How puzzles work
Every puzzle on Fun Puzzles — Sudoku and Word Search — is generated and solved entirely in your browser using JavaScript. Nothing you enter is ever sent to a server. We have no accounts and no database.
Local progress storage
Your progress on today’s puzzle (and whether you’ve completed it) is saved using your browser’s local storage, on your device only — it’s never transmitted anywhere, and it’s automatically superseded once a new day’s puzzle is generated.
Analytics
We use privacy-focused, cookie-free web analytics to understand aggregate traffic. This doesn't collect personal data or track you individually across sites.
Advertising
This site may show ads served by Google AdSense. Google and its advertising partners may use cookies or similar technologies to serve ads based on your prior visits to this or other websites. You can learn more about how Google uses this data at policies.google.com/technologies/partner-sites, and opt out of personalized advertising through Google Ad Settings.
Cookies
Fun Puzzles itself does not set any cookies. Third-party services embedded on the site — currently Google AdSense, when active — may set their own, subject to their own privacy policies linked above.
