Your brain is not done growing. That may sound strange, but it is true. Scientists once believed the brain stopped changing after childhood. We now know that is wrong. Your brain can build new pathways at any age. The trick is giving it the right kind of workout. Good news: the workout can be fun. Crosswords, cards, chess, and even a new hobby can all help keep your mind sharp. Let’s look at what actually works. It is backed by real research. Best of all, you can fit it into your week without spending much money.
What the Research Actually Shows
You do not need to take this on faith. Researchers have studied brain training for years, and the results are encouraging.
- One study looked at older adults who did just 5 to 6 weeks of computerized brain training. Twenty years later, they were 25% less likely to be diagnosed with Alzheimer’s disease. NBC News covered this research.
- People who stay mentally active are 14% to 42% less likely to develop memory loss, according to the Mayo Clinic.
- A study of over 19,000 people from the University of Exeter and King’s College London looked at this question. Regular crossword players delay memory decline by about 2.5 years. That is compared to people who never play at all.
- Researchers at McGill University studied older adults who played brain games for 30 minutes a day for 10 weeks. These adults had higher levels of acetylcholine in their brains. This is a chemical that helps you learn and remember.
These are not small effects. They add up to real protection for your memory and thinking skills. Before you start any new health routine, check with your doctor first. This includes any new exercise or activity plan.
Puzzles That Really Work
Not all puzzles are created equal. Some give your brain a bigger boost than others. Here are the two with the strongest research behind them.
Crosswords
Crosswords are one of the best-studied brain games out there. They ask your brain to do several things at once: recall words, spot patterns, and dig through your vocabulary. Mayo Clinic research even looked at digital crosswords. They helped people age 55 and older with mild cognitive impairment. They worked better than other computer games did.
You do not need a paid subscription. Many local newspapers print a free daily crossword. Your local library often has puzzle books you can borrow at no cost. The New York Times also offers a free daily crossword online.
Sudoku and Number Puzzles
Sudoku works a different part of your brain than crosswords do. It strengthens numerical reasoning and focus. The same 19,000-person study found that people over 50 who regularly played puzzles like Sudoku showed better brain function. The best part: even playing once a month made a real difference. Playing more often helped even more.
Card and Board Games
If you like playing with other people, this section is for you. Card and board games may be some of the best brain activities around, because they combine mental challenge with social time.
- Bridge: A University of Wisconsin-Madison study looked at bridge players age 55 to 91. They scored much higher on tests of working memory and reasoning than people who did not play. AARP has written about bridge as one of the best games for brain health.
- Chess: Research from the Carter Center looked at chess, bridge, and playing a musical instrument. All three are linked to a lower risk of dementia.
- Any card or board game: The University of Wisconsin also studied card and board games. Playing them is linked to greater brain volume. This happens in the very regions of the brain affected by Alzheimer’s disease.
Many senior centers host weekly card games or bridge clubs. Call your local senior center or check with your local library to find one near you.
Learn Something New
Puzzles and games are great, but learning a brand new skill may be even better for your brain. This is because learning something new forces your brain to build fresh connections, not just use old ones.
- A 2014 study in the Annals of Neurology looked at older adults who learned several new skills at once. Their thinking skills improved. They reached a level similar to adults in their 30s.
- More recent 2026 research found that learning a new skill after age 55 lowers the risk of cognitive decline by 23%.
- Learning a new language, even later in life, may slow age-related decline. This is true even if you never spoke a second language before.
What counts as a “new skill”? It could be:
- Learning to use a smartphone or tablet
- Taking a photography class
- Learning to paint, knit, or play an instrument
- Starting a language course, even a free one
Harvard Health notes that learning a genuinely new and challenging skill helps your brain more than doing something passive, like watching TV. The key word is “challenging.” Pick something that makes you work a little.
Free Apps and Offline Options
You do not need to spend money to give your brain a workout. Several apps offer free versions built on real science.
