NYT Sudoku is one of the all-time most-played puzzle games offered by The New York Times. It is a great mental exercise as a logic game where you fill a 9×9 grid with numbers so that each row, column, and 3×3 square contains all digits from 1 to 9. Solving the Sudoku daily challenge will definitely make you smarter and more able to solve more of such problems, and even harder ones.
