Frequently asked questions
How do hints work?
Free players get 3 hints every day and 5 welcome hints once. You can earn more by watching an optional video (up to 5 a day), or buy a hint pack. A hint shows the next move. Sluice Pass gives unlimited hints.
What do stars and par mean?
Par is the fewest moves a level needs. Solve it for one star; match par for three stars. Using a hint keeps a level at two stars.
What are the daily puzzle and the streak?
A new puzzle appears every morning. Solve it on the day to grow your streak.
How do I restore my purchases?
Open Settings and tap Restore purchases while signed in to the same Apple ID or Google account.
Why does the app show videos, and how do I remove them?
Loopsluice has no pop-up ads. The only ads are optional videos you choose to watch for a free hint. Sluice Pass removes the video offers. You can reopen the privacy choices from Settings.
Can I change the colors?
Yes. Settings has a color-blind-friendly palette, shapes on gaps and marbles, a high-contrast option, reduced motion and a select-and-step control style as an alternative to dragging.
How do I reset my progress?
Settings, then Reset progress (you type RESET to confirm). This only affects data on your device and never touches purchases.
Where is my data stored?
On your device. There is no account and no Loopsluice server. The app sends anonymous crash and freeze reports to Google Firebase Crashlytics, and, only after the consent step described in the Privacy Policy, a few basic usage events to Firebase Analytics. Google AdMob also receives data when a free player chooses to watch an optional video (see the Privacy Policy). Your phone may include app data in your own iCloud or Google backup.
How do I restore my purchase on a new device?
Open the app’s paywall or Settings and tap Restore Purchases. Make sure you are signed in to the same Apple ID or Google account you used to buy.
How do I cancel my subscription?
Deleting the app does not cancel a subscription. On iPhone/iPad: Settings → your name → Subscriptions → Loopsluice: Ring Marble Puzzle → Cancel (or see Apple’s guide). On Android: Google Play → Profile → Payments & subscriptions → Subscriptions → Loopsluice: Ring Marble Puzzle → Cancel (or see Google’s guide).
How do I get a refund?
Purchases are handled by Apple or Google, so refunds are decided by them. Apple: reportaproblem.apple.com. Google Play: Google Play refund help.
