"Playing strategic board games like Cylinder can also boost working memory and cognitive flexibility — the ability to adapt when plans change." A study in Frontiers in Human Neuroscience found that regular play of strategic games improves executive functions, which help with focus, decision-making, and creativity.

Cylinder isn’t just fun — it’s a real workout for your mind. The game’s wraparound design challenges players to picture moves from all directions, a skill scientists call mental rotation. Research shows that games involving mental rotation can strengthen the brain’s parietal lobes, which are important for problem-solving, spatial thinking, and planning ahead. One review found that: "Mental rotation tasks consistently activate these areas of the brain and improve spatial reasoning — skills used in fields like engineering, architecture, and even surgery."

"When I met my wife Diana, her father was working as a prop builder in the Los Angeles film industry. He was a hands-on, creative guy—worked with wood, metal, all kinds of materials. And one of the things he made was a hand-crafted, marble-based board game we just called 'The Marble Game.'

I met Diana in 1974, and during our early years dating, we’d spend evenings at her parents’ house, often playing that game together. I still have that original board—and we still bring it out for family and friends sometimes. It’s simple, fun, and it brings people together. And that whole experience—those evenings around a hand-built game—was the seed that eventually became CYLINDER.

This was his own design—invented somewhere from the late '50s or early '60s. Notice that it resembles some games you’ll still see around today, He often brought it to work and played it with co-workers. Perhaps only coincidentally, there now exist many similar games.
I wanted to keep that spirit alive, but take it further. Something more strategic, more abstract, more expandable. A game that still brings people together—but also pushes how we think and play.
