About this tool
Bridge Builder is a free online game. Link nodes with beams to span the gap, then test-drive a car safely across. Play instantly — no install, no waiting. It runs entirely in your browser — no download or sign-up needed.
The screen shows a canyon or river that needs to be built between the two sides. You have a limited number of wooden poles and steel cables, and click on the connections between the nodes to build. After the construction is completed, click the test button, and the vehicle will pass over the bridge. The bridge needs to bear the weight of the vehicle.
The load bearing of the bridge depends on the structural design: triangles are the most stable, and quadrangles are easy to deform. Materials have an upper limit for load-bearing, which will break if exceeded. The goal is to allow all vehicles to pass safely and with minimal material consumption.
The physics engine simulates gravity, tension and pressure. The connection between nodes displays the stress color according to the force situation (green safe, yellow warning, red is about to break). Optimize the structure through all vehicles with minimum material.
Bridge building game, building bridges with limited materials to allow vehicles to pass safely, testing structural mechanics and material allocation strategies.
