Bridge Builder Physics

Build budgeted bridges with beams and tension-only cables, then drive three delivery vehicles across thirty physics challenges.

Your goal

Deliver the vehicle across a bridge that stays within the construction budget. Beams and tension-only cables respond differently to the load.

Choose the first delivery, connect grid points with a beam and run a test crossing. Inspect the stress display before editing the bridge.

Triangulate a weak span before adding material everywhere. A cable can carry tension but cannot prop up a joint under compression.

Select or drag between grid points to build; test the bridge, inspect stress and repair.
