Sudoku is a number puzzle game that is very popular all over the world. The game challenges players to fill a 9×9 grid with numbers from 1 to 9, in such a way that each number appears only once in each row, column, and 3×3 subgrid. For those of you who are new to the game, here is a complete guide on how to play Sudoku.
A Brief History of Sudoku
Before we get into how to play, it’s worth knowing a little bit about the history of Sudoku. Sudoku has deep roots, originating in Japan, although the game was inspired by older number puzzles from Europe and America. It first appeared in its modern form in 1984 when the puzzle’s creator, Howard Garns, introduced “Number Place.” Sudoku then became extremely popular around the world, especially after being introduced by a Japanese newspaper in 1986.
Sudoku Structure and Basic Rules
Before starting the game, it is important to understand the basic structure of the game. Here are some important points in the structure and rules of the Sudoku game:
-
Grid 9×9: Sudoku consists of a grid divided into 9 rows and 9 columns. This grid is also divided into 9 3×3 subgrids.
-
Numbers 1-9: In Sudoku, you have to fill the numbers from 1 to 9 into the grid.
-
Placement Rules: Each number can only appear once in each row, column, and 3×3 subgrid. This is a basic rule to follow.
- Filled Cells: Some numbers will be already filled in the grid as clues, and your task is to fill in the blank numbers based on the applicable rules.
How to Play Sudoku Step by Step
Here are the steps you can follow to play Sudoku:
1. Understanding the Grid
Before you start playing, understand the grid you see. Observe the numbers that are already there and note their position and distribution.
2. Start with a Certain Number
Focus on the existing numbers. Try to determine which numbers can be filled in the empty positions. The way to do this is by looking at the rows, columns, and subgrids of the existing numbers.
3. Use the Process of Elimination
One effective way to fill in numbers in Sudoku is to use the process of elimination. Here's how to do it:
4. Train Logical Skills
Sudoku is not just about recognizing numbers, but also training your logic skills. The more you play, the better you will be at solving these puzzles.
5. Use Specific Techniques
In the game of Sudoku, there are several techniques that can help you find the correct number. Here are some of them:
-
Naked Singles: This occurs when there is only one number that can be entered into a cell. If you encounter this, immediately fill in the number.
-
Hidden Singles: While there are multiple possible numbers in a particular cell, one number may only match that cell. These are often harder to find than Naked Singles.
-
Pointing Pairs: When two numbers in a subgrid force the same number to be in one row or column, you can exclude that number from other cells in the same row or column.
- Box-Line Reduction: If a number appears in a row in two subgrids, it can be excluded from other cells in that row that are not in the subgrids.
Tips for Beginner Sudoku Players
Here are some tips for beginner Sudoku players to help you while playing:
-
Start with the Easy: Choose a puzzle with a lower level of difficulty. This will help you understand the mechanics of the game.
-
Make a Note: While working on the puzzle, make notes on the edges of the cells to indicate possible numbers that can be put together. This will help you in the process of elimination.
-
Stay calm: Don't rush. A small mistake can lead to a bigger confusion.
-
Practice Often: The more you practice, the better you will be at solving puzzles. Try to play every day.
