A board of walnut, marbles of glass — and one rule: wherever you tilt the board, gravity follows. Tip it to one side, and every marble rolls that way. When marbles of the same colour meet, they vanish, sometimes in a chain. Clear the board in as few moves as you can. Quiet Gravity is a puzzle for people who want to think without being rushed. No timer pushes you to hurry, no life system makes you wait, no ad interrupts a move. Every puzzle can be solved — the only question is how well. The level path grows slowly from one simple rule to full boards with several colours, walls and special pieces. Alongside it sits a daily puzzle that everyone in the world solves on the same day, and an endless mode where new marbles keep arriving. A large part of the level path and the daily puzzle are free. A single purchase unlocks the rest — for good, no subscription, no recurring cost. There is no advertising anywhere in the game, free or paid, and no data is collected. Quiet Gravity works offline: on the sofa, on the train, on a break.
