Slide until stopped
Loose pieces travel in the chosen direction until they meet a wall, the hull, or another piece. Nothing stops halfway.
Field manual
Every direction is a decision.
Gravity Station gives you one verb and then spends a thousand stages proving how much can be built on top of it.
The rule
You move the room, not the pieces.
Every object on the board obeys the same vector at the same time. That is the whole game — and the reason a five-piece chamber can take twenty minutes.
Gravity console
Try the mechanic
You never drag a piece. Pick a direction and everything loose slides that way until something stops it. Park the Gravitron and the energy core on the two mounts.

Mount
Debris
Hull
Solvable in seven moves. The game ships with a thousand chambers built on this one rule — and arrow keys work here too.
The Gravitron
The shining core stabiliser. Get it onto a mount and gravity holds — it is the piece the whole station is waiting on.
Energy cores
Charge cells that also have to reach a mount. Useful, fragile, and always in the Gravitron's way.
Par and stars
Every stage has a target move count. Beat it for three stars; scrape through for one.
Undo and hint
A limited undo stack and an optional hint for the chamber you have stared at for ten minutes.
Expanding boards
Grids grow from 6×6 to 15×15 as the campaign climbs, and the piece count grows with them.
Local records
Best move counts, run history and a local Top 10 — all stored on the device.
Obstacle catalogue
What the station throws back.
New hazards arrive in layers. Each one changes what a direction means rather than just blocking a square.
Laser grids
Beams cut lanes across the chamber. Slide a core through one and the run ends.
Portals
Paired gates. A piece entering one leaves the other, still travelling, still under the same vector.
Wormholes
One-way jumps that drop a piece somewhere the direction alone could never reach.
Black holes
Anything that slides in is gone. Sometimes that is the mistake; sometimes it is the solution.
Moving debris
Loose station wreckage that answers gravity too, and gets in the way while it does.
Sun hazards
Heat cells that punish the long slide. Route around them or arrive with fewer pieces.
Game modes
Four ways in.
The campaign is the spine. The other modes are what you play once the spine stops being difficult.
Campaign — 1000 stages
Easy, Medium and Hard paths through the full station. Difficulty changes the layouts, not just the timer.
Daily
One fixed chamber a day, the same for everyone, scored against your own history.
Endless
Generated chambers that keep escalating until you miss. No finish line.
Hardcore
Tight par, no forgiveness, one wrong vector ends the run.
Zen
Timer off, pressure off. The same puzzles with room to think.
Accessibility
Colour, audio, motion and control options in Settings, plus full offline play.

Questions
Before you install.
Is Gravity Station free?
Yes. It is a free download with no in-app purchases, no subscriptions and no advertising.
Does it need an internet connection?
No. The whole game runs on the device. There are no accounts, no cloud saves and no online services to be offline from.
Is there an iPhone version?
Waiting for review. The iPhone & iPad page will be updated.
How long is the campaign?
1000 stages. Early chambers take under a minute; late Hardcore chambers do not.
Does it collect any data?
No analytics, no advertising identifiers, no personal data. Progress is stored locally on your device. See the privacy policy.
What is the Gravitron?
The Gravitron is the core stabiliser — the shining unit that has to reach a mount before the station's gravity core can hold. It is the piece you are really solving for in every chamber, and it is what B-17 is carrying in the last ninety seconds of the short film.
What is the short film?
A five-minute animated short set on the same station, following B-17 through the core failure. It is on the Movie page.
