Daily sudoku
Daily sudoku here means one seed tied to your device’s local calendar day — open Daily (or this page’s daily lock) and get today’s board, not an endless random reshuffle. Progress stays local. There is no cloud streak account and no newspaper brand mirror.
Difficulty sits in an everyday / medium-ish band so the daily habit stays finishable. Want a random hard fight instead? Open hard or evil and hit New puzzle.
When
When to use
You searched daily sudoku; you want the same board if you refresh today; short daily habit.
When not
When not to
You want endless random boards → play sudoku / home + New puzzle. You want a locked brutal band every time → evil / extreme. You want a NYT-style branded experience → we are not that.
Defaults
Assumptions
Day boundary = your device local date. Switch timezones or devices and “today” can differ — that is local seeding, not a bug in the cosmos. Unique solution. No verified global leaderboard.
Steps
How
- Open this page so the seed matches today’s local date (Daily lock).
- Play with Pencil / Hint / Check as usual.
- Refresh later today → same daily board (until the local date rolls).
- Tomorrow → new daily seed. For a different band anytime → difficulty URLs + New puzzle.
Worked notes
Examples
- Morning commute start; evening resume same day → same daily grid on that phone browser
- You hit New puzzle by habit → you left the daily seed; press Daily again to return
Watch-outs
Gotchas
- We are not a newspaper sudoku franchise.
- Clearing site data wipes local progress — not a paywall.
- “Daily” on portal sites often means “another random puzzle with a calendar icon.” Here the seed is date-locked locally.

FAQ
Common questions
Same puzzle all day?
Yes, for that device’s local calendar date while Daily is active. Refresh later today and you should see the same seed until the local date rolls.
Account / streak cloud?
No signup and no cloud streak. Progress and the daily marker stay in this browser’s local storage on this device.
Harder daily?
Daily stays in an everyday / medium-ish band on purpose. For a locked brutal fight, open hard or evil and use New puzzle.
Killer daily?
Cage puzzles live on killer sudoku. Use Daily there when you want a date-locked killer seed; this page is classic digits only.
