About 30% of all people who play video games are over 50, according to the Entertainment Software Association’s most recent data. Among baby boomers specifically, 65% say one of their main reasons for playing is to keep their minds sharp. The question worth asking is whether the games are actually doing that. The honest answer from current research is: it depends on what you play, and the evidence is promising but not settled.
What the research shows
A 2025 meta-analysis in Frontiers in Aging Neuroscience examined video game interventions in older adults with mild cognitive impairment and found that games improved global cognitive functioning, working memory, and executive function. The researchers concluded that games may have meaningful preventive value in slowing progression toward dementia. That is a significant claim, and one supported by multiple individual studies in the analysis.
A separate 2025 longitudinal study published in the Journal of Medical Internet Research found that cognitively active digital activities, including video games, were associated with reduced dementia risk. Passive digital activities, such as watching television, were associated with increased risk. The distinction the researchers draw is between active and passive engagement: games that require decisions, planning, or pattern recognition appear to do more than activities where you are mostly watching something unfold.
That said, the research is not unanimous. Some meta-analyses have found that game-based cognitive training failed to produce measurable improvements in real-world cognitive tasks. Benefits observed in controlled settings do not always transfer outside them. Treat the evidence as promising rather than proven.
Which types of games the research focuses on
Puzzle games, strategy games, and 3D platform games appear most consistently in the research literature. Studies from McGill University found that regular play of 3D platformers was associated with increased grey matter in the hippocampus, the region of the brain most central to memory. Crossword puzzles have a longer research history: one study found consistent crossword completion may delay memory decline by roughly two and a half years.
Games that involve planning, recall, and attention appear to do more than reflex-based games. Chess, bridge, Sudoku, and word games appear regularly in the literature as beneficial. On the digital side, Lumosity and BrainHQ are the most widely studied brain-training apps. Their specific claims about real-world cognitive transfer have faced scrutiny over the years, so their value may lie more in providing a consistent daily habit than in any specific training effect.
Good starting points if you are new to gaming
These titles are beginner-friendly, low-friction, and match the game types that appear most in the research:
- Monument Valley (iOS, Android) — A short, visually beautiful puzzle game built around spatial reasoning. Free to try, paid to complete the full game.
- Lumosity (iOS, Android, browser) — A brain-training app with short daily sessions targeting memory, attention, and processing speed. Free at the basic level.
- Sudoku and crossword apps — Available free through the New York Times app or dozens of standalone apps. Low barrier to entry, well-studied for cognitive benefit.
- Chess.com (browser, iOS, Android) — Free at the base level, with puzzles and games against the computer at adjustable difficulty. One of the most widely used chess platforms in the world.
These are starting points, not limits. If you find a genre you enjoy, the evidence suggests that sustained engagement matters as much as the specific game type.
How much and how often
Most researchers suggest 20 to 30 minutes of cognitively active play on most days as a reasonable baseline. Consistency appears to matter more than session length. Varying what you play also seems to produce better outcomes than repeating the same game until it becomes automatic. Once a task becomes routine, it stops presenting the kind of challenge that stimulates the brain.
For many older adults, gaming also carries a social dimension. The ESA reports that among boomers and the Silent Generation, playing with family members and sharing progress with others is a significant part of why they play. Social engagement carries its own well-documented cognitive benefits, independent of the games themselves.
The bottom line
Video games are not a guaranteed protection against cognitive decline. Anyone presenting them as such is overstating what the research currently shows. What the evidence does suggest is that active, engaging games can support cognitive health as part of a broader approach that includes physical exercise, quality sleep, and social connection. The National Institute on Aging has described video games as showing potential for improving memory in older adults experiencing age-related decline. That is cautious language from a credible source, and it is probably where the honest confidence level sits right now.
