Stack Defence

Stack Defence turns the classic tower defense formula on its head by giving you a towering, multi-story battlefield. Instead of sprawling mazes, you're working with a compact, three-dimensional stack where every layer matters. Position your ranged units, spellcasters, and siege weaponry to create overlapping fields of fire, then watch as enemies climb from all sides. The challenge lies in balancing offensive power with structural integrity, as each new tower you add makes the stack taller and more vulnerable to specialized attackers. As you progress, you'll earn resources to upgrade your towers, unlock new unit types, and adapt to increasingly cunning enemy tactics. With dozens of levels, a variety of difficulty settings, and a quick-fire pace, Stack Defence rewards careful planning and quick thinking. The intuitive drag-and-drop controls and clean, modern visuals make it easy to jump in, while the deep strategy will keep you coming back for more.
