NYT Games Sudoku: Difficulty Tiers and Free vs Paid

NYT Games Sudoku is a digital version of the classic 9x9 number-placement puzzle, offered in three difficulty tiers — Easy, Medium, and Hard — with a new board generated for each tier every day. The Easy tier is generally free to play without a subscription; Medium and Hard typically require a Games subscription. If you want unlimited Sudoku without tier restrictions, Puzzle Theory's Sudoku is free at every difficulty, every day.

How the puzzle works

The rules are the same as classic Sudoku, digitized with built-in error checking:

• Fill a 9x9 grid so every row, column, and 3x3 box contains the digits 1–9 exactly once
• Some cells start pre-filled as fixed clues
• The app typically flags conflicting entries in real time, so you know immediately if a number breaks a row or box

Because the app checks your work as you go, NYT's version is more forgiving to experiment with than a printed puzzle — you can try a number and get instant feedback rather than working out a full logical proof before committing.

Easy, Medium, and Hard: what actually changes

The three tiers differ mainly in how many cells start filled and how advanced a technique you need to make progress:

1. 1Easy — heavily pre-filled, solvable almost entirely by scanning rows and columns for the only possible digit in a cell
2. 2Medium — fewer starting clues, usually requiring you to track candidate numbers across multiple cells before committing
3. 3Hard — the fewest starting clues, often needing multi-step logical deduction techniques and careful elimination across the whole board rather than isolated cells

If Easy feels too slow and Hard feels like guesswork, Medium is usually the tier where actual technique-building happens — it forces you to reason without leaning entirely on obvious single candidates.

What's free vs. what needs a subscription

Generally, the Easy tier is accessible without paying, while Medium and Hard sit behind the Games subscription alongside the rest of the paid catalogue like the full Crossword archive. This split mirrors the rest of the app — see are NYT Games free for how Sudoku's tiering compares to Wordle, Connections, and the Mini.

If you're weighing whether the subscription is worth it just for the harder Sudoku tiers, how much is NYT Games subscription breaks down the actual monthly and annual cost against what you'd get.

Solving techniques that actually help

Beyond just scanning for obvious single candidates, a few techniques carry you through Medium and Hard boards:

• Pencil marking / candidates — noting every possible digit in each empty cell before committing to any of them
• Naked pairs — when two cells in the same row, column, or box can only hold the same two candidate digits, those digits can be eliminated from every other cell in that group
• Hidden singles — a digit that can only go in one cell within a row, column, or box, even if that cell has other candidates listed
• Box-line reduction — when a candidate digit in a box is confined to a single row or column, it can be eliminated from the rest of that row or column outside the box

Working these in order — pencil marks first, then singles, then pairs — is more reliable than jumping straight to advanced patterns before you've exhausted the simple ones.

A free alternative with no tier gate

If you don't want to hit a paywall the moment Easy stops being challenging, Puzzle Theory's Sudoku offers a full daily board with no subscription and no locked difficulty tiers. It's a straightforward way to keep practicing the same techniques above without waiting for a discount on the paid tiers. Pair it with Domino Regions if you like logic puzzles with a different shape of constraint, or check what are NYT Games for the full picture of how Sudoku fits into the wider lineup.

The bottom line

NYT Sudoku splits into three tiers by difficulty, with Easy generally free and Medium/Hard behind a subscription — a structure worth knowing before you assume the whole game is free or the whole game is paid. If tier limits are the sticking point, a fully free daily Sudoku board covers the same techniques without the paywall.
