In a distraction-heavy world, sustained concentration is rare. Sudoku trains structured attention because it demands continuous reasoning under strict rules.
1) Selective attention: filtering relevant information
2) Sustained attention: maintaining focus over time
3) Inhibitory control: resisting distractions and impulsive guesses
Sudoku often induces flow: clear goals, immediate feedback, and a balanced challenge-to-skill ratio. Flow supports deep, stable focus.
Many adults experience Sudoku as a mental reset: structured engagement instead of passive scrolling.
Sudoku won’t magically transform focus overnight, but consistent structured attention practice can improve concentration stability in analytical tasks.
