Bridge Builder: Spanwise

Design your own bridge from road, wood, steel, and cables, then tap Test and watch whether it holds as cars, minibuses, buses, and trucks roll across.

Spanwise is a physics bridge-building puzzle with honest simulation: the same design always gives the same result. Beams under heavy load glow yellow, then red, weak bridges start to sway, and when one collapses you see exactly which beam snapped and why.
