Frequently Asked Questions
🎮 How do I play One Line?
Draw a continuous line that passes through every dot — without lifting your finger and without crossing the same line twice. Easy to learn, satisfying to master!
⭐ How does the star rating work?
Each level can be solved with up to 3 stars based on how efficient your solution is. Replay any level to beat your best!
💡 I'm stuck on a level — what should I do?
Use the hint button (💡) for a gentle nudge in the right direction. Or take a break — sometimes the answer appears when you stop forcing it!
🎨 How do I change themes?
Tap the Themes button on the home screen. We have 9 themes including Cosmic, Barbie, Bike, and Cricket. Find your favorite!
🔇 How do I turn off sounds or vibrations?
Go to Settings inside the app — you can toggle sounds, music, and haptic feedback independently.
📊 My progress disappeared — what happened?
Game progress is stored locally on your device. Uninstalling the app or clearing app data will reset progress. We're working on cloud sync for a future update!
📢 Why are there ads?
Ads keep One Line completely free for everyone. We try to keep them minimal — banner only on game screen, and one occasional interstitial between levels.
🆕 Will there be more levels?
Absolutely! We're already working on 50+ new levels and additional themes for future updates. Stay tuned!
