FAQ
How do I reset my progress and start over?
- Open Android Settings → Apps → One-Rule Tactics.
- Tap Storage → Clear data.
All stars and settings are removed and cannot be recovered.
Will uninstalling remove my progress?
Yes. Progress lives only on your device and we keep no copy. If Google backup is on, Android may restore it when you reinstall.
How do I open the next island?
Each island needs a total number of stars. The stars still missing show on the locked island on the map. Replay earlier levels in fewer moves to earn more.
The timer on the hard islands is too tight.
Go to Settings → Timer and choose Double time, or turn the timer off. The timer also pauses while a dialog is open or you leave the game.
Why can’t I undo?
Islands 1–3 allow any number of undos, islands 4–5 allow up to 3 per attempt, and islands 6–7 allow none. Tap Restart to begin the level again.
What is the “no way to win” warning?
The game tells you when the current position can no longer be won and offers to rewind to the last move that still could. Choose when it warns you, or turn it off, in Settings.
Where do I change the language or turn on the dark theme?
In the game’s Settings: the Language row and the Dark theme row.
Does the game need the internet or collect data?
No. The game plays fully offline and collects no data. When you open these help pages while online, it fetches their latest version from our website. See the privacy policy.
