## Description

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.
