NYT Sudoku Guide: Rules, Difficulties, Hints & How to Play

NYT Sudoku is the daily number-placement puzzle published by The New York Times Games. Each day brings three new puzzles in Easy, Medium and Hard difficulties, free to play on the NYT Games website and in the NYT Games app. The goal is to fill every row, column and 3×3 box with the digits 1 to 9, with no repeats.

What Is NYT Sudoku and Where Can You Play It?

NYT Sudoku is the New York Times' take on the classic logic puzzle. Like all sudoku, it runs on one simple rule: a 9×9 grid must be completed so that every row, every column and each of the nine 3×3 sub-grids contains the digits 1 to 9 exactly once. No arithmetic is involved – it is pure logic.

The official NYT Games app describes its Sudoku as "a numbers game, minus the math," with a new puzzle every day in easy, medium or hard mode (play.google.com). You can play it in two places:

• The NYT Games website – find Sudoku in the games section alongside Wordle, Spelling Bee, Connections and the Mini Crossword.
• The NYT Games app – free to download on iOS and Android, and playable on desktop browsers too. The app is completely ad-free, so nothing interrupts your solving.

Because the puzzle is published by one of the world's most recognised news brands, the presentation is polished: a clean grid, smooth number entry on touchscreens and keyboards, and a consistent daily release schedule that makes it easy to build into a routine.

NYT Sudoku Difficulty Levels

Unlike some sudoku apps that offer five or six tiers, NYT Sudoku keeps it simple with three difficulty levels (gameerrors.com):

Easy

Easy puzzles start with plenty of givens (pre-filled numbers), so most cells can be solved with straightforward singles. If you are new to sudoku, this is where to start – you can make fast progress just by scanning rows, columns and boxes for obvious placements.

Medium

Medium puzzles give you fewer starting numbers and introduce trickier patterns. Roughly equal numbers of filled and empty cells, according to player guides, means you will need pencil marks and techniques like hidden singles to get through (gameerrors.com).

Hard

Hard puzzles open with a sparse grid and demand advanced logic – candidates tracking, pointing pairs, and pattern techniques such as X-Wing. They are a proper workout even for experienced solvers, and one careless guess can cost you.

One practical note: harder grids are not just about fewer clues, but about how the clues interact.

How to Play: NYT Sudoku's Interface and Features

The NYT Sudoku board works the way you would expect, but a few built-in tools set it apart from a paper grid:

• Normal vs Candidate mode. Enter numbers you are confident about in normal mode; switch to candidate (pencil-mark) mode to note the possible values for an unsolved cell. On desktop, pressing Space toggles between Fill and Candidate mode, and 'N' toggles notes (monktech.net).
• Auto-Check. If you enable automatic checking, an incorrect entry is flagged immediately with a red dot in the bottom-right corner of the cell (gameerrors.com). Leave it off for a purer, paper-like challenge where you must spot your own mistakes.
• Hint button. Stuck? The Hint button highlights the next logical square to solve – an empty cell you should tackle next, or an incorrect entry it marks as wrong (revealthat.com).
• Timer and progress cues. A timer tracks your solve time, and once a digit appears nine times in the grid it is dimmed so you know that number is complete (revealthat.com). These small touches make longer solves easier to manage.

New puzzles are published every day – player guides note the refresh typically lands in the evening ET, with a slightly different time on weekends (monktech.net). In practice, just check each morning: there will be a fresh Easy, Medium and Hard waiting.

Is NYT Sudoku Free, or Do You Need a Subscription?

This is the most common question, and the answer is reassuring: NYT Sudoku can be played with or without a subscription (gameerrors.com). The NYT Games app is free to download and offers new puzzles daily for every skill level (play.google.com).

What the subscription gets you is depth: a Games subscription unlocks the broader NYT puzzle ecosystem and typically includes extras like a fuller archive of past puzzles and additional features. The daily Sudoku puzzles themselves – today's Easy, Medium and Hard – are the free core of the experience. One limitation to know: unlike the NYT Crossword, Sudoku does not come with a big public archive of past puzzles; you generally get the current day's set (revealthat.com).

No prices or plan details are quoted here because they change – check the NYT Games subscription page for current terms if you want the full archive and extras.

NYT Sudoku Strategies for Each Difficulty

A few techniques carry you surprisingly far. Work through them in order and only move to harder puzzles when the current level feels comfortable.

Easy strategies:

• Scan each row, column and 3×3 box for the number that appears most often, and place the missing one where it can only go (naked singles).
• Work the boxes with the fewest empty cells first – they give up their secrets fastest.
• Fill in "free" cells immediately to shrink the search space for the rest.

Medium strategies:

• Use candidate mode on every empty cell. A full grid of pencil marks turns guesswork into a logic problem.
• Learn hidden singles: a number that can only sit in one cell of a row, column or box, even if that cell has other candidates (thediplomariot.com).
• Look for pointing pairs – when a candidate in a box is confined to one row or column, it can be eliminated from that row or column elsewhere.

Hard strategies:

• Keep your candidate marks accurate; one wrong pencil mark derails a Hard puzzle.
• Learn X-Wing and Swordfish patterns for the moments when basic elimination stalls.
• Ready for a fiercer number puzzle? Our Killer Sudoku guide introduces the cage-sum variant that builds on everything NYT Hard teaches.
• If you are stuck for more than a few minutes, re-verify your givens and early entries – a single misplaced digit is the usual culprit.

General tips that apply at every level:

• Go slowly. There is no penalty for taking your time, and rushing causes most mistakes.
• Keep Auto-Check on while learning, off once you want a real test.
• Solve at the same time each day – the habit builds pattern recognition faster than occasional marathons.
• If three puzzles a day is not enough, our daily puzzle games list has more one-a-day challenges to build into the same routine.
• When a puzzle feels impossible, switch difficulty down rather than hammering at it. Momentum matters more than pride.

NYT Sudoku vs Other Free Sudoku Options

How does it compare with the alternatives? Here is an honest side-by-side based on verified facts:

NYT Sudoku's edge is curation and polish: a small daily set that is always fresh, an ad-free and clean interface, and the ritual of the same puzzle everyone else is solving that day. If you want unlimited puzzles on tap or a deep archive, dedicated sudoku apps may suit you better – but for a daily habit, the NYT version is hard to beat. Prefer paper over pixels?
