Tilt puzzle

Quiet Gravity

One tap. Everything rolls.

Tilt the walnut board, roll the glass marbles, clear it. Relaxing, with no time pressure. You never steer a single marble, only the direction — and gravity always follows your last tilt.

The rule

Understood in ten seconds

  1. Tap an edge

    The board visibly tilts that way and stays slightly tilted. The edge arrow shows where gravity is pulling right now.

  2. Everything rolls at once

    Every marble rolls until it stops and closes up the gaps. After a tilt to the left they all hang against the left wall.

  3. Three alike burst

    Three or more marbles of the same colour that touch will burst. The rest roll after them — the whole chain reaction counts as one move.

  4. Clear the board

    You are scored on moves. Three stars go to the tightest solution. A move that changes nothing is not counted.

Four marbles

Colour alone never decides

Four colours, four marks

Every marble carries a sandblasted mark: circle, diamond, triangle, bar. If you have trouble telling colours apart, the shape tells you the group. In “High contrast” mode the marks and edges stand out further.

Release

For iPhone and iPad

The Quiet Gravity app icon: the corner of the walnut board with four glass marbles.

Quiet Gravity is coming to iPhone and iPad, and to Android later. The release date will be announced here.

You buy Quiet Gravity outright — you don’t pay for it with ads. The first levels and the daily puzzle are free. A single purchase at €4.99 unlocks all the levels that follow, the endless mode and everything later — once, with no subscription, no coins and no shop.

Quiet Gravity 1.0 has no advertising: no banners, no interstitials, no rewarded videos. The purchase sits beside the saved game and applies offline; “Restore purchases” only sets it and never deletes anything.

The purchase is made through the App Store or Google Play; their terms and refund rules apply.
