Sudoku is often called “brain training.” It does stimulate key cognitive skills—but it’s not magic. The most realistic view is: Sudoku supports structured thinking and mental engagement, with benefits strongest in domains it directly trains.
Mentally stimulating activities are associated with better cognitive maintenance compared to inactivity. Sudoku can be one part of a broader “brain-healthy” lifestyle.
10–20 minutes per session, several times per week, consistently over months.
Sudoku is a legitimate cognitive workout for logic and attention. Treat it as a helpful habit—especially when combined with other healthy routines—not a miracle cure.
