Our brain is like a muscle it thrives on regular exercise. In this guide, you’ll discover the best brain training games — games for the brain, from free online exercises to science-backed brain training apps. Learn how to choose the ones that truly support long-term brain health. We will break down the science of neuroplasticity in simple language and show you how to choose the right brain training game to boost your memory and focus. If you want a quick, ready-to-play list, start with these memory boosting games.

Brain training games are more popular than ever, and interest in cognitive exercise continues to grow. Importantly, scientific reviews of computerized cognitive training in older adults show measurable improvements in specific cognitive domains after training (i.e., you tend to improve what you practice). Large-scale survey research also shows that cognitively stimulating activities are widely recognized as protective for brain health—one open-access survey of adults 40+ in the UK and Ireland reported high awareness of cognitively stimulating activities as a protective factor (91%). For more details, see the review.

Many ask, “What are the best ways to boost brain health?” or “Can puzzles prevent dementia?” In this article, you will find expert opinions, solid research, and real-life success stories that explain how cognitive games help your brain.

What Are Brain Training Games?

Cognitive games are interactive activities that target your brain’s key skills. They include puzzles, brain training apps, and even strategic video games. These games challenge your memory, attention, and problem-solving abilities.

For example:

• Lumosity and BrainHQ turn simple lab tasks into engaging games.
• NeuroRacer uses multitasking challenges to improve focus.
• Classic puzzles like crosswords and sudoku have been popular for years.

These games go beyond mere entertainment—they are designed to improve your brain health through regular practice. You will see benefits from engaging in these activities, as they help build neural connections.

The Science Behind Brain Training Games

Our brain can change and grow. This is called neuroplasticity. Regular mental exercise helps build your “cognitive reserve,” a kind of mental savings account that protects your brain as you age. If your goal is sharper thinking overall, here are evidence-based ways to increase IQ through learning, challenge, and lifestyle. If you’re aiming for more forgetfulness in midlife, check out our guide to boosting your memory after 40 Research shows that playing games can even increase the thickness of your brain’s cortex. Several studies support this: a Nature study found that older adults who played NeuroRacer improved their multitasking skills, research on Tetris shows that long-term play boosts cortical thickness, and a 2021 study reported that speed-of-processing games may lower dementia risk by 29%. Experts like Daphne Bavelier and Adam Gazzaley also show that action video games enhance attention and multitasking by activating many parts of the brain and making processing more efficient.

If you wonder, “What is neuroplasticity?” or “How do brain games boost cognitive reserve?” the answer is simple: they train your brain to adapt and form new connections, which helps you think faster and better.

How Brain Training Games Boost Memory

How They Work

Cognitive games target core mental skills:

• Working Memory: Regular play improves your ability to hold and use information.
• Processing Speed: Games help your brain process information faster.
• Attention: They boost your focus and multitasking skills. If your main goal is a clearer head day to day, here’s how to gain mental clarity.

For example, the NeuroRacer study showed that older adults improved their multitasking by playing the game. Research indicates that lifestyle choices like gaming can explain up to 9% of differences in cognitive scores.

Transferable Benefits

There is debate on whether the skills you learn in games transfer to everyday life. Many experts agree that while you will get better at the game itself, building a strong cognitive reserve helps your overall brain function.

Long-Term Impact

Regular cognitive exercise may delay cognitive decline. Studies have found that older adults who engage in these activities can lower their risk of dementia over time. Combining brain games with other healthy habits builds a reserve that protects your mind as you age.

The ACTIVE Study (Advanced Cognitive Training for Independent and Vital Elderly)

The ACTIVE Study is one of the most significant and long-term randomized controlled trials conducted on cognitive training.

• This research, which followed nearly 3,000 older adults for up to 10 years, showed that participants who received speed-of-processing training (a type of brain training game) maintained significant long-term cognitive benefits.
• A 2017 follow-up analysis found that this specific training reduced the risk of developing dementia by 29% over 10 years for participants who completed the training regimen.

Boosting Working Memory and Attention

More recent research focuses on specific mechanisms of popular brain training apps and confirms targeted benefits of brain training games.

A study published in the International Review of Sport and Exercise Psychology found that computerized cognitive training consistently delivers significant improvement in specific executive functions, particularly working memory. You can read more in the 2022 network meta-analysis on CCT.

While games may not magically boost all aspects of life, they are highly effective at enhancing the core mental skill they are designed to target, which strengthens the overall cognitive reserve.
