What are the benefits of playing Sudoku for your mental health? 

Sudoku is a fun pastime and a fantastic way to improve your brain function and overall mental health. Here are some of the benefits of playing Sudoku that will make you want to grab a pencil and get solving. 

Keeps your brain young 

As we age, our brains naturally become less efficient. However, playing puzzles like Sudoku can help slow down this process. According to a recent study, regular puzzle-solving boosts your brain function, making your brain age ten years younger than your actual age.

Improves cognitive function

When you solve Sudoku puzzles, you exercise your logical thinking and problem-solving skills. This can help your cognitive abilities. A study found a "close relationship" between the quality of cognitive ability and the frequency of completing puzzles like Sudoku for people aged between 50 to 93. 

Provides a sense of achievement

Solving more complex puzzles gives you a sense of achievement and pride. This feeling of accomplishment can benefit your mental health and keep you motivated to keep solving challenging puzzles.

Unlike other hobbies, Sudoku is also relatively easy and cheap to pick up. There are free apps available to help you get started and plenty of guides online. And if you prefer to work through your puzzles the old-fashioned way, there are also plenty of Sudoku books available on Amazon. 

What are the basic rules of Sudoku? 

To get started, it's essential to know the basic rules of Sudoku. First and foremost, let's talk about the format of the game. 

At its simplest, the puzzle is a 9x9 grid with squares arranged in a 3x3 configuration. The game's objective is to fill in the single squares with numbers from 1 to 9, ensuring that every number appears once in each row, column, and 3x3 square. For instance, you can't have two fives in the same row, column, or 3x3 square. 

The game gradually becomes more complex when numbers are filled into the grid, affecting the placement of other numbers in the remaining spaces.

With the basic rules in place, you can embark on a journey to conquer the game and enjoy the feeling of satisfaction that comes with it.

Sudoku strategies for beginner Sudoku players 

There are plenty of Sudoku-solving strategies you can employ as a Sudoku beginner to find the missing numbers. Check out our Sudoku tips to help you get started with this engaging number puzzle. 

Start by scanning the rows 

One of the easiest and most effective strategies for solving Sudoku puzzles is the scanning technique. You must scan rows and columns within each triple-box area, eliminating numbers or squares and finding situations where only a single number can fit into a square. This technique is a quick way to progress with puzzles when starting out. 

Use the process of elimination 

The process of elimination works well with more challenging puzzles. This technique involves eliminating values from the rows, columns, and boxes when a particular number is already occupied in a square. You can quickly identify where to place specific numbers by eliminating these values.

Use pencil marks 

Things can get complicated fast if you fill in a number you're unsure about and it turns out to be wrong. Using pencil marks is a great way to get around this issue without having to remember every possible number you think could work in a single square. 

The technique is simple. Focus on a single empty square. Look at the rows, columns, and block to determine the possible numbers that could go into that particular square. Then note down the numbers using light pencil marks and as small as possible so that you can fit in all the potential candidates. This will make it easy to erase the wrong numbers when determining the correct solution. 

Use a timer to make it more engaging 

While this is not a solving technique per se, using a timer can be a great way to make a Sudoku puzzle into more of a game. Record the time it takes to solve the puzzle, and then try to beat your score on the next one. See how fast you can solve the game as you learn new strategies. And why not get together with friends to make it an even more engaging competition? 

Sudoku: A fun hobby to keep your brain sharp
