## Frequently asked questions

### How do I read an Unisu hint?

Open the relevant area, then the reason, then the concrete move. Enter digits yourself and explicitly accept candidate eliminations.

### Do the three explanation stages use three hints?

No. Stages for one move count together once. There are three hints per puzzle, and you can reopen an explanation already viewed.

### Where are the technique lessons?

Open the app’s learning area and choose a lesson. Guided examples and your own tasks build on that technique’s prerequisites.

### Where are my games stored?

On your device. Games, progress and settings are saved locally; there is currently no cloud sync.

### Can I move a saved game to another device?

Unisu currently has no account-based or cloud synchronization. Do not assume installing it on a new device will restore local games.

### What can I change in settings?

Options include colors, text size, sound and haptics. Choose what suits your display and the capabilities of your device.

### What should I include in a bug report?

Describe the affected screen and what happened immediately beforehand. Your device model, operating system and app version help us reproduce it.

### How can I contact the Unisu team?

Use the website’s contact form or its published email address. We reply to inquiries by email.
