100+ Brain Games: Puzzles, Memory Tools, and More


Mental fitness is just as important as physical fitness, especially as you grow older. Playing musical instruments, socializing, engaging in physical exercise, and taking classes are just a few ways to keep your mind alert and engaged.

Brain games are another way to help keep your brain healthy. While your brain isn’t a muscle, it benefits from brain games such as logic problems, thinking games, brainteasers, non-traditional math, and other mental exercises.

Can Brain Games Improve Cognitive Health?

Brain games can contribute to cognitive health, but not on their own. Other activities—listening to music, exercising, maintaining proper nutrition, and having an active social network—are also essential to stimulating your brain and maintaining cognitive health. 

According to a study in the British Medical Journal, keeping your brain busy doesn’t stop cognitive decline, but it does give you a higher cognitive level from which to decline. Another study in Geriatric Nursing suggests games such as chess can help keep healthy cognitive, social, and psychological states while people age.
