Rewrite the rules
Shift gravity direction, toggle magnetism, adjust mass, and rotate entire rooms to guide a metal sphere through each chamber.
Physics Puzzle Laboratory
Rewrite the laws.
Roll the sphere.
You do not steer the ball — you reshape the world. Shift gravity, flip magnetic fields, change mass, and trigger chain reactions inside a glowing industrial factory.

How It Works
Control physics, not the ball
Each experiment is a puzzle of cause and effect. Flip switches, rotate chambers, and watch complex systems solve the path for you.
Chain reactions
Trigger fans, lasers, portals, water flows, and thermal systems. One switch can set off a sequence that clears the whole puzzle.
Build your own lab
Earn stars, unlock sectors, and design custom experiments in the blueprint editor. Save layouts and test them instantly.
Factory Map
Five sectors. One central core.
Progress through handcrafted experiments from the Magnet Lab to the heart of the factory.
Magnet Lab
Attract and repel the sphere through polarized fields.
Reactor Plant
Heat, pulse, and energy systems reshape every platform.
Space Wing
Planetary pull and orbital motion in zero-gravity chambers.
Energy Block
Lasers, crystals, and timed objectives under pressure.
Central Core
Every law of the universe combined in the final wing.
Privacy Policy
Your data stays on your device
Last updated: July 15, 2026
Big Gravity Factory ("the App") is developed by Big Gravity Factory. We designed the App as a standalone physics puzzle experience that works without an account and without collecting personal information.
Information we collect
The App does not require registration, does not ask for your name or email, and does not transmit gameplay data to our servers. Progress such as completed levels, earned stars, language preference, and saved blueprints is stored locally on your device using Apple's standard on-device storage.
Third-party services
The App does not include third-party analytics, advertising SDKs, or social network integrations. It does not open external websites or track you across other apps or websites.
Children's privacy
The App is suitable for general audiences. Because we do not collect personal data, no child-specific information is gathered, stored, or shared by us.
Data retention and deletion
All saved progress remains on your device until you delete the App or use the in-app "Reset Progress" option in Settings, which clears local game data.
Changes to this policy
We may update this Privacy Policy when the App changes. The revised date will appear at the top of this section. Continued use of the App after an update means you accept the revised policy.
