About

Stack Attack

Read full description

Stack Attack is an arcade puzzle game set in an overcrowded warehouse. Guide a loader, move crates, and fill horizontal rows. A completed row clears for points, but the crane never waits: cargo arrives faster and faster, and a badly placed crate can end the shift. In Stack Attack, you can: • Move, jump, and push crates with responsive on-screen controls. • Clear complete rows as the pace increases. • Choose the look of your loader, cargo manipulator, and background. • Enable or disable haptic feedback. • Keep a high score saved locally on your device. Start a new shift and bring order to the warehouse.
