Sudoku May Put Your Brain into a State of Flow
Have you ever started a Sudoku puzzle and suddenly realized an hour has passed? Psychologists call this experience "flow"—a state of deep concentration in which people become so absorbed in an activity that they lose track of time. Sudoku can encourage this experience because it offers a steady stream of small challenges, discoveries, and satisfying breakthroughs.
