategies work best for you.
