BRINKSTACK is a turn-based physics stacking game about building higher without bringing everything down. Place block pieces on an unstable semicircular base, watch the structure settle, and decide how much risk to take on your next turn.

BUILD ON AN UNSTABLE BASE

The foundation rocks under the weight of every piece. A placement that looks safe can shift the entire stack, so angle, balance, and timing all matter.

MATERIALS CHANGE THE PUZZLE

Wood, metal, stone, and plastic have different weight and friction. Read the current stack, use each block's properties, and find a position that can survive.

CONTROL EVERY PLACEMENT

Move and rotate the active block, give it a light tap, or replace it a limited number of times before committing. Once placed, it becomes part of the physical stack—and any movement can spread through the whole structure.

PLAY SOLO, LOCAL, OR ONLINE

• Keep building in Single Play and push your best height and score.

• Share one screen in turn-based Local Matches for 2–4 players.

• Face one opponent online through Steam Quick Match or invite a friend to a Private Match.

DON'T BE THE ONE WHO TOPPLES IT

Weight, height, and the base's tilt contribute to your score, but score does not decide the winner. In multiplayer, the player whose placement causes the stack to collapse loses.
