Players stack a variety of items above a bottom plate to reach a height of 625 items. The stack can be composed of different objects, each with its own height and width. Players can add items to the stack by dragging and dropping them onto the growing stack, or by using the keyboard to rapidly add items one at a time.
The objective of the game is to successfully balance the stack without it collapsing. As the stack grows, the center of gravity shifts, and players must continually adjust the objects to maintain stability. The game challenges players to think strategically about weight distribution and spatial awareness.
