Grandchildren keep you young. That’s what people say.
There might be truth to it. Engaging with young minds—answering endless questions, keeping up with their energy, adapting to their constantly shifting interests—is genuine cognitive exercise.
But you can also be more intentional about it. Here are ways to turn grandchild time into brain-healthy time for both generations.
A Note on What We’re Offering
We’re not child development experts. We make activity books for adults.
What follows are ideas we’ve gathered, not professional recommendations. Think of them as suggestions from fellow grandparents who want to stay engaged, not prescriptions from authorities.
Our products are designed for adult cognitive engagement. But we’ve noticed that some BrainArcade™ activities work well as intergenerational experiences. We’ll mention that where relevant, while being honest that it’s not the primary use case we designed for.
Strategy Games
Chess, checkers, and other strategy games exercise planning, foresight, and flexible thinking for both players.
Don’t let grandkids win automatically. Appropriate challenge promotes growth. Play at a level that stretches them without crushing them—and that keeps you engaged rather than coasting.
Board games with strategic elements—not just luck-based games—provide similar benefits. Settlers of Catan, Ticket to Ride, and similar games require planning and adaptation.
Brain benefit for you: Strategy games exercise executive function, planning, and cognitive flexibility. Real opponents provide unpredictability that solo activities can’t match.
Word Games
Scrabble, Boggle, word association games, storytelling games. Language-based play exercises vocabulary, verbal fluency, and creative thinking.
Make up games on the fly: “How many words can you think of that start with B and relate to breakfast?” Spontaneous word games work while traveling, waiting, or filling time.
Brain benefit for you: Word games exercise language processing, retrieval, and verbal creativity. Teaching vocabulary to children reinforces your own knowledge.
Puzzle Collaboration
Work on puzzles together. Jigsaw puzzles, logic puzzles, brain teasers.
Collaborative puzzling models problem-solving strategies. Children see how you approach challenges—where you start, how you handle frustration, when you take breaks.
Some BrainArcade™ activity pages work well collaboratively. Adult solves one part, child (depending on age) contributes to another. Not designed for kids, but adaptable for shared time.
Brain benefit for you: Collaborative solving often surfaces different approaches than solo solving. Teaching others requires deeper processing of your own strategies.
Memory Games
Classic memory card games. “I went to the market and bought…” chains. “What’s different?” observation games.
Memory games level the playing field somewhat—children often have excellent rote memory, while adults bring strategic approaches. Both generations get challenged.
Brain benefit for you: Memory games directly exercise encoding and retrieval. Playing with children adds social pressure that increases cognitive demand.
Question Games
Children ask endless questions. Turn it around: you ask questions too.
“What would happen if…?” hypotheticals exercise imagination and logical thinking. “How does this work?” questions prompt explanation (and explaining is cognitive exercise). “What do you think about…?” questions develop perspective-taking.
Brain benefit for you: Generating good questions is cognitively demanding. Listening carefully to answers exercises attention. Following up requires flexible thinking.
Teaching Moments
Teaching is one of the most cognitively demanding activities there is.
When you teach a grandchild something—how to cook, how to play an instrument, how to build something, how anything works—you’re exercising explanation, patience, adapation to feedback, and deep knowledge retrieval.
Don’t just do activities with grandchildren. Teach them things. The teaching itself is brain exercise.
Brain benefit for you: Teaching requires understanding material deeply enough to simplify it. That depth of processing is valuable cognitive work.
The Real Point
These specific games matter less than the general principle: engaged interaction with grandchildren is cognitively valuable.
Not passive watching. Not handing them a screen. Active, demanding, two-way engagement.
You benefit. They benefit. The relationship benefits.
And unlike solo brain training, this kind of engagement creates memories. Decades from now, your grandchildren will remember the games, the conversations, the time you spent actually being with them.
That’s worth more than any puzzle score.
Play Smarter. Stay Sharper. Longer.
