Is NYT Sudoku official?

No. NYT Sudoku on nyt-sudoku.net is an unofficial Sudoku game site.

Are these official NYT Sudoku puzzles?

No. Puzzles are generated by this site or stored from this site generator. Official NYT puzzle data is not scraped, copied, stored, or implied.

Can I play without signing in?

Yes. Guest play is available immediately. Google sign-in is optional for syncing progress when cloud storage is configured.

What is the difference between Daily and Unlimited?

Daily gives one Easy, one Medium, and one Hard puzzle for the date. Unlimited generates more practice puzzles by difficulty.

Does progress save if I close the browser?

Guest progress can save in localStorage on this device. Signed-in progress can sync through Cloudflare D1 when configured.

What does Google login sync?

Google login can sync current games, daily completion, unlimited progress, stats, preferences, and completion history.

A basic hint fills an editable empty cell using the puzzle solution and writes the move to history.

Can I use notes or pencil marks?

Yes. Notes help track candidate digits before placing a final answer.

Why do Easy, Medium, and Hard feel different?

The rules stay the same, but harder puzzles give fewer direct singles and require more candidate tracking.

How to Play NYT Sudoku Online for Free

Start NYT Sudoku online for free with daily Easy, Medium, and Hard puzzles, unlimited generated practice, notes, hints, and optional Google sync.

NYT Sudoku on nyt-sudoku.net is built for immediate play: open the board, choose Daily or Unlimited, and start filling a standard 9x9 Sudoku grid. The site is unofficial and independently generated; it does not use official New York Times puzzle boards, screenshots, or puzzle data.

The goal is the classic Sudoku goal. Fill every empty cell so each row, each column, and each 3x3 box contains the digits 1 through 9 exactly once. Given cells are fixed. Editable cells can hold a final digit, notes, or be erased as you solve.

Start Playing

Choose a mode. Daily gives one Easy, one Medium, and one Hard puzzle for the date. Unlimited creates more generated boards for practice.
Pick a difficulty. Easy is best for warmups, Medium adds tighter candidate work, and Hard expects more careful notes.
Select a cell and enter a digit. Use the on-screen keypad or keyboard input where available.
Use notes before guessing. Pencil marks help you track candidates when a cell could still hold several digits.
Finish by validation, not speed. A puzzle is complete when all rows, columns, and boxes are valid.

Daily and Unlimited

Daily mode is a compact habit: three generated puzzles per date, one each at Easy, Medium, and Hard. It gives returning players a simple routine without needing a large archive at launch.

Unlimited mode is practice. Use it when you want another board at the same difficulty, when you want to drill notes, or when the daily puzzle is already done.

Saving Progress

You can play as a guest. Guest progress and preferences may be stored in this browser with localStorage. If you sign in with Google, the site can sync progress, completion state, stats, and preferences through the site's Cloudflare D1 storage when configured.
