Why a browser Sudoku beats a store app
The average top-10 Sudoku app shows an ad every 1–2 puzzles and requests notifications, tracking and contacts permissions. Zeloku requests nothing. The puzzle engine runs on the edge — the board you tap is generated and verified for a single solution before it ever reaches your phone.

FAQ
- Do I need to download a Sudoku app?
- No. Zeloku runs entirely in your browser — same tap-to-fill board, notes mode, hints and undo as any app, with zero download, zero permissions and zero storage used. Add it to your home screen and it behaves like an installed app.
- Is this Sudoku app really free with no ads?
- Yes. The playing area has no banner ads, no interstitials between puzzles, and no 'watch a video to continue'. There is no premium tier and no account wall either.
- How do I add Zeloku to my home screen?
- On iPhone: open zeloku.com in Safari → Share → Add to Home Screen. On Android: open in Chrome → menu ⋮ → Add to Home screen. The site ships a web app manifest, so it launches full-screen like a native app.
- Does it work offline like an app?
- The daily puzzle loads with the page, so a puzzle already on screen survives a tunnel or a flight. Full offline caching for the archive is on the roadmap — for offline-heavy use, our printable PDF packs are the reliable option.
- What makes this better than Sudoku apps on the App Store?
- Top app-store Sudoku apps monetize attention: ads after every puzzle, streaks behind subscriptions, engagement notifications. Zeloku monetizes nothing — no ads, no dark patterns, a fresh verified-unique puzzle daily, and a real techniques library instead of a gem shop.
