NYT Sudoku

NYT Sudoku is a free, fast, and newspaper-style online Sudoku game. It offers three main modes: Levels (200 structured puzzles from Easy to Hard), Daily (one Easy, one Medium, one Hard puzzle per date), and Unlimited (generated practice puzzles on demand). The board supports note-taking, hints, undo/erase, and a timer. Guest progress is saved locally; optional Google sign-in enables cloud sync. The interface is designed for both desktop and mobile, with a clear layout that prioritizes the puzzle. No account or payment required to play.
