Gravity Stack: Break the Shape

Gravity Stack: Break the Shape is a physics-based stacking puzzle about controlling mass, height, and structural risk.

Drop squares, triangles, and circles into the chamber. Match two pieces of the same shape and size to break them, earn points, and reduce the mass connected to the floor. Larger pieces are heavier, so every drop changes the structure.

FEATURES

• 21 distinct pieces across three shape types and seven sizes

• Physics-based stacking, collisions, and rotation

• Mass and height-based game-over rules

• An exact matching piece is guaranteed within three drops during a load warning

• Solo play with automatic pause when switching windows or tabs

• LAN and online room-code multiplayer for up to four players

• Turn-based multiplayer with individual scores and penalties

• Keyboard and touch controls

• A single-file Windows build with no separate game installation

HOW TO PLAY

Stack pieces without allowing the floor-connected structure to reach a total mass of 52.5 or cross the 80% height limit.

Two pieces break when they have the same shape and size. Breaking a pair awards points and removes its mass from the structure.

During a load warning, an exact matching piece will appear within the next three drops.

MULTIPLAYER

Create a room and share its short room code with up to three other players. Players take turns dropping pieces.

• Reaching the height limit: -1,000 points

• Exceeding the mass limit: -6,000 points

LAN multiplayer works without an external server. Online multiplayer requires an internet connection.
