Playing brain-train games like Sudoku regularly can have a positive impact on your cognitive skills and activate different parts of your brain. Here’s what exactly happens in your brain:

Brain training boosts the prefrontal cortex
The prefrontal cortex is the front part of the brain and plays a crucial role in various cognitive processes and behaviors. It is known for its involvement in executive functions, which include skills needed to plan, organize, and perform complex tasks. When playing Sudoku, the prefrontal cortex becomes active for several reasons:
Problem-solving
Sudoku is essentially a puzzle that has to be solved by applying logical rules and strategies. You have to think about which numbers can be placed where and which numbers are already excluded based on the rules of the game. This requires using your problem-solving skills, which are partly managed by the prefrontal cortex.
Decision-making
While solving a Sudoku puzzle, you have to constantly make decisions about which numbers to fill in based on the information available. These decisions affect the progress of the puzzle, and your prefrontal cortex helps you make these decisions by evaluating possible options and choosing the best one.
Planning
When solving a Sudoku puzzle, it is often useful to have a plan, especially when the puzzle becomes more complex. You need to think about what steps to take to solve the puzzle and what strategies to apply. This process of planning and thinking of strategies also activates the prefrontal cortex.
Sudoku and similar puzzle games challenge the prefrontal cortex because they appeal to executive functions such as problem-solving, decision-making, and planning. By playing these games regularly, you can improve the activity and efficiency of the prefrontal cortex, which can lead to improvements in cognitive skills and general thinking ability.
Brain training boosts your memory
Our memory is an essential part of our cognitive functions and plays a crucial role in everyday mental tasks. It is your brain’s ability to temporarily hold and manipulate information. Playing Sudoku challenges your memory in several ways:
Temporarily holding information
To solve a Sudoku puzzle, you need to remember the numbers that have already been placed. This information is essential to avoid re-placing the same numbers in incorrect positions. It requires you to store in your memory which numbers have already been used and where they are in the grid.
Manipulating information
Besides memorizing numbers, you also need to keep in mind the possibilities for future moves. You need to think about which numbers could potentially be placed in certain positions and which numbers have already been ruled out based on the rules of the game. This manipulation of information in your mind is an important aspect of working memory.
Multi-tasking
Solving a Sudoku puzzle often requires you to think several steps ahead and consider different parts of the grid at the same time. This means you have to constantly retain and manipulate information as you gather new information and make decisions.
By playing Sudoku regularly, you train yourself to use your memory more effectively. You learn to hold and manipulate information quickly, which applies not only to the game itself but also to other aspects of your daily life. An improved memory can be useful in tasks such as remembering shopping lists, following instructions, and solving complex problems. It can also help improve concentration and cognitive flexibility, which is beneficial for all kinds of mental activities.
Brain training gives a boost to your pattern recognition
Sudoku, as well as all other similar puzzle games, helps improve your ability to recognize and apply patterns.
Pattern recognition
Sudoku is based on clear rules and patterns. For example, each row, column, and sub-grid must contain all the numbers from 1 to 9 without repetition. By playing Sudoku regularly, you gradually become familiar with these rules and begin to recognize patterns in the grid. For example, you learn that if a particular number already appears in a row, it cannot appear in the same row at a different position. This ability to notice regularities and repeating patterns in the puzzle stimulates the brain to actively engage in pattern recognition.
Applying logic
To solve a Sudoku puzzle, you need to use logical reasoning to identify and fill in missing numbers. This means not only recognizing existing patterns but also creating and applying new patterns to solve the puzzle step by step. The ability to apply logical reasoning to complex problems is an important part of cognitive skills, and Sudoku exercises this aspect excellently.
Cognitive flexibility
As you gain more experience with Sudoku, you will find that you can apply different strategies to solve the puzzle. This requires cognitive flexibility, which means being able to change approaches and try new strategies if one doesn’t work. Developing this flexibility can improve your overall problem-solving skills.
Puzzle games are thus excellent exercises for pattern recognition and applying logic. They challenge you to notice regularities and repetitive structures in the puzzle, strengthening your cognitive skills. These skills are not only applicable to solving puzzles but can also be useful in other situations where you need to recognize patterns, apply logical reasoning, and think flexibly.
Brain training is especially important in aging
It is known that the function of the prefrontal cortex generally declines as people age. This can accelerate if they do not engage in specific “brain training” activities. This decline in prefrontal cortex function is part of the normal aging process and can have several causes.
Natural reduction of neurons
As we age, some neurons in the prefrontal cortex may die off, and this can lead to a loss of connections between neurons. This can reduce the efficiency of the prefrontal cortex.
Changes in neurotransmitters
Aging can lead to changes in the levels of neurotransmitters, the chemical messengers in the brain. This can affect communication between neurons in the prefrontal cortex.
Reduction in plasticity
Plasticity refers to the brain’s ability to adapt and form new connections. As we age, the brain’s plasticity usually decreases, which can result in a reduced ability to learn and remember new information.
Changes in blood supply and metabolism
The prefrontal cortex requires good blood supply and optimal metabolism to function properly. Aging can cause changes in blood supply and metabolism, which can affect the prefrontal cortex.
Although the function of the prefrontal cortex may naturally decline as we age, lifestyle choices such as regular exercise, a healthy diet, and mental activities such as brain training games can help maintain and possibly even improve cognitive function. Much research has been done showing that certain forms of cognitive training and mental stimulation can help the prefrontal cortex stay active and slow cognitive decline. Here, results may vary from person to person.
Q&A
Question: How does playing Sudoku benefit cognitive function?
Answer: Playing Sudoku engages the prefrontal cortex, which is responsible for problem-solving, decision-making, and planning. It also enhances memory and pattern recognition, improving overall cognitive skills.
Question: Can Sudoku help improve memory?
Answer: Yes, Sudoku challenges your working memory by requiring you to remember numbers placed in the puzzle. This exercise can lead to improved memory not only in the game but also in daily life tasks.
Question: What cognitive skills does Sudoku enhance?
Answer: Sudoku enhances a range of cognitive skills, including problem-solving, logical reasoning, pattern recognition, and cognitive flexibility. It engages the brain in various ways to improve overall cognitive function.
Question: Is Sudoku effective in preventing age-related cognitive decline?
Answer: While Sudoku and similar brain-training activities can help maintain cognitive function in aging individuals, they may not completely prevent age-related decline. However, they can slow down the process and keep the brain active.
Question: Are there other activities besides Sudoku that can boost cognitive function?
Answer: Yes, activities such as crossword puzzles, chess, physical exercise, and learning new skills or languages can also enhance cognitive function and contribute to brain health. Variety in mental and physical activities is beneficial.
