Sudoku Zero — Offline, No Ads
Number puzzles. Buy once.
$4.99 · Designed for iPad. Not verified for macOS.
No ads. No tracking. No internet required — not even once.
Pay once and it's yours. No subscriptions, no in-app purchases, ever.
No banner ads. No full-screen interruptions. No "watch a video to continue."
Sudoku Zero is built so you can focus on the puzzle. Nothing breaks your
concentration mid-game. No account, no sign-in, no email.
■ Works completely offline
On a plane, underground, or with no signal — it behaves exactly the same.
The app makes no network connections at all, so nothing about you leaves
your device. Your history stays on your iPhone.
■ Buy once, done
No subscription. No in-app purchases. You'll never hit a paywall for hints.
Future updates are included at no extra cost.
■ Three difficulty levels
Easy, Medium and Hard. Every puzzle is generated fresh, so you never
solve the same board twice.
■ Tools that help you think
· Notes — pencil in candidate numbers
· Hints — one cell at a time when you're stuck
· Undo — take back any move
· Highlighting — see the row, column and matching numbers at a glance
· Error detection — spot conflicts the moment they happen
■ Pick up where you left off
Leave mid-game and it saves automatically. Keep several puzzles going
at once and return to whichever you like.
■ Watch yourself improve
Best score per difficulty, completion rate and solve times. Filter by
the last 7 or 30 days to see your progress.
■ Easy on the eyes
Full light and dark mode support, following your system setting.
Optimized for both iPhone and iPad.
■ Four languages
English · 한국어 · 日本語 · 简体中文
One puzzle on a coffee break. One before bed.
If you've been looking for sudoku without the noise, this is it.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
■ iPhone Duo support
The board now adapts to both the folded and unfolded screens.
When unfolded, the board and controls split left and right, and the
board is kept clear of the fold so no cell sits on the crease.
■ Landscape support
Rotate the device and the layout follows. In landscape the number pad
stands beside the board instead of below it.
■ Proper use of the iPad screen
Wide screens no longer leave large empty margins on both sides.
Both the board and the number keys are larger.
■ Board sized to your screen
The board is now sized from the space actually left on each device.
On short screens the number pad shrinks to give the board more room.
