You usually need a piece of Sudoku puzzle and a pen or pencil to write down the numbers. But now, technology has made playing Sudoku much easier and more accessible. You can easily play Sudoku Games Online.
Today’s article is about how you can play Sudoku online for free. Here is our list of The 17 Best Sudoku games online in 2022.
Sudoku
What is Sudoku? It is a question that might come to mind for those unfamiliar with the game. Simply put, it is a game of puzzles where a player has to fill a 9×9 grid with numbers so that each column and row has 3×3 sub-grids containing the numbers from 1 to 9.
The task has made it more difficult as some numbers are randomly pre-filled in the puzzles.
The Japanese first invented the Sudoku puzzles, which were called the number place back then. Maki Kaji, president of the Japanese Puzzle manufacturing company Nikoli,’ abbreviated the Japanese word Sūji wa dokushin ni kagura to English Sudoku.
The modern-day Sudoku was introduced in Dell magazine in the 19th century. In 1979 Del,l Magazines published a Sudoku puzzle designed by 74 years old architect Howard Garns.
Rules of Playing Sudoku
Playing Sudoku is not complicated, but you must have a good eye and understand numbers to solve the puzzle efficiently. There are some basic rules of Sudoku, and here they are:
- There are 9×9 grids, and inside that, there are 3×3 sub-grids. That divides the puzzle into 81 cells (nine rows and nine columns). You have to fill the cells with numbers.
- When filling the empty cells, you cannot use a number twice in the same row, column, or block.
- There will be at least 17- 30 pre-filled cells on the puzzle.
Solving a Sudoku Puzzle: Methods and Tips
Remember, every Sudoku puzzle has only one correct way to solve it, depending on the pre-filled cells. There are several techniques for solving the puzzle, but you don’t have to worry about them. If you are a beginner, we suggest you start with a puzzle with many cells pre-filled. It will be much easier for you to fill.
Start by identifying the missing sole numbers. Look in the row and column to find out which numbers are missing. Then cross-check if the missing number is in the next row or column. If you have found an isolated number, write it in the first blank cell. Following the same procedure fills the rest of the cells.
Use a pencil to write down the numbers. If you make any mistake, it would be easier to erase and redo the writing. Concentrate and remember to find the numbers from 1 to 9.
World Sudoku Championship (WSC)
Every year the World Puzzle Federation organizes the World Sudoku Championship. It is the ultimate competition for Sudoku players around the globe. In 2006 the 1st WSC was held in Lucca, Italy, and the most recent WSC was held in 2019 in Kirchheim, Germany. In 2022 the 16th WSC will be held in Shanghai, China. The competition is usually held in the ‘Individual and Team’ category. Japan is the most successful team in the World Sudoku Championship, securing victory in 2007, 2012, 2014, 2015, 2018, and 2019.
Creating a Sudoku Puzzle
To create a Sudoku puzzle at home, follow the following steps.
Step 1: Take a piece of a square sheet of paper, a pen/ pencil, and a ruler.
Step 2: draw a large square on the paper and divide the square into a 3×3 equal grid. You will get 9 smaller grids.
Step 3: Next, divide the 9 squares into 3×3 grids. Now you will have 81 small cells. Our puzzle cells are ready.
Step 4: Write down the numbers randomly in the 3×3 grid cells. Remember that every 3×3 grid should have numbers from 1 to 9.
Step 5: Finally, take an eraser and erase some numbers randomly, keeping 17- 25 numbers intact. Your Sudoku puzzle is ready.
