Sudoku is a popular pencil and paper game that many people enjoy. It is a logical puzzle that involves numbers and small grids. The game originated in Japan and has since spread throughout the world. Although Sudoku may appear difficult to solve, it is actually easy to play and an excellent exercise to boost your brainpower. In this article, we’ll discuss how to solve Sudoku puzzles in a systematic way.

The first step in solving Sudoku is to look for the clues given. The clues usually appear as numbers that are already filled in the grid. These numbers can be used as starting points for solving the rest of the puzzle. The numbers in the clues should be analyzed carefully as they can be used to unlock the rest of the grid.

The second step is to examine each row, column, and sub-grid to see which numbers are still missing. Rows, columns, and sub-grids cannot contain duplicate numbers, so each cell should be analyzed closely to see which numbers would fit into it. By doing this, you can reduce your options and eliminate numbers that do not fit.

The third step is to consider the numbers that are already filled in and what possible numbers can fit into the remaining spaces. This strategy is called “pencil marking.” It involves lightly marking the corners of each empty cell with the possible numbers that can fit into it. This will help in identifying the missing numbers in each row, column, and sub-grid.

The fourth step is to use logic and reasoning to solve the puzzle. This stage requires patience and concentration as you need to find the missing numbers while ensuring that each row, column, and sub-grid has no duplicate numbers. It is also essential to note that solving a Sudoku puzzle may require multiple passes to identify and fill in all the numbers correctly.

The fifth and final step is to do a final check of the entire grid. This will help to ensure that all the numbers are correctly filled, and there are no duplicate numbers in any row, column, or sub-grid. If any errors are found, go back and review steps four and three.

In conclusion, Sudoku is an enjoyable and stimulating puzzle that can be solved by following a few simple steps. The game is an excellent way to exercise your brain and improve your cognitive abilities. It is essential to remember that solving Sudoku requires patience, concentration, and logic. By following these steps, you can become a Sudoku master and solve even the most challenging puzzles with ease. Always remember to enjoy the game and have fun while you are at it. Happy Sudoku-solving!
