NYT Sudoku

NYT Sudoku is a free online Sudoku puzzle platform offering daily puzzles, a 200-level progression, and unlimited practice games, all playable directly in a browser without registration.

What is NYT Sudoku?

NYT Sudoku is an unofficial, independent web-based Sudoku game that lets players solve standard 9x9 puzzles in three modes: Levels, Daily, and Unlimited. It takes Sudoku grids with fixed clues and allows players to fill cells using logic. The platform runs entirely in a browser on desktop and mobile devices, with no download or account required. It is not affiliated with The New York Times Company.

Key Features

• Three game modes — Levels (200-puzzle progression from Easy to Hard), Daily (one Easy, Medium, and Hard puzzle per date), and Unlimited (on-demand generated puzzles at any difficulty).
• Notes system — Toggle notes mode to add pencil marks in editable cells, helping track candidates without memory load.
• Undo, erase, and hint — Undo recent moves, erase a single cell, or request a hint that fills the correct digit from the solution.
• Timer and reset — A session timer that does not affect puzzle state; reset clears all entered digits and notes while preserving clues.
• Local save and optional cloud sync — Guest progress (puzzle state, time, stats) saves automatically in the browser; optional Google sign-in enables cloud save when configured.
• Mobile-responsive interface — Board, toolbar, and keypad adapt to small screens without horizontal scrolling.
• Difficulty levels — Easy (levels 1-70), Medium (71-140), Hard (141-200) in Level mode; daily and unlimited also offer the three difficulty tiers.

Who is it for?

• Beginners — learn the rules and basic logic with Easy puzzles and the Levels progression.
• Daily habit players — complete a quick Easy-Medium-Hard set each day tied to the date.
• Experienced solvers — practice specific techniques using Medium or Hard unlimited puzzles and track improvement via timer and notes.
• Mobile users — play Sudoku on the go with the responsive layout.

What can you do with NYT Sudoku?

• Warm up quickly — Start an Easy puzzle and solve using only singles to build rhythm.
• Maintain a daily routine — Open the Daily mode each day for a set of three puzzles at increasing difficulty.
• Practice a specific technique — Use Unlimited mode to generate many puzzles at a chosen difficulty and drill note-taking or scanning habits.
• Resume a session later — Guest progress saves locally, so players can close the browser and return to the same puzzle.

How does it work?

Players choose a mode (Levels, Daily, or Unlimited) and a difficulty. The board displays fixed clues; empty cells are filled by selecting a cell and tapping a digit on the on-screen keypad. Notes mode adds pencil marks. Undo, erase, hint, and reset are available. Progress auto-saves locally, and optional Google sign-in enables cloud sync.

Pricing
