Frequently Asked Questions

My progress disappeared. Can I restore it?

Puzzle progress (board state, notes, elapsed time, mistake count, etc.) is stored only on your device. It cannot be restored after uninstalling the app or switching to a new device, so please keep this in mind.

Why do I see ads?

The app is free to use, and displays ads (banner, interstitial, and rewarded video) through Google AdMob. See our Privacy Policy for details on ad-related data.

How does the hint feature work?

With a cell selected, tap the "Hint" button to reveal the correct answer for that cell. You get one free hint per game; after that, you can watch a rewarded video ad to unlock additional hints.
