The way it plays

A small ritual, shared by everyone.

Each UTC day brings the same seven stones to every player. Move them, rotate them and follow your curiosity. A collapse is another way to discover what holds.

  1. 01

    Place a stone

    Drag from the tray, turn it and find a resting place. Pick it up again whenever you want.

  2. 02

    Find the balance

    Let all seven stones settle. Your best height from three daily attempts counts.

  3. 03

    Share your silhouette

    Keep the moment to yourself, or share a tower and a challenge for a friend.

Gameplay works offline and needs no account. Sound, haptics and quiet motion can be adjusted in the game. On Android TV, a remote or controller takes the place of touch.
