About Daily Sudoku
Daily Sudoku is a fixed once-per-day challenge for players who enjoy sharing one clean puzzle with everyone else. The board uses the current date as its seed, which means the same day always produces the same Puzzle ID and the same medium challenge for all players.
There is no backend and no account requirement. You open the page and today's puzzle is ready immediately in the browser.
How the Daily Puzzle Works
The daily seed is built from the current date in the format YYYYMMDD. For example, March 13, 2026 becomes Puzzle ID 20260313. That keeps the daily challenge predictable, easy to reference, and simple to share with one clean URL.
- One day means one shared puzzle for everyone.
- The puzzle changes automatically when the date changes.
- The daily challenge stays fixed at medium difficulty.
Why Play the Daily Challenge
A daily puzzle adds rhythm to Sudoku. Instead of deciding what to open, you get one clear challenge for the day. That makes it easier to build a small habit, compare solve times with friends, or revisit the site for a steady logic break.
