Scientific evidence confirms it: Mahjong is good for your brain.
A decade-long study tracking over 7,500 older Chinese adults revealed that regular Mahjong players had significantly better cognitive scores than those who didn’t play.
The more often they played—especially daily—the better they performed in memory, attention, reaction speed, and coordination.
From 2008 to 2018, those who didn’t play Mahjong showed a faster and sharper decline in brain function.
Even more compelling, the study found that Mahjong actually helped improve or preserve cognition—not just that smart people played more. In short, it was Mahjong helping the brain, not the other way around.
Why is it so effective? Because Mahjong is both mentally and socially engaging. It taps into several cognitive skills at once, including:
Memory and attention
Logical thinking and pattern recognition
Language, judgment, and decision-making
