Bridge Online
Bridge Online is a building game where every structure you draw must survive an honest physics review. Sketch beams and supports between anchor points with a limited budget, then send a vehicle across your creation, because the engine stress-tests every line in real time and under-engineered spans fold spectacularly under the wheels. Levels raise the stakes with longer gaps, heavier trucks and anchor points that force creative geometry, and leftover budget converts into Vacancyofjob stars. The gap between a graceful arch and a wobbly disaster is one bad triangle. Free in any modern browser.
