Stack is a casual strategy game built around placing and balancing blocks, with two modes that put different demands on careful control. In Height Challenge, the aim is to raise a tower as far as possible before it becomes unstable and falls. Special cubes can help you build higher, making each placement part of a push for height.
Balance Challenge shifts the focus from a growing tower to a hand-held platform. Falling blocks must be balanced and stacked in the required quantity to advance. Flawless performance earns score multipliers, while the mode grows harder and calls for quick reactions and hand-eye coordination. The contrast gives Stack a clear split: one mode tests how high you can build, while the other makes steady balancing and clean execution central.
The game is listed as VR-only, with tracked-controller support and two movement options: grab to move, or slide and touch to move. An optional interactive tutorial introduces the controls, and a performance tracker records statistics such as best scores.
