Stack Pact: Co-op Blocks

Build one board together. Push connected pieces, mesh rotations like gears, and coordinate every drop online, nearby, or on one device.

One board. Multiple players. Every move matters.

Stack Pact is a cooperative falling-block puzzle where each player controls a different active piece on the same board. Push a connected chain with one move, mesh pieces like gears to propagate a rotation, and coordinate your drops to clear rows as a team.
