What Brain Training Games Are and How They Work

Brain training games are puzzles, memory challenges, and mental exercises designed to stimulate different areas of your thinking. These games target skills like memory, attention, problem-solving, and processing speed. They come in many forms—some are traditional games like chess or crosswords, while others are digital apps that track your performance over time.

The basic idea behind brain training is that your brain works like a muscle. When you use it in new ways or push it with challenging tasks, it can adapt and strengthen. This concept is called neuroplasticity, which research shows is real. Your brain can form new connections throughout your life, even in older age. Brain training games attempt to use this principle by giving your brain structured, repeating mental challenges.

Most brain training games follow similar patterns. You start with a baseline level, then the difficulty increases as you improve. Games track metrics like how fast you answer, how many you get right, and how your performance changes over weeks and months. Some popular types include:

• Memory games where you match pairs or recall sequences
• Attention games that test focus and reaction time
• Logic puzzles that require reasoning
• Speed games that measure how fast you process information
• Language games that build vocabulary and word skills

The research on whether brain training games actually work is more complicated than marketing claims suggest. Studies show that people do get better at the specific games they practice. This is called task-specific improvement. However, whether this improvement transfers to other thinking skills or real-world activities remains unclear in much of the research.

Practical Takeaway: Brain training games can be an enjoyable mental activity, but understand that getting better at a specific game doesn't automatically mean your overall thinking will improve in other areas. Think of them as a workout for specific mental skills rather than a cure-all.

What Current Research Shows About Brain Training Effectiveness

Scientific research on brain training has been ongoing for about two decades, and the findings are nuanced. A major 2016 review published in the journal Psychological Bulletin examined over 600 studies and found that while people improve at the games they practice, there is limited evidence that this improvement transfers to other cognitive tasks or daily life performance.

The National Institute on Aging conducted a large study called ACTIVE (Advanced Cognitive Training for Independent and Vital Elderly) that tracked over 2,800 older adults. Participants who completed cognitive training showed improvements in the specific skills they trained—memory, reasoning, or processing speed. However, ten years later, the study found that training delayed cognitive decline by about three to five years for reasoning and processing speed, but not for memory. This is meaningful but not a dramatic reversal of aging.

One consistent finding across research is that brain training works best when:

• Training is difficult and progressively challenging
• The same skill is practiced repeatedly over weeks or months
• Training sessions are long enough (not just five minutes daily)
• The person is motivated and engaged
• The specific skill being trained is relevant to what you want to improve

Some brain training games claim to improve general intelligence or prevent dementia. These claims go beyond what research supports. A 2019 study in Frontiers in Aging Neuroscience found that cognitive training did not prevent or delay the onset of dementia, though it may help maintain function in people already diagnosed. This is an important distinction. The research also shows that training effects often fade if you stop practicing, similar to physical fitness.

Interestingly, research shows that many non-digital activities may be just as effective as brain training games. Playing chess, learning a new language, reading challenging books, or taking up a musical instrument all involve cognitive challenge. A 2018 study in PLOS One found that older adults who engaged in cognitively demanding hobbies like painting, writing, or puzzles had better cognitive function than those who didn't, regardless of whether those hobbies were digital.

Practical Takeaway: Research suggests brain training games can improve specific mental skills you practice, particularly reasoning and processing speed. However, benefits are most likely when training is challenging, sustained over months, and combined with other healthy habits like physical exercise, sleep, and social activity.

Different Types of Brain Training Games and What They Target

Brain training games vary widely in their design and the mental skills they target. Understanding what each type does can help you choose games that match what you want to work on.

Memory Games focus on your ability to retain and recall information. Classic memory card games require you to remember where cards are located and match pairs. More advanced versions might involve remembering sequences of numbers, words, or images that appear briefly. Research shows that memory training can improve performance on similar memory tasks, but whether it transfers to everyday memory (like remembering where you put your keys) is less clear. A study in the Journal of Applied Research in Memory and Cognition found that memory training helped people remember the trained material but didn't significantly reduce everyday memory problems.

Attention and Concentration Games train your ability to focus on relevant information while ignoring distractions. These games might require you to track a moving object, spot differences between images, or respond quickly to specific targets while ignoring others. Research from the University of California found that attention training in older adults improved their ability to filter out distractions in controlled settings, though real-world benefits were modest.

Processing Speed Games challenge how quickly you can understand and respond to information. These often involve fast-paced tasks where you need to match patterns, answer questions, or make decisions rapidly. The ACTIVE study mentioned earlier found that processing speed training showed measurable benefits for older adults, with improvements lasting up to ten years in some cases.

Reasoning and Problem-Solving Games involve logic puzzles, pattern recognition, and strategic thinking. Examples include Sudoku, chess, and games requiring you to deduce answers from clues. These games tend to show good research support for maintaining cognitive function, particularly in older populations.

Language and Vocabulary Games build word knowledge and language skills. Crosswords, word searches, and games that require matching words to definitions fall into this category. Research in Psychology and Aging found that vocabulary training maintained and sometimes improved language abilities in older adults.

Many popular brain training apps combine these types into a collection of mini-games. Examples include Lumosity, Peak, and Elevate. These apps typically track your performance across different game types and adjust difficulty based on your scores.

Practical Takeaway: Different game types train different skills. If you're interested in brain training, choose games that target the specific abilities you want to work on, whether that's memory, attention, speed, reasoning, or language skills.

How to Evaluate Brain Training Games and Claims

With hundreds of brain training apps and programs available, knowing which ones are backed by solid thinking is important. Many brain training products make bold claims about improving your intelligence, preventing dementia, or transforming your cognitive abilities. Understanding how to evaluate these claims can help you make informed decisions.

One common claim is that a game or program is "scientifically proven" or "based on research." This phrase can be misleading. Look for specific details: What research? What did it actually find? Was the research published in a peer-reviewed journal? A 2015 analysis in Current Biology reviewed research on commercial brain training programs and found that while some training showed benefits in controlled research settings, the real-world benefits were often much smaller than advertised.

Be cautious about these common claims:

• "Prevents dementia" — Research does not support this. Brain training may help maintain function but cannot prevent dementia.
• "Increases IQ" — Brain training improves specific tasks, not general intelligence.
• "Works for all ages" — Benefits vary widely by age, health status, and existing cognitive abilities.
• "Just minutes a day" — More effective training typically requires longer sessions practiced over months.
• "Endorsed by neuroscientists" — Check who specifically endorsed it and whether they have financial ties to the company.

When evaluating a brain training program, consider these questions: Does the company provide references to published research? Is that
