Questions
Is there a release date or an App Store link?
No. The game is not released yet, so there is nothing to download. This page and the App Store listing will say so when that changes.
Do I need an account or an internet connection?
No. Sudoku Dungeon has no accounts and no network code at all. It works in flight mode.
Does it have in-app purchases or ads?
No. The plan is a single purchase, then everything is there. There is no shop and no currency in the game either.
I made a mistake and lost a life. Can I undo it?
No: a wrong digit is refused and costs a life, that is the rule of the game. The Second Chance, Snail Slime and Boot relics and the Shield set soften it, a rest gives lives back, and the lessons explain how to avoid it.
What are Depths?
Every world can be played on ten Depths. Depth 1 is gentle (four lives and two extra clues on every board), Depth 2 is the game as it is meant, and every Depth after that adds one fixed rule. Win a Depth to open the next. The full list.
What is the promise at the start of a run, and how do I check it?
Before your first move the game shows the SHA-256 fingerprint of your run’s secret seed. When the run is over it shows the secret itself and checks that it matches. To check it yourself, put the secret in any SHA-256 tool and compare. How it works.
Can I share my result?
Yes. At the end of a run you can copy your result as plain text, with your world, Depth, stars, route and seed, and paste it wherever you like. The game itself does not send anything.
Is it really never necessary to guess?
That is the promise, and the game checks it for every board. If you ever find a board where you had to guess, please write to us with the seed (shown at the end of every run); that is a bug we want to fix. See how it works.
How do I continue a run I stopped?
Your run is saved after every move. Open the game and choose Resume.
Can I play the same run as a friend?
Yes. A run is decided entirely by its seed; share the seed and you get the same boards and the same relics.
Where is my progress stored? How do I delete it?
In one small file on your device. Deleting the app deletes it. Nothing is sent anywhere and nothing is backed up by the game itself.
Will it be on Android?
Not planned.
Which languages and devices?
English and Dutch, on iPhone and iPad. On an iPad the game stays in portrait and uses the wider screen for the board, the map and the choices. Large text, a calm mode without movement and screen reader labels are in Settings.
Is there sound? Can I turn it off?
Yes: sound effects and music, each with its own switch in Settings, and softer in calm mode. Everything is made for the game and nothing is downloaded.