Apps to Try
- Lumosity – offers short daily brain games with a free tier
- Peak – built so you can finish a meaningful workout in under 5 minutes a day
- Elevate – focuses on reading, writing, and math skills
- BrainHQ – based on published neuroscience research
- AARP Staying Sharp – free for AARP members, with brain games and lifestyle tips
- MentalUP – offers puzzle and memory games with a free option
The good news is that you do not need a long session. Just 30 minutes a day was the amount linked to real brain chemistry changes in the McGill University study. But even 5-minute daily sessions on an app like Peak add up over weeks and months.
If You Prefer Offline Options
Not everyone wants to stare at a screen, and that is perfectly fine. You can get the same kind of benefit from:
- A daily newspaper crossword or Sudoku puzzle
- Puzzle books from your local library
- A deck of cards for solitaire, rummy, or bridge
- Board games like Scrabble, chess, or Rummikub
- Jigsaw puzzles at the kitchen table
Interestingly, research from the University of Wisconsin also found that everyday computer use, web surfing, and even watching movies gave some cognitive benefit. What seems to matter most is staying engaged, not the specific activity you choose.
Why Doing It With Other People Matters
Here is one of the most important findings from all this research. Activities you do with other people protect your brain more than activities you do alone. A solo game on your phone is good. A card game with friends is better.
Ohio State Health researchers studied learning programs that connect you with people of different ages. These programs boost both your thinking skills and your overall health. This is why a weekly bridge game may do more for your brain than an app. The same goes for a class at your local community college.
That does not mean apps are useless. They are simply one piece of the puzzle, not the whole picture.
A Simple Weekly Plan You Can Copy
You do not have to overhaul your whole life. Small, steady habits add up. Here are three real examples of how people fit brain-healthy activities into a normal week.
- The solo approach: One woman, age 72, plays a brain app for 10 minutes each morning. She also does the daily crossword. Once a week, she joins a bridge game at her senior center. Over six months, her crossword time dropped from 45 minutes to 30 minutes.
- The new-skill approach: A 65-year-old man took a beginner Spanish class at his local community college. He also plays online chess two to three times a week and does Sudoku over morning coffee.
- The couple’s approach: A retired couple started a weekly game night in their community, switching between bridge, Rummikub, and new board games. They also take a free digital photography class at their library.
Notice what each plan has in common: a mix of puzzles, social games, and something new to learn. That combination is where the real magic happens.
Key Takeaways

- Learning a brand new skill, such as a language or photography, may help your brain even more than passive games.
- Playing games or learning with other people gives you more protection than doing it alone.
- Free apps like Lumosity, Peak, Elevate, BrainHQ, and AARP Staying Sharp make it easy to start today.
- Aim for about 30 minutes of brain activity daily, but even 5 minutes counts if you stay consistent.
- Always combine brain games with exercise, good sleep, and a healthy diet for the best results.
Frequently Asked Questions
Will brain games prevent dementia?
Brain games can improve your thinking skills and may lower your dementia risk by 14% to 42%. But they cannot guarantee you will never develop dementia. Think of brain games as one part of a bigger plan that includes exercise, good sleep, a healthy diet, and time with friends.
Do crosswords and Sudoku really work, or is that just hype?
They really work. Peer-reviewed research shows crossword players delay memory decline by about 2.5 years. Sudoku strengthens numerical reasoning. The key is doing them regularly, ideally more than once a month, and pairing them with social activities when you can.
Is a brain-training app as good as playing cards with friends?
Playing cards with friends is likely better. Social time adds a powerful boost that apps alone cannot match. Apps are still valuable because they are easy to use every day. The best plan uses both: an app for daily consistency and in-person games like bridge or rummy for social connection.
I’m 68 and never learned a second language. Is it too late?
It is not too late. Research shows that learning a new language as an adult still helps protect your brain from decline. It does not matter what age you start. What matters is picking something new and challenging, whether that is a language, photography, or a musical instrument.
How much time do I need to spend on this each day?
Studies show real benefits from about 30 minutes of brain training a day. But do not let that number scare you off. Even 5-minute daily app sessions add up over weeks and months. The most important thing is doing it regularly, not doing it for a long time all at once.
Your mind has more room to grow than you might think, no matter your age. Start small. Pick one puzzle, one game night, or one new class, and build from there. Every crossword, every hand of cards, and every new skill you try is a gift to your future self.
