Every morning, I sit down with my cup of coffee, open up the New York Times Games app on my phone, and do the Wordle, Connections, Strands, and Mini-Crossword, in that order. As I complete each game, I send my results to the "Puzzle Pals Gang" group chat I have with some friends and family. We compare. We gloat. We trash talk. We congratulate. It's a delightful routine.

And we're not the only ones. According to the New York Times, there were 4.8 billion plays of Wordle, 2.3 billion plays of Connections, and 8 billion game and puzzle plays total in 2023. A whole lot of people love their brain games.

I like to think I'm benefiting from a nice little brain workout when I do those puzzles, but am I really? According to Mark Alberts, MD, chief of neurology at Hartford Hospital and co-physician-in-chief at the Ayer Neuroscience Institute, I probably am—but that doesn't mean everyone else is.

"These sorts of brain exercises can be very helpful for improving your ability to think and remember,” Alberts says, but that's only true if you're someone who actually likes and enjoys doing them. People who find the games fun can enjoy a boost in memory, attention and other cognitive functions. But for those who just find them stressful or frustrating, the cognitive benefit doesn't outweigh the negative impacts.

“Sure, crossword puzzles and Sudoku could be fun for some people. But if they’re distressing to you—or just not fun—they won’t be beneficial,” says Dr. Alberts.

As someone who loves games and puzzles, I'm surely reaping the cognitive benefits. Someone who gets super stressed out by them would not, but that doesn't mean there aren't other ways for people who don't enjoy games to give their own brains a boost.

“Emotional well-being has a huge impact on cognition, so it’s important to choose activities that give you joy,” says Dr. Alberts. “Find a different hobby. Take a class. Teach a class! Keep learning in other ways.”

And, of course, there's not widespread agreement on the degree to which these games are helpful to brain health, either. Susanne Jaeggi, a professor with the Center for Cognitive and Brain Health at Northeastern University, says that the games being good for brains question isn't that simple.

“There are a lot of different things that contribute to our brain health," Jaeggi says. "As long as you’re doing something that keeps your brain engaged and fit, that could potentially be helpful to prevent age-related cognitive decline. Whether it’s exactly these games, that’s an open question, because a lot of these are new and there’s not a lot of (research) out there.”

A big question people have is whether games can help ward off age-related cognitive issues and dementia diseases. While Alberts says there’s no evidence for brain games preventing or delaying the onset of dementia, certain games do utilize cognitive functions that tend to diminish with age. “Fluid functions” like problem-solving, processing speed, and working memory tend to wane as we age, and some of the NTY Games puzzles force your brain to perform those functions.

A study published in NEJM EvidenceNEJM Evidence found some evidence that crossword puzzles can have a positive impact on aging brains. The study found that people age 62 to 80 with mild memory problems who played web-based crossword puzzles showed improved cognition and less brain shrinkage than to those who played web-based cognitive games.

However, crossword puzzles largely draw on things we already know, which is different than making our brains do something new or solve problems. “All your knowledge that you accumulate as a result of expertise and education, these are skills that remain as we age,” Jaeggi said. “Things like crossword puzzles that have you retrieve this accumulated knowledge, that’s not typically something that declines with age.”

One way to keep our brains sharp as we age is to try new things, and games can be a part of that. “What seems to be the case is that if you learn new skills and they’re challenging at whatever level of challenge is appropriate for you, then you see benefits,” said Art Kramer, psychology professor and director for Northeastern University's Center for Cognitive and Brain Health. “So if you’ve never done crossword puzzles or you’ve never played (Sudoku), that might be of benefit to you.”

Novel and enjoyable seem to be the key, so if games are your thing and you want to reap the benefits, enjoy the puzzles you love but also try some new ones once in a while.
