Frequently asked questions
How do I complete a puzzle?

What if I get stuck?
Look for a route that covers every edge without repeating it; if available in your app version, use Restart or a hint.
Does One Line Draw work without internet?
Core puzzle play is designed to work offline. Ads, updates and external links may require a connection.
Do I need to create an account?
No. The game has no account-registration or login requirement.
How do I clear my progress?
Open Android Settings → Apps → this game → Storage & cache → Clear storage / Clear data. Menu names vary by device; clearing data resets local progress and preferences.
Why are ads not displayed offline?
