Tap the structure to place a charge. Drag to orbit, pinch to zoom, two fingers to pan.

Nothing here is scripted. Every block is a rigid body. The tower stands because a real load path carries its weight to the ground — cut that path and gravity does the rest.

Cut low, cut wide. Charges only remove the blocks they touch. Take out most of the supports on one level and the mass above has nowhere to go.

Steer the fall. Blow one side first and the centre of mass swings past the remaining supports — the structure topples that way. That is how a real stack is felled.

Use delays. A sequence collapses a building inward; a single simultaneous blast tends to throw debris outward and blows the budget.

Score rewards a complete collapse, a low rubble pile inside the drop zone, no damage to neighbouring buildings, and the least explosive used.
