How the game works

REBOUND is a one-shot precision puzzle: aim at the rebound rail, release, and break the blue targets on the way out and the orange ones on the way home. There are 90 handcrafted campaign levels across six worlds, a Daily and Weekly Rebound, and Endless Rebound, where every stage is checked to be solvable before you see it. The game works offline, has no timers and no energy system.

Stuck on a level?

• Watch the return path: many levels are solved on the way home, not on the way out.
• After a few misses the game offers a hint. Hints are optional and can be earned by watching a rewarded ad; nothing is ever locked behind a purchase.
• Retry is always available and instant. Medals reward fewer shots, but any clear unlocks the next level.

Purchases

Remove Ads and Supporter Pack are one-time purchases. There are no subscriptions and no consumable currency.

• Restore a purchase: open the game's store screen and use RESTORE PURCHASES while signed in to the same Apple ID or Google account you bought with.
• Refunds are handled by the store, not by us: Apple at reportaproblem.apple.com, Google Play at play.google.com/store/account. After a refund the purchase is removed from the game the next time it syncs.
• Purchase not appearing? Check your internet connection, use RESTORE PURCHASES, then email us with the store receipt or order number.

Ads

Ads come from Google AdMob, with partners such as Unity Ads bidding inside AdMob. There are no ads during play and none in the first ten levels; rewarded ads are always optional. Ad consent choices (where they apply) can be reopened any time in Settings → Privacy → PRIVACY CHOICES.

Gameplay statistics and crash reports

These are off on a clean install. The game asks once, after your first completed level, and you can change the answer any time in Settings → Privacy → GAMEPLAY STATS & CRASH REPORTS. Switching it off stops statistics immediately; crash reporting can take effect from the next launch, and crash information recorded while it was off may stay on your device and be sent if you switch it back on. This switch does not stop advertising data processing — see the Privacy Policy.

Progress and saved data

Progress, settings and your privacy choices live on your device. Version 1.0 has no account and no cloud save, so progress does not transfer between devices. Uninstalling removes local data from the device, although a device or cloud backup you have enabled may keep a copy.

Data access and deletion

Email primequantumstudios@gmail.com with the subject "Privacy" for a data access or deletion inquiry. Please be aware of what is technically possible:

• The game has no accounts, no login and no in-app deletion feature, and it does not display the random identifiers that our service providers use.
• That means we usually cannot link a request to your installation, and we cannot promise that all data will be deleted. We do not claim otherwise.
• What we can do: forward a request to the relevant provider (for example the purchase service) when you can supply an identifier they expose to you, and tell you exactly which provider holds what. Purchase and payment records are held by Apple or Google and are also kept for their tax and accounting obligations.
• What you can do yourself: switch gameplay statistics and crash reports off, reopen your ad privacy choices, reset or delete your device advertising ID, refuse app tracking on iOS, and clear the app's data or uninstall the game.

[A step-by-step deletion procedure will be published here once the developer has finalised it.]

Bugs and feedback

Please include what you were doing, the level number or mode, your device model and OS version, and a screenshot or screen recording if you have one. Crash reports help us most when you have allowed them, but they are never required.
