Free sudoku online
“Free sudoku online” usually means a simple bargain: open a URL, fill digits, leave when the bell rings. No installer. No “create account to continue.” No paywall after three puzzles. The board above is that bargain — a normal webpage with classic sudoku, plus Pencil, Check, Hint, and Daily if you want them.
Free here means you can play without paying or registering. It is not a promise that every school filter loves this hostname forever. If the page loads, you can play. We will not paper over a blocked network with a sketchy APK.
When
When to use
You searched free sudoku / free sudoku online. Work or school machine, no installs. You bounced from clones that hid the board behind signup.
When not
When not to
Shortest play URL with almost no framing → play sudoku. Rules first → how to play. Locked difficulty → easy / hard. Cages → killer sudoku.
Defaults
Assumptions
Needs a current browser with JavaScript. Classic 9×9 on this URL. Optional PWA only pins a shortcut — you can play forever without installing. Ads (when enabled later) must not cover the grid.
Steps
How
- Stay on this tab; click once if keys feel dead (focus not in the address bar).
- Fill cells; use Pencil / Hint as needed.
- New puzzle for another free board in the current band.
- Jump to a difficulty URL if you came for a locked band.
Worked notes
Examples
- Library laptop, no admin rights → open this page → play; nothing to approve
- Someone texts “free online sudoku” → board loads without an account wall
Watch-outs
Gotchas
- “Free” means no signup / no paywall for play — not “we never show ads forever.” Ads must not cover the board.
- Closing the tab does not upload your run to a global chart. Progress is local.
- Flash is gone. Bookmarks that expect a plugin are fossils.

FAQ
Common questions
Do I pay later?
There is no paywall after three puzzles and no “unlock the board” fee. Play the grid in this tab; optional ads later must not cover the board.
Signup?
No account wall. You do not create an email login to place digits or use Hint.
Download required?
No installer and no app-store hop. A current browser with JavaScript is enough.
Is free a thinner puzzle?
No — same unique-solution generator as the rest of the site. “Free” is about access, not a toy grid with fake difficulty labels.
PWA required?
No. Install only pins a shortcut if you want one; you can play forever without adding anything to the home screen.
