What is NYT Sudoku?

NYT Sudoku is a web-based Sudoku game that lets you play puzzles directly in any browser without signup or payment. It takes no input beyond your choices (mode, difficulty, cell entries) and outputs a completed or in-progress puzzle board. The puzzles are generated or stored by the site, using classic 9x9 Sudoku rules: each row, column, and 3x3 box must contain digits 1 through 9 exactly once. The game supports desktop and mobile layouts with a clean interface focused on the grid.

Key Features

• Three game modes — Level mode offers a fixed 200-puzzle progression from Easy (Levels 1-70) through Medium (71-140) to Hard (141-200). Daily mode gives one Easy, one Medium, and one Hard puzzle per date. Unlimited mode generates practice puzzles on demand at any difficulty.
• Note-taking — Toggle Notes mode to add or remove pencil marks in empty cells, helping you track candidates without cluttering the board.
• Hints, undo, and erase — Use hints to fill a single cell with the solution, undo recent moves, or erase a specific cell. Reset clears the current puzzle state while preserving fixed clues.
• Timer — A visible stopwatch tracks your solving time but has no effect on the puzzle; you can pause or return later.
• Local save — Guest games (including current puzzle, difficulty, notes, time, and stats) save automatically in your browser. Optional Google sign-in enables cloud sync across devices when production credentials are configured.
• Mobile-friendly — The board, toolbar, and keypad are designed for small screens without horizontal scrolling.

Who is it for?

• Beginners — Start with Level 1 or Easy Daily puzzles to learn the interface and basic row/column/box scanning without pressure.
• Daily habit solvers — Use Daily mode each day for a warm-up, main challenge, and optional hard puzzle; progress resets daily to match the date.
• Advanced players — Practice specific techniques or difficulty levels with Unlimited mode, or work through the 200-level progression to build stamina and candidate management skills.

What can you do with it?

• Warm up — Solve an Easy puzzle in Level or Unlimited mode to establish rhythm before tackling harder boards.
• Build a daily practice routine — Play one Easy, one Medium, and one Hard Daily puzzle each day; treat the set as a contained habit.
• Drill specific techniques — Use Unlimited mode at your chosen difficulty to repeatedly practice hidden singles, locked candidates, and note cleanup without waiting for new content.
