Frequently Asked Questions

Pipe Puzzle Waterworks (sometimes shortened to "Pipe Puzzle") is an iOS puzzle game where you build a pipe route from an entry point to an exit point, then run water through the system to test whether the route is sealed.

Yes. Pipe Puzzle is free to download and play, supported by interstitial ads shown after a level ends. If you prefer an ad-free experience, the optional "Remove Ads" in-app purchase disables ads permanently for your Apple ID.

Gameplay itself works fully offline — levels are generated on-device and your progress is stored locally. An internet connection is needed to load ads after a level ends and to process the optional in-app purchase. If you have purchased Remove Ads (or are simply offline), the App keeps working without a connection.

Pipe Puzzle itself does not collect personally identifying information. Records and settings are stored only on your device. The bundled Google AdMob SDK may use your device's advertising identifier to deliver more relevant ads if you grant tracking permission via Apple's standard prompt — see the Privacy Policy for full details.

Place pipe pieces onto the board, rotate them into a connected route, and press Run. If water reaches the exit without leaking, the level is complete.

The board floods when water reaches an open pipe side or a route that is not sealed. Adjust the pieces and try again.

Each level can store the best local completion time. If you use a hint, that run is not eligible for a record.

Hint shows the intended solution path. It is useful for learning or testing, but it disables record eligibility for that run.

Music volume, sound-effects volume, haptic feedback, visual theme (light, soft, dark), high-contrast mode, reset records, restore purchases, and re-open the privacy / tracking choice dialog.

Pipe Puzzle runs on iPhone and iPad with iOS 17 or later.

Open Settings and use Reset Records. This removes local best times from the device.

The free version shows a short interstitial ad after a level ends, served by Google AdMob. To remove ads permanently for your Apple ID, tap the "Remove Ads" purchase in Settings. If you have already purchased Remove Ads on another device, tap "Restore Purchases" to reactivate it.

iOS asks once whether the App may use your device's advertising identifier. You can change this any time at iOS Settings → Privacy & Security → Tracking. If you live in a region where the GDPR consent dialog is shown, you can also re-open it from Pipe Puzzle's in-app Settings.
