Daily Sudoku: Today's Free Puzzle

What is Daily Sudoku?

Daily Sudoku is one new puzzle released every day at Medium difficulty. Unlike the regular practice game, where every puzzle is randomly generated, today's Daily Sudoku is the same for every player — so you can race a friend, compare your solve time, or simply build the habit of one puzzle a day.

A new puzzle unlocks after midnight in your own device's local time zone. Finish it to extend your streak, then come back tomorrow for the next one.

How the daily streak works

• Complete today's puzzle to add one day to your streak.
• Miss a full calendar day and the streak resets to zero the next time you play.
• Mistakes don't break your streak. Turn on mistake counting for a challenge, or just retry — only skipping a day matters.
• Your streak is saved locally in this browser, with no account needed. Clearing your browser data or switching devices will reset it.

Daily Sudoku FAQ

What is Daily Sudoku?

Daily Sudoku is a new Sudoku puzzle released every day at Medium difficulty. Everyone who plays on intosudoku that day gets the exact same puzzle, so you can compare your time with friends.

When does a new daily puzzle come out?

A new puzzle unlocks at midnight in your own local time zone. Your device's clock decides when the puzzle changes, not a fixed server time.

How does the Daily Sudoku streak work?

Your streak counts consecutive days you've completed the daily puzzle. It only breaks if you miss a full calendar day — mistakes or restarting the same day's puzzle never reset it. Your streak is saved locally in your browser.

Will I lose my streak if I clear my browser data?

Yes. The streak is stored only in your browser's local storage on this device, with no account or server involved, so clearing site data or switching devices/browsers resets it.

Can I replay a previous day's Sudoku?

The Daily Sudoku page always shows today's puzzle. To solve a puzzle at your own pace with no daily limit, play a regular Easy, Medium, Hard or Expert game instead.

Is Daily Sudoku free?

Yes, completely free with no sign-up. It runs in your browser and your streak is kept on your device.
