These answers describe version 1.1.

Getting started

How do I start?

Tap New game and choose a difficulty, or follow the journey: 32 stages, each introducing one solving technique with a puzzle built for it.

What do the difficulties mean?

The difficulty depends on the hardest technique a puzzle needs, not on how many cells are empty. Easy needs only singles, Medium pairs and locked candidates, Hard patterns like the X-Wing, Expert wings, Swordfish and Jellyfish. Every puzzle has exactly one solution.

Help and coins

Do hints, notes or jokers cost anything?

Your own notes are always free. Each hint or joker lowers the base coins of that puzzle by 5 %, filling in all notes automatically by up to 25 %, and at least 75 % always remain. Daily and journey bonuses stay in full. The auto solver finishes the puzzle for you and pays a quarter of the base coins without bonus; the game shows the exact amount before you use it.

What are coins for?

For the fifteen elements of the temple garden, jokers and auto solvers, music and backgrounds, and an omamori for your daily streak. Coins are only earned by playing, the app has no in-app purchases.

Why is a garden element still locked?

Elements open with the stages of the journey or after a number of puzzles you solved on your own, whichever comes first. The garden shows how many puzzles are still missing.

Daily puzzle

When does the daily puzzle change?

Every day at midnight UTC, with the same puzzle for everyone. Mondays are gentle, Saturdays expert, Sundays bring a diagonal sudoku.

What is an omamori?

If you missed a single day right after a solved one, an omamori bought the next day protects that day and your streak goes on. A protected day keeps the streak alive but adds no day, no seal and no time. Every omamori makes the next one dearer, every five daily puzzles you solve make it cheaper again.

Photo solver

The camera does not read my sudoku.

Lay the page flat in good, even light, keep the whole grid including its border in the picture and avoid strong shadows. Check the digits after reading, you can correct any cell before solving or playing. The solver is made for printed puzzles.

Game Center

My results do not appear in Game Center.

Sign in under Settings › Game Center on your device. Best times only come from puzzles solved without help, and the daily leaderboard only takes the daily puzzle on its own day.

Your progress and device

Is my progress saved? Can I take it to a new device?

Progress is saved on your device and included in its backup. For iPhone and iPad, you can also enable iCloud sync in the app’s settings on both devices, using the same Apple Account. Keep the app open until the sync status confirms it is up to date. An incoming save waits until you leave an open puzzle. If you played independently on both devices, choose which complete save to keep; progress and coins are not combined. Device settings remain local, and offline play still works.

How do I turn off the daily reminder?

In the app's settings, or under Settings › Notifications › Smart Sudoku Zen.

I bought the app on another device.

Download it again with the same Apple Account in the App Store, at no extra cost.

VoiceOver, larger text and less motion
