You gotta love Sudoku puzzles for all the good things they bring! Playing a puzzle per day helps increase your ability to focus and finish an actual task. Every time you complete a puzzle, your body releases Dopamine which boosts that feeling of self-accomplishment. With that, your confidence gets boosted and you become even more motivated to play!
